Introduction Tissue Engineered Mucosa (TEM) was originally designed to reconstruct large oral defects remaining in the oral cavity after oncological resection. TEM consists of human keratinocytes and fibroblasts seeded onto an a-cellular dermal scaffold . Previous study 2 in our laboratory showed that TEM could also be used as a tool to study the biological response to ionizing radiation (IR), ...

Beta-lactamase confers resistance to penicillin-like antibiotics by hydrolyzing their beta-lactam bond. To combat these enzymes, inhibitors covalently cross-linking the hydrolytic Ser70 to Ser130 were introduced. In turn, mutant beta-lactamases have emerged with decreased susceptibility to these mechanism-based inhibitors. Substituting Ser130 with glycine in the inhibitor-resistant TEM (IRT) mu...

BACKGROUND Transanal endoscopic microsurgery (TEM) for the treatment of early-stage rectal cancer has attracted attention due to its advantages of reduced surgical trauma, fewer complications, low operative mortality, rapid postoperative recovery and short hospital stay. However, there are still significant controversies regarding TEM for the treatment of rectal cancer, mainly related to the pr...

Over the last decade there has been significant progress in the synthesis of inorganic and hybrid inorganic-organic nanoparticles in solution. Optimizing the synthesis conditions is often dependent on structural characterization of the nanoparticles. Transmission Electron Microscopy (TEM) provides a method for structural characterization that provides both high-resolution details of individual ...

Chronic wound management represents a significant burden on healthcare systems and negatively impacts on the quality of patient life. New strategies to understand and identify wounds that will not heal in a normal manner are required. Tumour endothelial marker‑8 (TEM‑8) has been implicated in the wound healing and angiogenesis processes. TEM‑8 expression was examined at the transcript level in ...

PURPOSE To determine the potential economic implications resulting from oral temozolomide (TEM) compared with intravenous (IV) dacarbazine (DTIC) for metastatic melanoma. PATIENTS AND METHODS We performed a cost-effectiveness (CE) analysis using hazard ratios (HRs) from the phase III (Schering I95-018) trial comparing TEM 200 mg/m(2)/d orally for 5 days every 28 days with DTIC 250 mg/m(2)/d I...

OBJECTIVES To investigate the occurrence and the diversity of Ambler class A ESBLs among Enterobacteriaceae from different Portuguese clinical settings over a 2 year period (2002-04). METHODS One hundred and nine extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae isolates from five geographically distant health institutions in Portugal were studied. ESBLs were characterized ...
