Docosahexaenoic acid (DHA) and arachidonic acid (AA) are the major polyunsaturated fatty acids (PUFA) in the neuronal membrane. Most DHA and AA accumulation in the brain occurs during the perinatal period via placenta and milk. This study examined whether maternal brain levels of DHA and AA are depleted during pregnancy ...

Traumatic brain injury (TBI) is a major public health issue affecting 1.4 million Americans each year, of which approximately 50,000 die annually. High-fat sucrose (HFS) diets are another public health issue which can lead to obesity, hypertension, and many other debilitating disorders. These two disorders combined can lead to more ...

Background:  Protein phosphatase PP2A dephosphorylates phosphorylated tau (P-tau) and neurofilaments (pNFs). PP2A is S-adenosylmethionine (SAM)-dependent and might thus link methylation with neurodegeneration. Low SAM and increased S-adenosylhomocysteine (SAH) can enhance the risk of dementia. Methods:  We studied the effect of hyperhomocysteinemia on P-tau(ser396), pNF-H (heavy chain), and PP2A-activity and level ...

N-3 polyunsaturated fatty acids (n-3 PUFAs) are essential for brain development and function, but the appropriate quantity of dietary n-3 PUFAs and ratio of n-6/n-3 PUFAs have not been clearly determined. In this study, we investigated the effects of different dietary ratios of n-6/n-3 PUFAs on the brain structural development ...

The cerebrovascular pathology is an important contributor to the death rate presently. Hyperlipidemia , an established risk factor for cardiovascular diseases, is also incriminated in the neurodegenerative disorders. The aim of this study was to evaluate the effect of a hyperlipidemic (HL) diet on the morphology of the cerebral vessels ...

Currently, there are no reports in the literature demonstrating any animal model that ingests one of the fattiest animal food source, the bovine brain. We hypothesized that a high-fat diet (HFD), based on dried bovine brain, could be used to develop an animal model possessing a spectrum of insulin resistance-related ...

Cholesterol is essential to the functions of the brain, which contains approximately 20% of the body's stores of this sterol. Most brain cholesterol is found in compacted myelin. The operation of the blood brain barrier (BBB) precludes the uptake of cholesterol from the periphery and consequently this sterol is produced ...

We previously reported impaired cholesterol biosynthesis in rodent Huntington Disease (HD) models and HD patients' fibroblasts and post mortem brains. We also found that plasma levels of 24S-hydroxycholesterol (24OHC), the brain specific elimination product of cholesterol considered a marker of brain cholesterol turnover, were significantly reduced in HD patients at ...

A diet consisting of high levels of saturated fat has been linked to a dramatic rise in obesity, Type II diabetes and metabolic syndrome. The effect of these co-morbidities on stroke outcome has not been examined in detail in human or animal studies. In this study we hypothesized that maintaining ...

The effect of starch gelatinisation degree in extruded feed on intestinal morphology, intestinal pH and faecal bacteriology was investigated in pigeons. Extruded complete pigeon diets would offer the principle advantage of providing equilibrated nutrients and energy, but factors such as starch gelatinisation require investigation before these diets are offered as ...

Several sources of information suggest that human beings evolved on a diet that had a ratio of omega-6 to omega-3 fatty acids (FA) of about 1/1; whereas today, Western diets have a ratio of 10/1 to 20-25/1, indicating that Western diets are deficient in omega-3 FA compared with the diet ...

Serotonin (5HT) synthesis in brain is influenced by precursor (tryptophan (TRP)) concentrations, which are modified by food ingestion. Hence, in rats, a carbohydrate meal raises brain TRP and 5HT; a protein-containing meal does not, but little attention has focused on differences among dietary proteins. Recently, single meals containing different proteins ...

The studies employed the cholesterol-fed rabbit model of Alzheimer's disease (AD) to investigate the relationship between AD-like neurofibrillary tangle (NFT) neuropathology and tau protein levels as the main component of NFT. We measured brain and plasma tau levels and semiquantified NFT-like neuropathology in cholesterol-fed rabbits administered drinking water of varying ...

A healthy, balanced diet is essential for both physical and mental well-being. Such a diet must include an adequate intake of micronutrients, essential fatty acids, amino acids and antioxidants. The monoamine neurotransmitters, serotonin, dopamine and noradrenaline, are derived from dietary amino acids and are involved in the modulation of mood, ...

The domestic cat (Felis catus), a carnivore, naturally eats a very low carbohydrate diet. In contrast, the dog (Canis familiaris), a carno-omnivore, has a varied diet. This study was performed to determine the expression of the intestinal brush border membrane sodium/glucose cotransporter, SGLT1, sweet receptor, T1R2/T1R3, and disaccharidases in these ...

This study was undertaken to investigate the link between dietary fat content and intestinal levels of anorectic N-acylethanolamines (NAEs), including oleoylethanolamide (OEA), palmitoylethanolamide (PEA), and linoleoylethanolamide (LEA). Male rats were fed high-fat diets (HFDs) with variable percentages of fat [20-45% of total energy (E%)] for 1-7 d; afterward, the jejunums ...

