| effect of cations on effective permeability of leaf cuticles to sulfuric acid. | many plants are exposed to prolonged episodes of anthropogenic acid precipitation with ph values of 4 or less, but there is little evidence of widespread direct damage to the plant cells. acids appear to permeate leaf cuticle via charged pores, which act as a fixed buffer that delays but does not stop acid movement. we investigated the effect of cations on the movement of protons through astomatous isolated leaf cuticles of pear (pyrus communis l.) and rough lemon (citrus limon [l.] burm. fils c ... | 1993 | 12231931 |
| patterns of effective permeability of leaf cuticles to acids. | plants in the field are frequently exposed to anthropogenic acid precipitation with ph values of 4 and below. for the acid to directly affect leaf tissues, it must pass through the leaf cuticle, but little is known about the permeability of cuticles to protons, or about the effect of different anions on this permeability. we investigated the movement of protons through isolated astomatous leaf cuticles of grapefruit (citrus x paradisi macfady.), rough lemon (citrus limon [l.] burm. fils cv ponde ... | 1993 | 12231681 |
| two methods of haploidization in pear, pyrus communis l.: greenhouse seedling selection and in situ parthenogenesis induced by irradiated pollen. | seedlings of 12 crosses involving pear varieties or hybrids were observed for the presence of haploid plants. on the basis of phenotypic characteristics, 17 plants corresponded to the haploid condition and, of these, 12 were determined by chromosome counting to be haploid (2n=x=17). in addition, and in order to induce in situ parthenogenesis, several pear varieties were pollinated with a selected clone carrying a homozygous dominant marker gene for the colour of red. this pollen had previously b ... | 1993 | 24190217 |

| concurrent validity of the cognitive component of schizophrenia: relationship of panss scores to neuropsychological assessments. | cognitive symptoms of schizophrenia may represent a separate component of the disorder that is distinct from positive or negative syndromes. in a previous study, we reported a factor analysis of the positive and negative syndrome scale (panss) that revealed five components, one of which we labeled the cognitive component. in the present study, we explored the validity of the panss cognitive component by examining correlations between neuropsychological measures and the five factor-analytically d ... | 1994 | 7701028 |
| protein synthesis and breakdown during heat shock of cultured pear (pyrus communis l.) cells. | cultured pear (pyrus communis l. cv passe crassane) cells were subjected to temperatures of 39, 42, and 45[deg]c. heat-shock protein (hsp) synthesis was greater at 30[deg]c than at temperatures above 40[deg]c and continued for up to 8 h. both cellular uptake of radiolabeled methionine and total protein synthesis were progressively lower as the temperature was increased. polysome levels decreased immediately when cells were placed at 39 or 42[deg]c, although at 39[deg]c the levels began to recove ... | 1994 | 12232178 |
| isolation and characterization of rhamnogalacturonan oligomers, liberated during degradation of pectic hairy regions by rhamnogalacturonase. | digests of modified hairy regions of apple pectin (mhr) obtained after degradation by rhamnogalacturonase (rgase) were analyzed for oligomer composition using high-performance anion-exchange chromatography and pulsed amperometric detection. a series of oligomers which appear to be characteristic of rgase degradation could be recognized. these oligomers were isolated on a preparative scale by size-exclusion chromatography and preparative anion-exchange chromatography and analyzed for sugar compos ... | 1994 | 8194077 |
| nucleotide sequences of apple stem pitting virus and of the coat protein gene of a similar virus from pear associated with vein yellows disease and their relationship with potex- and carlaviruses. | the nucleotide sequence (9306 nucleotides) of cdna clones of apple stem pitting virus (aspv) obtained from a double-stranded rna template, extracted from diseased plant tissue, was determined. the genome is composed of five open reading frames (orfs) encoding putative proteins with m(r)s of 247083, 25147, 12832, 7429 and 43712, and has a poly(a) tail. using two oligonucleotides designed from the aspv sequence information a 1598 bp fragment from near the 3' terminus of the viral rna, containing t ... | 1994 | 8021584 |
| production of single-cell oil from prickly-pear juice fermentation by cryptococcus curvatus grown in batch culture. | the biomass of cryptococcus curvatus, an oleaginous yeast, reached 11 g/l and accumulated 46% (w/w) lipid when grown for 35 h in batch culture on diluted (25%) prickly-pear juice. the c:n ratio of the juice was about 50 g/g. the efficiency of substrate conversion was 0.48 g/g for biomass and 0.22 g/g for lipids. the extracted lipids were mainly oleic (18:1) and palmitic (16:0) acids and the quality of pipid approached that of palm oil. | 1994 | 24421128 |
