News Medical's "Thought Leaders" series is a selection of articles written by national and international experts and trusted advisers in health and medicine. All the articles are written by experts who have been invited as recognised leaders in their fields to provide a "state of the art" contribution.
Very common – most of us will experience bowel symptoms from time to time, but usually the symptoms last only a few days. You should see your GP if they persist for more than three weeks (sooner if they are severe) or if your symptoms keep coming back.
Brown fat is a tissue well studied in small mammals, where it acts as a heat-producing organ to stay warm in a cold environment. Its unequivocal identification in adult, healthy humans about a decade ago is of major importance due to its immense capacity to convert chemical energy into heat
Our group describes a new entity, which we refer to as “Developmental Split-Brain syndrome” which we discovered affected four individuals from three unrelated families. All affected individuals showed disruption of communicating tracts between the right and left side of the brain which meant that there is lack of coordination and communication between the two sides of the brain.
Many of the most fundamental, life governing biological processes take place at size and time scales that remain invisible with current imaging technologies. Understanding how the molecules that underlie these processes move, interact and change could pave the way for new treatments, cures and the development of novel drug therapies.
There's no solid evidence that we sleep fewer hours today than we ever did, this is something I have gone into large amounts of detail in my book, in my published papers and at a recent meeting at the Royal Society of Medicine.
The pharmaceuticalisation of sleep, put simply, refers to the ways in which sleep becomes a site for manipulation or augmentation through pharmaceutical use. There are different ways in which sleep can be pharmaceuticalised – for example we can use pharmaceuticals to induce sleep, to consolidate broken sleep, or to prevent or delay sleep.
Colorectal cancer is a combined term to describe the malignant tumors that occur in the large intestine; the colon being the upper part of the large intestine and the rectum being the lowest part of the large intestine.
The study carried out by the Complutense University of Madrid (Spain) –UCM – is the first to evaluate retinal damage using tablets with LED screens available in the market with living animals.
Phase-contrast X-ray imaging differs from conventional X-rays because it uses a different physical principle.
Women who have surgery for their prolapse have a 3 in 10 chance of needing at least one more operation, so the success rate is not great. Gynecologists hoped that using non-absorbable synthetic mesh or biological graft material as a patch to reinforce their standard repairs, the success rate would get better.
Latest research suggests that 1 in 10 dads will suffer from postnatal depression (PND), and as many as 1 in 7 women will be diagnosed. This was from a survey by NCT released in 2015. This also revealed that as many as 38% of new dads have concerns surrounding their mental health.
Hyperglycemia occurs when a patient has higher than normal blood sugar levels. If the levels are very high, consistently 13-14 or above, the patient will start to feel tired, thirsty and feel the urge to go to the toilet frequently to pass urine (micturition).
Dance psychology is the study of dance and dancers from a scientific and psychological perspective. What we're trying to understand is what happens when people dance and why, we are looking at it from a healthcare perspective, which might suggest dancing is good for you.
The kind of research I'm interested in is a technique called diffusion MRI and this technique is sensitive to the microstructure of the tissue. Particular clinical applications that it is used for are cancer and looking at neurodegenerative diseases.
Optogenetics is a way of introducing information into the brain using light, it targets specific cells or connections across the brain. It is fast, like brain signaling, and helps you communicate with neural circuitry in a language more similar to what is normally used within the brain.
Spherical nucleic acids are structures that are made by taking a nanoparticle template and using chemistry to arrange short strands of DNA or RNA on the surface of those particles. The spherical core of the nanoparticle creates a spherical arrangement of DNA or RNA, similar to tiny little balls of nucleic acids.
Over the past couple of decades, the analytical technology and the clinical microbiology insight needed to create a breath test for infections has seen a considerable number of advances and there are now numerous research teams focused on evaluating patient breath as a diagnostic fluid for infectious diseases. Significant challenges still need to be overcome.
The human exposome is probably best defined as “everything that is not the genome.” This is a bit tongue in cheek, but basically, the exposome is comprised of all of the chemicals in your body from the environment, food, consumer products, their metabolites, the endogenous “housekeeping” chemicals, the cellular wastes from energy production, as well as all of the messenger compounds and life supporting chemicals.
The listening tactic that we investigated is the idea that if you turn your head away from the person that you're talking to, rather than directly facing them, that it would help you to understand what they're saying a little better. At the same time as still looking at them, of course, because you need to be able to lip read.
I’m an Assistant Professor at the Department of Biochemistry and Molecular Biology of the Complutense University, Madrid. Until five years ago I had been working here at the university, part time with a private clinic, where I worked in MRI and MR spectroscopy for clinical applications.
