BackgroundSelenium supplementation can be used to treat tumors. However, inorganic selenium is highly toxic, and natural organic selenium is extremely rare. Polysaccharides can improve drug bioavailability and targeting. Lentinan is a polysaccharide that has been approved as an anti-cancer drug ...

The inhibitory effects of sulfated lentinan with different degrees of sulfation against tobacco mosaic virus (TMV) and the underlying mechanism were investigated. The results indicated that plants treated with increasing concentrations of sulfated lentinan, with increasing numbers of treatments ...

The synthesis of transition metals Wells Dawson heteropoly salts along with their elemental composition, water content, structure and specific surface area were thoroughly investigated. Additionally, the use of a molecular probe such as pyridine allowed the quantification of Lewis and Brønsted s...

In the present study, we synthesized and evaluated the anti-inflammatory effects of the two component hybrids, caffeic acid (CA)-ferulic acid (FA), FA-Tryptamine (Trm), CA-Piperonyl Triazol (PT) and FA-PT. Of these five hybrids, CA-FA had the most potent inhibitory effect on butyrylcholinesteras...

BackgroundNatriuretic peptides play an important role in the diagnosis and risk stratification of patients with acute and chronic heart failure. Multiple studies have shown that these peptides are liable to the influence of individual factors. For N-terminal-pro-B-type natriuretic peptide (NT-pr...

BackgroundWith sacubitril/valsartan treatment, B-type natriuretic peptide (BNP) concentrations increase; it remains unclear whether change in BNP concentrations is similar across all assays for its measurement. Effects of sacubitril/valsartan on atrial natriuretic peptide (ANP) concentrations in...

ObjectivesThe aim of this study was to determine if the atrial natriuretic peptide (ANP) precursor proANP is biologically active compared with ANP and B-type natriuretic peptide (BNP).

ObjectiveTo investigate whether the combination of measuring amino-terminal pro-B-type natriuretic peptide (NT-proBNP) and B-type natriuretic peptide (BNP) could provide additional prognostic value in hospitalized heart failure patients.

Background and objectiveTo compare plasma N-terminal pro-atrial natriuretic peptide concentrations in preeclamptic patients and healthy normotensive pregnant women.

Glycosylation of 1,2-Dihydro-5-(1H-indol-2-yl)-1,2,4-triazole-3-thione with 2,3,4,6-tetra-O-acetyl-α-d-glucopyranosyl bromide, 2,3,4,6-tetra-O-acetyl-α-d-galactopyranosyl bromide and 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-α-d-glucopyranosyl chloride was investigated in the presence of Et3N an...

The synthesis of 5′-O-β-d-glucopyranosyl and 5′-O-β-d-galactopyranosyl derivatives (13 and 15, respectively) of the antiviral agent ribavirin are descrobed. Direct glycosylation of 2′,3′-O-isopropylideneribavirin with either tetra-O-acetyl-α-d-glucopyranosyl bromide (4) or tetra-O-acetyl-...

The effects of chronic exposure to three sulphur-containing heterocyclic N-nitrosamines were determined after repeated oral administration to female Fischer 344 rats. Nitrosothiazolidine did not significantly affect the survival of the rats or the incidence of tumours at a total dose of 3.5 mmol...

A series of heterometal substituted gallium phosphates, (N2C4H7)0.5+x[Me0.5+xGa2.5−x(PO4)3] (Me = Mn, Fe, Co and Zn, x ≈ 0.25), has been synthesised under solvothermal conditions at 433 K in ethylene glycol using 1-methylimidazole as a templating agent and their structures determined at 150 K u...

In this study, palladium (II), platinum (IV), rhodium (III) and iridium (IV) were sequentially separated with 1-hexyl-3-methylimidazole-2-thione (HMImT) from aqueous hydrochloric acid media by adjustment of hydrochloric acid concentration or in the presence of tin (II) chloride using environment...

Three new coordination polymers [M(Pht)(1-MeIm)2]n (where M=Cu (1), Zn (2), Co (3); Pht2−=dianion of o-phthalic acid; 1-MeIm=1-methylimidazole) and two compounds [M(1-MeIm)6](HPht)2 · 2H2O (M=Co (4), Ni (5)) have been synthesized and characterized by X-ray crystallography. The structures of 1–...
