Article Synopsis
  • This study investigates the connection between salivary conductivity and body fluid status in patients undergoing intravenous hydration after an acute stroke.
  • Researchers measured salivary conductivity before and after hydration, finding a significant decrease in conductivity among all patients, with greater improvements in those with acute ischemic stroke.
  • A 20% reduction in salivary conductivity was linked to better early neurological outcomes, suggesting that monitoring salivary conductivity could help assess hydration status and recovery in stroke patients.

Conductive atomic force microscopy (C-AFM) was employed to perform conductivity measurements on a facet-specific CuO cube, octahedron, and rhombic dodecahedron and intrinsic Si {100}, {111}, and {110} wafers. Similar curves to those recorded previously using a nanomanipulator were obtained with the exception of high conductivity for the Si {110} wafer. Next, curves of different CuO-Si heterostructures were evaluated.

Article Synopsis
  • The study focused on creating a portable device to measure salivary conductivity as a non-invasive method for assessing fluid status in adults.
  • It involved 20 volunteers who underwent a 13-hour observation period that included 12 hours of water restriction followed by rapid rehydration.
  • Results showed that salivary conductivity increased during dehydration and decreased upon rehydration, correlating well with other fluid status indicators, suggesting the device can effectively screen for dehydration in healthy adults.

Purpose: To report a case of Paracentral acute middle maculopathy (PAMM) caused by severe internal carotid artery (ICA) stenosis and discuss the correlation between PAMM and ICA stenosis.

Case Description: A 67-year-old male patient presented with left acute blurred vision for 1 week. The best-corrected visual acuity of the left eye was 0.

ZnS particles were grown over CuO cubes, octahedra, and rhombic dodecahedra for examination of their facet-dependent photocatalytic behaviors. After ZnS growth, CuO cubes stay photocatalytically inactive. ZnS-decorated CuO octahedra show enhanced photocatalytic activity, resulting from better charge carrier separation upon photoexcitation.

A simple aqueous-phase synthesis of PbSe nanocubes with tunable sizes has been developed by first preparing a Na SeSO stock solution through dissolution of selenium powder in a solution of Na SO at 90-100 °C for 30 min, and adding part of this solution to a mixture of lead acetate and acetic acid at room temperature with stirring for only 5-8 min to complete the nanocrystal growth. Adjusting the volume of acetic acid and Na SeSO solution added enabled the size of the nanocrystals to be tuned, with average edge lengths of 13 to 121 nm attained. Changes in solution color revealed very different crystal growth rates for the 13 and 121 nm nanocubes.

Electrical conductivity properties of Ge {100}, {110}, {111}, and {211} facets have been measured by breaking Ge (100) and (111) wafers to expose {110} and {211} surfaces and contacting the different facets with tungsten probes. Ge {111} and {211} faces are far more conductive than the already conductive Ge {100} and {110} faces, matching with recent density functional theory (DFT) predictions. Asymmetric I-V curves resembling those of p-n junctions have been collected for the {110}/{111} and {110}/{211} facet combinations.

We report the transport and trapping behavior of 100 and 500 nm diameter nanospheres in a plasmon-enhanced two-dimensional optical lattice. An optical potential is created by a two-dimensional square lattice of gold nanostructures, illuminated by a Gaussian beam to excite plasmon resonance. The nanoparticles can be guided, trapped, and arranged using this optical potential.
