O uso do poder de compra do estado como instrumento de política pública: a lei complementar nº 123/2006, sua implementação

This study aims to bring back the debate on the use of the purchasing power of the State as instrument to boost other public policies established by federal entities. Besides putting it in a context of innovation in the public sector, the study of this issue must consider all its variables and questions, whwther of legal, economic, social or political order, starting with the one I consider the most important: the possibility of the State to assert its power of puchasing in order to design and promote markets, searching to achieve other objectives rather than those traditionally accepted. Thus, in the analysis of a direct application of a new practice, this study evaluates the implementation of the Additional Law number 123/06, which gives a differentiating treatment to micro and small enterprises in public contracting. By means of interviews, information was collected with the relevant actors in in this phase. The conclusion was that aspects such as the heterogeneity of the segment of the MPE`s and their low capacity of articulation, along with the endogenous obstacles of the instituion of the bidding, contribute decively to the low stage of the implementation that occurs at this moment.

Avaliação do teste do anel em leite na vigilância epidemiológica da brucelose bovina em rebanhos e em laticínios

Analisaram-se 464 amostras individuais de leite e 54 amostras de leite de latões, oriundos de leite dos mesmos animais, por meio do teste do anel do leite (TAL) visando à sua aplicação no diagnóstico individual e de rebanhos da brucelose bovina. Foram também avaliadas 464 amostras de soro sangüíneo por meio de provas do antígeno tamponado acidificado (ATA), soroaglutinação lenta em tubos (SAL) e 2-mercaptoetanol (2-ME), todas para brucelose. Cento e vinte e três amostras (26,5%) testadas pelo TAL apresentaram resultados positivos. Dessas, 30 resultaram positivas ao ATA, 28 ao ATA, à SAL e ao 2-ME e 18 à SAL. Das amostras positivas ao TAL, 95 pertenciam a animais sorologicamente negativos ao 2-ME, caracterizando 77,2% (95/123) das reações falso-positivas; dos resultados negativos ao TAL, 4 pertenciam a animais sorologicamente positivos, caracterizando 1,2% (4/341) de reações falso-negativas no TAL individual. Das 54 amostras de leite de latões analisadas pelo TAL, 17 foram consideradas positivas, das quais uma foi caracterizada como falso-positivo, pois todos os animais que a compunham foram negativos ao 2-ME. de 37 latões considerados negativos ao TAL, três continham leite de animais positivos ao 2-ME, caracterizando 8,1% de falso-negativos. O TAL individual demonstrou elevado percentual de resultados falso-positivos, enquanto o TAL em amostras de leite obtidas em latões detectou 84,2% de latões contaminados e 75% de rebanhos infectados.

Análise térmica de esparfloxacino

Sparfloxacin, a third-generation fluoroquinolone, is a potent antibacterial agent against a wide range of Gram-positive and Gram-negative organisms, for example Streptococcus pneumonias, Staphylococcus aureus (including methicillin-resistant strains), Legionella spp., Mycoplasma spp., Chlamydia spp. and Mycobacterium spp. This compound has been submitted to thermal analysis and the results are presented here. The DSC curve of sparfloxacin has an endothermic peak that indicates a melting point at 276.5 °C. The DTA curve of the sample in synthetic air shows two exothermic peaks, at 341.6 and 579.2 °C, attributed to compound decomposition. In the TG curve, the loss of mass can be seen to occur in two steps between 285.5 and 645.3 °C. The DTA curve obtained in a nitrogen atmosphere shows an exothermic peak, with decomposition of sparfloxacin at 340.0 °C; from the corresponding TG plot, the loss of mass starts at 254.4 °C.

Excimer Laser no tratamento do vitiligo em 123 pacientes: estudo retrospectivo

Introduction: Vitiligo is cosmetically disfiguring and can cause significant psychological morbidity. Most therapies require protracted treatments and can lead to disappointing results. More recently, 308 nm Excimer laser has proven to be effective in treating vitiligo. Objective: To analyze the effectiveness and patient satisfaction of 308 nm Excimer treatment for vitiligo patches in a variety of locations on the body. Methods: Patients with generalized or localized vitiligo (n = 123, 321 lesions), were studied. The patients were treated at a private practice between 2007 and 2010. Two independent examiners analyzed the response to the therapy by comparing clinical and photographic records before and after treatment. Results: More than half (n = 77) of the patients presented repigmentation greater than 60%, 26 presented 40-59%, and 20% had levels less than 39%. Facial lesions responded better to treatment than those in other body parts. Elbows, hands and feet were the less sensitive areas. In general, the patients were satisfied with the treatment. Conclusion: The use of Excimer laser for treating vitiligo was effective and safe, producing satisfactory cosmetic results and improving patients' self esteem.

Differential effects of variation in athletes training on myocardial morphophysiological adaptation in men: Focus on I-123-MIBG assessed myocardial sympathetic activity

High intensity systematic physical training leads to myocardial morphophysiological adaptations. The goal of this study was to investigate if differences in training were correlated with differences in cardiac sympathetic activity.58 males (19-47 years), were divided into three groups: strength group (SG), (20 bodybuilders), endurance group (EG), (20 endurance athletes), and a control group (CG) comprising 18 healthy non-athletes. Cardiac sympathetic innervation was assessed by planar myocardial I-123-metaiodobenzylguanidine scintigraphy using the early and late heart to mediastinal (H/M) ratio, and washout rate (WR).Left ventricular mass index was significantly higher both in SG (P < .001) and EG (P = .001) compared to CG without a statistical significant difference between SG and EG (P = .417). The relative wall thickness was significantly higher in SG compared to CG (P < .001). Both left ventricular ejection fraction and the peak filling rate showed no significant difference between the groups. Resting heart rate was significantly lower in EG compared to CG (P = .006) and SG (P = .002). The late H/M ratio in CG was significantly higher compared to the late H/M for SG (P = .003) and EG (P = .004). However, WR showed no difference between the groups. There was no significant correlation between the parameters of myocardial sympathetic innervation and parameters of left ventricular function.Strength training resulted in a significant increase in cardiac dimensions. Both strength and endurance training seem to cause a reduction in myocardial sympathetic drive. However, myocardial morphological and functional adaptations to training were not correlated with myocardial sympathetic activity.

Multiproperty modeling for a set of binary systems. Evaluation of a model to correlate simultaneously several mixing properties of methyl ethanoate+alkanes and new experimental data

[EN] This work makes a theoretical–experimental contribution to the study of ester and alkane solutions. Experimental data of isobaric vapor–liquid equilibria (VLE) are presented at 101.3 kPa for binary systems of methyl ethanoate with six alkanes (from C5 to C10), and of volumes and mixing enthalpies, vE and hE.
