From quantitative electron-microscope observations on the binding of permanganate to regions of erythrocytes and reticulocytes of known chemical composition, it is concluded that KMnO4, like phosphotungstic acid (PTA), binds preferentially to sites on proteins. Compared with PTA, KMnO4 binding exhibits less anomalous behaviour. The data support the hypothesis previously put forward that the 2 r...

BACKGROUND: The conventional solution-phase Chemical Cleavage of Mismatch (CCM) method is time-consuming, as the protocol requires purification of DNA after each reaction step. This paper describes a new version of CCM to overcome this problem by immobilizing DNA on silica solid supports. RESULTS: DNA test samples were loaded on to silica beads and the DNA bound to the solid supports underwent ...

Small- and large-scale accidents often occur in workplaces handling hazardous chemical substances. These are usually caused by leaks, explosions, fires complex chemicals; a large proportion of these leaks. A release accident that injured four people occurred during an optical film-manufacturing process. This report analyzes the causes this provides effective measures for prevention. was abnorma...

The case presented in this report is one of 45-year-old female with dysphagia and swelling in the neck since 2 months, breathlessness, history of inability to open the mouth and course of events resembled scleroderma and diagnosis of primary systemic amyloidosis could not be established until autopsy. At autopsy skin, oesophagus, salivary glands, tongue and all the parenchymal organs like splee...

Photocatalytic H2O2 production is an innovative on-site synthesis method to treat organic pollutants through Fenton-like reactions, avoiding the need and potential liability of storage transportation. Accurate quantification crucial explore mechanism photocatalytic optimize reaction parameters. In this work, three common methods (i.e., titration with potassium permanganate (KMnO4), colorimetry ...

Siderite (FeCO3) is commonly found in coal overburden and, when present, can cause interference in the determination of neutralization potential (NP). Under acidic testing conditions, FeCO3 reacts to neutralize acid, which contributes to the NP. However, continued weathering of FeCO3 (oxidation of Fe 21 and hydrolysis of Fe) produces a neutral to slightly acidic solution. The effects of hydroge...

The chemical probes potassium permanganate (KMnO4) and diethylpyrocarbonate (DEPC) can be used to study the conformational flexibility of short tracts of adenine (A-tracts) present in DNA. With these probes, we demonstrate that a novel distortion is induced in a 5 base pair A-tract at low temperature. Formation of this distorted A-tract structure, which occurs in a DNA fragment from the promote...

Four pharmaceuticals (ranitidine, nizatidine, doxylamine, and carbinoxamine) were selected as model compounds to assess the efficiency of four oxidants (ozone (O3), chlorine (Cl2), chlorine dioxide (ClO2) and potassium permanganate (KMnO4)) on the removal of amine-based pharmaceutical and personal care products (PPCPs), as well as the reduction of their N-Nitrosodimethylamine formation potentia...
