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.
The production of fat in the human body is essentially regulated by gut hormones.
Don't be afraid to toss a handful of raisins or dried apples in your Thanksgiving stuffing this year -- a new Penn State study has found that dried fruit may be connected with better health.
A hormone that can suppress food intake and increase the feeling of fullness in mice has shown similar results in humans and non-human primates, says a new study published today in eLife.
According to the World Health Organization, obesity has nearly tripled worldwide since 1975. In 2016, for example, more than 1.9 billion adults were categorized as overweight. Of these, more than 650 million had obesity.
Cells of higher organisms use cell organelles to separate metabolic processes from each other. This is how cell respiration takes place in the mitochondria, the cell’s power plants.
In social hierarchy, rank is a condition that is not exclusively claimed by human beings. In the animal world, male peacocks have vividly colored plumes to show dominance, while underwater, male fish exhibit an array of vivid colors to do the same.
GAIN4CROPS is developing novel disruptive technologies to overcome one of the main constraints of photosynthesis: the photorespiration, a process that reduces CO2 assimilation efficiency, and thus biomass yield and agricultural productivity.
Understanding the impacts of global warming on phytoplankton- the foundation of marine ecosystems -is critical to predicting changes in future biodiversity, ocean productivity, and ultimately fisheries production.
Max Planck Institute for Plant Breeding Research (MPIPZ) and University of Cologne researcher Takaki Maekawa and colleagues have discovered that plants have independently evolved a family of immune proteins that are strikingly similar to animals.
A new study from Lawson Health Research Institute, Western University and University of Alberta suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites - small molecules broken down in the human body through the process of metabolism.
"Wound healing is one of the most complex biological processes," writes Professor Kazumitsu Sugiura and Dr Kenta Saito from Fujita Health University, Japan, in their article recently published in Nature's Scientific Reports.
Research from Saint Louis University finds that high fat or "ketogenic" diets could completely prevent, or even reverse heart failure caused by a metabolic process.
To identify new potential therapeutic targets for SARS-CoV-2, a team of scientists at the New York Genome Center, New York University, and the Icahn School of Medicine at Mount Sinai, performed a genome-scale, loss-of-function CRISPR screen to systematically knockout all genes in the human genome.
As medical professionals and scientists work to design new therapies for cancer, they come across a range of difficulties.
Personalized treatment options for patients with lung cancer have come a long way in the past two decades. For patients with non-small cell lung cancer, the most common subtype of lung cancer and the leading cause of cancer-related death worldwide, two major treatment strategies have emerged: tyrosine kinase inhibitors and immune checkpoint inhibitors.
Regular cannabis exposure in rats during pregnancy may cause their offspring to have long-term cognitive deficiencies, asocial behavior, and anxiety later in adulthood.
In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -- dopamine and serotonin -- are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.
Volume 11, Issue 28 of Oncotarget features "Development and comprehensive characterization of porcine hepatocellular carcinoma for translational liver cancer investigation" by Gaba et, al. which reported that reliable development of Oncopig HCC cell lines was demonstrated through hepatocyte isolation and Cre recombinase exposure across 15 Oncopigs.
With a nearly $2.6 million grant from the National Institutes of Health, Michigan State University researchers are using nanoscopic particles to turn the body's own cells into weapons that cancer won't see coming.
The vast majority of bacteria in the world live on surfaces by forming structures called "biofilms". These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that scientists describe them as "cities".
