The current study used 3 types of carrageenan (denoted here as Car)-κ, ι, and λ-to prepare a jelly vehicle for acetaminophen (AAP), and then compared their usefulness as jelly vehicles. The rheological characteristics of each preparation were assessed and then drug elution from the preparation was assessed using dissolution testing. The behavior of each preparation when immersed in water was al...

The retarding effect of deuterium on biological processes has been a matter of interest to many investigators. However, the early studies in this connection were concerned mainly with the biological effects of deuterium when it was present in excess amounts in the water of the medium. Little work appears to have been done on the effect of deuterium on the rates of biological reactions in which ...

The aim of this study was to investigate the validity of the Tanita TBF 300A leg-to-leg bioimpedance analyzer for estimating fat-free mass (FFM) in Bangladeshi children aged 4-10 years and to develop novel prediction equations for use in this population, using deuterium dilution as the reference method. Two hundred Bangladeshi children were enrolled. The isotope dilution technique with deuteriu...

A significant operational problem impacting upon the Space Shuttle program involves the astronaut's ability to safely egress from the Orbiter during an emergency situation. Following space flight, astronauts display significant movement problems. One variable which may contribute to increased movement ataxia is deuterium (D^O), an isotope of hydrogen/ Deuterium is present in low levels within t...
