Intake of S-Methylmethionine Alters Glucose Metabolism and Hepatic Gene Expression in C57BL/6J High-Fat-Fed Mice.

A diet containing foods that are sources of S-methylmethionine (SMM), and its use as a dietary supplement, have demonstrated beneficial health effects. Thus, the objective of this work was to evaluate the inclusion of SMM as a dietary supplement in C57BL/6J high-fat-fed mice to verify whether this compound alone would be responsible for these positive effects. Mice were divided into three groups: LF (low-fat diet), HF (high-fat diet), and HF+SMM (high-fat diet plus SMM), and maintained for 10 weeks with water and food provided ad libitum.

Phlegmonous gastritis: Review of the pathophysiology.

Phlegmonous gastritis is a rare infection of the gastric wall. Clinical presentation of phlegmonous gastritis is generally non-specific and includes epigastric pain, nausea, vomiting and fever. The infection results from a transmural infection of the stomach.

Diet composition influences the effect of high fat diets on bone in growing male mice.

The effect of diet-induced obesity on bone in rodents is variable, with bone mass increases, decreases, and no impact reported. The goal of this study was to evaluate whether the composition of obesogenic diet may influence bone independent of its effect on body weight. As proof-of-principle, we used a mouse model to compare the skeletal effects of a commonly used high fat 'Western' diet and a modified high fat diet.

Perspective: Challenges and Future Directions in Clinical Research with Nuts and Berries.

Consumption of nuts and berries are considered part of a healthy eating pattern. Nuts and berries contain a complex nutrient profile consisting of essential vitamins and minerals, fiber, polyunsaturated fatty acids, and phenolics in quantities that improve physiological outcomes. The spectrum of health outcomes that may be impacted by the consumptions of nuts and berries includes cardiovascular, gut microbiome, and cognitive, among others.

Intake of an enological oak tannin powder alters hepatic gene express patterns indicative of a reduction of inflammation in male mice fed an obesogenic diet.

Hydrolysable tannins, mainly gallotannins and ellagitannins, either extracted directly from oak or as a part of lyophilized extracts from finished wine, have been associated with antioxidant and anti-inflammatory properties that may benefit human health. In this work we hypothesized that a commercially available oak tannin powder provided to C57BL/6J male mice fed a western-style obesogenic diet for 10 weeks would significantly alter hepatic gene expression patterns as determined by RNA sequencing. Over two-thousand genes were uniquely expressed between three different diet groups.

Consumption of Antioxidant-Rich "Cerrado" Cashew Pseudofruit Affects Hepatic Gene Expression in Obese C57BL/6J High Fat-Fed Mice.

The pseudofruit of Rizzini, "Cerrado" cashew pulp, has been described as rich in flavonoids, phenolic compounds, and vitamin C. The objective of this work was to evaluate the beneficial health effects seen with the addition of "Cerrado" cashew pulp (CP) to an obesogenic high fat diet provided to C57BL/6J male mice. In week 9, the HF-fed group had a significantly higher baseline glucose concentration than the LF- or HF+CP-fed groups.

Intake of Watermelon and Watermelon Byproducts in Male Mice Fed a Western-Style Obesogenic Diet Alters Hepatic Gene Expression Patterns, as Determined by RNA Sequencing.

Background: Consumption of watermelon has been associated with beneficial effects on metabolism, including reductions in systolic blood pressure, improved fasting blood glucose levels, and changes in hepatic metabolite accumulation.

Objectives: In the present study, we investigated the impact of consumption of watermelon flesh (WF), watermelon rind (WR), and watermelon skin (WS) on hepatic gene expression patterns in an obesogenic mouse model.

Methods: Hepatic RNA was isolated and RNA sequencing was performed following a 10-week feeding trial during which C57BL/6 J mice were provided either a low-fat diet (LF), high-fat diet (HF; controls), or HF plus either WS, WR, or WF.

Metabolic Syndrome Is Reduced in C57BL/6J Mice Fed High-Fat Diets Supplemented with Oak Tannins.

Background: Wine aged in oak barrels will incorporate polyphenols inherent in the staves, suggesting that wine stored in these wooden containers will introduce oak compounds into the human body after consumption.

Objective: The purpose of the present study is to test whether consumption of these oak compounds could favorably influence metabolism in mice fed an obesogenic diet.

Methods: C57BL/6  male mice ( = 8) were fed diets for 10 wk as follows: low-fat (LF), high-fat (HF), and HF containing 0.

Intake of Watermelon or Its Byproducts Alters Glucose Metabolism, the Microbiome, and Hepatic Proinflammatory Metabolites in High-Fat-Fed Male C57BL/6 J Mice.

Background: Watermelon intake has demonstrated effects on blood pressure regulation along with other health benefits.

Objective: We hypothesized that intake of whole watermelon and products made from watermelon rind (WR) and watermelon skin (WS) would remediate metabolic complications in C57BL/6 J male mice fed a diet modeling a Western-style diet.

