    en.wikipedia.org/wiki/Smoker's_face

    Smoker's face describes the characteristic changes that happen to the faces of many people who smoke tobacco products. [1] [2] Smoking causes damage to the skin by depleting the skin of oxygen and nutrients. [3] The general appearance is of accelerated ageing of the face, with a characteristic pattern of facial wrinkling and sallow coloration.

  3. Beta-actin - Wikipedia

    en.wikipedia.org/wiki/Beta-actin

    Actin beta (HUGO Gene Nomenclature Committee abbreviation ACTB/ACTB) is one of six different actin isoforms which have been identified in humans. This is one of the two nonmuscle cytoskeletal actins. Actins are highly conserved proteins [5] [6] that are involved in cell motility, structure and integrity. Alpha actins are a major constituent of ...

    en.wikipedia.org/wiki/Actin,_cytoplasmic_2

    Actin, cytoplasmic 2, or gamma-actin is a protein that in humans is encoded by the ACTG1 gene. [5] Gamma-actin is widely expressed in cellular cytoskeletons of many tissues; in adult striated muscle cells, gamma-actin is localized to Z-discs and costamere structures, which are responsible for force transduction and transmission in muscle cells.

    Smoker melanosis in a patient consuming 2 packs of cigarette per day. Smoking or the use of nicotine-containing drugs is the cause to Smoker's melanosis. [10] [11] Tar-components (benzopyrenes) are also known to stimulate melanocytes to melanin production, and other unknown toxic agents in tobacco may also be the cause.

    en.wikipedia.org/wiki/Actin

    Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils.It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm.

    en.wikipedia.org/wiki/Effects_of_nicotine_on...

    A 2015 review concluded that "Nicotine acts as a gateway drug on the brain, and this effect is likely to occur whether the exposure is from smoking tobacco, passive tobacco smoke or e-cigarettes." [25] Nicotine may have a profound impact on sleep. [26] The effects on sleep vary after being intoxicated, during withdrawal, and from long-term use ...

  9. Stomatitis nicotina - Wikipedia

    Pipe smoking produces more heat on the palate than any other forms of smoking. Long-term drinking of very hot beverages can also cause a similar condition. The severity of the changes correlates with the frequency of the habit. [6] The prevalence depends on a society's use of consuming hot beverages and of smoking in its various forms.
