Mineiro do Brasil :melhorado pelo conhecimento da mineralogia, e metalurgia, e das sciencias auxiliadoras /por Mr. de Genssane ; traduzido em portuguez (SIC) de ordem de Sua Alteza Real, o Principe Regente N.S. por Fr. José Mariano da Conceição Velloso

Esse livro é parte do gigantesco esforço de Frei Velloso para oferecer aos brasileiros os melhores livros relacionados com a agricultura, a mineração, a pecuária e as artes que se podiam obter àquela época. Como relata Borba de Moraes, o esforço fracassou devido ao imenso atraso das elites brasileiras da época. A respeito do Fazendeiro do Brasil, o Governador de São Paulo informou à Corte que não conseguira vender um só exemplar da coleção e que não achava quem os quisesse levar de graça.Ressalte-se que esse exemplar não possui as sete gravuras mencionadas por Borba de Moraes.

Hyperpolarized Xe MR imaging of alveolar gas uptake in humans.

BACKGROUND: One of the central physiological functions of the lungs is to transfer inhaled gases from the alveoli to pulmonary capillary blood. However, current measures of alveolar gas uptake provide only global information and thus lack the sensitivity and specificity needed to account for regional variations in gas exchange. METHODS AND PRINCIPAL FINDINGS: Here we exploit the solubility, high magnetic resonance (MR) signal intensity, and large chemical shift of hyperpolarized (HP) (129)Xe to probe the regional uptake of alveolar gases by directly imaging HP (129)Xe dissolved in the gas exchange tissues and pulmonary capillary blood of human subjects. The resulting single breath-hold, three-dimensional MR images are optimized using millisecond repetition times and high flip angle radio-frequency pulses, because the dissolved HP (129)Xe magnetization is rapidly replenished by diffusive exchange with alveolar (129)Xe. The dissolved HP (129)Xe MR images display significant, directional heterogeneity, with increased signal intensity observed from the gravity-dependent portions of the lungs. CONCLUSIONS: The features observed in dissolved-phase (129)Xe MR images are consistent with gravity-dependent lung deformation, which produces increased ventilation, reduced alveolar size (i.e., higher surface-to-volume ratios), higher tissue densities, and increased perfusion in the dependent portions of the lungs. Thus, these results suggest that dissolved HP (129)Xe imaging reports on pulmonary function at a fundamental level.

Assessing the image quality of pelvic MR images acquired with a flat couch for radiotherapy treatment planning

Objectives: To improve the integration of MRI with radiotherapy treatment planning, our department fabricated a flat couch top for our MR scanner. Setting up using this couch top meant that the patients were physically higher up in the scanner and, posteriorly, a gap was introduced between the patient and radiofrequency coil.
