BACKGROUND AND AIMS: Atherosclerosis is a lipid-driven chronic inflammatory disorder of the arteries, and monocytes and macrophages play a central role in this process. Within the atherosclerotic lesion, macrophages can scavenge modified lipids and become the so-called foam cells. We previously reported that the epigenetic enzyme Kdm6b (also known as Jmjd3) controls the pro-fibrotic transcriptional profile of peritoneal foam cells. Given the importance of these cells in atherosclerosis, we now studied the effect of myeloid Kdm6b on disease progression...

This study evaluated the effects of supplementing chitooligosaccharide (COS) in low fish meal (FM) diets on growth, immune response, intestine and hepatopancrease histology, and expression of inflammatory and immune-related genes in Pacific white shrimp (Litopenaeus vannamei). A basal diet was formulated using FM and soybean meal (SM) as primary protein sources and considered as a high FM (HFM) diet, then a low FM (LFM) diet was prepared by substituting 50% of FM with SM and supplemented with 0, 3, 6, 9, 12 or 15 g COS kg-1 diet (LFM, COS3, COS6, COS9, COS12 and COS15 diets)...

Hydrogen sulfide (H2 S) is a novel gasotransmitter produced endogenously in mammalian cells, which works by mediating diverse physiological functions. An imbalance in H2 S metabolism is associated with defective bone homeostasis. However, it is unknown whether H2 S plays any epigenetic role in bone loss induced by hyperhomocysteinemia (HHcy). We demonstrate that diet-induced HHcy, a mouse model of metabolite induced osteoporosis, alters homocysteine metabolism by decreasing plasma levels of H2 S. Treatment with NaHS (H2 S donor), normalizes the plasma level of H2 S and further alleviates HHcy induced trabecular bone loss and mechanical strength...

Lathyrism is a disease caused by excessive consumption of grass pea, Lathyrus sativus especially under conditions of severe drought. Grass pea contains 3-N-oxalyl-L-2, 3-diaminopropanoic acid (β-ODAP) a putative neurotoxin which acts through excitatory mechanism causing Neurolathyrism. Due to awareness of the disease, availability of food and levels of consumption of L. sativus there is reduction in lathyrism cases where higher consumption of L. sativus is reported in India. The present study was undertaken with the objective to assess the current scenario of consumption of L...

Medium-chain triglycerides (MCT) are emerging as unique dietary supplements potentially relevant to improve brain dysfunctions. MCT are converted into ketones and free medium chain fatty acids that, in the brain, are highly effective energy sources to mitochondria and potentially less harmful than glucose metabolism to neurons. Given the recently established link between mitochondrial dysfunction and high anxiety and depression, we set this study to investigate the effectiveness of an MCT-enriched diet to ameliorate anxiety- and depression-related behaviors in rats...

The aim of this randomized, double-blinded, placebo-controlled study was to evaluate if downregulation of the inflammatory response due to ingestion of high levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) can slow down gingivitis development, and thus delay the progression of periodontal disease (PD) in dogs. To this aim, 44 client-owned adult dogs (>1 and <8 years old) with naturally occurring PD (stages 1 and 2) were submitted to a plaque, gingivitis and calculus scoring followed by a dental cleaning procedure and collection of blood samples...

Insulin resistance (IR) is a hallmark of type 2 diabetes mellitus (T2DM). This study aimed to explore the effects of rapamycin, a specific inhibitor of kinase mammalian target of rapamycin (mTOR), on IR in T2DM rats, and to validate whether the underlying mechanism was associated with autophagy. In this study, the model of T2DM rats was established by feeding the animals with a high-fat diet (HFD) and intraperitoneal injection of streptozotocin (STZ). Diabetic rats were randomly divided into model of T2DM control group (DM-C, n=15), metformin group (DM-M, n=15), rapamycin group (DM-Rapa, n=15), 3-methyladenine (3-MA) group (DM-3-MA, n=15), and rapamycin+3-MA group (DM-Rapa-3-MA, n=15)...

We report the genetic analysis of a "humanized" hyperlipidemic mouse model for progressive nonalcoholic steatohepatitis (NASH) and fibrosis. Mice carrying transgenes for human APOE*3-Leiden and CETP and fed a "Western" diet were studied on the genetic backgrounds of over 100 inbred mouse strains. The mice developed hepatic inflammation and fibrosis that was highly dependent on genetic background, with vast differences in the degree of fibrosis. Histological analysis showed features characteristic of human NASH, including macrovesicular steatosis, hepatocellular ballooning, inflammatory foci and pericellular collagen deposition...

OBJECTIVES: Obesity is associated with periodontitis, but the mechanisms underlying this association have yet to be unraveled. The present investigation was to evaluate a common rat model, in which obesity is induced by high-fat, high-sucrose diet (HFSD), for its applicability in periodontal research. MATERIALS AND METHODS: Ten male Wistar rats were fed a 3-month HFSD along with a matching control group. Afterwards, the body weight, adipocyte morphology, leptin and adiponectin levels in adipose tissue, gingiva, and serum as well as the serum levels of triglyceride, cholesterol, and glucose were analyzed...

