Mitochondrial antibodies (AMA).

The Ama and Chiropractic

The State and Territory Competition Policy Reform Acts of 1995 applied the competitive conduct rules to Australian professions, including the medical profession, for the first time. The competitive conduct rules are basically the prohibitions on restrictive trading practices contained in Part IV of the Trade Practices Act. As the medical profession was effectively sheltered from the operation o...

"This ain't my daddy's AMA".

Principles Governing AMA Web Sites

THE INTERNET HAS PERMITTED physicians, other health care professionals, patients, and other consumers to quickly access medical information in unprecedented volume. Such access has the potential to speed the transformation of the patient-physician relationship from that of physician authority ministering advice and treatment (with sometimes questionable patient understanding and adherence to re...

Lethal and amanitin-resistance mutations in the Caenorhabditis elegans ama-1 and ama-2 genes.

Mutants of Caenorhabditis elegans resistant to alpha-amanitin have been isolated at a frequency of about 1.6 x 10(-6) after EMS mutagenesis of the wild-type strain, N2. Four new dominant resistance mutations have been studied genetically. Three are alleles of a previously identified gene, ama-1 IV, encoding the largest subunit of RNA polymerase II. The fourth mutation defines a new gene, ama-2 ...

Mitochondrial Antibodies in Primary Biliary Cirrhosis

The antigen reacting with complement-fixing antibodies in the sera of patients with primary biliary cirrhosis was localized predominantly in the mitochondrial fraction of tissue homogenates obtained by differential centrifugation. Purified mitochondrial preparations had a high content of the antigen whereas purified lysosomes failed to fix complement with PBC sera. Analysis of a number of fract...
