Neuroscientists identify a reversible biological mechanism behind drug-induced cognitive deficits
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
Researchers found that methamphetamine and PCP cause a phenomenon known as neurotransmitter switching, impairing memory. This change is reversible, pointing to potential treatments for drug-induced cognitive deficits and related neuropsychiatric conditions.

Ion Superhighways: The Nanotech Breakthrough Powering Tomorrow’s Tech
Posted by Genevieve Klien in categories: energy, nanotechnology
Researchers have significantly accelerated ion movement using nanotechnology, potentially improving technologies from battery charging to biosensing.
This breakthrough at Washington State University and Lawrence Berkeley National Laboratory involves creating a nanochannel lined with molecules that attract ions, allowing them to move over ten times faster than before. This development could revolutionize energy storage and help detect environmental pollutants or neurological activities.

Stem Cells Grown in Space Turn Out to Have a Surprise Advantage
Posted by Genevieve Klien in category: biotech/medical
Stem cells are special in the way they can keep on replicating, and turn themselves into many other types of cell. Now scientists have discovered how their superpowers get a remarkable boost when they’re grown in space.
The microgravity environment increases some of the regenerative capacities of stem cells even further, researchers from the Mayo Clinic in Florida have found, based on experiments carried out on the International Space Station (ISS).
As stem cells play such a crucial role in the body’s repair process, with their ability to quickly replicate and differentiate, these findings could help in the study of disease prevention and treatment.

Improving cancer therapy using sonoenhancement with acoustic cluster therapy
Posted by Omuterema Akhahenda in category: biotech/medical
Acoustic Cluster Therapy (ACT®)consists of clusters of gas-filled microbubbles and oil microdroplets.
During the last decade ACT® has been evaluated preclinically in various cancer models and combined with different drugs. It was first observed that ACT was able to increase the fluorescence from a tumor when sonoenhancement was combined with fluorescent macromolecules (Wamel 2016, Figure 1). Here it was found that already one minute after sonoenhancement, fluorescence had increased in the tumor compared to a non-treated control, followed by a fluorescence uptake that remained for several hours. Subsequently, ACT has been tested therapeutically in preclinical models of prostate cancer (Wamel 2016), pancreatic cancer (Kotopoulis 2016, Ng 2022), colon cancer (Bush 2019) and breast cancer (Bush 2020). The combination of ACT and drug was significantly better than the drug alone in all these studies, with quite large numbers of complete remissions. Combining ACT with the drug nab-paclitaxel for treatment of prostate cancer resulted in complete tumor remission in all tested animals. This shows that ACT provides sonoenhancement across very different cancer types and with different types of drugs, which increases the likelihood of seeing effects also in clinical trials as the tumor models collectively represents a variety of cancer biology.
Side effects and toxicity have also been tested in various small animal models during the last decade. During treatment, no bleeding or macroscopic damage was observed, and pathological evaluation has not identified microscopic damages. ACT was extensively tested for systemic toxicities, including studies in rats and dogs where ultrasound to the heart and liver was used to activate the ACT bubbles, and no significant adverse effects have been detected.
