Nyvatex Health-Mat(TM) Shown to Stimulate T-Cell Proliferation BILLINGS, Mont., Sept. 21 /PRNewswire-FirstCall/ -- Nyvatex (OTC:NYVA) announced today that an in vitro test of its patented Nyvalon(TM) Health-Mat(TM) at a prominent Midwestern university showed a statistically significant 55% improvement in T-cell proliferation in blood samples placed with Nyvalon(TM) versus the control. Blood from 12 volunteers over 65 years of age was tested by incubation in cultured media with and without PHA (which activates T-cells). Nyvalon(TM)'s effect on T-cells treated with PHA was not statistically significant, but T-cells in culture media alone without PHA treatment proliferated to a statistically significant value of 0.547 when exposed to Nyvalon(TM), compared to 0.353 when not exposed to Nyvalon(TM). Nyvatex CEO John C. Ledbetter stated that the improvement in non-PHA-treated T-cells suggests that Nyvalon(TM) is encouraging proliferation of naive T-cells. Describing the potential significance of the test results, Ledbetter stated: "These results may offer an explanation for the substantial immune system benefits reported over many years by users of the Nyvatex Health-Mat(TM). We have seen that people who sleep on the Health-Mat(TM) do not suffer the annual cough-cold-flu syndrome experienced by most of the U.S. population."
