In the upper Barnard River district in the southern New England Fold Belt, unconformable contacts separate Early Permian clastic sedimentary rocks from Devonian spilites to the west of the Peel Fault and from chert and siliceous argillite of probable Middle Palaeozoic age to the east of the Peel Fault. In the Comboyne district, 110 km to the east, a similar contact between Early Permian and older rocks occurs. At each locality several thousand metres of pre-Permian erosion is indicated, with uplift, possibly a product of back thrusting, immediately west of the Peel Fault and subduction accretion farther east. Uplift may not everywhere have been synchronous, and the unconformities need not relate to a discrete episode of deformation. Early Permian rocks from either side of the Peel Fault in the upper Barnard River have a common provenance and contain compositionally distinctive detrital augite which is indistinguishable from that in the Devonian spilites, indicating limited post-Carboniferous movement only on the fault. Although the fault separates depositional realms of contrasting character in the Devonian and Early Carboniferous, it does not mark a major Early Permian facies boundary. © Taylor & Francis Ltd.

In two sequential trials, 154 patients were treated with dosages of ifosfamide, ranging between 8 and 18 g/m2 divided over 4 days, with mesna uroprotection. The first was a phase II efficacy trial in 125 advanced sarcoma patients (Antman et al: J Clin Oncol 7:126-131, 1989), while the second was a dose escalation trial involving 29 patients (Elias et al: J Clin Oncol 8:170-178, 1990). In the first trial, patients received 8 to 10 g/m2 ifosfamide either by bolus or continuous infusion. The response rate for the 64 patients receiving bolus administration was 23% compared with 12% for the 60 patients receiving a continuous infusion schedule (P = .09). Of the 154 patients, 144 had sarcoma and had failed at least one previous regimen. Of these 144, 4% responded completely and 23% had a complete or partial response. The maximum tolerated dose of ifosfamide was 16 g/m2 in the second trial. Dose-limiting renal toxicity was observed at 18 g/m2 ifosfamide (Elias et al: J Clin Oncol 8:170-178, 1990). The duration of myelosuppression and the frequency and severity of mucositis and renal tubular acidosis were dosedependent. A median of 11 days (range, 8 to 18) of granulocytopenia (<500/μL) were observed. Thus, autologous bone marrow reinfusion was not required. Severe central nervous system toxicity (transient confusion, hallucinations, and somnolence) was observed sporadically at both low- and high-dose levels. The first four patients on the standard-dose study did not receive mesna because it was unavailable; three developed gross hematuria. In patients who received mesna, hematuria was uncommon. Hematuria in the group as a whole was significantly associated with a lack of uroprotection, but was not associated with prior cyclophosphamide, pelvic radiotherapy, age, or bolus versus a continuous infusion schedule. Patients receiving ifosfamide with mesna uroprotection can tolerate considerable dose escalation over the usual prescribed doses before nonhematologic toxi...

The discovery and study of haemoglobin and its genes in nitrogen-fixing nonleguminous plant root nodules and in the roots of non-nodulated and non-nodulating plants has shown that these haemoglobins, the leghaemoglobins of legume nodules, and animal haemoglobins, all have a common evolutionary origin. It would be simple to assume that they are related by vertical descent from a haemoglobin-containing proto-organism that evolved in the early biosphere some 1500 million years ago, but this might not be so. Recently, haemoglobin has been recognised in Vitreoscilla, a bacterium, and homology between this protein and its gene and animal and plant haemoglobins and their genes is demonstrated. This could mean that bacterial, plant and animal haemoglobins are related by vertical descent from haemoglobin present in a common proto-organism, possibly a primitive archaebacterium, that developed in the early Archean era more than 3500 million years ago. The known properties of contemporary plant and animal haemoglobins and their genes suggest that plant haemoglobin, with its ability to function at nanomolar concentration of free oxygen and its three-intron gene structure, could most resemble this putative primaeval haemoglobin.

