Article Abstract
To elucidate aging-associated cellular population dynamics, we present PanSci, a single-cell transcriptome atlas profiling >20 million cells from 623 mouse tissues across different life stages, sexes, and genotypes. This comprehensive dataset reveals >3000 different cellular states and >200 aging-associated cell populations. Our panoramic analysis uncovered organ-, lineage-, and sex-specific shifts in cellular dynamics during life-span progression. Moreover, we identify both systematic and organ-specific alterations in immune cell populations associated with aging. We further explored the regulatory roles of the immune system on aging and pinpointed specific age-related cell population expansions that are lymphocyte dependent. Our "cell-omics" strategy enhances comprehension of cellular aging and lays the groundwork for exploring the complex cellular regulatory networks in aging and aging-associated diseases.

Evaluation of ambulatory use of daratumumab hyaluronidase injection.

IntroductionDaratumumab is a therapeutic cornerstone of the management of multiple myeloma, exerting its anti-myeloma activity through targeting of the cell surface glycoprotein CD38 on plasma cells. While originally given intravenously, the subcutaneous formulation, daratumumab hyaluronidase injection (Dara SC), has been associated with non-inferior efficacy and lower infusion-related reaction rates (IRRs) in the treatment of multiple myeloma and light chain amyloidosis. A noted benefit of Dara SC is a short administration time; however, the optimal observation time post injection to ensure patient safety is unclear from the drug labeling.

Background: Lung cancer (LC) is the leading cause of cancer-related deaths globally. Genetic variants in mismatch repair (MMR) genes, such as MutS homolog 2 (MSH2), MutS homolog 6 (MSH6) and MutL homolog 1 (MLH1), may influence individual susceptibility and clinical outcomes in LC.
Objective: This study investigated the associations of genetic polymorphisms in MSH2, MSH6, and MLH1 with susceptibility and survival outcomes in lung cancer patients in the Guangxi Zhuang population.

The COVID-19 pandemic, caused by the continuously evolving SARS-CoV-2 virus, has presented persistent global health challenges. As novel variants emerge, many with enhanced transmissibility and immune evasion capabilities, concerns have intensified regarding the efficacy of existing vaccines and therapeutics. This review provides a comprehensive overview of the current landscape of COVID-19 vaccination, including the development and performance of monovalent and bivalent boosters, and examines their effectiveness against newly emerging variants of interest (VOIs) and variants under monitoring (VUMs), such as JN.

Regenerative cardiology has emerged as a novel strategy to improve cardiac healing following ischemic injury. While stem-cell-mediated cardiac regeneration has garnered much attention as a promising strategy, its value remains debated owing to the lack of ideal stem cell source candidates. Resident/endogenous cardiac-derived stromal cells (CSCs) exhibit superior therapeutic potential due to their innate abilities to differentiate into cardiac cells, especially cardiomyocytes (CM).

Sodium orthovanadate (vanadate), a potent inhibitor of p53, has been shown in earlier work to alleviate total-body irradiation (TBI)-induced hematopoietic syndrome. However, as p53 plays a crucial role in normal spermatogenesis, its suppression may raise concerns about potential adverse effects on male reproductive function. In this study, we investigated whether vanadate exacerbates impairment of male fertility when administered for hematopoietic protection under TBI conditions.
