The present paper reports evidence of an immunological relationship between one variety or type of the yeast Saccharomyces cerevisi~e and the Type II variety of Diplococcus pn,umoni~e (Pneumococcus). The immunological interrelationships among the different yeasts have never been well established, but it is certain that all of the yeasts included by the species term Saccharomyces cerevisi~ are n...

cystic hydatid disease (hydatidosis) is the most serious tape-worm infection prevalent in the cattle and sheep raising area of the world. hydatidosis in man (as an accidental host) caused by infection with the ova containing larval stage of echinococcus spp. in the last decade different techniques have been employed for the serological diagnosis of hydatid disease, such as iha, ifa, elisa, ccle...

INTRODUCTION A variety of radiolabelled minigastrin analogues targeting the cholecystokinin 2 (CCK2) receptor were developed and compared in a concerted preclinical testing to select the most promising radiotracer for diagnosis and treatment of medullary thyroid carcinoma (MTC). DOTA-DGlu-DGlu-DGlu-DGlu-DGlu-DGlu-Ala-Tyr-Gly-Trp-Met-Asp-Phe-NH2 (CP04) after labelling with (111)In displayed exce...

Traditional newborn dried blood spot screening (NDBS) has expanded in recent years to include upwards of 50 different conditions in many states. Once the screening tests are complete, the residual blood specimens (RBSs) that remain are most often available for quality assurance and public health research. The articles by Botkin et al1 and Bombard et al2 contained in this issue of Pediatrics inv...

The ability to use dry blood spots (DBSs) on filter paper for the analysis of urea levels could be an important diagnostic tool for areas that have limited access to laboratory facilities. We developed a method for the extraction and quantification of urea from DBSs that were stored on 3M Whatman filter paper and investigated the effect of long-term storage on the level of urea in DBSs. DBSs of...

Despite the availability of the PAP test, cervical cancer continues to cause considerable morbidity and mortality. Many women default cervical cytology for a variety of reasons. This demands the development of alternative screening strategies, such as HPV testing on self-procured cervical-vaginal specimens in order to capture this group of women. We investigated the self-procured air-dried vagi...

Human noroviruses (HuNoVs), a leading cause of food-borne gastroenteritis worldwide, are easily transferred via ready-to-eat (RTE) foods, often prepared by infected food handlers. In this study, the transmission of HuNoV and murine norovirus (MuNoV) from virus-contaminated hands to latex gloves during gloving, as well as from virus-contaminated donor surfaces to recipient surfaces after simulat...

BACKGROUND Food adulteration remains a major global concern. DNA fingerprinting has several advantages over chemical and morphological identification techniques. DNA microarray-based fingerprinting techniques have not been used previously to detect adulteration involving dried commercial samples of closely related species. Here we report amplification of low-level DNA obtained from dried commer...
