Jmol
Jmol is computer software for molecular modelling chemical structures in 3-dimensions. Jmol returns a 3D representation of a molecule that may be used as a teaching tool, or for research e.g. in chemistry and biochemistry. It is written in the programming language Java, so it can run on the operating systems Windows, macOS, Unix, if Java is installed, it is free and open-source software released under a GNU Lesser General Public License version 2.0. A standalone application and a software development kit exist that can be integrated into other Java applications, such as Bioclipse and Taverna. A popular feature is an applet that can be integrated into web pages to display molecules in a variety of ways. For example, molecules can be displayed as ball-and-stick models, space-filling models, ribbon diagrams, etc. Jmol supports a wide range of chemical file formats, including Protein Data Bank, Crystallographic Information File, MDL Molfile, Chemical Markup Language. There is a JavaScript-only version, JSmol, that can be used on computers with no Java.
The Jmol applet, among other abilities, offers an alternative to the Chime plug-in, no longer under active development. While Jmol has many features that Chime lacks, it does not claim to reproduce all Chime functions, most notably, the Sculpt mode. Chime requires plug-in installation and Internet Explorer 6.0 or Firefox 2.0 on Microsoft Windows, or Netscape Communicator 4.8 on Mac OS 9. Jmol operates on a wide variety of platforms. For example, Jmol is functional in Mozilla Firefox, Internet Explorer, Google Chrome, Safari.

Food and Drug Administration
The Food and Drug Administration is a federal agency of the United States Department of Health and Human Services, one of the United States federal executive departments. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, dietary supplements and over-the-counter pharmaceutical drugs, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices, animal foods & feed and veterinary products; as of 2017, 3/4th of the FDA budget is paid by people who consume pharmaceutical products, due to the Prescription Drug User Fee Act. The FDA was empowered by the United States Congress to enforce the Federal Food and Cosmetic Act, which serves as the primary focus for the Agency; these include regulating lasers, cellular phones and control of disease on products ranging from certain household pets to sperm donation for assisted reproduction. The FDA is led by the Commissioner of Food and Drugs, appointed by the President with the advice and consent of the Senate.
The Commissioner reports to the Secretary of Human Services. Scott Gottlieb, M. D. is the current commissioner, who took over in May 2017. The FDA has its headquarters in Maryland; the agency has 223 field offices and 13 laboratories located throughout the 50 states, the United States Virgin Islands, Puerto Rico. In 2008, the FDA began to post employees to foreign countries, including China, Costa Rica, Chile and the United Kingdom. In recent years, the agency began undertaking a large-scale effort to consolidate its 25 operations in the Washington metropolitan area, moving from its main headquarters in Rockville and several fragmented office buildings to the former site of the Naval Ordnance Laboratory in the White Oak area of Silver Spring, Maryland; the site was renamed from the White Oak Naval Surface Warfare Center to the Federal Research Center at White Oak. The first building, the Life Sciences Laboratory, was dedicated and opened with 104 employees on the campus in December 2003. Only one original building from the naval facility was kept.
All other buildings are new construction. The project is slated to be completed by 2021, assuming future Congressional funding While most of the Centers are located in the Washington, D. C. area as part of the Headquarters divisions, two offices – the Office of Regulatory Affairs and the Office of Criminal Investigations – are field offices with a workforce spread across the country. The Office of Regulatory Affairs is considered the "eyes and ears" of the agency, conducting the vast majority of the FDA's work in the field. Consumer Safety Officers, more called Investigators, are the individuals who inspect production and warehousing facilities, investigate complaints, illnesses, or outbreaks, review documentation in the case of medical devices, biological products, other items where it may be difficult to conduct a physical examination or take a physical sample of the product; the Office of Regulatory Affairs is divided into five regions, which are further divided into 20 districts. Districts are based on the geographic divisions of the federal court system.
