Background: Emphysematous bullae, defined as airspaces of greater than or equal to one centimeter in diameter, have a variety of etiologies such as tobacco use and alpha-1 antitrypsin being the most common. Emphysematous bullae have also been reported in patients

Cecropin B is a small antibacterial peptide from the giant silkmoth Hyalophora cecropia. To reveal the potential of this peptide for engineering bacterial disease resistance into crops, several cecropin B gene constructs were made either for expression in the cytosol or for secretion. All constructs

Giant bullae occur most often in individuals who chronically inhale tobacco smoke. The natural history of these bullae is unpredictable, although the majority of them increase gradually in size and cause worsening respiratory function. Complete spontaneous resolution of a giant bulla is a rare

Unlike microbes known in his time, the first virus (that of tobacco mosaic disease) was discovered by Ivanoski in 1892 because it was not retained by Chamberland's porcelain candles. For more than a century afterward, viruses were equated with this simple property that is still extensively used

Mesenteric arterial branch aneurysms are rare. Giant, multiple, mesenteric branch artery aneurysms are even more uncommon, and only a few reports exist in the literature. We describe a 73-year-old asymptomatic female found to have an abdominal bruit and subsequently diagnosed with multiple
