background: depression and smoking decrease health status in chronic obstructive pulmonary disease (copd), but the combined effect of the two factors is unknown. this study aimed to assess the interactive effects of depression and smoking on the severity of patients with copd. methods: a prospective cohort study including 2,268 patients with copd was conducted in seven rural communities from ma...

By far, only tigecycline, colistin, and some aminoglycosides still show favorable in vitro activities against carbapenem-resistant Enterobacteriaceae. However, rapid emergence of resistance often occurs during long-term treatment in clinic, challenging these last resort antimicrobials. In this study, we measured mutant prevention concentration (MPC) and mutant selection window (MSW) of tigecycl...

The present study examines the effect of combinations of gabapentin (Neurontin) and a selective neurokinin (NK)(1) receptor antagonist, 1-(1H-indol-3-ylmethyl)-1-methyl-2-oxo-2-[(1-phenylethyl)amino]ethyl]-2-benzofuranylmethyl ester (CI-1021), in two models of neuropathic pain. Dose responses to both gabapentin and CI-1021 were performed against static allodynia induced in the streptozocin and ...

The purpose of the present study was to evaluate anti-nociceptive effects of morphine, tramadol, meloxicam and their combinations in rats. Seventy male Wistar rats were divided into seven equal groups and randomly assigned to receive intraperitoneal saline (S) (control group, 1.0 mL kg-1), morphine (MO) (4.0 mg kg-1), tramadol (TR) (12.5 mg kg-1), meloxicam (ML)...

Intercellular adhesion molecule 1 (ICAM-1) is an important molecule in promotion of polymorphonuclear neutrophil transendothelial migration during inflammation. Coincident with many inflammatory diseases is tissue hypoxia. Thus we hypothesized that combinations of hypoxia and inflammatory stimuli may differentially regulate expression of endothelial ICAM-1. Human endothelial cells were exposed ...

A family of genes has been identified that encodes subunits of nicotinic acetylcholine receptors (nAChRs) and is expressed in the nervous system. Functional neuronal nAChRs can be expressed in Xenopus oocytes by injection of RNA encoding 1 of 2 different &subunits (/32,84) in pairwise combination with RNA encoding 1 of 3 different a-subunits (a2, (~3, a4). We examined the sensitivity of these 6...

Association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. This study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. This investigation was performed using 77 barley genotypes and AFLP markers. In phenotypic evaluation, reaction of seedlings to powdery mild...

Seventy seven adult large mixed breed dogs of either sex were included in this study. The animals were randomly divided into four groups and received the following drug combinations intramuscularly: Group 1 xylazine (0.5 mg/kg) and acepromazine (0.05 mg/kg), Group 2 xylazine (0.8 mg/kg) and acepromazine (0.03 mg/kg), Group 3 xylazine (0.3 mg/kg) and acepromazine (0.08 mg/kg) and Group 4 xylazin...
