Molecular imaging is the noninvasive visualization of normal as well as abnormal cellular processes at a molecular or genetic level of function. It is used to provide characterization and measurement of biological processes in living animals and humans (in vivo). The discipline of molecular imaging evolved rapidly over the past decade through the integration of cell biology, molecular biology a...

Multi-agent systems are realized as a practical solution to the problem of constructing flexible and dynamic environments. Understanding such systems needs a high-level visual view of how the system operates as a whole to achieve some application related purpose. In this paper, we demonstrate how a visual high-level view called Use Case Maps (UCMs) may help in visualizing, understanding, and de...

Children are by nature apprehensive and do perceive pain as adults do. But young children, do not always or readily complain vocally of discomfort. When chronic discomfort is punctuated by acute distress of diagnostic or therapeutic intrusions, relief may be obtained for some children by various analgesic-anesthetic agents. Although the ideal 'intravenous' analgesic-anesthetic agent is yet to b...

The principal findings of a study for further evaluating paraffin baiting as a routine laboratory diagnostic procedure in the isolation of Nocardia asteroides, the etiological agent of nocardiosis, are reported.

Bartonella henselae was discovered a quarter of a century ago as the causative agent of cat scratch disease, a clinical entity described in the literature for more than half a century. As diagnostic techniques improve, our knowledge of the spectrum of clinical disease resulting from infection with Bartonella is expanding. This review summarizes current knowledge regarding the microbiology, clin...

Mollaret meningitis is a rare form of meningitis that is recurrent, aseptic, mild, and self-limiting. When initially described by Mollaret, this form of aseptic meningitis had no identifiable infecting agent. New sophisticated diagnostic tools have now identified Herpes simplex type 2 virus as the most commonly isolated agent. The case presented in this article is of a patient with a history of...

In Brazil, the main etiologic agent of Leishmaniasis that frequently presents with mucosal involvement belongs to the Viannia subgenus. The therapeutic conduct in this disease depends on the parasitological diagnosis, and classical methods are restricted in identifying the agent. In this paper we describe a polymerase chain reaction (PCR), which uses primers designed from mini-exons repetitive ...

The authors examine equine viral arteritis, emphasising occurrence of the disease, distribution of the caused agent, clinical features, modes of transmission, pathogenesis, the carrier state, diagnostic tests and control measures including vaccination.
