INTRODUCTION The present study examines the question whether the selection of dental students should be based solely on average school-leaving grades (GPA) or whether it could be improved by using a subject-specific aptitude test. METHODS The HAM-Nat Natural Sciences Test was piloted with freshmen during their first study week in 2006 and 2007. In 2009 and 2010 it was used in the dental stude...

Antiserum to a purified type R lipopolysaccharide antigen isolated from Neisseria gonorrhoeae was used in a slide agglutination test and compared with conventional carbohydrate utilization and fluorescent antibody tests to confirm the identity of laboratory cultures classified as typical or "atypical" N. gonorrhoeae. Cultures of Corynebacterium vaginalis, N. meningitidis, N. catarrhalis, N. sic...

BACKGROUND The parasites Toxoplasma gondii (T. gondii) and Neospora caninum (N. caninum) are globally distributed; they infect warm-blooded animals, including many avian species. The aim of this study was to evaluate the presence of these parasites in ostriches from central China. In total, 402 ostrich (Struthio camelus) samples (293 hearts, 77 brains, and 32 serum) from slaughterhouses of the ...

A macroscopic agglutination test for detecting leptospiral antibodies in human sera is described. The test utilizes a stained preparation of non-pathogenic leptospires and is performed on the Brewer diagnostic cards used for bovine brucellosis screening. The agglutination of the stained antigen is more easily observed than the current macroscopic slide test using unstained leptospiral antigens....

OBJECTIVE To develop and evaluate the psychometric properties of a modified Naturalistic Action Test (m-NAT) for Korean patients with impaired cognition. The NAT was originally designed to assess everyday action impairment associated with higher cortical dysfunction. METHODS We developed the m-NAT by adapting the NAT for the Korean cultural background. The m-NAT was modeled as closely as poss...
