Yoda

. A scientist investigating avian influenza stated that he and his colleagues have personal stocks of Tamiflu. Yogurt teaches Lone Star the ways of the "Schwartz" (parody of the Force; "Schwartz" is a common Ashkenazi Jewish surname). This argument lacks face validity, since treatment must begin before such tests results would be available anyway. In the Mel Brooks movie Spaceballs, the character Yogurt, who is played by Mel Brooks himself, is an obvious spoof on Yoda, but is also considered to be a spoof on Obi-Wan Kenobi. A fourth purported problem is that the H5N1 virus can be reliably diagnosed only in a small number of labs around the world; therefore, there is no way for home users to know whether flu-like symptoms are the result of avian flu or a more benign ailment. The footage showed Yoda denying the allegations, and then being shown in a videotape using cocaine and making indecent sexual proposals to a young Jedi student. [22][23].

Dave Chappelle did a Parody on Chappelle's Show that accused the Jedi Masters of sexually assaulting their traineees, featuring Yoda as a prime offender. However, sophisticated criminals could produce convincing fake packaging in the future. Todd Downing parodies Ricky Martin's "Livin' La Vida Loca" with the song "Livin' La Vida Yoda." More recently, "The Great Luke Ski" parodied the song "YMCA" by the Village People with a version titled "Y.O.D.A." included on the albums Fanboys ‘n Da Hood (1996) and Carpe Dementia (1999). Roche officials know of only one instance of counterfeit Tamiflu appearing outside of the United States: incorrectly-labeled pills found in Holland, which contained only Vitamin C and lactose. The comedy musician "Weird Al" Yankovic parodied the song "Lola" by the Kinks with a remake titled "Yoda", included on the album Dare to Be Stupid (1985). The packages were labeled Generic Tamiflu. According to many Lucasfilm reports, Yoda has been redone in CGI for a later release of The Phantom Menace. This edition will most likely be part of a prequel trilogy pack. In December 2005, 53 packages of fake Tamiflu pills were intercepted by the US Customs Service in South San Francisco.

Despite the use of advanced technology, his performance was deliberately designed to match the puppet version, with some "mistakes" made such as the occasional ear-jiggling. This is genuinely a potential problem, but, in the face of a shortage, some individuals may be willing to face such a risk. In Revenge of the Sith his face appears in several big close-ups, demanding highly-detailed CGI work. Another argument is that it would be difficult for home users to determine whether illegally-imported Tamiflu is counterfeit. Rendered with computer animation in Attack of the Clones and Revenge of the Sith, Yoda appeared in ways not previously possible, including his participation in elaborate fight scenes. Many stockpilers will only have ten 75 mg pills (the current recommended dosage for oseltamivir), but this may be insufficient for the treatment of H5N1 (de Jong 2005). He was computer-generated for two distant shots, but remained mostly a puppet. In the New England Journal of Medicine, Moscona (2005) argues that the use of personal stockpiles of oseltamivir could result in the administration of low dosages, allowing for the development of drug-resistant virus strains.

In The Phantom Menace, he was redesigned to look younger. Ethical arguments are sometimes made: Why should affluent people (or nations) have preferred access to antiviral medications? Illegal importation may divert the drug from poorer countries where the risk of avian influenza is actually higher. In the original Star Wars trilogy, he is realized as a puppet (controlled by Oz). One argument against individual stockpiling is that limited drugs should be kept for more strategic or ethical deployment, that is, to hard-hit areas, to people in critical roles (e.g., healthcare and government workers), to people vulnerable to seasonal flu, or to people who actually have come down with avian influenza. Yoda is voiced by Frank Oz. Several American states, including Massachusetts and Colorado, have issued advisories strongly discouraging this practice. Yoda's appearance was originally designed by British makeup artist Stuart Freeborn, who based Yoda's face partly on his own and partly on Albert Einstein's, as his eyes are supposedly inspired by the latter. The short supply of Tamiflu has prompted some individuals to stockpile the drug.

