Optimisation Of Agrobacterium Mediated Gene Transfer And Micrografting Systems In Lentil (lens Culinaris Medik)

Kamci, Hamdi 01 September 2004 (has links) (PDF)
In this work Agrobacterium (KYRT1::pTJK136) mediated gene transfer to lentil (Lens culinaris Medik.) embriyo apex and regeneration through micro-grafting in lentil was studied. In micro-grafting two different types root stock stem height and root stock preparations were optimized. According to the results half stem length was found to be more successful then the full. Also lentil root stock was more successful then the chickpea root stock. The types of root stock preparations studied were designated as Z and M. The Z type root stock was superior then the M type, when the micro-grafting, hardening and green-house stages were concerned. In study of Agrobacterium mediated gene transfer to lentil embryo apex the effect of the following parameters on the transformation efficiency were addressed / type and intensity of injury, type of pre-incubation media for injured explants, effect of evacuation, effect of L-cysteine during co-cultivation and Agrobacterium incubation duration. According to the results crushing type of injury was superior over the poking and sonication type of injuries. Following the injury Hogland`s solution was used as pre-incubation media prior to infection. The effect of evacuation parameter was found to be insignificant whereas the effect of L-cysteine during co-cultivation was negative on the transformation efficiency. According to the Agrobacterium incubation duration studies, 240 minutes, followed by 120 minutes of Agrobacterium incubation were the most efficient in terms of transformation efficiency. However, since there was no significant difference among the two 120 minutes chosen to be the optimum bacterial incubation duration.

Anàlisi dels factors d'optimització dels resultats d'un Banc d'Ossos Regional

Segur Vilalta, Josep M. 28 July 1995 (has links)
Un Banc d'Ossos és la organització encarregada de la selecció de donants, obtención, processament, emmagatzemament i distribució d'al.loempelts d'aparell locomotor per a la seva posterior utilització mèdica. El principi bàsic és obtenir teixit segur i eficaç per als pacients. Un al.loempelt és aquell empelt realitzat entre individus de la mateixa espècie. però amb genotip diferent. La difusió dels al.loempelts ossis es va iniciar amb Inclan (1942), qui publicà la primera gran sèrie utilitzant ossos conservats per a un període de fins dos mesos. A França, Andrè Sicard estableix al 1946 una "reserva d'empelts" a l'Hospital de Beaujon. El centre més important d'utilització dels al.loempelts, però, ha estat als Estats Units de l'Amèrica del Nord. Mankin inicia l'any 1971, a l'Hospital General de Massachussets, una llarga sèrie de resseccions tumorals amb substitució per empelts massius obtinguts de cadàvers i congelats a -80º. També als Estats Units, Malinin (1976), a la Universitat de Miami, inicia una llarga sèrie de més de 900 al.loempelts massius, obtinguts de cadàvers i conservats en nitrògen líquid, a -150°. A fi d'unificar criteris i crear unes normes, el Consell Musculoesquelètic de la Societat Americana de Bancs de Teixits (AATB) publica la primera guia el 1979 per als bancs de teixits musculoesquelètics. Als Estats Units hi ha actualment 220.000 receptors anuals d'al.loempelts ossis o de parts toves, que provénen de 5000 donants/any. A Europa, de manera semblant a l'AATB dels Estats Units apareixen la Societat Europea de Bancs de Teixits (EATB) l'any 1991 i la Societat Europea de Transplantament Musculo-esquelètic (EAMST) l'any 1992. L'any 1951 es crea el primer banc d'ossos d'Espanya a l'Hospital Provincial de Madrid (Sanchis Olmos, 1953). Poc després, l'any 1953, es constitueix per Ordre Ministerial el Banco Nacional de Huesos (González Sánchez 1956). Els primers Bancs d'ossos que segueixen la metodologia establerta per l' AATB i els grans bancs americans sorgeixen en la dècada dels vuitanta. L'any 1992 L'Organización Nacional de Trasplantes (ONT) publica unes recananacions per unificar els