Controlled reconstruction of metal-organic frameworks coordination environment tuning as oxygen evolution electrocatalysts.
Dalton Trans
January 2025
Faculty of Metallurgical and Energy Engineering, Kunming University of Science and Technology, Kunming, China.
During the oxygen evolution reaction (OER), metal-organic framework (MOF) catalysts undergo structural reorganization, a phenomenon that is still not fully comprehended. Additionally, designing MOFs that undergo structural reconstruction to produce highly active OER catalysts continues to pose significant challenges. Herein, a bimetallic MOF (CoNi-MOF) with carboxylate oxygen and pyridine nitrogen coordination has been synthesized and its reconstruction behavior has been analyzed.

Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).
Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.
Variation of physical wood properties and effect of dasometric variables in trees growing in plantation.
Heliyon
January 2025
Escuela de Ingeniería Forestal, Instituto Tecnológico de Costa Rica, Apartado, 159-7050, Cartago, Costa Rica.
Physical properties were studied in commercial plantation of balsa established in Costa Rica. Among other variables studied, physical properties varied mainly for tree age, spacing, stand density, diameter, and height of trees, which we named dasometric conditions. The aim of this study was (i) to determine the variation of specific gravity (SG), air-dry density (AD), green density (GD), and green moisture content (GMC), (ii) to know the site effect and dasometric conditions on these properties, and (iii) to establish the relationship between the four physical properties.

However, injecting sclerosing agents into blood vessels is technically challenging and often ineffective. Gel-immersion EIS (GI-EIS) may facilitate easier intravascular sclerosing agent injection by dilating the varices and enhancing scope stability by maintaining low intra-gastrointestinal pressure.

Middle East J Dig Dis

Department of Colorectal Surgery, Colorectal Research Center, Imam Khomeini Hospital Complex, Tehran University of Medical Sciences, Tehran, Iran.
Background: Low anterior resection (LAR) is the gold standard for curative cancer treatment in the middle and upper rectum. In radically operated patients, the local recurrence rates with total mesorectal excision (TME) after 5 and 10 years was<10%, with 80% in 5 years survival. Anastomotic leakage (AL) affects 4%-20% of patients who underwent LAR.
