The catalytic properties of microporous zeolite catalysts were evaluated in the synthesis of decyl glucoside from glucose with 1-decanol by direct glucosidation. The effects of the acidic properties and pore structure of the zeolite catalysts on the glucose conversions and decyl glucoside yields were investigated. The conversions of glucose on the H+ ion-exchanged FAU, MFI, and BEA zeolite cata...

Peanut allergy is a significant health problem because of the frequency, the potential severity, and the chronicity of the allergic sensitivity. Serum IgE from patients with documented peanut hypersensitivity reactions and a peanut cDNA expression library were used to identify clones that encode peanut allergens. One of the major peanut allergens, Ara h I, was selected from these clones using A...

We have demonstrated previously that 1-0-D-arabinofuranosylcytosine (ara-C) incorporates specifically in cellular DMA and that the formation of (ara-C)DNA correlates significantly with inhibition of DMA synthesis and loss of clonogenic survival. Similar results have been obtained with 9-0-D-arabinofuranosyladenine (ara-A). These findings have been extended by studying the incorporation of ara-C...

BACKGROUND In children, a diagnosis of peanut allergy causes concern about accidental exposure because even small amounts of peanut protein could trigger an allergic reaction. Contamination of toys, books or other items by peanut butter in areas where individuals have eaten may occur in hospital waiting rooms and cafeterias. It is not known if hospital cleaning wipes are effective in removing p...

We examined the hypothesis that processes related to DNA recombination and repair are involved in learning and memory. Rats received intracerebroventricular (i.c.v.) infusions of the antimetabolite 1-beta-D-arabinofuranosylcytosine triphosphate (ara-CTP) or its precursor cytosine arabinoside (ara-C) 30 min prior to conditioned taste aversion (CTA) training. Both ara-CTP and ara-C caused signifi...

A structural study of a hierarchical zeolite X, which is similar to the one first synthesized by Inayat et al.,12 was performed using transmission electron microscopy imaging and diffraction. Evidence is provided, by comparison to simulations, that this material is an intergrowth of FAU and EMT and a conceptual model is presented for the growth of the FAU material with a small fraction of EMT i...

Zeolites with the faujasite structure (FAU) are extensively used as catalysts and in gas separation. A detailed knowledge of their structure, particularly the positions of extra−framework cations in the case of gas adsorption, is therefore central to understanding their performance. Typically zeolites X (Si/Al ~.1.1−1.5) and Y (Si/Al ~5−11) are used. A common assertion of structural determinati...

9-beta-d-Arabinofuranosylhypoxanthine 5'-monophosphate (ara-HxMP) significantly controlled the development of encephalitis produced by deoxyribonucleic acid viruses in mice. In most experiments the activities of ara-HxMP and 9-beta-d-arabinofuranosyladenine (ara-A) were determined simultaneously. In the intracerebral (target organ) and intravenous therapy experiments, ara-HxMP had a pronounced ...
