An exercise physiology study has demonstrated that perception of core body temperature is altered by low-intensity exercise in cold environments. The findings have provided important information about the role of temperature sensation in thermoregulation and suggest that, during activities performed in the water or in the winter, the possibility of accidental hypothermia should be kept in mind.
Results from a new study reveal that targeting interferon kappa, a protein made by skin cells, may reduce the severity of psoriasis. Researchers say the findings will bring physicians one step closer to optimizing treatments for patients with the autoimmune disease.
Although some people say that baldness is the 'new sexy,' for those losing their hair, it can be distressing. An array of over-the-counter remedies are available, but most of them don't focus on the primary causes: oxidative stress and insufficient circulation. Now, researchers have designed a preliminary microneedle patch containing cerium nanoparticles to combat both problems, regrowing hair in a mouse model faster than a leading treatment.
Healthy skin has a bacterial shield to protect against germs: the microbiome. This complex assembly of microorganisms was previously believed to be difficult to decipher. A team of researchers has now succeeded in using the enzyme benzonase to identify the living bacteria in skin swabs through sequencing. Their method opens up new possibilities for diagnosis and treatment in dermatology.
Imagine if you could attach something to your skin without needing glue. A biosensor, a watch, a communications device, a fashion accessory -- the possibilities are endless. Thanks to a discovery, that time could be closer than you think.
Two new molecules that generate minute amounts of the gas hydrogen sulfide have been found to prevent skin from aging after being exposed to ultraviolet light found in sunlight. Sunburn is a major cause of premature aging in skin, and a primary risk factor for skin cancer, and other skin problems associated with aging. Now, an international research team has made inroads towards being able to reverse or delay this damage for the first time.
Researchers have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumors, the molecule could play a significant role in research of wound healing disorders.
The mutations that give rise to melanoma result from a chemical conversion in DNA fueled by sunlight -- not just a DNA copying error as previously believed, reports a new study. The findings upend long-held beliefs about the mechanisms underlying the disease, reinforce the importance of prevention efforts and offer a path forward for investigating the origins of other cancer types.
In a new study, Fralin Biomedical Research Institute at VTC scientists discovered that the alphaCT1 molecule may help repair the skin's collagen matrix by altering how scar-forming cells behave. The findings were published in the Federation of American Societies for Experimental Biology Journal.
Many people react to contact allergens, but some patients develop rashes and itching much faster than others. Previously the scientists were unable to explain why, but now researchers have outlined an entire new subgroup of allergic reactions which explains these early skin reactions. The new knowledge is vital to understanding the disease mechanisms in contact allergy.
A tingling sensation on the scalp, called paresthesia, can arise for many reasons, including nerve issues, anxiety, infections, hair loss, and skin irritation. Not all types of paresthesia are unpleasant. Learn more here.
Itchy skin, or pruritus, can affect the chest. In this article, learn about the possible causes of an itchy chest, which include skin conditions, kidney problems, and hormonal imbalances. Also, find out more about treatments and remedies for itchy skin.
A rash under the breast often results from skin irritation, an allergic reaction, or heat rash. Other causes can include viral and bacterial infections and skin disorders, such as eczema or psoriasis. Learn more about the possible causes here.
