We propose that the ubiquitous process of Cd homeostasis is likely to outweigh any physiological use of Cd (in place of Zn) in driving oceanic Cd cycling. This is based on the observation that, in our experiments, the Cd-isotopic composition of cultured microbes was independent of the presence/absence of the CdCA1 metalloenzyme (Cd carbonic anhydrase; the only known biochemical function for Cd)...
The influence of metal exposure history on rates of aqueous Cd accumulation, elimination, and subcellular distribution was examined in the aquatic insect Hydropsyche californica. Specimens were obtained from a reference site and a metal-contaminated site and returned to the laboratory where they were continuously exposed to aqueous Cd (518 ng/L, nominal) for 6 d, followed by 9 d of depuration. ...
Amphiphilic γ-cyclodextrin–fullerene 2:1 complexes (C L FC H complexes) were prepared by high-speed vibration milling of lipophilic tail-grafted γ-cyclodextrin (γ-CD), hydrophilic γ-CD and fullerene C 60 . The transamidation γ-CD–fullerene complex having two...
In the title compound, [Cd(C(22)H(26)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·C(3)H(7)NO, the Cd(II) ion is coordinated by four N atoms and two O atoms from two tridentate 1,3-bis-(1-propyl-1H-benzimidazol-2-yl)-2-oxopropane ligands in a distorted octa-hedral coordination environment. There are significant differences in the chemically equivalent Cd-O bond lengths [2.618 (2) Å and 2.561 (2) Å].
Stress ethylene production in bean (Phaseolus vulgaris L., cv. Taylor's Horticultural) leaf tissue was stimulated by Cd(2+) at concentrations above 1 micromolar. Cd(2+)-induced ethylene biosynthesis was dependent upon synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) by ACC synthase. Activity of ACC synthase and ethylene production rate peaked at 8 h of treatment. The subsequent decline ...
The aim of this study was to adapt MARMS with some modifications to detect beta mutation in our cohort of thalassemia patients. We focused only on transfusion-dependent thalassemia Malay patients, the predominant ethnic group (95%) in the Kelantanese population. Eight mutations were identified in 46 out of 48 (95.83%) beta thalassemia alleles. Most of the patients (54.2%) were compound heterozy...
The title compound, [Cd(C(5)H(3)N(2)O(2))(N(3))](n), has been pre-pared by the reaction of pyrazine-2-carboxylic acid, cadmium(II) nitrate and sodium azide. In the structure, the Cd(II) atom is six-coordinated by two azide anions and three pyrazine-2-carboxyl-ate ligands. Each pyrazine-2-carboxyl-ate ligand bridges three Cd(II) atoms, whereas the azide ligand bridges two Cd(II) atoms, resulting...
The distribution and chemical behavior of Cd(2+) in tissues and its chemical form in xylem water of soybean plants (cv. Williams) were investigated. Following root absorption, Cd is strongly retained by roots, with only 2% of the accumulated Cd being transported to leaves; as much as 8% was transported to seeds during seed filling. In vivo xylem exudates contained two anionic Cd complexes in ad...
The asymmetric unit of the title compound, [Cd(NCS)(2)(C(5)H(5)N)(2)](n), consists of two crystallographically independent Cd(II) cations, four thio-cyanato anions and four pyridine ligands. The Cd(II) atoms are each coordinated by four N atoms from two pyridine ligands and two thio-cyanato anions, each in a mutually cis orientation, and by two S atoms from two adjacent thio-cyanato anions with...
BACKGROUND AND AIMS Ficolin-2 is an acute phase reactant produced by the liver and targeted to recognize N-acetyl-glucosamine which is present in bacterial and fungal cell walls. We recently showed that ficolin-2 serum levels were significantly higher in CD patients compared to healthy controls. We aimed to evaluate serum ficolin-2 concentrations in CD patients regarding their correlation with ...
