Avaliação ultra-sonográfica e pelo Doppler colorido do carcinoma de células transicionais da bexiga em cães
Provedor de dados: 45
Autores: Froes,T.R.; Iwasaki,M.; Campos,A.G.; Torres,L.N.; Dagli,M.L.Z.
Estudaram-se os aspectos ultra-sonográficos das lesões sugestivas de carcinoma de células transicionais (CCT), investigou-se a contribuição do mapeamento Doppler colorido e de amplitude no diagnóstico das lesões sugestivas de CCT e verificou-se a acurácia do método de biópsia ecodirigida por sucção traumática via sondagem uretral na coleta de material para confirmação diagnóstica CCT da bexiga. Para tal, foram selecionados nove cães que atendiam aos critérios de inclusão determinados. Destes, sete apresentavam CCT. A ultra-sonografia permitiu a detecção de massas exofílicas com características vegetantes em cinco cães, e de lesões infiltrativas na parede vesical estendendo-se para a uretra em dois. Pelo exame com Doppler colorido e de amplitude,...

Modelo de suplementação nutricional com fatores hepatotróficos aumenta proliferação celular em fígado de ratos sadios
Provedor de dados: 45
Autores: Aloia,T.P.A.; Cogliati,B.; Guerra,R.R.; Parra,O.M.; Dagli,M.L.Z.; Hernandez-Blazquez,F.J.
Foram avaliados dois protocolos de administração, em ratos sadios, de uma solução de fatores hepatotróficos (FH), composta por aminoácidos, vitaminas, sais minerais, glicose, insulina, glucagon e triiodotironina (T3). A solução foi administrada durante 10 dias, 40mg/kg/dia, i.p., em duas, grupo 2xFH (n=15), ou três doses, grupo 3xFH (n=15), diárias. Foram observados os efeitos na proliferação celular dos hepatócitos, na angiogênese e na matriz extracelular hepática, assim como as possíveis reações adversas. Os animais dos grupos 2xFH e 3xFH apresentaram aumento da massa hepática de 30,1% e 22,5%, respectivamente, em relação ao grupo-controle (CT; n=15). O índice de proliferação hepatocelular foi maior nos grupos 2xFH (1,4%) e 3xFH (1,2%) em relação ao...

Primary intraocular chondrosarcoma in a dog
Provedor de dados: 45
Autores: Perlmann,E.; Morales,A.; Góes,A.C.A.; Dagli,M.L.Z.; Barros,P.S.M.
A five-year-old male Cocker Spaniel was presented for evaluation of the right eye due to discomfort, abundant purulent discharge and progressive enlargement of the eyeball. The owner revealed that the right eye has appeared to be inflamed and smaller then the left eye for years. Ophthalmic examination revealed corneal perforation, buphthalmia and conjuctival hyperemia. Enucleating was performed due to signs of endophthalmitis and ocular discomfort. Histopathology revealed a multilobulated proliferation of chondrocytes producing hyaline cartilage with occasional pleomorphism and binucleate cells. A diagnosis of primary intraocular chondrosarcoma was done.

Modulation of extracellular matrix by nutritional hepatotrophic factors in thioacetamide-induced liver cirrhosis in the rat
Provedor de dados: 56
Autores: Guerra,R.R.; Trotta,M.R.; Parra,O.M.; Avanzo,J.L.; Bateman,A.; Aloia,T.P.A.; Dagli,M.L.Z.; Hernandez-Blazquez,F.J.
Nutritional substances associated to some hormones enhance liver regeneration when injected intraperitoneally, being denominated hepatotrophic factors (HF). Here we verified if a solution of HF (glucose, vitamins, salts, amino acids, glucagon, insulin, and triiodothyronine) can revert liver cirrhosis and how some extracellular matrices are affected. Cirrhosis was induced for 14 weeks in 45 female Wistar rats (200 mg) by intraperitoneal injections of thioacetamide (200 mg/kg). Twenty-five rats received intraperitoneal HF twice a day for 10 days (40 mL·kg-1·day-1) and 20 rats received physiological saline. Fifteen rats were used as control. The HF applied to cirrhotic rats significantly: a) reduced the relative mRNA expression of the genes: Col-α1 (-53%),...

