One of the goals of contemporary cancer research is the development of new markers that facilitate earlier and non-invasive diagnosis. MicroRNAs are non-coding RNA molecules that regulate gene expression; studies have shown that their expression levels are altered in cancer. Recently, extra-cellular microRNAs have been detected in biological...

Histoplasmosis is a relatively rare infectious disease endemic to certain geographic areas such as East Africa, eastern and central United States, western Mexico, Central and South America. Disseminated histoplasmosis has been reported mainly in immunocompromised hosts and in AIDS patients. In this paper we report on a fatal case of undiagnosed...

Actinic keratoses (AKs) are common dysplastic lesions resulting from chronic excessive ultraviolet exposure. Neither the clinical grade of thickness nor the histological grade of dysplasia seems valid predictors of aggressive potential of AKs. Instead, the mutational status in AKs appears to predict well the clinical course. TP53 gene mutations...
