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.
An innovative new study is set to examine if changing our mealtimes to earlier or later in the day could reduce the risk of developing Type 2 diabetes.
The hallmarks of cancer include rapid cell-reproduction and metabolic activity. But these processes also lead to increased cellular stress and oxidation, and the risk of cell death.
There are many components to aging, both mental and physical. When it comes to the infrastructure of the human body - the musculoskeletal system that includes muscles, bones, tendons and cartilage - age-associated decline is inevitable, and the rate of that decline increases the older we get.
A compound developed at Oregon Health & Science University appears to protect nerve fibers and the fatty sheath, called myelin, that covers nerve cells in the brain and spinal cord.
Like a failing fuel pump that causes a loss of engine power in a car, a diseased heart can take a serious toll on the body's performance. For some patients, tasks like walking up a flight of stairs or walking across a room eventually turn into exhausting endeavors.
Thanks to major progress in the understanding and management of rare congenital diseases and syndromes, many patients with these rare disorders are now living longer lives.
Almost 18,000 Americans experience traumatic spinal cord injuries every year. Many of these people are unable to use their hands and arms and can't do everyday tasks such as eating, grooming or drinking water without help.
Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".
MDC researchers have developed a new approach to CAR T-cell therapy. The team has shown in Nature Communications that the procedure is very effective, especially when it comes to fighting follicular lymphomas and chronic lymphocytic leukemia, the most common type of blood cancer in adults.
In a large-scale study of electronic health records, Vanderbilt University Medical Center investigators have determined the prevalence of functional seizures and characterized comorbidities associated with them.
CytoDel, Inc., a privately-held corporation, today announces the publication of preclinical data on the Company's lead product, Cyto-111, in the peer-reviewed journal, Science Translational Medicine. The complete text of the article titled, "Neuronal Delivery of Antibodies has Therapeutic Effects in Animal Models of Botulism," can be found here.
Humans have consumed different types of fermented foods - from kimchi to yogurt - for thousands of years.
Yet only recently, with the availability of new scientific techniques for analyzing their nutritional properties and microbiological composition, have scientists begun to understand exactly how the unique flavors and textures are created and how these foods benefit human health.
A research study at the University of Chicago has found that in pregnancy, while the T cell response to a fetus becomes tolerant to allow for successful pregnancy, the part of the immune system that produces antibodies (known as the humoral response) becomes sensitized, creating memory B cells that can later contribute to the rejection of a transplanted organ.
Despite the progress made in managing asthma and chronic obstructive pulmonary disease (COPD), poorly controlled symptoms for both respiratory diseases can lead to severe shortness of breath, hospitalizations or even death.
As the covid-19 pandemic heads for a showdown with vaccines it's expected to lose, many experts in the field of emerging infectious diseases are already focused on preventing the next one.
UT Southwestern scientists have adapted a classic research technique called forward genetics to identify new genes involved in autism spectrum disorder (ASD).
Advances in neuroscience and engineering have generated great hope for Luke Skywalker-like prosthetics: robotic devices that are almost indistinguishable from a human limb.
Female rats that inhaled vaporized cannabis daily for a month developed a blunted physiological response to stress, according to a new study by Washington State University researchers.
Researchers of the "Cell Biology and Physiology-LABRET" group of the University of Malaga (UMA), together with the Networking Biomedical Research Center in Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN), have described a new genetic skeletal disorder based on a precision medicine strategy.
Poop samples are an effective, non-invasive tool for monitoring gray whale reproduction, stress and other physiological responses, a new study from Oregon State University shows.
