This study investigated the ability of One-Up Bond alone and mineral trioxide aggregate (MTA), with and without a secondary seal of One-Up Bond or SuperEBA to seal saucer-shaped perforation defects in human molars. Cusps were removed, roots were amputated, and endodontic therapy completed on 40 extracted teeth. A cylindrical hole was made in each tooth from the furcation area to the chamber, in...

KEREM, DAN,GERALD KOOYMAN,JOSEPH P. SCHROEDER,JAMES J. WRIGHT, AND CHARLES M. DRABEK. Hyperbaric oxygen-induced seizure in a marine mammal, the seal. Am. J. Physiol. 222(5) : 13221325. 1972.-A female yearling northern elephant seal, Mirounga angustirostris, and a female yearling harbor seal, Phoca vitulina were subjected to breathing oxygen at a pressure of 4.5 Ata in the restrained unanestheti...

Wafer level packaging could reduce the cost of MEMS based sensors through simplified processing and inexpensive components. A novel vacuum tight seal referred to as the wedge seal method is proposed in this paper. The seal consists of a silicon wedge forced into a pliable material (typically a metal) that is attached to the component wafer. The wedge-seal addresses some of the requirements of m...

The presence of mastitis in bred dairy heifers can adversely affect the development of milkproducing tissues, leading to less than maximal milk production and increased somatic cell counts (SCC) during their first lactation. Use of nonlactating cow therapy has been beneficial in curing existing intramammary infections (IMI), and teat sealants have been beneficial in preventing new IMI from deve...

statement of problem: targis restorations provide good esthetic and clinical success; however, improving marginal accuracy requires further investigations. purpose: the aim of this was to study evaluate the effect of relining on the marginal accuracy of ceromer crowns. material and methods: one ivorine maxillary central incisor was prepared for targis crown. 10 acrylic models were duplicated fr...

BACKGROUND Polar bears (Ursus maritimus) of the Beaufort Sea enter hyperphagia in spring and gain fat reserves to survive periods of low prey availability. We collected information on seals killed by polar bears (n=650) and hunting attempts on ringed seal (Pusa hispida) lairs (n=1396) observed from a helicopter during polar bear mark-recapture studies in the eastern Beaufort Sea in spring in 19...

While high-throughput planar patch-clamp instruments are now established to perform whole-cell recordings for drug screening, the conventional micropipette-based approach remains the gold standard for performing cell-attached single-channel recordings. Generally, planar platforms are not well-suited for such studies due to excess noise resulting from low seal resistances and the use of substrat...
