Becton Dickinson Directigen EZ Flu A+B assay in the diagnosis of pandemic influenza A H1N1 2009 virus infection in adult patients
2011
To the editor: The recent emergence and spread of the pandemic influenza A H1N1 2009 virus demands the evaluation of rapid antigen assays for their ability to detect this novel subtype of influenza A virus. Data on the ability of BD Directigen EZ Flu A+B immunochromatographic (IC) assay (Beckton Dickinson and Company, Sparks, MD, USA) to detect the pandemic influenza A virus strain in fresh clinical samples have been recently published. 1 , 2 , 3 , 4 , 5 In these studies, the majority of specimens were collected from pediatric patients, and the sensitivities reported ranged from 46·8% to 76·6%. As viral shedding in the upper respiratory tract during influenza virus infection is of greater m…
Analysis of Relationship between Net Wage and Consumer Price Index
2013
Abstract In the present paper is presented an econometric analysis of the relationship between net salary and consumer price index. After a brief historical overview will be review the calculating statistics for selected variables and coefficients and will be presented the obtained values. We will study the relationship between variables. It will be realized the cloud of points and will be applied Fisher test. The intensity of selected variables will be study too and some forms of relationship between the two chose variables will be done. Student test is applied. It will be performed the parameter estimation for regression functions and Akaike's criterion will be applied. The homoscedastici…
Effectiveness of an exercise training program on youth with Asperger syndrome
2009
Although exercise training programs are effective in improving physical fitness and motor competence in typically developing youth, insufficient data of the impact of interventions are available in youth with Asperger syndrome (AS). The purpose of this study was to examine the efficacy of an exercise program as part of an ongoing vocational training program for adolescents with AS on motor competence and physical fitness. Twenty adolescents with AS (mean age = 16.8yrs) were enrolled in this study. A quasi-experimental nonequivalent-control-group design with a follow-up measurement over a period of six months was followed. The intervention group received a 12-week physical exercise program f…
Diagnosis and Treatment of Lower Extremity Venous Thromboembolism
2020
Importance: Incidence rates for lower extremity deep vein thrombosis (DVT) range from 88 to 112 per 100 000 person-years and increase with age. Rates of recurrent VTE range from 20% to 36% during the 10 years after an initial event.Observations: PubMed and Cochrane databases were searched for English-language studies published from January 2015 through June 2020 for randomized clinical trials, meta-analyses, systematic reviews, and observational studies. Risk factors for venous thromboembolism (VTE), such as older age, malignancy (cumulative incidence of 7.4% after a median of 19 months), inflammatory disorders (VTE risk is 4.7% in patients with rheumatoid arthritis and 2.5% in those withou…
Improving the cementation of the tibial component in knee arthroplasty : a study of four techniques in the cadaver.
2021
Aims The main objective of this study is to analyze the penetration of bone cement in four different full cementation techniques of the tibial tray. Methods In order to determine the best tibial tray cementation technique, we applied cement to 40 cryopreserved donor tibiae by four different techniques: 1) double-layer cementation of the tibial component and tibial bone with bone restrictor; 2) metallic cementation of the tibial component without bone restrictor; 3) bone cementation of the tibia with bone restrictor; and 4) superficial bone cementation of the tibia and metallic keel cementation of the tibial component without bone restrictor. We performed CT exams of all 40 subjects, and mea…
Induktīvās un deduktīvās pieejas izmantošana darbības vārdu laiku mācīšanā augstskolā: salīdzinošā analīze
2018
Gramatika vienmēr tiek uzskatīta par vienu no galvenajiem aspektiem svešvalodu apguvē. Ir zināmas divas galvenās un, savā ziņā, pretrunīgas metodes gramatikas apmācībā, tādas kā deduktīvā un induktīvā metodes. Šī pētījuma mērķis bija noskaidrot, vai studentu sasniegumi angļu valodas apguvē būtiski atšķiras atkarībā no tā, vai darbības vārdu laikus māca deduktīvi vai induktīvi. Pētniecības metode, kas izmantota maģistra darbā bija darbības pētījums, un datu vākšanas instrumenti bija testi un anketas. Pētījuma dalībnieku skaits bija divdesmit astoņi pirmā kursa bakalaura studenti, kuri specializējas angļu filoloģijā kādā Latvijas universitātē. Pētījuma rezultāti parādīja, ka nav novērojama st…
Sosiaalinen oppiminen eläinmallissa
2016
Tässä kokeellisessa tutkimuksessa tarkasteltiin sosiaalista oppimista eläinmallissa, jonka keskiössä olivat rotat ja niiden oppimisen sosiaalisuus. Tätä ilmiötä lähestyttiin pohtimalla kysymyksiä: (1) eroavatko rotat lajikannan (HCR - LCR) tai (2) oppimistyylin (itsenäinen - toiselta mallintava) suhteen, sekä (3) eroavatko viivästetyn ja viiveettömän sosiaalisen oppimisen ryhmät toisistaan. Toisin sanoen tutkimuksessa sosiaalinen oppiminen miellettiin rottien käyttäytymisessä tapahtuviksi muutoksiksi, joiden mahdollista ilmenemistä voitiin tarkastella useilla mittauskerroilla. Tutkimuksen koeryhmä muodostui urosrotista (N = 18), joissa oli HCR-rottia (n = 10) ja LCR-rottia (n = 8). Koeasete…
Effects of 5-Week of FIFA 11+ Warm-Up Program on Explosive Strength, Speed, and Perception of Physical Exertion in Elite Female Futsal Athletes
2022
Futsal is a sport that originates from soccer and is increasingly practiced all over the world. Since training and warm-up protocols should be sport-specific in order to reduce injuries and maximize performance, this study aimed to evaluate the effects of 5 weeks of the FIFA 11+ warm-up program on explosive strength, speed, and perception of physical exertion in elite female futsal athletes. Twenty-nine elite female futsal athletes participating in the Italian national championships were divided into two groups: the experimental group (EG) underwent 5 weeks of the FIFA 11+ warm-up program, and the control group (CG) underwent 5 weeks of a dynamic warm-up. We evaluated any effect on explosiv…
Iekšzemes migrācijas un svārstmigrācijas ģeogrāfiskā struktūra un iezīmes apvienotajā Bauskas novadā
