Vascular progenitor cells in arterial remodeling
No full textCardiovascular disease is the leading cause of global mortality and physical disability mainly due to the complications such as myocardial infarction or stroke. Physiological healing reaction takes place in the diseased vessel wall aimed to repair the vessel after an injury. There are two factors essentially important for clinical improvement of vascular diseases. The first one is protection of the vascular damage, and the second one is repair of injured, ischemic and regenerating tissues to restore and maintain their function. The existing paradigm states that vascular progenitor cells are found in the vasculature and contribute to repair of injured blood vessel. However, the mechanism underlying the integration of these cells into the vasculature, their origin and specific functions has been unclear. This thesis presents a new understanding to this concept. Using human cardiac biopsies and animals models of arterial injury, we investigated whether progenitor cells can affect arterial repair and which mechanisms could be responsible for their action. Indeed, we have shown that adult vascular progenitor cells exist and possess a potential that extends beyond the cell types of their resident tissue. The vascular progenitor cells can be recruited either from bone marrow or blood vessel tissue in response to inflammation and migrate towards the sites of injury. Although, these cells are able to inhibit intimal hyperplasia, their contribution to formation of intimal lesion is not equal.We provide evidence that inflammation and monocyte chemoattractant protein 1 (MCP-1) are pivotal in the recruitment of recipient-derived cells of smooth muscle cell phenotype into arterioles of transplanted human hearts. The number of these cells in the arterioles correlated strongly with the number of CD45-positive leukocytes and the grade of rejection, confirming that inflammation is strongly related to the recruitment of circulating progenitor cells into the graft vessels. This knowledge may be useful to design protocols for increase of progenitor cell numbers to limit tissue damage and facilitate healing at sites of tissue injury.In our hands, bone marrow-derived cells, which are known source of stem cells and their progenitors, supported early stages of arterial injury and thereafter were eliminated from the artery wall. These cells localized in the arterial intima and the majority of them were of endothelial phenotype. Furthermore, bone marrow-derived cells were not able to fuse however could differentiate into vascular cells to adjust in the vessel wall and meet the demands and needs of their new microenvironment. Interestingly, local delivery of bone marrow-derived endothelial cells to the sites of arterial injury resulted in decrease of the intimal lesion area. Taken together, our results indicate the importance of these cells in the inhibition of early stages of intimal formation.Further, we showed that enhanced inflammation in rat arterial allograft by acute infection with Cytomegalovirus (CMV) led to enhanced local MCP-1 production in the vasculature. Interestingly, CMV potentiated inflammation mainly in the adventitia, which resulted in migration of adventitial cells towards the intima and more rapid and severe intimal hyperplasia. Our findings increase understanding of the role of pathogens, such as CMV, in vascular remodeling and highlight that adventitial cells are able to migrate in vivo towards the sites of arterial injury, most likely in response to MCP-1.We identified mesenchymal tissue-derived progenitor cells in vascular adventitia (Sca-1/CCR2, c-kit/CCR2) that contributed to vascular remodeling in a rat model of transplant vasculopathy. Early proliferation of cells in the adventitia coincided with an increase in the number of apoptotic cells in the media, and both proliferation and apoptosis were associated with inflammation. Inflammation and MCP-1 production were pivotal in the migration of mesenchymal progenitor cells derived from adventitia towards the intima.In summary, this thesis presents novel evidence showing that inflammation and MCP-1 are important for recruitment of vascular progenitor cells to the sites of arterial injury and suggests tissue-derived mesenchymal progenitor cells, here from arterial adventitia, as a key source of cells for vascular repair. We believe that knowledge presented here not only increases understanding of vascular pathology but also provides unique value for understanding of unraveled aspects of tissue repair process.List of scientific papersI.

The influence of betaine on the productivity and physiological processes of broiler chickens.
