The E1B 19K protein is a potent apoptosis inhibitor and the putative adenovirus Bcl-2 homolog. To investigate the mechanism of apoptosis regulation, 19K-interacting cellular proteins were identified using the yeast two-hybrid system, and Bax was one of seven 19-K interacting clones. Residues 50-78 of Bax containing a conserved region designated Bcl-2(More)
Expression of the E1B 19K protein is required to inhibit apoptosis induced by E1A during adenovirus infection and transformation. E1B 19K is homologous to Bcl-2 in function and the two proteins also share limited amino acid sequence homology. Consequently, the E1B 19K and Bcl-2 proteins bind to and inhibit the cellular death-inducing proteins Bax, Bak and(More)
In patients with cystic fibrosis (CF), the isolation of filamentous fungi, in particular Aspergillus spp. in the respiratory secretions is a common occurrence. Most of these patients do not fulfil the clinical criteria for a diagnosis of allergic bronchopulmonary aspergillosis (ABPA). The clinical relevance of filamentous fungi and whether antifungal(More)
Filamentous fungi are commonly isolated from the respiratory tract of CF patients, but their clinical significance is uncertain and the reported incidence variable. We report on the degree of Aspergillus fumigatus airway colonization in a tertiary pediatric CF cohort, evaluate the sensitivity of routine clinical sampling at detecting A. fumigatus, and(More)
The Bcl-2 homologous region 3 (BH3) is sufficient for interaction of pro-apoptotic with anti-apoptotic Bcl-2 family members, and functional antagonism may determine whether cell survival or death is the outcome of this protein-protein interaction. To address the biological role of BH3, two Bax-Bcl2 chimeras were generated in which 13 amino acids(More)
Lung infections with Mycobacterium abscessus, a species of multidrug-resistant nontuberculous mycobacteria, are emerging as an important global threat to individuals with cystic fibrosis (CF), in whom M. abscessus accelerates inflammatory lung damage, leading to increased morbidity and mortality. Previously, M. abscessus was thought to be independently(More)
Mycobacterium tuberculosis strain CH, the index isolate linked to a major tuberculosis outbreak associated with high levels of transmissibility and virulence, was characterized by microarray analysis by use of a PCR product array representative of the genome of M. tuberculosis strain H37Rv. Seven potential genomic deletions were identified in CH, five of(More)
Diabetic foot osteomyelitis can be managed medically with systemic antibiotics alone or surgically by removing infected bone (1,2). Localized delivery of antibiotics directly to the bone offers a way to achieve an optimal concentration of chosen antibiotics at the site of infection. Antibiotics have been delivered directly into wounds using various(More)
Invasive ocular infections due to Pseudomonas aeruginosa infections are rare. Previous studies have reported cases in immunocompromised hosts, patients after surgery (radial keratotomy), aswell as in neonates.Herein,wepresent the case of a healthy male infant who at 9 months of age presented to the emergency department with a right upper eyelid preseptal(More)