criteris de funcionament dels bancs d'ossos a Espanya. Per a la realització d’aquesta tesi doctoral s'han valorat els 53 donants multiorganics generats per l'Hospital Clínic de Barcelona i per altres centres coordinats amb aquest, des del desembre de 1987 fins al desembre de 1992, dels quals s'ha practicat l'extracció de teixit esquelètic. El nombre total d'ossos obtinguts ha estat 270, i el d' al.loempelts 475. Els paràmetres estudiats han estat els següents: edat i sexe del donant, causa de mort, hospital d’extracció, equips extractors d'altres òrgans i teixits previs, nombre de membres de l'equip extractor de teixit esquelètic, tipus d’os, cultiu de l’os a l'extracció, fragmentació, tipus de fragment, cultiu del fragment, temps d'emmagatzemament, centre d'implantació, diagnòstic del receptor, cultiu del al.loempelt i del llit receptor, i resultat clínic i radiològic de l' empelt. L’objectiu general d’aquesta tesi és optimitzar el funcionament, el rendiment i els resultats d'un Banc d’Ossos que anomenem "Regional", és a dir, que obté els al.loempelts esquelètics de donants multiorgànics i tissulars, en contraposició als Bancs d’Ossos quirúrgics, que es nodreixen bàsicament de caps de fèmur. Per obtenir aquest objectiu general hem establert els següents objectius particulars: (1) Avaluació dels factors que poden ser significatius en el resultat dels cultius realitzats en els ossos després de la seva obtenció: I’hospital d'extracció, les extraccions prèvies d'òrgans I eixits, el nombre d'equips extractors previs, el nombre de membres de l'equip extractor de teixit esquelètic, la causa de mort, l'edat i el sexe del donant, i el tipus d'os obtingut. (2) Valoració de les possibles causes de contaminació dels al.loempelts obtinguts després de la fragmentació dels ossos, analitzant l’os d'origen i el tipus de fragment. (3) Anàlisi de la distribució geogràfica dels centres en els quals s'implanten els empelts generats pel Banc d'Ossos de l'Hospital Clínic, i el nivell d'utilització dels diversos tipus de fragments. (4) Examen dels diferents paràmetres que poden determinar el comportament dels al.loempelts: edat i sexe del donant, tipus d'os d'origen, tipus de fragment, temps d'emmagatzemament, cultiu de l'al.loempelt, cultiu del llit receptor, i tipus d'intervenció. Les conclusions són: (1) Els factors que s'han mostrat determinants en la contaminació dels ossos obtinguts de donants multiorgànics són: l'hospital d’extracció (menys mltius positius en els ossos obtinguts a l'hospital on està ubicat el Banc amb relació als explantats en un altre centre), i el nombre de membres de l'equip extractor d’aparell locomotor (més contaminació quan hi ha 4 o més membres). (2) Les extraccions prèvies dels diferents òrgans i teixits, el nombre d'equips extractors previs a l'obtenció del teixit esquelètic, la causa de mort, l'edat i el sexe del donant, i el tipus d’os, no han presentat diferències significatives en la contaminació dels ossos obtinguts de donants multiorgànics. (3) Justifiquem la fragmentació dels ossos obtinguts, realitzada en condicions adequades, pel baix percentatge de contaminació dels segments, amb relació al benefici que aporta, ja que permet que més receptors puguin gaudir dels avantatges dels al.loempelts. (4) L'evolució cronclògica ha estat un factor determinant en la diferent distribució geogràfica de la utilització dels al.loempelts generats pel Banc d'Ossos de l'Hospital Clínic, i s'ha convertit en la pròpia d'un Banc regional. (5) El tipus d'al.loempelt més sol.licitat i utilitzat és el fragment esponjós. (6) El temps d' emnagatzernament, amb un mètode de conservació i d'embalatge idonis, no és un factor determinant en la contaminació dels al.loempelts, i quant més prolongat és, menors són les complicacions dels implants. (7) El millor resultat de les osteotomies metafisàries d‘addició per un costat i l'augment de les complicacions en les fractures obertes i les artrodesis lumbars per l’altra, indiquen que la qualitat del llit receptor i les condiciones biomecàniques són altres determinants en el comportament dels