No full textAuthor of the thesis: Monika Šidlauskaitė Research topic. The influence of betaine on the productivity and physiological processes of broiler chickens. Aim - to analyse the influence of betaine on the productivity and physiological processes of broiler chickens. Research methods. The experiment was started with 1000 broiler chickens, which were divided into 4 gr. The broiler chickens in the control gr. were fed standard compound feeds and the test gr. were fed with the appropriate amount of betaine added: test gr. I - 1 kg, test gr. II - 2 kg, test gr. III - 3 kg. During the experiment, the productivity and digestive processes of broiler chickens were studied (pH of the intestinal contents (pH meter “Inolab 730”), SM (determined as the difference between the wet and dry sample after drying at 105 °C for 3 hours), ammoniacal nitrogen content (“Foss-Tecator” ASN 3302 method), intestinal contents and visceral development (weighing with KERN PBS/PBJ scales and measuring with “Hoechstmass” flexible centimeter tape)). Results. The weights and daily weight gain of broiler chickens in the study gr. were only 1 precent higher (p>0.05) and feed consumption per kg of body weight over the test period in the study gr. was 6, 9, and 11 percent respectively (p0.05). The heart weights of the broiler chickens in the study gr. were 0.03 g, 1.5 g and 0.71 g, respectively, the liver weight was 1.38 g, 12.09 g and 5.58 g, and the pancreatic weight was 1.72 g, 1.97 g and 1.86 g and betaine under the influence of 2 and 3 kg/t feed - muscle stomach and fat-free muscle weight (2.56 g and 2.21 g), also intestinal length 21 cm and 27.2 cm, intestinal weight with contents 15.58 g and 10.26 g and intestinal weight without contents 4.96 g and 9.74 g, decreased compared to the control gr. (p>0.05). No statistically significant effect of betaine on intestinal pH was found. It was found that the addition of betaine to the feed caused a higher accumulation of dry matter in the gastrointestinal tract of broiler chickens of the study gr. (p>0.05). The reduction in ammonia nitrogen was found only in the first study gr. and amounted to 39.36 mg/percent (p>0.05) compared to the control gr. The scope of the thesis. 40 pages, 11 tables and 3 figures
Risk - adjusted rates of return for project appraisal
No full textIncorporating risk assessment into public project appraisal makes sense when project risk is significantly correlated with uncertainty about national income. It is especially important in countries that specialize in particular agricultural or resource sectors. This report presents the following conclusions: (a) risk corrections can be substantial; (b) the intuition that risk is great for further investment in a crop or sector that constitutes a large part of a country's GNP is not invalid, but the effect may be offset by other forces in operation; (c) risk corrections can be negative because of a negative correlation between project return and GNP; (d) risk premia vary greatly across countries and sectors - so recognizing the risk correction needed for each project on its own merits makes more sense than including a common general risk premium in the rate of return required for all lending; (e) risk corrections are small for many sectors and countries - so efforts can be concentrated on the other categories, where the proposed treatment of risk makes a big difference; (f) risk affects investment projects in many different, subtle ways; and (g) resource requirements for this are not great.Environmental Economics&Policies,Health Economics&Finance,Banks&Banking Reform,Statistical&Mathematical Sciences,Crops&Crop Management Systems
Possibilities of preventing aggressive behavior of children in middle preschool age
No full textDarba autore: Eva Monika Švarca Darba temats: Bērnu agresīvas uzvedības novēršanas iespējas vidējā pirmsskolas vecumposmā. Darbs sastāv no ievada, 2 daļām, secinājumiem un pielikumiem. Atslēgas vārdi: agresija, bērna attīstība, metodes ar kuru palīdzību tiek novērsta agresija. Darba teorētiskajā daļā tika analizētas dažādu autoru atziņas par agresiju tās izpausmēm un ietekmējošiem faktoriem. Vecākā pirmsskolas vecuma bērnu attīstību, sociālo faktoru ietekme uz pētāmo bērnu un metodes ar kuru palīdzību iespējams novērst agresīvu uzvedību. Bērna emocionalitāte, pašregulācija, vēlmei būt uzklausītam ir kā priekšnoteikums bērna psihiskai un fiziskai attīstībai, par to raksta A. Ļeontjeva, G. Svence, D. Lieģiniece, A. Špona un citi autori. Bērna ikdiena nav iedomājama bez socializēšanās. Tieši socializējoties bērns izzina sevi, savas vajadzības un vēlmes. Iemācās pieņemt otra teikto un darīto. Veido likumsakarības, izvērtē pretrunas ar kurām saskaras. Apzinās savas rīcības sekas un visbeidzot redz sevi, kā kopienas daļu. To uzsver Rean, Škuškovina, Schulz von Thunss F. un citi autori. Darba praktiskajā daļā tika pētīts vecākā pirmsskolas vecuma bērnu agresīvas uzvedības novēršanas iespējas: izvirzīti agresīvas izpausmes kritēriji pētījuma sākumā un beigās, izmantoja nepārtraukto novērošanas metodi, bērnu rīcības analīze, izvēlētas metodes pirmsskolas vecuma bērnu agresīvas uzvedības novēršanai, tika