The oocytes found within the primordial follicles of mammalian ovaries remain quiescent for months to years until they receive the appropriate signals to undergo the primordial to primary follicle transition and initiate folliculogenesis. The molecular mechanisms and extracellular signaling factors that regulate this process remain to be fully elucidated.… (More)
Erythropoietin receptor (EpoR) has been reported to be overexpressed in tumours and has raised safety concerns regarding the use of erythropoiesis-stimulating agents (ESAs) to treat anaemia in cancer patients. To investigate the potential for EpoR to be overexpressed in tumours, we have evaluated human tumours for amplification of the EPOR locus, levels of… (More)
BACKGROUND Later Pleistocene human evolution in East Asia remains poorly understood owing to a scarcity of well described, reliably classified and accurately dated fossils. Southwest China has been identified from genetic research as a hotspot of human diversity, containing ancient mtDNA and Y-DNA lineages, and has yielded a number of human remains thought… (More)
A set of 5 anti-dioxin monoclonal antibodies (mAbs), named DD-1, DD-3, DD-4, DD-5 and DD-6, have been isolated. In order to evaluate the ability of these mAbs to recognize various kinds of polychlorinated dibenzodioxins and dibenzofurans, a competition enzyme-linked immunosorbtion assay (ELISA) was developed. All 5 antibodies recognize tetrachloro- and… (More)
1495 Absence of enzymatic hydrogen-carrying systems is a factor in aerobic glycolysis of malignant tissue. Kinds of causes, predictability, and teleology are viewed by a practicing biologist. The very high radiation flux densities of optical masers point to important biomedical applications.
