Published Innovative paper-like, battery-free, AI-enabled sensor for holistic wound monitoring (via sciencedaily.com) Original source
Scientists have invented a paper-like, battery-free, AI-enabled sensor patch -- PETAL -- for convenient and effective monitoring of wound recovery. This novel technology provides early warning of complications to improve wound care. The paper-like, battery-free PETAL sensor patch uses five colorimetric sensors to measure biomarkers in the wound within 15 mins. A proprietary AI algorithm quickly analyses the digital image of the sensor patch to determine wound healing status with an accuracy rate of 97%.
Published Research challenges current thinking on the genetic causes of very early menopause (via sciencedaily.com) Original source
The genetic causes of very early menopause will have to be reconsidered after researchers found that nearly all women who carried variations thought to cause the condition in fact had their menopause at an older age.
Published Study hints at how cancer immunotherapy can be safer (via sciencedaily.com) Original source
Cancer immunotherapy has revolutionized treatment of many forms of cancer by unleashing the immune system response against tumors. Immunotherapies that block checkpoint receptors like PD-1, proteins that limit the capacity of T cells to attack tumors, have become the choice for the treatment of numerous types of solid cancer. However, the introduction of PD-1-blocking agents can often result in T cells attacking healthy tissues in addition to cancer cells, causing severe, sometimes life-threatening, side effects that can blunt the benefits of immunotherapy. A new study reveals new insights into how PD-1 functions to maintain healthy tissues, findings that can help scientists predict, treat, or even prevent the side effects of PD-1 blocking immunotherapies.
Published One in five women become pregnant naturally after having a baby conceived with IVF (via sciencedaily.com) Original source
New research analyzed data from 11 studies of over 5,000 women around the world between 1980 and 2021, to evaluate how common it is to get pregnant naturally after having a baby conceived by fertility treatment. Around 20% of women who needed fertility treatment, such as IVF, to conceive their first child are likely to get pregnant naturally in the future, finds a new study.
Published New diagnostic finds intact sperm in infertile men (via sciencedaily.com) Original source
Researchers develop new diagnostic tool to visualize protein biomarkers of well-developed sperm to determine if surgical sperm extraction may be successful for certain infertile men.
Published Elimination of type of bacteria suggests treatment for endometriosis (via sciencedaily.com) Original source
A research group has discovered that using an antibiotic to target Fusobacterium, a common bacterium that causes inflammation, improved the symptoms of endometriosis. Their findings suggest an alternative treatment for the disease.
Published The IL-17 protein plays a key role in skin aging (via sciencedaily.com) Original source
A team of scientists has discovered that IL-17 protein plays a central role in skin aging. The study highlights an IL-17-mediated ageing process to an inflammatory state.
Published PAINTing a wound-healing ink into cuts with a 3D-printing pen (via sciencedaily.com) Original source
The body is pretty good at healing itself, though more severe wounds can require bandages or stitches. But researchers have now developed a wound-healing ink that can actively encourage the body to heal by exposing the cut to immune-system vesicles. The ink can be spread into a cut of any shape using a 3D-printing pen, and in mice, the technology nearly completely repaired wounds in just 12 days.
Published New type of drug candidate effectively accelerates wound healing in clinical study (via sciencedaily.com) Original source
Complicated, hard-to-heal wounds are a growing medical problem and there are currently only two drugs approved with proven efficacy. In a new study on humans, researchers show that treatment with a specific type of modified lactic acid bacteria works well and has a positive effect on the healing of wounds.
Published Researchers successfully induce primate oocytes in the lab (via sciencedaily.com) Original source
The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.
Published One step closer to developing a potentially ultraprotective sunscreen from our own melanin (via sciencedaily.com) Original source
Researchers have announced a major advance in understanding the fundamental structure of melanin and one of its components that turns light into heat, protecting the body from sun damage.
Published Non-antibiotic treatment for women with persistent acne shown to be effective (via sciencedaily.com) Original source
A team of researchers has shown that a cheap and readily available drug, used to treat high blood pressure, could help the thousands of women who suffer from persistent acne.
Published Happy worms have healthy eggs (via sciencedaily.com) Original source
Researchers have exposed roundworms (a well-established model organism in biological research) to selective serotonin reuptake inhibitors (SSRIs), a class of drugs used for treating depression and anxiety. Surprisingly, this treatment improved the quality of aging females' egg cells.
Published Scientists discover the dynamics of an 'extra' chromosome in fruit flies (via sciencedaily.com) Original source
Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans and is associated with treatment-resistant cancer and infertility. The findings may one day lead to developing more targeted therapies for treating these conditions.
Published Researchers reveal an ancient mechanism for wound repair (via sciencedaily.com) Original source
The study is the first to identify a damage response pathway that is distinct from but parallel to the classical pathway triggered by pathogens.
Published Wearable patch can painlessly deliver drugs through the skin (via sciencedaily.com) Original source
A wearable patch applies painless ultrasonic waves to the skin, creating tiny channels that drugs can pass through.
Published Diet high in fruit and vegetables linked to lower miscarriage risk (via sciencedaily.com) Original source
A preconception and early-pregnancy diet that contains lots of fruit, vegetables, seafood, dairy, eggs and grain may be associated with reducing risk of miscarriage, a new review of research suggests.
Published The wound dressing that can reveal infection (via sciencedaily.com) Original source
A nanocellulose wound dressing that can reveal early signs of infection without interfering with the healing process has been developed.
Published Now you can be comfortable in your e-skin (via sciencedaily.com) Original source
Researchers have designed a cellulose nanofiber paper (nanopaper) that can be used as a substrate for on-skin electronics. The porous structure of the nanopaper means that it can conform and adhere to the skin well enough for effective signal transfer and allows moisture to pass through for breathability and comfort. It is hoped that the nanopaper can soon be used to acquire electrophysiological data, such as ECGs in the clinic.
Published How electricity can heal wounds three times as fast (via sciencedaily.com) Original source
Chronic wounds are a major health problem for diabetic patients and the elderly -- in extreme cases they can even lead to amputation. Using electric stimulation, researchers have developed a method that speeds up the healing process, making wounds heal three times faster.
