Ischemic perconditioning on mesenteric ischemia/reperfusion injury in rats
Cavalcante,Lainy Carollyne da Costa; Rodrigues,Giannini Medeiros; Ribeiro Júnior,Rubens Fernando Gonçalves; Monteiro,Andrew MoraesABSTRACT Purpose: To evaluate if the perconditioning affects the antioxidant capacity in mesenteric ischemia and reperfusion injury. Methods: Twenty-one Wistar rats were assigned into three groups, as follows: Sham, IR and rPER. The animals were subjected to mesenteric ischemia for 30 min. rPER consisted of three cycles of 5-min hindlimb ischemia followed by 5 min hindlimb perfusion at the same time to mesenter...
Remote ischemic conditioning enhances heart and brain antioxidant defense
Costa,Felipe Lobato da Silva; Teixeira,Renan Kleber Costa; Yamaki,Vitor Nagai; Valente,André Lopes; Percário,Sandro; Brito,Marcus Vinicius HenriquesAbstract Background Ischemia-reperfusion injury contributes to morbidity after revascularization procedures. Along with early reperfusion, tissue conditioning by alternating intervals of brief ischemia-reperfusion episodes is considered the best approach to limit tissue damage. Remote ischemic conditioning is conducted remotely, in tissues other than those under ischemia. Despite this, remote ischemic condition...
The role of adiponectin in ischemia-reperfusion syndrome: a literature review
Carballo,Mariela Carolina Santos; Pinto,Luís Claudio Santos; Brito,Marcus Vinicius HenriquesABSTRACT Adiponectin, among other diverse adipokines, is produced in greater quantity and has an effect on the adipose tissue and other tissues in the body. Adiponectin plays three main roles: regulatory metabolic and sensitizing function of insulin in the liver and muscles; it acts as an anti-inflammatory cytokine and in vascular protection, besides important cardiac protection in the presence of ischemia-repe...

Brito,Marcus Vinicius Henriques; Yasojima,Edson Yuzur; Percário,Sandro; Ribeiro Júnior,Rubens Fernando Gonçalves; Cavalcante,Lainy Carollyne da CostaAbstract Purpose: To evaluate the effects of hypertonic saline solution associated to remote ischemic perconditioning in renal ischemia/reperfusion injury in rats. Methods: Twenty five male rats (Wistar) underwent right nephrectomy and were distributed into five groups: Sham group (S); Ischemia/Reperfusion group (I/R) with 30 minutes of renal ischemia; Remote ischemic perconditioning group (Per) with three cycl...
Influence of remote ischemic conditioning and tramadol hydrochloride on oxidati...
Oliveira,Rita de Cássia Silva de; Brito,Marcus Vinicius Henriques; Ribeiro Júnior,Rubens Fernando Gonçalves; Oliveira,Leonam Oliver DurvalAbstract Purpose: To evaluate the effects of tramadol hydrochloride associated to remote ischemic perconditioning on oxidative stress. Methods: Twenty five male rats (Wistar) underwent right nephrectomy and were distributed into five groups: Sham group (S); Ischemia/Reperfusion group (I/R) with 30 minutes of renal ischemia; Remote ischemic perconditioning group (Per) with three cycles of 10 minutes of I/R perfo...
Perconditioning combined with postconditioning on kidney ischemia and reperfusion
Costa,Felipe Lobato da Silva; Yamaki,Vitor Nagai; Teixeira,Renan Kleber Costa; Feijó,Daniel Haber; Valente,André Lopes; Carvalho,Luan Teles Ferreira deAbstract Purpose: To evaluate if combination of perconditioning and postconditioning provides improved renal protection compared to perconditioning alone in a model of renal reperfusion injury. Methods: Thirty rats were assigned into 6 groups: normality; sham; ischemia and reperfusion; postconditioning; perconditioning; perconditioning + postconditioning. Animals were subjected to right nephrectomy and left ren...
Perconditioning associated to hypertonic saline solution on liver function impr...
Ribeiro Júnior,Rubens Fernando Gonçalves; Couteiro,Rodrigo Paracampo; Monteiro,Andrew Moraes; Rodrigues,Ivone Aline da SilvaAbstract Purpose: To evaluate the effects of hypertonic saline solution associated to remote ischemic perconditioning in liver ischemia/reperfusion injury in rats. Methods: 25 male rats (Wistar) were distributed into five groups: Sham group (S); Ischemia/Reperfusion group (I/R) with 30 minutes of liver ischemia; Remote ischemic perconditioning group (Per) with three cycles of 10 minutes of I/R performed during ...
Development of a laparoscopic training model using a smartphone
Oti,André Takashi; Galvão,Lucas Nascimento; Pessoa,Thyago Cezar Prado; Rocha,Camylla Rodrigues de Oliveira; Monteiro,Andrew MoraesABSTRACT Objective: to develop a model of training in video-surgery, of low cost and that uses a smartphone as an image-generating source. Methods: We developed a 38cm high, 40cm wide, 40cm long hexagonal-shaped training box, with a front opening of 12x8 cm for coupling the smartphone. The internal illumination is made with LED lamps and for the support of the smartphone, we used a selfie stick, fixed in the up...

Brito,Marcus Vinicius Henriques; Botelho,Nara Macedo; Yasojima,Edson Yuzur; Teixeira,Renan Kleber Costa; Yamaki,Vitor Nagai; Feijó,Daniel HaberABSTRACT PURPOSE: To verify the publication rate of the abstracts presented at the XII Brazilian Congress of Experimental Surgery. METHODS: We performed a cross-sectional study that evaluated if the abstracts accepted for presentation at the XII Brazilian Congress of Experimental Surgery were published in periodics. The information was acquired using the Scielo, Medline / Pubmed, LILACS and Google Scholar datab...
Stem cells from adipose tissue improve the time of wound healing in rats
Ohashi,Camila Melo; Caldeira,Fabio Alves Morikawa; Feitosa-Junior,Denilson José Silva; Valente,André Lopes; Dutra,Paulo Roberto WitterABSTRACT PURPOSE: To evaluate the Adipose Stem Cells (ACS) therapy efficacy on the time and quality of wound healing process in rats. METHODS: Nine male Wistar rats were randomly distributed into three groups I) 7 days of healing; II) 14 days of healing; III) 21 days of healing. Four incisions were made on the dorsal surface of each rat and then treated with intralesional ACS, meloxicam, and no treatment and AC...
