Full textA number of types of molecular polymorphisms can be used for studying genetic relationship and evolutionary history. Microsatellites are hypervariable and can be very useful tools to determine population structure, distinguish sibling species, as well as verifying parental relationships and pedigrees. However, while microsatellite polymorphisms are useful for solving relationships between populations within a species, relations among species or genera will probably be obscured due to a high degree of homoplasy —identity arising from evolutionary convergence not by descent. For long range evolutionary history, such as phylogeny from old world monkey to human, mtDNA markers may be better candidates. The aim of this thesis is to assess molecular polymorphisms of different types and their optimal use in different situations. Two widely separated taxa were used for testing –the green monkey Chlorocebus sabaeus, and the sibling dipteran flies Bactrocera tryoni and B. neohumeralis, known collectively as the Queensland fruit fly. In the present study a complete 16,550 bp mtDNA sequence of the green monkey Chlorocebus sabaeus is reported for the fist time and has been annotated (Chapter 2). Knowledge of the mtDNA genome contributes not only to identification of large scale single nucleotide polymorphisms (SNPs) (Chapter 4) or other mtDNA polymorphisms development, but also to primate phylogenetic and evolutionary study (Chapter 3). Microsatellites used for the green monkey paternity and pedigree studies were developed by cross-amplification using human primers (Chapter 5). For studies of population structure and species discrimination in Queensland fruit fly (Chapter 7), microsatellites were isolated from a genomic library of Bactrocera tryoni (Chapter 6) The total length of 16550 bp of complete mtDNA of the green monkey C. sabaeus, which has been sequenced and annotated here, adds a new node to the primate phylogenetic tree, and creates great opportunity for SNP marker development. The heteroplasmic region was cloned and five different sequences from a single individual were obtained; the implication of this are discussed. The phylogenetic tree reconstructed using the complete mtDNA sequence of C. sabaeus and other primates was used to solve controversial taxonomic status of C. sabaeus. Phylogenies of primate evolution using different genes from mtDNA are discussed. Primate evolutionary trees using different substitution types are compared and the phylogenetic trees constructed using transversions for the complete mtDNA were found close to preconceived expectations than those with transversions + transitions. The sequence of C. sabaeus 12SrRNA reported here agrees with the one published by ven der Kuyl et al. (1996), but additional SNPs were identified. SNPs for other regions of mtDNA were explored using dHPLC. Twenty two PCR segments for 96 individuals were tested by dHPLC. Fifty five SNPs were found and 10 haplogroups were established. Microsatellite markers were used to construct a genealogy for a colony of green monkeys (C. sabaeus) in the UCLA Vervet Monkey Research Colony. Sixteen microsatellites cross-amplified from human primers were used to conduct paternity analysis and pedigree construction. Seventy-eight out of 417 offspring were assigned paternity successfully. The low success rate is attributed to a certain proportion of mismatches between mothers and offspring; the fact that not all candidate fathers were sampled, the limitations of microsatellite polymorphisms; and weakness of the exclusion method for paternity assessment. Due to the low success rate, the pedigree is split into a few small ones. In a complicated pedigree composed of 75 animals and up to four generations with multiple links a power male mated with 8 females and contributed 10 offspring to the pedigree. Close inbreeding was avoided. Population structure within two species of Queensland fruit fly Bactrocera tryoni and Bactrocera neohumeralis (Tephritidae: Diptera) is examined using microsatellite polymorphisms. Queensland fruit flies B. tryoni and B. neohumeralis are sympatric sibling species that have similar morphological and ecological features. They even share polymorphism at the molecular level. Mating time difference is the main mechanism by which they maintain separate species. In the present study, 22 polymorphic and scorable microsatellites were isolated from B. tryoni and tested in the two species sampled from sympatric distribution areas. Pairwise genetic distance analysis showed explicit differentiation in allele frequencies between the two species, but very weak differences between conspecific populations. Gene flow is higher within B. tryoni than within B. neohumeralis, and gene exchange between the two species exists. An averaging linkage clustering tree constructed by UPGMA showed two major clusters distinguishing the two species, and it appears that population structure is highly correlated with geographic distance. The relationship between molecular markers, evolution, and selection are discussed using comparative studies within two large taxa: primate and insect. The degree of conservation and polymorphism in microsatellites varies between taxa, over evolutionary time.

