Objective: The present study has the following objectives: 1) identify differentially expressed proteins and pathways in blood samples of BD compared to healthy controls by employing high-throughput proteomics and bioinformatics and 2) characterize disease-related molecular signatures through in-depth analysis of the differentially expressed proteins and pathways.

Methods: Blood samples from BD patients (n=10) classified into high (BD+) or poor functioning (BD-), based on functional and cognitive status, and healthy controls (n=5) were analyzed using mass spectrometry-based proteomic analysis. Bioinformatics was performed to detect biological processes, pathways, and diseases related to BD.

Biopharmanet-TEC, Interdepartmental Centre for Innovation in Health Products, University of Parma, Italy; Department of Pharmacy, University of Parma, Italy; Graduate School of Health - Pharmacy, University of Technology Sydney, Australia. Electronic address:

Lecithin and hyaluronic acid were used for the preparation of polysaccharide decorated nanoparticles loaded with vitamin E using the cationic lipid dioctadecyldimethylammonium bromide (DODMA). Nanoparticles showed mean particle size in the range 130-350 nm and narrow size distribution. Vitamin E encapsulation efficiency was higher than 99%.

Pelvic inflammatory disease (PID) is a gynaecological inflammatory disorder with a high incidence that can lead to sequelae such as infertility, ectopic pregnancy and chronic pelvic pain. The International Union against Sexually Transmitted Infections (IUSTI) and the US Centers for Disease Control and Prevention (CDC) have issued treatment recommendations for the management of PID. The purpose of this review is to summarise the available evidence for the use of IUSTI- and CDC-recommended antibiotic therapies for PID.

Objective: The present study examined the effects of intraportal infusion of L-arginine on ischemia/reperfusion injury (I/RI) in pig livers, by observing changes in the liver function, liver cell morphology, and changes in the mitochondrial ultrastructure.

Background: The involvement of the nitric oxide (NO) pathway in the reperfusion-ischemic phenomenon is complex and not fully understood. Likewise, little is known about the possible benefit of intraportal infusion of L-arginine (substrate for the NO synthesis) on liver I/RI.
