1. Decellularized Bovine Articular Cartilage Matrix Reinforced by Carboxylated-SWCNT for Tissue Engineering Application
ABSTRACT Nanotubes with their unique properties have diversified mechanical and biological applications. Due to similarity of dimensions with extracellular matrix (ECM) elements, these materials are used in designing scaffolds. In this research, Carboxylated Single-Wall Carbon Nanotubes in optimization of decellularized scaffold of bovine articular cartilage

2. Influência da indometacina no processo regenerativo da nadadeira caudal de teleósteo: análise morfométrica e ultraestrutural
Quando parcialmente amputadas ou severamente injuriadas, as nadadeiras de teleósteos sofrem um processo de regeneração chamado de regeneração epimórfica, caracterizado pelas seguintes fases: formação de uma capa epidermal multiestratificada, desorganização e migração distal de células mesenquimais multipotentes, proliferação dessas células pa

3. Estudo histológico da dinâmica da regeneração da epiderme da nadadeira caudal da carpa (Cyprinus carpio Linnaeus, 1758)
As nadadeiras dos teleósteos, quando parcialmente amputadas, sofrem um processo de regeneração chamado de regeneração epimórfica, caracterizado pelas seguintes fases: cicatrização, a partir da formação de uma capa epidermal multiestratificada, formação de uma massa de células mesenquimais multipotentes chamada blastema, diferenciação dessas c�

4. 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

5. Analise histoquimica, ultra-estrutural e morfometrica do efeito de drogas anti-inflamatorias não esteroides (naproxeno e indometacina) sob a regeneração da nadadeira caudal de teleosteo, Cyprinus carpio (carpa) / Histochemical, ultra-structural and morphometric analysis of the effect of nonsteroidal anti-inflammatory drugs (naproxen and indomethacin) under the tail fin regeneration of teleostm Cyprinus carpio (carp)
The fins of teleosts, when partially amputated, they pass for a quick regenerative process called epimorphic regeneration, characterized by the formation of a mass of undifferentiated cells, by the differentiation of these cells, by the synthesis and the deposition of the extracellular matrix and morphological restoration. The regeneration of the fin is extr

6. Comparative karyotype analysis in diploid and triploid Dolichoplana carvalhoi (Tricladida, Terricola, Rhynchodemidae) from Brazil
In this work, we present cytogenetic data for the land planarian Dolichoplana carvalhoi. Two different karyotypes, one diploid (2n = 2x = 14 chromosomes) and one triploid (2n = 3x = 21 chromosomes), corresponding to two morphological body patterns, are described. Chromosomes from regenerating blastema were studied after routine Giemsa staining and CBG bandin

7. Carcinoma renal dos ductos de Bellini
Two types primary epithelial tumours of the kidney have been distinguished, such as renal cell carcinoma (hypernephroma or Grawitz) deriving from proximal tubules and carcinoma arising in the urothelium of the kidney's collecting system. Mancilla-Jimenez e cols were the first to describe in 1976 an atypical papillary carcinoma of the kidney deriving from col

8. Proteína p53 em nefroblastomas
A imunoexpressão do antígeno p53 foi estudada em 35 pacientes com idade média de 38± 29 meses. Todos foram tratados com nefrectomia e quimioterapia, em 17 se associou também a radioterapia. O tempo médio de seguimento foi de 69± 66 meses. Em 5 deles a histologia era defavorável. Em 10 casos (28,5%) a marcação foi positiva, com ordem crescente de po

9. Antígeno MIB-1 em nefroblastomas
Foram estudados 35 pacientes tratados com nefrectomia radical e quimioterapia, em 17 (48,5%) dos quais se associou também a radioterapia. A idade média dos pacientes foi de 38± 29 meses e o tempo de seguimento pós-operatório de 69± 66 meses. Óbito pela neoplasia ocorreu em 5 pacientes, todos com histologia favorável. As peças conservadas em formol o

10. Heat-shock protein 60 is required for blastema formation and maintenance during regeneration
Zebrafish fin regeneration requires the formation and maintenance of blastema cells. Blastema cells are not derived from stem cells but behave as such, because they are slow-cycling and are thought to provide rapidly proliferating daughter cells that drive regenerative outgrowth. The molecular basis of blastema formation is not understood. Here, we show that

11. The mutant axolotl Short toes exhibits impaired limb regeneration and abnormal basement membrane formation.
The mutant axolotl Short toes develops with abnormal kidneys, Mullerian ducts, and limbs and provides one of the few experimental systems for developmental studies in amphibia. The present paper describes another deviation from this animal's normal physiology, which is very characteristic of the wild type: amputated limbs of Short toes fail to regenerate. A

12. Temperature-Sensitive Mutations That Cause Stage-Specific Defects in Zebrafish Fin Regeneration
When amputated, the fins of adult zebrafish rapidly regenerate the missing tissue. Fin regeneration proceeds through several stages, including wound healing, establishment of the wound epithelium, recruitment of the blastema from mesenchymal cells underlying the wound epithelium, and differentiation and outgrowth of the regenerate. We screened for temperatur
