Microsoft Word formāta pārskatu veidošana Lotus Notes lietotnei

2015

Lotus Notes lietotnē, kas paredzēta organizācijā reģistrēto projektu koordinēšanai, dati tiek eksportēti uz Microsoft Word dokumentiem. Eksportēti tiek arī dati no bagātinātā teksta laukiem, kuros var saglabāt formatētu tekstu, kā arī tabulas. Šobrīd lietotnē ir iespējams veidot Microsoft Word formāta pārskatus, taču šī funkcionalitāte strādā tikai datoriem, kuriem ir Windows operētājsistēma. Macintosh un Linux operētājsistēmu lietotājiem šī funkcionalitāte nestrādā. Darba mērķis ir izstrādāt analogu funkcionalitāti esošajai, kas darbosies arī citās operētājsistēmās, ne tikai Windows vidē. Lai to izdarītu, jāizpēta iespējamās alternatīvas un jāizvēlas piemērotākā no tām. Darba rezultātā ir …

Lumbriculus variegatus (Annelida) biological responses and sediment sequential extractions indicate ecotoxicity of lake sediments contaminated by bio…

2018

Abstract We assessed potential ecotoxicity of lake sediments affected by biomining effluents in northeastern Finland. Growth, reproduction and behavior of the sediment-dwelling oligochaete Lumbriculus variegatus (Muller 1774) were used as ecotoxicity endpoints. Standardized chronic bioassays were used for growth and reproduction, and acute and chronic tests with Multispecies Freshwater Biomonitor (MFB) for behavior assessments. Sequential extractions were used to characterize metal bioavailability and exposure conditions in the sediments, which indicated mining-induced contamination gradients of S, Cu, Ni and U and also bioavailability gradients of S and Ni. Among the ecotoxicity endpoints,…

Manganese overload affects p38 MAPK phosphorylation and metalloproteinase activity during sea urchin embryonic development.

2014

Abstract In the marine environment, manganese represents a potential emerging contaminant, resulting from an increased production of manganese-containing compounds. In earlier reports we found that the exposure of Paracentrotus lividus sea urchin embryos to manganese produced phenotypes with no skeleton. In addition, manganese interfered with calcium uptake, perturbed extracellular signal-regulated kinase (ERK) signaling, affected the expression of skeletogenic genes, and caused an increase of the hsc70 and hsc60 protein levels. Here, we extended our studies focusing on the temporal activation of the p38 mitogen-activated protein kinase (p38 MAPK) and the proteolytic activity of metalloprot…

Characterization of three different clusters of 18S-26S ribosomal DNA genes in the sea urchin P. lividus: Genetic and epigenetic regulation synchrono…

2015

We previously reported the characterization 5S ribosomal DNA (rDNA) clusters in the common sea urchin Paracentrotus lividus and demonstrated the presence of DNA methylation-dependent silencing of embryo specific 5S rDNA cluster in adult tissue. In this work, we show genetic and epigenetic characterization of 18S-26S rDNA clusters in this specie. The results indicate the presence of three different 18S-26S rDNA clusters with different Non-Transcribed Spacer (NTS) regions that have different chromosomal localizations. Moreover, we show that the two largest clusters are hyper-methylated in the promoter-containing NTS regions in adult tissues, as in the 5S rDNA. These findings demonstrate an an…

Phylogenetic position of two Macrobiotus species with a revisional note on Macrobiotus sottilei Pilato, Kiosya, Lisi & Sabella, 2012 (Tardigr…

2021

In a moss and lichen sample collected on the Polish coast, a new population of Macrobiotus sottilei was found. Given that the original description of M. sottilei was based solely on the morphology observed under light microscopy and measurements of a few individuals, we provide, by means of integrative taxonomy, a revisional note on this species. We present a comprehensive set of morphometric and morphological data from light and scanning electron microscopy analysis together with nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) DNA fragments. We also provide the same set of DNA sequences for Macrobiotus glebkai from a population recently found i…

Karyological and dental identification of Microtus limnophilus in a large focus of alveolar echinococcosis (Gansu, China).

1999

International audience; A study of voles (Arvicolidae, Rodentia) from Gansu (China) designed to identify a potential host of Echinococcus multilocularis, responsible for human alveolar echinococcosis, leads to a general analysis of Microtus limnophilus population karyotypes, M1 of M. oeconomus populations from all of Eurasia and of M. limnophilus of Mongolia. The Microtus of Gansu belonging to the nominal subspecies M. limnophilus limnophilus (2n = 38; NF = 58) differs markedly in size and shape of M1 from the M. limnophilus of Mongolia, which must therefore be considered as a new subspecies M. limnophilus of malygini nov. ssp. (2n = 38; NF = 60) and the M. oeconomus of Mongolia should be r…

Is there a linkage between metabolism and personality in small mammals? The root vole (Microtus oeconomus) example

2010

Significant inter-individual variation in the rate of animal metabolism is a widespread phenomenon that has started to accumulate general interest. Here we follow recent calls to focus on linkage between the variation in energy metabolism and animal personality. By using wild caught root voles as a study species, we examined the relationship between the behavioral patterns (assessed in open field test) and resting metabolic rate (RMR), both of which are known to show large individual differences and intra-individual consistency in voles. Our results showed only a weak relationship between personality traits and metabolism, since the most parsimonious model (according to AICc) explaining RMR…

Zizyphin modulates calcium signalling in human taste bud cells and fat taste perception in the mouse.

2017

Zizyphin, isolated from Zizyphus sps. leaf extracts, has been shown to modulate sugar taste perception, and the palatability of a sweet solution is increased by the addition of fatty acids. We, therefore, studied whether zizyphin also modulates fat taste perception. Zizyphin was purified from edible fruit of Zizyphus lotus L. Zizyphin induced increases in [Ca2+]i in human taste bud cells (hTBC). Zizyphin shared the endoplasmic reticulum Ca2+ pool and also recruited, in part, Ca2+ from extracellular environment via the opening of store-operated Ca2+ (SOC) channels. Zizyphin exerted additive actions on linoleic acid-induced increases in [Ca2+]i in these cells, indicating that zizyphin does no…
