Eggs are a source of cholesterol and choline and may impact plasma lipids and trimethylamine-N-oxide (TMAO) concentrations, which are biomarkers for cardiovascular disease (CVD) risk. Therefore, the effects of increasing egg intake (0, 1, 2, and 3 eggs/day) on these and other CVD risk biomarkers were evaluated in a young, healthy population. Thirty-eight subjects [19 men/19 women, 24.1 ± 2.2 years, body mass index (BMI) 24.3 ± 2.5 kg/m(2)] participated in this 14-week crossover intervention. Participants underwent a 2-week washout with no egg consumption, followed by intake of 1, 2, and 3 eggs/day for 4 weeks each...

BACKGROUND: HDL function may be more important than HDL concentration in determining risk for cardiovascular disease. In addition, HDL is a carrier of carotenoids and antioxidant enzymes, which protect HDL and LDL particles against oxidation. OBJECTIVE: The goal of this study was to determine the impact of consuming 0-3 eggs/d on LDL and HDL particle size, HDL function, and plasma antioxidants in a young, healthy population. METHODS: Thirty-eight healthy men and women [age 18-30 y, body mass index (in kg/m(2)) 18...

The cryopreservation of germ cells is a major tool for the propagation of animals with desired genetic traits. Although cryopreservation of spermatozoa in some animals is effective, its effectiveness is variable. For example, cryopreservation efficiency of buffalo bull spermatozoa remains very poor. In this study, we evaluated sperm DNA damage and ultrastructure in buffalo bull spermatozoa vitrified in the presence or absence of cholesterol-loaded cyclodextrins (CLC). Our results showed that cryopreserved buffalo spermatozoa had elevated levels of deteriorated plasma and mitochondrial membranes, which are the likely causes of DNA damage after vitrification...

Sterol 27-hydroxylase (CYP27A1) plays an important role in cholesterol homeostasis by degrading cholesterol to bile acids. Betaine can alleviate high-fat diet-induced hepatic cholesterol accumulation and maternal betaine treatment programs the hepatic expression of CYP27A1 in offspring. Excessive corticosterone (CORT) exposure causes hepatic cholesterol deposition in chickens, yet it remains unknown whether prenatal betaine modulates CORT-induced cholesterol accumulation in chicken liver later in life and whether it involves epigenetic gene regulation of CYP27A1...

Cholesterol-loaded cyclodextrin (CLC) is known to improve ram sperm cryosurvival. This study expands on previous research to: (1) determine the mechanism by which CLC improves ram sperm cryosurvival and (2) compare the efficiency of a novel, skim milk-based extender containing CLC to a traditional egg yolk-based extender. Hypothesis #1 was that CLC enhances membrane cholesterol content to increase the resistance of ram sperm to cold and osmotic stress, thereby improving cryosurvival. We first assessed the ability of fresh sperm treated with CLC to withstand cold shock...

Cholesterol is essential for neuronal development and brain function. Previously we reported that in ovo administration of betaine modulates hepatic cholesterol metabolism in the chicken, yet it remains unknown whether maternal betaine affects the cholesterol content and the expression of cholesterol metabolic genes in chicken hypothalamus. In this study, eggs were injected with saline or betaine at 2.5 mg/egg, and the hatchlings were raised under the same condition until 64 d of age. Maternal betaine significantly (P = 0...

The egg is a nutrient-dense food and contains a number of antioxidants. The consumption of eggs has been considered to improve the balance of diets, although its impact on serum cholesterol levels has been a matter of concern in many countries. Here, we conducted a pilot study to investigate whether daily additional consumption of an egg might affect serum lipid profiles and also antioxidant status in healthy subjects. Fourteen male subjects were provided with breakfasts including a boiled egg for 4 wk. At the end of intervention, serum concentrations of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were unchanged, despite the significant increase in the intake of dietary cholesterol...

