In order to investigate whether suppression of the p16 gene is mediated by histone H3 acetylation in 4 canine lymphoid tumor cell lines, the gene's acetylation status was examined. In 2 canine lymphoid tumor cell lines with low p16 mRNA expression (GL-1 and UL-1), the acetylation level was lower than that in CL-1 cells with high p16 mRNA expression. The expression of the p16 gene in these 2 cell lines was markedly restored after culture in the presence of a histone deacetylase inhibitors trichostatin A, indicating that p16 was inactivated by hypoacetylation...

The effect of methylprednisolone sodium succinate (MPSS) therapy was studied in 50 dogs with surgically treated Hansen type I thoracolumbar intervertebral disk herniation (TL-IVDH). Administration of MPSS significantly reduced the swelling of the spinal cord. The sensitivity of localization of disk extrusion using myelography in the MPSS group was 92.3%, and in the non-administration group was 83.3%. No significant difference in recovery rate or length of recovery time was found between the two groups. Administration of MPSS reduced spinal cord swelling, but has no effect on recovery in dogs after surgery for TL-IVDH...

Coxsackievirus and adenovirus receptor (UXADR) is an integral membrane protein that serves as a receptor for coxsackie B viruses and adenovirus types 2 and 5. Previous studies demonstrated that Fowl adenovirus (FAV) can also utilize Homo sapiens CXADR to infect cells. FAV is a double-stranded DNA virus of the family Adenoviridae. FAV causes inclusion body hepatitis and hydropericardium syndrome in chickens. In addition, FAV serotypes 1 and 8 have recently been shown to cause gizzard erosion in chickens. These chicken diseases and growth insufficiency caused by FAV infection result in great economic loss...

A two-day-old female Toggenburg goat with thoracic ectopia cordis (EC) was diagnosed via radiography and computed tomography. The goat was born with EC, defects of the sternum and a supra-umbilical abdominal wall, but without the presence of Cantrell's syndrome. Necropsy and histopathological findings indicated the affected kid had malformation of the heart with an enlarged left ventricle. The findings showed the heart (9 x 5 x 5 cm) stayed outside the thorax, and was covered by a semitransparent membrane. This report is the first to describe a case of thoracic EC in a goat whose sternum was not developed fully and was not connected to the ribs...

Water intoxication is a common disorder in calves and is usually characterized by transient hemoglobinuria. In contrast, the condition is very rare in adult cattle, with few reports on naturally occurring cases. In the present report, four female Japanese Black cattle, aged 16-25 months, showed neurological signs when they drank water following a water outage. Hemoglobinuria was not grossly observed, while severe hyponatremia was revealed by laboratory tests. Autopsy indicated cerebral edema with accumulation of serous fluid in expanded Virchow-Robin spaces...
