[The Contralateral Double Transposition Flap]

Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

This protocol describes the tibial neuroma transposition model, which entails a lesion of the tibial nerve with subsequent transposition of the proximal nerve end toward a subcutaneous pretibial or lateral position. Behavioral testing of neuroma pain and plantar hyperalgesia is quantified using Von Frey...

To date, thick tissue defects are typically reconstructed by applying autologous tissue flaps or engineered tissues. In this protocol, we present a new method for engineering vascularized tissue flap bearing an autologous pedicle, to serve as a substitute to autologous flaps.

This protocol describes the surgical technique for harvesting a human perforator flap model based on the deep inferior epigastric artery pedicle, intended for experimental...

This video demonstrates a technique for measuring the contralateral silent period (cSP) using transcranial magnetic stimulation. Position the patient's hand prone and place an electrode on the first dorsal interosseous (FDI) muscle. Then, place a force-measuring device between the thumb and index finger. Identify the primary motor cortex (M1) region of the brain. Maintain a standardized pressure on the force-measuring device and stimulate the M1 region to record the muscle activity, termed the...

The present protocol describes the porcine fascio-cutaneous flap model and its potential use in vascularized composite tissue...
