Anti-androgen drugs may help disarm coronavirus spike protein, stop progression of COVID-19

Hormone drugs that reduce androgen levels may help disarm the coronavirus spike protein used to infect cells and stop the progression of severe COVID-19 disease, suggests a new preclinical study from researchers in the Abramson Cancer Center at the University of Pennsylvania and published online in Cell Press's iScience.

Computational analysis helps identify hematological malignancies that elude the human eye

Myelodysplastic syndrome (MDS) is a disease of the stem cells in the bone marrow, which disturbs the maturing and differentiation of blood cells. Annually, some 200 Finns are diagnosed with MDS, which can develop into acute leukemia. Globally, the incidence of MDS is 4 cases per 100,000 person years.

Study reveals the incidence of structural abnormalities in the developing brain

A large study of brain MRI scans from 11,679 nine- and ten-year-old children reviewed by UC San Francisco neuroradiologists identified potentially life-threatening conditions in 1 in 500 children, and more minor but possibly clinically significant brain abnormalities in 1 out of 25 children.

Inherited behaviors, traits that appear during adolescence may be related to adult cannabis use

While some youth experiment with marijuana but don't go on to long-term use, others develop a problematic pot habit that continues into adulthood.

Study finds two drugs capable of slowing bone marrow cancer progression

Primary myelofibrosis (PMF), a relatively rare but painful type of bone marrow cancer, disrupts the body's normal production of blood cells by causing extensive scarring in the bone marrow.

Can SARS-CoV-2 still be transmissible once symptoms have subsided?

Researchers based at the University of Missouri, in partnership with U.S. government science facilities in Maryland, have reported that individuals severely infected with SARS-CoV-2 may be able to continue shedding infectious viral RNA for over three weeks after the symptomatic infection has passed.

SARS-CoV-2 variants develop resistance against type I interferons

A study conducted at the University of Colorado and National Institutes of Health, USA, has revealed that the resistance developed by newly emerging variants of SARS-CoV-2 against host interferon responses could serve as a potential driving force for viral evolution.

Prediction of antibody responses in recovered COVID-19 patients remains unclear

It is crucial to gain a better understanding of how an antibody response is developed against SARS-CoV-2, and how long it lasts. This will determine the antibody titers and duration that protect against reinfection by the virus. A new preprint on the medRxiv* server shows this to be still a distant goal.

Male fertility and androgen production may be impacted by COVID-19

An interesting new study has appeared online in the journal Hormones that discusses the effects of COVID-19 on the male and female gonads.

NYSCF is developing new stem cell therapy to treat age-related macular degeneration

The New York Stem Cell Foundation (NYSCF) today announced that they are developing a stem cell therapy to treat patients suffering from age-related macular degeneration (AMD).

What are the chief predictors of SARS-CoV-2 infection in children?

A new study seeks to explore the factors associated with the diagnosis in children. The ability to rapidly diagnose COVID-19 in this age group is essential not only for monitoring progressive disease in individual children, but to avert further transmission chains.

Could nanoparticle vaccines offer broad protection against sarbecoviruses?

To understand the ability of SARS-CoV-2 vaccine-elicited antibodies to neutralize and protect against emerging variants (that are pathogenic) and other sarbecoviruses, a large team of researchers studied immunity by receptor-binding domain nanoparticle vaccines. They showed that a clinical-stage multivalent SARS-CoV-2 receptor-binding domain nanoparticle vaccine (SARS-CoV-2 RBD-NP) protected mice from the SARS-CoV-2-induced disease.

'Hunger Hormone' may play key role in impulsive choices and behaviors

Higher levels of the stomach-derived hormone ghrelin, which stimulates appetite, predict a greater preference for smaller immediate monetary rewards over larger delayed financial rewards, a new study finds. The study results will be presented at ENDO 2021, the Endocrine Society's annual meeting.

Researchers develop tools to detect chemical signals between the brain and immune system

If it seems like your stomach has a mind of its own, you're not wrong. University of Cincinnati assistant professor Ashley Ross says your body is full of neurons that regulate digestion, inflammation and a host of other biological processes.
