Čukstošās galerijas modu mikrorezonatoru modelēšana

2018

Dotajā darbā tiek aprakstīta teorija un modelēšanas rezultāti par gaismas izplatīšanos sfēriskos Čukstošās galerijas modu optiskajos mikrorezonatoros ar diametru 1 - 5 um. Modelēšanai tiek izmantota COMSOL Multiphysics datorprogramma ar viļņu optikas moduli (Wave Optics Module). Tiek apskatītas sistēmas prizma-rezonators un optiskā šķiedra-rezonators. Kā galvenie kontroles parametri tiek izmantotas elektriskā lauka Ez komponentes kartes un laikā vidējotā enerģijas blīvuma vērtība rezonatorā. 2D vidē tiek modelēts gaistošās gaismas lauks, rezonatorā esošā starojuma atkarība no gaismas krišanas leņķa prizmā, šķiedras platuma, rezonatora attāluma līdz prizmai/šķiedrai, rezonatora izmēra un krī…

Iekšējā kontrole nebanku kredītiestāde

2021

Diplomdarba tēma ir „Iekšējā kontrole nebanku kredītiestāde”. Pētījuma tēmas aktualitāte: uzņēmums X Rīgas filiāle darbojas finanšu produktu jomā, nav banka, bet izsniedz ātros kredītus, ir jānoskaidro trūkumi iekšējā vidē. Pētījuma objekts – uzņēmuma X Rīgas filiāles iekšējā kontrole. Pētījuma priekšmets – iekšējās kontroles elementi. Pētījuma tēmas aktualitāte: uzņēmuma X Rīgas filiālei, kura nav banka un darbojas finanšu produktu jomā, ir jānoskaidro trūkumi iekšējā vidē. Darbā tika izmantotā COSO modeļa pielietojums, kas parādīja, ka iekšējās kontroles sistēma kopumā atbilst COSO elementiem. Risku novērtēšanā ir daudz nepilnības. Uzņēmuma X Rīgas filiālei ir ieteicams vēl viens iekšējās…

Spectroscopic, crystal structural, theoretical and biological studies of phenylacetohydrazide Schiff base derivatives and their copper complexes

2020

Two phenylacetohydrazide Schiff base derivatives: N’-(1-(2-hydroxyphenyl)ethylidene)-2-phenylacetohydrazide, HL1, and N’-((1-hydroxynaphthalen-2-yl)methylene)-2-phenylacetohydrazide, HL2, were synthesized. HL1 dimerizes in presence of HCl, probably via radical mechanism to give (2,2’-((1E)-hydrazine-1,2-diylidenebis(ethan-1-yl-1-ylidene))diphenol (DIM). Thermal reactions of Cu(II) ions with the two Schiff base ligands resulted in formation of the binuclear complexes [(CuL1)2] and [(CuL2)2]. The stoichiometry and structures of the reported compounds were investigated by several spectroscopic and analytical techniques. The structure of the HL1 ligand and its complex [(CuL1)2] as well as the D…

Application of patient-derived liver cancer cells for phenotypic characterization and therapeutic target identification.

2018

Primary liver cancer (PLC) ranks among the most lethal solid cancers worldwide due to lack of effective biomarkers for early detection and limited treatment options in advanced stages. Development of primary culture models that closely recapitulate phenotypic and molecular diversities of PLC is urgently needed to improve the patient outcome. Long-term cultures of 7 primary liver cancer cell lines of hepatocellular and cholangiocellular origin were established using defined culture conditions. Morphological and histological characteristics of obtained cell lines and xenograft tumors were analyzed and compared to original tumors. Time course analyses of transcriptomic and genomic changes were…

Abstract 1690: Differential autophagy activation in KRAS and EGFR mutant lung adenocarcinomas.

2013

Abstract Lung cancer is the leading cause of cancer deaths in western countries, and adenocarcinomas (LADs) are the most frequent histological subtype. The aberrant activation of the kinases promotes plethora of tumorigenic processes, mainly through PI3K and MAPK oncogenic pathways leading to oncogene addiction. The activation of PI3K pathway deregulates mTOR, a master kinase for cell growth and autophagy. Autophagy can be pro- or anti- tumorigenic, however its roles in protecting tumors exposed to metabolic stress under chemotherapy are considered as a survival mechanism for the tumors leading to acquired resistance. Consequently, the inhibition of autophagy is an attractive therapy to pre…

2013

3551 Background: KRAS wt mCRC pts progressing on chemotherapy and anti-EGFR mAbs have limited treatment options. Sym004 is a first-in-class drug mixture of two mAbs targeting non-overlapping epitopes on the EGFR, causing its internalization and degradation. With this unique mechanism of action, Sym004 overcomes acquired resistance to anti-EGFR mAbs in preclinical studies. Methods: Open-label, multicenter trial assessing safety (primary endpoint) and efficacy of 2 dose levels of Sym004 in KRAS wt mCRC pts with prior clinical benefit to anti-EGFR mAbs and subsequent progression during or within 6 months after treatment cessation. Sym004 was administered until disease progression or unaccepta…
