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.
The importance of research into the role of the immune system in the development and therapy of oncological diseases was emphasized by the Royal Swedish Academy, which recently named James Allison and Tasuku Honjo recipients of the 2018 Nobel Prize in Physiology or Medicine for launching an effective new way to attack cancer by treating the immune system rather than the tumor.
In Florida, there are more than 540,000 people living with Alzheimer's disease (AD), the most recognized form of dementia. The number of people in Florida who are age 65 and older with AD is expected to increase 41.2 percent by 2025 to a projected 720,000, highlighting the urgency of finding medical and treatment breakthroughs.
Researchers at the University of Arizona have discovered that metformin, a drug commonly used to treat type 2 diabetes, might also be used to treat heart failure with preserved ejection fraction, a condition that is predicted to affect over 8% of people ages 65 or older by the year 2020.
A novel way in which the inflammatory response to pain is regulated has been described in the open-access journal eLife.
A University of Wyoming researcher and his team have discovered that separating male and female mice, over time, changes the way they smell.
Almost all children live to see their eighteenth birthday despite a severe growth restriction, as long as they have survived their first month during infancy. This is indicated in a study by researchers at Karolinska Institutet, which is published in the journal PLOS Medicine.
A larger portion of green leafy vegetables in the diet may reduce the risk of developing liver steatosis, or fatty liver. In a study published in PNAS researchers from Karolinska Institutet in Sweden show how a larger intake of inorganic nitrate, which occurs naturally in many types of vegetable, reduces accumulation of fat in the liver.
Boys with good motor skills are better problem-solvers than their less skillful peers, a new study from Finland shows. In contrast to previous studies, the researchers found no association between aerobic fitness or overweight and obesity with cognitive function in boys.
African-American women undergo more physical "wear-and-tear" during the first year after giving birth than Latina and white women, a consequence that may have long-lasting health effects, according to a study of a diverse group of more than 2,400 low-income women.
A new compound that targets a receptor within sarcoma cancer cells shrank tumors and hampered their ability to spread in mice and pigs, a study from researchers at the University of Illinois reports.
Even among sleep researchers, it is a widely held belief that sleep quality can be improved by avoiding exercise in the evening.
Associate Professor Janelle Ayres has been awarded $1.8 million over two years by the NOMIS Foundation to study health as an active process in which microbes--including the trillions of microorganisms that call the human body home--initiate interactions that promote the health of the host.
New research suggests that exercise is a key factor in reducing colorectal cancer risk after weight loss. According to the study, physical activity causes beneficial changes in the bone marrow. The study is published ahead of print in the American Journal of Physiology--Endocrinology and Metabolism.
The Nobel Lectures held by the laureates of the 2018 Nobel Prize in Physiology or Medicine saw Aula Medica at Karolinska Institutet filled to the brink. In addition to 1,000 audience members in the auditorium, people around the world were able to watch the live broadcast when James P. Allison and Tasuku Honjo talked about their research, the results of which have led to the ground-breaking immune checkpoint therapy for cancer treatment.
The neurodegenerative disease ALS causes motor neuron death and paralysis. However, long before the cells die, they lose contact with the muscles as their axons atrophy.
Sixty years after melatonin was isolated and with more than 23,000 published studies showing the many functions of this hormone secreted by the pineal gland, guidelines should be discussed and established for its therapeutic use.
For the first time, a research team at Lund University in Sweden has successfully reprogrammed mouse and human skin cells into immune cells called dendritic cells.
A new book is the first to encompass the vast history of how living things procreate, from the banks of the ancient Nile to the fertility clinics of today.
What can seashells, lightning and the coastline of Britain teach us about new drugs for cancer?
Australian researchers have found a gene which when removed could allow a person to eat as much as they want but not get fat. The study results were published in the latest issue of the journal European Molecular Biology Organization (EMBO) Reports.
