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 influential article in the journal Progress in Neurobiology provided one of the first comprehensive reviews of how estrogen potentially can protect against Alzheimer's disease and other neurological disorders.
Glioblastoma, the most common and lethal form of brain cancer and the disease that killed Massachusetts Senator Ted Kennedy, resists nearly all treatment efforts, even when attacked simultaneously on several fronts. One explanation can be found in the tumor cells' unexpected flexibility, discovered researchers at the Salk Institute for Biological Studies.
Despite what you might have heard, genetic sequencing alone is not enough to understand human disease. Researchers at Duke University Medical Center have shown that functional tests are absolutely necessary to understand the biological relevance of the results of sequencing studies as they relate to disease, using a suite of diseases known as the ciliopathies which can cause patients to have many different traits.
Ultrasound is a valuable tool that allows doctors to diagnose and treat patients quickly and accurately. It's been around for decades, but there has been revolutionary change in the technology in recent years, making the machines smaller, cheaper and smarter.
A team of researchers at Boston University School of Medicine have been awarded a five-year, $7.7 million grant from the National Institutes of Health's National Institute of Allergy and Infectious Diseases to explore how chronic inflammation can lead to systemic diseases.
Archimedes Inc., a healthcare modeling company, announced today that it has entered into a Research Collaboration Agreement with the U.S. Food and Drug Administration (FDA) to develop a computer model of clinical trials evaluating weight loss medications. The model will be used to obtain a better understanding of the benefits of weight loss against the long-term risks of cardiovascular outcomes in patients treated with weight loss drugs.
A team of scientists at The Scripps Research Institute and the University of Virginia has determined the structure of the protein package that delivers the genetic material of the human immunodeficiency virus to human cells.
Using chemical compounds found in a Japanese plant as a lead and the clever application of ultraviolet light, a Scripps Research Institute team has created a unique library of dozens of synthetic compounds to test for biomedical potential. Already, one of the compounds has shown great promise in inhibiting replication of HIV particles and fighting inflammation.
Frigid weather may seem like a good excuse to avoid workouts, stay inside and overindulge in comfort foods. However, health experts from the University of Missouri have found that these tendencies leave most people feeling less content during the winter months. MU researchers say people should establish new traditions to increase happiness and avoid wintertime woes.
Researchers from Boston University School of Medicine have for the first time shown that reduced vitamin D absorption in patients with quiescent Crohn's disease may be the cause for their increased risk for vitamin D deficiency.
Researchers have identified how the hormones progesterone and estrogen interact to increase cell growth in normal mammary cells and mammary cancers, a novel finding that may explain why postmenopausal women receiving hormone replacement therapy with estrogen plus progestin are at increased risk of breast cancer.
Following a successful Phase 1 study for safety, researchers at MassBiologics of the University of Massachusetts Medical School today announced the beginning of a Phase 2 clinical trial testing the ability of a human monoclonal antibody they developed to prevent hepatitis C virus infection of a donor liver in transplant patients.
It's called post-operative cognitive decline, a syndrome in which patients experience memory loss or other forms of cognitive dysfunction after surgery or critical illness.
In three papers in the January and February issues of the Journal of General Physiology, Don Hilgemann and colleagues have extensively characterized a previously unidentified process by which up to 75% of the cell plasma membrane can be reversibly endocytosed.
A new magnetic pill system developed by Brown University researchers could solve the problem by safely holding a pill in place in the intestine wherever it needs to be.
Today scientists at The University of Texas Health Science Center San Antonio reported how this essential function of the distal nephron is regulated. They demonstrated that sodium handling by the distal nephron is under the control of a local regulatory system.
A study from the University of Gothenburg, shows that women with polycystic ovary syndrome (PCOS) have aberrations in their adipose tissue.
Adults who take one of the world's most commonly prescribed sleep medications are significantly more at risk for nighttime falls and potential injury, according to a new study by the University of Colorado at Boulder.
The Scripps Research Institute and Vanderbilt University have formed a partnership to advance science at the interface of chemistry and medicine, the institutions announced today.
Living a traumatic experience favours the persistence of fear associated with an aversive stimulus, known as fear conditioning and such effect, in mice, can be suppressed with a single dosis of 7,8-Dihydroxyflavone, a type of flavonoid which boosts the ability to acquire new emotional learnings.
