During hind limb unloading (HU), the soleus is often in a shortened position and the natural physiological stimulus of muscle spindles is altered, such that muscle spindle activity also changes. Using isolated spindle conditions, the present study investigates the electrophysiological activity and ultrastructure of muscle spindles following HU. Results show(More)
Using TiO<inf>2</inf> from the hydrolysis of TiOSO<inf>4</inf> as the precursor, and polystyrene (PS) as the template, TiO<inf>2</inf>/PS complex nanoparticles were successfully prepared through Layer-by-Layer self-assembly method. Then erased PS by heating, thus hollow sphere TiO<inf>2</inf> was attained. The synthesized materials were characterized by SEM(More)
To determine whether the neuronal activity of the spindle cord in muscle spindle afferent pathways is altered after a period of hindlimb unloading (Hu), and after recovery, we focused on c-Fos-immunoreactivity in the spinal cord evoked by excitation of the muscle spindle in normal gravity and after 3, 7, and 14 days of Hu, and after 14 days of Hu with an(More)
To investigate the effects of prenatal stress (PNS) on high-voltage-activated (HVA) Ca2+ channel and delayed rectifier potassium currents (I(KD)) of freshly isolated rat offspring hippocampal CA3 pyramidal neurons, the pregnant rats of PNS group were exposed to restraint stress and patch clamp technique of whole-cell mode was employed to record HVA Ca2+ and(More)
The static component of the spindle potential provoked during stretch of isolated muscle spindles of the frog was reversed during the application of depolarizing currents ranging from 0.2 to 5 nA in normal Ringer solution and also in Na+-free Ringer solution. In the same range of current intensities, spontaneous rhythmic hyperpolarizations due to(More)
This paper describes spectra of quasar candidates acquired during the commissioning phase of the Low-Resolution Spectrograph of the Hobby-Eberly Telescope. The objects were identiÐed as possible quasars from multicolor image data from the Sloan Digital Sky Survey. The 10 sources had typical r@ magnitudes of 19È20, except for one extremely red object with r@(More)
