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.
Volcano Corporation today announced the pricing of its offering of $100 million aggregate principal amount of 2.875 percent convertible senior notes due September 1, 2015 registered under the Securities Act of 1933, as amended. Prior to June 1, 2015, the notes will be convertible only upon certain circumstances.
Tengion, Inc., a leader in regenerative medicine, announced today the publication of a key study in the American Journal of Physiology Renal Physiology by researchers at Tengion. In the study, rodents with chronic kidney disease (CKD) were treated with healthy kidney cells to catalyze the regeneration of functional kidney tissue and delay disease progression, as evidenced by extended survival, improved kidney filtration, and reduced severity of kidney tissue pathology.
Scientists from The Scripps Research Institute have solved a long-standing mystery of how cells conduct "quality control" to eliminate the toxic effects of a certain kind of error in protein production. The findings may lead to a better understanding of a host of neurodegenerative diseases.
Brain Tunnelgenix Technologies Corp. announced today that the U.S. Food and Drug Administration (FDA) has granted the company clearance to market its Abreu BTT 700 System for continuous temperature monitoring.
Consuming energy drinks during team sports could help young people perform better, a study suggests.
Sports scientists found that 12-14 year olds can play for longer in team games when they drink an isotonic sports drink before and during games.
In the latest issue of the journal Nature, Miguel Godinho Ferreira, Principal Investigator at the Instituto Gulbenkian de Ciência (IGC) in Portugal, lead a team of researchers to shed light on a paradox that has puzzled biologists since the discovery of telomeres, the protective tips of chromosomes: while broken chromosome ends generated by DNA damage (such as radiation or cigarette smoke) are quickly joined together, telomeres are never tied to each other, thus allowing for the correct segregation of the genetic material into all cells in our body.
An ongoing research initiative into the health effects of botanical estrogens will get an $8 million boost from the National Institutes of Health.
Kansas State University has been a issued a patent for a plentiful and noncontroversial source of stem cells from a substance in the umbilical cord.
The first study to demonstrate that obesity can directly accelerate the progression of acute lymphoblastic leukemia (ALL) has been conducted at The Saban Research Institute of Childrens Hospital Los Angeles and will be published in Cancer Prevention Research, on October 5, 2010. Obesity has been associated with an increased incidence of many cancers, including leukemia, but it has been unknown whether the increase in incidence was a direct effect of obesity or associated with genetic, lifestyle, health, or socio-economic factors.
A new study from Sweden's Karolinska Institutet suggests that bipolar disorder or manic-depressive disorder does not increase the risk of committing violent crime. Instead, the over-representation of individuals with bipolar disorder in violent crime statistics is almost entirely attributable to concurrent substance abuse.
Two new studies have shed more light on how smoking may damage fertility, and give further weight to advice that mothers and fathers-to-be should stop smoking before attempting to conceive. The research is published online in the reproductive medicine journal Human Reproduction today (Wednesday 8 September).
Researchers from GE Global Research have been awarded a $538,000 human microbiome project from the National Institutes of Health (NIH) to develop new technology that would allow for the study of individual cells growing inside and outside the body believed to have a significant impact on human health.
UT Southwestern Medical Center researchers have identified unique metabolic properties that allow a specific type of stem cell in the body to survive and replicate in low-oxygen environments.
Scripps Research Institute scientists have identified two proteins with potential to be important targets for research into a wide range of health problems, including pain, deafness, and cardiac and kidney dysfunction.
The aluminium content of a range of the most popular brands of infant formulas remains high, and particularly so for a product designed for preterm infants and a soya-based product designed for infants with cow's milk intolerances and allergies, researchers have found.
Biologists at the University of California, Riverside have found that voluntary activity, such as daily exercise, is a highly heritable trait that can be passed down genetically to successive generations.
StemCells, Inc. announced today that its technology was recently used by independent researchers to achieve the first genetically engineered rat derived from rat embryonic stem (ES) cells. This breakthrough, published this month in the international peer-reviewed journal Nature, opens the door to the types of genetic manipulations previously only possible in mice, and paves the way for modeling a broader range of human diseases with the rat.
Girls eating a high-fat diet during puberty, even those who do not become overweight or obese, may be at a greater risk of developing breast cancer later in life, according to Michigan State University researchers.
Genes that affect the immune system and link it to Parkinson’s disease have been uncovered. This paves the way for new drug development in Parkinson’s disease – a serious, degenerative disease of the nerves that leads to tremors and muscle stiffness and eventually complete loss of movements. There is currently no cure for PD.
For competitive bicyclists with goals - whether competing in the Tour de France or aiming for the podium at a local race - faster cycling comes from training regimens based on various zones of exercise intensity. New research from exercise scientists at the University of New Hampshire has found that effective training regimens, which generally are created after expensive, time-consuming laboratory tests, can be developed from a relatively simple, do-it-yourself test.
