Background: Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, with the worst prognosis among all subtypes. The impact of distinct cell subpopulations within the tumor microenvironment (TME) on TNBC patient prognosis has yet to be clarified.

Methods: Utilizing single-cell RNA sequencing (scRNA-seq) integrated with bulk RNA sequencing (bulk RNA-seq), we applied Cox regression models to compute hazard ratios, and cross-validated prognostic scoring using a GLMNET-based Cox model.

Objective: In this study, we examined the genetic, medical, and molecular traits of two Han Chinese families with the tRNA G5783A mutation to investigate the relationship between mitochondrial DNA (mtDNA) mutations and major depressive disorder (MDD).

Methods: Clinical data and comprehensive mitochondrial genomes were collected from the two families. Variants were assessed for evolutionary conservation, allelic frequencies, and their structural and functional impacts.

Nanohydroxyapatite (nHA) is distinguished by its exceptional biocompatibility, bioactivity and biodegradability, qualities attributed to its similarity to the mineral component of human bone. This review discusses the synthesis techniques of nHA, highlighting how these methods shape its physicochemical attributes and, in turn, its utility in biomedical applications. The versatility of nHA is further enhanced by doping with biologically significant ions like magnesium or zinc, which can improve its bioactivity and confer therapeutic properties.

Mucormycosis is considered a rare but highly lethal fungal infection, often occurring in patients with poorly controlled diabetes or immunosuppression. Pulmonary mucormycosis progresses rapidly and is often associated with pulmonary infarction and hemoptysis. In this case report, we presented a young, immunocompetent female patient with newly diagnosed diabetes who was diagnosed early with infection through metagenomic next-generation sequencing.
