Advances in Manufacturing a New Cable Coating Resistant to Thermal Aging and γ Rays by Cobalt-60 up to 50 KGy.

Poly(vinyl chloride) (PVC) is widely used for covering electrical cables, but a decrease in its physicochemical, thermal, and mechanical properties has been observed over time. Poly(nitrile butadiene) rubber (NBR), due to its certain properties, was chosen to be blended with PVC to improve its specific properties, when used as insulation for electrical cables installed in nuclear power plants. Thus, this work focuses on the effect of γ radiation at doses ranging from 10 to 50 KGy on the physicochemical, thermal, morphological, and mechanical properties of PVC, as well as on the improvement of its properties by the incorporation of NBR in the PVC matrix as a blend.

Antimicrobial Activity of Novel Ni(II) and Zn(II) Complexes with (E)-2-((5-Bromothiazol-2-yl)imino)methyl)phenol Ligand: Synthesis, Characterization and Molecular Docking Studies.

In order to address the challenges associated with antibiotic resistance by bacteria, two new complexes, Ni(II) and Zn(II), have been synthesized using the conventional method based on Schiff base ligand (E)-2-((5-bromothiazol-2-yl) imino) methyl) phenol. The Schiff base ligand (HL) was synthesized using salicylaldehyde and 5-(4-bromophenyl)thiazol-2-amine in both traditional and efficient, ecologically friendly, microwave-assisted procedures. The ligand and its complexes were evaluated by elemental analyses, FTIR spectroscopy, UV-Vis spectroscopy, nuclear magnetic resonance (NMR), thermogravimetric analysis (TGA) and magnetic susceptibility.

An integrative GC-MS and LC-MS metabolomics platform determination of the metabolite profile of L. root, and in silico & in vitro evaluation of its antibacterial & antidiabetic activities.

The L. tree is a member of the family and the genus Bombax. Both Chinese and Indian traditional medicine have made extensive use of it in the treatment of sickness.

Characterization and adsorption of malachite green dye from aqueous solution onto L. (Willow tree) leaves powder and its respective biochar.

In the present study, the use of low-cost, highly efficient, eco-friendly, and abundantly available (in Kashmir region, J&K India) willow leaves from which adsorbents like willow leaves powder (WLP) and willow leaves biochar (WLB) were prepared, have been found to be efficient for malachite green (MG) dye removal and can be used as an alternative to the current expensive methods of removing the same dye from an aqueous solution. The techniques like Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and carbon, hydrogen, nitrogen, sulphur (CHNS) analyser were used to characterize the samples without any chemical treatment. SEM of the adsorbents shows the presence of different sized pores, cracks, and crevices.

MiR-624-5p enhances NLRP3 augmented gemcitabine resistance via EMT/IL-1β/Wnt/β-catenin signaling pathway in ovarian cancer.

The current study investigates the NLRP3's cytotoxicity inhibitory effect among ovarian cancer cells and how it interacts with Wnt/β-catenin in vitro conditions. Further, the study also analyzed the regulatory role of NLRP3 in resistance to gemcitabine among ovarian cancer cells and its underlying interaction mechanisms with Wnt/β-catenin in vitro. The current in vitro study detailed that when downregulating NLRP3, it could enhance the gemcitabine sensitivity in GRC cells.

Mathematical modeling for the outbreak of the coronavirus (COVID-19) under fractional nonlocal operator.

A mathematical model for the spread of the COVID-19 disease based on a fractional Atangana-Baleanu operator is studied. Some fixed point theorems and generalized Gronwall inequality through the AB fractional integral are applied to obtain the existence and stability results. The fractional Adams-Bashforth is used to discuss the corresponding numerical results.

High performance liquid chromatographic assay of amlodipine, valsartan and hydrochlorothiazide simultaneously and its application to pharmaceuticals, urine and plasma analysis.

A Simple, Specific, Precise, Accurate, Linear, Rugged, Robust High Performance Liquid Chromatographic method of analysis for simultaneous determination of assay of Amlodipine, Valsartan and Hydrochlorothiazide drugs in the pharmaceuticals tablet formulations using Pioglitazone as a common internal standard was developed and validated. The assay was accomplished using a mixture of acetonitrile & methanol in the volume ratio of 20:80 v/v (mobile phase B) and Ammonium acetate buffer (Mobile phase A) in gradient flow as mobile phase on an Hibar RP-18e, 250 × 4.6 mm, 5µ as chromatographic column at a flow rate of 1.

The effect of prednisolone on endometrial VGEF concentrations, Gene polymorphisms and pregnancy outcome in women with polycystic ovary syndrome: A retrospective cohort study.

PCOS (Polycystic Ovary Syndrome) occurs due to hyperandrogenism, excessive androgen, abnormal growth, steroidogenesis and seems to be associated with abnormal Vascular endothelial growth factor (VEGF) level in serum. The treatment is provided on the basis of body symptoms to mute the excess production of hormone. The study assessed the effect of prednisolone treatment on the concentration of VEGF, pregnancy outcomes and variants of VEGF SNPs.

Hospital based serological evidence of rickettsial diseases and assessment diagnostic tests of pyrexia of unknown origin.

The present study examined hospital-based serological tests of rickettsial infections and assessment for diagnosis of pyrexia of unknown origin (PUO). Blood samples were tested for Weil Felix antigens, ELISA for scrub typhus group and polymerase chain reaction (PCR) to detect the presence of DNA of spotted and scrub typhus group with the help of specific oligonucleotide. We tested 450 patient samples and found 101 Weil Felix-positive with 15 having ≥320 titres.

Analysis of VEGF gene polymorphisms and serum VEGF protein levels contribution in polycystic ovary syndrome of patients.

Vascular endothelial growth factor (VEGF) is a well-known factor in reproductive function and contributes to the pathogenesis of polycystic ovary syndrome (PCOS). Genetic variations in VEGFA gene were suggested to contribute alterations in VEGF secretion and PCOS. This study evaluated the association of VEGFA SNPs with altered VEGF secretion level and PCOS among ethnically-matched control women.

Molecular characterization of Clostridium difficile isolated from carriage and association of its pathogenicity to prevalent toxic genes.

Background: There are reports of non-toxigenic C. difficile strains from asymptomatic carriers are increasing source of transmission. Asymptomatic carriage transmission in the hospital or community settings might have changed over the years.

Isolation and characterization of lectin with antibacterial, antibiofilm and antiproliferative activities from Acinetobacter baumannii of environmental origin.

Aims: Lectin is a nonimmunogenic glycoprotein that has been extracted mostly from the primary plant source leguminoase. Its ability to precisely recognize and bind to the complex cell bound structure enables it to play diverse roles. In this study, we obligate to define new sources of lectins since the production of lectins is very expensive.