| chlorine dioxide for reduction of postharvest pathogen inoculum during handling of tree fruits. | alternatives to hypochlorous acid and fungicides are needed for treatment of fruit and fruit-handling facilities. chlorine dioxide was evaluated and found effective against common postharvest decay fungi and against filamentous fungi occurring on fruit packinghouse surfaces. in vitro tests with conidial or sporangiospore suspensions of botrytis cinerea, penicillium expansum, mucor piriformis, and cryptosporiopsis perennans demonstrated >99% spore mortality within 1 min when the fungi were expose ... | 1994 | 16349354 |
| the transcription factor bsap (nf-hb) is essential for immunoglobulin germ-line epsilon transcription. | treatment of murine splenic b lymphocytes and certain b-lineage cell lines with mitogen (lps) and the lymphokine il-4 has been shown to induce expression of germ-line epsilon transcripts (l epsilon transcripts) and class switching to the c epsilon gene. three protein complexes, one of which (complex 3) is constitutively expressed, have been shown to bind to a 179-base pair lps/il-4-responsive l epsilon promoter (rothman, p., s. c. li, b. gorham, l. glimcher, f. w. alt, and m. boothby. 1991. mol. ... | 1994 | 8144891 |
| hair cells of different shapes and their placement along the frog crista ampullaris. | the list of distinguishing morphological features of hair cells includes: type i and type ii afferent innervation, and length, shapes and arrangements of stereo- and kinocilia. we now add to this list the shapes of the hair cells themselves and their placement within the mechanosensory organ, in this case the semicircular canal. although hair cells of the crista ampullaris of the frog are only of type ii they may now be further classified into three sub-groups according to shape: club-, cigar- a ... | 1994 | 8157499 |
| cytoplasmic forms of fission yeast casein kinase-1 associate primarily with the particulate fraction of the cell. | two novel casein kinase-1 homologs, cki1+ and cki2+, have been isolated from schizosaccharomyces pombe and characterized. both genes reside on chromosome ii and encode approximately 50-kda proteins that are related structurally and enzymatically to the yck gene products of budding yeast. subcellular fractionation experiments demonstrate that cki1 and cki2 are both cytoplasmic enzymes that do not overlap in subcellular distribution and that probably play distinct roles within the cell. although g ... | 1994 | 8163505 |
| muscle- and pneumatic-powered counterpulsating lvads: a pilot study. | there is a worldwide interest in supporting the failing heart with a skeletal muscle by either wrapping it around the natural heart (dynamic cardiomyoplasty) or by constructing a skeletal muscle ventricle (smv) used for counterpulsation. conventional cardiomyoplasty in many clinics carries an operative mortality rate of 15-20% partly because it requires 6 weeks to train the muscle to contract continually. a flexible, pear-shaped blood pump with an inflatable air chamber was designed and made aro ... | 1994 | 8185491 |
| prickly pear (opuntia sp.) pectin alters hepatic cholesterol metabolism without affecting cholesterol absorption in guinea pigs fed a hypercholesterolemic diet. | prickly pear pectin intake decreases plasma ldl concentrations by increasing hepatic apolipoprotein b/e receptor expression in guinea pigs fed a hypercholesterolemic diet. to investigate whether prickly pear pectin has an effect on cholesterol absorption and on enzymes responsible for hepatic cholesterol homeostasis, guinea pigs were fed one of three semipurified diets, each containing 15 g lard/100 g diet: 1) the lard-basal diet with no added cholesterol or prickly pear pectin (lb diet); 2) the ... | 1994 | 8207539 |
| maturation of somatostatin immunoreactivity in the pigeon retina: morphological characterization and quantitative analysis. | in addition to a modulatory function, somatostatin (ss) is likely to exert a morphogenetic and/or trophic role in the developing nervous system. in this study, a mouse monoclonal antibody directed to ss was used to investigate the posthatching development of ss-immunoreactivity (ss-ir) in the pigeon retina to provide a basis for a better understanding of the role of this peptide in retinal maturation. in the adult, ss-ir was observed in amacrine cells located in the inner nuclear layer (inl) of ... | 1994 | 7912104 |
| immunohistochemical localization of neuropeptide y and somatostatin in human fetal retina. | the localization of neuropeptide y and somatostatin in the retina of six prenatal human specimens was determined by the utilization of light microscopic immunoperoxidase and immunofluorescence methods. the age of the prenatal fetuses ranged from 15 to 40 weeks of gestation. at 15 weeks, round or pear-shaped neuropeptide y-immunopositive cells were observed in the inner nuclear layer and somatostatin immunoreactivity was only detected in the ganglion cell layer. positive neuropeptide y ganglion c ... | 1994 | 7936198 |
