Inorganic profile of some Brazilian medicinal plants obtained from ethanolic extract and ''in natura'' samples  

Energy Technology Data Exchange (ETDEWEB)

The Anadenathera macrocarpa, Schinus molle, Hymenaea courbaril, Cariniana legalis, Solidago microglossa and Stryphnodendron barbatiman, were collected ''in natura'' samples (leaves, flowers, barks and seeds) from different commercial suppliers. The pharmaco-active compounds in ethanolic extracts had been made by the Mato Grosso Federal University (UFMT). The energy-dispersive x-ray fluorescence (ED-XRF) spectrometry was used for the elemental analysis in different parts of the plants and respective ethanolic extracts. The Ca, Cl, Cu, Fe, K, Mg, Mn, Na, Ni, P, Rb, S, Sr and Zn concentrations were determined by the fundamental parameters method. Some specimens showed a similar inorganic profile for ''in natura'' and ethanolic extract samples and some ones showed a distinct inorganic profile. For example, the Anadenathera macrocarpa showed a similar concentration in Mg, P, Cu, ...

Microwaves as low frequency radiation in degradations of pollutants; Le microonde come attivatori della degradazione di inquinanti  

Energy Technology Data Exchange (ETDEWEB)

The proposed aim of the work is to verify the effects produced on different kinds of environmental pollutants after exposure to a low frequency radiation such as microwaves. They have proved capable of producing minimum heating of the matrix as well as modifications in the structure of the molecules at the level of simple bonds. Steps were also taken ti check whether the degradation action of the microwaves could be boosted by sunlight. For this reason tests were run also on samples irradiated using microwaves and a lamp capable of simulating the sun's spectrum, as well as in the presence of a single lamp. [Italian] Lo scopo di questa ricerca e' di verificare gli effetti prodotti su inquinanti ambientali, di diversa natura, a seguito di un'esposizione ad una radiazione a bassa frequenza come le microonde. Le microonde possono produrre minimi riscladamenti della matrice e modificazioni della struttura delle molecole, a livello di legami ...

The law aspects of biotechnology patenting. The living source between discovery and invention; Aspetti giuridici del brevetto biotecnologico. La materia vivente tra scoperta e invenzione  

Energy Technology Data Exchange (ETDEWEB)

The aim of this work is to provide a comprehensive and consistent description of the complexity of laws regulating the field of biotechnology, mainly focusing on the definition of items to be patented, which is one of the most important and also controversial issues within the new 98/44/EC set of rules. As biotechnology is a specialist and multidisciplinary field, it has begun by giving a general description of the field, outlining the grounds for the new rules, and then thoroughly examined and evaluated previous national and international laws especially with regard to patenting. This was followed by an evaluation of what can be patented according to the new instructions by systematically assessing the section defining items to be patented in the field of biotechnology. It is used to be a matter of opinion whether biotechnological material was to be considered a discovery or an invention, the former being impatentable according to patenting laws. The new law pays particular attention ...

CT in the study of thoracic-pulmonary complications after liver transplantation; La Tomografia Computerizzata nello studio delle complicanze toraco-polmonari dopo trapianto del fegato  

Energy Technology Data Exchange (ETDEWEB)

In this article is reviewed the role of Computed Tomography (CT) in thoracic complications following ortho topic liver transplantation (OLT). In a post-OLT population of 567 patients transplanted in the Italian institutions, 100 patients (17.6%) were examined with chest CT. It was reviewed data relative to the total number of examinations, clinical and/or radiographic indications, the CT technique-i.e., conventional (with (out) intravenous, i.v., contrast material) or high-resolution (HRCT). It also reviewed the radiologic patterns and their correlation with the other clinical, bronchoscopic and/or laboratory results. Of 152 chest CT examinations, 45 (29.6%) were performed because of clinical indications, 31 (20.4%) because of a radiographic abnormality, 64 (42.1%) because of clinical and radiographic abnormality, 64 (42.1%) because of clinical and radiographic indications, while in 12 cases (7.9%) the reasons were unknown; 133/152 (87.5%) examinations had been performed with ...
