Scientists discover origin of cell mask that hides stomach cancer

A layer of cells that look like normal stomach lining on top of sites of stomach cancer can make it difficult to spot after removal of a Helicobacter pylori infection. In a recent study, researchers from Hiroshima University have uncovered the origin of this layer of cells: it is produced by the cancer tissue itself. Helicobacter pylori (H. pylori) is a type of bacteria that lives in people’s stomachs. To survive the harsh environment these bacteria can neutralize stomach acid. H. pylori is the leading cause of stomach cancer, one of the most common types of cancer which can have a low survival rate. The bacteria cause inflammation by injecting… Read more

3D printed prosthetic hand can guess how you play Rock, Paper, Scissors

A new 3D-printed prosthetic hand can learn the wearers’ movement patterns to help amputee patients perform daily tasks, reports a study published this week in Science Robotics. Losing a limb, either through illness or accident, can present emotional and physical challenges for an amputee, damaging their quality of life. Prosthetic limbs can be very useful but are often expensive and difficult to use. The Biological Systems Engineering Lab at Hiroshima University has developed a new 3D printed prosthetic hand combined with a computer interface, which is their cheapest, lightest model that is more reactive to motion intent than before. Previous generations of their prosthetic hands have been made of metal,… Read more

Vest helps athletes keep their cool

A new cooling vest for sports athletes may ensure everyone can compete safely in sweltering summer conditions such as the upcoming 2020 Summer Olympics, reports a new paper published in Frontiers in Physiology. Strategies to cope with body heat in sports is a pressing issue. The Tokyo Olympics will be held in the hot and muggy Japanese summer where the ambient temperature is expected to be above 33°C. Athletes have to worry about performing under pressure of the high-stakes competition but also now have to deal with a very hot and humid climate. The 2022 FIFA World Cup in Qatar will also have high temperatures and athletes must use cooling… Read more

Family dynamics: molecules from the same family have different effects in cancer prognosis

Scientists observe that one molecule increases liposarcoma tumor cell spread and aggression while another molecule from the same family decreases migration and cell proliferation. Researchers at Hiroshima University have found that different levels of two molecules of the same family—TIMP-1 and TIMP-4—can influence prognosis of liposarcoma. High levels of TIMP-1 lead to a poor prognosis while high TIMP-4 indicates a less severe form of liposarcoma. This study, published in Carcinogenesis 10th May, described the molecules’ mechanism of action through the YAP/TAZ pathway. Further research can lead to new treatments and better methods of diagnosis for liposarcoma. Different types of cancer have different prognoses (medical outcomes) and some are easier to… Read more

Being too harsh on yourself could lead to OCD and anxiety

A correlation was found between strong feelings of responsibility and likelihood of developing OCD or GAD in American university students  A new study has found that people who reported intense feelings of responsibility were susceptible to developing Obsessive Compulsive Disorder (OCD) or Generalized Anxiety Disorder (GAD) was published in the International Journal of Cognitive Therapy. “People with OCD [are] tortured by repeatedly occurring negative thinking and they take some strategy to prevent it… GAD is a very pervasive type of anxiety. [Patients] worry about everything.” describes Associate Professor Yoshinori Sugiura of the University of Hiroshima. Anxiety and OCD-like behaviors, such as checking if the door is locked, are common in… Read more

This oral appliance could help you (and your partner) sleep better

An original design for an oral appliance developed in Hiroshima University Hospital can help sufferers of sleep apnea sleep more soundly   Researchers measured a novel treatment for sleep apnea developed at Hiroshima University Hospital with positive results. By measuring patients lying down flat, the researchers stimulated sleep conditions and measured the patient’s airways using 3D imaging. The study confirmed that the treatment is effective at opening the airways and warrants further collaboration between dentists and doctors in treatment of sleep apnea. Obstructive sleep apnea is a condition that causes throat muscles to relax and narrows the airways of those affected while they are asleep. Snorting, choking or gasping while… Read more