Three-year old Norway spruce [Picea abies (L.) Karst.] trees established from two clones (4076 and 2470) of a medium-altitude southern German provenance, were transplanted in May 1986 into two acid brown earth soils which differed particularly in the amounts of exchangeable Ca2+and Mg2+. During the summers of 1987 and 1988 trees were exposed in large-scale fumigation chambers (solardomes) to ozone at 200 or 40 µg-3(control). Each day trees were treated with acid (pH 3-6) or control (pH 5-5) mist solution. In late autumn 1988 certain aspects of tree water relations were investigated. In clone 4076 ozone and acid mist reduced stomatal conductance in the light, but resulted in incomplete stomatal closure at night, reducing the diel range of stomatal conductance in treated trees grown on both soils. In addition, current year's needles excised from clone 4076 dried more rapidly following exposure to ozone and/or acid mist than needles from control trees, indicating impaired stomatal performance. However, evidence of both clonai and soil variation in this response was found. Cellular water relations of current year's shoots of clone 4076 were investigated using pressure-volume analysis. Exposure to ozone and/or acid mist resulted in a marked increase in the plasticity of tissues (reduction in ?) compared with controls, indicating that the pollutants induced cell wall loosening. In trees exposed to acid mist this was associated with lower cellular solute concentrations and a decrease in maximum turgor.

Three-year old Norway spruce [Picea abies (L.) Karst.] trees of clonal stock originating from medium altitude in southern Germany were transplanted in May 1986 into two acid brown-earth soils which differed particularly in the amounts of exchangeable Ca2+ and Mg2+. During the summers of 1987 and 1988 trees were exposed in large-scale fumigation chambers (solardomes) to ozone at 200 or 40 (control) µg m-3 Acid (pH 3?6) or control mist (pH 5?5) solution was applied daily to trees in each half of the solardomes. In late autumn (1988) the light response of CO2 exchange, and the chlorophyll and soluble carbohydrate contents of needles were determined. Ozone and/or acid mist treatment had only minor (< 10%) effects on the light-saturated rate of photosynthesis which were not statistically significant in plants from either soil. Needles from trees raised on the richer soil and exposed to a combination of ozone and acid mist showed a significant increase in the apparent quantum yield of photosynthesis which was associated with an increase in chlorophyll content. Ozone (alone) stimulated the rate of dark respiration by 40 and 58 % for trees grown in richer and poorer soils, respectively, and this was associated with a decrease in ethanol-soluble carbohydrate content of needles. Where significant interactions between ozone and acid mist were found, they were generally antagonistic. The reduction in the ethanol-soluble carbohydrates would be expected to reduce frost hardiness, and may contribute to the increased sensitivity of ozone-treated needles to freezing, which has been reported in previous studies.

Four-year-old, seed-grown trees of Norway spruce (Picea abies (L.) Karst.) were exposed in open-top chambers to charcoal-filtered air (8 h daily mean 54 μg O3 m-3) over three consecutive summers (1986-1988). In mid-May 1988, before the third season of fumigation and more than 7 months after exposure to ozone the previous summer had terminated, daily rates of transpiration from intact shoots and water loss from excised needles were measured together with the amount of wax on the needle surface. In mid-July, 92 days after the beginning of the third year of exposure, the wettability of needles was assessed by measuring the contact angle of water droplets on the surface of needles. Exposure to 156 μg O3 m-3 resulted in a 16% increase in daily transpiration in current year's needles and a 28% increase in 1-year old needles. These effects were associated with slower stomatal closure in response to increasing water deficit in the needles previously exposed to 156 μg m-3 ozone. The long-lasting nature of such ozone-induced effects could predispose trees to drought and winter desiccation. No significant effects of ozone were found on the amount of wax covering the needle surface, but a marked increase in the wettability of needles exposed to ozone was observed. The far reaching physiological consequences of these effects in the field and the possibility that similar disturbances may contribute to the decline of high-altitude forests of Norway spruce in Europe are discussed. © 1990.

