Like animals, plants use asymmetric cell divisions to create pattern and diversity. Due to a rigid cell wall and lack of cell migrations, these asymmetric divisions incur the additional constraints of being locked into their initial orientations. How do plants specify and carry out asymmetric divisions? Intercellular communication has been suspected for some time and recent developments identify these signals as well as point to segregated determinants and proteins with PAR-like functions as parts of the answer.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) results in poor prognosis. Several risk factors for CSA-AKI have been reported, including preoperative creatinine level, cardiopulmonary bypass time, and perioperative blood pressure management. Only few studies have reported the effect of vascular stiffness on the incidence of CSA-AKI, and there are is no study reporting on endothelial function and its association with CSA-AKI.

Organics electrooxidation coupled hydrogen production has attracted increasing attention due to the low operation voltage. Nevertheless, the spontaneous production of hydrogen coupled with organics valorization remains challenging. Herein, we develop ultrathin Au/Pt twin nanowire (NW) catalysts for both electrochemical glucose oxidation and hydrogen evolution reaction towards a spontaneous hydrogen production system.

The widespread accumulation of androgenic steroid endocrine disruptors in water and food has garnered increasing attention due to their significant risks to ecosystems and human health. These steroids, which cannot be completely eliminated, highlight the urgent need for advanced detection technologies. In this study, we present a novel emulsion-induced interface-anisotropic assembly strategy to synthesize bowl-like mesoporous polydopamine (PDA) particles, which exhibit high sensitivity in surface-enhanced Raman scattering (SERS) detection.

As one of the most influential environmental factors, light fundamentally shapes plant physiology and growth traits. The hypocotyl is critical for the morphological establishment of the seedling, and its length displays remarkable plasticity upon perception of changes in the light conditions. Although remodeling of the primary cell walls is well-documented to play an important role in hypocotyl growth, how the hypocotyl elongation rate is swiftly repressed at the dark-to-light transition remains elusive.

We introduce a protocol for spatial proteomics using thin cryotome sections of mouse skeletal muscle tissue. We describe steps for preparing muscle sections and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analyses to generate spatial protein profiles along the longitudinal skeletal muscle axis. We detail procedures for scanning longitudinal protein profiles and replacing missing data using a sliding window approach.
