OBJECTIVE To evaluate the effect of stent based methotrexate delivery on neointimal hyperplasia. METHODS Stainless steel coronary stents and biological polymer coated (SAE) stents were randomly implanted in coronary arteries of pigs with a stent to artery ratio of 1.1:1. The pigs were killed after five days (10 stents) or four weeks (20 stents). Second, stainless steel coronary stents were di...

BACKGROUND The incidence of asbestos-induced human cancers is increasing worldwide, and considerable evidence suggests that reactive oxygen species (ROS) are important mediators of these diseases. Our previous studies suggested that mitochondria might be involved in the initiation of oxidative stress in asbestos-exposed mammalian cells. OBJECTIVE We investigated whether mitochondria are a pot...

BACKGROUND Reduced arterial elasticity and endothelial dysfunction both may indicate early cardiovascular (CV) disease in young adults. Pulse waveform analysis estimates large (LAE) and small (SAE) artery elasticity noninvasively. We assessed the associations between LAE and SAE and markers of endothelial dysfunction and CV risk factors. METHODS The Coronary Artery Risk Development in Young A...

Objectives: Saffron is the stigma of Crocus sativus L., which has the potentials to play a role in the treatment of many diseases. Although many researches are now going on this precious spice, there are few data on saffron safety in human, especially in patients with chronic mental illnesses. This study aimed to evaluate the short-term safety and tolerability of both saffron and crocin (its ma...

sae is a two-component signal transduction system in Staphylococcus aureus that regulates the expression of many virulence factors at the transcriptional level and appears to act synergistically with agr in some cases. In this study, the interactions between sae and agr have been characterized in some detail. It was found that the sae locus is larger and more complex than originally envisioned,...

PURPOSE Acute internal hemorrhage is an occasionally life-threatening complication in pediatric cancer patients. Many therapeutic approaches have been used to control bleeding with various degrees of success. In this study, we evaluated the efficacy of selective internal iliac artery embolization for controlling acute intractable bleeding in children with malignancies. METHODS We retrospectiv...

BACKGROUND Hemorrhage after blunt trauma is a major contributor to death after trauma. In the abdomen, an injured spleen is the most frequent cause of major bleeding. Splenectomy is historically the treatment of choice. In 2007, non-operative management (NOM) with splenic artery embolization (SAE) was introduced in our institution. The indication for SAE is hemodynamically stable patients with ...

Because of recent papers suggesting that subcortical arteriosclerotic encephalopathy (SAE) (Binswanger's disease) is more common than historically assumed, this investigation was initiated to assess the frequency of SAE, to gauge the reliability of CT in making this diagnosis, and to assess the strength of the correlation between SAE and arterial hypertension. Of 202 autopsied patients in a 17-...

OBJECTIVE To test the hypothesis that there is no difference in the stability and resistance to orthodontic forces of immediately loaded sandblasted and acid-etched (SAE) mini-implants and those of machined-surface implants of the same size and shape. MATERIALS AND METHODS Two types of mini-implants were used in the tibiae of 44 rabbits; some had an SAE surface and some had machined surfaces....
