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.
Consuming fewer calories is largely accepted as a way to improve health and lose weight, but a recently published study in Nature Metabolism points to a specific sulfur-containing amino acid cysteine as a key component in weight loss.
A pairing of two experimental drugs inhibits tumor growth and blocks drug-induced resistance in ovarian cancer, according to a preclinical study led by Weill Cornell Medicine investigators.
The Synaptic Physiology laboratory, led by Juan Lerma at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University (UMH) of Elche, has discovered that a specific group of neurons in the amygdala, a brain region involved in emotion regulation, plays a key role in the emergence of conditions such as anxiety, depression, and altered social behavior.
New research has shown how boys being overweight in early childhood or having chickenpox or another infectious disease in infancy may increase their risk of having chronic disease in later life.
Bright afternoon and early evening light exposure in adolescents leads to lower melatonin levels and delays circadian rhythms, instead of protecting against evening light effects. Long-term light history, especially morning exposure, may help align adolescent sleep cycles.
In a comprehensive Genomic Press Innovators & Ideas interview, Dr. Danielle Beckman reveals how her passion for microscopy has evolved into a mission to understand viral impacts on brain health, offering hope for patients suffering from post-viral neurological symptoms.
A new study from UCLA Health has uncovered how inflammation in brain blood vessels exacerbates damage in vascular dementia and demonstrated that targeting this process with a repurposed drug can promote brain repair and functional recovery in mice.
A Caltech-led team has developed a safe, effective, and painless breast imaging technique that incorporates machine learning to help differentiate between suspicious and healthy tissue.
Exercise has been recognized as an extremely effective tool to improve human health— it can have a preventative and even therapeutic effect on non-communicable diseases such as diabetes and cardiovascular diseases.
Capsaicin, the spicy compound in chili peppers, not only influences inflammation, metabolism, and cancer risk but also shapes the gut microbiome in complex, context-dependent ways. This comprehensive review highlights both the therapeutic promise and potential risks of capsaicin, calling for deeper research into its microbiome-mediated effects.
New basic science insights into programmed cell death could offer relief for inflammatory bowel disease.
A research team led by the University of the Basque Country (Euskal Herriko Unibertsitatea, EHU) has identified hundreds of molecular markers in saliva that could reveal the risk of a person developing major diseases such as cancer, cardiovascular diseases, diabetes and neurodegenerative diseases.
The discovery of an unknown organelle inside our cells could open the door to new treatments for devastating inherited diseases.
Hot tubs and saunas can both soothe aching muscles and provide welcome warmth, but hot tubs might offer greater health benefits.
The endothelium lining the valve plays a critical role. It’s very important whether the valve consists of two or three leaflets.
Lower blood sugar and increased fat burning – without negatively affecting appetite or muscle mass. These are some of the most promising effects of a new potential drug treatment for people with type 2 diabetes and obesity, according to a new study published in the journal Cell by researchers from Karolinska Institutet and Stockholm University.
A single pellet of recycled plastic can contain over 80 different chemicals. A new study with researchers from University of Gothenburg and Leipzig shows that recycled polyethylene plastic can leach chemicals into water causing impacts in the hormone systems and lipid metabolism of zebrafish larvae.
Researchers from Tokyo Metropolitan University have created a new way of telling "aged" human cells apart from younger ones using electric fields.
Although it is known that Alzheimer's disease can start up to 20 years before the first symptoms appear, the lack of knowledge about how it progresses prevents the development of effective treatments, as well as a clear diagnosis to confront this neurodegenerative disease, which origin is also unknown.
The National Heart Centre Singapore (NHCS) and Mayo Clinic have collaborated under a Memorandum of Understanding (MOU) to accelerate cardiovascular innovation and research, and to foster knowledge for future cardiovascular care worldwide.
