[Detoxication of methanal preserved bioprostheses]
Zeitschrift Fur Experimentelle Chirurgie
|June 1, 1982
Abstract:
The substitutes could be decontaminated by means of six to eight times soaking into sterile sodium chloride solution (154 mmol/l = 9 g/l) in each case half an hour if a short preparation time for the implantation of protein cross-linked and methanal storaged bioprotheses is existent. This procedure must be carried out under strict aseptic conditions. A microbial recontamination of the preparations threats moreover.

01:19Masking and Demasking Agents
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...

01:17Phase II Reactions: Methylation Reactions
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
