The researcher said

that not everyone has an equal chance of getting heart attacks, and not everyone

gets atherosclerosis due to diet. This could also happen due to genetic

disorders. For instance, a person can eat fatty food and still be in perfect

health. But another person consuming the same level of fatty food could be very

susceptible to cardiac attacks. Familial Hypercholesterolemia (FH) is an

inherited genetic disorder that causes dangerously high levels of LDL or bad

cholesterol. FH is one of the most common genetic disorders that affect the

heart and blood vessels, affecting 1 in 250 people. By understanding the

underlying molecular mechanisms, we can treat this disorder.

Practice question: Which

of the following statements about FH is correct?

The

students understand the importance of this knowledge in the context of the

human health. They still had questions though: “But beyond changing our

lifestyle, how does learning these things help us actually do something about

it. Can we engineer solutions for this and apply it somehow?”

The

researcher said that is for instance what he does. He uses his fundamental

knowledge about biomolecules, cells and molecular biology to help save human

lives. And he doesn’t need to be a doctor or a medical person to do this. He is

a biological systems engineer, and he specializes on nanotheranostics to help

achieve this.

Practice

question: The research fellow believes that only doctors or medical

professional can contribute to solutions in human health?

A 30-year-old patient underwent a biopsy of the

submandibular salivary gland in the ENT department due to significant swelling

of unclear origin. This eventually proves to be histologically normal. What is

this sample most likely to look like?

A 17-year-old female patient has gradually developed symptoms such as fatigue, weakness, dyspnea on exertion and impaired

performance over several months. These symptoms gradually worsen over the last

year or so. She now comes for intense right hip pain. On further questioning,

she indicates frequent epistaxis (nosebleeds) and easy development of bruises.

During the physical examination, the physician notes striking pallor of the

skin and mucous membranes, tachycardia as well as hepatomegaly (enlargement of the

liver) and splenomegaly (enlargement of the spleen). Laboratory findings

confirm the presence of anemia and thrombocytopenia. A special finding is the

picture of the so-called Erlenmeyer flask deformity of the diaphyses of the

femurs. This sign is already suggestive to the physicians and the determination

of low activity of the enzyme β-glucocerebrosidase in isolated leukocytes

confirms the diagnosis of Gaucher disease. Gaucher disease is an inherited

lysosomal storage disease that is caused by a genetic defect in the lysosomal

enzyme glucocerebrosidase. This enzyme is responsible for the hydrolytic

cleavage of glucosylceramide to glucose and ceramide. What is the function of

lysosomes? What will their failure lead to in the cell?
