1. DEPLOYMENT OF METHOD FOR ANALYSIS OF STABLE CARBON ISOTOPES (N-ALKANES C1-C5) IN GAS SAMPLES AT LOW CONCENTRATIONS / IMPLANTAÇÃO DE MÉTODO PARA ANÁLISE DE ISÓTOPOS ESTÁVEIS DE CARBONO (N-ALCANOS C1-C5) EM GASES A BAIXAS CONCENTRAÇÕES
The concentration and isotopic composition of n-alkanes C1-C5 has revealed as a powerful tool for interpretation of interesting processes in the oil exploration industry, studies of global climate change, oil biodegradation and carbon cycle elucidation. In this context, studies about methane analysis have been distinguished and multiplied due to the importan

2. Hyptis fruticosa Salzm. ex Benth. (Lamiaceae): caracterização botânica, química, avaliações ecofisiológicas e atividades farmacológicas. / Hyptis fruticosa Salzm. ex Benth. (Lamiaceae): characterization botany, chemistry, ecophysiological assessments and pharmacological activities.
Hyptis fruticosa Salzm. ex Benth. (Alecrim do campo) is an aromatic plant widely used in folk medicine due to its therapeutic properties. Therefore the aim of this work was to undertake botanical, chemical, ecophysiological, and pharmacological studies. The botanical investigations observed and analyzed information about morphological, physiological, and env

3. Desenvolvimento e validação de metodologia analítica para a determinação de canabidiol e tetraidrocanabinol em amostras de plasma por cromatografia em fase gasosa/espectrometria de massas / Development and validation of an analytical methodology for determination of cannabidiol and tetrahydrocanabinol in plasma samples using gas phase chromatografy /mass espectrometry
Dissertation (Master). Faculdade de Ciências Farmacêuticas de Ribeirão Preto Universidade de São Paulo, Ribeirão Preto, 2008. The Cannabidiol (CBD), that represents about 40% of the cannabinoids found in Cannabis sativa plant, is devoided of the typical psychological and cognitive effects of 9-Tetrahydrocannabinol (9THC). Researches suggest that CBD sho

4. Expressão de uricase de Bacillus subtilis em escherichia coli
Bacillus subtilis URICASE EXPRESSION IN Escherichia coli Uricase, an enzyme that converts uric acid into allantoin, is commonly used in commercial kits for uric acid detection. Aiming to produce this enzyme in industrial scale using Genetic Engineering techniques, the uricase gene of Bacillus subtilis subtilis was cloned and expressed in Escherichia coli. In

5. DetecÃÃo de variantes somaclonais de bananeira âPrata AnÃâ (AAB) micropropagada / Detection of somaclonal variants of micropropagated banana plants âPrata Anaâ (AAB)
The in vitro culture, also known as micropropagation, is a technique used in the attainment of plants with commercial value. This technique is useful in achievement for free pathogenic plants and to maintain the genetic characteristics of the mother plant. However, the micropropagation can lead to phenotypic changes in the plants, known as somaclonal variati

6. Emissão de 14C pelas unidades I e II da Central Nuclear Almirante Álvaro Alberto (CNAAA) e seu efeito local nos níveis ambientais
14 C is a is a long-lived beta-emitting nuclide (T = 5730 years) produced naturally 1/2 14 14 14 in the upper atmosphere as a result of reactions between neutrons and stable N( N(n,p) C). 14 C as well during their routine Although in a lesser extent, nuclear power plants produce 14 operation. Since it is converted in CO and mixed throughout the atmosphere, i

8. Identificação e caracterização de proteinas que se associam in vitro a fita telomerica rica em G de Leishmania (Leishmania) amazonensis / Identification and characterization of proteins that associate in vitro with the Leishmania (Leishmania) amazonensis G-rich telomeric strand
The chromosomal ends of Leishmania (Leishmania) amazonensis contain conserved 5 - TTAGGG-3 telomeric repeats, that are maintained by telomerase. Using Telomeric Repeat Amplification Protocol (TRAP) we detected telomerase activity in protein fractions purified from S100 and nuclear extracts. Protein complexes that associate in vitro with telomeric DNA sequenc

9. Compostos volateis de meis de eucalipto e laranja
Volatile compounds of orange and eucalyptus honey from São Paulo and Minas Gerais were isolated by a Dinamic Headspace methodology on porapak Q, and separated by high resolution gas chromatography. The best solvent and the best time for concentration of the volatile compounds on Porapak Q were determined by analysing both the obtained chromatogram, and the
