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.
Food provides us with a variety of substances we need to maintain life. These substances are essential nutrients and are classified as macronutrients (water, protein, fats, and carbohydrates) and micronutrients (vitamins and minerals).
Before I explain the discovery, I would take a step back and explain an interesting event that takes place in the cancer cells. Normal cells follow a rapid and irreversible process to efficiently eradicate dysfunctional cells. This is a natural process by which damaged cells commit ‘suicide’. This process is known as apoptosis or programmed cell death.
Professor Strachan first proposed the hygiene hypothesis back in 1989. Reviewing the evidence, he suggested that one of the causes of the recent rapid rise in allergic diseases in children was lack of exposure to childhood infections
There's a tremendous amount known about brain circuit development. Our work was inspired by experiments that were done over 50 years ago by scientists at Harvard University, Hubel and Wiesel. They received a Nobel Prize for their work and have inspired many additional experiments over the last 50 or 60 years.
We found that the recent global economic crisis may have been associated with 260,000 additional cancer deaths in the OECD, between 2008 and 2010 alone.
Patients with head and neck cancer usually present with locally advanced disease and often require more than one type of treatment, which may include surgery, radiotherapy, and chemotherapy.
In our latest report – The Battle for Breath – the impact of lung disease in the UK, figures suggest that 1 in 5 (around 12.7 million) have been diagnosed with a lung condition in the UK. If you’re over the age of 70, this rises to 1 in 3.
Neutron crystallography allows us to determine the three-dimensional structures of biological macromolecules, such as proteins, by means of the diffraction of neutrons from the regularly spaced atoms of a crystal.
SIDS is the sudden and unexpected death of a baby, which usually occurs during sleep. The great majority of the babies are aged between about two weeks and seven or eight months.
Zoonotic diseases are diseases or infections which are naturally transmissible from animals to humans, as defined in the OIE Terrestrial Animal Health Code.
The survey showed that only 50% of women consulted a healthcare professional about their symptoms, despite the fact that many women said their symptoms were having a significant effect on their work life, social life, home life and sex life.
“IDPs” is now a widely used acronym that stands for “intrinsically disordered proteins.” It is the term generally used by the scientific community to refer to a wide variety of proteins that do not have a stable 3D structure and are instead characterized by a high extent of local mobility, disorder and many conformers that are accessible at room temperature.
Appetite, as a word, come from the Latin appetitus, meaning "desire for.” Therefore, appetite can be defined as a pleasurable sensation or the desire to eat. This sensation is coordinated by several brain areas associated with reward processing such amygdala, hippocampus, ventral pallidum, nucleus accumbens and striatum, and others.
Aortic stenosis means narrowing of the aortic valve, which is the out flow valve from the left ventricle, the pumping chamber of the heart. This is the valve which opens to allow blood to flood out of the heart and all-round the body.
The majority of the countries that are affected by the Zika virus are in the Caribbean. Many of the Caribbean Islands, including large islands such as Jamaica, Dominican Republic, Barbados and US Virgin Islands, as well as Mexico and other countries in Central and South America are affected.
The O’Neill report is a wide ranging report recognising anti-microbial resistance (AMR) as a global problem with major public health and economic significance.
I’m a biophysicist at the University of Bordeaux and I mainly work on bio-imaging methods in the cancer laboratory research facility, mostly for brain cancers.
As individuals and as populations our risks of getting diseases are determined partly genetically and partly from the environment that we live in. An important part of that environment that mediates between the outside world and the inside world of our bodies is the microbiome.
We started from theoretical inorganic to bioinorganic chemistry, so looking at metals in proteins, enzymes and so on. About 30% of all the proteins that we have are metalloproteins, so it’s a huge contribution that inorganic chemistry is providing for life.
Otosclerosis is a common cause of hearing loss, particularly amongst young adults. It normally starts in their 20s or 30s and it affects about 1 in 200 hundred people. In the UK, about 300,000 people are affected by the condition.
