The present study was carried out evaluated efficacy of bladder acellular matrix (BAM) as cell delivery vehicle. Smooth muscle cells were harvested by collagenase digestion of rabbit urinary bladder and the cells were cultured in growth medium comprising of 4:1 mixture of DMEM and Ham’s F-12 nutrient mixture supplemented with L-glutamine containing 100 mg/ml penicillin as well as 100 mg/ml stre...

AIMS AND OBJECTIVES Obtaining root coverage has become an important part of periodontal therapy. The aims of this studyare to evaluate the clinical efficacy of acellular dermal matrix graft in the coverage of denuded roots and also to examine the change in the width of keratinized gingiva. MATERIALS AND METHODS A total of 20 sites with more than or equal to 2 mm of recession depth were taken ...

Childhood acellular pertussis vaccines were licensed and implemented in the US in the 1990s following an effort to improve on the safety profile of whole-cell vaccines. However, waning of immunity from acellular vaccines may be driving the recent resurgence of pertussis, raising the need to consider new prevention strategies.

results migration of cells started on the fifth day. as a result of this migration, most cells were located on the surface of the scaffold and formed epiderm-like structure and some penetrated into the scaffold. by day 25, cells which had penetrated into the scaffold had various destinies such as becoming elongated spindle-shaped cells and creating blood vessel-like structures. conclusions adm ...

The efficacy of one-stage artificial dermis and skin grafting was tested in a nude rat model. Reconstruction with artificial dermis is usually a two-stage procedure with 2- to 3-week intermission. If one-stage use of artificial dermis and split-thickness skin grafting are effective, the overall burden on patients and the medical cost will markedly decrease. The graft take rate, contraction rate...

Objective: This study seeks an alternative to acellular dermal matrix in 2-staged breast reconstruction while minimizing cost. It was hypothesized that use of a Gore DualMesh would allow for similar intraoperative tissue expander fill volumes, time to second-stage reconstruction, and number of postoperative fills compared with acellular dermal matrix at only a fraction of the expense. Methods: ...

BACKGROUND The use of acellular dermal matrix has facilitated immediate prosthesis-based breast reconstruction. However, few studies directly compare surgical outcomes following acellular dermal matrix-based reconstruction with two of the most commonly available materials, AlloDerm and FlexHD. Those studies that are available often do not adequately control for the surgeon as a variable. The au...

Although the peripheral nerve has the potential to regenerate after injury, degenerative processes may be essential to promote axonal growth into the denervated nerve. One hypothesis is that the nerve contains growth inhibitors that must be neutralized after injury for optimal regeneration. In the present study, we tested whether degradation of chondroitin sulfate proteoglycan, a known inhibito...

BACKGROUND Because of concern about safety and efficacy, no pertussis vaccine has been included in the vaccination program in Sweden since 1979. To provide data that might permit the reintroduction of a pertussis vaccine, we conducted a placebo-controlled trial of two acellular and one whole-cell pertussis vaccines. METHODS After informed consent was obtained, 9829 children born in 1992 were ...

The use of cultured epithelial autografts for the treatment of extensive burn wounds has become popular in recent years. We examined extensive burn wounds in 14 patients by using a combination of autograft and cultured epithelial autografts developed in Japan (JACE). METHODS We undertook a skin biopsy at 2, 4, and 6 weeks after transplantation with JACE. By using electron microscopy we observ...
