In the field of remote sensing applications, scientists have developed vegetation indices (VI) for qualitatively and quantitatively evaluating vegetative covers using spectral measurements. The spectral response of vegetated areas presents a complex mixture of vegetation, soil brightness, environmental effects, shadow, soil color and moisture. Moreover, the VI is affected by spatial-temporal variations of the atmosphere. Over forty vegetation indices have been developed during the last two decades in order to enhance vegetation response and minimize the effects of the factors described above. This paper summarizes, refers and discusses most of the vegetation indices found in the literature. It presents different existing classifications of indices and proposes to group them in a new classification.

This chapter evaluates evidence that recruitment dynamics of component species can exert a strong effect on processes at a community level. The chapter first defines settlement and recruitment, and discusses the uses and misuses of these terms in the current literature. Next, it evaluates evidence that rocky intertidal and coral reef fish species can indeed be considered open. Following this, the chapter reviews the dynamics of recruitment, highlighting the differences and similarities between the systems. The consequences of these recruitment patterns to population and community structure, by drawing empirical examples and summarizing existing conceptual models are discussed. Finally, these models and new insights are synthesized into composite models, and predictions and tests stemming from them are suggested. The chapter concludes by addressing the practical or management implications of recruitment and by recommending future research directions. Furthermore, the goal is to draw the attention of workers in other fields to significant findings in these systems, and to promote exchange of ideas between rocky intertidal and coral reef fish researchers. © 1995 Academic Press Limited

In a classical case-control study, Prentice and Pyke proposed to ignore the study design and instead base estimation and inference on a random sampling (i.e., prospective) formulation. We generalize this prospective formulation of case-control studies to include multiplicative models, stratification, missing data, measurement error, robustness, and other examples. The resulting estimators, which ignore the case-control study aspect and instead are based on a random-sampling formulation, are typically consistent for nonintercept parameters and are asymptotically normally distributed. We derive the resulting asymptotic covariance matrix of the parameter estimates. The covariance matrix obtained by ignoring the case-control sampling scheme and using prospective formulas instead is shown to be at worst asymptotically conservative and asymptotically correct in a variety of problems; a simple sufficient condition guaranteeing the latter is obtained. © 1995 Taylor & Francis Group, LLC.

This report describes some of the statistical methods used to analyze data from the National Toxicology Program/Health Effects Institute Collaborative Ozone Project. The purpose of the collaborative study was to assess the health effects of chronic ozone inhalation. Data were obtained from a subset of 164 F344/N rats dedicated to use by the Health Effects Institute from a standard ozone inhalation study conducted by Battelle Pacific Northwest Laboratories for the National Toxicology Program. The study involved eight groups of investigators, each assessing different types of ozone-related health effects. These included studies of respiratory function and of structural, cellular, and biochemical changes in the lungs and airways. Designing and analyzing a study with several groups of investigators raises many statistical challenges. The highest design priority for this study was that each investigation be individually interpretable as an independent study. This meant that each investigator had to receive an adequate number of animals, balanced with respect to level of ozone exposure and other factors such as the gender of the rats and the time they were killed. Another feature of the collaborative study was the opportunity it provided to assess and quantify the effect of ozone exposure on a broad spectrum of endpoints, and to explore the relations between the different types of effect. Maximizing the potential to assess these correlations required that the individual animals studied by the different groups of investigators overlap as much as possible. This aspect of the statistical design required careful consideration of the compatibility between various investigations. Fortunately, the degree of compatibility was substantial. In many cases, for example, it was possible to assess respiratory function in the animals before they were killed, and then to divide the tissue among several different investigators. This report concentrates on the methods that were speciall...

This paper presents the preliminary findings of a novel coating technique for the deposition of hydroxylapatite coatings on ceramic substrates. Through the use of sol-gel methods crystalline coatings of hydroxylapatite on substrates of vycor glass, polycrystalline alumina and single crystal magnesia have been successfully produced. The production of sol-gel solutions, coatings and their analysis was examined by X-ray diffraction, scanning electron microscopy and atomic force microscopy. Results thus far indicate that high quality hydroxylapatite coatings can be produced on ceramic substrates, with coatings deposited in this manner offering a number of benefits over other coating methods. © 1995, Taylor & Francis Group, LLC.

Extracellular nucleotides are potent Ca2+ mobilizing agents.A variety of receptors for extracellular ATP are recognised. Some are involved in fast neuronal transmission and operate as ligand-gated ion channels. Others are involved in the paracrine or autocrine modulation of cell function. Many receptors of this type are coupled to phosphoinositide-specific phospholipase C and, in some cases, other phospholipases. One of these receptors (P2z), however, also appears to operate, at least in part, as a ligand-gated ion channel. Pharmacological data suggest that one nucleotide receptor subtype (currently designated P2u) responds selectively to either a purine nucleotide, ATP, or a pyrimidine nucleotide, UTP. According to an alternative view, ATP and UTP recognise distinct receptors. Because of the diversity of receptors for extracellular nucleotides this may be the case in some cells. Nevertheless, a G-protein coupled receptor that confers both ATP and UTP sensitivity has been cloned, expressed in cultured cell lines and sequenced. This receptor appears to have two ligand binding domains that may partially overlap. The nature of this overlap is discussed and a simple model presented. Activation of the receptor protein via one or other ligand binding domain may underlie some of the more subtle differences between the effects of ATP and UTP. © 1995.

