PHOTO: EAST NEWS/BSIP Activation et inhibition de la douleur. Repr??sentation du circuit d'activation (?. gauche) de la douleur et de l'inhibition (?. droite). - Activation : sous l'effet de stimulus nociceptif (blessure, br??lure, inflammation), l'influx nerveux est transmis lentement par les fibres nerveuses au neurone convergent de la moelle ??piniA?re, puis au tronc c??r??bral, ?. l'hypothalamus, thalamus et cortex pour les facteurs congnitifs, directement du tronc c??r??bral au cortex pour les facteurs sensoriels. - Inhibition par stimulus sensoriel tactile au niveau de la peau qui transmet l'influx nerveux au neurone convergent de la moelle ??piniA?re plus rapidement. Ainsi l'information courcircuite celle des sensations douloureuses, et atteint le tronc c??r??bral pour se diffuser dans le cerveau. La sensation de douleur est inhib??e. Pain activation and inhibition. Illustration of the circuit of pain activation (left) and inhibition (right). - Activation: through the effects of a nociceptive stimulus (wound, burn, inflammation, etc.), a nerve impulse is slowly transmitted by the nerve fibers to the spinal wide dynamic range neurons, then to the brain stem, through the hypothalamus, thalamus and cortex, for cognitive factors, or directly to the brain stem, for sensory factors. - Inhibition by sensory tactile stimulus by the skin, which transmits the nerve impulse to the spinal wide dynamic range neurons more quickly. In this way, the information shortcircuits the pain sensations and reaches the brain stem, spreading throughout the brain. Pain is inhibited.

PHOTO: EAST NEWS/BSIP FIBROMA UTERUS ILLUSTRATION A uterine fibroma is a benign tumor frequently seen in women aged 30 to 45. It is composed of conjunctive tissue and muscle fibers. It distorts the uterine cavity, sometimes projecting out into it, while remaining attached to the wall by a pedicle.

PHOTO: EAST NEWS/BSIP FERTILIZATION DRAWING Ovulation (the releasing of an ovum by a follicle), fertilization in the tubes, producing an egg, followed by nesting of the egg in the uterus and development of the embryo. Top left, an enlargement, in vignette form, of fertilization (the merging of the egg and the spermatozon), the dividing egg (into 2, 4 and 8 cells). On the right, the vignettes represent the division of the egg into 16 cells, followed by nesting (implantation of the fertilized egg complete in the uterine mucosa) and development of the embryo. Centerpiece : an enlargement of the ovum and the spermatozoon.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Kidney dialysis machine, computer artwork. Kidney dialysis (haemodialysis) is necessary when the kidneys are unable to filter waste products from the blood naturally, so the patient's blood is fed through a dialysis machine (dialyser) which acts like an artificial kidney. The procedure takes several hours and must be repeated several times a week.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY SARS virus and chicken, computer artwork. Severe acute respiratory syndrome (SARS) is an often fatal lung disease that first appeared in China in 2002. The SARS virus is a coronavirus (spheres), with the protrusions being surface proteins that aid the infection process. Birds, such as chickens, are one of the natural reservoirs for this virus. Spread of the virus from birds to humans is one way that a new SARS epidemic outbreak might take place.

The SARS virus is a coronavirus, and here is represented as rows of 'space invaders' attacking a chicken (bottom). Birds, such as chickens, are one of the natural reservoirs for this virus. Spread of the virus from birds to humans is one way that a new SARS epidemic outbreak might take place.
