Increased levels of circulating cell-free double-stranded nucleic acids in the plasma of glioblastoma patients.

Circulating cell-free nucleic acids are considered a promising source of biomarkers for diseases and cancer. Liquid biopsy biomarkers for brain tumours represent a major, still unmet, clinical need. In plasma, nucleic acids can be free or be associated with extracellular vesicles (EVs).

Phenotypic Variability in Acquired and Idiopathic Dystonia.

Background: To date, a few studies have systematically investigated differences in the clinical spectrum between acquired and idiopathic dystonias.

Objectives: To compare demographic data and clinical features in patients with adult-onset acquired and idiopathic dystonias.

Methods: Patients were identified from among those included in the Italian Dystonia Registry, a multicenter Italian dataset of patients with adult-onset dystonia.

Levodopa Equivalent Dose of Safinamide: A Multicenter, Longitudinal, Case-Control Study.

Background: Effects of dopaminergic medications used to treat Parkinson's disease (PD) may be compared with each other by using conversion factors, calculated as Levodopa equivalent dose (LED). However, current LED proposals on MAO-B inhibitors (iMAO-B) safinamide and rasagiline are still based on empirical approaches.

Objectives: To estimate LED of safinamide 50 and 100 mg.

The social and professional image of the nurse: results of a survey during the Covid-19 pandemic.

Introduction: Although nursing today is an intellectual profession to all intents and purposes, thesocial and professional image gap has not yet been bridged. Also, in the rest of the world, the social image of the nurse suffers from some stereotypes, not only perpetuated by a wrong knowledge on the part of the population but also fostered by the mass media (commentary, cinema, television series).

Objective: To investigate the perception of students at the University of Piemonte Orientale about the nursing profession.

Combining three-dimensional fluoroscopy guide system with single-use bronchoscopes for diagnosis of peripheral lesions: First two cases.

Pulmonary Peripheral Lesions (PPLs) diagnosis is usually performed using a guidance system in combination with bronchoscopes and diagnostic tools. We report two cases of PPLs sampling procedures combining the use of the single-use bronchoscope Ambu aScope 5 Broncho and CIOS 3D Spin Mobile (Siemens Healthineers) fluoroscopy system. A 69-year-old-female was found to have a lesion located in right B6 segment and a 73-year-old-male with a mass in the upper right lobe.

Radiotherapy in COVID-19 patient affected by multiple myeloma: a case report.

In COVID-19 pandemic, cancer patients may be vulnerable for their immunological status and need of immunosuppressive anti-neoplastic treatments. Choosing the best treatment option in COVID-19 positive cancer patients is still a challenging issue. We report the case of a 62-year-old woman diagnosed with multiple myeloma and affected by COVID-19.

Medical simulation in pharmacology learning and retention: A comparison study with traditional teaching in undergraduate medical students.

The purpose of the study was to determine whether low-high fidelity medical simulation improves learning and long-lasting retention of pharmacology knowledge, compared to lecture alone, in undergraduate medical students. Ninety students, before a 45-minute lecture, were randomized into three groups - sham (S), low (LF), and high fidelity (HF) simulation - to participate in an interactive simulation session. To evaluate immediate and long-lasting retention, a 20-item structured questionnaire on inotropic agents was administered to 90 students before and after a 45-minute lecture, after simulation, and 3 months later.

Paraganglioma of the head and neck region, treated with radiation therapy, a Rare Cancer Network study.

Background: Paraganglioma of the head and neck (HNPGL) are rare often benign tumors. Surgery and radiation therapy (RT) are the main treatment choices. We present an analysis of outcome and toxicity after RT from 13 institutions of the Rare Cancer Network.

Non-covalently crosslinked chitosan nanofibrous mats prepared by electrospinning as substrates for soft tissue regeneration.

Chitosan (CS) membranes obtained by electrospinning are potentially ideal substrates for soft tissue engineering as they combine the excellent biological properties of CS with the extracellular matrix (ECM)-like structure of nanofibrous mats. However, the high amount of acid solvents required to spun CS solutions interferes with the biocompatibility of CS fibres. To overcome this limitation, novel CS based solutions were investigated in this work.

Effects of Pin1 Loss in Hdh(Q111) Knock-in Mice.

Huntington's disease (HD) is a fatal, dominantly inherited, neurodegenerative disorder due to a pathological expansion of the CAG repeat in the coding region of the HTT gene. In the quest for understanding the molecular basis of neurodegeneration, we have previously demonstrated that the prolyl isomerase Pin1 plays a crucial role in mediating p53-dependent apoptosis triggered by mutant huntingtin (mHtt) in vitro. To assess the effects of the lack of Pin1 in vivo, we have bred Pin1 knock-out mice with Hdh(Q111) knock-in mice, a genetically precise model of HD.

The prion protein constitutively controls neuronal store-operated Ca(2+) entry through Fyn kinase.

The prion protein (PrP(C)) is a cell surface glycoprotein mainly expressed in neurons, whose misfolded isoforms generate the prion responsible for incurable neurodegenerative disorders. Whereas PrP(C) involvement in prion propagation is well established, PrP(C) physiological function is still enigmatic despite suggestions that it could act in cell signal transduction by modulating phosphorylation cascades and Ca(2+) homeostasis. Because PrP(C) binds neurotoxic protein aggregates with high-affinity, it has also been proposed that PrP(C) acts as receptor for amyloid-β (Aβ) oligomers associated with Alzheimer's disease (AD), and that PrP(C)-Aβ binding mediates AD-related synaptic dysfunctions following activation of the tyrosine kinase Fyn.
