Electrospun nanofibers for localized drug release of a neuroprotective natural extract of Usnea ghattensis.

This research is based on the incorporation of the methanolic extract of the Usnea ghattensis into poly (caprolactone) (PCL) nanofibers (NFs) to investigate the capacity in reducing reactive oxygen species (ROS). PCL-NFs were fabricated by the electrospinning technique and are investigated as potential dressing material focused on the release of usnic acid (PCL-USNIC NFs), and its encapsulation efficiency and kinetic release were analyzed by high performance liquid chromatography (HPLC). This investigation was performed by analyzing the usnic acid concentration as a function of the distance from the mat center point.

In Vitro Mechanistic Studies of a Standardized Sustainable Grape Seed Extract for Potential Application as a Mood-Modulating and Cognition-Enhancing Supplement.

Background: Grape seed extract (GSE) from L. is rich in polyphenols and oligomeric proanthocyanidin complexes (OPCs), and it has shown potential benefits in managing low mood and cognitive function. In this study, we investigated the potential bioactivities of Enovita, a standardized GSE extract (GSEe herein) rich in OPCs, in key mechanistic pathways related to low mood conditions and cognitive function.

Superoxidase dismutase (SOD) topical use in oncologic patients: treatment of acute cutaneous toxicity secondary to radiotherapy.

Objective: The objective of this study is to evaluate the efficiency of SOD applied topically in oncologic patients affected by acute radiodermatitis.

Materials And Method: This study includes 57 patients who showed a dermatitis grade 2 or superior; they were administered SOD ointment b.i.

Agonists determine the pattern of G-protein activation in mu-opioid receptor-mediated supraspinal analgesia.

The opioids heroin, methadone, buprenorphine, and morphine produce supraspinal antinociception in CD-1 mice that is antagonized by Cys(2), Tyr(3), Orn(5), Pen(7)-amide but not by naltrindole or nor-binaltorphimine. The patterns of GTP-binding regulatory proteins (G-proteins) activation exhibited by these agonists at mu-opioid receptors were characterized. The expression of alpha-subunits of Gi-protein classes, Gi1, Gi2, Gi3, Go1, Go2 and Gz, and those of the Gq-protein family, Gq and G11, was reduced by administration of antisense oligodeoxynucleotides (ODNs) complementary to sequences in their respective mRNAs.
