  • Retinoblastoma protein, dysfunctional in several cancers, belongs to the pocket protein family and is a recruiter of chromatin remodeling enzymes

    The retinoblastoma protein (protein name abbreviated Rb; gene name abbreviated Rb, RB or RB1) is a tumor suppressor protein that is dysfunctional in several major cancers. One function of pRb is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide. When the cell is ready to divide, pRb is phosphorylated, inactivating it, and the cell cycle is allowed to progress. It is also a…

  • Isoleucine, Tryptophol, Sleeping Sickness, The Disulfiram Effect and One Trick Hypnotists From Hell

    Isoleucine, Tryptophol, Sleeping Sickness, The Disulfiram Effect and One Trick Hypnotists From Hell

    Isoleucine (symbol Ile or I) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH+3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a hydrocarbon side chain with a branch (a central carbon atom bound to three other carbon atoms). It is classified as a non-polar, uncharged (at physiological pH), branched-chain, aliphatic amino acid. It…

  • Did WHO Study Conclude That Natural Blondes Are Likely To Be Extinct Within 200 Years? – Snopes

    https://www.snopes.com/fact-check/gone-blonde/ Evidently these things or things very like them have been published (here and elsewhere) since at least the time of the Civil War. This quote is said to be from an article dated 1890: The girl with the golden tresses is doomed, and within six hundred years blondes will be extinct. The fate of…

  • Freeze branding aka CryoBranding and the resulting brands, trichoglyphs, is a technique involving a cryogenic coolant instead of heat to produce permanent marks on a variety of animals

    Freeze branding aka CryoBranding and the resulting brands, trichoglyphs, is a technique involving a cryogenic coolant instead of heat to produce permanent marks on a variety of animals

    The coolant is used to lower the temperature of a branding iron such that its application to shaved skin will permanently alter hair follicles. The intense cold destroys the pigmentation apparatus in the animal’s hair follicles, leaving all subsequent hair growth without color. This creates a high-contrast, permanent mark in the shape of the branding iron’s head. A longer application of the cold iron can also…

  • Adenosine

    Adenosine

    Adenosine (symbol A) is an organic compound that occurs widely in nature in the form of diverse derivatives. The molecule consists of an adenine attached to a ribose via a ÎČ-N9–glycosidic bond. Adenosine is one of the four nucleoside building blocks of RNA (and its derivative deoxyadenosine is a building block of DNA), which are essential for all life. Its derivatives include the energy carriers adenosine mono-, di-, and triphosphate, also…

  • Peris

    Peris

    In Persian mythology, Peris are exquisite, winged spirits renowned for their beauty. Peris were later adopted by other cultures. They are described in one reference work as mischievous beings that have been denied entry to paradise until they have completed penance for atonement.[need quotation to verify] Under Islamic influence, Peris became benevolent spirits, in contrast to the mischievous jinn and evil divs (demons). Scholar Ulrich Marzolph [de] indicates an Indo-Iranian origin for peris, which were later[when?] integrated into…

  • Pro-opiomelanocortin (POMC)

    Pro-opiomelanocortin (POMC) is a precursor polypeptide with 241 amino acid residues. POMC is synthesized in corticotrophs of the anterior pituitary from the 267-amino-acid-long polypeptide precursor pre-pro-opiomelanocortin (pre-POMC), by the removal of a 26-amino-acid-long signal peptide sequence during translation.  “pro-opiomelanocortin preproprotein [Homo sapiens] – Protein – NCBI”. www.ncbi.nlm.nih.gov. Retrieved 30 December 2020. POMC is part of the central melanocortin system. Function POMC is cut (cleaved) to give rise to multiple peptide hormones. Each of these peptides is packaged…
