Giant stars have radii up to a few hundred times the Sun and luminosities over 10 times that of the Sun. Stars still more luminous than giants are referred to as supergiants and hypergiants. A hot, luminous main-sequence star may also be referred to as a giant, but any main-sequence star is properly called a dwarf, regardless of how large and ...
In August 2020, the U.S. Food and Drug Administration (FDA) became aware of nitrosamine impurities in certain samples of rifampin. [62] The FDA and manufacturers are investigating the origin of these impurities in rifampin, and the agency is developing testing methods for regulators and industry to detect the 1-methyl-4-nitrosopiperazine (MNP ...
Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi). [1] The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars (Pistol Star, Rho Cassiopeiae, Betelgeuse, and VY Canis Majoris)

Alpha Lupi (α Lupi, α Lup), also named Uridim, [11] is a blue giant star, and the brightest star in the southern constellation of Lupus.According to the Bortle Dark-Sky Scale, its apparent visual magnitude of 2.3 [2] makes it readily visible to the naked eye even from highly light-polluted locales.
It contains genes rifG through rifN, which were shown to biosynthesize AHBA.[10] RifK, rifL, rifM, and rifN are believed to act as transaminases in order to form the AHBA precursor kanosamine. [13] [14] "RifH" encodes aminoDAHP synthase that catalyzes the condensation between 1-deoxy-1-imino-d-erythrose 4-phosphate and phosphoenolpyruvate. [15]
It is a fixed dose combination of rifampicin, isoniazid, and pyrazinamide. [1] It is used either by itself or along with other antituberculosis medication. [1] It is taken by mouth. [1] Side effects are those of the underlying medications. [1] These may include poor coordination, loss of appetite, nausea, joint pain, feeling tired, and numbness ...
