Protection to Tomato Wilt Disease Conferred by the Nonpathogen <i>Fusarium oxysporum</i> Fo47 is More Effective Than that Conferred by Avirulent Strains

Myocardial protection conferred by electromagnetic fields.

BACKGROUND It has been reported that electromagnetic (EM) fields induce stress proteins in vitro. These proteins have been shown to be important in recovery from ischemia/reperfusion. It was, therefore, hypothesized that EM fields could activate stress responses in vivo and protect myocardial tissue during anoxia. METHODS AND RESULTS Chick embryos were exposed to 4-, 6-, 8-, and 10- microT an...

The immunity conferred by anthrax avirulent uncapsulated live vaccine following different methods (intradermal and subcutaneous) of vaccination

Genetic protection against hepatitis B virus conferred by CCR5Delta32: Evidence that CCR5 contributes to viral persistence.

Recovery from acute hepatitis B virus (HBV) infection requires a broad, vigorous T-cell response, which is enhanced in mice when chemokine receptor 5 (CCR5) is missing. To test the hypothesis that production of a nonfunctional CCR5 (CCR5Delta32 [a functionally null allele containing a 32-bp deletion]) increases the likelihood of recovery from hepatitis B in humans, we studied 526 persons from t...

Ancient origin of pathogen recognition specificity conferred by the tomato disease resistance gene Pto.

We have investigated the origin of the Pto disease resistance (R) gene that was previously identified in the wild tomato species Lycopersicon pimpinellifolium and isolated by map-based cloning. Pto encodes a serine-threonine protein kinase that specifically recognizes strains of Pseudomonas syringae pv. tomato (Pst) that express the avirulence gene avrPto. We examined an accession of the distan...

Serological correlates of immune protection conferred by Chikungunya virus infection.

Chikungunya virus (CHIKV), an Alphavirus of the family Togaviridae is a positive strand RNA virus that is transmitted commonly by the Aedes mosquitoes. The characteristic clinical symptom of the virus infection is incapacitating arthralgia that could persist for few weeks to several months in the affected individuals (1, 2). High morbidity with severe polyarthralgia, rashes and ocular, hemorrha...
