Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, potentially fatal condition caused when bloodclots in the lungs block blood vessels to the heart. Yale PCCSM’s Phillip Joseph, MD, and Yale Cardiac Surgery’s Prashanth Vallabhajosyula, MD, share how Yale’s highly specialized #

CHICAGO, Feb 19 (Reuters) — A study that analyzed the genetic code of a quarter of a million U.S. volunteers found more than 275 million entirely new variants that may help explain why some groups are more prone to disease than others, researchers reported on Monday.
The whole genome sequencing data from a wide range of Americans aims to address the historical lack of diversity in existing genomic datasets by focusing on previously under-represented groups. The U.S. National Institutes of Health-funded “All of Us” study turned up 1 billion genetic variants in total.
“Sequencing diverse populations can lead to new drug targets that are relevant to everyone,” said Dr. Josh Denny, a study author and its chief executive. “It can also help uncover disparities that lead to specific treatments for people that are experiencing higher burdens of disease or different disease.”
A new study led by Stanford Medicine scientists demonstrates a simple way of studying organ aging by analyzing distinct proteins, or sets of them, in blood, enabling the prediction of individuals’ risk for diseases.
To synthesize potential drugs or natural products, you need natural substances in specific mirror-image variants and with a high degree of purity. For the first time, chemists at the University of Bonn have succeeded in producing all eight possible variants of polypropionate building blocks from a single starting material in a relatively straightforward process. Their work has now been published in Angewandte Chemie International Edition.
Polypropionates are natural products that can help save lives. They are needed to make reserve antibiotics, compounds that are only ever used to treat infections caused by drug-resistant bacteria. In nature, chiral compounds exist in two different variants that share the same molecular formula but are mirror images of each other, like a right and a left hand. Chemists call this “chirality,” which literally means “handedness.”
“What’s interesting is that the mirror-image forms can have very different properties,” explains Professor Andreas Gansäuer from the Kekulé Institute of Organic Chemistry and Biochemistry at the University of Bonn. “One well known example is undoubtedly carvone. The dextro-, or ‘right-handed,’ form of this molecule smells of caraway, while its levo-, or ‘left-handed,’ form is what gives peppermint its distinctive odor.”
