Buzzing through the blood-brain barrier

Posted by in categories: biotech/medical, neuroscience

UConn engineers have designed a non-toxic, biodegradable device that can help medication move from blood vessels into brain tissues —a route traditionally blocked by the body’s defense mechanisms. They describe their invention in the 23 December issue of PNAS.

Blood vessels in the are lined by cells fitted together tightly, forming a so-called , which walls off bacteria and toxins from the brain itself. But that blood-brain also blocks medication for brain diseases such as cancer.

“A safe and effective way to open that barrier is ultrasound,” says Thanh Nguyen, a biomedical engineer at UConn. Ultrasonic waves, focused in the right place, can vibrate the cells lining enough to open transient cracks in the blood-brain barrier large enough for medication to slip through. But the current ultrasound technology to do this requires multiple ultrasound sources arrayed around a person’s skull, and then using an MRI machine to guide the person operating the ultrasounds to focus the waves in just the right place. It’s bulky, difficult, and expensive to do every time a person needs a dose of medication.

Mom With Brain Tumor Turns To Boston Hospital For Keyhole Brain Surgery

Posted by in categories: biotech/medical, neuroscience

(CBS) — Imagine giving birth to a premature baby and then being told you have a brain tumor. That’s what happened to a woman from Holden. But thanks to a new approach at Brigham and Women’s Hospital, this new mom was able to have brain surgery and quickly return to her newborn son.

At 27 weeks pregnant, Bethany Shea was diagnosed with preeclampsia and had an emergency C-section. Then she went blind.

“It was a pregnancy complication due to my high blood pressure,” Bethany explained.

At Roswell we have developed the first Molecular Electronics chip. We utilized advances in semiconductor technology, nano-fabrication and bio-sensors to create standard CMOS chips that directly integrate sensor molecules into the CMOS integrated circuits.

Going “on-chip” to deploy bio-sensors provides unprecedented economics, precision, portability, and scalability. Our first chip is designed to read DNA; future chips will be designed for protein detection and other diverse bio-sensing applications.

Move Your Body, Bolster Your Brain

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

“A hormone that is released during exercise may improve brain health and lessen the damage and memory loss that occur during dementia, a new study finds. The study, which was published this month in Nature Medicine, involved mice, but its findings could help to explain how, at a molecular level, exercise protects our brains and possibly preserves memory and thinking skills, even in people whose pasts are fading.”


Exercise doesn’t just strengthen your muscles, it can also be good for your mind and memory. Fitness advice from the year in Well.

Chinese gene-editing scientist jailed for 3 years

Posted by in categories: biotech/medical, genetics, law enforcement

A Chinese scientist who helped create the world’s first gene-edited babies has been sentenced to three years in prison.

He Jiankui shocked the world in 2018 when he announced that twin girls Lulu and Nana had been born with modified DNA to make them resistant to HIV, which he had managed using the gene-editing tool CRISPR-Cas9 before birth.

He, an associate professor at the Southern University of Science and Technology in Shenzhen, said at the time that he was “proud” of the achievement. He later claimed that a second woman was pregnant as a result of his research.

Cancer Cells Switch Sugar for Fatty Acids to Spread Around the Body

Posted by in categories: biotech/medical, food

Scientists have uncovered a crucial change in cancer cells that allows them to spread around the body – by switching from sugar to fatty acids to fuel their growth.

Changing their ‘diet’ in this way allows tumour cells to set up shop at new sites where resources such as glucose – their preferred food source – are limited.

Researchers at The Institute of Cancer Research, London, found that a protein called AKR1B10 helps cells adapt the ways in which they get their energy.
