Background: Sickle Cell Anemia (SCA) is the most common monogenic disorder that is inherited as an autosomal recessive pattern. Fetal hemoglobin (HbF) plays a major role in ameliorating clinical severity of the SCA where higher expression of HbF is associated with a reduction in the painful episode and thus reduces the number of hospitalization. The current work aimed to investigate the effect ...

We present a case of asymptomatic, progressive, late occlusion of the left superior cerebellar artery (SCA) and an aneurysm arising from the junction of the SCA and basilar artery after embolization of an adjacent aneurysm arising between the left posterior cerebral artery and the left SCA. The delayed occlusion was associated with reconfiguration of the Guglielmi detachable coils at the neck o...

c-kit is expressed on hematopoietic stem cells and progenitor cells, but not on lymphohematopoietic differentiated cells. Lineage marker-negative, c-kit-positive (Lin-c-kit+) bone marrow cells were fractionated by means of Ly6A/E or Sca-1 expression. Lin-c-kit+Sca-1+ cells, which consisted of 0.08% of bone marrow nucleated cells, did not contain day-8 colony-forming units-spleen (CFU-S), but 80...

â â  a great portion of precipitation in the south western iran falls in the snow formation. surface runoff produced from melting snow has an important role in the recharging ground water, surface and subsurface flows. rapid snowmelt can even cause flooding . since the snowmelt cannot be easily detected from optical satellite images, snow cover area (sca) is derived as an important hydrological...

Sudden cardiac arrest (SCA) is a leading cause of death in the United States. Despite return of spontaneous circulation, patients die due to post-SCA syndrome that includes myocardial dysfunction, brain injury, impaired metabolism, and inflammation. No medications improve SCA survival. Our prior work suggests that optimal Akt activation is critical for cooling protection and SCA recovery. Here,...

[1] A cloud-masked fractional snow-covered area (SCA) product gridded at 1 km was developed from the advanced very high resolution radiometer for the Colorado River and upper Rio Grande basins for 1995–2002. Cloud cover limited SCA retrievals on any given 1-km pixel to on average once per week. There were sufficient cloud-free scenes to map SCA over at least part of the basins up to 21 days per...

OBJECTIVES The aim of the study was to assess the incidence of depression and anxiety symptoms in patients after cardiac arrest (SCA) in relation to patients with a history of myocardial infarction without SCA and in healthy individuals. The analysis of the impact of selected socio-demographic and clinical parameters and duration of SCA on the presence and severity of depression and anxiety sym...

Sudden cardiac arrest (SCA) is a major cause of mortality in North America and other westernized societies, accounting for 10% of all deaths and up to 50% of heart disease–related death.1,2 The condition is characterized by an unexpected cardiovascular collapse due to an underlying cardiac cause.3 This definition, although useful as an intellectual foundation, is challenged by operational trans...

CONTEXT Sickle cell anemia (SCA) is a chronic illness causing progressive deterioration in quality of life. Brain dysfunction may be the most important and least studied problem affecting individuals with this disease. OBJECTIVE To measure neurocognitive dysfunction in neurologically asymptomatic adults with SCA vs healthy control individuals. DESIGN, SETTING, AND PARTICIPANTS Cross-section...
