Provedor de dados: 74
Autores: Baruffi,Marcelo Razera; Barbieri-Neto,J.; Pina-Neto,João Monteiro; Suerzut,C.E.; Casartelli,Cacilda.
Cytogenetic analyses were performed on a bone giant cell reparative granuloma (GCRG) and on three bone giant cell tumors (GCT). The present GCRG case is the second to be described cytogenetically. A modal chromosome number of 46 was observed in all samples. Clonal chromosome abnormalities were detected in all cases. The numerical alterations most frequently observed involved the loss of chromosomes 17 and 18. Among the structural anomalies observed, there was preferential involvement of chromosomes 6 and 10. Three GCT cases presented del(10)(p13) and two cases presented del(6)(q25) (1 GCRG and 1 GCT). These breakpoints mapped on 10p and 6q may harbour genes of importance in the development of bone giant cell tumors.

Provedor de dados: 5
Autores: Noel, Danièle.
Hemic proliferative disease in the bay mussel, Mytilus edulis, has been studied following mortalities in Washington State (USA). The disease has been reproduced in the labortory. The establishment of this experimental model led to study tumoral characteristics of the atypic hemocytes : ultrastrure, in vitro cultivation, transplantation. The infectious etiology of this tumor has been verified. It has been hypothesized to result from a viral infection since retrovirus-like particules have been observed following induction by bromodeoxyuridine. Specific monoclonal antibodies against atypic hemocytes have been obtained and characcterized

Effect of Curcuma zedoaria crude extract against tumor progression and immunomodulation
Provedor de dados: 80
Autores: Carvalho,FR; Vassão,RC; Nicoletti,MA; Maria,DA.
The aim of the present work was to study the effect of the crude extract of Curcuma zedoaria on peripheral blood cells and tumor progression in C57Bl/6J mice injected with B16F10 murine melanoma cells. The intraperitoneal therapy showed a significant increase in total white and red blood cell counts, a decrease in peritoneal cell number and tumor volume reduction, whereas the oral administration revealed a noteworthy augmentation only in total leukocyte count. These results contribute to evaluate the importance of alternative treatments that employ phytotherapic compounds against tumor progression and its possible immunomodulation.

Tumor cytotoxicity of leucurolysin-B, a P-III snake venom metalloproteinase from Bothrops leucurus
Provedor de dados: 80
Autores: Gabriel,LM; Sanchez,EF; Silva,SG; Santos,RG.
Although it has been demonstrated that venoms and toxins from some snakes are able to influence the growth of tumor cells, few antitumoral compounds from Bothrops leucurus venom have been characterized. Leucurolysin-B (leuc-B) is a metalloproteinase class P-III isolated from B. leucurus which possesses an ECD-disintegrin domain. Both ECD-disentegrin and RGD-disintegrin are able to bind to cell surface integrins and inhibit their adherence to their natural ligands. In the present study, the potential efficacy and the cytotoxic effects of leuc-B on glioblastoma, breast cancer and melanoma cell lines were analyzed. The effect of leuc-B on cancer cell survival was evaluated and its 50% inhibitory concentration (IC50) was determined. Morphological alterations...

Soft tissue sarcomas in dogs: does surgical resection heal?
Provedor de dados: 195
Autores: Castro, Patrícia Ferreira de; Campos, Andressa Gianotti; Matera, Julia Maria.
Soft tissue sarcomas (STS), a heterogeneous group of different tumors of mesenchymal origin, are described as pseudo-encapsulated masses with poor defined margins that present high rates of local recurrence compared to the low to moderate metastatic potential. They can occur both in humans and animals, and in dogs they comprise approximately 15% of all skin and subcutaneous tumors. Due to its invasive behavior, surgery is the main treatment applied for these tumors in dogs, and it can be combined to radiotherapy after the incomplete resection because the role of chemotherapy is still very poorly understood in this subject.

