Blood Pressure Lowering And Vasomodulator Effects Of Piperine, Syed Intasar Husain Taqvi, Abdul Jabbar Shah, Anwar Gilani Nov 2008

Blood Pressure Lowering And Vasomodulator Effects Of Piperine, Syed Intasar Husain Taqvi, Abdul Jabbar Shah, Anwar Gilani

Department of Biological & Biomedical Sciences

This study was aimed to explore underlying mechanism(s) of cardiovascular effects of piperine. Intravenous administration of piperine caused a dose-dependent (1 to 10 mg/kg) decrease in mean arterial pressure (MAP) in normotensive anesthetized rats, the next higher dose (30 mg/kg) did not cause any further change in MAP. The fall in blood pressure (BP) was followed by small increase in MAP after each dose. In Langendorrf's rabbit heart preparation, piperine caused partial inhibition and verapamil caused complete inhibition of force and rate of ventricular contractions and coronary flow. In rabbit aortic rings, piperine inhibited high K(+) (80 mM) precontractions and …

A range of proteins has been recognized as mediators/hypothetical receptors for hepatitis B virus (HBV), but the results are conflicting and inconclusive especially regarding their biological significance. This study was aimed at identifying a novel HBV-interacting protein which would provide a better understanding of its transport in blood, attachment, fusion and entry into hepatocytes. Serum samples positive for HBV confirmed by PCR were subjected to ammonium sulfate fractionations at 50, 75, 100%, saturation. PCR of each fraction demonstrated amplification of HBV in 100% fraction. Protein analysis by SDS PAGE of fractions showed one band of approximately 69 kDa protein, in …


The Cradle Of The Deltaf508 Mutation, Danish Saleheen, Philippe M Frossard Oct 2008

The Cradle Of The Deltaf508 Mutation, Danish Saleheen, Philippe M Frossard

Department of Biological & Biomedical Sciences

Cystic fibrosis (CF) is the most common autosomal recessive disorder caused due to mutation/s in the CFTR gene. The most common mutation in CFTR worldwide is deltaF508 and cystic fibrosis genetic analysis consortium revealed that this mutation is responsible for approximately 66% of all CF chromosomes in the world. Studies looking at the DNA polymorphic haplotypes created by CF linked markers suggest that deltaF508 has a single origin as this mutation has been found associated exclusively with one marker haplotype. Despite a high prevalence of this mutation in CF patients in northern parts of Europe, findings suggest that this mutation …
