This is a working overview of thymus extract, written for readers who want more than a one-paragraph summary but less than a textbook.
This page was last updated on 2026-08-01 and is reviewed periodically as new material appears.
Overall evidence quality varies considerably. A large share of published reports come from single centers, rely on surrogate immunological markers, or lack adequate control groups. Systematic reviews have highlighted this heterogeneity as a barrier to pooling results. Open questions include which patients, if any, might benefit, what treatment duration is appropriate, and whether any effect is independent of standard care. The peptide is often described as an immune modulator rather than a therapy for one disease, which complicates confirmatory trial design.
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.
Long-term storage is generally at minus twenty degrees Celsius or colder, preferably desiccated and protected from light. Lyophilized material is more stable than reconstituted solution, which degrades faster at room temperature. Stability depends on pH, ionic strength, and the presence of oxidising agents. Published stability data for the peptide are limited, so storage claims in catalogues should be treated as general guidance rather than measured guarantees. Freeze-thaw cycles are kept to a minimum.
Identity and purity are normally confirmed by reversed-phase high-performance liquid chromatography and mass spectrometry. The expected mass for the acetylated 28-residue peptide is close to 3108 daltons, and a mass shift indicates a modification or truncation. Peptide mapping after enzymatic digestion can resolve sequence-level questions. Counter-ion content, water content, and residual solvents are separate quality attributes that a certificate of analysis may or may not report. Aggregation is monitored by size-exclusion chromatography when relevant.

Clinical interest has centered on chronic viral hepatitis, on immune restoration in various conditions, and on use as an adjuvant intended to improve responses to vaccines. Trials have reported mixed results, and regulatory status differs sharply between countries; in some places it is a prescription product, while elsewhere it is sold without an approved therapeutic indication. Because published studies vary widely in design, population, and endpoints, comparisons across them are difficult and no single conclusion covers the whole literature.
Thymosin alpha 1 is a short peptide of 28 amino acid residues that derives from the amino terminal region of a larger precursor protein known as prothymosin alpha. The peptide carries an acetyl group on its first residue and contains no disulfide bonds or carbohydrate chains. Its sequence is highly conserved across mammalian species, which is one reason laboratories treat it as a molecule with a defined and reproducible structure rather than a variable tissue extract. The name follows an early naming convention for thymus-derived fractions and does not imply that the peptide acts as a hormone in the classical endocrine sense.
Identity and purity are assessed with a small set of standard peptide methods. Reversed-phase high-performance liquid chromatography separates the main peak from truncated or oxidized species, and its area percentage is the usual purity measure. Mass spectrometry confirms the observed molecular mass against the expected value, while amino acid analysis or peptide mapping checks composition and sequence. Specifications for research-grade material are often stated as 95 percent or higher, though the exact limit depends on the supplier and the intended use.
Laboratory supplies of the peptide usually arrive as a lyophilized powder in sealed vials. The powder is hygroscopic, so a vial should be allowed to reach room temperature before it is opened to prevent condensation on the contents. Weighing and transfer are best performed in a low-humidity environment with clean tools. Once dissolved, the solution should be mixed gently rather than vortexed, because foaming and shear can reduce recovery of the peptide.
The peptide was described in the 1970s as a component of thymic extracts, and early research focused on restoring immune function in immunodeficiency states. A synthetic version entered clinical development in the 1980s and is approved as a drug in several countries for conditions such as chronic hepatitis B and certain immunodeficiencies. Approval status varies widely by jurisdiction, and in the United States it is not an approved therapeutic. Regulatory and clinical positions differ, so statements about efficacy should be tied to specific indications and studies.
Thymosin alpha-1 is a synthetic peptide of 28 amino acids, corresponding to the N-terminal fragment of prothymosin alpha. Its sequence begins with acetylation at the N-terminus, a modification that affects stability and receptor interaction. The peptide is acidic, with a calculated isoelectric point near 4.2, and carries no disulfide bonds, so its secondary structure is largely flexible in solution. Molecular mass is approximately 3108 daltons. The native form was first isolated from bovine thymus tissue, while pharmaceutical material is produced by solid-phase peptide synthesis.
Within the immune system, the peptide acts on several cell types rather than a single target. Reported activities include promotion of T-cell maturation, enhancement of natural killer cell activity, and modulation of cytokine production by dendritic cells and macrophages. Some of these effects appear to operate through toll-like receptor signaling, though the precise receptor-level mechanism remains debated. Whether the observed immune changes translate into clinical benefit is a separate question and depends on the indication studied.
