New research published in Experimental Physiology highlight the possible long term health impacts of COVID-19 on young, relatively healthy adults who were not hospitalized and who only had minor symptoms due to the virus.
Just as people keep their houses clean and clutter under control, a crew of cells in the body is in charge of clearing the waste the body generates, including dying cells. The housekeeping cells remove unwanted material by a process called phagocytosis, which literally means 'eating cells.' The housekeepers engulf and ingest the dying cells and break them down to effectively eliminate them.
Retinoblastoma starts in the retina, the thin membrane at the back of the eye. Most patients are infants or toddlers when their cancer is found. Without treatment, the cancer spreads. Thanks to chemotherapy, surgery and other treatments, 96% of patients survive.
St. Jude researchers studied how survivors fared years later at home and at school. A previous St. Jude study of 98 retinoblastoma survivors found that their early learning and life skills declined from diagnosis to age 5.
Recently published research from the University of Arizona Health Sciences shows that advanced-stage kidney cancer is more common in Hispanic Americans and Native Americans than in non-Hispanic whites, and that both Hispanic Americans and Native Americans in Arizona have an increased risk of mortality from the disease.
New research from Simon Fraser University suggests that students learning remotely become night owls but do not sleep more despite the time saved commuting, working or attending social events.
Loneliness and social isolation have been significant problems for the general population during the COVID-19 pandemic, but for cancer patients these issues were particularly acute, likely due to isolation and social distancing, according to a new UCSF study.
The study, which is the first to evaluate loneliness, anxiety, depression, fatigue and other symptoms in a single group of patients, is published in Cancer, a peer-reviewed journal of the American Cancer Society.
Researchers at North Carolina State University and the University of North Carolina Greensboro made a surprising finding while examining areas where sand flies rear their young: a new species of bacteria that is highly attractive to pregnant, or gravid, sand flies. The findings could advance the production of ecologically safe baits or traps to reduce sand fly populations.
HOUSTON - (May 6, 2021) - A Rice University laboratory has adapted its laser-induced graphene technique to make high-resolution, micron-scale patterns of the conductive material for consumer electronics and other applications.
Laser-induced graphene (LIG), introduced in 2014 by Rice chemist James Tour, involves burning away everything that isn't carbon from polymers or other materials, leaving the carbon atoms to reconfigure themselves into films of characteristic hexagonal graphene.
As the human body's largest organ, the skin is responsible for protecting against a wide range of possible infections on all fleshy surfaces, from head to toe. So how exactly does the skin organize its defenses against such an array of threats?
A new Yale study shows that the epidermis, the outermost layer of skin, is comprised of an army of immune cells that station themselves at regular intervals across the skin's vast expanse to resist infection. When necessary, the researchers found, these immune system soldiers are able to reposition themselves to protect vulnerable areas.
Early on in the COVID-19 pandemic, health officials seized on contact tracing as the most effective way to anticipate the virus's migration from the initial, densely populated hot spots and try to curb its spread. Months later, infections were nonetheless recorded in similar patterns in nearly every region of the country, both urban and rural.
SAN FRANCISCO, CA--May 6, 2021--In the brain of a person with Alzheimer's disease, neurons degenerate and die, slowly eliminating memories and cognitive skills. However, not all neurons are impacted equally. Some types of neurons in certain brain regions are more susceptible, and even among those subtypes--mysteriously--some perish and some do not.
LOS ANGELES (May 6, 2021) -- A team of researchers from UCLA, Cedars-Sinai and the Cystic Fibrosis Foundation has developed a first-of-its-kind molecular catalog of cells in healthy lungs and the lungs of people with cystic fibrosis.
The catalog, described today in the journal Nature Medicine, reveals new subtypes of cells and illustrates how the disease changes the cellular makeup of the airways. The findings could help scientists in their search for specific cell types that represent prime targets for genetic and cell therapies for cystic fibrosis.
PHILADELPHIA-- When evaluating the opioid crisis, research reveals that external factors - such as the volume of pre-filled syringes, or a default number of opioid tablets that could easily be ordered at discharge for the patient - can shift prescribing and compel emergency department (ED) physicians to administer or prescribe greater quantities of opioids.
How did people living in the Bronze Age manage their finances before money became widespread? Researchers from the Universities of Göttingen and Rome have discovered that bronze scrap found in hoards in Europe circulated as a currency. These pieces of scrap - which might include swords, axes, and jewellery broken into pieces - were used as cash in the late Bronze Age (1350-800 BC), and in fact complied with a weight system used across Europe.
Scientists from Nanjing University and University of Macau have discovered nano-scaled apoptotic bodies (ABs) as a new brain-targeting drug carrier, bringing new promise for the Parkinson's Disease as well as other brain diseases.
