background: hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. on the other hand, mesenchymal stem cells (mscs) are regarded as potent cells with a property of cartilage regeneration. we aimed to optimize marrow-derived msc chondrogenic culture using a small bioactive molecule referred to as bio. methods: mscs from the ma...

A pyrolysis study on a species of brown algae Saccharina japonica was carried out in a fixed-bed reactor. The yields of bio-oil and bio-char obtained at 450 C were 47 % and 33 %, respectively. The raw S, japonica, ethanol and acid pretreated samples and the resulting pyrolysis products were also characterized with respect to proximate and ultimate analysis, and higher heating value. The crude b...

to study the effects of biological and manure fertilizer on quantity and quality characteristics of roselle (hibiscus sabdariffa l.), an experiment was conducted as split plot based on a randomized complete block design with three replications at the agricultural research center of zabol university, iran during growing season of 2012-2013. treatments included three manure level; 0, 10 and 20 t....

Bio-oil is a dark brown, mobile liquid derived from the thermo-chemical processing of bio-mass. Bio-oils generally contain water and lignin. Lignins are highly-available, well-studied carbohydrate derivative known for their antioxidant properties. For asphalt pavements, oxidation can cause deterioration, a longterm aging process, and eventually result in cracking. Therefore, bio-oil could poten...
