Distribution of VP7 serotypes and VP4 genotypes among rotavirus strains recovered from Italian children with diarrhea

1997

108 rotavirus strains obtained from children with diarrhea hospitalized in Palermo, Italy, in the years 1990-1994, were examined by seminested PCR to study the relative frequency and distribution of the four most common alleles of the gene 4. Such strains were selected from 344 human rotavirus strains recovered in palermo during those years after characterization by electropherotyping, subgrouping and G serotyping. One hundred and seven of the 108 strains could be classified into P types, the P[8], G1 (38.3%) and the P[8], G4 (52.3%) types being predominant. The unique strain whose P genotype could not be identified showed an unusual combination of long migration electrophoretic pattern and…

Evaluation and management of hemorrhoids: Italian society of colorectal surgery (SICCR) consensus statement

2015

Hemorrhoids are one of the most common medical and surgical diseases and the main reason for a visit to a coloproctologist. This consensus statement was drawn up by the Italian society of colorectal surgery in order to provide practice parameters for an accurate assessment of the disease and consequent appropriate treatment. The authors made a careful search in the main databases (MEDLINE, PubMed, Embase and Cochrane), and all results were classified on the basis of the grade of recommendation (A-C) of the American College of Chest Physicians.

Tyttö- ja poikalukijoiden representaatiot suomalaisissa uutisteksteissä

2017

Tämän tutkimuksen tavoitteena on selvittää, miten suomalaisnuorten lukutaitoa ja lukemista sukupuolittuneena ja sukupuolittavana ilmiönä merkityksellistetään uutisteksteissä. Teema on hyvin ajankohtainen, sillä 2000-luvulla tehtyjen PISA-tutkimusten myötä tyttöjen ja poikien erilainen lukutaitomenestys on noussut merkittäväksi puheenaiheeksi joukkotiedotusvälineissä. Alan asiantuntijat tarjoavat erilaisia malleja ja syitä tyttöjen menestymiseen ja poikien epäonnistumiseen sekä esittävät lukemisen opetusta koskevia muutosvaatimuksia. Tutkimusaihe on tärkeä,koska kielenkäytössä pyritään oikeuttamaan pedagogisia linjauksia, jotka koskevat sukupuolta ja lukemisen opetusta. Lisäksi kielenkäytöll…

Biogenic amine levels, reproduction and social dominance in the queenless ant Streblognathus peetersi

2006

Social harmony often relies on ritualized dominance interactions between society members, particularly in queenless ant societies, where colony members do not have developmentally predetermined castes but have to fight for their status in the reproductive and work hierarchy. In this behavioural plasticity, their social organisation resembles more that of vertebrates than that of the "classic" social insects. The present study investigates the neurochemistry of the queenless ant species, Streblognathus peetersi, to better understand the neural basis of the high behavioural plasticity observed in queenless ants. We report measurements of brain biogenic amines [octopamine, dopamine, serotonin]…

Rewarding effects of 3,4-methylenedioxymethamphetamine (“Ecstasy”) in dominant and subordinate OF-1 mice in the place preference conditioning paradigm

2006

We tested the ability of 3,4-methylenedioxymethamphetamine (MDMA) to induce conditioned place preference (CPP) in dominant and subordinate OF-1 mice subjected to cohabitation and repeated sessions of agonistic confrontation, as well as in non-confronted mice. We selected doses of MDMA (2, 6, 10 mg/kg) previously reported to induce CPP in mice and we measured expression of c-Fos evoked by the treatments in non-confronted mice. MDMA induced c-Fos protein in several corticolimbic regions involved in drug-induced reward. Mice were exposed to brief sessions of agonistic confrontation on 5 consecutive days. Determinations of circulating hormones and drug conditioning tests were carried out on com…

Low incidence of Vibrio vulnificus among Vibrio isolates from sea water and shellfish of the western Mediterranean coast.

1999

A specific search for Vibrio vulnificus in natural marine samples from the Spanish Mediterranean Sea was carried out by nested PCR and cultural approaches using thiosulphate-citrate-bile salts-sucrose agar (TCBS) and cellobiose-polymixin B-colistin agar (CPC), incubated at 40 degrees C, as selective media. Presumptive colonies were identified by PCR using specific primers against 23S rRNA sequences. This species was isolated from sea water and edible bivalves, mainly after preenrichment in alkaline peptone water (APW) at 40 degrees C followed by CPC agar. None of the V. vulnificus isolates identified corresponded to serovar E. Dominant Vibrio species on directly inoculated TCBS plates incub…

From the Golgi-Cajal mapping to the transmitter-based characterization of the neuronal networks leading to two modes of brain communication: Wiring a…

2007

After Golgi-Cajal mapped neural circuits, the discovery and mapping of the central monoamine neurons opened up for a new understanding of interneuronal communication by indicating that another form of communication exists. For instance, it was found that dopamine may be released as a prolactin inhibitory factor from the median eminence, indicating an alternative mode of dopamine communication in the brain. Subsequently, the analysis of the locus coeruleus noradrenaline neurons demonstrated a novel type of lower brainstem neuron that monosynaptically and globally innervated the entire CNS. Furthermore, the ascending raphe serotonin neuron systems were found to globally innervate the forebrai…

Spontaneous Epileptic Manifestations in a DCX Knockdown Model of Human Double Cortex

2010

Previous reports indicate that in utero knockdown of doublecortin (DCX) results in the genesis of a subcortical heterotopia reminiscent of the doublecortex observed in female patients with DCX mutations. It has also been shown that these rats display an increased susceptibility to convulsant agents and increased cortical neurons excitability; but it is presently unknown whether they display spontaneous seizures. Furthermore, the link between the size of heterotopia and the clinical manifestation remained to be elucidated. Using video--electrocorticogram recordings, we now report that DCX knockdown induces frequent spontaneous seizures commonly associated with myoclonic jerks in adult rats. …

Serotonīna ietekme uz augļu mušu (Drosophila melanogaster) fototaksi

2022

Serotonīns ir iesaistīts daudzos svarīgos procesos dzīvo būtņu organismos, sākot no nervu impulsu pārraidi, garastāvokļa izmaiņām, depresiju un beidzot ar peristaltikas un zarnu trakta darbības regulēšanu. Cilvēka centrālā nervu sistēma psihisko slimību kontekstā ir sarežģīts mehānisms un tā izpēte tiešā veidā nav iespējama. Līdz ar to eksperimentos, depresijas un ar to saistītās uzvedības, izpētei vieglāk izmantot bioloģijā klasisko modeli – augļu mušas Drosophila melanogaster. Šī organisma bāziskas ķīmiskas reakcijas smadzenēs ir līdzīgas reakcijām, kas norisinās cilvēka smadzenēs; turklāt augļu mušas jau tiek izmantotas par cilvēka depresijas modeļorganismu. Eksperimentā tika izmantotas …
