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.
In a vertical climb to avoid collision with a towering mountain, a plane ejects cargo to gain altitude. Investigators at the University of Minnesota showed that cancer cells perform similar feats in escaping the killing effects of radiation.
When Bacillus subtilis cells are deprived of an amyloid protein, they show a range of cytological dysfunctions and anomalies that cause their premature death.
Excess white fat causes obesity, which in turn can drive metabolic diseases that are growing at epidemic rates around the world.
Obesity has been shown to place physical stress on the body, but new research suggests that excess weight may also cause mental fatigue.
Wheat sustains the world. The FAO has stated that wheat is one of the main crops in the world, both in terms of scope and production, and it is also one of the rich sources of vegetable protein and carbohydrates in the human diet.
Chronic pancreatitis, or persistent inflammation of the pancreas, is a known risk factor that leads to the development of pancreatic cancer, which is the third-deadliest cancer in the United States.
In recent years, RNA molecules, with the ability to affect or turn off pathogenic genes, have become promising drug candidates in several areas.
The simplicity of urine sampling has been combined with the excellent sensing abilities of CRISPR to improve diagnostic testing for kidney transplant patients.
UC Davis Health researchers have developed a computer model to screen drugs for unintended cardiac side effects, especially arrhythmia risk.
In a new study, published in the journal Nature, Michigan State University scientists show how plant genes select which microbes get to live inside their leaves in order to stay healthy.
Five years ago, researchers from the Centre for Research in Agricultural Genomics led by the CSIC Research Professor Paloma Mas made the breakthrough discovery that the circadian clocks in the growing tip of the plant shoot function in a similar way to the clocks in the mammalian brain, which in both cases are able to synchronize the daily rhythms of the cells in distal organs.
VRAC/LRRC8 chloride channels play a crucial role in the transport of neurotransmitters, amino acids, and cytostatics.
A minute chemical modification on one of the most copious and vital proteins in cells—actin—has been a mystery as its function is not fully known.
When we are exposed to sufficient cold or exercise, small clusters of brown fat cells in our bodies begin to burn up energy.
A team of University of Massachusetts Amherst food scientists has been awarded a grant from the Good Food Institute to create tasty, plant-based, protein-rich food that's similar in texture to whole chicken, pork or beef.
In satellite photos of the Earth, clouds of bright green bloom across the surface of lakes and oceans as algae populations explode in nutrient-rich water. From the air, the algae appear to be the primary players in the ecological drama unfolding below.
Ion channels that permit potassium and sodium ions to move in and out of cells are essential for the function of the brain and heart, and also for neuronal “firing” in the central nervous system.
Thanks to CRISPR-based genetic screens, researchers were able to detect genes that play a major role in lung cancer metastasis, cancer immunotherapy, sickle-cell anemia, and a host of other medical disorders.
New breakthrough in breast cancer could enable the development of better approaches to prevent the spread of cancer cells to other organs in the body, thereby effectively bringing down mortality in patients suffering from breast cancer.
Researchers have proposed a new high-throughput, multigenerational time-lapse imaging platform, capable of single-cell screening.
