Electric wound care

This E-bandage could speed up wound healing

Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in rats. They report their results in ACS Nano. Chronic skin wounds…

Brain confetti - why our sense of smell declines when we get old

As mammals age, their sense of smell deteriorates. In a study published in the journal ‘Cell Reports’, an interdisciplinary research team at Helmholtz Zentrum München and the University Medical Centre Mainz investigated why this is the case. For their study, the researchers tracked the development of stem cells in the brains of mice using what are known as confetti reporters. They then…

Discharged ICU patients need careful rehabilitation

Care models that go beyond rehabilitation services and are aimed at a smooth transition from intensive to aftercare are not established in Germany. A working group around Professor Dr Christian Apfelbacher at the Institute for Epidemiology and Preventive Medicine, Regensburg University, is currently developing a concept for intensive out-patient aftercare. ‘The project is to help improve the…

Breast cancer: Pregnancy gives (delayed) protection

In general, women who have had children have a lower risk of breast cancer compared to women who have never given birth. However, new research has found that moms don’t experience this breast cancer protection until many years later and may face elevated risk for more than 20 years after their last pregnancy. Scientists at the National Institutes of Health, along with members of the…

10 simple tips to keep Christmas overindulgence at bay

Christmas cookies, mulled wine and an extensive family feast - it seems impossible not to gain weight during the holidays. But there's hope: A study by the University of Birmingham and Loughborough University has shown that regular weighing at home and simple tips to curb excess eating and drinking can prevent people from piling on the pounds at Christmas. Researchers, supported by the National…

Parents’ brains ‘sync up’ with their infant’s when they play together

When infants are playing with objects, their early attempts to pay attention to things are accompanied by bursts of high-frequency activity in their brain. But what happens when parents play together with them? New research, published in the open-access journal PLOS Biology, by Dr Sam Wass of the University of East London in collaboration with Dr Victoria Leong (Cambridge University and Nanyang…

Psoriasis: New data point to improved treatment

The Janssen Pharmaceutical Companies of Johnson & Johnson announced results from the ECLIPSE study demonstrating that Tremfya® (guselkumab) was superior to Cosentyx® (secukinumab)* in treating adults with moderate to severe plaque psoriasis for the primary endpoint assessed at week 48. Data from the multicentre, randomised, double-blind head-to-head Phase 3 study demonstrated that 84.5…

This gel could help the body after cancer surgery

Many people who are diagnosed with cancer will undergo some type of surgery to treat their disease — almost 95 percent of people with early-diagnosed breast cancer will require surgery and it’s often the first line of treatment for people with brain tumors, for example. But despite improvements in surgical techniques over the past decade, the cancer often comes back after the procedure. Now,…

Giving birth raises risk of breast cancer in younger women

Younger women who have recently had a child may have a higher risk of breast cancer than their peers of the same age who do not have children, according to a large-scale analysis co-led by a University of North Carolina Lineberger Comprehensive Cancer Center researcher. The findings, published in the Annals of Internal Medicine, may seem contrary to conventional wisdom that childbirth is…

Obesity and pregnancy: A risky couple

New research from the University of Adelaide’s Robinson Research Institute supports the need for dietary and lifestyle interventions before overweight and obese women become pregnant. The researchers have reported the results of a large study of birth outcomes in more than 500 overweight or obese women from three public maternity units in Adelaide, Australia in The Lancet Diabetes &…

Intracerebral hemorrhage

Can sudden weather change raise stroke risk?

A collaborative study led by a neurologist at Rush University Medical Center and an environmental scientist at the University of Illinois at Chicago suggests that weather patterns that cause dramatic changes in barometric pressure may increase the incidence of a type of stroke known as spontaneous intracerebral hemorrhage, that is, the rupture of a blood vessel in the brain. The researchers…

HIV and gene editing: beware of the butterfly effect, cautions expert

The claim of a chinese professor has caused quite a controversy: He Jiankui announced that he successfully modified human DNA to prevent two girls from contracting HIV. Upon the leak of this research, ethicists and scientists alike condemned Jiankui's gene editing in humans. West Virginia University Vice President and Executive Dean for Health Sciences Dr. Clay Marsh says that although “a lot…

Fibre probe explores the depth of our brain

This could be a major step towards a better understanding of the functions of deeply hidden brain compartments, such as the formation of memories, as well as related dysfunctions, including Alzheimer’s disease. Researchers from the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena and the University of Edinburgh have succeeded in using a hair-thin fibre endoscope to gain insights…

Could a ’longevity protein’ be the key to rejuvenating muscles?

One of the downsides to getting older is that skeletal muscle loses its ability to heal after injury. New research from the University of Pittsburgh implicates the so-called “longevity protein” Klotho, both as culprit and therapeutic target. The paper, published this week in Nature Communications, showed that, in young animals, Klotho expression soars after a muscle injury, whereas in old…

How working night shifts raises your risk of type 2 diabetes

Women who work intermittent night shifts and do not follow a healthy lifestyle face an especially high risk of type 2 diabetes, suggests a study published by The BMJ. The researchers found that the risk of type 2 diabetes is actually higher than simply adding the individual risks associated with unhealthy lifestyle and shift work together, indicating that combining an unhealthy lifestyle with…

Suicide: Is it in our genes?

Suicide is the 10th leading cause of death in the United States, claiming more than 44,000 people in the country every year, similar to the number of deaths caused by the opioid epidemic. Previous studies show that suicide tracks in families independent of the effects from a shared environment. Researchers at the University of Utah Health are using resources unique to the state to identify…

Brain-computer interfaces: Getting a Grasp on how we think

A world where machines can be controlled by thought alone – such is the promise of so-called brain-computer interfaces (BCI). BCIs are both hardware and software communication systems that read brain and nerve signals, convert those into electrical signals and translate human thoughts into machine commands. Developers of BCIs rely on artificial intelligence, neural network models and big data…

Hair loss? This gene might be to blame

Hypotrichosis simplex leads to progressive hair loss already in childhood. A team of researchers led by human geneticists at the University Hospital of Bonn has now deciphered a new gene that is responsible for this rare form of hair loss. Changes in the LSS gene lead to impairment of an important enzyme that has a crucial function in cholesterol metabolism. The scientists now present their…

How does the baroreceptor reflex work?

The baroreceptor reflex is a fascinating medical phenomenon. The reflex is controlled by specialized neurons that react in just a fraction of a second to keep blood pressure fairly consistent. For example, when you stand up, your blood pressure normally drops—rapidly. Yet you don't faint thanks to baroreceptors, which tell your heart rate to increase and push more blood to your brain. A new…
