Ancient engineers: The role of plateau pika in shaping ecological uniqueness and guiding plant diversity conservation in alpine grasslands.

Small burrowing herbivores play a crucial role in maintaining structure and function of grassland ecosystems. To date, our understanding of whether practicing ecological uniqueness can enhance plant diversity conservation under small herbivore disturbances remains limited. Here, we investigate the ecological uniqueness of plant communities, which include habitats disturbed and undisturbed by plateau pikas.

Bitter acids from Humulus lupulus L. alleviate D-galactose induced osteoblastic senescence and bone loss via regulating AKT/mTOR-mediated autophagy.

Bitter acids (BA) are main component of Humulus lupulus L. (hops). They are known for beer brewing and have various biological and pharmacological properties, especially the bone-protective effect confirmed by our previous in vivo study.

Measurement of CP Violation Observables in D^{+}→K^{-}K^{+}π^{+} Decays.

A search for violation of the charge-parity (CP) symmetry in the D^{+}→K^{-}K^{+}π^{+} decay is presented, with proton-proton collision data corresponding to an integrated luminosity of 5.4  fb^{-1}, collected at a center-of-mass energy of 13 TeV with the LHCb detector. A novel model-independent technique is used to compare the D^{+} and D^{-} phase-space distributions, with instrumental asymmetries subtracted using the D_{s}^{+}→K^{-}K^{+}π^{+} decay as a control channel.

Glutathione-Responsive Metal-Organic-Framework-Derived MnO/(A/R)TiO Nanoparticles for Enhanced Synergistic Sonodynamic/Chemodynamic/Immunotherapy.

Despite the potential of sonodynamic therapy (SDT) in treating malignant tumors, the lack of effective sonosensitizers has limited its clinical implementation. In this study, we explored the relationship between the heteroatom doping concentration in metal-organic frameworks and interface formation after pyrolysis by regulating the addition of manganese sources and successfully derived Z-scheme heterojunctions MnO/(A/R)TiO (MTO) in situ from MIL-125-NH (Ti/Mn). The electron transfer pathway introduced by interfacial contact promoted carrier separation and greatly preserved the effective redox components, significantly influencing the performance of reactive oxygen species generation.

Basic Science and Pathogenesis.

Background: Accumulation of the amyloid-β (Aβ) peptide into amyloid plaque is one of the key pathological markers of Alzheimer's disease (AD). Apolipoprotein E (APOE) is known to modify AD risk and has been reported to influence Aβ accumulation in the brain in an isoform-dependent manner. ApoE can be produced by various cell types in the brain, with astrocytes being the main producer.
