Context paragraphs:
Alcohol (drug): Alcohol, also known by its chemical name ethanol, is a psychoactive drug found as the active ingredient in alcoholic beverages such as beer, wine, and distilled spirits.  It is one of the oldest and most common recreational drugs, causing the characteristic effects of alcohol intoxication or "drunkenness".  Among other effects, alcohol produces euphoria, decreased anxiety, increased sociability, sedation, impairment of cognition, memory, and motor function, and generalized depression of central nervous system function.  Ethanol is the only type of alcohol that is found in alcoholic beverages and is commonly used for recreational purposes; other alcohols such as methanol and isopropyl alcohol are toxic and potentially lethal.

Rosaura Zapata: Rosaura Zapata (1876?  – July 23, 1963) was a Mexican educator who helped to found the national system of education.  She received Mexico's highest national honor when it was inaugurated in 1954, the Belisario Domínguez Medal of Honor.

Melior Discovery: Melior Discovery, Inc. is a private biopharmaceutical company based in Exton, Pennsylvania, USA.  The company specializes in drug repositioning and has established a proprietary phenotypic screening platform that it uses for this purpose.  Melior also offers certain contract research organization (CRO) services comprising animal models representing different disease conditions.  The Company has issued press releases disclosing partnerships with Pfizer, Merck & Co., Johnson & Johnson, and AstraZeneca, all citing the use of the company’s drug repositioning technology.  Melior Discovery has also used its technology to discover its own drug candidates.  In March 2009 the Food and Drug Administration (FDA) approved the company’s Investigational New Drug (IND) application for a type 2 diabetes therapeutic candidate, MLR-1023.  In 2013 the company reported a licensing partnership with Bukwang Pharmaceutical Company LTD and the initiation of clinical trials in March 2015.  In June 2016 the company reported positive results from their Phase 2a clinical study in diabetic subjects

System to Retrieve Information from Drug Evidence: The System to Retrieve Information from Drug Evidence (STRIDE) is a United States Drug Enforcement Administration (DEA) program consisting of six subsystems providing information on drug intelligence, statistics on markings found on pills and capsules, drug inventory, tracking, statistical information on drugs removed from the marketplace, utilization of laboratory manpower and information on subsystems analyzed outside of the DEA laboratory system where DEA participated in the seizures.

Cinthya Domínguez: Cinthya Domínguez (born 1982-10-29) is a female weightlifter from Mexico.  She won the silver medal at the 2007 Pan American Games for her native North American country in the – 69 kg weight division.  In 2015 Domínguez was suspended after she failed a drug test (found trace of Oxandrolone).

ADS 9731: ADS 9731 is a star system that consists of six stars.  Four of the stars are visually separate in the sky, forming a visual star system, which was resolved using adaptive optics in 1995.  Two of these stars were themselves found to be spectroscopic binaries in 1998, resulting in a total of six known stars in the system.  It is one of very few multiple star systems known to have at least six members.  The components are organised thus: Aa and Ab are yellow-white main sequence stars of spectral types F4V and F5V and 1.35 and 1.32 solar masses respectively, which orbit each other every 3.27 days.  This pair is in a 450-year orbit with star B, a star of spectral type G4V that has around the same mass as the Sun.  Star C is a yellow white star of spectral type F3V around 1.41 times as massive as the sun, which has just started brightening and moving off the main sequence.  It is in a 1000-year orbit with a pair of stars, Da and Db, a yellow-white main sequence star of spectral type F7V and a red dwarf of spectral type M3V.  Da and Db take 14.28-days to orbit each other.  Finally the system of stars C and Dab, and the system of stars Aab and B, take over 20,000 years to orbit each other.

Type II secretion system: The type 2 secretion system (often referred to as the type II secretion system or the T2SS) is protein secretion machinery found in various species of Gram-negative bacteria, including various human pathogens such as "Pseudomonas aeruginosa" and "Vibrio cholerae".  The type II secretion system is one of six protein secretory systems that are commonly found in gram negative bacteria along with the type I secretion system, the type III secretion system, The type IV secretion system, the chaperone/usher pathway, the autotransporter pathway/type V secretion system and the type VI secretion system (some bacteria also utilize the type VII secretion system).  Like these other systems, the type II secretion system enables the transport of cytoplasmic proteins across the lipid bilayers that make up the cell membranes in gram negative bacteria.

Elaine Bartlett: Elaine Bartlett was a woman charged with a first offense felony for selling cocaine.  Elaine, a mother of four children, spent sixteen years in the Bedford Hills prison in New York.  During the time of Elaine's arrest, New York had just undergone some major changes with their drug laws.  The controversial Rockefeller drug laws caused a major upset and cause many to second-guess the criminal justice system's benign motives.  After he release in 2000, Elaine had no proper resources to help her get back on track with her life but that was not an excuse for her.  Bartlett was a woman on a mission who was going to prove to not only to herself, but to the world that she was going to make it.  After having lived through sixteen years in prison, she became an activist to repeal the Rockefeller drug laws.  Bartlett helped found the Mothers of the Disappeared which is an advocacy group that is fighting to try and repeal the drug laws.  Not only has Bartlett helped found this organization, but she has also gone up against New York state legislators, and delivered speeches at rallies.  Besides the Rockefeller drug laws, Bartlett has also made an impact in attending anti-drug law events in Washington D.C., Philadelphia, and Texas.  While Elaine was still in prison, she wanted to be involved with as many activities as she possibly could in order to keep busy and to show that she had the full potential to better herself and get an education.  In 1999, Bartlett obtained her associate degree from Mercy College while she was still in prison.

EMA401: EMA401 was a drug under development for the treatment of peripheral neuropathic pain.  Trials were discontinued in 2015.  It was initially established as a potential drug option for patients suffering pain caused by postherpetic neuralgia.  It may also be useful for treating various types of chronic neuropathic pains caused by lesions and other diseases affecting the somatosensory system in addition to postherpetic neuralgia.  EMA401 has been implicated in alleviating pains associated with a host of neural abnormalities, ranging from excessive nerve sprouting due to damaged nerve caused by shingles, diabetes, osteoarthritis, HIV and chemotherapy.  EMA401 is a competitive antagonist of angiotensin II type 2 receptor (AT R) being developed by the Australian biotechnology company Spinifex Pharmaceuticals.  It is the S-enantiomer form of the racemate drug EMA400.  Analgesic treatments currently available for pain disorders are unsuited for severe chronic neuropathic pains.  EMA401 is more effective and has virtually no central nervous system side effects in comparison to current drugs for pain relief, such as Neurotin and Lyrica.  Pain pathways of the other functional systems have major molecular and mechanistic differences compared to pain pathways of the peripheral nervous system.  EMA401 target proteins, angiotensin II type 2 receptors, are extremely important for nociception within the peripheral nervous system and less so for nociception within other functional systems.  EMA401 is the first drug on the market that targets angiotensin II type 2 receptors (AT R) with high affinity but has a low affinity for angiotensin II type 1 receptors.  Angiotensin II receptor antagonists that have existed in the pharmaceutical market have had higher affinities for angiotensin II type 1 receptors (AT R) over type 2 receptors.  AT R are not involved with nociception.  AT R antagonists have been mostly used for the treatment of hypertension.

Oxandrolone: Oxandrolone (brand names Oxandrin, Anavar, Lonavar, others), is a synthetic, orally active anabolic-androgenic steroid (AAS) that first became available as a prescription drug in the United States in 1964.  It is a 17α-methylated derivative of dihydrotestosterone (DHT) that has an oxygen atom in place of the carbon at the 2 position.