Each district comprises a main district office and a number of Resident Posts, which are FDA remote offices that serve a particular geographic area. ORA includes the Agency's network of regulatory laboratories, which analyze any physical samples taken. Though samples are food-related, some laboratories are equipped to analyze drugs and radiation-emitting devices; the Office of Criminal Investigations was established in 1991 to investigate criminal cases. Unlike ORA Investigators, OCI Special Agents are armed, don't focus on technical aspects of the regulated industries. OCI agents pursue and develop cases where individuals and companies have committed criminal actions, such as fraudulent claims, or knowingly and willfully shipping known adulterated goods in interstate commerce. In many cases, OCI pursues cases involving Title 18 violations, in addition to prohibited acts as defined in Chapter III of the FD&C Act. OCI Special Agents come from other criminal investigations backgrounds, work with the Federal Bureau of Investigation, Assistant Attorney General, Interpol.
OCI receives cases from a variety of sources—including ORA, local agencies, the FBI—and works with ORA Investigators to help develop the technical and science-based aspects of a case. OCI is a smaller branch; the FDA works with other federal agencies, including the Department of Agriculture, Drug Enforcement Administration and Border Protection, Consumer Product Safety Commission. Local and state government agencies work with the FDA to provide regulatory inspections and enforcement action; the FDA regulates more than US$2.4 trillion worth of consumer goods, about 25% of consumer expenditures in the United States. This includes $466 billion in food sales, $275 billion in drugs, $60 billion in cosmetics and $18 billion in vitamin supplements. Much of these expenditures are for goods imported into the United States; the FDA's federal budget request for fiscal year 2012 totaled $4.36 billion, while the proposed 2014 budget is $4.7 billion. About $2 billion of this budget is generated by user fees.

Convention on Psychotropic Substances
The Convention on Psychotropic Substances of 1971 is a United Nations treaty designed to control psychoactive drugs such as amphetamine-type stimulants, barbiturates and psychedelics signed in Vienna, Austria on 21 February 1971. The Single Convention on Narcotic Drugs of 1961 did not ban the many newly discovered psychotropics, since its scope was limited to drugs with cannabis and opium-like effects. During the 1960s such drugs became available, government authorities opposed this for numerous reasons, arguing that along with negative health effects, drug use led to lowered moral standards; the Convention, which contains import and export restrictions and other rules aimed at limiting drug use to scientific and medical purposes, came into force on 16 August 1976. As of 2013, 183 member states are Parties to the treaty. Many laws have been passed to implement the Convention, including the U. S. Psychotropic Substances Act, the UK Misuse of Drugs Act 1971, the Canadian Controlled Drugs and Substances Act.
Adolf Lande, under the direction of the United Nations Office of Legal Affairs, prepared the Commentary on the Convention on Psychotropic Substances. The Commentary, published in 1976, is an invaluable aid to interpreting the treaty and constitutes a key part of its legislative history. Provisions to end the international trafficking of drugs covered by this Convention are contained in the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances; this treaty, signed in 1988, regulates precursor chemicals to drugs controlled by the Single Convention and the Convention on Psychotropic Substances. It strengthens provisions against money laundering and other drug-related crimes. International drug control began with the 1912 International Opium Convention, a treaty which adopted import and export restrictions on the opium poppy's psychoactive derivatives. Over the next half-century, several additional treaties were adopted under League of Nations auspices expanding the list of controlled substances to encompass cocaine and other drugs and granting the Permanent Central Opium Board power to monitor compliance.
After the United Nations was formed in 1945, those enforcement functions passed to the UN. In 1961, a conference of plenipotentiaries in New York adopted the Single Convention on Narcotic Drugs, which consolidated the existing drug control treaties into one document and added Cannabis to the list of prohibited plants. In order to appease the pharmaceutical interests, the Single Convention's scope was limited to the list of drugs enumerated in the Schedules annexed to the treaty and to those drugs determined to have similar effects. During the 1960s, drug use increased in Western developed nations. Young people began using hallucinogenic and other drugs on a widespread scale that has continued to the present. In many jurisdictions, police had no laws under which to prosecute users and traffickers of these new drugs. S. until 1967. In 1968, "eeply concerned at reports of serious damage to health being caused by LSD and similar hallucinogenic substances," the United Nations Economic and Social Council passed a resolution calling on nations to limit the use of such drugs to scientific and medical purposes and to impose import and export restrictions.
