We studied the effect of enteral administration of GABA on the gastric mucosa in male Wistar rats (n=47) with modeled metabolic stress (food deprivation for 9 days with free access to water). The relative weights of the adrenal glands and thymus were determined, and histological examination of the stomach was performed. In control rats, modeling the metabolic stress was accompanied by the development of erosive damage to the gastric mucosa related to blood supply disturbances. Administration of GABA prevented erosions and exhibited a pronounced gastroprotective effect. Thus, administration of GABA can be a promising method for the prevention and treatment of erosive gastric lesions associated with metabolic stress.

Stress responsiveness in a wild primate predicts survival across an extreme El Niño drought.

We know more about the costs of chronic stress than the benefits of the acute stress response-an adaptive response that buffers organisms from life-threatening challenges. As yet, no primate study has empirically identified how the stress response adaptively affects evolutionary fitness. Here, we take advantage of a natural experiment-an El Niño drought-that produced unprecedented mortality for wild white-faced capuchins.

A key response to acute stress is the increased brain synthesis of the neurosteroid allopregnanolone (AP). Although the rate-limiting step of this reaction is catalyzed by 5α-reductase (5αR), the role of its two primary isoenzymes, 5αR1 and 5αR2, in stress reactivity remains unclear. Here, we found that acute stress led to increased levels of 5αR2, but not 5αR1, in the medial prefrontal cortex (mPFC) of male, but not female, rats.

Background: Ubiquitination and deubiquitination are involved in the progression of human diseases, including acute pneumonia. In this study, we aimed to explore the functions of ubiquitin-specific peptidase 9X-linked (USP9X) in lipopolysaccharide (LPS)-treated WI-38 cells. Methods: WI-38 cells were treated with LPS to induce the cellular damage and inflammation.

Anthropic activities such as industries, agriculture and mining has generated public concern for its numerous irregular disposals of its waste, the incorrect deposition of heavy metals such as nickel (Ni) has caused the degradation and contamination of groundwater and water. Studies that point out cheap and efficient solutions have been an obstacle to the advancement of solutions for degraded area recovery programs. For this, a vegetable home experiment was developed, with an entirely randomized design with 5 treatments being a control (no metal) and 4 nickel concentrations (200 μM/L; 400 μM/L; 600 μM/L and 800 μM/L) with 6 repetitions.

Marine heatwaves are increasing in intensity and frequency however, responses and survival of reef corals vary geographically. Geographical differences in thermal tolerance may be in part a consequence of intraspecific diversity, where high-diversity localities are more likely to support heat-tolerant alleles that promote survival through thermal stress. Here, we assessed geographical patterns of intraspecific genetic diversity in the ubiquitous coral Pocillopora damicornis species complex using 428 sequences of the Internal Transcribed Spacer 2 (ITS2) region across 44 sites in the Pacific and Indian Oceans.
