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.
In the past vitamin D was just thought to be important in regulating calcium homeostasis and bone health as vitamin D deficiency is best known for causing rickets in children and osteomalacia in adults.
In short, the detrimental effects of sitting for prolonged hours can be divided into acute, or short-term, and long-term effects.
My research lab studies several classes of systems. We are mostly interested in looking at large protein assemblies to understand their structure, dynamics and how their properties relate to their malfunction in disease.
The cornea is a transparent tissue lining the front of the eye, that is invisible tissue to the naked eye. It is a delicate tissue and disease or injury may lead to a loss of transparency or a change in the shape of the cornea, resulting in severe visual impairment.
Delirium is a terribly distressing syndrome of acute confusion. We often see it in the emergency department in older patients and in those with multiple medical problems. They may be acting strangely at home and concerned loved ones bring them to the emergency department.
There is a lot of evidence that Staphylococcus aureus (S. aureus) is involved in eczema. Eczema is now thought to be caused by a barrier dysfunction of the skin that allows external triggers to cause an overshoot of inflammation.
Detection of malignant skin alterations is currently aided by optical microscopes such as dermoscopes or optical microscopes. While the latter offers high resolution, it comes with a major disadvantage, just like any other purely microscopic method: it only provides a partial view of the skin due to the low penetration depth.
Jacopo Annese, President and CEO of the Institute for Brain and Society, a non-profit organization dedicated to democratizing neuroscience and making neuroscience tools and knowledge about the brain more available to the public, discusses his work on the Human Brain Library.
tDCS is the administration of week electrical currents through electrodes on the scalp to modulate brain activity.
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.
