Context: The medications for metabolic syndromes are very minimal and the available are not effective and show adverse effects. There is a huge need for the development of effective and safe drugs to battle metabolic syndromes. In this context, our study aimed to decipher the key molecules from Artocarpus communis seed hexane fraction and their possible mechanism of action against metabolic syndrome.

Rigid, conjugated molecules are excellent candidates as molecular wires since they can achieve full extension between electrodes while maintaining conjugation. Molecular design can be used to minimize the accessible pi surface and interactions between the bridging wire and the electrode. Polyynes are archetypal molecular wires that feature a rigid molecular framework with a cross-section of a single carbon atom.

Phenomenological Modeling of Antibody Response from Vaccine Strain Composition.

Antibodies (Basel)

The elicitation of broadly neutralizing antibodies (bnAbs) is a major goal of vaccine design for highly mutable pathogens, such as influenza, HIV, and coronavirus. Although many rational vaccine design strategies for eliciting bnAbs have been devised, their efficacies need to be evaluated in preclinical animal models and in clinical trials. To improve outcomes for such vaccines, it would be useful to develop methods that can predict vaccine efficacies against arbitrary pathogen variants.

Significant research efforts have been devoted to improving the efficiency of catalytic carbon monoxide (CO) oxidation over α-FeO-based catalysts, but details of the underlying mechanism are still under debate. Here we apply the thermodynamic method (AITM) within the density functional theory framework to investigate the phase diagram of α-FeO(0001) surfaces with various terminations and the catalytic mechanism of CO oxidation on these surfaces. By extending the conventional AITM to consider the charge state of surface defects, we build the phase diagram of α-FeO(0001) surfaces in relation to the Fermi energy as well as the oxygen chemical potential, which makes it possible to explain the influence of point defects on the surface morphology and to predict the existence of the experimentally observed functional sites such as the ferryl group (FeO) and oxygen vacancies.
