Everything below concerns vaccine adjuvant. We keep the language plain, cite what the science says, and separate well-supported claims from open questions.
Last reviewed on 2025-08-09. Where a claim depends on a specific study, the study is described rather than over-claimed.
Identity and purity testing for thymosin alpha 1 relies mainly on reversed-phase high-performance liquid chromatography and mass spectrometry. Chromatography separates the parent peptide from truncated or modified variants, while mass spectrometry confirms the expected molecular mass. Amino acid analysis and peptide mapping provide additional sequence confirmation. Counterion content, water content, and residual solvents are measured separately as part of specification testing. No single method captures every attribute, so laboratories combine several techniques.
The peptide lacks cysteine, methionine, and tryptophan, so disulfide scrambling and sulfur oxidation are not major degradation routes. Instead, aspartate residues can undergo isomerization or cyclization to succinimide intermediates, generating isoaspartate variants. Hydrolysis of peptide bonds also occurs slowly in solution. These changes may reduce biological activity even when the main peak remains detectable. Stability studies therefore track both potency and the appearance of related substances.
Thymosin alpha 1 was identified in 1977 as a component of thymosin fraction 5, a heterogeneous preparation used in early studies of thymic function. Investigators purified the active material and determined its amino acid sequence, which enabled chemical synthesis. Work in the following decades concentrated on T-cell maturation and immune reconstitution in animals and small human cohorts. Early preparations varied in composition, so results from that period are difficult to compare with studies using defined synthetic peptide.
Clinical research has examined the peptide in chronic hepatitis B and C, as a vaccine adjuvant, and in sepsis and oncology settings. Findings across trials are mixed; some report changes in selected immune markers, while others find no clear clinical benefit. Many studies are small and define outcomes differently, which limits comparison. Regulatory approval is confined to a few countries, and the compound is not an approved drug in the United States or most of Europe.

=== Medical use === The appeal of conotoxins for creating pharmaceutical drugs is the precision and speed with which the chemicals act; many of the compounds target only a particular class of receptor. This means that they can reliably and quickly produce a particular effect on the body's systems without side effects; for example, almost instantly reducing heart rate or turning off the signaling of a single class of nerve, such as pain receptors. Ziconotide, a powerful atypical painkiller, was initially isolated from the venom of the magician cone snail, Conus magus. It was approved by the U.S. Food and Drug Administration in December 2004 under the name Prialt. Other drugs based on cone snail venom targeting Alzheimer's disease, Parkinson's disease, depression, and epilepsy are in clinical or preclinical trials. Many peptides produced by the cone snails show prospects for being potent pharmaceuticals, such as AVC1, isolated from the Australian species, the Queen Victoria cone, Conus victoriae, and have been highly effective in treating postsurgical and neuropathic pain, even accelerating recovery from nerve injury. Geography and tulip cone snails, as well as the Conus kinoshitai, are known to secrete a type of insulin that paralyzes nearby fish by causing hypoglycaemic shock. They are the only two non-human animal species known to use insulin as a weapon. Cone snail insulin is capable of binding to human insulin receptors and researchers are studying its use as a potent fast-acting therapeutic insulin.
=== Phase III === Study 2000162 (Randomized, double-blind, placebo-controlled). Intended to evaluate Palifermin efficacy in reducing oral mucositis in subjects with hematologic malignancy undergoing chemotherapy with autologous peripheral blood progenitor cell transplantation. Patients were administered with 3 daily, consecutive IV doses (or placebo) of Palifermin (60 micrograms/kg) before chemotherapy and Filgrastim (60 micrograms/kg) was administered after transplantation for three days consecutively. Efficacy was demonstrated in the drug versus the placebo.
Before sequences can be analyzed, they are obtained from a data storage bank, such as GenBank. DNA sequencing is still a non-trivial problem as the raw data may be noisy or affected by weak signals. Algorithms have been developed for base calling for the various experimental approaches to DNA sequencing.

