Elgemeie, G., H.; Zaghary, W., A.; Amin, K., M.; Nasr, T., M., 2008: A direct route to a new class of acrylamide thioglycosides. The preparation of a new class of acrylamide thioglycosides via one-pot reaction of the potassium 2-cyanoethylene-1-thiolate salts with 2,3,4,6-tetra-O-acetyl--D-gluco- and galactopyranosyl bromides has been studied. The E-configuration of these...

Haertelt, M.; Lyon, J.T.; Claes, P.; de Haeck, J.; Lievens, P.; Fielicke, Aé., 2012: Gas-phase structures of neutral silicon clusters. Vibrational spectra of neutral silicon clusters Si(n), in the size range of n = 6-10 and for n = 15, have been measured in the gas phase by two fundamentally different IR spectroscopic methods. Silicon clusters composed of 8, 9, and 15 atoms have...

Yang, D-Jing.; Shi, S.; Yao, T-Ming.; Ji, L-Nian., 2012: Cooperative folding of tau peptide by coordination of group IIB metal cations during heparin-induced aggregation. The group IIB elements, especially Cd(II) and Hg(II), are increasingly considered as potential environmental neurotoxins. This study demonstrates that the Alzheimer's tau fragment R2, corresponding to the second repeat of the microtubule-bind...

Al-Gazali, L.I.; Bakir, M.; Hamid, Z.; Nath, D.; Haas, D., 2001: Micromelic dwarfism--humerus, femur and tibia type. We report a baby with severe micromelic dwarfism characterized by severe shortening of the humeri, femora and tibiae with hypoplastic radii, ulnae and fibulae which are of normal shape. We suggest that this case is similar to the case reported by...

Pathiratne, A.; Puyear, R.L.; Brammer, J.D., 1986: A comparative study of the effects of benzene, toluene, and xylenes on their in vitro metabolism and drug-metabolizing enzymes in rat liver. Male Sprague-Dawley rats were injected ip with benzene, toluene, or a mixture of xylene isomers at 20 mmol hydrocarbon/kg daily for 3 days. The effects of administration of these hydrocarbons upon their own in vitro metabolism, as well as upon cyt...

Clausen, J., 1927: Chromosome number and the relationship of species in the genus Viola. Thirty species of Viola (belonging to the 4 sections, Nominium, Dischidium, Chamaemelanium, and Melanium) were investigated. "The haploid chromosome numbers are 6, 7, 10, 11, 12, 13, 17, 18, 20, 24, 26, 27, 30 and 36. They fall into groups of...

Three classes of TFTr variants of L5178Y/TK+/- -3.7.2C mouse lymphoma cells can be identified.sbd.large colony .lambda., small colony (.sigma.) and tiny colony (.tau.). The .sigma. and .lambda. mutants are detectable in the routine mutagenesis ass...

Kakuda, T.; Nozawa, A.; Unno, T.; Okamura, N.; Okai, O., 2000: Inhibiting effects of theanine on caffeine stimulation evaluated by EEG in the rat. In this study, the inhibiting action of theanine on excitation induced by caffeine at the concentration regularly associated with drinking tea was investigated using electroencephalography (EEG) in rats. First, the stimulatory action by caffeine i...

Mirski, R.; Dziurka, D.; ecka, J., 2005: The effect of pressing time on properties of particleboards resinated with phenol-formaldehyde resin modified with polyols. The study investigated the effect of modification of phenolic resin with polyols such as ethylene glycol, propylene glycol, butylene glycol and glycerol on the possibility to shorten pressing time for particleboards manufactured with the use of su...