Identity and purity are usually checked by reverse-phase high-performance liquid chromatography, which separates the intact chain from truncated products, together with mass spectrometry for confirmation of the expected mass. Peptide mapping after enzymatic digestion and amino acid analysis add sequence-level evidence. Release testing also covers water content, residual solvents, and counter-ions, all of which influence measured mass and stability. Related-peptide limits are commonly expressed as a percentage of total peak area, with individual unspecified impurities held below a lower threshold.
The lyophilized peptide is a white to off-white powder that dissolves freely in water and in aqueous buffers near neutral pH. Because the molecule carries a net negative charge under physiological conditions, saline and phosphate solutions are the usual vehicles, while strongly acidic media are avoided. Stock solutions are commonly divided into small aliquots so that repeated freezing and thawing can be limited, since cycling may encourage aggregation. Solubility in organic solvents is poor and those solvents are seldom used as primary diluents.
Recommended storage for the dry powder is a freezer near minus twenty degrees Celsius, kept desiccated and away from light. Once dissolved, the peptide is less stable and is usually held at two to eight degrees Celsius for short intervals or frozen for longer storage. Stability studies focus on the acetylated terminus and the disulfide linkage because those features define the intact molecule. Common degradation routes include cysteine oxidation, deamidation of asparagine or glutamine side chains, and slow formation of higher-molecular-weight species.
=== Business career: expansion and near disaster === By now the property boom was in full swing. Heseltine and Labovitch established first one, then a group of companies under the name "Bastion Properties". Heseltine later recorded that he and Labovitch bought at least three properties in W1 and W2 which they were able to sell at a profit before they had completed the original purchases. They also built eight small houses in Queensborough Mews, Bayswater. They bought a 58-year lease on a block of seven properties at Stafford Terrace, off Kensington High Street, which they converted into flats and built houses for Stepney Borough Council. Bastion also planned to build an estate of up to 126 houses at Tenterden, Kent, which failed to sell. In order to attract other buyers to the empty estate Heseltine had to accept an offer of £4,000 for the first house, which had been valued at £7,250. The estate was beset with repair problems until after Heseltine's election to Parliament. Heseltine and Labovitch also founded the magazine publishing company Cornmarket, and brought out Directory of Opportunities for School Leavers and Directory of Opportunities for Qualified Men, which earned a steady income from advertising. Canadian, French and German versions were also launched, although these were less profitable. In late 1959, using £10,000 of a £30,000 profit on selling a freehold site off Regents Park, they acquired the famous (but unprofitable) magazine Man About Town whose title was shortened to About Town then simply Town.
The tau proteins (abbreviated from tubulin associated unit) form a group of six highly soluble protein isoforms produced by alternative splicing from the gene MAPT (microtubule-associated protein tau). They have roles primarily in maintaining the stability of microtubules in axons and are abundant in the neurons of the central nervous system (CNS), where the cerebral cortex has the highest abundance. They are less common elsewhere but are also expressed at very low levels in CNS astrocytes and oligodendrocytes. Degeneration of the nervous system in forms of dementia such as Alzheimer's disease, frontotemporal dementia (FTD) disorders, and Parkinson's disease are associated with tau protein pathology, in which tau abnormally aggregates. The tau proteins were identified in 1975 as heat-stable proteins essential for microtubule assembly, and have since been characterized as intrinsically disordered proteins.
Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. It is an isomer of another solvent, butanone.

=== Animal synthesis === There is some information on serum vitamin C concentrations maintained in animal species that are able to synthesize vitamin C. One study of several breeds of dogs reported an average of 35.9 μmol/L. A report on goats, sheep and cattle reported ranges of 100–110, 265–270 and 160–350 μmol/L, respectively. The biosynthesis of ascorbic acid in vertebrates starts with the formation of UDP-glucuronic acid. UDP-glucuronic acid is formed when UDP-glucose undergoes two oxidations catalyzed by the enzyme UDP-glucose 6-dehydrogenase. UDP-glucose 6-dehydrogenase uses the co-factor NAD+ as the electron acceptor. The transferase UDP-glucuronate pyrophosphorylase removes a UMP and glucuronokinase, with the cofactor ADP, removes the final phosphate leading to d-glucuronic acid. The aldehyde group of this compound is reduced to a primary alcohol using the enzyme glucuronate reductase and the cofactor NADPH, yielding l-gulonic acid. This is followed by lactone formation—utilizing the hydrolase gluconolactonase—between the carbonyl on C1 and hydroxyl group on C4. l-Gulonolactone then reacts with oxygen, catalyzed by the enzyme L-gulonolactone oxidase (which is nonfunctional in humans and other Haplorrhini primates; see Unitary pseudogenes) and the cofactor FAD+. This reaction produces 2-oxogulonolactone (2-keto-gulonolactone), which spontaneously undergoes enolization to form ascorbic acid. Reptiles and older orders of birds make ascorbic acid in their kidneys. Recent orders of birds and most mammals make ascorbic acid in their liver.
