Novosphingobium pentaromativorans US6-1 is a halophilic marine bacterium able to degrade polycyclic aromatic hydrocarbons (PAHs). Genome sequence analysis revealed that the large plasmid pLA1 present in N. pentaromativorans US6-1 consists of 199 ORFs and possess putative biodegradation genes that may be involved in PAH degradation. 1-DE/LC-MS/MS analysis of(More)
Endosulfan (1,4,5,6,7,7-hexachloro-8,9,10-trinorborn-5-en-2,3-ylenebismet-hylene) is correlated with endocrine disruption, reproductive, and immune dysfunctions. Recently, endosulfan was shown to have an effect on inflammatory pathways, but its influence on cyclooxygenase-2(COX-2) expression is unclear. This study investigated the effects of COX-2 and(More)
A high power wideband feedback amplifier module using AlGaN/GaN high electron mobility transistor (HEMT) has been developed that covers the frequency range of DC to 5GHz with small signal gain of 9 dB. Shunt feedback topology is introduced by adding inductances to increase the bandwidth. At midband frequency, power added efficiency (PAE) of 20 % and(More)
Three experiments were conducted to investigate the feasibility of using crystalline methionine and lysine as protein supplements for lactating Holstein cows. In the first experiment, Met (dl-methionine) and Lys (l-lysine-HCl) were added to diets used in continuous culture bioreactors to estimate optimal concentrations for use in subsequent in vivo(More)
As the use of nursing diagnoses in clinical practice increases, systematic research is necessary to appropriately validate them. Validity studies could be expedited by the use of information technology and computerized clinical data bases. The purpose of the following descriptive study was to validate the defining characteristics (risk factors for potential(More)
Four nonlactating, mature, Holstein cows were fitted with ruminal cannula and used in a 4 x 4 Latin square-designed experiment to evaluate the impact of supplemental Zn and monensin on ruminal degradation of Lys and liquid 2-hydroxy-4-methylthiobutanoic acid (HMB). Cows were fed 4.54 kg (as fed) of alfalfa hay top-dressed with 4.54 kg (as fed) concentrate(More)
Kallikrein has been reported to stimulate callus formation and cell proliferation. It is well-known that vitamin D3 play an role on the metabolism of calcium. However, the relation between vitamin D3 and kallikrein are still poorly understood. We have studied the effect of kallikrein on calcium and vitamin D3 with canine kidney. Mongrel dogs were(More)
Fig S1. Comparison of survival impact of CuO NPs on the primary rat hepatocyte, the normal liver cell line (Clone 9), and malignant hepatoma cell line (N1S1). After 24h treatment of CuO NPs, normal and Clone 9 cells show a greater tolerance toward CuO-induced toxicity than malignant N1S1 cells. Animal care and experimental procedures were approved by the We(More)
