The choice of facilitators in medical tourism.

The study identified which of the four facilitators (themselves, agents, insurers, or doctors) consumers are most likely to use when they travel for various medical procedures. A survey conducted between 2011 and 2014 yielded 964 responses. The multinomial logistic regression results showed that being 51-64 years old was positively related to going on their own or using agents to arrange for knee replacements.

Medical tourists: who goes and what motivates them?

This study relates consumers' attitudes toward medical tourism to a number of consumer characteristics, such as age, education, income, and insurance status. Principal components analysis of the attitudes of 289 consumers from various communities of North Carolina resulted in three attitude-related factors: economic, treatment-related, and travel-related. Major findings include: (a) the uninsured and low-income consumers are more sensitive to economic factors than the insured and the middle-income consumers; (b) the 51- to 64-year-olds are less motivated by economic factors than young adults; (c) surprisingly, the better one's health, the more one is motivated by treatment-related factors.

Neuroprotection with delayed calpain inhibition after transient forebrain ischemia.

Objective: Delayed neurodegeneration after transient global brain ischemia offers a therapeutic window for inhibiting molecular injury mechanisms. One such mechanism is calpain-mediated proteolysis, which peaks 24 to 48 hrs after transient forebrain ischemia in rats. This study tests the hypothesis that delayed calpain inhibitor therapy can reduce brain calpain activity and neurodegeneration after transient forebrain ischemia.

Developmental status of neurons selectively vulnerable to rapidly triggered post-ischemic caspase activation.

Caspase activation occurs within 1h of reperfusion in discrete cell populations of the adult rat brain following transient forebrain ischemia. Based on the proximity of these cells to regions of adult neurogenesis and the known susceptibility of developing neurons to apoptosis, we tested the hypothesis that rapidly triggered post-ischemic caspase activation occurs in immature neurons or neuroprogenitor cells. Adult male Long Evans rats were injected with BrdU to label mitotic cells 1, 7, or 28 days prior to being studied.

Comparison of calpain and caspase activities in the adult rat brain after transient forebrain ischemia.

The role of calpain and caspase family proteases in postischemic neuronal death remains controversial. This study compared the timing, location, and relative activity of calpains and caspases in the adult rat brain following 10 min of transient forebrain ischemia. Western blots of cortical, striatal, and hippocampal homogenates demonstrated a alpha-spectrin cleavage pattern indicative of predominant calpain activity, which peaked between 24 and 48 h after reperfusion.
