Novel mutation in gene in a family diagnosed with 3M syndrome.

This study evaluates a family with two siblings having severe growth retardation and facial dysmorphism, born to consanguineous normal healthy parents. Affymetrix CytoScan 750K microarray showed a 34-Mb pericentric homozygous region on chromosome 6 for both siblings. was one of the 141 genes present in this region.

Attenuation of isoproterenol-induced cardiotoxicity in rats by Narirutin rich fraction from grape fruit.

Background: Oxidative stress is one of the major mechanism involved in pathogenesis of myocardial infarction. Use of natural products as therapeutic approach for ischemic myocardial injury is gaining attention worldwide.

Purpose: This study was designed to investigate efficacy of Narirutin rich fraction (NRF), obtained from grape fruit peel, in the treatment of isoproterenol induced myocardial infarction in rats.

IFN-γ promotes transendothelial migration of CD4 T cells across the blood-brain barrier.

Transendothelial migration (TEM) of Th1 and Th17 cells across the blood-brain barrier (BBB) has a critical role in the development of experimental autoimmune encephalomyelitis (EAE). How cytokines produced by inflammatory Th1 and Th17 cells damage the endothelial BBB and promote transendothelial migration of immune cells into the central nervous system (CNS) during autoimmunity is not understood. We therefore investigated the effect of various cytokines on brain endothelial cells.

Evaluation of vascular endothelial growth factors A, C and D as indicators of lymphangiogenesis and angiogenesis in invasive and non-invasive urothelial carcinoma bladder.

Objective: To study the immunohistochemical expression of vascular endothelial growth factors in urothelial tumours of bladder and its possible association with tumour characteristics and microvessel density.

Methods: The cross-sectional descriptive study was conducted at the Histopathology Department of the Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from July 2011 to December 2012, and comprised cases of non-invasive and invasive urothelial tumours of the bladder. The microvessel density and expression of vascular endothelial growth factors A, C, D were evaluated by immunohistochemistry.

An appraisal of biological responses and network of environmental interactions in non-mining and mining impacted coastal waters.

The coastal waters of Goa and Ratnagiri lying on the West coast of India are influenced by terrestrial influx. However, Goa is influenced anthropogenically by iron-ore mining, while Ratnagiri is influenced by deposition of heavy minerals containing iron brought from the hinterlands. We hypothesize that there could be a shift in biological response along with changes in network of interactions between environmental and biological variables in these mining and non-mining impacted regions, lying 160 nmi apart.

Study of lead exposure to children residing near a lead-zinc mine.

This lead exposure study was conducted in a total of 452 school children in the age group of 9-14 years. Two hundred and ninety-eight exposed children came from the villages situated within a 2.5 km radius of the lead-zinc mine whereas the comparative group children were selected from the villages at least 10 km away from mine.
