The rationale of using antibodies comes from the observation that antibodies against specific parasite antigens persist in time and at reasonably stable concentrations, even when transmission is seasonal.
Ultrafine carbonaceous model particles with a count median mobility diameter of about 95 ± 5 nm were produced by spark discharge at a stable concentration of about 2 × 106 cm−3 and continuously monitored for accurate determination of the exposure dose.
Growth of electron concentration (at the stable concentration of background charged impurities in the well) leads to strong increase of mobility and appropriate reduction of resistance due to two simultaneous processes: decrease of hole concentration and growth of screening [1].
Anaesthesia was induced with propofol and maintained with halothane at a stable concentration between 0.85 and 0.95%.
The rate of infusion of replacement solution was coupled to the blood flow, aiming at stable citrate concentrations in the extracorporeal circuit.
Low meta-stable concentration of Nb at the interface, a critical supersaturated concentration of Nb very close to the meta-stable concentration required before the IMC can grow and negligible solid state diffusion in the IMC are identified as the key factors responsible for the observed kinetics of dissolution and interfacial reaction.
To overcome the instability issues and push the RNA nanotechnology field to progress further, a stable platform needs to be produced that can remain stable at low concentrations and high temperatures while resisting RNase degradation.
We also measured the UV-visible spectra and the coldspray ionization (CSI) MS spectra and concluded that the 1-to-1 Zn2+ complex of (GdLa 2− is stable at higher concentrations of Zn2+.
Chemical denaturation by guanidine HCl (GuHCl) of human carbonic anhydrase II (HCA II) leads to a three-state unfolding process (Cm,NI=1.0 and Cm,IU=1.9 M GuHCl) with formation of an equilibrium molten-globule intermediate that is stable at moderate concentrations of the denaturant (1 2 M) with a maximum at 1.5 M GuHCl.
Global analysis of the fluorescence spectral change demonstrated the following folding-unfolding process of the enzyme: N ↔ I1 ↔ I2 ↔ I3 ↔ I4 ↔ I5 ↔ D. These discrete intermediates are stable at urea concentrations of 2.6, 4.1, 4.7, 5.5, 6.6, and 7.7 M, respectively.
