A two-dose schedule could make HIV vaccines more effective

Posted by in category: biotech/medical

Several years ago, MIT researchers showed that administering a series of escalating doses of an HIV vaccine over a two-week period could help overcome a part of that challenge by generating larger quantities of neutralizing antibodies. However, a multidose vaccine regimen administered over a short time is not practical for mass vaccination campaigns.

In a new study, the researchers have now found that they can achieve a similar immune response with just two doses, given one week apart. The first dose, which is much smaller, prepares the immune system to respond more powerfully to the second, larger dose.

This was created by a company called Xenex a decade ago In San Antonio Texas, where I used to live.


JOINT BASE LANGLEY-EUSTIS, Va. (AFNS) — Standing at 5 feet 2 inches tall, U.S. Air Force Hospital Langley’s newest staff member doesn’t initially have a commanding presence; however, after five minutes, its impact has the potential to save countless lives around the world.

The 633rd Medical Group received a germ-zapping robot, nicknamed “Saul,” which harnesses the power of technology to kill off viruses — including the Ebola virus. Airmen were given a demonstration of the robots functions and capabilities from Geri Genant, the Xenex Healthcare Services implementation manager.

George Church lab spawns $75m cell therapy startup

Posted by in categories: biotech/medical, genetics

GC Therapeutics’ plug-and-play stem cell programming platform aims to reduce cell therapy development time by up to 100 times.

Cell therapies have revolutionized the treatment of certain disease areas; however, challenges in scaling these therapies…


Cell therapy startup GC Therapeutics (GCTx) has emerged from the lab of renowned geneticist George Church, securing a $65 million Series A funding round that brings the total raised by the company to a cool $75 million. The company is on a mission to enable the next generation of cell therapies through its proprietary TFome platform, which GCTx claims is the first plug-and-play induced pluripotent stem cell (iPSC) cellular programming platform.

Study shows cholesterol enhances exosome-mediated RNA drug delivery

Posted by in categories: biotech/medical, genetics

RNA interference (RNAi) technology has gradually become a cutting-edge technology for treating diseases such as genetic disorders and cancer due to its huge potential in gene expression regulation. However, the efficient delivery and safety of short interfering RNA (siRNA) remain key challenges for its clinical application.

80% of Developmental Disorders Linked to Known Recessive Genes

Posted by in categories: biotech/medical, genetics

Summary: The largest and most diverse study on recessive genetic changes in developmental disorders reveals that over 80% of cases caused by recessive variants are linked to known genes. Researchers analyzed data from nearly 30,000 families and found that a shift in focus from gene discovery to interpreting changes in known genes could double diagnosis rates.

The study highlights the importance of genetic background in diagnosis and suggests that some patients may have multiple contributing genetic factors. These findings could lead to more personalized and accurate diagnoses for families affected by developmental disorders.

Wobbling Mars: Detecting Dark Matter Through Primordial Black Holes

Posted by in category: biotech/medical

Could slight wobbles in the orbit of Mars be caused by microscopic black holes that have existed since the Big Bang? This is what a recent study published in Physical Review D hopes to address as a team of researchers from the Massachusetts Institute of Technology (MIT) and UC Santa Cruz investigated how these miniscule black holes could be comprised of dark matter, which was first hypothesized in the 1970s, resulting in miniscule wobbles in the orbit of Mars. This study holds the potential to help researchers better understand the characteristics of dark matter, which remains one of the most mysterious phenomena in the universe.

“Given decades of precision telemetry, scientists know the distance between Earth and Mars to an accuracy of about 10 centimeters,” said Dr. David Kaiser, who is a professor of physics and the Germeshausen Professor of the History of Science at MIT, and a co-author on the study. “We’re taking advantage of this highly instrumented region of space to try and look for a small effect. If we see it, that would count as a real reason to keep pursuing this delightful idea that all of dark matter consists of black holes that were spawned in less than a second after the Big Bang and have been streaming around the universe for 14 billion years.”

For the study, the researchers began with handwritten calculations produced by Tung X. Tran, who eventually became the study’s lead author and is a graduate student at Stanford University, which calculated the results if a primordial black hole passed through a human body, which he calculated would push the person approximately 20 feet.

AI-based Tongue Imaging could help enable Non-Invasive Detection of Coronary Artery Disease

Posted by in categories: biotech/medical, information science, robotics/AI

Coronary artery disease (CAD) is the most common cause of illness-based death throughout the world. According to the World Health Organization, CAD causes 17.9 million deaths per year worldwide, nearly one-third of all illness-based deaths annually.

Coronary angiography is currently the best method of confirming a CAD diagnosis, but it is expensive and invasive, poses risks to patients, and is not suitable for early diagnosis and assessing disease risk.

Seeking a safer, lower-cost and more efficient diagnostic method, a research team from Beijing University of Chinese Medicine’s School of Traditional Chinese Medicine, Beijing University of Chinese Medicine’s School of Life Science, and Hunan University of Chinese Medicine’s School of Traditional Chinese Medicine has used artificial intelligence (AI) to develop a diagnostic algorithm based on tongue imaging. Their work is published in Frontiers in Cardiovascular Medicine.

Groundbreaking Study Unveils Novel Treatment for Blocking SARS-CoV-2 Entry into Cells

Posted by in categories: bioengineering, biotech/medical, chemistry, economics, health

The SARS-CoV-2 pandemic has had an unprecedented impact on global public health and the economy. Although vaccines and antivirals have provided effective protection and treatment, the development of new small molecule-based antiviral candidates is imperative to improve clinical outcomes against SARS-CoV-2. In this study, we identified UNI418, a dual PIKfyve and PIP5K1C inhibitor, as a new chemical agent that inhibits SARS-CoV-2 entry into host cells. UNI418 inhibited the proteolytic activation of cathepsins, which is regulated by PIKfyve, resulting in the inhibition of cathepsin L-dependent proteolytic cleavage of the SARS-CoV-2 spike protein into its mature form, a critical step for viral endosomal escape. We also demonstrated that UNI418 prevented ACE2-mediated endocytosis of the virus via PIP5K1C inhibition. Our results identified PIKfyve and PIP5K1C as potential antiviral targets and UNI418 as a putative therapeutic compound against SARS-CoV-2.

Despite the ongoing threat posed by new viruses following the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which led to the coronavirus disease 2019 (COVID-19) pandemic, new antiviral drugs continue to be developed to effectively block viral entry into the human body.

Professor Kyungjae Myung and his research team in the Department of Biomedical Engineering, affiliated with the IBS Center for Genomic Integrity, has discovered UNI418, a compound that effectively prevents the penetration of the coronavirus. This compound works by regulating dielectric homeostasis, thereby inhibiting the virus’s entry into human cells.
