BACKGROUND: Excess weight, unhealthy lifestyle habits and their sequelae have become a well-recognized public health problem in most countries. The objective of the study was to examine the relationship of adolescent overweight/obesity with behavioral habits and their association with blood pressure (BP) and lipid profile. METHODS: Anthropometric parameters, lifestyle, BP and lipid profile of 736 adolescents were evaluated cross-sectionally. The classifications of normal weight, overweight and obese were based on BMI z-scores...

BACKGROUND: The increasing incidence of childhood obesity is a significant public health challenge, the consequences of which extend across the life course. SUMMARY: Diet and exercise are clearly the major contributors to childhood obesity, but the factors predisposing to obesity may become established in the womb. Worryingly maternal overnutrition, in particular when it leads to obesity and diabetes, perpetuate an intergenerational cycle of obesity through its effects on placental function and fetal metabolism...

Background: The use of parenteral nutrition formulas is often associated with the development of hepatic steatosis. We have shown previously that the addition of a lipid emulsion (LE) rich in n-6 (ω-6) fatty acids (FAs) ameliorated triglyceride (TG) accumulation in the livers of nonobese mice fed a high-carbohydrate diet (HCD) for 5 wk. However, it remains unclear how rapidly this condition develops and whether it can be prevented by LE with or without a running wheel for voluntary exercise (Exe).Objective: We investigated in an 8-d study whether mice develop steatosis and whether the administration of LE with or without Exe reduces the concentration of total FAs and prevents an increase in the expression of genes in the liver associated with lipogenesis...

OBJECTIVE: To analyze intramyocellular lipids (IMCLs) and extramyocellular lipids (EMCLs) of the multifidus muscle (Mm) using MR spectroscopy (MRS) in chronic low back pain (CLBP) and control groups and to identify correlations with spino-pelvic alignment. METHODS: Forty (16 males, 24 females; mean age, 62.9 ± 1.9 years) patients whose visual analog scale scores were >30 mm for CLBP were included. Further, 40 control participants matched with the CLBP group subjects by sample size, gender and age (17 males, 23 females; mean age, 65...

The prevalence of obesity during pregnancy continues to increase at alarming rates. This is concerning as in addition to immediate impacts on maternal wellbeing, obesity during pregnancy has detrimental effects on the long-term health of the offspring through non-genetic mechanisms. A major knowledge gap limiting our capacity to develop intervention strategies is the lack of understanding of the factors in the obese mother that mediate these epigenetic effects on the offspring. We used a mouse model of maternal-diet induced obesity to define predictive correlations between maternal factors and offspring insulin resistance...

PURPOSE: Eccentric exercise training produces positive fitness and health outcomes, but whether this is also the case for descending stair walking (DSW) is unknown. This study investigated the hypothesis that DSW would improve insulin sensitivity, lipid profiles and physical fitness better than ascending stair walking (ASW). METHODS: Elderly (≥60 y) obese women were placed to either DSW or ASW group (n=15/group). An elevator was used to eliminate ascending stairs for DSW, and descending stairs for ASW...

Cardiovascular disease is a significant and ever-growing problem in the United Kingdom, accounting for nearly one-third of all deaths and leading to significant morbidity. It is also of particular and pressing interest as developing countries experience a change in lifestyle which introduces novel risk factors for cardiovascular disease, leading to a boom in cardiovascular disease risk throughout the developing world. The burden of cardiovascular disease can be ameliorated by careful risk reduction and, as such, primary prevention is an important priority for all developers of health policy...

TFE3 and TFEB are members of the MiT family of HLH-leucine zipper transcription factors. Recent studies demonstrated that they bind overlapping sets of promoters and are post-transcriptionally regulated through a similar mechanism. However, while Tcfeb knockout (KO) mice die during early embryonic development, no apparent phenotype was reported in Tfe3 KO mice. Thus raising the need to characterize the physiological role of TFE3 and elucidate its relationship with TFEB TFE3 deficiency resulted in altered mitochondrial morphology and function both in vitro and in vivo due to compromised mitochondrial dynamics...

