As well as using eye drops, dry eyes can be helped by taking a supplement of omega 3,6 and 9. Sjogrenâs syndrome: An auto-immune condition affecting around half a million people in the UK, this causes the body to attack its own moisture-producing glands, leading to abnormal dryness of the eyes, says Mr Allamby.
The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (Figure 9.1).
There are two main types of endoplasmic reticulum - the rough endoplasmic reticulum and the smooth endoplasmic reticulum and both have different jobs to do. Other general functions of the endoplasmic reticulum include drug metabolism, storage of glycogen, facilitating the transport of proteins and protein folding.
