Platelets and circulating CD34-positive cells have been reported to contribute to vascular repair (endothelial repair and developing atherosclerosis). And because hypertension is known to be a strong vascular impairment factors, it should also influence the respective numbers of these factors. To clarify the clinical importance of platelets on vascular repair, we conducted a cross-sectional stu...

Aggregative data infrastructures (ADIs) are information systems where organizations can find the tools to integrate their data sources to form uniform and richer information spaces of object metadata descriptions. Novel sustainable approaches for the realization of ADIs are based on the adoption of ADI enabling technologies which support the realization, maintenance and upgrade of ADIs and prom...

The fluorescent indicator chlortetracycline was used to estimate membrane-bound calcium in mild, untreated hypertensive patients (n = 39) and normotensive controls (n = 42). All participants were black. After incubation with chlortetracycline, platelet-rich plasma was centrifuged into a pellet and fluorescence was measured with a microspectrofluorometer. At an interval of 45 minutes mean fluore...

Here the spatial distribution of soil enzymatic properties in agricultural land was evaluated on a county-wide (567 km(2)) scale in Changwu, Shaanxi Province, China. The spatial variations in activities of five hydrolytic enzymes were examined using geostatistical methods. The relationships between soil enzyme activities and other soil properties were evaluated using both an integrated total en...

Protocol: To detect the 506 polymorphism, a 567 bp SMPD1 genomic fragment is amplified using sense (5'-AGTAGTCGACATGGGCAGGATGTGTGG-3') and antisense (5'-AGTAGTGTCGACTTGCCTGGTTGAACC AC AGC-3') primers. Dot-blot hybridization is performed using allele-specific oligonucleotides for 506-Arg (5'-ACTACTCCAGGAGCTCT-3') and for 506-Gly (5'-ACTACTCCGGGAGCTCT-3'), which are hybridized at 42°C and washed ...

Quasi-life tables, in which the data arise from many concurrent, independent, discrete-time renewal processes, were defined by Baxter (1994, Biometrika 81:567-577), who outlined some methods for estimation. The processes are not observed individually; only the total numbers of renewals at each time point are observed. Crowder and Stephens (2003, Lifetime Data Anal 9:345-355) implemented a forma...

Mild traumatic brain injuries (mTBIs) are common in contact sports. There is an association between mTBIs and altered motor function. BioSway technology measures individuals' balance using the Balance Error Scoring System (BESS). Prior to incorporating BESS testing in concussion protocol, other variables that influence the BESS test require review. The objective of this study is to determine if...
