SummaryA case of histidinemia is described in which the biochemical abnormality can be attributed to a deficiency of the enzyme histidase. As a result of this deficiency, plasma and urinary levels of histidine are markedly elevated. Imidazolepyruvic, imidazolelactic, and imidazoleacetic acids ar...
Histidinemia is an inherited metabolic disorder caused by deficiency of histidase activity, which leads to tissue accumulation of histidine and its derivatives. Affected patients usually present with speech delay and mental retardation, although asymptomatic patients have been reported. Consider...
In recent years, nitric oxide (NO) has been considered a plant signaling compound involved in antioxidant systems and flavonoid production enhancement. Nevertheless, its mechanism of action, from the perspective of protein expression, remains largely unknown. In this study, isobaric tags for rel...
Exposure to cyanide is widespread in human populations due to a variety of natural and anthropogenic sources. The potential health risks of excess cyanide exposure are dose-dependent and include effects on the thyroid, the male reproductive system, developmental effects, neuropathies and death. ...
A new three-dimensional diamagnetic metal nitronyl nitroxide radical coordination polymer with an aqua cadmium cyanide framework Cd(NIT4py)(H2O)Cd(CN)4·H2O 1, was synthesized. X-ray crystallography reveals that the structure consists of 3D aqua cadmium cyanide built up by octahedral CdII coordi...
Oxalate-adsorbed TiO2 shows visible activity for the oxidation of ranitidine, although neither oxalate nor pure TiO2 alone absorbs visible light. The formation of an oxalate-TiO2 complex facilitates electron transfer from oxalate to the TiO2 conduction band (CB) (i.e., a ligand-to-metal charge t...
Industrial wastewaters containing biorefractory compounds like cyanide offer significant environmental problems attributed to the fact that the conventional methods have limited effectiveness and hence developing efficient treatment approaches is an important requirement. The present work invest...
Uptake, assimilation, and toxicity of exogenous iron cyanide complexes in plants were investigated. Pre-rooted young weeping willows (Salix babylonica L.) were exposed to hydroponic solutions spiked with potassium ferrocyanide at 24.0±1 °C for 192 h. Transpiration rates, chlorophyll contents, ...
An inexpensive and disposable screen printed sensor capable of monitoring pH is described. Based on a custom designed flavin derivative (10-(4-hydroxyphenyl) benzo[g]pteridine-2,4(3H,10H)-dione), electro-oxidation of the phenolic substituent leads to the deposition of a redox film whose peak pos...
Water molecules present as an interstitial impurity in crystals of Pb2Fe(CN)6 · 2H2O in excess of bonded water is found to activate electronic conduction with an activation energy of 0.32 eV. A quantitative explanation is given to show why lead and several other heavy metal ferrocyanides have a...
The use of crystallization inhibitors has been proposed as a potential preventive treatment method against damage and is extensively tested for crystallization of single salts. However, in practice salt mixtures are present. Therefore, before using inhibitors in practice there is a strong need t...
A novel polyvinylidene fluoride (PVDF) membrane was fabricated through chemical binding SiO2 nanoparticles (NPs) and copper ferrocyanide (CuFC) layers onto a membrane surface simultaneously to improve the removal efficiency of Cs. The results indicated that the SiO2 NPs were strongly deposited o...
The preparation of trihydroxy lead ferrocyanide and monohydroxy lead ferrocyanide is described. The solubility product of the latter is 3·18 × 10−25 at 35°C. Infrared spectra and thermogravimetric studies are reported.
The selectivity and fast exchange kinetics of porous silica adsorbents containing Cu or K ferrocyanide make them ideal candidates for the column decontamination of 137Cs effluents. The exchange thermodynamics of the K+ ions in Sorbmatech® (S202, one such adsorbent) with the major cations present...
SummaryAqueous organic/organometallic redox flow batteries (AORFBs) have gained increasing attention for large-scale storage of intermittent renewable energy (e.g., solar and wind) due to the advantages of decoupled energy and power, high current and power performance, safety features, and synth...
The detoxification of iron cyanide in a soil–plant system was investigated to assess the total cyanide extracted from contaminated soil and allocated in the leaf tissue of willow trees (Salix caprea). They were grown in soil containing up to 1000 mg/kg dry weight (dw) of cyanide (CN), added as ...
Partial demercaptalation of 2-deoxy-2-(trifluoroacetamido)-D-glucose diethyl dithioacetal yielded ethyl 2-deoxy-1-thio-2-(trifluoroacetamido)-α-D-glucofuranoside (2). This compound was also prepared by deacetylation of ethyl 2-acetamido-3,5,6-tri-O-acetyl-2-deoxy-1-thio-α-D-glucofuranoside fol...
In this study, effect of some ionic liquids on the thermodynamic and transport properties of L(+)–lactic acid in aqueous polyethylene glycol solutions have been investigated. Density, speed of sound, and viscosity of L(+)–lactic acid in the aqueous solutions of polyethylene glycol, polyethylen...
In this paper, the effect of some ionic liquids on the conductivity behavior of l(+)–lactic acid was studied in polyethylene glycol aqueous solutions. The molar conductivities of l(+)–lactic acid in the aqueous solutions of polyethylene glycol, polyethylene glycol + 1–butyl–3–methylimidazol...
The effects of hydrogen bonding, inter- and intramolecular electrostatic interactions on the structure of 4-carboxy-1-methylpyridinium chloride (1-Me-isonicotinic acid chloride, 1-methyl-isonicotinium chloride), MINH·Cl, in the crystal and isolated molecule have been studied by X-ray diffractio...
