Nitrogen-Containing Aromatic Compound from the Culture Medium of Penicillium chrysogenum THOM

Investigation of the culture medium of Penicillium chrysogenum THOM (contaminant of two strains of Ceratocystis fimbriata) led to the isolation of the sesquiterpene PR toxin (1) and 2-[(2-hydroxypropionyl)amino]benzamide (2) which have never been isolated as a natural product

Qualitative analysis of determinants of measles, mumps, rubella vaccine uptake in European parents

Background Parental concerns about measles, mumps and rubella (MMR) vaccination negatively influence decision to vaccinate their children, this leading to the recently reported vaccine coverage drop in Europe. The ESCULAPIO project, funded by the Italian National Centre for Disease Prevention and Control of the Ministry of Health (CCM), is investigating the main factors underlying decisions on vaccinations, in order to implement targeted campaigns and plan effective strategies. Methods A systematic literature review was carried out on studies describing the determinants underlying MMR vaccination uptake in European parents. Results A total of 45 studies were included in the analysis. The most common factors related with MMR vaccine uptake were knowledge, beliefs, perceptions on vaccines and diseases, reported in 44,4% of the articles. Parents showed doubts on vaccine efficacy, safety, side effects, while in other studies positive beliefs and perceptions were reported. Attitudes/ behaviours were often determinants of the uptake as well as demographic factors (40%). While higher no. of children in the household, lower income, temporary or lacking employment, and non-regular marital status were generally a barrier for vaccination, education level and house tenure were contradictory. Information source/advice and influence or trust of other people, institutions, media were often reported (31,1% and 17,8% respectively), but a clear direction was not showed. Conclusions These preliminary findings showed that communication strategies should provide parents with clear messages on vaccines and preventable infectious diseases, in order to build right knowledge and create correct beliefs and behaviours. Communication should be addressed mainly to more disadvantaged, larger and non-regular families. A quantitative analysis is been currently carrying out and will provide more information on the direction of the effect of the different factor

Growth of NiO thin films in the presence of water vapor: insights from experiments and theory

NiO-based thin films and nanomaterials are promising candidates for a variety of end-uses, encompassing photo- and electrocatalysts, solar cells, displays, and sensors. This widespread attention has strongly fueled the interest in the fabrication of tailored systems featuring modular chemico-physical properties as a function of the required application. In this study, a single-step chemical vapor deposition (CVD) route for the preparation of pure and fluorine-doped NiO films is presented. Growth experiments were performed under water vapor-containing oxygen atmospheres from a series of Ni(II) β-diketonate–diamine molecular precursors featuring a different fluorination degree of the ligand side chain. A comprehensive experimental and theoretical investigation yielded valuable insights into the growth mechanism, with particular regard to the dependence of the system electronic properties on fluorine doping and content, and to the role exerted by water vapor in the reaction atmosphere. In fact, the interactions of water with the diketonate ligands contribute to weaken Ni–O bonds, favoring precursor activation. The obtainment of F-doped NiO systems from fluorinated derivatives and the simplicity of our process make the adopted strategy a valuable tool to control the system characteristics for a variety of eventual functional applications

A REST-based framework to support non-invasive and early coeliac disease diagnosis

The health sector has traditionally been one of the early adopters of databases, from the most simple Electronic Health Record (formerly Computer-Based Patient Record) systems in use in general practice, hospitals and intensive care units to big data, multidata based systems used to support diagnosis and care decisions. In this paper we present a framework to support non-invasive and early diagnosis of coeliac disease. The proposed framework makes use of well-known technologies and techniques, both hardware and software, put together in a novel way. The main goals of our framework are: (1) providing users with a reliable and fast repository of a large amount of data; (2) to make such repository accessible by means of a suitable API in multiple modes, such as intuitive web-based or mobile visual interfaces; (3) to allow for data processing and analysis, as a basis for decision support systems

FREQUENCY OF HEPATIC LIPIDOSIS IN JUVENILE RAINBOW TROUT (ONCORHYNCHUS MYKISS) IN A FISH FARM IN THE PERUVIAN CENTRAL SIERRA

El objetivo del estudio fue determinar la frecuencia de lipidosis hepática en la trucha arcoíris (Oncorhynchus mykiss) de fase juvenil en base a lesiones anátomohistopatológicas en el hígado. Se trabajó con 58 peces de una piscigranja comercial de la sierra central del Perú. Los peces fueron clasificados como sanos (n=23) y enfermos (n=35) según el oscurecimiento de la piel y erosión de las aletas. Se colectaron muestras de hígado, que se fijaron en formol al 10% y fueron coloreadas con Hematoxilina-eosina. El 70.6% (41/58) de los peces presentó lesiones compatibles con lipidosis hepática, siendo el grado 3 el de mayor presentación (27.6%). Las mayores frecuencias de lipidosis hepática en grados 3 y 4 se observaron en animales sanos.The objective of the study was to determine the frequency of hepatic lipidosis in rainbow trout (Oncorhynchus mykiss) of juvenile phase based on anatomical and histopathological lesions in the liver. The specimens (n=58) were obtained from a commercial fish farm in the central highlands of Peru. The fish were classified as healthy (n=23) and ill (n=35) according to the darkening of the skin and fin erosion. Liver samples were collected, fixed in 10% formalin, and stained with hematoxylin eosin. Results showed that 70.6% (41/58) of the fish had lesions compatible with hepatic lipidosis, where grade 3 had the largest incidence (27.6%). The highest frequency of hepatic lipidosis in grade 3 and 4 was observed in healthy animals

Field-based tests for the assessment of physical fitness in children and adolescents practicing sport: A systematic review within the ESA program

High levels of physical fitness (PF) can positively affect both health and cognitive function, thus monitoring its levels in youth can help increase health and quality of life in adult populations later on. This systematic review aims to identify PF field-based tests used in young European populations practicing sport to find tools that are adequate for the considered target involving a new battery within the Enriched Sport Activities (ESA) project. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed. In the 83 identified articles, the main tests used were: vertical/horizontal jumps (for muscular strength/power); push-ups, running at maximum effort, sit-ups (for muscular strength/endurance); multistage non-intermittent and intermittent tests (for aerobic endurance); sit and reach (for flexibility); sprinting and agility T-tests (for speed and agility, respectively); 10 x 5 m shuttle run (SR) (for both speed and agility). Few studies assessed coordination, reaction time, power, and balance. Although the selected tests are widely used and validated, they do not determine all PF aspects and do not reflect sport-specific features. A final decision was made for the inclusion of the following tests: standing broad jump, seated medicine ball throw, 20 m SR test, 30 m sprint, Illinois test, and a new test, i.e., the crunning test, to assess different skill-related components at once. The use of this combination of tests allows for the assessment of all PF components and can help planning eective training programs and cultivate sporting talent
