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.

One in five people lack protein α-actinin-3 in their muscle fiber, shows study

Almost one in five people lack the protein α-actinin-3 in their muscle fibers. Researchers at Karolinska Institutet in Sweden now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibers, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibers.

Researchers measure baseline activity of single neurons

Our brains are complicated webs of billions of neurons, constantly transmitting information across synapses, and this communication underlies our every thought and movement.

3D microscopy sheds light on the body’s immune response to obesity

Researchers who focus on fat know that some adipose tissue is more prone to inflammation-related comorbidities than others, but the reasons why are not well understood.

Nasal antiviral blocks SARS-CoV-2 transmission in ferrets

A nasal antiviral created by researchers at Columbia University Vagelos College of Physicians and Surgeons blocked transmission of SARS-CoV-2 in ferrets, suggesting the nasal spray also may prevent infection in people exposed to the new coronavirus, including recent variants.

Timing of physical activity associated with cardiovascular health for individuals with Type 2 diabetes

Numerous studies have demonstrated the role of physical activity in improving heart health for patients with type 2 diabetes. But whether exercising at a certain time of the day promises an added health bonus for this population is still largely unknown.

Researchers identify molecular link between inflammatory signaling molecule and a main oncogene

A team of MedUni Vienna researchers led by Johannes A. Schmid at the Center for Physiology and Pharmacology, Institute of Vascular Biology and Thrombosis Research, has managed to identify a previously unknown molecular connection between an inflammatory signaling molecule and one of the main oncogenes.

Study shows that physical embodiment can occur without sense of touch

Researchers at the University of Chicago, the University of Birmingham, and Bournemouth University have uncovered evidence that physical embodiment can occur without the sense of touch, thanks to a study involving two participants who lack the ability to feel touch. The research was published on Feb. 12 in Experimental Brain Research.

Study shows how SARS-CoV-2 uses an immune system defense for replication

The immune system actually wants to fight SARS-CoV-2 with antiviral signaling molecules. But a research team from Charité and MDC has now shown how such a signaling molecule can promote the replication of the virus. The results have been published in the journal EMBO Molecular Medicine.

Study: Body produces large amounts of GDF15 hormone during extended bouts of vigorous exercise

A drug that helps us to eat less could help the more than 650 million people around the world who live with obesity.

Pre-term infants fed with B. Infantis experienced lower level of intestinal inflammation

Researchers publishing in the peer-review journal Frontiers in Pediatrics report that pre-term infants fed Bifidobacterium longum subsp. infantis (activated B. infantis EVC001) experienced significantly lower level of intestinal inflammation, 62% less diaper rash, and required 62% fewer antibiotics- all of which are critical health indicators in neonatal care.

One-size-fits-all approach to evaluating blood pressure could be detrimental to women’s health

A new study from the Smidt Heart Institute at Cedars-Sinai shows that women have a lower "normal" blood pressure range compared to men. The findings were published today in the peer-reviewed journal Circulation.

New type of surgery can help amputees better control their residual muscles

MIT researchers have invented a new type of amputation surgery that can help amputees to better control their residual muscles and sense where their "phantom limb" is in space.

New tool enables study of SARS-CoV-2 mutant spectrum by ultrasequencing

SARS-CoV-2 genome is three times larger than influenza genome. Both consist of NRA molecules that mutate when replicate.

Study describes mechanism that limits immunosupressive activity of tumor-associated macrophages

Tumor cells are able to avoid the attack of the immune system through several mechanisms. For instance, these can secrete factors that turn macrophages -cells in the immune system- into dual action agents that contribute to the tumor progress and will protect it from immune body defenses: these become, thus, the tumor-associated macrophages (TAMs).

Researchers identify protein sequences involved in SARS-CoV-2 infection

In the early days of the COVID-19 pandemic, it was established that SARS-CoV-2 infects cells by binding to the human protein ACE2, which plays a role in regulating blood pressure.

New article reviews how the circadian clock controls various aspects of homeostasis

Subconsciously, our bodies keep time for us through an ancient means - the circadian clock. A new University of California, Irvine-led article reviews how the clock controls various aspects of homeostasis, and how organs coordinate their function over the course of a day.

Researchers receive $1,894,271 grant to address new drug targets for diastolic dysfunction

After the left ventricle of the heart contracts, it must relax efficiently to prepare to refill and supply the body with blood on the next beat. An increasing number of patients -- including nearly all patients with heart failure -- suffer from impaired relaxation, which is part of a clinical syndrome known as diastolic dysfunction. Currently, treatments for impaired relaxation do not exist.