View description>>
The uptake of pure non-conjugated fluorescein isothiocyanate (FITC) and of the membrane-impermeant probe FITC-dextran into suspension-cultured carrot cells and protoplasts has been investigated. Commercial samples of a 70K (K=103Mr) FITC-dextran were shown to contain contaminant FITC and/or its degradation products, which were rapidly internalised into the vacuolar system of both cells and protoplasts. However, purified samples of the 70K FITC-dextran were taken up into the vacuoles of cells but not protoplasts after a 1h incubation period. This apparent difference in the ability of cells and protoplasts to internalise FITC-dextrans was confirmed using samples of both commercial and purified 20K FITC-dextran as putative endocytotic probes. Both confocal and conventional fluorescence microscopy of FITC-treated cells have shown that FITC was internalised into similar intracellular compartments as was observed in cells treated with three-times purified 70K FITC-dextran. Thus, FITC was a useful fluorophore for rapidly labelling both the putative endocytotic compartments and the pleiomorphic vacuolar system of carrot cells. Kinetic studies indicated that FITC entered the cell by diffusion in the form of the neutral molecule. We have shown that treatment of cells or protoplasts with the drug Probenecid reversibly inhibited the uptake of FITC from the cytoplasm into the vacuole. In addition, the uptake of FITC into isolated vacuoles was enhanced in the presence of Mg-ATP.

Two-year-old seedlings of Picea rubens, growing in open-top chambers in Scotland were treated twice weekly from July 1987 to December 1987, with mist containing ammonium sulphate and nitric acid at a pH of either 2.5 or 5.0. The response of photosynthesis and stomatal conductance to light flux density and carbon dioxide concentration were measured in March 1989. Leaf chlorophyll a and b contents were also measured. Acid mist (pH 2.5) resulted in several significant changes. First, both the rate of light saturated photosynthesis (Amax) and CO2- saturated rate of photosynthesis (J) were substantially increased, when expressed per unit leaf area. Second, the apparent quantum yield and chlorophylls a and b content increased. Third, as a consequence of the greater chlorophyll content of the leaves treated with acid mist, the rate of Amax, and J, expressed per unit chlorophyll, was substantially reduced in pH 2.5 treated branches. Stomatal conductance was enhanced at all but the highest light flux densities, and was independent of the CO2 concentration, remaining high for all values of CO2 concentration used. These results show that acid mist caused a number of responses in the gas exchange and photosynthetic properties of red spruce.

A pressure-volume analysis of aubergine (Solanum melongena) leaves following water stress was undertaken to determine a possible role of changes in cellular water relations in influencing stomatal conductance responses to water stress. A comparison of two methods of rehydrating the leaves was also undertaken. It was shown that the rehydration of excised leaves did not reveal osmoregulation, whilst rehydration of intact plants did reveal osmoregulation following water stress. An increase in the bulk volumetric elastic modulus and the bound water fraction also occurred in response to water stress. These results are discussed in relation to pressure-volume technique and stomatal conductance responses to drought

CO2 assimilation rate, stomatal conductance and chlorophyll content of current and previous years' needles of Norway spruce were measured in May 1988, 205 days after the cessation of ozone fumigation during the summer of 1987. Rates of assimilation were consistently higher for both needle year age classes for ozone fumigated trees in comparison to control trees, although only statistically significant for part of the day for current year's needles. A 26% and 48% stimulation, overall, in mean daily rates of assimilation for current and previous years' needles of ozone fumigated trees was observed. This was due to an enhanced apparent quantum yield and light saturated rate of assimilation of ozone fumigated trees. The temperature response regression of assimilation versus temperature was also greater, such that at any given temperature, assimilation was higher for ozone treated trees than control trees. Stomatal conductance was greater for ozone fumigated trees than the controls, but this was only marginally statistically significant. Moreover, there was a consistent increase in chlorophyll content in both year classes in ozone-treated trees. These results are discussed in relation to a possible long term effect of ozone fumigation upon the processes of conifer winter hardening and spring de-hardening.

Central nervous system and renal toxicity occurred infrequently, perhaps as a result of the continuous-infusion schedule.

This study describes viral-like RNA molecules that have been detected in two species of Eimeria that infect the chicken. The RNA molecule identified in E. maxima has been characterized: subcellular fractionation studies have shown that the RNA is present in the cytoplasm, probably as an abundant ribonucleoprotein that is insensitive to RNAse A treatment. Electron microscopy has demonstrated that this RNA molecule is double stranded. In addition, all E. maxima strains examined so far contain this RNA molecule. © 1990, Cambridge University Press.