veikta atkārtota bērnu agresīvas uzvedības novēršanas iespēju izvērtēšana izmantojot iepriekš izmantotos kritērijus. Darba autore bērnu agresīvas uzvedības novēršanai izmantoja mācību materiālus, vides maiņu, atbalsta personāla atbalstu. Metožu pamatā ir sociālās spēles, situācijas modelēšana, kas tiek veidotas, lai radītu iespēju atkārtoti saskatīt darbības/rīcības pozitīvās un negatīvās sekas. Vides maiņa liek mainīties emocionālam stāvoklim, kas samazina rīkoties agresīvi. Minēto kopumu izmantošana dod pozitīvu ietekmi uz bērna paškontroles stiprināšanu un izvairīšanos no agresīvas uzvedības izpausmēm. Darbs sastāv no 61 lapaspusēm, 2 attēli, 5 tabulām, tam ir pievienoti 5 pielikumi. Darbā izmantoti 32 literatūras un informācijas avoti no kuriem 24 latviešu valodā un 8 svešvalodā.Anotation The author of the thesis: Eva Monika Švarca The topic of the thesis: Possibilities of preventing aggressive behavior of children in middle preschool age. The thesis consists of the introduction, 2 parts, conclusion and the aappendices. The key words: aggression, child development, methods by wich aggression is prevented. In the theoretical part were analyzed findings of various authors on aggression and its expression and influencing factors. The development of older preschool children, the social factor on the child and the methods by which it is possible to prevent aggressive behavior. Acording to A. Leontjeva, G. Svence, D.Lieginiece, A. Spona and other authors the child’s emotionality, self-regulation, the disire to be heard is a precondition for the child’s mental and physical development. A child’s daily life is inconceivadle without socializing. Through socialization the children starts to recogniz theyr personality and discovers theyr needs, learn and show a respect to one anoather, starts to understand the meaning of a language they speak . Children start to be awear of the consequences of theyr actions and finally sees them selfs as a part of the community like Rean, Skuskovina, Schulz von Thunss F. and other aouthors menthion in theyre research. In the practical part of the tesis the author of the work conducted a study of preschool children and a options of preventing aggressive behavior in kindergarden: where developed aggressive expression criteria, wich where used before and after observation. To analise the children where selected methodes wich could reduses aggressive behavior. The aouthor of the work to prevent aggressive behavior used: learning matherials, change of environment and a teacher support. The methods are based on social games, situation modeling, which are created to see positive and negative consequences of the action wich was made. Changing the environment causes a change in the emotional state, which reduces the need to act aggressively. The use of these sets has a positive effect on strengthening the child's self-control and avoiding aggressive behavior. The tesis contains 61 pages, 2 pictures, 5 charts, 5 appendices. 32 sources of literature and information were used, 24 are in Latvian and 8 in foreign language
Pox, Prose, and Prostitution: Masculine Anxiety, the Myth of the Male Author, and the Late-Victorian ‘Exchange Economy’ in George Gissing’s New Grub Street
No full textGeorge Gissing’s friend and fellow novelist, H. G Wells, would remember the ‘last decade of the nineteenth century’ as ‘an extraordinarily favourable time for new writers’(H. G. Wells, Experiment in Autobiography: Discoveries of a Very Ordinary Brain, Volume II (Since 1866) (London: Gollancz, 1934), p. 506.). His experience fits neatly with the myths of the successful Victorian male author that were in circulation throughout the century. For the vast majority of writers, however, the reality was quite different. As many scholars have recognized, George Gissing’s 1891 novel, New Grub Street, presents a realistic portrayal of the travails of the average writer trying to live by their pen at the turn of the century. Nonetheless, little work has examined these economic travails against the backdrop of nineteenth-century images of male authorship. Bringing together work on Victorian masculinities, research on cultural depictions of syphilis, and work on the nineteenth-century marketplace alongside current Gissing scholarship and primary sources, this article will argue that Gissing’s novel foregrounds the shared ‘exchange economy’ of prostitution and the literary market to explore specifically masculine anxieties around the male author at the fin de siècle (Monika Pietrzak-Franger, Syphilis in Victorian Literature and Culture: Medicine, Knowledge and the Spectacle of Victorian Invisibility (Cham: Palgrave Macmillan, 2017), p. 131.). In tracing the interconnections of pox, prose, and prostitution, this article re-negotiates the novel’s relationship with other images of Victorian authorship, as well as using work on cultural depictions of syphilis to position the text in a new field

No full textMāszinībasVeselības aprūpeNursing StudiesHealth CareBakalaura darba nosaukums ir “Skolotāju pieredze un izpratne pirmās palīdzības sniegšanā traumu gadījumos skolas vidē”. Darba autore Monika Blumbaha.
