(Academic Press Inc., 1997)Hyperthyroidism enhances the prooxidant activity of the liver by elevating superoxide radical and/or hydrogen peroxide generation in microsomal, mitochondrial, and peroxisomal fractions, with an increased respiratory burst ...
-
(1998)Indirect evidence has suggested that K-Cl cotransport in human and sheep erythrocytes is activated physiologically by a serine-threonine phosphatase. It is activated experimentally by H2O2 and by staurosporine, a kinase ...
-
(1998)Human chorionic gonadotropin is a glycoprotein hormone that, like LH, stimulates steroidogenesis in gonadal cells. Using a desialylation process, 95 per cent of the sialic acid residues from an intact standard hCG molecule ...
-
(Springer New York LLC, 1998)The influence of hydroxamic acids (Hx), plant secondary metabolites associated with aphid resistance in wheat, on the host acceptance and suitability of the aphid Sitobion avenae to the cereal aphid parasitoid Aphidias ...
-
(Kluwer Academic Publishers, 1998)Hydroxamic acids are secondary metabolites typical of Poaceae that play a role in cereal resistance against pests and pathogens. The content of the hydroxamic acid aglucones DIBOA (2,4-dihydroxy-1,4-benzoxazin-3-one) and ...
-
(Mosby Inc., 1998)OBJECTIVE: The purpose of this study was to determine whether there are demonstrable alterations in uterine artery blood flow in pregnant women with mullerian duct anomaly. STUDY DESIGN: Flow velocity waveforms obtained ...
-
(1997)The human vas deferens (VD) is often considered simply as a conduit to transfer mature sperm from the epididymis to the ejaculatory duct. The cells that make up the epithelium of the VD, however, exhibit many characteristics ...
-
(1998)Concepts about nutrient intake requirements and recommendations have emerged from a period of relative consensus about concepts and goals to one of vertiginous shifts of paradigms and a proliferation of agendas, often ...
-
(Guilford Publications, 1998)This article describes what happened with the participants and the group as a whole in an analytical group psychotherapy session. Our aim is to reveal how the particular session was run. We describe a period of resistance ...
-
(1998)For functional recovery after spinal cord injury, regenerating fibres need to grow and to reform appropriate connections with their targets. The isolated central nervous system of neonatal opossums aged 1-9 days has been ...
-
(Academic Press, 1998)Actualistic studies of small mammal taphonomy usually describe interspecific bone patterns of contemporary agents of bone deposition. These studies assume that each agent produces one specific bone pattern. Here we examine ...
-
(1998)Thapsigargin (TG), a plant-derived sesquiterpene lactone, inhibits several isoforms of both the sarcoplasmic and endoplasmic reticulum Ca 2+- ATPases. Thus, intracellular Ca 2+ stores found in the endoplasmic reticulum can ...
-
(Academic Press Inc., 1998)There is increasing evidence that the different polymers that constitute the cytoskeleton are interconnected to form a three-dimensional network. The macromolecular interaction patterns that stabilize this network and its ...
-
(1998)Prenatal malnutrition results in increased concentration and release of central noradrenaline, a neurotransmitter that is an important regulator of normal regressive events such as axonal pruning and synaptic elimination. ...
-
(American Lung Association, 1998)The purpose of the study was to validate the criteria used in the guidelines of the American Thoracic Society (ATS) for severe community- acquired pneumonia (CAP). Severe pneumonia was defined as admission to the intensive ...
-
(1998)We have conducted flow cytometric studies of two subsets of lymphocyte markers in groups of migraineurs during (n = 12; group B) and outside (n = 10; group C) of a migraine without aura attack (total n = 22; group A), ...
-
(1998)Penicillium purpurogenum was mutated with u.v. light to increase xylanase production. The best mutant, UV-64, was treated with N-methyl-N'-nitro-N-nitrosoguanidine and a second generation of mutants was obtained (NG-188 ...
-
(Oxford University Press, 1998)Flow cytometry analysis of luteal cells revealed that an important proportion of these cells are leukocytes. The percentage of leukocytes was higher in the early (42 ± 4) and late (35 ± 3) luteal phases than in the mid-luteal ...
-
(1998)Genetic markers and total intelligence quotient (IQ) assessed by WISC (Wechsler Intelligence Scale for Children) were studied in children of both sexes from Santiago, Chile. Heterozygous boys for phosphoglucomutase 1 (PGM) ...
-
(1998)To evaluate the effect of nitric oxide (NO·) in human corpus luteum (CL) function, we investigated the expression and the presence of NO· synthase (NOS) in the human CL and the action of NO· on the in vitro luteal ...