The aims of this study were to investigate the mechanism of atrophic change in ileal mucosa supplied with an elemental diet (ED) and to assess the value of supplemented fat emulsion in the prevention of atrophic change. In experiment 1, 25 male Wistar rats with a body weight of 160-180 ...

Right from birth, the lymphatics play a crucial role in dietary functions. A majority of the lipid absorbed from the newborn's lipid-rich diet enters the blood circulation through the lymphatic system, which transports triglyceride-loaded particles known as chylomicrons from the villi of the small intestine to the venous circulation near ...

After loss of intestinal surface area, the remaining bowel undergoes a morphometric and functional adaptive response. Enterocytic expression of the transcriptional coregulator tetradecanoyl phorbol acetate induced sequence 7 (Tis7) is markedly increased in a murine model of intestinal adaptation. Mice overexpressing Tis7 in intestine have greater triglyceride absorption and weight ...

To investigate the effects of a dietary antibiotic growth promoter (florfenicol) and a Saccharomyces cerevisiae fermentation product (DVAQUA) on growth, G:F, daily feed intake, intestinal bacterial community, and nonspecific immunity of hybrid tilapia (Oreochromis niloticus ♀ × Oreochromis aureus ♂), a 16-wk feeding trial was conducted in a recirculating aquaculture ...

The 16S rDNA PCR-DGGE and rpoB quantitative PCR (RQ-PCR) techniques were used to evaluate the effects of dietary flavomycin and florfenicol on the autochthonous intestinal microbiota of hybrid tilapia. The fish were fed four diets: control, dietary flavomycin, florfenicol and their combination. After 8 weeks of feeding, 6 fish from each ...

The study investigated the effects of dietary supplementation with spray-dried animal plasma (SDAP) on growth performance, intestinal morphology, as well as serum and intestinal cytokines and antioxidant indicators of artificially reared neonatal piglets. Three diets, 1) control (a fish meal basal diet), 2) SDAP (containing 10% SDAP), and 3) autoclaved ...

Long chain polyunsaturated fatty acids (LCPUFA)seem to be the most trophic macronutrients in inducing intestinal adaptation in adult short bowel syndrome (SBS), although their effects on intestinal adaptation in infants with SBS remain unknown.It is hypothesized that a high fat diet enriched with n-3 LCPUFA derived from fish oil (FO) ...

AIM: To assess Pediococcus acidilactici as a dietary supplement for on-growing red tilapia (Oreochromis niloticus). METHODS AND RESULTS: Tilapia were fed either a control diet or control diet supplemented with Ped. acidilactici at 10(7) CFU g(-1) for 32 days. Ped. acidilactici colonized the intestinal tract and significantly affected the intestinal ...

Hyperproteic diets are used in human nutrition to obtain body weight reduction. Although increased protein ingestion results in an increased transfer of proteins from the small to the large intestine, there is little information on the consequences of the use of such diets on the composition of large intestine content ...

Several steps of the HDL-mediated reverse cholesterol transport (RCT) are transcriptionally regulated by the nuclear receptors LXRs in the macrophages, liver, and intestine. Systemic LXR activation via synthetic ligands induces RCT but also causes increased hepatic fatty acid synthesis and steatosis, limiting the potential therapeutic use of LXR agonists. During ...

Pleuronectiforms are an important group of fish, and one of their species, Solea senegalensis (Kaup 1858), has been extensively studied at different levels, although information about its intestinal microbiota and the effects of different factors on it is very scarce. Modern aquaculture industry demands strategies which help to maintain a ...

Cholesterol metabolism is tightly regulated with the majority of de novo cholesterol synthesis occurring in the liver and intestine. 3 Hydroxy-3-methylglutaryl coenzyme A reductase, a major enzyme involved in cholesterol synthesis, is raised in both liver and intestine in diabetic animals. Niemann PickC1-like1 protein regulates cholesterol absorption in the intestine ...

The diverse nature of intestinal alkaline phosphatase (IAP) functions has remained elusive, and it is only recently that four additional major functions of IAP have been revealed. The present review analyzes the earlier literature on the dietary factors modulating IAP activity in light of these new findings. IAP regulates lipid ...

In vitro supplementation of the bile salt, taurodeoxycholic acid (TDCA), has been shown to stimulate proliferation and prevent intestinal apoptosis in IEC-6 cells. We hypothesize that addition of TDCA to a rodent liquid diet will be protective against induced intestinal injury. C57Bl6 mice were fed a liquid diet with or ...

The metabolic syndrome (MetS) and conditions of insulin resistance are often characterized by an increase in cardiovascular disease (CVD) risk without a concomitant increase in low-density lipoprotein cholesterol (LDL-C), suggesting that other atherogenic pathways maybe involved. Intestinally derived chylomicron remnants (CM-r) are also thought to contribute to atherogenic dyslipidemia during ...