=== Legal status === In the United States, benzodiazepines are Schedule IV drugs under the Federal Controlled Substances Act, even when not on the market (for example, flunitrazepam), with the exception of flualprazolam, etizolam, clonazolam, flubromazolam, and diclazepam which are placed in Schedule I. In Canada, possession of benzodiazepines is legal for personal use. All benzodiazepines are categorized as Schedule IV substances under the Controlled Drugs and Substances Act. In the United Kingdom, benzodiazepines are Class C controlled drugs, carrying the maximum penalty of 7 years imprisonment, an unlimited fine, or both for possession and a maximum penalty of 14 years imprisonment, an unlimited fine, or both for supplying benzodiazepines to others. In the Netherlands, since October 1993, benzodiazepines, including formulations containing less than 20 mg of temazepam, are all placed on List 2 of the Opium Law. A prescription is needed for possession of all benzodiazepines. Temazepam formulations containing 20 mg or greater of the drug are placed on List 1, thus requiring doctors to write prescriptions in the List 1 format. In East Asia and Southeast Asia, temazepam and nimetazepam are often heavily controlled and restricted. In certain countries, triazolam, flunitrazepam, flutoprazepam and midazolam are also restricted or controlled to certain degrees. In Hong Kong, all benzodiazepines are regulated under Schedule 1 of Hong Kong's Chapter 134 Dangerous Drugs Ordinance. Previously only brotizolam, flunitrazepam and triazolam were classed as dangerous drugs.
Due to his high popularity, Duterte remained influential before the national elections as several presidential candidates were open to his endorsement. As the Cusi faction was left without a standard bearer following Go's withdrawal, allies of Duterte endorsed different candidates. The Cusi faction eventually endorsed presidential candidate Marcos and some officials called for Duterte to do the same. Stressing he would remain neutral, Duterte refused to heed their calls and insisted on endorsing only Sara as vice president and 17 senatorial candidates. Additionally, in an effort to protect their integrity, Duterte barred his Cabinet members from campaigning for any candidate. Despite non-endorsement, Duterte hinted on the next president's preferred qualities: decisive, compassionate, a good judge of a person, and preferably, a lawyer; this led a PDP-Laban official to believe Duterte gave a "virtual endorsement" for Vice President Leni Robredo, who was Marcos' chief rival in the presidential race. In March 2022, Go said Duterte briefly met with Marcos and gave him advice on the presidency, but could not say whether Duterte gave Marcos an endorsement.
A language model may associate certain professions with specific genders if such patterns are prevalent in the data. Similarly, some image generation systems have been observed to generate images of men as CEOs more often than women. AI software, when using voice recognition software in particular, struggles to recognize and understand speech impediments. For example, people with a stutter struggle to activate voice-activated assistants such as Gemini and Siri due to how the software was trained. Companies that use AI systems to hire for new positions also filter out people with accents and speech due to voice recognition software incorrectly transcribing how candidates speak during the interview process. Because of this, people with disabilities and uncommon accents don't often make it to a human interviewer when these generative AI systems are used. This is due to many AI models being trained and produced in the United States, and therefore, off of American accents.
The large intestine contains multiple types of bacteria, and other microorganisms that can break down molecules the human body cannot process alone, demonstrating a symbiotic relationship. These microbes are responsible for gas production at host–pathogen interface, which is released as flatulence. Intestinal bacteria can also participate in biosynthesis reactions. For example, certain strains in the large intestine produce vitamin B12; an essential compound in humans for things like DNA synthesis and red blood cell production. However, the primary function of the large intestine is water absorption from digested material (regulated by the hypothalamus) and the reabsorption of sodium and nutrients. Beneficial intestinal bacteria compete with potentially harmful bacteria for space and nutrients, as the intestinal tract has limited resources. A ratio of 80–85% beneficial to 15–20% potentially harmful bacteria is proposed for maintaining homeostasis. An imbalanced ratio results in dysbiosis.

== Clinical research == Although lipoic acid has been tested in clinical research for potential use as a therapy for various diseases, the studies have been of limited quality, with no conclusive evidence that it is warranted as a therapeutic, as of 2026. According to the American Cancer Society as of 2013, "there is no reliable scientific evidence at this time that lipoic acid prevents the development or spread of cancer". As of 2015, intravenously administered ALA is unapproved anywhere in the world except Germany for diabetic neuropathy, but has been proven reasonably safe and effective. As of 2012, there was no good evidence alpha lipoic acid helps people with mitochondrial disorders. A 2018 review found that ALA had a small effect to reduce body weight, but is not cost-effective as a dietary supplement. A 2025 study indicated a positive effect in a cellular model of Friedreich's ataxia.
