It has been reported that equilibrium ionization is achieved in about 20 microseconds behind oxy-hydrogen and oxy-acetylene detonation waves (1), and that the electrical conductivity of the gas behind the detonations is of the order of 10-) mhos/cm. To obtain magnetohydrodynamic interaction with reasonable magnetic fieldsconductivities of the order of 10 mhos/cm are required of combustion gases...

BACKGROUND Fibroblast-seeded collagen sponges have been used for the treatment of skin defects and skin ulcers. However, the viability of the fibroblasts after implantation is still unknown. The objective of this study was to investigate the viability and distribution of autologous and allogeneic fibroblasts after implantation and to clarify which type is more effective for wound healing. MAT...

The fibrocartilaginous menisci are load-bearing tissues vital to the normal functioning of the knee. Removal of damaged regions of the meniscus subsequent to injury impairs knee function and predisposes patients to osteoarthritis. In this study, we employed biodegradable nanofibrous scaffolds for the tissue engineering of the meniscus. Non-aligned (NA) or fiber-aligned (AL) nanofibrous scaffold...

Supersonic expansion is a very powerful tool to produce an atomic beam with a well defined velocity and, by seeding a test gas in such an expansion, the energy of the test gas can be transferred, at least partially, to the very-low-temperature carrier gas. The case usually studied is the one of a heavy gas seeded in a light carrier gas and, in this case, the parallel temperature of the seeded g...

Over three consecutive years in central Mississippi, sweetgum (Liquidambar styraci/lua L.) and sycamore (Platanus occidentalis L.) fruits had nearly reached fullsize by late June. Sweetgum seeds were physiologically mature by mid-August, but dry weight increased until late September. As sweetgum seeds matured, the crude fat level rose to 27 percent of seed dry weight. During maturation, concent...

objective (s): the scarcity of articular cartilage defect to repair due to absence of blood vessels and tissue engineering is one of the promising approaches for cartilage regeneration. the objective of this study was to prepare an extracellular matrix derived decellularized bovine articular cartilage scaffold and investigate its interactions with seeded rat bone marrow mesenchymal stem cells (...

Sugars, including fructose, glucose, and sucrose, contribute signifi cantly to the fl avor and consumer acceptance of snap beans (Phaseolus vulgaris L.). Differences between dry and snap bean cultivars and among snap bean cultivars in the patterns of accumulation of sugars have been observed. In ‘Eagle’, a white-seeded, largesieve snap bean cultivar, fructose and glucose concentrations in devel...

The biosynthesis and control of vitamin B6 in bacteria could be studied more easily if an organism which produced large amounts of this family of compounds could be found. Unfortunately, the measurements of bacterial vitamin B6 that have been reported have often failed to include the total extracellular vitamin B6, and thus they do not adequately reflect the total vitamin B6 in the whole cultur...
