Background: In the modern medical industry, sensors and other medical electronic equipment such as ECG, thermometers, etc. that measure vitals like blood pressure, body temperature, heartbeat, and blood cells are used to record patient data. The information gathered helps to create a patient profile, which in turn helps doctors treat patients appropriately and helps users gain insights into their health.

Myasthenia gravis (MG) is characterized by muscle weakness and fatigability. The presence of autoantibodies against the acetylcholine receptors (AChR) at the neuromuscular junction, which impairs neuromuscular transmission, is the hallmark of the disease. However, a minority of patients have antibodies against muscle-specific tyrosine kinase (MuSK), which is referred to as MuSK myasthenia gravis (MuSK-MG).

Probiotics have attained significant interest in recent years as a result of their gut microbiome modulation and gastrointestinal health benefits. Numerous fermented foods contain lactic acid bacteria (LAB) which are considered as GRAS and probiotic bacteria. The present study aimed to investigate indigenous LAB from homemade fermented milk samples collected in remote areas of Karnataka (India), in order to isolate the most potent and well-adapted to local environmental conditions bacteria, which were then evaluated using a step-by-step approach focused on the evaluation of probiotic traits and β-galactosidase-producing ability.

Six different acylthiourea ligands (L1-L6) and their corresponding Ru(II)--cymene complexes (P1-P6) were designed to explore the structure-activity relationship of the complexes upon aliphatic chain and aromatic conjugation on the C- and N-terminals, respectively. The compounds were synthesized and adequately characterized using various analytical and spectroscopic techniques. The structures of P2-P6, solved using single crystal X-ray diffraction (XRD), confirmed the neutral monodentate coordination of the S atoms of the acylthiourea ligands to Ru(II) ions.

Article Synopsis
  • A water-soluble binuclear organometallic Ru--cymene complex was synthesized from a specific ligand and ruthenium chloride, using methanol at room temperature.
  • The structure was confirmed using various spectroscopy techniques and single crystal X-ray diffraction, revealing a piano-stool geometry around the Ru(II) ion.
  • The complex demonstrated higher cytotoxicity against certain cancer cell lines compared to cisplatin and showed potential antiviral activity against SARS-CoV-2 proteins in molecular docking studies.

Two heterocyclic azole compounds, 3-(2,3-dihydrobenzo[d]thiazol-2-yl)-4H-chromen-4-one () and 5-(1H-indol-3-yl)-4-methyl-2,4-dihydro-3H-1,2,4-triazole-3-thione () were obtained unexpectedly from 2-aminothiophenol and 4-oxo-4H-chromene-3-carbaldehyde (for ), and ()-2-((1H-indol-3-yl)methylene)-N-methylhydrazine-1-carbothioamide in the presence of anhydrous FeCl (for ), respectively. The compounds were well characterized by analytical and spectroscopic tools. The molecular structures of both the compounds were determined by single crystal X-ray diffraction (XRD) study.

The sensitivity of protein molecular structures makes them susceptible to aggregation in conditions unfavorable for the maintenance of their native folds. The aggregation of proteins leads to many disorders, but the inhibition of amyloid fibril formation using metal-containing small molecules is gaining popularity. Herein we report the effect of nickel(II) complexes (N1, N2, N3, and N4) bearing thiosemicarbazones on the inhibition of amyloid fibril formation by insulin.

Fungal spoilage and toxic biogenic amine production is a major risk in fermented products. Therefore, the selection of nontoxic biogenic amines producing probiotic bacteria plays a vital role in the fermentation process. In the present study, a total of 18 bacterial isolates were isolated from eight different homemade pickle samples and 15 lactic acid bacteria (LAB) were identified based on biochemical tests.

Lichens comprise highly diverse and complex microbial communities, the majority consisting of mycobiont, photobiont, Basidiomycetes yeast and bacteriobiont (internal bacterial communities). In this study, bacterial diversity of foliose lichen was reported. Next generation sequence (NGS) such as Illumina Sequencing (150*2) of 16S rRNA (V3 and V6 region) was used to delineate the bacterial communities associated with five foliose lichen samples.

Background: Inflammation is a key element in tumor progression, over time, persistent inflammation causes damage to DNA and leads to cancer. The relationship between chronic inflammation and tumor development is well established, blocking of which can help in cancer prevention and treatment in the future.

Objective: Hence, with this background, the present study aims to evaluate the anti-inflammatory and anticancer potential of Cassia auriculata (CA) solvent fractions through in silico and in vitro means, respectively.

Background: Celiac disease is an intestinal chronic disorder with multifactorial etiology resulting in small intestinal mucosal injuries and malabsorption. In genetically predisposed individuals with HLA DQ2/DQ8 molecules, the gluten domains rich in glutamine and proline present gluten domains to gluten reactive CD4 T cells causing injury to the intestine. In the present experimental design, the indigenous bacteria from wheat samples were studied for their gluten hydrolyzing functionality.

Osmotic demyelination syndrome results from overly rapid serum sodium correction and is often iatrogenic. We report a 50-year-old hypertensive woman on Indapamide presenting with malaise, dizziness and serum sodium less than 100mmol/l who developed osmotic demyelination syndrome after correction of the hyponatremia. Good neurological recovery was seen after plasmapheresis.
