From loose to tight: unveiling bond stretch isomerism in π-complexes of Li, Na and K.

The study investigates the phenomenon of bond stretch isomerism (BSI) in complexes formed between alkali metals (Li, Na, K) and various non-aromatic, aromatic hydrocarbons, as well as heteroaromatic systems. The research employs density functional theory (DFT) calculations to optimize complex geometries and analyze their electronic structures using molecular electrostatic potential (MESP), charge, and spin density analyses. The results reveal that these complexes can exist in two distinct configurations: 'loose' long-bond isomers (lbi) that retain the original hydrocarbon geometry and 'tight' short-bond isomers (sbi) that undergo geometrical distortion upon complexation, with sbi generally being more stable.

To study the Impact of Otoendoscopy at the end of apparent microscopic clearance of disease during primary Cholesteatoma surgery in detecting the residual cholesteatoma. A prospective, interventional, non randomized and non comparative study was conducted at the ESIC Medical College and PGIMSR. All patients of chronic otitis media of squamosal type undergoing modified radical mastoidectomy were included in the study.

Graph Neural Network-Based Drug Gene Interactions of Wnt/β-Catenin Pathway in Bone Formation.

Introduction The Wnt/β-catenin pathway is crucial for bone formation and remodeling, regulating osteoblast differentiation, bone remodeling, and skeletal homeostasis. Dysregulation of the Wnt/β-catenin pathway is linked to bone-related diseases like osteoporosis, osteoarthritis, and osteosarcoma. The strategies to modulate this pathway include Wnt agonists, inhibitors, and small molecules.

Fluorophore-quencher complexes (Cu/Al) of coumarin Schiff bases as chemosensors for the detection of L-glutamic acid and L-arginine: and studies.

This study reports the development of new probes RR1 ((1)-1-(1-(6-bromo-2-oxo-2-chromen-3-yl)ethylidene)ethyl thiosemicarbazone) and RR2 ((1)-1-(1-(6-bromo-2-oxo-2-chromen-3-yl)ethylidene)phenyl thiosemicarbazone), which selectively showed fluorescence turn 'OFF' response towards Cu and Al. Further, complexes of RR1-Cu2+ and RR2-Al3+ acted as chemosensors for the detection of L-amino acids. RR1-Cu2+ selectively detected L-arginine (fluorescence turn 'ON'), and RR2-Al3+ selectively detected L-glutamic acid (fluorescence turn 'ON').

A comparative study of the efficacy of alginate lyases in the presence of metal ions elevated in the cystic fibrosis lung milieu.

, a common cause of morbidity in cystic fibrosis, chronically infects the patient's lungs by forming an alginate-containing biofilm. Alginate lyases are polysaccharide lyases that lyse alginate and are, therefore, potential biofilm-disruptive agents. However, cystic fibrosis sputum contains high levels of metals such as iron and zinc.

Multiplex Loop-Mediated Isothermal Amplification Coupled Lateral Flow Assay for Point-of-Care Detection of Syphilis.

Unlabelled: Syphilis is a re-emerging sexually transmitted disease caused by the pathogenic spirochete Every year more than 5 million cases are reported globally. The current diagnostic methods are primarily based on serological assays, which are less sensitive at an early stage of infection. To improve the disease diagnosis, there is a need to develop a rapid, simple, sensitive, and cost-effective point-of-care application, which plays an effective role in the detection of syphilis infection.

Harnessing the acceptor substrate promiscuity of Clostridium botulinum Maf glycosyltransferase to glyco-engineer mini-flagellin protein chimeras.

Several bacterial flagellins are O-glycosylated with nonulosonic acids on surface-exposed Serine/Threonine residues by Maf glycosyltransferases. The Clostridium botulinum Maf glycosyltransferase (CbMaf) displays considerable donor substrate promiscuity, enabling flagellin O-glycosylation with N-acetyl neuraminic acid (Neu5Ac) and 3-deoxy-D-manno-octulosonic acid in the absence of the native nonulosonic acid, a legionaminic acid derivative. Here, we have explored the sequence/structure attributes of the acceptor substrate, flagellin, required by CbMaf glycosyltransferase for glycosylation with Neu5Ac and KDO, by co-expressing C.

Impact of eugenol on biofilm development in Shigella flexneri 1457: a plant terpenoid based-approach to inhibit food-borne pathogen.

Shigella flexneri is a gram-negative bacterium responsible for shigellosis and bacterial dysentery. Despite using various synthetic antimicrobial agents and antibiotics, their efficacy is limited, prompting concerns over antibiotic resistance and associated health risks. This study investigated eugenol, a polyphenol with inherent antioxidant and antibacterial properties, as a potential alternative treatment.

A comparative study of the substrate preference of the sialidases, CpNanI, HpNanH, and BbSia2 towards 2-Aminobenzamide-labeled 3'-Sialyllactose, 6'-Sialyllactose, and Sialyllacto-N-tetraose-b.

Sialidases catalyze the removal of terminal sialic acids from sialylated biomolecules, and their substrate preference is frequently indicated in terms of the glycosidic linkages cleaved (α2-3, α2-6, and α2-8) without mention of the remaining sub-terminal reducing-end saccharide moieties. Many human gut commensal and pathogenic bacteria secrete sialidases to forage for sialic acids, which are then utilized as an energy source or assimilated into membrane/capsular structural components. Infant gut commensals similarly utilize sialylated human milk oligosaccharides containing different glycosidic linkages.
