Prognostic value of colonic and peripheral venous lactate measurements in horses with large colon volvulus.

Objective: To determine the prognostic value of (1) colonic venous lactate or peripheral lactate values obtained before and after manual correction of a large colon volvulus and (2) a combination of variables including pelvic flexure biopsy.

Study Design: Prospective clinical study.

Animals: Forty adult horses in which large colon volvulus was diagnosed intraoperatively.

Gene biomarkers in peripheral white blood cells of horses with experimentally induced osteoarthritis.

Objective: To use microarray analysis to identify genes that are differentially expressed in horses with experimentally induced osteoarthritis.

Animals: 24 horses.

Procedures: During arthroscopic surgery, a fragment was created in the distal aspect of the radiocarpal bone in 1 forelimb of each horse to induce osteoarthritis.

Macronuclear molecules encoding actins in spirotrichs.

The nucleotide sequences of 16 newly reported and 8 previously reported actin-encoding macronuclear DNA molecules in spirotrichs have been compared. As described for the eight previously reported molecules, the first 50 bases (noncoding) inside the telomere at both 5' strands in additional actin molecules are purine-rich. This anomalous base composition might serve as a signal to identify macronuclear molecules in micronuclear DNA during development.
