Black children have significantly higher rates of shellfish and fish allergies than White children, in addition to having higher odds of wheat allergy, suggesting that race may play an important role in how children are affected by food allergies, researchers at Ann & Robert H. Lurie Children's Hospital of Chicago, Rush University Medical Center and two other hospitals have found.
Results of the study were published in the February issue of the Journal of Allergy and Clinical Immunology: In Practice.
The COVID-19 pandemic has affected people's behavior everywhere. Fear, apprehensiveness, sadness, anxiety, and other troublesome feelings have become part of the daily lives of many families since the first cases of the disease were officially recorded early last year.
For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings on tinted eyeglasses reflect, or "block out," harmful blue light and ultraviolet rays.
But until now, no optical coating had ever been developed that could simultaneously reflect and transmit the same wavelength, or color.
CLEVELAND--Researchers at Case Western Reserve University, using artificial intelligence (AI) to analyze simple tissue scans, say they have discovered biomarkers that could tell doctors which lung cancer patients might actually get worse from immunotherapy.
Until recently, researchers and oncologists had placed these lung cancer patients into two broad categories: those who would benefit from immunotherapy, and those who likely would not.
Cancer is a significant cause of death worldwide and many efforts have been devoted to the development of methods for early detection. Telomerase are considered as a tumor biomarker for early diagnosis because the telomerase of more than 80% immortalized cells are reactivated and provides the sustained proliferative capacity of these cells, but the telomerase activity are not detectable in normal somatic cells. Telomerase is a ribonucleoprotein complex that is thought to add telomeric repeats onto the ends of chromosomes during the replicative phase (S phase) of the cell cycle.
Gun violence among children is lower in states with more gun laws, according to a Rutgers-led study.
The study, published in the Journal of Youth and Adolescence, examined youth gun and weapon carrying data from 2005 and 2017 across several states. Researchers found the rates of youths carrying guns were higher in states with less gun laws and lower in states with more gun laws. According to researchers, this phenomenon could be associated with large urban areas and more significant safety concerns within these areas.
COLUMBUS, Ohio - Considering the greater good by social distancing during a pandemic turns out to have an attractive personal benefit: A new study has found that staying away from others also reduces an individual person's chances of contracting COVID-19.
Researchers presented study participants with virtual behavior scenarios of various public settings - a grocery store, a crowded beach, a crosswalk - and asked them to place themselves or fictional people in those contexts based on their social distancing preferences.
Scientists like the John A. Moran Eye Center's Paul S. Bernstein, MD, PhD, know a special class of lipids, or fatty acids, found in the retina of the eye and in just a few other parts of the body play an important role in maintaining vision.
In nuclear physics so-called magic number are such nuclear proton and/or neutron numbers, for which the nucleus is more stable compared to neighboring isotopes on the nuclear chart. Researchers in both experimental and theoretical nuclear physics from University of Jyväskylä, Finland, took part of international research team, which studied the nuclear charge radii of potassium isotopes. Isotopes were studied by using the collinear resonance ionization spectroscopy technique.
Lead halide perovskites, with high refractive index and excellent optoelectronic property, have been used in both constructing high-quality optical resonators/lasers and fabricating high-efficiency light-emitting devices for advanced displays. Lenticular printing provides an illusion of depth and shows varying images upon view angles, which is considered as a promising approach towards future stereoscopic displays. To realize lenticular-printing-based display, it is required to modulate the outcoupling direction of emission light rather than that of incident light.
Researchers from the University of Ottawa have discovered that plants may be able to control the genetics of their intimate root symbionts - the organism with which they live in symbiosis - thereby providing a better understanding of their growth.
In addition to having a significant impact on all terrestrial ecosystems, their discovery may lead to improved eco-friendly agricultural applications.
LA JOLLA, CA--As the opioid epidemic raged on with an even greater force during COVID-19, the Scripps Research laboratory of chemist Kim Janda, PhD, has been working on new therapeutic interventions that may be able to prevent the bulk of deaths from opioid overdose.
Janda and his team have developed experimental vaccines that have shown in rodents to blunt the deadly effects of fentanyl--which has been driving the boom in opioid deaths--as well as its even more fatal cousin, carfentanil, a growing source of overdoses and a chemical terrorist threat.
Army scientists evaluated three nonhuman primate species as potential models of SARS-CoV-2 airborne infection, according to results published online this week in PLOS ONE. Their work demonstrates that any of these species may be useful for testing vaccines and therapies in response to the COVID-19 pandemic, which has resulted in over 104 million cases and more than 2 million deaths worldwide in the past year.
Politicians around the world must be held to account for mishandling the covid-19 pandemic, argues a senior editor at The BMJ today.
Executive editor, Dr Kamran Abbasi, argues that at the very least, covid-19 might be classified as 'social murder' that requires redress.
Today 'social murder' may describe a lack of political attention to the conditions in which people are born, grow, live, work and age that exacerbate the pandemic.
A new study further highlighting a potential physiological cause of clinical depression could guide future treatment options for this serious mental health disorder. Published in Frontiers in Psychiatry, researchers show differences between the cellular composition of the brain in depressed adults who died by suicide and non-psychiatric individuals who died suddenly by other means.
