These glands discharge into the inner anal region. An abscess in the rectum or in the perianal area can give rise to connection canals -- so called fistula -- that may reach to the skin. During surgery first the fistula will be explored with a probe to determine its course. Then it will be opened and the inflamed tissue removed. With this technique only very little of the inner sphincter musculature is sacrificed.

There the added gene will attach. Subsequently the gap in the plasmid will be sealed enzymatically. The product is a recombinant DNA, this means newly combined genetic material. It will be added to the bacteria culture. Special chemical substances enhance the intake of the new plasmid into some of the bacteria. Those will then produce and excrete insulin.

An incoming electrical impulse causes little vesicles in the synaptic knob of the neuron to discharge their content into the synaptic cleft. The released messenger substances, named neurotransmitters, exactly match the receptors of the opposite cell where they trigger an excitation. There are excitatory transmitter substances like glutamate and acetylcholine or inhibitory compounds like GABA or glycine. At a synapse information can be passed on only in one direction. On average all neurons in the brain are connected to other nerve cells through more than 10 000 synapses.

It is at the front of the neck and especially in men can be seen as the Adam's apple. The two vocal cords span the cavity of the larynx. They consist of complex muscle and tissue layers which can be adjusted in position. Air streaming from the lungs makes the vocal cords vibrate and produce the voiced tones. The more relaxed the vocal cords, the more slowly they vibrate and the pitch gets lower. If they are tenser, the vocal cords' oscillation frequency increases and the pitch gets higher.

In a laparoscopic colectomy, the surgeon uses a camera to see inside your belly and small instruments to remove the part of your large bowel. You will have 3 to 5 small cuts in your lower belly. The surgeon passes the medical instruments through these cuts. You may also have a cut of about 2 to 3 inches if your surgeon needs to put a hand inside your belly. Your belly will be filled with gas to expand it. This makes the area easier to see and work in. Your surgeon will remove the diseased part of your large bowel. The surgeon will then sew the healthy ends of the bowel back together. This is called resecting. Then your cuts will be closed with stitches.

Inside of a cell there are mainly potassium ions and organic anions, on the outside above all chloride and sodium ions. As a rule the inner part of the cell is hence negative and the outer part positive. This electric potential difference -- which is called also the resting potential of the cell -- ranges between -40 and -75 millivolts for mammalian neurons. Normally this resting potential would continuously decrease over time, as sodium ions constantly move into the cell. To prevent this and to keep the resting potential constant, these sodium ions are actively transported out of the cell. For this purpose there are transport proteins situated within the cell membrane -- the so called carriers. As these carriers are also able to actively transport potassium ions from the surroundings into the inner part of the cell, they are called the sodium-potassium-pump.

The plasmids are "disarmed" and then used to transfer a whole variety of different genes. The big advantage of this method as compared to the procedure for insulin production is that the new genetic information will be stored within the genetic material and hence passed on from cell to cell. As it is relatively easy to grow new plants out of single cells from tissue cultures, complete transgenic organisms are quite readily obtained.

The procedure is like that: smallest injuries of the vein wall call a whole armada of sealing substances into action. These so called thrombocytes clot and attach to the inner wall of the vessel and form a thrombus. This thrombus can detach and be transported with the venous blood stream to other areas of the body and organs. For example to the heart and from there further to a lung lobe. If it blocks a lung artery, the downstream network of vessels is no longer supplied with blood. This may lead to a complete loss of lung function -- to a lung embolism.

A subsequent cooling leads to attaching of the primers to the complementary sequences -- that is to the left and right of the STRs. As a next step the temperature is raised to 74°C which activates the poymerase. Its task is to add nucleotide after nucleotide to the primer according to the template DNA. Then the mixture is heated again in order to separate the newly developed double strands. The original template has been doubled now to four chains. After another recooling the primers again attach to all four of the DNA templates. The polymerase starts working again and reheating will reseparate the double strands. The primers reattach and the polymerase restarts synthesizing the region of the STR. As this procedure works as a chain reaction the technique is called PCR, "polymerase chain reaction".

Due to an initial trigger like that, factor X is intrinsically and extrinsically activated to factor Xa. Factor Xa for its part then activates factor II -- the prothrombin. As a next step the activated factor IIa -- the thrombin - develops. Thrombin can now bind to fibrin fibers and activate them, too. The activated fibrinogen is now able to crosslink with other fibrinogen molecules. At first fibrin develops, then big fibrinopeptides. Fibrinopeptides crosslink thrombocytes and erythrocytes at the vessel wall to a small thrombus. Over time more and more thrombocytes stick until a big thrombus develops. Then rapid action is required. Because the thrombus may detach and block a vessel somewhere else -- for instance in the brain.

The vestibular system consists of three semicircular canals , the utricle , and the saccule . Each of the semicircular canals lies anatomically in a different plane, each plane at a right angle to each other. Thus, each deals with different movement: up and down, side to side, and tilting from one side to the other. All contain sensory hair cells that are activated by movement of inner ear fluid . As the head moves, hair cells in the semicircular canals send nerve impulses to the brain, These nerve impulses are processed in the stem of the brain and in the brain's cerebellum. The ends of the semicircular canals connect with the utricle, and the utricle connects with the saccule. While the semicircular canals provide information about movement of the head, the sensory hair cells of the utricle and saccule provide information to the brain about head position when it is not moving.

