Hepatic insulin resistance has been attributed to both increased endoplasmic reticulum (ER) stress and accumulation of intracellular lipids, specifically diacylglycerol (DAG). The ER stress response protein, X-box-binding protein-1 (XBP1), was recently shown to regulate hepatic lipogenesis, suggesting that hepatic insulin resistance in models of ER stress may result from defective lipid storage...

This paper presents an experimental study on the pullout resistance of a newly improved reinforcement. The applied reinforcement was smooth steel strip with transverse members used to improve pullout-resistance problems and bearing were evaluated using results large-scale tests. evaluation result confirmed that about 33–66% total resistance, it had evenly distributed friction resistance. bond c...

Rubber trees are economically important tropical tree species and the major source of natural rubber, which is an essential industrial material. This tropical perennial tree is susceptible to cold stress and other abiotic stresses, especially in the marginal northern tropics. Recent years, the genome sequencing and RNA-seq projects produced huge amount of sequence data, which greatly facilitate...

Crop yield has been greatly enhanced during the last century. However, most elite cultivars are adapted to temperate climates and are not well suited to more stressful conditions. In the context of climate change, stress resistance is a major concern. To overcome these difficulties, scientists may help breeders by providing genetic markers associated with stress resistance. However, multistress...

background: s-methyl cysteine (smc) is a hydrophilic cysteine-containing compound naturally found in garlic and onion. the purpose of the present study was to investigate the protective effect of smc on oxidative stress, inflammation and insulin resistance in an experiment of metabolic syndrome. methods: male wistar rats were divided into five groups (6 rats in each group), namely; control, con...

Resistance to environmental stress is one of the most important forces molding the distribution and abundance of species. We investigated the evolution of desiccation stress resistance using 20 outbred Drosophila melanogaster populations directly selected in the laboratory for adult desiccation resistance (D), postponed senescence (O), and their respective controls (C and B). Both aging and des...

We trace the evolutionary correlation between stress resistance and longevity in populations of Drosophila melanogaster selected for stress resistance over many generations. Females selected for desiccation resistance and both females and males selected for increasing starvation resistance initially show concurrent increases in longevity, but then begin to decrease in longevity, even as stress ...

OBJECTIVE Systemic oxidative stress causes insulin resistance in rodents. We tested the hypothesis that oxidative stress and insulin resistance are associated in humans. RESEARCH DESIGN AND METHODS We used cross-sectional data from 2,002 nondiabetic subjects of the community-based Framingham Offspring Study. We measured insulin resistance with the homeostasis model and defined categorical ins...
