Antibiotics improve health and productive performance of pigs. There is increasing evidence that other dietary ingredients may provide similar, but probably not identical, benefits. A properly prepared immune egg product, spray-dried plasma, or a high level of dietary zinc can provide protection against enteric infection in young pigs. Spray-dried plasma also increases growth rate dramatically,...

The technique of near forward laser scattering is used to infer characteristics of intrinsic and controlled density fluctuations in laser-produced plasmas. Intrinsic fluctuations are studied in long-scalelength plasmas where we find that the fluctuations exhibit scalesizes related to the intensity variation scales in the plasma-forming and interaction beams. Stimulated Brillouin forward scatter...

Actin is involved in endocytosis in organisms ranging from yeast to mammals. In activated Xenopus eggs, exocytosing cortical granules (CGs) are surrounded by actin "coats," which compress the exocytosing compartments, resulting in compensatory endocytosis. Here, we examined the roles of two myosins in actin coat compression. Myosin-2 is recruited to exocytosing CGs late in coat compression. Inh...

Plasma-Assisted Combustion (PAC) has shown potential in improving the ignition, extinction, and dynamic performance of combustion systems. In this work, nanosecond repetitively pulsed (NRP) spark discharges are applied to extend lean blow out (LBO) limit SICCA-Spray burner. This laboratory-scale atmospheric test rig is equipped with a swirl spray injector representing an idealized fashion singl...

Two trials were conducted to determine the effects of irradiation of individual ingredients or the whole diet on growth performance in nursery pigs. The response was similar for both trials with pigs fed diets containing irradiated spray-dried animal plasma or soybean meal having increased (P<0.05) ADG compared with pigs fed the control diet with no irradiated ingredients or the complete diet t...

The pollen coat protects pollen grains from harmful environmental stresses such as drought and cold. Many compounds in the pollen coat are synthesized in the tapetum. However, the pathway by which they are transferred to the pollen surface remains obscure. We found that two Arabidopsis thaliana ATP binding cassette transporters, ABCG9 and ABCG31, were highly expressed in the tapetum and are inv...

Variations on the statement "the variant surface glycoprotein (VSG) coat that covers the external face of the mammalian bloodstream form of Trypanosoma brucei acts a physical barrier" appear regularly in research articles and reviews. The concept of the impenetrable VSG coat is an attractive one, as it provides a clear model for understanding how a trypanosome population persists; each successi...

BACKGROUND Prolonged storage of platelets could improve availability and logistical management and decrease wastage. Immunobiochemical methods can be used to guarantee the quality of platelets after prolonged storage. OBJECTIVE The aim of this study was to compare storage-related changes in buffy coat-derived platelet concentrations versus platelet-rich plasmal. METHODS Units of whole blood...
