47f: Bioadaptation to Low Doses of Xenobiotics in Aquaculture.

Agricultural and industrial activities are increasing pollution of water bodies with low doses of xenobiotics that have detrimental effects on aquaculture. The aim of this work was to determine the possibility of using 47f culture in fish aquaculture under the influence of low doses of xenobiotics as an adaptogen. An increase in the survival of individuals exposed to the xenobiotic bisphenol A solution and fed with the 47f was shown compared to control groups and, at the same time, the cytokine profile in the intestinal tissues of was also investigated.

Comparative Study of the Results of Operations in Patients with Tumor and Non-Tumor Obstructive Jaundice Who Received and Did Not Receive Antioxidant Therapy for the Correction of Endotoxemia, Glycolysis, and Oxidative Stress.

Purpose: To compare the results of surgical treatment and changes in biomarkers of cholestasis, endotoxicosis, cytolysis, lipid peroxidation, glycolysis disorders, and inflammation in patients with benign and malignant obstructive jaundice (OJ) in patients receiving and not receiving antioxidant pharmacotherapy (AOT).

Patients And Methods: The study included 113 patients (aged 21-90 years; 47 males and 66 females) who received surgical intervention for OJ due to non-malignant (71%) or malignant tumor (29%) etiologies. Patients were divided into two groups: Group I ( = 61) who did not receive AOT and Group II ( = 51) who received AOT (succinate-containing drug Reamberin) as part of detoxification infusion therapy.

Meglumine acridone acetate, the ionic salt of CMA and N-methylglucamine, induces apoptosis in human PBMCs via the mitochondrial pathway.

Meglumine acridone acetate (MA) is used in Russia for the treatment of influenza and other acute respiratory viral infections. It was assumed, until recently, that its antiviral effect was associated with its potential ability to induce type I interferon. Advanced studies, however, have shown the failure of 10-carboxymethyl-9-acridanone (CMA) to activate human STING.

Phonon spectra, electronic, and thermodynamic properties of WS nanotubes.

Hybrid density functional theory calculations are performed for the first time on the phonon dispersion and thermodynamic properties of WS -based single-wall nanotubes. Symmetry analysis is presented for phonon modes in nanotubes using the standard (crystallographic) factorization for line groups. Symmetry and the number of infra-red and Raman active modes in achiral WS nanotubes are given for armchair and zigzag chiralities.

First-principles modeling of hafnia-based nanotubes.

Hybrid density functional theory calculations were performed for the first time on structure, stability, phonon frequencies, and thermodynamic functions of hafnia-based single-wall nanotubes. The nanotubes were rolled up from the thin free layers of cubic and tetragonal phases of HfO . It was shown that the most stable HfO single-wall nanotubes can be obtained from hexagonal (111) layer of the cubic phase.

Novel free fatty acid receptor 1 (GPR40) agonists based on 1,3,4-thiadiazole-2-carboxamide scaffold.

Free fatty acid receptor 1 (FFA1), previously known as GPR40 is a G protein-coupled receptor and a new target for treatment of type 2 diabetes. Two series of FFA1 agonists utilizing a 1,3,4-thiadiazole-2-caboxamide scaffold were synthetized. Both series offered significant improvement of the potency compared to the previously described 1,3,4-thiadiazole-based FFA1 agonists and high selectivity for FFA1.

Novel agonists of free fatty acid receptor 1 (GPR40) based on 3-(1,3,4-thiadiazol-2-yl)propanoic acid scaffold.

1,3,4-Thiadiazole was explored as a more polar, heterocyclic replacement for the phenyl ring in the 3-arylpropionic acid pharmacophore present in the majority of GPR40 agonists. Out of 13 compounds synthesized using a flexible, three-step protocol (involving no chromatographic purification), four compounds were confirmed to activate the target in micromolar concentration range. While the potency of the series should be subject of further optimization, the remarkable aqueous solubility and microsomal stability observed for the lead compound (8g) apparently attests to this new scaffold's high promise in the GPR40 agonist field.

Transcarotid balloon occlusion of the brachiocephalic artery to control bleeding due to sharp injuries of the right subclavian artery.

We present a new manoeuvre of transcarotid balloon occlusion of the brachiocephalic artery to control bleeding due to sharp injuries of the right subclavian artery. To control the bleeding, we employed a temporary balloon occlusion of the brachiocephalic artery with a 6.0 Fogarty balloon catheter, which was introduced through ECA retrogradely into the aorta, inflated and pulled back.

Nanostructured organosilicon luminophores and their application in highly efficient plastic scintillators.

Organic luminophores are widely used in various optoelectronic devices, which serve for photonics, nuclear and particle physics, quantum electronics, medical diagnostics and many other fields of science and technology. Improving their spectral-luminescent characteristics for particular technical requirements of the devices is a challenging task. Here we show a new concept to universal solution of this problem by creation of nanostructured organosilicon luminophores (NOLs), which are a particular type of dendritic molecular antennas.
