Sucrose-mediated formation and adhesion strength of biofilms on titanium.

Biofilms consist of bacterial cells surrounded by a matrix of extracellular polymeric substance (EPS), which protects the colony from many countermeasures, including antibiotic treatments. Growth and formation of bacterial biofilms are affected by nutrients available in the environment. In the oral cavity, the presence of sucrose affects the growth of that produce acids that erode enamel and form dental caries.

Evaluation of plasma nucleosome concentrations in dogs with a variety of common cancers and in healthy dogs.

Background: Cell free DNA, in the form of nucleosomes, is released into circulation during apoptosis and necrosis in a variety of diseases. They are small fragments of chromosomes that are composed of DNA wrapped around a histone core made of four duplicate histone proteins forming an octamer. The nucleosome compartment is a relatively uninvestigated area of circulating tumor biomarkers in dogs.

Lactic acid concentration in peritoneal fluid of normal and diseased horses.

Peritoneal fluid from each of 15 clinically healthy horses and five horses with acute abdominal disease was evaluated for lactic acid concentration. The normal range was 2-7--13-4 mg/dl. Simultaneous blood and peritoneal fluid samples from healthy horses revealed consistently lower lactic acid concentrations in the peritoneal fluid than in the blood, whereas peritoneal fluid lactic acid levels were consistently greater than blood levels in the diseased horses.
