Everything below concerns tissue repair. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2026-04-11. Where a claim depends on a specific study, the study is described rather than over-claimed.
Physical descriptions in supplier documents and papers usually list the compound as a white to off-white powder. It dissolves readily in water and in common aqueous buffers, and solutions are often prepared fresh before an experiment. Molecular mass near 1419 daltons helps verify identity during mass spectrometry. The powder is somewhat hygroscopic, so moisture exposure can alter the measured mass of a sample. Purity is typically reported as a percentage from chromatographic analysis.
BPC-157 is a synthetic fifteen-amino-acid peptide whose sequence is GEPPPGKPADDAGLV. Its name derives from the phrase body protection compound, a term applied to a protein fraction originally detected in human gastric juice. The short peptide is not that full protein; it corresponds to a stable fragment of the larger molecule. Researchers frequently describe it as a pentadecapeptide because it contains exactly fifteen residues. Its neutral molecular mass is approximately 1419 daltons.
Doses in the literature are usually expressed in micrograms or nanograms per kilogram of body weight. Investigators have administered the peptide by several routes, including injection and oral delivery, depending on the question asked. Route and dose vary widely across studies, which complicates direct comparison of results. Many papers report effects at low doses, but the absence of a standardized protocol limits generalization. Reporting practice differs between research groups.
Some properties, such as the peptide's sequence and molecular mass, are firmly established. Other claims, particularly about mechanism and clinical benefit, remain open questions. Proposed mechanisms include effects on nitric oxide signaling and on cell migration, but these are hypotheses supported by limited evidence. Reviewers often note that the field lacks large controlled human trials. Positive animal findings are best treated as signals for further study rather than as settled conclusions.

Common synonyms in catalogs include pentadecapeptide BPC 157, BPC157, and the full sequence name. A CAS registry number in the 137525-51-0 range is frequently listed, though the assignment should be verified against the supplier certificate of analysis. The name itself is not a pharmacopoeial designation, and there is no standardized international nonproprietary name. Distinguishing genuine material from related fragments generally requires mass spectrometry, since several truncated sequences share similar chromatographic behavior.
BPC-157 is a synthetic pentadecapeptide whose sequence is commonly given as Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val. It is described in the literature as a fragment of a larger protein found in human gastric juice, referred to as body protection compound. The peptide was first characterized in the early 1990s by a research group in Zagreb, Croatia. Its molecular formula is C62H98N16O22 and its monoisotopic mass is approximately 1419 daltons.
Proposed mechanisms include interaction with the nitric oxide system, modulation of growth factor signaling, and effects on blood vessel formation. None of these has been established as the primary mode of action, and some proposed pathways rest on indirect measurements. Whether the reported effects depend on a specific receptor has not been determined. Stability in gastric acid, unusual for a peptide of this size, is also reported in animal work, but the reason for it is not firmly established.
Published studies on BPC-157 are dominated by animal models. Commonly used endpoints include healing of surgically induced lesions in the stomach, tendon-to-bone attachment after transection, and recovery from experimentally induced vascular or intestinal damage. Many of these reports come from a small number of research groups, and the peptide is often described as acting across a wide range of tissue types. That breadth is itself a point of discussion, since one molecule influencing many unrelated systems is unusual.
Published storage guidance follows general peptide practice rather than product-specific studies. The dry powder is typically kept at minus 20 degrees Celsius, away from light and moisture. Once reconstituted, solutions are generally refrigerated and used over days to weeks, because the aqueous environment slowly promotes hydrolysis and oxidation. Long-term data on degradation rates or breakdown products are sparse. Stated shelf lives from different producers vary widely, reflecting the absence of a shared reference standard.
BPC-157 is a synthetic peptide built from fifteen amino acid residues. Its sequence comes from a larger protein fragment that researchers isolated from human gastric juice and described as a body protection compound. The fragment contains glycine, glutamic acid, five prolines, lysine, alanine, two aspartic acids, leucine, and valine. The number 157 in the name refers to the position of the stretch within the parent protein. Material used in laboratories is manufactured rather than extracted from stomach fluid.
