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.
As the northern hemisphere experiences shorter and colder days, individuals who prefer morning workouts may encounter increased difficulty in getting up and running.
Double haploid technology can dramatically accelerate crop breeding with specifically chosen genetic traits.
The sequencing of the human genome promised a revolution in medicine, but scientists soon realized that a genetic blueprint alone does not show the body in action.
An innovative KI study published in the Journal of Clinical Investigations found that red blood cells exposed to oxygen deficiency safeguard against myocardial infarction. The research also showed that a nitrate-rich vegetable diet boosts the protective effect.
Studying the complex interactions between synaptic nerve endings as well as their development has now become much easier.
Apiin, a natural compound found in high amounts in parsley and celery, is thought to have important medicinal properties.
More than 2,000 canine genomes have been generated and examined by an international research consortium.
A German-American research team headed by Prof. Dr. Bernd Fakler from the Faculty of Medicine at the University of Freiburg demonstrated the major influence of Noelin1-3 proteins on learning and memory formation in the mammalian brain.
Early social and environmental exposures can have large and lasting effects on child development and adult health.
The historically high heat waves that gripped the southwest United States and southern Europe this summer are causing problems for more than just humans.
Researchers have developed a synthetic extracellular matrix (ECM) that can facilitate the development of a miniature endometrium in a dish for at least two weeks.
Tumor cells are known to be fickle sleeper agents, often lying dormant in distant tissues for years before reactivating and forming metastasis. Numerous factors have been studied to understand why the activation occurs, from cells and molecules to other components in the so-called tissue microenvironment.
Bacteria make up more than 10% of all living things but until recently we had little realization that, as in humans, soil bacteria have internal clocks that synchronize their activities with the 24-hour cycles of day and night on Earth.
Indiana University researcher Daniella Chusyd is studying human aging in an unlikely way: through elephants.
Gastrointestinal and digestive issues impact roughly 3 million people across the United States alone, and that number is growing.
Right from impacting how the human body stores fat to how the brain regulates appetite, hundreds of genes, together with environmental factors, jointly identify weight and body size.
In a step forward in the development of genetic medicines, researchers at Children's Hospital of Philadelphia (CHOP) and the Perelman School of Medicine at the University of Pennsylvania have developed a proof-of-concept model for delivering gene editing tools to treat blood disorders, allowing for the modification of diseased blood cells directly within the body.
Animals and humans coexist with a vast array of microorganisms known as the microbiome, forming an intricate relationship that can range from mutually beneficial to pathogenic.
Even though infections can be presented with several different symptoms, one common symptom is known to be the loss of fat and muscle, a process known as wasting.
The energy supply in the body has been regulated by the pancreas, located behind the stomach. This mechanism happens by secreting proteins (enzymes) accountable for glucose–the body’s primary fuel–reaching other organs when needed and in the exact amount.
