Melbourne researchers have found that liquid chalk, commonly used in gyms to improve grip, acts as an antiseptic against highly infectious human viruses, completely killing both SARS-CoV-2 (the virus that causes COVID-19) and influenza A viruses.
University of Melbourne Professor Jason Mackenzie, a laboratory head at the Peter Doherty Institute of Infection and Immunity (Doherty Institute) wanted to investigate whether liquid chalk stopped SARS-CoV-2 transmission after conversations with his daughter - an elite rock climber heading to the Tokyo Olympics.
Exercise training can help support management of overweight and obesity in adults, and can contribute to health benefits beyond "scale victories". The supplement published today in Obesity Reviews, based on the work of an expert group convened under the auspices of the European Association for the Study of Obesity (EASO), provides scientific evidence on health and wellbeing benefits of exercise training for people living with overweight and obesity.
ROCKVILLE, MD, USA - June 30, 2021 - Researchers from Sanaria® Inc. and the National Institutes of Health (NIH) are making progress in the development of highly protective malaria vaccines.
MINNEAPOLIS - Finding treatments for advanced multiple sclerosis (MS) has been difficult. But new research may help neurologists identify which drugs are best for people with the advanced form of MS called secondary progressive MS. The new study, published in the June 30, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology, found that the more potent disease-modifying drugs are more effective in reducing flare-ups in secondary progressive MS than the less potent drugs that tend to be safer to take.
Many neurodevelopmental disorders share similar symptoms, such as learning disabilities or attention deficits. A new study from MIT has uncovered a common neural mechanism for a type of cognitive impairment seen in some people with autism and schizophrenia, even though the genetic variations that produce the impairments are different for each condition.
What The Study Did: This crossover trial found that perceived breathing resistance at peak exercise is uniquely and significantly elevated when exercise stress testing (EST) is performed while wearing a mask. Performing EST with a mask yielded lower peak exercise oxygen uptake and heart rates as compared with no mask. However, each experimental condition resulted in peak exercise values that generally remained within normal limits, and no EST required termination due to clinically indicated safety concerns.
What The Study Did: Researchers in this randomized clinical trial found that a large proportion of patients who canceled visits and procedures early in the COVID-19 pandemic didn't reschedule once reopening occurred. A single message targeted directly to these patients didn't affect the return to in-person visits within a month but it resulted in a small increase in re-engagement through telemedicine and rescheduling of future visits.
Japanese and Zambian scientists have shown that environmental lead poisoning in children affects not only their own health and wellbeing, but the vitality and mental health of their mothers, as well.
Reactive oxygen species (ROS) are highly reactive chemicals which contain oxygen radicals. Hypochlorous acid, peroxides, superoxide, singlet oxygen, alpha-oxygen and hydroxyl radicals are the major examples of ROS, which are familiar to persons from many walks of life as they are used in many domestic and industrial processes. ROS are naturally produced during a variety of biochemical reactions within the cell organelles such as the endoplasmic reticulum, mitochondria and peroxisomes. ROS are also formed as a byproduct of the normal metabolism of oxygen.
HOUSTON - The University of Texas MD Anderson Cancer Center's Research Highlights provides a glimpse into recently published studies in basic, translational and clinical cancer research from MD Anderson experts. Current advances include expanded use of a targeted therapy for a new group of patients with leukemia, molecular studies yielding novel cancer therapeutic targets, insights into radiation therapy resistance and a community intervention to reduce cervical cancer rates.
Using acalabrutinib as initial treatment for chronic lymphocytic leukemia
Heart attack, medically known as myocardial infarction (MI), is a common heart condition. MI is caused by problems in blood supply to parts of the heart. In severe cases, MI could be accompanied by ruptures in the wall separating different parts of the heart, such as in the ventricular septum (a wall that separates the right ventricle that pumps deoxygenated blood to the lungs for oxygenation, from the left ventricle that pumps oxygenated blood to rest of the body). Not surprisingly, without appropriate surgical intervention, a VSR due to MI increases the chances of death.
Using an experimental model to simulate the blood-brain barrier, scientists in Sweden reported in unprecedented detail how antioxidants protect the brain from inflammation caused by neurodegenerative diseases such as Alzheimer's and Parkinson's.
In a study involving 34 women aged 50-70, researchers at the University of São Paulo (USP) in Brazil performed objective measurements of the impact on the subjects' health of the decrease in physical activity observed during the period of social distancing and isolation imposed by COVID-19. Tests conducted after the first 16 weeks of confinement pointed to a deterioration in their overall health, including loss of muscle strength and diminished aerobic capacity, as well as elevated levels of cholesterol and glycated hemoglobin, both of which are risk factors for metabolic disorders.
Individuals who contract COVID-19 even after vaccination are likely to have a lower viral load, experience a shorter infection time and have milder symptoms than people who are unvaccinated, according to research that includes data from ongoing University of Arizona Health Sciences studies.