Full textIn the use of dental implants have been proposed new techniques, such as the placement immediately after extraction implants, immediate temporization and immediate loading, which implies a change in traditional protocols in the work of Brånemark. The use of dental implants to restore the natural function and beauty after the loss of a tooth has become one of the biggest challenges of restorative dentistry. The placement of dental implants immediately became an integral part of a protocol designed to maintain a harmonious gingival contour. Although the literature shows the position and timing of immediate implants placed in post-extraction sockets do not offer definitive conclusions, the wide number of clinical studies show that the results are similar to those reported for the successful placement of conventional technique. The immediate timing is now a reality in implantology, but its success depends on the careful selection of the case, a deep understanding of biological principles, precision-prosthetic surgical maneuvers and to respect the biological principles of bone repair. Several studies have reported high success rates after the temporary restoration of implants placed immediately after tooth extraction and implants placed in healed bone. Besides eliminating the need for a temporary removable implant, this technique has also demonstrated the potential preserving existing bone and gingival architecture. The objective of this study was to evaluate the survival rate and the loss of interproximal bone crest of 43 implants Tryon® subjected to immediate temporization. The study group consisted in 43 patients of both sexes with the need to rehabilitate the absence of a single tooth. The implants were placed in the anterior and posterior regions of both maxillary. On the alveolar ridge (34 implants), and immediately after extraction (8 implants). All implants received a minimum insertion torque of 40N/cm2 and were followed by six months. Radiographs realized with a parallel technique studied the crestal bone loss. They were analyzed using the software Adobe Photoshop. In our study, the implant Tryon® had a 88.4% success rate. The level of mesial bone crest showed a significant loss of height, from 0.458 ± 0.932 mm to 0.907 ± 0.525 mm (3months) and 1.313 ± 0.678 (6 months; p <0.001).The level of distal bone crest decreased significantly of 0.232 ± 0.373 mm to 0.729 ± 0.594 mm (3 months) and 1.197 ± 0.677 mm (6 months; p <0.001). The larger diameter and the highest plaque index rate showed a significant negative correlation index with bone loss in mesial at 3 and 6 months. The length and the insertion torque showed no significant correlation with bone level achieved. The sex of the patients, the bone density, the implant placement in bone healed or in post extraction socket, the anterior or posterior position of the implant in the maxilla or mandible, are variables that did not influence significantly the mesial and distal bone loss. In implants placed immediately after extraction or bone healed subject to immediate temporization, may have predictable results taking into account the implant survival rate, and similar interproximal reabsorption standards to implants with deferred temporization.

Full textThis project aims to promote the involvement of community pharmacists in clinical research. In the last years, the pharmaceutical profession has gone through various challenges. At the same time, pharmacists have sought to develop a more active role in the community. The skills that pharmacists have allow them a more active role in clinical research, either cooperating with health units, either as researchers. The proximity to the patient and the placing in the community, allows community pharmacies to have an important role in the disclosure of clinical research. The Portuguese reality, so far, does not seem to reflect the reality of other countries in this field. However, Portugal has the necessary conditions for this situation to change. The growing importance of real world data and the placement of pharmacies in the community leave space for its involvement in clinical research to be improved. Thus, in the near future it would be important that community pharmacies are called upon to this reality. This project suggests the application of a questionnaire to Portuguese community pharmacies in order to assess the feasibility of this project, evaluating their interest in clinical research and identifying the possible barriers to their participation.
Este projeto propõe-se promover o envolvimento dos farmacêuticos de farmácia comunitária em investigação clínica. Nos últimos anos, a profissão farmacêutica tem passado por vários desafios. Ao mesmo tempo, os farmacêuticos têm procurado desenvolver um papel mais interventivo na comunidade. As competências que os farmacêuticos têm permitem-lhes um papel mais interventivo em investigação clínica, quer cooperando com as unidades de saúde, quer como investigadores. A proximidade ao utente e a inserção na comunidade, permite às farmácias comunitárias terem um papel importante em investigação clínica. A realidade portuguesa, até ao momento, não parece acompanhar a realidade doutros países neste âmbito. No entanto, Portugal reúne as condições necessárias para que essa realidade se altere. A crescente importância dos dados de vida real e o posicionamento das farmácias na comunidade deixam espaço para que a sua intervenção em investigação clínica possa ser melhorada. Assim, num futuro próximo será importante que as farmácias comunitárias sejam chamadas para esta realidade. Este projeto sugere a aplicação futura de um questionário de modo a avaliar a sua exequibilidade, avaliando o interesse das farmácias comunitárias portuguesas em investigação clínica e as possíveis barreiras à sua participação.

