Sulfhemoglobin is formed by the irreversible bonding of sulfur atoms to heme molecule. Oxygen then unable bind molecule, rendering hemoglobin molecule carry oxygen. The most common etiology sulfhemoglobinemia use/misuse sulfur-containing medications such as AZO. Unlike methemoglobin, sulfhemoglobin, due its binding, has no antidote, and treatment ultimately supportive. We present a case 53-year...

Background: Nitric Oxide (NO) is a very important signaling molecule which acts as regulator of many physiological processes in tissues including epithelial cell gastrointestinal tract. In this study we investigated the effects L-Arginine NO progenitor and L-NAME inhibitor on number height Jejunum female rats.

Objective(s): First-principles calculations have been carried out to investigate the interaction of aspirin molecule with nitrogen-doped TiO2 anatase nanoparticles using the density functional theory method in order to fully exploit the biosensing capabilities of TiO2 particles. Methods: For this purpose, we have mainly studied the a...

A numerical study is presented to investigate the electronic transport properties through a synthetic DNA molecule based on a quasiperiodic arrangement of its constituent nucleotides. Using a generalized Green's function technique, the electronic conduction through the poly(GACT)-poly(CTGA) DNA molecule in a metal/DNA/metal model structure has been studied. Making use of a renormalization schem...

serum ige assay is a mainstay step in the allergy work up. allergenic extracts and molecular components are available at present. this real life study compared the serum specific ige levels against allergenic extracts with allergenic molecules in patients allergic to parietaria, betulaceae , and mites. this retrospective real life study included 489 subjects with respiratory allergy. inclusion ...

Nitric oxide (NO), an endogenous signaling molecule, is involved in various physiological processes and stress responses in plants. In the present research, Pyrodwarf pear (Pyrus communis) rootstocks were grown by nutrient solution to investigate the effects of sodium nitroprusside (SNP) application as an NO donor at 0, 0.1, 0.5, and 1 mM levels on plant stress tolerance, content of ma...

Deuterium labelling is used to show that the disproportionation of thioxanthylium salts involve transfer of a hydride, (deuteride) ion from the9-positionof one molecule of the compound, as its hydro], to the 9 - position of another molecule in the cation form
