Filter by:The purpose of this prospective, observational study is to evaluate the tolerability and acceptability of Zero minis, a range of protein substitute tablets for use in the dietary management of children with either TYROSINAEMIA Type I, II, III or ALKAPTONURIA, HOMOCYSTINURIA, or MAPLE SYRUP URINE DISEASE (MSUD) over the age of 7 years.
Several natural compounds have been explored as immune-boosting, antioxidant, and anti-inflammatory dietary supplements. Amongst them, hydroxytyrosol a natural antioxidant found in olive products, and endemic medicinal plants have attracted the scientific's community and industry's interest. The safety and biological activity of a standardised supplement containing 10 mg of hydroxytyrosol synthesized using genetically modified Escherichia coli strains and equal amounts (8.33 μL) of essential oils from oregano vulgaris, sage officinalis and crithmum maritimum in an open-label, single-arm, prospective clinical study were studied. The supplement capsules were given to 12 healthy subjects, aged 26-52, once a day for 8 weeks.
Raised plasma Homocysteine (Hcy) was 1st proposed as a cause of vascular pathology in patients with inherited disorders of Homocysteine metabolism.leading to the hypothesis that individuals with slight to moderate elevated levels of Homocysteine may have an increased hazard for vascular disease. As an amino acid with a reactive sulfhydryl group, homocysteine has been proposed to intermediate vascular inflammation and damage by stimulating oxidative stress secondary to reactive oxygen species accumulation. which in turn leads to an rise in cardiac and vascular disease risk by stimulating endothelial dysfunction, smooth muscle cell proliferation, and vascular calcification. Consistent with this hypothesis, hyperhomocysteinemia a has been associated with an increased risk for coronary heart disease (CHD), heart failure, atrial fibrillation, stroke, and mortality.
Changes in homocysteine values after bariatric surgery remain controversially discussed. This is the first comprehensive summary to depict timeline changes in homocysteine levels following laparoscopic roux-en-Y gastric bypass.
In a cross-over study the investigators evaluate the effects of natural (Panmol-B-Complex) (Pan [Greek] = all; moles [Latin] = molecules/particles - brand name) versus synthetic vitamin B complexes to identify the bioavailability of distinct vitamins as well as long-term effects. The primary hypothesis for this study: "Natural Vitamin B-complexes are as effective as synthetic Vitamin B-complexes or better." For this reason 30 subjects (18 to 65y; BMI >19 to <29) were recruited for this study. The study population was divided into 2 groups of each 15 subjects in a cross-over trial. Vitamin supplementation consisted of Thiamine (2.93 mg), Riboflavin (3.98 mg), Niacin (29.85 mg), Pantothenic acid (10.95 mg), Pyridoxine (3.38 mg), Biotin (0.108 mg), Folic acid (0.69 mg) and Cobalamin (8.85 µg) per day in both groups. Blood samples are taken at baseline - 1.5h after vitamin supplementation - 4h - 7h - 6 weeks - wash out phase I (2 weeks); start cross-over: baseline - 1.5h after vitamin supplementation - 4h - 7h - 6 weeks - washout phase II (6 weeks). In case of main target criteria Thiamin, Riboflavin, Pyridoxine, Folic acid and Cobalamin were measured in serum as well as total peroxides (µmol/L), peroxidase-activity (U/L), total antioxidant status (mmol/L) and polyphenols (mmol/L).
