Unlabelled: Treatment of cancer patients with tyrosine kinase inhibitors (TKIs) often results in hypertension, but the underlying mechanism remains unclear. This study aimed to examine the role of mitochondrial morphology and function, particularly mitochondria-associated endoplasmic reticulum membranes (MAMs), in sunitinib-induced hypertension.
Methods: Both in vitro and in vivo experiments performed to assesse reactive oxygen species (ROS), nitric oxide (NO), endothelium-dependent vasorelaxation, systemic blood pressure, and mitochondrial function in human umbilical vein endothelial cells (HUVECs) and C57BL/6 mouse aortic endothelial cells, under vehicle or sunitinib treatment condition.
With the growing need for precise campus electricity management, understanding load patterns is crucial for improving energy efficiency and optimizing energy use. However, detailed electricity load data for campus buildings and their internal equipment is often lacking, hindering research. This paper introduces an energy consumption monitoring dataset from The Hong Kong University of Science and Technology (HKUST) campus in Hong Kong, comprising data from over 1400 meters across more than 20 buildings and collected over two and a half years.

The reaction of 3 with CO yielded a trimeric carbonate complex [{LGa(CO)}{μ-K(THF)}] (4) and a dinuclear oxo-carbonate complex [K(THF)][LGa(μ-CO)(μ-O)GaL] (5) in one pot through reductive disproportionation of CO. For CS, two ethenetetrathiolate gallium complexes, [M(Solv)][LGa(μ-CS)GaL] (M=Na, Solv=THF, 6; M=K, Solv=DME, 7), were obtained via reductive coupling of CS.

This group-level organizational change fairness is crucial for enhancing proactive motivation states and fostering positive change-oriented organizational citizenship behavior (OCB). Rooted in the proactive motivation model, this study establishes a comprehensive multilevel framework to investigate the influence of group-level organizational change fairness on employees' change-oriented OCB.

Most existing solid waste management systems, are designed with a top-down approach, covering multiple industries and sectors. However, these systems often fail to effectively manage potentially viral solid waste in household waste, which impedes effective solid waste management during public health emergencies and increases the risk of viral outbreaks.

In the reaction of with benzophenone or 4,4'-di--butylbenzophenone, a multielectron transfer process was observed to give bimetallic (Zn/K) complexes with both ketyl radical fragments and C-C coupled pinacolate moieties (products and ). In contrast, treating with 9-fluorenone only afforded pinacolate complex .

This paper introduces a smart predictive solution: the Smart Internal Drainage Roof (SIDR) system, which leverages forecasted data to enhance the mitigation of pluvial floods in Central Business District (CBD) areas. Unlike traditional approaches, SIDRs utilize a synergistic combination of Rule-based Control (RBC) and Model Predictive Control (MPC) algorithms, tailored to optimize the operational efficiency of both grey and green roofs.

Heteroleptic, bimetallic (Mg/K) cyclopentadienyl complexes (2-4) were synthesized by the reaction of the Mg-Mg-bonded compound [K(THF)][LMg-MgL] (1, L = [(2,6-iPrCH)NC(CH)]) with cyclopentadiene derivatives, 6,6-dimethylfulvene, 6-(dimethylamino)fulvene, or 1,2,3,4-tetramethyl-1,3-cyclopentadiene. The reactions proceed through diverse pathways, including hydrogen abstraction, C-C coupling, and dehydrogenation, depending on the property of the polyene substrate, thus providing an access to alkali/alkaline earth metal cyclopentadienyl complexes.

Further investigating mechanisms underlying NP is therefore of great importance for discovering more promising therapeutic targets. In the current study, we employed high-throughput RNA sequencing to explore transcriptome profiles of mRNAs and microRNAs in the dorsal root ganglia (DRG) following chronic constriction injury (CCI) and also integrated published datasets for comprehensive analysis.

In this study, the variations of source-specific light absorption (b) and direct radiative effect (DRE) were obtained during and after the lockdown period by using the artificial neural network (ANN) and source apportionment environmental receptor model. The results showed that the b decreased for all sources during the two periods.

Air pollution continues to be a serious problem in Xi'an. A heavy pollution process and formation mechanism were investigated in Xi'an in January 2019 using multi-source methods (such as material balance and sulfur/nitrogen oxidation rate (SOR/NOR)). The multi-source data included the concentrations of PM, PM, SO, NO, CO, and O; the chemical components of PM; the meteorological records of ground and vertical observations; the atmospheric reanalysis data.

In the reaction of 1 with Me SiNCNSiMe , one of the easily leaving trimethylsilyl groups is lost to yield the Me SiNCN moiety that either bridges two Mg centers (2) or terminally coordinated (3). In contrast, with the similarly bulky tBuNCNtBu, the carbodiimide inserts into Mg-Mg bond with accompanying C-H activation of a ligand or solvent (products 4 and 5).