Autores: Ferreira,M.G.P.A.; Antunes,A.V.; Pascoli,A.L.; Nazaret,T.L.; Gering,A.P.; Reis Filho,N.P.; Costa,M.T.; Nardi,A.B.
ABSTRACT Neuropathic pain occurs when there is a lesion or a dysfunction of the nervous system. Humans and veterinary patients may develop neuropathic pain, but in veterinary it is not often reported probably because of its mistaken diagnosis. A canine patient was admitted to the Veterinary Hospital of UNESP-Jaboticabal-SP, Brazil with a nodule on the left thoracic limb. The nodule was surgically removed, and histopathological analysis demonstrated the tumor was a soft tissue sarcoma (STS) and the margins were not clean. Based on the patient’s health condition and the lack of suitable equipment, the next procedure was limb amputation. The patient received analgesic medication in the post-surgery period; nevertheless, clinical signs of neuropathic pain were...

Celecoxib decreases growth and angiogenesis and promotes apoptosis in a tumor cell line resistant to chemotherapy
Provedor de dados: 48
Autores: Rosas,Carlos; Sinning,Mariana; Ferreira,Arturo; Fuenzalida,Marcela; Lemus,David.
BACKGROUND: During the last few years it has been shown in several laboratories that Celecoxib (Cx), a non-steroidal anti-inflammatory agent (NSAID) normally used for pain and arthritis, mediates antitumor and antiangiogenic effects. However, the effects of this drug on a tumor cell line resistant to chemotherapeutical drugs used in cancer have not been described. Herein we evaluate the angiogenic and antitumor effects of Cx in the development of a drug-resistant mammary adenocarcinoma tumor (TA3-MTXR). RESULTS: Cx reduces angiogenesis in the chick embryonic chorioallantoic membrane assay (CAM), inhibits the growth and microvascular density of the murine TA3-MTXR tumor, reduces microvascular density of tumor metastases, promotes apoptosis and reduces...

Angiogenesis, the development of new blood vessels from the existing vascular network, may result as a consequence of the increase or decrease of proangiogenic or antiangiogenic factors, respectively. The tumor itself could up-regulate the production of angiogenic factors. Recently, we established that the steroidal drug betamethasone in low concentration inhibit the neovascularization promoted by TA3 Ts on CAM of chick embryos. We describe here the effects of the non-steroidal drug ketoprofen, alone or in association with betamethasone, on the angiogenesis promoted by TA3 Ts on CAM. The main finding reported here is that the formation of new blood vessels is strongly inhibited by low concentrations of ketoprofen. The association of both drugs produced a...

High resolution proton nuclear magnetic resonance spectroscopy (¹H MRS) can be used to detect biochemical changes in vitro caused by distinct pathologies. It can reveal distinct metabolic profiles of brain tumors although the accurate analysis and classification of different spectra remains a challenge. In this study, the pattern recognition method partial least squares discriminant analysis (PLS-DA) was used to classify 11.7 T ¹H MRS spectra of brain tissue extracts from patients with brain tumors into four classes (high-grade neuroglial, low-grade neuroglial, non-neuroglial, and metastasis) and a group of control brain tissue. PLS-DA revealed 9 metabolites as the most important in group differentiation: γ-aminobutyric acid, acetoacetate, alanine,...

ABSTRACT: Renal cell carcinoma, especially with extensive involvement of peritoneal cavity, is rarely described in horses. This study described a case of renal cell carcinoma in an 8-year-old mare, which presented with an enlargement in the left flank, decreased appetite and straining to defecate. Clinically, a tumor in the left retroperitoneal space was detected by rectal examination and ultrasonography. The animal died after one month of clinical evolution. At necropsy, the left kidney was completely effaced by a 50cm in diameter, irregular, round, lobulated cystic mass with necro-hemorrhagic areas. Within the peritoneal cavity, there was severe hemoperitoneum and numerous sessile and pedunculated masses ranging from 2.0 to 15.0cm diameter that were...

Laryngeal and tracheal tumors are rare in pets; some piece of information on their disease behavior, therapy and evolution are limited. Neoplasms in this area are a diagnostic challenge. In many cases, they can be biopsied and excised using endoscopic instruments, but there is no report of this in canines. The goal of this study is to report a successful case of a laryngeal neoplasm removal through endoscopy. A head and neck radiogram revealed a mass in the laryngeal lumen protruding into the trachea. The patient then underwent an endoscopy to confirm the radiographic diagnosis and to surgically remove the tumor. The histopathological diagnosis was poorly differentiated carcinoma. The most appropriate treatment for laryngeal tumors is the resection of the...
