New Method of 3D-Printing Soft Materials Could Jump-Start Creation of Tiny Medical Devices for the Body

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

Researchers at the National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as drug delivery systems or flexible electrodes that can be inserted into the human body.

A standard 3D printer makes solid structures by creating sheets of material — typically plastic or rubber — and building them up layer by layer, like a lasagna, until the entire object is created.

Using a 3D printer to fabricate an object made of gel is a “bit more of a delicate cooking process,” said NIST researcher Andrei Kolmakov. In the standard method, the 3D printer chamber is filled with a soup of long-chain polymers — long groups of molecules bonded together — dissolved in water. Then “spices” are added — special molecules that are sensitive to light. When light from the 3D printer activates those special molecules, they stitch together the chains of polymers so that they form a fluffy weblike structure. This scaffolding, still surrounded by liquid water, is the gel.

The Road to Human 2.0

Posted by in categories: 3D printing, biotech/medical, computing, genetics, life extension, nanotechnology, neuroscience, transhumanism

In the coming 2020s, the world of medical science will make some significant breakthroughs. Through brain implants, we will have the capability to restore lost memories.

~ The 2020s will provide us with the computer power to make the first complete human brain simulation. Exponential growth in computation and data will make it possible to form accurate models of every part of the human brain and its 100 billion neurons.

~ The prototype of the human heart was 3D printed in 2019. By the mid- 2020s, customized 3D- printing of major human body organs will become possible. In the coming decades, more and more of the 78 organs in the human body will become printable.

‘Young’ microbiota can reverse ageing of the immune system and boost vaccines

Posted by in categories: biotech/medical, life extension

Every human being is home to trillions of microbes that are collectively known as the microbiota. Recent research into how these microbes affect the immune system may explain why older people are more vulnerable to disease and suggest ways to tackle that vulnerability.

Scientists at The University of Edinburgh’s Roslin Institute, led by Professor Neil Mabbott, discovered that as mice get older they showed a marked decrease in the number of M cells found in the lining of the gut. These are specialised cells that look out for infections and trigger the early stages of the immune response. Fewer M cells means a weaker immune system. At the same time, the researchers found that the older mice had depleted microbiota compared to younger mice. The microbiota were less diverse and certain species known to decrease inflammation of the gut in humans were missing.

New nanotechology design provides hope for personalized vaccination for treating cancer

Posted by in categories: biotech/medical, chemistry, nanotechnology

One of the key challenges in developing effective, targeted cancer treatments is the heterogeneity of the cancer cells themselves. This variation makes it difficult for the immune system to recognize, respond to and actively fight against tumors. Now, however, new advances in nanotechnology are making it possible to deliver targeted, personalized “vaccines” to treat cancer.

A new study, published on October 2, 2020 in Science Advances, demonstrates the use of charged nanoscale metal-organic frameworks for generating free radicals using X-rays within tumor tissue to kill directly. Furthermore, the same frameworks can be used for delivering immune signaling molecules known as PAMPs to activate the immune response against . By combining these two approaches into one easily administered “vaccine,” this new technology may provide the key to better local and systemic treatment of difficult-to-treat cancers.

In a collaboration between the Lin Group in the University of Chicago Department of Chemistry and the Weichselbaum Lab at University of Chicago Medicine, the research team combined expertise from inorganic chemistry and to tackle the challenging problem of properly targeting and activating an innate immune response against . This work leveraged the unique properties of nanoscale metal-organic frameworks, or nMOFs —nanoscale structures built of repeating units in a lattice formation that are capable of infiltrating tumors.

Researchers discover a rare genetic form of dementia

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

A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain—which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer’s Disease—that could be targeted for new therapies. The study was published today in Science.

Alzheimer’s (AD) is a neurodegenerative disease characterized by a buildup of proteins, called , in certain parts of the brain. Following an examination of human brain tissue samples from a deceased donor with an unknown neurodegenerative disease, researchers discovered a novel mutation in the Valosin-containing protein (VCP) gene in the brain, a buildup of tau proteins in areas that were degenerating, and neurons with empty holes in them, called vacuoles. The team named the newly discovered disease Vacuolar Tauopathy (VT)—a neurodegenerative disease now characterized by the accumulation of neuronal vacuoles and tau protein aggregates.

“Within a cell, you have proteins coming together, and you need a process to also be able to pull them apart, because otherwise everything kind of gets gummed up and doesn’t work. VCP is often involved in those cases where it finds proteins in an aggregate and pulls them apart,” Edward Lee, MD, Ph.D., an assistant professor of Pathology and Laboratory Medicine in the Perelman School of Medicine at the University of Pennsylvania. “We think that the mutation impairs the proteins’ normal ability to break aggregates apart.”

Surprising Brain Area Linked to Short-Term Memory

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

Researchers at Rockefeller University have just released findings from a new study, done in mice, which identifies a gene that is critical for short-term memory but functions in a part of the brain not traditionally associated with memory. Classical models for short-term memory typically assume that all neuronal activity is contained within the prefrontal cortex (PFC), yet, data from this new study suggests that a G-protein coupled receptor in the thalamus may play a large role. Data from the study was published recently in Cell through an article titled “A Thalamic Orphan Receptor Drives Variability in Short Term Memory.”

Interestingly, in order to discover new genes and brain circuits that are important for short-term memory, the researchers turned to studying genetically diverse mice, rather than inbred mice commonly used in research.

“We needed a population that is diverse enough to be able to answer the question of what genetic differences might account for variation in short-term memory,” explained co-senior study investigator Praveen Sethupathy, PhD, an associate professor of biomedical sciences in Cornell’s College of Veterinary Medicine and director of the Cornell Center for Vertebrate Genomics.
