Holskābes un tās atvasinājumu solvātu veidošanās un desolvatācijas mehānisms
2015
Holskābes un tās atvasinājumu solvātu veidošanās un desolvatācijas mehānisms. Zvaniņa D., darba vadītāji prof. Actiņš A., Mg.Chem. Bērziņs A. Maģistra darbs, 60 lappuses, 27 attēli, 6 tabulas, 47 literatūras avoti, 3 pielikumi. Latviešu valodā. Darbā tika pagatavots holskābes metilestera dimetilformamīda solvāts un, kristalizējot holskābes metilesteri no izo-propanola, n-propanola un izo-butilspirta, iegūta holskābes metilestera I polimorfā forma. Kristalizējot holskābi, henodeoksiholskābi un ursodeoksiholskābi no dažādiem organiskajiem šķīdinātājiem, tika iegūti holskābes etanola, metanola un acetonitrila solvāti un henodeoksiholskābes nitrometāna solvāts. Iegūtās cietās fāzes tika pārbaud…
Detección inmunohistoquímica de la proteína L1 de Virus Papiloma Humano (HPV) de alto riesgo en citologías y biopsias de cuello uterino
2005
Para confirmar la detección inmunohistoquímica de la proteína L1 de HPV de alto riesgo, tanto en citologías con anormalidades en células epiteliales como en biopsias con diagnóstico de carcinoma epidermoide cervical, se seleccionaron aleatoriamente: 11 citologías cervicales del año 2004 con interpretación citológica de anormalidades en células escamosas incluyendo: células escamosas atípicas y lesión intraepitelial escamosa de bajo y alto grado y 50 biopsias de cérvix con carcinoma epidermoide diagnosticados entre los años 1950 y 1980. Todas las muestras, tanto citológicas como histológicas fueron sometidas al procedimiento inmunohistoquímico para la detección de la proteína L1 de HPV de al…
Electrochemical processes in macro and microfluidic cells for the abatement of chloroacetic acid from water
2014
Abstract The remediation of solutions contaminated with monochloroacetic acid (CAA), which is one of the most resistant haloacetic acids (HAAs) to chemical degradation, dramatically depends on the adopted electrochemical approach: (i) CAA is only poorly oxidized either by homogeneous hydroxyl radical in electro-Fenton (EF), electrogenerated active chlorine or electro-oxidation on Pt anode; (ii) it is moderately abated by direct reduction on silver or compact graphite cathodes (from 30% in macro cells to 60% in the microfluidic devices); (iii) it is quantitatively removed by direct electro-oxidation on a boron-doped diamond (BDD) anode. The use of a microreactor enables operation in the abse…
Synthesis of iodobiaryls and dibenzofurans by direct coupling at BDD anodes.
2014
The first direct oxidative phenol-arene cross-coupling reactions of an iodine-containing guaiacol derivative and the possible over-oxidation products of electron-rich phenols are described. Hereby, a "green" and targeted synthesis for dibenzofurans was developed.
Pacientu pārvešanas standartizācija no kardioķirurģijas zāles uz bērnu intensīvās terapijas nodaļu
2019
Maģistra darba tēma – Pacientu pārvešanas standartizācija no kardioķirurģijas zāles uz bērnu intensīvās terapijas nodaļu. Maģistra darba tēmas aktualitāti nosaka standartizētas pacientu transportēšanas pieejas pielietošana bērnu stacionārā, pacientu drošības uzlabošanai un pārvešanas procesa strukturēšanai. Darba mērķis ir izveidot un ieviest protokolu, kas uzlabotu un standartizētu pārvešanas procesu no kardioķirurģijas operāciju zāles uz bērnu intensīvās terapijas nodaļu. Pētījumā tika apkopota un analizēta literatūra par pacienta transportēšanas, pārņemšanas un nodošanas praksi pasaulē un stacionārā un analizētas Nolas Pender, Dorotejas Oremas māszinību teorijas. Pētījuma dizains veidots…
Herbalists, traditional healers and pharmacists: a view of the tuberculosis in Ghana
2014
This paper is the result of a visit by Brazilian researchers to Ghana, with the aim of improving understanding of the relationship between traditional healers and conventional health practices, specifically in relation to tuberculosis. Through this exploratory visit, this group of researchers promoted by the Edital Pro Africa (CNPq) had an opportunity to learn about, reflect on, and discuss the different social, economic and cultural realities and contexts that have led to the different health conditions and forms of healthcare in Ghana. Besides the direct relationship between the social and economic conditions of the country and the health of its population, it was also concluded that ther…
Death of a 23-year-old man from cardiac conduction system injury through a blunt chest impact after a car accident.
2014
Abstract Cardiac contusion, usually caused by blunt chest trauma, has been recognized with increased frequency over the past decades. Traffic accidents are the most frequent causes of cardiac contusion resulting from a direct blow to the chest. Myocardial contusion is difficult to diagnose; the clinical presentation varies greatly, ranging from a lack of symptoms to cardiogenic shock and arrhythmia. Although death is rare, cardiac contusion can be fatal. The authors report a case of death due to a cardiac conduction system injury from a blunt chest impact following a car accident. The autopsy showed no external signs of thoracic trauma, no evident rib or sternum fractures. A small sub-endoc…

Immune activation promotes evolutionary conservation of T-cell epitopes in HIV-1.
2013
The immune system should constitute a strong selective pressure promoting viral genetic diversity and evolution. However, HIV shows lower sequence variability at T-cell epitopes than elsewhere in the genome, in contrast with other human RNA viruses. Here, we propose that epitope conservation is a consequence of the particular interactions established between HIV and the immune system. On one hand, epitope recognition triggers an anti-HIV response mediated by cytotoxic T-lymphocytes (CTLs), but on the other hand, activation of CD4(+) helper T lymphocytes (TH cells) promotes HIV replication. Mathematical modeling of these opposite selective forces revealed that selection at the intrapatient l…