Methods: Ten-week-old male C57BL/6 J mice were provided either a low-fat (LF) diet [10% fat (by energy), 8% sucrose (by energy) and no added cholesterol], a high-fat (HF) diet [45% fat (by energy), 20% kcal sucrose (by energy), and 1% (w/w) cholesterol], or an HF diet plus WS, WR, or watermelon flesh (WF) for 10 wk.

Consuming Diet Supplemented with Either Red Wheat Bran or Soy Extract Changes Glucose and Insulin Levels in Female Obese Zucker Rats.

Type 2 diabetes mellitus is characterized by the inability to regulate blood glucose levels due to insulin resistance, resulting in hyperglycemia and hyperinsulinemia. Research has shown that consuming soy and fiber may protect against type 2 diabetes mellitus. We performed a study to determine whether supplementing diet with soy extract (0.

Genistein and daidzein decrease food intake and body weight gain in mice, and alter LXR signaling in vivo and in vitro.

The study is designed to determine whether consumption of the soy isoflavones, genistein and daidzein, differentially influence metabolic syndrome, and to further investigate the involvement of Liver X Receptor (LXR) regulation. C57BL/6J mice were fed diets as follows: low fat diet (LF), western-style diet (WD), and WD containing 0.16% (w/w) of genistein (WD + G) or daidzein (WD + D) for 10 weeks.

Consumption of a single serving of red raspberries per day reduces metabolic syndrome parameters in high-fat fed mice.

Using an animal model for diet-induced metabolic disease, we have shown previously that the addition of raspberry juice concentrate (RJC) and raspberry puree concentrate (RPC) at a level of 10% of kcal, equivalent to four servings per day, to an obesogenic high-fat, western-style diet (HF) significantly reduced body weight gain, serum resistin levels, and altered the expression of hepatic genes related to lipid metabolism and oxidative stress. This study was designed to examine the effect of a lower level of RJC or RPC consumption, at a level representing a single serving of food per day (2.5% of kcal).

Gene Expression Patterns Are Altered in Athymic Mice and Metabolic Syndrome Factors Are Reduced in C57BL/6J Mice Fed High-Fat Diets Supplemented with Soy Isoflavones.

Soy isoflavones exert beneficial health effects; however, their potential to ameliorate conditions associated with the metabolic syndrome (MetS) has not been studied in detail. In vitro and in vivo models were used to determine the effect of isoflavones on lipid metabolism, inflammation, and oxidative stress. In nude mice, consumption of Novasoy (NS) increased cholesterol and lipid metabolism gene expression, including Scd-1 (27.

Improvements in Metabolic Health with Consumption of Ellagic Acid and Subsequent Conversion into Urolithins: Evidence and Mechanisms.

Ellagic acid (EA) is a naturally occurring polyphenol found in some fruits and nuts, including berries, pomegranates, grapes, and walnuts. EA has been investigated extensively because of its antiproliferative action in some cancers, along with its anti-inflammatory effects. A growing body of evidence suggests that the intake of EA is effective in attenuating obesity and ameliorating obesity-mediated metabolic complications, such as insulin resistance, type 2 diabetes, nonalcoholic fatty liver disease, and atherosclerosis.

Consumption of Walnuts in Combination with Other Whole Foods Produces Physiologic, Metabolic, and Gene Expression Changes in Obese C57BL/6J High-Fat-Fed Male Mice.

Background: Although a reductionist approach has sought to understand the roles of individual nutrients and biochemicals in foods, it has become apparent that there can be differences when studying food components in isolation or within the natural matrix of a whole food.

Objective: The objective of this study was to determine the ability of whole-food intake to modulate the development of obesity and other metabolic dysfunction in mice fed a high-fat (HF), Western-style obesogenic diet. To test the hypothesis that an n-3 (ω-3) polyunsaturated fatty acid-rich food could synergize with other, largely polyphenol-rich foods by producing greater reductions in metabolic disease conditions, the intake of English walnuts was evaluated in combination with 9 other whole foods.

Consumption of Quercetin and Quercetin-Containing Apple and Cherry Extracts Affects Blood Glucose Concentration, Hepatic Metabolism, and Gene Expression Patterns in Obese C57BL/6J High Fat-Fed Mice.

Background: Intake of polyphenols and polyphenol-rich fruit extracts has been shown to reduce markers of inflammation, diabetes, and hepatic complications that result from the consumption of a high-fat (HF) diet.

Objective: The objective of this study was to determine whether mice fed polyphenol-rich apple peel extract (AE), cherry extract (CE), and quercetin, a phytochemical abundant in fruits including apples and cherries, would modulate the harmful effects of adiposity on blood glucose regulation, endocrine concentrations, and hepatic metabolism in HF-fed C57BL/6J male mice.

