In this paper, a molecular dynamics (MD) approach based on classical valence bond (VB) theory, referred to as AIVBMD, is presented. To validate AIVBMD, a novel algorithm that enables efficient computation of energy gradients based on nonorthogonal orbitals is introduced. Taking the gas-phase S2 reaction as an example, a compact VB wave function gives reasonable accuracy with only 27 VB structures, compared to the full active space of 5292 VB structures.

Oral probiotic biotherapies hold significant promise for addressing intestinal inflammatory disorders. Nonetheless, due to the challenging pathological microenvironment of the gastrointestinal tract, it is difficult to achieve deliver probiotics in an inflammation-targeted manner while improving their intestinal colonization and minimizing the impact of gastrointestinal environment on their vitality. To address this, an innovative probiotics oral delivery system (EcN-Apt@HG) against ulcerative colitis (UC) was developed by conjugating IL-6 aptamer to the surface of EcN and subsequently encapsulating the probiotics in a hydrogel consisting of aldehyde-functionalized chondroitin sulfate (CS) and Poly(amidoamine) (PAMAM).

Meeting the needs of a growing population calls for a change from linear production systems that exacerbate the depletion of finite natural resources and the emission of environmental pollutants. These linear production systems have resulted in the human-driven perturbation of the Earth's natural biogeochemical cycles and the transgression of environmentally safe operating limits. One solution that can help alleviate the environmental issues associated both with resource stress and harmful emissions is resource recovery from waste.