The New England Orogen of coastal central Queensland contains the Wandilla terrane in the west and the Shoalwater terrane in the east and north. Both terranes underwent multiple deformation (D1-D4) and at least one main episode of prolonged metamorphism. The first deformation (D1) resulted from subduction accretion in a Devonian and Carboniferous forearc. Early subduction complex structures in the Wandilla terrane are dominated by steeply dipping melange with lenticular phacoids of tuff and greywacke in a mudstone matrix; whereas in the Shoalwater terrane strata are mainly coherent and the overall structure is inferred to comprise slices repeated by an imbricate thrust system. The second deformation (D2) is widespread in both terranes and formed a mostly subhorizontal to moderately east-dipping cleavage and tight to open F2folds. A strong down-dip stretching lineation was generated in the Wandilla terrane. F2folds and S0-S2relationships have a consistent geometry indicating an antiform to the east. Rotation of bedding, already steeply dipping due to subduction accretion, resulted in overturned strata that are typical of the Shoalwater terrane. D3and D4developed as a progressive sequence during the same general deformation as D2; this occurred in the Middle to Late Permian although farther west its effects continued into the Triassic. © Taylor & Francis Ltd.

Devonian and Carboniferous rocks of the northern New England Orogen developed in a forearc setting in which the Wandilla terrane was part of the subduction complex. The Wandilla terrane shows three episodes of deformation. The first was associated with accretionary processes and formed lenticular and mudseam melange. Lenticular melange was derived from interbedded greywacke and mudstone, bedded chert and greenstone and shows progressive bedding-parallel extension with pinch-and-swell and boudinage. It is characterized by an alternation between zones of semi-coherent beds and zones with total bed disruption. Mudseam melange formed from thick-bedded greywacke units and is characterized by abundant mud injection features and scalloped greywacke contacts indicative of deformation of unconsolidated sediment and mobilization of overpressured mud. Both melange types formed at shallow structural levels in offscraped and imbricated successions. Lenticular melange resulted from stratal extension whereas mud-seam rocks were produced by the injection of overpressured mud into massive sands. The second and third deformations post-dated formation of the subduction complex and gave rise to a variably developed cleavage (S2) and steeply dipping strike-slip faults, respectively. © 1990.

Seventy-four spectral features are tabulated for manganese and a number of new assignments have been made based on pseudo-relativistic Hartree-Fock calculations and quantum defect analysis. A similar study of samarium reveals only a number of broad features in the ejected-electron energy range 8-10 eV.

AbstractA nonlinear systems analysis is applied to cyclone tracks over the North Pacific area (based on surface pressure analyses and twelve‐hourly sampling time) and over the Australian region (based on 500mb heights and daily sampling) for the respective winter seasons. First estimates are obtained of the degree of their chaotic or irregular behaviour in phase space and of the self‐affinity of the planar tracks. This information is deduced from distance distributions (correlation integrals) between independent pairs of cyclone trajectories and from the structure function of individual cyclone paths.The correlation integrals reveal average structures of the substitute phase space (such as the dimension of the attractor, a measure of predictability) after stratifying the North Pacific tracks into a western domain of growing and an eastern domain of large amplitude cyclones. A further subdivision into large‐scale flow anomalies (the positive and negative Pacific/North America pattern in the eastern North Pacific) provides flowdependent estimates which indicate two subsystems differing in dimension and predictability. the time scaling analysis of the planar cyclone paths characterizes systems of no scale preference: the associated variance spectra decrease by a 2 to 3 power law with increasing frequency.

The optical properties of a partially vegetated cotton field with spatially and temporally dynamic soil water conditions were analyzed with coincident aircraft and satellite data. The study was conducted at the Maricopa Agricultural Center in Arizona during June 1988. The dynamics of soil surface drying made it difficult to evaluate plant cover and assess soil condition with combined thermal, brightness, and normalized difference vegetation index (NDVI) spectral parameters as all three parameters were sensitive to the three stages of soil drying. A soil-adjusted vegetation index (SAVI) minimized both spatial and temporal variations in soil spectral behavior and was found useful in vegetation analysis and in further qualitative assessment of soil condition. Due to the complex dynamics of soil surface drying and variability in soil properties, soil water content at the surface (0 - 5 cm) could not be determined with the Thematic Mapper moisture bands, or with the various 'wetness' indicators. © 1990.