The molecule carries 15 residues, a molar mass near 1419.5 g/mol, and the formula C62H98N16O22. Its structure features a proline-rich central region, a pair of adjacent aspartic acid residues, and no cysteine. The absence of cysteine means no disulfide bonds can form, which simplifies refolding and reconstitution. Suppliers usually ship the material as a freeze-dried powder that appears white to off-white. It dissolves readily in water and in saline solutions.
Proposed mechanisms in the literature involve the nitric oxide system, vascular endothelial growth factor signaling, and epidermal growth factor receptor pathways. Some studies report changes in blood vessel formation or in inflammatory mediators, while others describe interactions with nervous tissue. Much of this evidence rests on molecular markers in cultured cells or animal models. Whether the same pathways operate the same way in humans has not been established. Authors therefore tend to describe mechanisms as hypothetical rather than settled.
Direct human evidence is scarce. One trial in ulcerative colitis delivered the compound by enema and produced limited publicly reported results without a clear benefit. The compound is not an approved medicine in most jurisdictions. In many markets it is sold as a research chemical; in others it falls under prescription or controlled categories. Regulators have not confirmed any claimed medical use, and product labels rarely undergo premarket review.
Most published reports describe experiments in rodents rather than in people. These studies examine outcomes in tendons, ligaments, bone, stomach lining, and intestinal tissue. In rat and mouse models, a frequently reported effect is faster healing or reduced damage. Sample sizes are usually small, and a substantial share of the work originates from a small number of research groups. Independent replication is limited, so how far the findings extend to humans remains an open question.
The most prominent natural toxin groups that exist in aquatic environments are mycotoxins, algal toxins, bacterial toxins, and plant toxins (8). These marine biotoxins are dangerous to human health and have been widely studied due to their high potential to bioaccumulate in edible parts of seafood. Autotrophic bacteria and algae are unrelated organisms; however, in aquatic environments, they are both primary producers. Cyanobacteria are an important autotrophic bacteria in the water food web. Explosions of cyanobacteria known as algal blooms can produce cyanotoxins harmful to both the ecosystem and human health. These harmful algal blooms are more likely to be produced at a dangerous amount when there is an excess of nutrients, the temperature is 20 °C, there is more light, and calmer waters. Eutrophication and other contamination can lead to an environment that promotes cyanobacteria blooms. Processes that promote an excess of nutrients, and human activities, such as agricultural runoff and sewage overflows, are primarily responsible. Other factors include algal species and grazers being in higher concentrations, allowing for an abundance of cyanobacterial organisms that are associated with the production of toxins. Detection of the extent of an algal bloom begins by taking samples of water at various depths and locations in the bloom.
25. Indian J Exp Biol. 2010 Apr;48(4):378-82. Neuroprotective effect of hydroalcoholic extract of dried fruits of Trapa bispinosa Roxb on lipofuscinogenesis and fluorescence product in brain of D-galactose induced ageing accelerated mice. Ambikar DB(1), Harle UN, Khandare RA, Bore VV, Vyawahare NS. Author information: (1)Department of Pharmacology, AISSMS College of Pharmacy, Kennedy Road, Pune 411 001, India. Effect of hydroalcoholic extract T. bispinosa (TB) was studied on fluorescence product and biochemical parameter like lipid peroxidation, catalase activity and glutathione peroxidase activity in the brain of female albino mice. Ageing was accelerated by the treatment of 0.5 ml 5% D-galactose for 15 days. This resulted in increased fluorescence product, increase lipid peroxidation and decrease antioxidant enzyme like glutathione peroxides and catalase in cerebral cortex. After cotreatment with hydroalcoholic extract of TB (500 mg/kg, po) there was decrease in fluorescence product in cerebral cortex. Moreover, TB inhibited increase lipid peroxidation and restores glutathione peroxidase and catalase activity in cerebral cortex as compare to ageing accelerated control group. To conclude TB found to be effective antioxidative agent which could to some extent reverse D-galactose induced ageing changes resulted due to oxidative damage.
