Concerns regarding the depletion of the world's reserves of oil and global climate change have promoted an intensification of research and development toward the production of biofuels and other alternative sources of energy during the last years. There is currently much interest in developing the technology for third-generation biofuels from microalgal biomass mainly because of its potential f...

Bacteria such as Escherichia coli are frequently grown to high density to produce biomolecules for study in the laboratory. To achieve this, cells can be incubated in extremely rich media that increase overall cell yield. In these various media, bacteria may have different metabolic profiles, leading to changes in the amounts of toxic metabolites produced. We have previously shown that stresses...

Platelet-rich plasma (PRP) may have the potential to enhance articular cartilage regeneration through release of growth factors including transforming growth factor isoforms. The purpose of this study was to investigate the potential for PRP to stimulate chondrogenic differentiation in three-dimensional PRP hydrogel constructs. Allogenic PRP was prepared using a double centrifugation protocol w...

objectives effect of using autologous platelet-rich plasma (prp) on pain reduction in patients with pilonidal abscess, subjected to extensive surgical removal tissue, was investigated through a clinical trial. patients and methods the trial was conducted on two groups from the center for surgical research at mashhad university of medical sciences located at ghaem hospital in mashhad city in 201...

objective: at present, growth factor-containing products such as enamel matrix derivatives, recombinant bone morphogenetic protein (rh-bmp), recombinant platelet derived growth factor and platelet rich plasma (prp) have gained increasing attention. prp is an autologous source of platelet growth factors used to enhance healing of soft and hard tissues. prp has gained popularity due to its autolo...

introduction: umbilical cord blood is a rich source of hematopoietic cells and can be used in the clinical setting for hematopoietic cell transplantation in graft versus host disease (gvhd). a number of different drugs have been used as prophylaxis against gvhd including corticosteroids, cyclosporine a (cy a) and fk506. in this study, the in vitro effects of fk506 on cord blood mononuclear cell...

With the introduction of national strategies such as Healthy China 2030, big health industry has ushered in new development opportunities and now become one economic growth points China. Relying on its rich selenium resources, Shiquan County, Ankang, Shaanxi grown many selenium-enriched products, developed resources for care, culture tourism, built a relatively complete industry. In era industr...

the clinical use of prp therapy in the practical setting of orthopaedic fields is increasing partly because of the accessibility of devices that are used in outpatient preparation and delivery. another reason is the strong advertisement of prp procedures as the ultimate treatment and novel technology for knee problems by a few orthopaedic surgeons based on claims of abundant scientific evidence...

background: osteoarthritis is a disabling musculoskeletal disease with no definite treatment. this study compared the effect of platelet-rich plasma (prp) and transcutaneous electrical nerve stimulation (tens) plus exercise in the treatment of patients with knee joint osteoarthritis.   methods : 54 eligible patients with knee osteoarthritis were randomly allocated into two groups. (irct20121106...
