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 ...

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...

Gene targeting studies revealed that Dicer1 is required for murine embryogenesis.In this issue of Blood, Alemdehy and colleagues examine deletion of Dicer1 in myeloid progenitor cells using a conditional Cebpa-Cre allele. They show that deletion of Dicer1 is required for viability and that Dicer1 regulates steps of neutrophil maturation.

This study aimed to the effect of chemical preservatives on dehydrated diced radish, as well their taste, nutritional value and shelf life final product. Before dehydration turnip were treated with different concentrations viz. The eight samples added T1 = 0.1% potassium metabisulphite, T2 sodium benzoate, T3 sorbate, T4 0.05% metabisulphite + T5 T6 benzoate sorbateT7 0.025% Benzoate T0 no pres...
