Darbinieku kontroles sistēma, izmantojot biometrijas datus
2019
Kvalifikācijas darba mērķis ir izstrādāt darbinieku kontroles sistēmu, kura izmanto biometrijas datus (sejas atpazīšanu), un ar kuras palīdzību var koordinēt un pārvaldīt firmas darbinieku darbības un to personīgos datus, un tas ļauj efektīvāk organizēt uzņēmuma darbību. Šī sistēma ir izveidota C++ programmēšanas valodā izmantojot QT Creator ietvaru un atvērtā koda bibliotēku OpenCv. Sistēmas dati tiek glabāti SQLite datubāzē. Sistēma tika veidota izmantojot gan ūdenskrituma (waterfall) modeli, gan spējas (agile) izstrādes metodes. Sistēma sastāv no 4 moduļiem - autentificēšanās, lietotāja, atpazīšanas, atskaišu.
Association between Tpeak-Tend/QT and major adverse cardiovascular events in patients with Takotsubo syndrome
2020
Background:Conflicting results have been described in the scientific literature regarding the relationship between electrocardiographic parameters and complications in patients with Takotsubo syndrome (TTS). Aim of the present study was to investigate whether there is an association between markers of ventricular repolarization and major adverse cardiovascular events (MACE) during hospitalisation. Methods:A retrospective chart review was conducted on a sample of patients with diagnosis of TTS, based on the fulfilment of the revised Mayo Clinic criteria. MACE included acute heart failure, cardiogenic shock, sustained ventricular tachycardia, ventricular fibrillation, and death. The following…

Bis(4-methylthio)phenylthiomethane as assembling ligand for the construction of Cu(I) and Hg(II) coordination polymers. Crystal structures and topolo…
2016
International audience; The novel 1D coordination polymer (CP) [{Cu(mu(2)-Br)(2)Cu}(mu-L2)(2)] CP2 has been obtained by reaction of the tetrakisthioether p-MeSC6H4SCH2SC6H4SMe-p (L2) with CuBr in a 1: 2 metal-to ligand ratio. In contrast to the previously described CP [{Cu(mu(2)-Br)(2)Cu}(mu-L1)(2)] CP1 obtained by reaction of the tetrakisthioether p-MeOC6H4SCH2SC6H4OMe-p (L1) with CuBr, the two independent extended 1D ribbons contain bent Cu(mu(2)-Br)(2)Cu units of the butterfly-type with short Cu center dot center dot center dot Cu separations of 2.679(1) and 2.613(1) angstrom. In contrast to the common planar rhomboid Cu(mu(2)-Br)(2)Cu cluster, this butterfly-shaped geometry of the core …
Estudio de perfilación de metabolitos secundarios de extractos vegetales obtenidos mediante técnicas y estrategias no convencionales para el desarrol…
2022
En esta tesis doctoral se desarrolló en el entorno de la economía verde y el reciclaje de residuos alimentarios estudiando diferentes técnicas de extracción no convencionales. En primer lugar, se aislaron polifenoles de matrices complejas producto del desperdicio de alimentos, como son las hojas de Moringa oleifera, mediante extracción asistida por ultrasonidos (UAE). El enfoque de diseño experimental permitió optimizar las mejores condiciones de extracción (MeOH:H2O 50:50, v/v, proporcion 1:60 Sólido/Líquido (S/L), 60°C, 60 min) para obtener un contenido fenólico total (TPC) de 13,4 mg expresados como equivalentes de ácido gálico (GAE)/g de materia seca. Por lo tanto, la caracterización y …
QT intervāla izmaiņas pie alkohola intoksikācijas
2020
QT intervāls ir viens no elektrokardiogrammas intervāliem, ja tas pagarinās, tad tas var novest pie neregulāra sirds ritma, kā arī samaņas zuduma, un pat nāvei. Alkohols (etanols) ir viena no vielām, kas pēc literatūras avotiem pagarina QT intervālu. QT dispersija ir starpība starp garāko un īsāko QT intervālu. Tā ir netiešs repolarizācijas heterogenitātes marķieris. QT dispersija virs normas var norādīt uz malignas kambaru aritmijas predispozīciju. Pētījuma mērķis: Analizēt QT intervāla un tā derivātu (QTd, QTc) izmaiņas pacientiem pie alkohola intoksikācijas salīdzinot šos datus ar kontroles grupu. Materiāli un metodes: Retrospektīvs pētījums, kurā tika izmantotas 100 pacientu vēstures. 7…
The impact of study design and diagnostic approach in a large multi-centre ADHD study. Part 1: ADHD symptom patterns
2011
Contains fulltext : 96439.pdf (Publisher’s version ) (Open Access) BACKGROUND: The International Multi-centre ADHD Genetics (IMAGE) project with 11 participating centres from 7 European countries and Israel has collected a large behavioural and genetic database for present and future research. Behavioural data were collected from 1068 probands with the combined type of attention deficit/hyperactivity disorder (ADHD-CT) and 1446 'unselected' siblings. The aim was to analyse the IMAGE sample with respect to demographic features (gender, age, family status, and recruiting centres) and psychopathological characteristics (diagnostic subtype, symptom frequencies, age at symptom detection, and com…
Chemical composition, cytotoxic effects, antimicrobial and antibiofilm activity of Artemisia arborescens (Vaill.) L. growing wild in the province of …
2022
Artemisia arborescens (Vaill.) L. is a perennial shrubby plant growing along the coastal strips of the Mediterranean region. It is used in traditional medicine. Its essential oil and solvent extracts exhibit a very interesting chemotherapeutic potential, which makes this plant useful in maintaining human health. The goal of this study was to determine the phytochemical composition of the petroleum ether and methanol extracts, as well as to evaluate anticancer activities and antimicrobial and biofilm formation reduction. Thirty-nine phytochemical compounds in negative ion mode, and 25 in positive ion mode were identified by HPLC-ESI-QTOF-MS. All four extracts reduced the viability of human M…
Un nuovo caso di microdelezione 15qter: valutazioni cliniche, genetiche e molecolari
2008
Per una migliore comprensione patogenetica del ritardo mentale (RM) in combinazione o meno con le manifestazioni malformative, i tests di laboratorio sono di notevole importanza. La metodica CGH Array ha migliorato la sensibilità nella valutazione dei punti di rottura nelle delezioni cromosomiche. Qui presentiamo un caso di delezione 15q26.2-15qter in un bambina con medie note dismorfiche esterne (come la clinodattilia), interne (doppio distretto renale a destra) ed alcune alterazioni del linguaggio. L'analisi GCH Microarray è stata effettuata estraendo da linfociti di sangue periferico (Puregene DNA isolation kit, Gentra) e marcando (Cy5) il DNA del probando e realizzando l'Array CGH (Agil…
What links BRAF to the heart function? new insights from the cardiotoxicity of BRAF inhibitors in cancer treatment
2015
The RAS-related signalling cascade has a fundamental role in cell. It activates differentiation and survival. It is particularly important one of its molecules, B-RAF. B-RAF has been a central point for research, especially in melanoma. Indeed, it lacked effective therapeutic weapons since the early years of its study. Molecules targeting B-RAF have been developed. Nowadays, two classes of molecules are approved by FDA. Multi-target molecules, such as Sorafenib and Regorafenib, and selective molecules, such as Vemurafenib and Dabrafenib. Many other molecules are still under investigation. Most of them are studied in phase 1 trials. Clinical studies correlate B-RAF inhibitors and QT prolonga…