al.loempelts. (8) L'edat i el sexe del donant (amb una adequada selecció), el tipus d'os i de fragment (amb una correcta indicació), els cultius de l'al.loempelt i del receptor, i la resta d’indicacions analitzades no són determinants en l'aparició de complicacions del comportament dels al.loempelts. / The general term for the activities of donor screening, retrieval, processing, storage and distribution of bone allografts is “Bone Banking". The Hospital Clínic of Barcelona Bone Bank was instituted in 1987. From December 1987 to December 1992 a total of 475 bone allografts were obtained of 270 bones; they belonged to 53 donors, all of them multi-organic or tissular donors. The grafts were obtained under strictly aseptic conditions and bacteriological cultures were performed of each bone. The grafts were packed in two sterile plastic bags and then stored by freezing in electrical freezers (-40°C / -80°C). The parameters studied have been: age and sex of the donor, cause of death, hospital of extraction, number of persons of the bone procurement team, previous organ procurements from the same donor, type of bone, culture of the bone, fragmentation, type of fragment, culture of the fragment, time of storage, hospital of implantation, diagnostic of the recipient, culture of the allograft, culture of the recipient bed, and clinical and radiographic results of the allograft. The aim of this thesis is to optimize the results of a Regional Bone Bank. The conclusions are: (1) Number of contaminated bones has been significantly higher in extractions outside of the main hospital, and in the procurements with more than 4 team members. (2) The age and sex of the donor, the cause of death, the number of previous organ procurements from the same donor and the type of bone weren't determinative factors contributing to bacterial contamination of the bones. (3) We justify fragmentation of the obtained bones. (4) The chronological evolution has been a determinative factor of the different distribution of the allogratts of the Hospital Clínic Bone Bank. (5) Cancellous allograft is the type of fragment more implant. (6) Lang time of storage is a determinative factor to decrease de number of complications of the allografts. (7) Addition osteotomies have shown the best results of the bone allografts, and exposed fractures and lumbar arthrodeses the worst. (8) Age and sex of the donor, type of fragment, cultures of the allograft and the recipient bed aren’t determinative factors in the clinical and radiographic results of the bone allografts.

Annuum, two of C. baccatum and one of C. frutescens, and of ten commercial pepper cultivars; 3 - resistance to M. javanica and M. mayaguensis in genotypes resistant to M. incognita; 4 - compatibility of grafting of genotypes resistant to M. incognita with the bell pepper hybrids Rubia R, Margarita and Maximos, during seedling, growth and productive phases; and 5 - maintenance of resistance of rootstocks to M. incognita at the end of the cultivation cycle. The experiments studying water sprinkling and letting suspensions stand were conducted in the Nematology Laboratory of UNESP-FCAV, at Jaboticabal-SP, during 2004. In nematode application with water sprinkling, the roots of Capsicum spp. were triturated, and the suspensions were poured over a sieve with a pore size of 0.074 mm (200 mesh) on top of a sieve with a pore size of 0.025 mm (500 mesh) and washed; the foam retained on the eggs and juveniles on the 500-mesh was sprinkled or not using 50 mL of water. In the experiment of letting suspensions stand, after trituration the suspensions were allowed to stand for the periods established, after which they were poured over the sieves and washed. The experiments on the resistance of Capsicum spp. to Meloidogyne spp., the compatibility of grafting and the maintenance of resistance to root-knot nematodes were conducted in a greenhouse, at Jaboticabal-SP, between 2004 and 2005. In experiments on resistance of the genotypes to Meloidogyne spp., ten plants were used per genotype, where each plant was considered a repetition...

