Comparison and Performance Analysis of Unipolar and Bipolar Digitally-Controlled Single-Phase Inverters
Inverter is substantially an interface between DC source like photovoltaic cell and AC networks. There are many doable inverter topologies and switching schemes, and each one will have its own relative benefits and downsides. Efficiency and output current distortion are two necessary factors governing the selection of inverter system. In this paper, two inverter switching strategies are explored. These are ... Read more

Ultrastructural study of the effect of carbon tetrachloride on the pars distalis of the anterior pituitary gland of mice and the possible protective role of ginger
Free radicals and oxidative stress can be induced by a variety of factors, such as carbon tetrachloride (CCl4). Ginger (Zingiber officinale Roscoe, Ginger) has antioxidant, antitumoral, and antihepatotoxic activities. Aim of the work The present study was carried out to assess the possible role of ginger on CCl4- induced toxic effects on the pars distalis. Materials and methods Thirty adult ... Read more

The therapeutic efficacy of olfactory stromal cells in rotenone induced Parkinsonism in adult male albino rats
_Background aims. _ Olfactory stem cells (OSCs) are found in the olfactory mucosa and olfactory bulb and have the capacity to proliferate and differentiate along multiple tissue lineages. Rotenone; widely used insecticide has a neurodegenerative effect on the dopaminergic cells of substantia nigra (SN) of midbrain producing Parkinsonism. The aim of this study is to isolate rat OSCs from olfactory ... Read more

Possible Effect Of Gestational Antioxidants On Pre-eclampsia Associated Coagulopathy
Background: Oxidative stress is blamed in the pathogenesis of pre-eclampsia. However, it is less clear what effect gestational antioxidants would have on pre-eclampsia associated coagulopathy, and on neonatal outcome. Aim of the study: To investigate the effect of antioxidants supplementation on coagulopathy during pre-eclampsia and to evaluate maternal and neonatal outcome. Patients and Methods: The study was performed as a ... Read more
