The L-arabinose-binding protein (ABP) of Escherichia coli consists structurally of two distinct globular domains connected by a hinge of three separate peptide segments. Arabinose is bound and completely sequestered within the deep cleft between the two domains. With reduced affinity, ABP also binds D-galactose (approximately 2-fold reduction) and D-fucose (approximately 40-fold reduction). Exp...
Twelve peptides derived from melanocyte differentiation proteins and cancer-testis Ags were combined and administered in a single mixture to patients with resected stage IIB, III, or IV melanoma. Five of the 12 peptides included in this mixture had not previously been evaluated for their immunogenicity in vivo following vaccination. We report in this study that at least three of these five pept...

ناباروری به ناتوانی بیولوژیکی یک شخص در بارداری گفته می شود. این ممکن است ناتوانی یک زن برای داشتن یک دوران حاملگی کامل نیز تعریف شود. ناباروری زنان علل متفاوتی دارد که یکی از مهمترین آنها شکست های لانه گزینی است. یکی از مهمترین وقایع لانه گزینی واکنشهای بین مولکولی است. فاکتور مهارکننده لوکمیا یک سیتوکین گلیکوپروتینی است که اولین بار بخاطر نقش تمایزی آن در تبدیل سلولهای لوکمی میلوئیدیm1 به ماک...
The perfluoroalkyl compounds (PFCs), perfluoroalkyl sulfonates (PFXS) and perfluoroalkyl carboxylates (PFXA) are environmentally persistent and recalcitrant towards most conventional water treatment technologies. Here, we complete an in depth examination of the UV-254 nm production of aquated electrons during iodide photolysis for the reductive defluorination of six aquated perfluoroalkyl compo...
In order to detect possible m5C photoproducts, highly purified rat liver DNA-cytosine methyltransferase was used to specifically generate m5C with a radioactive methyl group. When these DNAs were subjected to a large dose (10 kJ/m2) of 254 nm or 302 nm ultraviolet light (UVB) to enhance the yield, two labeled photoproducts were detected and isolated by reverse phase HPLC after formic acid hydro...
Both the photolysis products and absorption of khnology cross sections of the C1O dimer, C1OOC1, are important to the photochemistry of the polar winter. In this work dimer photolysis was studied at the wavelength 254 mn, at 195 K. The dimer was prepared by the photolysis of C120 at 254 nm. As ditner appeared, it absorbed a significant fraction of the 254 nm light, By following the rate of phot...
