The antiseptic efficacy of ethanol, isopropanol, and n-propanol at 60%, 70%, and 89.5% (all vol/vol) was analyzed after 2, 3, or 4 min of application to the forehead, back, and abdomen of 180 volunteers by the use of a standardized swab sampling method. Results of recolonization by the aerobic skin flora of the upper arms and backs of 20 volunteers were compared 72 h after treatment with 0.5%, ...

Using FT-ESR coupled with pulse radiolysis the kinetics of hydrogen abstraction from 2-propanol by hydrogen and deuterium radicals were studied in aqueous solution. The rate constants were determined from the effective spin–spin relaxation times of the free induction decay of hydrogen or deuterium ESR lines by variation of the 2-propanol Ž . Ž . concentration. The rate constants k and k for H D...

The amyloid A4 or beta peptide is a major component of extracellular amyloid deposits that are a characteristic feature of Alzheimer's disease. We synthesized a series of peptide analogs of the A4/beta peptide which are progressively longer at their carboxyl termini, including 42- and 39-residue peptides which represent the major forms of the A4/beta peptide in senile plaque and the hereditary ...

Proteins must have specific conformations to function correctly inside cells. However, sometimes they adopt the wrong conformation, causing dysfunction and disease. A number of amyloid diseases are caused by misfolded proteins that form amyloid fibrils. One such disease is Alzheimer's disease (AD). The protein involved in this deadly disease is the amyloid β (Aβ) peptide. The formation of solub...

The impact of feedstock impurities on catalytic process is among the crucial issues for processing real raw materials. A and model 92%-bioethanol contaminated with 0.03–0.3% mol 1-propanol or 2-propanol were used to make ethylene a proprietary alumina catalyst in isothermal flow reactor. We proposed formal kinetic describe impure bioethanol conversion byproducts it evaluate multi-tubular reacto...
