purpose: to present a case of orbital granular cell tumor, a rare orbital tumor. case report: a 55-year-old woman presented with binocular diplopia and right ocular displacement. the problem had initiated 3 years ago. a firm nontender mass at the region of the right lower lid was visible. orbital ct-scan disclosed a well-defined mass in the inferior right orbit with involvement of the inferior ...

BACKGROUND Glioblastoma multiforme is a highly malignant primary brain tumor that shows marked local aggressiveness, but extracranial spread is not a common occurrence. We present an unusual case of recurrent glioblastoma in 54-year old male that spread through the scull base to the ethmoid and sphenoid sinuses, to the orbita, pterygomaxillar fossa, and to the neck. METHODS A 54-year old male...

The predatory marine gastropod Dicathais orbita has been the subject of a significant amount of biological and chemical research over the past five decades. Natural products research on D. orbita includes the isolation and identification of brominated indoles and choline esters as precursors of Tyrian purple, as well as the synthesis of structural analogues, bioactivity testing, biodistribution...

Myolipoma is a very rare adipocytic tumor occurring most frequently in adults, and usually is located in the retroperitoneum or abdomen. It has been described in the retroperitoneum, spinal cord, orbita, breast, round ligament, subcutaneous tissue, pericardium, rectus sheath of the abdominal wall, and abdominal cavity with attachment to the abdominal wall. Most of these tumors are discovered in...

Five patients were surgically treated for intraorbital foreign body: a 14-year-old girl had a door glass splinter, a 23-year-old man a metallic foreign body--gunshot pellet, a 55-year-old man a splinter from a metallic bar, a 48-year-old patient the splinters of circular saw and 61-year-old man with shot. Two foreign bodies were removed using the Krönlein-Reese-Berk lateral orbitotomy, two othe...

Dicathais orbita is a mollusc of the Muricidae family and is well known for the production of the expensive dye Tyrian purple and its brominated precursors that have anticancer properties, in addition to choline esters with muscle-relaxing properties. However, the biosynthetic pathways that produce these secondary metabolites in D. orbita are not known. Illumina HiSeq 2000 transcriptome sequenc...

The oculomotor periphery was formerly regarded as a simple mechanism executing complex behaviors explicitly specified by innervation. It is now recognized that several fundamental aspects of ocular motility are properties of the extraocular muscles (EOMs) and their associated connective tissue pulleys. The Active Pulley Hypothesis proposes that rectus and inferior oblique EOMs have connective t...
