Composição química e toxicidade de óleos essenciais para o pulgão-verde Schizaphis graminum (Rondani, 1852)

Este trabalho teve como objetivo identificar e quantificar os constituintes dos óleos essenciais de Illicum verum, Ageratum conyzoides, Piper hispidinervum e Ocotea odorifera, bem como avaliar a toxicidade para o pulgão-verde Schizaphis graminum. A qualificação dos constituintes foi realizada por meio de um cromatógrafo gasoso + espectrômetro de massas, e a quantificação, por um cromatógrafo gasoso + detector de ionização de chama, ambos com uma coluna DB5. O método de hidrodestilação promoveu um rendimento (p/p) de 3,81% para I. verum, 0,46% para A. conyzoides, 2,85% para P. hispidinervum e 0,68% para O. odorífera. Já os componentes majoritários foram: precoceno (87,0%) e (E)-cariofileno (7,1%) para A. conyzoides; (E)-anetol (90,4%), limoneno (2,6%) e metil-chavicol (1,3%) para I. verum; metil-eugenol (81,2%) e safrol (10,6%) para Ocotea odorífera; e safrol (82,5%) e α-terpinoleno (13,4%) para P. hispidinervum. Pelos testes de toxicidade aguda (24 horas) com folhas de sorgo ou papel-filtro contaminados, verificou-se que o óleo de A. conyzoides foi o mais tóxico para o pulgão, com CL50 de 7,13 e 7,08 µL óleo/cm2 respectivamente, seguido por O. odorifera com CL50 de 11,80 e 103,00 µL óleo/cm2 respectivamente; I. verum de 51,80 µL óleo/cm2 em ambos os substratos; e o menos tóxico foi o óleo essencial de P. hispidinervum, com CL50 de 62,50 e 143,00 µL óleo/cm2, respectivamente. Dessa maneira, sugere-se que o uso dos óleos essenciais pode representar uma nova ferramenta em programas de manejo integrado de pragas.

Alcohol and Quality of Life Among Social Groups for the Elderly in Sao Jose dos Campos, Brazil

This study aims to investigate alcohol consumption within social groups for the elderly in So Jos, dos Campos-Brazil, and to check for a correlation between alcohol consumption and quality of life. A sample of 500 individuals participating on social groups for the elderly were interviewed by using the Alcohol Use Disorders Identification Test (AUDIT) to verify alcohol consumption; the Medical Outcomes Study 36 Item Short Form (SF-36), for evaluating quality of life; and the Oral Health Impact Profile short form (OHIP-14), for evaluating oral health-related quality of life. The average alcohol consumption was very low (1.48), being higher in men (2.23) than women (1.09). The SF-36 average score for the domain of physical function was 70.5; for role-physical function 64.9; for bodily pain,68.3; for general health 73.8; for vitality,72.4; for social function 82.8; for role-emotional function 72.3 and for mental health 75.0. The OHIP-14 average score was 3.87. AUDIT did not correlate with SF-36 domains, or with OHIP-14. However, there was a negative correlation between OHIP 14 and all SF-36 domains. This elderly sample has a very low consumption of alcohol, and no correlation was found between alcohol consumption and oral and medical quality of life.

Uso de resíduos de madeiras e frutos da amazônia para o cultivo in vitro do cogumelo comestível shiitake

Local abundant residues with low or without commercial value with potential to make the production of edible mushrooms economically viable in any region of Brazil must be employed for cultivation. Thus, the radial mycelial growth of LED 20 strain of Lentinula edodes (Berk.) Pegler was verified in culture media prepared with extract of regional residues by using substrates based on Protium puncticulatum, Cariniana micrantha and Caryocar glabum sawdust, supplemented with 20% of grinded residues from the barks of the fruits of Astrocaryum aculeatum and Theobroma grandiflorum. Residues from eucalyptus (Eucalyptus spp) sawdust and wheat bran (Triticum aestivum L) were used as witness because they are commonly used in the cultivation of L. edodes. The experimental design used was totally randomized, in 4x3 factorial scheme, totalizing 12 treatments with five repetitions, being that each repetition corresponded to a Petri dish, adding up a total of 60 dishes, which were incubated under 25 degrees C. The diameter of the colony was daily evaluated during seven days of incubation. After that period, it was verified that media prepared with P. puncticulatum extract, whose supplementation with both brans was favorable for fungic development, presented some of the highest averages of mycelial growth of LED 20 strain of L. edodes, confirming the potential of those residues.

Efeito das cargas de treinamento sobre parâmetros fisiológicos de futebolistas

The aim of this study was to investigate the effects of three weeks of training with intensity monitored on the aerobic capacity of professional soccer players. Fourteen players, members of a first division Brazilian Championship team in 2010, aged 22.78 +/- 3.06 years were evaluated pre and post three weeks of training. The anaerobic threshold intensity LAn was determined by bi-segmented method, for this four submaximal efforts of 800 meters with intensities 10, 12, 14 and 16 km/h were applied. Thirty three training sessions were quantified in zones according to heart rate related to the LAn (FCLAn): Z1 - 10% below, Z2 - 90-100% and Z3 - above the FCLAn. During training participants remained 31.17 +/- 14.86%, 42.96% and 25.87 +/- 14.90 +/- 16.67% in Z1, Z2, and Z3 respectively. There were no significant differences in the LAn (pre = 13,29 +/- 0,71 km.h(-1); post = 12,85 +/- 0,90 km.h(-1)), perceived exertion (pre = 11,53 +/- 1,45 u.a; post = 11,23 +/- 1,53 u.a) and FCLAn (pre = 166,64 +/- 10,69 bpm; post = 174,50 +/- 10,89 bpm) between conditions before and after training, indicating that three weeks of training are insufficient to generate positive changes in soccer players LAn.

Analysis of rocuronium in human plasma by liquid chromatography-tandem mass spectrometry with application in clinical pharmacokinetics

Rocuronium (ROC) is a neuromuscular blocking agent used in surgical procedures which is eliminated primarily by biliary excretion. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for analysis of ROC in human plasma. Separation of ROC and IS (verapamil) was performed using an endcapped C-18 column and a mixture of water:acetonitrile:trifluoracetic acid (50:50:0.1, v/v) as mobile phase. Aliquots of 100 mu L of human plasma were extracted at pH 3, using dichloromethane. The lower limit of quantification of 5 ng/mL shows the high sensitivity of this method. Intra- and inter-assay precision (as relative standard deviation) was all <= 14.2% and accuracy (as relative standard error) did not exceed 10.1%. The validated method was successfully applied to quantify ROC concentrations in patients under surgical procedures up to 6 h after the administration of the 0.4-0.9 mg/kg ROC. The pharmacokinetic parameter estimations of ROC showed AUC/dose of 563 mu g min/mL, total clearance of 2.5 mL/min/kg, volume of distribution at steady state of 190 mL/kg and mean residence time of 83 min.
