Polymorphonuclear leukocyte chemotaxis has been elicited by oxidized arachidonic acid and other polyenoic lipids in the Boyden micropore filter assay system. This chemotactic activity was observed absence of serum proteins. The esterfied present plasma membranes may be a precursor messages as well prostaglandins vivo.

A distinction is drawn between the virgin fescue prairie described as Festuca scabrella association, and grassland produced by mowing for hay or grazing. The climax dominated scabrella, characterized some 150 species of higher plants. Various associated species, notably a few grasses, increase greatly in frequency coverage when used meadow pasture, while shows corresponding decline. Where grazing has been heavy virtually disappeared. association considered relation to Stipa, poplar, other...

Improvement of the sucrose content commercial sugarcane by conventional breeding has reached a plateau, primarily due to narrow gene pool, and potential introduce novel genes or manipulate native influence metabolism may have significant application. This review reports on progress in developing new, optimising existing, transformation processes for sugarcane, confirms that requisite molecular tools modifying are as yet poorly developed when compared with those currently being applied...

The use of the green fluorescent protein (GFP) and in vivo screening for transgenic cells has enabled first visual selection sugarcane (Saccharum L. hybrid) transformed by Agrobacterium-mediated techniques. Selection GFP-positive embryogenic callus using Agrobacterium tumefaciensstrain AGL0 was performed fluorescence microscopy 6 weeks after transformation.

Abstract The use of polymers in plastic and rubber products has generated concern that monomers potentially active biological systems may be eluted from these substances. We have evaluated two such monomers, acrylonitrile styrene, for the induction chromosome damage mice. Butadiene monoxide, a presumed metabolite third important monomer, 1,3‐butadiene, was also tested. These chemicals were administered as single intraperitoneal injection; sister chromatid exchanges aberrations analyzed bone...

Abstract The industrial chemical acrylamide is suspected to induce potentially heritable genetic damage. While several studies in rodents have indicated that this substance can damage spermiogenic cells, resulting dominant lethals and translocations, cytogenetic assessments of premeiotic meiotic cells after exposure produced equivocal results. In the present study, various endpoints both somatic germ‐line from acrylamide‐treated mice were evaluated. Sister chromatid exchanges micronuclei,...
