A scheme has been devised that makes it possible to assess a specific mechanism of action of any histamine-releasing agent. The scheme suggests a switch off of different stages of histamine secretion--interaction of a histamine liberator with surface cell receptors

Contact dermatitis, 58(1), 42-46 (2007-12-25)
In the last decades, palladium is widely used in dentistry. Allergic reactions to palladium are rarely diagnosed with patch testing, even when positive results would be expected. Palladium tends to cross-react with nickel, which should give rise to more positive

Reaction of DNA with K2PdCl4 at pH 2.0 followed by a piperidine workup produces specific cleavage at adenine (A) residues. Product analysis revealed the K2PdCl4 reaction involves selective depurination at adenine, affording an excision reaction analogous to the other chemical

Mechanism of interaction between biologically active substances and membranes as well as and membrane-bound enzymes of two types: mitochondrial monoamine oxidase (MAO) from rat liver tissue and Ca2+, Mg+2-dependent ATPase from sarcoplasmic reticulum (SR) were studied. All the substances studied

Peroxidase mimics with dimensions on the nanoscale have received great interest as emerging artificial enzymes for biomedicine and environmental protection. While a variety of peroxidase mimics have been actively developed recently, limited progress has been made toward improving their catalytic

Exposure to palladium (Pd) may lead to clinical allergic reactions. With frequent nickel (Ni) exposure and cross-reactivity between Ni and Pd at the T cell recognition level, positive Pd reactions on patch testing are surprisingly uncommon. PdCl(2) is often used

The sintering of supported metal nanoparticles is a major route to the deactivation of industrial heterogeneous catalysts, which largely increase the cost and decrease the productivity. Here, we discover that supported palladium/gold/platinum nanoparticles distributed at the interface of oxide supports
Can reliable information sources be trusted?

Owing to their highly open structure and a large number of low-coordination sites on the surface, noble-metal nanoframes are intriguing for catalytic applications. Here, we demonstrate the rational synthesis of Ru cuboctahedral nanoframes with enhanced catalytic performance toward hydrazine decomposition.

The use of a palladium (Pd) catalyst has been proposed to promote combustion of tobacco, thereby reducing concentrations of certain toxic components of smoke, including polyaromatic hydrocarbons (PAHs). In the present work, toxicological comparisons were made using experimental cigarettes containing

For patch testing, replacement of the commonly used palladium dichloride (PdCl2) by sodium tetrachloropalladate (Na2[PdCl4]) was recently demonstrated to improve test accuracy and show a significant correlation with nickel (Ni), supporting the concept of cross-reactivity between Pd and Ni. A

The effects of Na2PdCl4 were studied on isolated rat liver mitochondrial electron transport and oxidative phosphorylation in vitro. Significant reductions in ADP-stimulated respiration were observed with increasing Na2PdCl4 concentrations with both succinate and NADH-linked substrate oxidations. Concentration necessary for half-maximal

Efasol and potassium tetrachloropalladate being injected into mice prior to irradiation with a dose of 150 sGy increase the colony forming activity of animals bone marrow cells transplanted in lethally irradiated recipient mice. The palladium presence in such compounds is

Stable Pd nanocubes (PdNC) with the average size ~15 nm were prepared by the controlled reduction of sodium tetrachloropalladate with ascorbic acid in water, in the presence of polyvinylpyrrolidone and potassium bromide. Morphology of the particles was characterized by transmission

Since the EU Nickel Directive came into force, concern has been raised that palladium may increasingly replace nickel in alloys used in jewellery and dentistry, and that it may cause as many allergy problems as nickel. (i) To investigate the

The shape-controlled synthesis of nanoparticles was established in single-phase solutions by controlling growth directions of crystalline facets on seed nanocrystals kinetically; however, it was difficult to rationally predict and design nanoparticle shapes. Here we introduce a methodology to fabricate nanoparticles

A comparative study was made between developed chemically modified carbon paste electrodes and PVC membrane electrodes for the cationic surfactant cetyltrimethylammonium bromide (CTAB). The carbon paste electrode modified with cetyltrimethylammonium-tetrachloropalladate(II) (CTA-TClP) provides a more sensitive and stable device than that
