We have studied the effect of local anesthetics QX 572, which is permanently charged, and benzocaine, which is neutral, on batrachotoxin-activated sodium channels in mouse neuroblastoma N18 cells. The dose-response curves for each drug suggest that QX 752 and benzocaine each act on a single class of binding sites. The dissociation constants are 3.15 X 10(-5) M for QX 572 and 2.65 X 10(-4) M for...

Two field trials were conducted to determine the effect of P-K solubilizing bacteria and nitrogen chemical fertilizer on growth, yield nitrate in leaf mustard greens Brassica juncea L.) cultivated acid sulfate soils. Eight bacterial strains composed 3 Acinetobacter calcoaceticus 5 Rhizobium sp., liquid directly watered into plant at stages [6, 12 21 days after planting] during vegetable cultiva...

Fly stocks Fly culture and crosses were grown on standard fly medium at 25 8C. Oregon R were used as wild-type standard. The BG00650 line was obtained from the Bloomington stock centre. Dredd , Relish, Dif 1 and imd were described elsewhere. The P-element inserted in BG00650 was mobilized by following standard crosses. Mobilization events were screened by PCR using different primer combinations...

We consider the discretization of an optimal boundary control problem with distributed observation by the boundary concentrated finite element method. With an H(Ω) regular elliptic PDE on two-dimensional domains as constraint, we prove that the discretization error ‖u∗ − uh‖L2(Γ) decreases like N −δ, where N denotes the total number of unknowns. For the case δ = 1 in convex polygonal domains, t...

We study the complexity of natural equivalence relations on classes of computable structures such as isomorphism and bi-embeddability. We use the notion of tc-reducibility to show completeness of the isomorphism relation on many familiar classes in the context of all Σ1 equivalence relations on hyperarithmetical subsets of ω. We also show that the bi-embeddability relation on an appropriate hyp...

In Sweden, drainage and the construction of water infrastructure have influenced agriculture in last few centuries both positively negatively. Recently, a trend has set where wetlands are constructed to retain water, reduce nutrients enhance biodiversity. This study aimed use remote sensing techniques landscape retention over time. this pilot study, structures Gotland (57°28′35.0′′N18°29′ 13.9′...

Several markers have been studied for their ability to make the CNS infiltration diagnosis earlier and more precise; previous studies showed that CSF ferritin concentrations were higher in patients with malignant invasion of CNS. The objective was to determine the importance of CSF ferritin as a biomarker for the diagnosis of CNS neoplastic infiltration. This study is based on 93 CSF samples, d...

Cystic echinococcosis (CE) is a high prevalent zoonosis in the central and southern Peruvian Andes. Serum samples (n50)from patients presenting presumptive clinical and radiological diagnosis of CE (group 1), were tested for antibodies against Echinococcus granulosus metacestode using Arc-5 double diffusion assay (DD5), immunoelectrophoresis (IEF), and immunoelectrotransfer blot (EITB) techniqu...
