BACKGROUND Total (heme and nonheme) iron bioavailability from the US diet has been estimated to be 18% based on a single human absorption study. New data, however, suggest that it may be time to revisit this estimate. OBJECTIVE We estimated total iron bioavailability from the US diet with the use of our recently reported algorithm that estimates nonheme iron absorption and a conservative valu...

The effects of Poissonian resetting at a constant rate $r$ on the reaction time between Brownian particle and stochastically gated target are studied. switches reactive state non-reactive one. We calculate mean which subject to hits for first time, while latter is in state. search minimum that depends transition rates. When relaxation much larger than both inverse diffusion system becomes equiv...

modifying polyester spacer fabric by β-cyclodextrin produces a new product with outstanding characteristics. citric acid is used as a crosslinking agent for improvement of durability of this material in textile fabrics. in this research different concentrations of citric acid and β-cyclodextrin were applied on a 3d fabric and some properties including weight change, weight of moisture residue, ...

Rigorous packed-bed absorber modeling and simulation are significant for post-combustion CO 2 capture processes design. Hence, a good knowledge judicious selection of model parameters essential to ensure reliable predictions. In this paper, the reactive absorption into loaded aqueous monoethanolamine solution was modeled, furthermore, effects five different (kinetic model, enhancement factor, e...

Abstract Environmental sustainability is described as one that avoids the depletion or deterioration of natural resources, while also allowing for preservation long-term environmental quality. By practicing sustainability, we may assist to guarantee requirements today’s population are satisfied without risking capacity future generations meet their own needs in future. Engineers field concrete ...

reactive oxygen species (ros)plays an important role in sperm motility. the physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

AIM To demonstrate the clinical benefit of inhibiting intestinal cholesterol absorption, we evaluated the effects of ezetimibe on surrogate markers of cholesterol absorption and synthesis, lipid and glucose metabolism, and markers of obesity and inflammation. METHODS A total of 120 patients with dyslipidemia (46 men; mean age 66.5 years), who had not achieved the low density lipoprotein chole...

We have studied femtosecond carrier dynamics in InN nanowires grown by reactive vapor transport. Transient differential absorption measurements have been employed to investigate the relaxation dynamics of photogenerated carriers near and above the optical absorption edge of InN NWs where an interplay of state filling, photoinduced absorption, and band-gap renormalization have been observed. The...
