The changes of blood perfusion of contralateral testis after unilateral testicular torsion remain controversial. In this study, 28 New Zealand white male rabbits were randomly divided into five groups. Group A (n = 8), the control group, underwent a sham operation on the unilateral testis without inducing testicular torsion. In groups B, C, and D (n = 5 each), unilateral testicular torsion was ...

HALL, E. E., P. EKKEKAKIS, and S. J. PETRUZZELLO. Is the Relationship of RPE to Psychological Factors Intensity-Dependent? Med. Sci. Sports Exerc., Vol. 37, No. 8, pp. 1365–1373, 2005. Purpose: Although ample evidence shows that ratings of perceived exertion (RPE) are correlated with psychological variables, whether and how these relationships change as a function of exercise intensity remains ...

We present a simple and rapid method for measuring the acoustic energy density in microchannel acoustophoresis based on light-intensity measurements of a suspension of particles. The method relies on the assumption that each particle in the suspension undergoes single-particle acoustophoresis. It is validated by the single-particle tracking method, and we show by proper re-scaling that the re-s...

Glassy and elastomeric nematic networks with dye molecules present can be very responsive to illumination, huge reversible strains being possible. If absorption is appreciable, strain decreases with depth into a cantilever, leading to bend that is the basis of micro-opto-mechanical systems (MOMS). Bend actually occurs even when Beer's law suggests a tiny penetration of light into a heavily dye-...

Lipofuscin in the retinal pigment epithelium (RPE) is thought to be derived from phagocytosed photoreceptor outer segment disc membranes. Based on this hypothesis, one would predict that the rate of lipofuscin deposition in the RPE would be proportional to the density of photoreceptor cells in the retina. In previous studies it was demonstrated that specific loss of photoreceptor cells due to a...

We computationally show that metallic nanoslitsintegrated on Germanium metalsemiconductor-metal photodetectors show absorption enhancement up to 8 for TM-polarization in the communications C-band due to interference of horizontal surface plasmons. OCIS codes: 040.5160; 130.0250; 250.5403 Semiconductor industry has continuously scaled down electronic devices, significantly improving device leve...

The increasing availability of precipitation observations from space, e.g., from the Tropical Rainfall Measuring Mission (TRMM) and the forthcoming Global Precipitation Measuring (GPM) Mission, has fueled renewed interest in developing frameworks for downscaling and multi-sensor data fusion that can handle large data sets in computationally efficient ways while optimally reproducing desired pro...

The expression pattern of cyclin E during the cell cycle was studied in normal and tumour cells in culture and in tumour biopsies. This pattern was found to be abnormal in tumour cells. A triple immunostaining protocol, digital microscopy and image analysis were used to find the position of the individual cells in the cell cycle and to measure the nuclear cyclin E levels. In normal cells, the n...

background: cardiac rehabilitation is known as a powerful non-pharmacological approach for improving functional capacity, and left ventricular systolic function; however, some limited data have suggested an attenuation of the decline in diastolic function with this program. this study investigated the effect of high intensity aerobic exercise following coronary artery bypass surgery (cabg) on d...
