An examination of 1732 conventionally treated maxillary molars was made in an attempt to determine the percentage of MB2 canals that could be located routinely. The teeth examined were 1096 first molars, 611 second molars, and 25 third molars. The results were recorded on a modified computer program over an 8-yr period of time. An interesting trend was noted. The MB2 canal was found in 802 (73....

Three distinct molecular subsets with different structures and alloantigenic determinants were identified in human Ia antigens from cells of an HLA-Dw7 homozygous cell line. The subsets carried DR7 specificity, BR4X7 supertypic specificity and MB2 supertypic specificity, respectively, and were immunospecifically separated by the use of operationally monospecific alloantisera. These specificitie...

The automated (CK)MB1,2/MM1,2,3 isoform measurement, based on electrophoresis, has been simplified to the point that it has become possible to perform this analysis on a 24-h routine basis. We studied analytical aspects of this analysis and its clinical relevance in relation to other biochemical markers (CK total, CKMB activity, CKMB mass, myoglobin, Troponin I and Troponin T) in patients with ...

Because of a recent whole genome duplication, the hypoxia-tolerant common carp and goldfish are the only vertebrates known to possess two myoglobin (Mb) paralogs. One of these, Mb1, occurs in oxidative muscle but also in several other tissues, including capillary endothelial cells, whereas the other, Mb2, is a unique isoform specific to brain neurons. To help understand the functional roles of ...

conclusion the determination of the presence of mb2 in the maxillary first molars may be carried out using cbct scans. if the ∠mdp was 91 degrees or greater, there was considered to be a higher probability that mb2 canals would be found in the endodontic cavity. due to the positive correlation between the ∠mdp and the ∠mdmb2, the localization of mb2 canals may be easily performed in relation to...

j Y a'med to assess the reliability of a panel of antibodies in ' perent'a' diagnosis of lymphomas and germ cell tumours, n n'f ant'b?dies commonly used in lymphoma panels ^ CA, L26, MBl, MB2, CD21, UCHL-1, CD3, and CD30), the germ cell tumour marker, placental alkaline phosphatase and EMA were applied to paraffin sections of 16 seminomas, 15 teratomas and one mixed tumour. Reactivity was demon...

A sample of 308 extracted human permanent maxillary first molars from an Indonesian population was randomly selected. A rhomboid access cavity was made in all teeth in anticipation of identifying a second mesiobuccal canal (MB2). Ultrasonic tips were used to open the subpulpal groove to locate the second canal in the mesiobuccal root. Dentin was carefully removed from the trifurcation area at t...

Ultrasound and photoacoustic imaging are highly complementary modalities since both use ultrasonic detection for operation. Increasingly, photoacoustic and ultrasound have been integrated in terms of hardware instrumentation. To generate a broadly accessible dual-modality contrast agent, we generated microbubbles (a standard ultrasound contrast agent) in a solution of methylene blue (a standard...