Patients with non-alcoholic fatty liver disease (NAFLD) have an increased risk for progression to hepatocellular carcinoma in addition to comorbidities such as cardiovascular and serious metabolic diseases; however, the current therapeutic options are limited. Based on our previous report that omega-3 polyunsaturated fatty acids (n-3 PUFAs) can significantly ameliorate high fat diet (HFD)-induced NAFLD, we explored the therapeutic efficacy of n-3 PUFAs and N-IgY, which is a chicken egg yolk-derived IgY specific for the Niemann-Pick C1-Like 1 (NPC1L1) cholesterol transporter, on NAFLD in mice...

The incorporation of omega-3 polyunsaturated fatty acids (PUFA) in the egg is dependent on both the transfer efficiency of preformed dietary omega-3 fatty acids to the eggs as well as endogenous PUFA metabolism and deposition. Employing an experimental design consisting of 70 Lohmann LSL-Classic hens (n=10/treatment) in a 6-week feeding trial, we examined the impact of graded levels of either flaxseed oil (alpha-linolenic acid, ALA) or algal DHA (preformed docosahexaenoic acid, DHA), each supplying 0.20%, 0...

PURPOSE: The question of whether publication of selected clinical trials is temporally followed by changes in prescribing of adjunctive lipid-lowering medications was evaluated. METHODS: In this retrospective preanalysis and postanalysis, Veterans Health Administration (VHA) patients 18 years or older who received a new or renewed order for any lipid-lowering medication between April 2, 2004, and September 2, 2014, were included. This period was chosen based on the publication dates of three trials investigating the efficacy of nonstatin medications: Simvastatin with or without Ezetimibe in Familial Hypercholesterolemia (ENHANCE, April 3, 2008), Effects of Combination Lipid Therapy in Type 2 Diabetes Mellitus (ACCORD Lipid, March 14, 2010), and Niacin in Patients with Low HDL Cholesterol Levels Receiving Intensive Statin Therapy (AIM-HIGH, December 15, 2011)...

Western-type diets can induce obesity and related conditions such as dyslipidemia, insulin resistance and hepatic steatosis. We evaluated the effects of milk sphingomyelin (SM) and egg SM on diet-induced obesity, the development of hepatic steatosis and adipose inflammation in C57BL/6J mice fed a high-fat, cholesterol-enriched diet for 10 weeks. Mice were fed a low-fat diet (10% kcal from fat) (n=10), a high-fat diet (60% kcal from fat) (HFD, n=14) or a high-fat diet modified to contain either 0.1% (w/w) milk SM (n=14) or 0...

BACKGROUND: The potential of fermented buckwheat as feed additives was studied to increase L-carnitine and gamma-aminobutyric acid (GABA) in designer eggs. Buckwheat contains high levels of lysine, methionine, and glutamate, which are precursors for the synthesis of L-carnitine and GABA. Rhizopus oligosporus was used for the fermentation of buckwheat to produce L-carnitine and GABA that exert positive effects like enhanced metabolism, antioxidant activities, immunity, and blood pressure control...

Resveratrol belongs to the large group of biologically active polyphenol compounds, with several beneficial health effects including antioxidant activity, anti-inflammatory action, cardiovascular protection, neuroprotection, and cancer chemoprevention. In the present study, the possibility that the effects of resveratrol described above are caused by resveratrol membrane interactions and structural modifications of lipid bilayers is evaluated. In this context, it is possible that resveratrol interacts selectively with lipid domains present in biological membranes, thereby modulating the localization of the anchored proteins and controlling their intracellular cascades...

Psoralen in combination with ultraviolet A radiation (PUVA) is an FDA recommended therapy for clinical application in the management of severe recalcitrant psoriasis. Psoralen acts by intercalation of DNA and upon exposure to UV-A, it forms monoadducts which in turn induce apoptosis. Poor skin deposition, weak percutaneous permeability of psoralen and adverse effects of severe burning, blisters, pigmentation associated with conventional topical psoralen vehicles hinders the therapeutic efficacy and safety of topical PUVA...
