| ABSTRACT: Progressive deterioration and loss of articular cartilage are the final degenerative events common to osteoarthritis (OA). Reactive oxygen species (ROS) play an important role in this chondrocyte catabolic activity, leading to cell death and matrix components breakdown. Intra-articular corticosteroid injections such as triamcinolone acetonide have been used to control pain and inflammation associated with OA. New treatments for OA, platelet-rich plasma and pentosan polysulphate sodium have also been used and further investigations are necessary to determine their safety in joint cells. In this in vitro study, the use of these three substances (triamcinolone acetonide, platelet-rich plasma, and pentosan polysulphate sodium) in healthy... |

| ABSTRACT: In healthy cartilage, chondrocytes maintain an expression of collagens and proteoglycans and are sensitive to growth factors and cytokines that either enhance or reduce type II collagen synthesis. In osteoarthritis, pro-inflammatory cytokines, such as IL-6, induce overexpression of metalloproteinases (MMP) and decreasing synthesis of aggrecan. Use of chondroprotectors agents, such as Platelet-Rich Plasma (PRP) and triamcinolone (TA) are alternatives to reduce the progression of joint damage. In this study, we used chondrocytes extracted from metacarpophalangeal joints of healthy horses as the experimental model. Cells were treated in vitro with PRP or TA. No differences were observed between these treatments in comparison to the control group... |

| The species Amblyomma longirostre Koch, 1844 is poorly known in the state of Rio Grande do Sul. Usually the adult stage could be found on Sphigurus spp. and the immatures on birds (Passeriformes). Although A. longirostre is distributed in the Neotropical region, from Panama to Uruguay, it also occurs in Central America and the United States. The aim of this study was to report that Ramphastos dicolorus Linnaeus 1766 is a new host record for this tick species. |

| Com o objetivo de definir a prevalência de alterações ósseas no tarso, foram examinados radiograficamente 77 potros da raça Crioula, com até 26 meses de idade e a relação das lesões com parâmetros biométricos e de manejo. Os animais foram divididos em dois grupos por idade: G1, incluindo potros de nove a 18 meses (34/77); e G2, com animais de 19 a 26 meses (43/77). Os animais também foram divididos pelo tempo de preparo para exposição morfológica em GC, grupo controle (29/77), os animais sem preparo para exposição; e GI, grupo incentivo (48/77), animais com preparo médio de 4,55 meses, e foram separados por sexo em machos (46/77) e fêmeas (31/77). Os dados foram coletados em 24 propriedades de criação ou centros de treinamento/preparo do estado do Rio... |
