Magnetic field-dependent magnetization of highly crystalline FeO magnetic nanoparticles has been carried out to understand surface canting structures at low and room temperatures. The exchange bias () values of ∼18 to 27 Oe at 300 K for three samples prepared from different precursors are observed; and a decrease in value is obtained when the samples are measured at 5 K. However, with a decrease in temperature, coercivity () increases.

Moyamoya disease (MMD) is a vascular disorder characterized by steno-occlusive alterations in cerebral arteries, often resulting in ischemic or hemorrhagic events predominantly affecting the female population and more common in Asian populations. Despite its predominantly neurological manifestations, recent research suggests a potential association between MMD and cardiovascular diseases (CVDs). MMD involves various genetic and environmental factors, with mutations in the RNF213 gene being strongly implicated in disease susceptibility, with histopathological findings revealing intimal lesions and smooth muscle proliferation, contributing to vascular occlusion as well as dysregulation of circulating endothelial and smooth muscle progenitor cells further complicating MMD's pathogenesis.

The advancement of organic room temperature phosphorescence (RTP) materials has attracted considerable interest owing to their extensive applications. Their distinct advantages, including a metal-free composition, low toxicity, and facile synthesis under ambient conditions, make them highly desirable. This study examines the delayed fluorescence (DF) and RTP of metal-free, amorphous indenophenanthridine (IND)-based derivatives (1-10) and provides insights into molecular functionalisation and host matrix effects on delayed emission (RTP and DF).

The shape of cleaved tethered membranes.

Soft Matter

January 2025

Department of Chemistry, Columbia University, 3000 Broadway, New York, NY 10027, USA.

A remarkable property of flexible self-avoiding elastic surfaces (membranes) is that they remain flat at all temperatures, even in the absence of a bending rigidity or in the presence of active fluctuations. Here, we report numerical results of these surfaces wherein we alter their topology by systematically cleaving internal bonds. While it is known that a random removal of membrane bonds does not disrupt the overall extended shape of the membrane, we find that cleaving an elastic surface with longitudinal parallel cuts leads to its systematic collapse into a number of complex morphologies that can be controlled by altering the number and length of the inserted cuts.

The interaction of protein with nanoparticles (NPs) of varying shape and/or size boosts our understanding on their bioreactivity and establishes a comprehensive database for use in medicine, diagnosis, and therapeutic applications. The present study explores the interaction between lysozyme (LYZ) and different NPs like graphene oxide (GO) and zinc oxide (ZnO) having various shapes (spherical, 's', and rod-shaped, 'r') and sizes, focusing on their binding dynamics and subsequent effects on both the protein fibrillation and antimicrobial properties. Typically, GO is considered a promising medium due to its apparent inhibition and prolonged lag phase for LYZ fibrillation.

Background: Surgical methods of gingival depigmentation can be challenging, particularly if the gingival phenotype is thin due to the risk of gingival recession and bone exposure. Thus, exploring alternative, non-surgical, minimally invasive treatment modalities is warranted. In dermatology, vitamin C is extensively used for depigmentation and microneedling for collagen induction, with limited literature about its usage for improving gingival esthetics.

The coordination compounds featuring a {CuO} core, typically bridged by hydroxo or alkoxo groups, are particularly intriguing due to their notable magnetic properties and catalytic activity. In this study, we explored the synthesis and characterization of four new Schiff base ligands and their subsequent complexation with Cu salts, which resulted in the formation of three tetranuclear complexes: [Cu(L)]·2HO (1), [Cu(L)(HL)](Cl)(NO)·5HO (2), and [Cu(L)] (3), as well as one dinuclear complex: [Cu(L)] (4). These tetranuclear complexes all feature a {CuO} core, but with differing coordination environments around the Cu centers.

The orbital-free density functional theory (OF-DFT) based method is a convenient tool to carry out electronic structure calculations scaling almost linearly with the number of electrons. However, the main impediment in the application of this method is the unavailability of the accurate form for the non-interacting kinetic energy functional in terms of electron density. The Pauli kinetic energy functional is the unknown part of the kinetic energy functional, and the corresponding Pauli potential appears in the governing Euler equation.

Estimating rare event kinetics from molecular dynamics simulations is a non-trivial task despite the great advances in enhanced sampling methods. Weighted Ensemble (WE) simulation, a special class of enhanced sampling techniques, offers a way to directly calculate kinetic rate constants from biased trajectories without the need to modify the underlying energy landscape using bias potentials. Conventional WE algorithms use different binning schemes to partition the collective variable (CV) space separating the two metastable states of interest.

Potential of Type II NADH-Dehydrogenase in Antitubercular Drug Discovery.

ACS Infect Dis

January 2025

Department of Pharmaceutical Engg.Tech, IIT-Banaras Hindu University,Varanasi, Uttar Pradesh 221005, India.

The type II NADH-dehydrogenase enzyme in plays a critical role in the efficient functioning of the oxidative phosphorylation pathway. It acts as the entry point for electrons in the electron transport chain, which is essential for fulfilling the energy requirements of both replicating and nonreplicating mycobacterial species. Due to the absence of the type II NADH-dehydrogenase enzyme in mammalian mitochondria, targeting the type II NADH-dehydrogenase enzyme for antitubercular drug discovery could be a vigilant approach.

Nonplanar (butterfly-shaped) phenothiazine () and its derivative's () photophysical and spectral properties have been tuned by varying the solvents and their polarity and investigated employing spectroscopic techniques such as UV-Vis, steady-state and time-resolved fluorescence, and TDDFT calculations. The UV-Vis absorption studies and TDDFT calculations reveal two distinct bands for both compounds: a strong π-π* transition at shorter wavelengths and a weaker -π* transition, which displays a little bathochromic shift in polar solvents. The detailed emission studies reveal that such dual emission is a result of the photoinduced excited-state conjugation enhancement (ESCE) process.

Background: Oxidative stress is strongly linked to neurodegeneration through the activation of c-Abl kinase, which arrests α-synuclein proteolysis by interacting with parkin interacting substrate (PARIS) and aminoacyl tRNA synthetase complex-interacting multifunctional protein 2 (AIMP2). This activation, triggered by ataxia-telangiectasia mutated (ATM) kinase, leads to dopaminergic neuron loss and α-synuclein aggregation, a critical pathophysiological aspect of Parkinson's disease (PD). To halt PD progression, pharmacological inhibition of c-Abl kinase is essential.
