The TSC2 gene provides instructions for producing a protein called tuberin. Within cells, tuberin interacts with a protein called hamartin, which is produced from the TSC1 gene. These two proteins help control cell growth and division (proliferation) and cell size. Proteins that normally prevent cells from growing and dividing too fast or in an uncontrolled way are known as tumour suppressors. Hamartin and tuberin carry out their tumour suppressor function by interacting with and regulating a wide variety of other proteins.

Anaemia
Anaemia means that you have fewer red blood cells than normal or you have less haemoglobin than normal in each red blood cell. In either case, a reduced amount of oxygen is carried around in the bloodstream. Anaemia types and causes Iron-deficiency anaemia Lack of iron is the most common type of anaemia in the UK. This is called iron-deficiency.

Respiratory syncytial virus (RSV) vaccination
The RSV vaccine helps protect babies and older people from the common infectious disease of the airways and lungs. Here we have information about the respiratory syncytial virus (RSV) vaccine and who should get it. What is the RSV vaccine. RSV infection also causes more severe lung infections in older people, and often causes them to be admitted.

Can I take Tetracycline and Calcium together?
This is because the calcium binds to the medicine in your stomach, preventing... Why this happens This is a pharmacokinetic interaction involving absorption. Calcium is a multivalent cation that undergoes 'chelation' with tetracycline. They bind together to form an insoluble complex in the digestive tract that is too large to pass through the gut.

Can I take Reishi and Turkey tail together?
Combining them might increase the chance of thinning your blood or over-stimulating your immune system, though this is rarely a problem for healthy people. Why this happens Both reishi (Ganoderma lucidum) and turkey tail (Trametes versicolor) contain bioactive compounds called polysaccharides (like beta-glucans) that modulate the immune system..

Tourette syndrome
Tourette syndrome is a condition that causes you to make involuntary movements or noises called tics. It tends to be associated with various other problems such as behavioural problems and attention deficit hyperactivity disorder (ADHD). It can often be well managed with psychological treatments and sometimes with medication. Simple motor tics are.

Complex regional pain syndrome (CRPS)
Complex regional pain syndrome is a debilitating, painful condition in a limb, associated with nerve, skin and bone abnormalities. The condition often follows an injury to that limb. However, there is no relationship to the severity of the injury, and in some cases there is no history of any injury. It usually affects one limb, but can later.
