A comparison of the tris(trimethylsilyl)silyl I and tris(trimethylsilyl)germyl II radical reactivity is provided. Their formation as well as their reactivity encountered in a large variety of chemical processes (addition to double bond, halogen abstraction, peroxyl radical formation…) is examin...

The title compound methyl(2E)-2-{[N-(2-formylphenyl)(4-methylbenzene)sulfonamido] methyl}-3-(2-methoxyphenyl)prop-2-enoate (MFMSM) has been synthesized and single crystals were grown by slow evaporation solution growth technique at room temperature. XRD, FT-IR and NMR spectra of MFMSM in the sol...

A series of 2,3-diaryl-4-thiazolidinone derivatives were synthesized and evaluated for their antiproliferative properties against two well-known cancer cell lines (A549 as human lung cancer and MDA-MB-231 as human breast cancer). Structure activity relationship (SAR) analysis resulted in the dis...

Tailorable deposition was carried out by varying the Sn:Ni molar ratio of a pyrophosphate bath to adjust the deposition rate as well as the phase composition, morphology and corrosion resistance of the as-deposited SnNi alloy. The nickel content of the resultant SnNi alloy decreases gradually fr...

This paper presents the synthesis and thermal behavior of double copper and potassium pyrophosphate, which can be used as a PK fertilizer containing copper as micronutrient. In order to find the conditions for the synthesis of this compound from copper sulphate and potassium pyrophosphate, vario...

Ternary copper-zinc-tin coatings have been prepared by a one-step electrodeposition on molybdenum sputtered soda-lime glass (SLG) (20ÿ20 mm2) from an aqueous pyrophosphate electrolyte at room temperature. The plating bath contains copper(II), zinc(II), tin(II) and potassium pyrophosphate at pH =...

Over the last decade, nanoporous metals have attracted a growing attention due to the combination of structural and functional properties, such as their very high surface to volume ratio and mechanical rigidity. A recent and versatile process producing nanoporous metals is the dealloying of an i...

Magnesium is being increasingly used in various industries, including aerospace, automotive, construction, computers, medical, consumer electronics and the military. World production of magnesium currently totals about 400,000 tons per year. The low density of magnesium (33% lighter than aluminu...

A new environmentally friendly non-chromated chemfilm with different pretreatments was studied as a replacement to conventional hexavalent chromium-based chemfilm technologies for magnesium alloys. Anti-corrosion and paint adhesion properties of conversion-coated sand-cast AZ92A-T6 magnesium all...

Mesobilirubin or dihydromesobilirubin were converted by a pure strain of rat Clostridia to class II and III urobilinoid chromogens (l-half-stercobilinogen and l-stercobilinogen). This was also true in some experiments with various samples of human fecal flora; in others, only or mainly class I (...

Mesobiliverdin IXα diesters of α,ω-dialkanols were obtained by reaction of mesobiliverdin IXα dicesium salt with diiodomethane, 1,3-dibromopropane and 1,4-dibromobutane. Mesobiliverdin IXα methylene diester was tested and compared to mesobiliverdin IXα dimethyl ester, for their photoisomer...

Symmetric analogs of mesobilirubin-XIIIα, with propionic acid groups shortened and lengthened, exhibit induced circular dichroism (ICD) in CH2Cl2 solvent with excess S-(−)-methyl-p-tolylsulfoxide. The dimethyl esters of mesobilirubins with acetic, propionic, butyric, valeric and caproic acid ch...

The Fourier-transform Raman (FT-Raman), infrared (FT-IR), and UV-visible absorption spectra of four dipyrrinones and two mesobilirubins have been investigated in the solid state and in CH2Cl2 solutions. A detailed spectral analysis, assignment and discussion of these spectra are presented. The b...

SummaryThe poison gyromitrin, found in the edible false morel Gyromitra esculenta Fr. ex Pers., caused in rats an increased diuresis in which urine was produced with a weak alkaline pH, a high excretion of sodium (530%), and potassium (210%). The observed increase lasted for about 12 h and was f...

After oral application of the mushroom poison gyromitrin a time and dose dependent decrease of cytochrome P-450 was found in rat liver microsomes. The maximal decrease to about 50–60% of the control (after 200 mg/kg, 80% of LD50) was observed 8–12 h after application, a normalization after 48 ...

Consumption of false morel (Gyromitra esculenta Fr.) has been associated not only with acute poisoning, but also with a carcinogenic risk. The hydrolysis of acetaldehyde-N-methyl-N-formylhydrazone (gyromitrin, the main toxic component of false morel) results in the formation of the methylating a...

The main toxic compound found in false morel (Gyromitra esculenta) is acetaldehyde-N-methyl-N-formylhydrazone (gyromitrin). This paper describes a method of determining the total hydrazones content based on acid hydrolysis of gyromitrin and other related hydrazones in air-dried false morel follo...

Different mass R-290 (propane) leaked into the room from the inside and outside of a split type air conditioner indoor unit, and the refrigerant concentration was measured by infrared gas sensors. A CFD mode for RAC indoor unit including heat exchanger and fan was developed and verified by the t...

In this study, the biosorption of Acid Blue 290 and Acid Blue 324 on Spirogyra rhizopus, a green algae growing on fresh water, was studied with respect to initial pH, temperature, initial dye concentration and biosorbent concentration. The optimum initial pH and temperature values for AB 290 and...

Proteoglycans (PGs) are important macromolecules in mammalian cells, consisting of a core protein substituted with carbohydrate chains, known as glycosaminoglycans (GAGs). Simple xylosides carrying hydrophobic aglycons can enter cells and act as primers for GAG chain synthesis, independent of th...
