Rendimiento neuropsicológico en pacientes que demandan tratamiento por consumo de drogas
2015
El estudio sobre los déficits neuropsicológicos en adicciones ha cobrado una especial relevancia en las últimas décadas, lo que se debe fundamentalmente a sus implicaciones en aspectos tan importantes como el pronóstico terapéutico y el diseño de estrategias adecuadas de intervención (Landa, Fernández y Tirapu, 2004; Madoz, Ochoa y Martínez, 2009). Sin embargo, y a pesar de que el policonsumo de sustancias constituye un patrón de consumo cada vez más prevalente en la población general (DGPNSD, 2013), tanto los servicios asistenciales de demanda de tratamiento como la investigación previa, suelen informar de la sustancia principal por la que el paciente acude a tratamiento, no ofreciendo inf…
Effect of different hydrothermal vent conditions in the proteome of vent mussel Bathymodiolus azoricus
2009
The mytilid mussel Bathymodiolus azoricus is the most representative species of north Mid Atlantic Ridge (MAR) hydrothermal vents and is abundantly found at Menez-Gwen, Lucky Strike and Rainbow vent sites. info:eu-repo/semantics/publishedVersion
Influence of uniaxial pressure and aging on dielectric and ferroelectric properties of BaTiO3ceramics
2013
The effect of uniaxial pressure (0–3000 bar) applied parallel to the AC electric field and aging on dielectric and ferroelectric behavior of BaTiO3 ceramics were investigated. Applying uniaxial pressure leads to a reduction of the peak intensity of the electric permittivity (e) of the polarization as well as of the dielectric hysteresis. The peak intensity of e becomes diffused and shifts to a higher temperatures with increasing the pressure. The electrostrictive coefficient Q 11 and differential permittivity were evaluated from the obtained data. We interpreted our results based on the hardening of the soft-mode and domain switching processes under the action of pressure. The aging effect …
IMPORTANCE OF BAT UNDERGROUND ROOSTS AND LONG-TERM CHANGES OF BAT POPULATIONS IN LATVIA
2013
Anotācija Darbā aplūkotas trīs tēmas: sikspārņu ziemošanas mītņu raksturojums, šo mītņu izmantošana dažādās sezonās un ziemojošo un migrējošo sikspārņu populāciju skaita izmaiņas. Analizēti 35 gadu laikā Latvijā ievākti dati par 994 ziemojošo sikspārņu sugu izmantotajām ziemas mītnēm. Izvērtēta šo mītņu nozīmība dažādām ziemojošajām sikspārņu sugām un aplūkota to izmantošana citās sezonās. Vislielākā sikspārņu sugu daudzveidība konstatēta alās, vislielākās ziemojošo sikspārņu populācijas – fortu tipa mītnēs un – divām sugām - mazajos piemāju pagrabos. Konstatēts, ka sikspārņi izmanto ziemošanas mītnes visa gada garumā. Divām sugām aprēķināts mazajos piemāju sakņu pagrabos ziemojošās populāc…
L'impact méconnu des chauves-souris et du guano dans l'évolution morphologique tardive des cavernes
2016
The little known impact of bats and bat guano in the late stages of cave morphogenesis. Bats are considered as symbolic caves inhabitants. The colonies, sometimes huge, may occupy caves through long periods. Large guano deposits were accumulated. Some have been mined for phosphates, either by hand or at the industrial scale. Bats impact is triple: breathing releases CO2, urine is corrosive, and guano mineralization releases acids (carbonic, nitric, sulfuric, and phosphoric). Such aggressive compounds have an effect on carbonate rock and flowstones, either by direct ground corrosion at the contact of the guano, or by condensation-corrosion on walls and ceilings. The speleogenetic impact of t…
Spinal epidural abscess due to acute pyelonephritis
2022
Background: Spinal epidural abscesses are rare and are misdiagnosed in up to 75% of cases. Fever, back pain, and neurological deficits are part of the classical triad. Here, the authors report a patient with a L2–L5 spinal epidural abscess with the left paravertebral extension attributed to acute pyelonephritis. Case Description: A 54-year-old female presented with persistent low back pain and lower extremity weakness accompanied by paresthesias. Previously, she had been hospitalized with the left acute pyelonephritis. The lumbosacral MRI documented a T12/L5 anterior epidural abscess with ring enhancement on the contrast study; the maximum diameter of the abscess at the L2–L3 level contrib…
IsBattarrea phalloidesreally an endangered species?
2020
Battarrea phalloides (Basidiomycota), a fungus included in many Red Lists worldwide, requires verification of its real conservation status. One of the main problems in the assessment of fungal spec...
The neuronal ceroid-lipofuscinoses: A historical introduction
2013
AbstractThe neuronal ceroid-lipofuscinoses (Batten disease) collectively constitute one of the most common groups of inherited childhood onset neurodegenerative disorders, and have also been identified in many domestic and laboratory animals. The group of human neuronal ceroid-lipofuscinoses currently comprises 14 genetically distinct disorders, mostly characterised by progressive mental, motor and visual deterioration with onset in childhood or adolescence. Abnormal autofluorescent, electron-dense granules accumulate in the cytoplasm of nerve cells, and this storage process is associated with selective destruction and loss of neurons in the brain and retina. The present paper outlines near…
BIODIVERSITA’ DELLE COMUNITA’ BATTERICHE IN UN SUOLO SOTTOPOSTO A BIORISANAMENTO IN MICROCOSMO
2021
Gli idrocarburi (HC) sono uno dei principali inquinanti ambientali. Una tecnologia promettente per il trattamento di siti contaminati si basa sulla biodegradazione degli inquinanti da parte di popolazioni microbiche capaci di utilizzare HC come fonte di carbonio ed energia (Biorisanamento). La necessità di risanare siti contaminati richiede da una parte la caratterizzazione delle comunità microbiche coinvolte nella biodegradazione, dall’altra lo sviluppo di interventi volti a migliorare il potenziale metabolico dei microrganismi degradatori. La nostra attività di ricerca ha avuto come obiettivo quello di caratterizzare e analizzare la biodiversità di comunità microbiche di un suolo contamin…
Biotecnologie applicate alla valorizzazione della “Pagnotta di Piana degli Albanesi”
2019
Il presente articolo riassume il progetto di valorizzazione della Pagnotta di Piana degli Albanesi attraverso lo sviluppo di un impasto acido ottenuto da batteri lattici selezionati dalle materie prime, al fine di legare la produzione al territorio e permettere di recuperare le note di tipicità. Le farine e le semole rappresentano dei veri e propri habitat microbici, la cui composizione può variare in funzione dell’area geografica e delle condizioni di conservazione. Trattandosi di materie prime che non possono essere trattate termicamente prima della trasformazione, esse trasferiscono i loro microrganismi al prodotto in lavorazione. Pertanto, qualora tali microorganismi esprimano proprietà…
