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.
Salk Institute researchers have now found a pattern of DNA damage that is unique to brain cells derived from individuals with a single form of autism spectrum disorder (ASD) called macrocephalic ASD. The study, published in the journal Cell Stem Cell in January 2020, may offer an explanation about the developmental misstep that caused this disease.
When it comes to finding new treatments for disease, reinventing the wheel is not always necessary - drugs already in use for other conditions may do the job.
Many diseases arise from abnormalities in our capillaries, tiny exquisitely branching blood vessel networks that play a critical role in tissue health.
A study in rats examines a pathway through which protein deficiency during pregnancy leads to fat accumulation in the liver and increased risk of liver damage.
The process of developing new drugs is both difficult and costly. It is estimated that of all the drug candidates which start out on their testing journey, less than 14% actually make it to the clinical scene and receive approval by the US Food and Drug Administration (FDA).
Researchers have made a device that could sour the waters of the seas for microbes and also detect which of these could develop antimicrobial resistance. This could quantify the threat they pose to the ecosystems. This portable device and the trial with it were reported in the latest issue of the journal Scientific Reports. The study was titled, “Electrical impedance as an indicator of microalgal cell health.”
Individuals with a history of early life adversity are disproportionately prone to opioid addiction. A new UCI-led study reveals why.
In this interview, discussing the effects of mycoplasma contamination on cell cultures and the development of rapid detection kits that provide answers in just thirty minutes.
Mitochondria are organelles that are found in the eukaryotic cells. A place of cellular respiration, they are the cells' "batteries" and play a major role in energy metabolism and intercellular communication.
Promoting the signaling pathway of reelin -an essential extracellular protein for the neuronal migration and synaptic plasticity- could be an effective therapeutical strategy to counterbalance the main cognitive, biochemical and behavioral alterations seen in Alzheimer's and other pathologies associated with Tau protein, as shown in a new study with animal models -published in the journal Progress in Neurobiology.
The human immune system uses two pre-programmed strategies to tackle infection. One is fever, a resistance mechanism that tries to eliminate a pathogen by raising the body's temperature.
Sara Piccirillo, PhD, is passionate about finding a way to beat glioblastoma, the most aggressive type of brain cancer.
After showing that a 10-week therapeutic horseback riding intervention reduced irritability and hyperactivity while improving the social communication skills of youth diagnosed with autism spectrum disorder, University of Colorado Anschutz Medical Campus researcher and Children's Hospital Colorado psychologist, Dr. Robin Gabriels, has received a $2.5 million grant to investigate why the therapy works.
After diagnosis, only thirty percent of glioblastoma (an aggressive brain cancer) patients have survived more than two years.
New research by Dorothy P. Schafer, PhD, at the University of Massachusetts Medical School, reveals the molecular process in which synaptic connections in the brain are damaged in multiple sclerosis and how this contributes to neurodegenerative symptoms.
A new study by the University of Barcelona concluded that irregularity in eating schedules during the weekend, named by the authors as eating jet lag, could be related to the increase of body mass index (BMI), a formula that measures weight and height to determine whether someone's weight is healthy.
Biophysicists from the MIPT Center for Molecular Mechanisms of Aging and Age-Related Diseases have teamed up with colleagues from Canada, the U.S., Japan, France, and Germany to shed light on the structure and functioning mechanism of the CysLT receptors, which regulate inflammatory responses associated with allergic disorders.
After years of research on cell surface receptors called Frizzleds, researchers at Karolinska Institutet in Sweden provide the proof-of-principle that these receptors are druggable by small molecules. The results, which are published in the scientific journal Nature Communications, open for new strategies to treat different types of cancer.
Researchers at Chalmers University of Technology and Gothenburg University in Sweden have achieved something long thought almost impossible - counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a new analysis method, they showed that the brain regulates its signals using glutamate in more ways than previously realised.
Positron Emission Tomography, or PET scanning, a technique for tracing metabolic processes in the body, has been widely applied in clinical diagnosis and research spanning physiology, biochemistry and pharmacology.
