Erucic acid, eicosapentaenoic acid, and docosahexaenoic acid consumption affect hepatic steatosis in mice fed a western diet.

This study explored whether erucic acid (EA) intake at levels typical of fatty fish consumption aggravates non-alcoholic fatty liver disease (NAFLD) or affects the benefits of marine n-3 polyunsaturated fatty acids (PUFAs). N-3 PUFAs, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), enhance beta-oxidation and suppress lipogenesis, reducing hepatic triglyceride accumulation. Sixty-six C57BL/6N mice were fed a chow diet, western diet (WD), or WDs supplemented with EA alone or combined with EPA or DHA for 13 weeks. Dietary EA, EPA, and DHA levels matched average intake fro

Effect of the early introduction of trophic donor human breast milk on the preservation of postoperative gut functions in a fasting animal model.

Dietary restrictions, such as avoiding oral intake until postoperative ileus resolves, can result in negative nitrogen balance, weakened immune function, and impaired digestive system performance. This study investigates the efficacy of donor human breast milk (HM) in early trophic enteral feeding and its impact on gut functions during prolonged postoperative fasting in an animal model. Male Wistar rats were deprived of food for 48 hours with free water access. After a complete ileal transection and an end-to-end intestinal anastomosis, the rats were divided into three groups: prolonged fastin

Olfactory bulbectomy-induced impairment of lipid utilization leads to abnormal glucose metabolism in mice.

Increased lipid utilization after food odor perception is a recently identified Pavlovian cephalic phase response in fasted mice that serves to prevent diet-induced glucose intolerance. However, the impact of olfactory dysfunction on metabolic functions remains unclear. Since olfactory bulbectomized (OBX) rodents have been used as a model of irreversible complete anosmia, we investigated whether glucose, lipid, and energy metabolism change over time in OBX mice fed a normal chow diet (NCD) or high-fat diet (HFD). OBX caused constant hyperactivity and triphasic temporal changes in lipid and glu

Cardiovascular Health and Diet Quality among Vegetarians, Vegans and Omnivores: Insights from a Large Urban Population in Poland.

Background/Objectives: Dietary habits are among the most significant determinants of health. The aim of this study was to assess the nutritional quality and cardiovascular profiles of individuals following plant-based diet. Methods: The study population comprised 199 individuals (136 women, 63 men; mean age 33.9  ±  8.9 years) including vegans (VG; n = 50), vegetarians (VN; n = 101) and omnivores (OV; n = 48). In this analysis the following procedures were assessed: a questionnaire interview, anthropometric and blood pressure measurements, and a blood sample collection. Dietary patterns were e

Seasonal fluctuations in BDNF regulate hibernation and torpor in golden-mantled ground squirrels.

Aphagic hibernators such as the golden-mantled ground squirrel (GMGS; Callospermophilus lateralis) can fast for months and exhibit profound seasonal fluctuations in body weight, food intake, and behavior. Brain-derived neurotrophic factor (BDNF) regulates cellular and systemic metabolism via mechanisms that are conserved across mammalian species. In this study, we characterized regional changes in BDNF with hibernation, hypothermia, and seasonal cycle in GMGS. Analysis of BDNF protein concentrations by ELISA revealed overlapping seasonal patterns in the hippocampus and hypothalamus, where BDNF

Stealthy progression of type 2 diabetes mellitus due to impaired ketone production in an adult patient with multiple acyl-CoA dehydrogenase deficiency.

BACKGROUND: Multiple acyl-CoA dehydrogenase deficiency (MADD) is an inherited metabolic disorder caused by biallelic pathogenic variants in genes related to the flavoprotein complex. Dysfunction of the complex leads to impaired fatty acid oxidation and ketone body production which can cause hypoketotic hypoglycemia with prolonged fasting. Patients with fatty acid oxidation disorders (FAODs) such as MADD are treated primarily with a dietary regimen consisting of high-carbohydrate foods and avoidance of prolonged fasting. However, information on the long-term sequelae associated with this diet h

The role of gastric ultrasound in anaesthesia for emergency surgery: A review and clinical guidance.

