purpose: to report a case of metastatic tumor to the right upper eyelid originating from a lung adenocarcinoma without any systemic signs. case report: a 68-year-old man had a two-month history of painless swelling in the right upper eyelid. the tumor slowly grew. two years before his presentation, he had received chemotherapy for lung cancer for one year. systemic and ocular examinations were ...

trauma is the most common reason in 1-34 years olds. in patient with multiple traumas, the head is the most common involved part. the importance of computed tomography (ct scan) in diagnosis of brain trauma is well established and ct of the brain is a choice method. finding lesion in brain traumatic patient is very important so goal of this study is finding of brain ct scan in traumatic patient...

introduction: the aim of this study was to identify the reasons for failure in clinical, radiographic, and histopathologic diagnoses as well as their interactions with each other. methods: personal information and lesion characteristics of 51 patients with central or peripheral exophytic lesions were collected in mashhad dental school. specialists determined clinical and radiographic diagnoses ...

both urban and rural cutaneous leishmaniasis (cl) are endemic in different parts of iran and have long been recognized in most provinces. however, there is no report of endemicity of cl in rural areas of kashan, 200 km north of isfahan and 260 km south of tehran, iran. to our knowledge, this is the first report of outbreak of cutaneous leishmaniasis in this area. to study and identify the natur...

cone beam computed tomography is a useful technique for imaging the craniofacial lesions. it produces more realistic images that facilitate interpretation. juvenile ossifying fibroma (jof) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. mandibular lesions can be seen in 10% of the cases.in both jaws, it has a predilection for the...

abstractintroduction: parkinson's disease (pd) is a neuropathological disorder involving the degeneration of dopaminergic neurons in the substantia nigra, with the subsequent loss of their terminals in the striatum. quercetin, a natural flavonoid, is a strong antioxidant and radical scavenger. therefore, its neuroprotective effect in a model of parkinson’s disease in rat was evaluated.meth...

we determined the knowledge of parents of 200 pediatric patients for bacterial endocarditis prophylaxis (bep ), using an eight question survey pertaining to their knowledge of their child's cardiac disease, medications, and bep. the patient's cardiac lesion and current medications were verified at the time of admission for diagnostic or interventional cardiac catheterization. each pat...

Diastereomeric 8,5'-cyclopurine 2'-deoxynucleosides, containing a covalent bond between the deoxyribose and the purine base, represent an important class of DNA damage induced by ionizing radiation. The 8,5'-cyclo-2'-deoxyguanosine lesion (cdG) has been recently reported to be a strong block of replication and highly mutagenic in Escherichia coli. The 8,5'-cyclopurine-2'-deoxyriboses are suspec...

BACKGROUND AND PURPOSE Calcium channel blockers reduce edema due to cerebral ischemia, but little is known about their usefulness in hemorrhage. Therefore, we studied the effect of the calcium channel blocker (S)-emopamil in collagenase-induced hemorrhage. METHODS Adult rats had hemorrhagic necrosis induced by the intracerebral injection of 0.4 U of bacterial collagenase. Six groups of rats w...

The first generation of solar neutrino experiments narrowed the allowed flavor mixing and mass parameter solutions (for νe ↔ νx) to a few isolated regions of sin 2 2θ − ∆M 2 parameter space. Recently, the Small Mixing Angle (SMA) solution (sin 2 2θ ∼ 10 −3 → 10 −2 and ∆M 2 ∼ 10 −5 eV 2), and the " just so " (∆M 2 < 10 −9 eV 2) solutions have been disfavored by results from Super-Kamiokande 1 2 ...
