osteochondroma or exostosis is the most common benign bone tumor, and occurring frequently in the proximal humerus, tibia, and distal femur. it rarely affects talus. osteochondroma of talus is a very rare etiology of tarsal tunnel syndrome (tts). we report a rare case of extensive osteochondroma of the talus in a 60 year old female presenting with multiple swellings around the ankle and symptom...

In forest canopies, it is common to perform leaf-level gas-exchange measurements on recently excised branches, often without testing for excision-related biases. We conducted a formal test of excision effects using from cut and uncut canopy branches three deciduous hardwoods - sugar maple (Acer saccharum Marsh.), tulip poplar (Liriodendron tulipifera L.), white oak (Quercus alba L.). Across all...

introduction: lasers have made tremendous progress in the field of dentistry and have turned out to be crucial in oral surgery as collateral approach for soft tissue surgery. this rapid progress can be attributed to the fact that lasers allow efficient execution of soft tissue procedures with excellent hemostasis and field visibility. when matched to scalpel, electrocautery or high frequency de...

The ReCell system (Avita Medical) is a cell culture product that allows the immediate processing of a small split-thickness skin biopsy to produce a complete population of cells including keratinocytes, melanocytes, Langerhans cells and fibroblasts. This series is the first to highlight the reconstructive applications of ReCell following ablative skin cancer surgery. The ReCell system was utili...

The XPA (Xeroderma pigmentosum A) protein is one of the six core factors of the human nucleotide excision repair system. In this study we show that XPA is a rate-limiting factor in all human cell lines tested, including a normal human fibroblast cell line. The level of XPA is controlled at the transcriptional level by the molecular circadian clock and at the post-translational level by a HECT d...

Dermatofibrosarcoma protuberans (DFSP) is a rare tumor of dermal fibroblast. Diagnosis poses challenge to every surgeon. Its propensity recur can be attributed its characteristic finger-like projections, misdiagnosis, and incomplete excision. Wide local excision with adequate margins may lead functional defects cosmetic blemishes. Most cases undergoing second surgery warrants reconstructive pro...