Moreover, like Yoda, they were master teachers and devoted their lives to preserving the ways of their martial-arts for the good of mankind. On the other hand, at least one Democratic Senator has criticized Bush for not planning to buy enough anti-viral drugs [21]. Their arts both centered on Aiki and the ever present ki (the Force) in their techniques. Previously, Rumsfeld has been implicated in a racketeering lawsuit involving the FDA approval of the artificial sweetner aspartame [20]. Like Yoda, they were very short; this did not hinder their extraordinary martial ability, however. The rise in Gilead's share prices from $35 to $57 per share will have added between $2.5 million to $15.5 million to Rumsfeld's net worth. Similarly, Gozo, martial-master of Yoshinkan Aikido, stood just under 4'11". Rumsfeld is a former chairman of Gilead, and federal disclosure forms indicate that he owns between $5 million and $25 million in Gilead stock (Schwartz 2005 [19]).

The master swordsman Takeda, standing just under 4'11", earned the nickname Aizu no Kotengu (the little goblin). government's endorsement and planned purchase of oseltamivir, noting Secretary of State Donald Rumsfeld's close ties to Gilead Sciences, rightsholder to the Tamiflu patent. This art, Daito-ryu, is accepted as the primary ancestral art to Aikido. Some commentators (e.g., [18]) question the motives of the U.S. Takeda is credited with introducing the once privately practiced martial-art of the Takeda samurai family to the world. Bush's plan included $1.4 billion for government purchases of anti-viral drugs[17]. Basis for this assumption points to the late Sokaku Takeda and Gozo Shioda. Bush requested Congress to fund $7.1 billion in emergency spending for flu pandemic prepardness (the Senate had already passed an $8.1 billion bill)[16].

The basis for Yoda's character may be derived as a duality between two, since passed, Japanese martial masters. president George W. His food is never named but it is mentioned as a stew, but it is also said there was "stewed tendon" in it. In November, 2005, U.S. Yoda is seen eating in the Clone Wars novel Yoda: Dark Rendezvous. The week before, Thai authorities said they would begin producing oseltamivir by February 2006, claiming that Roche had not patented Tamiflu in Thailand[15]. Yoda is never shown eating what is easily recognizable as a meat product; however, we only see Yoda for a relatively short period of time in the Star Wars films, and in that time, see him eat only twice. On November 9, 2005, Vietnam became the first country to be granted permission by Roche to produce a generic version of oseltamivir[14].

Some have suggested that this is due to the strong empathy he feels with all living beings through the Force. Roche said it would instead send all supplies to China's health ministry[13]. Though he lives in a world teeming with animal life, his choice of food has led some to believe that he adheres to a vegetarian or vegan diet. [10][11][12] Sales were suspended in Hong Kong as well, and on November 8, also in China. When we first meet Yoda, he cooks up a stew of roots and leaves to share with Luke Skywalker. It said that, when distribution resumes in Canada, the remaining available drug will be saved for use in high-risk settings like long-term care facilities and hospitals. Another item unique to Master Yoda is a blissl, an instrument similar to a panflute, which he wears around his neck while on Dagobah. In late-October 2005, Roche announced that it was suspending shipments to pharmacies in the United States and Canada until the North American seasonal flu outbreak began, to address concerns about private stockpiling and to preserve supplies for seasonal influenza.

In the Expanded Universe, it is revealed that one of his canes is a gift from the Wookiees, and that his gimer stick cane contains nutrients that can sustain him were he to chew on it. Also in October, it was announced that Roche was in discussions with four generic drug manufacturers about possibly issuing sublicenses to increase production. When not actively using the Force, the elderly Yoda walks with a cane. Cipla argues that it can legally sell oseltamivir to India and 49 other less-developed countries, possibly as early as January 2006. This is due to the fact that once translated into Italian, Yoda's manner of speaking is very close to the Sardinian accent that in Italy is considered humorous, even slightly ridiculous. Most patent laws allow governments to authorize supply from generic companies, subject to remuneration to patent owners to address public health problems, including emergencies, although Roche has annouced its intention to remain the sole supplier of the drug. For Italian fans of the Star Wars series, especially children, Yoda is often referred as "The Sardinian One" or "The One Who Speaks Sardinian". In October 2005, the Indian drug company Cipla announced their plan to begin manufacture of generic oseltamivir without license from Roche.