Abstract The stability in number, level, content, and pattern of fears over a one‐year period was examined in Chinese children and adolescents aged 7–17. In addition, perceptions of fear in friends and parents as well as perceptions of the controllability and modifiability of fears were explored as predictors of subsequent fear level. Evidence for moderate stability of fears was obtained. However, stability was qualified by age and sex interaction effects. A developmental‐cultural hypothesis was put forth to account for those findings. Hierarchical regression analyses revealed that perceptions of fears in friends and parents, along with perceptions of the controllability and modifiability of fears, were predictive of fear level at follow‐up. Limitations of the study are noted. Copyright © 1995, Wiley Blackwell. All rights reserved

The daylighting of small interior rooms via skylight and vertical light pipe may be enhanced by deflecting low-elevation light more directly through the light pipe using laser-cut light deflecting panels. Theoretical expressions for light transmission versus elevation through simple light pipes and light pipes coupled to laser-cut panels are developed and compared with measurements using a commercial light pipe. Predictions of hourly illumination levels in typical rooms are obtained. The agreement of theory and experiment justifies extrapolation to very long light pipes, the results of which suggest that light pipes coupled with deflecting panels should be effective in daylighting through several stories of a building. © 1995, SAGE Publications.

The current taxonomy of parasites in the genus Sarcocystis is largely based on morphological characteristics as well as on host specificity and life-cycle structure. Recently, phylogenetic analyses of partial ribosomal RNA (rRNA) sequences provided support for paraphyly of Sarcocystis. We have tested the validity of this hypothesis by sequencing the complete 18S rRNA genes of Sarcocystis arieticanis, Sarcocystis gigantea and Sarcocystis tenella and comparing them with gene sequences derived from other taxa of the phylum Apicomplexa. The results obtained from this study do not reject the hypothesis of monophyly of Sarcocystis species, although the bootstrap data were inconclusive for some species. © 1995, Cambridge University Press.

This article describes the impacts of sensor view and solar zenith angles on two vegetation indices -NDVI (normalized difference vegetation index) and SAVI (soil adjusted vegetation index). An evaluation of these geometric factors on the relationships between these VIs (vegetation indices) and fAPAR (fraction of photosynthetically active radiation absorbed by the canopy) was performed. To accomplish this, an experiment was conducted in Phoenix, Arizona, over plots of bare soil and low, medium, and high alfalfa. Reflectances were measured from 0.4 ?m to 1.0 ?m in nine view angles (from -40° to + 40°, in 10° steps) over varying solar zenith angles. This was done simultaneously with fAPAR measurements. Changes in view angle caused variations in the indices to be as high as 50% in relation to nadir. However, there was an opposite view angle behavior between NDVI and SAVI, with the former increasing from antisolar to forward scattering view direction. A derivative analysis of the indices showed the SAVI to exhibit a more linear relationship than NDVI with the individual bands. The relationships between both VIs and fAPAR were, in general, linear. However, view angle variations perturbed these relationships and caused an over- or underestimation of fAPAR, depending on view direction (antisolar or forward), view angle, and vegetation index (NDVI or SAVI).

We investigate the extension of the nonparametric regression technique of local polynomial fitting with a kernel weight to generalized linear models and quasi-likelihood contexts. In the ordinary regression case, local polynomial fitting has been seen to have several appealing features in terms of intuitive and mathematical simplicity. One noteworthy feature is the better performance near the boundaries compared to the traditional kernel regression estimators. These properties are shown to carry over to generalized linear model and quasi-likelihood settings. We also derive the asymptotic distributions of the proposed class of estimators that allow for straightforward interpretation and extensions of state-of-the-art bandwidth selection methods. © 1995 Taylor & Francis Group, LLC.

