Insulin Production - SA3087

Insulin production. Illustration of insulin production in a beta cell of the human pancreas. The cell is shown in section, with various organelles visible: mitochondria (which provide cells with energy) are green, and the nucleus (top right) is purple. The folded membrane below the nucleus is the endoplasmic reticulum, which divides the cell into compartments. Insulin made in the cell is packaged in secretory granules (blue balls in pink saucers). These migrate through the cell and are secreted directly into a blood capillary (bottom, containing red blood cells). Insulin is a hormone that controls blood sugar level by promoting glucose uptake in the liver and muscles.

SL5671 - S. maltophilia bacteria, TEM
Stenotrophomonas maltophilia bacteria, colored transmission electron micrograph (TEM). This aerobic Gram-negative bacterium, previously known as Pseudomonas maltophilia, can cause infections in humans and is resistant to many antibiotics. It thrives in wet and moist conditions, and mainly affects patients whose immune systems have been compromised by infection or weakness. A study published in 2008 identified this bacteria as having the capacity to rapidly develop into strains with increased drug resistance. Magnification: x16,000 when printed 10 centimeters across.

E00179 - E. coli entero-haemorrhage bacteria
E. coli entero-hemorrhage bacteria. Colored scanning electron micrograph of entero-hemorrhage Escherichia coli (EHEC) bacteria. This is a dangerous form of the benign E. coli bacteria which live in the intestine. Usually transmitted by food poisoning, it can cause life-threatening diarrhoea, intestinal bleeding, kidney failure and disturbances to blood clotting. There are no effective cures for EHEC, but there are treatments for dealing with the symptoms of infection.
