BACKGROUND The development of a gonorrhea vaccine is challenged by the lack of correlates of protection. The antigenically variable neisserial opacity (Opa) proteins are expressed during infection and have a semivariable (SV) and highly conserved (4L) loop that could be targeted in a vaccine. Here we compared antibodies to linear (Ab(linear)) and cyclic (Ab(cyclic)) peptides that correspond to ...

AIM To evaluate different dental tissues (pulp, dentin, and cement) as sources of DNA for forensic analysis. METHODS A total of 20 teeth were obtained from unidentified bodies buried at the Central Cemetary in Bogotá in 1995 and exhumed in 2000. The tissues from three teeth obtained after surgery were used as controls. The pulp cavity was exposed after cutting each tooth with a high-speed han...

in order to survey the evolutionary history and impact of historical events on the genetic structure of iranian people, the hv2 region of 141 mtdna sequences related to six iranian populations were analyzed. slight and non-significant fst distances among the central-western persian speaking populations of iran testify to the common origin of these populations from one proto-population. mismatch...

Present study describes the results of an efficient protocol for the isolation of good quality DNA from human saliva. The protocol includes collection of saliva in sterile specimen tubes, followed by the cell lysis. After formation of cell lysate, proteins wereextracted by phenol chloroform treatment for purification of DNA. The purified DNA was precipitated by adding equal volume of isopropano...
