In conclusion, TSF improved lipid accumulation and hepatic steatosis by inducing the AMPK/SIRT1 pathway-mediated autophagy. Introduction Nonalcoholic fatty liver disease (NAFLD) has become a worldwide health concern due to the increased incidence of obesity and diabetes. In addition, NAFLD is closely associated with the risk factors of coronary heart disease, such as metabolic syndrome, diabetes mellitus, and dyslipidemia, which are considered to be the leading causes of death (Wiest et al., 2017). Although our understanding of the pathogenesis of NAFLD has significantly improved, there is still no effective medica...

In this study, we explored the effect of vitamin B12 on nerve regeneration after TBI both in vivo and in vitro. Meanwhile, we investigated the role of ER stress during the vitamin B12 treatment for TBI by inspecting changes in neuronal apoptosis, microtubule, myelin regeneration, and axonal growth. Materials and Methods Animals Adult C57BL/6 male mice aged 6–8 weeks and weighing 20–26 g were purchased from the Animal Center of the Chinese Academy of Sciences (Shanghai, China). Animals were housed under a 12-h light/dark cycle at 21–23°C and provided access to food and water ad libitum. The care and...

In this study, we aimed to investigate the seasonal changes in retention and mobilization of lipids from various categories, which are expected to significantly impact on metabolisms, in wild Scandinavian brown bears (Ursus arctos). For this purpose and because lipids are found under many different forms and have pleiotropic actions, we used a lipidomic approach to determine the lipid composition in skeletal muscle and white adipose tissues (to assess lipid retention), and in blood plasma (reflecting lipid trafficking) of bears during winter hibernation and the summer active period. Specifically, we hypothesized that bears...

Farb* Laboratory of Molecular Neurobiology, Department of Pharmacology and Experimental Therapeutics, Boston University School of Medicine, Boston, MA, United States Memory dysfunction is a symptomatic feature of many neurologic and neuropsychiatric disorders; however, the basic underlying mechanisms of memory and altered states of circuitry function associated with disorders of memory remain a vast unexplored territory. The initial discovery of endogenous neurosteroids triggered a quest to elucidate their role as neuromodulators in normal and diseased brain functio...

Publication date: July 2018Source: Anaesthesia &Intensive Care Medicine, Volume 19, Issue 7Author(s): Matthew Charlton, Jonathan P. ThompsonAbstractHeart failure (HF) and coronary insufficiency are common amongst surgical and critical care patients. Both are chronic conditions interrupted by acute episodes. HF activates neurohormonal mechanisms that worsen renal and cardiac function. Acute heart failure (AHF) commonly presents with dyspnoea as a consequence of systolic and/or diastolic dysfunction. Goals of treatment are symptom relief, to maintain tissue perfusion and optimize cardiac function. Diuretics and vasodilat...

Conclusions: Findings from our experimental model suggest that the offspring of dams exposed to ozone during implantation had reduced growth compared with controls, possibly as a consequence of ozone-induced vascular dysfunction. https://doi.org/10.1289/EHP2019 Received: 10 April 2017 Revised: 7 November 2017 Accepted: 13 November 2017 Published: 21 December 2017 Address correspondence to C.N.