Os materiais híbridos orgânico-inorgânicos apresentam propriedades distintas que não se limitam à soma das propriedades de seus componentes separadamente, mas decorre de um sinergismo entre as fases em nível molecular. Como uma vertente do estudo desses materiais, a modificação de superfícies de argilas minerais se tornou uma forma de melhorar ou criar novas propriedades em materiais híbridos. Um exemplo é o método grafting, que consiste na reação de superfície entre argila e a matriz polimérica. Para tornar compatível a fase orgânica (polímero) e a fase inorgânica (argila) é necessário um agente funcionalizante, no caso, foi usado o TMSM (trimetoxisilil propil metacrilato) ligado a argila por reações com os grupos silanóis/Si-OH. O objetivo é aprimorar a síntese de materiais híbridos orgânico-inorgânicos utilizando o método grafting, sendo a fase orgânica o polímero termoplástico poli(metil metacrilato) (PMMA) e a fase inorgânica será as argilas derivadas da montmorilonita (Cloisite® 15A e Cloisite® 93A) já previamente funcionalizadas com TMSM. A comparação do conjunto de nanocompósitos permitiu analisar a evolução das propriedades térmicas, em como as baixas quantidades de argila em escala nanométrica presentes na matriz polimérica pode influenciar na estabilidade térmica do PMMA. A evolução das propriedades térmicas foi analisada por meio de técnicas experimentais de TG e DSC. Os nanocompósitos foram caracterizados por DRX, FTIR, SAXS, MEV e RMN. O presente trabalho mostrou que há estabilização térmica apenas do TMSM e do percussor argila-TMSM em comparação aos nanocompósitos antes do tratamento térmico. E que com o tratamento térmico dos nanocompósitos há uma maior estabilização em relação ao polímero, onde a argila funciona como uma barreira de difusão dos gases formados na reação de decomposição do polímero. Os dados de caracterização mostram que a funcionalização ocorreu de maneira eficaz. Uma análise das propriedades ópticas e elétricas da argila montmorilonita foi feita por cálculos teóricos baseado na Teoria do Funcional da Densidade (DFT). Os resultados mostraram a influência do Fe2+ no band gap do material e consequentemente uma menor tendência isolante da argila. / The challenge of the production and application of polymer nanocomposites has been receiving great scientific attention due to its multifunctional character. The organic-inorganic hybrid materials have distinct properties that are not limited to the sum of the properties of their components separately, but derive from a synergism between the phases at the molecular level. As an aspect of the study of these materials, the surface modification of clay minerals has become a way to improve or create new properties in hybrid materials. An example is the grafting method, which consists of the surface reaction between clay and the polymer matrix. In order to make the organic phase (polymer) and the inorganic phase (clay) compatible, a functionalizing agent is required; in this case, the TMSM (trimethoxysilyl propyl methacrylate) bound to clay was used by reactions with the silanols / Si-OH groups. The aim is to improve the synthesis of organic-inorganic hybrid materials using the grafting method, the organic phase being the thermoplastic polymer poly (methyl methacrylate) (PMMA) and the inorganic phase will be clays derived from montmorillonite (Cloisite® 15A and Cloisite® 93A) previously functionalized with TMSM. The comparison of the number of nanocomposites allowed to analyze the evolution of the thermal properties, such as low amounts of clay at the nanoscale present in the polymer matrix can influence the thermal stability of PMMA. The evolution of the thermal properties were analyzed by TGA and DSC experimental techniques. The nanocomposites were characterized by XRD, FTIR, SAXS, SEM and NMR. The present work showed that there is only thermal stabilization of the TMSM and the clay-TMSM precursor in comparison to the nanocomposites before the heat treatment. And after the heat treatment of the nanocomposites there is a greater stability in relation to the polymer, in which the clay acts as a diffusion barrier gas formed in the decomposition reaction of the polymer. The characterization data show that functionalization occurred effectively. An analysis of the optical and electrical properties of montmorillonite clay was made by theoretical calculations based on the Density Functional Theory (DFT). The results showed the influence of Fe2+ on the band gap of the material and consequently a lower insulating tendency of the clay.