There is a consensus of scientific opinion that the activities of man will cause a significant change in the global climate over the next hundred years. The rising level of carbon dioxide and other industrial gases in the atmosphere may lead to global warming with an accompanying rise in sea-level. Mangrove ecosystems grow in the intertidal zones in tropical and sub-tropical regions and are likely to be early indicators of the effects of climate change. The best estimates of predicted climate change in the literature are presented. It is suggested that a rise in mean sea-level may be the most important factor influencing the future distribution of mangroves but that the effect will vary dramatically depending on the local rate of sea-level rise and the availability of sediment to support reestablishment of the mangroves. The predicted rise in mean air temperature will probably be of little consequence to the development of mangroves in general but it may mean that the presence of mangroves will move further north and south, though this will depend on a number of additional factors. The effect of enhanced atmospheric CO2 on the growth of mangroves is unknown at this time but that there is some evidence that not all species of mangroves will respond similarly. The socio-economic impacts of the effects of climate on mangrove ecosystems may include increased risk of flooding, increased erosion of coast lines, saline intrusion and increased storm surges. © 1995 Kluwer Academic Publishers.

Phengite, separated from a metagabbro, three blueschist, and one metabasite that occur as blocks in serpentinite melange in the New England Fold Belt, eastern Australia, has yielded K‐Ar ages of 465 – 480 Ma, significantly older than the age of most components of the belt. The schists and metabasite contain either glaucophane and/or crossite intergrown with the phengite, providing the first conclusive evidence for early Paleozoic subduction accretion associated with the east Gondwana margin. The tectonic affinity of the blocks is uncertain. They and other small early Paleozoic convergent margin elements in the New England Fold Belt may be allochthonous remnants of an arc system accreted in the Devonian or Carboniferous, or they may be related to early Paleozoic convergent margin components found farther inboard in the Paleozoic fold belts of eastern Australia.

Spontaneous multidrug-resistant (Mdr) mutants of Klebsiella pneumoniae strain ECL8 arose at a frequency of 2-2 � 10-8 and showed increased resistance to a range of unrelated antibiotics, including chloramphenicol, tetracycline, nalidixic acid, ampicillin, norfloxacin, trimethoprim and puromycin. A chromosomal fragment from one such mutant was cloned, and found to confer an Mdr phenotype on Escherichia coli K12 cells that was essentially identical to that of the K. pneumoniae mutant. Almost complete loss of the OmpF porin in the E. coli transformant, and of the corresponding porin in the K. pneumoniae mutant, was observed. The presence of the Mdr mutation in K. pneumoniae or the cloned K. pneumoniae ramA (resistance antibiotic multiple) locus in E. coli also resulted in active efflux of tetracycline, and increased active efflux of chloramphenicol. After transformation of a ramA plasmid into E. coli, expression of chloramphenicol resistance occurred later than expression of resistance to tetracycline, puromycin, trimethoprim and nalidixic acid. The ramA gene was localized and sequenced. It encodes a putative positive transcriptional activator that is weakly related to the E. coli MarA and SoxS proteins. A ramA gene was also found to be present in an Enterobacter cloacae fragment that has previously been shown to confer an Mdr phenotype, and it appears that ramA, rather than the romA gene identified in that study, is responsible for multidrug resistance.

We have adapted immunofluorescence microscopy for use in Bacillus subtilis and have employed this procedure for visualizing cell-specific gene expression at early to intermediate stages of sporulation. Sporangia were doubly stained with propidium iodide to visualize the forespore and mother cell nucleoids and with fluorescein-conjugated antibodies to visualize the location of beta-galactosidase produced under the control of the sporulation RNA polymerase sigma factors sigma E and sigma F. In confirmation and extension of earlier reports, we found that expression of a lacZ fusion under the control of sigma E was confined to the mother cell compartment of sporangia at the septation (II) and engulfment (III) stages of morphogenesis. Conversely, sigma F-directed gene expression was confined to the forespore compartment of sporangia at postseptation stages of development. Little indication was found for sigma E- or sigma F-directed gene expression prior to septation or in both compartments of postseptation sporangia. Gene expression under the control of the forespore sigma factor sigma G also exhibited a high level of compartmentalization. A high proportion of sporangia exhibited fluorescence in our immunostaining protocol, which should be suitable for the subcellular localization of sporulation proteins for which specific antibodies are available.

We present biochemical evidence for an intercellular signal transduction pathway in B. subtilis. This pathway governs the conversion of the proprotein pro-θE to the mature transcription factor θE. Proteolytic processing is mediated by the membrane protein SpoIIGA and is triggered by the inferred extracellular signal protein SpoIIR. A factor in conditioned medium from B. subtilis cells engineered to produce SpoIIR during growth triggered processing in protoplasts of B. subtilis cells that had been engineered to produce SpoIIGA and pro-ÏE The factor was also detected in, and partially purified from, extracts of SpoIIR-producing cells of E. coli. We speculate that SpoIIGA is both a receptor and a protease and that SpoIIR interacts with SpolIGA on the outside of the cytoplasmic membrane, activating the intracellular protease domain of SpolIGA.

The test-retest reliability of the survey form of the Leyton Obsessional Inventory-Child Version was examined over a 2-wk. interval. Three age groups of children participated in the study, 8- to 10-year-olds, 11- to 13-year-olds, and 14-to 16-year-olds ( N = 106). For the total Obsessive scores, the test-retest Pearson correlation coefficients for the three age groups were .51, .75, and .83, respectively, which suggest that the temporal stability of the instrument is a function of age.

