Chronic stroke survivors have an increased incidence of falls during walking, suggesting changes in dynamic balance control post-stroke. Despite this increased incidence of falls during walking, balance control is often studied only in standing. The purpose of this study was to quantify deficits in dynamic balance control during walking, and to evaluate the influence of visual feedback on this ...

We report on WSRT observations of HI and OH absorption at a redshift of z = 0.885 towards the radio lens PKS 1830−21. The mm wave transitions of several molecular species have already been observed in absorption towards PKS 1830−21 at this redshift. At mm wavelengths the source structure is dominated by two extremely compact components, the northeast (NE) and southwest (SW) components. At lower...

Cardiac output (CO) and regional blood flow to various tissue were measured by means of gamma-labeled plastic microspheres (15 +/- 3 micrometers) injected into the left ventricle during 30-min infusion of l-norepinephrine (NE:4 micrograms(kg.min)) or the same amount of saline (11 microliters/min per animal) in rats physically trained by 2-hr swimming in water of 32 (SW-32), 36 (SW-36), and 38 d...

Some freshwater (FW) teleosts are capable of acclimating to seawater (SW) when challenged; however, the related energetic and physiological consequences are still unclear. This study was conducted to examine the changes in expression of gill Na(+)-K(+)-ATPase and creatine kinase (CK) in tilapia (Oreochromis mossambicus) as the acute responses to transfer from FW to SW. After 24 h in 25 ppt SW, ...

Neural stem cells are of special interest due to their potential in neurogenesis to treat spinal cord injuries and other nervous disorders. Flow cytometry, a common technique used for cell sorting, is limited due to the lack of antigens and labels that are specific enough to stem cells of interest. Dielectrophoresis (DEP) is a label-free separation technique that has been recently demonstrated ...

BACKGROUND The aim of this study is to assess and document the dimensions of the normal spleen measured on computed tomography (CT) images with the normal splenic volume measured by Cavalieri principle on CT images and thereby serve as a baseline for comparison in cases of splenomegaly using abdominal CT. To investigate the relationship between these changes and body mass index, gender, abdomin...

We report constant-volume and constant-pressure simulations of the thermodynamic and dynamic properties of the low-temperature liquid and crystalline phases of the modified Stillinger-Weber (SW) model. We have found an approximately linear temperature increase of the effective Gaussian width of the distribution of inherent structures. This effect comes from non-Gaussianity of the landscape and ...
