Newly discovered heart molecule could lead to effective treatment for heart failure
Researchers have discovered a previously unknown cardiac molecule that could provide a key to treating, and preventing, heart failure.
The newly discovered molecule provides the heart with a tool to block a protein that orchestrates genetic disruptions when the heart is subjected to stress, such as high blood pressure.
When the research team, led by Ching-Pin Chang, M.D., Ph.D., associate professor of medicine at the Indiana University School of Medicine, restored levels of the newly discovered molecule in mice experiencing heart failure, the progression to heart failure was stopped. The research was published in the online edition of the journal Nature.
The newly discovered molecule is known as a long non-coding RNA. RNA’s usual role is to carry instructions — the code — from the DNA in a cell’s nucleus to the machinery in the cell that produces proteins necessary for cell activities. In recent years, scientists have discovered several types of RNA that are not involved in protein coding but act on their own. The role in the heart of long non-coding RNA has been unknown.

Complete Cardiac Transplant. (Warning: Graphic and not safe for work)

My friend, old and passing, said,
“There is more to life than staying alive.
Don’t rescue me too much.”
On his farm, twelve miles out
by rough gravel roads, he is done
with plowing, spraying, harvesting.
But he is not done watching the sun
sink below the windbreak or listening
to the nighthawks above his fields.
Don’t make him move to town.
There is more to tragedy
than dying.

Rod of Asclepius.
Just received my Pencil from Fifty Three for the app Paper. This is my first drawing with it.
The Rod of Asclepius is a serpent-entwined rod wielded by the Greek god Asclepius, a deity associated with healing and medicine.

Modified measles virus destroys cancer in early clinical trial

Promising early results from a clinical trial at the Mayo Clinic out this week suggest that a modified version of the measles virus can be used to target cancer cells and put the condition into remission.

Cardiac Conduction Study.

  • SA: Sinoatrial node
  • AIT: Anterior internodal tract
  • MIT: Middle internodal tract
  • PIT: Posterior internodal tract
  • BB: Bachmann’s bundle
  • AV: Atrioventricular node
  • BH: Bundle of His
  • RB: Right bundle branch
  • LB: Left bundle branch
  • CP: Conduction pathways

In order to produce an efficient contraction to pump blood, the heart relies upon its electrical conduction system to synchronize its actions between the four chambers.

CS: Coronary sinus
RA: Right atrium
O: Oblique vein of left atrium
SC: Small cardiac vein
MC: Middle cardiac vein
LPV: Left posterior ventricular vein
LM: Left marginal vein
GC: Great cardiac vein
