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.
If building strength and muscle mass is part of your New Year's Resolution, you may want to add a new routine to your workout.
A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.
Declining blood levels of two molecules that occur naturally in the body track closely with worsening Alzheimer's disease, particularly in women.
Elderberry juice may be a potent tool for weight management and enhancing metabolic health, according to a recent Washington State University-led study.
Autoimmune diseases, where the immune system mistakenly attacks the body's own healthy cells and tissues, often have a preclinical stage before diagnosis that's characterized by mild symptoms or certain antibodies in the blood.
Diabetes has long been lumped into two categories - Type 1, which often appears in childhood, or Type 2, which is associated with obesity and typically develops later in life. But scientists have learned that not all patients with Type 2 diabetes are the same, with some patients varying in body weight, age of onset and other characteristics.
In a large-animal model study, researchers have found that heart attack recovery is aided by injection of heart muscle cell spheroids derived from human induced pluripotent stem cells, or hiPSCs, that overexpress cyclin D2 and are knocked out for human leukocyte antigen classes I and II.
A new University of Cincinnati Cancer Center study has identified a particular strand of microRNA as a promising new target for overcoming breast cancer treatment resistance and improving outcomes.
The University of Plymouth and International Osteopathic Education (IOE) have formed a new partnership that will offer first-class training to aspiring osteopaths from across the world.
An ancient brain circuit, which enables the eyes to reflexively rotate up as the body tilts down, tunes itself early in life as an animal develops, a new study finds.
University of Iowa researchers are recommending all patients be surveyed about their physical activity levels, after a new study underscores the link between physical activity and chronic disease.
A study from a Mount Royal University physiologist and his team demonstrates the key role of the kidneys in acclimatization to high altitude, and illustrates another way that Sherpas are better adapted to high altitude ascent.
Osteoporosis is a major health concern worldwide, particularly in aging populations. Despite pharmacological advancements, challenges like side effects, costs, and limited accessibility reduce adherence to treatments.
A new gene editing tool that helps cellular machinery skip parts of genes responsible for diseases has been applied to reduce the formation of amyloid-beta plaque precursors in a mouse model of Alzheimer's disease, researchers at the University of Illinois Urbana-Champaign report.
Researchers at Tel Aviv University have developed a new platform using polymeric nanoparticles to deliver drug pairs to specific cancer types, including skin cancer and breast cancer.
SCIENTISTS have developed a way of assessing the ability of red blood cells to deliver oxygen by measuring their shape. This test could improve specialist transplant and transfusion practice as well as blood banking.
A new prediction model for infected pancreatic necrosis (IPN) in patients with acute pancreatitis (AP) offers a groundbreaking approach to improving patient outcomes.
AHCC demonstrates potential in preventing liver fibrosis progression by inhibiting HSC activation and regulating key pathways involved in liver injury.
A new publication from Genes & Diseases; DOI 10.1016/j.gendis.2024.101402, discusses insights into targeting LKB1 in tumorigenesis.
New findings in mice have uncovered a crucial mechanism linking neuronal activity to mitochondrial function, researchers report, revealing a potential pathway to combat age-related cognitive decline. Mitochondria play a pivotal role in meeting the dynamic energy demands of neuronal activity, producing adenosine triphosphate (ATP) primarily via oxidative phosphorylation (OXPHOS).
