moringaceae, a monogeneric family in capparales (glucosinolate-containing species), includes 14 species. one of them is moringa peregrina (forssk.) fiori., a small tree, which grows in south east of iran. volatile constituents of seed coat and stem of m. peregrina were determined by gc and gc/ms. moreover, extracts of seed and different cultured cells were analyzed by tlc and gc. three volatile...

If it were possible to clone in vitro cells of any type, at any stage of differentiation, from an extensively characterized animal such as the mouse, many areas of cell biology would benefit. Indeed, it would be even more helpful if these cells could subsequently be restored to their normal in vivo phenotype whenever required. Here, we describe a step on the pathway to such an idealized "clonab...

Absorption cross-sections and quantum yields for NO2 production (ΦNO2) are reported for gaseous methyl, ethyl, n-propyl, and isopropyl nitrate at 294 K. Absorption cross-sections in the wavelength range of 240-320 nm agree well with prior determinations. NO2 quantum yields at photoexcitation wavelengths of 290, 295, and 315 nm are unity within experimental uncertainties for all of the alkyl nit...

Farmstead Cheddar cheeses with natural bandage wrappings have a distinctive flavor profile that is appealing to many consumers. An earthy/bell pepper (EBP) flavor has been previously recognized in some of these cheeses. This study characterized the alkylmethoxypyrazine compounds causing EBP flavor in Farmstead Cheddar cheeses. Eight cheeses were divided into inner, outer, rind, and wrapper sect...

Postoperative nausea, a common complication in patients receiving general anesthesia, was studied in this randomized investigation to compare the efficacy of 70% inhaled isopropyl alcohol and intravenous ondansetron. For the study, 100 healthy women, ASA physical status I or II, scheduled for outpatient gynecologic laparoscopic procedures randomly received 4 mg of intravenous ondansetron or iso...

Using alcohols have been recommended for disinfecting and prevention of infections. The present study has been carried out with the aim to determine and compare the efficacy of alcohol Isopropyl and Ethanol (alcohol Ethylic) in reducing contamination of medical check-up instruments. This semiexperimental study has been carried out to compare the influence of two types of alcohols on the medical...
