background and objectives: staphylococcus aureus is a versatile organism causing mild to life threatening infections. the major threat of this organism is its multidrug resistance. the present study was carried out to investigate in - vitro activity of conventional antibiotics routinely prescribed for methicillin resistant s. aureus (mrsa) and methicillin sensitive s. aureus (mssa) infections i...

It has been known for 50 years or longer that much disease is caused by reactive oxygen species (ROS). At an international meeting of the World Health Organization in the mid-1960s, the distinguished Russian toxicologist, Professor Sanojki, presented a major treatise on the ‘rusting diseases’, a phrase not understood by many American and European delegates, but intended to mean diseases attribu...

SIEGEL, J. M., M. B. STERMAN AND S. ROSS. Automatic detection and operant reinforcement of slow potential shifts.PHYSIOL. BEHAV. 23(2) 411-413, 1979.—A technique for the automatic detection and operant reinforcement of slow potential (SP) changes is described. The SP shift detection device contains 3 inhibit channels to control sources of potential artifact including: vertical EOG, horizontal E...

Antimicrobial resistance results in increased morbidity, mortality, and costs of health care. Prevention of the emergence of resistance and the dissemination of resistant microorganisms will reduce these adverse effects and their attendant costs. Appropriate antimicrobial stewardship that includes optimal selection, dose, and duration of treatment, as well as control of antibiotic use, will pre...

Breeding programs aiming at developing new nematode-resistant rootstocks are important because current rootstocks with adequate nematode resistance tend to have other undesirable viticultural characteristics (excessive vigor, excessive potassium uptake, poor resistance to phylloxera, rooting difficulty, inadequate zinc absorption). In this paper the authors develop a technique for evaluating re...

We observed that radio-frequency (rf) irradiation significantly enhances the c-axis resistance near and below the superconducting transition of the CuO2 layer in contact with a normal-metal electrode on the surface of Bi2Sr2CaCu2O8+x single crystals. We attribute the resistance anomaly to the rf-induced charge-imbalance nonequilibrium effect in the surface CuO2 layer. The relaxation of the char...

Retapamulin had the lowest rate of spontaneous mutations by single-step passaging and the lowest parent and selected mutant MICs by multistep passaging among all drugs tested for all Staphylococcus aureus strains and three Streptococcus pyogenes strains which yielded resistant clones. Retapamulin has a low potential for resistance selection in S. pyogenes, with a slow and gradual propensity for...

Publishing in economics proceeds much more slowly on average than the natural sciences, and other social sciences finance. It is even relatively slower at extremes. We demonstrate that of lag, especially extremes, arises from authors' dilatory behavior revising their work. The marginal product an additional round re-submission top journals productive subsequent citations; but conditional re-sub...
