Stereoacuity was determined for gratings and gabor patches as their orientation was varied. Acuity was constant for 1 c/deg and 2 c/deg gratings over the range 0-80 deg when it was expressed as positional shift at right angles to the grating orientation. The same was true of an 8 c/deg elongated gabor patch. However, the threshold disparity at right angles to the major axis of an oriented gauss...

Degenerin/epithelial Na(+) channels (DEG/ENaCs) are voltage-independent Na(+) or Na(+)/Ca(2+) channels expressed in many tissues and are needed for a wide range of physiological functions, including sensory perception and transepithelial Na(+) transport. In the nervous system, DEG/ENaCs are expressed in both neurons and glia. However, the role of glial vs. neuronal DEG/ENaCs remains unclear. We...

UNLABELLED Accumulating evidence suggests that neurotensin receptors (NTRs) play key roles in cancer growth and survival. In this study, we developed a simple and efficient method to radiolabel neurotensin peptide with (18)F for NTR-targeted imaging. METHODS The thiol-reactive reagent (18)F-(2-(2-(2-fluoroethoxy)ethoxy)ethylsulfonyl)ethane ((18)F-DEG-VS) was facilely prepared through 1-step r...

The role of cholesterol in the thermal adaptation of biological membranes is explored. Physical and chemical responses of membranes to acclimation temperature were evaluated using plasma membrane domains (basolateral and brush border) prepared from intestinal epithelia of 5- and 20 °C-acclimated rainbow trout (Oncorhynchus mykiss). Basolateral membranes (BLMs) exhibit perfect homeoviscous e...

Background: Microalgal lipid is a promising feedstock for biodiesel production. The aim of the present study was to investigate the effects of cultivation temperature on the growth and lipid accumulation properties of Nannochloropsis oculata microalgae. Methods: Nannochloropsis oculatacan grow in a wide range of temperatures (5 ~ 35°C). Late in the stationary growth phase of microalgae, bi...

Improved optical and mechanical properties are required for future infrared windows working in harsher thermal environments than today. Ameliorating the homogeneity of phase domain reducing size effective approaches enhancing transmittance hardness a nanocomposite. In this work, we reported that Gd2O3-MgO nanopowders were prepared by two different processes. The core–shell synthesized urea prec...
