Dermatology is the branch of medicine dealing with the skin and its diseases. Dermatologists take care of diseases and cancers of the skin, scalp, hair, and nails.
A protective function against protein clumping is provided by a heat shock protein within cells.
Scientists have, for the first time, demonstrated the presence of hemoglobin—a protein primarily known for its role in binding with oxygen within red blood cells—in the epidermis, the outermost tissue layer of human skin.
It can be a relief to scratch the occasional itch, but when itch gets out of control, it can become a serious health problem. How does the body know when to stop?
The first gene mapping study on human scalp hair whorls not only demonstrates that hair whorl direction has a genetic basis but also that it is influenced by multiple genes.
According to a recent Northwestern Medicine study, hair follicle stem cells also turn rigid with age, making it harder for them to generate hair, just like people’s joints can stiffen and become more difficult for them to move around.
Some stem cells have a special capacity to mobilize among growth compartments in hair follicles; however, they get stuck with age in people. Hence, they lose their capacity to mature and retain hair color, as per new research.
Aging, or senescent cells, which stop dividing but don't die, can accumulate in the body over the years and fuel chronic inflammation that contributes to conditions such as cancer and degenerative disorders.
Two common wild plants contain extracts that inhibit the ability of the virus that causes COVID-19 to infect living cells, an Emory University study finds.
In stem cell transplants for leukemia treatment, the patient’s hematopoietic system is removed and replaced with hematopoietic cells from donors.
Notalgia paresthetica-;a nerve disorder characterized by a persistent itch in the upper back-;is a common and underdiagnosed condition worldwide.
A study of the genetics of acne has identified 29 regions of the genome that influence the condition. These genetic insights offer potential new targets for treatment. They may also help clinicians identify individuals at high risk of severe disease.
Diabetic foot ulcerations – open sores or wounds that refuse to heal – are a devastating complication affecting more than 15 percent of people with diabetes and resulting in more than 70,000 lower extremity amputations per year in the United States alone.
With around 256 million cases and more than 5 million deaths worldwide, the COVID-19 pandemic has challenged scientists and those in the medical field. Researchers are working to find effective vaccines and therapies, as well as understand the long-term effects of the infection.
Moles and melanomas are both skin tumors that come from the same cell called melanocytes. The difference is that moles are usually harmless, while melanomas are cancerous and often deadly without treatment.
Macrophages are important cells of the immune system with numerous beneficial functions. However, macrophages also aggravate common diseases.
Collagen, the main component of the skin's extracellular matrix, can cause a pathological condition if it is in excess. Applying an electric field to the skin affects collagen pathways, temporarily reducing collagen production and increasing its degradation.
More than 40,000 allogeneic hematopoietic stem cell transplants are carried out worldwide every year, mostly for patients suffering from leukemia or other diseases of the hematopoietic system.
Recent research indicates that a familiar inflammatory skin condition might arise due to inadequately regulated sex hormones.
A group of clinical experts and international scientists have revealed a novel cell type in human skin that contributes to inflammatory skin diseases like psoriasis (PSO) and atopic dermatitis (AD).
Researchers at Huntsman Cancer Institute at the University of Utah (U of U) have generated the first "atlas" of human melanocytes located throughout the body.
