AI Article Synopsis

  • The study examined how different light sources (xenon vs. sulfur lamps) affect the growth of cotton plants (Gossypium hirsutum cv. Xuzhou 142).
  • Utilization of sulfur lamps was found to reduce excessive elongation of the hypocotyl and enhance the growth of epidermis and cortex cells.
  • The results indicated that sulfur lamp illumination resulted in more branches, buds, and bolls, promoting better conditions for cotton yield production.

Article Abstract

Experiments were carried out with cotton (Gossgpium hirsutum cv. Xuzhou 142) plants to study the effects of illumination with xenon and sulfur lamp on development of cotton plants. The results showed that, compared with xenon lamp, illumination with sulfur lamp inhibited excessive elongation of hypocotyl via promotion of longitudinal elongation of epidermis and cortex cells, increased the numbers of branches, buds and bolls significantly. It suggested that illumination with sulfur lamp rendered cotton photomorphogenesis more favorable to yield formation.

One method for the colorimetric detection of hydrogen peroxide vapor is based on a titanium-hydrogen peroxide complex. A color changing material based on a titania hydroxypropyl cellulose thin film was initially developed. However, as this material dries, the sensitivity of the material is significantly reduced.

Visual detection of HO and glucose by HBcAb-HRP fluorescence-enhanced CdTe QDs/CDs ratiometric fluorescence sensing platform.

This study presents the development of a sensitive and simple enhanced ratiometric fluorescence sensing platform in the consist of CdTe quantum dots (QDs), carbon dots (CDs), and hepatitis B core antibody labeled with horseradish peroxidase (HBcAb-HRP) for the visual analysis of HO and glucose. The sulfur atoms in HBcAb-HRP have a strong affinity for Cd(II), which effectively enhances the fluorescence intensity of the CdTe QDs due to the generation of more radiative centers at the CdTe/Cd-SR complex. In the presence of HO, the Cd-S bonds are oxidized to form disulfide products and results in linear fluorescence quenching, while CDs maintain stable.

Purpose: The purpose of this study was to investigate the effect of gas tamponade on microvascular changes in patients with rhegmatogenous retinal detachment (RRD), who underwent pars plana vitrectomy (PPV), using optical coherence tomography angiography (OCTA).

Methods: Participants in this study were 48 patients with RRD, who were treated with PPV and gas tamponade without internal limiting membrane peeling. All participants underwent slit-lamp examination, fundoscopy, spectral domain-optical coherence tomography and optical coherence tomography angiography at month 6 postoperatively.

The present study was designed to develop a systematic understanding of the role that lipid-associated membrane proteins (LAMPs) may play in the virulence of this pathogen. Bioinformatics tools were used to identify 146 predicted membrane proteins and lipoproteins in the proteome.
