Mitochondria transplants could cure diseases and lengthen lives (economist.com)
Organ transplants are a familiar idea. Organelle transplants, less so. Yet organelles are to cells what organs are to bodies—specialised components that divvy up the labour needed to keep the whole thing ticking over. Swapping old organelles for new in cells where the machinery has switched from ticking to tocking thus makes sense in principle. And, for one type of organelle, that principle is now being tested in practice.

Some gut bacteria could make certain drugs less effective, study indicates (phys.org)
A study published in Nature Chemistry by researchers from the University of Pittsburgh and Yale University shows how common gut bacteria can metabolize certain oral medications that target cellular receptors called GPCRs, potentially rendering these important drugs less effective.

Pink Skies (ist.ac.at)
Organoids have revolutionized science and medicine, providing platforms for disease modeling, drug testing, and understanding developmental processes. While not exact replicas of human organs, they offer significant insights. The Siegert group at the Institute of Science and Technology Austria (ISTA) presents a new organoid model that reveals details of the developing nervous system’s response to viral infections, such as Rubella. This model could influence pharmaceutical testing, particularly benefiting drug safety for pregnant women.

Excitable cells (jenevoldsen.com)
I wrote this post to answer some of the questions, I had as a medical student, when I first learned about cardiac arrhythmias. Mainly, what are the conditions required to initiate and maintain a reentrant arrhythmia? That is, a state where the heart muscles are continuously activated by a self-sustaining loop, independent of the normal pace-making system. These arrhythmias can be benign, as with AV-nodal reentry tachycardia (AVNRT); a common, and usually harmless, cause of palpitations in young people.

The Mysterious Flow of Fluid in the Brain (quantamagazine.org)
Encased in the skull, perched atop the spine, the brain has a carefully managed existence. It receives only certain nutrients, filtered through the blood-brain barrier; an elaborate system of protective membranes surrounds it. That privileged space contains a mystery. For more than a century, scientists have wondered: If it’s so hard for anything to get into the brain, how does waste get out?

Hair loss drug finasteride can cause debilitating side-effects, men say (cbc.ca)
For decades, millions of men around the world have turned to a drug — finasteride, or Propecia, its most well-known brand name — to slow hair loss. But an increasing number of experts are sounding the alarm that this medication can cause rare but serious side-effects, which can persist after stopping treatment.

Metformin-regulated glucose flux from the circulation to the intestinal lumen (nature.com)
Through a retrospective analysis of existing FDG PET-MRI images, we recently demonstrated that metformin increases the accumulation of FDG in the intestinal lumen, suggesting that metformin stimulates glucose excretion into the intestine. However, the details of this phenomenon remain unclear. We here investigate the detailed dynamics of intestinal glucose excretion, including the rate of excretion and the metabolism of excreted glucose, in both the presence and absence of metformin.