Bērni un pusaudži skolā pavada 25%-50% no sava dienas laika, kur daudzo grupu aktivitāšu dēļ ir vairāk pakļauti nejaušām traumām (Jaffe,2021). 2021.gadā reģistrēto traumu skaits kopā vecuma grupā no 5 līdz 19 gadiem bija 3358 gadījumi no kuriem 153 notikuši skolā vai izglītības zonā. Atskatoties uz 2010.g. reģistrēto traumu gadījumu skaits bija 3885, kur 444 norisinājās skolās (SPKC,2021).
Pētījumā izvirzītais mērķis: noskaidrot skolotāju pieredzi un izpratni pirmās palīdzības sniegšanā traumu gadījumos skolas vidē atkarībā no darba stāža.
Pētījuma metode: neeksperimentāls kvantitatīvs korelatīvs šķērsgriezuma pētījums. Kopumā pētījumā piedalījās 211 skolotājas no X vispārizglītojošu dienu skolām, kur skolotājas aizpildīja elektroniski izstrādātu aptauju.
Instrumentārijs: anketa, kura sastāv no trijām daļām – sociāldemogrāfisko un vispārēju datu daļas, informācija par pieredzi un zināšanām pirmās palīdzības sniegšanā un testa jautājumi daļas par pirmās palīdzības sniegšanu.
Rezultāti: Izvirzītā hipotēze par darba stāžu un izpratni neapstiprinājās, jo netika atrasta nozīmīga saistība , taču hipotēze par darba stāžu un pieredzi apstiprinājās, kur tika novērota vidēji spēcīga, statistiski nozīmīga, pozitīva saistība.

Summary
It is commonly thought that cases of life shorter than the life expectancy for Poles, mainly due to atherosclerosis and certain malignancies, are caused by, among other factors, consumption of large quantities of meat, especially pork. However, essential statistical data do not confirm this hypothesis, as an average Pole eats 41,1 kg pork per year, compared to 66.1 kg eaten by Spaniards, 64.2 kg by Danes, 59.9 kg by Austrians, 53.3 kg by Germans, while the average life expectancy for female and male Poles is 80.1 years and 71.5 years, respectively, and that for female and male Western Europeans is 82,2 years and 75 years, respectively. Meat is a necessary component of human diet because of its unique chemical composition, nutritional value and content of complete protein with favorable proportions of amino acids. Pork, whose nutritional value and pro-health properties have improved over the last 20 years, has a lower content of saturated fatty acids (SAFA) and a higher content of polyunsaturated fatty acids (PUFA) compared to beef. Compared to poultry meat, pork has a significantly better proportion of essential unsaturated fatty acids (EUFA), omega-3 (PUFA n-3) to omega-6 (PUFA n-6), whose excess is typical for the so-called “Western” diet. Cholesterol content is fairly similar in all parts of pork carcass, and it is much smaller than even 20 years ago. In comparison with other meat types, pork is characterized by 4–5 times higher content of vitamin B1. Pork is also characterized by a high content of readily available iron, a very often inadequately supplied mineral in humans. It is present in the quantity of 0.014 g/kg, which is higher than in poultry meat (0.009 g/kg) but lower than in beef (0.026 g/kg). In 2015, the International Agency for Research on Cancer (IARC) updated its classification of carcinogenic agents. Red meat and processed meat were classified by IARC to group 2.A: substances probably carcinogenic to humans. In its document, the international IARC workgroup revealed that consumption of meat brings health benefits, but consumption of processed and red meat should be limited as it can be associated with an increased risk of death due to atherosclerosic diseases and certain malignancies. Concurrently, it is noted that the results of many studies in this area are not clear. Production of genetically modified food is a very interesting, but also controversial area of studies of food, including pork.