BACKGROUND: The timing and technique of anaesthesia are challenging in patients with a history of recent food intake. The presence of gastric contents increases the risk of aspiration, potentially resulting in acute lung injury, pneumonia, or death. Delayed gastric emptying complicates the estimation of aspiration risk. Surprisingly, there are no fasting guidelines for emergency surgery. Point-of-care gastric ultrasound is a time-efficient, cost-efficient and accurate bedside tool with which to estimate residual gastric content and to guide decision-making in airway management and timing of ge

Obesity-related parameters in carriers of some BDNF genetic variants may depend on daily dietary macronutrients intake.

Some common single-nucleotide polymorphisms of the brain-derived neurotrophic factor (BDNF) gene have been associated not only with the neurodegenerative diseases but also with some eating disorders. The aim of this study was to assess the possible differences in the obesity-related and glucose metabolism parameters between some BDNF genotypes', that may depend on the daily energy and macronutrients intake. In 484 adult participants we performed the anthropometric measurements, body composition analysis, and body fat distribution. The daily dietary intake was assessed using the 3-day food inta

The Urinary Excretion of Magnesium as an Effective Magnesium Deficiency State Indicator: A Controlled Intervention Trial.

With the western influence in our diets, food consumption has changed, and our magnesium (Mg) intake is no longer optimal. Serum Mg (S-Mg) level is currently used as an indicator of Mg deficiency and is strictly regulated via compensatory mechanisms. It is believed that a 24-h urine collection can be used to evaluate potential Mg deficiency. This study aimed to assess whether Mg deficiency state as found in urine Mg (U-Mg) excretion and improving such deficiency with a diet that meets the Recommended Dietary Allowances (RDAs) of Mg for 15 d. Healthy Japanese women were recruited for Study 1 (n

Sulfur Amino Acid Supplementation Abrogates Protective Effects of Caloric Restriction for Enhancing Bone Marrow Regrowth Following Ionizing Radiation.

Radiation therapy damages and depletes total bone marrow (BM) cellularity, compromising safety and limiting effective dosing. Aging also strains total BM and BM hematopoietic stem and progenitor cell (HSPC) renewal and function, resulting in multi-system defects. Interventions that preserve BM and BM HSPC homeostasis thus have potential clinical significance. Here, we report that 50% calorie restriction (CR) for 7-days or fasting for 3-days prior to irradiation improved mouse BM regrowth in the days and weeks post irradiation. Specifically, one week of 50% CR ameliorated loss of total BM cellu

The Effect of Gum Arabic (Acacia Senegal) on Cardiovascular Risk Factors and Gastrointestinal Symptoms in Adults at Risk of Metabolic Syndrome: A Randomized Clinical Trial.

Gum Arabic (GA) is a widely-used additive in food processing, but is also historically used in a number of traditional therapies. It has been shown to have a broad range of health benefits, particularly in improving important cardiovascular risk indicators. Metabolic syndrome and its associated cardiac outcomes are a significant burden on modern healthcare systems, and complementary interventions to aid in its management are required. We aimed to examine the effect of GA on those with, or at risk of, metabolic syndrome to identify an effect on improving important disease parameters related to

High-fat diet negatively impacts both metabolic and behavioral health in outbred heterogeneous stock rats.

Obesity is influenced by genetics and diet and has wide ranging comorbidities, including anxiety and depressive disorders. Outbred heterogeneous stock (HS) rats are used for fine-genetic mapping of complex traits and may be useful for understanding gene by diet interactions. In this study, HS rats were fed diets containing 60% kcal from fat (high-fat diet, HFD) or 10% kcal from fat (low-fat diet, LFD) and tested for metabolic (study 1) and behavioral (study 2) outcomes. In study 1, we measured glucose tolerance, fasting glucose and insulin, fat pad weights and despair-like behavior in the forc

2-Methoxyestradiol ameliorates metabolic syndrome-induced hypertension and catechol-O-methyltransferase inhibited expression and activity in rats.

Metabolic syndrome (MetS) is a common disorder that is associated with hypertension and poses a significant cardiovascular risk. Deactivation of extra-neuronal norepinephrine is mediated by catechol-O-methyltransferase (COMT). Endogenous 2-methoxyestradiol (2ME) is a product of COMT activity. The current study investigated the impact of 2ME on MetS-induced hypertension and the possible alterations in COMT expression and activity in rats. Animals were randomly divided into 4 groups. Group 1 received drinking water and standard food pellets. Groups 2, 3 and 4 were subjected to experimental induc

Endogenous Oxytocin Levels in Relation to Food Intake, Menstrual Phase, and Age in Females.

