Saggers, Naomi J. "Selected topics in Limos Kalinga grammar." Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 1991. https://ro.ecu.edu.au/theses/1120.
Full textAbstract:
The Grammar is of the Limos Kalinga dialect, referred to by its speakers as Linimos. It . is one of ten Kalinga dialects belonging to the Central Cordilleran subgroup. An estimated 70,000 to 80,000 Kalingas live in the mountainous Kalinga subprovince of Kalinga Apayo in northern Luzon, Republic of the Philippines. Linimos itself is spoken by about 8,000 people living in about ten villages along the lower Saltan river in the municipality of Pinokpok . The Grammar comprises an Introduction, followed by a survey of the basic grammar of the language. This survey includes a chapter on word classes, including the distinction between nouns and verbs, a hazy area in Philippine linguistics. Then the noun phrase is described, with the focus on the complex deictic component of the determiner. The third chapter introduces the structure of the verb, and the focus morphology in particular. The relationship between the focus affixes and transitivity is of particular interest, as a transitivity continuum emerges along the lines of that proposed by Hopper and Thompson (1980) .The next major section of the Grammar describes both verbal and non-verbal . syntax, including subject and topic. Areas chosen for closer attention here are topicalization and identification sentences. The most detailed section of the thesis is the final one on Aspect. The perfectivity/imperfectivity distinction is described first, followed by the complex system of reduplication. There are three major types of reduplication, one of which frequently combines with consonant gemination, which produce aspectual distinctions on verbs. The results are significant for the comparative study of Philippine linguistics, as little has been done on the topic of aspect, particularly that indicated by reduplication. To have the basic outline of the grammar set out simply will be of benefit to those working in the area of translation and literacy, as well as for language learning and, again, for comparative linguistics.

Previous issue date: 2009-01-04<br>The direct use of natural gas makes the Solid Oxide Fuel Cell (SOFC) potentially more competitive with the current energy conversions technologies. The Intermediate Temperature SOFC (IT-SOFC) offer several advantages over the High
Temperature SOFC (HT-SOFC), which includes better thermal compatibility among components, fast start with lower energy consumption, manufacture and operation cost reduction. The CeO2 based materials are alternatives to the Yttria Stabilized
Zirconia (YSZ) to application in SOFC, as they have higher ionic conductivity and less ohmic losses comparing to YSZ, and they can operate at lower temperatures (500-800?C). Ceria has been doped with a variety of cations, although, the Gd3+ has the ionic radius closest to the ideal one to form solid solution. These electrolytes based in ceria require special electrodes with a higher performance and chemical and termomechanical compatibility. In this work compounds of gadolinia-doped ceria, Ce1-xGdxO2-δ (x = 0,1; 0,2 and 0,3), used as electrolytes, were synthesized by polymeric precursors method, Pechini, as well as the composite material NiO - Ce0,9Gd0,1O1,95, used as anode, also attained by oxide mixture method, mixturing the powders of the both phases calcinated already. The materials were characterized by X ray diffraction, dilatometry and scanning electronic microscopy. The refinement of the diffraction data indicated that all the Ce1-xGdxO2-δ powders were crystallized in a
unique cubic phase with fluorite structure, and the composite synthesized by Pechini method produced smaller crystallite size in comparison with the same material attained by oxide mixture method. All the produced powders had nanometric
characteristics. The composite produced by Pechini method has microstructural characteristics that can increase the triple phase boundaries (TPB) in the anode, improving the cell efficiency, as well as reducing the mass transport mechanism

Vilsono liga (VL) ir HFE-hemochromatozė – monogeninės, pagal Mendelio dėsnius paveldimos retos ligos. Šių ligų priežastis yra ATP7B arba HFE genų mutacijos, sukeliančios gyvybei pavojingas lėtines ligas. Šio darbo metu buvo tirti ligonių, sergančių metabolinėmis kepenų ligomis – VL ir HFE–hemochromatoze genų mutacijos, jų dažnis, ligų fenotipinės charakteristikos bei HFE geno dažniausių mutavusių alelių dažnis Lietuvos savanorių kraujo donorų populiacijoje. Buvo nustatyta, kad Rytų ir Centrinės Europos šalių populiacijoms būdinga c.3207C>A (p.His1069Gln) mutacija ATP7B gene taip pat dažniausia ir Lietuvoje. Patvirtinta, kad VL jautriausias metodas - molekulinis genetinis diagnostikos metodas. Kitiems klinikiniams laboratoriniams tyrimo metodams buvo būdingas mažesnis jautrumas. Ištyrus Lietuvos savanorius kraujo donorus nustatyta, kad HFE–hemochromatozės geno c.845G>A (p.Cys282Tyr) ir c.187C>G (p.His63Asp) mutacijų dažnis yra artimiausias Lenkijai ir kitoms Rytų ir Centrinės Europos šalims. HFE-hemochromatozės išsivystymo rizika yra 1,3 proc. Lietuvos savanoriams kraujo donorams, kurių genotipas c.[845G>A]; [845G>A] (0,1 proc. tiriamųjų) arba genotipas c.[845G>A];[187C>G], (1,2 proc. tiriamųjų). Tiriant HFE geno mutacijų paplitimą tarp skirtinguose Lietuvos etnokultūriniuose regionuose gyvenančių savanorių kraujo donorų nustatyta, kad c.845G>A mutacijos dažnis statistiškai patikimai buvo dažnesnis Žemaitijoje.<br>Wilson’s disease (WD) and HFE-hemochromatosis are monogenic rare diseases inherited following Mendel’s laws. These diseases are caused by ATP7B or HFE gene mutations, which cause life-threatening chronic diseases. This study analyzed gene mutations in patients with metabolic liver diseases – WD and HFE–hemochromatosis, the frequency of such mutations, the phenotypic characteristics of these diseases, and the frequency of the most common mutations in the alleles of the HFE gene in the population of Lithuanian volunteer blood donors. The study showed that the ATP7B gene mutation c.3207C>A (p.His1069Gln), which is characteristic of the populations of Central and Eastern Europe, was also most common in Lithuania. The study confirmed that molecular genetic diagnostics was the most sensitive technique in detecting WD. Other clinical laboratory diagnostic techniques demonstrated lower sensitivity. The examination of Lithuanian volunteer blood donors showed that the frequency of HFE–hemochromatosis mutations c.845G>A (p.Cys282Tyr) and c.187C>G (p.His63Asp) was closest to that in Poland and other Eastern and Central European countries. The risk of developing HFE-hemochromatosis among Lithuanian volunteer blood donors with genotype c.[845G>A]; [845G>A] (0.1% of the subjects) or c.[845G>A];[187C>G] (1.2% of the subjects) was 1.3%.

