Acute toxicity. The oral LD 50 range of aflatoxin B 1 is estimated to be 0.3–17.9 mg/kg body weight for most animal species. [ 35 ] For instance, the oral LD 50 of aflatoxin B 1 is estimated to be 17.9 mg/kg body weight in female rats and 7.2 mg/kg body weight in male rats. Still in male rats, the intraperitoneal LD 50 of aflatoxin B 1 is ...
Aflatoxin M 1 is present in the fermentation broth of Aspergillus parasiticus, but it and aflatoxin M 2 are also produced when an infected liver metabolizes aflatoxin B 1 and B 2. Aflatoxin B 1 and B 2 (AFB), produced by A. flavus and A. parasiticus; Aflatoxin G 1 and G 2 (AFG), produced by some Group II A. flavus and Aspergillus parasiticus [19]
Polymyxin B, sold under the brand name Poly-Rx among others, is an antibiotic used to treat meningitis, pneumonia, sepsis, and urinary tract infections. [ 1 ] While it is useful for many Gram negative infections, it is not useful for Gram positive infections. [ 1 ] It can be given by injection into a vein, muscle, or cerebrospinal fluid or ...
Benfotiamine (rINN, or S-benzoylthiamine O-monophosphate) is a synthetic, fat-soluble, S -acyl derivative of thiamine (vitamin B1) that is approved in some countries as a medication or dietary supplement to treat diabetic sensorimotor polyneuropathy. Benfotiamine was developed in late 1950s in Japan. [ 1 ][ 2 ]
The number 2,147,483,647 is the eighth Mersenne prime, equal to 2 31 − 1. It is one of only four known double Mersenne primes. [ 1 ] The primality of this number was proven by Leonhard Euler, who reported the proof in a letter to Daniel Bernoulli written in 1772. [ 2 ] Euler used trial division, improving on Pietro Cataldi 's method, so that ...
The recommended dose generally ranges from: 0.25 to 1.25 mg a day for the treatment of female pattern hair loss. 2.5 to 5 mg a day for male pattern hair loss. Confused about your dosage? Consult ...
B1 cell. B1 cells are a sub-class of B cell lymphocytes that are involved in the humoral immune response. They are not part of the adaptive immune system, as they have no memory, but otherwise, B1 cells perform many of the same roles as other B cells: making antibodies against antigens and acting as antigen-presenting cells.
The absorption spectrum of both the chlorophyll a and the chlorophyll b pigments. The use of both together enhances the size of the absorption of light for producing energy. Chlorophyll b is a form of chlorophyll. Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polar solvents because of ...
