1. Medidas de secções de choque de fusão dos sistemas 16o + 46,50ti / Measures sections of shock melting systems 16th ti + 46.50
Foram medidas funções de excitação para a fusão completa dos sistemas 16O+46,50Ti em energias abaixo e em torno da barreira Coulombiana. A seção de choque de fusão foi obtida utilizando-se os métodos da espectroscopia em linha e fora da linha através da soma das seções de choque dos canais de decaimento do núcleo composto formado, observados exp

2. Intracellular fate of Mycobacterium avium: use of dual-label spectrofluorometry to investigate the influence of bacterial viability and opsonization on phagosomal pH and phagosome-lysosome interaction.
Mycobacterium avium is a facultative intracellular pathogen that can survive and replicate within macrophages. We tested the hypotheses that survival mechanisms may include alteration of phagosomal pH or inhibition of phagosome-lysosome fusion. M. avium was surface labeled with N-hydroxysuccinimidyl esters of carboxyfluorescein (CF) and rhodamine (Rho) to en

3. Structural heterogeneity of the Fe(2+)-N epsilon (HisF8) bond in various hemoglobin and myoglobin derivatives probed by the Raman-active iron histidine stretching mode.
We have examined the Fe(2+)-N epsilon (HisF8) complex in hemoglobin A (HbA) by measuring the band profile of its Raman-active nu Fe-His stretching mode at pH 6.4, 7.0, and 8.0 using the 441-nm line of a HeCd laser. A line shape analysis revealed that the band can be decomposed into five different sublines at omega 1 = 195 cm-1, omega 2 = 203 cm-1, omega 3 =
