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.
When developing a new drug, the first question is, “does it work?” and the second question is, “is it harmful?”
Scientists have found that botulinum toxin—commonly known as Botox—can expose the inner workings of the brain, in addition to smoothing out wrinkles.
Using electron cryo-tomography, researchers have created the first high-resolution 3D image of the sarcomere.
A study by researchers proposes that disease-driving B cells—a kind of white blood cell—have a role in the development of non-alcoholic fatty liver disease.
Human cells typically transcribe half of their roughly 20,000 genes into RNA molecules at any given time. Just like with proteins, the function of those RNA species not only relies on their abundance but also their precise localization within the 3D space of each cell.
The production of high-value pharmaceutical proteins in plants provides benefits over other manufacturing techniques.
A team of researchers led by Professor Yaakov Nahmias, director of the Grass Center for Bioengineering at the Hebrew University of Jerusalem and founder of Tissue Dynamic, introduced a new technological approach that has the potential to rapidly develop new drugs without the need for animal experiments.
A new study from the University of California, Irvine shows that compounds in both green and black tea relax blood vessels by activating ion channel proteins in the blood vessel wall.
Studies of the microbiome in the human gut focus mainly on bacteria. Other microbes that are also present in the gut -- viruses, protists, archaea and fungi -- have been largely overlooked.
Researchers have demonstrated how one combination of therapies may be beneficial for patients with mitochondrial respiratory chain disorders.
An impressive body of evidence published this week reveals the answer to a mystery that has puzzled plant scientists for more than 30 years.
In recent years, hummus has become a pop culture food phenomenon, drawing praises from dieticians for the health benefits and chefs for the flavor.
The National Cancer Institute's Genomic Data Commons (GDC), launched in 2016 by then-Vice President Joseph Biden and hosted at the University of Chicago, has become one of the largest and most widely used resources in cancer genomics, with more than 3.3 petabytes of data from more than 65 projects and over 84,000 anonymized patient cases, serving more than 50,000 unique users each month.
Tohoku University scientists have shown that neuronal and glial circuits form a loosely coupled super-network within the brain.
In the same way that Lego pieces can be arranged in new ways to build a variety of structures, genetic elements can be mixed and matched to create new genes, according to new research.
About one in five individuals do not have the α-actinin-3 protein in their muscle fiber.
In recent time, HBO's highly acclaimed and award-winning miniseries Chernobyl highlighted the horror of nuclear power plant accident, which happened in Ukraine in 1986.
The research team that developed a biosensor that first recorded that a distinct gradient of the plant growth hormone gibberellin correlated with plant cell size has now revealed how this distribution pattern is created in roots.
Researchers have designed a program that allows the complete study of the SARS-CoV-2 mutant spectrum by ultrasequencing.
Plastic, with its unabated global production, is a major and persistent contributor to environmental pollution. In fact, the accumulation of plastic debris in our environment is only expected to increase in the future.
