The Epidemiology of Blood-Contaminated Needlestick Injuries Among Veterinarians in Portugal. Needlestick injuries (NIs) are considered a substantial occupational health and safety hazard in contemporary health care practice. Unlike human medicine where much effort has been devoted to reduce the incidence of these events, the same aggressive approach has not been used in veterinary medicine. This study investigated the occurrence of blood-contaminated NIs in Portuguese veterinarians. Parti. 2015. Mesquita, João R.; Sousa, Sofia I. V.; Vala, Helena; Nascimento, Maria S.

Conversion to sirolimus ameliorates cyclosporine-induced nephropathy in the rat - focus on serum, urine, gene and protein renal expression biomarkers. Protocols of conversion from cyclosporine A (CsA) to sirolimus (SRL) have been widely used in immunotherapy after transplantation to prevent CsA-induced nephropathy, but the molecular mechanisms underlying these protocols remain nuclear. This study aimed to identify the molecular pathways and putative biomarkers of CsA-to-SRL conversion in a rat model. Four animal groups ( = 6) were teste during 9. 2014.

Transition from cyclosporine-induced renal dysfunction to nephrotoxicity in an in vivo rat model – focus on mechanisms and biomarkers of kidney fibrosis and proliferation. Cyclosporin A (CsA), a calcineurin inhibitor, remain the cornerstone of immunosuppressive regimens, regardless of nephrotoxicity, which depends on the duration of drug exposure. The mechanisms and biomarkers underlying the transition from CsA-induced renal dysfunction to nephrotoxicity deserve better elucidation, and would help clinical decisions.

Blood Transfusions in Dogs and Cats: Blood Typing, Cross Matching. The blood transfusion (administration of blood) is a resource of veterinary medicine with several indications. Point-of-care blood-typing methods, including both typing cards and rapid gel agglutination, are readily available. Following blood typing, cross matching is performed on one or more donor units of appropriate blood type. Cross matching reduces the risk of transfusion reactions but does n. 2012.

Ear Mites: Tackling a Persistent Problem. A several number of mites have been associated with ear problems, namely otitis externa (Scott et al., 2001).

Feline Calicivirus: unveiling data on viral inactivation. Feline Calicivirus (FCV) is an important and widespread virus of the feline population. As a member of the Caliciviridae family, FCV mutates readily in nature, and this has resulted in the recent emergence of a highly virulent haemorrhagic systemic strain. Despite the increased concern about this feline pathogen, little is still known on potential FCV virucidal compounds. On the other hand several. 2010.
