1. Could Cerebrospinal Fluid Biomarkers Offer Better Predictive Value for Spinal Cord Ischaemia Than Current Neuromonitoring Techniques During Thoracoabdominal Aortic Aneurysm Repair - A Systematic Review
Abstract Objective: Cerebrospinal fluid (CSF) drainage is a technique that has significantly reduced the incidence of spinal cord ischaemia (SCI). We present results of a systematic review to assess the literature on this topic in relation to thoracoabdominal aortic aneurysm repair (TAAR). Methods: Major medical databases were searched to identify papers r

2. Estudo qualitativo e quantitativo de biomarcadores ácidos e hidrocarbonetos presentes em óleos da Bacia Potiguar / Qualitative and quantitative study of acidic and hydrocarbon biomarkers of oil from the Potiguar Basin
rabalho foram sintetizados quatro biomarcadores ácidos, a saber: ácido 5b (H) colânico (2), 5a (H) homopregnânico (4), 8,13-tetraidrocopálico (6) e 15-isocopálico (7). Para tanto, foram utilizadas matérias primas comerciais (ácido litocólico e estigmasterol) e o ácido copálico (extraído e purificado a partir de bálsamo de copaíba). Também foi

3. Influência do alumínio e do pH ácido sobre a fisiologia reprodutiva de peixes teleósteos continentais / Influence of aluminium and acidic pH over the reproductive physiology of freshwater teleost fish
A reprodução em peixes é controlada pelo eixo hipotálamo-hipófise-gônadas e os fatores que alteram o funcionamento adequado deste eixo são chamados de disruptores endócrinos. Muitos metais têm o papel de disruptores endócrinos e dentre eles destaca-se o alumínio que, além de afetar o sistema endócrino de algumas espécies de peixes, pode alterar

4. Synthesis and identification of biomarkers in oils of the Campos and Potiguar Basin: identification of 3-alkyl-steranes / Sintese e identificação de biomarcadores em oleos da Bacia de Campos e Bacia Potiguar : identificação de 3-alquil-esteranos
This work reports an investigation using oils from Campos (southem Brazil) and Potiguar (northeastem Brazil) Basins which are the two most important petroleum producer basins in the country. The main focus in this research was the analysís of neutral and acidic biomarkers as indicators of biodegradation. Consequently, we have selected oils samples originate

5. Estudo geoquimico de oleos do Campo de Marlim, Bacia de Campos, sintese de biomarcadores esteranos aromaticos
This thesis presents the geochemical study of three oil samples: PCM1, PCM2 e PCM3, all pertaining to the Marlin Field located in the Campos Basin, Rio de Janeiro and were generated by saline lacustrine source rocks. The crude oils were studied by the gas chromatography coupled whith mass spectrometry (GC/MS technique), and standards were used in this resear

6. Biomarcadores acidos da bacia Sergipe-Alagoas e estudos sinteticos de esteranos monoaromaticos
This research work has ultimate objective of addressing three issues. The first issue envolves the investigation of acidic biomarkers present in 10 oil samples of Carmopolis oil Field of Sergipe-Alagoas Basin, which have a marine-evaporitic origin. The main classes of carboxylic acids biomarkers which were characterized as their methyl ester or their deuteri

7. Detalhes da historia geologica de Campo de Albacora - Bacia de Campos a partir de biomarcadores acidos
The GC/MS biomarker analyses of eight oils from Albacora Field - Campos Basin(RJ), revealed that the acidic fossil molecules are sensitive to geological phenomena connected with the formations of the reservoirs. It was sugggested some years ago that the reservoirs in Albacora Field were mixtures of two oil pulses of different thermal evolution. This hypothes
