Sn-SBA-15 was prepared by different methods seeking to tailor its catalytic properties. The effect of the SBA-15 synthesis pH and Sn loading in the Sn-SBA-15 structure, porosity, and type of generated Sn species on catalyst activity towards glucose isomerization was systematically evaluated. Inc...

BackgroundGrowth differentiation factor 15 (GDF-15) is a marker of cell senescence. Age is a well-known determinant of GDF-15 levels, yet no study has analyzed the relationship between geriatric conditions and GDF-15. We hypothesize that geriatric conditions reflecting biological age might be st...

Human 15-lipoxygenase-1 (15-LOX-1) is a mammalian lipoxygenase which plays an important regulatory role in several CNS and inflammatory lung diseases. To further explore the role of this enzyme in drug discovery, novel potent inhibitors with favorable physicochemical properties are required. In ...

BackgroundThe aim of this study was to assess the levels, kinetics, and prognostic value of growth differentiation factor 15 (GDF-15) in cardiogenic shock (CS).

Specific detection of amanitins in body fluids is necessary for an early diagnosis of an intoxication with amanita mushrooms. In this paper, a liquid chromatographic-mass spectrometric assay after immunoaffinity extraction (IAE-LC–MS) is described for the determination of α- and β-amanitin in...

Zh. Zhelev, A.Zheleva and K. Halacheva. Preparation of a β-amanitin - concanavalin A conjugate of low toxicity. Toxicon25, 981 – 987, 1987.—Pure β-amanitin was isolated by combined adsorption chromatography of a crude methanol extract from Amanita phalloides on Sephasorb HP Ultrafine and Sep...

A high-performance liquid chromatographic assay of α-amanitin and β-amanitin in human serum, urine, or stomach washings is described. Sample preparation involves a chemical step with deproteinization and organic solvent treatment, and a selective cleanup and concentration step on reversed-phas...

Poisonings with Amanita phalloides toxins require fast diagnosis in order to avoid expensive and unnecessary therapies. Initial clinical assessment in combination with urinary amanitin analysis is necessary for a definite diagnosis. Therefore, a simple, fast, and robust method was developed for ...

Amanitins are toxins found in species of the mushroom genera Amanita, Lepiota and Galerina. Intoxication after ingestion of these mushrooms can be fatal with an estimated 20% of mortality rate. An early diagnosis is necessary in order to avoid invasive and expensive therapy and to improve patien...

This paper presents a method for the simultaneous determination of α-amanitin, β-amanitin and muscarine in human urine by solid-phase extraction (SPE) and ultra-high-performance liquid chromatography coupled with ultra-high-resolution TOF mass spectrometry. The method can be used for a diagnos...

α-Amanitin and β–amanitin are the main toxins of mushroom poisoning. The application of traditional non-selective adsorbents is not satisfactory in clinical treatment of amanita mushroom poisoning due to lack of specificity adsorption capability of these adsorbents toward amanitin toxins. In ...

The majority of fatalities from poisonous mushroom ingestion are caused by amatoxins. To prevent liver failure or death, it is critical to accurately and rapidly diagnose amatoxin exposure. We have developed a liquid chromatography tandem mass spectrometry method to detect α-, β-, and γ-amani...

Equilibria of EuO dissolution and dissociation in molten (NaBr + NaI) mixtures of 0.77:0.23 and 0.31:0.69 compositions at T = 973 K were studied by potentiometric titration method using Pt(O2)|ZrO2(Y2O3) indicator electrode. The solubility product indices of EuO are (7.81 ± 0.08) and (8.43 ± 0...

The nanostructured particles of europium(III) complexes with tri-n-octyl phosphineoxide (TOPO) and naphthoyl trifluoroacetone (NTA) ligands containing gold nanoparticles (GNPs) were successfully prepared by using the modified Stöber method. Their morphologies and optical properties were investig...

Polarization behaviour of Eu, Sm, and Gd was investigated in acidic sulfate solutions using Cu and Cu–Hg cathodes and electrolytic reduction–precipitation of europium from sulfate solutions was studied using a mercury-coated copper electrode. The effect of magnetic stirring, N2 gas sparging, a...

A simple method is presented for the preparation of novel europium complexes-grafted-oxidative dopamine (ECOD) nanoparticles with uniform sizes (ca. 220 nm), as a high-performance nanotheranostic agent guided by X-ray computed tomography (CT) and photoluminescence (PL). Here, an oxidative dopami...

Batch experiments and detailed solid-phase characterization (i.e., powder X-ray diffraction, scanning electron microscopy, and infrared spectroscopy) were used to determine the effect of secondary phase formation on the adsorption of europium and neptunium to a suite of aluminum (hydr)oxide mine...
