background: brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. serum agglutination test (sat) is the most-widely used test for diagnosing brucellosis. the enzyme linked immunosorbent assay (elisa) can also determine specific antibody classes against brucella. it is a sensitive, simple and rapid test, which coul...

conclusions based on 8.2 mm cut-off point could differentiate 83% periapical granulomas and 79% radicular cysts from radiography images. background the distinction between radicular cysts and apical granulomas is important in treatment decision. objectives the current study aimed to differentiate these two lesions based on radiography images. results average size of radiography in periapical gr...

A point p of a topological space X is a cut point of X if X − {p} is disconnected. Further, if X −{p} has precisely m components for some natural number m ≥ 2 we will say that p has cut point order m. If each point y of a connected space Y is a cut point of Y , we will say that Y is a cut point space. Herein we construct a space S so that S is a connected Hausdorff space and each point of S is ...
