Marontades pumilum is claimed to have beneficial effects in the treatment of diabetes mellitus (DM), however the underlying mechanisms were not fully identified. In this study, we hypothesized that M. pumilum could help to enhance cellular glucose uptake and reduces pancreatic complications, which contributed towards its beneficial effects in DM. METHODS: Two parameters were measured (i) rate of glucose uptake by 3T3-L1 adipocyte cells in-vitro (ii) degree of pancreatic destruction in streptozotocin-nicotinamide induced male diabetic rats receiving M...

BACKGROUND AND OBJECTIVE: Perfluoroalkyl substances (PFASs), including perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorohexane sulfonic acid (PFHxS), and perfluorononanoic acid (PFNA), have been associated with adverse bone, and metabolic changes in adults. However association of PFASs with bone health in children is understudied. Considering their role as endocrine disruptors, we examined relationships of four PFASs with bone health in children. METHODS: In a cross sectional pilot study, 48 obese children aged 8-12 years were enrolled from Dayton's Children Hospital, Ohio...

Hyperglycemia and dysregulation of lipid metabolism play a crucial role in metabolic dysfunction. The aims of present study were to evaluate the ameliorative effect of the ethyl acetate fraction of Chinese olive fruit extract (CO-EtOAc) on high-fat diet (HFD) and streptozotocin (STZ)-induced diabetic rats. CO-EtOAc, rich in gallic acid and ellagic acid, could markedly decreased the body weight and epididymal adipose mass. In addition, CO-EtOAc increased serum HDL-C levels, hepatic GSH levels, and antioxidant enzyme activities; lowered blood glucose, serum levels of total cholesterol (TC), triglycerides (TG), bile acid, and tumor necrosis factor alpha (TNFα); and reduced TC and TG in liver...

Eukaryotic translation initiation factor 2 (eIF2) is a heterotrimeric GTPase, which plays a critical role in protein synthesis regulation. eIF2-GTP binds Met-tRNAi to form the eIF2-GTP•Met-tRNAi ternary complex (TC), which is recruited to the 40S ribosomal subunit. Following GTP hydrolysis, eIF2-GDP is recycled back to TC by its guanine nucleotide exchange factor (GEF), eIF2B. Phosphorylation of the eIF2α subunit in response to various cellular stresses converts eIF2 into a competitive inhibitor of eIF2B, which triggers the integrated stress response (ISR)...

We report a case of fibromatosis demonstrating prostate-specific membrane antigen (PSMA)-positive scan. A 76-year-old man was under assessment because of rising prostate-specific antigen level. Bone scan showed abnormal soft tissue uptake of Tc-MDP adjacent to the right scapula, compatible with a mass in MRI, thereafter. Because of the unavailability of Ga-PSMA scan in our department and also high cost in other centers, the patient underwent Lu-PSMA for more assessment, which revealed PSMA-avid mass. Pathologic examination confirmed the diagnosis of low-grade fibromatosis...

The triterpenoid ursolic acid (UA) has been proposed as a potential cancer chemopreventive agent in many preclinical and clinical studies. In the present work, we aimed to characterize the pharmacokinetics (PK) of UA and to quantitatively assess the anti-oxidative and anti-inflammatory effects of UA, which are potentially linked to its chemopreventive efficacy. UA was administered intravenously (i.v., 20 mg/kg) or by oral gavage (100 mg/kg) to male Sprague-Dawley rats, and blood samples were collected at a series of designated time points...

Lifestyle modifications are recommended as the initial treatment for high blood pressure. The influence of dyslipidemia might be via moderate arterial stiffness, which results in hypertension and cardiovascular disease. We used data from a subgroup of the lifestyle, level of serum lipids/carotid femoral-pulse wave velocity (CF-PWV) Susceptibility BEST Study, a population-based study of community-dwelling adults aged 45-75 years. The serum lipid level and CF-PWV were measured at baseline, and lifestyle such as smoking status, sleeping habits, and the level of oil or salt intake was determined with the use of a validated questionnaire during follow-up...

NAFLD is a chronic liver disease that affects a high proportion of the world's population which causes metabolic and hepatic damages. Rosa damascena Mill is traditionally used as a dietary supplement for liver disorders. This study was carried out to determine the beneficial effect of standardized extract of R. damascena on animal model of nonalcoholic fatty liver disease (NAFLD). NAFLD was induced by high-fat diet (HFD) in Wistar rats. HFD rats showed an increase (p < 0.05) in the plasma lipid levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and reduced the high-density lipoprotein (HDL) levels...

Ectopic thoracic kidney is an extremely rare condition caused by the abnormal location of one or both kidneys in the thoracic cavity. They are usually discovered incidentally on routine imaging. Although commonly asymptomatic, thoracic kidneys are at a risk of malrotation, pelviureteric junction obstruction, and subsequent obstructive nephropathy, by virtue of their long pedicle. We present a case report of an incidental thoracic kidney, for which a (99m)technetium-mercaptoacetyltriglycine ((99m)Tc-MAG3) renogram was performed to assess the baseline renal function...

A systematic way of improving exchange-correlation energy functionals of density functional theory has been to make them satisfy more and more exact relations. Starting from the initial generalized gradient approximation (GGA) functionals, this has culminated into the recently proposed SCAN (strongly constrained and appropriately normed) functional that satisfies several known constraints and is appropriately normed. The ultimate test for the functionals developed is the accuracy of energy calculated by employing them...
