In addition, an oscillating ratio of tau(t)/tau(q) with the increasing n(2D) was predicted in the model. (C) 2010 American Institute of Physics. [doi:10.1063/1.3467520]“
“Drug-induced lupus is defined as a lupus-like
syndrome temporally related to continuous drug exposure which resolves after discontinuation DMH1 of the offending drug. Newer biological agents such as interferons (IFN) and anti-tumor necrosis factor-alpha therapies have been involved in the induction of lupus-like syndromes. Prompt recognition and discontinuation of the suspected drug are associated with excellent outcomes in most cases. In this article, we present the case who developed lupus during therapy with pegylated-IFN alpha-2b for chronic hepatitis B virus infection after 8 months.”
“A novel approach to self-assembled and shell-crosslinked (SCL) micelles from the diblock copolymer poly(L-lactide)-block-poly(L-cysteine) to be used as drug and protein delivery
carriers is described. Rifampicin was used as a model drug. The drug-loaded SCL micelles were obtained by self-assembly of the copolymer in the presence of the drug in aqueous media. Their morphology and size were studied with dynamic light scattering and field emission scanning electron microscopy. The rifampicin loading capacity and encapsulation efficiency were studied with ultraviolet visible spectrophotometry. The drug-release rate in vitro depended
on the oxidizing and reducing Alvespimycin environment. Moreover, a straightforward approach to the conjugation of the copolymer with bovine serum albumin (BSA) was developed, and a gel electrophoresis test demonstrated that this conjugated BSA could be reversibly released from the copolymer substrate under reducing conditions. In conclusion, this L-cysteine copolymer can be used in drug delivery and in protein fixation and recovery. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 118: 1738-1742, 2010″
“The single crystals of tungsten bronze-type potassium lithium tantalate Selleckchem Momelotinib niobate doped with three concentrations erbium with good quality are grown using top-seed solution growth method. The unpolarized ultraviolet-visible-near infrared optical absorption spectra of these single crystals are measured at room temperature. The green and red upconversion emission properties are analyzed with respect to steady-state spectra and decay behaviors under 800 nm femtosecond laser excitation. The spectroscopic properties of Er3+ ions are studied on the basis of the Judd-Ofelt theory. 12 Er3+ ions absorption bands are observed ranging from 350 to 1650 nm, the lower limit is also the ultraviolet absorption edge of these crystals. The fluorescence branching ratio and radiative lifetime are calculated to support the upconversion mechanism.
