Clinical and biochemical characteristics, and outcome in 33 patients with ceftriaxone-induced liver injury.

Purpose: To summarize the clinical and biochemical characteristics of patients with ceftriaxone-induced liver injury and guide the selection of safe medication.

Methods: Retrieved domestic and foreign databases from inception to October 2023, collected case data conforming to ceftriaxone-induced liver injury, and statistically analyzed the data.

Results: A total of 617 articles were retrieved, and 16 articles with 33 cases (10 children, 23 adults) were included.

Microbial community associated with ectomycorrhizal Russula symbiosis and dominated nature areas in southern China.

Russula griseocarnosa is one of the uncultivable important mycorrhizal edible fungi. Currently, there is a limited insight into the dynamic composition of the microbial communities associated with Russula. Here, the microbiota in the root and mycorrhizosphere from Russula-Fagaceae nature areas of Fujian province were identified by Illumina MiSeq high-throughput sequencing.

The cell cycle regulator 14-3-3σ opposes and reverses cancer metabolic reprogramming.

Extensive reprogramming of cellular energy metabolism is a hallmark of cancer. Despite its importance, the molecular mechanism controlling this tumour metabolic shift remains not fully understood. Here we show that 14-3-3σ regulates cancer metabolic reprogramming and protects cells from tumorigenic transformation.

DNA damage-induced protein 14-3-3 sigma inhibits protein kinase B/Akt activation and suppresses Akt-activated cancer.

14-3-3 sigma is induced by tumor suppressor protein p53 in response to DNA damage. p53 can directly transactivate the expression of 14-3-3 sigma to cause a G(2) cell cycle arrest when cell DNA is damaged. The expression of 14-3-3 sigma protein is down-regulated in various tumors, but its function has not been fully established.

14-3-3 sigma positively regulates p53 and suppresses tumor growth.

The 14-3-3 sigma (sigma) protein, a negative regulator of the cell cycle, is a human mammary epithelium-specific marker that is downregulated in transformed mammary carcinoma cells. It has also been identified as a p53-inducible gene product involved in cell cycle checkpoint control after DNA damage. Although 14-3-3 sigma is linked to p53-regulated cell cycle checkpoint control, detailed mechanisms of how cell cycle regulation occurs remain unclear.

Comparative study of enterovirus 71 infection of human cell lines.

The cell tropism of enterovirus 71 (Enteroviridae) in neuronal, glial and laryngeal cells. The 4643 strain, an enterovirus 71 isolate from a patient in Taiwan, was used to infect three human cell lines representing neuronal cells (SK-N-SH, neuroblastoma), glial cells (U373MG, glioblastoma), and laryngeal cells (HEp-2, larynx epidermoid carcinoma). Immunofluorescent staining and transmission electron microscopy (TEM) were used to detect mature enterovirus 71 4643 virions in these cell lines.
