As an anti-inflammatory, dapsone inhibits the myeloperoxidase-H 2 O 2-halide-mediated cytotoxic system in polymorphonucleocytes. [50] As part of the respiratory burst that neutrophils use to kill bacteria, myeloperoxidase converts hydrogen peroxide (H 2 O 2) into hypochlorous acid (HOCl). HOCl is the most potent oxidant generated by neutrophils ...
Silver selenide has two crystal phases on the bulk phase diagram. At lower temperatures, it has an orthorhombic structure, β-Ag 2 Se. This orthorhombic phase, stable at room temperature, is a narrow-gap semiconductor, with space group P2 1 2 1 2 1. The exact size of the band gap has been given variously from 0.02 eV to 0.22 eV. [4]
Unlike a spirit duplicator master, a hectograph master is not a mirror image. Thus, when using a spirit duplicator master with a hectograph, one writes on the back of the purple sheet, using it like carbon paper to produce an image on the white sheet, rather than writing on the front of the white sheet to produce a mirror image on its back.
Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and serves as a visual framework for hanging details of the entire atomic structure ...
A hydrocolloid dressing is biodegradable, [2] breathable, and depending on the dressing selected, may adhere to the skin, so no separate taping is needed. [ 3 ] The active surface of the dressing is coated with a cross-linked adhesive mass containing a dispersion of gelatin, pectin and carboxymethyl cellulose together with other polymers and ...
[1] [2] It is a type of zone electrophoresis usually performed on proteins in a gel that takes advantage of the fact that overall charge on the molecule of interest is a function of the pH of its surroundings. [3]
1,1-Dichloroethylene, commonly called vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula CCl 2 CH 2.It is a colorless liquid with a sharp odor. Like most chlorocarbons, it is poorly soluble in water but soluble in organic solvents. 1,1-DCE was the precursor to the original clingwrap, Saran, for food, but this application has been phased
1,2-Indandione is an organic compound with the molecular formula C 6 H 4 (CO) 2 CH 2. A yellow solid, it is classified as a vicinal diketone on an indane framework. [1] 1,2-Indandione is used in the first stage of forensic identification of latent fingerprints. It is particularly useful for paper, and for items printed with thermal inks such as ...