A typical example of Yoda's speech pattern is from Return of the Jedi: "When 900 years old you reach, look as good you will not." This speech pattern has been the source of much parody. Though significant, the quantities stockpiled would not have been sufficient to protect the entire population of these countries. In linguistic typology this is the "Object Subject Verb" format. In response to the epidemic, various governments – including those of the United Kingdom, Canada, United States and Australia – stockpiled quantities of oseltamivir in preparation for a possible pandemic. Yoda speaks "Galactic Basic" in a distinctive manner by placing verbs (and more frequently, auxiliary verbs) after the object and subject. Oseltamivir, otherwise known as Tamiflu, was widely used during the H5N1 avian influenza epidemic in Southeast Asia in 2005. To all of them, the humble Yoda, who offers enlightened leadership, epitomizes the ideals of the Jedi Order; the grandmaster of that august body is widely known as a sage instructor. Veterinary investigation of its use for canine parvo [8] and canine flu [9]is ongoing, but many shelters and rescue groups have reported great success employing Tamiflu in the early stages of these illnesses.

(In the beginning of their training, students may not see eye-to-eye with him, but eventually come to see the significance of his teachings.) Among his colleagues on the Jedi Council, he is known to have a penchant for mischief and practical jokes. Tamiflu appears to be active against canine parvovirus, feline panleukopenia, the canine respiratory complex known as "kennel cough," and the emerging disease dubbed "canine flu", an equine virus that began affecting dogs in 2005. To his students, the elfin Yoda can appear as either very strict or like a grandfather, testing them to mental and physical extremes one moment and showing warmth the next. In addition, quinic acid, derived from the bark of the cinchona tree of Zaire, is a potential alternative base material for the production of oseltamivir. These skills, in particular, show a far more profound knowledge of the Force than most Jedi Masters or Sith Lords of his time possess. Other potential sources of shikimic acid include the ginko tree. He can purge dark side manifestations through the use of Force Light and feel the deaths of individual people and can identify them. An alternative method for production of the acid involves fermentation of genetically-modified bacteria.

Yoda is even able to use Battle Meditation to win battles by lifting the morale of thousands of companions while simultaneously dampening the spirits of thousands of his opponents. Some academic experts and other drug companies are disputing the difficulty of producing shikimic acid by means other than star anise extraction. Master Yoda can dissipate and deflect Force Lightning, telekinetically lift enormous objects, including an X-wing starfighter, and use Force Push to an untold degree. The northern Vietnamese province of Lang Son has 80 km² of star anise.[7]. Yoda is a great contributor to the highest level of Jedi strategy, and is also a worldly diplomat comparable to Windu. Ninety percent of the harvest is already used by Roche in making Tamiflu. He is an exceptional swordsman, displaying amazing speed and dexterity, leaping through the air and twirling as he batters at an opponent's defenses. Thirteen grams of star anise make 1.3 grams of shikimic acid, which can be made into 10 Tamiflu capsules.

His mastery in Form IV Ataru lightsaber combat enables him to overcome the limitations of his height and reach. The shikimic acid is extracted from the seeds in a ten-stage manufacturing process. Yoda, having mastered all seven forms of lightsaber combat, is considered one of the best duelists in the Jedi Order of his day; Jedi Master Mace Windu seems to be the only Jedi who can equal Yoda in that regard. Star anise is grown in four provinces in China and harvested between March and May. Later that night, Luke sees his father's spirit looking at him with pride and gratitude, in the company of Obi-Wan Kenobi and their once and future master, Yoda. A shortage of star anise is one of the key reasons why there is a worldwide shortage of Tamiflu (as at 2005). Anakin dies in his son's arms as the Empire crumbles around them. According to Roche, the major bottleneck in oseltamivir production is the availability of shikimic acid, which cannot be economically synthesized and is only effectively isolated from Chinese star anise, an ancient cooking spice; although most autotrophic organisms produce shikimic acid, the isolation yield is low.

