Researchers at the University of Arizona College of Medicine – Phoenix are cross-utilizing plant biology, medicine and engineering to create a novel platform. They have developed a revolutionary "lung on a leaf" to study pulmonary diseases.
Another piece in the puzzle that is non-alcoholic fatty liver disease has been solved by a University of Queensland researcher in a step towards developing treatments for a disease that affects about one in every five Australians. PhD student Laurence Britton has discovered a pivotal mechanism by which iron is able to make the liver more vulnerable to the injury and metabolic dysfunction that…
Australia's national science agency CSIRO has identified a new gene that plays a critical role in regulating the body's immune response to infection and disease.
A team of neurobiologists has identified a novel neuronal circuit in the midbrain that gates fear learning. They think that associative learning of fear is mediated by a novel dopamine circui.
Canadian researchers have found a promising way to stop tumour cells from multiplying. In disrupting the composition of ribosomes, the team from Université de Montréal (UdeM) discovered a direct molecular mechanism to stop cancer cells from proliferating, which is called senescence. Their results have been published in Nature Cell Biology. “Ribosomes are complex machines composed of both…
LC/MS, i.e. the combination of liquid chromatography (LC) with mass spectrometry (MS) – an analytical method developed primarily for environmental analysis and live science – remains a keen topic in the medical laboratory. In recent European Hospital issues, we have outlined various reasons why this procedure is in increasingly popular in the medical lab. Here we continue with an interview…
Every cell and every organism ages sooner or later. But why is this so? Scientists at the German Cancer Research Center in Heidelberg have now discovered for the first time a protein that represents a central switching point in the aging process. It controls the life span of an individual - from the fly to the human being. This opens up new possibilities for developing therapies against…
An anxious person will avoid risks whenever possible. This in itself is not exactly a surprise. However, researchers have found a way to visualize this process in the brain - with interesting implications for behaviour prediction. A team of psychologists from the German Friedrich Schiller University Jena, together with partners from Würzburg, Germany and Victoria, Canada they conducted an…
Being left-handed apparently means a lot more than gripping things differently than most, researchers find. This sheds a new light on mental health treatment, because current therapies for the most common mental health problems could be ineffective or even detrimental to about 50 percent of the population. For more than 40 years, hundreds of studies suggest that each hemisphere of the brain is…
Early whole genome sequencing might bring hope for children who are born severely ill or who develop serious illness in the first few weeks of their life. Because these children are often difficult to diagnose, detection of diseases has considerable implications for their short and longer-term care. At the annual conference of the European Society of Human Genetics (ESHG) in Milan, Italy, the…
Biomedical engineers at Columbia Engineering have discovered a new fundamental feature of brain oscillations: they actually move rhythmically across the brain, reflecting patterns of neuronal activity that propagate across the cortex. The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain,…
Dr. Thomas Hainmüller and Prof. Dr. Marlene Bartos of the Institute of Physiology of the University of Freiburg have established a new model to explain how the brain stores memories of tangible events. The model is based on an experiment that involved mice seeking a place where they received rewards in a virtual environment.
Recently, scientists have explored another version of embolization, called gas embolotherapy. During this process, the blood supply is cut off using acoustic droplet vaporization (ADV), which uses microscopic gas bubbles induced by exposure to ultrasonic waves. A team of researchers from China and France has discovered that these bubbles could also be used as potential drug delivery systems.
T cells fight pathogens and tumors: Researchers from the Universities of Tübingen and Lübeck present a simple and fast method to rapidly assess their function. Due to its simplicity, reliability and versatility, it could be broadly implemented for basic research and in the clinical setting. Methods so far to test T-cell response were technically cumbersome and time-consuming and therefore only…
A new SLAS Discovery original research article available now for free ahead-of-print, researchers from the Genomics Institute of the Novartis Research Foundation (GNF) highlights a diversity of approaches that their automated high-throughput flow cytometry has enabled for phenotypic drug discovery. Flow cytometry is a very powerful tool that has been used for decades and allows for…
Menarini Silicon Biosystems announced that a new study has found that using circulating tumor cells (CTCs), a form of liquid biopsy, holds promise as a key tool for developing a staging system that can have a significant impact in the treatment of metastatic breast cancer (MBC). In this study, the largest CTCs pooled analysis study to date, researchers determined that the CTC count could be used…
Researchers have shown for the first time that a form of artificial intelligence or machine learning known as a deep learning convolutional neural network (CNN) is better than experienced dermatologists at detecting skin cancer. In a study published in the leading cancer journal Annals of Oncology, researchers in Germany, the USA and France trained a CNN to identify skin cancer by showing it more…
Clinical trial enrolment favours men, according to a study presented at Heart Failure 2018 and the World Congress on Acute Heart Failure, a European Society of Cardiology congress.1 The study found that fewer women meet eligibility criteria for trials of heart failure medication. Helena Norberg, author of the study, junior lecturer and PhD student, Umeå University, Sweden, said: “One of the…
When was the last time you watched a Michael Jackson music video? If your answer is “never” or “not for quite a while,” you are really missing a treat. According to Rolling Stone, “No single artist … shaped, innovated or defined the medium of ‘music video’ more than Michael Jackson.” Back in the 1980s and early 1990s, MTV had only one format—music videos—and that genre…
Triggers of acute heart failure vary globally, according to late breaking results from the REPORT-HF registry presented at Heart Failure 2018 and the World Congress on Acute Heart Failure, a European Society of Cardiology congress. REPORT-HF is a global, prospective registry comparing regional differences in causes of acute heart failure, therapies, time to treatment, and outcomes. Professor Sean…
Blood is the juice of life, as while circulating through the body it delivers vital substances such as oxygen and nutrients to cells and tissues. Chemotherapy, radiotherapy and blood loss in general impoverish the system. A special kind of cells in the bone marrow, called hematopoietic stem cells (HSCs) is able to replenish the impoverished system by giving rise not only to red blood cells, but…
Aging is a major risk factor for physical frailty and the development of age-related diseases such as cancer, cardiovascular diseases, type II diabetes and Alzheimer's disease. Numerous studies have already shown that a calorie-restricted diet can significantly delay age-related conditions in several organisms like flies, worms, fish and mice, and that it even improves fitness at old age. But who…
Antimicrobial resistance is on the rise worldwide. This is becoming a problem for infectious diseases like tuberculosis as there are only a few active substances available to combat such diseases. Pharmacists at Martin Luther University Halle-Wittenberg (MLU) have now found a way to increase the efficacy of a common tuberculosis agent while, at the same time, reducing resistance to it. The…
Social media often features celebrities drinking cocktails, boozy how-to posts, and party pictures. This is the environment American teens are immersed in every day, with 71 percent of teens using more than one social media site, spending an average of nine hours a day using media. Despite the popularity of social media and alcohol-filled posts, little is known about the influence social media…
People who consume an egg a day could significantly reduce their risk of cardiovascular diseases compared with eating no eggs, suggests a study carried out in China, published in the journal Heart. Cardiovascular disease (CVD) is the leading cause of death and disability worldwide, including China, mostly due to ischaemic heart disease and stroke (including both haemorrhagic and ischaemic…
