Heartbeat secrets unlocked as cardiac rhythm gene role identified

Almost half of people testing positive for coronavirus have reported symptoms of depression, according to a new study published in the International Journal of Environmental Research and Public Health. Researchers from Bangladesh, the United States and Anglia Ruskin University (ARU) in the UK carried out a cross-sectional survey of more than 1,000 Bangladeshi adult coronavirus patients over the course of one month. A total of 48% of respondents were categorised as having moderate to severe depression, with a higher prevalence in those with persistent symptoms, low family income ...

Brain tumours are the most common solid tumours in childhood and the largest cause of death from cancer in this age group Being able to classify a brain tumour's type, without the use of biopsy, is hard to do; however diffusion weighted imaging, an advanced imaging technique, when combined with machine learning, can help a UK-based multi-centre study, including WMG, University of Warwick has found. Being able to characterise the tumour(s) faster and more accurately means they can be treated more efficiently Diffusion weighted imaging and machine learning can successfully classify the diagnosis and characteristics of common types of paediatric brain tumours a UK-based multi-centre study, including WMG at the University of Warwick ...

Researchers from North Carolina State University, Boston University and Kraton Corporation have demonstrated a family of self-sterilizing polymers that are effective at inactivating coronaviruses, including SARS-CoV-2 - the virus that causes COVID-19. The work opens the door to a suite of applications that could help to reduce the transmission of COVID-19 and other diseases. "Our work here provides conclusive evidence that these materials, anionic polymers, can inactivate human coronaviruses quickly and efficiently," says Richard Spontak, co-author of a paper on the work accepted for publication in Advanced Science. Spontak is a Distinguished Professor of Chemical and Biomolecular Engineering and ...

A team of soil scientists developed a new approach to the automatic generation and updating of soil maps. Having applied machine learning technologies to a set of rules traditionally used by experts in manual mapping, the team obtained a highly accurate model that provides easy-to-interpret results. The study was published in ISPRS International Journal of Geo-Information. Many software solutions for digital soil mapping are based on statistical models. The accuracy of such programs is limited because statistical models depend on the quality and quantity of field data and can ignore local irregularities in soil properties. It is difficult to obtain accurate and useful information from ...

TAMPA, Fla. - One of the most challenging issues in cancer therapy is the development of drug resistance and subsequent disease progression. In a new article featured on this month's cover of Cancer Research, Moffitt Cancer Center researchers, in collaboration with Oxford University, report results from their study using mathematical modeling to show that cell turnover impacts drug resistance and is an important factor that governs the success of adaptive therapy. Cancer treatment options have increased substantially over the past few decades; however, many patients eventually develop drug resistance. Physicians strive to overcome resistance by either trying to target cancer cells through an alternative approach or targeting the resistance mechanism itself, but success with ...

Oncotarget recently published "Targeting an engineered cytokine with interleukin-2 and interleukin-15 activity to the neovasculature of solid tumors" by Mortensen, et al. which reported that there is a growing interest in the antibody-based delivery of cytokines to the tumor environment as a means to boost the anti-cancer activity of tumor-resident T cells and NK cells. Here, the authors described the expression and characterization of fusion proteins, featuring the L19 antibody and an engineered cytokine with interleukin-2 and interleukin-15 ...

Oncotarget recently published "AKT isoforms have discrete expression in triple negative breast cancers and roles in cisplatin sensitivity" which reported that the authors investigated the expression and net effect of the individual isoforms in triple negative breast cancers and response to cisplatin treatment using cellular, mice models and clinical samples. Interestingly, analysis of the expressions of AKT isoforms in clinical samples showed relatively higher expression of AKT1 in primary tissues; whereas lung and liver metastatic samples showed elevated ...

Coffee, cola or an energy drink: caffeine is the world's most widely consumed psychoactive substance. Researchers from the University of Basel have now shown in a study that regular caffeine intake can change the gray matter of the brain. However, the effect appears to be temporary. No question - caffeine helps most of us to feel more alert. However, it can disrupt our sleep if consumed in the evening. Sleep deprivation can in turn affect the gray matter of the brain, as previous studies have shown. So can regular caffeine consumption affect brain structure due to poor sleep? A research team led by Dr. Carolin Reichert and Professor Christian Cajochen of the University of Basel ...

Here is a link to watch a video interview with Dr. Beatrice Aramini about this topic on the Oncotarget YouTube Channel Oncotarget published "Cancer stem cells and macrophages: molecular connections and future perspectives against cancer" which reported that Cancer stem cells have been considered the key drivers of cancer initiation and progression due to their unlimited self-renewal capacity and their ability to induce tumor formation. Macrophages, particularly tumor-associated macrophages, establish a tumor microenvironment to protect and induce CSCs development and dissemination. Many studies in the past decade have been performed to understand the molecular ...

For the first time, physicists from the University of Basel have produced a graphene compound consisting of carbon atoms and a small number of nitrogen atoms in a regular grid of hexagons and triangles. This honeycomb-structured "kagome lattice" behaves as a semiconductor and may also have unusual electrical properties. In the future, it could potentially be used in electronic sensors or quantum computers. Researchers around the world are searching for new synthetic materials with special properties such as superconductivity -- that is, the conduction of electric current without resistance. These new substances are an important step in the development ...