To examine the reliability of the survey form of the Leyton Obsessional Inventory‐Child Version (LOI‐CV), ascertain the prevalence of self‐reported obsessive‐compulsive behaviour together with age and sex differences and identify the most common obsessive‐compulsive behaviours and their associated level of interference. The survey form of the LOI‐CV was administered to a large sample of children and adolescents attending regular schools. Participants were aged between 8 and 16 years (n= 1602). We found the survey instrument to have adequate internal consistency and test‐retest reliability. There was an age‐related decline in self‐reported obsessive‐compulsive behaviour and girls reported a higher level of obsessive‐compulsive behaviour than boys. The most common obsessive‐compulsive behaviours included: repeated thoughts or words, having trouble making decisions, having to do certain things and doing things in the exact manner and having a bad conscience. For the most part, these behaviours were associated with low levels of interference. However, for a significant minority of youth (5 to 14%), these behaviours did cause problems and significantly interfered with their lives. Although many obsessive‐compulsive behaviours are part of normal development, they may still be problematic for some children and adolescents. Copyright © 1995, Wiley Blackwell. All rights reserved

This selective review shows that childhood obsessive-compulsive disorder (OCD) is a serious condition that requires early identification and treatment. Initially, we examine the relationship of childhood rituals to OCD, and discuss recent findings on the epidemiology of childhood OCD. The DSM-IV criteria for OCD are presented, along with recent findings on psychopathology. Clinical management of childhood OCD is a challenging and difficult task for mental health professionals. We briefly describe and evaluate advances in behavioural treatment — mainly in vivo exposure and response prevention. The adjunctive use of antidepressant medication is also examined. Whilst these clinical innovations are promising, further controlled evaluations are necessary before the efficacy of behavioural intervention can be confidently asserted.

View description>>
The Normalized Difference Vegetation Index (NDVI) equation has a simple, open loop structure (no feedback), which renders it susceptible to large sources of error and uncertainty over variable atmospheric and canopy background conditions. In this study, a systems analysis approach is used to examine noise sources in existing vegetation indices (VIs) and to develop a stable, modified NDVI (MNDVI) equation. The MNDVI, a closed-loop version of the NDVI, was constructed by adding 1) a soil and atmospheric noise feedback loop, and 2) an atmospheric noise compensation forward loop. The coefficients developed for the MNDVI are physically-based and are empirically related to the expected range of atmospheric and background boundary conditions. The MNDVI can be used with data uncorrected for atmosphere, as well as with Rayleigh corrected and atmospherically corrected data. In the field observational and simulated data sets tested, the MNDVI was found to considerably reduce noise for any complex soil and atmospheric situation. The resulting uncertainty, expressed as vegetation equivalent noise, was ±0.11 leaf area index (LAI) units, which was 7 times less than encountered with the NDVI (±0.8 LAI). These results indicate that the MNDVI may be satisfactory in meeting the need for accurate, long term vegetation measurements for the Earth Observing System (EOS) program

The random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) method was used to compare pathogenic and nonpathogenic strains of Entamoeba histolytica. DNA polymorphisms were detected among the different strains and dendrograms were constructed by PHYLIP and PAUP analyses to study the relationship of the strains. Both analyses resulted in identical results, which indicated that pathogenic strains of E. histolytica are closely related and clearly separated from the nonpathogenic strains. The results of this study agree with classification of the strains based on isoenzyme analyses. This suggests that RAPD-PCR is a valuable method in differentiating between strains of this parasite, and the results are consistent with the concept that pathogenic and nonpathogenic Entamoeba represent two different species.

View description>>
Human neuroblastoma (NB) tumor cell lines treated in vitro with the retinoid, all-trans-retinoic acid (aRA), form neurites and undergo growth arrest. Retinoids exert their diverse morphologic effects through a signalling pathway which involves the nuclear retinoid receptors. Defective retinoic acid receptor (RAR) function contributes to the malignant phenotype of several human and experimental tumors. Considerable evidence from gene disruption studies now suggests that one of the RARs, RAR gamma, may directly mediate some retinoid effects on embryonic and malignant cells. We, firstly, examined primary NB tumor tissue for a correlation between endogenous RAR gamma expression and clinical stage of the tumor and secondly, the effects of exogenous over-expression of the RAR gamma gene on a human NB tumor cell line. RAR gamma mRNA expression in 32 primary NB tumor tissue samples were significantly higher in clinically localised tumors compared with advanced or disseminated tumors. The human NB tumor cell line, BE(2)-C, was stably transfected with a mammalian expression vector (pREP4) over-expressing the human RAR gamma cDNA. Two selected clones over-expressing RAR gamma (BE/G1 and 2) exhibited a reduced growth rate compared to control cells. Tumorigenicity was inhibited for BE/G1 cells and there was a delayed onset to tumor formation for BE/G2 cells. aRA caused growth inhibition but not neuritic differentiation of the BE/G clones, while 9-cis-retinoic acid caused both growth arrest and neuritic differentiation. Taken together these results suggest that reduced endogenous RAR gamma expression may contribute to the malignant phenotype of human NB. In NB cells the retinoid signalling pathway for neuritic differentiation may be distinct from that causing growth inhibition.

