Abstract:

A esquizofrenia é um transtorno psiquiátrico grave, caracterizado por distúrbios do pensamento, prejuízo da lógica, alterações cognitivas e emocionais, e/ou isolamento social. Apesar da introdução de novos antipsicóticos, um grupo considerável de pacientes ainda é refratário aos tratamentos disponíveis. Além disso, a alta incidência de efeitos adversos leva à baixa adesão ao tratamento em esquizofrênicos. O desenvolvimento de tratamentos mais eficazes e com menor incidência de efeitos adversos, que aumentem a adesão ao tratamento e melhorem a qualidade de vida destes pacientes, é assim altamen

Abstract:

Despite being preventable and treatable, malaria continues to be a significant threat to global health, particularly in the developing world. It is estimated that 90% of all malaria deaths occur in Africa and that 78% of these deaths occur in children under five years of age due to infection with Plasmodium falciparum malaria parasites. While malaria control strategies, together with the global malaria eradication agenda, has resulted in a 48% decline in global malaria mortality rates over the past decade, progress has stalled. A recent rise in malaria cases is particularly concerning given th

Abstract:

Ainda que descrita pela primeira vez em 1893 por Emil Kraepelin, a esquizofrenia continua sendo uma doença mental extremamente debilitante e de difícil tratamento. A introdução dos antipsicóticos típicos na década de 50 e dos atípicos na década de 90 mudou consideravelmente a realidade dos esquizofrênicos, no entanto a baixa eficácia (principalmente quanto aos sintomas negativos e cognitivos) associada a alta incidência de efeitos adversos requer inovação na farmacodinâmica de antipsicóticos.

Abstract:

This thesis examines the total synthesis of the macroline-related indole alkaloid alstonerine and related compounds. It is divided into three sections: The first section provides a review of the total synthesis efforts reported by Cook, Martin, Kuethe, and Kwon, as well previous work within the Craig group. The second section discusses the results of our investigations. The optimisation of the synthesis of key intermediate α,β-unsaturated lactam alcohol via directed-aziridine ring-opening is presented in detail.

Analogy arguments from religious experience attempt to establish a direct analogy between sense perception and certain kinds of religious experience construed in terms of a perceptual model. C. B. Martin challenges traditional analogy arguments from religious experience by contending that there is a disanalogy between both kinds of experience due to the fact that there is a society of testing and checkup procedures available to sense perception that is not available to religious experience.
