Características clínicas laboratoriais de 104 casos de meningoencefalite criptocócica

Com o objetivo de descrever as características clínicas e laboratoriais da meningoencefalite criptocócica, foram analisados 104 prontuários de pacientes com este diagnóstico, internados no Hospital Couto Maia, na cidade de Salvador-Bahia, no período de 1972 a 1996. A idade dos pacientes variou de 8 meses a 79 anos. Sessenta e quatro (61,5%) enfermos eram do sexo masculino. O tempo de doença variou de 2 a 150 dias, com média de 27,6 dias. Os sinais e sintomas clínicos mais comuns foram cefaléia (92,7%), febre (84,4%) e rigidez de nuca (83,2%). A celularidade do líquido cefalorraquiano foi superior a 4 cels/mm+ em 95,8% dos pacientes com predominância de linfócitos em 86,3% dos casos. A letalidade foi de 42,7%.

Effects of PDE type 5 inhibitors on Left Ventricular Diastolic Dysfunction in Resistant Hypertension

Resistant hypertension (RHTN) is a multifactorial disease characterized by blood pressure (BP) levels above goal (140/90 mmHg) in spite of the concurrent use of three or more antihypertensive drugs of different classes. Moreover, it is well known that RHTN subjects have high prevalence of left ventricular diastolic dysfunction (LVDD), which leads to increased risk of heart failure progression. This review gathers data from studies evaluating the effects of phosphodiesterase-5 (PDE-5) inhibitors (administration of acute sildenafil and short-term tadalafil) on diastolic function, biochemical and hemodynamic parameters in patients with RHTN. Acute study with sildenafil treatment found that inhibition of PDE-5 improved hemodynamic parameters and diastolic relaxation. In addition, short-term study with the use of tadalafil demonstrated improvement of LVDD, cGMP and BNP-32 levels, regardless of BP reduction. No endothelial function changes were observed in the studies. The findings of acute and short-term studies revealed potential therapeutic effects of IPDE-5 drugs on LVDD in RHTN patients.

Tracing lineage by phenotypic and genotypic markers in Salmonella enterica subsp. enterica serovar 1,4,[5],12:i:- and Salmonella Typhimurium isolated in state of São Paulo, Brazil

Fifty-three Salmonella 1,4,[5],12:i:- and 45 Salmonella Typhimurium strains were characterised using phage typing, plasmid profiles and pulsed-field gel electrophoresis (PFGE) for comparison. The majority of the strains were subdivided into definitive type (DT) 41 (22.6%) and DT 193 (18%) and the 60-MDa plasmid was detected in 94.3% and 84.4% of strains, respectively. Genetic diversity was observed among all strains and 90% presented a > 70% similarity through PFGE analysis. These results suggest a close relationship between Salmonella 1,4,[5],12:i:- and Salmonella Typhimurium at the serotype level.

Eduardo Neves, nosso eterno mestre

Eduardo Fausto de Almeida Neves, Professor Emeritus of the Universidade Federal de São Carlos and formerly Full Professor at the Instituto de Química - Universidade de São Paulo (USP), São Paulo, Brazil, was born in November 7, 1933 in Pedra Azul, MG, and deceased in July 2, 2006 in São Carlos, SP. He graduated under supervision of Professor Paschoal Senise, pioneer of Analytical Chemistry at USP, and developed his post-doctoral work at Caltech, USA, with Professor Fred Anson. His brilliant career as teacher, scientist, supervisor and mentor resulted in a prolific science school in Analytical Chemistry, with some sixty PhDs and masters supervised by him, amplified to over four hundred in the 2nd to 4th generations (still growing), spread throughout the country and nucleating new research groups. The contents of a hundred papers reflect Prof. Eduardo's wide range of scientific interests. Passionate inclination for creative intellectual activity, rooted in profound knowledge of all branches of Chemistry, broadminded thinking, sound experimentation, generous scientific cooperation and true friendship - that's why friends, colleagues and students referred to him as "master" or "my guru".

Sequence analysis of the 5′ third of glycoprotein C gene of South American bovine herpesviruses 1 and 5

Bovine herpesviruses 1 (BoHV-1) and 5 (BoHV-5) share high genetic and antigenic similarities, but exhibit marked differences in tissue tropism and neurovirulence. The amino-terminal region of glycoprotein C (gC), which is markedly different in each of the viruses, is involved in virus binding to cellular receptors and in interactions with the immune system. This study investigated the genetic and antigenic differences of the 5′ region of the gC (5′ gC) gene (amino-terminal) of South American BoHV-1 (n=19) and BoHV-5 (n=25) isolates. Sequence alignments of 374 nucleotides (104 amino acids) revealed mean similarity levels of 97.3 and 94.2% among BoHV-1 gC (gC1), respectively, 96.8 and 95.6% among BoHV-5 gC (gC5), and 62 and 53.3% between gC1 and gC5. Differences included the absence of 40 amino acid residues (27 encompassing predicted linear epitopes) scattered throughout 5′ gC1 compared to 5′ gC5. Virus neutralizing assays testing BoHV-1 and BoHV-5 antisera against each isolate revealed a high degree of cross-neutralization between the viruses, yet some isolates were neutralized at very low titers by heterologous sera, and a few BoHV-5 isolates reacted weakly with either sera. The virus neutralization differences observed within the same viral species, and more pronounced between BoHV-1 and BoHV-5, likely reflect sequence differences in neutralizing epitopes. These results demonstrate that the 5′ gC region is well conserved within each viral species but is divergent between BoHV-1 and BoHV-5, likely contributing to their biological and antigenic differences.

Redox reactions of group 5 elements, including element 105, in aqueous solutions

Standard redox potentials E^0(M^z+x/M^z+) in acidic solutions for group 5 elements including element 105 (Ha) and the actinide, Pa, have been estimated on the basis of the ionization potentials calculated via the multiconfiguration Dirac-Fock method. Stability of the pentavalent state was shown to increase along the group from V to Ha, while that of the tetra- and trivalent states decreases in this direction. Our estimates have shown no extra stability of the trivalent state of hahnium. Element 105 should form mixed-valence complexes by analogy with Nb due to the similar values of their potentials E^0(M^3+/M^2+). The stability of the maximumoxidation state of the elements decreases in the direction 103 > 104 > 105.
