BACKGROUND: Ganglioside GM3 is an abundant constituent of the plasma membrane where its accumulation attenuates insulin receptor signaling. Considering the role of skeletal muscles for insulin-stimulated glucose uptake, the aim of this study was to determine the expression of GM3 and its precursors in skeletal muscle of diabetes mellitus type 1 (DM1) and type 2 (DM2) rat models. METHODS: Diabetes was induced by streptozotocin (55 mg/kg for DM1 and 35 mg/kg for DM2) injection to male Sprague-Dawley rats which were fed with normal pellet diet (DM1 type) or high-fat diet (DM2 type)...

BACKGROUND & AIMS: Steatotic liver responds with increased hepatocellular injury when exposed to an ischemic-reperfusion insult. Increasing evidence supports the role of immune cells as key mediators of this injury in a normal (lean) state, but data about their role in a steatotic liver are practically non-existent. The objective of the current study was to delineate contribution of specific phenotypes of T cells and adhesion molecules in exacerbated cell death in steatotic liver injury...

Nucleobindin-1 has high sequence similarity to nucleobindin-2, which encodes the anorectic and metabolic peptide, nesfatin-1. We previously reported a nesfatin-1-like peptide (NLP), anorectic in fish and insulinotropic in mice islet beta-like cells. The main objective of this research was to determine whether NLP is a metabolic regulator in male Wistar rats. A single intraperitoneal (IP) injection of NLP (100 μg/kg BW) decreased food intake and increased ambulatory movement, without causing any change in total activity or energy expenditure when compared to saline-treated rats...

Endothelial injury plays an important role in atherosclerosis (AS). Kangshuanyihao formula uses therapeutic principles from Chinese medicine to supplement Qi, thereby promoting blood circulation, and remove blood stasis. The mechanism by which the formula inhibits endothelial injury was examined in a rat model of 1,25-dihydroxyvitamin D3 (VD3) intraperitoneal injection and high-fat-induced endothelial injury. Rats were randomly divided into the model, high-dose, middle-dose, low-dose, positive drug (rosuvastatin), and combination (positive drug + middle-dose) groups; 10 Sprague-Dawley rats served as the blank group...

Insecticidal effects of Bacillus thuringiensis Cry toxins in hemocoel of larvae have not been properly evaluated. In the present study, hemocoelic injection of four representative Cry toxins i.e., Cry1Aa, Cry1Ab, Cry1Ac, and DOR5 to an economically important lepidopteran insect pest Achaea janata, induced larval mortality, reduced larval growth rate and gave rise to smaller pupae, all in a dose-dependent manner. We observed extensive degeneration as well as the disintegration of larval tissues, most notably, fat body, and the possible involvement of lysosomal enzymes in tissue histolysis...

Mitochondrial dysfunction is a major and common mechanism in developing non-alcoholic fatty liver disease (NAFLD). Replacement of dysfunctional mitochondria by functional exogenous mitochondria may attenuate intrahepatic excessive lipid and recover hepatocyte function. However, no data shows that mitochondria can be systemically administrated to animals to date. Here we suggest that mitochondria isolated from hepatoma cells are used as a mitotherapy agent to treat mouse fatty liver induced by high-fat diets...

Reduced hepatic glycogenesis is one of the most important causes of metabolic abnormalities in non‑alcoholic fatty liver disease. Octreotide, a somatostatin analogue, has been demonstrated to promote weight loss and improve metabolic disorders in mice with high fat diet (HFD)‑induced obesity. However, whether octreotide affects hepatic glycogenesis is unknown. The aim of the present study was to verify the effects of octreotide on hepatic glycogenesis in rats with HFD‑induced obesity. Male Sprague‑Dawley rats were fed a standard diet or a HFD for 24 weeks...

BACKGROUND: Ghrelin is the only orexigenic hormone known to stimulate food intake and promote obesity and insulin resistance. We recently showed that plasma ghrelin is controlled by butyrylcholinesterase (BChE), which has a strong impact on feeding and weight gain. BChE knockout (KO) mice are prone to obesity on high-fat diet but hepatic BChE gene transfer rescues normal food intake and obesity resistance. However, these mice lack brain BChE and still develop hyperinsulinemia and insulin resistance, suggesting essential interactions between BChE and ghrelin within the brain...

The use of stable isotopes is a reliable and risk-free alternative to radioactive tracers for directly examining in vivo fatty acid (FA) metabolism. However, very limited information is available in ruminants, and none is available in sheep. Therefore, we conducted an experiment in dairy ewes to determine, for the first time in this species, the uptake, Δ(9)-desaturation, and secretion of (13)C-labeled stearic acid (SA) into milk with the aim of measuring in vivo endogenous synthesis of milk oleic acid (OA) and stearoyl-CoA desaturase activity...

Mycobacterium chelonae is a nontuberculous mycobacterium, classified as a Runyon type IV mycobacterium. In relation to humans, it is most commonly associated with tissue trauma or pulmonary infections. The majority of medical reports describe finding M. chelonae in the surgical setting, attributing infection to inadequate sterilization of surgical equipment. Symptoms are often nonspecific and include pain, erythema, and draining subcutaneous nodules and skin lesions. Therefore, the diagnosis of M. chelonae is often difficult to establish without prior suspicion of the disease, but can be confirmed with culture...

Hypertriglyceridemia (HTG) aggravates the course of acute pancreatitis (AP). Intestinal barrier dysfunction is implicated in the pathogenesis of AP during which dysbiosis of intestinal microbiota contributes to the dysfunction in intestinal barrier. However, few studies focus on the changes in intestine during HTG-related acute necrotizing pancreatitis (ANP). Here, we investigated the changes in intestinal microbiota and Paneth cell antimicrobial peptides (AMPs) in HTG-related ANP (HANP) in rats. Rats fed a high-fat diet to induce HTG and ANP was induced by retrograde injection of 3...

BACKGROUND: The prominent nasolabial fold is a distinct feature of the aging midface. As minimally invasive procedures have become mainstream, chemodenervation is a preferred method for treating dynamic facial rhytids. We therefore sought to identify relevant nasolabial fold and midfacial muscular anatomy to determine the ideal location of neuromodulation to improve the aesthetics of the midface and nasolabial fold without altering the upper lip and smile. METHODS: Twelve hemifacial cadaveric dissections were performed to identify midface muscle origin, insertion, width, vector of pull, and neighboring structures...
