BACKGROUND The economic stress hypothesis (ESH) predicts decreases in the sex ratio at birth (SRB) following economic decline. However, as many factors influence the SRB, this hypothesis is difficult to test empirically. Thus, researchers make use of quasi-experiments such as German reunification: The economy in East, but not in West Germany, underwent a rapid decline in 1991. A co-occurrence o...

objective: envenomation by heamotoxic snakes constituted a critical health occurrence in the world. bleeding is the most sever consequence following snake bite with viperid and crothalid snakes. it is believed that the degradation of vascular membrane caused hemorrhage; in contrast, some suggested that direct cytotoxicity has role in endothelial cell disturbances. this study was to evaluate the...

We study the existence of SRB measures and their properties for a class of infinite dimensional dynamical systems. We show several results including (i) if the system has a partially hyperbolic attractor with nontrivial finite dimensional unstable directions, then it has at least one SRB measure; (ii) if the attractor is uniformly hyperbolic, the system is topological mixing, and the splitting ...

Background & Objective: In recent decades, South Korea is the only country to show a unique Sex Ratio at Birth (SRB) transition. After drastic ups and downs, the transition epidemic appears to be over. Sex selective abortion was widely thought to be the main contributor to this trend. Despite the enormous focus given to Korea’s uniquely fluctuating SRB statistics, and in particular the factors ...

Anaerobic mineralization processes were studied over a period of 40 d in an organic-rich sediment amended with labile organic matter (fish food pellets). Although measured sulfate reduction rates (SRR) were hlgh (up to -2400 nmol cm-3 d-l), a coexistence between sulfate-reducing bacteria (SRB) and methane-producing bacteria (MPB) was evident. Methane production rates (MPR) of the same order of ...

Many large scale research programs with massive data requirements (e.g. the Particle Physics Data Grid, the Biomedical Informatics Research Network) use SRB to manage research data collections. Despite this broad adoption, the potential of SRB and Data Grids is not fully utilized by the general research community. The reason for this under utilisation comes in part from the complexity of the Da...

BACKGROUND Excessive production of free radicals has been implicated in many diseases including cancer. They are highly reactive and bring about oxidation of biomolecules i.e., proteins, lipids and nucleic acids which are associated with many degenerative diseases. Natural products acting as antioxidants have ability to neutralize free radicals and their actions and hence they mitigate their ha...

     The chloroform soluble fractions of ethanolic extracts of five Inula belonging to the Compositae family were evaluated for cytotoxic activity against five different cell lines including CACO2 (human colon adenocarcinoma), MCF7 (human breast adenocarcinoma), HEPG2 (human hepatocellular carcinoma), VERO (green African monkey kidney) and WEHI164 (balb c mouse fibrosarcoma). Cytotoxic...

abstractferulago angulata boiss. known in iran as chavir, has some bioactive compounds having antioxidant activity. because of its antioxidant activities, it sounded chavir extract can be a good candidate for finding chemopreventive agents having inductive apoptosis properties on cancer cells. in this study, the cytotoxic effects and proapoptotic activities of chavir’s leaf and flower extracts ...

Oral administration of Saiko-ka-Ryukotsu-Borei-To (SRB), a traditional Chinese formulation, dose dependently inhibited intimal thickening in carotid artery injured by balloon endothelial denudation in cholesterol-fed rats. SRB also inhibited vascular smooth muscle cell (VSMC) proliferation, which is assessed by counting the VSMCs immunoreactive with antiproliferating cell nuclear antigen (PCNA)...
