a-Tocopherol (a-TC) and a-TC/cyclodextrin (CD)–inclusion complex (IC) incorporated electrospun poly(lactic acid) (PLA) nanofibers (NF) were developed via electrospinning (PLA/a-TC–NF and PLA/a-TC/g-CD–IC–NF). The release of a-TC into 95% ethanol (fatty food simulant) was much greater from PLA/a-TC/g-CD–IC–NF than from PLA/a-TC–NF because of the solubility increase in a-TC; this was confirmed by...

Background—The myocardial uptake of Tc-sestamibi is attenuated by dobutamine stress, resulting in underestimation of ischemia. N-Ethyl-N-ethoxy-dithiocarbamato-N-Tc (Tc-N-NOET) is a new Tc-labeled perfusion agent that is highly extracted by the myocardium by a mechanism different from that defined for Tc-sestamibi. We therefore hypothesized that Tc-N-NOET uptake would not be attenuated by dobut...

There are two conflicting theories of how plasma vitamin B12 (B12) is transported in man: (a) by two distinct transport proteins, transcobalamins I and II (TC I and II), each having a specific role and time of function; and (b) by three active transport proteins, TC I, II, and III, that take up B12 randomly in proportion to the unsaturated amounts of each. To test these theories a man was given...

Little is known about the association between total cholesterol (TC) and all-cause mortality in the elderly (especially the very elderly). Here we examined the association between TC and all-cause mortality in 207 very elderly (85-year-old) participants. In 2003, we performed a baseline laboratory blood examination, and blood pressure (BP) and body mass index (BMI) measurements, and lifestyle q...

We define and develop a homotopy invariant notion for the topological complexity of map f:X?Y, denoted TC(f), that interacts with TC(X) TC(Y) in same way cat(f) cat(X) cat(Y). Furthermore, TC(f) satisfy inequalities as cat(X). compare it to other invariants defined papers [15], [16], [17], [18], [20]. apply studying group homomorphisms f:H?G.

tetracyclines (tcs) are broad-spectrum antibiotics that are used widely in veterinary medicine. the present study was carried out to trace the residues of oxytetracycline (otc) and tetracycline (tc) in pasteurized milk that is marketed in tehran with the use of a high performance liquid chromatography (hplc). ninety milk samples were collected during five sequential days from the products of si...

 Parathyroid adenoma involving a single parathyroid gland is the underlying cause of 80-85% of primary hyperparathyroidism (PHPT). Skeletal system is significantly affected by PHPT. Brown tumors are known to have affinity for 99mTc-MIBI. We report a rare case of PHPT presenting with diffuse bony pain, high calcium level and significantly elevated alkaline phosphatase level. 99m<...

Tetracyclines (TCs) are broad-spectrum antibiotics that are used widely in veterinary medicine. The present study was carried out to trace the residues of oxytetracycline (OTC) and tetracycline (TC) in pasteurized milk that is marketed in Tehran with the use of a High Performance Liquid Chromatography (HPLC). Ninety milk samples were collected during five sequential days from the products of si...

The reaction of the Tc(II) nitrosyl complex (Bu(4)N)[Tc(NO)Cl(4)] with Di-(2-picolyl)(NEt)amine in methanol yields the neutral complex [Tc(NO)Cl(py-N(Et)-py)]. The reaction of the Tc(I) nitrosyl complex [Tc(NO)Cl(2)(HOMe)(PPh(3))(2)] with this tridentate ligand yields cationic [Tc(NO)Cl(py-N(Et)-py)(PPh(3))]Cl. These two complexes have been structurally characterized. The reaction of [Tc(NO)Cl(...
