Does Microwave Exposure at Different Doses in the Pre/Postnatal Period Affect Growing Rat Bone Development?

Effects of pre/postnatal 2.45 GHz continuous wave (CW), Wireless-Fidelity (Wi-Fi) Microwave (MW) irradiation on bone have yet to be well defined. The present study used biochemical and histological methods to investigate effects on bone formation and resorption in the serum and the tibia bone tissues of growing rats exposed to MW irradiation during the pre/postnatal period.

Expression of Cox-2 and Bcl-2 in Paget's disease of the breast.

Background: Paget's disease (PD) is a rare form of intraepithelial adenocarcinoma that involves breast and extramammarian tissues. It is often associated with ductal carcinoma in situ and/or invasive ductal cancer. Molecular pathways that play a role in development of Paget's disease are stil unclear.

The role of insulin-like growth factor 1 in the development of benign and malignant thyroid nodules.

Objective: This study aims to investigate the role of IGF-1 in the development of nodular thyroid disease.

Material And Methods: A total number of 100 consecutive patients operated for nodular thyroid disease in our institution were included in this prospective study. In addition to classical pathological examinations, nodules and extranodular healthy tissues were sampled and immunochemically stained for IGF-1.

The effects of the pretreatment of intravenous high dose methylprednisolone on Na(+)-K(+)/Mg(+2) ATPase and lipid peroxidation and early ultrastructural findings following middle cerebral artery occlusion in the rat.

The sodium-potassium activated and magnesium dependent adenosine-5'-triphosphatase (Na(+)-K(+)/Mg(+2) ATPase EC.3.6.

Intracranial arterial aneurysm complicating Behçet's disease.

Behçet's disease, a rare condition in central Europe but more common in Turkey where it was originally described, is characterized clinically by the presence of a diagnostic triad of oral and genital aphthous ulcers, meningitis, and relapsing iridocyclitis. Vascular lesions including arterial and venous occlusions, arterial aneurysms and varices are one of the common complications of Behçet's disease occur most commonly in the abdominal aorta, femoral arteries and pulmonary arteries. There have been only four reports of aneurysms of cerebral arteries in the literature.

The effect of the treatment of high-dose methylprednisolone on Na(+)-K(+)/Mg(+2) ATPase activity and lipid peroxidation and ultrastructural findings following cerebral contusion in rat.

Background: Although use of corticosteroid in the management of head trauma has caused a great deal of controversy, corticosteroids have long been an adjunct in the management of severe closed head injury. The glucocorticoid steroid methylprednisolone (MP) has been proven to have significant antioxidant effect when administered in an antioxidant-high dose after central nervous system injury.

Methods: The sodium-potassium activated and magnesium dependent adenosine-5'-triphosphatase (Na(+)-K(+)/Mg(+2) ATPase EC.

Effects of naloxone on sodium- and potassium-activated and magnesium-dependent adenosine-5'-triphosphatase activity and lipid peroxidation and early ultrastructural findings after experimental spinal cord injury.

Endorphins have been implicated in the pathophysiology of spinal cord injury. The effect of naloxone on the sodium- and potassium-activated and magnesium-dependent adenosine-5'-triphosphatase (Na(+)-K+/Mg+2 ATPase, EC.3.

Correlation of alterations on Na(+)-K+/Mg+2 ATPase activity, lipid peroxidation and ultrastructural findings following experimental spinal cord injury with and without intravenous methylprednisolone treatment.

The sodium-potassium activated and magnesium dependent adenosine-5'-triphosphatase (Na(+)-K+/Mg+2 ATPase EC 3.6.1.

Giant fusiform aneurysm of the vertebro-basilar artery presenting with stroke.

The authors describe a case of giant fusiform aneurysm of the basilar artery presenting with ischemic symptoms. Angiography and CT revealed vertebro-basilar fusiform aneurysmal dilatation. Fusiform vertebro-basilar aneurysm is associated with various complications particularly brain stem infarction.

Traumatic giant aneurysm of the intracavernous internal carotid artery causing fatal epistaxis: case report.

A patient with a giant intracavernous carotid aneurysm usually has symptoms and signs of a space-occupying lesion, producing one of a variety of types of cavernous sinus syndromes. Epistaxis is an unusual feature in these patients. A patient who noted the onset of repeated arterial epistaxis 2 years after a severe head injury was found to have a traumatic aneurysm of the cavernous portion of internal carotid artery.

The nonsurgical management of a penetrating orbitocranial injury reaching the brain stem: case report.

Penetrating and perforating periorbital puncture wounds by lead pencils are not rare, but ones that reach the brain stem are extremely unusual. We recently treated a patient with of this type of injury. A newly sharpened lead pencil was accidentally introduced through the subconjunctiva at the inner canthus of the right eye.

Surgical treatment of symptomatic subependymoma of the nervous system. Report of five cases.

Subependymomas are uncommon and relatively benign tumors with a distinctive histological appearance. They are generally asymptomatic and most of them are found incidentally at postmortem examination. These tumors are usually located in the fourth and lateral ventricle, and sometimes in the spinal cord.

Colloid cysts of the third ventricle.

Since computerized tomography scanning became available at the Division of Neurosurgery in July, 1979, 13 patients have undergone removal of colloid cysts of the third ventricle by transfrontal or transcallosal routes. Computerized tomography has increased the number of colloid cysts detected in the foramen of Monro during neurological diagnostic workups. The clinical and diagnostic aspects and changing concepts in the treatment of colloid cysts are reviewed.

Cerebellar medulloblastomas in adults.

Between 1981 and 1991, 11 adults over 16 years of age were treated for medulloblastoma at the authors' institutions. These patients were studied retrospectively. The patients were managed uniformly, and the treatment included extensive surgical resections and radiation therapy.

Unilateral hydrocephalus resulting from occlusion of foramen of Monro: a new procedure in the treatment: stereotactic fenestration of the septum pellucidum.

Obstruction at the foramen of Monro resulting in unilateral hydrocephalus is an uncommon entity that may be caused by a wide range of lesions including tumors, vascular malformations, and inflammatory conditions. A case of unilateral hydrocephalus secondary to congenital atresia of the foramen of Monro treated with stereotactic fenestration of the septum pellucidum is presented.

The clinical presentation of intracranial abscesses. A study of seventy-eight cases.

From 1980 through 1991, 78 patients with brain abscess were treated at the Cukurova University School of Medicine Department of Neurosurgery by surgical excision and antimicrobial therapy. Males predominated in all age groups. Although only 17 percent had a predisposing conditions such as local sinus infection, cyanotic heart disease, the majority of the cases had some evidence of a systemic infection such as peripheral leucocytosis and elevated erythrocyte sedimentation rate.

Echo-encephalographic study of ventricular dilatation after subarachnoid hemorrhage, with special reference to the effect of antifibrinolytic treatment.

Echo-encephalographic examinations were performed in 144 patients after subarachnoid hemorrhage. Ninety-three of the patients received antifibrinolytic treatment (AMCA). The width of the third ventricle could be measured in all the patients, and lateral ventricle measurements were obtained in 94 patients.
