Physiological and anatomical determinants of placental drug transfer

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Fetal exposure to pharmaceuticals and their subsequent clearance back to the maternal circulation are governed by placental transfer. Passive diffusion down a maternal‐to‐fetal concentration gradient is the primary route of fetal drug exposure, with specific compounds undergoing transporter‐mediated transfer.

Brain Aromatase in the guppy, Poecilia reticulata [Elektronisk resurs] : Distribution, control and role in behaviour

open access: yes, 2009
Oestrogens are produced by aromatisation of androgens by the aromatase enzyme. In the vertebrate brain this synthesis has vital functions in nerve protection, cell proliferation and nerve development during injury respectively brain development.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Molecular Control of Neural Stem Cell Quiescence in the Adult Zebrafish Telencephalon: Established Mechanisms and an Integrative Hypothesis

open access: yesGlia, Volume 74, Issue 12, December 2026.
Adult zebrafish radial glia quiescence is controlled by at least four mechanisms: Notch3, BMP‐Id1, Nr2f1b and Midkine‐a. We propose these act as partially redundant inputs, biased along the antero‐posterior axis that set quiescence depth. ABSTRACT The zebrafish telencephalon is an excellent model for adult neurogenesis under physiological and ...

Association Between BMI and the Efficacy and Safety of CDK4/6 Inhibitors in HR+/HER2− Advanced Breast Cancer: A Multicenter Retrospective Propensity Score Matched Cohort Study (CAMELIA)

open access: yesMedComm – Oncology, Volume 5, Issue 4, December 2026.
This multicenter real‐world study showed that higher BMI (≥ 25 kg/m2) was independently associated with improved PFS in patients with HR+/HER2− advanced breast cancer receiving CDK4/6 inhibitors. Safety outcomes were comparable between BMI groups, and the findings were consistent across alternative BMI thresholds, suggesting the potential prognostic ...

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, Volume 20, Issue 10, Page 2424-2448, October 2026.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Risk of Retinopathy Associated with Long‐Term Use of Hydroxychloroquine in Patients with Rheumatic Diseases: A Systematic Review and Meta‐Analysis

open access: yesArthritis Care &Research, Volume 78, Issue 10, Page 1532-1543, October 2026.
Objective We aimed to estimate the prevalence and cumulative incidence of hydroxychloroquine retinopathy (HCQ‐R) and its risk factors among patients receiving long‐term HCQ with rheumatic diseases through a systematic review and meta‐analysis of observational studies that used spectral‐domain optical coherence tomography (SD‐OCT) for screening ...

Spatially Organized Human Ovarian Spheroids Instruct Endometrial Morphogenesis

open access: yesAdvanced Science, Volume 13, Issue 55, 5 October 2026.
A spatially organized human follicle‐like spheroid (SPHEGaT) composed of granulosa cells (GCs) and stromal‐derived theca‐like cells (TLCs) establishes sustained steroidogenesis in vitro. When co‐cultured with human endometrial organoids (EMOs), estradiol (E2) and progesterone (P4) exchange induces secretory/progesterone‐responsive differentiation ...
