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 ...
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]
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)
A 14th magnitude star situated 26" from Alpha Lupi is listed as a companion in double star catalogues. [ 16 ] This star is a proper motion member of the Upper Centaurus–Lupus sub-group in the Scorpius–Centaurus OB association , the nearest such co-moving association of massive stars to the Sun. [ 6 ] This is a gravitationally unbound ...
This is a list of the nearest giant stars (luminosity class III or II) to the Earth, located at a distance of up to 100 light-years ... 10.77 ± 0.45 [20] 1.27 [21]

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 ...