Long-term changes of seagrass meadows (Posidonia australis Hook. f. and Zostera capricorni Aschers.) in Botany Bay, Australia, were investigated using historical aerial photography (1930-1985), field observations (1970-1987) and in situ sediment coring for fibrous remains of Posidonia. Aerial photography and field observations indicated that P. australis had undergone a steady decline in distribution in Botany Bay over the past 40 years. Between 1942 and 1984, 58% (257 ha) of Posidonia was lost from the bay's southern foreshores. By 1987, the once continuous meadow of Posidonia consisted of a number of fragmented beds. The decline occurred during a period of industrial and residential development in the catchment, which included the dredging of the bay's entrance to allow passage of large container ships. The dredging caused an increased wave height in many parts of the bay, and resulted in deterioration and erosion of seagrass beds, particularly during storm events. As an example of this process, the effect of minor storms in reducing leaf biomass of Posidonia by 70% is reported. Grazing by the sea urchin, Heliocideras erythrogramma (Valenc.), between 1980 and 1986 was responsible for smaller losses of Posidonia. The existence of fibrous remains in sediment cores offered circumstantial evidence that Posidonia had a much wider distribution in Botany Bay prior to the earliest aerial photography. A history of poor catchment management, uncontrolled effluent disposal and widespread dredging is suggested as the cause for these earlier, unquantified losses. Over the same period (1930-1987), Z. capricorni was found to have undergone cyclical fluctuations in area throughout the bay, and had colonised many sites that were previously vegetated with Posidonia. © 1990.

Surface reflectance factors from bare field soil were measured to determine the relationship between surface soil water content and spectral reflectance. Reflectance in the six reflective Thematic Mapper (TM) bands plus a 1.15 to 1.30 μm bandpass (referred to as MMR 5) was measured using a groundbased radiometer across a soil water gradient provided by a line source sprinkler system. A spectral index of soil brightness (Brightness) derived using the Gram-Schmidt process and utilizing reflectance information was calculated for each band and for combinations of bands. The results of this study show that TM band 7 (2.05-2.30 μm) provided improved estimates of surface soil water content (0-0.5 cm depth) over estimates using reflectance information from all seven bands. Good correlations were also found between band ratio spectral indices of TM 5 (1.55-1.75 μm) / TM 7, MMR 5/TM 7, and MMR 5/TM 5 and surface soil water content. Results indicate that surface reflectance factors within bandpasses that partially overlap water absorption regions, such as TM 7, are most highly correlated with surface soil moisture. Band ratios utilizing a bandpass partially overlapping a water absorption region such as TM 7 and a non-water-absorbing bandpass such as MMR 5 yield close correlations with surface soil water content. © 1990 Springer-Verlag.

AbstractThe teratogenic effect of N2O is of interest because thousands of pregnant women are exposed to this gaseous anesthetic each year. The effects of repeated N2O exposures were investigated for offspring of mice exposed to air or N2O (5%, 15%, or 35%) for 4 hours per day on days 6 through 15 of pregnancy. Ten litters per exposure group were studied. Exposures did not affect reproductive indices, survival, or physical milestones of development. Body weights showed significant exposure effects that could not be isolated to specific exposure groups; however, N2O‐exposed mice tended to weigh more than air‐exposed animals. Brain weights measured on postnatal day (PND) 126 or 127 were not different among exposure groups or between genders. Ability to stay on a rotating rod was not affected by prenatal N2O exposure. Prenatal exposure to N2O resulted in hyporeactivity of the startle reflex in response to acoustic or tactile stimuli. On PND 95 the results were statistically significant for all N2O‐exposed groups compared with the air‐exposed group. On PND 60, although not statistically significant, there was a definite trend toward hyporeactivity for the N2O groups. There was a significant age‐related difference in startle response; control animals were significantly more reactive at 95 than at 60 days of age. Of the N2O‐exposed groups, only the 15% group showed a statistically significant increase in reactivity from 60 to 95 days of age. The risk of behavioral or functional abnormalities for humans following in utero N2O exposure is unknown and cannot be directly extrapolated from the present study. The 4 hour duration of exposure is not unusual for surgical patients, but exposure throughout the period of organogenesi...

