Factor XI as a new target for prevention of thromboembolism in cardiovascular disease: a meta-analysis of randomized controlled trials.

Anticoagulant therapy is a mainstay in the management of patients with cardiovascular disease. The use of conventional anticoagulants carries potential side effects, mainly bleeding. Drugs targeting Factor XI (FXI) have been investigated in randomized controlled trials as a new option with more favorable outcomes.

Design, Synthesis, Computational Investigations, and Antitumor Evaluation of -Rhodanine Glycosides Derivatives as Potent DNA Intercalation and Topo II Inhibition against Cancer Cells.

Nitrogen and sulfur glycosylation was carried out via the reaction of rhodanine () with α-acetobromoglucose under basic conditions. Deacetylation of the protected nitrogen nucleoside was performed with CHONa in CHOH without cleavage of the rhodanine ring to afford the deprotected nitrogen nucleoside . Further, deacetylation of the protected sulfur nucleoside was performed with CHONa in CHOH with the cleavage of the rhodanine ring to give the hydrolysis product .

Synthesis, DFT, molecular dynamics, and Monte Carlo simulation of a novel thiourea derivative with extraordinary inhibitive properties for mild steel in 0.5 M sulphuric acid.

A novel thiourea derivative has been successfully synthesized green routes and fully characterized by FT-IR, H, C-NMR, and elemental analysis. The synthetic inhibitor 2-amino--(phenylcarbamothioyl) benzamide (APCB) was assessed as a corrosion inhibitor for mild steel (MS) in 0.5 M HSO.

Design, synthesis, molecular modelling and antitumor evaluation of -glucosylated rhodanines through topo II inhibition and DNA intercalation.

In the present study, 5-arylidene rhodanine derivatives , -glucosylation rhodanine , -glucosylation rhodanine , -glucoside rhodanine and -glucosylation 5-arylidene rhodanines were synthesised and screened for cytotoxicity against a panel of cancer cells with investigating the effective molecular target and mechanistic cell death. The anomers were separated by flash column chromatography and their configurations were assigned by NMR spectroscopy. The stable structures of the compounds under study were modelled on a molecular level, and DFT calculations were carried out at the B3LYP/6-31 + G (d,p) level to examine their electronic and geometric features.

Resorcinol Derivative as an Environmentally Friendly Low Carbon Steel Inhibitor in HCl Medium.

An ecofriendly resorcinol derivative, dimethyl-4,6-dihydroxyisophthalate (DDIP) is examined as an anticorrosion agent for low carbon steel (CS) in a 0.5 mol L HCl solution. Electrochemical and chemical methods are used to determine the effectiveness of the inhibitor.

New N-ribosides and N-mannosides of rhodanine derivatives with anticancer activity on leukemia cell line: Design, synthesis, DFT and molecular modelling studies.

N-ribosylation and N-mannosylation compounds have a great role in compounds activity as anticancer. The reaction of 2-thioxo-4-thiazolidinone (rhodanine) derivatives, as aglycon part, was done with ribofuranose and mannopyranose sugars (glycone part) followed by deacetylation without cleavage of the rhodanine under acidic medium. Conformational analysis has been studied using NMR methods (2D, DQF-COSY, HMQC and HMBC).

Molecular docking, molecular modeling, vibrational and biological studies of some new heterocyclic α-aminophosphonates.

A new diphenyl (aryl) (Ǹ-quinazolin-4-yl-hydrazino) methylphosphonates 3a-3d was synthesized via anhydrous zinc chloride catalyzed Kabachnic-Fields reaction. The structure of the synthesized compounds was confirmed by elemental analysis, FT-IR, H NMR, C NMR, P NMR and MS spectral data. The synthesized compounds showed significant antimicrobial and also remarkable cytotoxicity anticancer activities against breast carcinoma cell line (MCF7).

Aromatic ring size effects on the photophysics and photochemistry of styrylbenzothiazole.

The effect of ring size on the photophysics and photochemistry of styrylbenzothiazole has been investigated via systematic replacement of the phenyl ring of 1-phenyl-2-(2-benzothiazolyl)ethene with naphthyl and phenanthryl rings. Steady state absorption and fluorescence techniques have been employed to record the spectra in a variety of solvents, in conjunction with density functional theory (DFT) calculations, to probe absorption spectra and other properties of relevance to photo-excitation. Important experimental parameters were determined, such as fluorescence quantum yield and quantum yields of photochemical E-Z isomerisation.

Photophysical properties and semiempirical calculations of perylene-3,4,9,10-tetracarboxylic tetramethylester (PTME).

The spectral behavior and fluorescence quantum yield of perylene-3,4,9,10-tetracarboxylic tetramethylester (PTME) have been measured in different solvents. Both electronic absorption and fluorescence spectra are not sensitive to medium polarity. The dye exhibits high fluorescence quantum yield and high photostable.

Treatment-seeking behaviour for malaria in children under five years of age: implication for home management in rural areas with high seasonal transmission in Sudan.

Background: Effective management of malaria in children under the age of 5 requires mothers to seek, obtain, and use medication appropriately. This is linked to timely decision, accessibility, correct use of the drugs and follow-up. The aim of the study is to identify the basis on which fever was recognized and classified and exploring factors involved in selection of different treatment options.

Floating left atrial mass in a patient with mitral stenosis.

Mobile masses within the left atrial cavity are commonly caused by organized thrombi or left atrial myxoma. The use of transesophageal echocardiography has provided means for differentiation between the 2 conditions. We report a case of a left atrial mass in a female patient who presented with mitral stenosis and atrial fibrillation, and was diagnosed by transthoracic echocardiography (TTE).
