OBJECTIVES: The attention-deficit/hyperactivity disorder (ADHD) compromises the quality of life of individuals including adaptation to the social environment. ADHD aetiology includes perinatal conditions such as hypoxic-ischaemic events; preclinical studies have demonstrated attentional deficits and impulsive-hyperactive outcomes after neonatal hypoxic and/or ischaemic intervention, but data are missing to understand this relationship. Thus, the aim of this study was to evaluate executive function (EF) and impulsivity, and tissue integrity and dopaminergic function in the prefrontal cortex (PFC) of rats submitted to hypoxia-ischaemia (HI)...

BACKGROUND: In 2015, Italy was the second most common point of entry for asylum seekers into Europe after Greece. The vast majority embarked from war-torn Libya; 80,000 people claimed asylum that year. Their medical conditions were assessed on arrival but their mental health needs were not addressed in any way, despite the likelihood of serious trauma before and during migration. Médecins sans Frontières (MSF), in agreement with the Italian Ministry of Health, provided mental health (MH) assessment and care for recently-landed asylum seekers in Sicily...

Chemical Biology employs chemical synthesis, analytical chemistry and other tools to study biological systems. Recent advances in both molecular biology such as next generation sequencing (NGS) have led to unprecedented insights towards the evolution of organisms' biochemical repertoires. Because of the specific data sharing culture in Genomics, genomes from all kingdoms of life become readily available for further analysis by other researchers. While the genome expresses the potential of an organism to adapt to external influences, the Metabolome presents a molecular phenotype that allows us to asses the external influences under which an organism exists and develops in a dynamic way...

Von Willebrand Factor (VWF) has a central role in primary hemostasis. Its biological activity is related to the size of VWF multimers, spontaneously binding to platelets and inducing circulating microthrombi formation. This process is down-regulated by the VWF cleaving protease ADAMTS13 (A Disintegrin and Metalloprotease with ThromboSpondin motif). To date, information regarding the levels of ADAMTS13 in neonates and preterm infants is scarce. Our aim was to study ADAMTS13, VWF antigen (Ag) and Ristocetin cofactor (RiCof) activity in neonates and evaluate potential correlations with perinatal complications...

Restoration of acid sulfate soil (ASS) wetlands by freshwater re-flooding can lead to the reformation of various Fe(II) and reduced inorganic sulfur (RIS) species in surface soil layers. However, in many locations, wetland water levels undergo large seasonal fluctuations that drive extreme redox oscillations. Newly formed RIS species [e.g. greigite, mackinawite, nano-pyrite and S(0)] and Fe(II) are vulnerable to rapid oxidation during dry periods and may generate substantial acidity. Rainfall following a dry period may then mobilise acidity and metal cations in surface waters prior to eventual recovery in pH by re-establishment of reducing conditions...

BACKGROUND: Though the presence of platelets-derived microparticles (MPs) have previously been described in heparin-induced thrombocytopenia (HIT), the mechanism of thrombosis in HIT remains poorly understood. We aimed to asses the presence and origin of MPs in patients with HIT and their possible contribution to HIT with thrombosis (HITT). METHODS: Forty-five patients with HIT and 45 matched hospitalized patients with not confirmed HIT (HIT-negative) were enrolled...

BACKGROUND & AIMS: Most patients with a hepatocellular carcinoma (HCC) have an underlying chronic liver inflammation, which causes a continuous damage leading to liver cirrhosis and eventually HCC. However, only a minority of cirrhotic patients develop HCC. To asses a possible differential impact of liver inflammation in patients developing HCC versus patients remaining tumor-free we designed a longitudinal study and analyzed liver tissue of the same patient (n = 33) at two points in time: once when no HCC was present and once, several years later, when a HCC was present...

PURPOSE: The use of radiation as a treatment modality for skin cancer has increased significantly over the last decade with standardized applicators. Utilizing 3D printing, the ability to make applicators specifically designed for each patient's anatomy has become economically feasible. With this in mind it was the aim of this study to determine the dosimetric accuracy of a 3-D printed HDR brachytherapy applicator for the skin. METHODS: A CT reference image was used to generate a custom applicator based on an anthropomorphic head and neck phantom...

