Resistance of Thermus spp. to potassium tellurite
Two members of the genus Thermus were examined for their resistance to toxic inorganic compounds. They both proved to be fairly resistant to tellurite and selenite and to many other heavy metal salts. Cell extracts of ...
Purification and biochemical characterization of tellurite-reducing activities from Thermus thermophilus HB8.
Cell-free extracts of Thermus thermophilus HB8 catalyze the in vitro, NADH-dependent reduction of potassium tellurite (K2TeO3). Three different protein fractions with tellurite-reducing activities were identified. Two ...
Dieulafoy's vascular malformation as a cause of massive and recurrent gastric hemorrhage Malformación vascular de Dieulafoy como causa de hemorragia gástrica masiva y recurrente.
We demonstrated a Dieulafoy-type vascular malformation in 10 patients with upper gastrointestinal bleeding. Most patients had a history of prior bleeding and were older than 60 years of age. A mean of 2.6 endoscopic ...
A retrospective analysis of 74 patients with gallstone ileus detected during the period between 1975 and 1987 was performed at the Surgical Department. The group comprised 55 females and 19 males, with a mean age of 64.8 ...
Soybean proteins: Alternative blocking agents for immunoassays using nitrocellulose or plastic solid phases
The values of soybean proteins (SBP) and bovine serum albumin (BSA) as blocking agents were compared in immunoradiometric (IRMA), western immunoblotting (WIBA) and immunodot (IDA) assays. Protein purification, from soybean ...
Aminochrome induces microglia and astrocyte activation
Aminochrome has been suggested as a more physiological preclinical model capable of inducing five of the six mechanisms of Parkinson's Disease (PD). Until now, there is no evidence that aminochrome induces glial activation ...