=== Grand Lodge of South Carolina === On March 27, 1818, the Grand Lodge of South Carolina chartered La Constancia Lodge, No. 50. On March 31, 1820, they chartered La Amenidad Lodge, No. 52. Both of these were chartered in Havana. In 1821, the Grand Lodge of Ancient Freemasons sent a communication to the Grand Lodge of South Carolina that a new Grand Lodge had been formed in Cuba, and La Amenidad Lodge, No. 52 had expressed its desire to transfer to the new Grand Lodge. The Grand Lodge of South Carolina accepted the arrangement. However, La Constancia Lodge, No. 50, remained a part of the Grand Lodge of South Carolina until its members surrendered its warrant around the year 1824, stating that their decision was made "in consequence of the religious and political persecutions to which they were subjected."
== Mythological origins == In Greek mythology, the centaur Chiron was a "Wounded Healer", after being poisoned with an incurable wound by one of Hercules's arrows. Jung mentioned the Chiron myth "wounding by one's own arrow means, first of all, the state of introversion"; For Jung, "a good half of every treatment that probes at all deeply consists in the doctor's examining himself... it is his own hurt that gives a measure of his power to heal. This, and nothing else, is the meaning of the Greek myth of the wounded physician." Jung felt that depth psychology can be potentially dangerous, because the analyst is vulnerable to being infected by his analysis by having his own wounds reopened. To avoid this, the analyst must have an ongoing relationship with the unconscious, otherwise he or she could identify with the "healer archetype", and create an inflated ego. Withdrawal of both projections may however ultimately activate the powers of the inner healer in the patients themselves. Jung’s closest colleague, Marie Louise Von Franz, said “the wounded healer IS the archetype of the Self [our wholeness, the God within] and is at the bottom of all genuine healing procedures.” Jungians warn of the dangers of inflation and splitting in the helping professions, involving projection of the 'wounded' pole of the archetype onto the patient alone, with the analyst safely separated off as 'healer'.
Commercial motor vehicles such as cars, vans, trucks, specialist vehicles (such as mobile construction machinery), forklifts, and trailers Private vehicles used for work purposes (the 'grey fleet') Aviation machinery such as aircraft (planes and helicopters) Ships Rail cars Non-powered assets such as generators, tanks, gear boxes, dumpsters, shipping containers, trailers, excavators, and other equipment that can't run on its own power. Fleet (vehicle) management can include a range of functions, such as vehicle leasing and financing, vehicle maintenance, licensing and compliance, supply chain management, accident management and subrogation, vehicle telematics (tracking and diagnostics), driver management, speed management, fuel management, health and safety management, and vehicle re-marketing. Fleet Management is a function which allows companies which rely on transportation in business to remove or minimize the risks associated with vehicle investment, improving efficiency, productivity and reducing their overall transportation and staff costs, providing 100% compliance with government legislation (duty of care) and many more. These functions can be dealt with by either an in-house fleet-management department or an outsourced fleet-management provider. The number of light duty vehicles registered in commercial fleets in Europe as of 2016 was 15 million, and 19.5 million in North America. Even with these record numbers of registration, light duty vehicles represent only 62% of all fleet sales.
Gorgonzola blue cheese takes its name from the village of Gorgonzola in Italy where it was first made. Belonging to the family of Stracchino cheeses, Gorgonzola is a whole milk, white, and "uncooked" cheese. This blue cheese is inoculated with Penicillium glaucum which, during ripening, produces the characteristic of blue-green veins. There are two variants with different odor: natural and creamy Gorgonzola. 63 components in natural Gorgonzola cheese and 52 components in creamy Gorgonzola cheese contribute to odor with 2-nonanone, 1-octen-3-ol, 2-heptanol, ethyl hexanoate, methylanisole and 2-heptanone being the prominent compounds for odor in both cheeses.

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.
Authorization is limited to a small number of countries and covers specific indications such as chronic hepatitis B and vaccine adjuvant use. Availability and labelling differ by jurisdiction.
Most reviews describe it as an immunomodulatory agent with an uncertain clinical effect. They generally call for larger, better-controlled trials before firm conclusions are drawn.
Lyophilized powder is normally kept at minus twenty degrees Celsius or below, in a sealed container, desiccated and away from light. Reconstituted solutions are less stable and are usually refrigerated and used quickly. Repeated temperature cycling should be avoided.
