Type IV pilin monomers assemble to form fibers called pili that are required for a variety of bacterial functions. Pilin monomers oligomerize due to the interaction of part of their hydrophobic N-terminal alpha-helix. Engineering of a truncated pilin from Pseudomonas aeruginosa strain K122-4, where the first 28 residues are removed from the N terminus,(More)
Actinic keratoses (AKs) are one of the most common conditions that are treated by dermatologists and they have the potential to progress to squamous cell carcinoma if left untreated. Photodynamic therapy (PDT) has emerged as a novel and versatile method of treating those lesions. Topical preparations of aminolevulinic acid and methyl aminolevulinate are(More)
In this study, we cloned and sequenced the Helicobacter pylori genes encoding fumarate reductase (FRD). H. pylori frdA, frdB and frdC specify polypeptides of 715, 245 and 254 aa, respectively. The deduced aa sequences of FrdA and FrdB are highly homologous to those of the corresponding subunits of Wolinella succinogenes FRD and also exhibit a significant(More)
BACKGROUND The cutaneous manifestations of graft-versus-host disease (GVHD) can be classified into acute and chronic forms. Acute GVHD is defined as a skin eruption that manifests within 100 days of transplantation, whereas chronic GVHD refers to cutaneous changes that appear 100 days or more posttransplantation. OBJECTIVE Although most chronic forms fall(More)
BACKGROUND Cutaneous squamous cell carcinoma (SCCA) is an important cause of death in patients with the severe form of recessive dystrophic epidermolysis bullosa (RDEB). These cancers often present with features that are different from those of actinically induced SCCA. OBJECTIVE To emphasize the unusual features with which SCCA can present in RDEB and(More)
