PURPOSE: Meningiomas account for one third of primary intracranial tumors, nevertheless information on meningioma cell lines and in vivo models is scant. Although radiotherapy is one of the most relevant therapeutic options for the treatment patients with meningioma, radiobiological research to understand tumor responses to this treatment is far from being thoroughly understood. The aim of this report is to provide a comprehensive picture of the current literature on this field, so as to foster s research in this regard...

The adsorption behavior of neodymium (Nd3+) and yttrium (Y3+) cations on synthetic FAU zeolite 13X in its sodium form (Na13X) has been investigated by means of an approach based on both macroscopic (namely, adsorption isotherm determination and thermal analysis) and microscopic measurements (including solid-state NMR spectroscopy and X-ray powder diffraction). The multidisciplinary study has revealed some unexpected features. Firstly, adsorption constants of cations are not correlated to their ionic radii (or hydration enthalpy)...

Chronic Myeloid Leukemia (CML) is a stem cell disease sustained by a rare population of quiescent cells which are to some extent resistant to tyrosine kinase inhibitors (TKIs). BCR-ABL oncogene activates multiple cross-talking signal transduction pathways (STP), such as RAS/MEK/ERK, PI3K/Akt, Wnt and STAT5, contributing to abnormal proliferation of clonal cells. From this perspective, the aim of this study was to analyze the expression and activation profile of STP involved in the mechanisms of cell proliferation/quiescence and survival of the progenitor CD34+ cells from chronic phase (CP) CML...

BACKGROUND: Vaccines are very effective medical tools for disease prevention and life span increase. Controversies have raised concern about their safety, from autism to polio vaccine contamination with simian virus 40 (SV-40). Hysteria surrounding vaccine-associated risks has resulted in a declining number of vaccinations in developed countries. Outbreaks of vaccine-preventable diseases (e.g. measles) have occurred in Europe and North America, causing also some causalities. OBJECTIVES: In this review, data on safety and efficacy of vaccines are discussed, showing that the benefits of vaccines far outweigh the risks and that it is important to comply with vaccination protocols, to avoid spreading of severe, preventable diseases...

Prepartum supplementation with conjugated linoleic acid (CLA) may influence lipolysis and hyperketonemia in dairy cows. The objective of this study was to examine the effect of prepartum CLA supplementation on lactation performance and serum fatty acids (FA) and β-hydroxybutyrate (BHB) in early lactation dairy cows, and secondarily on reproductive performance. Multiparous cows were enrolled in the study at 18 days prior to expected calving date, and randomly assigned 100 g/day of Lutrell Pure (BASF, Ludwigshafen, Germany; 75% FA), providing 10 g/day of each CLA isomer (trans-10 cis-12 and cis-9 trans-11 CLA) or equivalent amount of rumen inert fatty acids as control (78 g/day of Energy Booster 100; Milk Specialties Global, Eden Prairie, MN)...

BACKGROUND: Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration is a well-established first-line minimally invasive modality for mediastinal lymph node sampling. Although results are excellent overall, the technique underperforms in certain situations. We aimed to describe our results using a new 19-G EBUS-guided transbronchial needle aspiration device to determine safety and feasibility of this approach. METHODS: We completed a retrospective chart review of all cases performed to the time of data analysis at each of 3 study sites...

No evidence from any longitudinal study design has been reported to date with regard to patient safety (PS) incidents witnessed by nursing students during their training. Therefore, with the aim of closing this gap in available knowledge, a longitudinal study was performed from 2012 to 2015 by involving all nursing students (n = 145) enrolled in two Italian nursing programs. At the end of each academic year, students were invited to report in writing all PS incidents witnessed during their clinical learning experience; the number of days each student spent in their clinical setting was also collected from administrative records...

Aims: Comparison of outcomes between subcutaneous and transvenous implantable cardioverter-defibrillator (S-ICD and TV-ICD) therapy is hampered by varying patient characteristics and complication definitions. The aim of this analysis is to compare clinical outcomes of S-ICD and TV-ICD therapy in a matched cohort. Methods and results: Patients implanted with de novo implantable cardioverter-defibrillators without need for pacing were selected from two studies: SIMPLE (n = 1091 single and n = 553 dual chamber TV-ICDs) and EFFORTLESS (n = 798 S-ICDs)...

AIM: Estimation of specific IgE is essential for the prevention of allergy progression. Quantitative immuno-PCR (qiPCR) can increase the sensitivity of IgE detection. We aimed to develop qiPCR and compare it to the conventional ELISA in identification of IgE to Alt a 1 and Fel d 1 allergens. RESULTS: Single stranded 60-mer DNA conjugated to streptavidin was used to detect antigen-IgE-biotin complex by qiPCR. In semi-logarithmic scale qiPCR data were linear in a full range of serum dilutions resulting in three- to ten-times higher sensitivity of qiPCR in comparison with ELISA in IgE estimation in low titer sera...

