Red, red wine
The cardiovascular benefits of drinking red wine are well known but far less well known are the mechanisms behind this effect. A new study into red wine polyphenols has suggested that they may be helping to protect omega-3 fatty acids from breaking down in the body.1

Red wine is a natural source of polyphenols, a group of chemicals associated with decreased risk of cardiovascular disease, cancer and other chronic illnesses. A study, published in Food Research International, has investigated the effects of the polyphenols from red wine on the human plasma fatty acids and their oxidization, particularly looking at those involved in the inflammatory response.
The oxidizability of the major fatty acids in plasma was determined by measuring their deterioration by gas chromatography. The study found that the polyphenols increased the resistance to peroxidation of the omega-3 fatty acids involved in the inflammatory response compared with omega-6 acids. It was suggested that the results could show the wine polyphenols are making the acids less accessible to hydro-soluble radicals, providing a biochemical rationale for future studies on these potential health benefits.

AI and GenAI Applications to Help Optimize Purification and Yield of Antibodies From Plasma
October 31st 2024Deriving antibodies from plasma products involves several steps, typically starting from the collection of plasma and ending with the purification of the desired antibodies. These are: plasma collection; plasma pooling; fractionation; antibody purification; concentration and formulation; quality control; and packaging and storage. This process results in a purified antibody product that can be used for therapeutic purposes, diagnostic tests, or research. Each step is critical to ensure the safety, efficacy, and quality of the final product. Applications of AI/GenAI in many of these steps can significantly help in the optimization of purification and yield of the desired antibodies. Some specific use-cases are: selecting and optimizing plasma units for optimized plasma pooling; GenAI solution for enterprise search on internal knowledge portal; analysing and optimizing production batch profitability, inventory, yields; monitoring production batch key performance indicators for outlier identification; monitoring production equipment to predict maintenance events; and reducing quality control laboratory testing turnaround time.