Logs collected while drilling measured density in situ, through the accretionary prism and decollement zone of the northern Barbados Ridge. Consolidation tests relate void ratio (derived from density) to effective stress and predict a fluid pressure profile, assuming that the upper 100 m of the prism is at a hydrostatic pressure gradient. The calculated fluid pressure curve rises to >90% of lithostatic below thrusts in the prism, presumably due to the increase in overburden and lateral tectonic loading. Thin (0.5-2.0 m) intervals of anomalously low density and resistivity in the logs through the basal decollement zone suggest dilation and perhaps hydrofracturing. A peak in hydraulic head in the upper half of the decollement zone requires lateral influx of fluid, a conclusion consistent with previous geochemical studies. Although the calculated fluid-pressure profile is model dependent, its inherent character ties to major structural features. -Authors

The long-term electrochemical cycling stability of AB5-type compounds in alkaline media can be improved either by lowering the specific surface area of the applied hydride-forming powder or by lowering the oxidation rate constant of the intermetallic compound. Both parameters are shown to be intrinsic material properties. Reducing the specific surface area can be accomplished by making use of non-stoichiometric compounds in which the A-type atoms in the crystal lattice are partly replaced by dumbell pairs of B-type atoms. Electrochemically stable non-stoichiometric compounds are characterized by the absence of a clear discrete α-to-β phase transition upon hydridization, through which particle size reduction of the powder during electrochemical activation remains limited. Compounds with a composition close to or above the as-denoted "critical composition" meet this requirement. On the other hand, lowering the oxidation rate constant can successfully be achieved by replacing part of the A-type atoms by other lanthanides and/or part of the B-type atoms by other transition metals within the AB5 stoichiometry. This leads to so-called multicomponent compounds. Although the hydride-formation/decomposition reaction mechanism for this type of compound is shown to be accompanied by a pronounced discrete phase transition, a relatively low oxidation rate constant ensures a good overall electrochemical cycling stability. © 1995.

Using plate counts, total cell counts, and direct viable counts, we examined the fate of cells of Vibrio vulnificus placed into natural estuarine waters during both winter and summer months. Cells inoculated into membrane diffusion chambers and placed into estuarine waters entered into a viable but nonculturable (VBNC) state in January and February, when the water temperatures were low (average, < 15 degrees C). In contrast, when cells in the VBNC state were placed into the same waters in the warmer months of August through November (average water temperature of ca. 21 degrees C), the cells appeared to undergo a rapid (typically, within 24 h) resuscitation to the fully culturable state. These results were independent of whether the cells were in the logarithmic or stationary phase and whether they were encapsulated or not. This study indicates that the inability to isolate V. vulnificus from cold estuarine sites may be accounted for by entrance of the cells into a VBNC state and that recovery from this state in natural environments may result from a temperature upshift.

Gender differences in fear were examined in 693 Chinese children and adolescents. Subjects were asked to rate their own fears, the fears of their best friends, and the fears of "other" classmates using the Fear Survey Schedule for Children - Revised (Ollendick, 1983). Consistent with previous investigations in Western and Eastern countries, girls rated themselves as more fearful than boys. In addition, both girls and boys rated their best friends as similar in number, content, and intensity of fears. However, girls rated their classmates as less fearful than themselves or their best friends, while boys rated their classmates as more fearful than themselves or their best friends. Findings are discussed in terms of gender role expectations and similarity-attraction hypotheses. © 1995 Plenum Publishing Corporation.

Sheep bred for resistance (R) or susceptibility (S) to fleece rot and myiasis (blowfly strike) were experimentally infected with L. cuprina larvae. Exudates released from the wound site were collected during the infection at 6, 12, 18 and 24 h. The exudates were separated using two-dimensional gel electrophoresis, and proteins were silver stained and identified by immunoblotting with specific antibody and by their isoelectric points and molecular weights. Comparisons of exudate composition were made over time and between R and S sheep. Between 6 and 12 h post larval implantation the exudate was rich in IgG and fibrinogen, which is before extensive tissue damage and suggests that the exudate is not simply tissue haemorrhage but the result of an inflammatory response by the sheep to L. cuprina. The exudate grew in complexity between 12 and 18 h and contained a maximum of 74 distinct peptide spots by 24 h. Exudate from wounds on resistant sheep contained many more peptides in the first 12 h of infection, suggesting a more rapid inflammatory response. The source of proteins from the exudate remains speculative; it appears to be composed of many acute-phase proteins, large amounts of immunoglobulin G and proportionally low levels of serum albumin. Exudate composition is likely to be influenced by the local synthesis of acute-phase proteins and perhaps immunoglobulins, selective transport to the infection site and also enzymic degradation by L. cuprina larval enzymes. The more rapid exudation of acute-phase and serum proteins at infection sites on R sheep may allow the inhibition of the establishment of fleece rot bacteria or L. cuprina larvae under natural challenge.

