Background: Herpes zoster is a potential risk factor for dementia. The effectiveness of the recombinant zoster vaccine for preventing dementia is uncertain.
Methods: This retrospective cohort study used de-identified claims data from the Optum Labs Data Warehouse database from January 1, 2017, to December 31, 2022, to determine whether the recombinant zoster vaccine is associated with a reduced risk of dementia.
Background: Inhibitors targeting cyclin-dependent kinases 4 and 6 (CDK4/6), crucial for cell cycle regulation, have shown promise in early-stage studies for treating central nervous system (CNS) tumors. However, challenges such as limited CNS penetration, optimal treatment duration, and systemic side effects have impeded their clinical translation for pediatric brain tumors (PBTs).
Methods: We evaluated the potency of CDK4/6 inhibitors across various PBTs cell lines, focusing particularly on palbociclib against atypical teratoid rhabdoid tumor (ATRT) with cell viability assays and gene expression analysis.
The PIM kinase family, consisting of PIM1, PIM2, and PIM3, is a group of serine/threonine protein kinases crucial for cellular growth, immunoregulation, and oncogenesis. PIM1 kinase is often overexpressed in solid and hematopoietic malignancies, promoting cell survival, proliferation, migration, and senescence by activating key genes. In vitro and in vivo studies have established the oncogenic potential of PIM1 kinases.

- The study examines lead (Pb) pollution in the Western Indian Ocean, using a 24-year coral record from Lakshadweep to understand historical and current contamination levels and their effects on the environment.
- Results show that lead concentrations in surface seawater nearly doubled from 1990 to 2013, mainly due to anthropogenic sources like aerosol pollution from land.
- The findings reveal significant differences in lead isotope distributions between the western and eastern Indian Ocean, indicating a substantial impact of human activity, which underscores the need for tailored environmental management in the region.
