Abstract Bhargava, H. N., V. M. Villar, J. Cortijo and E. J. Morcillo. Binding of [3H][D-Ala2, MePhe4, Gly-ol5]enkephalin, [3H][D-Pen2, D-Pen5]enkephalin, and [3H]U-69,593 to airway and pulmonary tissues of normal and sensitized rats. Peptides 18(10) 1603–1608, 1997.—The role of endogenous opioid peptides in the regulation of bronchomotor tone, as well as in the pathophysiology of asthma is uncertain. We have studied the binding of highly selective [3H]labeled ligands of μ-([D-Ala2, MePhe4, Gly-ol5]enkephalin; DAMGO), δ ([D-Pen2, D-Pen5]enkephalin; DPDPE), and κ-(U-69,593) opioid receptors to membranes of trachea, main bronchus, lung parenchyma and pulmonary artery obtained from normal (uns…
Candida albicans ABG1 gene is involved in endocytosis.
2009
The human fungal pathogen Candida albicans undergoes reversible morphogenetic transitions between yeast, hyphal and pseudohyphal forms. The fungal vacuole actively participates in differentiation processes and plays a key role supporting hyphal growth. The ABG1 gene of C. albicans encodes an essential protein located in the vacuolar membranes of both yeast and hyphae. Using fluorescence microscopy of a green fluorescent protein-tagged version of Abg1p, a fraction of the protein was detected in hyphal tips, not associated with vacuolar membranes. Live cell imaging of emerging germ tubes showed that Abg1p migrated to the polarized growth site and colocalized with endocytic vesicles. Phenotypi…
Plazmas biomarķieru izmaiņas žurku akūtas mezenteriālas išēmijas modelī
2022
Lai gan akūtu mezenteriālu išēmiju (AMI) uzskata par retu slimību, tā ir ātri progresējoša un visbiežāk noved pie pacienta nāves. Neskatoties uz pēdējo gadu medicīnas sasniegumiem, agrīna un pareiza diagnoze vēl joprojām ir apgrūtinoša. Šobrīd klīnikā lietotie laboratorijas testi nav gana specifiski, tādēļ agrīna un jutīga biomarķiera izstrādei ir izšķiroša nozīme, lai glābtu pacientu dzīvības. Darba mērķis ir izpētīt trīs biomarķieru un kopējās antioksidantu spējas izmaiņas žurku plazmā pirmo divu stundu laikā kopš sākusies AMI. D- laktāta un zarnu taukskābes saistošā proteīna (I-FABP) koncentrācijas no išēmijas laika atkarīgā veidā pieauga, savukārt citrulīna līmenis samazinājās. Starp an…
Digital citizenship and the use of mobile devices in educational institutions
2018
Training in digital competence is one of the concerns in the educational sphere and, either at European, state and regional levels, policies have been developed for promote the responsible use of technologies in digital citizenship and, in particular, with minors and adolescents who live in a digital society. From Europe 2020 Strategy (European Commission, 2010), as well as the strategic framework: Education and Training 2020 (European Commission, 2009), it has been proposed a set of priorities that will be translated into national objectives for all member countries of the European Union, as a purpose for the year 2020. In this sense, following the European directives, in the Spanish conte…
Atgriezeniskās saites digitāli nodrošināšana attālinātā mācību procesā ķīmijā
2021
Atgriezeniskās saites nodrošināšana attālinātā mācību procesā digitāli. Kārlis Krastiņš, darba vadītāja: Mg. Chem. Ilze Gaile. Bakalaura darbs, 81 lpp, 27 literatūras avoti, 13 attēli, 4 tabulas, 5 pielikumi. Latviešu valodā. Darba mērķis ir izpētīt atgriezeniskās saites nodrošināšanas iespējas ķīmijas mācību stundās attālinātā mācību procesa ietvaros un, noskaidrot atgriezeniskās saites ietekmi uz skolēnu mācību sniegumu uzlabošanu. Literatūras analīze veikta par vērtēšanu, atgriezenisko saiti, IKT rīkiem, kurus iespējams izmantot, sniedzot atgriezenisko saiti skolēnam. Pētījuma empīriskajā daļā ir izveidots un aprobēts tematiskais plāns un stundu plāni, tajos iekļaujot atgriezeniskās sait…
Formatīvā vērtēšana digitāli bioloģijā un ģeogrāfijā
2019
Darba mērķis ir izpētīt formatīvās vērtēšanas (FV) digitāli izmantošanu bioloģijas un ģeogrāfijas mācību procesā. Literatūras analīze veikta par vērtēšanu, atgriezenisko saiti, IKT rīkiem un FV digitālajiem rīkiem bioloģijā, ģeogrāfijā. Empīriskajā daļā analizēti un aprobēti trīs FV digitālie rīki bioloģijā, ģeogrāfijā, izvērtēta skolotāju, skolēnu, vecāku attieksme digitālo rīku lietošanā. Pētījuma rezultāti pierāda, ka izmantotie FV digitālie rīki nodrošina jēgpilnu FV un kvalitatīvu atgriezenisko saiti bioloģijā un ģeogrāfijā.
Organic-Inorganic Hybrid Mesoporous Materials as Regenerable Sensing Systems for the Recognition of Nitroaromatic Explosives
2013
[EN] Fluorescent organic-inorganic mesoporous hybrid materials have been prepared and characterised, and their behaviour against nitroaromatic explosives have been tested. MCM-41 silica was used as an inorganic scaffold and pyrene (P derivative containing trialkoxysilane moieties), dansyl and fluorescein (D and F derivatives also containing trialkoxysilane groups, respectively) fluorophores have been anchored on hybrid materials by a co-condensation method to obtain a homogenous distribution of dyes into the pores of the support. Six sensing materials have been prepared, of which SP, SD, SF were hydrophilic and SPh, SDh, SFh were hydrophobic. Template-free hydrophilic materials (SP, SD, SF)…

Transmission of human immunodeficiency virus Type-1 by fresh-frozen plasma treated with methylene blue and light
2015
BACKGROUND The risk of transfusion-transmitted infection (TTI) has been minimized by introduction of nucleic acid testing (NAT) and pathogen inactivation (PI). This case report describes transmission of human immunodeficiency virus Type 1 (HIV-1) to two recipients despite these measures. STUDY DESIGN AND METHODS In March 2009 a possible TTI of HIV-1 was identified in a patient that had received pooled buffy coat platelet concentrate (BC-PLT) in November 2005. The subsequent lookback study found two more patients who had received methylene blue (MB)-treated fresh-frozen plasma (FFP) and red blood cells (RBCs) from the same donation. In November 2005 the donor had tested negative for both HIV…