The A2A adenosine receptor (A2A R) is widely distributed on different cellular types in the brain, where it exerts a broad spectrum of pathophysiological functions, and for which a role in different neurodegenerative diseases has been hypothesized or demonstrated. To investigate the role of neuronal A2A Rs in neurodegeneration, we evaluated in vitro and in vivo the effect of the neurotoxin 3-nitropropionic acid (3-NP) in a transgenic rat strain overexpressing A2A Rs under the control of the neural-specific enolase promoter (NSEA2A rats)...

Increasing evidence focuses on the endocannabinoid system as a relevant player in the induction of aberrant synaptic plasticity and related addictive phenotype following chronic excessive alcohol drinking. Besides, the endocannabinoid system is implicated in the pathogenesis of alcoholic liver disease. Interestingly, whereas the involvement of CB1 cannabinoid receptors in alcohol rewarding properties is established, the central and peripheral action of CB2 cannabinoid signalling is still to be elucidated. This review aims at giving the input to deepen knowledge on the role of the endocannabinoid system, highlighting the advancing evidence that suggests that CB1 and CB2 receptors may play opposite roles in the regulation of both the reinforcing properties of alcohol in the brain and the mechanisms responsible for cell injury and inflammation in the hepatic tissue...

Intrafibral vacuoles are the morphological hallmark in a wide variety of human skeletal muscle disorders with different etiology. In most cases, differential diagnosis is feasible with a routine histochemical work up of muscle biopsy. Ultrastructural analysis is an important confirmatory tool, but it is not widely available. Immunohistochemical stainings for p62, LAMP2 and LC3 are commonly available as tissutal marker for autophagy. We compared the immunohistochemical patterns for autophagic markers p62, LC3 and LAMP2 with routine histochemical markers in 39 biopsies from patients with definite diagnoses of glycogen storage disease type 2 (LOPD or Pompe disease, PD), sporadic inclusion body myositis (sIBM), oculo-pharyngeal muscular dystrophy (OPMD) and necrotizing myopathy (NM)...

The excessive production of type I IFNs is a hallmark and a main pathogenic mechanism of many autoimmune diseases, including systemic lupus erythematosus (SLE). In these pathologies, the sustained secretion of type I IFNs is dependent on the improper activation of plasmacytoid DCs (pDCs) by self-nucleic acids. However, the nature and origin of pDC-activating self-nucleic acids is still incompletely characterized. Here, we report that exosomes isolated from the plasma of SLE patients can activate the secretion of IFN-α by human blood pDCs in vitro...

AIMS: Use of complementary and alternative medicines (CAMs) during breastfeeding is commonly increasing, mainly due to their presumed higher safety compared to conventional medications. Indeed, CAMs can cause serious adverse effects, and high-quality evidence supporting their use during lactation is limited. In Italy, specific investigations on the attitude of lactating women towards CAMs are lacking. The Herbal supplements in Breastfeeding InvesTigation (HaBIT) aimed to explore the attitudes and knowledge on CAMs among lactating women...

Despite the fact that human body odors can transfer anxiety-related signals, the impact of such signals in real-life situations is scant. In this study, the effects of anxiety chemosignals on the performance of dental students operating on simulation units, wearing t-shirts imbued with human sweat and masked with eugenol were tested. Twenty-four 4th year dental students (17F) donated their body odors in two sessions (Anxiety and Rest). Twenty-four normosmic, sex- and age-matched test subjects who were3rd year dental students performed three dental procedures while smelling masked anxiety body odors, masked rest body odors or masker alone...

The presence of H2 S pathway in skeletal muscle (SKM) has been recently established. SKM expresses the three constitutive H2 S generating enzymes in animals and humans and it actively produces H2 S. The main recognized molecular targets of H2 S, i.e. potassium channels and phosphodiesterases, have been evaluated in SKM physiology in order to hypothesize a role for H2 S signaling. SKM dysfunctions, including muscular dystrophy and malignant hyperthermia, have been also evaluated as conditions in which H2 S-pathway and the trans-sulfuration pathway have been suggested to be involved...

AIM: The EGFR inhibitors represent the first-line treatment of non-small-cell lung cancer. However, the emergence of resistance urgently requires the development of new inhibitors targeting drug-resistant mutants. METHODOLOGY: A recently released structure of an EGFR kinase domain in complex with an allosteric inhibitor and a mutant protein model derived from it were used to set up a low-cost high-throughput docking protocol for the fast identification of EGFR allosteric inhibitors...
