14. Costs of genetic testing: Supporting Brazilian Public Policies for the incorporating of molecular diagnostic technologies
This study identifies and describes the operating costs associated with the molecular diagnosis of diseases, such as hereditary cancer. To approximate the costs associated with these tests, data informed by Standard Operating Procedures for various techniques was collected from hospital software and a survey of market prices. Costs were established for four

15. Aspidosperma subincanum II. Usefulness of uleine and ribonucleic fragments in the treatment of AIDS patients
Aids patients were treated during a year with three different food supplements commercially available: para-pau-aspido (Aspidosperma subincanum Mart. ex A. DC., Apocynaceae); 2Leid (nucleic acids and cytokines); and Para Immuno (propolis, pollen and royal jelly). All foods, given either alone or in combination, proved useful to all AIDS patients who received

16. An Alternative and Rapid Method for the Extraction of Nucleic Acids from Ixodid Ticks by Potassium Acetate Procedure
Four variants of the potassium acetate procedure for DNA extraction from ixodid ticks at different stage of their life cycles were evaluated and compared with phenol-chloroform and ammonium hydroxide methods. The most rapid and most efficient variant was validated in the DNA extraction procedure from the engorged ticks collected from bovine, canine as well a

17. Superparamagnetic maghemite loaded poly (ε- caprolactone) nanocapsules : characterization and synthesis optimization
Iron oxide nanoparticles (ION) have been studied for essential applications, like detection of biological constituents (virus, bacterials, cell, nucleic acids, protein, enzyme, etc.), magnetic bioseparation and clinic therapy and diagnosis (such as MRI magnetic fluid and hyperthermia). In this work, γ-Fe2O3has been synthetized by a adapted sol-gel method a

18. Target-directed catalytic metallodrugs
Most drugs function by binding reversibly to specific biological targets, and therapeutic effects generally require saturation of these targets. One means of decreasing required drug concentrations is incorporation of reactive metal centers that elicit irreversible modification of targets. A common approach has been the design of artificial proteases/nucleas

19. Desenvolvimento de vetores não virais para entrega gênica baseados na cadeia leve de dineína Rp3 = : Development of non viral vectors for gene delivery based on dynein light chain Rp3 / Development of non viral vectors for gene delivery based on dynein light chain Rp3
Gene delivery is a promising technique with great medical potential that consists in the introduction of exogenous nucleic acids, and can be applied for gene therapy as well as DNA vaccination. However, its use is still limited by the lack of an ideal delivery vector, which is both safe and efficient. Although much more effective, viral vectors still raise s

20. DETECÇÃO DE ÁCIDOS NUCLÉICOS (DNA) DE Neospora caninum EM TECIDOS DE GERBILS (Meriones unguiculatus) SUBMETIDOS À INFECÇÃO AGUDA E CRÔNICA / DETECTION OF NUCLEIC ACIDS (DNA) OF Neospora caninum IN TISSUES OF GERBILS (Meriones unguiculatus) SUBMITED TO ACUDE AND CHRONIC INFECTIONS
A neosporose é uma enfermidade de grande importância econômica, encontra-se distribuída em todo o mundo e pode ser considerada atualmente, umas das maiores causas de aborto e perdas neonatais em bovinos. A patogenia da infecção pelo Neospora caninum não está totalmente esclarecida e algumas questões a este respeito são importantes para determinar m

21. A química da vida como nós não conhecemos
It has been widely suggested that life based on carbon and water is the only plausible biochemistry, and specifically that terrestrial biochemistry of nucleic acids, proteins, and sugars is likely to be universal. However, according to our current knowledge of physics and chemistry, this may be just a geocentric concept. In recent decades, laboratory experim

22. Viral inactivation in hemotherapy: systematic review on inactivators with action on nucleic acids
The aim of this study was to conduct a systematic review on the photoinactivators used in hemotherapy, with action on viral genomes. The SciELO, Science Direct, PubMed and Lilacs databases were searched for articles. The inclusion criterion was that these should be articles on inactivators with action on genetic material that had been published between 2000

23. Estudo molecular de pestivirus em amostras de cultura celular e soro de pequenos ruminantes. / Estudo molecular de pestivirus em amostras de cultura celular e soro de pequenos ruminantes.
The Ruminants Pestiviruses are often associated with temporary and subclinical or mild clinical signs, with the largest losses related to the infection of pregnant females that can cause fetal loss and birth of persistently infected (PI) animals. The Pestivirus are distributed in many countries, including Brazil, where studies in goats and sheep are scarce.

24. Magnetic bead technology for viral RNA extraction from serum in blood bank screening
Nucleic acid amplification testing (NAT) was recently recommended by Brazilian legislation and has been implemented at some blood banks in the city of São Paulo, Brazil, in an attempt to reduce blood-born transmission of human immunodeficiency virus (HIV) and hepatitis C virus. OBJECTIVE: Manual magnetic particle-based extraction methods for HIV and HCV vir
