Accumulating evidence suggests a relationship between the gut microbiota and development of obesity, indicating potential probiotics as therapeutic approach. Bifidobacterium breve B-3 has been shown to exert anti-obesity effects in high-fat diet-induced obese mice. In present study, consumption B. by healthy pre-obese (25 ≤ BMI < 30) adults were investigated randomized, double-blind, placebo-controlled trial (trial registration: UMIN-CTR No. 000023919; preregistered on September 2, 2016)....

Indole in the gut is formed from dietary tryptophan by a bacterial tryptophan-indole lyase. not only triggers biofilm formation and antibiotic resistance microbes but also contributes to progression of kidney dysfunction after absorption intestine sulfation liver. As an essential amino acid for humans, these events seem inevitable. Despite this, we show proof-of-concept study that exogenous indole can be converted immunomodulatory metabolite, indole-3-lactic (ILA), previously unknown...

Human noroviruses cause significant morbidity and mortality worldwide, but lack approved antivirals or vaccines to treat prevent infections. The recent development of two cell culture systems in human transformed B cells (BJABs) non-transformed intestinal enteroid cultures overcomes a main limitation identifying molecules with anti-norovirus activities. Lactoferrin is an iron-binding glycoprotein found the milk most mammals, broad spectrum antimicrobial activities, including against related...

Summary Background Aloe vera is a traditional medical plant whose gel has been widely used in skin care. Previously, we have identified sterols from as active ingredients. This study investigated the protective effects of without polysaccharides, against ultraviolet B ( UVB )‐induced photoaging mice using extract AVGE ) obtained by supercritical fluid extraction. Methods was supplemented diet (12 or 120 ppm), and HR ‐1 hairless were exposed to irradiation for 7 weeks. Skin measurements...

Abstract Understanding the viability of ingested probiotics within gastrointestinal tract is essential for evaluating their efficacy and deciphering mechanisms action. Detecting Bifidobacterium longum subspecies BB536 particularly challenging owing to its indistinguishability from naturally abundant B. species in human gut. We aimed address this challenge by developing a selective culture medium employing propidium monoazide-quantitative polymerase chain reaction (PMA-qPCR) method verify...

The aim of the present study was to investigate anti-obesity effects Aloe vera gel administration in male Sprague-Dawley (SD) rats with diet-induced obesity (DIO). SD at 7 wk age were fed either a standard diet (10 kcal% fat) (StdD) or high-fat (60 (HFD) during experimental period. Four weeks after HFD-feeding, DIO (11 age) orally administered two doses powder (20 and 200 mg/kg/d) for 90 d. Body weights (g) body fat (%) HFD significantly higher than those StdD-fed rats. Although modest...

Titanium (Ti) is an osteoconductive material that routinely used as a bulk implant to fix and restore bones teeth. This study explored the effective use of Ti bone engineering scaffold. Challenges overcome were: (1) difficult liquid/cell infiltration into microfiber scaffolds due hydrophobic nature Ti; (2) cell attachment on thin curved microfibers. A recent discovery UV-photofunctionalization prompted us examine its effect scaffolds. Scaffolds in disk form were made by weaving grade 4 pure...

Poly(methyl methacrylate) (PMMA)-based bone cement, which is widely used to affix orthopedic metallic implants, considered bio-tolerant but lacks osteoconductivity and cytotoxic. Implant loosening toxic complications are significant recognized problems. Here we devised two strategies improve PMMA-based cement: (1) adding 4-methacryloyloxylethyl trimellitate anhydride (4-META) MMA monomer render it hydrophilic; (2) using tri-n-butyl borane (TBB) as a polymerization initiator instead of...