The health benefits of breast-feeding have been recognised for a long time. In particular, breast-feeding is associated with lower incidence of necrotising enterocolitis and diarrhoea during the early period of life and with lower incidence of inflammatory bowel diseases, type 2 diabetes and obesity later in life. The higher nutritional ...

A number of different food components are known to reduce plasma and LDL-cholesterol levels by affecting intestinal cholesterol absorption. They include: soluble fibers, phytosterols, saponins, phospholipids, soy protein and stearic acid. These compounds inhibit cholesterol absorption by affecting cholesterol solubilization in the intestinal lumen, interfering with diffusion of luminal cholesterol ...

Alkaline phosphatase (ALP) hydrolyzes a variety of monophosphate esters and plays an important role in phosphorus (P) metabolism. Several nutrients in food have been reported to affect intestinal ALP activity in animal models. Previous reports indicated that high levels of P or phosphate in diets decreased intestinal ALP activity in ...

Size and hydrolytic activity of the gastrointestinal tracts of altricial birds undergo large and rapid changes during ontogeny. However, nothing is known about the development of the capacity of absorption of products of digestion, a factor that can limit total digestive performance. Using pharmacokinetic methods applied to wild-collected and laboratory-raised ...

The commensal microbiota plays an important role in the well-being of the host organism, and it would be worthwhile to know the tenacious communities among them. Therefore, a study was undertaken to examine the changes in constitution of the intestinal microbiota of wild fish consequential to captivity. At first, the ...

BACKGROUND: The gut plays a significant role in the development of obesity, notably through peptide signaling to the brain. However, few studies have investigated intestinal function per se in a rodent model of diet-induced obesity (DIO). Our aim was to investigate intestinal secretomotor function and glucose transport in DIO and ...

Na+/glucose co-transporter 1 (SGLT1) transports dietary sugars from the lumen of the intestine into enterocytes. Regulation of this protein is essential for the provision of glucose to the body and, thus, is important for maintenance of glucose homeostasis. We have assessed expression of SGLT1 at mRNA, protein and functional levels ...

AIM: Ezetimibe is known to target Niemann-Pick Type C1 Like1 (NPC1L1), a key protein in intestinal cholesterol absorption, and thus to decrease serum LDL-cholesterol (LDL-C) levels. The response of serum LDL-C levels to ezetimibe was reported to differe among NPC1L1 haplotypes.We analyzed NPC1L1 genotypes in Japanese and investigated differences in ...

Two trials were conducted to study the effects of dose and formulation of carvacrol and thymol on bacterial counts, metabolites and functional traits of the gut in weaned piglets. In the first experiment (Exp. I), 25 piglets (28 d, 6.59 +/- 0.48 kg BW) were allocated to five dietary treatments: ...

Ghrelin is the natural endogenous ligand for growth hormone secretagogue receptors. This peptide regulates energy homeostasis and expenditure and is a potential link between gut absorptive function and growth. We hypothesized that ghrelin may induce a proliferative and antiapoptotic action promoting the recovery of the hypotrophic gut mucosa. Therefore, the ...

Clinically relevant fat malabsorption is usually due to impaired intestinal fat digestion (lipolysis) and/or to impaired solubilization of the lipolytic metabolites. We hypothesized that Gelucire 44/14 - a semi-solid self-micro-emulsifying excipient - could increase fat absorption. In relevant rat models for impaired lipolysis or for impaired solubilization we tested whether ...

BACKGROUND & AIMS: Starvation induces massive perturbations in metabolic pathways involved in energy metabolism, but its effect on the metabolism of lipids, particularly cholesterol, is little understood. METHODS: A comparative genomic analysis of the gut and the liver in response to fasting was performed, with intestinal perfusion and lipid profiling ...

As a natural antioxidant derived from dietary sources, lycopene has attracted considerable attention as a potent chemopreventative agent. Lycopene is an extremely lipophilic compound and absorption from dietary sources is estimated to be low and highly variable. As a result, plasma lycopene concentrations are poorly correlated with dietary intake of ...

OBJECTIVES: Intestinal permeability and barrier function are regulated by expression of tight junction proteins. Lipopolysaccharide (LPS), tumor necrosis factor-alpha, and interleukin-1beta induce expression of nitric oxide (NO) and reduce the expression of gut tight junction proteins. The purpose of this study was to determine whether dietary gangliosides (GGs) increase the ...

Intestinal bacteria are thought to be involved in the initiation and perpetuation of inflammatory bowel diseases. Prebiotics (non-digestable dietary carbohydrate) have beneficial properties that alter the intestinal flora and contain glutamine-rich protein. Glutamine significantly decreases indices of inflammation. In this study, an enzymatic hydrolysate of corn gluten (EHCG) was administered ...

Anticancer chemotherapy often induces side effects such as mucositis. Recent data suggest that a diet, Clinutren Protect (CP), containing whey proteins, glutamine, and transforming growth factor-beta (TGFbeta)-rich casein limits intestinal mucositis and improves recovery after a single methotrexate (MTX) challenge in rats. Chemotherapy consists of alternating periods of treatment and ...