Robin, Frédéric. "Dynamique de la distribution, sélection de l’habitat et stratégie d’alimentation chez la barge à queue noire limosa limosa à l’échelle des sites d’hivernage français." Thesis, La Rochelle, 2011. http://www.theses.fr/2011LAROS324.
Full textAbstract:
La Barge à queue noire Limosa limosa est un oiseau limicole communément rencontré tout au long de l’année sur le territoire Français. Les individus présents sur la partie ouest de l’Europe sont représentés par deux sous-espèces : la sous-espèce L. l. limosa, dite barge à queue noire « continentale », est principalement observée pendant les phases de migration et en très faibles effectifs reproducteurs sur les marais ouest Atlantique; la sous-espèce L. l. islandica, dite « islandaise », est quant à elle, exclusivement présente en hivernage le long des côtes atlantiques et de la Manche. L’étude menée au cours de ces travaux de thèse porte principalement sur la barge « islandaise » en dehors de la période de reproduction sur les sites d’hivernage le long de la façade atlantique Française. Contrairement à L. l. limosa, la population de L. l. islandica connaît sur l’ensemble de son aire de répartition, une expansion aussi bien en termes d’effectif qu’en nombre de sites fréquentés. La synthèse des effectifs nationaux hivernants montre que la population hivernante en France suit cette même tendance, avec une progression de 1350 à 27000 individus au cours des vingt dernières années. Actuellement, la France accueille environ 30 % de la population sur un nombre de sites grandissant mais néanmoins restreint, principalement représentés par les Réserves Naturelles littorales abritant des vasières intertidales utilisés comme zone d’alimentation. À partir de données biométriques, génétiques ou encore des historiques de vie des oiseaux équipés de bagues couleurs, les périodes de présence des deux populations sur le territoire Français ont pu être mis à jour. De plus, au sein de la sous-espèce islandaise, plusieurs durées d’hivernage en France ont été avancées, pouvant varier de 2 à 8 mois selon les individus. La phénologie des effectifs étudiée sur chacun des sites suggère une utilisation très variée des sites ainsi que de nombreux échanges entre ces sites au cours d’un même hiver. Couramment utilisée dans la compréhension de la distribution des populations d’oiseaux, la disponibilité de la ressource trophique a également été étudiée au regard du régime alimentaire de la Barge queue noire à partir d’échantillonnages de macrofaune, de collecte de fèces mais aussi d’analyses d’isotopes stables. Au cours de l’hiver, à l’échelle des Pertuis Charentais, les barges montrent deux régimes distincts mais néanmoins monospécifiques. Elles s’alimentent de rhizomes de zostères (Zostera noltii) sur les herbiers des vasières de l’Ile de Ré et de bivalves (Macoma balthica) sur les vasières nues. Au cours de l’hiver, il est supposé que la déplétion de ces ressources conduit à une redistribution des effectifs de barges sur de nouvelles zones d’alimentation voire de nouveaux reposoirs. Les deux régimes alimentaires sont majoritairement retrouvés à l’échelle de la distribution nationale des barges. Néanmoins, leurs distributions au sein des sites français dépend des caractéristiques sédimentaires, des interactions intra et interspécifiques, de la disponibilité de reposoirs de marée haute et des dérangements tels que la chasse. Ce travail a permis d’établir de solides connaissances et aboutit à la collecte de données détaillées et complémentaires qui vont permettre de tester les modèles théoriques de distribution spatiale des organismes à l’échelle d’une région de leur aire de distribution<br>The Black-tailed godwit Limosa limosa is a shorebird species commonly observed in France throughout the year. Two sub-species are dissociated in West European. The so called “continental” Godwit L. l. limosa is observed in France during migration cycles and some pairs breed in marshes on the Atlantic coast; the so called “Icelandic” Godwit winters exclusively along coast of the Western Europe. This present work mainly investigates the wintering ecology of Icelandic–godwit in coastal mudflats of France. Contrarily to the continental sub-species, the whole Icelandic-godwit L. l. islandica population increased quantitatively as long as the number of sites used. In France, national counts pointed out that wintering population follows this trend and have increased from 1350 to 27000 individuals during the last twenty years. This population represents now around 30% of the whole islandica population but individuals stage in large flocks in a very limited number of sites, mainly included in Nature Reserves. From standard biometrics, molecular analyses and resighting data, phenologies of the both sub-species can then be specified for France. Furthermore, this study allowed to define how long the wintering period lasts in France for Icelandic-Godwits, between 2 and 8 months depending on individuals. Phenology at site scale suggested that godwits used several sites throughout the winter. As currently used for understanding the distribution of bird populations, trophic resource availability was studied in regard to the diet of the Black-tailed godwit from macrofauna sampling, droppings collection and stable isotope analyses. At the Pertuis Charentais scale, two feeding behaviors were clearly distinguished: seagrass grazing (Zostera notlii) or bivalve probing (Macoma balthica). Food depletion along the winter is expected to lead to the decrease of local populations, and to the selection of new feeding area or roost. Considering the distribution of the species at the national level, the diets were recorded depending on the mudflats’ characteristics. Even if food distribution is commonly used to understand at first the bird population distribution, our observations point out that, here at a local level, more parameters may influence the wintering distribution such as sediment characteristics, intra and inter-specific interactions, high tide roosts availability and human disturbances as the hunt. This work allowed to establish a solid knowledge and to collect many complementary data to test the distribution theories on the Black-tailed Godwit population wintering in France

