Effectiveness of genetic feedback on alcohol metabolism to reduce alcohol consumption in young adults: an open-label randomized controlled trial.

Background: It is unclear whether brief interventions using the combined classification of alcohol-metabolizing enzymes aldehyde dehydrogenase 2 (ALDH2) and alcohol dehydrogenase 1B (ADH1B) together with behavioral changes in alcohol use can reduce excessive alcohol consumption. This study aimed to examine the effects of a brief intervention based on the screening of ALDH2 and ADH1B gene polymorphisms on alcohol consumption in Japanese young adults.

Methods: In this open-label randomized controlled trial, we enrolled adults aged 20-30 years who had excessive drinking behavior (average amount of alcohol consumed: men, ≥  4 drinks/per day and women, ≥  2 drinks/per day; 1 drink = 10 g of pure alcohol equivalent).

Supplementation with Fermented Barley Extract Prevents Mammary Epithelial Cell Invasion in an Early Breast Cancer Model.

Diet-based prevention of malignant transformation contributes to the maintenance of quality of life by avoiding a battle against cancer. Invasion is one of the features of malignant breast cancer, and the prevention of invasion may reduce breast cancer malignancy. A recently established early breast cancer model system showed mammary ductal dysplasia with invasion in mice.

Effects of a pyroglutamyl pentapeptide isolated from fermented barley extract on atopic dermatitis-like skin lesions in hairless mouse.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by pruritic and eczematous skin lesions. The skin of AD patients is generally in a dried condition. Therefore, it is important for AD patients to manage skin moisturization.

GABA promotes elastin synthesis and elastin fiber formation in normal human dermal fibroblasts (HDFs).

The multiple physiological effects of γ-aminobutyric acid (GABA) as a functional food component have been recently reported. We previously reported that GABA upregulated the expression of type I collagen in human dermal fibroblasts (HDFs), and that oral administration of GABA significantly increased skin elasticity. However, details of the regulatory mechanism still remain unknown.

Effects of GABA on the expression of type I collagen gene in normal human dermal fibroblasts.

We examined the effects of GABA on type I collagen gene expression in normal human dermal fibroblasts. Real-time PCR analysis indicated GABA increased the level of type I collagen transcripts, and suppressed the expression of matrix metalloproteinase-1, which is a collagen-degrading enzyme. These results suggest GABA improves the skin elasticity by regulating type I collagen expression.

Fermented barley extract supplementation ameliorates metabolic state in stroke-prone spontaneously hypertensive rats.

We studied the effects of fermented barley extract P (FBEP) in stroke-prone spontaneously hypertensive rats (SHRSP). Male 10-week-old SHRSP were divided into three groups that were fed: an AIN-93M diet (control), a low dose of FBEP (4 g/kg; FBEP1), and a high dose of FBEP (20 g/kg; FBEP2) for three weeks. Hypertension was significantly improved by the use of FBEP supplementation.

Fermented barley extract supplementation maintained antioxidative defense suppressing lipopolysaccharide-induced inflammatory liver injury in rats.

Utilizing phytochemicals in treating inflammation is becoming a viable alternative to pharmacological treatment. We have reported that fermented barley extract (FBE) effectively suppresses oxidative stress in chronically ethanol-fed rats. Here we report that FBE suppressed acute increases in oxidative stress as a response to lipopolysaccharide (LPS)-induced inflammation.

Effects of a fermented barley extract on subjects with slightly high serum uric acid or mild hyperuricemia.

The uric acid-lowering effect and safety of a fermented barley extract P (FBEP) prepared from barley-shochu distillery by-products were investigated in a randomized, placebo-controlled, parallel-group, double-blinded study. A total of 111 subjects with serum uric acid levels of 6.0-7.

Effects of single and combined administration of fermented barley extract and gamma-aminobutyric acid on the development of atopic dermatitis in NC/Nga mice.

We examined the effects single and combined administration of fermented barley extract P (FBEP), prepared from barley-shochu distillery by-products, and gamma-aminobutyric acid (GABA) on the development of atopic dermatitis (AD)-like skin lesions in NC/Nga mice. Single administration of FBEP and GABA dose-dependently reduced the development of AD-like skin lesions in mice. GABA reduced the development of AD-like skin lesions by suppressing serum immunoglobulin E (IgE) and splenocyte interleukin (IL)-4 production, while FBEP reduced skin lesions without affecting the IgE or cytokine production.
