CCR6 signaling inhibits suppressor function of induced-Treg during gut inflammation.

CCR6 is a G protein-coupled receptor (GPCR) that binds to a specific chemokine, CCL20. The role of CCR6-CCL20 is very well studied in the migration of immune cells, but the non-chemotaxis functions of CCR6 signaling were not known. Here, we show that during gut inflammation, the frequency of Foxp3CD4 T cells (Tregs) reduced in the secondary lymphoid tissues and CCR6 Tregs enhanced the expression of RORγt.

Theoretical insights on flavanones as antioxidants and UV filters: A TDDFT and NLMO study.

UV radiations can cause several irritations to the skin like sunburn, photo aging and even skin cancer. Sunscreens are widely used to protect the skin against these harmful radiations. One of the ingredients present in these sunscreens are organic molecules capable of absorbing these harmful radiations.

A DFT based analysis of adsorption of Hg ion on chitosan monomer and its citralidene and salicylidene derivatives: Prior to the removal of Hg toxicity.

A Density functional theory based study of adsorption of the toxic metal Hg (II) ion by chitosan monomer and two of its derivatives; citralidene and salicylidene chitosan, has been performed. The effect of structural features on the stability of studied complexes has been analyzed by using Gaussian03 software package. All the possible conformations of these adsorbents were studied using the global minimum geometries.

Flexible chitosan-nano ZnO antimicrobial pouches as a new material for extending the shelf life of raw meat.

As a breakthrough to open up the industrial use of novel environmentally benign packaging material, we propose the first report on portable chitosan-ZnO nano-composite pouches that will serve as elite entrants in smart packaging. A facile, one pot procedure was adopted for the preparation of the C-ZnC films. In order to tune the property of C-ZnC films, four different composite films were prepared by varying the concentration of ZnO.