As a result, more affordable headsets designed to accommodate mobile devices were also released, using the devices to create the stereoscopic display, some of the positioning functions, and other VR tracking embedded in the additional hardware. On June 25, 2014, Google officially introduced Google Cardboard, an inexpensive headset package that constructed from cardboard for use with Android phones; the completed headset creates the necessary visual space to support stereoscopic view from the phone's display. Samsung, in conjunction with Oculus, released the Samsung Gear VR in 2015 to support its Samsung Galaxy smartphones; services for the Gear VR ended in 2020. Nintendo released the Nintendo Labo VR Kit in 2019 as part of its Labo series of toys-to-life cardboard products. A handful of Nintendo Switch games support Labo VR functionality, such as the 2017 games Super Mario Odyssey and The Legend of Zelda: Breath of the Wild. Despite the availability of low-cost hardware for VR, the technology had still not taken off for video games by 2018 as had been expected when the Oculus Rift was announced. This was attributed to the lack of a killer application, a game that would drive people to buy the hardware to play it. There had been several games from smaller studios that had been considered successful, such as Superhot VR and Beat Saber, but the triple-A studios had not ventured into the area. Sales of VR hardware had been steadily increasing since 2016, but were still under 10 million units by 2018, and there were signs manufacturers were starting to back off in this area.
=== Epilepsy === From the results seen in humans with drugs such as Epidiolex and Sativex in scientific studies and reviews, it could be expected that CBD-based products would be helpful to manage seizures in dogs. However, despite the numerous case reports presented by veterinary neurologists supporting the benefits of CBD as adjunctive therapy, as of December 2020, published controlled studies have not shown a statistically significant decrease in the number of seizures across the groups receiving CBD.

While artesunate is used primarily as treatment for malaria, there is some evidence that it may also have some beneficial effects in Schistosoma haematobium infection, but has not been evaluated in large randomized trials. Artesunate is used as the treatment of choice for severe malaria by the World Health Organization (WHO) over quinine.
=== Glioblastoma === Abnormal cell growth and formation of mass in the brain tissue or nearby regions may cause brain cancer. Constant headaches, seizures, and blurred vision are common symptoms. Glioblastoma (GBM) is the most fast-growing and deadliest brain tumor. Though the main cause of glioblastoma remains unknown, it originates when astrocytes mutate and multiply uncontrollably forming tumors in the frontal and temporal lobes of the brain. The challenge with current therapeutics is to initiate tumor cell apoptosis with no toxic effects to healthy brain tissue. Nanoparticles loaded with chemotherapeutics delivered through the intranasal route show promising results in treating glioblastoma. PLGA-based nanoparticles loaded with paclitaxel or doxorubicin conjugated with a RGD sequence targeted the glioblastoma microenvironment and reduced tumor volume through cell death. MicroRNA-21 (miR-21) inhibits pro-apoptotic genes increasing progression of glioblastoma. Self-assembling nanoparticles produced with anti-tumor peptides were administered intranasally and reduced miR-21 levels increasing tumor cell apoptosis.

Mithridate, also known as mithridatium, mithridatum, mithridaticum, Confectio Damocratis, or Damocrates's Confection is a semi-mythical remedy with as many as 65 ingredients, used as an antidote for poisoning, and said to have been created by Mithridates VI Eupator of Pontus in the 1st century BC. It was one of the most complex and highly sought-after drugs during the Middle Ages and the Renaissance, particularly in Italy and France, where it was in continual use for centuries. An updated recipe called theriac (Theriacum Andromachi) was known well into the 19th century. Mithridate takes its name from its inventor, Mithridates VI, king of the ancient Anatolian Kingdom of Pontus (134 to 63 BC), who is said to have so fortified his body against poisons with antidotes and preservatives that when he tried to kill himself, he could not find any poison that would have an effect, and, according to some legends, had to ask a soldier to run him through with a sword. The recipe for the reputed antidote was found in his cabinet, written with his own hand, and was carried to Rome by Pompey. It was translated into Latin by Pompey's freedman Lenaeus, and later improved upon by Nero's physician Andromachus and Marcus Aurelius' physician Galen. It likely underwent considerable alterations since the time of Mithridates. After realizing the anti-toxic effects of snake meat, Andromachus made Faroug antidote with changes in the previous formulas. In the Middle Ages, mithridate was also used as part of a regimen to ward off potential threats of plague.
Apigenin (4′,5,7-trihydroxyflavone), found in many plants, is a flavone compound that is the aglycone of several naturally occurring glycosides. It is a yellow crystalline solid that has been used to dye wool. Apigenin is abundant in parsley, celery, celeriac, and chamomile flowers. It occurs in many fruits and vegetables, with the highest concentrations in dried and fresh parsley.

