OBJECTIVE To investigate the relationships between social isolation, health literacy, and all-cause mortality, and the modifying effect of social isolation on the latter relationship. METHODS Data were from 7731 adults aged ≥50 years participating in Wave 2 (2004/2005) of the English Longitudinal Study of Ageing. Social isolation was defined according to marital/cohabiting status and contact ...

Design of Global Positioning System (GPS) receiver with a low noise amplifier (LNA) in the front end remains a major design requirement for the success of modern day navigation and communication system. Any LNA is expected to meet the requirements like its ability to add the least amount of noise while providing sufficient gain, perfect input and output matching, and high linearity. However, mo...

Because of the high energy consumption for fermentor cooling, the isolation of thermo-tolerant Acetobacter strains for vinegar production has a high priority. The aims of this study were the isolation and identification of a high ethanol-thermo-tolerant Acetobacter spp. from grapes as well as the optimization of conditions for increasing the acetic acid production. The grape e...

Background: The purification of Schwann cells has proven to be a difficult process, with most methods requiring the use of special equipment. However, obtaining a sufficient number and high purity of Schwann cells is an integral aspect in their use for clinical application. Therefore, the aim of this study was to establish a simple and effective protocol for the isolation and purification of Sc...

rotaviruses group a are the major cause of diarrhea in calves under one month and every year causes enormous economic losses. serological and molecular techniques can be used for rapid detection of rotaviruses but virus isolation requires specific methods of cell culture and suitable cell lines. in this study, 41 samples were collected from diarrheal calves up to the age of one month, from indu...

this study has been carried out with the objective of isolation and identification of agent(s) of pasteurella pneumonia in sheep and goat in iran using bacteriological and biochemical assays to be identified in the pursuant researches to be used in pasteurellosis vaccine production. to accomplish this objective, samples were gathered from areas suspicious to pasteurellosis infection and industr...

a highly efficient, simple and clean solvent-free protocol for the synthesis of polyhydroquinolines is described. the one-pot multi-component condensation reaction between arylaldehydes, dimedone (5,5-dimethylcyclohexane-1,3-dione), β-ketoesters and ammonium acetate in the presence of catalytic amount of (2.5 mol%) melamine trisulfonic acid (mtsa) as a recyclable, green and attractive sulfonic ...