Streszczenie
Powszechnie obowiązuje opinia, że przyczyną krótszej od przewidywanej długości życia Polaków i to głównie z powodu miażdżycy i niektórych nowotworów złośliwych jest między innymi spożywanie dużej ilości mięsa, a szczególnie wieprzowiny. Podstawowe dane statystyczne nie potwierdzają jednak tej opinii, ponieważ przeciętny Polak zjada rocznie 41,1 kg wieprzowiny a Hiszpan 66,1, Duńczyk 64,2, Austriak 59,9 i Niemiec 53,3 kg; natomiast średnia długość życia Polki wynosi 80,1 lat, Polaka 71,5 lat a w krajach Europy Zachodniej kobiety żyją średnio 82,2 lata a mężczyźni 75 lat. Mięso jest niezbędnym składnikiem diety człowieka ze względu na niepowtarzalny skład chemiczny, wartość odżywczą oraz zawartość pełnowartościowego białka o korzystnych proporcjach aminokwasów. Mięso wieprzowe, którego wartość odżywcza i prozdrowotna przez ostatnie 20 lat uległa znacznej poprawie ma niższą zawartość nasyconych kwasów tłuszczowych (SAFA) i wyższą zawartość wielonienasyconych kwasów tłuszczowych (PUFA) w porównaniu z mięsem wołowym. Natomiast w odniesieniu do mięsa drobiowego charakteryzuje się znacznie korzystniejszą proporcją niezbędnych nienasyconych kwasów tłuszczowych (NNKT) omega – 3 (PUFA n-3) do omega – 6 (PUFA n-6), którego nadmiar jest charakterystyczny dla tzw. diety „zachodniej”. Zawartość cholesterolu jest dość podobna we wszystkich elementach tuszy wieprzowej, a jego ilość jest znacznie mniejsza niż jeszcze 20 lat temu. W porównaniu z innym gatunkami mięs wieprzowina wyróżnia się 4 - 5 krotnie wyższą zawartością witaminy B1. Dla mięsa wieprzowego charakterystyczna jest także wysoka zawartość, dobrze przyswajalnego i bardzo często niedoborowego składnika mineralnego u człowieka a mianowicie żelaza. Jest ono obecne w ilości 0,014g/kg i jest wyższe w porównaniu z mięsem drobiowym 0,009 g/kg, ale też i niższe niż w wołowinie 0,026g/kg. Międzynarodowa Agencja Badań nad Rakiem (IARC) uaktualniła w 2015 roku klasyfikacje czynników i substancji rakotwórczych. IARC zaliczyła czerwone mięso oraz mięso przetworzone do grupy 2. A. – substancje prawdopodobnie rakotwórcze dla człowieka. Z dokumentu wypracowanego przez międzynarodową Grupę Roboczą IARC dowiadujemy się również, że spożywanie mięsa przynosi korzyści zdrowotne, jednak powinno ograniczyć się spożycie mięsa przetworzonego i czerwonego, którego spożywanie wiązać się może ze zwiększonym ryzykiem zgonu z powodu chorób na bazie miażdżycy i niektórych nowotworów złośliwych. Jednoczenie zaznacza, że wyniki wielu badań w tym zakresie nie są jednoznaczne. Bardzo ciekawym i jednocześnie kontrowersyjnym kierunkiem badań nad żywnością, w tym wieprzowiną jest produkcja żywności genetycznie zmodyfikowanej
