The increasing use of nanomaterials in consumer and industrial products has aroused concerns regarding their fate in biological systems. An effective detection method to evaluate the safety of bio-nanomaterials is therefore very important. Titanium dioxide (TiO(2)), which is manufactured worldwide in large quantities for use in a wide range of applications, including pigment and cosmetic manufa...

PURPOSE To compare the results of focal metallic resurfacing with biologic procedures in patients more than 35 years of age with isolated, full thickness defects of the femoral condyle. METHODS A total of 61 patients met the selection criteria resulting in 30 patients treated with biological procedures, including debridement, microfracture, osteochondral autograft transplantation, osteochondr...

food packaging is inseparable step of the process, storage, distribution and marketing of the product. proper packaging increases the shelf life of food; for this reason that is one of the main characteristics in the food industry. one of the new concepts in food packaging is bio packaging, that is developed to respond to the needs of consumers and food products with higher durability. using ed...

the aim of the present study was to assess the bio-trickling filter startup for the treatment ofwastewater produced by pegah dairy company at psychrophilic condition. the startup time of a bio-tricklingfilter is directly proportional to the concentration of microbial population. abio-trickling column with a height of150 cm was packed with lava rocks with the liquid recirculated through the pack...

The bio-based economy can and should be to the 21 century what the fossil-based economy was to the 20 century. Agriculture will be core to the bio-based economy, providing source materials for commodity items, e.g. liquid fuels and value-added products such as chemicals and materials. For example, a hectare (2.47 acres) of biomass crop converted to 16,800 L (4,450 gallons) of ethanol at a cost ...

The coating of surfaces with bio-functional proteins is a promising strategy for the creation of highly biocompatible medical implants. Bio-functional proteins from the extracellular matrix (ECM) provide effective surface functions for controlling cellular behavior. We have previously screened bio-functional tripeptides for feasibility of mass production with the aim of identifying those that a...

Research for new biocompatible and easily implantable materials continously proposes new molecules and new substances with biological, chemical and physical characteristics more and more adapted to aesthetic and reconstructive surgery. Bio-Alcamid (Polymekon, Italy) is a non reabsorbable polymeric material composed of alkylimide-amide groups. This cosmetic agent has been used for the treatment ...
