5 mg kg-1?day-1 silibinin, starting at the beginning of the protocol). Both subcutaneous and visceral fat was measured. Homeostasis model assessment-IR index (HOMA-IR), intraperitoneal glucose tolerance test and insulin tolerance test (ITT) were performed. The expression of adipose triglyceride lipase (ATGL) and of genes associated with hepatic gluconeogenesis was evaluated. Results: Silibinin intervention significantly protected liver function, down-regulated serum fat, and improved IR, as shown by decreased HOMA-IR

and increased ITT slope. Silibinin markedly prevented visceral obesity by reducing visceral fat, enhanced lipolysis by up-regulating ATGL expression and inhibited gluconeogenesis by down-regulating FK506 associated https://www.selleckchem.com/products/atezolizumab.html genes such as Forkhead box O1, phosphoenolpyruvate carboxykinase and glucose-6-phosphatase. Conclusion: Silibinin was effective in ameliorating IR in NAFLD rats. Reduction of visceral obesity, enhancement of lipolysis and inhibition of gluconeogenesis might be the underlying mechanisms.

Although enteral nutrition is preferred over parental, Carnitine dehydrogenase there is no data to support the notion that ICU patients benefit from receiving the same caloric intake recommended for the general population. We hypothesized that hypocaloric nutrition support will lead to a decreased rate of infection, shorter ICU stay, and decreased mortality

compared to eucaloric nutrition support. Methods: A single-institution, randomized-controlled trial was conducted in adult patients admitted to the surgical ICU between 2008 and 2011. Patients were randomized to receive either the standard calculated daily caloric requirement of 25-30 kcal/kg/day (eucaloric) or 50% of that value (hypocaloric) via TPN or enteral tube feeds, with the same protein provision in each group (1.5 g/kg/day). Based on intention to treat, univariate analysis was performed with development of infection as the primary outcome. Results: 83 patients were enrolled and randomized, 41 to hypocaloric and 42 to eucaloric. There were 82 infections in the hypocaloric group and 66 in the eucaloric group, with no significant difference in mean APACHE score at time of admission (16.6 [SE 0.9] vs 17.3 [0.8]; p=0.58), mean number of infections per patient (2.0 [SE 0.6] vs 1.6 [0.2]; p=0.50), the percentage of patients acquiring infection (71% vs 76%; p=0.57), mean ICU length of stay (16.7 [SE 2.7] vs 13.5 [1.1] days; p=0.28), mean hospital length of stay (35.2 [SE 4.9] vs 31.0 [2.5] days; p=0.
