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.
It has long been known that psychostimulant drugs have the paradoxical effect of reducing hyperactivity. [Psychostimulant drugs include methylphenidate - known by the trade names Ritalin, Concerta, and Methylin - and methamphetamine]. Since the mid-1950s, millions of children and adults have been prescribed stimulant medications to control attention deficit hyperactivity disorder.
Parkinson's disease researchers at the University at Buffalo have discovered how mutations in the parkin gene cause the disease, which afflicts at least 500,000 Americans and for which there is no cure.
A new study published in the journal Respirology reveals that a high level of soft drink consumption is associated with asthma and/or chronic obstructive pulmonary disease (COPD).

Researchers have long known that specific parts of the brain activate when people view particular images. For example, a region called the fusiform face area turns on when the eyes glance at faces, and another region called the parahippocampal place area does the same when a person looks at scenes or buildings. However, it's been unknown whether such specialization also exists for visual working memory, a category of memory that allows the brain to temporarily store and manipulate visual information for immediate tasks.
The Swedish medical university, Karolinska Institutet, has received a grant of 1.6 million Euro from the Stichting af Jochnick Foundation for research into the fundamental causes of diabetes. The grant will make it possible to use unique methods to study how the release of insulin is regulated in living organisms - and this will create new opportunities for developing more effective drugs against diabetes.
To explore the most intricate structures of the brain in order to decipher how it functions - Stefan Hell's team of researchers at the Max Planck Institute for Biophysical Chemistry in G-ttingen has made a significant step closer to this goal. Using the STED microscopy developed by Hell, the scientists have, for the first time, managed to record detailed live images inside the brain of a living mouse.
UNC researchers have discovered how the genetic defect underlying one of the most common congenital heart diseases keeps the critical organ from developing properly. According to the new research, mutations in a gene called SHP-2 distort the shape of cardiac muscle cells so they are unable to form a fully functioning heart.
Coronary patients with low levels of an immune system antibody called anti-PC, which neutralises parts of the "bad" cholesterol, run a greater risk of suffering complications following an acute cardiac episode and thus of premature death.
Both subjective and objective cognitive impairment are highly common among non-demented elderly Swedes, with an overall prevalence of 39 percent and 25 percent respectively, according to a nationwide twin study by researchers at the Aging Research Center of Karolinska Institutet, Sweden.
One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.
Could the use of vitamin and mineral supplements in a regular diet help to reduce the risk of colon cancer and protect against carcinogens? A study published in the Canadian Journal of Physiology and Pharmacology (CJPP) found that rats given regular multivitamin and mineral supplements showed a significantly lower risk of developing colon cancer when they were exposed to carcinogens.
New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.
We all know that it can take a little while for our hearing to bounce back after listening to our iPods too loud or attending a raucous concert. But new research at the University of Michigan Health System suggests over-exposure to noise can actually cause more lasting changes to our auditory circuitry - changes that may lead to tinnitus, commonly known as ringing in the ears.
With the U.S. Food and Drug Administration's recent approval of transcatheter aortic valve replacement (TAVR) for patients with aortic valvular stenosis, the American College of Cardiology Foundation (ACCF), along with the American Association for Thoracic Surgery (AATS), the Society for Cardiovascular Angiography and Interventions (SCAI) and the Society of Thoracic Surgeons (STS), today released an expert consensus document to provide important guidance on its use.
A team of scientists from the University of Utah and the University of California at San Francisco has discovered that the mutation of a gene encoding a ketone body transporter triggers accumulation of fat and other lipids in the livers of zebrafish.
A new study in the Journal of General Physiology uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) "walk" along their actin track.
Age-related delays in neural timing are not inevitable and can be avoided or offset with musical training, according to a new study from Northwestern University. The study is the first to provide biological evidence that lifelong musical experience has an impact on the aging process.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for patent application number 12/813,448, covering the company's proprietary second generation lipid nanoparticle (LNP) platform, including the "MC3" lipid.
A new family of proteins which regulate the human body's 'hypoxic response' to low levels of oxygen has been discovered by scientists at Barts Cancer Institute at Queen Mary, University of London and The University of Nottingham.
