    As Chapter 1 briefly outlined, Kenya has a strong and long-standing pharmaceutical industry. A 2015 Business Monitor report on pharmaceutical manufacturing in Kenya states that the country hosts the largest pharmaceutical industrial base in East Africa. The report also sees a bright future as a ‘potential base for export across East Africa’ (BMI Research, 2015). This chapter locates the Kenyan pharmaceutical industry within the country’s historical context of industrial development and growth

    Get PDF
    Objectives: A research project on occupational exposure in relation to oral carcinoma was periodic compulsory check-ups, oral examinations were performed to detect pathologies and the prevalence of potentially neoplastic oral conditions and a selfassessment questionnaire was administered to all of the subjects. The questionnaire was structured to collect information regarding demographic and clinical characteristics, risk habits (tobacco and alcohol consumption) and oral health habits, and to allow an assessment of knowledge about oral cancer, related risk factors and early signs. Results: The study cohort included people with different ethnicities, and there were significant differences in clinical characteristics between Italians and other Europeans. The subjects showed a good knowledge about oral cancer and related risk factors (with correct answers provided to >50% of the questions) but insufficient knowledge about the early signs of oral carcinoma (correct-answer rates of 16–42%). There were high rates of habits that are potentially harmful to oral health, such as smoking (43.8%) and alcohol consumption (57%). The daily habit of brushing teeth was present in 92.6% of the subjects, but they had a low propensity to undergo regular dental examinations. The percentage of subjects with pathologies of the oral cavity was 18.6%. Conclusions: Despite the smallness of the sample, this pilot project could facilitate the acquisition of valid and cost-effective data for the primary prevention of oral cancer through information and educational campaigns on the related risk factors

    Some compounds, characterized by phenylethenyl moiety, such as methyl cinnamate and caffeic acid phenethyl ester, are able to inhibit C. albicans biofilm formation. On these bases, and as a consequence of our previous work, we synthesized a series of cinnamoyl ester and amide derivatives in order to evaluate them for the activity against C. albicans biofilm and planktonically grown cells. The most active compounds 7 and 8 showed ⩾50% biofilm inhibition concentrations (BMIC50) of 2 μg/mL and 4 μg/mL respectively, against C. albicans biofilm formation; otherwise, 7 showed an interesting activity also against mature biofilm, with BMIC50 of 8 μg/m

    PERSISTENCE BY DIVISION: A STUDY OF HIV-1 RESERVOIR QUANTIFICATION AND ITS MAINTENANCE THROUGH ANTIGEN-DRIVEN T CELL PROLIFERATION

    Antiretroviral therapy (ART) greatly reduces HIV-1 morbidity and mortality. However, it has no effect on the HIV-1 reservoir, a small pool of latently infected cells that rekindles infection upon treatment interruption. Due to the persistence of this reservoir, ART must be continued indefinitely, requiring public health systems to deliver medications to all 38 million people living with HIV-1 for life. In this dissertation we explore two outstanding challenges of our field: i) understanding the composition and magnitude of persistent HIV-1-infected cells, and ii) identifying the mechanisms that allow the maintenance of the reservoir through cell proliferation. The assays currently used to measure HIV-1 persistence present limitations. Culture-based approaches, considered the gold-standard in determining the size of the reservoir with inducible, replication competent proviruses, allow recovery of infectious virus. However, outgrowth assays are labor-intensive, require large numbers of cells, and rely on proviral reactivation from latency, which can lead to an underestimation of reservoir size. On the other hand, PCR-based assays can be easily implemented in most laboratories, but fail to distinguish intact from defective proviruses, the latter representing about 90% of the proviral landscape. Our group recently developed the Intact Proviral DNA Assay (IPDA), a method based on a duplexed droplet digital PCR that offers a paradigm shift in the quantification of HIV-1 DNA. The IPDA provides rapid and sensitive detection of HIV-1 DNA with two strategically designed sets of primers and probes that allow the parsing of intact proviruses from those with lethal mutations. In this dissertation, we demonstrate the scalability of this approach, studying a cohort of 400 individuals living with HIV-1 on ART. The reservoir is maintained by the long half-life and proliferation of infected cells. Through proliferation, cells infected before the introduction of ART give rise to clonal progeny harboring identical copies of HIV-1 DNA integrated into the cell genome. Despite its central role, the mechanisms of this persistence through division are not completely understood. Thus, if the cells that we aim to eliminate proliferate in infected individuals, we need to understand why and find a way to stop this phenomenon. There are three potential causes driving the expansion of infected cells: homeostatic proliferation, insertional mutagenesis due to HIV-1 integration in specific genes, and the interaction with cognate or cross-reacting antigens. In this dissertation, we investigated the role of chronic viral antigens, such as those from cytomegalovirus, in driving the expansion of HIV-1-infected clones in vivo. We demonstrated that antigen-driven clonal selection leads to large, infected clones that persist over time. Overall, the results from this thesis work suggest that antigen-driven clonal expansion, relative to homeostatic proliferation and HIV-1 integration, plays a major role in promoting HIV-1 persistence and that adaptive immune responses impose selective pressure on HIV-1-infected cells

