SARS-CoV-2 pandemic underscores importance of understanding evolution of RNA genomes

The current COVID-19 (coronavirus disease 2019) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), underscores the importance of understanding the evolution of ribonucleic acid (RNA) genomes.

Field of mathematics reveals a potential gene that causes acute lymphoblastic leukemia

Using a widely known field of mathematics designed mainly to study how digital and other forms of information are measured, stored and shared, scientists at Johns Hopkins Medicine and Johns Hopkins Kimmel Cancer Center say they have uncovered a likely key genetic culprit in the development of acute lymphoblastic leukemia (ALL).

Characterization of lab-produced neutralizing antibodies targeting SARS-CoV-2

A new study led by Hans-Martin Jäck of the Friedrich-Alexander University Erlangen-Nuremberg in Germany engineered clusters of neutralizing monoclonal antibodies using a transgenic mouse model. A unique characteristic for the antibodies was the different ways it bound to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the overall reduction in the viral spread for human ACE2.

Blood-brain barrier and its effect on the immune system play a role in schizophrenia

Like a stern bodyguard for the central nervous sytem, the blood-brain barrier keeps out anything that could lead to disease and dangerous inflammation--at least when all is functioning normally.

Chaperone protein imbalance can play key role in initiating toxic tau buildup in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

Two extremes of female sexual behavior may be controlled by the same brain region

In many species, including humans and mice, the fluctuating levels of the hormones progesterone and estrogen determine whether the female is fertile or not. And in the case of mice, whether she's sexually receptive or not.

Researchers reveal a potential therapeutic strategy against T-cell acute lymphoblastic leukemia

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive type of leukemia in which too many T-cell lymphoblasts, or immature white blood cells, are found in the bone marrow and blood.

Physical and mental health decline associated with more pronounced cognitive disengagement

A recent study suggests that preserving physical and mental health helps older adults experiencing cognitive impairment stave off declines in cognitive engagement.

Personal and work-related factors can increase risk for neck pain

With roughly 80% of jobs being sedentary, often requiring several hours of sitting stooped in front of a computer screen, neck pain is a growing occupational hazard. Smartphones and other devices have also caused people to bend their necks for prolonged periods. But is bad posture solely to blame?

Researchers develop new biomaterial that regrows blood vessels and bone

Scientists have developed a new biomaterial that regrows blood vessels and bone, potentially providing a single-stage approach when repairing large bone defects.

Systematic review: Exposure to endocrine-disruptors could elevate breast cancer risk

Exposure to certain endocrine-disrupting chemicals could elevate the risk of breast cancer, according to a new comprehensive systematic review of epidemiological research.

Chronic SARS-CoV-2 infections favor viral adaptation, says study

A new study offers a look at how to keep these hopes alive in the current context of highly infectious variants, which often display immune escape mutations.

Limited SARS-CoV-2 spread in childcare centers, finds study

A new study adds to the sum of evidence that children do not play a key role in the transmission of the SARS-CoV-2, the pathogen behind the current pandemic of COVID-19.

Can an immunosuppressive cancer drug promote SARS-CoV-2 entry into host cells?

A new study shows that rapamycin, an immunosuppressive drug used in some cancers, and its analogs, may have an undesirable effect on viral entry into the host cells. This finding could inform their use to treat symptomatic COVID-19.

Humoral immunity developed by DNA vaccine INO-4800 is effective against SARS-CoV-2 variants

A team of international scientists recently demonstrated that antibodies generated in response to the DNA vaccine INO-4800 can effectively neutralize some of the recently emerged variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), such as G614, 501Y.V1, and 501Y.V2.

Study examines SARS-CoV-2 seropositivity in healthy young adults and risk of reinfection

New research has been published in The Lancet Respiratory Medicine, which focuses on evaluating the effect of SARS-CoV-2 seropositivity on the possibility of developing SARS-CoV-2 infection in a young and healthy population. This study is based on the longitudinal prospective cohort study that involves the COVID-19 Health Action Response for Marines (CHARM).

Study provides the first extensive genetic and phenotype landscape of peripartum cardiomyopathy

Researchers at Penn Medicine have identified more genetic mutations that strongly predispose younger, otherwise healthy women to peripartum cardiomyopathy (PPCM), a rare condition characterized by weakness of the heart muscle that begins sometime during the final month of pregnancy through five months after delivery.

Can fingerprick blood tests help evaluate antibody response and longevity against SARS-CoV-2 post-vaccination?

To monitor antibody level duration of vaccine-induced immune responses, a team of researchers in the U.S. – at Diacarta, University of California and VA Healthcare System, and the Franciscan University of Steubenville – evaluated the feasibility of using a single drop of fingerstick blood collected with flocked swabs for quantitative antibody response evaluation after COVID-19 vaccination.

Could virosome-based nanovaccines be a promising new approach to preventing viral diseases?

A recent review in the International Journal of Biological Macromolecules provides a novel overview of 'virosome'-based nanovaccine production, its properties, and its application in viral diseases, emphasizing its importance in SARS-CoV-2 vaccine discovery.

New implantable tool images brain activity in 3D

Tools that allow neuroscientists to record and quantify functional activity within the living brain are in great demand. Traditionally, researchers have used techniques such as functional magnetic resonance imaging, but this method cannot record neural activity with high spatial resolution or in moving subjects.
