BACKGROUND: Novel tobacco products entering the US market include electronic cigarettes (ECIGs) and products advertised to "heat, not burn" tobacco. There is a growing literature regarding the acute effects of ECIGs. Less is known about "heat, not burn" products. This study's purpose was to expand existing clinical laboratory methods to examine, in cigarette smokers, the acute effects of a "heat, not burn" "loose-leaf tobacco vaporizer" (LLTV). METHODS: Plasma nicotine and breath carbon monoxide (CO) concentration and tobacco abstinence symptom severity were measured before and after two 10-puff (30-s interpuff interval) product use bouts separated by 60min...

BACKGROUND: Dietary sugar and starch affect plasma glucose and insulin concentrations. Little information is available about the effect of dietary fibre on plasma glucose and insulin concentration. It is hypothesized that different dietary fibre compositions will alter post-prandial glycaemic- and insulinemic index of test meals. The objective was to measure postprandial glucose and insulin concentrations in horses fed meals of different fibre compositions. METHODS: Blood was drawn via jugular vein puncture and the glycaemic and insulinemic index were calculated...

Spinal cord injury (SCI) causes a significant amount of bone loss, which results in osteoporosis (OP). The neuropeptide substance P (SP) and SP receptors may play important roles in the pathogenesis of OP after SCI. To identify the roles of SP in the bone marrow mesenchymal stem cell derived osteoblasts (BMSC-OB) in SCI rats, we investigated the expression of neurokinin-1 receptors (NK1R) in BMSC-OB and the effects of SP on bone formation by development of BMSC-OB cultures. Sixty young male Sprague-Dawley rats were randomized into two groups: SHAM and SCI...

Clinical findings and data obtained in animal models indicate that nutrient uptake and exposure to environmental agents during pregnancy may affect fetal/newborn gestational programming thereby resulting in obesity and/or obesity-related disorders in offspring. Human amniotic mesenchymal stem cells (hA-MSCs) differentiate into adipocytes, and are thus a suitable model to investigate adipocyte functions in obesity. The aim of this study was to elucidate the miRNome of hA-MSCs and its contribution to obesity in pregnancy...

As reported by Alfred Werner in 1911-1912, salts of the formally D3 symmetric [Co(en)3](3+) (en = ethylenediamine) trication were among the first chiral inorganic compounds to be resolved into enantiomers, the absolute configurations of which are denoted Λ (left handed helix) or Δ (right handed helix). After a >100 year dormant period during which few useful reactions of these substitution inert complexes were described, carbon substituted derivatives have recently been found to be potent catalysts for enantioselective organic synthesis...

BACKGROUND: Murine models of diabetes and obesity have provided insight into the pathogenesis of impaired epithelialization of excisional skin wounds. However, knowledge of postischemic myocutaneous revascularization in these models is limited. MATERIALS AND METHODS: A myocutaneous flap was created on the dorsum of wild type (C57BL/6), genetically obese and diabetic (ob/ob, db/db), complementary heterozygous (ob(+)/ob(-), db(+)/db(-)), and diet-induced obese (DIO) mice (n=48 total; five operative mice per strain and three unoperated mice per strain as controls)...

BACKGROUND AND AIMS: Oxidative disturbance is an important factor involved in the etiology of comorbidities associated with obesity. Genetic polymorphisms such as SOD1 -251A>G, SOD2 47 C>T, CAT -21A>T and CAT -262 C>T have been described to alter the activity of antioxidant enzymes. The aim of the present work was to analyze the association of the mentioned SNPs with obesity and their relationship with anthropometric and clinical variables in this group. METHODS: The study included 416 Mexican women (208 normal weight, NW and 208 subjects with obesity, OB)...

The systemic administration of bisphosphonates (BPs) for the treatment of metabolic diseases characterized by abnormal bone loss suffers from several adverse side effects, which can be reduced by implementation of alternative modes of administration. In this work, glutaraldehyde cross-linked gelatin scaffolds are proposed as delivery systems of calcium alendronate monohydrate (CaAL•H2 O). The 3D highly porous scaffolds display a relevant interconnected porosity (>94%), independently from CaAL•H2 O content (0, 3, and 6 wt%)...