    La desestatización de la función jurisdiccional en los procesos concursales de las entidades de intermediación financiera y de valores.

    Abstract. This paper deals with the changes introduced by Laws 18.401 and 18.627, which entrusted the bankruptcy proceedings of banks, stock exchanges and other related persons, to non-governmental entities. This is a violation of the Constitution, which specifies who are the subjects that may develop the Jurisdictional role, establishing it asan exclusive performance by the State, mainly by the Judiciary. These unconstitutional legislative innovations affect the procedural rights of debtors and creditors in bankruptcy, to the point of compromising the existence of the Due Process, which cannot be assured out of the State courts designated by the Constitution.Resumen. El presente trabajo trata sobre los cambios introducidos por las leyes 18401 y 18627, que confiaron los procesos concursales de bancos, bolsas de valores y otras personas afines a personas jurídicas que no integran el Estado. Esto supone una violación a la Constitución, que indica taxativamente qué sujetos pueden desarrollar la función jurisdiccional, y la establecen como un cometido exclusivo del Estado, a cargo, en principio, del Poder Judicial. Estas innovaciones legislativas inconstitucionales afectan los derechos procesales de deudores y acreedores concursales, al extremo de ver comprometida la existencia misma del debido proceso, el que no puede asegurarse fuera de los tribunales estatales designados por la Constitución

    Get PDF
    Essa dissertação tem como objetivo compreender o imaginário amazônico na poética visual do artista autodidata Eli Bacelar, que nasceu em Manaus - Amazonas em 1960 e aos 15 anos participou da primeira exposição. Ao longo de sua trajetória de 45 anos recebeu premiações e participou de diversas exposições regionais e nacionais. Desta forma, a escolha do artista se justifica por sua importância para a história da arte local e pela carência de informações, pois quando se busca, sobre sua produção, não se encontra muitas referências. Em relação a abordagem metodológica, quanto a natureza a pesquisa foi qualitativa e quantos aos meios foi bibliográfica e documental que foram utilizados como suporte na produção do referencial teórico. Quanto a análise dos documentos de processo como rascunhos e esboços, recorreuse à abordagem utilizada pela Crítica Genética. Na pesquisa de campo, foram realizadas diversas entrevistas com o artista e visitas os acervos públicos e colecionadores particulares. Como resultado, além de apresentar uma abordagem sobre os aspectos pertinente aos caminhos da sua vida pessoal e artística e o registro de 160 trabalhos entre pinturas, desenhos e esboços, a pesquisa debruçou-se na análise do processo criativo e poético de algumas obras à luz imaginário amazônico. Desta forma foi possível perceber o caminho percorrido na elaboração e amadurecimento de seu estilo e observar as relações construídas pelo artista, e os diversos aspectos da cultura amazônica e universal.This dissertation aims to understand the Amazonian imaginary in the visual poetics of the selftaught artist Eli Bacelar, who was born in Manaus - Amazonas in 1960 and at the age of 15 participated in the first exhibition. Throughout his 45-year history he has received awards and participated in several regional and national exhibitions. Of this firm, the choice of the artist is justified by its importance for the history of local art and the lack of information, because when searching, about its production, there are not many references. Regarding the methodological approach, how much the research was qualitative and how many to the means was bibliographic and documentary that were used as support in the production of the theoretical framework. After the analysis of process documents such as drafts and drafts, the approach used by Genetic Criticism was used. In the field research, several interviews were conducted with the artist and visits the public collections and private collectors. As a result, in addition to presenting an approach on the aspects pertinent to the paths of his personal and artistic life and the recording of 160 works among paintings, drawings and sketches, the research focused on the analysis of the creative and poetic process of some works in the Amazonian imaginary light. In this way it was possible to perceive the path taken in the elaboration and maturation of his style and observe the relationships constructed by the artist, and the various aspects of Amazonian and universal culture
