Scientists demonstrate how genetic variations cause eczema

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

New research supported by the National Institutes of Health delineates how two relatively common variations in a gene called KIF3A are responsible for an impaired skin barrier that allows increased water loss from the skin, promoting the development of atopic dermatitis, commonly known as eczema. This finding could lead to genetic tests that empower parents and physicians to take steps to potentially protect vulnerable infants from developing atopic dermatitis and additional allergic diseases.

Atopic dermatitis is an that affects up to 20% of children in developed countries. This chronic is characterized by dry, thickened and intensely itchy skin, particularly in skin folds. People with eczema are more susceptible to bacterial, viral and fungal skin infections and frequently develop additional allergic diseases such as asthma.

KIF3A is a gene that codes for a protein involved in generating signals from the outside to the inside of a cell, part of a complex sensory apparatus. Previously, scientists had identified an association between two genetic variations in KIF3A and asthma in children who also had eczema. In the new study, the researchers found that these variations, or (SNPs), changed parts of the KIF3A gene to a form that can regulate, through a process called methylation, the rate at which a gene is transcribed into the blueprint for protein production. The investigators confirmed that skin and nasal-lining cells from people with the KIF3A SNP variants had more methylation and contained fewer blueprints for the KIF3A protein than cells in which KIF3A lacked the SNPs. In addition, the researchers demonstrated that people with the SNP-created regulating sites had higher levels of from the skin.

NASA’s Ingenuity Mars Helicopter Powered Up for the First Time in Interplanetary Space

Posted by in categories: energy, health, space

Headed to the Red Planet with the Perseverance rover, the pioneering helicopter is powered up for the first time in interplanetary space as part of a systems check.

NASAs Ingenuity Mars Helicopter received a checkout and recharge of its power system on Friday, August 7, one week into its near seven-month journey to Mars with the Perseverance rover. This marks the first time the helicopter has been powered up and its batteries have been charged in the space environment.

During the eight-hour operation, the performance of the rotorcraft’s six lithium-ion batteries was analyzed as the team brought their charge level up to 35%. The project has determined a low charge state is optimal for battery health during the cruise to Mars.

Pollution linked to antibiotic resistance

Posted by in categories: biotech/medical, health

Antibiotic resistance is an increasing health problem, but new research suggests it is not only caused by the overuse of antibiotics. It’s also caused by pollution.

Using a process known as , University of Georgia scientists found a strong correlation between and heavy contamination in an environment.

Jesse C. Thomas IV, an alumnus of the College of Public Health and the Savannah River Ecology Laboratory, found commonalities in soils contaminated with heavy metals on the U.S. Department of Energy’s Savannah River Site near Aiken, South Carolina.

Scientists develop artificial intelligence system for high precision recognition of hand gestures

Posted by in categories: health, robotics/AI, wearables

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed an Artificial Intelligence (AI) system that recognizes hand gestures by combining skin-like electronics with computer vision.

The recognition of human by AI systems has been a valuable development over the last decade and has been adopted in high-precision surgical robots, health monitoring equipment and in .

AI recognition systems that were initially visual-only have been improved upon by integrating inputs from wearable sensors, an approach known as ‘data fusion’. The wearable sensors recreate the skin’s sensing ability, one of which is known as ‘somatosensory’.

Can Drinking Microfiltered Raw Immune Milk From Cows Immunized Against SARS-CoV-2 Provide Short-Term Protection Against COVID-19?

Posted by in categories: biotech/medical, health

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes severe respiratory tract infections in humans (COVID-19), has become a global health concern. Currently, several vaccine candidates against SARS-CoV-2 are in clinical trials but approval of these vaccines is likely to take a long time before they are available for public use. In a previous report, the importance of passive immunity and how immunoglobulin (Ig)G collected from recovered coronavirus patients could help in the protection against COVID-19 and boost the immune system of new patients was reported. Passive immunity by immunoglobulin transfer is a concept employed by most mammals and bovine IgG has a role to play in human therapy. IgG is one of the major components of the immunological activity found in cow’s milk and colostrum. Heterologous transfer of passive immunity associated with the consumption of bovine immune milk by humans has been investigated for decades for its immunological activity against infections. This short review focuses on passive immunity and how microfiltered raw immune milk or colostrum collected from cows vaccinated against SARS-CoV-2 could provide short-term protection against SARS-CoV-2 infection in humans and could be used as an option until a vaccine becomes commercially available.

Currently, different academic institutions and pharmaceutical companies worldwide have started programs to develop and test vaccine candidates against SARS-CoV-2 in clinical trials. An S-glycoprotein-based vaccine is a promising approach that has attracted the attention of scientists, since S-glycoprotein can be directly recognized by the host’s immune system. For the first coronavirus (SARS-CoV-1), which was identified in Guangdong province, China, in November 2002, different vaccines were developed and tested in animal models. Some of these vaccines prevented animal infection after challenge with SARS-CoV-1. Kapadia et al. showed that neutralizing antibodies against SARS-CoV-1 could be detected in sera from mice immunized with S-glycoprotein of SARS-CoV-1 (10, 11).

Putting on weight slows blood flow to the brain, increasing Alzheimer’s risk

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

COSTA MESA, Calif. – Health experts say around half of American adults are overweight or obese. While excessive body weight is linked to a number of serious health conditions, including diabetes and heart disease, a new study reveals it can also reduce blood flow to the brain. Researchers warn this can put overweight individuals at great risk for Alzheimer’s disease.

The study examines brain blood flow in 17,721 adults between 18 and 94. To do this, researchers use a brain imaging technique known as single photon emission computed tomography (SPECT).

SPECT is a technique in which doctors inject a radioactive tracer into a patient’s blood and then use a special camera to look at the flow of blood. Participants were then split into five categories: underweight, normal weight, overweight, obese, and morbidly obese — to examine blood flow in each of their brains. The brain scan data reveals lower blood flow across virtually all brain regions as body weight increases.

Bacteriophages Could Be a Potential Game Changer in the Trajectory of Coronavirus Disease (COVID-19)

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

Bacteriophage can reduce bacterial growth in the lungs, limiting fluid build-up. This could decrease the mortality of patients affected by COVID-19, according to the peer-reviewed journal PHAGE: Therapy, Applications, and Research.

“The bacterial growth rate could potentially be reduced by the aerosol application of natural bacteriophages. These prey on the main species of bacteria known to cause respiratory failure,” says Marcin Wojewodzic, PhD, University of Birmingham (U.K.). Decreasing bacterial growth would also give the body more time to produce protective antibodies against the disease-causing coronavirus.

Used correctly, phages have an advantage here of being able to very specifically target the bacteria that cause secondary infections. They would remove the problematic bacterium but leave an otherwise fragile microbiome intact.” Martha Clokie, PhD, Editor-in-Chief of PHAGE and Professor of Microbiology, University of Leicester (U.K.)

Highly sensitive dopamine detector uses 2-D materials

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

A supersensitive dopamine detector can help in the early diagnosis of several disorders that result in too much or too little dopamine, according to a group led by Penn State and including Rensselaer Polytechnic Institute and universities in China and Japan.

Dopamine is an important neurotransmitter that can be used to diagnose disorders such as Parkinson’s disease, Alzheimer’s disease and schizophrenia.

“If you can develop a very sensitive, yet simple-to-use and portable, detector that can identify a wide range of dopamine concentration, for instance in sweat, that could help in non-invasive monitoring of an individual’s health,” said Aida Ebrahimi, assistant professor of electrical engineering, Penn State, and a corresponding author on a paper published Aug. 7 in Science Advances.