Arachidonate (1-300 μM) mobilized Ca2+ ions from an intracellular store and stimulated the entry of Ca2+ ions from the extracellular fluid in undifferentiated HL-60 cells that had been loaded with Fura-2. The integrated response was biphasic in form: arachidonate liberated Ca2+ ions from the intracellular store first, resulting in a transient increase in cytosolic free Ca 2+ concentration ([Ca2+]i). Ca2+ entry from the extracellular fluid was not evident for a further 1-2 min. At baseline, [Ca2+]i was 48.1 ± 14.0 nM (SEM, n = 5). Upon addition of arachidonate (100 μM), [Ca2+]i rose to a transient peak level of 217 ± 38.6 nM (SEM, n = 5) and a later plateau level of 427 ± 118 nM (SEM, n = 5). Removal of added Ca2+ ions from the extracellular fluid in the presence of EGTA (1.0 mM) had no effect on the initial transient response but abolished the second phase of the response. In HL-60 cells that had been loaded with BAPTA/AM, the initial transient phase of the response was abolished but the elevation in [Ca2+]i due to Ca2+ entry from the extracellular fluid was unaffected. Undifferentiated HL-60 cells also responded to arachidonate (100 μM) with an increase in the release of the lysosomal enzyme β-glucuronidase. Arachidonate-induced β-glucuronidase release from BAPTA-loaded cells or in control cells exposed to Ca2+-free solutions was inhibited by about 50%. In BAPTA-loaded cells that were incubated with Ca2+-free solutions, arachidonate-induced β-glucuronidase release was inhibited by about 90%. LeukotrieneLeukotriene B4 failed to elevate [Ca2+]i in the concentration range 0.01-1 μM and failed to activate β-glucuronidase release in concentrations up to 10 μM. Furthermore, the cyclo-oxygenase/lipoxygenase inhibitor ETYA (100 μM) was without effect on secretion. Consistent with this finding, we found that a large number of unsaturated fatty acids could reproduce the effect of arachidonate on [Ca2+]i and β-glucuronidase release. Fatty acids belonging to the ω-3, ω-6 an...

The presence of retrons was determined by assaying strains for a small satellite DNA produced by reverse transcription called multicopy, single-stranded DNA (msDNA). An msDNA-producing retron appeared to be absent from only one of the strains surveyed. DNA hybridization experiments revealed that retron elements similar to retron Mx162, first identified in Myxococcus xanthus, were found only among members of the Myxococcus subgroup; that is, each of the seven different genera which constitute this subgroup contained a Mx162 homolog. Another retron element also appeared to have a clustered distribution, being found exclusively within the Nannocystis subgroup of the myxobacteria. A retron element of the Mx162 type was cloned from Melittangium lichenicola, and its DNA sequence was compared with those of similar elements in M. xanthus and Stigmatella aurantiaca. Together, the degree of sequence diversity, the codon bias of the reverse transcriptase genes, and the clustered distribution of these retrons suggest a possible evolutionary scenario in which a common ancestor of the Myxococcus subgroup may have acquired this retroelement.

Devonian and Carboniferous rocks within the Hastings Block represent an arc-related basin fill located, out of place, on the outboard margin of the subduction complex and juxtaposed along strike from the fore-arc basin of the southern New England Orogen. The stratigraphic sequence, structural style and history of rocks in the southern part of the Hastings Block differs from that in the northern part of the block. The stratigraphy of the southern part of the Hastings Block consists of a succession of nine formations (eight new) ranging in age from Late Devonian (Frasnian) to Late Carboniferous (Namurian). A further five formations (three new) ranging in age from Siluro-Devonian to Late Devonian (Famennian) are confined to fault-bounded blocks. Three of the latter are probably correlative with parts of the continuous Frasnian-Namurian succession. The Port Macquarie Block is considered part of the southern Hastings Block because it contains two closely comparable formations. Late Devonian formations include the sequential Bitter Ground Volcanics, Birdwood Formation (both Frasnian in age) and the interdigitating Rollans Road/Cowangara Formations (Famennian-earliest Toumaisian), together with the fault-bounded Ellenborough Volcanics, a probable equivalent to the Birdwood Formation, and the Famennian Wallibree Formation and the undated and possibly equivalent Touchwood Formation. These are characterized by the association of basaltic to andesitic volcanics with deep-water turbidites and radiolarian-bearing sedimentary rocks. Whilst there is an overall similarity with coeval units within the Tamworth Belt of the southern New England Orogen, no detailed lithological correlations are possible between correlative formations in the two areas. The Early Carboniferous Kindee Conglomerate, Nevann Siltstone, Pappinbarra Formation and Hyndmans Creek Formation, alternating proximal to distal deep-water turbidites with minor ash-fall tuffs, have an andesitic provenance similar to ...

