PETA scientists come up with state-of-the-art tools to implement animal-free research

This week marks the 11th World Congress on Alternatives and Animal Use in the Life Sciences, and the thousands of scientists attending this year's virtual conference will hear from PETA scientists on matters ranging from scientific and ethical concerns regarding inflicting permanent brain damage on primates to toxicity testing in rabbits.

Airflow optimization reduces time required to remove particulate matter from the classroom

According to the WHO, about 7 million people die each year due to air pollution. Particulate matter (PM) triggers inflammatory responses in the human body, causing asthma and other respiratory and cardiovascular diseases. It is more fatal for young and growing students. The Korea Institute of Civil Engineering and Building Technology (KICT) has reduced time required to remove particulate matter from the classroom by more than 30% by optimizing the locations of supply and return diffusers for air supplied into the classroom.

SARS-CoV-2 destabilizes host RNA to improve fitness

In a study recently published in the journal Nature Communications, scientists have mapped the interactions between SARS-CoV-2 RNA and host RNA. They have observed that the virus heavily methylates its genome using the methylation machinery of the host RNA, leading to an improvement in viral fitness.

FDA approves drug-free stroke rehabilitation system to treat upper extremity motor deficits

The U.S. Food and Drug Administration today approved the MicroTransponder Vivistim Paired VNS System (Vivistim System), a first-of-its-kind, drug-free rehabilitation system intended to treat moderate to severe upper extremity motor deficits associated with chronic ischemic stroke—a stroke caused by a blockage of blood flow to the brain with long-lasting symptoms—using vagus nerve stimulation (VNS).

Study: One half of hospitalized COVID-19 patients experience persistent symptoms after one year

Most symptoms of COVID-19 in hospitalized patients are resolved within 12 months, however, around one half still experience at least one persistent symptom, a study of 1,276 patients from Wuhan, China, published in The Lancet, has found.

Post-traumatic stress symptoms in COVID-19 survivors linked with changes to the brain's connectivity

COVID-19 survivors report significantly higher symptoms of post-traumatic stress, and these symptoms are associated with changes to the brain's connectivity, according to a study coauthored by Vince Calhoun, Distinguished Professor of Psychology at Georgia State University and director of the Center for Translational Research in Neuroimaging and Data Science (TReNDS).

COVID-19 pandemic illuminates the importance of airborne transmission of respiratory viruses

SARS-CoV-2, the virus behind today's global coronavirus pandemic, spreads primarily by inhalation of virus-laden aerosols at both short and long ranges - and a comprehensive new assessment of respiratory viruses finds that many others probably do as well.

New blood test could save thousands of lives by predicting sepsis before symptoms appear

Clinicians at Portsmouth's Queen Alexandra Hospital are leading medical trials of a blood test that could help to save thousands of UK lives a year by predicting sepsis days before patients show any symptoms.

Study assesses the use of complementary and integrative healthcare by people with spinal cord injury

In a cross-sectional self-report study led by experts from five Spinal Cord Injury Model Systems Centers, a survey of people with spinal cord injury revealed that 80 percent of participants were current or previous users of complementary and integrative healthcare approaches such as multivitamins, massage, and acupuncture.

Preliminary study suggests nitric oxide may be a potential treatment for COVID-19 respiratory failure

New research led by Devang K. Sanghavi of the Mayo Clinic in Florida, USA, suggests pre-intubation use of nitric oxide for patients with COVID-19–related hypoxemic respiratory may help reduce patients' mortality. Their findings show that inhaling nitric oxide in this patient population could reduce the need for future intubation and other invasive mechanical ventilation.

Oral mucosa identified as potential target for SARS-CoV-2 infection

A recent study suggested that ACE2 receptors are expressed in oral tissues, making the oral cavity an important potential entry point of SARS-CoV-2.

Potential variant of interest in South Africa assigned to the PANGO lineage C.1.2

Continual genomic surveillance of the SARS-CoV-2 strains in South Africa has revealed an increase in the number of sequences belonging to C.1 lineage during the third wave (May 2021) of SARS-CoV-2 infections. This observation was unexpected because C.1 was last reported in January 2021.

The influence of COVID-19 on platelet activation and aggregation

In a paper recently uploaded to the bioRxiv* preprint server, humanized ACE2 mice are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and platelets are subsequently isolated from the blood for quantitative proteomic analysis.
