A team of scientists has developed an electrochemical technique that enables precise, para-position single-carbon insertion into polysubstituted pyrroles. This advancement holds significant promise for synthetic organic chemistry, particularly in the development of pharmaceutical compounds.
Their work was recently published in the Journal of the American Chemical Society.
“We set out to address the longstanding challenge of achieving single-carbon insertion into aromatic rings with precise positional control,” said Mahito Atobe, Professor, Faculty of Engineering, Yokohama National University.
According to new research, communication between the gut and the brain is sophisticated enough to be classed as a new and distinct sense – one capable of affecting our appetite and even our mood.
This two-way link has previously been associated with a variety of health issues, though the physical processes at work have never been clearly identified.
Building on what we already know about our digestive and neurological systems, a team from Duke University in the US traced a series of biochemical actions from the digestive tracts of mice to their brains.
Vanderbilt University Medical Center researchers have developed a groundbreaking new method for the recovery of hearts from deceased organ donors after circulatory death (DCD). The method (rapid recovery with extended ultra-oxygenated preservation [REUP]), which involves flushing the donor heart with a cold oxygenated preservation solution after death, avoids the disadvantages of two existing preservation methods, both of which reanimate the heart, one that has ethical questions and another that
