BACKGROUND AND PURPOSE The ischemic core and penumbra have not been thoroughly characterized after acute cerebral thromboembolic occlusion in humans. Differentiation between areas of potentially viable and irreversibly injured ischemic tissue may facilitate assessment and treatment of stroke patients. METHODS Cerebral blood flow (CBF) was measured in 20 patients with acute middle cerebral art...

OBJECTIVES Pericardial fat as a visceral fat depot may be involved in the pathogenesis of coronary atherosclerosis. To gain evidence for that concept we sought to investigate the relation of pericardial fat volumes to risk factors, serum adiponectin levels, inflammatory biomarkers, and the quantity and morphology of coronary atherosclerosis. METHODS AND RESULTS Using Dual source CT angiograph...

in order to design and manufacturing some postharvest equipment, determination of some hydrodynamic properties of crops are necessary. the quality of products in global and local markets can be increased by applying these properties and receive economical benefits. for these purpose, two local varieties of apples in the east azerbaijan province, iran(asheghi and gare yapraq)were selected.ashegh...

BACKGROUND To investigate the feasibility and benefits of a modified adaptive radiotherapy (ART) by replanning in the initial CT (iCT) with new contours from a repeat CT (rCT) based on CT-CT image fusion for nasopharyngeal cancer (NPC) patients underwent volumetric modulated arc radiotherapy (VMAT). MATERIALS AND METHODS Nine NPC patients underwent VMAT treatment with a rCT at 23rd fraction w...

BACKGROUND AND PURPOSE The aim of this study was to determine the 30-day mortality and morbidity of intracerebral hemorrhage in a large metropolitan population and to determine the most important predictors of 30-day outcome. METHODS We reviewed the medical records and computed tomographic films for all cases of spontaneous intracerebral hemorrhage in Greater Cincinnati during 1988. Independe...

The nasal valve region plays a key role in nasal breathing. In the international literature, a variety of techniques have been described to rectify nasal valve compromise, but based on the present evidence it is impossible to counsel a patient as to which technique is most effective. The aim of this study was to evaluate the results of surgery of the nasal valve through a hemitransfixion incisi...

Maize storage proteins synthesized in oocytes were compartmentalized in membrane vesicles because they were resistant to hydrolysis by protease, unless detergent was present. The site of storage protein deposition within the oocyte was determined by subcellular fractionation. Optimal separation of oocyte membranes and organelles was obtained when EDTA and high concentrations of NaCl were includ...

BACKGROUND Air-displacement plethysmography (ADP) is becoming a popular method to assess body composition. Several studies have shown certain types of clothing can affect measurements of body density, however no study has specifically investigated the effect of cotton gym shorts and spandex bicycle shorts on body density. METHODS Thirty-seven males (23.0 +/- 3.2 yr., 177.3 +/- 5.4 cm., 74.8 +...

The aim of this study was to perform for the first time the intracranial volumetric analysis of cerebrospinal fluid (CSF) and brain parenchyma in the supratentorial and infratentorial space in a 30-year-old female patient with hydranencephaly and macrocephaly. A head scan performed using a 3T magnetic resonance was followed by manual segmentation of the brain parenchyma and CSF on T2 coronal br...

In the present work, essential oil has been obtained by Clevenger-type hydrodestillation from grounded curcuma rhizome (Rhizoma Curcumae) (Turkey) with hydromodulus 1:5 m/V during 180 minutes. The qualitative and quantitative composition of the oil was determined by GC-MS and GC-FID spectrometry. The antioxidant activity of the obtained oil was determined using DPPH assay just after adding DPPH...