These amino acids like alanine, leucine, valine or glutamine are connected to long, mostly even very long chains. The different sequences of amino acids within these chain-like molecules -- the biochemist speaks of the "primary structure" -- are characteristic for the different proteins. These chains are commonly folded or twisted which results in the "secondary structure". Due to specific interactions within different parts of the molecule, often a three dimensional -- tertiary -- structure of the protein is defined.

It affects the neurons that control the skeletal muscles. The highly resistant bacterial spores can be found almost everywhere. Infection takes place when the spores enter through a wound. Under anaerobic conditions the germs can proliferate within the wound and produce dangerous toxic substances. These toxins damage the neurons that are important for coordinating muscle activity. This results in a disturbed balance between muscle tension and relaxation.

This is a very efficient repairing system as it reduces mutation rate to one in a billion. Whereas the pairs are well conserved within the double helix, within the single strands another source of errors may arise: If there are frequent series of GC these can complementarily bind on the single strand and form loops that cannot be read during replication. There is another repairing system looking to this kind of errors -- which may however insert too many GC pairs. The DNA length may be minimally changed by these processes. The corrections are done within a time frame of several minutes.

The tonsils are areas of lymphoid tissue on either side of the throat. An infection of the tonsils is called tonsillitis. Most commonly, the term "tonsils" refers to the palatine tonsils that can be seen in the back of the throat. Like other organs of the lymphatic system, the tonsils act as part of the immune system to help protect against infection. In particular, they are believed to be involved in helping fight off pharyngeal and upper respiratory tract infections.

Once a certain size is reached, the follicle bursts and sets the egg cell free. This egg cell travels to the womb and there settles in the mucosa. If no fertilization takes place menstruation is triggered and the uterine mucosa shed. Sometimes it happens that a follicle keeps growing. In this case a cyst will develop. It hence arises from normal ovary function. These follicle cysts are relatively common but largely benign. Mostly they are no larger than 6 cm and resolve spontaneously in more than 90% of cases.

Benign paroxysmal positional vertigo (BPPV) usually affects one of the sensing tubes in the inner ear called the posterior semicircular canal. BPPV occurs when debris made up of calcium carbonate and protein (called otoliths or ear crystals) builds up in and moves around in the posterior semicircular canal. BPPV also can affect the anterior canal or the horizontal canal. When the head is moved in certain ways (eg, turning in bed, looking up, bending over), the calcium crystals move around and trigger inner ear sensors, causing a brief sensation of spinning. Inner ear degeneration (usually occurs in elderly patients), head trauma, and inner ear infection (eg, otitis media, labyrinthitis) can cause BPPV.

A tumor cell eliminates all genes that might stop it from growing expansively and activates all genes that are required for growth. Within the single cells the ratio of genetic material and mRNA hence changes. A fact that is used for DNA-chip technology. On the chip surface short DNA sequences are attached that are known to be normally present or transcribed in breast tissue. They are called DNA probes and work like a fishing-rod. One chip can carry up to 100.000 probes Now healthy as well as tumor tissue samples are collected. From those DNA or mRNA is isolated and fluorescence labeled. If a droplet of this solution is brought onto the chip the DNA probes will bind to the complementary DNA and mRNA strands respectively.

The first sperm to pass the membrane of the egg cell closes the entrance for all other sperms. Directly after the entry the genetic material of both gametes fuses. The chromosomes of the egg cell combine with the chromosomes of the sperm cell. The new cell -- the zygote -- starts to divide and travels through the fallopian tube down into the womb, where it nests and takes up nutrients from the uterine lining.

Due to this high mobility, however, the shoulder is particularly prone to degeneration and traumata -- especially with sports. Acromioclavicular joint arthrosis is a painful condition where the distance between the clavicle and the acromion is reduced which leads to grinding of the bones. Dislocation or luxation of the shoulder mostly leads to tearing of the stabilizing ligaments. Another common problem is calcification at a narrow point within the tendon sheet which causes an inflammatory response occurring especially at night.

It is transmitted in the form of electrical impulses. Between the single neurons there are microscopic gaps, the so called synaptic clefts. They are bordered on one side by the presynaptic membrane, on the opposite side by the postsynaptic membrane. The electrical impulses cannot cross the gap and the transmission is hence done by chemical substances, the neurotransmitters. When electrical impulses arrive at the synaptic knob, little vesicles fuse with the presynaptic membrane and release neurotransmitter into the synaptic cleft. This messenger substance now crosses the gap and binds to receptors sticking out from the postsynaptic membrane of the downstream neuron. The neurotransmitter molecules fit to the receptors like a key fits to a key hole. When they bind, ion channels open. This leads to altered membrane conductivity, the cell is depolarized and the signal transmitted.

The sense of balance is maintained by complex relationships between sense organs that are located in the ears, eyes, joints, skin, and muscles. The brain (part of the central nervous system) receives and processes the input from these peripheral sense organs. When the system is working successfully, the brain is able to tell us in what direction we are pointed, what direction we are moving toward, and if we are turning or standing still. Balance problems can occur, however, when the brain receives conflicting messages from the different sense organs, or if a disease affects one or more of the sense organs. The balance system The vestibular (balance) system is made up of five organs that are housed in the inner ear (labyrinth). These so-called vestibular organs are the three semicircular canals, the saccule, and the utricle. (The saccule and the utricle make up the vestibule.) See the Figure. The semicircular canals are responsible for the detection of rotation (angular acceleration). In contrast, the saccule and utricle are responsible for the detection of straight-line (linear) acceleration and gravity.
