Ocular abnormalities in a herd of Old Kladruber Horses: A cross-sectional study.

Objective: To screen a closed herd of the Old Kladruber Horses (OKH) for the prevalence of ocular disorders and report normal ocular variations.

Animals Studied: Two hundred and sixty-one horses, 122 Old Kladruber Gray Horses, and 139 Old Kladruber Black Horses owned by the National Stud Farm Kladruby nad Labem, Czech Republic, were included in the study with signalment and pedigree information recorded.

Procedures: Bilateral ocular examination of manually restrained horses was performed in a darkened environment by a single examiner (RA), using a portable slit-lamp biomicroscope, direct ophthalmoscope, and monocular indirect ophthalmoscopy using a Finnoff transilluminator and 20 D condensing lens.

Sarcosine influences apoptosis and growth of prostate cells via cell-type specific regulation of distinct sets of genes.

Background: Sarcosine is a widely discussed oncometabolite of prostate cells. Although several reports described connections between sarcosine and various phenotypic changes of prostate cancer (PCa) cells, there is still a lack of insights on the complex phenomena of its effects on gene expression patterns, particularly in non-malignant and non-metastatic cells.

Methods: To shed more light on this phenomenon, we performed parallel microarray profiling of RNA isolated from non-malignant (PNT1A), malignant (22Rv1), and metastatic (PC-3) prostate cell lines treated with sarcosine.

Sequence analysis of ribosomal and mitochondrial genes of the giant liver fluke Fascioloides magna (Trematoda: Fasciolidae): intraspecific variation and differentiation from Fasciola hepatica.

Complete sequences of ribosomal and mitochondrial genes of the giant liver fluke Fascioloides magna are presented. In particular, small subunit (18S) and internal transcribed spacers (ITS1 and ITS2) of the ribosomal gene (rDNA), as well as cytochrome c oxidase subunit I (cox1) and nicotinamide dehydrogenase subunit I (nad1) of the mitochondrial DNA (mtDNA), were analyzed. The 18S and ITS sequences were compared with previously published sequences of the liver fluke Fasciola hepatica.

The giant liver fluke Fascioloides magna (Bassi 1875) in cervids in the Czech Republic and potential of its spreading to Germany.

The giant liver fluke Fascioloides magna is an important parasite of cervids in Europe. From September 2003 to December 2005, faecal samples and livers of red deer (Cervus elaphus) and fallow deer (Dama dama) were investigated to determine the current distribution of the fluke in the Czech Republic. Faecal samples were collected from 20 different areas, and livers of hunted deer were dissected from each locality to confirm F.