Alpha-linolenic acid (ALA) supplementation or exercise training can independently prevent hepatic lipid accumulation and reduced insulin signaling, however, this may occur through different mechanisms-of-action. In the current study, obese Zucker rats displayed decreased phospholipid (PL) content in association with hepatic lipid abundance, and therefore, we examined whether ALA and exercise training would prevent these abnormalities differently to reveal additive effects on the liver. To achieve this aim, obese Zucker rats were fed control diet alone or supplemented with ALA, and were sedentary or exercise trained for 4 weeks (C-Sed, ALA-Sed, C-Ex, ALA-Ex)...

OBJECTIVE: ANGPTL7 is a member of the Angiopoietin-like (ANGPTL) protein family that is composed of eight proteins (1-8). Increasing evidence is associating ANGPTL proteins to obesity and insulin resistance. The biological role of ANGPTL7 is yet to be understood except for a recently proposed role in the pathophysiology of glaucoma. This study was designed to shed light on the function of ANGPTL7 in obesity and its modulation by physical exercise as well as its potential association with lipid profile...

The AMP-activated protein kinase (AMPK) is a master regulator of metabolic homeostasis. It is activated by the upstream kinase LKB1 (liver kinase B1) when the AMP/ATP ratio is increased during starvation or heightened exercises. Based on reconstitution experiments using purified individual proteins, AMPK was demonstrated to be directly phosphorylated on its conserved residue Thr172 by LKB1, which was promoted by increased levels of AMP. However, recent studies have engendered a paradigm shift for how AMPK is activated inside the cell or animal tissues, unraveling that AXIN binds to LKB1 and tethers it to AMPK located on the surface of late endosome and lysosome (hereafter, only lysosome is discussed) in response to glucose starvation...

BACKGROUND: Exercises are important as an adjuvant for managing diabetes but due to fatigue and time constraints, individuals with diabetes may not engage in them. Jumping on a mini-trampoline referred to as rebound exercise is an aerobic activity used for exercise training benefits but only little research is available on its effects in diabetes. The purpose of this study was to determine the effect of mini-trampoline rebound exercise on insulin resistance and lipid profile in type 2 diabetics...

Very-long-chain-acyl-CoA-dehydrogenase deficiency is the most common disorder of mitochondrial long-chain fatty acid (LCFA) oxidation, with an incidence of 1:50,000-1:100,000 in newborns. Catabolic situations contribute to the aggravation of symptoms and induce severe metabolic derangement. Treatment for VLCAD-deficiency includes avoidance of fasting and a long-chain fat-restricted and fat-modified diet in which LCFAs are fully or partially replaced by medium-chain triglycerides (MCT). The aim of this work was to investigate the outcome and the effects of long-term treatment in a mouse model of VLCAD-deficiency...

In Taiwan, the prevalence of hyperlipidemia increased due to lifestyle and dietary habit changes. Low density lipoprotein cholesterol (LDL-C) and non-high density lipoprotein cholesterol (non-HDL-C) are all significant predicting factors of coronary artery disease in Taiwan. We recognized that lipid control is especially important in patients with existed atherosclerotic cardiovascular diseases (ASCVD), including coronary artery disease (CAD), ischemic stroke and peripheral arterial disease (PAD). Because the risk of ASCVD is high in patients with diabetes mellitus (DM), chronic kidney disease (CKD) and familial hypercholesterolemia (FH), lipid control is also necessary in these patients...

BACKGROUND: The number of bariatric procedures has exponentially increased in the past decade, as a result of the lack of successful clinical weight-loss interventions. The main reasons for the failure of clinical obesity management are: (1) anti-obesity medications are administered as monotherapies (or pre-combined drugs); (2) lack of combination between pharmacotherapy and non-pharmacological modalities; (3) short duration of pharmacotherapy for obesity; (4) lack of weight-loss maintenance strategies; (5) misunderstanding of the complex pathophysiology of obesity; and (6) underprescription of anti-obesity medications...
