Rotavirus G3P[3] strains have been reported from a variety of species including humans, cats, dogs, monkeys, goats, and cows. Here, we report the characterization of the first human G3P[3] rotavirus from East Asia identified in a 2-year-old child who was treated in a hospital's emergency ward in Taiwan in February 2005. Sequence and phylogenetic analysis demonstrated a close genetic relationship between the VP4, VP6, VP7, and NSP4 genes of Taiwanese G3P[3] strain 04-94s51 and an Italian canine strain isolated a decade ago, suggesting a canine origin for the Taiwanese strain. In contrast, the Taiwanese strain was only moderately related to well-characterized canine-origin human G3P[3] strains Ro1845 and HCR3, suggesting a distinct origin for the rotavirus strain from Taiwan.

Mucosal melanoma is a rare melanoma subtype associated with a poor prognosis and limited existing therapeutic interventions, in part due to a lack of actionable targets and translational animal models for preclinical trials. Comprehensive data on this tumour type are scarce, and existing data often overlooks the importance of the anatomical site of origin. We evaluated human and canine oronasal mucosal melanoma (OMM) to determine whether the common canine disease could inform the rare human equivalent.

Background: Lower urinary tract disease is a common clinical condition in dogs, usually presenting with dysuria, pollakiuria and haematuria. Diabetes mellitus is a predisposing factor for urinary tract infection in both humans and dogs and does not necessarily present with clinical signs. In this case report, we describe for the first time a case of cystitis glandularis in a dog with diabetes mellitus, associated with Escherichia coli urinary tract infection.

Biological effects of ionizing radiation vary with radiation quality, which is often expressed as the amount of energy deposited per unit length, i.e., linear energy transfer (LET).

Biological effects of ionizing radiation vary not merely with total dose but also with temporal dose distribution. Sparing dose protraction effects, in which dose protraction reduces effects of radiation have widely been accepted and generally assumed in radiation protection, particularly for stochastic effects (e.g.

Genomic imprinting is an epigenetic process that results in parent-of-origin effects on mammalian development and growth. Research on genomic imprinting in domesticated animals has lagged due to a primary focus on orthologs of mouse and human imprinted genes. This emphasis has limited the discovery of imprinted genes specific to livestock.
