Urban drinking and driving:comparison of electric scooter and bicycle related accidents in facial fracture patients
2022
In recent years, electric scooters (e-scooter) have emerged as an alternative mode of urban transport due to their availability and effortless use. However, e-scooter-related trauma and injuries, especially to the head, have received wide media coverage and raised public concern about their safety. We aim to determine and compare clinically relevant variables, incidence, and severity between bicycle and e-scooter-related facial fractures and potential protective measures for injury prevention. This retrospective study comprised all patients admitted to a tertiary trauma center with bicycle or e-scooter-related facial fractures between January 2019 and October 2020. Patient- and injury-relat…

Pharmacogenomic identification of small molecules for lineage specific manipulation of subventricular zone germinal activity
2017
Strategies for promoting neural regeneration are hindered by the difficulty of manipulating desired neural fates in the brain without complex genetic methods. The subventricular zone (SVZ) is the largest germinal zone of the forebrain and is responsible for the lifelong generation of interneuron subtypes and oligodendrocytes. Here, we have performed a bioinformatics analysis of the transcriptome of dorsal and lateral SVZ in early postnatal mice, including neural stem cells (NSCs) and their immediate progenies, which generate distinct neural lineages. We identified multiple signaling pathways that trigger distinct downstream transcriptional networks to regulate the diversity of neural cells …
Effect of different processing methods on the quality of obtained pomegranate juice
2019
Pomegranate juice has many health properties as the fruits contain anticarcinogenic, antimicrobial and antiviral compounds. Its consumption has greatly increased throughout the world in recent years due to the potential of its different components, polyphenols and anthocyanins mostly. Many studies have been performed on the pomegranate juice yield demonstrating its influence on the organoleptic and physicochemical properties of the juice. Commercial pomegranate juice production involves pressing the fruits. As a consequence, there is a need to investigate the pressing machine types and adjustment in order to maximize juice yield and enhance its health properties. The aim of this study was t…
Środowisko a antybiotykooporność izolatów Escherichia coli
2017
Pula farmaceutyków w środowisku powiększa się w wyniku kontaminacji wód, gruntów, ścieków, a także surowców pochodzenia zwierzęcego. Obecność antybiotyków w środowisku wpływa nie tylko na zahamowanie rozwoju mikroorganizmów, ale w stężeniu subinhibicyjnym może stymulować ekspresję genów wywołujących zjawisko antybiotykooporności. Celem pracy było porównanie wrażliwości na antybiotyki pałeczek Escherichia coli wyizolowanych z surowego mleka i zmieszanych odpadów drobiarskich. Materiał badawczy stanowiły szczepy E.coli wyizolowane z surowca mleczarskiego i zmieszanych odpadów drobiarskich. Ocenę wrażliwości izolatów na antybiotyki przeprowadzono metodą Kirby-Bauera. Profil oporności E. coli u…
Anticipated future of Latvia and Russia during a global economic crisis: A mixed methods perspective
2014
This cross-cultural study explored subjective predictors of more positive evaluation of the future of the country during a global socioeconomic crisis. A sequential mixed-method design was chosen for an exploration of students? expectations in Russia and Latvia as countries contrasting in macro-contextual conditions. In 2009, Study 1 was designed as a thematic analysis of essays on topic ?The Future of Latvia/Russia?. The results demonstrated that the future of a country is anticipated by taking into account external influences, the present of the country, and its perceived power and stability. In 2011, Study 2 involved these themes as independent variables in a multiple regression model. T…
Untargeted metabolomics of rind essential oils allowed to differentiate two closely related clementine varieties
2021
[EN] Chemical characterization of clementine varieties (Citrus clementina Hort. ex Tan.) essential oils (EO) can lead to variety identification and valorization of their potential use in food and aroma industries. The goal of this study was the chemometric discrimination between two very closely related and morphologically identical clementine varieties, Clemenules (NL) and Clemenpons (PO), based on their rind EO, to identify the differential volatile organic compounds (VOCs) and to determine their antioxidant capacity. EO rind volatile profile was determined by gas chromatography coupled to mass spectrometry in Citrus fruit at different ripening stages grown two independent years in two di…

Le score de propension : un guide méthodologique pour les recherches expérimentales et quasi expérimentales en éducation
2016
La méthode du score de propension devient de plus en plus populaire pour estimer les effets causaux d’un programme d’intervention. Si les applications empiriques de cette méthode sont encore rares dans les recherches en éducation, des exemples de son utilisation se trouvent aisément dans d’autres disciplines. Cependant, sa mise en place soulève plusieurs questions. L’objectif de cet article est de fournir des éléments de réponses guidant le chercheur et l’évaluateur du domaine de l’éducation pour l’estimation et l’utilisation du score de propension. Les différentes étapes de son application sont présentées pas à pas : évaluation du biais de sélection, construction du score de propension et …
