Environmental factors influencing the distribution and prevalence of Schistosoma haematobium in school attenders of ILembe and uThungulu Health Distr…

2017

Schistosoma haematobium infection is reported to facilitate the development of urogenital diseases. Its symptoms include haematuria, dysuria and tiredness, and it may cause cognitive decline in children. The prevalence of S. haematobium infection needs to be known in endemic areas and a mass treatment programme against the disease implemented. The aim of this study was to investigate the prevalence and intensity of S. haematobium infection in ILembe and uThungulu health districts, using the major symptom, haematuria, as an indicator. A total of 6 265 urine samples, from 96 rural schools, was collected for analysis using dipsticks. The prevalence of haematuria in the ILembe health district w…

Kielentämisen näkökulmia kuudennen luokan oppilaiden matematiikan sanallisten tehtävien ratkaisuihin

2022

Artikkelissa tarkastellaan kuudennen luokan lopussa oppilaiden tuottamia ratkaisuja kahteen sanalliseen ongelmanratkaisutehtävään. Tutkimuksen toteutti matemaattiseen ajatteluun ja sen kielentämiseen perehtynyt opettaja. Tutkimukseen osallistui 35 kuudennen luokan oppilasta. Tutkimusaineistona olivat oppilaiden kirjalliset ratkaisut kahteen sanalliseen ongelmanratkaisutehtävään. Oppilaat kuvasivat kielentämisen keinoin omaa matemaattista ajatteluaan sekä tehtävien tuottamisessa että ratkaisuprossien avaamisessa. Tuloksista on nähtävissä, että oppilailla oli taitoja kielentää monipuolisesti matemaattista ajatteluaan. Matematiikan opetuksessa olisikin hyvä ohjata oppilaita ilmaisemaan matemaa…

Scientific productivity and collaboration in viticulture and enology in Latin American countries

2013

[EN] The aim of this study was to analyze the scientific activity of Latin American researchers in viticulture and oenology through bibliometric analyses of articles included in the Science Citation Index Expanded database for the period of 2006 to 2010. A total of 917 research articles were published in 364 domestic and international journals. We highlight the important growth in the number of research papers published during the period, especially in Brazil, Argentina and Chile, as well as an increasing number of international collaborations, mainly with non-American grape- and-wine producing countries. A social network analysis of collaborations between institutions and countries was als…

PECULIARE EVOLUZIONE DELLA SEMEIOTICA NEURORADIOLOGICA DI UN CASO DI MALATTIA DEMIELINIZZANTE CON LESIONI PSEUDOTUMORALI

2013

SCOPO DEL LAVORO Presentiamo un caso di una paziente di 24 anni che giunge alla nostra attenzione per la comparsa di disartria come quadro clinico d’esordio di una forma aggressiva di malattia demielinizzante di cui si valuta l’atipica evoluzione neuroradiologica delle lesioni pseudotumorali che la caratterizzano e le possibili diagnosi differenziali. MATERIALI E METODI La paziente dopo una prima valutazione in PS è stata sottoposta a TC encefalo, ricoverata presso l’U.O. di Neurologia, sottoposta a controlli RM seriati (anche con tecniche avanzate); durante la degenza è stata inoltre effettuata una biopsia stereotassica. RISULTATI La TC ha rilevato almeno tre lesioni ipodense: a sinistra…

CARATTERISTICHE NEURORADIOLOGICHE DI UN CASO DI SCLEROSI TUBEROSA DIAGNOSTICATO IN ETÀ ADULTA

2013

SCOPO DEL LAVORO: presentiamo un caso di Sclerosi Tuberosa (Tuberous sclerosis complex, TSC; anche nota come Sindrome di Bourneville-Pringle) diagnosticato tardivamente grazie al sospetto posto dalle indagini neuroradiologiche eseguite in una paziente di 40 anni con in anamnesi ritardo mentale, crisi epilettiche e disturbi del visus.MATERIALI E METODI: la paziente si presenza alla nostra attenzione per un episodio di disorientamento e confusione mentale; dopo una prima valutazione in PS veniva eseguita una TC dell’encefalo in tecnica sequenziale (Siemens SOMATON AS+, 128 strati) e trasferita presso l’U.O.C. di Neurologia. In seguito, per una migliore caratterizzazione dei reperti descritti …

Towards a framework for assessment and management of cumulative human impacts on marine food webs

2015

Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…

DETERMINATION OF ABUSED SUBSTANCES IN BIOLOGICAL MATRICES FOR TOXICOLOGICAL AND FORENSIC PURPOSES

2019

During the year 2017, a research work was carried out at the Department of laboratory diagnostics - Toxicology and Biochemistry U.O.S. of ASP 6 in Palermo. The purpose of this investigation was to perform a second level analysis in order to look for abuse drugs. The sample used consisted of 73 serum tubes, which had previously tested positive for screen- ing tests. The result of the analysis of these samples revealed a false positivity in most cases. From the information gathered through the sampling reports, it appears that the age group with several drivers, who are subject to checks by the traffic police, is the one from 17 to 30 years, with 35 samples analysed (48%). It also emerged tha…
