A 56-year-old man receives radiation therapy for a squamous cell carcinoma of the lung. Despite therapy, the tumor progressively increases in size, and he dies 6 months later. His tumor cells contain a point mutation in the p53 gene (TP53), leading to an inactive gene product. Based on this finding, the progressive tumor growth despite irradiation therapy is most likely to be related to a defec...

    Thank you for the valuable information a lot❤ I have skolyosis , intervertebral disc protrusion at the L5-51 level, and polyneiropathy for almost 2 years in my legs and feets. I took multiple vitamins of B vitamins, but, still my sensation is slow than it was, and sometimes it is more cold than my hands. I actually took analysis of ENM. It says:The general conclusion with stimulation ENMG of the lower extremities was revealed - duumelination of the tibial nerves on both sides by motor fibers. By sensory fibers, demyelination of the deep branches of the fibular nerve on the right, the gastrocnemius nerve on both sides, the median nerve on the left.

    chemistry of psychoactive substances in so interesting but most drug users who are heroin addicts don't ever concern themselves with such information in my experience, which I find a shame cos it could help them and even save their lives on occasion cos they would know about interactions. I love how slight changes to the functional group of a chemical, alters it's effects, sometimes markedly so, like in the case of Fentanyl and it's structural analog Carfentanil which is 1000 times the potency.

    A little girl pouting? That doesn't show us ALL that the mentalis muscle does. A photo of someone 'sticking their chin out' would show the other side of the story. Both expressions require the mentalis. Pouting requires only the lower fibers to contact, while the upper fibers are left loose and relaxed, resulting in lip eversion. The stiff "chin stuck out' expression requires BOTH the lower and upper fibers to contract and 'stiffen' the whole mentalis complex (lower lip and chin). Go ahead and use the mentalis to pout if you must, but that's not the end of the story for the mentalis muscle. It should be called the 'elevator muscle' or the 'dynamic muscle'. Better still, the 'dynamo of the human face'. You owe that 'crease' below your lower lip (labiomental fold) to the mentalis muscle. All the action takes place through that crease and that's because both mentalis muscles are firmly anchored to your chin bone beneath your incisor roots. The mentalis muscle works tirelessly to elevate the lower lip against gravity, dedicatedly holding the lower lip up in a raised position where it is always lightly approximated to the upper lip and ready for action. That action may involve relaxed, loose lipped expression, or firm mouth closure (bolshy OR pouty), or it may involve talk, drink, eat, laugh, cry, kiss, whistle, pout, or grimace. I just wish anatomy educators would impress upon students that the mentalis muscle fibers are arranged in a way they have a dual role -- the upper fibers and lower fibers have different and opposing actions. This creates a muscle capable of extraordinary dynamic motion right there on your chin. How else would you be able to maintain lip closure during chewing if the mentalis wasn't seamlessly raising and lowering your lower lip with every rhythmic parting of your teeth? That's all provided it's anchored firmly to your chin bone, like a mussel anchored to a moreing. Otherwise it would flap about in the skin and create some weird, bizarre deformations. The anchoring to the bone is all important for the 'hinged lever action' of this muscle, which I personally think is the muscle that most makes us human. There is rarely a time (even in sleep) that the mentalis is not 'active and toned'. It's on constant sentry duty, keeping the lower lip elevated and ready to spring into dynamic action. This is all possible because of 1. the anchoring to the bone 2. the dual action of the muscle fibers (some heading up to the lip, some splaying down over the chin and inserting into the skin 3. the superb anatomical architecture of the labiomental fold. There is some seriously amazing functional anatomy going on with the human face, and the mentalis is front and centre to that action. Paralysis of this muscle, or loss of anchoring to the bone, leads to lip and chin slumping, drooling and all manner of loss of human oral function, including precise, clear language. The 'pouting muscle'. Seriously? Mentalis is way more than that.
