Several mouse aldehyde dehydrogenases catalyze the detoxification of aldophosphamide, the pivotal metabolite of the prodrugs cyclophosphamide, mafosfamide, and other oxazaphosphorines. N-Isopropyl-p-formylbenzamide, a major metabolite of procarbazine, was found to be an excellent substrate (Km = 0.84 microM) for at least one of these enzymes, namely, mouse aldehyde dehydrogenase-2. The Km for m...

The aim of this study was to optimize topical nanoemulsions containing genistein, by means of a 23 full factorial design based on physicochemical properties and skin retention. The experimental arrangement was constructed using oil type (isopropyl myristate or castor oil), phospholipid type (distearoylphosphatidylcholine [DSPC] or dioleylphosphaditylcholine [DOPC]), and ionic cosurfactant type ...

BACKGROUND Terra-firma forme dermatosis, also known as Duncan's dirty dermatosis, is a benign skin condition that presents as dirt-like plaques in patients of all ages. PURPOSE We describe a series of ten patients that presented with terra-firma forme dermatosis. METHODS AND MATERIALS We reviewed PubMed for the following terms: dermatosis, Duncan's dirty dermatosis, isopropyl alcohol, terra...

We read with interest the recent article by Batalla et al. on the use of hand hygiene and antisepsis products among health care professionals and the relationship between these products and hand eczema. While we are in full agreement with the central message of the article and the authors’ algorithm for the management of patients with intolerance to alcohol-based products, we would like to add ...

BACKGROUND Many disinfectants have been used clinically in both single and combination applications, but there have been few studies on disinfective power according to sterilization sequence when using a combination of disinfectants. The purpose of this study was to evaluate the disinfective power of a combination of 70% isopropyl alcohol and 10% povidone-iodine (PVP-I) according to sterilizati...

The comparative in vitro skin permeability of diclofenac sodium through excised mouse skin from different common pharmaceutical vehicles like castor oil, olive oil, arachis oil, liquid paraffin, white soft paraffin melt, 3% sodium carboxymethyl cellulose (CMC) aqueous gel and isopropyl myristate (IPM), excluding other excipients was evaluated. Significantly (p < 0.05) higher flux of diclofenac ...

Isopropyl methanesulfonate (IPMS) is the most potent genotoxic compound among methanesulfonic acid esters. The genotoxic potential of alkyl sulfonate esters is believed to be due to their alkylating ability of the O6 position of guanine. Understanding the primary repair pathway activated in response to IPMS-induced DNA damage is important to profile the genotoxic potential of IPMS. In the prese...

Low concentrations of N-nitrosodimethylamine are metabolized in rodent and human liver by cytochrome P450IIE1, an activity competitively inhibitable by ethanol. In rodents coadministration of ethanol with N-nitrosodimethylamine results in increased tumorigenicity in extrahepatic organs, probably as a result of reduced hepatic clearance. To test this concept in a primate, the effects of ethanol ...
