Here, the authors report on the manufacturing and in vivo assessment of a bioresorbable nanostructured pH sensor. The sensor consists of a micrometer-thick porous silica membrane conformably coated layer-by-layer with a nanometer-thick multilayer stack of two polyelectrolytes labeled with a pH-insensitive fluorophore. The sensor fluorescence changes linearly with the pH value in the range 4… Continue reading Bioresorbable Nanostructured Chemical Sensor for Monitoring of pH Level In Vivo
High-dose Vitamin B6 supplementation reduces anxiety and strengthens visual surround suppression
ObjectiveVitamins B6 and B12 are involved in metabolic processes that decrease neural excitation and increase inhibition. This double-blind study investigated the effects of supplementation for 1 month with a high-dose of B6 or B12, compared to placebo, on a range of behavioural outcome measures connected to the balance between neural inhibition and excitation.Methods478 young adults… Continue reading High-dose Vitamin B6 supplementation reduces anxiety and strengthens visual surround suppression
Are Lockdowns Effective in Managing Pandemics?
The present coronavirus crisis caused a major worldwide disruption which has not been experienced for decades. The lockdown-based crisis management was implemented by nearly all the countries, and studies confirming lockdown effectiveness can be found alongside the studies questioning it. In this work, we performed a narrative review of the works studying the above effectiveness,… Continue reading Are Lockdowns Effective in Managing Pandemics?
Immune boosting by B.1.1.529 (Omicron) depends on previous SARS-CoV-2 exposure
Importance of infection historyA long-term study of healthcare workers in the United Kingdom has allowed their history of infection and vaccination to be traced precisely. Reynolds et al. found some unexpected immune-damping effects caused by infection with a heterologous variant to the latest wave of infection by the Omicron/Pango lineage B.1.1.529. The authors found that… Continue reading Immune boosting by B.1.1.529 (Omicron) depends on previous SARS-CoV-2 exposure
The Incidence of Myocarditis and Pericarditis in Post COVID-19 Unvaccinated Patients—A Large Population-Based Study
Myocarditis and pericarditis are potential post-acute cardiac sequelae of COVID-19 infection, arising from adaptive immune responses. We aimed to study the incidence of post-acute COVID-19 myocarditis and pericarditis. Retrospective cohort study of 196,992 adults after COVID-19 infection in Clalit Health Services members in Israel between March 2020 and January 2021. Inpatient myocarditis and pericarditis diagnoses… Continue reading The Incidence of Myocarditis and Pericarditis in Post COVID-19 Unvaccinated Patients—A Large Population-Based Study
Risk of covid-19 related deaths for SARS-CoV-2 omicron (B.1.1.529) compared with delta (B.1.617.2): retrospective cohort study
Objective To assess the risk of covid-19 death after infection with omicron BA.1 compared with delta (B.1.617.2).Design Retrospective cohort study.Setting England, United Kingdom, from 1 December 2021 to 30 December 2021.Participants 1 035 149 people aged 18-100 years who tested positive for SARS-CoV-2 under the national surveillance programme and had an infection identified as omicron BA.1 or… Continue reading Risk of covid-19 related deaths for SARS-CoV-2 omicron (B.1.1.529) compared with delta (B.1.617.2): retrospective cohort study
The Problem of Home Therapy during COVID-19 Pandemic in Italy: Government Guidelines versus Freedom of Cure?
After starting in late 2019, COVID-19 spread worldwide, and Italy was one of the first Western nations to be seriously affected. At that time, both the virus and the disease were little known and there were no Evidence-Based Medicine indications for treatment. The Italian Health Ministry guidelines claimed that, unless oxygen saturation fell to <92%,… Continue reading The Problem of Home Therapy during COVID-19 Pandemic in Italy: Government Guidelines versus Freedom of Cure?
Epithelial HVEM maintains intraepithelial T cell survival and contributes to host protection
Intestinal epithelia maintain T cellsImmune surveillance of the intestinal epithelium is crucial for intestinal homeostasis and protecting against infection. However, how the intestinal epithelium helps induce immune surveilling intraepithelial T cells (IET) is unclear. Here, Seo, Takahashi, and Wang et al. used mouse knockout models to demonstrate that herpes virus entry mediator (HVEM), a TNFR… Continue reading Epithelial HVEM maintains intraepithelial T cell survival and contributes to host protection
Modifications of Behavior and Inflammation in Mice Following Transplant with Fecal Microbiota from Children with Autism
Highlights•Modifications of behavior and inflammatory factors in mice gut-brain axis.•Key role of gut microbiota during the different developmental phases of ASD.•Fecal microbiota transplant improves ASD symptoms.AbstractAutism spectrum disorder (ASD) is a neurodevelopmental disorder displaying the modification of complex human behaviors, characterized by social interaction impairments, stereotypical/repetitive activities and emotional dysregulation. In this study, fecal microbiota… Continue reading Modifications of Behavior and Inflammation in Mice Following Transplant with Fecal Microbiota from Children with Autism
