SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

open access: yesAdvanced Science, EarlyView.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

The Function of Themis2 in B Cells [PDF]

open access: yes, 2015
Thymocyte-expressed molecule involved in selection 2 (Themis2) is the second member of the Themis family. Recently, the first member of the Themis family, Themis, has been reported to be part of the TCR signalling cascade and its deletion severely ...

An Innervated Human Skin Equivalent that Electrically Encodes Mechanical and Thermal Stimuli

open access: yesAdvanced Science, EarlyView.
An innervated human skin equivalent is integrated with high‐density microelectrode arrays to reveal how engineered free nerve ending–like structures translate touch and temperature into electrical codes. Mechanical indentation and thermal stimulation engage the engineered somatosensory circuitry and evoke distinct firing and waveform signatures ...

The architecture of neoplastic follicles in follicular lymphoma; analysis of the relationship between the tumor and follicular helper T-cells

open access: yes, 2019
CD4+ T-follicular helper cells are essential for the survival, proliferation, and differentiation of germinal center B-cells and have been implicated in the pathogenesis of follicular lymphoma.

Dual‐Targeting Biomimetic Nanozymes Loaded Microneedle Patch Promotes Scarless Wound Healing Through Anti‐Inflammatory and Anti‐Fibrotic Effects

open access: yesAdvanced Science, EarlyView.
This study developed a dual‐targeting biomimetic nanozyme hybrid system (Cu‐CeO2@ABs‐FTP) and integrated it with HAMA hydrogel to fabricate a microneedle patch (CAF@MN). The patch promotes fibroblast‐mediated wound repair, targets macrophages to induce M2 polarization, and targets myofibroblasts to exert anti‐fibrotic effects, thereby enabling rapid ...

Electronics‐Free Visual Monitoring of Dry Eye Disease‐Related Tear Biomarkers Using Smart Scleral Lenses

open access: yesAdvanced Science, EarlyView.
An electronics‐free smart scleral lens passively monitors dry eye disease‐related tear biomarkers through colorimetric sensing of chloride, pH, and ocular surface temperature. Smartphone‐assisted image analysis enables quantitative interpretation, providing a simple, non‐invasive strategy for ocular health monitoring without integrated electronics ...

Diagnostic Challenges in Nodal T-Follicular Helper (TFH) Cell Lymphoma

open access: yesBioMed
Nodal T-follicular helper cell lymphomas comprise a biologically similar but morphologically diverse family of T-cell neoplasms, including angioimmunoblastic T-cell lymphoma, nodal T-follicular helper cell lymphoma, follicular-type, and nodal TFH ...

Integrated O2 and H2 Gas Therapy via Microneedle‐Assisted Photocatalytic Water Splitting for Accelerating Diabetic Full‐Thickness Skin Wound Healing

open access: yesAdvanced Science, EarlyView.
A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via