Local least squares kernel regression provides an appealing solution to the nonparametric regression, or "scatterplot smoothing," problem, as demonstrated by Fan, for example. The practical implementation of any scatterplot smoother is greatly enhanced by the availability of a reliable rule for automatic selection of the smoothing parameter. In this article we apply the ideas of plug-in bandwidth selection to develop strategies for choosing the smoothing parameter of local linear squares kernel estimators. Our results are applicable to odd-degree local polynomial fits and can be extended to other settings, such as derivative estimation and multiple nonparametric regression. An implementation in the important case of local linear fits with univariate predictors is shown to perform well in practice. A by-product of our work is the development of a class of nonparametric variance estimators, based on local least squares ideas, and plug-in rules for their implementation.

Hydroxyapatite Cal0(PO4)6(OH)2 (HAp) is a hydrated calcium phosphate ceramic that closely resembles the chemical composition of bone mineral and is therefore one of the small group of bonereplacement materials classed as bioactive, i.e. capable of bonding chemically with bone [1]. This group includes calcium phosphate ceramics, which, although chemically similar to HAp, are generally more prone to in vitro dissolution [2], and certain calcium phosphate glass compositions [1]. Thus HAp is a prime candidate for bone replacement applications.

The role of CD4+ and CD8+ T cells in the response to intranasal infection with a Mycobacterium avium complex isolate (MAC) was investigated. Depletion of CD4+ T cells by injected antibody exacerbated infection in the lung, spleen, and liver. There were decreased numbers of inflammatory cells in the lungs of CD4-depleted mice and a significant decrease in lung cytotoxic activity. The neutrophil response was unaffected, and in CD4-depleted mice, unlike intact infected mice, these cells were found with large numbers of associated MAC. Purified CD4+ splenic T cells produced gamma interferon (IFN-gamma) in vitro in response to MAC antigen. IFN-gamma production by cultured spleen, lung, or mediastinal lymph node cells was markedly reduced in CD4-depleted mice. In contrast, CD8+ T cells did not produce IFN-gamma in vitro, and depletion of CD8+ T cells from infected mice had no effect on bacterial growth or lung cell activation. Depletion of IFN-gamma by injected monoclonal antibody had effects similar to those of CD4 depletion, namely, exacerbation of infection and decreased lung cell cytotoxicity. We conclude that CD4+ T cells are the main T cells involved in the lung response to MAC infection and that this response is at least partially dependent on the production of IFN-gamma.

Acquired cellular resistance against Mycobacterium avium complex (MAC) infections involves the induction of Th1 type gamma interferon (IFN-gamma)-producing T cells. Interleukin-12 (IL-12) is a cytokine involved in the control of IFN-gamma production by T cells and NK cells. The role of IL-12 in the response to MAC infection was investigated. Depletion of endogenous IL-12 by injection of monoclonal antibody prior to and during intranasal infection with MAC resulted in an 150- to 550-fold increase in bacterial load in lung, spleen, and liver homogenates by 10 weeks postinfection. Depletion of IL-12 abrogated the ability of spleen cell cultures to produce IFN-gamma in response to stimulus with live MAC. IL-12-depleted mice showed a 75% decrease in the number of inflammatory cells entering the lungs following intranasal infection with MAC, with significant reductions in cytotoxic activity and nitric oxide production by lung cells. This work suggests that IL-12 plays a major role in the activation of IFN-gamma-producing cells during MAC infection.

The molecular dynamics statistical trajectory ensemble (MDSTE) method has been employed to study the fragmentation of fullerenes in a cross-beam collision experiment. Differential fragmentation cross-sections and double differential cross-sections of the final time step of the large scale molecular dynamics statistical trajectory ensemble simulation with improved statistics is presented. The envelope of the cross-sections of the small collision fragments (Fullerene multifragmentation: J. Schulte (N ≤ 28)) follow a scaling law with σ(CN) ≈ N-λ, with λ = 1.54. An odd-even alteration with enhanced even number size fragments (N ≤ 12) is found with a change of the alteration sequence starting at N = 15. The small and large fragments of the fullerene collisions are carbon chains and intertwined carbon chains with vibrational excitations close to that of an ideal cluster gas where about 50% of the collision momentum is transferred to internal vibrational energy, and a strong correlation of fragment mean coordination number and their respective excitation has been found. © 1996.