Type II Diabetes (T2DM) negatively alters baseline tendon function, including decreased range of motion and mechanical properties; however, the biological mechanisms that promote diabetic tendinopathy are unknown. To facilitate identification of therapeutic targets we developed a novel murine model of diabetic tendinopathy. Mice fed a High Fat Diet (HFD) developed diet induced obesity and T2DM and demonstrated progressive impairments in tendon gliding function and mechanical properties, relative to mice fed a Low Fat Diet (LFD)...

PURPOSE: SMARCB1 encodes a subunit of the SWI/SNF complex involved in chromatin remodeling. Pathogenic variants (PV) in this gene can give rise to three conditions. Heterozygous loss-of-function germline PV cause rhabdoid tumor predisposition syndrome and schwannomatosis. Missense PV and small in-frame deletions in exons 8 and 9 result in Coffin-Siris syndrome, which is characterized by intellectual disability (ID), coarse facial features, and fifth digit anomalies. METHODS: By a gene matching approach, individuals with a similar SMARCB1 PV were identified...

Ghrelin is a unique fatty acid-modified peptide hormone produced in the stomach and has important roles in energy homeostasis and gastrointestinal motility. However, the medium-chain fatty acid source for ghrelin acyl-modification is not known. We found that a fat-free diet and the removal of intestinal microbiota did not decrease acyl-ghrelin production in the stomach or plasma acyl-ghrelin levels in mice. RT-PCR analysis showed that genes involving fatty acid synthesis, metabolism, and transport were expressed in pancreas-derived ghrelinoma (PG-1) cells...

: media-1vid110.1542/5778442247001PEDS-VA_2017-4085 Video Abstract BACKGROUND AND OBJECTIVES: Shorter sleep duration is associated with childhood obesity. Few studies measure sleep quantity and quality objectively or examine cardiometabolic biomarkers other than obesity. METHODS: This cross-sectional study of 829 adolescents derived sleep duration, efficiency and moderate-to-vigorous physical activity from >5 days of wrist actigraphy recording for >10 hours/day. The main outcome was a metabolic risk score (mean of 5 sex-specific z-scores for waist circumference, systolic blood pressure, high-density lipoprotein cholesterol scaled inversely, and log-transformed triglycerides and homeostatic model assessment of insulin resistance), for which higher scores indicate greater metabolic risk...

We previously discovered that oral treatment with AC261066, a synthetic selective agonist for the retinoic acid β2-receptor (RARβ2), decreases oxidative stress in the liver, pancreas, and kidney of mice fed a high-fat diet (HFD). Since hyperlipidemic states are causally associated with myocardial ischemia and oxidative stress, we have now investigated the effects of AC261066 in an ex-vivo ischemia/reperfusion (I/R) injury model in hearts of two prototypic dysmetabolic mice. We found that a 6-week oral treatment with AC261066 in both genetically hypercholesterolemic (ApoE-/-) and obese (HFD-fed) wild-type mice exerts protective effects when their hearts are subsequently subjected to I/R ex vivo in the absence of added drug...

Dry period management of the dairy cow focuses on maximising milk production during the subsequent lactation but may include procedures that negatively affect dry cow health and welfare. A survey of dairy farmers in the UK was conducted to investigate dry cow management procedures. The questionnaire was completed by 148 farmers. Most farms (84 per cent) kept dry cows in dynamic social groups. The median length of the dry period was 56 days, and 83 per cent of farms stopped milking abruptly, regardless of milk production level at dry-off...

Abnormal maternal lipid profiles, a hallmark of increased maternal adiposity, are associated with pregnancy complications such as preeclampsia and gestational diabetes, and offspring long-term metabolic health is impacted as the consequence of altered fetal growth, physiology and often iatrogenic prematurity. The metabolic changes associated with maternal obesity and/or the consumption of a high-fat diet effecting maternal lipid profiles and metabolism have also been documented to specifically affect placental function and may underlie changes in fetal development and life course disease risk...

BACKGROUND: Atherosclerosis is a slowly progressing, chronic multifactorial disease characterized by the accumulation of lipids, inflammatory cells, and fibrous tissue that drives to the formation of asymmetric focal thickenings in the tunica intima of large and mid-sized arteries. Despite the high therapeutic potential of ApoA-1 proteins, the purification and delivery into the disordered organisms of these drugs is still limited by low efficiency in these processes. METHODS AND RESULTS: We report here a novel production and delivery system of anti-atherogenic APOA-1Milano muteins (APOA-1M) by means of genetically modified rice plants...

The present study aims to test if the environmental conditions prevailing during the growing period can determine the physiological profiles of specimens differentiated as fast (F) or slow (S) growers in the mussel Mytilus galloprovincialis. We reared mussel spats in the laboratory under two different conditions. In Treatment I (continuous feeding during discontinuous immersion), two mussel groups were submitted to a daily air exposure of 8 h and fed continuously during immersion-time, with either high-quality food dosed below the pseudofaeces threshold (BP group) or low organic content food dosed above the pseudofaeces threshold (AP group)...

Nutrition is a modifiable factor affecting the quality of life and independence of older people. The physiological, psychological and social changes during aging affect their dietary choices. Many older adults have inadequate energy and protein intake. Carbohydrate intake and intake of total lipids, in terms of contribution to total energy intake, generally are within the recommended levels, but a decline in overall energy intake as well as the limited variety of micronutrient-dense foods that older people tend to consume result in an inadequate intake of several micronutrients...