Previous issue date: 2015-08-20<br>CAPES<br>The glyphosate, herbicide used in different countries, inhibits the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), blocking the synthesis of aromatic amino acids. With this, it still affects the activity of phenylalanine ammonia lyase (PAL) and the concentration of metabolites in plants. Its activity was first reported as a metal chelator. Therefore, to make use of this herbicide, may be formation of complexes with metals from soil, occurring change in the effectiveness of the product and loss of minerals. Thus, to avoid such problems,this study aimed to compare the effectiveness of three forms of glyphosate: purified, previously complexed with metals, and a commercial form (Roundup WG?). The effects of glyphosate complexes with copper, cobalt and nickel with different stoichiometries and different pH values on the in vitro activity of EPSPs were evaluated. Selected complex for the first experiment in vivo were Cu421 and Co821 (first number for pH and the latter two to stoichiometry glyphosate: metal). These complexes were used in the in vivo experiment I, as well as distilled water (control), purified Roundup and glyphosate on transgenic soybean and B. decumbens. In the following experiments (II and III), mineral oil was used in all treatments to reduce leaching of the compounds. The complex selected for continuation of this study was Cu421 due to its emphasis on the results obtained in the first experiment in vivo. When comparing the effect of the compounds in Falker Chlorophyll Index (ICF) of B. decumbens compared to control, there was fall of this index when using Roundup, Cu421 and purified glyphosate (the latter only in the second experiment). Later it was analyzed fresh mass accumulation and collected fresh material for determination of enzyme activities and N-NO3- levels. The complex Cu421 caused a more significant fresh mass reduction and still allowed the increase in the content of soluble nitrate in Brachiaria decumbens, probably due to the presence of nitrate in this complex. In the case of transgenic soybean there was no significant change in ICF. The use of Roundup and the complex did not change significantly the fresh mass accumul ation in this species. The application of the purified glyphosate, however, caused increase in mass accumulation and all treatments altered soybeans in nitrate content. In experiments with mineral oil in B. decumbens, the Cu421 complex inhibited significantly the EPSPs activity, as well as purified Roundup and glyphosate (the latter only in the experiment III). No inhibition occurred in transgenic soybean. All treatments in vivo stimulated PAL activity only on weed, which suggests that the increase in this activity is a consequence of the inhibition of EPSPs and other deleterious effects of compounds on susceptible plants. This study showed that especially Cu421 complex might be used effectively as a herbicide since it inhibits EPSPs, activates the PA,L reduces fresh mass accumulation and influences photosynthesis in the tested weed. Besides, the transgenic soybean showed little sensitive to this compound, which further increases the prospect of using the same as herbicide.<br>O glifosato, herbicida usado mundialmente, atua inibindo a enzima 5-enolpiruvil-chiquimato- 3-fosfato-sintase (EPSPs), bloqueando a s?ntese de amino?cidos arom?ticos. Com isso, ainda influencia a atividade de fenilalanina am?nia liase (PAL) e a concentra??o de metab?litos nas plantas. A sua primeira a??o reportada foi como agente quelante de metais. Portanto, ao fazer uso deste herbicida, pode haver forma??o de complexos com metais do solo, ocorrendo altera??o da efic?cia do produto e defici?ncia mineral. Assim, de modo a evitar tais problemas, este trabalho teve como objetivo, comparar a efici?ncia de tr?s formas de glifosato: purificado, previamente complexado com metais, e uma das suas formas comerciais (Roundup WG?). Os efeitos de complexos de glifosato com cobre, cobalto e n?quel, sintetizados sob diferentes estequiometrias e valores de pH, foram avaliados sobre a atividade in vitro de EPSPs. Os complexos selecionados para o primeiro experimento in vivo foram: Cu421 e Co821 (primeiro n?mero referente ao pH e os dois ?ltimos ? estequiometria glifosato:metal). Estes complexos foram usados no experimento in vivo I, assim como ?gua destilada (controle), Roundup e glifosato purificado, sobre soja transg?nica e Brachiaria decumbens. Nos experimentos seguintes utilizou-se ?leo mineral em todos os tratamentos para reduzir a lixivia??o dos compostos. O complexo selecionado para continua??o deste estudo foi o Cu421 devido a seu destaque nos resultados obtidos no primeiro experimento in vivo. Ao comparar o efeito dos compostos no ?ndice de Clorofila Falker (ICF) de B. decumbens em rela??o ao controle, observou-se queda deste ?ndice ao usar Roundup, Cu421 e glifosato purificado (este ?ltimo, somente no segundo experimento). Posteriormente foi analisado ac?mulo de massa fresca e coletado material fresco para determina??o das atividades enzim?ticas e dos teores N-NO3-. O complexo Cu421 foi o que provocou maior redu??o da massa fresca e ainda possibilitou o aumento no teor sol?vel de nitrato em B. decumbens, provavelmente devido ? presen?a de nitrato neste complexo. No caso da soja transg?nica n?o houve altera??o significativa de ICF. O uso de Roundup e dos complexos n?o alterou de forma significativa o ac?mulo de massa fresca nesta esp?cie. A aplica??o do glifosato purificado, entretanto, causou incremento no ac?mulo de massa e todos os tratamentos alteraram o teor de nitrato em soja. Nos experimentos com ?leo mineral em B. decumbens, o complexo Cu421 inibiu de forma significativa a atividade de EPSPs, assim como Roundup e glifosato purificado (este ?ltimo, somente no experimento III). Em soja transg?nica n?o houve inibi??o. Todos os tratamentos in vivo estimularam a atividade de PAL somente na gram?nea, permitindo sugerir que o aumento nesta atividade seja consequ?ncia da inibi??o de EPSPs e de outros efeitos delet?rios dos compostos sobre plantas suscept?veis. O presente estudo mostrou que principalmente o complexo Cu421 pode vir a ser utilizado de forma eficaz como herbicida, uma vez que inibe a EPSPs, ativa a PAL, reduz ac?mulo de massa fresca e influencia a fotoss?ntese na planta daninha testada. E, em contrapartida, a soja transg?nica mostrou-se pouco sens?vel a este composto, o que aumenta ainda mais a perspectiva do uso do mesmo como herbicida.

Todėl pastaraisiais metais daug dėmesio skiriama hemodializuojamų pacientų priežiūrai gerinti: hemodializės kokybei, pacientų mokymui, anemijos ir hipertenzijos kontrolei, mitybai ir panašiai. Todėl ši tema yra ir bus aktuali, kadangi pacientų mokymas yra svarbus visose sveikatos priežiūros įstaigose, o slaugytojo pareiga- mokyti sveikus ir sergančius pacientus. Slaugytojai sveikus pacientus supažindina su ligų profilaktika, o sergančius apmoko teisingai vartoti vaistus, išaiškina gydymo režimą, supažindina su dietos ypatumais, moko prisitaikyti prie naujų gyvenimo sąlygų, sugebėti kontroliuoti ir valdyti ligą. DARBO TEMA- hemodializuojamų pacientų mokymo svarba ligos valdyme. TIKSKLAS- nustatyti mokymo svarbą, hemodializuojamų pacientų ligos valdyme. UŽDAVINIAI: 1. Išanalizuoti slaugytojo vaidmenį mokant hemodializuojamus pacientus. 2. Įvertinti slaugytojo žinias apie ligą ( LIFN ). 3. Įvertinti hemodializuojamų pacientų žinias apie ligą (LIFN ). 4. Nustatyti mokymo apimtį ir kryptis. DARBO METODAI: 1. Teorinė apžvalga; 2. Anketinė apklausa.

Veterinarinė odontologija – tai nauja greitai besivystanti veterinarinės medicinos sritis. Daugelyje šalių veterinarinė odontologija jau egzistuoja kaip atskira disciplina, tirianti dantų ir burnos ertmės ligas, profilaktiką bei gydymą.
Remiantis statistiniais duomenimis, dantų, žandikaulio ir burnos ertmės ligos gyvūnų tarpe - labai paplitusios visame pasaulyje. Daugiau nei 95 proc. kačių ir šunų per visą jų gyvenimą pasireiškia dantų ir burnos ertmės patologijos. Kadangi kačių dantų ligų gydymas yra gana sudėtingas ir skausmingas gyvūnui procesas, geriau tinka taikyti profilaktikos priemones, nei gydymą. Todėl nuo mažens gyvūną reikia pratinti prie burnos ertmės higienos.
Lietuvoje dar labai mažai dėmesio skiriama šiai problemai. Deja, tik 8 proc. gyvūnų savininkų laiku pastebi dantų ligų požymius. Šeimininkai neskiria reikalingo dėmesio savo augintinio burnos ertmės priežiūrai, nesusimąstydami, kad dantų ligos gali būti bendros gyvūno savijautos pablogėjimo ir daugelio ligų priežastimi.
Darbo tikslas – nustatyti kačių sergamumą dantų ligomis, bei apžvelgti jų gydymą ir profilaktikos priemonių taikymą.
Darbo uždaviniai:
1. išanalizuoti ir apžvelgti literatūros šaltinius, susijusius su šia tema;
2. išnagrinėti dantų ligų diagnozavimo ir gydymo metodus;
3. išsiaiškinti ar kačių lytis turi įtakos dantų ligų pasireiškimui;

