Peripheral GABAA receptor activation modulates rat tongue afferent mechanical sensitivity.

Objectives: The expression of GABA(A) receptors and the effects of GABAA receptor agonists on the response properties of tongue afferent fibres were investigated in female rats to determine if peripheral GABA receptors might be a target of topical benzodiazepines when used for pain relief in burning mouth syndrome patients.

Design: Nerve fibres in tongue sections from six female rats were identified using protein gene product 9.5, and the co-expression of the γ subunit of GABAA receptor and substance P assessed in the nerve fibres.

Nitric oxide release from trigeminal satellite glial cells is attenuated by glial modulators and glutamate.

Nitric oxide (NO) is suggested to play an important role in primary headaches. It has been proposed that release of NO from satellite glial cells (SGCs) of the trigeminal ganglion (TG) could contribute to the pathogenesis of these headaches. The principal aim of this study was to investigate if the phosphodiesterase inhibitor Ibudilast (Ibu) and 1α,25-dihydroxyvitamin D3 (Vit D3) could interfere with NO release from trigeminal SGCs.

SD-8, a novel therapeutic agent active against multidrug-resistant Gram positive cocci.

Anti-bacterial drug resistance is one of the most critical concerns among the scientist worldwide. The novel antimicrobial decapeptide SD-8 is designed and its minimal inhibitory concentration and therapeutic index (TI) was found in the range of 1-8 μg/ml and 45-360, respectively, against major group of Gram positive pathogens (GPP). The peptide was also found to be least hemolytic at a concentration of 180 μg/ml, i.

Development of novel peptide inhibitor of Lipoxygenase based on biochemical and BIAcore evidences.

Lipoxygenase (LOX) are enzymes implicated in a broad range of inflammatory diseases, cancer, asthma and atherosclerosis. These diverse biological properties lead to the interesting target for the inhibition of this metabolic pathway of LOX. The drugs available in the market against LOX reported to have various side effects.
