Cutaneous reactions after mRNA COVID-19 vaccines

BOSTON - Skin problems such as itchiness, rashes, hives and swelling can occur in some individuals after receiving a COVID-19 vaccine, but it's not clear how common these reactions are or how frequently they recur with a subsequent vaccination. Research by led by allergists at Massachusetts General Hospital (MGH) now provides encouraging indications that the reactions are rare, and that even when they do occur with an initial COVID-19 vaccination, they seldom recur after receiving a second vaccine dose. For the study, which is published in JAMA Dermatology, a team led by Kimberly G. Blumenthal, MD, MSc, co-director of the Clinical Epidemiology Program within MGH's ...

Migratory birds carry most seeds in the wrong direction to help plants cope with climate change, new research shows. The study, published in Nature, reveals that the vast majority of plants from European woodlands are dispersed by birds migrating to warmer latitudes in the south, while far fewer are dispersed by birds migrating north. As a consequence of global warming, the optimal climatic conditions of species are moving towards cooler latitudes, forcing the redistribution of life on Earth. Mobility allows many animals to reach new areas with a suitable climate. However, movement of plant species depends on the dispersal of their seeds at long ...

CHAPEL HILL, NC--Researchers at the University of North Carolina at Chapel Hill and the UNC Lineberger Comprehensive Cancer Center have uncovered a new mechanism that activates specific genes, leading to the development of cancers. They showed that a mutation that fuses two unrelated genes can promote a process similar to that observed when oil and water are mixed but do not blend together. The process, called liquid-liquid phase separation, occurs inside a cell's nucleus and enables the formation of compartments with various physical properties that can promote cancers such as acute leukemias. Their findings will be published online June 23, 2021, in Nature. "Phase separation and its role in cancer has been a missing puzzle piece in understanding this disease," said UNC Lineberger's ...

A joint research team led by Prof. LIU Zhongmin, Prof. WEI Yingxu, and Prof. XU Shutao from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) revealed the mechanism underlying the formation of the first carbon-carbon (C-C) bond formation during the methanol-to-olefins (MTO) process. This study was published in Chem on June 23. Prof. ZHENG Anmin's group from Innovation Academy for Precision Measurement Science and Technology of CAS was also involved in the study. The first C-C bond in the MTO process is formed at the initial stage of the reaction. There is no direct method to elucidate the bond formation /reaction mechanism due to the difficulty in capturing intermediate species. "We investigated the ...

A paper published in the prestigious journal Nature Medicine on long-COVID, describes persistent symptoms six months after acute COVID-19, even in young home isolated people. The study from the Bergen COVID-19 Research Group followed infected patients during the first pandemic wave in Bergen Norway. "The main novel finding is that more than fifty per cent of young adults up to 30 years old, isolated at home, still have persistent symptoms six months after mild to moderate disease", the leader of the group, Professor Nina Langeland explains. The most common symptoms were loss of smell and/or taste, fatigue, ...

Pioneering research has shown marine ecosystems can start working again, providing important functions for humans, after being wiped out much sooner than their return to peak biodiversity. The study, led by the University of Bristol and published today in Proceedings of the Royal Society B, paves the way for greater understanding of the impact of climate change on all life forms. The international research team found plankton were able to recover and resume their core function of regulating carbon dioxide levels in the atmosphere more than twice as fast as they regained full levels of biodiversity. Senior author Daniela Schmidt, Professor ...

An accurate, non-invasive, and low-cost method of testing for COVID-19 using samples taken from the screens of mobile phones has been developed by a team led by UCL researchers at Diagnosis Biotech. The study, published in eLife and led by Dr Rodrigo Young (UCL Institute of Ophthalmology), analysed swabs from smartphone screens rather than directly from people, and found that people who tested positive by the regular nasal swabbing PCRs were also positive when samples were taken from phone screens. The new method - known as Phone Screen Testing (PoST) - detected the COVID-19 virus on the phones of 81 to 100% of contagious people with a high viral load, suggesting it is as accurate as antigen lateral flow tests. Globally active screening for COVID-19 is still a priority ...
