What do medical interventions help do?
Medical interventions help maintain health and homeostasis in the body.
What can a variety of methods do?
A variety of methods can be used to detect and/or identify infectious agents.
What is a medical intervention?
The act of intervening, interfering or interceding with the intent of modifying the outcome. In medicine, an intervention is usually undertaken to help treat or cure a condition.
Any measure whose purpose is to improve health or alter the course of a disease.
What are the main categories of the interventions that function to maintain human health?
treatments, diagnostics, and equipment
How do scientists gather evidence during the potential outbreak of an infectious disease?
-recording patients' symptoms and find similarities with other patients -isolate bacteria in a lab
go to affected areas and determine the origin
DNA sequences can be used to identify disease pathogens since they alter the DNA sequences
What is bioinformatics?
The collection, classification, storage, and analysis of biochemical and biological information using computers especially as applied in molecular genetics and genomics.
How can DNA sequences be used to identify disease pathogens?
They can find genes that are associated with the pathogen
You can compare the DNA of the pathogen with a data base of known pathogens to identify it.
What is an antibody?
An antigen-binding immunoglobulin, produced by B cells, that functions as the effector in an immune response.
How do antibodies identify and inactivate antigens?
they use shape recognition
the proteins of cells are configured to specific antibodies, so the foreign antigens bind to the specific antibodies that inactivate them
Each antibody will only bind to one specific antigen and those bound antibodies will inactivate the pathogen and recruit lymphocytes to kill the pathogen
How can the ELISA assay be used to detect disease?
Add antigen, add primary antibody, secondary antibody, add substrate, look for color change
Why is it important for doctors to know the concentration of disease antigen present in a patient's system?
The concentration tells doctors who started the infection and it can also tell them how long the patients been infected for
explains how serious the disease antigen is
the more the disease the easier it is to diagnose patients
What steps do scientists take to diagnose, treat, and prevent future spread of a disease outbreak?
-symptoms are noted -origin of pathogen is determined/incubation time -tests like blood tests to determine antibodies & antigens -preventative measure like quarantining
Antigen
A foreign macromolecule that does not belong to the host organism and elicits an immune response
Bioinformatics
The collection, classification, storage, and analysis of biochemical and biological information using computers especially as applied in molecular genetics and genomics
Concentration
The amount of a specified substance in a unit amount of another substance
ELISA (Enzyme-linked immunosorbent Assay)
A quantitative in vitro test for an antibody or antigen in which the test material is absorbed on a surface and exposed either to a complex of an enzyme linked to an anti-immunoglobulin specific for the antibody followed by reaction of the enzyme with substrate to yield a colored product corresponding to the concentration of the test material
Detects and measures antibodies in your blood
Enzyme
A protein serving as a catalyst; a chemical agent that changes the rate of reaction without being consumed by the reaction
Genome
The complement of an organism's genes; an organism's genetic material
Medical Intervention
Any measure whose purpose is to improve health or alter the course of disease
Outbreak
A sudden rise in the incidence of a disease
Pathogen
A specific causative agent of disease
Primer
A molecule (a short strand of RNA or DNA) whose presence is required for formation of another molecule (a longer chain of DNA)
Serial dilution
A stepwise dilution of a substance in solution
Solute
A substance dissolved in another substance
Solution
A homogeneous mixture of two or more substances, which may be solids, liquids, gases, or a combination of these
Solvent
A substance, usually a liquid, capable of dissolving another substance
Substrate
The reactant on which an enzyme works
ELISA Test
The sample is added to a plastic well, where the proteins are bound to the cell wall. A detergent washes away unbound proteins while preventing more proteins from binding to the cell wall.
The Primary Antibody binds to a specific antigen in the cell. Excess is washed away.
The Secondary Antibody, which is bound to the enzyme, is added. Excess is washed away.
The enzyme substrate is added, causing the liquid to turn blue (oxidation)