When the Emperor tries to kill Luke with Force lightning, Vader redeems himself, and once again becomes Anakin Skywalker, by killing his master to save his son. (See Pandemic Fears, below). Yoda's teachings eventually save Luke from giving in to his anger and falling to the dark side; he remembers to control his feelings just as he is seconds away from killing Vader and becoming the Emperor's new apprentice. In early-2005, Roche announced a production shortage. Every single death before and after occurs violently and unnaturally. (2004) all appeared within individual children after treatment with oseltamivir - the children did not catch the resistant strains in human-to-human transmission. Yoda then dies at the age of 900 and becomes "one with the Force." Yoda's death is unique within the Star Wars universe as he is the only character to die peacefully from natural causes. It is worth noting that the oseltamivir-resistant strains detected by Kiso et al.

When Luke returns to Dagobah in 4 ABY (Return of the Jedi), Yoda, sick and greatly weakened by old age, informs Luke that he has completed his training but will not be a Jedi until he defeats his father, Darth Vader. Second, the development of a robust, resistant virus strain appears to be less likely (Ward et al., 2005). Luke promises to return to complete his training. First, these drugs work on a broader spectrum of influenza strains. Prior to finishing his training, however, Luke chooses to leave Dagobah in order to confront Darth Vader and save his friends from the Empire's grasp at Bespin. The lack of variation in neuraminidase gives two advantages to oseltamivir and zanamivir, the drugs that target that enzyme. After initial reluctance, Yoda agrees to teach him in the ways of the Force. This means that there are relatively few variations, and there is also evidence that variations that do occur tend to be less "fit." Thus, mutations that convey resistance to oseltamivir may also tend to cripple the virus by giving it an otherwise less-functional enzyme.

22 years after Yoda's exile, in 3 ABY (The Empire Strikes Back), Luke Skywalker arrives at Dagobah to seek Yoda's guidance after being told by the ghost of Obi-Wan Kenobi, who died during a duel with Darth Vader in A New Hope. The genetic sequence for the neuraminidase enzyme is highly conserved across virus strains. Yoda does not appear and isn't even mentioned in A New Hope. Kiso et al. (2004) suggest that "a higher prevalence of resistant viruses should be expected" during a pandemic. Yoda then retreats to Dagobah, a swampy and deserted planet, patiently waiting for a new hope. Resistance is of concern in the scenario of an influenza pandemic, since resistance is more likely to develop due to the potentially longer duration of infection by novel viruses. As we know from later films, this strategy certainly pays off. Moscona (2005) gives a good overview of the resistance issue, and says that personal stockpiles of Tamiflu could lead to under-dosage and thus the emergence of resistant strains of H5N1.

In addition, the twins' anonymity would be more difficult to protect if the Sith were to discover the remaining Jedi Knights before Luke and/or Leia were ready. They also note that the recommended dosage of oseltamivir does not always completely suppress viral replication, a situation that could favor the emergence of resistant strains. Other than the ancient Jedi Master, only the Organas, the Lars, and Obi-Wan know of their placement (it is unlikely that the Lars were fully aware of Leia's existence, however.) Originally, Obi-Wan wants to have both Yoda and himself take one child each to separate spots and train the children in the ways of the Force, but Yoda realizes that there are other ways to learn discipline than just Jedi training, and that Luke and Leia will need to be trained differently if they are going to defeat the Empire. They suggest that the emergence of a resistant strain may be associated with a patient's clinical deterioration. He is also instrumental in deciding the fate of the Skywalker children after Padmé dies in childbirth, recommending that Luke and Leia be hidden from Darth Vader and his Emperor in unsuspecting and remote locations. (2005) describe resistance development in two more Vietnamese patients suffering from H5N1, and compare their cases with six others. Although this is given little attention in the film, in the novelization it is revealed that Yoda actually becomes Padawan to the deceased Jedi Master's Force ghost, learning the secret of immortality from him and passing it onto Obi-Wan. de Jong et al.

