Synchronization‐Dissipation in the Cardiorespiratory System
Advanced Science, EarlyView.By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Developmental Biology, 2000 One way or another, all species possess the ability to regenerate damaged tissues. The degree of regeneration, however, varies considerably among tissues within a body and among species, with urodeles being the most spectacular. Such differences in regenerative capacity are indicative of specific mechanisms that control the different types of ...

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus
Advanced Science, EarlyView.This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Advanced Science, EarlyView.Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis
Advanced Science, EarlyView.Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.

Advanced Science, EarlyView.Ubiquilin (UBQLN), like many other human proteins, contains both well‐folded and disordered regions. Here, we show that intramolecular interactions between disordered regions and folded domains modulate between open and closed topologies of UBQLN proteins, altering their structure and function.

CellsUnlike conventional T cells, which express a highly diverse repertoire of dimeric αβ T-cell receptors (TCRs) restricted by classical, polymorphic MHC class I molecules (MHC-Ia), a distinct group of T cells—collectively termed “innate-like T (iT) cells ...

Richard Owen F.R.S. (1804–92) was a controversial and influential palaeontologist and anatomist. Owen studied medicine at the University of Edinburgh and at London's St Bartholomew's Hospital. He grew interested in anatomical research, and after qualifying he became assistant conservator in the museum of the Royal College of Surgeons, and then ...
