The Thriposha programme is a community-level nutrition intervention in Sri Lanka that provides a combination of energy, protein and micronutrients as a 'ready-to-eat' cereal-based food. We measured the bioavailability of Fe and Zn from Thriposha formula at two different molar ratios of Zn:Fe in order to determine the effect on Fe and Zn absorption. Children 4-7 years (n 53) were given a meal pr...

1. Micropuncture studies of chloride and bicarbonate absorption in the proximal tubule under free flow conditions were performed during exposure to 12% COz in air, during recovery from COz on a low chloride diet with and without concomitant sodium restriction, and during re-exposure to 12% COz in air with continuing chloride restriction. 2. After 3 hr of exposure to COz there was a significant ...

While mapping algal blooms from space is now well-established, mapping undesirable algal blooms in eutrophicated coastal waters raises further challenge in detecting individual phytoplankton species. In this paper, an algorithm is developed and tested for detecting Phaeocystis globosa blooms in the Southern North Sea. For this purpose, we first measured the light absorption properties of two ph...

The roles of polymorphisms of the sitosterolemia genes ABCG5 and ABCG8 in the regulation of cholesterol metabolism and insulin sensitivity were studied in mildly hypercholesterolemic noncoronary subjects (n = 263, 144 men and 119 women) divided into tertiles by baseline serum cholestanol-to-cholesterol ratio (< or = 118.3 and > or = 147.7 10(2) x mmol/mol cholesterol), a surrogate marker of cho...

The monochromatic absorption coefficient of silicon, inducing the depth penetration light into base solar cell, is used through back surface recombination velocity expressions, to determine optimum thickness necessary for production a large photocurrent. absorption-generation-diffusion and (bulk surface) phenomena are taken account in determining an n+ -p-p+ bifacial it manufacture process opti...

BACKGROUND Erythorbic acid, a stereoisomer of ascorbic acid with similar physicochemical properties, is widely used as an antioxidant in processed foods. OBJECTIVES The aims of the present study were to evaluate the effect of erythorbic acid on iron absorption from ferrous sulfate at molar ratios of 2:1 and 4:1 (relative to iron) and to compare the effect of erythorbic acid directly with that...

BACKGROUND Few data exist on the ability of postmenopausal women to absorb calcium from diets habitually low in calcium. OBJECTIVE The objective of this study was to evaluate fractional calcium absorption from a green leafy vegetable vs. milk in relation to vitamin D status. METHODS We measured fractional calcium absorption from both a dairy- and plant-based source in 19 postmenopausal Thai...

OBJECTIVE Women with gestational diabetes mellitus (GDM) show reduced insulin sensitivity and markedly elevated glucose excursions. After delivery, GDM mostly reverts to normal glucose tolerance (NGT), although leaving an increased risk of type 2 diabetes. Because gastrointestinal function changes during pregnancy causing vomiting, constipation, or reduced motility, we thought that gut glucose ...

Mammalian type II sodium-phosphate cotransporter (NaPi-II) and inorganic phosphate uptake stimulator (PiUS) genes are upregulated by dietary phosphorus (P) restriction to increase intestinal and renal P transport, but little is known about NaPi-II and PiUS regulation in other vertebrates. We studied the 1). the tissue distribution and dietary regulation of NaPi-II, PiUS, and sodium-glucose cotr...

The development of oral rehydration solutions (ORSs) has been one of the important therapeutic advances of this century. The optimal formulation, however, of ORSs for both cholera and other infective diarrhoeas is still debated. Part of the problem in developing ORSs has been the lack of adequate test systems for the assessment of new formulations before clinical trial. We have developed a jeju...
