Nicotinamide mononucleotide, commonly abbreviated NMN, is a naturally occurring nucleotide. Its structure combines a nicotinamide ring with a ribose sugar and a phosphate group. The compound appears in cells across many organisms as an intermediate in the production of nicotinamide adenine dinucleotide, or NAD+. Because NMN sits close to NAD+ in metabolism, it has drawn interest in biochemistry and aging research. The molecule is not a dietary essential nutrient in the classical sense, and its presence in food is generally low and variable.
NAD+ serves as a coenzyme in redox reactions and as a substrate for enzymes involved in DNA repair and cellular signaling. In the salvage pathway, nicotinamide is converted to NMN by the enzyme NAMPT. NMN is then converted to NAD+ by NMNAT enzymes. A separate route links nicotinamide riboside to NMN through phosphorylation. These pathways maintain NAD+ levels, which can decline with age or metabolic stress in some tissues. The relative contribution of circulating NMN to tissue NAD+ remains an active area of study.
Research on NMN includes cell studies, animal experiments, and a growing number of human trials. Many early findings come from mice, where changes in NAD+ levels and metabolic markers have been reported. Human data are more limited, and questions remain about effective routes of administration, tissue distribution, and long-term effects. Some trials measure NAD+ in blood or tissue, while others assess physical function or metabolic outcomes. Regulatory status differs between countries, and NMN is not universally approved as a dietary supplement or therapeutic agent.
Dietary sources of NMN include small amounts in certain vegetables, fruits, and other foods, although exact values vary by sample and method. Endogenous NMN concentrations are tightly regulated and often low, making measurement in blood or tissues technically demanding. After oral intake, NMN is thought to be rapidly metabolized in the intestine and liver, and intact NMN may not reach all tissues at high levels. Some rodent studies report increases in tissue NAD+ after oral NMN, while human data remain limited and sometimes rely on blood NAD+ metabolites rather than direct tissue measures.
Research on NMN has focused on aging, metabolic regulation, exercise capacity, and insulin sensitivity, but findings are preliminary. Many human trials are small, short in duration, and use different endpoints, which complicates comparison across studies. No national regulator has approved NMN as a therapeutic drug for any indication. In some countries it is sold as a supplement or research chemical, while other jurisdictions have questioned its status under food or supplement laws. Claims about extending human lifespan or reversing aging are not supported by established clinical evidence.
Nicotinamide mononucleotide, abbreviated NMN, is a naturally occurring nucleotide found in the cells of many organisms, including bacteria, plants, and mammals. Its structure consists of a nicotinamide ring attached to a ribose-phosphate group. NMN functions as an intermediate in the NAD+ salvage pathway, a recycling route that regenerates nicotinamide adenine dinucleotide. The enzyme nicotinamide phosphoribosyltransferase produces NMN from nicotinamide and phosphoribosyl pyrophosphate. A second enzyme, NMN adenylyltransferase, then converts NMN into NAD+.

NMN occurs in many living systems, including bacteria, yeast, plants, and mammals. Dietary sources are present in foods such as edamame, avocado, broccoli, and various meats, but amounts vary widely and are generally lower than those used in research settings. Laboratory production often relies on enzymatic synthesis or chemical phosphorylation of nicotinamide riboside, and commercial material is typically supplied as a white to off-white powder. Because NMN is hygroscopic and sensitive to heat, moisture, and pH extremes, its handling requires care to preserve identity and purity. Aqueous preparation should be done with attention to pH and temperature to limit hydrolysis.
Nicotinamide mononucleotide, abbreviated NMN, is a naturally occurring nucleotide found in cells. Its structure consists of a nicotinamide ring linked to ribose phosphate, and the compound serves as an intermediate in the salvage pathway for nicotinamide adenine dinucleotide, or NAD+. In this pathway, nicotinamide phosphoribosyltransferase converts nicotinamide and phosphoribosyl pyrophosphate into NMN, after which NMN adenylyltransferase attaches an adenylate group to produce NAD+. Because NAD+ participates in redox reactions and signaling, NMN occupies a central position in cellular metabolism. The molecule is distinct from nicotinamide riboside, though the two are related in NAD+ precursor research.
