Study: Second dose of COVID-19 vaccine induces a powerful boost to the immune system

The second dose of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection, according to a study led by investigators at the Stanford University School of Medicine.

Study reveals pathological mechanism and treatment strategy of pre-engraftment syndrome

The research team led by Prof. WEI Haiming and Prof. TIAN Zhigang from Division of Life Sciences and Medicine, University of Science and Technology of China of the Chinese Academy of Sciences, collaborating with the research group led by Prof. SUN Zimin from the First Affiliated Hospital of USTC revealed the pathological mechanism of severe pre-engraftment syndrome (PES) after umbilical cord blood transplantation, not only providing a treatment strategy for patients with PES, but significantly guiding for further improvement in the curative effect of unrelated cord blood transplantation (UCBT).

Study suggests children develop short-term humoral immunity following SARS-CoV-2 infection

A single-center, cross-sectional epidemiological survey conducted in Israel has recently pointed out that antibodies induced by natural SARS-CoV-2 infection in children start declining just after 4 months of acute infection. However, their seropositivity rates are not impacted by school reopening. The study has recently been published in the journal Acta Paediatrica.

Dysbiosis in gut microbiota may cause severe secondary infection in COVID-19 patients

An interesting study led by scientists in the U.S. has recently revealed that the microbial community in the gut is directly affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and that virus-mediated gut microbiome dysbiosis may cause severe secondary infections in coronavirus disease 2019 (COVID-19) patients. The study is currently available on the bioRxiv* preprint server.

Do mRNA-based COVID-19 vaccines induce memory T cell response similar to natural infection?

A team of scientists from the United States has recently compared the epitope-specific T cell response after natural severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or vaccination in both naïve and previously infected individuals.

Occasional breastfeeding shown to improve cardiac and vascular health in babies, with long-lasting benefits

New research shows that 3-year-old toddlers had lower blood pressure when they were breastfed as babies in comparison to ones that weren’t.

Patient's case report reveals link between Bell’s palsy and Pfizer-BioNTech vaccine

The case of a patient who experienced two facial palsies – one after the first and another after the second dose of the Pfizer-BioNTech COVID-19 vaccine – strongly suggests that Bell’s palsy (facial nerve palsy of unknown cause) is linked to the Pfizer-BioNTech vaccine, doctors write in the journal BMJ Case Reports.

An assay capable of detecting SARS-CoV-2 antibodies in breast milk and other samples

In a recent study by US researchers (currently available on the medRxiv* preprint server), a specific immunoassay based on the spike glycoprotein’s receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not only well suited for the detection of antibody response after infection and vaccination but may also represent a method of choice when conducting seroepidemiological studies.

Oxygen therapy may improve hypoxia-induced B cell abnormalities in COVID-19

Researchers in the United States have demonstrated early and persistent B cell abnormalities in patients with moderate or severe coronavirus disease 2019 (COVID-19) that may be largely driven by hypoxia.

Pfizer-BioNTech and Moderna COVID-19 vaccines establish recall responses to reinfection

Researchers in the United States have conducted a study showing that the coronavirus disease 2019 (COVID-19) vaccines developed by Pfizer-BioNTech and Moderna generate a coordinated adaptive immune response that is capable of eliciting recall responses to future infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Sophisticated stem cell model reveals potential route of SARS-CoV-2 entry into the brain

Researchers at University of California San Diego School of Medicine and Rady Children's Institute for Genomic Medicine have produced a stem cell model that demonstrates a potential route of entry of SARS-CoV-2, the virus that causes COVID-19, into the human brain.

Excess caffeine intake may be linked to increased risk of osteoporosis

University of South Australia researchers have a bone to pick when it comes to drinking too much coffee as new research finds that excess caffeine may be linked to an increased risk of osteoporosis.

Researchers identify novel disorder resulting from a mutation in AIOLOS protein

Primary immunodeficiencies, such as severe combined immunodeficiency disease (SCID), occur when the immune system does not work properly, leading to increased susceptibility to various infections, autoimmunity, and cancers.

Disruption in blood clotting and the first line immune system could contribute to psychosis

A scientific review has found evidence that a disruption in blood clotting and the first line immune system could be contributing factors in the development of psychosis.

RUDN University biologists discover the way how macrophages respond to inflammation

RUDN University biologists discovered the way how macrophages (the cells of the "first line" immune response) respond to inflammation and identified how the immune response depends on their origin.

Taking "z-drugs" with opioids increases risk of death

A new study by Vanderbilt University Medical Center researchers of more the 400,000 Medicare patients taking medications for insomnia found that the risk of death is increased when either benzodiazepines or "z-drugs" are taken with opioids.

MIT engineers create new diagnostic nanoparticle that can pinpoint tumor location

Most of the tests that doctors use to diagnose cancer -- such as mammography, colonoscopy, and CT scans -- are based on imaging. More recently, researchers have also developed molecular diagnostics that can detect specific cancer-associated molecules that circulate in bodily fluids like blood or urine.
