question:
Context: John Strangways, the British Intelligence (SIS) Station Chief in Jamaica, is ambushed, killed, and his body taken by three assassins known as the "Three Blind Mice". In response, MI6 agent James Bond (007) is summoned to the office of his superior, M. Bond is briefed to investigate Strangways' disappearance and to determine whether it is related to his cooperation with the American Central Intelligence Agency (CIA) on a case involving the disruption of Cape Canaveral rocket launches by radio jamming.Upon his arrival at Kingston Airport, a female photographer tries to take Bond's picture and he is shadowed from the airport. He is picked up by a chauffeur, who Bond determines to be an enemy agent. Bond instructs him to leave the main road and, after a brief fight, Bond starts to interrogate the driver, who then kills himself with a cyanide-embedded cigarette.During his investigation Bond sees a picture of a boatman named Quarrel with Strangways. Bond locates Quarrel but finds him to be un-cooperative when he interviews him. Bond also recognises Quarrel to have been the driver of the car that chased him from the airport. Bond follows Quarrel and is about to be beaten by him and a friend when the fight is interrupted by the man from the airport who has been following Bond: he reveals himself to be CIA agent Felix Leiter and that not only are the two agents on the same mission, but also that Quarrel is helping Leiter. The CIA has traced the mysterious radio jamming of American rockets to the Jamaica vicinity, but aerial photography cannot see the exact location of its origin. Quarrel reveals that he has been guiding Strangways around the nearby islands to collect mineral samples. He also tells about the island of Crab Key, owned by the reclusive Dr. No, who operates a bauxite mine which is rigorously protected against trespassers by an armed security force and low-scan radar.After finding a receipt in Strangways' house about mysterious rocks naming, Professor R.J. Dent, Bond meets with Dent who says he had assayed the samples for Strangways and determined them to be ordinary rocks. This visit makes Dent wary and he takes a boat to Crab Key where Dr. No expresses displeasure at Dent's failure to kill Bond and orders him to try again, this time with a large venomous spider. Bond survives and kills the spider.Bond becomes friendly with Strangways' secretary, Miss Taro and agrees to meet her at her home in the hills above Kingston. While driving there, Bond is attacked by several men driving a large hearse. He is able to outmaneuver them and the hearse is run off the mountain road and explodes. When Bond shows up at Taro's house, she's surprised to see him, a fact that Bond notes easily. She goes into her bedroom and talks on the phone to her boss, who tells her to keep Bond occupied for a few hours. Bond and Taro spend that time in bed.Bond makes a phone call, ostensibly asking for a taxi but actually talking to the local police, who show up soon after and arrest Taro. Bond then sets a trap for Dent and waits for him to show. Dent steals into the bedroom and fires several silenced shots into the bed, which Bond rigged to look like it was occupied. Bond forces Dent to drop his pistol and begins to interrogate him about Strangways and his radioactive rock samples, which Dent tried to cover up. