Introdução: É indispensável ter um conhecimento profundo da morfologia da glândula tiróide e das estruturas com ela relacionadas no compartimento anterior do pescoço, para minimizar a morbilidade decorrente da cirurgia da tiróide, nomeadamente a lesão das glândulas paratiróides e dos nervos laríngeos. Este estudo pretendeu identificar glândulas paratiróides em peças de cadáver, confirmando-as histologicamente.M...
Introduction: The extensor tendons of fingers are subject of many variations, some of them quite frequent.Material and Methods: The dissection of the posterior region of forearm and hand was carried out, and the anatomical variations were documented.Results: In Case 1 the extensor digitorum divided into 5 tendons: one for the index finger, one for the middle finger, two for the ring finger and one for the littl...
Introduction: There are several reports of sciatic nerve anatomical variations. Some are associated with clinical entities, such as piriformis syndrome. We aim to report a rare anatomical variation of this nerve.Cases report: Two leucodermic, 74 and 78-year-old male subjects, deceased of natural causes, without lower limb relevant medical history. In both subjects, the right sciatic nerve was absent, with an in...
A high solubility of antituberculosis antibiotic drugs: isoniazid and pyrazinecarboxamide in ammonium ionic liquids shown in this work, demonstrates the promising perspectives in the drug processing. Solid–liquid equilibrium (SLE) measurements have been made using a dynamic (synthetic) method. Thermophyscial properties such as melting point, enthalpy of fusion, temperatures of phase transitions and correspondi...
The solubility of N-acetyl-l-cysteine, coumarin and 4-hydroxycoumarin in alternative solvents was studied in this work. The solid–liquid equilibrium (SLE) measurements have been performed using a dynamic(synthetic) method. Melting points and enthalpies of fusion of the pharmaceutical compounds were acquired using a differential scanning calorimetry (DSC). The solubility of N-acetyl-l-cysteine and 4-hydroxycoum...
The sufficient solubility of isoniazid in alternative solvents obtained in this work can open new perspectives in pharmaceutical processing. Solid–liquid equilibrium (SLE) measurements have been made using a dynamic (synthetic) method. The melting point and the enthalpy of fusion of isoniazid were acquired using differential scanning calorimetry (DSC). The solubility of isoniazid in bis(trifluoromethylsulfonyl)...
Exploitation of neoteric solvents in the efficient total synthesis of carvacrol, an antimicrobial reagent, has been accomplished. The first reaction aimed supercritical mediated heterogeneous hydrogenation of carvone catalysed by palladium. The second step guided to an application of great salvation capacity of ionic liquids in separation of carvacrol from the post-hydrogenation mixture. The process has been co...
Dissertação para obtenção do Grau de Mestre em Engenharia Química e Bioquimica ; Hydrogenation of monoterpenes, such as carvone, in high-density carbon dioxide over 0.5 wt.% Pd, or Rh, or Ru supported on alumina was investigated. Hydrogenation is generally faster in a single supercritical (sc) phase than in a biphasic system. The reaction catalysed by Pd produces full hydrogenated products (isomers of carvomen...