To examine and review literature sources and information concerning the work objectives. 2. To review dental disease diagnostic and treatment methods. 3. To detemine whether cat gender has an effect on dental diseases. 4. To determine which dental diseases are the most popular in cats. 5. To determine what kind of dental diseases are the most popular in age groups. 6. To determine which breed of cats most likely have dental diseases. 7. To analyze prevention measures of dental disease. The research results and conclusions are: Cat sex does not have an effect on dental diseases. Dental diseases are most likely to develop in mixed breed cats. The most popular dental disease in cats is calculus. Mostly dental diseases affect cats which are older than 10 years. Periodontitis usually affects cats at age of 7 to 9 and those older than 10 years. Dental diseases mostly occur in the Siamese – oriental group of cat, and less longhaired cat group. The most common prevention measure is the specific cat food for teeth. Most cat owners do not clean their cat teeth in veterinary clinic. In conclusion, the cat owners do not have enough knowledge about dental diseases, its treatment and prevention factors.

Dabartiniai gydytojai bronchinei astmai gydyti turi tikrai veiksmingų bei patikrintų medikamentų, visgi dažnai išlieka nesėkmingo gydymo ar nepakankamai geros šios ligos kontrolės problema. Šiuolaikiniai tyrimai rodo, jog vien tik biologiniai, medicininiai ar ekonominiai faktoriai nepaaiškina nesugebėjimo pasiekti ligos kontrolės priežasčių, todėl ypatingą dėmesį, susijusį su nesugebėjimu pasiekti astmos kontrolės, skiria psichosocialiniams faktoriams. Taigi šiuo tyrimu siekėme analizuoti psichologinių veiksnių sąsajas su astmos kontrole: bandėme įvertinti ir aprašyti kaip astma sergantys paaugliai bei jų mamos suvokia ligą ir kaip ligos suvokimas (tiek pačių sergančių vaikų, tiek jų mamų) yra susijęs su paauglių jaučiamu nerimo lygiu; taip pat bandėme analizuoti kaip sergančių paauglių ir jų mamų ligos suvokimas, paauglių nerimo lygis yra susiję su astmos kontrole. Tyrime naudojome Eiser (1995) sukurtą paauglio ligos suvokimo skalę, March (1997) multidimensinę nerimo skalę vaikams, standartizuotą astmos kontrolės klausimyną bei Bonner, Hardy, Guill, McLaughlin, Schweitzer, Cartier (2006) tėvų suvokto vaiko ligos patyrimo skalę. Tyrime dalyvavo 60 astma sergančių paauglių ir jų mamų. Paauglių amžius svyruoja nuo 11 iki 18 metų. Mūsų tyrimo rezultatai rodo, kad kuo negatyviau paauglys suvokia savo ligą, tuo jo nerimo lygis yra aukštesnis.

However, the problem of unsuccessful treatment and insufficient control of this illness still remains. Recent research shows that only biological, medical and economic factors do not explain the inability to control the cause of the illness, thus special attention is paid to psychosocial factors. The link between psychological aspects and asthma control was analyzed in this research. An attempt was made to evaluate and describe the way teenagers suffering from this illness and their mothers perceive the illness and the way this perception (both of sick children and their mothers) is connected with the level of anxiety felt by teenagers. The illness perception both of sick teenagers and their mothers and the connection between the level of anxiety and asthma control also were studied in the research. Perceived illness experience scale created by Eiser (1995), multidimensional anxiety scale for children by March (1997), standardized asthma control questionnaire and parent experience of childhood illness scale by Bonner, Guill, McLaughlin, Schweitzer, Cartier (2006) were used in the research. 60 teenagers ill with asthma and their mothers were involved in the research. The age of teenagers ranged from 11 to 18. The results of our research proved the connection between two factors: the more negative perception of illness of teenager is, the higher level of anxiety becomes. The research also... [to full text]

Retosios ligos (RL) – tai ypač mažai paplitusios ligos (gyvybei pavojų keliančios arba lėtai sekinančios ligos), kuriomis Europos Sąjungoje (ES) serga ne daugiau kaip 5 iš 10 000 asmenų. Pirmą kartą terminą „retosios ligos“ 1978 metais pavartojo Neilas A. Holtzmanas. Kiekviena RL ES serga apie 246 000 žmonių. Iš viso RL, kurių žinoma 5 000 – 8 000, kokiu nors gyvenimo etapu suserga apie 6% ES gyventojų ir tai yra 29 – 36 mln. ligonių. Lietuvoje sergančių RL galėtų būti apie 200 000 žmonių. Dauguma RL yra genetinės ligos (jos sudaro 80%), o likusios – kitų kategorijų retos vėžio formos, autoimuninės ligos, įgimtos raidos anomalijos, toksinės ir infekcinės ligos. Habilitacijos procedūrai teikiamų mokslo darbų apžvalgoje nagrinėtos 22 mokslinės publikacijos. Istoriniai šaltiniai apie RL gali būti anatominių preparatų muziejai, antikvarinės knygos medicinine tematika, tautosaka. Apžvalgoje nagrinėta Vilniaus universiteto Medicinos fakulteto anatominių preparatų kolekcija, kurioje nustatytas unikalus žmogaus anotocefalijos atvejis ir 11 kitų nozologinių RL (įgimtų anomalijų) vienetų. Pagrindinės priemonės žinioms apie RL turtinti ir klinikiniams moksliniams tyrimams plėtoti yra registrai ir duomenų bazės. Tai vienintelis būdas kaupti duomenis, kad būtų galima gauti pakankamo dydžio imtis epidemiologiniams ir (arba) klinikiniams tyrimams.

Kriaučeliūno smulkiųjų gyvūnų klinikoje buvo renkami duomenys apie šunų sergamumą bakterinėmis odos ligomis. 301 šuniui buvo diagnozuota odos ligos (201 iš sirgusiųjų sirgo bakterinėmis ligomis, 95 iš jų patelės, 106 – patinai). Klinikinė diagnozė patvirtinta remiantis atliktais mikroskopiniu, mikologiniu ir bakteriologiniu tyrimais. Patinai odos ligomis sirgo dažniau nei patelės (55,48 proc. palyginti su 44,52 proc.) ir dažniausiai sirgo šunys, kurių amžius buvo nuo vienerių iki penkerių metų (43,52 proc.), rečiausiai – vyresni nei penkerių metų šunys (26,24 proc., p<0,001). Dažniausiai odos ligomis šunys serga pavasarį (33,90 proc., p<0,001), rečiausiai rudenį (16,60 proc., p<0,001).

