Myocardial infarction, coronary artery with thrombus, atheromatous plaques, treatments. The atheromatous plaques (yellow) in the wall of the coronary artery cause coronary disease. in the zoom of the coronary vessel, a thrombus forms at the bottom right, in contact with the blood by platelet aggregation. Treatments act on platelets to prevent platelet aggregation, on the secretion of aldosterone by the kidneys and adrenals, but also upstream, on the liver by limiting the synthesis of cholesterol at the origin of atheromatous plaques.

Illustration of skin tanning under the effect of the suns ultraviolet rays. Melanocytes (green cells in the epidermis) produce melanin, a pigment that absorbs ultraviolet rays. Melanin travels in melanosomes that migrate towards keratinocytes, placing themselves on their nucleus to protect their DNA and prevent genetic mutations due to the sun. Melanin makes the skin browner, thicker and more resistant to ultraviolet rays. (Photo by: BSIP/UIG via Getty Images)

Illustration of the signs of ageing in skin, dulling of the epidermis, brown spots, skin slackening and wrinkles. In the centre of the image: a cross-section illustration of young skin enabling a comparison with different types of ageing: -Top left illustrates the dulling of the epidermis, the skin is dry and cutaneous microrelief is irregular, causing the skin to become permeable to pollutants and dehydration. Superficial microcirculation is less good; skin cells become less oxygenated. -Top right illustrates spots. If they are brown it is due to melanin deposits, when red it is due to superficial microcirculation vessels, which are dilated. -Bottom left illustrates the loss of firmness due to diminished activity of the fibroblasts (blue). Fibroblasts are responsible for skins elasticity, producing elastin and collagen -Bottom right illustrates wrinkles due to the deterioration of collagen (white vertical) and elastin (pink horizontal) fibers.

The causes of eczema are : -irritants -emotional disturbance -changes in temperature or humidity -skin infections

Illustration of an IVF (In Vitro Fertilization). On the left, a classic IVF: the spermatozoa and occytes are placed in an embryo culture environment that favors their survival. Spontaneous fertilization takes place at 37° during incubation. On the right: IVF ICSI: having taken and prepared the sperm and ovules in a favorable embryo culture environment, a spermatozoon is injected into the ovules cytoplasm. After a 48-hour incubation period, the fertilized egg becomes an embryo which can be transferred to the uterus. Several embryos are be obtained, two or three of which will be transferred to the uterus. The others are frozen and transferred later if the couple so wishes.

Illustration of both types of diabetes. On the left, glucose absorption in a healthy individual : insulin (yellow) latches into an insulin receptor (green), which opens the glucose transporter (pink), and allows the cell to absorb the glucose (purple). In the middle, type 1 diabetes : insulin is not produced so cells cannot open their glucose transporters. They dont absorb the glucose, lack sugar to function and blood sugar levels increase. On the right, type 2 diabetes : cells become resistant to insulins action which is no longer recognised by insulin receptors, limiting glucose absorption which then accumulates in the blood causing hypoglycemia.

Horizontal section of a child's bone, bone structure, pediatrics. This illustration shows a horizontal section through the shaft of a long bone in children. The medullary cavity in the center is narrow. It is surrounded by resorbed bone tissue (dark beige). Then this tissue is surrounded by new bone tissue (light beige). Bone progression goes from the resorbed tissue to the outside of the bone. The bone reaches its final ossification between the ages of 18 and 25. Finally, the bone is covered on the outside by the periosteum (pinkish brown). (Photo by: JACOPIN/BSIP/UIG)
