Epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. Here a case of 58-year-old female presented with left cheek swelling of one-year duration. CT scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. Histological examin...

BACKGROUND Mainstay of post-burn reconstruction is release and split skin grafting. Pedicle flaps are cumbersome to the patient, require multiple procedures and hospitalization. Free flaps are technically demanding and facilities are not universally available. Here we evaluated the local perforator flaps for post-burn reconstruction. METHODS We have used sixteen perforator propellar flaps fo...

A highly efficient Ullmann homocoupling reaction of aryl halides using palladium (II) phosphine-ylide complexes as homogenous pre-catalysts under aerobic conditions has been developed without the need for any chemical co‐reducing agents. The procedure is relatively mild and appears to have broad applicability, being useful for the homocoupling of both electron-deficient and electron-rich aryl h...

Note to readers. What follows are drafts of six chapters of our book in progress, Seductions and Shortcuts: Fallacies in the Cognitive Economy, which is volume 3 of our omnibus work, A Practical Logic of Cognitive Systems, published by Elsevier/NorthHolland. The six chapters that appear here have been drafted as stand-alone pieces, and they have not yet been integrated into a smoothly flowing u...

The current study, setting a two-fold goal, attempted to see whether the preemptive focus on form (FonF) under either planned or unplanned conditions could contribute to increasing lexical diversity in written narratives and, second, to find whether there was a trade-off between the lexical diversity and accuracy. To this end, 32 beginner learners were selected following a Quick Oxford Placemen...

brain hydatid cyst constitutes one of the leading causes of cranial mass in the endemic region, especially among the children. symptoms of the disease are associated with rising of intracranial pressure and focal neurological deficit. surgical excision of the cyst is essential to treatment. here we present a 19 yr-old male livings in ardabil, northwest of iran, referred to neurosurgery clinic i...

Abstract Subduction zones have recurrently formed on Earth. Previous studies have, however, suggested that they are unlikely to start in the interior of a pristine ocean. Instead, seem be more likely form from another pre-existing subduction zone. One widely cited conceptual model new is polarity reversal, resulting shutdown pre-existent zone due arrival buoyant block at trench. However, dynami...

Abstract Off-axis digital holography in the terahertz waves allows three-dimensional visualizations of optically opaque volumetric objects a single exposure and with angular separation zero-order component. Forming tilted reference beam usually requires set mirrors, which can disturb polarization, causing loss contrast fringes at detector. Here we present mirror-less approach 3D-printed transmi...
