A New Insight into the Role of CART in Cocaine Reward: Involvement of CaMKII and Inhibitory G-Protein Coupled Receptor Signaling.

Cocaine- and amphetamine-regulated transcript (CART) peptides are neuropeptides that are expressed in brain regions associated with reward, such as the nucleus accumbens (NAc), and play a role in cocaine reward. Injection of CART into the NAc can inhibit the behavioral effects of cocaine, and injecting CART into the ventral tegmental area (VTA) reduces cocaine-seeking behavior. However, the exact mechanism of these effects is not clear.

Beneficial Soil Bacterium OS261 Augments Salt Tolerance and Promotes Red Pepper Plant Growth.

Soil salinity, being a part of natural ecosystems, is an increasing problem in agricultural soils throughout the world. OS261 has already been proved to be an effective bio-inoculant for enhancing cold stress tolerance in plants, however, its effect on salt stress tolerance is unknown. The main aim of the present study was to elucidate OS261 mediated salt stress tolerance in red pepper.

Control of Wilt and Rot Pathogens of Tomato by Antagonistic Pink Pigmented Facultative Methylotrophic and spp.

The studies on the biocontrol potential of pink pigmented facultative methylotrophic (PPFM) bacteria other than the genus are scarce. In the present study, we report three facultative methylotrophic isolates; PPO-1, PPT-1, and PPB-1, respectively, identified as , and by 16S rRNA gene sequence analysis. Hemolytic activity was tested to investigate the potential pathogenicity of isolates to plants and humans, the results indicates that the isolates PPO-1, PPT-1, and PPB-1 are not pathogenic strains.

Mycorrhizal Symbiotic Efficiency on C3 and C4 Plants under Salinity Stress - A Meta-Analysis.

A wide range of C3 and C4 plant species could acclimatize and grow under the impact of salinity stress. Symbiotic relationship between plant roots and arbuscular mycorrhizal fungi (AMF) are widespread and are well known to ameliorate the influence of salinity stress on agro-ecosystem. In the present study, we sought to understand the phenomenon of variability on AMF symbiotic relationship on saline stress amelioration in C3 and C4 plants.

The PPARγ agonist protects cardiomyocytes from oxidative stress and apoptosis via thioredoxin overexpression.

Oxidative stress has been implicated in the pathogenesis of various cardiovascular diseases, including ischemic heart disease and heart failure. The peroxisome proliferator-activated receptor gamma (PPARγ) agonist improves insulin sensitivity and limits tissue inflammation and cellular apoptosis, but there are few data on the relationship between the PPARγ agonist, rosiglitazone (RSG), and the thioredoxin (TRx) system in oxidatively stressed cardiomyocytes (CMCs). Here we provide evidence that the PPARγ agonist RSG protects rat CMCs from hydrogen peroxide (H2O2)-induced apoptosis by TRx overexpression.
