A Hydrolytically Stable Cu(II)-Based Metal-Organic Framework with Easily Accessible Ligands for Water Harvesting.

Water scarcity is a critical issue in desert and arid regions, and atmospheric water harvesting is a potential solution. The challenge is lacking ideal adsorbents that can efficiently capture water from low-humidity air and be regenerated readily. Herein, we report a hydrolytically stable metal-organic framework (MOF), [Cu(AD)(SA)] (Cu-AD-SA), with excellent performance in water harvesting.

[Expression of follistatin, activin A and BMP-4 in rats with hypoxic-ischemic brain damage].

Objective: To investigate the expression and significance of follistatin, activin A and bone morphogenetic protein-4 (BMP-4) in normal brain tissues of rats and the brain tissues with hypoxic and ischemicgin.

Methods: Sixty conception SD rats were divided into normal and model group (with 30 for each). According to the development of fetal rats in each group, they were randomly divided into six subgroups (embryonic stage 8.
