A nonaqueous potentiometric titration study of the dissociation of t-butyl methacrylate-methacrylic acid copolymers.
The dissociation of t-butyl methacrylate-methacrylic acid copolymers in dimethyl sulfoxide was analyzed by a nonaqueous potentiometric titration technique. The negative logarithm of the dissociation constant of the monomer unit of a methacrylic acid (MAA) monotonously increased with the increasing degree of dissociation corresponding to the titrant/MAA amount ratio, and was highly influenced by...
متن کاملHLA association with antipyretic analgesics-induced Stevens-Johnson Syndrome / toxic epidermal necrolysis with severe ocular surface complications in japanese patients
Background Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), are severe adverse drug reactions which are very rare, acute, serious, and potentially fatal. They exhibit characteristic symptoms not only in the skin, but also in the mucosal tissues such as ocular surface, oral cavity, and genitals. Although antipyretic analgesics (AAs) are some of the most frequent causative dru...
متن کاملAssessment of the (14C) aminopyrine breath test in liver disease.
Different methods of performing the (14C) aminopyrine breath test have been assessed. A tracer dose of 2 muCi without a loading dose and with a single breath collection at two hours was the method selected, since it gave the best discrimination between patients with hepatocellular diseases and normal subjects (5.2 +/- 0.2%, mean +/- SEM). Reduced values occurred in patients with chronic active ...
متن کاملWater in nonaqueous solvents*
The possibility and usefulness of sinple liquid models is reported. The importance of van der Waals forces for liquid water and aqueous solutions is discussed and compared with the solubility of water in nonpolar solvents and as well as of nonpolar solvents in water. Both systems could be understood as equilibrium of few water monomers. The network of H-bonded water molecules seems to be less i...
