Osmotically acting amino acids can be cytoprotective following injury. As threonine (THR) induces osmotic cell swelling, our aim was to investigate the potential for THR to induce cellular protection in intestinal epithelial cells and evaluate possible mechanisms of protection. ⋯ This is the first demonstration that THR increases HSP70 and HSP 25 and protects cells from HS. THR's mechanism of protection may involve cytoskeletal stabilization, HSP up-regulation and nuclear translocation, and decreased apoptosis. THR's protection appears to involve both cell-swelling-dependent and -independent processes.

The aim of this study was to examine whether resveratrol might represent a promising therapeutic tool with which to combat adipose tissue chronic inflammation in a model of genetic obesity and to link its anti-inflammatory activity with its effect on body fat reduction. ⋯ The present results provide evidence that fatty acid uptake and lipolysis are metabolic pathways involved in the response of adipose tissue to RSV. This polyphenol modulates plasma cytokine levels partially by reducing macrophage infiltration in adipose tissue and inhibiting NF-κB activity.

Very few reports thus far have clinically elucidated the advantages of a nutrition support team (NST) in the field of liver diseases. The present study retrospectively analyzed whether nutrition therapy for liver cirrhosis (LC), performed by a multidisciplinary team that includes registered dieticians, improves survival rates. ⋯ This study showed that nutritional intervention using a multidisciplinary team during the treatment of LC improves survival rates and quality of life of the patients.

Fatigue can be caused by a deficiency of nutrition or immune function. The goal of this study was to identify the effects of porcine placenta extract (PPE) and its constituents, amino acids (glutamic acid, glycine, arginine, and proline), on protein-energy malnutrition (PEM)-induced fatigue. ⋯ These results demonstrate that PPE and its constituents regulate PEM-induced fatigue through improving levels of immunity and decreasing fatigue-related factors. PPE may be a potential agent for a recovery from fatigue.

Protective effects of trigonelline (TRG) isolated from fenugreek seed were evaluated in isoproterenol (ISO)-induced myocardial dysfunctions in adult rats and a proteomic approach was applied to understand its mechanism of action. ⋯ For the first time, our study revealed the down-regulation of Hsp27 and αB-crystallin and (CaMKII delta) isoform by TRG. As the test compound prevented the ISO-induced myocardial injury, its therapeutic use may further be explored.
