Lactic acidosis is associated with both inherited and acquired metabolic diseases. Lactic acid metabolism in the presence of altered gluconeogenesis, anaerobic glycolysis, and acid-base balance is a major factor in many disorders. Lactic acid can be formed only from pyruvic acid; therefore, disorders that increase pyruvate concentration, enhance lactic acid formation, or reduce lactic acid Process for purifying resorbable polyesters Abstract. The invention relates to the purification of polymers, particularly resorbable polyesters, using shear fields produced mechanically or by fluid dynamics.