The time-resolved double-differential cross sections of the mass fragmentation and kinetic-energy angular distribution, and the mass-resolved fragment vibrational excitation and mean coordination number have been calculated with improved statistics from the newly available simulation data. The time-resolved double-differential cross sections show the causal order and other details of the fragmentation process. The fragmentation pattern of the small fragment sizes (N≤20) where this simulation has the most reliable statistics is given special attention. © 1995 The American Physical Society.

Tribological studies have been carried out on Nylon 6,6 with particular emphasis placed on the examination of the effect of water on this prolymer. An examination of the sliding friction behaviour of Nylon 6,6 against a steel substrate shows that the friction decreases with increasing load, probably due to the formation of thermally softened interfaces in the contact. After exposure of this polymer to water, dramatic changes to the frictional behaviour of the Nylon are observed; the friction increases with increasing load. From the application of the adhesion model of friction iot is postulated that the observed changes are caused by extensive plasticisation of the Nylon and as a consequence an increase in the contact area. This proposition is confirmed by the reported scratch hardness data. After treatment with water the scratch friction mechanism changes signficantly and a notable reduction in the hardness of Nylon is observed.

The collisions of small nickel clusters of size 2-14 atoms were studied using the classical trajectory method. Three cases were considered: cluster-monomer, cluster-dimer, and cluster-cluster collisions. The interaction between the nickel atoms was modeled by a semiempirical many-body potential based on the second moment approximation of the tight-binding scheme. This potential, which previously has been shown to reproduce a wide range of bulk properties including finite temperature behavior for nickel, was also found to describe the cluster properties very well. Both the internal temperatures of the colliding clusters and the collision temperature were set equal to 1200 K. In each of the cases studied, sticking was the dominant channel of reaction for clusters other than dimer and trimer. The sticking cross section was further found to be well approximated by the geometric cross section obtained using a simple hard sphere model for clusters larger than pentamer in the case of cluster-monomer and cluster-dimer collisions. For cluster-cluster collisions, the hard sphere approximation overestimates the sticking cross section by about 40% for even the largest clusters considered. However in this case also, the observed trend suggests a better agreement for cluster sizes somewhat larger than the sizes considered in this study. The other significant reaction channel observed was monomer evaporation which becomes more frequent and persists for larger target cluster sizes as the size of the projectile cluster is increased. The cross section results in all three cases do not exhibit any dramatic dependence on cluster size, consistent with the experimental observation of smooth and featureless size distributions for nickel and other transition metal clusters. The cluster-monomer collision calculations were repeated by setting the internal temperature of the cluster to 0 K. The lowering of temperature did not lead to any dramatic size dependence. For the 0 K case, the stic...

We have investigated the mitogenic effect of three mutant forms of human insulin on insulin-producing beta cells of the developing pancreas. We examined transgenic embryonic and adult mice expressing (i) human [AspB10]-proinsulin/insulin ([AspB10]ProIN/IN), produced by replacement of histidine by aspartic acid at position 10 of the B chain and characterized by an increased affinity for the insulin receptor; (ii) human [LeuA3]insulin, produced by the substitution of leucine for valine in position 3 of the A chain, which exhibits decreased receptor binding affinity; and (iii) human [LeuA3, AspB10]insulin 'double' mutation. During development, beta cells of AspB10 embryos were twice as abundant and had a 3 times higher rate of proliferation compared with beta cells of littermate controls. The mitogenic effect of [AspB10]ProIN/IN was specific for embryonic beta cells because the rate of proliferation of beta cells of adults and of glucagon (alpha) cells and adrenal chromaffin cells of embryos was similar in AspB10 mice and controls. In contrast to AspB10 embryos, the number of beta cells in the LeuA3 and 'double' mutant lines was similar to the number in controls. These findings indicate that the [AspB10]ProIN/IN analog increased the rate of fetal beta-cell proliferation. The mechanism or mechanisms that mediate this mitogenic effect remain to be determined.

In 1979, China implemented its one‐child‐per‐family policy in order to control its burgeoning population. Subsequently, concern has been raised about the policy and its potentially negative effects on children. In the present study, we examined these presumed effects on 202 adolescents born before the policy went into effect, 290 preadolescents born during the period in which the policy was being implemented, and 239 children who were born after the policy went into effect. Measures of fear, anxiety, and depression were obtained. Contrary to our hypotheses, based on concerns raised by the one‐child policy, children with siblings reported significantly higher levels of fear, anxiety, and depression than only children, regardless of when they were born. For depression, this effect was qualified by a sibling status x age interaction. Children with siblings born after the policy went into effect, or during its implementation, reported higher levels of depression than did only children; however, only children and children with siblings born before the policy went into effect did not differ significantly from one another. Sociocultural factors associated with these findings are explored. Copyright © 1995, Wiley Blackwell. All rights reserved
