PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Illustration of the whole brain in the human head. This side view shows the extensive convolutions of the cerebrum (white); with the cerebellum below it, here coloured red. At the base of the brain is the brainstem, consisting of Cand medulla, which is a thickening of the spinal cord. In the neck the cervical vertebrae have been sectioned through (spongy brown); nerves of the spinal cord can be seen which pass to the face and neck.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Appendicitis. Illustration of a human appendix, showing it red and inflamed in appendicitis. At lower right, the appendix appears as the narrow finger-shaped tube that branches off the first part of the large intestine (caecum, upper left). Inflammation of the appendix in appendicitis is a common cause of abdominal pain in children and young adults. Usually it is due to improperly digested food or a lump of faeces blocking the opening to the appendix. Symptoms include pain in the lower right-hand side of the abdomen, fever, loss of appetite and vomiting. Treatment of acute appendicitis is usually an appendic- ectomy, the surgical removal of the appendix.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Prostheses. Computer illustration of a man's body containing artificial implants (prostheses). The prostheses are (from top to bottom): skull plate, brain shunt (white tube) to drain excess cerebro- spinal fluid from the brain, cochlear implant to restore hearing, false eye, artificial jaw, artificial tooth, plastic trachea (windpipe), heart pacemaker (upper left), artificial aortic heart valve (white, above heart), arterial stent (to the right of the valve) to hold the artery open, pinned vertebral column and an inflatable penile implant. Numerous artificial joints are seen, along with a prosthetic lower leg.

PHOTO: EAST NEWS/SCIENCE PHOTO LIBRARY Heart after heart attack. Gamma scanning used to assess a 74-year-old man's heart following a heart attack (myocardial infarction). 12 coloured gamma scans (upper left) show blood uptake by the heart muscle, ranging from adequate (red) to inadequate (blue). A graph (upper right) shows the ejection fraction (EF) of the heart (the amount of blood it is pumping) to be an adequate 55%. The four models along bottom (based on gamma scanning) show four different parameters of heart function. Ischaemia (reduced blood flow) has been diagnosed for some areas of this heart. Radioactive tracers were used to label the blood and track its uptake by heart muscle by detecting its emissions of gamma rays.

PHOTO: EAST NEWS/BSIP Recherche d'un vaccin contre le sida. Repr??sentation d'une des recherches pour un vaccin contre le sida. Ce vaccin ?. ADN protA?ge les souris contre le virus. Le principe consiste ?. injecter dans un macrophage de souris des boucles d'ADN contenant les informations pour fabriquer des morceaux de virus (exemple : le harpon lui permettant de se fixer ?. la cellule h??te). Ces morceaux de virus sont pr??sent??s aux lymphocytes T CD4. Activ??s, ces lymphocytes d??clenchent la r??action immunitaire afin d'obtenir des lymphocytes T CD8 m??moires et des quelques anticorps sp??cifiques permettant de d??truire les morceaux de virus s??lectionn??s dans la boucle d'ADN. Research into an AIDS vaccine. Illustration of one type of research into an AIDS vaccine. This DNA vaccine protects mice from the virus. The method: DNA strands containing the information for producing fragments of the virus (ex. the harpoon enabling it to latch on to a host cell) are injected into a mouse microphage. These virus segments are presented to the T CD4 lymphocytes which, activated, trigger an immune response which produces memory T CD8 lymphocytes and a few specific antibodies making it possible to destroy the selected virus segments in the DNA strands.

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.
