Microneedle patch delivers antibiotics locally in the skin

Added: 08.11.2021 20:50 | 217 views | 0 comments

MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results show that the microneedle patch effectively reduces MRSA bacteria in the skin.

Microneedles are promising devices for painless drug delivery with minimal side effects

Added: 08.11.2021 20:50 | 208 views | 0 comments

A recent study monitors progress in the development of microneedles for immunotherapy and discusses the challenges regarding their production. Researchers suggest using microneedles for immunotherapy due to the abundance of immune cells under the skin. The aim is to vaccinate or treat different diseases, such as cancer and autoimmune disorders, with minimal invasiveness and side effects.

Scientists invent cryomicroneedles for intradermal therapeutic cell delivery

Added: 08.11.2021 20:50 | 197 views | 0 comments

Scientists recently developed a new generation of microneedles technology which allows the intradermal delivery of living cells in a minimally invasive manner. Their experiment showed that vaccination using therapeutic cells through this ground-breaking technology elicited robust immune responses against tumors in mice, paving the way for developing an easy-to-use cell therapy and other therapeutics against cancers and other diseases.

Preclinical discovery triggers wound healing, skin regeneration

Added: 08.11.2021 20:50 | 184 views | 0 comments

Difficult-to-treat, chronic wounds in preclinical models healed with normal scar-free skin after treatment with an acellular product. Derived from platelets, the purified exosomal product, known as PEP, was used to deliver healing messages into cells of preclinical animal models of ischemic wounds. The research team documented restoration of skin integrity, hair follicles, sweat glands, skin oils and normal hydration.

Scientists reveal how brain cells in Alzheimer's go awry, lose their identity

Added: 08.11.2021 20:50 | 215 views | 0 comments

Despite the prevalence of Alzheimer's, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists have uncovered new insights into what goes awry during Alzheimer's by growing neurons that resemble -- more accurately than ever before -- brain cells in older patients. And like patients themselves, the afflicted neurons appear to lose their cellular identity.

New drug molecules could prevent skin aging caused by sun exposure

Added: 08.11.2021 20:48 | 230 views | 0 comments

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.

Source of DNA mutations in melanoma

Added: 08.11.2021 20:48 | 220 views | 0 comments

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.

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.
