Resistance (R) factor-mediated streptomycin (Sm) resistance differs from classical, high-level, chromosome-borne Sm resistance in its dominance over sensitivity and in the level of its effectiveness (in Escherichia coli approximately 25 mug/ml versus >2,000 mug/ml). In addition, an R factor-containing strain, unlike high-level Sm-resistant bacteria, showed an inoculum effect with respect to its...

A number of single fibres were isolated by dissection of four bovine masseter (ma) muscles, three rectus abdominis (ra) muscles and eight sternomandibularis (sm) muscles. By histochemical criteria these muscles contain respectively, solely slow fibres (often called type I), predominantly fast fibres (type II), and a mixture of fast and slow. The fibres were analysed by conventional sodium dodec...

Studies have shown that different exercise ways are of the most important factors that affect cardiovascular risk factors and hematological parameters. This present paper aims to study the effects of two methods of endurance and resistance training on lipid profiles, heart rate, and hematological parameters in obese male students. 36 obese students were purposefully selected and randomly divi...

background and objectives: the prevalence of diabetes mellitus (insulin resistance) in individuals with down's syndrome is more than healthy people, which is possibly because of the high prevalence of obesity among them. adiponectin is one of adipose tissue-secreted adipocytokines, which plays a role in pathogenesis of obesity and insulin resistance. this study was carried out with the aim of d...

It is unknown whether MIRU-VNTR (Mycobacterial Interspersed Repetitive Unit-Variable Number of Tandem Repeat) is associated with drug resistance of Mycobacterium tuberculosis. The purpose of this study was to explore the ability of 24 MIRU loci to predict the drug resistance of Isoniazid (INH), Rifampicin (RFP), Streptomycin (SM), Ethambutol (EMB) and Pyrazinamide (PZA). We collected the drug r...

background and objectives: it has been shown that a bout of jumping exercise with weighted vests increases the subsequent countermovement jump height. however, it is not clear whether the improvement in jump height is due to the enhancement of joint power or due to other mechanisms such as neural adaptations. methods: to investigate this dichotomy, we tested the acute neuromechanical changes fo...

OBJECTIVE Interleukin (IL)-18 is associated with obesity, insulin resistance, and cardiovascular disease. The present study compared 1) IL-18 in adipocytes versus stromal vascular (SV) cells, 2) IL-18 in plasma and adipose tissue (AT) in obese versus lean subjects, and 3) IL-18 in plasma, AT, and skeletal muscle (SM) in obese subjects after weight loss. SUBJECTS AND METHODS At baseline, plasm...

abstract       background and objectives: diabetes induced oxidative stress plays an important role in pathological damage to the heart and liver by increased production of extracellular matrix. it is thought that the use of medicinal plants, particularly portulaca oleracea. l and regular exercise are effective. the aim of this study was to evaluate the effects of portulaca oleracea. l consumpt...

Background: The purpose of the present investigation was to study the possible differences between young and elderly individuals regarding muscle damage, position sense, and oxidative stress biomarkers in response to resistance eccentric-biased exercise. Methods: Ten young and 10 elderly individuals performed a bout of resistance exercise (i.e., squat exercise). Muscle damage indices (i.e., iso...

The global threat posed by drug-resistant strains of Mycobacterium tuberculosis demands a greater understanding of the genetic basis and molecular mechanisms that govern how such strains develop resistance against various antituberculous drugs. In this report, we examine a new genetic basis for resistance to one of the oldest and most widely used second-line drugs employed in tuberculosis thera...
