Introduction: The stair-climbing test (SCT) is considered a submaximal test of simple implementation and easy access, which assesses the individual’s functional capacity. Although widely used in surgical patients, there is no standardization regarding the height of the stair and verbal stimulus. Objectives: It was determine if verbal stimulus changes the stair-climbing time (SCt) in individuals over 50 years-old. We compared oxygenation, blood pressure, pulse, respiratory rate and Borg scale between SCT performed with and without stimulation. Methods: We evaluated individuals with ages greater than 50 years-old that performed two STC (with and without verbal stimulation), in the stair with 44 steps, achieving 7.04 m in height and recording the time to climb the stair. The systolic blood pressure (SBP) and the diastolic blood pressure (DBP), respiratory rate (RR), pulse, oxygen saturation (SpO2 ) and Borg scale were evaluated before and after the tests. The time in the SCT with and without stimulation were compared using the Student test-t and the other variables were compared using the ANOVA test (p<0.05). Results: The average age was 59.75±6,40 years old in the 21 evaluated individuals. The time in the SCT without stimulus was significantly higher than the one with stimulus. The SBP, pulse, RR and Borg scale were significantly increased when compared to the SCT with and without stimulus. Oxygenation and DBP didn´t have significant differences at any time of the study. Conclusions: The time in the SCT was lower when performed with verbal stimulus. The SBP, pulse, RR and Borg scale changed significantly after the SCT with and without stimulus, remarking that this change was greater in the SCT with stimulus.

The effort test can be used to assess functional capacity, clinical hemodynamic and metabolic response at the effort, the risk of postoperative pulmonary complications and to assess the response of patients with lung diseases submitted to physiotherapy treatment. Among the stress tests we highlight the Six Minute Test Walk (6 MWT) and Stair Climbing Test (SCT), because they are easy to use and low cost. Especially the SCT is widely used in patients preoperatively. Objective: To compare the effects of six minute walk test and stair climbing test under the hemodynamic and oxygenation in healthy adults. Methods: We conducted a study with healthy subjects above 50 years. The fi rst performed was 6 MWT in quick step with encouragement, in a plan corridor of 30 meters, where the shade was determined the distance walked in 6 minutes, after 6 MWT was performed de SCT with encouragement, on a ladder in shade, consists of 44 steps, with 4 bids and bid by 11 steps, each step measured 16 cm in a total of 7.04 m of height, where the rise time was clocked. Before and after the two tests were measured respiratory rate, pulse, blood pressure and oxygen saturation. Results: We evaluated 21 patients with age 59.6 ± 5.4 years, 5 men and 16 women. The average distance covered on the 6MWT was 496.4 ± 102.2 meters and the average time in SCT 22.6 ± 5.4 seconds. The variables pulse, respiratory rate, systolic blood pressure and Borg scale presented a signifi - cant increase after the tests, however the variables oxygen saturation and diastolic blood pressure did not change signifi cantly. Conclusion: The variables pulse, respiratory rate, systolic blood pressure and Borg scale tests increased after six-minute walk test and stair climbing test but with greater signifi cance after the stair climbing test. Oxygen saturation and diastolic blood pressure did not change signifi cantly after the tests.

The ozone therapy is the therapeutic administration of ozone, which can be: subcutaneous (SC), intramuscular (IM) Intradiscal; intracavitary (pleural and peritoneal spaces); intravaginal, intrauretral, in the bladder; ozonated autohemotherapy. This therapy is being increasingly studied in order to help in some treatments and is being proven to be very effective in most cases, especially in acting on disinfection and healing of extensive wounds. There are over 6000 articles on the medical use of ozone in the literature, but the concentration used varies with each author. Most diseases have a positive response because ozone increases tissue oxygenation and metabolism. Discovered in Germany in the nineteenth century, ozone therapy still needs further study to clarify its mode of action and demonstrate its benefits. The objective of this review is to discuss some of the studies in the literature and try to clarify the main directions and forms of action of ozone therapy in medicine, showing the possibilities of getting good results including in veterinary medicine

O glicerol é um importante subproduto de processos fermentativos. Em algumas bebidas alcoólicas, como vinhos e vodcas contribuem com seu sabor tornando-a aceitável para o consumidor. Com o incentivo na produção de biocombustíveis, a disponibilidade do glicerol deve aumentar, já que é o principal subproduto gerado na produção do Biodiesel. A sua presença em alguns alimentos, pode identificar presença de microrganismos, já que pode ser uma fonte de carbono para eles. Devido às inúmeras utilizações do glicerol para diversos tipos de indústrias, a dosagem do glicerol se torna cada vez mais importante e rotineira. Isso incentiva novas pesquisas de métodos de doseamento. A enzima GK é presente em vários microrganismos e converte o glicerol em glicerol-3-fosfato. Com a utilização da enzima Glicerol -3- fofato desidrogenase, o glicerol - 3 – fosfato é convertido a di-hidroxi-acetona fosfato com a produção de NADH. Este pode ser quantificado através do espectrofotômetro, tornando-se um rápido e eficiente método para doseamento. A levedura recombinante Pichia pastoris foi escolhida pois foi inserida no seu DNA, o Gene GUT1 que expressa a GK em Saccharomyces cerevisiae. Além disso, a expressão enzimática é extracelular, diminuindo etapas no processo de isolamento da enzima GK. O trabalho consistiu em otimizar a produção de GK expressa pela levedura recombinante Pichia pastoris por meio da adição de oxigênio no biorreator de fermentação em escala de 2,5 L. Os resultados do presente estudo indicam o ponto ótimo de oxigenação em fermentador nos parâmetros estabelecidos é de 2,0 lpm tanto para a produção de enzimática quanto para biomassa formada

The objective of the literature review showing their main biological properties involved in the tissue repair process and its therapeutic potential in the prevention , control and treatment of infection in oral surgeries . To carry out this study , a search of the PubMed database . 13 articles that met the inclusion criteria were found . Antimicrobial properties , antiálgicas , anti-inflammatory , imunu - stimulants , oxygenation and neoangiogenesis were attributed to ozone in several studies . And indications such as the treatment of alveolitis , osteomyelitis , osteonecrosis , wound healing in skin and mucosa and antisepsis been suggested. However , many of its effects have not been well understood. The doses and concentrations for their use are not standardized . Studies to establish doses and periods of administration are still needed for increasingly traumatic and biologically effective therapies are found to practice dentistry .
