Wiele osób nie zdaje sobie sprawy, jak dużą rolę w procesie kształcenia przyszłych lekarzy odgrywają symulatory. Tu można przeczytać więcej o symulacji medycznej.

Kolejne wielkie odkrycie medyczne Aspiryna. Tu jest historia aspiryny w Wikipedii. Wynika z niej, że już w czasach starożytnych stosowano korę wierzby i inne surowce roślinne bogate w kwas acetosalicylowy. Współcześnie duża sprzedaż aspiryny wynika z jej działania przeciw zakrzepowego. Jest ono wykorzystywane do zapobiegania udarom i zawałom.

i learned that in the 1800s, chemists working with willow bark extracts discovered that salicylic acid is responsible for the analgesic (pain-reducing) and antipryretic (fever-reducing) effects. In 1893, a German chemist converted salicylic acid to its less acidic ester, know as Aspirin (x)

Bardzo fajny artykuł i super ilustracje. Warto zawsze pamiętać jak wielkim osiągnięciem było odkrycie penicyliny.

Dokonał tego Alexander Fleming i wraz ze swoim zespołem.

#OTD 1928 "WONDER DRUG" Penicillin Discovered Modern medicine saves lives - antibiotics & vaccines By Miriam Kleiman, Public Affairs

Stay tuned: Anti-Vaxxer Ben Franklin's Biggest Regret

During WWI, tens of thousands of service personnel died not from their actual wounds but from sepsis, a massive body-wide infection. At the time, very little could be done to prevent these deaths. However, one of the many who sought to help was bacteriologist Alexander Fleming, who as a captain in WWI saw many wounded men die from such infections.

#OTD 1928, Fleming's accidental discovery transformed modern medicine. He'd left a plate of staphylococcus bacteria uncovered, and saw that a mold (similar to the kind found on moldy bread) that had fallen on the culture had killed many of the bacteria. He called the mold by-product penicillin.

“When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer. But I guess that was exactly what I did." ---Dr. Alexander Fleming

Commercial production of penicillin began after the start of WWII. In advance of D-Day, scientists prepared more than two million doses. Government communicators worked with the pharmaceutical industry to produce a robust ad campaign - including posters below from our holdings - to establish penicillin as "the wonder drug." The posters - a snapshot of the time - include a happy soldier smoking while recovering in bed, anti-Japanese propaganda, and concerns about STDs. See Powers of Persuasion online exhibit.

Ciekawe, z materiału wynika, iż Lilak pospolity był już w średniowieczu stosowany na cukrzycę.

i learned that the anti-diabetic medication, metformin, is derived from French lilacs. In medieval times, French lilac was used to treat the symptoms of a condition we now know today as diabetes mellitus (x)

Bardzo ciekawe odkrycie - gen, który zwiększa dwukrotnie ryzyko śmierci na COVID-19.

Researchers have identified a version of a gene that doubles a person’s risk of severe COVID-19 and doubles the risk of death from the disease for people under 60.

The gene, LZTFL1, is involved in the regulation of lung cells in response to infection. When the risky version of the gene is present, cells lining the lungs seem to do less to protect themselves from infection with the coronavirus SARS-CoV-2.

The gene version that raises COVID-19 risk is present in 60 percent of people of South Asian ancestry, 15 percent of people of European ancestry, 2.4 percent of people with African ancestry and 1.8 percent of people with East Asian ancestry.

Decellularization is the name for a tissue engineering technique which is designed to strip the cells from a donor organ, thus leaving nothing but connective tissue that once held the cells in place. It’s referred to as a “ghost organ” for it’s pale appearance. It can then be reseeded with the patient’s cells. The goal is to render an organ that can be transplanted into a patient without the tissue being rejected.
