Bi-MOF Modulating MnO Deposition Enables Ultra-Stable Cathode-Free Aqueous Zinc-Ion Batteries.

The Mn-based materials are considered as the most promising cathodes for zinc-ion batteries (ZIBs) due to their inherent advantages of safety, sustainability and high energy density, however suffer from poor cyclability caused by gradual Mn dissolution and irreversible structural transformation. The mainstream solution is pre-adding Mn into the electrolyte, nevertheless faces the challenge of irreversible Mn consumption results from the MnO electrodeposition reaction (Mn  → MnO ). This work proposes a "MOFs as the electrodeposition surface" strategy, rather than blocking it.

Biomarkers in Cardiorenal Syndromes.

There is a consensus that cardiorenal syndromes (CRS) are defined as the disorders of heart and kidney where acute or chronic dysfunction in one organ may induce acute or chronic dysfunction in another. Patients with CRS have increased hospitalization and mortality rates, and thus their identification is of great implication. Biomarkers are not only predictive in heart failure or renal diseases, but also useful in identifying cardiac dysfunction in renal diseases and renal injury in heart failure.

Poor sleep is responsible for the impaired nocturnal blood pressure dipping in elderly hypertensive: A cross-sectional study of elderly.

Objective: This study was aimed to assess whether sleep disorder was associated with an increased risk of less nocturnal blood pressure (BP) dipping in elderly patients with hypertension.

Methods: Cases were 1006 patients, aged >60 years, who were admitted to hospital with diagnosed hypertension during 2016-2017, and were divided into three groups with the systolic nocturnal BP dipping of 10%, and 0% as the cut-off value. The patients' sleep was evaluated by Pittsburgh sleep quality index (PSQI).
