Tree Man Video
Tree Man Video Alicia Berger 12,662 Views • 2 years ago

32 year old Dede Kosawa, also known as 'Tree Man', is one of the world's most extraordinary people. He lives in a remote village in Indonesia with his two children, trying to care for them. Dede, a former fisherman, has an incredible skin condition: he has root like structures growing out of his body - branches that can grow up to 5cm a year and which protrude from his hands and feet, and welts covering his whole body.
He is known locally as ‘Tree Man’ and his condition has baffled local doctors for 20 years. In an attempt to earn a living to support his family, he is part of a circus troupe, displaying his 'Tree Man' limbs along with others afflicted with skin deformities in ‘freak’ shows.
Dr Anthony Gaspari, a world expert in skin conditions from the University of Maryland travels to Indonesia to attempt to diagnose 'Tree Man' Dede’s mysterious condition. He takes skin samples for biopsies back in the USA. What will he discover?
We go on an intimate journey with the extraordinary 'Tree Man' Dede, as he tries to eek out a living in a circus troupe to support his family, and as he is given medical help by Dr Gaspari. The identification and possible cure of his condition, could change his whole life.
Half way across the world, in Romania, farmer Ion Toader is discovered to have a similar extraordinary ‘Tree Man’ condition, with growths all over his hands. He has not been able to drive a tractor for five years. A Romanian surgeon offers to give him an operation to remove his growths.
Will it be successful, and how will it change Ion’s life?

Neurotransmitters are endogenous chemicals which transmit signals from a neuron to a target cell across a synapse. Neurotransmitters are packaged into synaptic vesicles clustered beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may also follow graded electrical potentials. Low level "baseline" release also occurs without electrical stimulation. Neurotransmitters are synthesized from plentiful and simple precursors, such as amino acids, which are readily available from the diet and which require only a small number of biosynthetic steps to convert. The chemical identity of neurotransmitters is often difficult to determine experimentally. For example, it is easy using an electron microscope to recognize vesicles on the presynaptic side of a synapse, but it may not be easy to determine directly what chemical is packed into them. The difficulties led to many historical controversies over whether a given chemical was or was not clearly established as a transmitter. In an effort to give some structure to the arguments, neurochemists worked out a set of experimentally tractable rules. According to the prevailing beliefs of the 1960s, a chemical can be classified as a neurotransmitter if it meets the following conditions: * There are precursors and/or synthesis enzymes located in the presynaptic side of the synapse. * The chemical is present in the presynaptic element. * It is available in sufficient quantity in the presynaptic neuron to affect the postsynaptic neuron; * There are postsynaptic receptors and the chemical is able to bind to them. * A biochemical mechanism for inactivation is present. There are many different ways to classify neurotransmitters. Dividing them into amino acids, peptides, and monoamines is sufficient for some classification purposes. Major neurotransmitters: * Amino acids: glutamate, aspartate, D-serine, γ-aminobutyric acid (GABA), glycine * Monoamines and other biogenic amines: dopamine (DA), norepinephrine (noradrenaline; NE, NA), epinephrine (adrenaline), histamine, serotonin (SE, 5-HT), melatonin * Others: acetylcholine (ACh), adenosine, anandamide, nitric oxide, etc. In addition, over 50 neuroactive peptides have been found, and new ones are discovered regularly. Many of these are "co-released" along with a small-molecule transmitter, but in some cases a peptide is the primary transmitter at a synapse. β-endorphin is a relatively well known example of a peptide neurotransmitter; it engages in highly specific interactions with opioid receptors in the central nervous system. Single ions, such as synaptically released zinc, are also considered neurotransmitters by some[by whom?], as are some gaseous molecules such as nitric oxide (NO) and carbon monoxide (CO). These are not classical neurotransmitters by the strictest definition, however, because although they have all been shown experimentally to be released by presynaptic terminals in an activity-dependent way, they are not packaged into vesicles. By far the most prevalent transmitter is glutamate, which is excitatory at well over 90% of the synapses in the human brain. The next most prevalent is GABA, which is inhibitory at more than 90% of the synapses that do not use glutamate. Even though other transmitters are used in far fewer synapses, they may be very important functionally—the great majority of psychoactive drugs exert their effects by altering the actions of some neurotransmitter systems, often acting through transmitters other than glutamate or GABA. Addictive drugs such as cocaine and amphetamine exert their effects primarily on the dop

Bigger Muscles?? Victims of Synthol and non-muscle developing methods
Bigger Muscles?? Victims of Synthol and non-muscle developing methods Doctor 16,486 Views • 2 years ago

Some bodybuilders, particularly at professional level, use substances such as "site enhancement oil", commonly known as synthol, to mimic the appearance of developed muscle where it may otherwise be disproportionate or lagging. This is known as "fluffing". Synthol is 85% oil, 7.5% lidocain, and 7.5% alcohol.Use is legal and many brands are available on the internet.The use of injected oil to enhance muscle appearance had previously been used in the late 19th century before being abandoned due to health risks such as sclerosing lipogranuloma. Its use was revived more recently by bodybuilders. Use can cause pulmonary embolisms, nerve damage, infections, stroke, and the formation of oil-filled oleomas, cysts or ulcers in the muscle. Sesame oil is often used, which can cause allergic reactions such as vasculitis. An aesthetic issue is drooping of muscle under gravity. Surgical methods are also often employed to remove steroid-related gynecomastia in male bodybuilders, and breast implants in female bodybuilders who wish to retain a feminine physique, which can be compromised in terms of breast reduction by intense dieting.