Thesis: Ph. D., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2016.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 175-181).<br>Humans possess the remarkable ability to control their four natural limbs in a voluntary, accurate and independent manner. The simultaneous use of two or more limbs allows humans to learn and robustly perform a wide range of complex tasks. Since the use of multiple limbs enables humans to master advanced motor skills, it would be interesting to study whether having additional limbs would enable users to expand their skill set beyond its natural limits. Inspired by this vision, we propose a new form of human augmentation: a wearable robot that augments its user by providing him with an additional set of robotic limbs. We named this new device Supernumerary Robotic Limbs (SRL). However, humans have never had the possibility to control additional, powered limbs besides their natural arms and legs. The main theme of this thesis, besides realizing a prototype of the robot and proving its usefulness in realworld tasks, is demonstrating that humans can voluntarily control additional limbs as if they were a part of their own body. We realized a lightweight (3.5 kg), comfortable prototype of the SRL that can be easily worn by an unassisted user. Two robotic limbs can assist the user in both manufacturing and locomotion tasks. We created control strategies that take advantage of the independence of the robotic limbs, enabling them to provide optimal assistance in specific tasks such as weight support, body stabilization, using powered tools, sitting/standing and dynamic walking. Finally, we developed an EMG-based control interface that enables users to voluntarily control the motion of the robotic limbs, without interfering with the posture of the rest of the body. The new augmentation technology presented in this thesis opens up new possibilities in the field of wearable robotics. The voluntary control of additional robotic limbs falls within the range of motor skills that humans can learn, and enables the acquisition of a new set of complex skills that would not be achievable using only the natural body..<br>by Federico Parietti.<br>Ph.

Thesis: S.B., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2014.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 46-47).<br>Overhead tasks such as those frequently found in aircraft manufacturing pose health risks to the workers due to the strain imposed on the shoulders. To reduce the risk of injury, a set of supernumerary robotic limbs (SRL) were designed to perform these overhead tasks. The SRL is designed with limits in the hardware and software to protect the human and prevent collisions between robot and operator. The arms are designed to have a workspace above and in front of the head of the user free from singular configurations so the robot is free to operate where the tasks will be performed. To further protect the human, the mount that attaches the SRL to the shoulders was redesigned to be lighter and to better distribute the load. In this manner, the shoulders will become less fatigued from the static load of carrying the SRL To complete the task of positioning cables and routing them through the ceiling of an airplane, a winch end effector was designed to latch onto the fuselage arches and pull the cable through these arches. In order to control the SRL, the concept of principal components analysis was used to reduce the input space. This concept was specifically used to map the motion of the operator's hands onto the appropriate speed for the winch motor to operate. In this manner, the winch would pull the cable at the same rate that the human fed the cable. The human would then be able to control the speed of the winch simply by executing the task at whatever pace they so desired.<br>by Jay McKenna.<br>S.B.

Full textAbstract:
La introducción del NiTi ha supuesto una revolución en el tratamiento de conductos, reduciendo la fatiga del operador y el tiempo necesario para acabar la preparación y minimizando el número de errores asociados a la instrumentación. Desde la introducción de estos instrumentos se han presentado un gran número de sistemas rotatorios de NiTi, que difieren básicamente entre ellos en el diseño de sus hojas cortantes y en la conicidad de sus limas. Las últimas propuestas de los fabricantes son las limas de Niquel-Titanio de pequeño calibre y conicidad para la realización del Glide Path rotatorio, sustituyendo a la clásica preparación inicial manual en acero inoxidable.
Acorde a la literatura, el punto ideal donde debe acabar nuestra instrumentación y obturación es la unión cementodentinaria. Esta referencia anatómica representa la parte del conducto radicular de menor diámetro y la transición entre el espacio pulpar y el ligamento periodontal. Existen estudios microscópicos que estiman que la distancia entre este punto más estrecho del conducto ó constricción apical y la superficie externa de la raíz varía entre 0,5 y 1,0 milímetros. Una longitud de trabajo medida más allá de esta constricción puede resultar en una sobre-instrumentación del ápice con el consecuente dolor postoperatorio, deformación de la porción final del conducto y/o fracaso del tratamiento a largo plazo.
Aunque los localizadores electrónicos de ápices (LEA) son una gran ayuda para localizar el final del conducto no pueden sustituir la necesidad de utilizar radiografías. Existen estudios que indican que es frecuente que los LEA obtengan falsas medidas, abogando por la necesidad de continuar utilizando radiografías.
Por lo tanto, existen tres situaciones en endodoncia donde la lima puede pasar a través del foramen mayor: por un error a causa de la inexperiencia del operador, por una medida errónea de longitud de trabajo o de manera intencional mediante la técnica del uso de la lima pasaje.
Durante la conformación del conducto se producen detritus y restos de dentina que pueden llegar a bloquear la porción apical del conducto, favoreciendo la formación de escalones, transporte de la posición original del conducto y perforaciones. Una manera de prevenir el acúmulo de estos detritus es mediante el concepto de permeabilidad, que según Buchanan consiste en hacer pasar de manera pasiva una lima manual de pequeño calibre a través de la constricción apical sin ensancharla.
En esta tesis doctoral se observaron las consecuencias de la utilización de diferentes instrumentos a nivel del foramen mayor y la deformación producida por los mismos.
Se realizaron dos estudios, en nuestro primer estudio se observaron los efectos sobre el foramen mayor de la sobre-instrumentación con limas rotatorias de NiTi de preparación apical, basándonos en la hipótesis de las medidas erróneas de los LEA .

