Glycogen and its products of metabolism are considered to be the most important and direct source of nutrient for the early conceptus. The premenstrual biopsies were taken from 100 women with primary infertility whose male partners had normal semenograms. The biopsies were then subjected to Haematoxylin and Eosin (H & E) and Periodic Acid Schiff (PAS) staining with and without diastase to study...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
The teratogenic mechanism(s) of valproate (VPA) have been suggested to arise through inhibition of proliferation coupled with differentiation at a mid-G1 phase restriction point in the cell cycle. As protein kinase C (PKC) plays a pivotal role in cell proliferation and differentiation, the effect of inhibitors specific for the catalytic and regulatory domains on transit through the G1 phase of ...
BACKGROUND Angiogenesis occurs by at least three mechanisms: sprouting, intussusception and elongation. Studies to date have failed to identify the mechanisms or timing of endometrial angiogenesis during the menstrual cycle. The aim of this study was to determine if vessel elongation plays a role in human endometrial angiogenesis. METHODS Forty-nine full thickness endometrial sections from 27...
PURPOSE Vascular degeneration and the ensuing abnormal vascular proliferation are central to proliferative retinopathies. Given the metabolic discordance associated with these diseases, the authors explored the role of ghrelin and its growth hormone secretagogue receptor 1a (GHSR-1a) in proliferative retinopathy. METHODS In a rat model of oxygen-induced retinopathy (OIR), the contribution of ...
The Present study attempts to determine the relationship between proliferation and inhibition of apoptosis in normal endometrium hyperplasia, using monoclonal antibodies against marker, Ki-67 anti-apoptotic protein, Bcl-2 expression B-cell lymphoma 2 (Bcl – 2) Ki 67 cyclical proliferative secretory phase. includes Bcl endometrial hyperplasia.
BACKGROUND Epithelial mesenchymal transition (EMT) is involved in the pathogenesis of adenomyosis, and Notch signaling is crucial to EMT. The objective of this study was to explore Notch1/Numb/Snail signaling in adenomyosis. METHODS The expression levels of the members of the Notch1/Numb/Snail signaling cascade in normal endometria (proliferative phase: n = 15; secretory phase: n = 15; postme...
Macrophages have long been known to play a major role in the pathogenesis of proliferative vitreoretinal disorders. Using the monoclonal antibodies EBM11 (pan macrophage), 27E10 (early inflammatory stage marker), and RM3/1 (healing phase marker), different subpopulations of macrophages were differentiated in surgically removed membranes from patients with macular pucker (n = 6), proliferative v...
BACKGROUND: Menstruation is a phenomenon unique to females and nearly universal experience in women's lives and is poorly understood. It is characterized by co-ordinate sequence of hormonal changes but the changes that occur in the distribution of hematological parameters, biochemical parameters have not been clearly established. AIMS: To compare Erythrocyte Sedimentation Rate (ESR), Serum tota...
