Penaeus japonicus (12.83 +/- 1.24 g) which were exposed individually to 0.002 (control), 0.076, 0.362, 0.719 and 1.433 mM nitrite at 30 ppt of salinity were examined for hemolymph ammonia, urea and nitrite, and nitrogenous excretion after 3, 6, 12, 24 and 48 h, respectively. Hemolymph nitrite and hemolymph urea increased directly with ambient nitrite and(More)
Penaeus monodon (10.56 +/- 0.71 g) exposed individually to 0.026 (control), 0.774, 3.646, 7.004, 21.234 and 36.079 mM nitrate in 25 ppt seawater were examined for nitrate accumulation in hemolymph, gill, eyestalk, heart, foregut, midgut, hepatopancreas and muscle after 1, 3, 6, 12 and 24 h, respectively. Concentration of nitrate in the tissues increased(More)
The administration of 2-methoxyethanol (2-ME) to pregnant rats, mice, or primates results in developmental toxicity. To assess the role of metabolism in the adverse response of 2-ME, carbon-13 NMR spectroscopy was used to examine, directly in the urine, metabolites produced after administering high (250 mg/kg) and low (25 mg/kg) doses of(More)
TNFα is one of the initial and important mediators to activate downstream signaling pathways by binding to trimerized TNFα receptors (TNFR), and thus is an ideal drug target for cancer therapy. Taking advantage of intrinsic homotimerization of the globular domain of adiponectin (gAD), we have developed a novel TNFα antagonist, the trimerized fusion protein(More)
Penaeus monodon (12.13+/-1.14 g) exposed individually to six different nitrite and nitrate regimes (0.002, 0.36 and 1.46 mM nitrite combined with 0.005 and 7.32 mM nitrate), at a salinity of 25 ppt, were examined for hemolymph nitrogenous compounds and whole shrimp's nitrogen excretions after 24 h. Nitrogen excretion increased directly with ambient nitrite(More)
The intelligent control technology with the traditional control theory formats intelligent compound controller in order to learn from each other and improve the overall advantage of complementary features. Fuzzy PID control neuron PID control, fuzzy sliding mode control, and optimal control of the neural network. This paper discusses the current situation(More)
OBJECTIVE To evaluate the value of T-cell interferon releases detection of tuberculosis infection(T-SPOT.TB)assay in quick diagnosis of spinal tuberculosis. METHODS From January 2012 to June 2015, a group of 122 diagnosed patients with spinal tuberculosis in the Qingdao Municipal Chest Hospital and a group of 86 patients suspected with spinal tuberculosis(More)
