Vascular Risk Factors in Mild Cognitive Impairment Subtypes
2007
<i>Background and Aim:</i> To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. <i>Methods:</i> Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. <i>Results:</i> snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and …
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…

Factors associated with the timing of diagnosis of venous thromboembolism: results from the MASTER registry
2008
INTRODUCTION: Signs and symptoms of venous thromboembolism (VTE) are non-specific and thus can make diagnosis difficult, even for an experienced clinician. We aimed to evaluate the timing of diagnosis of deep vein thrombosis (DVT) and pulmonary embolism (PE) in Italian hospitals and to identify individual and clinical predictors of timely or delayed diagnosis. MATERIAL AND METHODS: MASTER is a multicenter prospective registry of patients with acute DVT and PE. Information on clinical presentation and diagnostic methods, temporary and permanent risk factors, were captured by an electronic data network at the time of the index event. RESULTS: Data on 2047 patients (1024 males), 1505 with DVT …
Diagnostika vladeniâ finskim i russkim pis'mennym âzykom russkoâzyčnymi učenikami, živuŝimi v Finlândii
2016
Tässä pro gradu -tutkielmassa tarkastellaan venäjää kotikielenään puhuvien oppilaiden suomen ja venäjän kielen kirjallisten taitojen diagnosointia. Tutkimuksen tavoitteena on selvittää miten venäjä äidinkielenä ja suomi toisena kielenä opettajat ottavat oppilaan taustan huomioon, miten he diagnosoivat heidän kielellisiä vahvuuksia sekä heikkouksia ja kuinka he auttavat oppilaitaan vaikeuksien ilmetessä. Aihe on ajankohtainen, sillä venäjänkielisten määrä Suomessa on kasvanut viime vuosina nopeasti. Tilanne näkyy myös koulumaailmassa: venäjänkielisten oppilaiden määrä Suomen kouluissa kasvaa jatkuvasti. Oppimisvaikeuksien diagnosoinnista äidinkielen osalta on jo paljon tutkimustietoa, mutta …
Exercise as stimulus for cartilage health in knee osteoarthritis
2018
Knee osteoarthritis (OA) is a leading cause of musculoskeletal pain and disability and has significant socio-economical costs globally. There is no known cure for OA. Therapeutic exercise has been shown to evoke acute positive posttreatment effects on pain and function. Even though cartilage degeneration is crucial in OA progression, there is sparse knowledge about exercise effects on osteoarthritic cartilage. The purpose of this study was to investigate the efficacy of aquatic resistance training on the estimated biochemical composition of tibiofemoral cartilage and the association between leisure time physical activity (LTPA) and tibiofemoral cartilage in postmenopausal women with mild kn…
Quantum coherent manipulation of spin information in molecular nanomagnets
2023
Los sistemas cuánticos de dos niveles basados en estados de espín, conocidos como ``qubits de espín'', son bloques prometedores para el desarrollo de tecnologías cuánticas. Entre las distintas plataformas físicas, los qubits de espín definidos en imanes de molécula única (SMM) son candidatos prometedores porque su estructura electrónica puede ajustarse fácilmente mediante ingeniería química (es decir, el Hamiltoniano de espín molecular puede modificarse con facilidad). Sin embargo, los qubits moleculares de espín generados en SMM se enfrentan a varios retos: coherencia cuántica frágil, control coherente insuficiente de los estados de espín y generación de entrelazamiento entre los qubits de…
Akūta vidusauss iekaisuma diagnostika, ārstēšana un iznākumi bērnu ambulatorajā ārstnieciskajā praksē
2015
Tēmas aktualitāte: Akūts vidusauss iekaisums (AVI) joprojām ir viena no biežākajām bērnu infekcijas slimībām. Tas tiek uzskatīts arī kā galvenais antibiotiku ordinēšanas iemesls bērniem- gan Eiropā, gan citur pasaulē. Pareizai slimības diagnostikai un terapijai ir svarīga nozīme iespējamo AVI komplikāciju prevencijā. Darba mērķis: Retrospektīvā un prospektīvā pētījumā noskaidrot, pēc kādām pazīmēm un simptomiem Latvijas bērnu veselības aprūpes sistēmā tiek noteikta akūta vidusauss iekaisuma diagnoze, kāda terapija tiek ordinēta un kādi ir slimības iznākumi, salīdzināt pētījumā iegūtos rezultātus ar literatūrā pieejamiem datiem un rekomendācijām. Metodes un materiāli: Pētījuma retrospektīvaj…
Sustaining Attention for a Prolonged Duration Affects Dynamic Organizations of Frequency-Specific Functional Connectivity
2020
Sustained attention encompasses a cascade of fundamental functions. The human ability to implement a sustained attention task is supported by brain networks that dynamically formed and dissolved through oscillatory synchronization. The decrement of vigilance induced by prolonged task engagement affects sustained attention. However, little is known about which stage or combinations are affected by vigilance decrement. Here, we applied an analysis framework composed of weighted phase lag index (wPLI) and tensor component analysis (TCA) to an EEG dataset collected during 80 min sustained attention task to examine the electrophysiological basis of such effect. We aimed to characterize the phase…
