Chloroprene, also known as 2-chloro-1,3-butadiene, is a colorless liquid with a pungent odor. It is synthesized through a multi-step process involving the chlorination of butadiene. Chloroprene is primarily used in the production of neoprene, a synthetic rubber known for its resilience, oil resistance, and flame retardancy. Neoprene is extensively used in a wide range of applications, including wetsuits, diving gear, gaskets, hoses, and electrical insulation. The study of chloroprene is crucial due to its potential health hazards. Exposure to chloroprene can irritate the eyes, skin, and respiratory system, and prolonged exposure has been linked to liver and kidney damage. Understanding its synthesis, properties, and effects is essential for ensuring safe handling and usage. Chloroprene is also of interest in the development of novel materials and polymers with enhanced properties.'

| Alcoholism A primary, chronic disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. The disease is often progressive and fatal. It is characterized by impaired control over drinking, preoccupation with the drug alcohol, use of alcohol despite adverse consequences, and distortions in thinking, most notably denial. Each of these symptoms may be continuous or periodic.

| Vitamin B 12 Deficiency A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis.

| Brain Neoplasms Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain. | 0 | 2.03 | 1 | 0 |

| Meningioma A relatively common neoplasm of the CENTRAL NERVOUS SYSTEM that arises from arachnoidal cells. The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive, although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region, cerebral convexity, sphenoidal ridge, olfactory groove, and SPINAL CANAL.

| Leukemia A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells. (From The Merck Manual, 2006) | 0 | 2.92 | 1 | 0 |
