New Research Reveals COVID-19 Leads to Cognitive and Behavioral Problems

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

The research also found that one in 5 patients reported post-traumatic stress disorder (PTSD), with 16% presenting depressive symptoms.

The study, conducted in Italy, involved testing neurocognitive abilities and taking MRI brain scans of patients two months after experiencing COVID-19 symptoms. More than 50% of patients experienced cognitive disturbances; 16%% had problems with executive function (governing working memory, flexible thinking, and information processing), 6%… See More.


COVID-19 patients suffer from cognitive and behavioral problems two months after being discharged from hospital, a new study presented at the 7th Congress of the European Academy of Neurology (EAN) has found.

Sound-induced electric fields control the tiniest particles

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

Engineers at Duke University have devised a system for manipulating particles approaching the miniscule 2.5 nanometer diameter of DNA using sound-induced electric fields. Dubbed “acoustoelectronic nanotweezers,” the approach provides a label-free, dynamically controllable method of moving and trapping nanoparticles over a large area. The technology holds promise for applications in the fields ranging from condensed matter physics to biomedicine.

The research appears online on June 22 in Nature Communications.

Precisely controlling nanoparticles is a crucial ability for many emerging technologies. For example, separating exosomes and other tiny biological molecules from blood could lead to new types of diagnostic tests for the early detection of tumors and neurodegenerative diseases. Placing engineered nanoparticles in a specific pattern before fixing them in place can help create new types of materials with highly tunable properties.

Scientists Develop New Gene Therapy Strategy to Delay Aging and Extend Lifespan

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

😀


Cellular senescence, a state of permanent growth arrest, has emerged as a hallmark and fundamental driver of organismal aging. It is regulated by both genetic and epigenetic factors. Despite a few previously reported aging-associated genes, the identity and roles of additional genes involved in the regulation of human cellular aging remain to be elucidated. Yet, there is a lack of systematic investigation on the intervention of these genes to treat aging and aging-related diseases.

How many aging-promoting genes are there in the human genome? What are the molecular mechanisms by which these genes regulate aging? Can gene therapy alleviate individual aging? Recently, researchers from the Chinese Academy of Sciences have shed new light on the regulation of aging.

Asymmetrex Publishes the First Report of Immortal DNA Strands in Human Stem Cells

Posted by in categories: biotech/medical, life extension

BOSTON (PRWEB) November 18, 2020

What does it mean for multiplying cells in the body to be immortal? The cell DNA is being replicated over and over again while being divided equally between new cells produced by cell divisions. All the new cell components produced by the DNA code are mixing with the old cell components and being divided between the new cells. So, every cell is a new cell. There is nothing really immortal about any of them. Right?

Not quite. Stem cells responsible for renewing other mature body cells are different. For a long time, tissue cell scientists had a somewhat nebulous idea that stem cells had a special longevity in organs and tissues – that they were immortal cells, lasting for as long as the human lifespan. However, no one had a molecular concept for this idea of stem cell immortality until John Cairns, a pioneer of DNA replication, started thinking about DNA mutations and cancer in the 1970’s.

Nip, Tuck, CRISPR: Gene Editing Could Give Plastic Surgery a Lift

Posted by in categories: bioengineering, biotech/medical

Circa 2018


CRISPR will realize its potential in plastic and reconstructive surgery only if plastic surgeons gain familiarity with this disruptive technology and become active contributors and leaders in applying CRISPR to their respective areas of expertise.

Self-Propelling Targeted Magneto-Nanobots for Deep Tumor Penetration and pH-Responsive Intracellular Drug Delivery

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

Circa 2020


Self-propelling magnetic nanorobots capable of intrinsic-navigation in biological fluids with enhanced pharmacokinetics and deeper tissue penetration implicates promising strategy in targeted cancer therapy. Here, multi-component magnetic nanobot designed by chemically conjugating magnetic Fe3O4 nanoparticles (NPs), anti-epithelial cell adhesion molecule antibody (anti-EpCAM mAb) to multi-walled carbon nanotubes (CNT) loaded with an anticancer drug, doxorubicin hydrochloride (DOX) is reported. Autonomous propulsion of the nanobots and their external magnetic guidance is enabled by enriching Fe3O4 NPs with dual catalytic-magnetic functionality. The nanobots propel at high velocities even in complex biological fluids. In addition, the nanobots preferably release DOX in the intracellular lysosomal compartment of human colorectal carcinoma (HCT116) cells by the opening of Fe3O4 NP gate.

Circa 2017 using this can lead to near Ironman or foglet bodies with the ability to self heal the human body. It could be used on smartphones to heal people not needing a doctor in the future. This also would allow for the biological singularity to happen.


This device shoots new genetic code into cells to make them change their purpose. Researchers say the chip could someday be used to treat injuries in humans. But they’ve got a long, long way to go.

Overcoming the Limitations of CRISPR Gene Editing with RNA Editing

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

A once forgotten technology, RNA editing has been gaining traction as a treatment for genetic conditions given its key advantages over CRISPR gene editing.

Since CRISPR-Cas9 gene editing was first reported in 2012, its promise of making gene editing faster, cheaper, and easier than ever before led to an explosion in the number of publications referring to this gene editing technology.

An increasing number of research labs and companies are aiming to translate CRISPR gene editing into therapies for genetic diseases. However, further research has unveiled that there are more limitations to using CRISPR-Cas9 to cure diseases than initially expected. For example, the technology has been reported to introduce off-target changes to the DNA, raising concerns about its safety.

Cleveland Clinic Trial to Test Gene Therapy as Treatment of Sickle Cell Disease

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

Novel study designed to correct genetic abnormalities of red blood cells.


Cleveland Clinic researchers are enrolling patients in a clinical trial that aims to work toward a cure for sickle cell disease, by changing the patient’s genetics. Sickle cell disease, a genetic blood disorder, is a painful and debilitating condition for which there are few approved therapies.

The multicenter study will evaluate the safety and effectiveness of a single dose of EDIT-301, an experimental one-time gene editing cell therapy that modifies a patient’s own blood-forming stem cells to correct the mutation responsible for sickle cell disease.