Acute splenic sequestration in children with sickle cell disease - an overview Acute splenic sequestration (ASS) is a life-threatening complication of sickle cell disease (SCD). The condition is important to recognize due to the fact that it can occur with previously unknown disease. ASS is one of the most common causes of death in children with SCD and is the result of blood suddenly getting congested in the spleen, resulting in splenomegaly, acute anemia, and hypovolemic shock. Timely and appropriate treatment is essential in preventing death...

Fecal calprotectin (FC) is used to asses the presence of intestinal inflammation also in patients with Cystic Fibrosis (CF) and recent studies showed a correlation between bowel and lung disease in these patients. The aim of this study was to analyze the levels of FC in CF and correlate them with different phenotypes of disease. We enrolled a cohort of 54 CF patients and 50 healthy controls. In these patients, calprotectin has been assayed on a stools sample using an ELISA kit. In all patients we analyzed, FC levels were elevated above the cut-off value and significantly higher than in healthy controls...

The epidemiological importance of Chagas disease vectors largely depends on their spreading ability and adaptation to domestic habitats. Triatoma patagonica is a secondary vector of Chagas disease endemic of Argentina, and it has been found colonizing domiciles and most commonly peridomiciliary structures in several Argentine provinces and morphological variation along its distribution range have been described. To asses if population differentiation represents geographic variants or true biological species, multiple genetic and phenotypic approaches and laboratory cross-breeding were performed in T...

All-solid-state Li-ion batteries (ASS-LIBs) are expected to be the next-generation battery, however, their large interfacial resistance hinders their widespread application. To understand and resolve the possible causes of this resistance, we examined mutual diffusion properties of the cation elements at LiCoO2 (LCO) cathode/β-Li3PS4 (LPS) solid electrolyte interface as a representative system as well as the effect of a LiNbO3 buffer layer by first-principles calculations. Evaluating energies of exchanging ions between the cathode and the electrolyte, we found that the mixing of Co and P is energetically preferable to the unmixed states at the LCO/LPS interface...

An important characteristic of the auditory system is the capacity to analyze complex sounds and make decisions on the source of the constituent parts of these sounds. Blind individuals compensate for the lack of visual information by an increase input from other sensory modalities, including increased auditory information. The purpose of the current study was to compare the fission boundary (FB) threshold of sighted and early blind individuals through spectral aspects using a psychoacoustic auditory stream segregation (ASS) test...

In this study we investigate, both numerically and experimentally, the interplay between the intrinsic Darrieus-Landau (DL) or hydrodynamic instability of a premixed flame and the moderately turbulent flow field in which the flame propagates. The objective is threefold: to establish, unambiguously, through a suitably defined marker, the presence or absence of DL-induced effects on the turbulent flame, to quantify the DL effects on the flame propagation and morphology and, finally, to asses whether such effects are mitigated or suppressed as the turbulence intensity is increased...

INTRODUCTION: End-stage renal disease (ESRD) is associated with increased infectious susceptibility and with reduced vaccine responses consistent with compromised humoral immunity. Whether the compromised humoral immunity is due to reduced antibody diversity (reduced somatic hypermutation [SHM]) or altered germinal center (GC) dynamics is not known. The GC-derived chemokine CXCL13 as well as peripheral T follicular helper cells (pTFH) reflect GC dynamics, but have, similar to SHM, never been characterized in relation to ESRD...

A woman aged 61 years presented to the emergency room with a 1-week history of dyspnoea on exertion and dry cough. X-ray of the chest showed diffuse interstitial opacities and was started on antibiotics and furosemide, and despite these measures, patient's respiratory status worsened, prompting endotracheal intubation. CT of the chest showed diffuse bilateral ground glass opacities and underwent bronchoscope with trans-bronchial biopsy that showed chronic bronchitis. Pt was empirically started on intravenous steroids due to concerns for interstitial lung disease (ILD)...
