A retrospective analysis was conducted on 10 patients admitted to our hospital between August and September 2023 due to two incidents of acute HS poisoning. The first incident involved fishermen working in a fishing cabin (6 patients), while the second involved sanitation workers during sewer maintenance (4 patients).

The unique advantage of neutral interface lies in its ability to create anisotropic particles with surface patterns. The resulting unique polymer particles exhibit deformability under swelling, coupled with excellent spreadability and optical properties.

In this study, we used the CiteSpace software to visualize and analyze 5809 documents from the core database of Web of Science from 1995 to 2023, covering four aspects: descriptive statistics, network collaboration, research hotspots, and thematic evolution analysis. The number of studies in the field of dual carbon is in an explosive growth stage and China and the Chinese Academy of Sciences have become the core country and institution for research, respectively, in this field.

Janus nano-objects (JNOs) with asymmetric polymer brushes are one unique material of them, which consist of a polymeric or inorganic core and asymmetric polymer chains coated on the core. Combining the properties of nanomaterials, asymmetric structures and flexible polymer brushes, hairy JNOs have shown great potential in interfacial compatibilization, interfacial catalysis, oil-water separation and drug delivery.

Herbal medicines are medicinal materials or preparations derived from plants and are widely used in the treatment of metabolic diseases due to their good curative effects and minimal side effects. Recent studies have shown that gut microbiota plays an important role in the herbal treatment of metabolic diseases.

In this study, a facile yet versatile route is developed to prepare anisotropic MCMPs by combining neutral interface-guided 3D confined self-assembly (3D-CSA) of block copolymer (BCP) with a self-templated direct carbonization strategy. This route enables pre-engineering BCP into microparticles with oblate shape and hexagonal packing cylindrical mesostructures, followed by selective crosslinking and decorating of their continuous phase with functional species (such as platinum nanoparticles, Pt NPs) via in situ growth.

Generally, nanostructured polymer particles are prepared by 3D confined self-assembly (3D-CSA) of block copolymers (BCPs), while micelles are obtained through self-assembly of BCPs in dilute solutions. Herein, a facile yet robust strategy is developed to regulate the assembled structures of BCP, poly(styrene-block-4-vinylpyridine) (PS-b-P4VP), from nanostructured particles to micelles. The assemblies are prepared by an emulsion-solvent diffusion-induced self-assembly route, which is conducted by dialysis.

We report a 51-year-old Chinese woman who, with histories of SLE for 14 years and disseminated talaromycosis for 4 years, occurred partial intestinal obstruction that was demonstrated to be caused by Talaromyces marneffei infection. The randomly amplified polymorphic DNA results of paraffin-embedded tissues from both the present episode and the previous infection suggested that the present infection was a recurrent.

Purpose: Our aim was to study calcium overload-induced apoptosis and its relation to reactive oxygen species (ROS) in rat C6 glioma cells after sonodynamic treatment (SDT).
Materials And Methods: Hematoporphyrin monomethyl ether (HMME) was used as the sonosensitizer. The concentration of intracellular Ca(2+) ([Ca(2+)](i)) was measured by fluorometry.
Purpose: It was the aim of our study to evaluate the in vitro activities of tetracycline (TET), erythromycin (ERY) and levofloxacin (LVX) alone and in dual combinations against ureaplasmas.
Methods: The minimum inhibitory concentrations (MICs) of 51 ureaplasmal strains were determined by microdilution assay.
Results: TET was the most active when the antibiotics were used alone.

Objective: To study the genome sequence of hepatitis A virus L-A-1 strain which has been applied for live attenuated vaccine production in China, to compare with other HAV strains, to understand some characteristics of L-A-1 strain, and to find the mechanism of attenuation and cell adaptation.
Methods: Genome fragments were prepared by antigen-capture PCR from infected cell (2BS), PCR products were cloned into T vector, sequenced and analyzed by using bioinformatics program.
Results: Analysis of the genomic sequences(nt 25-7,418) showed that the open reading frame contains 6,675 nucleotides in length encoding 2,225 amino acids.
