Obesity, which is caused by an energy imbalance between calorie intake and consumption, has become a major international health burden. Obesity increases the risk of insulin resistance and age-related cognitive decline, accompanied by peripheral inflammation. (-)-Epigallocatechin-3-gallate (EGCG), the major polyphenol in green tea, possesses antioxidant, anti-inflammatory, and cardioprotective activities; however, few reports have focused on its potential effect on cognitive disorders. In this study, our goal was to investigate the protective effects of EGCG treatment on insulin resistance and memory impairment induced by a high-fat and high-fructose diet (HFFD)...

OBJECTIVE: To determine the effects of exogenous glucagon-like peptide-2 (GLP-2), with or without massive distal bowel resection, on adaptation of jejunal mucosa, enteric neurons, gut hormones and tissue reserves in rats. BACKGROUND: GLP-2 is a gut hormone known to be trophic for small bowel mucosa, and to mimic intestinal adaptation in short bowel syndrome (SBS). However, the effects of exogenous GLP-2 and SBS on enteric neurons are unclear. METHODS: Sprague Dawley rats were randomized to four treatments: Transected Bowel (TB) (n = 8), TB + GLP-2 (2...

Human low-density lipoprotein (LDL) is a highly complex nano-particle built up of various lipid classes and a single large protein moiety (apoB-100) owning essential physiological functions in the human body. Besides its vital role as a supplier of cholesterol and fat for peripheral tissues and cells, it is also a known key player in the formation of atherosclerosis. Due to these important roles in physiology and pathology the elucidation of structural and dynamical details is of great interest. In the current study we drew a broader picture of LDL dynamics using elastic incoherent neutron scattering (EINS) as a function of specified temperature and pressure points...

Circadian clocks orchestrate many physiological processes in adult organisms. For example, rhythmic feeding behavior is regulated by the central clock in the nervous system in coordination with metabolic rhythms, which in turn depend mostly on peripheral clocks localized in many tissues. Disruption of the circadian clock leads to metabolic dysregulation both in mammals and in the model insect Drosophila melanogaster. Circadian coordination of feeding and metabolism has been studied mainly in adult insects and not in larval stages, which are dramatically different from adults in species with complete full metamorphosis...

Vitamin D has been reported to have anti-inflammatory properties in in vitro and animal studies, which are thought to occur via inhibition of the nuclear factor kappa-B (NFκB) pathway. However, the association between vitamin D and in vivo NFκB activity in humans has not previously been reported. The aim of the present study was to examine the associations between circulating 25-hydroxyvitamin D (25(OH)D) concentrations and NFκB activity in peripheral blood mononuclear cells (PBMCs) as well as plasma inflammatory markers in healthy individuals...

AIM: Protein-energy wasting (PEW) is prevalent in haemodialysis. Obesity is an independent risk factor of kidney insufficiency, but it is proposed to have beneficial roles in better outcomes in the final stage of disease. Better nutritional status and body reserves are among probable mechanisms, but direct examinations are limited. The present study aimed to investigate whether obese patients have preferable nutritional status compared to normal weight patients based on malnutrition inflammation score (MIS) and other PEW parameters in haemodialysis...

AIM: Impaired autonomic function could be the mechanism for the development of cardiometabolic diseases in obesity. Hence, simple anthropometric measures of overall and central obesity could be screening markers for autonomic imbalance. We analysed the relationship between heart rate variability (HRV) parameters and obesity indicators. METHODS: Sixty-three obese women underwent blood pressure, lipids and anthropometric measurements, body composition assessment, HOMA (homeostasis model assessment) index calculation and short-term HRV analysis...

The present study compared the effects of diets formulated with fibers of different fermentability and protein sources of animal or vegetable origins on old and adult dogs. The experiment was organized in a 3 (diets) × 2 (ages) factorial arrangement, totaling 6 treatments. Thirty-six Beagle dogs were used (18 old dogs [10.2 ± 1.0 yr] and 18 young adult dogs [2.6 ± 0.9 yr]), with 6 dogs per treatment. Three diets with similar compositions were used: a nonfermentable insoluble fiber source (sugarcane fiber) and chicken byproduct meal (nonfermentable fiber [NFF] diet), a fermentable fiber source (beet pulp) and chicken byproduct meal (fermentable fiber [FF] diet), and soybean meal as a protein and fiber source (soybean meal [SM] diet)...

The intramuscular fat (IMF) content of the LM, also known as marbling, is particularly important in determining the price of beef in Korea, Japan, and the United States. Deposition of IMF is influenced by both genetic (e.g., breed, gender, and genotype) and nongenetic factors (e.g., castration, nutrition, stressors, animal weight, and age). Castration of bulls markedly increases deposition of IMF, resulting in improved beef quality. Here, we present a comparative gene expression approach between bulls and steers...

Obesity is associated with chronic low-grade inflammation, and metabolic regulators linking obesity to inflammation have therefore received much attention. Secreted C1q/TNF-related proteins (CTRPs) are one such group of regulators that regulate glucose and fat metabolism in peripheral tissues and modulate inflammation in adipose tissue. We have previously shown that expression of CTRP6 is up-regulated in leptin-deficient mice and, conversely, down-regulated by the anti-diabetic drug, rosiglitazone. Here, we provide evidence for a novel role of CTRP6 in modulating both inflammation and insulin sensitivity...

