Andrieva Niedras valdība 1919.gadā: izveide un personības
2021
Pētījums ir veltīts latviešu un Latvijas Neatkarības kara historiogrāfijā maz pētītām tēmām –Andrieva Niedras valdības darbībai un šīs valdības personībām. Bakalaura darba mērķis ir pētīt Andrieva Niedras valdības izveidi un personības, tādējādi konstatējot valdības dalībnieku ietekmi uz valdības darbību un tās īpatnībām, galvenokārt uzmanību veltot valdības sākumposmam. Ilgstoši saspringtās vācbaltiešu un latviešu etniskās attiecības izveidoja situāciju, kurā abām pusēm nav pieņemams otras puses valstiskums. Darba ietvaros aplūkota šo attiecību un nesaskaņu rezultātā izveidojusies valstiskuma alternatīva Latvijas Republikas Kārļa Ulmaņa vadītajai Pagaidu valdībai. Andrieva Niedras valdības…
Banku darbības attīstības raksturojums Latvijā
2018
Bakalaura darba tēma ir „Banku darbības attīstības raksturojums Latvijā”. Bakalaura darba tēmas aktualitāti pamato tas, ka mūsdienas finanšu tirgū ir lielā nozīme banku sistēmai un tās efektīvai darbībai. Darba mērķis ir izpētīt Latvijas banku sektora darbību un tā attīstības dinamiku, izpētot Latvijas banku sistēmas darbības vēsturi, analizējot banku darbības rezultātus un rādītājus. Papildus uzmanība ir pievērsta pēdējiem notikumiem saistītiem ar „ABLV Bank” pašlikvidācijas Latvijas Banku sektorā. Autores iegūtie rezultāti liecina par to, ka Latvijas banku sektora darbības rezultāti uzlabojas uz stabilizējas pēc pasaules finanšu krīzes, bet ņemot vērā pēdējos notikumus banku sektorā, situ…
Absence of long-term effects of reproduction on longevity in the mouse model.
2014
Background Most human demographic data, particularly those on natural fertility populations, find no relationship or even a positive association between fertility and longevity. The present study aims to ascertain whether there is a trade-off between fertility and longevity in the mouse model. Methods The study was focused on the first litter produced by 10- to 14-wk-old hybrid (C57BL/6JIco female X CBA/JIco male) mice. A single female/male per litter was individually housed with a male/female at the age of 25 and 52 wk, respectively, until the end of reproductive life in females or natural death in males under controlled housing conditions. Post-reproductive females and virgin mice were re…

Xid-defective male (CBA/N x C57BL/6)F1 accessory cells present bovine insulin to long-term cultured F1-restricted T-cells
1982
The reactivity of H-2b-restricted murine T cells towards bovine insulin was reported to depend on the expression of Ia. W39, a private specificity of I-Ab, on antigen-presenting cells. Cells of male (CBA/N X B6)F1 mice carrying the mutation xid on the X chromosome lack IA. W39 on the cell surface. These cells are unable to present bovine insulin to primed T cells derived from female (CBA/N X B6)F1 mice. We show here that spleen cells of male (CBA/N X B6)F1 hybrids served perfectly as accessory cells for the insulin-dependent induction of a proliferative response of long-term cultured T cells with (B10 X B10.BR)F1 genotype, restricted to recognizing insulin in the context of F1-unique I-A de…
Three cell subsets are required for the transfer of delayed-type hypersensitivity reaction by antigen-specific T cell lines.
1997
Antigen (trinitrochlorobenzene)-specific T cell lines were obtained by repeated stimulation of lymph node cells from immune mice with antigen in vitro. These T cell lines, consisting of more than 90% CD4+ Vbeta8.2+ and 6 to 9% gammadelta+ T lymphocytes, transfer contact sensitivity (CS) locally when injected at the same site as the challenge antigen, but fail to mediate a systemic passive transfer when injected i.v. Injection of T cell lines together with spleen cells from mice immunized 1 day beforehand (1-day cells) allowed a successful, specific systemic transfer of CS. Phenotypic analysis showed that the 1-day immune cell was alphabeta+, gammadelta-, sIg-, CD3+, CD4-, CD8-, CD5+, B220 (…
Beneficial effects of dithiothreitol on relative levels of glutathione S-transferase activity and thiols in oocytes, and cell number, DNA fragmentati…
2006
We analyzed the effect of in vitro aging of mouse oocytes in the presence of dithiothreitol (DTT) on relative levels of glutathione S-transferase (GST) activity and thiols in oocytes, and cell number, DNA fragmentation and cellular allocation to the inner cell mass (ICM) and trophectoderm (TE) lineage at the blastocyst stage. Ovulated oocytes from gonadotropin primed hybrid female mice of 6-8 weeks of age were aged in vitro in the presence of 0, 5, 50, or 500 microM DTT for 6 hr prior to insemination. Relative levels of GST activity and thiols in oocytes were determined by confocal laser scanning microscopy, DNA fragmentation using a single-step TUNEL method, and cell allocation to the ICM …
Comparative pharmacological activity of optical isomers of phenibut
2007
Phenibut (3-phenyl-4-aminobutyric acid) is a GABA (gamma-aminobutyric acid)-mimetic psychotropic drug which is clinically used in its racemic form. The aim of the present study was to compare the effects of racemic phenibut and its optical isomers in pharmacological tests and GABAB receptor binding studies. In pharmacological tests of locomotor activity, antidepressant and pain effects, S-phenibut was inactive in doses up to 500 mg/kg. In contrast, R-phenibut turned out to be two times more potent than racemic phenibut in most of the tests. In the forced swimming test, at a dose of 100 mg/kg only R-phenibut significantly decreased immobility time. Both R-phenibut and racemic phenibut showed…
