Cationic lipopeptides self‐assemble into stable, cell‐like vesicles that merge peptide programmability with lipid self‐organization. These biocompatible compartments efficiently sequester and deliver nucleic acids, enabling high transfection efficiency with low‐toxicity in both HEK293T cells and mesenchymal stem cells (MSCs).

Staging concept for aging management: Definition, mechanism, and coping strategies
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Epac1 Alleviates Senescence in Auditory Hair Cells via the Ferroptosis
ABSTRACT Objectives The aim of this study was to investigate the changes in Epac1 and ferroptosis‐related proteins in aged mice and the House Ear Institute‐Organ of Corti 1 (HEI‐OC1) cells, with the goal of elucidating their potential role in age‐related hearing loss. Methods The expression of Epac1 in the cochlea of C57BL/6J mice was examined by using

AlignPCA‐2D: PCA‐reduced Euclidean vector alignment for 2D classification in cryo‐EM
We introduce AlignPCA‐2D, a PCA‐space Euclidean alignment method for rapid and interpretable 2D classification of cryo‐EM particle images. The approach preserves essential structural variability while greatly reducing computational cost, offering a lightweight alternative to existing large‐scale cryo‐EM classification pipelines.Cryogenic electron ...

ABSTRACT Objective Women with polycystic ovary syndrome (PCOS) exhibit a substantially increased risk of miscarriage, yet the underlying mechanisms remain inadequately understood. This study aimed to investigate whether specific gut microbial dysbiosis and metabolic disturbance are associated with and may potentially contribute to endometrial ...

The schematic diagram illustrates that the amphibian‐derived peptide OA‐AL14 protects against UVB‐induced skin photoaging through a dual mechanism: activating the Nrf2 pathway to counteract oxidative stress and modulating the AMPK/mTOR axis to induce protective autophagy. ABSTRACT Skin photoaging, primarily driven by ultraviolet B (UVB) radiation, is a

Rapid Human Skin Barrier Disruption by Sodium Dodecyl Sulfate and Associated Molecular Mechanisms
Short‐term exposure to SDS rapidly disrupts human skin barrier integrity within minutes, as detected by real‐time electrical impedance spectroscopy. SDS‐induced barrier dysfunction is driven by oxidative stress, leading to suppression of immune/barrier mediators and activation of stress, lipid remodeling, and epidermal differentiation pathways ...

ABSTRACT Background Cell therapy, particularly those utilizing mesenchymal stem/stromal cells (MSCs), is gaining traction as a therapeutic option for regenerative treatment in patients with limited therapeutic options. Although the safety of MSC‐based interventions is well established, uncertainties remain regarding how genetic abnormalities and ...

Targeting hexokinase 2 to induce breast cancer cell senescence
Background and Purpose Hexokinase 2 (HK2) is a key enzyme linked to high tumour cell proliferation. Its inhibitors such as 3‐bromopyruvic acid (3‐BP) induce cancer cell death, highlighting HK2 modulation as potential anti‐cancer treatment. However, standard chemotherapies often cause the emergence of senescent cancer cells, which goes along with cell ...