Full textAbstract:
La tesi si propone di analizzare la nascita e lo sviluppo di confini e frontiere che, in molti casi, hanno portato all’innalzamento di veri e propri muri, in un contesto, quale quello attuale, di globalizzazione. Di conseguenza, il risultato è una visione politica, economica, culturale e sociale ossimorica. L’obiettivo di questa tesi, dunque, è quello di fornire un’analisi geopolitica sulla situazione di confini e frontiere nel mondo tramite l’approfondimento dei casi più famosi e ignoti, al fine di comprendere i meccanismi economico-politici che spingono un governo a promuovere determinate politiche estere.
L’analisi parte dall’etimologia storico-linguistica del termine “confine”, dalla sua origine greco-latina fino ad arrivare al suo uso moderno nelle varie lingue. Successivamente, si propone un focus sulla definizione di frontiera dal punto di vista del diritto internazionale, partendo dal trattato di Westfalia fino ad arrivare alla Carta delle Nazioni Unite. Da ciò si capisce come nasce - politicamente e successivamente geograficamente - una frontiera e qual è l’iter per il consolidamento e il riconoscimento della stessa. Si è ritenuto utile un approfondimento su alcuni casi di frontiere “ereditarie”, ossia quelle di origine storico-culturale che oggi causano instabilità, tensioni, guerre e violazioni dei diritti umani.
I primi tre casi descrivono situazioni territoriali extraeuropee. Il primo caso riguarda gli accordi Sykes-Picot che hanno tracciato una linea di divisione alquanto arbitraria nei territori del Medio Oriente. Il secondo caso è spesso protagonista dei telegiornali nazionali: stiamo parlando del muro che divide Messico e Stati Uniti. Il terzo caso esamina la situazione della Triplice Frontiera, situata tra Paraguay, Brasile e Argentina, che causa tensioni politiche ed economiche tra i tre paesi e gli Stati Uniti.
I successivi casi riguardano, invece, le frontiere europee. Dalla rotta balcanica si passa al caso dell’isolotto inabitato e sperduto di Rockall, conteso da ben quattro paesi. Vengono presi in esame anche le vicende relative allo Stretto di Gibilterra, che causa tensioni continue tra Regno Unito e Spagna, all’isolotto di Perejil, rivendicato sia dalla Spagna che dal Marocco, e alla cosiddetta “guerra brexit” tra Regno Unito e Francia nelle acque del canale della Manica per i diritti di pesca, divenuti ambigui dopo l’uscita del primo dall’Unione europea.
Successivamente, viene introdotto il concetto di frontiere “invisibili”, ossia quelle che non hanno realtà fisica, ma non per questo sono meno incisive delle altre. Possiamo includere in questo tipo di frontiere quelle aeree, quelle internazionali marittime, quelle immaginarie o arbitrarie. Per comprendere a pieno la differenza tra queste frontiere, vengono approfonditi la linea Kármán, il 10° parallelo, il Mar Cinese, il Caspio, l’Artico e il Monte Bianco.
Tra le frontiere “visibili” ci sono i muri, costruiti per difendere i confini del proprio paese. I muri moderni hanno diverse funzioni: difesa contro il terrorismo, regolazione dei flussi migratori e contenimento dei traffici illegali di ogni genere. Sono sparsi in tutto il mondo, dall’America all’Asia, inclusa anche l’Europa. Vengono approfondite le questioni riguardanti la città portuale del nord della Francia, Calais, dove è stato eretto il “Great Wall”, la costruzione del Muro Marocchino, la Linea di demarcazione militare tra la Corea del Nord e la Corea del Sud, la “green line” a Cipro e la barriera di separazione israeliana.
In questa analisi, sono inclusi anche “casi” frontalieri davvero particolari. Ci riferiamo alle zone extraterritoriali, alle terrae nullius e alle enclave.

Full textAbstract:
L'étude du comportement des sols fins sollicités en traction a suscité l'intérêt des chercheurs et des ingénieurs pour de nombreuses applications depuis plus d'un demi siècle. Cependant, elle est restée sans issues claires, notamment pour l'identification du comportement des sols en traction pour des états de saturations différentes. La complexité est essentiellement d'origine expérimentale. Cette question est de nouveau posée. Des contributions récentes, assez prometteuses, permettent d'apporter un éclairage nouveau sur ces aspects. Ce travail de recherches s'intègre donc dans cette voie, où l'on cherche à apporter des éléments de réponse quant à la faisabilité et à l'interprétation d'un certain nombre d'essais de laboratoire de traction directe ou indirecte.En se focalisant sur la détermination de la résistance à la traction d'un sol fin à un état de saturation donné, on a réalisé des essais au laboratoire sur un limon (assimilé à un matériau fin), se trouvant sur un site choisi initialement pour héberger un centre de stockage des déchets solides ménagers. La problématique relative à ce type d'application, est liée au fait qu'un tel sol (le limon) est utilisé majoritairement pour la construction de la couche de couverture, et qu'il risque donc d'être fortement sollicité en traction par flexion quand les déchets subissent des tassements. Dans ce but, l'étude expérimentale a été orientée vers des essais de traction indirecte à savoir l'essai de fendage et l'essai de flexion.La complexité d'une telle étude réside, d'une part, dans l'interprétation qu'on peut en faire et, d'autre part, dans le couplage des effets de plusieurs paramètres (liés à la préparation de l'échantillon, les conditions initiales de saturation et de densité des échantillons, les dimensions des éprouvettes, les conditions aux limites associées à ces essais).En faisant une étude paramétrique et une analyse fine de la réponse de ce matériau, via une méthodologie numérique qui nous semble bien appropriée (méthode des éléments distincts, DEM), nous avons apporté des éléments de réponse aux interprétations des essais de traction indirecte. L'approche DEM est appliquée selon une démarche de calibrage des paramètres sur la base des essais de cisaillement au triaxial. On montre que l'essai de fendage ne pourrait pas fournir la résistance à la traction uniaxiale (valeur de référence obtenue numériquement par la DEM par un essai de traction directe) même si l'initiation de la fissure apparaissait au centre. Une telle condition n'est satisfaite que pour un aplatissement de l'éprouvette cylindrique d'un angle au centre de la section par rapport à la génératrice variant de 10° à 12°.D'un autre côté, l'essai de flexion interprété selon le modèle différentiel semble donner une bonne estimation de la résistance à la traction uniaxiale.Dans ce travail de recherches, bien que la démarche numérique par éléments distincts semble dépendre des essais de laboratoire nécessaires au calage, sa potentialité demeure très importante puisque, non seulement elle offre l'opportunité de simuler des essais complexes de laboratoire, mais aussi elle permet d'avoir des outils d'interprétation fiables.

Pagrindiniai darbo uždaviniai: a) įvertinti meteorologinių rodiklių bei klimatinių indeksų sąsajas su susirgimų peršalimo ligomis skaičiumi Lietuvoje. b) nustatyti atmosferos cirkuliacijos pobūdį, pernašos srautų kryptį bei barinių darinių padėtį 1995-2004 metų epideminių laikotarpių Lietuvoje metu. Darbe analizuojamas meteorologinių rodiklių (minimalios, maksimalios, vidutinės paros oro temperatūros, santykinio oro drėgnumo bei vėjo greičio) poveikis peršalimo ligoms (gripui ir ūmioms viršutinių kvėpavimo takų infekcijoms) Vilniuje, Kaune Klaipėdoje, Šiauliuose bei Panevėžyje. Taip pat įvertinta klimatinių indeksų (komfortabilumo, diskomforto bei vėjo žvarbumo) sąsaja su susirgimų peršalimo ligomis skaičiumi penkiuose Lietuvos miestuose. Peršalimo ligų skaičių atspindi vadinamasis epideminis gripo rodiklis, kuris skaičiuojamas dešimčiai tūkstančių gyventojų.