That year, the UN General Assembly requested that ECOSOC call upon its Commission on Narcotic Drugs to "give urgent attention to the problem of the abuse of the psychotropic substances not yet under international control, including the possibility of placing such substances under international control". Circa 1969, with use of stimulants growing, ECOSOC noted with considerable consternation that the Commission "was unable to reach agreement on the applicability of the Single Convention on Narcotic Drugs, 1961 to these substances"; the language of the Single Convention and its legislative history precluded any interpretation that would allow international regulation of these drugs under that treaty. A new convention, with a broader scope, would be required in order to bring those substances under control. Using the Single Convention as a template, the Commission prepared a draft convention, forwarded to all UN member states; the Secretary-General of the United Nations scheduled a conference for early 1971 to finalize the treaty.
Meanwhile, countries had begun passing legislation to implement the draft treaty. In 1969, Canada added Part IV to its Food and Drugs Act, placing a set of "restricted substances," including LSD, DMT, MDA, under federal control. In 1970, the United States revamped its existing drug control laws by enacting the Controlled Substances Act. In 1971, the United Kingdom passed the Misuse of Drugs Act 1971. A host of other nations followed suit. A common feature shared by most implementing legislation is the establishment of several classes or Schedules of controlled substances to the Single Convention and the Convention on Psychotropic Substances, so that compliance with international law can be assured by placing a drug into the appropriate Schedule; the conference convened on 11 January 1971. Nations split based on their interests. According to a Senate of Canada report, "One group included developed nations with powerful pharmaceutical industries and active psychotropics markets... The other group consisted of developing states...with few psychotropic manufacturing facilities".
The organic drugmaking states that had suffered economically from the Single Convention's restrictions on cannabis and opiu
Japan
Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south; the kanji that make up Japan's name mean "sun origin", it is called the "Land of the Rising Sun". Japan is a stratovolcanic archipelago consisting of about 6,852 islands; the four largest are Honshu, Hokkaido and Shikoku, which make up about ninety-seven percent of Japan's land area and are referred to as home islands. The country is divided into 47 prefectures in eight regions, with Hokkaido being the northernmost prefecture and Okinawa being the southernmost one; the population of 127 million is the world's tenth largest. 90.7 % of people live in cities. About 13.8 million people live in the capital of Japan. The Greater Tokyo Area is the most populous metropolitan area in the world with over 38 million people. Archaeological research indicates; the first written mention of Japan is in Chinese history texts from the 1st century AD.
Influence from other regions China, followed by periods of isolation from Western Europe, has characterized Japan's history. From the 12th century until 1868, Japan was ruled by successive feudal military shōguns who ruled in the name of the Emperor. Japan entered into a long period of isolation in the early 17th century, ended in 1853 when a United States fleet pressured Japan to open to the West. After nearly two decades of internal conflict and insurrection, the Imperial Court regained its political power in 1868 through the help of several clans from Chōshū and Satsuma – and the Empire of Japan was established. In the late 19th and early 20th centuries, victories in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism; the Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the Japanese surrender. Since adopting its revised constitution on May 3, 1947, during the occupation led by SCAP, the sovereign state of Japan has maintained a unitary parliamentary constitutional monarchy with an Emperor and an elected legislature called the National Diet.
Japan is a member of the ASEAN Plus mechanism, UN, the OECD, the G7, the G8, the G20, is considered a great power. Its economy is the world's third-largest by nominal GDP and the fourth-largest by purchasing power parity, it is the world's fourth-largest exporter and fourth-largest importer. Japan benefits from a skilled and educated workforce. Although it has renounced its right to declare war, Japan maintains a modern military with the world's eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a developed country with a high standard of living and Human Development Index, its population enjoys the highest life expectancy and third lowest infant mortality rate in the world, but is experiencing issues due to an aging population and low birthrate. Japan is renowned for its historical and extensive cinema, influential music industry, video gaming, rich cuisine and its major contributions to science and modern technology; the Japanese word for Japan is 日本, pronounced Nihon or Nippon and means "the origin of the sun".
