Moles stop growing when they reach a certain size due to normal interactions between cells, despite having cancer-associated gene mutations, says a new study published today in eLife.
The findings in mice could help scientists develop new ways to prevent skin cancer growth that take advantage of the normal mechanisms that control cell growth in the body.
Mutations that activate the protein made by the BRAF gene are believed to contribute to the development of skin cancer. However, recent studies have shown that these mutations do not often cause skin cancer, but instead result in the formation of completely harmless pigmented moles on the skin. In fact, 90% of moles have these cancer-linked mutations but never go on to form tumours. “Exploring why moles stop growing might lead us to a better understanding of what goes wrong in skin cancer,” says lead author Roland Ruiz-Vega, a postdoctoral researcher at
Sensors printed directly on the skin have been inching closer to commercial reality in recent years. The dream of highly sensitive sensors could have a wide array of applications, from robotics to medicine, but the field has been limited by its method of circuit printing. Currently, printing circuits directly on the skin requires a lot of heat – something the skin isn’t generally fond of.
Now, researchers believe they may have solved this problem. A team from Penn State University have developed a method of fabricating high-performance circuitry directly on skin without heat, according to a study published in ACS Applied Materials and Interfaces.
While flexible sensors already exist and have applications in future physiological monitoring, applying that technology to the skin has remained an issue for scientists. If this process is viable on a large scale, it may pave the way for the technology to help patients with various
As the field of cosmetic dermatology continues to evolve at a fast pace, UConn Health is expanding its offerings of both specialized technology and the expertise to optimize it for patients’ benefit.
“We have a wide range of devices that no one else has in the region,” says Dr. Hao Feng, one of the UConn Health dermatologists with expertise in the latest cosmetic treatments. “There are a lot of things we can do, and they’re minimally invasive to noninvasive with minimal downtime. We can really make drastic changes for people, to help not only make them look better, but also feel better at the same time.”
For example, UConn Health dermatologists can use what’s known as a “pulsed dye laser” to treat
Coty Inc. (COTY) – Get Report said on Thursday that it was expanding its division for Kylie Jenner’s skincare products, Kylie Skin, to France, Germany, the U.K. and Australia.
The direct-to-consumer Kylieskin.com websites will ensure faster delivery of products. They’ll also enable customers to shop using their local languages and currencies, avoiding additional customs fees and duties, the New York beauty-products company said in a statement.
At last check Coty shares jumped 8% to $3.60.
“The launch of the Kylie Skin international websites also reinforces Coty’s strategic commitment to strengthening the direct-to-consumer business model,” said Simona Cattaneo, president of luxury brands at Coty. “We continue to see collections sell out quickly.”
“I always wanted to bring my skincare line to more consumers around the world and this will allow for an easier shopping experience and faster delivery,” Jenner, a fashion designer and entrepreneur with a big social-media following,
Nuvoola’s Luke AI Health Screening and Protection solution
Teledyne DALSA’s Calibir GXF thermal camera is a critical component within the Nuvoola Luke AI HSP solution
WATERLOO, Ontario, Oct. 06, 2020 (GLOBE NEWSWIRE) — Teledyne DALSA, a Teledyne Technologies [NYSE:TDY] company, and global leader in digital imaging technology, is pleased to provide its new Calibir GXF thermal camera as a critical component within Nuvoola’s LUKE™ AI Health Screening and Protection (HSP) solution.
The new Calibir GXF model is optimized for elevated skin temperature detection with measurement accuracy and thermal stability better than +/-0.3°C with an external reference (as recommended by IEC80601-2-59). Like Calibir GXM models, the new GXF camera is NDAA, Section 889 compliant with IEC 80601-2-59-2017 certification pending.
Nuvoola’s LUKE™ AI Health Screening and Protection (HSP) solution is unique in using their artificial
Tests for skin treatments could be screened using flatworms rather than other animals such as rabbits, according to new research.
A team at the University of Reading and Newcastle University have found that planaria, a type of flatworm, can be used as a reliable alternative for testing topical skin products used to treat human tissues such as the eyes, nose or vagina to ensure that they are not harmful.
The paper, published in Toxicology in Vitro, shows how the use of a fluorescent dye mixed with a potential skin product is absorbed through the outer layers of skin in the planaria.
The tests are cheaper and more ethical than existing animal tests, because planaria are readily available and easily cultured in a laboratory — and don’t experience suffering. While other tests are carried out on human skin cells in a petri dish, the new screening method would provide a
A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn babe. The discovery by Washington State University researchers has implications for better skin wound treatment as well as preventing some of the aging process in skin.
In a study, published in the journal eLife on Sept. 29, the researchers identified a factor that acts like a molecular switch in the skin of baby mice that controls the formation of hair follicles as they develop during the first week of life. The switch is mostly turned off after skin forms and remains off in adult tissue. When it was activated in specialized cells in adult mice, their skin was able to heal wounds without scarring. The reformed skin even included fur and could make goose bumps, an ability that is lost in adult human scars.

Harsh environments that are inhospitable to existing technologies could now be monitored using sensors based on graphene. An intriguing form of carbon, graphene comprises layers of interconnected hexagonal rings of carbon atoms, a structure that yields unique electronic and physical properties with possibilities for many applications.
“Graphene has been projected as a miracle material for years now, but its application in harsh environmental conditions was unexplored,” says Sohail Shaikh, who has developed the new sensors, together with KAUST’s Muhammad Hussain.
“Existing sensor technologies operate in a very limited range of environmental conditions, failing or becoming unreliable if there is much deviation,” Shaikh adds.
The new robust sensor relies on changes in the electrical resistance of graphene in response to varying temperature, salinity
Scientists have developed a tool for studying the biting behaviour of common pathogen-carrying mosquitoes, according to new research published this week in eLife.
The tool, which uses an artificial blood meal and a surface that mimics human skin, will provide detailed understanding of blood feeding without using human subjects as bait. It can also fit conveniently into a backpack, allowing the study of mosquitoes in laboratory and natural environments.
Blood feeding is essential for mosquitoes to reproduce, but it is during blood feeds on human hosts that they pass on pathogens such as malaria.
“Although the initial step in obtaining a blood meal — flying towards a host — is relatively well characterised, the steps that unfold after a mosquito has landed on a host are less well understood,” explains first author Felix Hol, a researcher at Institut Pasteur and the Center for Research and Interdisciplinarity, Paris, France. “There
