Dragging your feet? Lack of sleep affects your walk, new study finds (Physiology)

Periodically catching up on sleep can improve gait control for the chronically sleep-deprived. Good sleep can be hard to come by. But a new study finds that if you can make up for lost sleep, even for just a few weekend hours, the extra zzz’s could help reduce fatigue-induced clumsiness, at least in how you … Continue reading Dragging your feet?

Researchers Discovered A Type of Blood Vessel Cell in Muscles That Multiplies Rapidly Upon Exercise (Physiology)

ETH Zurich Professor Katrien De Bock and her team have discovered a certain type of blood vessel cell in muscles that multiplies rapidly upon exercise, thereby forming new blood vessels. Researchers can use this to find novel therapies for vascular disorders of the muscle. “In industrialised countries, the leading cause of surgeons having to amputate … Continue reading Researchers Discovered A Type of Blood Vessel Cell in Muscles That Multiplies Rapidly Upon Exercise (Physiology)

Study Identifies Molecule That Stimulates Muscle-Building (Physiology)

In a randomized control study of 10 healthy young men, researchers compared how consuming the single amino acid leucine or its two-molecule equivalent, dileucine, influenced muscle-building and breakdown. They found that dileucine boosts the metabolic processes that drive muscle growth 42% more than free leucine does. They report their findings in the Journal of Applied … Continue reading Study Identifies Molecule That Stimulates Muscle-Building (Physiology)

Fight-or-flight Response Is Altered in Healthy Young People Who Had COVID-19 (Physiology)

New research published in the Journal of Physiology found that otherwise healthy young people diagnosed with COVID-19, regardless of their symptom severity, have problems with their nervous system when compared with healthy control subjects. Specifically, the system that oversees the fight-or-flight response, the sympathetic nervous system, seems to be abnormal (overactive in some instances and underactive in others) … Continue reading Fight-or-flight Response Is Altered in Healthy Young People Who Had COVID-19 (Physiology)

Exercise Improves Health Through Changes On DNA (Physiology)

Six weeks of physical exercise led to changes in the epigenetic information of skeletal muscle cells in young men. These changes took place in areas of the genome that have been linked to disease. Scientists at the University of Copenhagen say their research shows, for the first time, how exercise remodels DNA in skeletal muscle, … Continue reading Exercise Improves Health Through Changes On DNA (Physiology)

Daily Practice Of Three-step Breathing Exercise Associated With A Lower Percentage of COVID-19 (Physiology)

Apurvakumar Pandya and colleagues in their recent paper, assess the prevalence of Covid-19 infection among people practicing threestep rhythmic breathing (3SRB) exercise and those who were not practising. Their study indicated that the prevalence of Covid-19 is lower among people practicing 3SRB compared to those who are not practicing 3SRB. Their study recently appeared in … Continue reading Daily Practice Of Three-step Breathing Exercise Associated With A Lower Percentage of COVID-19 (Physiology)

Plant Physiology: A Tale Of Three Proteins (Botany)

LMU biologists have shown that ‘supervisor’ and ‘motivator’ proteins are required to enable a third factor to perform its function in photosynthesis. Plants, algae and cyanobacteria need only three ingredients for the synthesis of sugars via the process of photosynthesis – carbon dioxide, water and sunlight. However, the operation is far more complicated than this … Continue reading Plant Physiology: A Tale Of Three Proteins (Botany)

How Childhood Exercise Could Maintain And Promote Cognitive Function in Later Life? (Physiology)

Illuminating changes in brain networks and cortical structure A research group including Professor MATSUDA Tetsuya of Tamagawa University’s Brain Science Institute (Machida City, Tokyo; Director: SAKAGAMI Masamichi) and Assistant Professor ISHIHARA Toru from Kobe University’s Graduate School of Human Development and Environment has illuminated the changes in the brain’s neural network and cortex structure that … Continue reading How Childhood Exercise Could Maintain And Promote Cognitive Function in Later Life?

We Cannot Cheat Ageing and Death (Physiology)

New study finds fresh evidence for our inevitable death A study led by Fernando Colchero, University of Southern Denmark and Susan Alberts, Duke University, North Carolina, that included researchers from 42 institutions across 14 countries, provides new insights into the aging theory “the invariant rate of ageing hypothesis”, which states that every species has a … Continue reading We Cannot Cheat Ageing and Death (Physiology)