Auglių nekrozės faktorius (TNF - tumor necrosis factor) yra citokinas, kuris dalyvauja sukeliant uždegimą. Išskiriamas daugiausia makrofagų, bet taip pat ir limfocitų, endotelio ląstelių, adipozinio audinio ląstelių, širdies miocitų, nervinio audinio ląstelių. Padidėjusi TNF koncentracija sukelia pagrindinius uždegimo požymius: karščiavimą, tinimą, paraudimą ir skausmą. TNF skatinamas uždegiminis atsakas gali sukelti daug sveikatos problemų, susijusių su autoimuniniais sutrikimais – reumatoidinį artritą, ankilozinį spondilitą, Crohn‘o ligą, psoriazę, bronchinę astmą. Tyrimai parodė, jog, užblokavus TNF, pacientų būklė pagerėja. Šias ligas galima gydyti panaudojant TNF inhibitorius, kurių vaidmenį puikiai galėtų atlikti TNF surišantys antikūnai. Monokloniniai antikūnai tampa vis populiaresniais įrankiais analitiniuose ir diagnostiniuose metoduose, taip pat ir vis reikšmingesne terapine priemone. Tačiau antikūnų praktinį pritaikymą apsunkina jų imunogeniškumas, sudėtingas ir brangus jų gavimas, nepageidaujamas biologinis aktyvumas, ribotas afiniškumas bei sugebėjimas įsiskverbti į audinius (Zola et al., 1995). Siekiant šias problemas išspręsti yra kuriami rekombinantiniai antikūnai. Norint išvengti imunogeniškumo naudojami chimeriniai (IgG žmogaus, o Fab fragmentas – iš pelių), humanizuoti (iš pelės yra jau tik CDR rajonas) ak. Antikūnų fragmentai Fab, Fv gali taip pat jungtis prie antigeno kaip jų „tėvinės“ molekulės, net jei afiniškumas ir sumažėja. Tačiau, skirtingai nuo...

Tumor necrosis factor promotes the inflammatory response, which, in turn, causes many of the clinical problems associated with autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, Crohn's disease, psoriasis and refractory asthma. These disorders could be treated using a TNF inhibitors. Antibodies against TNF proved to be the most perspective instrument for therapy of increased level of TNF.. Recombinant single chain antibodies (scFv) might be excellent alternative to expensive and complicated monoclonal antibodies. The scFv are recombinant antibody fragments consisting of only two domains: the variable light chain (VL) and variable heavy chain (VH) domains, covalently connected to one another by polypeptide linker. The benefits of scFv over traditional monoclonal antibodies shoul be the small penetrable size and rapid, inexpensive production. In addition, the lack of Fc domains makes them less immunogenic and less capable for binding to Fc receptors distributed on the normal cells. In this work we tried to construct and express scFv antibodies against TNF. Firstly, for this purpose we purified total RNA from hybridoma cells, producing monoclonal anti-TNF antibodies. Then we synthesised cDNA and isolated PCR fragments of variable heavy and light chain domains of monoclonal antibodies against TNF.

Previous issue date: 2016<br>This work had as objective: to analyze the content addressed in the textbooks of Chemistry of High School on the subject of polymers; Prepare a guide of experimental demonstrations on the subject that can be used by high school teachers; And to carry out a pedagogical intervention in a 3rd grade class at a public school. For the analysis of textbooks, volume 3 was chosen, which was proposed by the National Textbook Plan (PNLD / 2015). This was of a quantitative nature and had as reference the proposed model of Bardin. In the same it was evaluated how the books approach the specific content on the subject polymers and as well as the approach through generating themes. After analyzing the textbooks, a guide of experimental
demonstrations was prepared, with reference to the contextualization of the subject under study, which can be used by high school teachers when approaching the topic of polymers. Following the elaboration of the material, a pedagogical intervention was carried out in a class of 3rd year of High School, of a public school located in the municipality of Ipu-CE. This intervention was based on the material formulated by the researcher. At the end, a Likert scale questionnaire was applied in order to verify the degree of satisfaction of the students about the intervention performed in the classroom. In general, it was observed that all the textbooks analyzed deal with the topic of polymers in their collections, however they have deficiencies in approaching it in a contextualized way, as in most of the analyzed collections, it was noticed that there is a
small number of demonstrations The same. Also, through the application of the pedagogical intervention, it was observed that by working on the theme in a contextualized way, combined with the use of experimentation, teaching-learning becomes more effective, so this combination of methodological practices becomes a potentiator of teacher making.<br>Este trabalho teve como objetivo: analisar o conteúdo abordado nos livros didáticos de Química do Ensino Médio sobre o tema polímeros; elaborar um guia de demonstrações experimentais sobre o tema que possa ser utilizado por professores do Ensino Médio; e realizar uma intervenção pedagógica em uma turma de 3º ano do Ensino Médio de uma escola pública. Para a análise dos livros didáticos foi escolhido o volume 3, este que foi proposto pelo Plano Nacional do Livro Didático (PNLD/2015). Essa foi de natureza quantitativa e teve como referência o modelo proposto do Bardin. Na mesma avaliou-se como os livros abordam o conteúdo específico sobre o tema polímeros e bem como a abordagem através de temas geradores. Após a análise dos livros didáticos foi elaborado um guia de demonstrações experimentais, com referência a contextualização do tema em estudo, o qual pode ser utilizado por professores do Ensino Médio ao abordarem o tema polímeros. Sequencialmente à elaboração do material, realizou-se uma intervenção pedagógica em uma turma de 3º ano do Ensino Médio, de uma escola pública localizada no município de Ipu-CE. Essa intervenção teve como base o material formulado pelo pesquisador. Ao final, foi aplicado um questionário de escala de Likert, a fim de verificar o grau de satisfação dos alunos sobre a intervenção realizada em sala. Em geral, observou-se que todos os livros didáticos analisados abordam o tema
polímeros em suas coleções, entretanto apresentam deficiências em abordá-lo de forma contextualizada, como também, na maioria das coleções analisadas, percebeu-se que há um número diminuto de demonstrações experimentais sobre o mesmo. Ainda, mediante a aplicação da intervenção pedagógica observou-se que ao trabalhar o tema de forma contextualizada aliado ao recurso da experimentação permite que o ensino-aprendizagem seja mais efetivo, logo, essa junção de práticas metodológicas torna-se uma potencializadora do fazer docente.

