1. Seronegative cat-scratch disease diagnosed by PCR detection of Bartonella henselae DNA in lymph node samples
Cat scratch disease (CSD), the typical clinical manifestation of Bartonella infections usually follows a typical benign self-limited course. Nevertheless, a variety of unusual clinical manifestations and confusing imaging features can lead to misinterpretations and render the disease a diagnostic dispute. Routine laboratory tests exhibit varying reported sen

2. Sistema automÃtico para anÃlise de variabilidade da freqÃencia cardÃaca / Automatic system for analysis of heart rate variability
This dissertation describes a system for analysis of heart rate variability through metrics on time and frequency domain and by non-linear methodology, which is initiated by the process of segmentation of the QRS complex of the electrocardiogram signal. The motivation for this work is the analysis of the influence from the algorithms of beat segmentation and

3. Monitoring fails in tubes using signals digital processing / Sistema de monitoramento de falhas em tubulações por meio de processamento digital de sinais
Natural gas has hazardous contaminants that, besides being corrosive, compromise the quality for the consumption. For in such a way the present residual water condensation in the gas can start a local corrosive process, which could cause damage to the structure of the gas ducts. Due to the great length of a gas duct, corrosive components decrease its quality

4. Ontositter: sistema de soluÃÃo de problemas de SAGBD baseado em ontologia
Currently the Database Management System (DBMS) possess great capacity to store since the data gotten for the systems do business until the information synthecized for the systems of decision taking. In this context, as much the search for the information how much the routines of maintenance of this environment require a bigger effort on the part of the data

5. Evaluation of techniques for the diagnosis of Strongyloides stercoralis in human immunodeficiency virus (HIV) positive and HIV negative individuals in the city of Itajaí, Brazil
Human immunodeficiency virus (HIV) and intestinal parasites are common in Brazil. Previous studies have shown that infection with Strongyloides stercoralis is frequently associated with HIV infection. Strongyloidiasis is difficult to diagnosis and stool examination with conventional techniques fails to detect the helminth larvae. We made a prospective study,

6. A dynamic method to PEBS detection and the Shadowing Method to calculate the controlling unstable equilibrium point in transient stability studies / Método dinâmico para detecção do PEBS e "Shadowing Method" para cálculo do ponto de equilíbrio de controle em estudos de estabilidade transitória
In transient stability assessment, the nonlinearities of the systems and the dimension of the problem contribute to the complexity of the analysis in power systems. The classical numerical solution to obtain the critical clearing time (cct) has been used, but it is time-consuming and not adequate for real-time applications. The direct methods have the adequa

7. Comparison of monoclonal antibodies for rapid detection of cytomegalovirus in spin-amplified plate cultures.
Cytomegalovirus (CMV) was detected in 56 of 275 specimens (20%); 50 of 56 (89%) were detected by conventional culture, and 37 (66%) were detected by rapid assay at 72 h with a commercial monoclonal antibody and a pooled monoclonal antibody. Although the two antibodies were equally sensitive at 72 h, the pooled antibody gave a brighter, more easily detected s

8. Viral Dynamics during Structured Treatment Interruptions of Chronic Human Immunodeficiency Virus Type 1 Infection
Although antiviral agents which block human immunodeficiency virus (HIV) replication can result in long-term suppression of viral loads to undetectable levels in plasma, long-term therapy fails to eradicate virus, which generally rebounds after a single treatment interruption. Multiple structured treatment interruptions (STIs) have been suggested as a possib

9. Adult and fetal human globin genes are expressed following chromosomal transfer into MEL cells.
Somatic cell hybridization of mouse erythroleukemia (MEL) cells and HEL cells, a human erythroleukemia line that produces fetal (gamma) but fails to express adult (beta) globin, was used to test whether the expression of the two human globin genes is regulated cis or trans. An experimental approach using anti-human globin monoclonal antibodies for detection,

10. Superiority of Amphotericin over Nystatin in Thayer-Martin Medium
Vaginal and cervical specimens taken for the detection of gonorrhea frequently contain Candida albicans. Thayer-Martin medium containing nystatin (VCTN) is unsatisfactory because nystatin fails to selectively inhibit C. albicans. Thayer-Martin medium containing no nystatin was prepared with varying concentrations of amphotericin (VCTA) added, and this latter

11. Pheasant virus: new class of ribodeoxyvirus.
Cocultivation of cells derived from embryos of golden pheasants or Amherst pheasants with chicken embryo cells infected with Bryan strain of Rous sarcoma virus resulted in the detection of viruses which appear to be endogenous in these pheasant cells. The pheasant viruses (PV) were similar to avian leukosis-sarcoma viruses (ALSV) in their gross morphology, i

12. A quantitative assay measuring the function of lipase maturation factor 1
Newly synthesized lipoprotein lipase (LPL) and related members of the lipase gene family require an endoplasmic reticulum maturation factor for attainment of enzyme activity. This factor has been identified as lipase maturation factor 1 (Lmf1), and mutations affecting its function and/or expression result in combined lipase deficiency (cld) and hypertriglyce
