The gastrointestinal (GIT) microbiota, which plays a crucial role in human health, is influenced by a number of factors including diet. Consumption of specific dietary ingredients, such as dietary fibers and prebiotics, is an avenue by which the microbiota can be positively modulated. These substances may also reduce serum cholesterol levels through various mechanisms. Interest has increased in methods of reducing blood cholesterol level, because dyslipidemia is recognized as a contributory risk factor for the development of cardiovascular diseases...

Garcinia mangostana L. (GM, family Guttiferae) is one of the most widely recognized tropical fruits. GM is a wealthy pool of xanthones that exhibit a wide range of bioactivities. Tovophyllin A (TA) separated from GM pericarps was tested for its efficacy to ameliorate acetaminophen (APAP)-induced liver injury. Mice were injected with a single dose of APAP with or without TA pretreatment. The protective effects of TA against APAP-induced liver damage were evident through amelioration of serum indices of hepatotoxicity and improvement of hepatic histopathologic lesions...

Foams with a continuous oil phase may be stabilized using crystalline particles. Those systems are compelling because of their potential in edible oil structuring, modifying sensorial properties and creating healthier food products. This study aimed to relate oleogel (unwhipped state) properties to oil foam (whipped state) properties using a monoglyceride-sunflower oil model system. The properties of crystal-oil mixtures were influenced by time and temperature during preparation and storage. Therefore, oleogels were prepared using different tempering protocols and their resulting microstructure was investigated with rheology, differential scanning calorimetry and X-ray diffraction...

Rooibos tea is a naturally sweet and aromatic tea that is native to the Western Cape province of South Africa. Rooibos is usually fermented to produce the traditional reddish brown colour and has been found to have numerous health benefits. These include beneficial effects on osteoblasts; however, its effects on osteoclast formation and activity are unknown. Osteoclasts are large, multinucleated cells responsible for bone resorption. Binding of RANKL to its receptor on osteoclast precursors triggers the NF-κB signalling pathway leading to the formation of osteoclasts...

The delivery of active agents from organogels is becoming an important topic owing to the possibility of releasing, in a controlled way, lipophilic agents. Controlled release from foods is a topic with increasing relevance owing to the growing industrial interest towards functional or medical foods, i.e. foods containing nutraceutical agents or drugs. Anyway, release properties are related to the rheological properties of organogels, and, therefore, a deep knowledge of their microstructure and physical characteristics is necessary to design carriers with expected release properties...

This study aimed to investigate the ameliorating effect of an ethyl acetate fraction from the fruit Actinidia arguta (EFAA) on amyloid beta (Aβ)-induced neurotoxicity and cognitive deficits in ICR mice. EFAA showed potent protective effects against Aβ-induced neurotoxicity through 2',7'-dichlorofluorescein diacetate (DCF-DA), 2',3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and lactate dehydrogenase (LDH) release into the assay medium. EFAA treatment reduced the intracellular ROS level and lactate dehydrogenase (LDH) release in the mitochondria, and increased cell viability in Aβ-induced neuroblastoma MC-IXC cells...

In this study, the immunomodulatory activity of docosahexaenoic acid (DHA) on the immunosuppressive BALB/c mice model and its molecular mechanism are elucidated. It was found that the weight indexes of the spleen and thymus were significantly increased by DHA (44.0 mg kg-1 and 88.0 mg kg-1) treatment in the prevention or cure groups. The result of macrophages showed that DHA (44.0 mg kg-1 and 88.0 mg kg-1) could promote the proliferation and phagocytosis activity of macrophages in the prevention or cure groups...

The stomach is a critical organ for food digestion but it is not well understood how it operates, either when healthy or when dysfunction occurs. Stomach function depends on the timing and amplitude of wall contractions, the fill level and the type of gastric content. Using a coupled biomechanical-Smoothed Particle Hydrodynamics (B-SPH) model, we investigate how gastric discharge is affected by the contraction behaviour of the stomach wall and the viscosity of the content. The results of the model provide new insights into how the content viscosity and the number of compression waves down the length of the stomach affect the mixing within and the discharge rate of the content exiting from the stomach to the duodenum...

Specific Lactobacillus reuteri is autochthonous Lactobacillus species in humans with potential application in food production as a probiotic. The difference in colonizing Peyer's patches (PP) might decide their health-promoting properties. We aimed to investigate the difference between PP- and lumen-specific L. reuteri on antimicrobial peptide expression in this study. L. reuteri strains were isolated from PP and the lumen of C57BL/6J mice, which were used to treat mice. PP-specific L. reuteri cells stimulate RegIIIγ mRNA expression of the crypt epithelial sample...

The prevalence of diabetes reached 415 million worldwide in 2015. Polyphenol-rich food intake can benefit the glycemic control for individuals with diabetes. Fermentation may increase the bioavailability of polyphenols, which is generally low. Aronia (Aronia melanocarpa) is a polyphenol-rich berry that is native to North America. Proanthocyanins and anthocyanins are the major phenolic compounds in aronia. In this study, aronia kefir was made by fermenting cow's milk with added aronia juice. The changes in bioaccessible polyphenols of aronia kefir during digestion were assessed using an in vitro model...

Overexpression of the prosurvival protein BCL-2 contributes to malignant cell initiation, progression and resistance to treatment. Agents that function as its natural antagonists targeting BCL-2 must provide therapeutic benefit. In SW1990 pancreatic cancer cells, amplified BCL-2 was observed, which was believed to offer advantages for malignant cell survival and lead to poor patient outcome. Using structure-based virtual ligand screening, luteolin was found to be a natural small-molecule inhibitor of BCL-2, which exhibited dose-response proapoptosis activity in a BCL-2 dependent manner in vitro...

FGF21 has emerged as a key metabolism and energy homeostasis regulator. Dietary supplementation with eicosapentaenoic acid (EPA) and/or α-lipoic acid (LIP) has shown beneficial effects on obesity. In this study, we evaluated EPA and/or LIP effects on plasma FGF21 and the fatty acid (FA) profile in overweight/obese women following hypocaloric diets. At the baseline, FGF21 levels were negatively related to the AST/ALT ratio and HMW adiponectin. The weight loss did not cause any significant changes in FGF21 levels, but after the intervention FGF21 increased in EPA-supplemented groups compared to non-EPA-supplemented groups...
