Comparison of Candida ID medium with Sabouraud-chloramphenicol agar for the isolation of yeasts from clinical haematology surveillance specimens [PDF]

Journal of Medical Microbiology, 2002
Candida ID is a new chromogenic medium for the identification of yeasts from clinical specimens. C. albicans produces blue pigmentation, whereas pink pigmentation is produced by C. tropicalis, C lusitaniae, C. guilliermondii and C. kefyr; other Candida species appear white.

Biological specimens for community-based surveillance studies: Method of recruitment matters

Survey Research Methods, 2011
Studies requiring the collection of biological specimens are often difficult to perform and costly. We compare face-to-face and telephone interviews to determine which is more effective for return of self-collected rectal swabs from subjects living in ...

Comparison of nasopharyngeal and oropharyngeal swabs for the diagnosis of eight respiratory viruses by real-time reverse transcription-PCR assays. [PDF]

PLoS ONE, 2011
BACKGROUND: Many acute respiratory illness surveillance systems collect and test nasopharyngeal (NP) and/or oropharyngeal (OP) swab specimens, yet there are few studies assessing the relative measures of performance for NP versus OP specimens.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.