CONTEXT: Oxytocin regulates a range of physiological processes including eating behavior and oxytocin administration reduces caloric intake in males. There are few data on oxytocin and eating behavior in healthy females or on the response of endogenous oxytocin to food intake and its relationship to appetite in humans. OBJECTIVES: To determine the postprandial pattern of oxytocin levels, the relationship between oxytocin and appetite, and the impact of menstrual cycle phase and age on oxytocin levels in females. DESIGN: Cross-sectional. SETTING: Clinical research center. PARTICIPANTS: Fift

BACKGROUND: Type 2 diabetes has a high spread and growing process. Using appropriate food diets is among therapeutic approaches has been applied for diabetic patients. Soya utilization has shown effective results in controlling metabolic abnormalities of these patients. The aim of this study is to investigate the effects of soy nut on glycemic conditions, blood pressure, lipid profile, antioxidant effects and vascular endothelial function of these patients. METHODS: 70 patients with type 2 diabetes were randomly divided into two groups of the test (35 people) and control (35 people). The pati

Gastric Sleeve Surgery Alleviates Obesity-Associated Insulin Resistance and Suppresses Endoplasmic Reticulum Stress in Adipose Tissue of db/db Mice.

OBJECTIVE: The aims of this study were to evaluate the effects of gastric sleeve surgery on diabetes remission in db/db mice as well as to determine the underlying mechanisms. METHODS: Thirty spontaneously obese, diabetic mice (C57BL/Ksj-db/db) were randomly divided into three groups: sleeve gastrectomy group, sham-operated group, and control db/db group. Ten db/m lean mice were used as nondiabetic littermate controls. All mice were sacrificed on day 28. The fasting plasma glucose, serum insulin, lipid profile, and oral glucose tolerance were measured pre- and postoperatively. Inflammatory cy

DP1 receptor agonist, BW245C inhibits diet-induced obesity in ApoE-/- mice.

BACKGROUND/OBJECTIVE: Lipocalin Prostaglandin D2 synthase (LPGDS) contributes to the production of PGD2, which has been associated with adipogenesis. In this study, we aimed to investigate the role of PGD2 on obesity through its DP1 and DP2 receptor signaling using intraperitoneal injection of their respective agonists and antagonists. METHODS: ApoE-/- mice were divided into five groups: vehicle control (n=5), DP1 receptor agonist (n=5), DP1 receptor antagonist (n=5), DP2 receptor agonist (n=5), and DP2 receptor antagonist (n=5), and the study was carried out for 10 weeks. RESULTS: Despite b

Over-expression of Follistatin-like 3 attenuates fat accumulation and improves insulin sensitivity in mice.

OBJECTIVE: Follistatin-like 3 (fstl3), a natural inhibitor of members of the TGF-β family, increases during resistance training in human plasma. Fstl3 primarily binds myostatin and activin A, and thereby inhibits their functions. We hypothesize that blocking myostatin and activin A signalling through systemic fstl3 over-expression protects against diet-induced obesity and insulin resistance. METHODS: Fstl3 was over-expressed by DNA electrotransfer in tibialis anterior, quadriceps and gastrocnemius muscles in female C57BL/C mice, and the mice were subsequently randomized to chow or high-fat fe

Activation of anorexigenic pro-opiomelanocortin neurones during refeeding is independent of vagal and brainstem inputs.

After fasting, satiety is observed within 2 h after reintroducing food, accompanied by activation of anorexigenic, pro-opiomelanocortin (POMC)-synthesising neurones in the arcuate nucleus (ARC), indicative of the critical role that α-melanocyte-stimulating hormone has in the regulation of meal size during refeeding. To determine whether refeeding-induced activation of POMC neurones in the arcuate is dependent upon the vagus nerve and/or ascending brainstem pathways, bilateral subdiaphragmatic vagotomy or transection of the afferent brainstem input to one side of the ARC was performed.