No. of bitstreams: 1 RoseanoMS_DISSERT.pdf: 998724 bytes, checksum: 0dca9ffcac3f9ed7130eddfb95d703e7 (MD5) Previous issue date: 2012-09-18 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The objective of this study was to evaluate the combination of three forms of grafting methods and use of protective grafting with moist chamber in the production of yellow passion fruit seedlings. The experimental design was a randomized complete block in a 3x2 factorial arrangement with six replications, each plot consisting of nine plants, where the factors were the combinations of three embodiments of the method of grafting (cleft, side slit and simple slot) with the use of grafting protection with moist chamber or not using it. Seeds from FB 100 passion fruit cultivar were used for production of rootstock plants. On the other hand, seeds from the rounded-yellow cultivar (Topseed® Company) were used for production of scions. Grafting were performed 70 days after sowing. After 21 days, grafts were removed from the protection of the moisture chamber. At this time, the effectiveness of grafts was evaluated. At 28, 42 and 56 days after grafting it was evaluated the amount of plants remained alive. Fifty six days after grafting it was evaluated the number of leaves, graft and rootstock diameter, plant height and shoot dry weight. There was a significant interaction for different types of grafting and use of moist chamber at 21 days after grafting. Types of grafting with the highest percentage of graft effectiveness were: cleft (94.45%) and side slit (91.67%). There was no influence on the use of protection with moist chamber for cleft and side slit. Cleft type grafting showed a decrease in the rate of fixation when not using moist chamber protection. Cleft grafting and side slit showed the higher rates of survival with 86.12% and 91.67% respectively for the 28, 42 and 56 days after grafting. Plants from grafts protected with moist chamber had the highest average survival percentage (79.63%) for 28, 42 and 56 days after grafting. The use of moist chamber caused a decrease in plant growth showing that there is a need for plants to remain in it much less than the used in the trial. Cleft and side slit grafting types associated with the use of protection promoted by moist chamber lowest rates of fixation and survival of seedlings of yellow passion / O objetivo deste trabalho foi avaliar a combinação de três formas de realização da enxertia pelo método de garfagem e uso da proteção da enxertia com câmara úmida na a produção de mudas de maracujazeiro-amarelo. O delineamento experimental adotado foi o de blocos completos casualizados em esquema fatorial 3x2, com seis repetições, sendo cada parcela constituída de nove plantas, onde os fatores foram as combinações de três formas de realização da enxertia pelo método de garfagem (fenda cheia, fenda lateral e fenda simples) e utilização e não do uso da proteção da enxertia com câmara úmida. Para produção das mudas dos porta-enxertos e enxertos foram utilizadas sementes da cultivar FB 100 e redondo-amarelo da marca comercial Topseed® respectivamente. As enxertias foram realizadas aos 70 dias após a semeadura. Aos 21 dias após as enxertias foram retiradas as proteções por câmara úmida e avaliado a porcentagem de pegamento. Aos 28, 42 e 56 dias após a enxertia foi avaliado a sobrevivência em porcentagem de plantas que permaneceram vivas. Aos 56 dias após a enxertia avaliou-se o número de folhas, diâmetro do enxerto e porta-enxerto, altura da planta e massa seca da parte aérea. Verificou-se interação significativa para os diferentes tipos de enxertia e uso da câmara úmida aos 21 dias após a enxertia, os tipos de enxertia que apresentaram as maiores porcentagem de pegamento foram: fenda cheia (94,45%) e fenda lateral (91,67%). Não houve influência do uso da proteção com câmara úmida para as enxertias tipo fenda cheia e lateral. Com a realização da enxertia do tipo fenda simples, verificou-se diminuição da taxa de pegamento quando não se utiliza a proteção. Os tipos de enxertia por fenda cheia e fenda lateral apresentaram os maiores índices de sobrevivência e permaneceram em 86,12% e 91,67% respectivamente para os 28, 42 e 56 dias após a enxertia. As plantas provenientes de enxertos protegidos com câmara úmida apresentaram a maior média de porcentagem de sobrevivência (79,63%) para os 28, 42 e 56 dias após a enxertia. O uso da câmara úmida promoveu um decréscimo no crescimento das plantas, sendo necessário um menor tempo de permanência da proteção sobre as plantas. As enxertias de garfagem tipo fenda cheia e lateral associadas ao uso da proteção com câmara úmida promoveram os melhores índices de pegamento e sobrevivência das mudas de maracujazeiro-amarelo
