Investigating how ‘chemo brain’ develops in cancer patients

Posted by in categories: biotech/medical, neuroscience

Interesting read on Chemo’s impact on the brain and brain functioning known as Chemo Brain.


During and after chemotherapy, many cancer patients describe feeling a mental fog, a condition that has been dubbed “chemo brain.” Why this happens is unclear, but researchers have found a new clue to understanding this syndrome. A study in the journal ACS Chemical Neuroscience reports that chemotherapy in rats affects their chemical messengers dopamine and serotonin, which are associated with cognition.

Purely tragic. Hopefully, doctors without borders or experts can assist this child.


A baby boy’s head has swollen to more than three times its normal size due to a medical condition.

Israeli firms develop high-speed 3D printer for stem cells

Posted by in categories: 3D printing, biotech/medical

3D Stem Cells — definitely makes sense given the organ, skin graffe, etc. produce on 3D printers in today’s labs.


JERUSALEM – Israeli 3D printer firm Nano Dimension has successfully lab-tested a 3D bioprinter for stem cells, paving the way for the potential printing of large tissues and organs, the company said on Wednesday.

While 3D printers are used already to create stem cells for research, Nano Dimension said the trial, conducted with Israeli biotech firm Accellta Ltd, showed its adapted printer could make large volumes of high resolution cells quickly.

Engineers take first step toward flexible, wearable, tricorder-like device

Posted by in categories: biotech/medical, chemistry, computing, electronics, engineering, mobile phones, wearables

Engineers at the University of California San Diego have developed the first flexible wearable device capable of monitoring both biochemical and electric signals in the human body. The Chem-Phys patch records electrocardiogram (EKG) heart signals and tracks levels of lactate, a biochemical that is a marker of physical effort, in real time. The device can be worn on the chest and communicates wirelessly with a smartphone, smart watch or laptop. It could have a wide range of applications, from athletes monitoring their workouts to physicians monitoring patients with heart disease.

Nanoengineers and electrical engineers at the UC San Diego Center for Wearable Sensors worked together to build the device, which includes a flexible suite of sensors and a small electronic board. The device also can transmit the data from biochemical and electrical signals via Bluetooth.

Nanoengineering professor Joseph Wang and electrical engineering professor Patrick Mercier at the UC San Diego Jacobs School of Engineering led the project, with Wang’s team working on the patch’s sensors and chemistry, while Mercier’s team worked on the electronics and data transmission. They describe the Chem-Phys patch in the May 23 issue of Nature Communications.

Gene helps prevent heart attack, stroke; may also block effects of aging

Posted by in categories: biotech/medical, life extension

May turn out to be the “fountain-of-youth gene,” say researchers.

University of Virginia School of Medicine have discovered that a gene called Oct4 — which scientific dogma insists is inactive in adults — actually plays a vital role in preventing ruptured atherosclerotic plaques inside blood vessels, the underlying cause of most heart attacks and strokes.

Researchers identify genes linked to the effects of mood and stress on longevity

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

The visible impacts of depression and stress that can be seen in a person’s face—and contribute to shorter lives—can also be found in alterations in genetic activity, according to newly published research.

In a series of studies involving both C. elegans worms and human cohorts, researchers from the Indiana University School of Medicine and the Scripps Research Institute have identified a series of genes that may modulate the effects of good or bad mood and response to stress on lifespan. In particular, the research pointed to a gene known as ANK3 as playing a key role in affecting . The research was published May 24, 2016 in the Nature Publishing Group journal Molecular Psychiatry, the top ranked journal in the field of psychiatry.

“We were looking for genes that might be at the interface between mood, stress and longevity”, said Alexander B. Niculescu III, M.D., Ph.D., professor of psychiatry and medical neuroscience at the IU School of Medicine. “We have found a series of genes involved in mood disorders and stress disorders which also seem to be involved in longevity.
