Metabarcoding reveals differences in fungal communities between unflooded versus tidal flat soil in coastal saline ecosystem.

In the saline-affected ecosystem, fungi have huge potential to promote growth, induce disease resistance and enhance tolerance against salt-stress of host plants. Since areas of plowland are gradually decreasing, the reclamation of coastal saline lands could play a crucial role in maintaining agricultural productivity and crop security globally. Therefore, it is of great significance to explore the fungal diversity in the coastal saline ecosystem.

Dapsone: An Update.

Dapsone is an extensively Used drug for the treatment of leprosy as well as'some other clinical problems worldwide: Its use has been predicted to increase further, especially in non leprosy conditions. Treatment with Dapsone is sometimes known'to be associated with side-effects, which include gastrointestinal intolerance, haemolysis, methaemoglobinaemia, agranulocytosis, psychosis, peripheral neuritis and varied dermatological conditions, varying from simple rash to severe life threatening epidermolytic reactions and Dapsone hypersensitivity syndrome (DHS). DHS is a rare delayed hypersensitivity reaction involving multiple organs.

Computational analysis of the structural basis of ligand binding to the crustacean retinoid X receptor.

Homodimerization of the retinoid X receptor (RXR) occurs upon binding of ligands to the receptor, but little is known about structural mechanisms involved in RXR ligand binding. In the present study, binding of known ligands (5-Hydroxytryptamine, dopamine and naloxone) to the Celuca pugilator RXR was modeled computationally using the human RXR-α as a homology template. Docking scores calculated for these ligands showed reasonably good binding interactions to C.

Biophysical analyses of human resistin: oligomer formation suggests novel biological function.

Resistin, a small secreted peptide initially identified as a link between obesity and diabetes in mice, was shown to be involved in mediating inflammation in humans. We had shown earlier that recombinant human resistin has a tendency to form aggregates by formation of inter/intramolecular disulfide linkages and that it undergoes a concentration-dependent conformational change in secondary structure from alpha-helical to beta-sheet form. Here we report that this change in secondary structural conformation is due to the increase in the oligomeric form of human resistin as a function of protein concentration.

A 50-kDa ERK-like protein is up-regulated by a dual altered peptide ligand that suppresses myasthenia gravis-associated responses.

Myasthenia gravis (MG) and its animal model, experimental autoimmune MG (EAMG), are T cell-dependent antibody-mediated autoimmune diseases. A dual altered peptide ligand (APL) that is composed of the tandemly arranged two single amino acid analogues of two myasthenogenic peptides, p195-212 and p259-271, down-regulated in vitro and in vivo MG-associated autoreactive responses. The dual APL was shown to exert its beneficial effects by up-regulating ERK1,2 in CD4(+)CD25(+) regulatory cells.