At the end, it is revealed that Yoda has been in contact with Qui-Gon's spirit. She was being treated with oseltamivir at time of detection (Le et al., 2005; World Health Organization, 2005). His transformation into a fearsome cyborg serves as a grim fulfillment to Yoda's words to Obi-Wan upon learning of Anakin's fall from grace: "The boy you trained, gone he is, consumed by Darth Vader.". High-level resistance has been detected in one girl suffering from H5N1 avian influenza in Vietnam. Anakin, meanwhile, loses his limbs and nearly burns to death while battling Obi-Wan; these injuries cost him much of his Force-potential, and the cybernetic enhancements Palpatine administers to save his life render him (seemingly) less than human. Third, the dosage regimen in Japan is different from that of other nations, and some children may have been given a suboptimal dosage of oseltamivir. Yoda then goes into exile to hide from the Empire and to wait for another opportunity to destroy the Sith. Second, Kiso et al. (2004) claim to have used more rigorous detection techniques than previous studies.

With Clone Troopers about to arrive and the Sith's near-destruction of the Jedi Order, Yoda is weakened and realizes that he cannot defeat Palpatine. First, children typically have a longer infection period, giving a longer time for resistance to develop. Yoda, unable to maintain his grasp, falls to the floor of the Senate chamber. Several explanations were proposed by the authors of the studies for the higher-than-expected resistance rate detected. Both Masters are able to grasp the edge of nearby Senate pods, with Palpatine barely managing to hold on. This rate was similar to another study where resistant isolates of H1N1 influenza virus were found in 16.3% of another cohort of Japanese children (Ward et al., 2005). Just as it seems that Yoda is about to gain the upperhand however, the fight ends in a stalemate, an explosion caused by the clash of energies hurling Palpatine and Yoda apart. Mutant H3N2 influenza A virus isolates resistant to oseltamivir were found in 18% of a group of 50 Japanese children treated with oseltamivir (Kiso et al., 2004).

Without his lightsaber, Yoda resorts to using his palms to absorb the dark energy, managing to even reflect some of its power back at a surprised Palpatine. Mutations conferring resistance are single amino acid residue substitutions in the neuraminidase enzyme (Ward et al., 2005). Palpatine counters with a barrage of Force Lightning, taking the elderly Jedi Master off guard, and disarming him. The resistance rate reported during clinical trials up to July 2004 was 0.33% in adults, 4.0% in children, and 1.26% overall. As Palpatine lands, Yoda reappears suddenly with a Force Jump, brandishing his lightsaber. As with other antivirals, resistance to the agent was expected with widespread use of oseltamivir, though the emergence of resistant viruses was expected to be less frequent than with amantadine or rimantadine. In an attempt to end the contest, Palpatine takes the higher ground, and uses the Force to hurl heavy Senate pods at Yoda, who in turn deftly dodges most of them, and sends one back at Palpatine, forcing the latter to jump to a lower level. Roche has other routes to Tamiflu that do not involve the use of (−)-shikimic acid as a chiral pool starting material, such as a Diels-Alder route involving furan and ethyl acrylate or an isophthalic acid route, which involves catalytic hydrogenation and enzymatic desymmetrization.

The fight seems evenly matched between the two patriarchs of both sides of the Force, with neither Form IV master able to overcome the other. It is noted that the synthesis avoids the use of potentially explosive azide reagents and intermediates; however, the synthesis actually used by Roche uses azides. Subsequently, Yoda battles Palpatine in a titanic struggle that wrecks the Senate building. The final product is obtained in high purity (99.7%) and an overall yield of 17-22% from (−)-shikimic acid. Yoda refuses, saying, "To fight this Lord Sidious, strong enough you are not.". Finally, deallylation as above, yielded the freebase of oseltamivir, which was converted to the desired oseltamivir phosphate by treatment with phosphoric acid. Kenobi wants to switch opponents, as he would rather not have to fight with his beloved pupil. Selective acylation with acetic anhydride (under buffered conditions, the 5-amino group is protonated owing to a considerable difference in pK_a, 4.2 vs 7.9, preventing acetylation) yields the desired N-acetylated product in crystalline form upon extractive workup.

