13. Cefaleia na gestação
There are little epidemiologic studies about headache in women; therefore, from January/1998 to June/2002 we prospectively evaluated 1101 pregnant women between 12-45 years of age, with a history of headache, at two prenatal clinics and an inpatient obstetric public hospital. The main purpose was to evaluate the presence of headache in women with previous hi

14. Efecto de solvente sobre la descomposición térmica de trans-3,6-dimetil-3,6-difenil-1,2,4,5-tetraoxaciclohexano en solución
The thermal decomposition reaction of trans-3,6-dimethyl-3,6-diphenyl-1,2,4,5-tetraoxacyclohexane (acetophenone cyclic diperoxide, DPAF), in different solvents (methanol, 1,4-dioxane, acetonitrile and 2-propanol/benzene mixtures) in the initial concentration and temperature ranges of (4.2-10.5) x 10-3 M and 140.0 to 185.0 ºC, respectively, follows a pseudo

15. Physical-chemical, nutritional and biological evaluation of acid, biological and enzymatic silage made from trash fish and fish waste from the processing of Nile tilapia (Oreochromis niloticus). / Avaliação físico-química, nutricional e biológica das silagens ácida, biológica e enzimática elaboradas com descarte e resíduo do beneficiamento da Tilápia do Nilo (Oreochromis niloticus).
In Brazil and around the world, the fish-related industry produces a great amount of waster of high biological value. Due to the lack an adequate use, this residual material is considered a problem from the sanitary, environmental and production efficiency perspectives. With the objective of minimizing environmental problems and increasing fish production ef

16. IS1245 restriction fragment length polymorphism typing of Mycobacterium avium from patients admitted to a reference hospital in Campinas, Brazil
Mycobacterium avium is an important pathogen among immunodeficient patients, especially patients with AIDS. The natural history of this disease is unclear. Several environmental sources have been implicated as the origin of this infection. Polyclonal infection with this species is observed, challenging the understanding of its pathogenesis and treatment. In

17. Role of Tamm-Horsfall protein and uromodulin in calcium oxalate crystallization
One of the defenses against nephrolithiasis is provided by macromolecules that modulate the nucleation, growth, aggregation and retention of crystals in the kidneys. The aim of the present study was to determine the behavior of two of these proteins, Tamm-Horsfall and uromodulin, in calcium oxalate crystallization in vitro. We studied a group of 10 male ston

18. Non-tuberculous mycobacteria I: one year clinical isolates identification in Tertiary Hospital Aids Reference Center, Rio de Janeiro, Brazil, in pre highly active antiretroviral therapy era
The aim of this study was to determine the prevalence of non-tuberculous mycobacteria (NTM) isolates at University Hospital, Reference Center for Aids in Rio de Janeiro, Brazil, during one year. We used standard biochemical tests for species identification and IS1245 PCR amplification was applied as a Mycobacterium avium specific identification marker. Four

19. Descomposicion termica del diperoxido de pinacolona (3,6-diterbutil-3,6-dimetil-1,2,4,5-tetraoxaciclohexano) en solución de 2-metoxietanol
The thermal decomposition reaction of pinacolone diperoxide (DPP; 0.02 mol kg-1) in 2-methoxyethanol solution studied in the temperature range of 110.0-150.0 °C, follows a first-order kinetic law up to at least 50% DPP conversion. The organic products observed were pinacolone, methane and tert-butane. A stepwise mechanism of decomposition was proposed where

20. Multiple isolates from Aids patients: aspects of an analysis by a genotypic marker and antimicrobial susceptibilities variations
Twenty-one Mycobacterium avium multisolates, from ten human immunodeficiency virus-infected patients, were typed by restriction fragment length polymorphism using as marker the IS1245 and characterized by minimum inhibitory concentration for nine different antibiotics. Two out of four patients harboring multisolates with different fingerprint profile, were t

21. Characterization of IS1245 for Strain Typing of Mycobacterium avium
IS1245 is an insertion element widely prevalent among isolates of Mycobacterium avium. We used PvuII Southern blots to analyze IS1245 polymorphisms among 159 M. avium isolates (141 clinical isolates from 40 human immunodeficiency virus-infected patients plus 18 epidemiologically related environmental isolates) that represented 40 distinct M. avium strains, a

22. Typing of Human Mycobacterium avium Isolates in Italy by IS1245-Based Restriction Fragment Length Polymorphism Analysis
All but 2 of 63 Mycobacterium avium isolates from distinct geographic areas of Italy exhibited markedly polymorphic, multibanded IS1245 restriction fragment length polymorphism (RFLP) patterns; 2 isolates showed the low-number banding pattern typical of bird isolates. By computer analysis, 41 distinct IS1245 patterns and 10 clusters of essentially identical

23. A novel insertion element from Mycobacterium avium, IS1245, is a specific target for analysis of strain relatedness.
The insertion sequence IS1245 is a novel mycobacterial repetitive element identified in Mycobacterium avium. It encodes a transposase which exhibits a 64% amino acid similarity with IS1081, an insertion element present in the M. tuberculosis complex. The host range of IS1245 appears limited to M. avium as this element was not identified in M. intracellulare

24. IS1311 and IS1245 Restriction Fragment Length Polymorphism Analyses, Serotypes, and Drug Susceptibilities of Mycobacterium avium Complex Isolates Obtained from a Human Immunodeficiency Virus-Negative Patient
Six isolates of Mycobacterium avium of genotype dnaJ+ IS901− IS1311+ IS1245+ and serotypes 6 (n = 1), 6/9, (n = 2), and 9 (n = 3) were obtained within a 5-month period from a human immunodeficiency virus-negative patient treated for tuberculosis. The isolates were identified with PvuII restriction fragment length polymorphism (RFLP) analysis as a single IS
