Recent results on heavy-ion induced reactions of interest for neutrinoless double beta decay at INFN-LNS

2019

Abstract The NUMEN project aims at accessing experimentally driven information on Nuclear Matrix Elements (NME) involved in the half-life of the neutrinoless double beta decay (0νββ). In this view measurements of Heavy Ion (HI) induced Double Charge Exchange (DCE) reaction cross sections are performed with high-accuracy. In particular, the (18O,18Ne) and (20Ne,20O) reactions are used as tools for β+β+ and β-β- decays, respectively. In the experiments, performed at INFN - Laboratory Nazionali del Sud (LNS) in Catania, the beams are accelerated by the Superconducting Cyclotron (CS) and the reaction ejectiles are detected the MAGNEX magnetic spectrometer. The measured cross sections are challe…

Recent results on Heavy-Ion induced reactions of interest for 0νββ decay

2019

An updated overview of recent results on Heavy-Ion induced reactions of interest for neutrinoless double beta decay is reported in the framework of the NUMEN project. The NUMEN idea is to study heavy-ion induced Double Charge Exchange (DCE) reactions with the aim to get information on the nuclear matrix elements for neutrinoless double beta (0νββ) decay. Moreover, to infer the neutrino average masses from the possible measurement of the half- life of 0νββ decay, the knowledge of the nuclear matrix elements is a crucial aspect. Uma visão geral atualizada dos resultados recentes sobre reações induzidas por íons pesados ​​de interesse para o decaimento beta duplo sem neutrinos é relatada na es…

INDICATORI PER LA VALUTAZIONE DELL'APPROPRIATEZZA DEL PERCORSO NASCITA

2015

Introduzione:La gravidanza, il parto ed il puerperio sono eventi fisiologici che possono talvolta complicarsi in modo non prevedibile e con conseguenze gravi per la donna, per il nascituro e per il neonato. Gli standard nazionali prevedono la razionalizzazione/riduzione progressiva dei punti nascita con numero di parti inferiore a 1000/anno, e l'abbinamento per pari complessità di attività delle UU.OO. ostetrico-ginecologiche con quelle neonatologiche/pediatriche, riconducendo a due i precedenti tre livelli assistenziali. I punti nascita privi di una copertura di guardia medico-ostetrica, anestesiologica e medico pediatrica attiva h 24, o di risorse umane e di attrezzature adeguate non dovr…

An Unexplained Congenital Disorder of Glycosylation-II in a Child with Neurohepatic Involvement, Hypercholesterolemia and Hypoceruloplasminemia

2017

We report on a 12-year-old adopted boy with psychomotor disability, absence seizures, and normal brain MRI. He showed increased (but initially, at 5 months, normal) serum cholesterol, increased alkaline phosphatases, transiently increased transaminases and hypoceruloplasminemia with normal serum and urinary copper. Blood levels of immunoglobulins, haptoglobin, antithrombin, and factor XI were normal. A type 2 serum transferrin isoelectrofocusing and hypoglycosylation of apoCIII pointed to a combined N- and O-glycosylation defect. Neither CDG panel analysis with 79 CDG-related genes, nor whole exome sequencing revealed the cause of this CDG. Whole genome sequencing was not performed since th…

Neonicotinoids from coated seeds toxic for honeydew-feeding biological control agents

2021

Seed coating (‘seed treatment’) is the leading delivery method of neonicotinoid insecticides in major crops such as soybean, wheat, cotton and maize. However, this prophylactic use of neonicotinoids is widely discussed from the standpoint of environmental costs. Growing soybean plants from neonicotinoid-coated seeds in field, we demonstrate that soybean aphids (Aphis glycines) survived the treatment, and excreted honeydew containing neonicotinoids. Biochemical analyses demonstrated that honeydew excreted by the soybean aphid contained substantial concentrations of neonicotinoids even one month after sowing of the crop. Consuming this honeydew reduced the longevity of two biological control …

Highly Efficient Removal of Neonicotinoid Insecticides by Thioether-Based (Multivariate) Metal–Organic Frameworks

2021

Circumventing the impact of agrochemicals on aquatic environments has become a necessity for health and ecological reasons. Herein, we report the use of a family of five eco-friendly water-stable isoreticular metal-organic frameworks (MOFs), prepared from amino acids, as adsorbents for the removal of neonicotinoid insecticides (thiamethoxam, clothianidin, imidacloprid, acetamiprid, and thiacloprid) from water. Among them, the three MOFs containing thioether-based residues show remarkable removal efficiency. In particular, the novel multivariate MOF {SrIICuII6[(S,S)-methox]1.5[(S,S)-Mecysmox]1.50(OH)2(H2O)}·36H2O (5), featuring narrow functional channels decorated with both -CH2SCH3 and -CH2…

Les accidents vasculaires cérébraux du nouveau-né et de l’enfant

2009

The clinical presentation, risk factors, causes, vital or functional prognosis, and acute management options for stroke occurring in neonates and children are specific, differing from those observed in young adults. Compared with the adult population, less is known about the epidemiology of stroke in the under-18 population where the disease could become more frequent because of advances in both neonatal resuscitation techniques for cerebral disorders and neuroimaging techniques enabling the diagnosis of small lesions. Clinical features are often delayed, especially in neonates, and unlike epilepsy or dystonia of the affected limb, which are frequent complications, aphasia is rather rare. T…

Acute appendicitis in a patient with situs viscerum inversus totalis: Role of laparoscopic approach. A case report and brief literature review

2020

Highlights • Abdominal pain due to acute appendicitis in one of the most causes of access to Emergency Room requiring surgical consult and treatment. • The occurrence of anatomical anomalies should be considered especially when clinical and imaging features are misleading. In these cases laparoscopic surgery can be a safe tool in order to confirm uncertain diagnosis. • We report a case of acute appendicitis in a 23-year-old Caucasian men with situs viscerum inversus detected on radiological investigation. • Laparoscopic approach was used to confirm the diagnosis and to perform appendectomy. Trocars placement was tailored for this peculiar case. • Situs viscerum inversus and midgut malrotati…

Evidence against linkage of schizophrenia to chromosome 5q11-q13 markers in systematically ascertained families.

1992

Ten pedigrees systematically ascertained in Germany were tested for linkage to chromosome 5q11-q13. In order to replicate the previous report by Sherrington et al (1988), families with a bipolar family member were omitted from the lod score calculations, all diagnoses were based upon Research Diagnostic Criteria, and four different models of the affection status were calculated, including the model for which Sherrington et al calculated the highest lod scores. None of the families investigated showed a positive lod score. Using multipoint linkage analyses, we were able to exclude the region for which a positive linkage has been reported.