Beyond its intracellular synthesis, NMN can be taken up from the extracellular environment, although the routes are still debated. Some evidence points to direct transport into cells through specific transporters, while other work suggests dephosphorylation to nicotinamide riboside followed by cellular uptake. Once inside, NMN can be converted to NAD+ by NMN adenylyltransferases; the relative contribution of these routes may differ by tissue, species, and experimental conditions. Researchers continue to investigate which mechanisms dominate in intact organisms and how they affect measured NAD+ levels. Direct measurement in tissues remains technically challenging because NMN can be rapidly metabolized during sample collection.
The term NMN commonly refers to the beta isomer, in which the nicotinamide group is attached to the ribose through a beta-glycosidic bond. Commercial material may be supplied as the free acid or as a salt, such as a sodium salt, which affects molecular weight and water solubility. Related compounds include nicotinamide riboside and NAD+ itself, but these are distinct molecules with different formulas and cellular handling. Laboratory research often uses the beta form because it matches the naturally occurring configuration found in biological systems.
Small amounts of NMN occur in some foods, including certain vegetables, fruits, and animal products, though the quantities are generally low and variable. Human cells also synthesize NMN internally from nicotinamide and other precursors. Research interest increased after studies examined whether raising NAD+ levels affects metabolism and aging-related pathways in animals. Evidence in humans remains limited and mixed for many outcomes, and questions about effective absorption, tissue delivery, and long-term effects are still open. Regulatory status differs by country, with some markets treating NMN as a supplement ingredient and others restricting its sale.
To address the destruction, a commission created by the law of February 12, 1872, was tasked with reconstructing Parisian civil records before 1860. This work relied on cross-referencing family papers (notices in particular), notarial deeds, and records of parish and civil acts compiled before 1871 by archivists such as Auguste Jal, especially for prominent individuals. However, the main sources used were Catholic registers from 1793 to 1860, preserved in parishes and had not been burned. Accompanied by alphabetical index cards for searching, the reconstructed records were produced in duplicate through three distinct methods:
Various bacteria Fungi Phylogenetically distant plants Nematodes like C. elegans Insects Fish Birds Various rodents Lagomorphs like rabbits Mammals (including humans) Distribution within (higher) organisms also appears to be ubiquitous as it has been found in the:
Orenetide (INNTooltip International Nonproprietary Name; developmental code name BP101, proposed brand names Libicore and Desirix), also known as Thr-Lys-Pro-Arg-Pro or as so-called "female Viagra", is a synthetic small peptide drug which is under development for the treatment of female sexual dysfunction, or more specifically hypoactive sexual desire disorder (HSDD). It is taken intranasally as a nasal spray. The mechanism of action of orenetide has not been fully elucidated and is unknown. It was inactive at a panel of 98 G protein-coupled receptors (GPCRs), including serotonin, dopamine, and melanocortin receptors, among others. However, at high concentrations in vitro, it inhibited selected GABAA receptors, which may be involved in its effects. Relatedly, it has been labeled in some sources as a "GABAA receptor antagonist". The drug produces pro-sexual effects in rodents, with these effects appearing to be mediated in the medial preoptic area. It is described as a potential first-in-class medication. The drug was originated by Ivix and is under development by Ovoca Bio. As of January 2021, it is in the preregistration phase of development. In August 2023, it was announced that orenetide had failed to show efficacy for sexual desire or sexual distress in a large dose-ranging phase 2 clinical trial for treatment of HSDD. Shares of Ovoca Bio fell by as much as 82% following the announcement. Ovoca Bio is Ireland-based and orenetide has been developed in Australia, New Zealand, and Russia.
