ANIMALS 6 healthy Beagles. PROCEDURES 12 ablation lesions were created in the liver of the dogs (2 lesions/dog). Ablation lesions were evaluated by use of conventional ultrasonography, strain elastography, and contrast-enhanced ultrasonography immediately after (time 0), 30 to 60 minutes after, and 3 days after RFA, and by use of CT 30 minutes and 3 days after RFA...

OBJECTIVE To evaluate gene expression and DNA copy number in adipose tissue-derived stromal cells (ADSCs) and in ADSC-derived neurosphere-like cell clusters (ADSC-NSCs) generated from tissues of chronically paraplegic dogs. ANIMALS 14 client-owned paraplegic dogs. PROCEDURES Dorsal subcutaneous adipose tissue (< 1 cm(3)) was collected under general anesthesia; ADSCs were isolated and cultured. Third-passage ADSCs were cultured in neural cell induction medium to generate ADSC-NSCs. Relative gene expression of mesenchymal cell surface marker CD90 and neural progenitor marker nestin was assessed in ADSCs and ADSC-NSCs from 3 dogs by quantitative real-time PCR assay; expression of these and various neural lineage genes was evaluated for the same dogs by reverse transcription PCR assay...

OBJECTIVE To determine whether passive ureteral dilation (PUD) would occur after an indwelling ureteral stent was left in place in healthy dogs for 2 or 6 weeks, ureteroscopy would be possible at the time of stent removal, and PUD would be reversible after stent removal. ANIMALS 5 healthy adult female Beagles. PROCEDURES A ureteral stent was cystoscopically placed in each ureter of each dog with fluoroscopic guidance (week 0). One stent was removed from 1 ureter in each dog after 2 weeks (ureter group 1), and the other was removed after 6 weeks (ureter group 2); removal timing was randomized...

OBJECTIVE To assess the effect of cold storage (CS) on immediate posttransplantation function of renal autografts in cats. ANIMALS 15 healthy 1-year-old cats. PROCEDURES Cats were assigned to 2 groups and underwent autotransplantation of the left kidney followed by nephrectomy of the right kidney. The left kidney was autotransplanted either immediately (IT group; n = 6) or after being flushed with a cold sucrose phosphate solution and stored on ice while the implant site was prepared (CS group; 9). Serum creatinine and BUN concentrations were monitored daily and autografts were ultrasonographically examined intermittently for 14 days after surgery...

OBJECTIVE To evaluate effects of position, time in that position, and positive end-expiratory pressure on ground-glass opacity caused by physiologic atelectasis on lung CT images and to determine effects of recumbency position before CT. ANIMALS 6 healthy Beagles. PROCEDURES In a crossover study, dogs were placed in 4 positions (sternal, dorsal, right lateral, and left lateral recumbency) for 2 holding times (30 and 60 minutes). Dogs were then repositioned in sternal recumbency, and CT was performed at 2 positive end-expiratory pressures (0 and 15 mm Hg)...
