The Cyclotron Facil ity at Mount Sinai Medical Center is involved in a program of radionuclide production culminating with the preparation of short-l ived radiopharmaceutical agents requested for cl inical evaluation. The increas ing cl inical "in-house" demand for short-lived, positronemitting radiopharmaceutical compounds has necessitated an efficient production schedule requiring unique modi...

introduction : this investigation evaluates the effects of mineral trioxide aggregate (mta), calcium hydroxide (ch) and calcium enriched mixture (cem) as pulp capping materials on dental pulp tissues. materials and methods: the experimental procedures were performed on eighteen intact dog canine teeth. the pulps were exposed. cavities were randomly filled with cem, mta, or ch followed by glass ...

introduction: the purpose of this study was to compare the sealability of three different commercial types of mineral trioxide aggregate (mta) and calcium enrichment mixture (cem) cement as an experimental root-end filling material. materials and methods: forty-six single rooted teeth were cleaned, shaped, and obturated. the apical 3 mm of each root was resected and root-end cavities with 3 mm ...

for management of a symptomatic maxillary lateral incisor with dull pain on chewing, suppurative sinus tract, defective metal-ceramic crown and iatrogenic internal root resorption, an interdisciplinary approach was taken. two-visit nonsurgical treatment with calcium-enriched mixture (cem) cement, replacement of metal-ceramic crown with all-ceramic crown and corrective periodontal plastic surger...

introduction: the aim of this randomized controlled trial was to compare the radiographic and clinical success rates of direct pulp capping (dpc) using proroot mineral trioxide aggregate (mta) or calcium enriched mixture (cem). methods and materials: a total of 42 symptom-free carious vital primary molars (21 pairs) were selected in this split mouth trial and randomly pulpotomized in two experi...

in all biological systems growth is defined as increase of chemical compounds. bacteria can achieve to balanced growth if they are growing in a medium, which are completely adapted to it. clostridium chauvoei, (clostridium feseri) is an anaerobic, spore forming, motile, and polymorph bacteria, which its size varies from 0.5-1 to 3-8 micron and could be observed as individual bacterium, diplo, a...

Fermentation flavors of corn distillers' grains (CDG) were removed more completely by extraction with hexane:ethanol (82:18 v/v) azeotrope (HEA) than with hexane (H). Desolventizing included air drying followed by heating to 101°C for 10 min with agitated steam injection. Enriched corn-soy-milk (CSM) blends were formulated with up to 10% REAor H-extracted CDG. Color was slightly darker in CSM w...

The high temperature corrosion behavior of sputtered nanocrystalline K38 coating with and without yttrium addition under mixed molten salt film in air was investigated. Accelerated corrosion occurred on the coating without yttrium (Y) addition locally after 60 h exposure at 900 °C, which resulted in negative weight gain in kinetics. A uniform and protective alumina scale formed on surface of th...

We conducted a pilot-scale study at a research facility in southeastern Connecticut to assess the effects of leachfield aeration on removal of nutrients and pathogens from septic system effluent. Treatments consisted of lysimeters periodically aerated to maintain a headspace O(2) concentration of 0.209 mol mol(-1) (AIR) or vented to an adjacent leachfield trench (LEACH) and were replicated thre...
