The high prevalence of iron deficiency in infants and in women of reproductive age and more recent concerns about iron overload in genetically susceptible persons emphasize the potential importance...
To gain more insight into the relation between vegetable consumption and the risk of chronic diseases, it is important to determine the bioavailability of carotenoids from vegetables and the effect...
There is a critical need to estimate dietary folate intakes for nutrition monitoring and food safety evaluations, but available intake data are seriously limited by several factors.
Interest in carotenoids has increased over the past decade from scientists involved in a variety of disciplines. Although some human nutritionists have focused their efforts on the potential role o...
The title and conclusions of the article, “Bioavailability of iron glycine as a fortificant in infant foods,” by Fox et al (1) are not supported by the data presented. Their data show that the absorpt...
Patients with carboxylase deficiency are treated with pharmacologic doses of biotin.
Frank, symptomatic biotin deficiency probably occurs rarely. The only well-documented cases have occurred in association with total or near total intravenous feeding without biotin supplementation, ...
目的研究脱水穿心莲内酯在大鼠体内的口服生物利用度和肠道处置,为其在临床的使用和开发提供有用的信息。方法研究脱水穿心莲内酯在大鼠体内的药代动力学行为。采用Caco-2细胞模型和大鼠在体肠灌流模型研究脱水穿心莲内酯在大鼠体内的肠道处置。结果脱水穿心莲内酯的口服绝对生物利用度是11.92%。在Caco-2细胞模型中,脱水穿心莲内酯从基底膜到顶端膜方向转运的表观渗透系数(5.37×10-5 cm/s)约等...
In this study, the influence of the co-existence of TiO2nanoparticles on the speciation of arsenite [As(III)]was studied by observing its adsorption and valence changing. Moreover, the influence of Ti...
Aluminum is the most abundant metal in the earth's crust. However, it is not essential for life. Owing to its specific chemical properties, aluminum inhibits more than 200 biologically important funct...
Background: The bioavailability of natural food folates is lower than that of synthetic folic acid, but no agreement exists as to the extent of the difference.Objective: In a 4-wk dietary intervention...
Background: Metronidazole has been reported to reduce postoperative anaerobic infections following surgical procedures. Because of high cost and poor availability of intravenous metronidazole compared...
Vitamin A deficiency is a serious health problem in many developing countries. Provitamin A carotenoids in fruit and vegetables are the major source of vitamin A for a large proportion of the world’s ...
Adaptation of iron absorption in response to dietary iron bioavailability is less likely in premenopausal women, who generally have lower iron stores, than in men.
