Temporal and spatial variations of soil Se in China over the past half century and its influencing factors.

Soil serves as a significant reservoir of selenium (Se) and plays a crucial role for the entry of Se into the food chain. Therefore, it is of utmost importance to gain a deep understanding of the spatial and temporal variation of total soil Se content in China, as well as its influencing factors. This understanding is essential for the rational and efficient utilization of Se resources, the maintenance of ecological balance, and the preservation of human health in the future.

Current status of the development of dengue vaccines.

Dengue fever is caused by the mosquito-borne dengue virus (DENV), which is endemic in more than 100 countries. Annually, there are approximately 390 million dengue cases, with a small subset manifesting into severe illnesses, such as dengue haemorrhagic fever or dengue shock syndrome. Current treatment options for dengue infections remain supportive management due to the lack of an effective vaccine and clinically approved antiviral.

Multiomics analysis elucidated the role of inflammatory response and bile acid metabolism disturbance in electric shock-induced liver injury in mice.

Purpose: Organ damage caused by electric shock has attracted great attention. Some animal investigations and clinical cases have suggested that electric shock can induce liver injury. This study aimed to investigate the potential mechanism of liver injury induced by electric shock.

SKP1-CUL1-F-box: Key molecular targets affecting disease progression.

The correct synthesis and degradation of proteins are vital for numerous biological processes in the human body, with protein degradation primarily facilitated by the ubiquitin-proteasome system. The SKP1-CUL1-F-box (SCF) E3 ubiquitin ligase, a member of the Cullin-RING E3 ubiquitin ligase (CRL) family, plays a crucial role in mediating protein ubiquitination and subsequent 26S proteasome degradation during normal cellular metabolism. Notably, SCF is intricately linked to the pathogenesis of various diseases, including malignant tumors.

Allelic transcriptomic profiling identifies the role of PRD-like homeobox genes in human embryonic-cleavage-stage arrest.

Cleavage-stage arrest in human embryos substantially limits the success rate of infertility treatment, with maternal-to-zygotic transition (MZT) abnormalities being a potential contributor. However, the underlying mechanisms and regulators remain unclear. Here, by performing allelic transcriptome analysis on human preimplantation embryos, we accurately quantified MZT progression by allelic ratio and identified a fraction of 8-cell embryos, at the appropriate developmental time point and exhibiting normal morphology, were in transcriptionally arrested status.