Efficacy of the dietary histone deacetylase inhibitor butyrate alone or in combination with vitamin A against proliferation of MCF-7 human breast cancer cells
Provedor de dados: 56
Autores: Andrade,F.O.; Nagamine,M.K.; Conti,A. De; Chaible,L.M.; Fontelles,C.C.; Jordão Junior,A.A.; Vannucchi,H.; Dagli,M.L.Z.; Bassoli,B.K.; Moreno,F.S.; Ong,T.P.
The combined treatment with histone deacetylase inhibitors (HDACi) and retinoids has been suggested as a potential epigenetic strategy for the control of cancer. In the present study, we investigated the effects of treatment with butyrate, a dietary HDACi, combined with vitamin A on MCF-7 human breast cancer cells. Cell proliferation was evaluated by the crystal violet staining method. MCF-7 cells were plated at 5 x 10(4) cells/mL and treated with butyrate (1 mM) alone or combined with vitamin A (10 µM) for 24 to 120 h. Cell proliferation inhibition was 34, 10 and 46% following treatment with butyrate, vitamin A and their combination, respectively, suggesting that vitamin A potentiated the inhibitory activities of butyrate. Furthermore, exposure to this...

Expression of NR1I3 in mouse lung tumors induced by the tobacco-specific nitrosamine 4-(methylnitrosamino)-4-(3-pyridyl)-1-butanone
Provedor de dados: 56
Autores: Fukumasu,H.; Cordeiro,Y.G.; Rochetti,A.L.; Barra,C.N.; Sámora,T.S.; Strefezzi,R.F.; Dagli,M.L.Z.
Nuclear receptor subfamily 1, group I, member 3 (NR1I3) is reported to be a possible novel therapeutic target for some cancers, including lung, brain and hematopoietic tumors. Here, we characterized expression of NR1I3 in a mouse model of lung carcinogenesis induced by 4-(methylnitrosamino)-4-(3-pyridyl)-1-butanone (NNK), the most potent tobacco carcinogen. Lung tumors were collected from mice treated with NNK (400 mg/kg) and euthanized after 52 weeks. Benign and malignant lesions were formalin-fixed and paraffin-embedded for histology and immunohistochemistry, with samples snap-frozen for mRNA analysis. Immunohistochemically, we found that most macrophages and type I and II pneumocytes expressed NR1I3, whereas fibroblasts and endothelial cells were...

Skin morphology of the mutant hairless USP mouse
Provedor de dados: 56
Autores: Massironi,S.M.G.; Giacóia,M.R.; Maiorka,P.C.; Kipnis,T.L.; Dagli,M.L.Z.
The morphology of the skin of the mutant hairless USP mouse was studied by histological, histochemical and immunohistochemical methods and compared to the skin of BALB/c mice. Representative sections of the dorsal skin from mice of both strains aged 18 days, and 1, 3, 6, and 8 months were studied. Sections stained with hematoxylin and eosin showed cystic formations called utricles and dermal cysts in the dermis that increased in size and number during growth. Skin thickness increased significantly at 8 months. Sections stained with picrosirius and examined with polarized light, displayed different colors, suggesting different thicknesses of dermal collagen fibers (probably types I and III). Weigert, Verhoeff and resorcin-fuchsin stains revealed fibers of...

Paullinia cupana Mart var. sorbilis, guaraná, reduces cell proliferation and increases apoptosis of B16/F10 melanoma lung metastases in mice
Provedor de dados: 56
Autores: Fukumasu,H.; Avanzo,J.L.; Nagamine,M.K.; Barbuto,J.A.; Rao,K.V.; Dagli,M.L.Z.
We showed that guaraná (Paullinia cupana Mart var. sorbilis) had a chemopreventive effect on mouse hepatocarcinogenesis and reduced diethylnitrosamine-induced DNA damage. In the present experiment, we evaluated the effects of guaraná in an experimental metastasis model. Cultured B16/F10 melanoma cells (5 x 10(5) cells/animal) were injected into the tail vein of mice on the 7th day of guaraná treatment (2.0 mg P. cupana/g body weight, per gavage) and the animals were treated with guaraná daily up to 14 days until euthanasia (total treatment time: 21 days). Lung sections were obtained for morphometric analysis, apoptotic bodies were counted to calculate the apoptotic index and proliferating cell nuclear antigen-positive cells were counted to determine the...
