Plastic wound retractors as bacteriological barriers in gastrointestinal surgery: a prospective multi-institutional trial.
BACKGROUND Surgical site infection remains a significant problem, and peri-operative strategies to reduce wound exposure to bacteria are needed urgently. Plastic ring wound retractors, used to gain access to the abdominal cavity, may shield the incision site from bacteria. AIM To evaluate exposure of the surgical incision site to bacteria using a plastic ring wound retractor in gastrointestin...

متن کاملAutomatic Feature extraction in Wound Healing Videos
We present an automatic feature extraction procedure for the analysis of time-lapse light microscopy wound healing videos, which are used to record the closure of in vitro wounds made in confluent monolayers of cultured epithelial cells under a variety of experimental conditions. Because of the size and complexity of the moving image data type, and hence the length of time required to undertake...
متن کاملFunctional implications of supercontracting muscle in the chameleon tongue retractors.
Chameleons capture prey items using a ballistic tongue projection mechanism that is unique among lizards. During prey capture, the tongue can be projected up to two full body lengths and may extend up to 600 % of its resting length. Being ambush predators, chameleons eat infrequently and take relatively large prey. The extreme tongue elongation (sixfold) and the need to be able to retract fairl...
متن کاملMicroscopic Characteristics of Lower Eyelid Retractors in Koreans
PURPOSE To identify the microscopic characteristics of lower eyelid retractors in Korean individuals and to elucidate age-related changes in lower eyelid retractors. METHODS Eighteen Korean lower eyelids from formalin-fixed cadavers were stained with Masson's trichrome. Specimens were divided into two groups based on age at death (group A, ≤65 years; group B, >65 years), and the microscopic f...
