3,4-Dihydroxyphenylacetic acid (DOPAC) is a metabolite of the neurotransmitter dopamine. Dopamine can be metabolized into one of three substances. One such substance is DOPAC. Another is 3-methoxytyramine (3-MT). Both of these substances are degraded to form homovanillic acid (HVA). Both degradations involve the enzymes monoamine oxidase (MAO) and catechol-O-methyl transferase (COMT), albeit in reverse order: MAO catalyzes dopamine to DOPAC, and COMT catalyzes DOPAC to HVA; whereas COMT catalyzes dopamine to 3-MT and MAO catalyzes 3-MT to HVA. The third metabolic end-product of dopamine is norepinephrine (noradrenaline).DOPAC can be oxidized by hydrogen peroxide, leading to the formation of toxic metabolites which destroy dopamine storage vesicles in the substantia nigra. This may contribute to the failure of levodopa treatment of Parkinson's disease. A MAO-B inhibitor such as selegiline or rasagiline can prevent this from happening.It can also be found in the bark of Eucalyptus globulus.This product has been synthesized (52% yield) from 4-hydroxyphenylacetic acid via aerobic biotransformation using whole cell cultures of Arthrobacter protophormiae.

3,4-Ethylidenedioxyamphetamine (EIDA) is a substituted derivative of 3,4-methylenedioxyamphetamine (MDA), which was developed by David Nichols and coworkers, in the course of research to determine the bulk tolerance around the benzodioxole portion of the MDA molecule. EIDA was found to produce similar effects to MDA in animals but with less than half the potency, while the isopropylidinedioxy derivative (IPIDA, IDA) did not substitute for MDA and instead had sedative and convulsant effects. This shows limited bulk tolerance at this position and (as with 2C-G-5) makes it likely the activity of EIDA will reside primarily in one enantiomer, although only the racemic mix has been studied as yet.

In Major League Baseball (MLB), the 3,000 strikeout club is the group of pitchers who have struck out 3,000 or more batters in their careers. Walter Johnson was the first to reach 3,000, doing so in 1923, and was the only pitcher at this milestone for 50 years until Bob Gibson recorded his 3,000th strikeout in 1974. In total, 16 pitchers have reached 3,000 strikeouts with John Smoltz, the most recent club member, joining in 2008. Steve Carlton and Randy Johnson are the only left-handed pitchers in this group. Randy Johnson was the quickest pitcher to 3,000 strikeouts, taking fewer games pitched or innings pitched than any other pitcher. César Gerónimo is the only player struck out by two different pitchers for their 3,000th strikeout, first by Gibson in 1974 and then Nolan Ryan in 1980. The Chicago Cubs are one of two franchises to see multiple pitchers record their 3,000th strikeout on their roster, first Ferguson Jenkins in 1982 and then Greg Maddux in 2005. The Minnesota Twins also had two pitchers reach the milestone with their team – Walter Johnson joined the club while the franchise was called the Washington Senators, then Bert Blyleven joined in 1986 with the team in Minnesota. Ten 3,000 strikeout pitchers are also members of the 300 win club. Seven pitchers from this club were named amongst the one hundred greatest players in MLB history as part of the All-Century Team, four of whom were eventually voted as starters for the team by fan vote.Membership in the 3,000 strikeout club is often described as a guarantee of eventual entry into the Baseball Hall of Fame. Randy Johnson, Pedro Martínez, and John Smoltz are the most recently elected individuals, all voted in during 2015 balloting. Of the sixteen eligible members of the 3,000 strikeout club, fourteen have been elected to the Hall. The two who have appeared on a Hall of Fame ballot but have not yet been elected, Roger Clemens and Curt Schilling, both made their first appearances on the ballot for the 2013 elections. Each received only about half of the total votes needed for induction, with Schilling earning slightly more votes than Clemens. Clemens' future election is seen as uncertain because of his alleged links to use of performance-enhancing drugs (PEDs). The current and near-future eligibility of many players linked to PED use, combined with voting restrictions in Hall of Fame balloting, has been cited as the source of a "backlog" in future Hall elections. Eligibility requires that a player has "been retired five seasons" or deceased for at least 6 months.

The 3,000 mile myth refers to a common belief, particularly in the United States, that all motor vehicles should have their motor oil changed at least every 3,000 miles (4,800 km) to maintain their car engine. Efforts are under way to convince the public that this is not necessary and that people should follow the advice given in their owner's manual rather than the advice of oil-change businesses. With modern synthetic oils and new tests such as BMW's LL ("long life") oil specifications, most current cars can go over 6,000 miles (10,000 km) before needing an oil change. Even most modern conventional oils (also called mineral oils) can take a car engine at least 5,000 miles before needing an oil change.

