The human fetal adrenal produces cortisol but no detectable aldosterone throughout the second trimester
BACKGROUND Human fetal adrenal glands are highly active and, with the placenta, regulate circulating progesterone, estrogen and corticosteroids in the fetus. At birth the adrenals are essential for neonate salt retention through secretion of aldosterone, while adequate glucocorticoids are required to prevent adrenal insufficiency. The objective of this study was to carry out the first comprehen...
متن کاملAntioxidant defences in the microaerophilic protozoan Trichomonas vaginalis: comparison of metronidazole-resistant and sensitive strains.
The sensitivity of the microaerophilic protozoan Trichomonas vaginalis to oxygen and products of its reduction, and the antioxidant defences employed by this organism, were investigated. Studies revealed that this amitochondrial flagellate is sensitive to oxygen tensions above those experienced in situ in the vagina (i.e. > 60 microM) and that metronidazole-resistant strains (CDC 85 and IR78) w...
متن کاملThe bovine CD1 family contains group 1 CD1 proteins, but no functional CD1d.
The CD1 family of proteins presents lipid Ags to T cells. Human CD1a, CD1b, and CD1c have been shown in humans to present mycobacterial lipid Ags. Cattle, like humans, are a natural host of several mycobacterial pathogens. In this study, we describe the CD1 family of genes in cattle (Bos taurus) and provide evidence that B. taurus expresses CD1a, CD1e, and multiple CD1b molecules, but no CD1c a...
متن کاملMicroembolism Induces Anhedonia but No Detectable Changes in White Matter Integrity in Aged Rats
Microvascular disease leads to alterations of cerebral vasculature including the formation of microembolic (ME) strokes. Though ME are associated with changes in mood and the severity and progression of cognitive decline, the effect of ME strokes on cerebral microstructure and its relationship to behavioral endpoints is unknown. Here, we used adult and aged male rats to test the hypotheses that...
متن کاملUnusual behavior of the cytoplasmic transcript of hsr omega: an abundant, stress-inducible RNA that is translated but yields no detectable protein product
Although a major site of transcription in heat shock, the Drosophila hsr omega gene does not encode any known heat shock proteins. Instead, studies of the hsr omega transcripts suggest that the RNA molecules, rather than encoded proteins, are the active products of this gene. The cytoplasmic RNA, omega 3, is spliced and polyadenylated and yet has only very small open reading frames (ORFs), and ...
