Topology of Functional Connectivity and Hub Dynamics in the Beta Band As Temporal Prior for Natural Vision in the Human Brain.

Networks hubs represent points of convergence for the integration of information across many different nodes and systems. Although a great deal is known on the topology of hub regions in the human brain, little is known about their temporal dynamics. Here, we examine the static and dynamic centrality of hub regions when measured in the absence of a task (rest) or during the observation of natural or synthetic visual stimuli.

Epigenetics and MicroRNAs in Cancer.

The ability to reprogram the transcriptional circuitry by remodeling the three-dimensional structure of the genome is exploited by cancer cells to promote tumorigenesis. This reprogramming occurs because of hereditable chromatin chemical modifications and the consequent formation of RNA-protein-DNA complexes that represent the principal actors of the epigenetic phenomena. In this regard, the deregulation of a transcribed non-coding RNA may be both cause and consequence of a cancer-related epigenetic alteration.

CORRELATION BETWEEN OUTER RETINAL THICKENING AND RETINAL FUNCTION IMPAIRMENT IN PATIENTS WITH IDIOPATHIC EPIRETINAL MEMBRANES.

Aim: To assess to what extent patient-related factors influence decisions to switch from a VKA to a NOAC.

Methods: The PREFER in AF Registry collected data at baseline in 2012 - at the beginning of NOAC prescriptions - and at 1-year follow-up, in 6412 patients in seven Western European countries.

Protective Effects Induced by Microwave-Assisted Aqueous Harpagophytum Extract on Rat Cortex Synaptosomes Challenged with Amyloid β-Peptide.

Harpagophytum procumbens is a plant species that displays anti-inflammatory properties in multiple tissues. The iridoid glycosides arpagoside, harpagide, and procumbide appear to be the most therapeutically important constituents. In addition, harpagoside treatment exerted neuroprotective effects both in vitro and in vivo.

Aspirin and the Primary Prevention of Cardiovascular Diseases: An Approach Based on Individualized, Integrated Estimation of Risk.

While the use of aspirin in the secondary prevention of cardiovascular (CVD) is well established, aspirin in primary prevention is not systematically recommended because the absolute CV event reduction is similar to the absolute excess in major bleedings. Recently, emerging evidence suggests the possibility that the assumption of aspirin, may also be effective in the prevention of cancer. By adding to the CV prevention benefits the potential beneficial effect of aspirin in reducing the incidence of mortality and cancer could tip the balance between risks and benefits of aspirin therapy in the primary prevention in favour of the latter and broaden the indication for treatment with in populations at average risk.

Relationship between peripheral insertion site and catheter-related phlebitis in adult hospitalized patients: a systematic review.

Aim: To explore the relationship between the anatomical site of peripheral venous catheterization and risk of catheter-related phlebitis.

Background: Peripheral venous catheterization is frequently associated with phlebitis. Recent guidelines, recommend the use of an upper-extremity site for catheter insertion but no univocal consensus exists on the anatomical site with lower risk of phlebitis.

Optimization of Aqueous Extraction and Biological Activity of Harpagophytum procumbens Root on Ex Vivo Rat Colon Inflammatory Model.

Harpagophytum procumbens has a long story of use for the treatment of inflammatory diseases. Considering both the antiinflammatory effects of H. procumbens in multiple tissues and the stability of harpagoside in artificial intestinal fluid, the aim of the present study was to explore the possible protective role of a microwave-assisted aqueous Harpagophytum extract (1-1000 μg/mL) on mouse myoblast C2C12 and human colorectal adenocarcinoma HCT116 cell lines, and isolated rat colon specimens challenged with lipopolysaccharide (LPS), a validated ex vivo model of acute ulcerative colitis.

Fat mass and obesity-associated gene (FTO) is associated to eating disorders susceptibility and moderates the expression of psychopathological traits.

Eating Disorders (EDs) show a multifactorial etiopathogenesis including environmental, psychological and biological factors. In the present study, we propose a model of interactions between genetic vulnerability-represented by Fat Mass and Obesity-Associated (FTO) gene-and stable psychopathological traits, such as bodily disorders and emotion dysregulation for EDs patients. The distribution of a polymorphism of the FTO (rs9939609 T>A) was evaluated in a series of 250 EDs patients and in a group of 119 healthy control subjects.

A new case of "de novo" BRCA1 mutation in a patient with early-onset breast cancer.

Most of the de novo BRCA1/2 mutations have been identified in patients with early-onset breast cancer and without family history of the disease. The identification of these alterations could play a prominent role in the prevention and treatment strategies and may influence clinical management of patients.

Edoxaban in Atrial Fibrillation and Venous Thromboembolism-Ten Key Questions and Answers: A Practical Guide.

Edoxaban is the fourth non-vitamin K antagonist oral anticoagulant now available for clinical use in the prevention of stroke/systemic embolism in atrial fibrillation (AF) and in the treatment of venous thromboembolism (VTE), after the completion of large-scale randomized comparative clinical trials with the vitamin K antagonist warfarin. Edoxaban has some peculiar pharmacological properties and outcome data. Here a group of experts in AF and VTE answers a set of questions on its practical use, trying to define the profile of patients that would be most appropriate for its use.

Adaptation to Complex Pictures: Exposure to Emotional Valence Induces Assimilative Aftereffects.

Aftereffects have been documented for a variety of perceptual categories spanning from body gender to facial emotion, thus becoming an important tool in the study of high-level vision and its neural bases. We examined whether the perceived valence of a complex scene is subject to aftereffects, by observing the participants' evaluation of the valence of a test picture preceded by a different picture. For this study, we employed an adaptation paradigm with positive and negative images used as adapters, and positive, negative, and neutral images used as tests.

Comparison between CaGene 5.1 and 6.0 for BRCA1/2 mutation prediction: a retrospective study of 150 BRCA1/2 genetic tests in 517 families with breast/ovarian cancer.

During the past years, several empirical and statistical models have been developed to discriminate between carriers and non-carriers of germline BRCA1/BRCA2 (breast cancer 1, early onset/breast cancer 2, early onset) mutations in families with hereditary breast or ovarian cancer. Among these, the BRCAPRO or CaGene model is commonly used during genetic counseling, and plays a central role in the identification of potential carriers of BRCA1/2 mutations. We compared performance and clinical applicability of BRCAPRO version 5.

Anticancer therapy-induced vascular toxicity: VEGF inhibition and beyond.

Cardiotoxicity induced by chemotherapeutic agents and radiotherapy is a growing problem. In recent years, an increasing number of new drugs with targeted action have been designed. These molecules, such as monoclonal antibodies and tyrosine kinase inhibitors, can cause different type of toxicities compared to traditional chemotherapy.

Heart failure due to right ventricular apical pacing: the importance of flow patterns.

In patients receiving permanent cardiac electrical stimulation, a high burden of apical right ventricular pacing is associated with an increased incidence of heart failure. Despite the large body of electrocardiographic, echocardiographic, and pathological data, mechanisms underlying this serious complication are not fully understood. Moreover, the empirical use of alternative right ventricular pacing sites, both in the experimental and in the clinical setting, has not provided better results in terms of clinical outcome.
