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.
Researchers at the University of Pittsburgh School of Medicine and Arts & Sciences have designed a more effective version of an FDA-approved epilepsy drug with the potential for fewer side effects, according to a study published on March 22 in Molecular Pharmacology. The experimental agent also could prove to be a treatment for tinnitus and other disorders caused by volatile neural signaling.
A University of Guelph professor has uncovered the "secret" to staying strong as we age - superb fitness.
Spanish researchers have analysed how the sodium lost through sweat during a marathon influences the maintenance of stable and physiologically sound conditions that allow the body to carry out its functions. Excessive electrolyte loss may lead to a medical problem known as hyponatraemia.
In this interview, News Medical speaks Tobias Pusterla, Ph.D from BMG Labtech about versatile automated microplate sample screening applications.
Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down's syndrome, suggests new research carried out in mice at the University of Cambridge. In a study published today in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing - and in many cases completely fixing - the embryo.
MedUni Vienna has made a crucial development in the treatment of Multiple Sclerosis (MS): Together with his team and the research group led by Gernot Schabbauer, international partners from Australia, Germany and Sweden, Christian Gruber, Chief Researcher at the Center for Physiology and Pharmacology has demonstrated in an animal model that, following treatment with a specially synthesized plant peptide (cyclotide), there is no further progression of the usual clinical signs of multiple sclerosis.
According to the World Health Organization, approximately 37 million people are living with HIV. Antiviral medications are used to control the disease and prevent its progression to AIDS.
A team led by scientists at The Scripps Research Institute and the Salk Institute for Biological Studies has discovered two enzymes that appear to play a role in metabolism and inflammation—and might someday be targeted with drugs to treat type 2 diabetes and inflammatory disorders.
Researchers at the University of Vermont College of Medicine have made a discovery that helps explain how we know when to empty our bladders and may lead to new therapeutic interventions for bladder dysfunction.
The gene UBE3A plays a critical role in early neurological development. If UBE3A is overexpressed - or if the enzymatic function of UBE3A protein is hyperactive - autism ensues. A lack of functional UBE3A causes Angelman syndrome (AS), a neurodevelopmental disorder characterized by severe developmental delay, motor deficits, absence of speech, and, in most cases, epilepsy.
Higher concentrations of the common plastics chemical and environmental pollutant Bisphenol A, or BPA, in a pregnant mother's blood may be a contributing factor in preterm births, according to a new study from The University of Texas Medical Branch at Galveston.
If a patient is ill and takes drugs for that illness, these drugs often lead to further illnesses and complications. This affects millions of people throughout the world.
University of Alabama at Birmingham researchers have made a microscopic snapshot of the early renal lipid changes in acute kidney injury, using the laser-scanning method called MALDI tissue imaging to localize the changes.
University of Oregon scientists have looked into the brains of living mice to see in real time the processing of sensory information and generation of behavioral responses.
Why humans and other animals sleep is one of the remaining deep mysteries of physiology. One prominent theory in neuroscience is that sleep is when the brain replays memories "offline" to better encode them ("memory consolidation").
Many of the drugs we use in hospitals – antibiotics, antifungals and anti-cancer drugs, to name but a few – are produced by bacteria that live in the soil beneath our feet.
Sphere Medical, an innovator company in critical care monitoring and diagnostics equipment, today announces the appointment of Professor Michael Grocott to its Medical Advisory Board.
Lesbian, gay, bisexual, transgender and queer (LGBTQ) patients who are also racial and ethnic minorities suffer significant health disparities, while facing more complicated challenges than white LGBTQ or racial and ethnic minority patients alone.
A new study published in Physiological Genomics suggests that the brain shows signs of aging earlier than old age. The study found that the microglia cells—the immune cells of the brain—in middle-aged mice already showed altered activity seen in microglia from older mice.
In an article published online ahead of print on Feb. 19, 2015 in the Journal of Biological Chemistry, investigators at the Medical University of South Carolina and the Ralph H. Johnson VA Medical Center report findings from in vitro and in vivo studies that elucidate the mechanisms underlying the impaired ciliogenesis and abnormal kidney development characteristic of polycystic kidney disease (PKD).
