45. What is Keytruda, that was recently mentioned in news?
[A] An immunotherapy drug
[B] A type of virus
[C] Rare medicinal plant
[D] Newly discovered species of Fish
[B] A type of virus
[C] Rare medicinal plant
[D] Newly discovered species of Fish
Correct Answer: A [An immunotherapy drug]
Notes:
Keytruda is an immunotherapy drug (pembrolizumab) used globally to treat cancers such as lung, cervical, renal cell, and aggressive breast cancer. It is manufactured by Merck & Co. and belongs to a class of drugs called checkpoint inhibitors. It is a monoclonal antibody, meaning it is a laboratory-made molecule designed to target specific cancer-related proteins. It blocks PD-1 receptors on T-cells, preventing interaction with PD-L1 on cancer cells, thereby enabling the immune system to attack cancer cells. In India, it is available in tertiary care hospitals, while indigenous CAR-T therapy like NexCAR19 has also been developed for cancer treatment.

[A] Indonesia
[B] France
[C] India
[D] China
[B] France
[C] India
[D] China
Correct Answer: D [China]
Notes:
China has announced the discovery of a new lunar mineral named Cerium-Magnesium Changesite, adding to knowledge of extraterrestrial materials and lunar geology. The mineral was identified in a lunar meteorite called Pakepake 005, the first such meteorite found in China. This meteorite is a small spherical rock weighing about 44 grams with a dark molten outer layer. The mineral itself is colourless, transparent, and brittle, yet scientifically significant. It shows fluorescent properties, meaning it can emit light under certain conditions. This fluorescence has potential applications in advanced technologies like next-generation LED materials.

[A] Viral infection
[B] Genetic disorder
[C] Autoimmune inflammatory disease
[D] Nutritional deficiency
[B] Genetic disorder
[C] Autoimmune inflammatory disease
[D] Nutritional deficiency
Correct Answer: C [Autoimmune inflammatory disease]
Notes:
A recent multicenter study on Kawasaki Disease evaluated adding Prednisolone to standard treatment. The study found that prednisolone did not reduce the incidence of coronary artery lesions after one month. Kawasaki Disease, also called mucocutaneous lymph node syndrome, is a rare disease causing fever and inflammation of blood vessels. It mainly affects children below 5 years and is more common in boys than girls. The disease was first identified by Tomisaku Kawasaki in 1967 in Japan. It is the most common acquired (not present at birth) heart disease in children in developed countries. The immune system attacks blood vessels, especially coronary arteries, leading to inflammation and swelling.