Methods: Groups of 8-wk-old mice (n = 8 each) were fed 5 diets for 10 wk, including low-fat (LF; 10% of total energy) and HF (60% of total energy) control diets and 3 HF diets containing polyphenol-rich AE, CE, and quercetin (0.

Ellagic acid modulates lipid accumulation in primary human adipocytes and human hepatoma Huh7 cells via discrete mechanisms.

Previously, we have reported that consumption of a muscadine grape phytochemical powder (MGP) decreased lipid accumulation in high-fat fed mice. The aim of this study was to identify the responsible polyphenolic constituents and elucidate the underlying mechanisms. In mice, MGP supplementation significantly reduced visceral fat mass as well as adipocyte size.

Sleep problems and their relationship to cognitive and behavioral outcomes in young children with traumatic brain injury.

This study examined the effect of traumatic brain injury (TBI) in young children on sleep problems and the relationship of sleep problems to neuropsychological and psychosocial functioning. Participants were drawn from an ongoing longitudinal study of injury in young children recruited from 3 to 6 years of age. They constituted three groups: orthopedic injury (OI; n=92), complicated mild/moderate TBI (mTBI; n=55); and severe TBI (sTBI; n=20).

Management of transradial access for coronary angiography.

The transradial approach for percutaneous coronary intervention and angiography has been shown to be a safe and effective alternative to the traditional transfemoral approach. Used extensively throughout Europe for the past 15 years, this technique has recently gained widespread popularity throughout the United States. Lower direct costs, fewer vascular complications, better patient acceptance, and earlier ambulation are some of the direct benefits from using radial access.

Muscadine grape (Vitis rotundifolia) and wine phytochemicals prevented obesity-associated metabolic complications in C57BL/6J mice.

The objective of this study was to determine the effects of muscadine grape or wine (cv. Noble) phytochemicals on obesity and associated metabolic complications. Muscadine grape or wine phytochemicals were extracted using Amberlite FPX66 resin.

Daidzein and the daidzein metabolite, equol, enhance adipocyte differentiation and PPARgamma transcriptional activity.

Dietary soy isoflavones have been shown to favorably alter the metabolic phenotypes associated with Type 2 diabetes. However, the identification of direct targets and the underlying molecular mechanisms by which soy isoflaovones exert antidiabetic effects remain elusive. Since the insulin-sensitizing effects of thiazolidinediones, antidiabetic drugs, are mediated through activation of peroxisome proliferators-activated receptor gamma (PPARgamma), we examined the effects of daidzein and the daidzein metabolite, equol, on adipocyte differentiation and PPARgamma activation.

Human CYP3A4 and murine Cyp3A11 are regulated by equol and genistein via the pregnane X receptor in a species-specific manner.

Pregnane X receptor (PXR) is an important component of the body's adaptive defense system responsible for the elimination of various toxic xenobiotics. PXR activation by endogenous and exogenous chemicals, including steroids, antibiotics, bile acids, and herbal compounds, results in induction of drug metabolism. We investigated the ability of the isoflavones genistein, daidzein, and the daidzein metabolite equol to activate human and mouse PXR in vitro using cell-based transient transfection studies and primary hepatocytes and in vivo in a mouse model.

Maternal depression and trait anger as risk factors for escalated physical discipline.

To test the hypothesized anger-mediated relation between maternal depression and escalation of physical discipline, 122 economically disadvantaged mothers were assessed for current and lifetime diagnoses of depression using the Current Depressive Episode, Past Depression, and Dysthymia sections of the Structured Clinical Interview for DSM-IV (SCID) and a measure of current depressive symptoms, the Beck Depression Inventory-Second Edition (BDI-II). Escalation of physical discipline was assessed using a video analog parenting task; maternal anger not specific to discipline was assessed using the Spielberger Trait Anger Expression Inventory. Reports of anger were associated with the diagnosis of depression and depressive symptoms.

Human and murine hepatic sterol-12-alpha-hydroxylase and other xenobiotic metabolism mRNA are upregulated by soy isoflavones.

The transport and metabolism of xenobiotics is controlled by the drug transporters and drug-metabolizing enzymes in the liver and small intestine. Expression of these genes is 1 factor affecting the half-life of drugs and xenobiotics. Isoflavone-containing soyfood products and supplements are promoted to treat several different health conditions, including improvement of blood lipid profiles.

Soy protein and isoflavones influence adiposity and development of metabolic syndrome in the obese male ZDF rat.

Background/aims: Previously, we demonstrated that soy protein ameliorates the diabetic phenotype in several rodent models of obesity and metabolic syndrome (MS). This study was designed to further elucidate factors related to adiposity, glycemic control, and renal function in male Zucker Diabetic Fatty (ZDF/Lepr(fa)) rats.

Methods: Animals were randomly assigned to one of four diets: control, casein (C); low isoflavone (LIS) soy protein; high isoflavone (HIS) soy protein, or casein + rosiglitazone (CR) for 11 weeks.
