Health risk for well drinking water is a worldwide problem. Our recent studies showed increased toxicity by exposure to barium alone (≤700 µg/L) and coexposure to barium (137 µg/L) and arsenic (225 µg/L). The present edition of WHO health-based guidelines for drinking water revised in 2011 has maintained the values of arsenic (10 µg/L) and barium (700 µg/L), but not elements such as manganese, ...
This study aimed to develop and evaluate barium and calcium microcapsules as candidates for scaffolding in artificial dermal papilla. Dermal papilla cells (DPCs) were isolated and cultured by one-step collagenase treatment. The DPC-Ba and DPC-Ca microcapsules were prepared by using a specially designed, high-voltage, electric-field droplet generator. Selected microcapsules were assessed for lon...
BACKGROUND For many years, double contrast barium enema has been an effective way to evaluate the large bowel. With the development of the colonoscope, the role of barium enema has been questioned. However it is still useful in investigating patients with colorectal symptoms especially in the developing world where colonoscopy is widely unavailable and fraught with challenges in completely eval...
OBJECTIVE To assess the routine use of barium swallow study in patients with chronic cough. METHODS Between October of 2011 and March of 2012, 95 consecutive patients submitted to chest X-ray due to chronic cough (duration > 8 weeks) were included in the study. For study purposes, additional images were obtained immediately after the oral administration of 5 mL of a 5% barium sulfate suspensi...
*Financial sponsoring – none Contrast barium enema is a 60-200% solution of barium sulphate, administered rectally. It is used not only in the diagnostics of colorectal diseases, but also as a therapeutic option in case of intussusception or treatment of lower gastrointestinal tract bleeding. The latter indication raises most controversies amongst surgeons. Opponents argue that 7080% of cases o...
Rectal bleeding often heralds serious colonic disease. The literature suggests that colonoscopy is superior to barium enema plus sigmoidoscopy, although no good comparative studies exist. Seventy one patients with overt rectal bleeding had prospectively flexible sigmoidoscopy, double contrast barium enema and colonoscopy completed independently. Against the gold standard, the sensitivity and sp...
nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a ba:fe molar ratio of 1:10. the effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. the results revealed that the formation of barium hexaferritefine particles is influenced by mo...
