Citrus tamurana Hort. ex Tanaka (Hyuganatsu orange)-derived arabinogalactan suppresses bone turnover in postmenopausal women: A randomized placebo-controlled study.

Aim: To evaluate Hyuganatsu oranges (Citrus tamurana Hort. Ex Tanaka) derived arabinogalactan for bone turnover, we performed a randomized placebo-controlled trial.

Methods: Sixty-three postmenopausal women were age-stratified and randomly assigned to receive arabinogalactan-rich hyuganatsu juice (study group) or a placebo drink (control group) for 90 days.

Taurine Improves Lipid Metabolism and Increases Resistance to Oxidative Stress.

Calorie restriction (CR) by 30-40% decreases morbidity of age-related diseases and prolongs the lifespan of various laboratory animal species. Taurine (2-aminoethanesulfonic acid) is an important nutrient for lipid metabolism as it conjugates bile acids. Here, we investigated how taurine supplementation induces effects similar to the CR beneficial effects.

Taurine ameliorates cholesterol metabolism by stimulating bile acid production in high-cholesterol-fed rats.

This study was designed to investigate the effects of dietary taurine on cholesterol metabolism in high-cholesterol-fed rats. Male Sprague-Dawley rats were randomly divided into two dietary groups (n = 6 in each group): a high-cholesterol diet containing 0.5% cholesterol and 0.

Effect of Vaccinium ashei reade leaf extracts on lipid metabolism in obese OLETF rats.

The effects of a hot water extract and fractional extracts from rabbiteye blueberry (Vaccinium ashei reade) leaves (BBL) on lipid metabolism were studied in obese Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Feeding the hot water extract and fractional extracts from BBL alleviated hepatic triglyceride accumulation in the rats. Additionally, feeding with the flavonol glycoside (FG) and proanthocyanidin (PA) fractions lowered serum cholesterol levels in the obese rats.

Hypotriacylglycerolemic and antiobesity properties of a new fermented tea product obtained by tea-rolling processing of third-crop green tea (Camellia sinensis) leaves and loquat (Eriobotrya japonica) leaves.

We manufactured a new fermented tea by tea-rolling processing of third-crop green tea (Camellia sinensis) leaves and loquat (Eriobotrya japonica) leaves. The mixed fermented tea extract inhibited pancreatic lipase activity in vitro, and effectively suppressed postprandial hypertriacylglycerolemia in rats. Rats fed a diet containing 1% freeze-dried fermented tea extract for 4 weeks had a significantly lower liver triacylglycerol concentration and white adipose tissue weight than those fed the control diet lacking fermented tea extract.

Hypoglycemic activity of Eriobotrya japonica seeds in type 2 diabetic rats and mice.

The hypoglycemic effects of Eriobotrya japonica seeds were investigated in type 2 diabetic Otsuka Long-Evans Tokushima fatty (OLETF) rats and KK-A(y) mice. The rats and mice were fed on a diet containing 10% powdered Eriobotrya japonica seeds with the coat intact for 4 months. Although the blood glucose concentration in the OLETF rats fed on the control diet without Eriobotrya japonica seeds was increased with time, the concentration in the OLETF rats fed on the diet with Eriobotrya japonica seeds was consistently low throughout the experimental period and was comparable to the level in Long-Evans Tokushima Otsuka (LETO) rats which are normal non-diabetic rats.

Genetically modified rapeseed oil containing cis-9,trans-11,cis-13-octadecatrienoic acid affects body fat mass and lipid metabolism in mice.

Punicic acid, one of the conjugated linolenic acid (CLN) isomers, exerts a body-fat reducing effect. Although punicic acid is found in pomegranate and Tricosanthes kirilowii seeds, the amount of this fatty acid is very low in nature. The goal of this study was to produce a transgenic oil containing punicic acid.

Lymphatic absorption and deposition of various plant sterols in stroke-prone spontaneously hypertensive rats, a strain having a mutation in ATP binding cassette transporter G5.

ATP binding cassette transporter G5 (ABCG5) and ATP binding cassette transporter G8 (ABCG8) have been suggested to transport absorbed plant sterols and cholesterol from enterocytes to the intestinal lumen and from hepatocytes to bile. It has been thought that mutations of ABCG5 or ABCG8 cause the deposition of plant sterols in the body. In the present study, lymphatic absorption of various plant sterols and their deposition in various tissues was investigated in stroke-prone spontaneously hypertensive rats (SHRSP), having a mutation in Abcg5 and depositing plant sterols in the body.

Effects of dietary oyster extract on lipid metabolism, blood pressure, and blood glucose in SD rats, hypertensive rats, and diabetic rats.

Oyster extract was prepared by hydrolysis of oyster protein with proteases, Aloase (a protease from Bacillus subtilis), and Pancitase (a protease from Aspergillus oryzae). Rats were fed a diet containing 20% casein (the control diet) or 15% casein and 5% oyster extract (the oyster extract diet) as the protein source. The oyster extract diet exerted a significant reduction in serum cholesterol and liver triglyceride concentrations as compared with the control diet in Sprague-Dawley (SD) rats fed cholesterol-supplemented diets for 4 weeks.

Lanosterol synthase mutations cause cholesterol deficiency-associated cataracts in the Shumiya cataract rat.

The Shumiya cataract rat (SCR) is a hereditary cataractous strain. It is thought that the continuous occurrence of poorly differentiated epithelial cells at the bow area of the lens forms the pathophysiological basis for cataract formation in SCRs. In this study, we attempted to identify the genes associated with cataract formation in SCRs by positional cloning.

Effects of feeding oyster, Crassostrea gigas, on serum and liver lipid levels in rats.

The effects of feeding dietary and defatted oyster meat on lipid metabolism were investigated in rats by comparing measurements with those of casein and soybean protein. In the first experiment, male rats were fed 0.1% and 1% cholesterol-supplemented diets containing casein, oyster or soybean protein under the same dietary level of protein (20%).