OBJECTIVE: Simulation training has been demonstrated to increase medical student confidence with vaginal deliveries; however, effect on skill performance is still lacking. To determine if integration of simulation training into the OB/GYN clerkship improves performance of vaginal deliveries, we assessed the effectiveness of simulation in third-year medical students. METHODS: During the OB/GYN clerkship, third-year students were assigned to receive vaginal delivery simulation (n=54) or cervical exam simulation (n=56), with each group serving as a simulation naïve control for the other skill...

Leptin plays a key role in the pathogenesis of obesity and depression via the long form of leptin receptor (LepRb). An animal model of comorbid obesity and depression induced by high-fat diet (HFD) combined with chronic unpredictable mild stress (CUMS) was developed to study the relationship between depression/anxiety-like behavior, levels of plasma leptin and LepRb in the brains between four groups of rats, the combined obesity and CUMS (Co) group, the obese (Ob) group, the CUMS group and controls. Our results revealed that the Co group exhibited most severe depression-like behavior in the open field test (OFT), anxiety-like behavior in elevated plus maze test (EMT) and cognitive impairment in the Morris water maze (MWM)...

The yield and quality of the broiler skin fat rendered through high and lower energy microwave rendering (3.6 W/g for 10 min and 2.4 W/g for 10 min for HEMR and LEMR, respectively), oven baking (OB, at 180 °C for 40 min), and water cooking (WC, boiling for 40 min) were compared. Microwave-rendered skin exhibited the highest yields and fat recovery rates, followed by OB, and WC fats (p<0.05). HEMR fat had the highest L*, a*, and b* values, whereas WC fat had the highest moisture content, acid values, and thiobarbituric acid (TBA) values (p<0...

Maternal obesity is proposed to alter the programming of metabolic systems in the offspring, increasing the risk for developing metabolic diseases; however, the cellular mechanisms remain poorly understood. Here, we used a nonhuman primate model to examine the impact of a maternal Western-style diet (WSD) alone, or in combination with obesity (Ob/WSD), on fetal skeletal muscle metabolism studied in the early third trimester. We find that fetal muscle responds to Ob/WSD by upregulating fatty acid metabolism, mitochondrial complex activity, and metabolic switches (CPT-1, PDK4) that promote lipid utilization over glucose oxidation...

The regenerative potential of tissue engineered bone constructs may be enhanced by in vitro co-culture and in vivo co-transplantation of vasculogenic and osteogenic (progenitor) cells. The objective of this study was to systematically review the literature to answer the focused question: in animal models, does co-transplantation of osteogenic and vasculogenic cells enhance bone regeneration in craniofacial defects, compared to solely osteogenic cell-seeded constructs? Following PRISMA guidelines, electronic databases were searched for controlled animal studies reporting co-transplantation of endothelial cells (EC) with mesenchymal stem cells (MSC) or osteoblasts (OB) in craniofacial critical-size bone defect (CSD) models...

Objectives Retirement of "baby boomer" physicians is a matter of growing concern in light of the shortage of certain physician groups. The objectives of this investigation were to define what constitutes a customary retirement age range of maternal-fetal medicine (MFM) physicians and examine how that compares with other obstetrician-gynecologist (ob-gyn) specialists. Study Design This descriptive study was based on American Medical Association Masterfile survey data from 2010 to 2014. Data from the National Provider Identifier were used to correct for upward bias in reporting retirement ages...

A co-occluded binary mixture of Helicoverpa armigera nucleopolyhedrovirus genotypes HearSP1B and HearLB6 at a 1:1 ratio (HearSP1B+HearLB6) was selected for the development of a virus-based biological insecticide, which requires an efficient large-scale production system. In vivo production systems require optimization studies in each host-virus pathosystem. In the present study, the effects of larval instar, rearing density, timing of inoculation, inoculum concentration and temperature on the production of HearSP1B+HearLB6 in its homologous host were evaluated...

BACKGROUND: Glucocorticoid-induced leucine zipper (GILZ) is a mediator of the anti-inflammatory activities of glucocorticoids. However, GILZ deletion does not impair the anti-inflammatory activities of exogenous glucocorticoids in mice arthritis models and GILZ could also mediate some glucocorticoid-related adverse events. Osteoarthritis (OA) is a metabolic disorder that is partly attributed to adipokines such as leptin, and we previously observed that glucocorticoids induced leptin secretion in OA synovial fibroblasts...
