A global team of researchers has developed a new strategy for fast and reliable antibody tests, which can quantify the immune response induced by vaccination and reveal the timeline and stage of pathogen infection.
Led by Professor Martin Hegner, Principal Investigator in CRANN and Trinity College Dublin's School of Physics, the team's one-step quantitative antibody tests are conducted using (blood) serum and are on a par with the gold-standard, enzyme-linked immunosorbent assay (ELISA) technique.
Laparoscopic surgery, a less invasive alternative to conventional open surgery, involves inserting thin tubes with a tiny camera and surgical instruments into the abdomen. To visualize specific surgical targets, ultrasound imaging is used in conjunction with the surgery. However, ultrasound images are viewed on a separate screen, requiring the surgeon to mentally combine the camera and ultrasound data.
Researchers at Baylor College of Medicine found that while most individuals responded to respiratory syncytial virus (RSV) natural reinfection with a typical sustained antibody response associated with protection, a few individuals surprisingly responded atypically, not being able to sustain the antibody response, which declined to levels that made the individuals susceptible to RSV reinfection.
Researchers from Nanyang Technological University, Singapore (NTU Singapore), Singapore University of Technology and Design (SUTD) and Khoo Teck Puat Hospital (KTPH) have developed a new way to create "food inks" from fresh and frozen vegetables, that preserves their nutrition and flavour better than existing methods.
Food inks are usually made from pureed foods in liquid or semi-solid form, then 3D-printed by extrusion from a nozzle, and assembled layer by layer.
Tsukuba, Japan - Although exercise is known to enhance cognitive function and improve mental health, the neurological mechanisms of this link are unknown. Now, researchers from Japan have found evidence of the missing link between aerobic fitness and cognitive function.
In a study published in Medicine & Science in Sports & Exercise, researchers from the University of Tsukuba revealed that spontaneous eye blink rate (sEBR), which reflects activity of the dopamine system, could be used to understand the connection between cognitive function and aerobic fitness.
The COVID-19 pandemic has had a profound effect on higher education -- shifting classes online, canceling events, and putting financial strain on institutions.
Amsterdam, NL, February 3, 2021 - Patients with Parkinson's disease (PD) and healthcare professionals caring for them have expressed concerns about the COVID-19 vaccine's efficacy and safety in the specific context of PD and its symptomatic treatment. In a commentary just published in the Journal of Parkinson's Disease, a set of experts addresses these concerns from an evidence-based perspective.
WHAT:
An experimental single-dose, intranasal influenza vaccine was safe and produced a durable immune response when tested in a Phase 1 study published in the Journal of Clinical Investigation. The investigational vaccine, called Ad4-H5-VTN, is a recombinant, replicating adenovirus vaccine designed to spur antibodies to hemagglutinin, a protein found on the surface of influenza viruses that attaches to human cells.
BATON ROUGE, LOUISIANA - In patients with type 2 diabetes, big swings in blood sugar levels between doctors' visits are associated with an increased risk of heart disease.
The study, published in the journal Diabetes, Obesity & Metabolism, looked at more than 29,000 patients with type 2 diabetes over a two-year period. Patients who already had heart disease were excluded.
A study published in the journal Applied Ergonomics compared the standardised processes set out for community pharmacists to follow when dispending medication to what happens in reality. A gap was revealed and researchers also looked at the reasons for this.
BOSTON - Although abnormal blood clotting has been identified as one of the primary causes of death from COVID-19, early treatment in an intensive care unit (ICU) with therapeutic anticoagulation (anti-clotting) for adults who are critically ill with COVID-19 does not appear to improve chances of survival, and could do more harm than good by increasing the risk for major bleeding, a multicenter research group cautions.
Studies examining the effectiveness of treatments for COVID-19 often do not include the very populations hardest hit by the disease, according to a new review by University of Chicago Medicine researchers.
The findings, based on an analysis of all US COVID-19 treatment trials registered on ClinicalTrials.gov, were published Jan. 27 in the Journal of General Internal Medicine.
PITTSBURGH, Feb. 3, 2020 - In a recurring pattern of evolution, SARS-CoV-2 evades immune responses by selectively deleting small bits of its genetic sequence, according to new research from the University of Pittsburgh School of Medicine.
Like weeds sprouting from cracks in the pavement, cancer often forms in sites of tissue damage. That damage could be an infection, a physical wound, or some type of inflammation. Common examples include stomach cancer caused by H. pylori infection, Barrett's esophagus caused by acid reflux, and even smoking-induced lung cancer.
ATLANTA - FEBRUARY 3, 2021 - New study finds more than half (56.4%) of cancer survivors in the United States reported having additional underlying medical conditions associated with severe COVID-19 illness. The report appearing in JNCI: The Journal of the National Cancer Institute, suggests that prevalence of these conditions among cancer survivors is nearly 40% higher than that in the general population.
