BACKGROUND AND PURPOSE Ischemic injury to the brain is a common complication of SCA. To better understand the neurologic impact of SCA, TBSS were applied to DTI data to investigate white matter injuries in pediatric patients with SCA. MATERIALS AND METHODS TBSS comparisons of a range of anisotropy and diffusion measures were carried out between age- and background-matched population groups: p...

OBJECTIVES The PAREPET (Prediction of ARrhythmic Events with Positron Emission Tomography) study sought to test the hypothesis that quantifying inhomogeneity in myocardial sympathetic innervation could identify patients at highest risk for sudden cardiac arrest (SCA). BACKGROUND Left ventricular ejection fraction (LVEF) is the only parameter identifying patients at risk of SCA who benefit fro...

Murine bronchioalveolar stem cells play a key role in pulmonary epithelial maintenance and repair but their molecular profile is poorly described so far. In this study, we used antibodies directed against Sca-1 and CD34, two markers originally ascribed to pulmonary cells harboring regenerative potential, to isolate single putative stem cells from murine lung tissue. The mean detection rate of p...

Spinocerebellar ataxia type 36 (SCA36) is a new SCA subtype recently reported in Japanese and Spanish pedigrees. To assess the frequency and clinical characteristics of SCA36 in patients from Mainland China, we combined the repeat-primed polymerase chain reaction method and Southern blot analysis to detect the GGCCTG hexanucleotide repeats of NOP56 in 364 probands with SCA, 126 probands with he...

The fluid distribution as a function of height in transition zones is often very complex. This may be due to movement of water-oil contact, tilting of the reservoir at some point in time, leak of fluid out of the reservoir zone or complex inflow during secondary migration. The resultant fluid distribution seen in saturation logs may be difficult to model. In this paper we address the changes in...

Low resistivity in argillaceous sandstone reservoirs may be attributed either to the effect of microporosity, or to specific effects due to clays and/or to conducting minerals. In the frame of a study on pore lining chlorite bearing sandstones, from different hydrocarbon reservoirs, measurements of cation exchange capacities and specific surface areas have been performed, on whole rocks as well...

BACKGROUND Recent reports indicate that specific left ventricular (LV) geometric patterns predict recurrent ventricular arrhythmias in patients with implantable cardioverter-defibrillators and reduced left ventricular ejection fraction (LVEF). However, this relationship has not been evaluated among patients at risk of sudden cardiac arrest (SCA) in the general population. METHODS AND RESULTS ...

BACKGROUND AND PURPOSE A mathematical model has previously been introduced to estimate noninvasively intracranial pressure (nICP). In the present multicenter study, we investigated the ability of model to adapt to the state of cerebral autoregulation (SCA). This modification was intended to improve the quality of nICP estimation and noninvasive assessment of pressure reactivity of the cerebrova...

Although somatic stem cells have been reported to exist in various adult organs, there have been few reports concerning stem cells in the heart. We here demonstrate that Sca-1-positive (Sca-1+) cells in adult hearts have some of the features of stem cells. Sca-1+ cells were isolated from adult murine hearts by a magnetic cell sorting system and cultured on gelatin-coated dishes. A fraction of S...

Hemoglobinopathies are the most common genetic disorders in the world and include sickle cell anemia (SCA), which is a public health problem in Brazil. Nevertheless, the disease is highly unknown among health professionals, and delayed diagnosis constitutes an important cause of concern for caretakers of SCA patients. The purpose of this study was to compare the clinical and laboratory history ...
