Alcoholic liver diseases and virus-induced hepatic dysfunctions are prevalent in western countries. Evidence also suggests that hyperglycemia and insulin resistance are key players in the development of hepatic diseases and their complications. Since the comorbid diseases like obesity, diabetes and vascular dysfunctions primarily affect liver, the modern therapies against other hepatic dysfunctions are becoming a major challenge to treat. In addition to these, polypharmacy and adverse drug reactions (ADRs) are further aggravating the phenomenon...

Resistance training (RT) and high-quality protein ingestion improves muscle mass (MM) and strength (MS). However, no study has evaluated the effect of ingesting milk plus soy protein (SOY) on MM and MS in postmenopausal women (PW). Thus, the aim of this study was to evaluate the effects of adding SOY to milk on MM and MS after 16 weeks of RT. Thirty-two PW were randomized and allocated into two groups: placebo and RT (PL+RT, n = 16) and SOY and RT (SOY+RT, n = 16). The SOY+RT received 25 g of SOY while the PL+RT received 25 g of maltodextrin (placebo)...

Polyphenolic compounds have been suggested to be involved in the preservation of neural function via the production of neurotrophic factors in the brain. The nonedible joint part of lotus root (a rhizome of Nelumbo nucifera) has been reported to contain large amounts of polyphenolic compounds and, therefore, is expected to improve neural function by stimulating the production of brain-derived neurotrophic factor (BDNF) in glial cells. The effect of the aqueous extract prepared from the joint part of lotus root on BDNF gene expression was examined in C6 glioma cells as an in vitro model...