The character nichi means "sun" or "day". The compound therefore means "origin of the sun" and is the source of the popular Western epithet "Land of the Rising Sun"; the earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, the Old Book of Tang. At the end of the seventh century, a delegation from Japan requested that Nihon be used as the name of their country; this name may have its origin in a letter sent in 607 and recorded in the official history of the Sui dynasty. Prince Shōtoku, the Regent of Japan, sent a mission to China with a letter in which he called himself "the Emperor of the Land where the Sun rises"; the message said: "Here, I, the emperor of the country where the sun rises, send a letter to the emperor of the country where the sun sets. How are you". Prior to the adoption of Nihon, other terms such as Yamato and Wakoku were used; the term Wa is a homophone of Wo 倭, used by the Chinese as a designation for the Japanese as early as the third century Three Kingdoms period.
Another form of Wa, Wei in Chinese) was used for an early state in Japan called Nakoku during the Han dynasty. However, the Japanese disliked some connotation of Wa 倭, it was therefore replaced with the substitute character Wa, meaning "togetherness, harmony"; the English word Japan derives from the historical Chinese pronunciation of 日本. The Old Mandarin or early Wu Chinese pronunciation of Japan was recorded by Marco Polo as Cipangu. In modern Shanghainese, a Wu dialect, the pronunciation of characters 日本; the old Malay word for Japan, Japun or Japang, was borrowed from a southern coastal Chinese dialect Fukienese or Ningpo – and this Malay word was encountered by Portuguese traders in Southeast Asia in the 16th century. These Early Portuguese traders brought the word
Drug Enforcement Administration
The Drug Enforcement Administration is a United States federal law enforcement agency under the United States Department of Justice, tasked with combating drug smuggling and distribution within the United States. The DEA is the lead agency for domestic enforcement of the Controlled Substances Act, sharing concurrent jurisdiction with the Federal Bureau of Investigation and Customs Enforcement, U. S. Customs and Border Protection, the Department of Homeland Security, it has sole responsibility for coordinating and pursuing US drug investigations both domestic and abroad. The Drug Enforcement Administration was established on July 1, 1973, by Reorganization Plan No. 2 of 1973, signed by President Richard Nixon on July 28. It proposed the creation of a single federal agency to enforce the federal drug laws as well as consolidate and coordinate the government's drug control activities. Congress accepted the proposal; as a result, the Bureau of Narcotics and Dangerous Drugs, the Office of Drug Abuse Law Enforcement.
From the early 1970s, DEA headquarters was located at 1405 I Street NW in downtown Washington, D. C. With the overall growth of the agency in the 1980s and a concurrent growth in the headquarters staff, DEA began to search for a new headquarters location. However, then-Attorney General Edwin Meese determined that the headquarters had to be located in close proximity to the Attorney General's office. Thus, in 1989, the headquarters relocated to 600–700 Army-Navy Drive in the Pentagon City area of Arlington, near the Metro station with the same name. On April 19, 1995, Timothy McVeigh attacked the Alfred P. Murrah Federal Building in Oklahoma City because it housed regional offices for the FBI, Bureau of Alcohol, Tobacco and Explosives, DEA, all of which had carried out raids that he viewed as unjustified intrusions on the rights of the people. Subsequently, the DEA headquarters complex was classified as a Level IV installation under United States federal building security standards, meaning it was to be considered a high-risk law enforcement target for terrorists.
Security measures include hydraulic steel roadplates to enforce standoff distance from the building, metal detectors, guard stations. In February 2003, the DEA established a Digital Evidence Laboratory within its Office of Forensic Sciences; the DEA is headed by an Administrator of Drug Enforcement appointed by the President of the United States and confirmed by the U. S. Senate; the Administrator reports to the Attorney General through the Deputy Attorney General. The Administrator is assisted by a Deputy Administrator, the Chief of Operations, the Chief Inspector, three Assistant Administrators. Other senior staff include the Chief Counsel; the Administrator and Deputy Administrator are the only presidentially-appointed personnel in the DEA. DEA's headquarters is located in Virginia across from the Pentagon, it maintains its own DEA Academy located on the Marine Corps Base Quantico at Quantico, Virginia along with the FBI Academy. It maintains 21 domestic field divisions with 221 field offices and 92 foreign offices in 70 countries.
With a budget exceeding $2 billion, DEA employs over 10,800 people, including over 4,600 Special Agents and 800 Intelligence Analysts. Becoming a Special Agent or Intelligence Analyst with the DEA is a competitive process.

