Osaka, Japan - Chemotherapy has a damaging effect on hematopoietic stem and progenitor cells (HSPCs) in bone marrow. However, once chemotherapy ends, HSPCs regenerate, a process that has remained unknown—until now. In a new study, researchers from Osaka University have identified the molecular mechanism by which HSPCs recover after injury.
More Antarctic meltwater is surfacing than was previously known, modifying the climate, preventing sea ice from forming and boosting marine productivity- according to new research from the University of East Anglia (UEA).
For the first time, researchers have been able to obtain full-depth glacial meltwater observations in winter, using instruments attached to the heads of seals living near the Pine Island Glacier, in the remote Amundsen Sea in the west of Antarctica.
Background: Although caregivers of patients with eating disorders usually experience a heavy caregiving burden, the effects of social support on caregivers of patients with eating disorders are unknown. This study aimed to investigate how social support for mothers who are caregivers of patients with an eating disorder improves the mothers' mental status and, consequently, the symptoms and status of the patients.
Autophagy is an intracellular degradation process of cytosolic materials and damaged organelles. Researchers at Ubiquitin Project of TMIMS have been studying the molecular mechanism of mitophagy, the selective autophagy process to eliminate damaged mitochondria. PINK1 (a serine/threonine kinase) and Parkin (a ubiquitin ligating enzyme: E3) work together to ubiquitylate the outer membrane proteins of damaged mitochondria, then ubiquitin chains are recognized as signals for autophagy degradation.
Frequently occurring chronic skin inflammation like in atopic dermatitis (AD or neurodermatitis) and psoriasis have different causes such as genetic predisposition, stress or allergens. These frequently occurring skin diseases are mostly attributed by biomedical scientists to a disturbed immune system, although the noticeable thickening and flaking of the epidermis, which is the outermost layer of skin, also indicates a disruption of the epithelial cells.
Two thirds of children use more than one screen at the same time after school, in the evenings and at weekends as part of increasingly sedentary lifestyles, according to new research at the University of Leicester.
An NIHR study of more than 800 adolescent girls between the ages of 11 and 14 identified worrying trends between screen use and lower physical activity - including higher BMI - as well as less sleep.
Can Switzerland, as planned, cut its CO2 emissions to zero by 2050? In a study, researchers at the Paul Scherrer Institute PSI have investigated what measures would be necessary to achieve this reduction and how much it might cost per person.
PHILADELPHIA - Intellectual disability puts individuals at higher risk of dying earlier in life than the general population, for a variety of medical and institutional reasons. A new study from Jefferson Health examined how the COVID-19 pandemic has affected this group, which makes up 1-3% of the US population.
Patients can spend up to six years waiting for a kidney transplant. Even when they do receive a transplant, up to 20 percent of patients will experience rejection. Transplant rejection occurs when a recipient's immune cells recognize the newly received kidney as a foreign organ and refuse to accept the donor's antigens. Current methods for testing for kidney rejection include invasive biopsy procedures, causing patients to stay in the hospital for multiple days.
A group of researchers, spanning six universities and three continents, are sounding the alarm on a topic not often discussed in the context of conservation--misinformation.
In a recent study published in FACETS, the team, including Dr. Adam Ford, Canada Research Chair in Wildlife Restoration Ecology, and Dr. Clayton Lamb, Liber Ero Fellow, both based in the Irving K. Barber Faculty of Science, explain how the actions of some scientists, advocacy groups and the public are eroding efforts to conserve biodiversity.
New research reveals an essential step in scientists' quest to create targeted, more eco-friendly fungicides that protect food crops.
Scientists have known for decades that biological cells manufacture tiny, round structures called extracellular vesicles. However, their pivotal roles in communication between invading microorganisms and their hosts were recognized only recently.
?Micro-Doppler radars could soon be used in clinical settings to predict injury risk and track recovery progress, according to Penn State researchers.?
A new path toward sending and receiving information with single photons of light has been discovered by an international team of researchers led by the University of Michigan.
Their experiment demonstrated the possibility of using an effect known as nonlinearity to modify and detect extremely weak light signals, taking advantage of distinct changes to a quantum system to advance next generation computing.
In less than a second, a small sensor used in brain chemistry research can detect the key molecules that provide the genetic instructions for life, RNA and DNA, a new study from American University shows.
The AU researchers believe the sensor is a useful tool for scientists engaged in clinical research to measure DNA metabolism, and that the sensor could be a quick way for lab clinicians to distinguish 'healthy' from 'sick' samples and determine if a pathogen is fungal, bacterial, or viral, before conducting further analysis.
The Pazyryk carpet is the world's oldest example of a knotted-pile carpet and is kept at the State Hermitage Museum in St. Petersburg, Russia. The carpet, which was made out of new wool at around 400 BC, is one of the most exciting examples of central Asian craftsmanship from the Iron Age.