Romania is the largest country in Southeastern Europe and the twelfth-largest in Europe, having an area of 238,397 square kilometres (92,046 sq mi). It lies between latitudes 43° and 49° N and longitudes 20° and 30° E. The terrain is distributed roughly equally between mountains, hills, and plains. The Carpathian Mountains dominate the centre of Romania, with 14 mountain ranges reaching above 2,000 m or 6,600 ft—the highest is Moldoveanu Peak at 2,544 m or 8,346 ft. They are surrounded by the Moldavian and Transylvanian plateaus, the Pannonian Plain and the Wallachian plains. Romania is home to six terrestrial ecoregions: Balkan mixed forests, Central European mixed forests, East European forest steppe, Pannonian mixed forests, Carpathian montane conifer forests, and Pontic steppe. Natural and semi-natural ecosystems cover about 47% of the country's land area. There are almost 10,000 km2 (3,900 sq mi) (about 5% of the total area) of protected areas in Romania covering 13 national parks and three biosphere reserves. The Danube river forms a large part of the border with Serbia and Bulgaria, and flows into the Black Sea, forming the Danube Delta, which is the second-largest and best-preserved delta in Europe, and a biosphere reserve and a biodiversity World Heritage Site. At 5,800 km2 (2,200 sq mi), the Danube Delta is the largest continuous marshland in Europe, and supports 1,688 different plant species alone. Romania has one of the largest areas of undisturbed forest in Europe, covering almost 27% of its territory.
Most higher education institutions in Germany are public and operated by the states. All professors are public servants. Public universities are generally held in higher esteem than their private counterparts. From 1972 through 1998, public universities were tuition-free; however, some states have since adopted low tuition fees.
Type I: Atresia is restricted to the common bile duct. Type II: Atresia of the common hepatic duct. Type III: Atresia involves the most proximal part of the bile ducts (>95% of all cases). In approximately 10% of cases, other anomalies may be associated with biliary atresia. The most common of these syndromic forms is BASM and might include heart lesions, polysplenia, situs inversus, absent venae cavae, and a preduodenal portal vein. Progressive cirrhosis is associated with signs and symptoms of portal hypertension, such as esophagogastric varix bleeding, hypersplenism, hepatorenal syndrome, and hepatopulmonary syndrome. In an Egyptian study, abnormally high levels of aflatoxin B1 and to a lesser extent aflatoxin B2 was found in liver tissue and blood of all neonates with biliary atresia. Aflatoxins may cause extensive damage to the hepatocytes leading to hepatitis and damage to bile ducts causing inflammation, adhesions and final obstruction of bile ducts. The affected neonates have a genetic detoxification defect that does not allow them to detoxify these aflatoxins timely or effectively. The babies have homozygous deficiency of glutathione S transferase (GST) M1. The aflatoxin damaged liver cells and bile duct cells are removed by neutrophil elastase and by involvement of immune system mediators such as CCL-2 or MCP-1, tumor necrosis factor (TNF), interleukin-6 (IL-6), TGF-beta, endothelin (ET), and nitric oxide (NO). Among these, TGF-beta is the most important pro-fibrogenic cytokine that can be seen in progressive cirrhosis.
=== Tumours === Proteases are associated with cancer progression due to their ability to degrade extracellular matrices, which facilitates invasion and metastasis; these enzymes target a diversity of substrates and favour all steps of tumour production; some proteases have tumour-suppressive effects, associated with more than 30 different enzymes that belong to three distinct protease classes.

=== Catholic === American Order of United Catholics - Founded in January 1896 in New York City by Catholics who wished to counter the influence of the American Protective Association. It was "expected of the founders" that they would demand candidates for office who disapproved of the APA or other organizations that sought to discriminate against Catholics. A Supreme Council was organized on March 7, 1896, and the Order was organized "upon the usual secret society lines". They issued a circular that proclaimed that the Church did not oppose secret societies, except those that were oathbound. Catholic Aid Association - Founded in 1878 by German Catholics in Minnesota. The order began with 464 members from 10 parishes and was called the Deutsche Römisch-Katholische Unterstützungs-Gesellschaft von Minnesota; adopted its present name in 1923. Had 58,722 members in 1965, and approximately 78,000 in 1979. Headquarters in St. Paul, Minnesota. Local groups are called "subordinate Councils", of which there were 240 in 1979. Annual convention called the "Grand Council". Has rituals for initiation, installation of officers, and other purposes. Open to Roman Catholics 16-65 who are not a member of a secret society condemned by the Church. Sponsors matching grants program for Catholic elementary schools and religious education programs. Also, a College Tuition Scholarship Program has helped 800 CAA members receive degrees. Also sponsors banquets, family outings, dances, and youth activities; now Catholic United Financial.
In 2025, Alveus rescued a former pet emu, Nolie. She was named by Mr.Beast after helping in her rescue and helping the sanctuary through donations. Another popular Emu on social media is Emmanuel, a resident of Knuckle Bump Farms in south Florida. Taylor Blake, the farm's owner, since 2013 has recorded video shorts explaining aspects of the farm and is often interrupted as Emmanuel the Emu photobombs her videos, earning constant rebukes; the term "Emmanuel don't do it!" has become popular on social media.
