"We are what we eat!" Invasive intestinal mucormycosis: A case report and review of the literature.

Gastrointestinal mucormycosis is an uncommon, life-threatening, angioinvasive infection with only one previous report of disease involving the jejunum. We present a case of invasive jejunal mucormycosis and review the literature, highlighting the rare clinical presentation and the value of molecular diagnostic methods. Given the global increase in patient populations at risk of mucormycosis, clinicians need to maintain a high index of suspicion and perform timely and appropriate evaluation to improve patient outcome.

Mechanisms of clastogen-induced chromosomal aberrations: a critical review and description of a model based on failures of tethering of DNA strand ends to strand-breaking enzymes.

Most theories of the mechanisms of chromosomal aberrations involve the concepts of clastogens directly acting on DNA to produce strand breaks, and subsequently, the survival of these directly caused DNA strand breaks - or misrepairs of them - through to metaphase when they appear as chromosomal 'breaks' or translocations. Nevertheless, various observations are inconsistent with these theories such as the fact that many chemical clastogens (e.g.
