In the title compound, C(9)H(10)NO(4) (+)·Cl(-)·2H(2)O, both the cation and the anion have crystallographic twofold rotation symmetry; in the former, one N and one C atom lie on the rotation axis. In the crystal structure, the ions and water mol-ecules are linked via O-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds into layers parallel to (101).

Heart remodelling affects ECG in rat DOCA/salt model.

Physiol Res

December 2024

Department of Physiology, Faculty of Medicine, Masaryk University, Brno, Czech Republic.

Myocardial remodelling involves structural and functional changes in the heart, potentially leading to heart failure. The deoxycorticosterone acetate (DOCA)/salt model is a widely used experimental approach to study hypertension-induced cardiac remodelling. It allows to investigate the mechanisms underlying myocardial fibrosis and hypertrophy, which are key contributors to impaired cardiac function.

Morphology regulation and element doping are effective means to improving the photocatalytic performance of graphite-phase carbon nitride (g-CN). In this article, using melamine and zinc chloride as raw materials, a novel kind of Zn/Cl-doped hollow microtubular g-CN (Zn-HT-CN) by a hydrothermal method was developed. The structure and morphology of Zn-HT-CN and reference samples were characterized by X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), etc.

The structural and electronic changes are investigated in a 3D hybrid perovskite, methylhydrazinium lead chloride (MHyPbCl) from a host/guest perspective as it transitions from a highly polar to less polar phase upon cooling, using first-principles calculations. The two phases vary structurally in the guest (MHy) orientation and the two differently distorted host (lead halide) layers. These findings highlight the critical role of guest reorientation in reducing host distortion at high temperatures, making the former the primary order parameter for the transition, a notable contrast to the case of other hybrid perovskites.

Virucidal activity of olanexidine gluconate against SARS-CoV-2.

Access Microbiol

January 2025

Department of Clinical Microbiology, School of Pharmacy, Tokyo University of Pharmacy and Life Sciences, 1432-1 Horinouchi, Hachioji, Tokyo 192-0392, Japan.

Antiseptics have been used for infection control against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Ethanol (EtOH) was found to be effective against SARS-CoV-2, while chlorhexidine gluconate (CHG) was less effective. Therefore, virucidal activity may differ between different classes of antiseptic agents.

This study aimed to conduct a bibliometric analysis of the 100 most cited articles on experimental cardiac arrest models in rats, identifying key contributors, publication trends, research themes, and collaboration networks. A comprehensive literature search was performed on the Web of Science (WoS) database on June 11, 2024, using keywords related to cardiac arrest and rat models. The top 100 most cited articles were analyzed using the Biblioshiny web application from the Bibliometrix R package (version 4.
