Japanese Scientists Use Pluripotent Cells to Create Functional Liver Tissue

stem-cells

Japanese scientists have been able to induce stem cells to create liver-like tissue in a dish. The new findings were reported online by the journal Nature, but the scientists have yet to publish their findings. Once the achievement is accomplished, there could be several big clinical implications. This could mean that it would be possible to coax stem cells to organize into functional organs for transplantation.

New Drug CD47 Could Potentially Shrink and Cure All Tumors

cd47-cancer-antibody-drug

New research points that there could be a single drug that could shrink or cure all types of cancer, whether it’s breast, ovary, colon, bladder, brain, or liver. The treatment uses an antibody that blocks the ‘do not eat’ signal that’s usually displayed on tumor cells and coaxes the immune system to destroy cancer cells.

Flu Infections and MRSA Combine into Lethal Cocktail in Maryland

MRSA-pneumonia

MRSA, methicillin-resistant Staphylococcus aureus can be even deadlier when it is combined with a virulent flu infection. It’s been reported that a family of five have fallen ill and three have died from MRSA pneumonia that took hold in the lungs and was inflamed by a flu infection.

Transplants Without the Need for Lifelong Immunosupression

immunosuppressant-free-transplant

As a result of organ transplantation, patients need to take a lifelong regimen of immunosuppressors to fight off graft-versus-host disease (GvHD), which is common and often deadly. Now, researchers have been able to completely replace people’s bone-marrow-derived stem cells with those from unrelated donors without causing GvHD. This means that the recipients could also accept kidneys from the same donors without the need of immunosuppressors.

Light-Switched Anesthetics Allow Researchers to turn Pain Nerves On and Off

sodium-channel-cell

A new study published in the journal Nature Methods, shows that a novel local anesthetic developed by a group of researchers at UC Berkeley, University of Münich, and the Université de Boardeaux, can be switched on and off using different wavelengths of light, allowing a much finer control of which nerves are blocked.

Exploding Carbon Nanotubes Could Work as Drug-Based Delivery Devices

exploding-carbon-nanotubes

Carbon nanotubes can be used in a variety of different contexts. Most recently, tubes were filled with drugs and sealed with biodegradable caps, allowing them to work inside cells, where they delivered their loads. There has been some concern that these nanotubes might not target the drugs well enough, which is why researchers at the University of Rochester in New York State have come up with exploding carbon nanotubes.
