Summary: Antibacterial materials have gained popularity in the market and everyday life, but the use of synthetic chemicals in these materials negatively impacts the environment and contributes to antibacterial resistance. This study aims to find an eco-friendly solution using natural antibacterial components extracted from neem leaves to treat jute-cotton blended (jutton) yarn. The treated jutton yarn showed strong antibacterial activity against both gram-positive and gram-negative bacteria, and the interaction between the neem leaves and the yarn provided long-lasting antibacterial performance.

Summary: The decomposition of Azadirachta indica leaves can negatively affect the germination and growth of Myracrodruon urundeuva, with lower concentrations showing more significant effects during the first decomposition period. Residues of the leaves also impact the root and stem length, total biomass, and chlorophyll content of M. urundeuva. The study suggests the allelopathic action of compounds in A. indica litter and cautions against its use in areas requiring ecological restoration and in natural environments.

Summary: The use of C2 servers in cyberattacks has increased significantly, with attackers using DGA technique to hide their servers. Existing techniques for binary classification of domain names have issues with real-time detection and sensitivity to data. This paper proposes the DTFS-DGA model, which combines neural networks and traditional machine learning models to detect DGA in real-time without relying on reverse engineering and being insensitive to data size.

Summary: Molecular mechanics are important for enzyme action and understanding loop motion dynamics is crucial for designing enzyme inhibitors. In this study, we investigated the structural dynamics of NS2B/NS3 dengue protease for the development of new protease inhibitors. The internal dynamics of two regions, fingers 1 and 2, adjacent to the active site triad were found to control the enzyme action. Correlated motions in the beta-turns of these regions modulated the enzyme activity. Perturbation of these motions by cosolvent concentration, temperature, and mutations affected the enzyme kinetics.

Summary: In this study, the impact of a compound called naringenin on the aggregation and fibril formation of α-synuclein, which is linked to the pathology of Parkinson's disease, was investigated. The findings showed that naringenin effectively inhibits aggregation and fibril formation, thereby delaying the progression of Parkinson's disease. The compound was incorporated onto the surface of gold nanoparticles and demonstrated the ability to interact with α-synuclein and alter the absorption spectrum of the nanoparticles. Additionally, naringenin and its nanocomplex did not affect neuronal cell viability.

Summary: In this study, an environment friendly solid state synthesis method was used to successfully synthesize a molecular complex, 2-(3-Hydroxyphenyl)-2,3-dihydroquinazolin-4(1H)-one (ANHB), with the highest yield. The compositional behavior of composites in the entire range was determined by analyzing the phase diagram of anthranilamide (AN) 3-hydroxybenzaldehyde (HB) system, which identified the formation of two eutectics and a molecular complex. The novelty and structural behavior of ANHB were studied using various techniques such as FTIR, NMR, UV-vis, fluorescence, DSC, and PXRD. The thermodynamic properties of the eutectics and complex were characterized using the heat of fusion values obtained from DSC. The single crystal XRD (SCXRD) and atomic packing studies confirmed that ANHB crystallizes in a centro-symmetric triclinic space group P 1 with two molecules in the asymmetric unit and four molecules in the unit cell. The synthesized complex exhibited fluorescence emission in the visible region.

Summary: A novel benzo[a]phenoxazine-based fluorescent dye LV2 was used to investigate the recognition of a linker histone protein H1 by calf-thymus DNA (DNA). The fluorescence lifetime and rotational relaxation time of LV2 buried in H1 or DNA showed significant changes upon the formation of the H1-DNA complex, indicating successful recognition between H1 and DNA. Molecular docking and molecular dynamics simulations demonstrated that the binding of LV2 in the interface of the H1-DNA complex was energetically more favorable. Through the significant changes in fluorescence lifetime and rotational relaxation time, the benzo[a]phenoxazine-based fluorescent dye reported on the recognition of H1 by DNA.

Summary: Parkinson's disease is an age-related neurological disorder caused by aggregates of alpha-synuclein (aS) proteins. In this study, the structure and aggregation behavior of two artificial single point mutants of aS were analyzed and compared to the wild-type. The mutants showed enhanced structural stability and alpha-helical propensity, resulting in slower fibril formation and reduced toxicity to neuronal cells.
