Recent advances in nanomaterial-enabled chemiresistive hydrogen sensors.

With the growing adoption of hydrogen energy and the rapid advancement of Internet of Things (IoT) technologies, there is an increasing demand for high-performance hydrogen gas (H) sensors. Among various sensor types, chemiresistive H sensors have emerged as particularly promising due to their excellent sensitivity, fast response times, cost-effectiveness, and portability. This review comprehensively examines the recent progress in chemiresistive H sensors, focusing on developments over the past five years in nanostructured materials such as metals, metal oxide semiconductors, and emerging alternatives.

Piperonyl-Tethered Rhodanine Derivatives Potently Inhibit Chitinolytic Enzymes of .

Insect pest chitinases are potential target for developing new insect growth regulators. Piperine was found first to inhibit the insect chitinase (Chi-h) from (Asian corn borer) in this work, except for previously reported ChtI. Novel piperonyl-tethered rhodanine derivatives - were rationally designed with piperine as lead and synthesized by introducing a unique rhodanine moiety into the piperine scaffold based on the similar binding cavity of ChtI and Chi-h.

Cardiac troponin I autoantibody induces myocardial dysfunction by PTEN signaling activation.

Background: The objective of the current study was to study the molecular mechanism(s) underlying cardiac troponin I autoantibody (cTnIAAb) binding to cardiomyocyte and resultant myocardial damage/dysfunction.

Methods: cTnIAAb was purified from serum of 10 acute myocardial infarction (AMI) patients with left ventricular remodeling. Recombinant human cTnI was used to generate three mouse-derived monoclonal anti-cTnI antibodies (cTnImAb1, cTnImAb2, and cTnImAb3).

[Increased level of Th17 cells in peripheral blood correlates with the development of hepatocellular carcinoma].

Objective: To investigate the potential correlation between the level of Th17 cells in peripheral blood and the development of human hepatocellular carcinoma (HCC).

Methods: Th17 cells in the blood samples from 61 HCC patients and 38 healthy controls were assessed by flow cytometry (FCM). The mRNA expression levels of IL-17, IL-23p19 and RORc in peripheral blood mononuclear cells (PBMC) were detected by quantitative real-time PCR.
