13. Influência do diabetes experimental na disposição cinética e no metabolismo estereosseletivos do tramadol em ratos / Influence of experimental diabetes on the kinetic disposition and stereoselective metabolism of trans-tramadol in rats.
O trans-tramadol (trans-T), é um analgésico de ação central disponível na clínica como mistura racêmica dos enantiômeros (+)-trans-T e (-)-trans-T. O trans-T é biotransformado pelo CYP2D ao metabólito ativo O-desmetiltramadol (M1) e pelo CYP2B e CYP3A ao metabólito inativo N-desmetiltramadol (M2). O estudo investiga a influência do diabetes exper

14. Diagnóstico precoce de neoplasia endócrina múltipla tipo 2B: um desafio para os médicos
A forma hereditária do carcinoma medular da tiróide pode ocorrer de modo isolado, o carcinoma medular da tiróide familiar (FMTC), ou como parte das neoplasias endócrinas múltiplas tipo 2A (MEN2A) e 2B (MEN2B). MEN2B é uma síndrome rara e seu fenótipo é usualmente, mas nem sempre, notado pelo médico. Na infância, nenhuma das características de MEN

15. Estudo fitoquímico de Euxylophora paraensis e avaliação das substâncias isoladas frente à enzima gliceraldeído-3-fosfato desidrogenase de Trypanosoma cruzi / PHYTOCHEMICAL STUDY OF Euxylophora paraensis AND EVALUATION OF SUBSTANCES ISOLATED FRONT OF GLYCERALDEHYDE-3-PHOSPHATE DEHYDROGENASE OF Trypanosoma cruzi
This work describe the phytochemical study of bark and leaves of the specie E. paraensis (Rutaceae). This dissertation aims at contributing with the chemistry of the Rutaceae family and evaluation of the antichagasic activity of substances isolated. The phythochemical study allowed to isolate fifteen secondary metabolites belonging to different classes: two

16. Response activity of alveolar macrophages in pulmonary dysfunction caused by Leptospira infection
Leptopspirosis is a syndrome with different clinical manifestations including the most severe and often fatal forms of pulmonary disease of unknown etiology. Pulmonary injury during the inflammatory process has been associated with the excessive number of alveolar macrophages (AMs) and polymorphonuclear leukocytes stimulated in the lungs and with the product

17. Effect of age on upper and lower eyelid saccades
To study the effect of age on the metrics of upper and lower eyelid saccades, eyelid movement of two groups of 30 subjects each were measured using computed image analysis. The patients were divided on the basis of age into a younger group (20-30 years) and an older group (60-91 years). Eyelid saccade functions were fitted by the damped harmonic oscillator m

19. Maternal translocation (9;18) with two abnormal offspring each with different chromosome derivatives.
We report a phenotypically normal woman with an apparently balanced reciprocal translocation between chromosomes 9 and 18 [46,XX,t(9;18)(p22;p11.2)], giving rise to unbalanced chromosome complements in two of her children, each of whom received a different derivative chromosome. The proband's karyotype is 46,XY,-18,+der(18), t(9;18)(p22;p11.2)mat, which resu

20. Evaluation of the MB/BacT system and comparison to the BACTEC 460 system and solid media for isolation of mycobacteria from clinical specimens.
The MB/BacT automated system is designed for the isolation of mycobacteria from clinical specimens. It utilizes a colorimetric sensor and reflected light to continuously monitor the CO2 concentration in the culture medium. We compared its performance to that of the BACTEC 12B media for the radiometric BACTEC 460 instrument and that of solid culture media. Re

21. Expression of hepatitis B virus middle and large surface antigen genes in Saccharomyces cerevisiae.
The hepatitis B virus genome carries the surface antigen (SAg) gene and an open reading frame that encodes two SAg-related polypeptides: SAg with a 55-amino-acid N-terminal extension polypeptide and SAg with a 174-amino-acid N-terminal extension polypeptide. These are termed middle S and large S, respectively. These polypeptides or their glycosylated derivat

22. Controlled comparison of the BacT/Alert and BACTEC 660/730 nonradiometric blood culture systems.
In a collaborative study at three university hospitals, the recovery of microorganisms and the speed of detection of microbial growth by the BacT/Alert (Organon Teknika Corporation, Durham, N.C.) and BACTEC 660/730 (Becton-Dickinson Diagnostic Instrument Systems, Sparks, Md.) nonradiometric blood culture systems were compared. A total of 5,918 comparisons we

23. Improved detection of bacterial growth in continuous ambulatory peritoneal dialysis effluent by use of BacT/Alert FAN bottles.
Culture-negative peritonitis is a major complication for patients on continuous ambulatory peritoneal dialysis (CAPD) and precludes organism-specific therapy. The aim of the present study was to compare inoculation of 10 ml of CAPD effluent into BacT/Alert blood culture bottles (FAN [fastidious antimicrobic neutralizing], BacTAlert aerobic [BTA], and BacT/Al

24. Direct observations of the effects of baroreceptor stimulation on skeletal muscle circulation of the rat.
1. In anaesthetized rats, supramaximal baroreceptor stimulation by carotid sinus inflation evoked a reflex fall in arterial pressure and an increase in vascular conductance and flow of muscles of the hindquarters. 2. Simultaneously, main arteries, primary and secondary arterioles (13-90 microns, internal diameter (i.d.)) and terminal arterioles (7-13 microns
