1. Sobre Anéis de Lie Admitindo Automorfismos de Ordens Finitas e Álgebras de Lie Quase Nilpotentes. / Sobre Anéis de Lie Admitindo Automorfismos de Ordens Finitas e Álgebras de Lie Quase Nilpotentes. / On lie Rings Admitting Automorphisms of Fintite Order and Lie Algebras Almost Nilpotent / On lie Rings Admitting Automorphisms of Fintite Order and Lie Algebras Almost Nilpotent
Nesta dissertação apresentamos um estudo sobre anéis e álgebras de Lie admitindo um automorfismo de ordem finita, com ênfase em questões sobre nilpotência. Demonstramos resultados importantes desta teoria, como por exemplo o Teorema de Higman, Kreknin e Kostrikin. Além disso, considere L uma álgebra de Lie de dimensão finita sobre um corpo algebric

2. Algebras de Lie finitamente apresentaveis
Nesta dissertação de mestrado, estudamos propriedades de álgebras de Lie. As Álgebras de Lie têm grande importância nao somente na teoria de álgebras não associativas, elas surgem também em geometria, topologia e no estudo da teoria de grupos por exemplo. As definições e resultados básicos sobre álgebras de Lie estão inclusos no Capítulo 2. Pa

3. The Rolling Circle for ϕX DNA Replication, II. Synthesis of Single-Stranded Circles*
ϕX-infected cells have been allowed to incorporate tritiated thymidine late in the phage life cycle when single-stranded circles are the product of DNA synthesis. Virtually all of the radioactivity is recovered in a continuum of actively replicating viral DNA molecules. These molecules are termed rolling circle intermediates because they are characterized b

4. Metastatic breast carcinoma with appearance resembling micropapillary ductal carcinoma in situ.
AIM--To investigate tumour in an axillary lymph node resembling micropapillary ductal carcinoma in situ. METHODS--Sections of tumour in the breast and axillary lymph node were stained with haematoxylin and eosin, and immunohistochemically with antibodies to basement membrane and myoepithelial cells. RESULTS--Tumour in both the breast and axillary lymph node

5. The crystal structure of the complex between a disaccharide anthracycline and the DNA hexamer d(CGATCG) reveals two different binding sites involving two DNA duplexes
The crystal structure of the complex formed between the anthracycline antibiotic 3′-deamino-3′- hydroxy-4′-(O-l-daunosaminyl)-4-demethoxydoxo rubicin (MEN 10755), an active disaccharide analogue of doxorubicin, and the DNA hexamer d(CGATCG) has been solved to a resolution of 2.1 Å. MEN 10755 exhibits a broad spectrum of antitumor activities, comparab

6. Cell envelope associations of Aquaspirillum serpens flagella.
Specific regions of the cell envelope associated with the flagellar basal complex of the gram-negative bacterium Aquaspirillum (Spirillum) serpens were identified by studying each of the envelope layers: outer membrane, mucopeptide, and plasma membrane. The outer membrane around the flagella insertion site was differentiated by concentric membrane rings and

7. On the biologically active structures of cholecystokinin, little gastrin, and enkephalin in the gastrointestinal system.
The biologically active conformations of a series of four peptides [four cholecystokinin (CCK)-related peptides and enkephalin] in their interactions with gastrointestinal receptors have been deduced using conformational computational analysis. The two peptides that interact exclusively with peripheral-type CCK receptors are the heptapeptide COOH-terminal fr
