The collagen gel contraction assay is an in vitro model of wound contraction. It is performed using the dermal equivalent model, which consists of dermal fibroblasts seeded into a collagen gel. [ 1 ]
In one case, however, a particular type of collagen graft led to significant delay of wound closure. [6] Careful study of histology samples revealed that grafts that delayed wound closure induced the synthesis of new dermis de novo at the injury site, instead of forming scar, which is the normal outcome of the spontaneous wound healing response.
Tough bundles of collagen called collagen fibers are a major component of the extracellular matrix that supports most tissues and gives cells structure from the outside, but collagen is also found inside certain cells. Collagen has great tensile strength, and is the main component of fascia, cartilage, ligaments, tendons, bone and skin.
Silicone gel sheet (beige) Silicone gel sheeting (SGS) has been an effective reduction and preventive scar therapy since 1980. [ 1 ] It was first discovered to be used in treating scars by Perkins in Australia and New Zealand, and first discussed in the thesis of Karen Quinn, a British biomedical engineering student, in 1985.
Medical simulation, or more broadly, healthcare simulation, is a branch of simulation related to education and training in medical fields of various industries. Simulations can be held in the classroom, in situational environments, or in spaces built specifically for simulation practice. [ 1 ]
A pair of Saturday NFL games drew a larger viewing audience than college football for the rollout of the sport's 12-team playoff. The playoff game between SMU and Penn State averaged 6.4 million ...
Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]
The Philadelphia Eagles have been one of the NFL’s hottest teams. Bettors know all about it. The Eagles have won eight in a row since their bye and they’ve been nearly as good against the spread.