Menthyl nicotinate is an organic compound with the formula C16H23NO2. It is the ester of nicotinic acid (niacin, vitamin B3) and menthol. At room temperature, menthyl nicotinate is a colorless, odorless, viscous liquid. Being a topical lipophilic niacin derivative, menthyl nicotinate is used in cosmetics and personal care products, personal lubricants and intimate hygiene compositions. Menthyl nicotinate is rapidly absorbed through the stratum corneum and slowly hydrolyzed by skin esterase into niacin and menthol. Such time-dependent release of niacin and menthol, in an equimolar ratio, prevents the excessive niacin-flush effect that is usually observed with other nicotinates. Niacin is a precursor to coenzyme nicotinamide adenine dinucleotide (NAD), which is essential to all cellular processes involved in immune response and DNA-repairing of photodamaged skin cells. Niacin has also been used and tested for the purpose of enhancing detoxification by removing skin lipid-stored xenobiotics. In vitro testing has evidenced menthyl nicotinate's fast skin absorption kinetics and slow percutaneous delivery of niacin. Its antioxidant, antipollution, and protective efficacy against different kinds of damaging agents (UV radiation, oxidizing agents, urban particulates, and cigarette smoke) has also been evaluated. Results indicate that menthyl nicotinate significantly enhances skin barrier function.
=== Political changes === The revolution brought Romania vast attention from the outside world. Initially, much of the world's sympathy went to the FSN government under Ion Iliescu, a former member of the CPR leadership and a Ceaușescu ally prior to falling into the dictator's disfavour in the early 1980s. The FSN, composed mainly of former members of the second echelon of the CPR, immediately assumed control over the state institutions, including the main media outlets such as the national radio and television networks. They used their control of the media to launch attacks against their political opponents, newly created political parties that claimed to be successors to those existing before 1948. Around the same time, all Romanian numbers stations ceased transmitting, including a number station called "Ciocârlia/The Skylark", also known as "V01" after the revolution. Much of that sympathy was squandered during the Mineriads. Massive protests erupted in downtown Bucharest as political rallies organised by the opposition parties during the presidential elections, with a small part of the protesters deciding to stand ground even after Iliescu was re-elected with an overwhelming majority of 85%. Attempts by police to evacuate the remaining protesters resulted in attacks on state institutions, prompting Iliescu to appeal to the country's workers for help. Infiltrated and instigated by former Securitate agents, in the following days a large mass of workers, mainly miners, entered Bucharest and attacked and fought with anti-government protesters and gathered bystanders.
In October 2016, word leaked through social media that Arby's was about to test a venison sandwich, which Arby's confirmed, selecting 17 stores in Georgia, Michigan, Minnesota, Pennsylvania, Tennessee, and Wisconsin (all major deer hunting states) to offer it during a four-day test during those states' respective hunting seasons. Prior to the start of the promotion, USA Today published the locations of all 17 participating restaurants. Both due to curiosity and heavy demand from hunters, the sandwiches sold out in all markets on the first day of the test. Another USA Today article reported that the farm-raised venison was imported from New Zealand. In the following year, Arby's announced that the venison sandwich would return nationwide on October 21, 2017, also available in limited quantities. In September 2017, Arby's introduced the Chicken Pepperoni Parm sandwich, their version of a chicken parmigiana sandwich which also contains pepperoni slices. In October 2017, Arby's announced that three locations in Colorado, Montana, and Wyoming will offer an elk sandwich for a limited time. The farm-raised elk meat that was used to make the sandwiches was obtained from the same farm in New Zealand that provides the venison to Arby's since many states, such as Montana, prohibit the raising of game animals on commercial farms. The following October, Arby's once again offered a featured wild game sandwich in 16 of its restaurants. This time, it would be a duck breast sandwich topped with a cherry sauce and crispy onions.

The lyophilized powder is kept refrigerated at 2 to 8 degrees Celsius and protected from light. Reconstituted solutions should be used promptly. Freezing and thawing repeatedly is avoided.
Reversed-phase HPLC is the primary tool for purity, paired with mass spectrometry for identity. Amino acid analysis and peptide mapping add sequence confirmation. Several techniques are combined because no single test covers every attribute.
It lacks sulfur-containing residues, so oxidation is limited. Aspartate isomerization and slow hydrolysis are the main concerns. Solution stability is shorter than that of the lyophilized powder.
Trials differ in patient population, dose schedule, background treatment, and the endpoints used to judge success. Many are small and single-center, so random variation can dominate the reported effects.
