Photoelectrochemical/Colorimetric Dual-Mode Specific Detection of Based on the Enzymatic Reaction Triggered by Catalase from Lysed Bacteria.

() is abundant in nature and frequently leads to various health issues. Bacteriophages as obligate intracellular parasites of bacteria have the ability to specifically identify and infect , causing bacterial lysis and the release of endogenous catalase (CAT). The released CAT triggers the conversion of HO into O and HO, resulting in a notable decrease in UV absorption at 570 nm and a concurrent surge in photocurrent.

Impact of diabetic kidney disease on post-operative complications after primary elective total hip arthroplasty: a nationwide database analysis.

Background: The high prevalence of diabetic kidney disease (DKD) in the United States necessitates further investigation into its impact on complications associated with total hip arthroplasty (THA). This study utilizes a large nationwide database to explore risk factors in DKD cases undergoing THA.

Methods: This research utilized a case-control design, leveraging data from the national inpatient sample for the years 2016 to 2019.

Enzymatic photoelectrochemical bioassay based on hierarchical CdS/NiO heterojunction for glucose determination.

The design and development of a 3D hierarchical CdS/NiO heterojunction and its application in a self-powered cathodic photoelectrochemical (PEC) bioanalysis is introduced. Specifically, NiO nanoflakes (NFs) were in situ formed on carbon fibers via a facile liquid-phase deposition method followed by an annealing step and subsequent integration with CdS quantum dots (QDs). The glucose oxidase (GOx) was then coated on the photocathode to allow the determination of glucose.

3D NiO nanoflakes/carbon fiber meshwork: Facile preparation and utilization as general platform for photocathodic bioanalysis.

Herein, we describe a customized approach for facile preparation of three-dimensional (3D) NiO nanoflakes (NFs)/carbon fiber meshwork (CFM) and its validation as a common photocathode matrix for photoelectrochemical (PEC) bioanalysis, which to our knowledge has not been reported. Specifically, 3D NiO NFs/CFM was fabricated by a sequential liquid phase deposition and annealing process, which was then characterized by scanning electron microscopy, X-ray photoelectron spectrum, UV-vis absorption spectra and N adsorption-desorption measurement. Sensitized by BiOI and incorporated with an alkaline phosphatase (ALP)/tyrosinase (TYR) bi-enzyme cascade system, a sensitive split-type cathodic PEC bioanalysis for the determination of ALP was achieved.

A voltammetric sensor based on reduced graphene oxide-hemin-Ag nanocomposites for sensitive determination of tyrosine.

A novel voltammetric sensor was designed and used for the determination of l-tyrosine (l-Tyr) by surface modification of a glassy carbon electrode with reduced graphene oxide-hemin-Ag (rGO-H-Ag) nanocomposites. The nanocomposites were synthesized by a facile one-pot hydrothermal method and characterized by means of transmission electron microscopy and Raman spectroscopy. The determination of l-Tyr was investigated by cyclic voltammetry and further quantified using differential pulse voltammetry.

An OFF-ON detection method for copper(ii) ions using a AgAu-NG nanocomposite modified electrode.

An OFF-ON detection method for Cu was developed at the AgAu bimetallic nanoparticle decorated nitrogen-doped graphene (AgAu-NG) nanocomposite modified electrode. The measurement was based on the copper-catalyzed oxidation of cysteamine (Cys) to regulate the oxidation peak current of Ag. In the absence of Cu, Cys can bind to the surface of AgAu-NG via the Ag-S or Au-S bond, thus leading to an obvious decrease of the oxidation peak current of Ag.

[Phylogeny of the genus Arundinaria based on nucleotide sequences of nrDNA ITS region].

The sequences of nrDNA regions of 17 species and Phyllostachys edulis (outgroup) sampled, which are of represent and type species for different taxa in the genus Arundinaria,were analyzed by PCR amplification and direct DNA sequencing. The phylogenetic trees generated from maximum parsimony analysis showed that the sampled bamboos were naturally monophletic, appearing that these species of the bamboos belong to the genus Arundinaria. The internal transcribed spacers (ITS) data indicated that the species were divided into two branches, one including A.

[Analysis of the inter-species relationships on lycoris Amaryllidaceae) by use of RAPD].

The fingerprints of 13 species in genus Lycoris were generated by use of RAPD method. Forty-one primers were screened from 520 random primers, and a total of 350 DNA fragments were amplified ranging from 0.3-3.

[Sequence of the ITS region of nuclear ribosomal DNA(nrDNA) in Xinjiang wild Dianthus and its phylogenetic relationship].

Xinjiang is a center of distribution and differentiation of genus Dianthus in China, and has a great deal of species resources. The sequences of ITS region (including ITS-1, 5.8S rDNA and ITS-2) of nuclear ribosomal DNA from 8 species of genus Dianthus wildly distributed in Xinjiang were determined by direct sequencing of PCR products.
