L4: non-communicable diseases Flashcards
What is the role of the white blood cells
Defence against disease/infection
What two substances does the blood transport to cells that are needed for respiration
Oxygen and glucose
If a substance turns universal indicator blue what is it
Alkali
What are the arteries that supply the heart with blood called

What is the longest bone in the body
Femur (thigh bone)
What do we call the pair that muscles work in
Antagonistic pairs
What type of joint is the knee joint
Hinge
What force stops a boat from sinking
Upthrust
Where do new medicines come from
Nature, chemicals, genetic engineering
What is a candidate in medicine
Substances that might have the potential to become a new medicine
What is the timeline and development stages for a pharmaceutical product
The stages it takes to make a new medicine
What is the drug discovery?
This is where there is 5-10 000 candidates for a new medicine
What is the preclinical testing?
This is where there is 10-20 candidates for a new medicine
What is phase 1 in the clinical trials
Where there is 5 to 10 candidates for a new medicine
What is phase 2 in the clinical trials
Where there is 2 to 5 candidates for a new medicine
What is phase 3 in the clinical trials
Where there is 1 to 2 candidates for a new medicine
What is the licensing approval
Where there is 1 medicine
How can the search for new medicines start (first step of preclinical trials)
Can start with natural chemicals like plant extracts, genes, or antibodies
What is the second step to preclinical trials
Thousands of new chemicals can be modelled by computer and made in small quantities
What is the third step to preclinical trials
Whatever the source, potential treatments are mass screened against target proteins to see if effective
What is the last step to preclinical trials
Potential treatments that show promise may then go on to be tested in animals
What steps are in the preclinical trials?
Basic research, computer modelling, In vitro, animal research, safety testing
What is in vitro
Tests that can detect disease, conditions, infections
What steps are in the clinical trials
Testing on healthy people, testing on patients, randomised clinical trials, licencing, prescription
What is efficacy
How effective the medicine is
What is toxicity
How toxic or dangerous the drug is
What is dose
The amount of drug has to be taken so drug work and have least side-effects
What is preclinical trials
Drug-testing done in lab on cells, tissues & animals
What is clinical trials
Drug trials done on healthy volunteers and patients
What is a drug trial
Testing medicine on volunteer sometimes placebo used
What is a placebo
Fake drug so it shouldn’t have an effect
What is short for non-communicable diseases
NCDs
What are non-communciable diseases also known as
Chronic diseases
