Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.
A new study finds that a medication commonly prescribed to prevent and combat symptoms of acute mountain sickness does not reduce exercise performance at high altitudes. This may be especially important for military personnel and first responders not accustomed to working above sea level.
Parkinson's patients' motor and non-motor symptoms were improved with a weekly exercise regimen that included physical and cognitive tasks, according to new research presented today (18 December) at The Physiological Society early career conference, Future Physiology 2019: Translating Cellular Mechanisms into Lifelong Health Strategies.
Medicines such as insulin for diabetes and clotting factors for hemophilia are hard to synthesize in the lab. Such drugs are based on therapeutic proteins, so scientists have engineered bacteria into tiny protein-making factories.
Researchers have identified a genetic signature with prognostic value for certain kinds of breast cancer. The discovery also contributes to a better understanding of the molecular mechanisms of pathological angiogenesis, the aberrant proliferation of blood vessels that occurs during cancer and other diseases.
Pathogens can use a range of toxins to damage their host organism. Bacteria, such as those responsible for causing the deadly Plague, use a special injection mechanism to deliver their poisonous contents into the host cell.
From arthritis and heart failure to diabetes and menopause, many conditions are associated with muscle weakness and increased fat deposits.
Axons are the long thread-like extensions of neurons that send electrical signals to other brain cells. Thanks to axonal connectivity, our brains and bodies can do all necessary tasks.
Air pollution is injurious to our lungs and our blood vessels, according to many previous studies. However, a new study published on December 16, 2019, in the Journal of Physiology, says that the human heart responds to air pollution in more or less the same way as that of sea-living creatures.
Toxic environmental agents, to which anyone is involuntarily exposed, represent non-negligible risk for human health and, therefore, environmental contamination has become a theme of primary importance worldwide.
Air pollution is associated with detrimental effects on human health, including increased risk of heart disease and stroke.
"The human immune system makes my head explode," Pulitzer Prize-winning journalist Matt Richtel recently told a University of Alabama at Birmingham freshman seminar on immunology. "This is by far the hardest subject I have ever had to explore."
Using new high-resolution imaging techniques, MDC researchers and colleagues have tracked titin, the body's largest protein, in real time throughout its entire lifecycle. The method and results could provide new insight into muscle development as well as treating damaged muscles and heart disease.
Weight loss mandates healthy eating and control of impulses when it comes to eating fat rich and processed foods. The actual story is quite different, as most persons on a diet have found out the hard way. The smell of food and even thoughts have given rise to binge eating, indulging in excessive food intake that has led to obesity and weight gain.
A review of more than 130 studies explains how sleep helps people learn new information and plays an important role in storing learned content for future use. The review is published in the January 2020 issue of Physiology.
High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a potentially fatal disease caused by obstruction of blood flow in the lungs.
You're on a diet, but the aroma of popcorn in the movie theater lobby triggers a seemingly irresistible craving.
As technology advances in the things we use every day, it's generally accepted they also become safer. But according to one UBC engineer, that may not be true for a large portion of the population.
SleepCogni has announced it will trial its unique insomnia treatment, following a £575k interim fund raising round, which includes existing shareholders and a new Innovate UK biomedical catalyst award, bringing its total funding to £1.7m to date.
Normally, bird flu viruses do not spread easily from person to person. But if this does happen, it could trigger a pandemic. Researchers from the MDC and RKI have now explained in the journal Nature Communications what makes the leap from animals to humans less likely.
A study by researchers in the United States and India has shown that probiotic yeasts derived from food are able to reduce the virulence of, and even prevent infections by, several types of fungi that are responsible for life-threatening infections in hospitalized and immune-compromised individuals, including the multi-drug resistant Candida auris, which was recently listed as an urgent threat by the U.S. Centers for Disease Control in its 2019 Antibiotic Resistance Threats report.