3,4-Methylenedioxy-N-hydroxyamphetamine (MDOH, MDH, N-hydroxytenamphetamine) is an entactogen, psychedelic, and stimulant of the phenethylamine and amphetamine chemical classes. It is the N-hydroxy homologue of MDA, and the N-desmethyl homologue of MDHMA. MDOH was first synthesized and assayed by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), Shulgin listed the dosage range as 100–160 mg, and the duration as approximately 3–6 hours. He describes MDOH as being very psychedelic and producing increased pleasure in beauty and nature. He also mentioned several negative side effects also seen with MDMA ("Ecstasy") such as difficulty urinating and internal dryness.

3+Share, also known simply as 3+ or 3 Plus, was a pioneering file and print sharing product from 3Com. Introduced in the early 1980s, 3+Share was competitive with Novell's NetWare in the network server business throughout the 1980s. It was replaced by the joint Microsoft-3Com LAN Manager in 1990, but 3Com exited the server market in 1991.In 1984, Microsoft announced MS-Net, a framework for building multitasking network servers that ran on top of single-tasking MS-DOS. MS-Net implemented only the basic services for file and print sharing, and left out the actual networking protocol stack in favor of a virtual system in the form of IBM's NetBIOS. Vendors, like 3Com, licensed the MS-Net system and then added device drivers and other parts of the protocol stack to implement a complete server system.In the case of 3+Share, 3Com based their networking solution on the seminal Xerox Network Systems (XNS), which 3Com's CEO Robert Metcalf had helped design. XNS provided the networking protocol as well as connections to the underlying Ethernet hardware it ran on, which Metcalf had also helped design. They also modified MS-Net's servers to produce what they called EtherShare and EtherPrint protocols, which could be accessed with any MS-DOS computer that had the MS-Net client software installed.Internally, 3+Share had a network stack, file and print server modules, disk caching, user handling and more, all running simultaneously inside the DOS memory space. Because they were not limited by the PC memory map, 3+Share could support a megabyte or so of flat memory, breaking the x86 PC's 640 kByte barrier. This was a large amount of RAM for the time.They later added the XNS Name Service, which mapped network addresses to human-readable names and allowed users to look up devices by looking for strings like "3rd floor printer". Name services were part of the IBM-created NetBIOS in MS-Net, but Microsoft had left those commands out of the server, and it was common for 3rd party implementations like 3+ to add these sorts of services back in. A significant problem with this was that the name service entries could not be synchronized between departmental or enterprise deployments.3Com soon partnered 3+Share with dedicated server hardware called the 3Server, a combination which can be seen to be the first network-attached storage system.3Com and Microsoft jointly developed LAN Manager 2.0 as a successor to 3+Share, a product which was introduced in 1990. 3Com soon lost interest in the network software market, handing over its LAN Manager product (now called 3+Open) as well as its intellectual property to Microsoft in 1991. This work was absorbed into Microsoft and IBM's Server Message Block protocol, which is still used today.3+Share client drivers uses less memory than corresponding ones for LAN Manager.3+Share uses a primitive security mechanism in which the client's security level access is stored in the client's RAM. By simply changing one byte, complete control of the entire system will be gained. The security flaw was known by the manufacturer at the time the product were on the market, but not corrected.Some of the client utilities:3File (3F.EXE) - Managing file sharing3Name (3N.EXE) - Managing name space

The three-base periodicity property in the field of Genomics is a property that is characteristic of protein-coding DNA sequences. The existence of this property can be shown by performing Fourier analysis on signals derived from segments of DNA sequences. Because of its predictive power, it has been used as a preliminary indicator in gene prediction.DNA sequences are inherently signals as they are functions of an independent variable, position on the sequence. Thus, signal processing methods can be applied to them after the symbolic string is properly mapped to one (or more) numerical sequences. The reason for this periodicity is not known for sure, and is likely the result of a few interrelated factors.

It is structurally similar to MDA, but without the methyl group at the alpha position.According to Alexander Shulgin in his book PiHKAL, MDPEA appears to be biologically inactive. This is likely because of extensive first-pass metabolism by the enzyme monoamine oxidase. However, if MDPEA were either used in high enough of doses (e.g., 1-2 grams), or in combination with a monoamine oxidase inhibitor (MAOI), it is probable that it would become sufficiently active, though it would likely have a relatively short duration of action. This idea is similar in concept to the use of selective MAOA inhibitors and selective MAOB inhibitors in augmentation of dimethyltryptamine (DMT) and phenethylamine (PEA), respectively.
