Ozone (O(3)) is a significant component of atmospheric air pollution and produces detrimental effects in the lung. Although the mechanism of O(3)-induced lung inflammation and injury is unclear, the increased release of the proinflammatory cytokine tumor necrosis factor-alpha (TNF-alpha) by lung cells following O(3) exposure may shed some light on this(More)
The existence of nickel (Ni) deficiency is becoming increasingly apparent in crops, especially for ureide-transporting woody perennials, but its physiological role is poorly understood. We evaluated the concentrations of ureides, amino acids, and organic acids in photosynthetic foliar tissue from Ni-sufficient (Ni-S) versus Ni-deficient (Ni-D) pecan (Carya(More)
The positive regulatory role of PSM/SH2-B downstream of various mitogenic receptor tyrosine kinases or gene disruption experiments in mice support a role of PSM in the regulation of insulin action. Here, four alternative PSM splice variants and individual functional domains were compared for their role in the regulation of specific metabolic insulin(More)
Nickel (Ni) is an essential micronutrient; however, its metabolic or physiological functions in plants and animals are largely uncharacterized. The ribonucleases (RNase, e.g., RNase A) are a large family of hydrolases found in one form or many forms facilitating nitrogen (N) cycling. It is currently unknown how either a deficiency or excess of Ni influences(More)
High-performance liquid chromatography (HPLC) analysis was used for identification of two problematic ureides, asparagine and citrulline. We report here a technique that takes advantage of the predictable delay in retention time of the co-asparagine/citrulline peak to enable both qualitative and quantitative analysis of asparagine and citrulline using the(More)
Entomopathogenic nematodes are used for biological control of insect pests. A method for improved cryopreservation of infective juvenile stage nematodes has been developed using Steinernema carpocapsae and Heterorhabditis bacteriophora. Optimum survival for both species was achieved with 12,000 infective juveniles/ml in glycerol and 7,500/ml in Ringer's(More)
As conserved nuclear factors, Akirins play critical roles in regulating antimicrobial peptides (AMPs) transcription downstream of NF-κB dependent signaling pathways in insects and mammals. However, no any functional studies was reported in penaeid shrimp. The identification and functional analysis of Akirin in the Pacific white shrimp, Litopenaeus vannamei(More)
A new bacterial isolate, 00-50-5, from sunflower head extracts was identified as Bacillus thuringiensis (Bt) according to its morphology. Bt isolate 00-50-5 was highly active against the banded sunflower moth (BSM), Cochylis hospes Walsingham. A sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE) 4-15% gradient gel of whole strain protein of(More)
Field synergy between the molten steel flow field and the temperature distribution was analyzed at first in this paper. It shows when the synergy angle between the molten steel flow field and the temperature gradient field is more than90¡ã in the tundish, the molten steel temperature distribution is more homogeneous and the synergy number is(More)
