Spontaneously occurring cardiovascular lesions in commonly used laboratory animals

Antibiotics used most commonly to treat animals in Europe

The Heads of Medicines Agencies and the Federation of Veterinarians of Europe undertook a survey to gain an insight into European prescribing of antibiotics for animals, in particular to highlight the diseases for which antibiotics are most commonly said to be prescribed and which different classes, including human critically important antibiotics (CIAs). The survey was completed by 3004 practi...

Characteristics of structures and lesions of the eye in laboratory animals used in toxicity studies

Histopathology of the eye is an essential part of ocular toxicity evaluation. There are structural variations of the eye among several laboratory animals commonly used in toxicity studies, and many cases of ocular lesions in these animals are related to anatomical and physiological characteristics of the eye. Since albino rats have no melanin in the eye, findings of the fundus can be observed c...

Commonly used respiratory and pharmacologic interventions in the echocardiography laboratory.

Respiratory and pharmacologic interventions are used during auscultation of heart sounds. These same principles may be utilized in the echocardiography laboratory to aid diagnosis. Four physical maneuvers and one pharmacologic intervention performed in the echocardiography laboratory are described. A brief discussion of applications in specific clinical situations is then presented. The Valsalv...

Deposition of carbon nanotubes in commonly used sample filter media

There is no single standard technique or methodology to characterize the size, structure, number, and chemical composition of airborne carbon nanotubes.  Existing analytical instruments and analytical techniques for evaluating nanoparticle concentrations cannot simultaneously provide morphology, state of agglomeration, surface area, mass, size distribution and chemical composition data critical...