DEA agents' starting salary is $49,746–$55,483. After four years working as an agent, the salary jumps to above $92,592. After receiving a conditional offer of employment, recruits must complete a 18-week rigorous training which includes lessons in firearms proficiency, weapons safety, tactical shooting, deadly-force decision training. In order to graduate, students must maintain an academic average of 80 percent on academic examinations, pass the firearms-qualification test demonstrate leadership and sound decision-making in practical scenarios, pass rigorous physical-task tests. Upon graduation, recruits earn the title of DEA Special Agent; the DEA excludes from consideration job applicants who have a history of any use of narcotics or illicit drugs. Investigation incl
Hypnotic
Hypnotic or soporific drugs known as sleeping pills, are a class of psychoactive drugs whose primary function is to induce sleep and to be used in the treatment of insomnia, or for surgical anesthesia. This group is related to sedatives. Whereas the term sedative describes drugs that serve to calm or relieve anxiety, the term hypnotic describes drugs whose main purpose is to initiate, sustain, or lengthen sleep; because these two functions overlap, because drugs in this class produce dose-dependent effects they are referred to collectively as sedative-hypnotic drugs. Hypnotic drugs are prescribed for insomnia and other sleep disorders, with over 95% of insomnia patients being prescribed hypnotics in some countries. Many hypnotic drugs are habit-forming and, due to a large number of factors known to disturb the human sleep pattern, a physician may instead recommend changes in the environment before and during sleep, better sleep hygiene, the avoidance of caffeine or other stimulating substances, or behavioral interventions such as cognitive behavioral therapy for insomnia before prescribing medication for sleep.
When prescribed, hypnotic medication should be used for the shortest period of time necessary. Among individuals with sleep disorders, 13.7% are taking or prescribed nonbenzodiazepines, while 10.8% are taking benzodiazepines, as of 2010. Early classes of drugs, such as barbiturates, have fallen out of use in most practices but are still prescribed for some patients. In children, prescribing hypnotics is not yet acceptable unless used to treat night terrors or somnambulism. Elderly people are more sensitive to potential side effects of daytime fatigue and cognitive impairments, a meta-analysis found that the risks outweigh any marginal benefits of hypnotics in the elderly. A review of the literature regarding benzodiazepine hypnotics and Z-drugs concluded that these drugs can have adverse effects, such as dependence and accidents, that optimal treatment uses the lowest effective dose for the shortest therapeutic time period, with gradual discontinuation in order to improve health without worsening of sleep.
Falling outside the above-mentioned categories, the neuro-hormone melatonin has a hypnotic function. Hypnotica was a class of somniferous drugs and substances tested in medicine of the 1890s and including: Urethan, Methylal, paraldehyde, Hypnon and Ohloralamid or Chloralimid. Research about using medications to treat insomnia evolved throughout the last half of the 20th century. Treatment for insomnia in psychiatry dates back to 1869 when chloral hydrate was first used as a soporific. Barbiturates emerged as the first class of drugs that emerged in the early 1900s, after which chemical substitution allowed derivative compounds. Although the best drug family at the time they were dangerous in overdose and tended to cause physical and psychological dependence. During the 1970s, quinazolinones and benzodiazepines were introduced as safer alternatives to replace barbiturates. Benzodiazepines are not without their drawbacks. Questions have been raised as to. Nonbenzodiazepines are the most recent development.
Although it's clear that they are less toxic than their predecessors, comparative efficacy over benzodiazepines have not been established. Without longitudinal studies, it is hard to determine. Other sleep remedies that may be considered "sedative-hypnotics" exist. Examples of these include mirtazapine, clonidine and the over-the-counter sleep aid diphenhydramine. Off-label sleep remedies are useful when first-line treatment is unsuccessful or deemed unsafe. Barbiturates are drugs that act as central nervous system depressants, can therefore produce a wide spectrum of effects, from mild sedation to total anesthesia, they are effective as anxiolytics and anticonvulsalgesic effects. They have dependence liability, both psychological. Barbiturates have now been replaced by benzodiazepines in routine medical practice – for example, in the treatment of anxiety and insomnia – because benzodiazepines are less dangerous in overdose. However, barbiturates are still used in general anesthesia, for epilepsy, assisted suicide.
