Q & A

What is Nihonium and why is it significant?

Nihonium is a super heavy synthetic element (Element 113) discovered by Professor Kusuke Morita at Kyushu University. It holds significance as the first element named by Japanese scientists and also marks the first time an element was named by an Asian country.

What is agar, and what are its uses?

Agar is a jelly-like substance discovered in Japan around 1658 by the scientist Mino Taro Zeman. It is used in desserts, as a bacterial culture medium, a laxative, a vegetarian substitute for gelatin, and as a thickener for soups and ice cream. It also helps in fruit preservation.

What is CRISPR, and how did Japanese scientists contribute to it?

CRISPR is a powerful genetic modification tool. In 1987, Japanese scientist Yoshizumi Ishino discovered the CRISPR molecule, which, together with the Cas9 enzyme, allows precise modification of the genetic material of living beings, revolutionizing genetic research.

What role did ephedrine play in modern medicine?

Ephedrine is a compound synthesized by Japanese chemist Nagai Nagayoshi in 1885. It can increase blood pressure and act as a bronchodilator. It is also used to treat motion sickness, short-term weight loss, and has applications in treating respiratory conditions.

What are the uses of epinephrine (adrenaline)?

Epinephrine, or adrenaline, was discovered in 1900 by Japanese chemist Jokichi Takamine. It is a key hormone for the body’s fight-or-flight response and is used to treat conditions such as anaphylaxis, cardiac arrest, asthma, and superficial bleeding.

How did the Japanese contribute to the development of anesthesia?

In 1804, Japanese doctor Hanaoka Seishu developed the first general anesthesia, Su-sensin. His groundbreaking work allowed him to perform surgeries, including cancerous tumor removal, in a manner that would be impossible without anesthesia.

What is methamphetamine, and what were its medical applications?

Methamphetamine, first synthesized by Nagai Nagayoshi in 1894 and later medically formulated by Akira Ogata in 1919, is used to treat ADHD. It increases attention and focus, although it has potential for misuse and side effects, including dependency and cardiovascular issues.

What impact did Japanese scientist Akira Endo have on cardiovascular health?

Akira Endo discovered the first statin, mevastatin, which is part of a class of drugs that reduce cholesterol and help prevent cardiovascular disease. Statins significantly lower the risk of heart attacks and strokes.

How did the discovery of thiamine impact health in Japan?

Thiamine, the first water-soluble B vitamin, was isolated after a series of studies on beriberi disease by Japanese surgeon Takaki Kanahiro. His work on improving diets among Japanese Navy personnel helped eliminate beriberi, a disease caused by vitamin B1 deficiency.

What is the significance of MSG, and how was it discovered?

MSG, or monosodium glutamate, is responsible for the savory umami taste in foods. It was first isolated by Japanese chemist Kikunae Ikeda in 1908. It has since become a widely used flavor enhancer in cooking, especially in Asian cuisines.

How did Akira Yoshino contribute to modern technology?

In 1983, Akira Yoshino contributed to the development of lithium-ion batteries, which are used in everyday electronics, including smartphones and electric vehicles. His innovation made batteries lighter, smaller, and more efficient, revolutionizing modern technology.

What is GFP (green fluorescent protein), and why is it important?

GFP, discovered by Japanese scientist Osamu Shimomura in the 1960s, is a glowing protein found in jellyfish. It has since become essential in fluorescent microscopy and is used to mark proteins, cells, and even entire organisms, aiding in biological research.

What role does immunoglobulin E (IgE) play in immune responses?

Immunoglobulin E (IgE), discovered by Japanese immunologist Kimishigi Ishizaka in 1966, plays a crucial role in the immune system by defending against parasitic infections and venom. It is also important in allergic reactions and has potential as a cancer immunotherapy.

How did Satoshi Ōmura contribute to the fight against parasitic diseases?

Satoshi Ōmura, a Japanese scientist, isolated ivermectin from the bacterium *Streptomyces avermitilis*. This molecule is effective against various parasitic infections and has been instrumental in reducing diseases like river blindness and lymphatic filariasis.
