Night-time tropospheric chemistry of the unsaturated alcohols (Z)-pent-2-en-1-ol and pent-1-en-3-ol: Kinetic studies of reactions of NO3 and N2O5 with stress-induced plant emissions

The night-time tropospheric chemistry of two stress-induced volatile organic compounds (VOCs), (Z)-pent-2-en-1-ol and pent-1-en-3-ol, has been studied at room temperature. Rate coefficients for reactions of the nitrate radical (NO3) with these pentenols were measured using the discharge-flow technique. Because of the relatively low volatility of these compounds, we employed off-axis continuous-wave cavity-enhanced absorption spectroscopy for detection of NO3 in order to be able to work in pseudo first-order conditions with the pentenols in large excess over NO3. The rate coefficients were determined to be (1.53 +/- 0.23) x 10(-13) and (1.39 +/- 0.19) x 10(-14) cm(3) molecule(-1) s(-1) for reactions of NO3 with (Z)-pent-2-en-1-ol and pent-1-en-3-ol. An attempt to study the kinetics of these reactions with a relative-rate technique, using N2O5 as source of NO3 resulted in significantly higher apparent rate coefficients. Performing relative-rate experiments in known excesses of NO2 allowed us to determine the rate coefficients for the N2O5 reactions to be (5.0 +/- 2.8) x 10(-19) cm(3) molecule(-1) s(-1) for (Z)-pent-2-en-1-ol, and (9.1 +/- 5.8) x 10(-19) cm(3) molecule(-1) s(-1) for pent-1-en-3-ol. We show that these relatively slow reactions can indeed interfere with rate determinations in conventional relative-rate experiments.

Prevalência dos Vírus linfotrópico de células T humanas 1 e 2 (HTLV-1 e HTLV-2), Herpesvírus humano 5 (Citomegalovírus) e Vírus da hepatite B (VHB) em mulheres grávidas portadoras do Vírus da imunodeficiência humana 1 (HIV-1) do Estado do Pará, e Tocantins

A prevalência da infecção por agentes virais, como o HTLV, o VHB e o CMV ainda é pouco conhecida na população de mulheres grávidas portadoras do HIV-1 na Região Norte do Brasil. Este trabalho teve como objetivo descrever a soroprevalência das infecções pelo HTLV, CMV e VHB em grávidas portadoras do HIV-1 atendidas em um centro de referência do Pará e de Tocantins. Foram coletas amostras de sangue de 47 mulheres grávidas portadoras do HIV-1, procedentes de várias localidades do estado do Pará, no período de agosto de 2005 a janeiro de 2008 e de 18 mulheres grávidas portadoras do HIV-1 oriundas de várias localidades do estado de Tocantins no período de maio a outubro de 2007. As amostras foram submetidas a um ensaio enzimático do tipo ELISA para a detecção de anticorpos anti-HTLV, anti-VHB (anti-HBc total, anti-HBc IgM, anti-HBs, HBsAg) e anti-CMV IgM/IgG. A análise sorológica revelou que nenhuma das amostras de soro de ambos os estados foi positiva para o anti-HTLV e anti-CMV IgM. Entretanto, todas as amostras de ambos os estados apresentaram anticorpos anti-CMV IgG. A prevalência da infecção pelo VHB em grávidas portadoras do HIV-1 do estado do Pará foi de 19,1% e em Tocantins essa prevalência foi de 27,8%. Apenas no Estado de Tocantins verificamos que houve apenas uma grávida (5,6%) co-infectada HIV-1/VHB. A prevalência da co-infecção HIV/HTLV é baixa nas populações examinadas, assim como a ocorrência da infecção aguda pelo CMV. Entretanto, verificou-se um grande número de mulheres de ambos os estados ainda suscetíveis à infecção pelo VHB, o que sugere que estas populações devam ser vacinadas contra o VHB.

Spectroscopic, Structural, and Conformational Properties of (Z)-4,4, 4-Trifluoro-3-(2-hydroxyethylamino)-1-(2-hydroxypheny1)-2-buten-1-one, C12H12F3NO3: A Trifluoromethyl-Substituted beta-Aminoenone

The ( Z)-4,4,4-trifluoro-3-(2-hydroxyethylamino)-1-(2-hydroxyphenyl)-2-buten-1-one (C12H12F3NO3) compound was thoroughly studied by IR, Raman, UV-visible, and C-13 and F-19 NMR spectroscopies. The solid-state molecular structure was determined by X-ray diffraction methods. It crystallizes in the P2(1)/c space group with a = 12.1420(4) angstrom, b = 7.8210(3) angstrom, c := 13.8970(5) angstrom, beta = 116.162(2)degrees, and Z = 4 molecules per unit cell. The molecule shows a nearly planar molecular skeleton, favored by intramolecular OH center dot center dot center dot 0 and NH center dot center dot center dot 0 bonds, which are arranged in the lattice as an OH center dot center dot center dot 0 bonded polymer coiled around crystallographic 2-fold screw-axes. The three postulated tautomers were evaluated using quantum chemical calculations. The lowest energy tautomer (I) calculated with density functional theory methods agrees with the observed crystal structure. The structural and conformational properties are discussed considering the effect of the intra- and intermolecular hydrogen bond interactions.
