Serum miR-96-5P and miR-339-5P Are Potential Biomarkers for Multiple System Atrophy and Parkinson's Disease.

Parkinson's disease (PD) and Multiple System Atrophy (MSA) are progressive neurodegenerative diseases with overlap of symptoms in early stages of disease. No reliable biomarker exists and the diagnosis is mainly based on clinical features. Several studies suggest that miRNAs are involved in PD and MSA pathogenesis.

Serum miR-30c-5p is a potential biomarker for multiple system atrophy.

Multiple system atrophy (MSA) is a neurodegenerative disease that belongs to the α synucleinopathies. Clinically, there is an overlap between MSA and Parkinson's disease (PD), especially at the early disease stage. However, these two pathologies differ in terms of disease progression.

Complex interfaces in "phase-change" contrast agents.

In this paper we report on the study of the interface of hybrid shell droplets encapsulating decafluoropentane (DFP), which exhibit interesting potentialities for ultrasound (US) imaging. The fabrication of the droplets is based on the deposition of a dextran methacrylate layer onto the surface of surfactants. The droplets have been stabilized against coalescence by UV curing, introducing crosslinks in the polymer layer and transforming the shell into an elastomeric membrane with a thickness of about 300 nm with viscoelastic behaviour.

Hyaluronic acid nanohydrogels as a useful tool for BSAO immobilization in the treatment of melanoma cancer cells.

An alternative anticancer therapy based on the use of bovine serum amine oxidase (BSAO), an enzyme that converts polyamines over-expressed in malignant cells, into hydrogen peroxide and aldehyde(s), thus inducing high cytotoxicity in cancer cells, was recently proposed. With the aim of improving the system efficacy by exploiting a nanotechnology approach, BSAO is covalently immobilized onto injectable nanohydrogels (NHs) based on cholesterol-graft-hyaluronic acid (HA-CH), a biocompatible conjugate that spontaneously leads to self-assembled structures in aqueous solutions. In this study, the physicochemical properties of the HA-CH-based NHs and the NHs cytocompatibility are reported.

A general strategy for obtaining biodegradable polymer shelled microbubbles as theranostic devices.

Fabrication of multifunctional ultrasound contrast agents (UCAs) has been recently addressed by several research groups. A versatile strategy for the synthesis of UCA precursors in the form of biodegradable vesicles with a biocompatible crosslinked polymer shell is described. Upon ultrasound irradiation, acoustic droplet vaporization transforms such particles into microbubbles behaving as UCAs.