Previous issue date: 2014<br>The state of Ceará is gaining attention as an emerging state in fruit production in the country. Lemons 'Sicilians', traditionally grown in the south, has been planted in this region, however, there still exist a lot of information about the quality of fruits grown locally. Lemon ‘Siciliano’ hybrid 'Eureka' is a non-climacteric fruit, should be harvested, bought and traded with their quality attributes related to the ideal flavor for consumption. The study aimed to determine the proper stage of maturity lemon ‘Siciliano’ at harvest through physical and physicochemical periodic measurements during development and fruit growth. Two experiments were conducted, following two separate flowerings. The first four samples were taken every 15 days and from the 49th day, the crops became every 7 days until the 91 th day being thus held a total of 11 samples at 0, 14, 28, 42 , 49, 56, 63, 70, 77, 84 and 91 days. . At each time, a total of 20 fruits were divided into 4 groups were collected and, thus, five replicates. The first experiment was conducted from October 2012 to January 2013 and the second in the months from July to October 2013. Fruits were assessed for physical and physicochemical characteristics: fresh weight, longitudinal and transverse diameters (DL / DT), format index, firmness of the peel, juice yield, thickness of the peel, color (h*, C* and L*) and chlorophyll content of the peel, pH, titratable acidity (TA), soluble solids (SS), SS/TA relationship and ascorbic acid content. An increase (p ≤ 0.05) of the variables: fresh weight, DL, DT and juice yield, in both experiments, was observed, while the color parameters of pH, L* and C* increased only in the first and SS in the second. Already, the variables chlorophyll and firmness of the peel decreased significantly, in both experiments, whereas the color parameter h* and ascorbic acid content decreased only in the first experiment and thickness of the peel, only the second. Thus, the end of the study of the development of lemons, it is concluded that the fruits were able to be picked at its optimum stage to harvest maturity after 77º days.<br>O estado do Ceará vem ganhando atenção como um Estado emergente na produção de frutos no país. Limões ‘Sicilianos’, tradicionalmente cultivados no sul, vem sendo plantados nesta região, no entanto, ainda não existem muitas informações sobre a qualidade destes frutos cultivados localmente. O limão ‘Siciliano’ híbrido ‘Eureka’ é um fruto não-climatérico, devendo ser colhido, comprado e comercializado com seus atributos de qualidade relacionados ao sabor ideal para o consumo. O trabalho objetivou a determinação do estádio de maturação apropriado do limão ‘Siciliano’ por ocasião da colheita através de medições periódicas físicas e físico-químicas durante o desenvolvimento e crescimento do fruto. Foram realizados dois experimentos, acompanhando duas floradas distintas. As quatro primeiras colheitas foram realizadas a cada 15 dias e a partir do 49° dia, as colheitas passaram a ser a cada 7 dias até o 91° dia sendo, assim, realizado um total de 11 colheitas nos tempos 0, 14, 28, 42, 49, 56, 63, 70, 77, 84 e 91 dias para cada experimento. Em cada tempo, foram colhidos um total de 20 frutos que foram divididos em grupos de 4, constituindo assim, cinco repetições. O primeiro experimento foi realizado nos meses de outubro de 2012 a janeiro de 2013 e o segundo nos meses de julho a outubro de 2013. Os frutos foram avaliados quanto às características físicas e físico-químicas: massa fresca, diâmetros longitudinais e transversais (DL/DT), índice de formato, firmeza da casca, rendimento de suco, espessura da casca, cor (h*, C* e L*), conteúdo de clorofila da casca, pH, acidez titulável (AT), sólidos solúveis (SS), relação SS/AT e teor de ácido ascórbico. Foi observado um aumento (p≤0,05) das variáveis: massa, DL, DT e rendimento de suco, nos dois experimentos, enquanto os parâmetros de pH, cor C* e L* aumentaram apenas no primeiro e SS, no segundo. Já, as variáveis firmeza e clorofila da casca reduziram significativamente nos dois experimentos, ao passo que o parâmetro de cor h* e o teor de ácido ascórbico reduziram apenas no primeiro experimento e a espessura da casca, apenas no segundo. Dessa forma, ao final do estudo do desenvolvimento dos limões sicilianos, conclui-se que, os frutos estavam aptos a serem colhidos em seu estádio ótimo de maturação à colheita no 77º dia.

Tyrimo tikslas: Veiksnių, įtakojančių kineziterapijos efektyvumą, sergantiesiems GSI, ankstyvuoju ligos laikotarpiu, nustatymas. Kontingentas. Tyrimas buvo atliktas Kauno medicinos universiteto klinikų (KMUK) neurologijos skyriuje. Tyrime dalyvavo 25 ligoniai (17 moterų ir 8 vyrai), kuriems buvo diagnozuotas išeminis galvos smegenų insultas, ūmus ligos laikotarpis. Reabilitologas buvo paskyręs kineziterapiją. Tyrimas buvo atliekamas 2007 m. spalio – 2008 kovo mėn. Pacientai vidutiniškai skyriuje praleido 14 dienų. Tiriamieji buvo suskirstyti į keletą grupių: pagal lytį – vyrai ir moterys, pagal amžių – 50-69 bei 70-87 metų, bei pagal galvos smegenų pusrutulio pažeidimo pusę – kairės ir dešinės. Tyrimo metodai. Reabilitacijos veiksmingumui vertinti pasirinkta paciento bendros funkcinės būklės ( Bartelio indeksas), motorinės funkcijos (Rivermedo judesių įvertinimo skalė), bei pažintinių funkcijų (Trumpas protinės būklės tyrimo testas) pokytis po reabilitacijos. Tyrimo rezultatai parodė, kad ankstyva sergančiųjų galvos smegenų insultu kineziterapija statistiškai reikšmingai pagerino pacientų bendrąją funkcinę būklę, motorinę funkciją bei pažintines funkcijas visose grupėse (pagal amžių, lytį ir galvos smegenų pažeidimo pusę)(p<0,05). Tačiau statistiškai reikšminga lyties, amžiaus, bei galvos smegenų pažeidimo pusės įtaka bendrai funkcinei būklei, motorinei, bei pažintinėms funkcijoms nenustatyta, kaip manoma dėl mažo tiriamųjų skaičiaus.<br>Aim of the research: Establishment of factors influencing the effectiveness of physiotherapy of people sick with stroke in the early period of illness.

Full textAbstract:
Limb salvage in patients with advanced peripheral vascular disease or effective nonoperative therapy for patients with limited disease still remains a challenge in modern vascular surgery. Based on recent advances in the area of angiogenesis as well as our previous studies of alternative approaches for limb ischemia, we have presented herein the step-by-step experimental investigations that are directed toward the development of a novel therapy, angiogenic stimulation, for the revascularization of ischemic limbs. An animal ischemic hindlimb model has been developed suitable for testing our hypothesis and further understanding of this potential therapy. We have demonstrated that an angiogenic factor, ECGF, when administered intramuscularly into the ischemic limb, markedly enhances revascularization of the limb in the models of unilateral as well as bilateral hindlimb ischemia. In addition, we have also demonstrated that the angiogenic effect of ECGF is dose dependent and is demonstrable only when it is administered directly into the limb in the presence of ischemia. Therefore, we conclude that angiogenic therapy may have the potential for the treatment of patients with chronic limb ischemia.

Full textAbstract:
This is a biography of Robert Jones, 1857-1933. He was a surgeon, and is credited with bringing orthopaedics from its quack past into its scientific present. This work explores Jones’ life and times, and examines whether he is entitled to the epithet ‘father of orthopaedics’. It looks at the history of bonesetting, the influences on Jones’ development and medical training, and some key moments in his career – notably his involvement in the building of the Manchester Ship Canal, the planning of Heswall Children’s Hospital, and the Great War. It argues that although there are other medical men who could have been credited with fathering orthopaedics, he is indeed the father – at least of orthopaedics in Britain, if not internationally. This version of Jones’ life begins with something of his biographer’s journey, before it explores what and who influenced Jones, and in turn what his legacy has been to the medical profession. The accompanying Critical Commentary explores whether or not it is possible to offer a definition of biography as a genre in the light of its history and purpose. It examines critical views, considers the mythology that grows up around historical figures, and also explains the rationale for the structure chosen for organising the material presented in this new biography of Robert Jones, Live and Limbs: Re-membering Robert Jones.
