The Fertility Effects of Reducing Implicit Childcare Subsidies: The Case of School Schedules

open access: yesJournal of Policy Analysis and Management, Volume 45, Issue 4, Fall 2026.
ABSTRACT Despite governments’ efforts to raise fertility through family‐support policies, birth rates continue to decline in high‐ and middle‐income countries. Some policies designed for other purposes, however, may function as implicit childcare subsidies.

Chemotherapeutic Potential of Fluorouracil‐Platinum (IV) Prodrugs Against Cisplatin‐Resistant Colorectal Cancer Cells

open access: yesChemistry – A European Journal, Volume 32, Issue 30, 13 August 2026.
ABSTRACT Fluorouracil‐platinum(IV) prodrugs represent a novel class of multimechanistic chemotherapeutics with enhanced anticancer potential. The prodrugs PtIVP‐5FUMeOBut and PtIV56‐5FUMeOBut were actualized by derivatising the clinical drug 5‐fluorouracil (5FU) and coordinating it to platinum(IV) complexes, leveraging the established cytotoxicity of ...

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

open access: yesFEBS Open Bio, Volume 16, Issue 8, Page 1501-1508, August 2026.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Brown Adipocyte Sheets Alleviate Myocardial Ischemia–Reperfusion Injury Through NRG4–ErbB4–Dependent Ferroptosis Inhibition

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
Brown adipocyte sheets are engineered to protect the heart against myocardial ischemia–reperfusion injury by restraining ferroptosis. Upon transplantation onto the cardiac surface, they improve cardiac function, limit infarction and fibrosis, and enhance angiogenesis.

A Plug‐and‐Play Platform for Customizing Multivalent Degraders and Degrader‐Drug Conjugates

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
Membrane proteins remain challenging targets for conventional TPD approaches. Here, the authors develop UPTAB, a modular platform leveraging ultrahigh‐affinity orthogonal Im/CL protein pairs for lysosomal degradation of membrane proteins. Mono‐targeted (Type‐I), dual‐targeted (Type‐II), and tri‐targeted (Type‐III) UPTABs enable simultaneous degradation

Expression and Role of the RNA‐Binding Protein, ZFP36L1, in Mouse T Follicular Helper Cell Differentiation and Function

open access: yesEuropean Journal of Immunology, Volume 56, Issue 8, August 2026.
T follicular helper (Tfh) cells support germinal center (GC) B cells, generating long‐lived antibody‐secreting and memory B cells. RNA‐binding proteins likely fine‐tune Tfh function, but selective deletion of ZFP36L1 from Tfh cells alters neither their differentiation nor GC responses. This suggests further redundancy within the ZFP36 family.

Lipid‐based Nano‐delivery systems as a promising strategy for the treatment of epilepsy: Current status and challenges

open access: yesEpilepsia Open, Volume 11, Issue 4, Page 1095-1110, August 2026.
Abstract Objective Epilepsy is a prevalent chronic neurological disorder characterized by abnormal neuronal electrical activity. The primary treatment modality for individuals with epilepsy (PWE) is antiseizure medication (ASM). The multiple potential factors contributing to treatment resistance in epilepsy may be attributed to the inability of ASMs to