Some hematomas are visible under the surface of the skin (commonly called bruises) or possibly felt as masses or lumps. Lumps may be caused by the limitation of the blood to a sac, subcutaneous or intramuscular tissue space isolated by fascial planes. This is an anatomical feature that helps prevent injuries from causing massive blood loss. In most cases a hematoma as a sac of blood eventually dissolves; however, in some cases it may continue to grow due to blood seepage or show no change. If the sac of blood does not disappear, then it may need to be surgically cleaned out or repaired. The slow process of reabsorption of hematomas can allow the broken down blood cells and hemoglobin pigment to move in the connective tissue. For example, an injury to the base of the thumb might cause a hematoma that moves slowly throughout the finger over the course of a week. Gravity is the main determinant of this process. Hematomas on articulations can reduce mobility of a member and present roughly the same symptoms as a fracture. In most cases, movement and exercise of the affected muscle is the best way to introduce the collection back into the bloodstream.

The short features a cover of "Pure Imagination" from Willy Wonka & the Chocolate Factory, sung by Fiona Apple. It was named one of the worst advertisements of 2013 by The Wall Street Journal. In 2011, Chipotle created the "Farm Team", which is a rewards program available only by invitation from restaurant managers. The Farm Team members have access to a special Chipotle website, where members can earn rewards, i.e. free food and T-shirts. The site offers members to, "learn where Chipotle's food comes from, take quizzes and polls, play games and watch videos about the company". In April 2014, the Farm Team program was shut down. Chipotle sponsors Team Garmin-Barracuda (formerly Team Garmin-Chipotle, Team Garmin-Slipstream, Team Garmin-Transitions and Team Garmin-Cervélo) of the International Cycling Union, and is an official team partner of the Boston Celtics, and the Boston Bruins. In June 2009, Chipotle sponsored free screenings of Food, Inc., a film that criticizes the corporate food industry. Founder Steve Ells stated that he hoped the film would make customers appreciate Chipotle's Food With Integrity policy. From May until September 2009, Chipotle ran a contest on mychipotle.com, a microsite which had a competition for the best user-created audio and video presentations about different combinations of ingredients. In July 2010, Chipotle began a campaign to support healthier lunch alternatives for students, in which money will be donated to The Lunch Box program based on how many spam Emails consumers forward to a company Email address.
== History == 2C-B was first synthesized and evaluated by American chemist Alexander Shulgin in 1974. He described the properties and effects of 2C-B in humans, along with those of 2C-D, in the scientific literature in 1975. Shulgin proposed 2C-B and 2C-D for use in psychedelic-assisted psychotherapy. However, it was reportedly abandoned for such purposes due to gastrointestinal side effects and lack of entactogenic effects. 2C-B was Shulgin's favorite psychedelic of his own creations, though he has said that he only tried it a few times.
== Bulk properties == Radium is the heaviest known alkaline earth metal and is the only radioactive member of its group. Its physical and chemical properties most closely resemble its lighter congener, barium. Pure radium is a volatile, lustrous silvery-white metal, even though its lighter congeners calcium, strontium, and barium have a slight yellow tint. Radium's lustrous surface rapidly becomes black upon exposure to air, likely due to the formation of radium nitride (Ra3N2). Its melting point is either 700 °C (1,292 °F) or 960 °C (1,760 °F) and its boiling point is 1,737 °C (3,159 °F); however, this is not well established. Both of these values are slightly lower than those of barium, confirming periodic trends down the group 2 elements. Like barium and the alkali metals, radium crystallizes in the body-centered cubic structure at standard temperature and pressure: the radium–radium bond distance is 514.8 picometers. Radium has a density of 5.5 g/cm3, higher than that of barium, and the two elements have similar crystal structures (bcc at standard temperature and pressure).
== History == Relugolix was first described in 2004. It superseded sufugolix (developmental code name TAK-013), which was developed by the same researchers. Relugolix was approved for the treatment of uterine fibroids in Japan in January 2019. It was the second orally active GnRH antagonist to be introduced for medical use, following elagolix (brand name Orilissa) in July 2018. Relugolix was approved for the treatment of prostate cancer in the United States on 18 December 2020. The FDA approved relugolix based on evidence from a clinical trial (NCT03085095) of 930 participants 48 to 97 years old with advanced prostate cancer. The trial was conducted at 155 sites in the United States, Canada, and countries in South America, Europe and the Asia Pacific region. All participants in the trial had advanced prostate cancer. Participants were randomly assigned to receive either one relugolix tablet daily (on the first day they received three tables) or an active control (leuprolide acetate) which was given as an injection under the skin every three months. The participants and healthcare providers were aware of which treatment was being given. The treatment lasted for 48 weeks. The efficacy of relugolix was assessed by the percentage of participants who achieved and maintained low testosterone level equal to castration.

