LSD is one of the most potent, mood-changing chemicals. It is manufactured from lysergic acid, which is found in the ergot fungus that grows on rye and other grains. It is produced in crystal form in illegal laboratories, mainly in the United States. These crystals are converted to a liquid for distribution. It is odorless, colorless, and has a slightly bitter taste.

Syringomyelia
Syringomyelia samer kareem 3,632 Views • 3 years ago

Syringomyelia (sih-ring-go-my-E-lee-uh) is the development of a fluid-filled cyst (syrinx) within your spinal cord. Over time, the cyst may enlarge, damaging your spinal cord and causing pain, weakness and stiffness, among other symptoms. Syringomyelia has several possible causes, though the majority of cases are associated with a condition in which brain tissue protrudes into your spinal canal (Chiari malformation). Other causes of syringomyelia include spinal cord tumors, spinal cord injuries and damage caused by inflammation around your spinal cord. If syringomyelia isn't causing any problems, monitoring the condition may be all that's necessary. But if you're bothered by symptoms, you may need surgery.

Is oncology the right choice for you? samer kareem 1,535 Views • 3 years ago

What combines research opportunities, intellectual challenge, and international collaboration in the study of a disease which affects many organs of the body and all sectors of society? And demands that specialists from many different backgrounds work together to crack sometimes intractable problems? It is, of course, oncology. As a career choice, it's demanding; it takes passion coupled with a willingness to put in the hours and to learn how to discuss death honestly and sensitively. But for the right person, it can be immensely rewarding.

Decompression is a surgical procedure that is performed to alleviate pain caused by pinched nerves (neural impingement). During a lumbar decompression back surgery, a small portion of the bone over the nerve root and/or disc material from under the nerve root is removed to give the nerve root more space and provide a better healing environment. There are two common types of spine surgery decompression procedures: Microdiscectomy Lumbar Microdiscectomy Microdiscectomy Surgery Video A microdiscectomy (a microdecompression) is typically performed for pain from a lumbar herniated disc. The surgery is considered reliable for leg pain caused by the herniated disc, most commonly called sciatica by patients, and most commonly referred to by medical practitioners as a radiculopathy.

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,536 Views • 3 years ago

The pathobiology of MM is complex and the root underlying cause of myeloma is the multistep genetic changes in the postgerminal center B cell. In addition, the bone marrow microenvironment plays a crucial role.[2] The interaction between myeloma cells and the microenvironment is mediated through adhesive interactions via cell-surface receptors, paracrine loops involving several cytokines, such as IL-6, VEGF and IL-10, and suppression of cell-mediated immunity.[2–4] IMiDs modulate many of these interactions leading to decreased myeloma cell growth and survival. Thalidomide was the first IMiD introduced to treat MM. It was initially synthesized in Germany in the late 1950s to treat insomnia and morning sickness. It was withdrawn from the market in 1961 because of its teratogenic effects. Its immunomodulatory properties were realized when it was observed to improve erythema nodosum leprosum, a painful immunologic reaction of leprosy, leading to its approval by the FDA in 1998 with tight prescribing and marketing regulations. Subsequent research showed the diverse mechanism of action of thalidomide including its immunomodulatory effect by inhibition of de novo IgM antibody synthesis,[5] modulation of the T-cell subset by increasing the T-helper cells, inhibitory effects on the TNF-α and antiangiogenic activity leading to its use in MM. Significantly higher response rates in combination with dexamethasone led to its approval in the treatment of newly diagnosed MM in 2006. Lenalidomide, a second-generation IMiD, was developed from the structural backbone of the thalidomide molecule by the addition of an amino group (NH2-) at position 4 of the phthaloyl ring and removal of the carbonyl group (C = O) of the 4-amino-substituted phthaloyl ring (Table 1).[6] In addition to immunomodulatory effects, other mechanisms of action have been described such as direct cytotoxicity via induction of apoptosis, inhibition of cell adhesion molecules and inhibition of growth signals that promote bone marrow angiogenesis

Acute Respiratory Distress Syndrome Pathophysiology
Acute Respiratory Distress Syndrome Pathophysiology samer kareem 2,203 Views • 3 years ago

ARDS was recognized as the most severe form of acute lung injury (ALI), a form of diffuse alveolar injury. The AECC defined ARDS as an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. The severity of hypoxemia necessary to make the diagnosis of ARDS was defined by the ratio of the partial pressure of oxygen in the patient’s arterial blood (PaO2) to the fraction of oxygen in the inspired air (FiO2). ARDS was defined by a PaO2/FiO2 ratio of less than 200, and in ALI, less than 300. This definition was further refined in 2011 by a panel of experts and is termed the Berlin definition of ARDS. [3] ARDS is defined by timing (within 1 wk of clinical insult or onset of respiratory symptoms); radiographic changes (bilateral opacities not fully explained by effusions, consolidation, or atelectasis); origin of edema (not fully explained by cardiac failure or fluid overload); and severity based on the PaO2/FiO2 ratio on 5 cm of continuous positive airway pressure (CPAP). The 3 categories are mild (PaO2/FiO2 200-300), moderate (PaO2/FiO2 100-200), and severe (PaO2/FiO2 ≤100).

Weiße Punkte Auf Der Haut, Vitiligo Symptome, Vitiligo Behandlung, Weiße Flecken Haut Pilz--- http://vitiligo-heilung.info-pro.co --- Wie wird Vitiligo diagnostiziert? Der Arzt wird als allererstes nach den offensichtlichsten Anzeichen von Vitiligo suchen, den weißen Hautflecken. Es gibt jedoch auch noch weitere diagnostische Methoden. In manchen Fällen kann Vitiligo vererbt sein. Der Arzt wird also erörtern, ob die Eltern oder andere Familienmitglieder des Patienten an der Hautstörung litten (oder leiden), ob in der Familie Fälle von Autoimmunstören, und ob der Patient bereits ergraute bevor er das Alter von 35 Jahren erreichte. Manchmal wird sich der Arzt auch einer Blutentnahme oder Gewebe-Biopsie bedienen, um durch Laboruntersuchungen abzusichern, dass tatsächlich Vitiligo vorliegt. Behandlung von Vitiligo Die Behandlung von Vitiligo ist in ständiger Weiterentwicklung begriffen. Die gegenwärtig eingesetzten Behandlungsmethoden hängen vor allem vom Schweregrad der Hautstörung ab. Allerdings spielt auch die Krankenversicherung des Patienten eine Rolle, denn die meisten verfügbaren Behandlungsverfahren sind äußerst kostspielig. Dennoch sind sie nicht immer effektiv und können zudem auch noch eine Masse an Nebenwirkungen mit sich bringen. Patienten, die sich die teuren Behandlungen nicht leisten können, bleibt meistens nichts anderes übrig als zu lernen, mit der Erkrankung zu leben. Vitiligo ist zwar nicht lebensbedrohlich, aber sie kann einen schweren Einfluss auf das Selbstwertgefühl und Selbstbewusstsein des Patienten haben.
