    Study Notes

    Leading Figures in Science

    • Rene Descartes - is a notable figure in philosophy and mathematics, contributing influential ideas to both fields.
    • Carl Ludwig - a German physiologist known for his contributions to understanding the circulatory system.
    • Ernst Brucke - an Austrian physiologist who was a proponent of the theory of mechanism, which states that all living organisms are machines.
    • Emil Du-Bois Reymond - a German physiologist and physicist who played a significant role in the development of electrophysiology, studying the electrical properties of living tissue.

    Darwinists

    • Darwinists believe that man is not unique and there is continuity between man and animals.
    • Darwin's publication "Origin of Species" is considered the foundation of evolutionary biology.

    Animal Chemistry

    • Antoine Francois de Fourcroy - isolated urea from urine samples and advocated for chemical laboratories near wards for analysis of urine from sick patients.
    • Friedrich Wohler - synthesized urea in vitro, demonstrating that organic substances can be synthesized without a "vital force".
    • Wöhler's experiment bridged the gap between the organic and inorganic worlds, providing evidence against vitalism.

    Blood Glucose & Lipid Testing

    • The HbA1c test evaluates blood glucose levels over a three-month period.
    • Lipid profile tests are used to assess cardiovascular disease risks.
    • These tests measure the levels of triglycerides, cholesterol, and lipoproteins.

    Lipoproteins

    • Lipoproteins are particles made up of fats and proteins.
    • LDL, often referred to as "bad cholesterol," transports cholesterol from the liver to tissues.
    • HDL, referred to as "good cholesterol," transports cholesterol from tissues back to the liver for metabolism.

    Variolation

    • Variolation is a method of exposing patients to dried smallpox crusts to induce immunity.

    Edward Jenner

    • In 1798, Jenner started the practice of vaccination, using cowpox material to immunize against smallpox.
    • His observations showed that milkmaids with cowpox were immune to smallpox.

    Louis Pasteur

    • Pasteur observed and coined the term "attenuation," which signifies the weakening of a pathogen.
    • He demonstrated that attenuated pathogens can be used as vaccines.
    • He successfully cultured the bacterium causing fowl cholera and showed that old cultures, when injected into chickens, did not cause the disease.

    Anti-HBs Test (Hepatitis B Surface Antibody)

    • The presence of anti-HBs indicates immunity from Hepatitis B infection.
    • Anti-HBs are produced by individuals who have been vaccinated against Hepatitis B or those recovered from the infection.

    WIDAL Test

    • This test is used to detect Enteric and Typhoid fever.
    • It identifies antibodies against Salmonella bacteria.

    Dengue IgG/IgM Test

    • This test screens for dengue viral infection.
    • It aids in diagnosing primary and secondary infections.
    • IgG Positive Only: Indicates past dengue infection.
    • IgM Positive Only: Indicates primary (first-time) dengue infection.
    • Both IgG and IgM Positive: Indicates secondary dengue infection.

    Blood Type Inheritance

    • If the mother's genotype is either AO or AA and the father's is AB, there are eight possible genotypes for their offspring.
    • The possible phenotypes for the offspring are blood type AB (37.5%), blood type A (50%), and blood type B (12.5%).
