Hsa_circ_0026782 Acts as a “Molecular Break” of CREB1‐Mediated Transcription by Promoting Its Phosphorylation at Ser142 That Prevents Keloid Progression

open access: yesAdvanced Science, EarlyView.
Model for the role of hsa_circ_0026782/p‐CREB1 (Ser142) played in keloid. Hsa_circ_0026782 is derived from back‐splicing of ITGA7 exon 4. When hsa_circ_0026782 binds to CREB1, the exposure of the bZIP domain and dimerization of CREB1 are promoted (upper left).

Comparative Single‐Cell Transcriptomic Landscape Reveals the Regulatory Mechanisms of Lactation during Selective Breeding in Asian Water Buffalo

open access: yesAdvanced Science, EarlyView.
In this study, a comprehensive single‐cell transcriptome atlas of river and swamp buffalo, encompassing 12 tissues and 397,011 cells, is constructed. Differential expression analyses identify metabolic and secretory tissues and cell types that mediate the divergence of milk production.

Optimal Chirality Enhances Long‐Range Fluctuation‐Induced Interactions in Active Fluids

open access: yesAdvanced Science, EarlyView.
Chiral active particles move along curved trajectories arising from the interplay of propulsion and self‐rotation. How chirality influences fluctuation‐induced forces in active matter systems remains unclear. It is shown that particle shape dictates this effect: chirality suppresses forces for circular particles but can enhance them for elongated ones,

Validation of the polysemen admixture on viability and acrosomal morphology of boar spermatozoa [PDF]

open access: yes, 2007
Semen were collected using artificial vagina (AV), from 5 large white boars aged 2-2.5 years twice a week for 16 weeks in each of the two seasons, early rainy (ER) and late rainy (LR) seasons, to determine the effects of multiple semen pool admixture on ...

Modulation of Aging Diseases via RAGE Targets: A Dietary Intervention Review

open access: yesAdvanced Science, EarlyView.
This paper analyzes RAGE ligand‐binding mechanisms and signaling, proposing intervention strategies targeting these interactions. It emphasizes dietary polyphenols, polysaccharides, and terpenoids delivered via functional foods for anti‐aging. These compounds offer long‐term, safe intervention through dietary supplementation, providing dual nutritional
