Oncogenes induce a reversal of replication’s for tunes N eelsen et al. describe how certain oncogenes can perturb DNA replication and induce DNA damage. Several oncogenes, including Cyclin E and Cdc25A, push cells precipitously into S phase, resulting in numerous DNA double-strand breaks (DSBs). But how S phase deregulation disrupts replication and induces DNA damage is unclear. To fi nd out, N...
We report a rare case of tuberculosis of oral cavity in a 3.5 year-old male who was referred to oral medicine department with a chief complaint of a painless lesion in the oral cavity. Incisional biopsy from the lesion margin depicted histological features of necrotizing granulomatous lesion. Ziehl-Neelsen staining for acid fast bacilli, interestingly, was negative.
Methods Sixty lymph node aspirates from suspected cases of tuberculous lymphadenitis were examined for Mycobacterium tuberculosis by Ziehl neelsen (ZN) staining, culture on a Lowenstein Jensen medium, and cytological examination for findings suggestive of tubercular lymphadenitis. DNA from all the samples was amplified by conventional PCR targeting 123 bp and 240 bp fragments of IS6110 and MPT6...
Using Ziehl-Neelsen-positive slides collected from tuberculosis diagnostic centers in Burkina Faso, we showed that 20% of 80 spoligotyping-positive DNA samples had a characteristic Mycobacterium africanum-specific genomic signature. This result suggests that M. africanum is still present in Burkina Faso at almost the same prevalence as 15-20 years ago.

Background. Atypical mycobacteria, or nontuberculous mycobacteria (NTM), have been barely reported as infective endocarditis (IE) agents. Methods. From January 2010 to December 2013, cardiac valve samples sent to our laboratory as cases of blood culture-negative suspected IE were analyzed by 16S rDNA polymerase chain reaction (PCR). When positive for NTM, hsp PCR allowed species identificatio...
