Published Scientists 3D-print hair follicles in lab-grown skin (via sciencedaily.com) Original source
Scientists have 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important role in skin healing and function. When it comes to engineering human skin, hair may at first seem superfluous. However, hair follicles are quite important: They produce sweat, helping regulate body temperature, and they contain stem cells that help skin heal. The finding has potential applications in regenerative medicine and drug testing, though engineering skin grafts that grow hair are still several years away.
Published Why men, wealthy people and maritime residents are more likely to develop skin cancer (via sciencedaily.com) Original source
A new study examines why people living in Atlantic regions are more at-risk for developing melanoma than other Canadians, providing lessons on skin cancer prevention for the whole country. To find out why, the researchers compared UV exposure and behaviours among different groups in Atlantic Canada based on income, education, and gender, among other factors.
Published Why does skin get 'leathery' after too much sun? Bioengineers examine cellular breakdown (via sciencedaily.com) Original source
A study explores how ultraviolet radiation can alter the microstructure of human skin. Particularly affected is collagen, the fibrous protein that binds together tissue, tendon, cartilage and bone throughout our bodies.
Published Neural signature for borderline personality disorder identified (via sciencedaily.com) Original source
A new study of a brain region called the rostro-medial prefrontal could potentially advance diagnosis and therapies for Borderline Personality Disorder (BPD).
Published Boosting the body's anti-viral immune response may eliminate aging cells (via sciencedaily.com) Original source
Aging cells express a protein that is produced by human cytomegalovirus and is targeted by certain immune cells in the body. Harnessing the immune response to this protein could have multiple health benefits during aging.
Published Scientists see anti-aging potential in an invasive weed (via sciencedaily.com) Original source
The fruit of the cocklebur plant, which grows worldwide and is often considered a noxious weed, has antioxidant and anti-inflammatory components that could make it useful as a skin protectant, according to new research.
Published Simple laser treatments may help prevent nonmelanoma skin cancer (via sciencedaily.com) Original source
In a study of patients with a history of facial keratinocyte carcinoma, 20.9% of those treated with nonablative fractional lasers experienced a subsequent keratinocyte carcinoma, compared with 40.4% of patients who did not receive laser treatment.
Published In cells, UV-emitting nail polish dryers damage DNA and cause mutations (via sciencedaily.com) Original source
The ultraviolet nail polish drying devices used to cure gel manicures may pose more of a public health concern than previously thought. Researchers studied these ultraviolet (UV) light-emitting devices, and found that their use leads to cell death and cancer-causing mutations in human cells.
Published Scars mended using transplanted hair follicles (via sciencedaily.com)
Researchers have found that hair follicle transplants can promote scar rejuvenation by altering their architecture and genetic makeup.
Published Researchers develop painless tattoos that can be self-administered (via sciencedaily.com) Original source
Researchers have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics.
Published Researchers produce nanodiamonds capable of delivering medicinal and cosmetic remedies through the skin (via sciencedaily.com)
A novel approach provides an innovative solution to overcoming two major challenges in delivering medicinal and cosmetic remedies through the skin. Combining techniques in nanotechnology and optics, researchers produced tiny (nanometric) diamond particles so small that they are capable of penetrating skin to deliver these remedies. Next, they created a safe, laser-based optical method that quantifies nanodiamond penetration into the various layers of the skin and determines their location and concentration within body tissue in a non-invasive manner -- eliminating the need for a biopsy.
Published Microneedling beats chemical peels for acne scar treatment (via sciencedaily.com) Original source
Chemical peels are a common treatment for acne scars, but a new study finds that microneedling is significantly more effective for patients with dark skin.
Published Moms' problems linked to adolescent attachment issues (via sciencedaily.com)
Psychology research finds that moms with personality disorder symptoms impact their adolescent children who subsequently show a higher likelihood of insecure attachment which can impact their socio-emotional development and mental health.
Published Those with facial scars rate their own appearance more critically than surgeons and strangers (via sciencedaily.com) Original source
Patients who undergo facial surgery think their surgical scars look worse than surgeons and independent observers do, according to a new study.
Published New hair dyes avoid allergic reactions (via sciencedaily.com) Original source
Researchers have developed a range of permanent hair dyes that avoid the allergenic properties of traditional formulations.
Published Can we go from scarface to scarless? (via sciencedaily.com) Original source
Researchers examined skin regeneration over two years in various body parts of the adult newt, Cynops pyrrhogaster. Their wounds were very quickly healed over several days without prolonged inflammation. Because of this rapid healing, granulation/dermal fibrosis, and therefore scarring, did not occur. The skin was able to fully regenerate. These findings provide evidence that this newt species may be an ideal model system to study and prevent scar formation in human skin.
Published New drug molecules could prevent skin aging caused by sun exposure (via sciencedaily.com)
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.
Published Internal compression stocking helps against varicose veins (via sciencedaily.com) Original source
A new study finds that rather than destroying or removing defective veins, it is possible to repair them by using a sheath. They are thus saved for later use as a bypass.
Published 3D 'bioprinting' used to create nose cartilage (via sciencedaily.com) Original source
A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.
Published Childhood cognitive problems could lead to mental health issues in later life (via sciencedaily.com)
Children experiencing cognitive problems such as low attention, poor memory or lack of inhibition may later suffer mental health issues as teenagers and young adults, a new study reveals.
