BACKGROUND The endoplasmic reticulum (ER) is the cellular site for protein folding. ER stress occurs when protein folding capacity is exceeded. This stress induces a cyto-protective signaling cascades termed the unfolded protein response (UPR) aimed at restoring homeostasis. While acute ER stress is lethal, chronic sub-lethal ER stress causes cells to adapt(More)
Nonalcoholic fatty liver disease (NAFLD) is a leading cause of liver disease in developed countries. Its frequency is increasing in the general population mostly due to the widespread occurrence of obesity and the metabolic syndrome. Although drugs and dietary supplements are viewed as a major cause of acute liver injury, drug induced steatosis and(More)
T lymphocyte-expressing natural killer (NK) cell markers (NKT cells) play a role in immune regulation. Our aim was to evaluate the in vivo effect of adoptive transfer of immune-programmed NKT cells. Colitis was induced in C57/B6 mice by 2,4,6-trinitrobenzenesulfonic acid. NKT, CD4, CD8 lymphocytes, and dendritic cells (DC) were prepared from spleens of(More)
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is the most common cause of elevated alanine aminotransferase (ALT). NAFLD is associated with insulin resistance and hepatic inflammation. Similarly, patients with depression exhibit insulin resistance and increased inflammatory markers. However, no study has shown a clear association between elevated ALT(More)
BACKGROUND AND AIMS C/EBP homologous protein (CHOP) plays pro-apoptotic roles in the integrated stress response. Recently, a tumor suppressive role for CHOP was demonstrated in lung cancer via regulation of tumor metabolism. To explore the role of CHOP in hepatocarcinogenesis, we induced hepatocellular carcinoma (HCC) in wild type (wt) and CHOP knockout(More)
The intestinal microbiota undergoes diurnal compositional and functional oscillations that affect metabolic homeostasis, but the mechanisms by which the rhythmic microbiota influences host circadian activity remain elusive. Using integrated multi-omics and imaging approaches, we demonstrate that the gut microbiota features oscillating biogeographical(More)
Infliximab, a monoclonal anti-TNF-alpha antibody, is commonly used for treatment of moderate to severe Crohn's disease (CD). Its role in the treatment for ulcerative colitis (UC) remains controversial. We review the role of TNF-alpha in the pathogenesis of UC and describe the randomized, double-blind, placebo-controlled trials and systematic reviews that(More)
AIM To describe the relationships between non-alcoholic fatty-liver disease (NAFLD) patient's disease consequences and treatment perceptions, self-efficacy, and healthy lifestyle maintenance. METHODS A cross-sectional study among 146 ultrasound diagnosed NAFLD patients who visited the fatty liver clinic at the Tel-Aviv Medical Center. Eighty-seven of(More)
AIM To investigate predictors for fibrosis specifically in a high risk population of morbidly obese patients, including detailed evaluation of lifestyle. METHODS We conducted a cross-sectional study among morbidly obese patients attending the bariatric clinic at the Tel-Aviv Medical Center between the years 2013-2014 with body mass index (BMI) above 40 or(More)
AIM To assess the practice of caring for acute liver failure (ALF) patients in varying geographic locations and medical centers. METHODS Members of the European Acute Liver Failure Consortium completed an 88-item questionnaire detailing management of ALF. Responses from 22 transplantation centers in 11 countries were analyzed, treating between 300 and 500(More)