Upon discovering a holographic recording revealing Anakin as the assassin, Yoda sends Kenobi to kill his former Padawan. Acidic hydrolysis then removed the imine. This gives him ample warning, and he swiftly kills the clone troopers sent to dispatch him, escapes with the help of Wookiee leaders Tarfful and Chewbacca, and returns to Coruscant, where he and Obi-Wan fight their way into the Jedi Temple to stop a trap for any Jedi who also survived Order 66. With the librated methanesulfonic acid, the aziridine opens cleanly to yield a diamine that immediately undergoes a second transimination. He feels the deaths of each of the Jedi as they are cut down by the very troops they led. Mesylation, followed by removal of the solid byproduct triethylamine hydrochloride, results in an intermediate that was poised to undergo aziridination upon transimination with another equivalent of allylamine. When Palpatine, now self-appointed Emperor of the Galactic Empire, implements Order 66, Yoda is on Kashyyyk, overseeing the battle between the Separatist forces and a combined command of clone troopers and Wookiees. The aminoalcohol was converted directly to the corresponding allyl-diamine in an interesting cascade sequence that commences with the unselective imination of benzaldehyde with azeotropic water removal in methyl tert-butyl ether.

For all his mastery of the Force, however, Yoda does not foresee Anakin's fall to the dark side of the Force. Reduction on palladium, promoted by ethanolamine, followed by acidic workup yielded the deprotected 1,2-aminoalcohol. Yoda uses his incredible sensitivity and power with the Force to sense the Sith Lord's presence, finally concluding that Sidious is someone within Palpatine's inner circle. The water-immiscible solvents methyl tert-butyl ether and acetonitrile are used to simplify the workup procedure, which involved stirring with 1 M aqueous ammonium sulfate. It is at about this time that Yoda leads the Council in pursuing the mysterious Sith Lord Darth Sidious. Using the inexpensive Lewis acid magnesium bromide diethyl etherate (commonly prepared fresh by the addition of magnesium turnings to 1,2-dibromoethane in benzene:diethyl ether), the epoxide is opened with allyl amine to yield the corresponding 1,2-amino alcohol. They know that to give him the rank of Master will also give him a vote in all Council matters, and would be the same as giving Palpatine a vote in the Council — something they were not willing to allow. The corresponding epoxide is formed under basic conditions with potassium bicarbonate.

Yoda and Mace Windu continue to be powerful forces in the young Jedi's ascension in the order, as they deny him the rank of Jedi Master. Reductive opening of the ketal under modified Hunter conditions (JOC 1993, 58, 6756) in dichloromethane yields an inseparable mixture of isomeric mesylates. Again, the Council is hesitant about Anakin's temperament but acquiesces to the request. The 3,4-pentylidene acetal mesylate is prepared in three steps: esterification with ethanol and thionyl chloride; ketalization with para-toluenesulfonic acid and 3-pentanone; and mesylation with triethylamine and methanesulfonyl chloride. In 19 BBY (Revenge of the Sith), Chancellor Palpatine, who by now has near-absolute power in the Galactic Senate, appoints Anakin to the Jedi Council as his own representative. The synthesis commences from naturally available (−)-shikimic acid. Although seemingly frail, the ancient Yoda demonstrates a legendary mastery of lightsaber combat (Form IV lightsaber combat, known for using the Force to achieve extreme acrobatics - see the seven forms of lightsaber combat). The reported azide-free Roche synthesis of tamiflu is summarized graphically below:.

This confrontation ends with Dooku narrowly escaping by threatening Yoda's injured comrades Anakin and Obi-Wan. However, it is known that one adverse reaction added to the Japanese list was haemorrhagic Colitis (bloody diarrhoea)[6].. At the climax of the battle, Yoda duels with Separatist leader and Sith Lord Count Dooku, who was once Yoda's Jedi apprentice. The authors of this section have yet to find Japan's actual listing of adverse reactions linked to oseltamivir. He leads the group which rescues Obi-Wan, Anakin and Padmé Amidala from execution at the hands of the Confederacy of Independent Systems, aka the Separatists. They did recommend adding a warning to prescription information regarding possible rashes. In 22 BBY (Attack of the Clones), Yoda is a key Republic general at the Battle of Geonosis, when the clone trooper Army of the Republic is first deployed. The Committee stated that there was insufficient evidence to claim a causal link between oseltamivir use and the deaths of 12 Japanese children (only two from neurological problems).
