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 Olympus FluoView® FVMPE-RS, a dedicated multiphoton microscope system, enables high-precision, ultra-fast scanning and stimulation, allowing researchers to see deep within specimens, take measurements at the highest speeds, and capture images even when working under the most demanding conditions.
Backed by research that demonstrates significant health benefits as well as unparalleled taste that meets consumer needs, food ingredients are taking center stage as thousands of experts from around the world converge to discuss the state of global health and nutrition at the leading international nutrition conference taking place this week in Spain.
LifeSensors, Inc., a biotech company developing cutting-edge technologies for studying the ubiquitin pathway, has been awarded a U.S. patent for the development of novel, fluorescent di- and poly-ubiquitin deubiquitinase substrates (US 8,518,660).
Brown University researchers have traced a genetic deficiency implicated in autism in humans to specific molecular and cellular consequences that cause clear deficits in mice in how well neurons can grow the intricate branches that allow them to connect to brain circuits. The researchers also show in their study (online Sep. 12, 2013, in Neuron) that they could restore proper neuronal growth by compensating for the errant molecular mechanisms they identified.
Thanks to medical advances, better treatments and new drugs not available a generation ago, the average American born today can expect to live 3.8 years longer than a person born two decades ago.
Transplanting fat may treat such inherited metabolic diseases as maple syrup urine disease (MSUD) by helping the body process the essential amino acids that these patients cannot, according to Penn State College of Medicine researchers.
Evidence from people with heart disease strongly supports the existence of the molecular link first discovered in laboratory mice between the body's natural circadian rhythms and cardiac arrest or sudden cardiac death (SCD) - the No. 1 cause of death in heart attacks, a scientist said here today.
Researchers have found abnormal neural function in patients with primary insomnia, which may help explain why these patients find it hard to concentrate on daytime tasks despite the absence of objectively measured cognitive deficits.
Despite tens of thousands of studies in the literature on the thyroid gland, thyroid hormone, and thyroid disease, lack of standardization in study design makes it difficult to compare the results and apply them to the development of improved diagnostic and treatment approaches.
An effort by Rice University to train the neuroengineers of the future has drawn nearly $2.8 million in support from the National Science Foundation (NSF).
Heart research in Chicago will enter a new era Sept. 20 when top researchers from all of Chicago's major academic medical centers meet at the American Heart Association's 2013 Chicago Research Network Symposium.
A University of Iowa physiologist has a new technique to measure the stiffness of the aorta, a common risk factor for heart disease. And it can be as simple as measuring the pulse in your finger.
Many people who survive a heart attack find themselves back in the hospital with a failing heart just years later. And the outcome often is unfavorable, owing to limited treatment options. But scientists at Temple University School of Medicine's Cardiovascular Research Center recently found hope in an unlikely source - stem cells in cortical, or compact, bone.
Among scientists, the role of proteins called sirtuins in enhancing longevity has been hotly debated, driven by contradictory results from many different scientists. But new research at Washington University School of Medicine in St. Louis may settle the dispute.
Mayo Clinic researchers have found a way to resynchronize cardiac motion following a heart attack using stem cells. Scientists implanted engineered stem cells, also known as induced pluripotent stem (iPS) cells, into damaged regions of mouse hearts following a heart attack.
Removing one of the tiniest organs in the body has shown to provide effective treatment for high blood pressure. The discovery, made by University of Bristol researchers and published in Nature Communications, could revolutionise treatment of the world's biggest silent killer.
Several millions of people around the world suffer from insulin deficiencies. Insulin is a hormone, secreted by the beta cells in the pancreas, which plays a major role in the regulation of energy substrates such as glucose.
People with epilepsy could be helped by new research into the way a key molecule controls brain activity during a seizure. Researchers have identified the role played by of a protein - called BDNF - and say the discovery could lead to new drugs that calm the symptoms of epileptic seizures.
Researchers from major universities in the U.S. have developed specific tests to identify cancer biomarkers in patients with dermatomyositis-a systemic inflammatory disease associated with increased risk of malignancy.
