Degradation of Methylene Blue by Ozone Oxidation Catalyzed by the Magnetic MnFeO@CoS Nanocomposite.

In this study, the MnFeO@CoS magnetic nanocomposite was prepared by a two-step hydrothermal method and used to catalyze the ozone oxidation degradation of methylene blue. It was characterized by XRD, EDS, SEM, FT-IR, and XPS. The results showed that the introduction of CoS made MnFeO grow uniformly on CoS nanosheets, which effectively prevented the agglomeration of MnFeO.

A Pool of Bacterium-like Particles Displaying African Swine Fever Virus Antigens Induces Both Humoral and Cellular Immune Responses in Pigs.

Background/objectives: African swine fever (ASF), caused by African swine fever virus (ASFV), poses a significant threat to the global swine industry. This underscores the urgent need for safe and effective ASF vaccines.

Methods: Here, we constructed five bacterium-like particles (BLPs) that each display one of the five ASFV antigens (F317L, H171R, D117L, B602L, and p54) based on the Gram-positive enhancer matrix-protein anchor (GEM-PA) system.

Cholecystogastric fistula presenting as pyloric obstruction - a Bouveret's syndrome: A case report.

Background: Bouveret's syndrome is a rare (1%-4%) form of cholelithiasis characterized by gastric outlet obstruction. It presents mainly in elderly women with nausea, vomiting, and abdominal pain. On physical examination, common findings include dehydration signs such as tachycardia, decreased urine output, abdominal discomfort, and distention.

Metabolic resistance to pyrethroids with possible involvement of non-coding ribonucleic acids in Anopheles funestus, the major malaria vector in western Kenya.

Background: The resurgence of Anopheles funestus, a dominant vector of human malaria in western Kenya was partly attributed to insecticide resistance. However, evidence on the molecular basis of pyrethroid resistance in western Kenya is limited. Here, we reported metabolic resistance mechanisms and demonstrated that multiple non-coding Ribonucleic Acids (ncRNAs) could play a potential role in An.

AuNPs/GO/Pt microneedle electrochemical sensor for in situ monitoring of hydrogen peroxide in tomato stems in response to wounding stimulation.

Hydrogen peroxide (HO) is a critical signaling molecule with significant roles in various physiological processes in plants. Understanding its regulation through in situ monitoring could offer deeper insights into plant responses and stress mechanisms. In this study, we developed a microneedle electrochemical sensor to monitor HO in situ, offering deeper insights into plant stress responses.
