"Zasiewający we łzach, w radości żąć będą" (Ps 126,5). Motywy radości w Psałterzu na przykładzie Psalmu 126
2016
Joy is one of the basic human feelings that express emotional, psychological, and spiritual state. Thus the biblical books and especially the Book of Psalms show various motifs of joy among numerous existential situations. Not only joy is the characteristic but its distinct reference to the relation with God as the One who is the source of joy even in the midst of worries and trials. It is exemplified by Psalm 126 which presents the motifs of joy included in the experience of sowing and harvesting. These motifs were raised accurately and meaningfully in the description of the situation of changing man’s lot from the state of sadness, caused by suffering, to joy and happiness of new life.
Morphological alterations in the hippocampus of the Ts65Dn mouse model for Down syndrome correlate with structural plasticity markers
2018
Down syndrome (DS) is the most common chromosomal aneuploidy. Although trisomy on chromosome 21 can display variable phenotypes, there is a common feature among all DS individuals: the presence of intellectual disability. This condition is partially attributed to abnormalities found in the hippocampus of individuals with DS and in the murine model for DS, Ts65Dn. To check if all hippocampal areas were equally affected in 4-5 month adult Ts65Dn mice, we analysed the morphology of dentate gyrus granule cells and cornu ammonis pyramidal neurons using Sholl method on Golgi-Cox impregnated neurons. Structural plasticity has been analysed using immunohistochemistry for plasticity molecules follow…
TRPV1 channels in nitric oxide-mediated signalling: insight on excitatory transmission in rat CA1 pyramidal neurons
2022
Nitric oxide (NO) is a fascinating signalling molecule implicated in a plethora of biological functions, especially at the synaptic level. Exploring neurotransmission in the hippocampus could be instrumental in the individuation of putative targets for nitric-oxide mediated neuromodulation, especially in terms of the potential repercussions on fundamental processes i.e. synaptic plasticity and excitability-related phenomena. Among these targets, endovanilloid signalling constitutes an object of study since Transient Receptors Vanilloid type 1 (TRPV1) channels possess a NO-sensitive gate modulating its activation. Also, NO has been referred to as a mediator for numerous endocannabinoid effec…
INDAGINI SULLA RISPOSTA IMMUNITARIA DEL PUNTERUOLO ROSSO NEI CONFRONTI DEI NEMATODI ENTOMOPAGENI
2009
Il Punteruolo rosso delle palme (Rhynchophorus ferrugineus Olivier, 1790. Coleoptera Curculionidae), originario dell’Asia meridionale si è velocemente diff uso nell’areale mediterraneo attaccando diversi generi di palme e creando seri problemi al settore ornamentale e vivaistico, oltre che alle aree verdi delle città. Il controllo di questo fi tofago si è rivelato problematico e di diffi cile realizzazione a causa delle sue proprietà invasive. Allo stato attuale non sono stati individuati patogeni effi caci nella lotta biologica, anche se i nematodi entomopatogeni (EPN) sono stati impiegati con discreto successo in Spagna. Generalmente gli EPN sono impiegati contro gli stadi larvali ma poic…
Bioloģiskie darba vides riski atkritumu apsaimniekošanas nozarē un šo risku darba aizsardzības vadības sistēmas pilnveidošana
2015
Darba nosaukums: “Bioloģiskie darba vides riski atkritumu apsaimniekošanas nozarē un šo risku darba aizsardzības vadības sistēmas pilnveidošana”. Darba autore: Elīna Saulīte. Darba zinātniskais vadītājs: Dr.ķīm., asoc. prof. Andris Alfrēds Spricis. Darbs izklāstīts uz 91 lpp., ietver 25 attēlus, 6 tabulas, 38 informatīvos avotus. Pētījums sastāv no 3 daļām. Pirmajā nodaļā apkopota un analizēta literatūra par atkritumu apsaimniekošanas nozari, kā arī tajā esošie darba vides riska veidi, kas var radīt negatīvu ietekmi uz nodarbināto veselību un darba kapacitāti. Otrajā nodaļā veikta akadēmiskās un zinātniskās literatūras analīze ar mērķi izprast un iegūt vispārēju priekšstatu par bioloģisko r…
Latvijas robežsardzes izveidošanās Neatkarības kara un pēckara laikā (1919.-1922.g.)
2020
Darbs veltīts historiogrāfijā maz pētītai tēmai - Latvijas robežsardzes izveidei un pirmajiem darbības gadiem. Bakalaura darba mērķis ir izpētīt Latvijas Republikas robežsardzes un robežapsardzības sistēmas izveidošanos, Neatkarības kara un pirmo pēckara gadu laikā, pastiprinātu uzmanību pievēršot organizācijai, vadībai, kā arī svarīgākajiem notikumiem, pārmaiņām un darbībai. Robežsardze bija viena no vitālākajām institūcijām, ko vajadzēja izveidot, valstij pārejot uz miera laika stāvoklī. Robežapsardzības sistēma pakāpeniski nomainīja armijas vienības un aizstāja frontes līniju ar pārbraucamu robežu. Darbs, ko veica robežsardze bija nozīmīgs daudzos militāros, politiskos un ekonomiskos pro…
A Hierarchy of Twofold Resource Allocation Automata Supporting Optimal Sampling
2009
We consider the problem of allocating limited sampling resources in a "real-time" manner with the purpose of estimating multiple binomial proportions. More specifically, the user is presented with `n ' sets of data points, S 1 , S 2 , ..., S n , where the set S i has N i points drawn from two classes {*** 1 , *** 2 }. A random sample in set S i belongs to *** 1 with probability u i and to *** 2 with probability 1 *** u i , with {u i }. i = 1, 2, ...n , being the quantities to be learnt. The problem is both interesting and non-trivial because while both n and each N i are large, the number of samples that can be drawn is bounded by a constant, c . We solve the problem by first modelling it a…

Protective Effect of Astaxanthin on Primary Retinal Cells of the Gerbil Psammomys Obesus Cultured in Diabetic Milieu
2017
Astaxanthin is a major marine carotenoid with powerful antioxidant and neuroprotective properties. The in vitro protective effect of astaxanthin in adult retinal cells of the type-2 diabetic model Psammomys obesus in hyperglycemic conditions was investigated. Primary retinal cells were cultured in normal (5 mM) or high concentrations of glucose (25 and 40 mM) for 5 days and treated with 1-20 μM astaxanthin for the last 48 h of culturing. Mitochondrial dehydrogenase activity and cell viability were assessed using MTT test and trypan blue exclusion dye. Retinal cells were characterized by immunohistochemistry. The results showed that mitochondrial function increased significantly (P<0.05) …
Seed germination reports for coastal sand dune species from Sicily
2019
This study investigated seed germination in nine psammophilous species occurring in Sicilian sand dunes, some of which, such as Muscari gussonei, Launaea resedifolia and Pancratium maritimum, are endemic and/or rare and very scattered in the area. Different germination protocols were tested for one or more populations and the best germination results per species are provided, reporting experimental conditions and specific comments on the germination behaviour.
