Evaluation of four elastomeric interocclusal recording materials

Background: The fabrication of dental prosthesis requires the transfer of interocclusal records from patient's mouth to semiadjustable articulators using different kinds of recording media. Any inaccuracy in these interocclusal records leads to occlusal errors in the final prosthesis. This study was conducted to evaluate the dimensional changes occurring in the interocclusal recording material over a given period of time and the material's resistance to compression during the cast mounting on the articulator.     

Production and characterization of monoclonal antibodies to rat plasma kininogen

Five hybridoma cell lines were established that secrete monoclonal antibodies (MAbs) directed against rat plasma low molecular weight plasma kininogen. Two of the secreted antibodies were of the IgG1k isotype. The remaining three were of the IgG1 lambda, IgG2ak and IgMk isotypes, respectively. The dissociation constants (Kd) of these MAbs ranged from 0.58 X 10(-9) M to 5.4 X 10(-9) M. At least two distinct epitopes on the rat plasma kininogen were recognized by these MAbs. Further characterization of the MAbs showed that four MAbs cross-reacted strongly with kininogen from the Murphy-Sturm lymphosarcoma (MSLS) tumor while one of the MAbs cross-reacted weakly with MSLS tumor kininogen.     

Placenta membranacea, previa and accreta. A case report.

A case of placenta membranacea, previa and accreta was managed conservatively and resulted in delivery of a mature fetus. The diagnosis of placenta membranacea and previa was obtained with ultrasound. The placenta previa and accreta necessitated a cesarean delivery and hysterectomy.
