This study investigated the potential beneficial effects of onion extract on brain ischemia-induced edema and blood-brain barrier (BBB) dysfunction. The possible underlying mechanisms are investigated, especially those linked to the antioxidant effects of the onion extract. ⋯ The results from this study demonstrate that onion extract prevents brain edema, BBB hyperpermeability, and tight junction proteins disruption, possibly through its antioxidant effects in the mouse MCAO model. This study suggests that onion extract may be a beneficial nutrient for the prevention of BBB function during brain ischemia.

Anorexia nervosa (AN) continues to be a refractory disease because of its unknown pathogenesis. The role of adiponectin in AN has not been clarified. Moreover, few reports have described the relations between adiponectin isoforms and AN in the physical and psychological states. Therefore, we measured plasma adiponectin and its isoforms levels in patients with AN to examine their roles in AN. ⋯ Our study indicates that all adiponectin isoforms should be evaluated in patients with AN in addition to total adiponectin. The decreased %HMW and the increased %LMW that were correlated with the body mass index and some components of psychopathology in our patients may indicate a complex role of adiponectin isoforms in maintaining energy homeostasis and emotion during extreme malnourishment.

Chronic obstructive pulmonary disease (COPD) is a complex chronic inflammatory disease involving oxidative stress as well as a wide variety of cells activated from smoking cigarettes. There have been disappointingly few therapeutic advances in drug therapy for COPD. Plant polyphenols have been the topic of much research regarding their antioxidant activities and antiinflammatory and immunomodulatory effects. In the present study, we ask whether apple polyphenol provides protection against cigarette smoke (CS)-induced acute lung injury. ⋯ Taken together, APP may be a potential dietary nutrient supplement agent to improve quality of life of COPD patients by inhibiting CS-exposed acute lung injury via P38 MAPK signaling pathway.

Poor oral status, represented by partial/complete tooth loss, may lead to changes in food choice, which may ultimately lead to underweight, overweight, or obesity. The aim of this study is to evaluate whether poor oral status is associated with underweight or overweight/obesity, regardless of physical activity. ⋯ To our knowledge, this is one of the first studies associating poor oral health, represented by edentulism not rehabilitated with dentures, with unfavorable body mass, regardless of the two major confounders, physical activity and depression symptoms.

Comparative Study
Brain lipid composition in rabbits after total parenteral nutrition with two different lipid emulsions.
To study the changes occurring in brain lipid composition after the administration of total parenteral nutrition (TPN) by comparing two lipid emulsions, one with long-chain triacylglycerols (LCT) and the other with long-chain and medium-chain triacylglycerols (MCT/LCT 50%/50%). ⋯ The lipid emulsions administered in TPN, especially those prepared exclusively with LCT, cause changes in the brain lipid polar fractions of young rabbits.
