BACKGROUND Barium sulfate powder used for radiopacity of experimental blood clots (EBCs) for testing mechanical thrombectomy devices (MTD) has negative effects on EBCs mechanical properties. In vitro and in vivo exploration was performed to determine if the iodine based contrast medium will have less negative effects on the EBCs than barium. MATERIALS AND METHODS Fresh blood from 2 swine was ...

Barium peritonitis is extremely rare, but is difficult to treat and may be life-threatening. Barium suspension leakage from the gastrointestinal tract into the abdominal cavity has a time-dependent and synergistically deleterious effect in patients who have generalized bacterial peritonitis. The severity of barium peritonitis is dependent on the quantity of barium in the abdominal cavity. Bariu...

Explosive increases in skin cancers have been reported in more than 36 million patients with arsenicosis caused by drinking arsenic-polluted well water. This study and previous studies showed high levels of barium as well as arsenic in the well water. However, there have been no reports showing a correlation between barium and cancer. In this study, we examined whether barium (BaCl(2)) may inde...

AIM To review clinical experience with barium appendicitis at a single institution. METHODS A retrospective review of patients admitted with a diagnosis of acute appendicitis, from January 1, 2013 to December 31, 2015 was performed. Age, gender, computed tomography (CT) scan findings if available, past history of barium studies, pathology, and the presence of perforation or the development of...

Müller cells are highly permeable to potassium ions and play a crucial role in maintaining potassium homeostasis in the vertebrate retina. The potassium current found in turtle Müller cells consists of two components: an inwardly rectifying component and a linear, passive component. These currents are insensitive to broadband potassium channel blockers, tetraethylammonium (TEA) and 4-aminopyrid...

background and purpose: fluoride is one of the drinking water contaminants regulated by epa. this ion, in low doses in the mouth reduces tooth decay without health risk and at much higher doses causes health complications and can be toxic. the major sources of exposure to fluoride are drinking water, food, dental products, and pesticides. the biggest contributor to exposure for most people in i...

abstract fluoride (f-) is an essential element for human and some animals. the fluoride concentration in irrigation water is an important index for water quality. the objective of the present study was to determine spatial variability of fluoride in groundwater and soils of some areas in arak plain. therefore, during two seasons, autumn (2007) and the end of spring (2008), 87 and 92 water sampl...
