Schenkein H, Bradley J, Purkall D
J Dent Res . 2013 Jul; 92(9):814-8. PMID: 23857644
β2-glycoprotein I (β2GPI)-dependent anticardiolipin autoantibodies (aCl) are associated with thrombosis and fetal loss. Some microbial pathogens can induce pathogenic antibodies cross-reactive with β2GPI. Sera from a significant percentage of periodontitis...

Kikuchi T, El Shikh M, El Sayed R, Purkall D, Elaasser M, Sarraf A, et al.
J Periodontal Res . 2010 Jun; 45(6):720-30. PMID: 20572914
Background And Objective: Epidemiological and animal studies suggest that periodontal infections increase atherosclerosis risk. Periodontitis patients have elevated levels of anti-phosphorylcholine (anti-PC) reactive not only with numerous periodontal organisms but...

Kikuchi T, Willis D, Liu M, Purkall D, Sukumar S, Barbour S, et al.
J Dent Res . 2005 Aug; 84(9):858-62. PMID: 16109998
Patients with localized aggressive periodontitis have type-1 cytokines in gingival crevicular fluid and high titers of IFN-gamma-dependent IgG2 reactive with P. gingivalis in gingival crevicular fluid and serum. Localized aggressive...

Scott P, Purkall D, Ruddy S
J Immunol Methods . 1997 Mar; 202(2):213-6. PMID: 9107310
Thrombospondin (TSP), a platelet glycoprotein, was purified from platelet supernatants applied sequentially to Sepharose 4B and heparin-agarose affinity columns. This TSP inhibited alternative pathway activity in serum as assessed by...

Whiteman L, Purkall D, Ruddy S
Eur J Immunol . 1995 May; 25(5):1481-4. PMID: 7774654
Activation of the alternative complement pathway of serum produces complexes of properdin (P) and C3 as measured in a double antibody enzyme-linked immunosorbent assay. When purified from serum, these complexes...

Whiteman L, Purkall D, Ruddy S
J Immunol . 1991 Aug; 147(4):1344-51. PMID: 1869827
An ELISA using antibody to properdin (P), followed by antibody to C3 to detect complexes of P with C3 (P-C3), detected low levels of P-C3 complexes in human serum and...

Gelfand E, Rao C, Minta J, Ham T, Purkall D, Ruddy S
Am J Med . 1987 Mar; 82(3 Spec No):671-5. PMID: 3826129
A nine-year-old white boy with recurrent pneumococcal bacteremia is described. His serum had no hemolytic activity in either the classic or alternative complement pathways. Absence of classic pathway activity was...
