BACKGROUND Recent studies have revealed that bronchoalveolar lavage (BAL) fluid contains previously unappreciated communities of bacteria. In vitro and in vivo studies have shown that host inflammatory signals prompt bacteria to disperse from cell-associated biofilms and adopt a virulent free-living phenotype. The proportion of the lung microbiota that is cell-associated is unknown. RESULTS F...

We report a case of a 30-year-old woman who had complained of lower abdominal distension. She was noted to have a history of primary mucinous tumor of the left ovary (13.2 × 9.9 × 10.4 cm) that was removed surgically. Two years later she developed the same tumor on her left ovary (8.7 × 6.0 × 6.9 cm) and also had appendiceal mucinous tumor accompanied with acellular PMP. Final pathology reveale...

Oncological resection of advanced carcinoma in the head and neck region results in vast defects. The free latissimus dorsi musculocutaneous flap (FLDMF) is one of the most commonly used flaps for the repair of complex head and neck defects. We tried to modify FLDMF to multiple segments or combine it with acellular dermis to fit through-and-through defects in the oral-facial region during the la...

AIM To investigate the transformation of characteristics of epidermal cells from foreskin which were used to reconstruct male rabbit anterior urethra in combination with acellular collagen matrices. METHODS In three rabbits, autologous foreskin epidermal cells were isolated, expanded in vitro, and seeded (inoculated) onto a tubular acellular collagen matrix, acquired from allogeneic rabbit bl...

Several studies have reported on certain aspects of the characteristics of different sites within a keloid lesion, but detailed studies on the keloid dermis at different depths within a keloid lesion are scarce. The aim of this study was to investigate the histology of the keloid dermis at different depths. This study included 19 keloid tissue samples that were collected from 19 patients and 19...

The aim of this study was to compare two different acellular scaffolds: natural and synthetic, for urinary conduit construction and ureter segment reconstruction. Acellular aortic arch (AAM) and poly(L-lactide-co-caprolactone) (PLCL) were used in 24 rats for ureter reconstruction in both tested groups. Follow-up period was 4 weeks. Intravenous pyelography, histological and immunohistochemical a...
