The stimulatory or inhibitory effects of plant lectins on the production of gelatinase A (MMP-2) and gelatinase B (MMP-9) by mononuclear white blood cells was investigated by substrate zymography. Leukocyte cultures from 24-h old buffy coats were spontaneously activated and produced high levels of gelatinase B. Using such cultures the suppressing activity of the Datura stramonium, Viscum album,...

To support the use of marine demosponges for collagen production in integrated culture settings, we investigated a low–cost, easily applicable and sustainable method Chondrosia reniformis Nardo, 1847 ( Demospongiae , Chondrosiida Chondrosiidae ). Novel methods were tested to this collagen-rich demosponge three consecutive trials, during which recovery, survival growth rates explants monitored c...

Soybean breeding lines and reported sources of nematode resistance were evaluated in repeated greenhouse tests for resistance to North Carolina populations of the soybean cyst nematode Heterodera glycines, reniform nematode Rotylenchulus reniformis, and the root-knot nematode species Meloidogyne incognita, M. arenaria, and M. arenaria. Lines from the soybean breeding program in Missouri that ha...
