Abstract Plant innate immune response to pathogen infection includes an elegant signaling pathway leading reactive oxygen species generation and resulting hypersensitive (HR); localized programmed cell death in tissue surrounding the initial site limits spread. A veritable symphony of cytosolic molecules (including Ca2+, nitric oxide [NO], cyclic nucleotides, calmodulin) have been suggested as early components HR signaling. However, specific interactions among these secondary messengers...

Mutations in the kinase WNK4 cause pseudohypoaldosteronism type II (PHAII), a syndrome featuring hypertension and high serum K(+) levels (hyperkalemia). has distinct functional states that regulate balance between renal salt reabsorption secretion by modulating activities of transporters channels, including Na-Cl cotransporter NCC channel ROMK. WNK4's functions could enable differential responses to intravascular volume depletion (hypovolemia) hyperkalemia. Because hypovolemia is uniquely...

Humidity sensors are commonly based on the resistance change of metal oxide semiconductors, which show high sensitivity in low humidity but humidity. In this work, we design a novel sensor airflow-induced triboelectric nanogenerator (ATNG) that can serve as self-powered to detect (especially humidity) and airflow rate. The output current or voltage is investigated under different (20–100% relative at fixed rate rates (15–25 L/min) working principle ATNG-based illustrated. We find both...

The steroid hormone aldosterone is secreted both in the setting of intravascular volume depletion and hyperkalemia, raising question how kidney maximizes NaCl reabsorption former state while maximizing K(+) secretion latter. Mutations WNK4 cause pseudohypoaldosteronism type II (PHAII), a disease featuring increased renal impaired secretion. PHAII-mutant achieves these effects by increasing activity Na-Cl cotransporter (NCC) Na(+) channel ENaC concurrently inhibiting outer medullary (ROMK)....

Harvesting airflow energy and light from the ambient environment to build a self-powered system is attractive challenging work. In this article, an airflow-induced triboelectric nanogenerator (ATNG) has been fabricated that converts wind alternating electricity. The mechanism of ATNG also illustrated. performance ATNGs with different sizes was studied, which we discovered (size: 1 cm × 3 cm, electrode gap: 1.5 mm) could easily collect gentle (5.3 m s−1). Due relatively high electricity...

Photocatalytic degradation of organic contaminants is an important application area in solar energy utilization. To improve material photocatalytic properties, understanding their mechanism indispensable. Here, the performance ZnWO4 nanocrystals was systematicly investigated by photodegradation tetraethylated rhodamine (RhB) under simulated sunlight irradiation, including influence morphology, AgO/ZnWO4 heterojunction and comparison with CoWO4 nanowires. The results show that activity higher...

The serine–threonine kinase WNK3 modulates Cl − transport into and out of cells through its regulation SLC12A cation–Cl cotransporters, implicating it as (one of) the long‐sought /volume‐sensitive kinase(s). Integrators in homeostatic systems regulate structurally diverse but functionally coupled elements. For example, related WNK4 regulates Na + –Cl cotransporter (NCC), paracellular flux, K channel ROMK1 (Kir1.1) to maintain renal NaCl homeostasis; mutations PRKWNK4 , encoding WNK4, cause a...