Infected-cell protein 27 (ICP27) is a herpes simplex virus type 1 alpha, or immediate-early, protein involved in the regulation of viral gene expression. To better understand the function(s) of ICP27 in infected cells, we have isolated and characterized viral recombinants containing defined alterations in the ICP27 gene. The mutant virus d27-1 contains a 1.6-kilobase deletion which removes the ICP27 gene promoter and most of the coding sequences, while n59R, n263R, n406R, and n504R are mutants containing nonsense mutations which encode ICP27 molecules truncated at their carboxyl termini. All five mutants were defective for lytic replication in Vero cells. Analysis of the mutant phenotypes suggests that ICP27 has the following regulatory effects during the viral infection: (i) stimulation of expression of gamma-1 genes, (ii) induction of expression of gamma-2 genes, (iii) down regulation of expression of alpha and beta genes late in infection, and (iv) stimulation of viral DNA replication. Cells infected with the mutant n504R expressed wild-type levels of gamma-1 proteins but appeared to be unable to efficiently express gamma-2 mRNAs or proteins. This result suggests that ICP27 mediates two distinct transactivation functions, one which stimulates gamma-1 gene expression and a second one required for gamma-2 gene induction. Analysis of the mutant n406R suggested that a truncated ICP27 polypeptide can interfere with the expression of many viral beta genes. Our results demonstrate that ICP27 has a variety of positive and negative effects on the expression of viral genes during infection.

Abstract: Cross‐linked collagen bioprostheses usually are designed to be inert and nonresorbable, resulting in fatigue and wear failure in high‐stress environments. Eventual replacement of the implant, although minimizing strength loss during resorption, would result in a graft with reparative ability. Kangaroo tail tendon (KTT) partially cross‐linked with glutaraldehyde (GA) was evaluated in vitro for resistance to bacterial collagenase digestion and in vivo for biocompatibility and resorbability in an intramuscular implant assay. Cross‐linking was quantified by thermal denaturation studies. Incomplete cross‐linking was achieved with concentrations of GA >0.1% (w/v). KTT cross‐linked in <=0.05% GA were collagenase resistant being incompletely digested after 240 h. Cross‐linking of KTT with low concentrations of GA resulted in partial collagenase resistance and slowed resorption.

This paper considers estimation of a continuousbounded probability density when observations from the density are contaminated by additive measurement errors having a known distribution. Properties of the estimator obtained by deconvolving a kernel estimator of the observed data are investigated. When the kernel used is sufficiently smooth the deconvolved estimator is shown to be pointwise consistent and bounds on its integrated mean squared error are derived. Very weak assumptions are madeon the measurement-error density thereby permitting a comparison of the effects of different types of measurement error on the deconvolved estimator. © 1990, Taylor & Francis Group, LLC.

SUMMARY Hypothesis tests in generalized linear models are studied under the condition that a surrogate w is observed in place of the true predictor x. The efficient score test for the hypothesis of no association depends on the conditional expectation E(x|w) which is generally unknown. The usual test substitutes w for E(x|w) and is asymptotically valid but not efficient. We investigate two new test statistics appropriate when w = x + z where z is an independent measurement error. The first is a Wald test based on estimators corrected for measurement error. Despite the correction for attenuation in the estimator, this test has the same local power as the usual test. The second test employs an estimator of E(x|w) and is both asymptotically efficient for normal errors and approximately efficient when the measurement error variance is small.

AbstractWe derive a class of higher‐order kernels for estimation of densities and their derivatives, which can be viewed as an extension of the second‐order Gaussian kernel. These kernels have some attractive properties such as smoothness, manageable convolution formulae, and Fourier transforms. One important application is the higher‐order extension of exact calculations of the mean integrated squared error. The proposed kernels also have the advantage of simplifying computations of common window‐width selection algorithms such as least‐squares cross‐validation. Efficiency calculations indicate that the Gaussian‐based kernels perform almost as well as the optimal polynomial kernels when die order of the derivative being estimated is low.
