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.
I'm an MR imaging scientist in the preclinical field. I'm a team leader of the functional and molecular imaging team at the National Institute of Radiological Sciences (NIRS) in QST.
It is important to keep in mind that nontuberculous mycobacteria are environmental, and so unlike mycobacterial tuberculosis, generally this is not a person to person transmitted disease. The organisms are found universally in water and soil and so most people are exposed on a daily basis.
Aging is the continuing process of such stress exposures, and with advancing age (normal aging), we must carry lots of senescent cells within our bodies. Senescent cells also often provide some ‘bad influences’ to surrounding healthy cells; such as chronic inflammation and tumorigenesis
Food allergies affect approximately 8% of school children in the United States and the United Kingdom. The highest prevalence of food allergies is in Australia affecting approximately 10% of young children. It is lower in the developing world.
Perioperative practice is quite a specialised area focused on patients who are undergoing surgery. Patients come to theatre for a reason, usually to have an operation or procedure that will correct a condition or perhaps alleviate discomfort.
Inflammatory bowel disease (IBD) is a chronic relapsing inflammation of the gastrointestinal tract with abdominal pain and diarrhea being the most common symptoms. It can be challenging to diagnose as gastrointestinal complaints mimicking IBD are common.
They undertook a modelling study based on six states in the US in areas that are at risk of Zika emergence. The main finding of this study was that the total cost of Zika in these sates had a range that went from approximately 183.4 million dollars to 1.2 billion dollars.
Schistosomiasis is a parasitic disease, sometimes called bilharzia or snail fever. The disease impacts a huge number of people around the world, over 230 million people are infected with one of the schistosome species, the parasitic worms that causes the disease.
Unfortunately, studies show that only about 5 million people living with OAB seek care from a doctor, and only half of those patients seek a specialist like a urologist or urogynecologist for treatment. It’s time to see a doctor if you’re using multiple leakage pads per day, not doing things you like because of the fear of leakage, planning all your travel around bathroom locations, or are worried about the problem every day.
Antibiotic resistance is happening in hospitals quite frequently. Probably the main place where resistant organisms and pathogens are acquired is in intensive care units (ICUs).
The mTOR pathway is probably the main pathway in humans and other animals that drives growth. That is, the accumulation of mass and adding mass to make an organism bigger by both making more cells, and making cells grow and become bigger.
Traditionally, we use biopsies to try to predict how cancer spreads. There are a number of molecular markers that are used, but biopsy is a limited approach. Now, the current trend is to use liquid biopsy, which is basically a blood sample.
If we were to compare the progression of cryopreservation technology during recent years, we would find that from 2004 to 2013 over a timeframe of a decade, there has been around a 2.5 times increase in the rate of frozen-thawed embryo transfers (FETs) that were reported to the Society for Assisted Reproductive Technology (SART). While the rate of fresh embryo transfers (ET) that were completed was the same.
Cluster headaches are probably the most painful types of pain a human can suffer and it is for no small reason that this condition is also sometimes referred to as suicide headache.
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.