This study examined organizational routines and teachers' experiences in two urban public elementary schools. The study advances the scholarship on teachers' work through a nuanced examination of instructional routines in order to illuminate teachers' experiences with accountability based-reforms. Using neoinstitutional theory, this study employed ethnographic methods to examine instructional routines in two schools of varying AYP-status: one high-performing school and one low-performing school. Observations and interviews were conducted with a total of 17 teachers over the course of two school years. Findings indicated that routines were a recoupling mechanism, used to more closely align teachers' tasks with the goals of accountability policy. The implementation and performance of routines was both similar and distinct between the two schools. There were distinct differences in the intensity and the pervasiveness of mandated instructional routines between schools. However, regardless of AYP-status, routines served to rationalize teachers' instructional tasks by reducing variation in the form and content of classroom instruction. Accordingly, the process of recoupling and the resulting rationalization of teachers' tasks resulted in teachers experiencing reduced professional discretion, depleted intrinsic rewards, and compromised relationships with students and with each other. Under these circumstances, accountability policy moved teaching away from professionalization and undermined efforts to sustain teachers over time.

Full textAdjuvant effect of Ginkgo biloba Extract on Immune Response to Bovine Serum Albumin in Chickens and Rabbits Adjuvants are inorganic or organic compounds that stimulate the immune system and increase the response to a given antigen without having any specific antigenic effect in itself. They are often included in vaccines to enhance the recipient's immune response to a supplied antigen. In present study we evaluated the adjuvant capacity of a plant Ginkgo biloba (GB) extract upon the mucosal immunization of rabbits and hens with bovine serum albumin. Adjuvant efficacy was evaluated by measuring the titres of IgA in saliva, IgG and IgM immunoglobulins in serum of the animals and IgY in chicken egg yolk. Animals immunized using GB adjuvant showed strong cellular (IgA-based) and humoral (IgG and IgM) immune responses when compared to immunisations without adjuvant. It also became clear that the the immune response using Freund’s adjuvant was highest in humoral immune response. GB extract induced more important immune response in chickens when compared to rabbits as measured by IgA titres. The titres of IgG in hens and rabbits were found to be at similar levels and their production remained stable during 8 weeks. The levels of IgY were evaluated in chicken egg yolk and appeared stable over time thus resembling the IgG response. Different from IgA and IgY, the detectable levels of IgM in hens were observed after second GB extract-based immunisation, while IgA and IgY... [to full text]

Full textBackground: Business models which integrates sustainability in their business becomes more common today. For new business venture capital is often an attractive financing alternative and therefor constitutes a significant role as an enabler for these businesses. The question is how venture capital firms in their risk assessment evaluate these startups. Purpose: This study aims to contribute to an increased understanding of venture capital firms risk assessment. Furthermore, the purpose of this study is to examine how venture capital firms evaluate startups with product as a service in their risk assessment. Completion: This study is of a qualitative structure with an abductive approach that builds on four interviews from four different venture capital firms. The interviewees all work in firms that invest venture capital in startups. They have been chosen to gain insight in the riskassessment of venture capital firms. Value drivers and financial barriers related to PaaS have been applied to the risk assessment that the interviewees have described. Conclusion: The paper shows that venture capital firms does not have a specific riskassessment for companies with a higher grade of sustainability, instead they are assessed on the same basis as traditional business models. PST can however, with its value drivers and financial barriers, display both strengths and weaknesses in the risk assessment conducted by venture capital firms.
