For evaluating N(2) fixation of diazotrophic bacteria, nitrogen-poor liquid media supplemented with at least 0.5% sugar and 0.2% agar are widely used for acetylene reduction assays. In such a soft gel medium, however, many N(2)-fixing soil bacteria generally show only trace acetylene reduction activity. Here, we report that use of a N(2) fixation medium solidified with gellan gum instead of aga...

BACKGROUND Postoperative ileus (POI) is a common complication following caesarean section. It impairs patients comfort; delays wound healing and prolong duration of hospital stay. Several methods have been used in the management of this condition with varying efficacy. Chewing gum postoperatively is a recent concept in the western world being advocated as a cost effective and comfortable manage...

the present article aims to conduct an ethnographic study of the confrontation between the local culture and global commodities in baneh. theoretically, this article suggests that confrontation with the global should be understood in relation to neoliberal market, identityand collective ideologies. thus,while carrying out a participant observation,we interviewed fifteen people in baneh. the res...

Root caries is not exclusive to older individuals. Any caries-prone patient having gum recession can develop root caries. However, the elderly are usually more vulnerable to root caries because of several conditions. First, older patients are more likely to experience gum recession. Gum recession exposes the root of the tooth, which is softer than the enamel-covered crown of the tooth. Conseque...

The petroleum ether extract of the oleo-gum-resin of Boswellia carteri Bird., the chloroformic successive extract of the oleo-gum-resin of Commiphora myrrha Engl. as well as the prepared volatile contents from both resins showed significant anti-inflammatory activity in carragennan-induced edema in rats. Phytochemical investigation of the volatile fractions was carried out using GC/MS and revea...

The effectiveness of 2 mg nicotine chewing-gum as an aid to stopping smoking was compared with a placebo containing 1 mg nicotine, but unbuffered, in a double-blind randomised trial. Of 58 subjects given the active gum, 27 (47%) were not smoking at one-year follow-up compared with 12 (21%) of the 58 subjects treated with placebo (p less than 0.025). By the most stringent criterion of outcome, 1...

OBJECTIVE To assess the need for, and potential uptake of, a contraceptive service within a genitourinary medicine (GUM) clinic. METHODS 544 women, median age 17 years (range 13-54) including 142 teenagers, attending the Fife GUM clinics serving a semirural population of 350,000 for the first time in the 12 month period from 1 September 1995 to 31 August 1996 were interviewed. RESULTS Contr...

The present work is the first part of a comprehensive study on the use of guar gum to improve delivery of microscale zero-valent iron particles in contaminated aquifers. Guar gum solutions exhibit peculiar shear thinning properties, with high viscosity in static conditions and lower viscosity in dynamic conditions: this is beneficial both for the storage of MZVI dispersions, and also for the in...

In the attempt to lower the sugar consumption in population is to exchange the number of sugar sweeteners which manufacture produced for used in foods, drinks and candy with non-sugar sweetener as xylitol. Xylitol is effective as noncariogenic substitutes for use in place of glucose. Objectives: A clinical trial was carried out to investigate the effect of sugar candy containing xylitol inhibit...