OBJECTIVE: Youth type 2 diabetes mellitus (T2DM) occurs decades earlier than adult T2DM and is characterized by high therapeutic failure rates and decreased response to insulin sensitizers suggesting a more severe disease process than in adults. To explain these observations, we hypothesized that insulin resistance is worse in obese youth than adults with impaired glucose tolerance (IGT), a state of high-risk for T2DM. As proof-of-concept, we compared insulin sensitivity between BMI-, sex-, and race-matched obese youth vs adults with IGT...

High protein diet (HPD) curtails obesity and/or fat mass but it is unknown whether it reverses neuroinflammation, altered glucose levels, cholecystokinin (CCK) sensitivity and gut microbiome in rats fed a Western diet (WD)-induced obesity (DIO). Male rats fed a WD (high fat and sugar) for 12 weeks were switched to a HPD for 6 weeks. Body composition, food intake, meal pattern, sensitivity to intraperitoneal CCK-8S, blood glucose, brain signaling, and cecal microbiota were assessed. Compared to normal diet, WD increased body weight (9...

Transgender people have a gender that is not in agreement with their birth sex. Previous barriers, including lack of provider knowledge, has created significant healthcare disparities for this population. Recent societal changes are increasing the numbers of transgender people seen by primary care. Ten key principles are provided to help primary practitioners create more welcoming environments and provide quality care to transgender patients. Overall, all members of the health care team (primary and specialty) need to become aware of the transition process and maintain communication regarding risks, benefits and goals...

Reports of acquired ATTRm in domino liver transplant (DLT) recipients are infrequent and the approach to management is unknown. We describe two patients, an inherited ATTRm patient who underwent liver transplant and his liver recipient who developed acquired ATTRm 8years following transplantation. The clinical manifestations of amyloidosis were similar between patients and consisted of peripheral neuropathy, diarrhea and weight loss. Following liver transplantation, the DLT donor went into remission for 4years, but eventually progressed and died...

Atrophy and fatty infiltration of lower extremity muscle after spinal cord injury (SCI) predisposes individuals to metabolic syndrome and related diabetes and cardiovascular disease. The objective of this study was to prospectively measure changes in muscle atrophy and fat content of distal lower extremity muscles and explore related factors in a cohort of adults with chronic SCI and diverse impairments. Muscle cross-sectional area and density were calculated from peripheral quantitative computed tomography scans of the 66% site of the calf from 70 participants with chronic SCI (50 male, mean age 49 years, C2-T12, American Spinal Injury Association Impairment Scale A-D) at study enrollment and annually for 2 years...

Forty percent of American women are obese and at risk for type II diabetes, impaired immune function, and altered microbiome diversity, thus impacting overall health. We investigated whether obesity induced by an excess calorie, high fat diet containing hydrogenated fats, fructose, and coconut oil (HFD) altered glucose homeostasis, peripheral immunity, and urogenital microbial dynamics. We hypothesized that HFD would cause hyperglycemia, increase peripheral inflammation, and alter urogenital microbiota to favor bacterial taxonomy associated with inflammation...

Dopaminergic signaling differences in the nucleus accumbens (NAcc) seemingly predispose rats to adopt different physical activity behaviors. Physical activity behavior may also be regulated through peripheral mechanisms (i.e., muscle and fat-derived as well as hormonal signals). We hypothesize that physical activity behavior is regulated by the convergence of central and peripheral mechanisms onto the nucleus accumbens.

PURPOSE: Obesity and its metabolic impairments are discussed as major risk factors for sarcopenia leading to sarcopenic obesity. Cushing's syndrome is known to be associated with obesity and muscle atrophy. We compared Cushing's syndrome with matched obese controls regarding body composition, physical performance, and biochemical markers to test the hypothesis that Cushing's syndrome could be a model for sarcopenic obesity. METHODS: By propensity score matching, 47 controls were selected by body mass index and gender as obese controls...

OBJECTIVE: Metformin, the first line drug for treatment of type 2 diabetes, suppresses hepatic gluconeogenesis and reduces body weight in patients, the latter by an unknown mechanism. METHODS: Mice on a high fat diet were continuously fed metformin in a therapeutically relevant dose, mimicking a retarded formulation. RESULTS: Feeding metformin in pharmacologically relevant doses to mice on a high fat diet normalized HbA1c levels and ameliorated glucose tolerance, as expected, but also considerably slowed down weight gain...

Protective effects of granulocyte colony stimulating factor (G-CSF) in acute liver injury via marrow cell mobilization have been reported in several studies. But exact mode of action and optimal protocol of G-CSF has been still doubt in chronic disease. Here we investigated mode of action and optimization of G-CSF as a treatment for non-alcoholic fatty liver disease (NAFLD). Various doses of conventional G-CSF (30 μg/kg once weekly, once daily for 5 days, twice weekly) and long acting G-CSF (30 μg/kg once a month) were evaluated in two kinds of NAFLD animal models to optimize the G-CSF protocol...
