background: this work aimed to show and compare the degradation time of some of cartilage extracellular matrix components using an in vitro model for cartilage degradation induced by interleukin-1 alpha. it is known that elucidation of molecular events under interleukin-1 alpha induction of bovine nasal cartilage could obtain useful data to understand more about involving mechanisms for tissue ...

BACKGROUND According to statistics of American Society of Plastic Surgeons, cosmetic rhinoplasty was the second most frequently performed cosmetic surgery. This study shares the experiences with component rhinoplasty. METHODS From 2004 to 2010, all patients underwent aesthetic nasal surgery were enrolled. The patients requiring only correction of septal deviation and those presenting with cle...

cartilage hair hypoplasia (chh), is a rare cause of metaphyseal chondrodysplasia and short stature. other features included hair abnormality, immunodeficiency, anemia, gastrointestinal disorders (hirschsprung disease, celiac, …) and increased risk of cancer. the disease is an autosomal recessive disorder and previously has not been reported in iran. we report a 9-year-old boy diagnosed as carti...

cartilage is an avascular, aneural, and alymphatic connective tissue with a limited capacity caused by low mitotic activity of its resident cells, chondrocytes. natural repair of full thickness cartilage defects usually leads to the formation of fibrocartilage with lower function and mechanical force compared with the original hyaline cartilage and further deterioration can occur. tissue engine...

the aim of the present study was to develop a tissue-engineering approach through alginate gel molding to mimic cartilage tissue in a three-dimensional culture system. the perfusion biomimetic bioreactor was designed to mimic natural joint. the shear stresses exerting on the bioreactor chamber were calculated by computational fluid dynamic (cfd). several alginate/bovine chondrocyte constructs w...

background:several investigations showed cartilaginouscells in fibrous tissue of the free part of the penis in one humpedcamel. objectives: the aim of this study was accurate assessmentof existence of cartilaginous cells in penis shaft of onehumpedcamel. methods: six camel penises from maturedcamels more than 3 years-old were collected from an abattoir.different specimens were prepared from eac...

conclusions we feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems. introduction a sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. tibial tubercle sl...

In this study we examined enhancement effects of Artemisinin plus Glucantime and shark cartilage extract, on promastigotes and amastigotes of L.infantum in in vitro condition.The toxicity of artemisinin, glucantime and shark cartilage extract on the L. infantum promastigotes and amastigote-infected macrophages was evaluated using MTT assay. The role of these drugs in inducing apoptosis in proma...

Objective- To evaluate the biological compatibility of differentiated stem cells embedded in poly-vinyl-alcohol (PVA) scaffolds for repair of distal femoral cartilage defect.   Design- Experimental in vivo study. Animals- Twelve adult male New Zealand white rabbits were used which were divided into two groups (I, II) six rabbits each.   Procedures- Mesenchymal stem cells were isolated from h...

Na pandemia COVID-19, iniciativas envolvendo estratégias de agricultura urbana foram implementadas ou expandidas, sistemas abastecimento e transformação dos territórios urbanos são tópicos frequentes pesquisa reflexão atuais. A cidade Conchal/SP traz exemplos práticas cidades saudáveis, incorporadas ao seu território, gestão pública planejamento urbano suas experiências podem ser estudadas para...
