Role of post mortem computed tomography in diagnosis of upper cervical fractures in child due to road accident: A case report and literature review
2019
The upper cervical spine has unique anatomical features that distinguish it from the remainder of the cervical spine. Its motion segments make up a large amount of total cervical spine motion and, as a result,predispose it to a unique set of injuries. Cervical spine trauma is a common problem with a wide range of severity from minor ligamentous injury to section of the spinal cord. The use of post mortem CT (PMCT), and the subsequent multi-planar and volume rendering reconstruction techniques can provide non-invasive, objective operator-independent imaging data set that may be further reviewed by other specialists. and can substantially add to forensic examinations of the skeleton, especial…

Estudi clínic,neuropsicològic i de Ressonància magnètica de l´Esclerosi Múltiple primària progressiva
2015
L´esclerosi múltiple primària progressiva es presenta entre un 10-15 % dels pacients, ve definida per un curs progressiu sense brots clars i amb una presentació típica en forma de paraparèsia espàstica fins en un 80 % dels casos. No disposa de tractament aprovat modificador de la malaltia en l´actualitat si bé s´ha vist en base a estudis d´inflamació en LCR que podria existir un subgrup que tindrien un perfil clínic diferent amb inflamació i es podrien beneficiar de tractament. Es tracta doncs, d’un subtipus d’ EM que suposa un repte per a la pràctica clínica, caracteritzat per la progressió inevitable de la discapacitat. És per això que el nostre estudi es va basar en explorar el patró clí…

The role of lipid metabolism in the acquisition of desiccation tolerance inCraterostigma plantagineum: a comparative approach
2013
Summary Dehydration leads to different physiological and biochemical responses in plants. We analysed the lipid composition and the expression of genes involved in lipid biosynthesis in the desiccation-tolerant plant Craterostigma plantagineum. A comparative approach was carried out with Lindernia brevidens (desiccation tolerant) and two desiccation-sensitive species, Lindernia subracemosa and Arabidopsis thaliana. In C. plantagineum the total lipid content remained constant while the lipid composition underwent major changes during desiccation. The most prominent change was the removal of monogalactosyldiacylglycerol (MGDG) from the thylakoids. Analysis of molecular species composition rev…
Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.
2011
Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…
From soil to soil-less in horticulture: quality and typicity
2013
In this review, the technique of soil-less cultivation of horticultural crops is analysed, the main differences between this and traditional cultivation techniques are described, and the advantages and disadvantages of each method in relation to the others are identified. Soilless cultivation has revolutionised various sectors of vegetable and floriculture production, and recent years have also seen interest being shown by Italian fruit crop producers, particularly those involved in table grape viticulture. The various issues related to the use of this technique are described in relation to the needs of the substrate, water management, and mineral nutrition of the different species, and to …
Minervan miehet : tieteellisen antikvariaatin kirjanvälitystoimintaa akateemisissa verkostoissa
2020
Tutkin artikkelissani henkilö- ja verkostohistoriallisesta näkökulmasta antikvaarista kirjakauppaa, jota käytiin Helsingin yliopiston opiskelijoiden ja tutkijoiden muodostamissa akateemisissa verkostoissa. Minerva Oy oli 1800- ja 1900-luvun vaihteessa Helsingissä toiminut tieteellinen antikvaarinen kirjakauppa. Tarkastelen Minerva-osakeyhtiön historiaa 1890-luvulta 1910-luvulle sen piirissä toimineiden henkilöiden kautta hyödyntämällä kollektiivibiografista menetelmää. Pohdin, miten ja miksi akateemiset henkilöverkostot edesauttoivat liikkeen kirjanvälitystoimintaa. Minervan perustajat ja keskeiset toimijat tunsivat toisensa opiskeltuaan ja työskenneltyään Helsingin yliopiston piirissä. Näi…
Intratympanic gentamicin: a one day protocol treatment for unilateral Meniere’s disease.
2007
Purpose: The objective of this study was to assess the usefulness of low-dose intratympanic gentamicin administration in patients with Meniere’s disease (MD). Materials and Methods: We carried out a retrospective review of the charts of 55 patients with definite MD in accordance with the AAO-HNS (American Academy of Otolaryngology–Head and Neck Surgery) Diagnostic Scale who were treated at Gruppo Otologico (Piacenza, Rome, Italy). The treatment protocol consisted of 3 intratympanic injections of gentamicin at a 12-hour interval between each administration. Results: Results were resumed in accordance with AAO-HNS criteria and showed complete control of vertigo spells in 60% (class A), good c…
Neuropsychological and psychophysiological profile of intimate partner violence perpetrators men: the role of alcohol
2018
La violencia contra la mujer en las relaciones de pareja hombre-mujer, representa un grave problema de salud pública a nivel mundial. En los últimos años, una mayor evidencia científica sustenta la relación entre la violencia contra la mujer y el consumo de alcohol. Sin embargo, existe un vacío en la literatura sobre los efectos que ejerce el consumo de alcohol sobre las variables neuropsicológicas y psicofisiológicas en los hombres que han cometido violencia contra la mujer. El consumo de alcohol podría predisponer a los agresores a presentar alteraciones cognitivas que afecten a su regulación emocional y comportamental y, por tanto, predisponer a conductas violentas en situaciones estresa…
