Tiange Li, Xue Cheng, Min Du, Bin Chen, Xueying Mao
Recently, we have shown that casein glycomacropeptide hydrolysates (GHP) exhibit both anti-inflammatory and anti-oxidative activities in vitro. However, whether heme oxygenase-1 (HO-1) is involved in the cytoprotective effect of GHP against the inflammatory status remains unclear. Therefore, we hypothesized that HO-1 is a potential target of GHP, which mediates its anti-inflammatory effect. Here, GHP inhibited the intracellular reactive oxygen species (ROS) accumulation and NADPH oxidase 2 (NOX2) expression and enhanced reduced glutathione (GSH) levels in LPS-stimulated RAW264...

The effect of several types of whey milk - cow, sheep, goat and a mixture of them (60 : 20 : 20, respectively) - was assessed in the human gut microbiota. The prebiotic potential of these substrates was evaluated through in vitro gastrointestinal digestion following faecal batch culture fermentations (mimicking colonic fermentation) for 48 hours, using faeces from normal-weight (NW) and obese (OB) donors. Throughout the fermentation process, pH, gas production, short chain and branched fatty acids (SCFA-BCFA) were measured, as well as the changes of microbiota using qPCR...

It has been demonstrated that mangiferin can ameliorate hypertriglyceridemia by modulating the expression levels of genes involved in lipid metabolism in animal experiments, but its effects on the serum metabolic fingerprinting of hyperlipidemia animal models have not been reported. Thus, a NMR-based metabolomics approach was conducted to explore the effects of mangiferin on hyperlipidemia hamsters and to gain a better understanding of the involved metabolic pathways. Hamsters fed with a high-fat diet were orally administered with mangiferin 150 mg per kg BW once a day for 8 weeks...

Amelia Torcello-Gómez, Timothy J Foster
The development of emulsion-based products through optimisation of ingredients, reduction in energy-input during manufacture, while fulfilling healthy attributes, are major objectives within the food industry. Instant emulsions can meet these features, but comprehensive studies are necessary to investigate the effect of the initial formulation on the final microstructure and, in turn, on the in vitro lipolysis, comprising the double aim of this work. The instant emulsion is formed within 1.5-3 min after pouring the aqueous phase into the oil phase which contains a mixture of emulsifier (Tween 20), swelling particles (Sephadex) and thickeners (hydroxypropylmethylcellulose, HPMC, and guar gum, GG) under mild shearing (180 rpm)...

Hypertension is associated with enhanced vascular oxidative stress and impaired endothelial function, which is related to an imbalance between reactive oxygen species and nitric oxide bioavailability. Short-term supplementation with a polyphenol-rich powdered red wine pomace seasoning (RWPS) was investigated for its effects on blood pressure and biomarkers of endothelial dysfunction and oxidative status in a model of essential hypertension. Male spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto rats (12-week-old, 5 rats per group) were administered RWPS (300 mg kg(-1) day(-1); equivalent to 7...

The aim of the present research was to study the protective effects and underlying mechanisms of apigenin on d-galactose-induced aging mice. Firstly, apigenin exhibited a potent antioxidant activity in vitro. Secondly, d-galactose was administered by subcutaneous injection once daily for 8 weeks to establish an aging mouse model to investigate the protective effect of apigenin. We found that apigenin supplementation significantly ameliorated aging-related changes such as behavioral impairment, decreased organic index, histopathological injury, increased senescence-associated β-galactosidase (SAβ-gal) activity and advanced glycation end product (AGE) level...

Echinacoside is a phenylethanoid glycoside and possesses neuroprotective activity in vitro and in vivo. This study investigates the role of the amyloid cascade and central neuronal function on the protective effects of echinacoside in amyloid β peptide 1-42 (Aβ 1-42)-treated SH-SY5Y cells and an Aβ 1-42-infused rat. Echinacoside inhibited Aβ 1-42 oligomerization in vitro and restored the cell viability that was reduced by Aβ 1-42 in SH-SY5Y cells. Intracisternal infusion with Aβ 1-42 by an osmotic pump caused cognitive deficits, an increase in amyloid deposition and acetylcholinesterase activities, and a decrease in the brain's levels of acetylcholine and dopamine...

Phenolic compounds are present in human fluids (plasma and urine) mainly as glucuronidated and sulfated metabolites. Up to now, due to the unavailability of standards, enzymatic hydrolysis has been the method of choice in analytical chemistry to quantify these phase II phenolic metabolites. Enzymatic hydrolysis procedures vary in enzyme concentration, pH and temperature; however, there is a lack of knowledge about the stability of polyphenols in their free form during the process. In this study, we evaluated the stability of 7 phenolic acids, 2 flavonoids and 3 prenylflavanoids in urine during enzymatic hydrolysis to assess the suitability of this analytical procedure, using three different concentrations of β-glucuronidase/sulfatase enzymes from Helix pomatia...

Cardiovascular diseases (CVDs) are one of the major causes of mortality and disability in Western countries. Prevention is known to be the cornerstone to lessen the incidence of CVDs and also to reduce the economic burden of both the citizen and the healthcare system. "Interventional medicine" certainly puts lifestyle modification as the first therapeutic step, including a healthy diet and physical activity. Secondly, a large body of research individuated a number of food and plant bioactives, which are potentially efficacious in preventing and reducing some highly prevalent CV risk factors, such as hypercholesterolemia, hypertension, vascular inflammation and vascular compliance...