Periodic acid-Schiff is a histology special stain used to mark carbohydrates (glycogen, glycoprotein, proteoglycans). PAS is commonly used on liver tissue where glycogen deposits are made which is done in efforts to distinguish different types of glycogen storage diseases. PAS is important because it can detect glycogen granules found in tumors of the ovaries and pancreas of the endocrine system, as well as in the bladder and kidneys of the renal system. Basement membranes can also show up in a PAS stain and can be important when diagnosing renal disease. Due to the high volume of carbohydrates within the cell wall of hyphae and yeast forms of fungi, the Periodic acid -Schiff stain can help locate these species inside tissue samples of the human body.
The 12 Minute Walk Test (12MWT) can be used to determine "second wind," which requires a treadmill (no incline), heart rate monitor, stopwatch, pain scale, and that the patient has rested for 30 minutes before the test to ensure that "second wind" has stopped (that is, that increased ATP production primarily from free fatty acids has returned to resting levels). Electromyography (EMG) may show normal or myopathic results (short duration, polyphasic, small amplitude MUAPs). Before exercise, a minority of GSD-V patients show myopathic results (5/25 patients); whereas after 5 minutes of high-intensity isometric exercise, the majority showed myopathic results (22/25 patients). The myopathic results were a decrease in CMAP amplitude, which was evident immediately after exercise and, after a plateau phase of a few minutes, reached its maximum after 30 minutes.
== Ideology == SPUSA argues that socialism can only come through social revolution. SPUSA tendencies include both democratic socialism, for a gradual transformation of society, and revolutionary socialism, for a rapid transformation following a slow "socialist transformation from below" through radically democratic "people's organizations". SPUSA describes socialism as a radically democratic system which "places people's lives under their own control—a classless, feminist, socialist society free of racism, sexism, homophobia or transphobia," and in which "the people own and control the means of production and distribution through democratically controlled public agencies, cooperatives, or other collective groups"; "full employment is realized for everyone who wants to work"; "workers have the right to form unions freely, and to strike and engage in other forms of job actions"; and "production of society is used for the benefit of all humanity, not for the private profit of a few." Socialist Party candidates support expanding social spending and social ownership of capital. In 2009, Greg Pason's proposals included socializing the United States health care system, a steeply graduated income tax, universal rent control and the elimination of all educational debts and tuition fees. In 1997, Pason called auto insurance "a regressive tax against working people". Moore was also vocal of his support for socialized medicine. Moore supported economic democracy through social ownership and workers' control of reigning industrial and financial institutions.
== Uses == Salts have long had a wide variety of uses and applications. Many minerals are ionic. Humans have processed common salt (sodium chloride) for over 8000 years, using it first as a food seasoning and preservative, and now also in manufacturing, agriculture, water conditioning, for de-icing roads, and many other uses. Many salts are so widely used in society that they go by common names unrelated to their chemical identity. Examples of this include borax, calomel, milk of magnesia, muriatic acid, oil of vitriol, saltpeter, and slaked lime. Soluble salts can easily be dissolved to provide electrolyte solutions. This is a simple way to control the concentration and ionic strength. The concentration of solutes affects many colligative properties, including increasing the osmotic pressure, and causing freezing-point depression and boiling-point elevation. Because the solutes are charged ions they also increase the electrical conductivity of the solution. The increased ionic strength reduces the thickness of the electrical double layer around colloidal particles, and therefore the stability of emulsions and suspensions. The chemical identity of the ions added is also important in many uses. For example, fluoride containing compounds are dissolved to supply fluoride ions for water fluoridation. Solid salts have long been used as paint pigments, and are resistant to organic solvents, but are sensitive to acidity or basicity. Since 1801 pyrotechnicians have described and widely used metal-containing salts as sources of colour in fireworks.
