I-3: Reactive Oxygen Species: A Dilemma for

Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...

Biodistribution and Clearance of I-labeled C-reactive Protein and I-labeled Modified C-reactive Protein in Cd-1 Mice

Iodinated forms of C-reactive protein (CRP), soluble modified CRP (mCRP-sol), and suspended mCRP (mCRP-susp) were injected iv into CD-1 mice, for analysis of their pharmacokinetics (PK) and biodistribution (BD). The plasma half-life of I-CRP, measured as 4.7 hr, agrees closely with previous reports. The PK and BD characteristics for I-mCRP-sol and I-mCRP-susp were comparable to each other and w...

How do I approach patients with warm-reactive autoantibodies?

W arm-reactive autoantibodies are the most common cause of autoimmune hemolytic anemia, with the incidence of these antibodies increasing with patient age. They have been reported in children as young as a few months of age, and there are two case reports of neonates who seem to have developed warm-reactive autoantibodies in utero. They are a relatively common finding at Arkansas Children’s Hos...

The continuous prisoner's dilemma: I. linear reactive strategies.

We present a general model for the Prisoner's Dilemma in which variable degrees of cooperation are possible, and payoffs are scaled accordingly. We describe a continuous strategy space, and divide this space into strategy families. We derive the payoff function for these families analytically, and study the evolutionary outcome when a wide range of strategies play against each other. Our result...
