The change in swim performance over time has been investigated for freestyle, but not for other strokes, such as in the medley. The aim of the study was to examine changes in 200 m and 400 m swim performances in medley swimmers at national (Switzerland) and international level (world championship finals) from 1994 to 2011. The 200 m and 400 m freestyle performances were also analyzed for compar...

The rel gene is responsible for the maintenance of the level of (p)ppGpp in bacteria under nutrient starvation. This phenomenon known as stringent response plays an important role during survival of the microorganisms in stationary phase. We have cloned 1.6 kb upstream sequence of rel gene of Mycobacterium tuberculosis in a shuttle vector pSD5B containing promoterless lacZ gene and promoter act...

conclusions this study demonstrated the specificity and sensitivity of the pcr-sscp method for finding mutations in the gyra gene. due to the sensitivity of most isolates to ciprofloxacin, this antibiotic should be considered an appropriate drug for the treatment of related diseases. background during the past several years, nontuberculous mycobacteria (ntm) have been reported as some of the mo...

Ocean-atmosphere simulations corroborate the relationship between tropical Atlantic subsurface heat and salt storage driven by Salinity Maximum Water (SMW) deglacial perturbations of Meridional Overturning Circulation (AMOC). Whether AMOC variability last glacial cycle affected SMW export into West remained yet elusive. In order to assess sensitivity hydrography during abrupt rapid climatic oce...

Postprandial hypotension (PPH) occurs frequently in the elderly; the magnitude of the fall in blood pressure (BP) is related to the rate of glucose entry into the duodenum during intraduodenal glucose infusion and spontaneous gastric emptying (GE). It is unclear if glucose concentration affects the hypotensive response. Gastric distension may attenuate PPH; therefore, meal volume could influenc...

Amplification of a specific, 500-bp fragment from Mycobacterium bovis isolates and use of the fragment to differentiate between Mycobacterium tuberculosis and M. bovis was previously reported (J. G. Rodriguez, G. A. Meja, P. Del Portillo, M. E. Patarroyo, and L. A. Murillo, Microbiology 141:2131-2138, 1995). In the present study, 30 M. bovis isolates from Sardinian cattle were examined for the ...

Before the diagnostic potential of 24-hour non-invasive BP measurement can be assessed, the accuracy of ambulatory recorders must be established, and normal reference values determined. The accuracy criteria of four ambulatory BP measuring systems (the SpaceLabs 90207, the Novecor DIASYS 200, the Takeda TM-2420 and the Del Mar Avionics Pressurometer IV) have been assessed according to the Briti...

accurate and rapid diagnosis of human cytomegalovirus (hcmv) disease in immunocompromised patients has remained as a challenge. quantitative competitive pcr (qc-pcr) methods for detection of hcmv in these individuals have improved the positive and negative predictive values of pcr for diagnosis of hcmv disease. in this study we used qc-pcr assay, using a co-amplified dna standard, to quantitate...

Piezophilic Desulfovibrio profundus strain 500-1 was isolated in the Japan Sea from a sediment layer at 500-m depth under a water column of 1,000 m. Here, we report the genome sequence of this strain, which includes a 4,168,905-bp circular chromosome and two plasmids of 42,836 bp and 6,167 bp.