Barbiturates are derivatives of barbituric acid. The principal mechanism of action of barbiturates is believed to be positive allosteric modulation of GABAA receptors. Examples include amobarbital, phenobarbital and sodium thiopental. Quinazolinones are a class of drugs which function as hypnotic/sedatives that contain a 4-quinazolinone core, their use has been proposed in the treatment of cancer. Examples of quinazolinones include cloroqualone, etaqualone, mebroqualone and methaqualone. Benzodiaz
Route of administration
A route of administration in pharmacology and toxicology is the path by which a drug, poison, or other substance is taken into the body. Routes of administration are classified by the location at which the substance is applied. Common examples include intravenous administration. Routes can be classified based on where the target of action is. Action may be enteral, or parenteral. Route of administration and dosage form are aspects of drug delivery. Routes of administration are classified by application location; the route or course the active substance takes from application location to the location where it has its target effect is rather a matter of pharmacokinetics. Exceptions include the transdermal or transmucosal routes, which are still referred to as routes of administration; the location of the target effect of active substances are rather a matter of pharmacodynamics. An exception is topical administration, which means that both the application location and the effect thereof is local. Topical administration is sometimes defined as both a local application location and local pharmacodynamic effect, sometimes as a local application location regardless of location of the effects.
Administration through the gastrointestinal tract is sometimes termed enteral or enteric administration. Enteral/enteric administration includes oral and rectal administration, in the sense that these are taken up by the intestines. However, uptake of drugs administered orally may occur in the stomach, as such gastrointestinal may be a more fitting term for this route of administration. Furthermore, some application locations classified as enteral, such as sublingual and sublabial or buccal, are taken up in the proximal part of the gastrointestinal tract without reaching the intestines. Enteral administration can be used for systemic administration, as well as local, such as in a contrast enema, whereby contrast media is infused into the intestines for imaging. However, for the purposes of classification based on location of effects, the term enteral is reserved for substances with systemic effects. Many drugs as tablets, capsules, or drops are taken orally. Administration methods directly into the stomach include those by gastric feeding tube or gastrostomy.
Substances may be placed into the small intestines, as with a duodenal feeding tube and enteral nutrition. Enteric coated tablets are designed to dissolve in the intestine, not the stomach, because the drug present in the tablet causes irritation in the stomach; the rectal route is an effective route of administration for many medications those used at the end of life. The walls of the rectum absorb many medications and effectively. Medications delivered to the distal one-third of the rectum at least avoid the "first pass effect" through the liver, which allows for greater bio-availability of many medications than that of the oral route. Rectal mucosa is vascularized tissue that allows for rapid and effective absorption of medications. A suppository is a solid dosage form. In hospice care, a specialized rectal catheter, designed to provide comfortable and discreet administration of ongoing medications provides a practical way to deliver and retain liquid formulations in the distal rectum, giving health practitioners a way to leverage the established benefits of rectal administration.
The parenteral route is any route, not enteral. Parenteral administration can be performed by injection, that is, using a needle and a syringe, or by the insertion of an indwelling catheter. Locations of application of parenteral administration include: central nervous systemepidural, e.g. epidural anesthesia intracerebral direct injection into the brain. Used in experimental research of chemicals and as a treatment for malignancies of the brain; the intracerebral route can interrupt the blood brain barrier from holding up against subsequent routes. Intracerebroventricular administration into the ventricular system of the brain. One use is as a last line of opioid treatment for terminal cancer patients with intractable cancer pain. Epicutaneous, it can be used both for local effect as in allergy testing and typical local anesthesia, as well as systemic effects when the active substance diffuses through skin in a transdermal route. Sublingual and buccal medication administration is a way of giving someone medicine orally.
Sublingual administration is. The word "sublingual" means "under the tongue." Buccal administration involves placement of the drug between the cheek. These medications can come in the form of films, or sprays. Many drugs are designed for sublingual administration, including cardiovascular drugs, barbiturates, opioid analgesics with poor gastrointestinal bioavailability and vitamins and minerals. Extra-amniotic administration, between the endometrium and fetal membranes nasal administration (th
