Development of a core outcome set and core measurement set for kangaroo mother care: a study protocol.

Background: Kangaroo mother care (KMC) is a care of preterm and low birthweight infants carried skin-to-skin contact with the mother's chest and breastfeeding when possible. KMC has been proven to reduce mortality and morbidity in these infants. However, research on KMC has been limited by significant variability and inconsistency in reported outcomes across studies.

The Arabidopsis heterotrimeric G protein α subunit binds to and inhibits the inward rectifying potassium channel KAT1.

In animal cells, Gα subunit of the heterotrimeric G proteins can bind to both the N-terminal and C-terminal domains of G-protein-activated inwardly rectifying K channels (GIRKs) to inhibit their activities. In Arabidopsis guard cells, the Gα subunit GPA1 mediates multiple stimuli-regulated stomatal movements via inhibiting guard cell inward-rectifying K (K) current, but it remains unclear whether GPA1 directly interacts with and inhibits the activities of K channels. Here, we found that GPA1 interacted with the transmembrane domain rather than the intracellular domain of the Shaker family K channel KAT1.

Biomimetic Total Synthesis of Clavicipitic Acid: A DDQ-Mediated Intramolecular Cross-Dehydrogenative Coupling Approach.

Clavicipitic acid, a communesin alkaloid precursor, has attracted significant attention due to its unique azepino[5,4,3-cd]indole framework. Herein, we report a novel biomimetic synthesis of clavicipitic acid diastereomers by utilizing a DDQ-mediated cross-dehydrogenative coupling (CDC) reaction. The synthesis involves Suzuki coupling for the prenylation of a 4-bromotryptophan derivative, followed by an intramolecular CDC reaction to construct the azepinoindole core.

Rationally designed MnO@ZnMnO/C core-shell hollow microspheres for aqueous zinc-ion batteries.

Manganese-based oxides are common cathode materials for aqueous zinc ion batteries (AZIBs) because of their great capacity and high working voltage. However, the sharp decline of capacity caused by the dissolution of manganese-based cathode materials and the low-rate performance restrict their development. To address these problems, unique core-shell structured MnO@ZnMnO/C hollow microspheres are reported as an ideal cathode material for AZIBs.

[Identification of important biodiversity areas by InVEST model considering opographic relief: A case study of Yunnan Province, China].

Accurately identifying important areas of biodiversity is one of the key issues in ecology and biodiversity research, as well as an important basis for the delineation of the red line for ecologi-cal protection and territorial spatial planning. With China's typical plateau mountainous area (Yunnan Province) as a research case, we used the net primary productivity (NPP) quantitative index method, InVEST model and InVEST model focusing on topographic relief to identify biodiversity important areas. The results showed that NPP quantitative index method was not suitable for the plateau mountainous areas with obvious vertical zonal development.