A 2017 film adaptation of Wonder, starring Julia Roberts, Owen Wilson and Jacob Tremblay, was released in November 2017. A stage adaption premiered in 2025, with actor Garrett McNally, who has Treacher Collins syndrome himself, portraying the character in certain shows. Alison Midstokke, who appears in the drama film Happy Face (2018), is an actress and activist who has the condition.
===== Pore size ===== In a microporous material where physisorption and weak van der Waals forces dominate adsorption, the storage density is greatly dependent on the size of the pores. Calculations of idealized homogeneous materials, such as graphitic carbons and carbon nanotubes, predict that a microporous material with 7 Å-wide pores will exhibit maximum hydrogen uptake at room temperature. At this width, exactly two layers of hydrogen molecules adsorb on opposing surfaces with no space left in between. 10 Å-wide pores are also of ideal size because at this width, exactly three layers of hydrogen can exist with no space in between. (A hydrogen molecule has a bond length of 0.74 Å with a van der Waals radius of 1.17 Å for each atom; therefore, its effective van der Waals length is 3.08 Å.)
In 1998, at the 5th Conference of the Inter‑American Masonic Confederation (CMI) (Spanish: Confederación Masónica Interamericana), the 95 member bodies of CMI recognized the Grand Lodge of Cuba as "regular and correct," and rejected the regularity claims of the Grand Lodge of Cuba in Exile. In 2000, the Cuban government pressured the Grand Lodge of Cuba to elect a man named José Manuel Collera Venta as Grand Master. In 2005, when the Grand Lodge of Cuba attempted to expel Venta from Freemasonry "for an undisclosed reason," the Cuban government again intervened and stopped that from happening. By May 8, 2000, two factions existed within Cuban Freemasonry. One faction based in the National Temple headquarters preferred not to display any dissent against the government for the fear that their Lodges would be shuttered, but another faction within the leadership of the local Lodges advocated that Freemasons should be faithful to their statues, maintaining an impartial political position, no matter the consequences that might befall them. Lodges further away from Havana had more freedom due to less infiltration by government agents. In 2002, the Grand Lodge of Cuba reestablished its relationship with the Grand Lodge of Italy and the Grand Orient of Italy. By the year 2008, there were 29,110 Freemasons in Cuba, compared to 1980, when there were only 19,690.
In the US, medical residencies traditionally require lengthy hours of their trainees. Early residents literally resided at the hospitals, often working in unpaid positions during their education. During this time, a resident might always be "on call" or share that duty with just one other physician. The American public, and the medical education establishment, recognized that such long hours were counter-productive, since sleep deprivation increases rates of medical errors. This was noted in a landmark study on the effects of sleep deprivation and error rate in an intensive-care unit. The Accreditation Council for Graduate Medical Education (ACGME) has limited the number of work-hours to 80 hours weekly (averaged over 4 weeks), overnight call frequency to no more than one overnight every third day, and 10 hours off between shifts. Still, a review committee may grant exceptions for up to 10%, or a maximum of 88 hours, to individual programs. Until early 2017, duty periods for postgraduate year 1 could not exceed 16 hours per day, while postgraduate year 2 residents and those in subsequent years can have up to a maximum of 24 hours of continuous duty. After early 2017, all years of residents may work up to 24-hour shifts. While these limits are voluntary, adherence has been mandated for the purposes of accreditation, though lack of adherence to hour restrictions is not uncommon.

The letters BPC stand for body protection compound. The number 157 refers to a specific fragment designation from early work on gastric proteins. The full name is a label for a synthetic fifteen-amino-acid peptide rather than a naturally isolated drug.
No. The gastric protein is larger, while BPC-157 is a short fragment sequence. The peptide is produced synthetically for research use. The relationship is one of sequence origin, not chemical identity.
It is most often supplied as a lyophilized powder, frequently as the acetate salt. The powder is reconstituted with water or a buffer before use. Free-base and other salt forms also exist but are less common in catalogs.
Human data are limited. Most evidence comes from animal experiments and from small or uncontrolled reports. The absence of large trials means clinical effects and safety are not firmly established.
