The analysis of the distribution of pharmaceutical materials in tablet formulations, such as drugs and matrix elements, is critical to product performance and is used in such areas as quality control, impurity testing, and process monitoring. Recently imaging techniques, such as Raman, near-IR, and fluorescence imaging, have become popular for “visualization” of pharmaceutical formulations, all...

A suspension of nanoparticles of BSA-stabilized red amorphous elemental selenium (Se) or an aqueous solution of sodium selenite was repeatedly administered by oral gavage for 28 days at 0.05 mg kg(-1) bw per day (low dose) or at 0.5 mg kg(-1) bw per day (high dose) as Se to female rats. Prior to administration, the size distribution of the Se nanoparticles was characterized by dynamic light sca...

The sulfur-binding protein of Thiobacillus ferrooxidans ATCC 23270 was investigated. The protein composition of the bacterium's cell surface changed according to the culture substrate. Sulfur-grown cells showed greater adhesion to sulfur than iron-grown cells. The sulfur-grown cells synthesized a 40-kDa surface protein which was not synthesized by iron-grown cells. The 40-kDa protein had thiol ...

Three month old Thunbergia alata were exposed for 13 days to 10 μM selenite to determine the biotransformation of selenite in their roots. Selenium in formic acid extracts (80 ± 3%) was present as selenopeptides with Se-S bonds and selenium-PC complexes (selenocysteinyl-2-3-dihydroxypropionyl-glutathione, seleno-phytochelatin2, seleno-di-glutathione). An analytical method using HPLC-ICPMS to de...

elemental diets have been used widely in the treatment of gastrointestinal disorders, especially with the management of crohn's disease. this modality of diets provide all essential nutrients, and contain protein in the form of free amino acids that are theoretically easily absorbed. a high output ileostomy is a rare complication of surgery that is difficult to treat. treatments include anti-di...

Estimates of the relative abundances of the elements in the solar system played an important role in establishing the malor processes of stellar nucleosynthesis Subsequently, it became legitimate to use nucleosynthesis methods to interpolate poorly known elemental abundances, but the experimental database has steadily improved and interpolation is less necessary now fThe SCI® indicates that thi...

The recent results show that the dependence of the elements' properties on the nuclei charge has a four-dimensional structure. The geometrical interpretation of this structure results in a four-dimensional pyramidal representation of the periodic properties of elements, which have traditionally been presented on a plane since Mendeleyev's times. 1. INTRODUCTION. The question whether there is a ...

approved for the nutritional management of patients with pancreatic disease [1, 2]. Nutrition therapy with elemental diets has been reported to significantly reduce mucosal inflammation and improve clinical and endoscopic disease activity and mucosal cytokine levels when used as a first-line therapy of Crohn’s disease [3, 4]. Prior studies with enterally administered elemental diets have also r...
