Neuron with neurofibrillary degeneration process, senile plaque, treatments. Central nervous system neuron affected by abnormal cleavage of APP (Amyloid Precursor Protein) to form senile plaque (yellow). The tau protein normally stabilizing the microtubules of the neuron phosphorylises abnormally and forms tangles (green): neurofibrillary degeneration (NFD). Cholinergic and glutamatergic neurons. Butrycholinesterases (orange), acetylcholinesterase (yellow) and NMDA (yellow) are treatment targets.

For the following reasons, adult stem cells may eventually prove to be better for cell therapy than embryonic stem cells: their greater availability in adult tissue, the absence of immune-response rejection, their decreased disposition for tumors. Removed from the patient, stem cells can be cultured and multiplied to attain a quantity that is sufficient to treat sickness or injuries. Here, representation of adult stem cells, multipotential progenitors, and committed precursors.

Protein supply of the cell. Representation of the animal protein manufacturing process. The animal feeds on proteins which are assemblies of amino acids. After the digestion of this food, the amino acids are transported to the cells through the bloodstream. Each cell manufactures energy which it draws from some of these amino acids and new proteins under the control of its genetic program.

Immune reactions after contamination by bacteria and viruses. Most of this illustration, from left to right, shows the different immune reactions of our body after contamination, either by a bacterium or by a virus. The right-hand column explains the immune reaction triggered after vaccination. After contamination with a pathogen and infection of the body, the immune system activates differently over time. The rapid immune response usually stops the infection. The phagocytes encounter the pathogen and the phagocyte absorbs it to destroy it. If the infection persists, slower immune responses involve specific antigen lymphocytes (in red). B lymphocytes produce antibodies that neutralize antigens. Lymphocytes destroy virus-infected cells by contact. These immune reactions eliminate pathogens and stop infection. Some lymphocytes keep in mind a first contact with an antigen. This immune memory makes the immune response more effective in a second contact with the antigen. Vaccination enables

All uses except for Canadian college and university publishing - Flu, influenza, seasonal influenza virus replication. The influenza viruses attach themselves to the surface of the host cell (in orange) thanks to its receptors which recognize the virus allowing the latter to enter the host cell. The virus's RNA is transformed into mRNA which will cause the host cell to synthesize viral proteins and make viral RNA. These elements assemble on the surface of the host cell to form new viruses (newly formed virions) in large quantities that invade the host organism, especially in the respiratory epithelium and spread the disease. The symptoms are fever, cough, difficulty in breathing, decreased appetite, muscle aches. - Restriction : Canada College and University Publishing Exclusion from 05/03/2021

Menstrual cycle with fertilization. Schematic representation of the course of the menstrual cycle over 32 days with fertilization after ovulation. From top to bottom: - what happens in the ovaries, - the hormonal dosage curves, - what happens in the uterus at the level of the endometrium, - the day-by-day timeline of the first day of one cycle to the 4th of the following cycle.

Exchanges between capillaries and muscle cells. Representation of the metabolism of a muscle cell. The muscle cell uses glucose and oxygen from the blood for its own respiration and for the production of energy. Part of the blood glucose is transformed and stored in the cell to serve as a reserve (glycogen). The cell produces waste in the form of carbon dioxide (CO2) carried away by the blood.

Illustration of the principle of replication of the flu virus. The flu virus grips the surface of the host cell (orange) thanks to receptors that recognise the virus and allow it to penetrate the host cell. The virus RNA is transformed into mRNA, then the host cell will synthesise viral proteins and produce viral RNA. These elements gather on the surface of the host cell to form new viruses (newly formed virions) in large quantites that invade the organism.

Principle of gene therapies ex vivo and in vivo. Gene therapy ex vivo allies the technics of gene therapy and stem cell therapy. It is a sampling of the patient's cells, that are then corrected by gene transfer (use of a viral vector), then reimplanted (autotransplantation). Gene therapy in vivo consists in injecting directly the vector bearing the therapeutic genetics into the patient's body, without going through a transplantation of cells.

Scientists from NASA's Cassini mission suggested in a 2016 paper that the appearance of a cloud of dicyanoacetylene (C4N2) ice in Titan's stratosphere may be explained by solid-state chemistry taking place inside ice particles. The particles have an inner layer of cyanoacetylene (HC3N) ice coated with an outer layer of hydrogen cyanide (HCN) ice. Left When a photon of light penetrates the outer shell, it can interact with the HC3N, producing C3N and H. Center The C3N then reacts with HCN to yield C4N2 and H (shown at right). Another reaction that also yields C4N2 ice and H also is possible, but the researchers think it is less likely. http //photojournal.jpl.nasa.gov/catalog/PIA20715

Cell protein intake. Illustration showing the production of animal protein. The animal feeds on proteins made up of amino acids. Once the food is digested, the amino acids are carried through the blood flow to the cells. Each cell produces energy from part of these amino acids and new proteins under the control of its genetic programme.

Duplication of a retrovirus type virus. Representation of the penetration and duplication of an AIDS-type retrovirus thanks to a host cell. The virus enters the cell, its genetic code attaches itself to the cell's DNA, which obliges the latter to manufacture all the elements constituting the virus. These elements gather on the surface of the host cell to form new viruses in large quantities which invade the host organism.

The human immunodeficiency virus (HIV-I) enters the T-lymphocyte where the virus loses its outer envelop, releasing its RNA and its reverse transcriptase. The reverse transcriptase builds a complimentary DNA strand from the viral RNA template. The DNA helix is inserted into the host genome. When this is transcribed by the infected cell, the new viral RNA and proteins are produced to form new viruses that then bud from the cell membrane, thus completing the life cycle of the virus.

This is a schematic drawing of the stages of metastasis 1) attachment 2) local breakdown 3) locomotion 4) secondary tumor. This illustration explains the process of metastasis. Once metastatic cells are attached to the basement membrane (a physical barrier that seperates tissue components), they break through with the help of an enzyme called type IV collagenase. Cancer cells then move through the blood stream enabling them to spread to other parts of the body. A secondary tumor may form at anot
