1. The influence of Aloe vera with mesenchymal stem cells from dental pulp on bone regeneration: characterization and treatment of non-critical defects of the tibia in rats
Abstract Objective This study aimed to evaluate the inflammatory effect and bone formation in sterile surgical failures after implantation of a collagen sponge with mesenchymal stem cells from human dental pulp (hDPSCs) and Aloe vera. Material and Methods Rattus norvegicus (n=75) were divided into five experimental groups according to treatment: G1) contr

2. The acute effects of preoperative ozone theraphy on surgical wound healing
ABSTRACT PURPOSE: To investigate the effects of preoperative rectal ozone insufflation on surgical wound healing over the proinflammatory cytokines and histopathological changes. METHODS: Twenty one rabbits were divided into 3 groups. Sham, surgical wound, and ozone applied (6 sessions, every other day 70 µg/mL in 12 mL O2-O3 mixture rectally) surgical wo

3. Fournier?s gangrene - delayed pedicle flap based upon the anterior abdominal wall
Introduction Fournier’s gangrene is a poly-microbial necrotizing fasciitis that involves the perineum and/or external genitalia. Urgent surgical debridement is well recognized as essential acute treatment yet unique challenges arise for plastic surgical reconstruction to obtain a complete functional recovery. This case describes a successful delayed pedi

4. Evasion of immune responses by Trypanosoma cruzi, the etiological agent of Chagas disease
Infection with the protozoan parasite Trypanosoma cruzi leads to Chagas disease, which affects millions of people in Latin America. Infection with T. cruzi cannot be eliminated by the immune system. A better understanding of immune evasion mechanisms is required in order to develop more effective vaccines. During the acute phase, parasites replicate extensiv

5. O uso de células-tronco adultas em modelos experimentais de crises convulsivas. / The use of adult stem cells in experimental models of seizures.
In Brazil, it is estimated that epilepsy affects from 2% of the population, about three million people at different ages and social classes. The use of antiepileptic drugs is the most common form of seizure control, although about 50- 70% of patients with epilepsy are refractory to medication. Because of difficulties in finding effective treatments, it is cr

6. Estudo de mecanismos regulatórios envolvidos na regeneração tecidual em linhagens de camundongos geneticamente selecionados para máxima ou mínima resposta inflamatória aguda. / Study of regulatory mechanisms involved in tissue regeneration in mice selected for high or low acute inflammatory response.
Camundongos foram selecionados geneticamente para alta (AIRmax) ou baixa (AIRmin) resposta inflamatória aguda, sendo utilizados em experimentos de regeneração tecidual. Foi observado que AIRmax apresentam uma regeneração rápida do tecido da orelha em relação aos AIRmin, sugerindo a existência de loci reguladores comuns para ambos fenótipos de infla

7. Avaliação da atividade antimicrobiana, mutagênica e toxicidade aguda de derivados anfifílicos da o-carboximetilquitosana / Evaluation of antimicrobial, mutagenic activity and acute toxicity of amphifilic derivatives of O-carboxymethylchitosan
The chitosan (Ch), a semi-synthetic derivative biopolymer obtained by deacetylation of chitin, has attracted the attention of researchers due to its multiple bioactivities such as hemostasis, antimicrobial, biodegradable, and low oral toxicity. Chitosan inhibits the growth of a wide variety of bacteria and fungi showing a broad spectrum of antimicrobial acti

8. Xenogeneic amniotic membrane associated or not to N-butyl 2-cyanoacrylate in the treatment of corneal perforations. Experimental study in rabbits / Membrana amniótica xenógena, associada ou não ao n-butil 2- cianoacrilato, no tratamento de lesão corneal perfurada. Estudo experimental em coelhos
As pesquisas envolvendo o uso de adesivos cirúrgicos na terapia de lesões penetrantes na córnea são amplas e demonstram sua eficiência na manutenção da integridade ocular e a reação inflamatória causada pelo seu uso. Os vários estudos envolvendo a membrana amniótica denotam suas propriedades favoráveis à epitelização e à sua ação anti-infl

9. Estudo dos mecanismos genéticos e celulares durante a fase inflamatória do processo de regeneração tecidual em animais selecionados geneticamente para a máxima resposta inflamatória aguda homozigotos para os alelos R ou S do gene Slc11a1. / Study of genetic and cellular mechanisms during the inflammatory phase of tissue regeneration process in animals genetically selected for maximum acute inflammatory response homozygous for Slc11a1 R and S alleles.
Homozygous AIRmax and AIRmin sublines for Slc11a1 R and S alleles present distinct regenerative capacity to the ear hole. AIRmaxSS mice exhibited early tissue regeneration compared to AIRmaxRR animals, suggesting that the Slc11a1 S allele promotes regeneration in these animals. AIRmin sublines didnt show regeneration after ear punch. In response to the stimu

10. AUTOGENOUS MONONUCLEAR BONE MARROW CELLS TRANSPLANTATION IN ACUTE IATROGENIC INJURY IN THE REPAIR OF CALCANEOUS TENDON IN DOGS / TRANSPLANTE DE CÉLULAS-TRONCO COM A FRAÇÃO TOTAL DE CÉLULAS MONONUCLEARES AUTÓGENAS DA MEDULA ÓSSEA NA LESÃO IATROGÊNCIA AGUDA DE TENDÃO CALCÂNEO DE CÃES.
Most injuries of the tendons in small animals are linked to trauma and the most important injuries are partial or complete section due to the action of sharp or acute objects or laceration associated with automobile accident leading to a functional disability of the member. The treatments offered are different, but effects such as improving the quality and s

11. Contribution of CD4+ T cells to the early mechanisms of ischemia- reperfusion injury in a mouse model of acute renal failure
Renal ischemia-reperfusion (IR) injury is the major cause of acute renal failure in native and transplanted kidneys. Mononuclear leukocytes have been reported in renal tissue as part of the innate and adaptive responses triggered by IR. We investigated the participation of CD4+ T lymphocytes in the pathogenesis of renal IR injury. Male mice (C57BL/6, 8 to 12

12. O MODELO DESMIELINIZANTE DO BROMETO DE ETÍDIO (BE): ESTUDOS MORFOLÓGICOS EM CAMUNDONGOS C57BL/6 NORMAIS E KNOCKOUT PARA CONEXINA 32 / ETHIDIUM BROMIDE (EB) DEMYELINATING MODEL: MORPHOLOGIC STUDIES IN C57BL/6 NORMAL AND CX 32 KNOCKOUT MICE
Light and ultraestructural changes of central and peripheral nervous system lesions in mice KO for connexin-32 and submitted to the ethidium bromide gliotoxic demyelinating model are described. Their KO condition was tested with PCR and a negative connexin-32 labelling was performed by immunofluorescence. The experimental animals were C57BL/6 normal mice and
