Background: In graph theory, M polynomials like the matching polynomial are very crucial in examining the matching structures within graphs, while NM polynomials extends this to analyze non-matching edges. These polynomials are important in many fields, including chemistry and network architecture. They support the derivation of topological indices for protein structure analysis, network communication optimization, and drug design in QSAR/QSPR investigations.

Article Synopsis
  • This research investigates the chemical treatment of novel ligno-cellulose fibers extracted from the bark of the Careya arborea plant, which is native to the Indian subcontinent and Afghanistan.
  • The fibers contain a significant amount of cellulose (71.17 wt%) and hemicellulose (27.86 wt%) and exhibit low density (1140 kg/m), making them ideal for lightweight applications across various industries.
  • Chemical treatments using NaOH at different concentrations successfully altered the fibers' structure, enhancing their thermal stability and mechanical properties, thereby offering promising solutions for high-temperature and sustainable applications.

Addiction is a serious public health problem, and the current pharmacotherapy is unable to prevent drug use reinstatement. Studies have focused on physical exercise as a promising coadjuvant treatment. Our research group recently showed beneficial neuroadaptations in the dopaminergic system related to amphetamine-relapse prevention involving physical exercise-induced endogenous opioid system activation (EXE-OS activation).

Background: The unrestricted application of antibiotics increased antimicrobial resistance in bacteria through horizontal gene transfer of resistant genes from the pathogenic sources and the evolution of multi-drug resistance organisms. The application of antibiotics caused severe risk to human health because animals may transmit diseases to humans. Hence, the search of novel antimicrobial agents from microbial sources is an urgent need.
