Nanoparticles Repair Lung Tissue Damaged From Flu or COVID-19

Confocal imaging demonstrating the dense network of capillary blood vessels in the lung that allow oxygen to move into our bloodstream. This complex vascular network can be severely disrupted upon viral infections like influenza and COVID-19, which greatly contributes to disease severity and mortality. Credit: Gan ZhaoRecent research reveals a breakthrough in lung repair, showing how delivering VEGFA via lipid nanoparticles can significantly repair damaged blood vessels, akin to plumbing repairs. This method, validated in…

Study reveals racial disparities in school enrollment during COVID-19

Change in enrollment from 2019–2020 to 2020–2021. “Raw” changes are average enrollment changes from 2019–2020 to 2020–2021 while “adjusted” changes are relative to pre-existing trends in log enrollments from 2016–2020. Elementary = grades 1–5. Credit: Proceedings of the National Academy of Sciences (2024). DOI: 10.1073/pnas.2307308120 Student enrollment in districts that provided in-person schooling in fall 2020 during the…

Headaches, Memory Problems, and Fatigue – How COVID-19 Affects the Brain

Neurological symptoms in COVID-19 patients, such as headaches and fatigue, may not be due to direct brain infection but rather the body’s immune response to the virus, with studies showing no virus in brain neurons.Neurological symptoms are apparently not a result of SARS-CoV-2 infection of the brain.Scientists still are not sure how neurological symptoms arise in COVID-19. Is it because SARS-CoV-2 infects the brain? Or are these symptoms the result of inflammation in the rest of the body? A study by Charité –…

Gut Bacteria’s Surprising Role in Combating Flu and COVID-19

Research from Georgia State University shows that gut bacteria, particularly segmented filamentous bacteria, play a crucial role in protecting mice against respiratory viruses by influencing immune cells in the lungs. This study could have profound implications for understanding and managing respiratory infections in humans.Researchers at the Center for Translational Antiviral Research within the Institute for Biomedical Sciences at Georgia State University have discovered that the makeup of gut microbiota affects mice’s…

One Simple Change May Dramatically Boost The Effect of COVID-19 Vaccines : ScienceAlert

Sometimes it's the simplest solutions that get lost in the kerfuffle of scientific progress.Since the advent of vaccines more than two centuries ago, researchers have studied all sorts of ways in which inoculation with a weakened pathogen (or parts thereof) can prepare the immune system for a full attack – exploring different dosages, vaccine agents, and forms of administration.In all that time, very few experts have investigated the question: Does it matter which arm gets vaccinated?Researchers at Oregon Health &…

How Natural Killer Cell Therapy Offers a Lifeline to COVID-19 ARDS Patients

Recent trials of the iNKT cell therapy agenT-797 have demonstrated significant improvements in survival rates for critically ill COVID-19 patients with ARDS. This innovative treatment, which bolsters the immune response and reduces inflammation, offers hope for broader applications beyond COVID-19. Credit: SciTechDaily.comInitial trial suggests invariant natural killer cell therapy improves survival.Promising trial results indicate that a new type of cell therapy could improve the prognosis of those who are critically ill…

Singapore removes personal data collected for COVID-19 contact tracing

User registration data, which was kept to enable quick rollout and registration for both systems, should a new variant emerge, has also been erased. Also: The top cloud storage services you can buy to protect your filesThe only data retained was collected via the TraceTogether system and used in relation to a May 2020 murder case. This information will be held indefinitely by the Singapore Police Force to facilitate potential legal applications, should the conviction or sentence be challenged years after the case has
