Vitiligo affects approximately 2% of the worldwide population regardless of race, ethnic background or gender. When the medical methods are not successful, surgical procedures may be considered with the aim of placing a new source of pigment cells to reinitiate melanogenesis within the affected areas. This study was conducted to evaluate the efficacy of combining punch grafting followed by PUVA...

Keloids and hypertrophic scars are basically an overabundance of fibrosis in cutaneous healing process. Unfortunately, keloids are only found in human beings. So far no successful animal model of keloid has been reported. Objectives: To produce an animal model of keloid. Main Outcome Measure: Animal model of keloid. Design: Prospective quasiexperimental trial. Setting: Department of Pathology a...

Understanding a joke relies on semantic, mnemonic, inferential, and emotional contributions from multiple brain areas. Anatomically constrained magnetoencephalography (aMEG) combining high-density whole-head MEG with anatomical magnetic resonance imaging allowed us to estimate where the humor-specific brain activations occur and to understand their temporal sequence. Punch lines provided either...

OBJECTIVES To describe a novel surgical technique for complete excision of a rectovaginal fistula tract using a disposable biopsy punch during a transvaginal rectovaginal fistula repair and to present our initial surgical experience. METHODS Description of 4 cases of simple rectovaginal fistulas and an innovative surgical technique for the complete excision of the fistula tract using a dispos...

The stainless steel bipolar plate has received much attention due to the cost of graphite bipolar plates. Since the micro-channel of bipolar plates plays the role of fuel flow field, electric connector and fuel sealing, an investigation of the deep drawing process for stainless steel micro-channel arrays is reported in this work. The updated Lagrangian formulation, degenerated shell finite elem...

The trend towards miniaturisation of metallic mass production components combined with increased component functionality is still unbroken. Manufacturing these components by forming and blanking offers economical and ecological advantages combined with the needed accuracy. The complexity of producing tools with geometries below 50 μm by conventional manufacturing methods becomes disproportional...

BACKGROUND Dermoscopy is a simple-to-use, in vivo method for the diagnosis of malignant melanoma and the differential diagnosis of pigmented skin lesions. It uses an immersion technique and optical magnification to visualize structures not visible to the naked eye. The anatomoclinical correlation of dermoscopic with histopathologic findings is important, and while many articles have described d...
