Particle condensates in general magnetic mirror geometries high-temperature plasmas may be caused by a discrete resonance with thermal ion-acoustic background noise near points. The breaks the bounce symmetry, temporally locking particles to resonant wavelength. relevant correlation lengths are Debye length parallel direction and ion gyroradius perpendicular direction.

Photo-acoustic Tomography (PAT) and Thermo-acoustic Tomography (TAT) are medical imaging modalities that combine the high contrast of radiative properties of tissues with the high resolution of ultrasound. In both modalities, a first step concerns the reconstruction of the radiation-induced source of ultrasound. Transient Elastography (TE) and Magnetic Resonance Elastography (MRE) combine the h...

we report a rare genetic disorder case of neuroacanthocytosis with clinical profile (oro-lingual-facial abnormal involuntary movements, neuropathy) and typical magnetic resonance findings (cerebral atrophy, bilateral caudate nuclei atrophy with dilated anterior horns of the lateral ventricles), positive family history in his brother and acanthocytosis in peripheral blood smear.

abstract radionuclide cisternography (rnc) is of potential value in pointing out the sites of cerebrospinal fluid (csf) leakage in patients with spontaneous intracranial hypotension (sih). in the current report, we present two patients who underwent rnc for suspected csf leakage. both patients underwent magnetic resonance imaging (mri) and rnc for evaluation. we describe a simple method to incr...

background: distinction between radiation necrosis and recurrence of intraparenchymal tumors is necessary to select the appropriate treatment, but it is often difficult based on imaging features alone. we developed an algorithm for analyzing magnetic resonance spectroscopy (mrs) findings and studied its accuracy in differentiation between radiation necrosis and tumor recurrence. m e t hod s :  ...

central nervous system involvement arising from schistosomiasis is uncommon. it may be produced most fre­quently by schistosoma japonicum infection, but reports of s. mansoni presenting as an intracerebral mass lesion are particularly rare. the authors describe the case of a 35-year-old woman with a 3-month history of partial epilep­tic seizures and head­aches. she immigrated to egypt 4 years a...

spinal epidural lipomatosis is a rare condition which is described as the accumulation of fat in the extradural territory and often causes dural impingement. spinal epidural lipomatosis has been implicated in causing a variety of neurologic impairments ranging from back pain, radiculopathy, claudication, myelopathy or even cauda equina syndrome. we report a 46-year-old female with obesity and a...

abstract primary cardiac tumors are rare in all ages. their reported prevalence ranges from 0.001 to 0.03 percent in autopsy series. 25 percent of primary cardiac tumors are considered to be malignant, the majority of which are sarcomas. on account of the late presentation of symptoms in malignant heart masses, finding locally infiltrative tumors or systemically widespread cases at initial pres...

a 64-year-old female with history of previous aortoiliac occlusion and aortoiliac bypass operation four months ago presented with dyspnea, ascites and leg edema. she has been suffering from bloody diarrhea since two weeks earlier. laboratory data showed important eosinophilia and stool examination was positive for strongyloides stercoralis. patient had clinical signs of heart failure. a cardiac...
