We studied imidacloprid application methods and timing to control the hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), in forests. The methods compared were 1) soil injection near the trunk; 2) soil injection dispersed throughout the area under the canopy; 3) soil drench near the base of the trunk; and trunk injection with the 4) Arborjet, 5) Wedgle, and 6) Mauget systems. ...

The uptake of zinc, an essential nutrient, is critical for cell proliferation. On the basis of the idea that zinc uptake can be an index of viability in proliferating cells, tumor imaging with (65)Zn was performed using autoradiography. After s.c. implantation of ascites hepatoma (AH7974F) cells into the dorsum, 1 h after i.v. injection of (65)ZnCl(2), (65)Zn uptake in the tumor was higher than...

In our previous work fused pyrimidine and thiopyrimidine nucleoside analogs (2, 3b, 3c, 4a and 4c) as well as sulfated oligosaccharides (Maltose SO4, Raffinose SO4, Stachyose SO4, Chondroitin-6-sulfate, Maltohexaose SO4) were prepared. The objective of this study was to elucidate the antitumor activity of prepared compounds against Erlich ascites carcinoma cells (EAC) bearing mice through monit...

Four thorium sulfate compounds have been synthesized and characterized. [Th(SO4)2(H2O)7] 2H2O (ThS1) crystallizes in space group P21/m, a1⁄47.2488(4), b1⁄412.1798(7), c1⁄48.0625(5) Å, b1⁄498.245(1); Na10[Th2(SO4)9(H2O)2] 3H2O (ThS2), Pna21, a1⁄417.842(2), b1⁄46.9317(8), c1⁄427.550(3) Å; Na2[Th2(SO4)5 (H2O)3] H2O (ThS3), C2/c, a1⁄416.639(2), b1⁄49.081(1), c1⁄425.078(3) Å, b1⁄4 95.322(2); [Th4(SO...

Effects of adrenalectomy on increases in noradrenaline (NA) turnover induced by a one-hour immobilization stress were examined by measuring the levels of NA and its major metabolite, 3-methoxy-4-hydroxyphenylethyleneglycol sulfate (MHPG-SO4) in specific brain regions of the rat. Bilateral adrenalectomy alone does not affect basal levels of NA and MHPG-SO4 in the brain regions examined with the ...

Abstract Key message Trunk injection causes injury to trees and best practices must be established for use of this technology manage vascular diseases such as huanglongbing. is a technique applying plant protection compounds that has demonstrated efficacy management huanglongbing (HLB), bacterial disease which devastated the Florida citrus industry. Recently, antibacterial oxytetracycline been ...

We investigated the effects of a wheat-based diet (WBD) supplemented with different levels of zinc on the performance, intestinal viscosity, immune system and lipid peroxidation of broiler chickens. A total of 240 Ross 308 day-old male broiler chicks were weighed and assigned to six dietary treatments with four replicates (floor pens) of ten birds per pen. Dietary treatments consisted of a WBD ...

We present new data of oxygen isotopes in marine sulfate ( δ 18 O SO4 ) in pore fluid profiles through organic-rich deep-sea sediments from 11 ODP sites around the world. In almost all sites studied sulfate is depleted with depth, through both organic matter oxidation and anaerobic methane oxidation. The δ 18 O SO4 increases rapidly near the top of the sediments, from seawater values of 9‰ to m...

representation of the dimeric units of K2[Zr(SO4)3]. 2H20. Examination of this structure shows that breaking and remaking one oxygen bridge in each dimeric ring of K2[Zr(SO4)3.2H20 would result in the formation of infinite-Zr-O-SO -Zr-chains similar to those found in Na2[Zr(SO4)3]. 3H20 [Fig. 3(c)] and we see that in these two compounds we have an extension of the structural arrangements alread...
