Insights into plutonium in marine biota along the coast of China.

Radiation risk through seafood consumption is a big public concern under the discharge of nuclear contaminated water. Plutonium is an important radionuclide in view of radiation risk due to its high radiological and chemical toxicity, as well as consistent presence in the environment. The distribution and level of plutonium isotopes (Pu, Pu) in marine biota collected along the coast of China in 2022-2023 were investigated.

Efficient counter electrode for quantum dot sensitized solar cells using p-type PbS@reduced graphene oxide composite.

This study developed a novel PbS-rGO composite counter electrode to enhance the performance of quantum dot-sensitized solar cells (QDSSCs). The composite was synthesized a hydrothermal method by anchoring PbS nanocubes onto reduced graphene oxide (rGO) sheets. The effect of the mass ratio of rGO to PbS (0.

Vitamin B, B, and B Intakes and Risk of Gastric Cancer: Findings from a Case-Control Study.

Background/objectives: Gastric cancer is one of the leading malignancies worldwide. B vitamins play important roles in DNA synthesis and methylation because they are considered co-enzymes in one-carbon metabolism. There is inconclusive evidence regarding the associations between dietary vitamins B, B, and B with the risk of gastric cancer in different epidemiologic studies.

The Deformation of a Liquid Metal Droplet Under Continuous Acceleration in a Variable Cross-Section Groove.

This paper constructs a numerical simulation model for the deformation of droplets in a variable cross-section groove of a liquid droplet MEMS switch under different directions, amplitudes, frequencies, and waveforms of acceleration. The numerical simulation utilizes the level set method to monitor the deformation surface boundary of the metal droplets. The simulation outcomes manifest that when the negative impact acceleration on the -axis is 12.

A universal gene expression signature-based strategy for the high-throughput discovery of anti-inflammatory drugs.

Background: Traditional Chinese medicine (TCM) is a valuable resource for drug discovery and has demonstrated excellent efficacy in treating inflammatory diseases. This study aimed to develop a universal gene signature-based strategy for high-throughput discovery of anti-inflammatory drugs, especially Traditional Chinese medicine (TCM).

Methods: The disease gene signature of liposaccharide-stimulated THP-1 cells and drug gene signatures of 655 drug candidates were established via sequencing.
