Transcriptomic Analysis of the Pistacia vera (L.) Fruits Enable the Identification of Genes and Hormone-Related Gene Linked to Inflorescence Bud Absc…
2021
Pistacia vera (L.) is an alternate bearing species. The tree produces axillary inflorescence buds every year. Still, they abscise in “ON” overloaded shoots, causing a limited production in the following “OFF” year, causing a significant and unfavorable production fluctuation. In this work, we carried out de novo discovery and transcriptomic analysis in fruits of “ON” and “OFF” shoots of the cultivar Bianca. We also investigated whether the fruit signaling pathway and hormone biosynthesis directly or indirectly linked to the premature fall of the inflorescence buds causing alternate bearing. We identified 1536 differentially expressed genes (DE…
The Innervation of Taste Buds in the Soft Palate of the Rat as Revealed by Methylene Blue Staining.
1996
Light microscopic data on the innervation of taste buds in the soft palate of the rat obtained by methylene blue (MB) supravital staining are presented here for the first time. The taste pore including subpopulations of taste bud cells and nerve fibers were stained. Intragemmal nerve fibers were detected ascending up to the taste pore; this suggests the possibility of additional paracellular pathways in taste transduction directly via nerve fibers. Moreover, relatively large bulbous or laminar enlargements of the intragemmal nerve fibers were found. The branches of these nerve fibers, showing minute spiny protuberances, appeared to anastomose. Some perigemmal nerve fibers were also seen in …
Developmental morphology of Apinagia multibranchiata (Podostemaceae) from the Venezuelan Guyanas
2000
Abstract Apinagia ( c. 50 spp.) is the largest genus of American Podostemaceae. Apinagia multibranchiata (Matth.) Royen is a haptophyte endemic to the Venezuelan Guyanas. It fits well with the Podostemoideae bauplan known from other New World genera, such as Marathrum and Mourera . Shoots arise in pairs from filamentous creeping adhesive roots. During the rainy season submerged vegetative shoots grow up to more than a metre long. They are normally unbranched and provided with distichously arranged leaves which are laterally flattened into one plane. The lanceolate leaves may show a fimbriate tip. Tufts of threads are found on the upper leaf surface which faces the sky. When the water recede…

2017
Maģistra darba tēma ir Valsts budžeta pieņemšanas atspoguļojums Latvijas Radio raidījumos „Krustpunktā”, „Pusdiena” un „Dienas notikumu apskats”. Darbā ir aplūkots 2017. gada valsts budžeta atspoguļojums sabiedriskā medija – Latvijas Radio, politiski analītiskajos raidījumos, un noskaidrotas koncepta „mediji – politika – sabiedrība” savstarpējā mijiedarbība un katra koncepta elementa ietekme vienam uz otru, pielietojot mediatizācijas teoriju. Metodoloģijā ir izmantotas divas pētniecības metodes: kvalitatīvā kontentanalīze un daļēji strukturēta intervija. Rezultātā ir iegūtas atbildes uz darba pētniecības jautājumiem, kā arī ir iezīmētas būtiskākās problēmas Latvijas mediju, sabiedrības un p…
Jelgavas pilsētas pašvaldības darbības izvērtējums un attīstības perspektīvas
2016
Bakalaura darba tēma ir: „Jelgavas pilsētas pašvaldības darbības izvērtējums un attīstības perspektīvas”, darbā tiek pētīta jelgavas pašvaldības darbība kas saistīta ar budžeta līdzekļu apguvi pret to sākotnējo ieceri analizējot cik sekmīgi tā ir noritējusi. Pētījuma mērķis ir uz pieejamās informācijas pamata analizēt Jelgavas pilsētas pašvaldības darbību, izvērtējot tās darbības efektivitāti, kā arī tās ilgtermiņa attīstības ieceres, izvīrzītais izpētes jautājums ir: vai Jelgavas pilsētas pašvaldības darbību kopums, kas saistīts ar pilsētas attīstību laika posmā no 2012. līdz 2014. gadam ir uzskatāms par pietiekami sekmīgu, lai uz tā pamata varētu balstīt savus attīstības scenārijus.

“Mitotic Slippage” and Extranuclear DNA in Cancer Chemoresistance: A Focus on Telomeres
2020
Mitotic slippage (MS), the incomplete mitosis that results in a doubled genome in interphase, is a typical response of TP53-mutant tumors resistant to genotoxic therapy. These polyploidized cells display premature senescence and sort the damaged DNA into the cytoplasm. In this study, we explored MS in the MDA-MB-231 cell line treated with doxorubicin (DOX). We found selective release into the cytoplasm of telomere fragments enriched in telomerase reverse transcriptase (hTERT), telomere capping protein TRF2, and DNA double-strand breaks marked by γH2AX, in association with ubiquitin-binding protein SQSTM1/p62. This occurs along with the alternative lengthening of telomeres (ALT) and DNA repa…
Ks. Konstantego Damrota opowieść o polskim Pomorzu (na podstawie Szkiców z ziemi i historyi Prus Królewskich z 1886 r.)
2022
Jedną z ważnych postaci Kościoła katolickiego na Pomorzu był ks. Konstanty Damrot (1841–1895) – syn śląskiej ziemi, wybitny literat, wieloletni dyrektor katolickiego seminarium nauczycielskiego w Kościerzynie. Zachwycony pięknem dawnych Prus Królewskich, w 1886 r. wydał pozycję książkową zatytułowaną Szkice z ziemi i historyi Prus Królewskich, Jego zamiarem było nie tylko opisanie piękna nadmorskiej krainy, ale przede wszystkim obudzenie ducha polskiego w tamtejszych mieszkańcach. Poprzez słowo pisane chciał także spopularyzować historię i kulturę nadmorskiej krainy, przesiąkniętej polskością, zbudowaną na wierze katolickiej i rodzimej tradycji. Autor w krótkiej syntezie przedstawia biogram…
Power system consumption model using SPICE
2014
Space missions have very stringent mass, volume and also power budgets. This requires very precise knowledge of the power consumption of the whole satellite, not only peak power but also static and long term dynamic power. This calculation becomes very complex if all the operational modes (long term dynamic changes) are taken into account, including the different environmental situations. The power budget of any Power Converter Module (PCM), which includes not only the DC/DC converter but also the distribution unit, depends on the power it delivers and on external factors like temperature and input voltage. We propose to use a linear SPICE model using electronic models of discrete component…
The Wnt-specific astacin proteinase HAS-7 restricts head organizer formation in Hydra
2021
Abstract Background The Hydra head organizer acts as a signaling center that initiates and maintains the primary body axis in steady state polyps and during budding or regeneration. Wnt/beta-Catenin signaling functions as a primary cue controlling this process, but how Wnt ligand activity is locally restricted at the protein level is poorly understood. Here we report a proteomic analysis of Hydra head tissue leading to the identification of an astacin family proteinase as a Wnt processing factor. Results Hydra astacin-7 (HAS-7) is expressed from gland cells as an apical-distal gradient in the body column, peaking close beneath the tentacle zone. HAS-7 siRNA knockdown abrogates HyWnt3 proteo…
