Retroviroses em felinos domésticos

The retrovirus are recognized as pathogenic group of virus for domestic animals. The particularitities of these viruses are the necessity of the enzyme transcriptase reversa, for the conversion of the viral RNA in viral DNA (provirus) and the incorporation in the DNA of the cell, what it confers to the infection the lifetime character, due to all the infected cells present the provirus our DNA. Among the retroviruses in domestic felines, the leukaemia and immunossupressive virus represent the more important diseases. The main form of transmission of the virus of the FeLV is occur by close contact and the saliva presents high viral concentration. For the FIV, the main form of transmission is represented by wounds of bite. The retrovírus, replicate mainly in high metabolization cells. The infection for FeLV cause mieloproliferativas and degenerative illnesses, while the FIV are related imunossupressora illness. The treatment for these retroviroses is symptomatic associated to imunomodulatory drugs, none of these drugs are capable to eliminate the virus. For the prevention of these retrovirus are used vaccines. However only the vaccine against FeLV have showed efficiency. Thus , the more important measures in control of these diseases is prevent the contact between infected and health felines. The ain of present study was reviewed the more important aspects of retroviruses in domestic felines, with emphasis to virulence properties, epidemiology, fisiopathogeny, clinical manifestations, methods of diagnosis, therapy, and control measures

Principais marcadores utilizados na avaliação da qualidade do sêmen de animais domésticos

Methods of semen cryopreservation allow changes in spermatic cells, such as damage in plasma and acrossomal membrane and modifications in mitochondrial function due to a disorder in the lipidic bilayer. For effective oocyte fertilization, spermatozoa require functional competent membranes, and intact organelles, acrosome and DNA. However, most laboratory methods used to evaluate semen quality are not highly correlated with fertilizing capacity. The discovery of a variety of fluorochromes and compounds conjugated to fluorescent probes has enabled an accurate assessment of the viability, integrity and function of spermatozoa. Among the most used probes that label the various compartments of the sperm cell there are the membrane impermeable fluorescent dyes to test the membrane integrity, as well as acylated dyes that pass the intact membrane. For the acrossomal integrity the most commonly used method is lectins labeled by a fluorescent probe. The acrosome reaction and spermatic capacitation is detected by the evaluation of membrane architecture and disorder of lipids in plasma membrane. Mitochondrial function can be determined using markers for their aerobic activity. The DNA status of spermatozoa has been determined using the metachromatic properties of Acridine Orange, and the DNA fragmentation can also be assessed by TUNEL assay. Finally, DNA condensation is analyzed using a single cell DNA gel electrophoresis assay that indicates DNA compactation. This monograph aims to compile the various tests used to detect damaged spermatozoa under cryopreservation methods, searching for improve the predictive value of semen analysis with the intention of a successful conception

Proposição de modelo de logística reversa de resíduos sólidos domésticos recicláveis para o municípios de Rio Claro - SP

The approval of the Solid Waste National Policy on August 2, 2010, brought important advances on the issue of solid waste nationwide. Several requirements were imposed causing public and private sectors to direct the problem more diligently. At the same time, the growth of human consumption and the negative impacts of related activities are increasing pressure for new ways to manage wastes. This study was carried out in order to bring proposals for a new model of solid waste management in the city of Rio Claro. To do so, it was used methodologies which stick to collaborative approaches in order to co-create a new vision considering different points of view . This new proposal includes four main initiatives: the integration of a reverse logistics system and collection of recycling materials in all kinds of educational institutions; the use of a routing platform for collection of solid wastes and recycling materials; the application of a garbage fee to residents who use the collection of solid waste system; and a bonus system developed by the private sector as a marketing strategy, encouraged by the public sector, enabling residents to separate their wastes correctly and leave them in one of the educational institutions to exchange points for discounts at local markets
