Comparative Study Between Serology And Nucleic Acid Tests - Bok av Marcela de Lacerda Valença Queiroz - Häftad

Comparative Study Between Serology And Nucleic Acid Tests - Bok av Marcela de Lacerda Valença Queiroz - Häftad

Serological tests for HIV and HCV are based on the detection of antibodies present in the donor's blood. This is what is known as the immunological window, a period in which, even if infected, the individual's serology is negative. The aim was to carry out a comparative study with a critical analysis of the screening methodologies for HIV and HCV testing in donors at the Hematology and Hemotherapy Center of the State of Piauí - HEMOPI. The comparison between the methodologies showed that although..

VITAMINS B1 AND B2, OUR INTELLECTUAL AND PHYSICAL TONIC - Bok av Boko Pascal Akabassi - Häftad

VITAMINS B1 AND B2, OUR INTELLECTUAL AND PHYSICAL TONIC - Bok av Boko Pascal Akabassi - Häftad

Vitamin B1 has the molecular formula C12H17N4OS. It is a metabolic precursor of thiamine pyrophosphate, the form activated in the liver, which enables carbohydrates to be converted into energy and ensures proper functioning of the nervous and muscular systems. Synthesized by bacteria, plants and fungi, it is involved in energy metabolism, mood regulation, heart failure and muscle pain. Vitamin B2 is required for the synthesis of flavin adenine dinucleotide and flavin mononucleotide. It is most often..

Anticorrosive performance of paints in accelerated tests - Bok av David Domingos Soares Da Silva - Häftad

Anticorrosive performance of paints in accelerated tests - Bok av David Domingos Soares Da Silva - Häftad

Corrosion of metallic materials, especially carbon steel, is a major problem, as it occurs frequently in a wide variety of activities, such as the chemical, oil and gas, construction and automotive industries, among others. The economic losses incurred by these activities are enormous, which is why it is necessary to study in depth and use methods that can combat corrosion of metallic material. The most common way to combat corrosion is to paint the part, using paints that are basically composed..

Effects of aminophylline combined with ethanol on neurochemical tests - Bok av Paula Matias Soares - Häftad

Ethanol is a substance that has been used since ancient times and causes alterations in different tissues, including the Central Nervous System (CNS). Its abuse and continued use leads to the development of different pathologies, as it is a highly degenerative drug. Preliminary studies have shown that aminophylline, a non-selective adenosine receptor antagonist, interferes with the ethanol action pathway in different areas of central signalling. Based on these results, this study highlighted aminophylline..

Evaluation of corrosion protection of paints in non-accelerated tests - Bok av David Domingos S. Da Silva - Häftad

Evaluation of corrosion protection of paints in non-accelerated tests - Bok av David Domingos S. Da Silva - Häftad

Corrosion in metallic materials occurs because there is a tendency for the metal produced to revert to its original state (oxide form) and lower free energy, causing deterioration of the material properties, with consequent structural impairment. To prevent corrosion, several forms of substrate protection are used, one of the most important being the application of paints, which provides a protective film that is not harmful to the metal surface. In order to evaluate the degree of degradation of..
