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.
ALS is a neurodegenerative disease in which motor neurons in the brain and spinal cord are damaged. As ALS progresses, neurons are unable to send impulses to muscles, making voluntary muscle movement difficult, including standing, walking and sitting, as well as speaking and swallowing.
We used to sleep in two phases, with a first sleep and then a second sleep. Arguably from time immemorial to the nineteenth century, the dominant pattern of sleep in Western societies was biphasic, whereby most preindustrial households retired between 9 and 10pm, slept for 3 to 3 ½ hours during their “first sleep,”
Our main findings showed that high-performance athletes were just as likely as non-athletes to report mild or more severe depressive symptoms.
RNA sequencing is basically the isolation of RNA from cells and the use of reverse transcriptase to turn the RNA into DNA. You can then use your standard DNA sequencing technologies to quantify the cDNA that you obtained from the reverse transcription reaction.
Three in five teenagers surveyed by the British Skin Foundation reported ‘a fall in self-confidence’ as the biggest impact that acne has on their lives. From my experience as a dermatologist I find that those with acne can often feel unsupported, socially isolated and become withdrawn.
Deaths in 2015 increased by 5.6% compared to 2014, with 28,231 more deaths recorded. This is the biggest percentage increase for over 50 years, and third biggest since WWII.
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.
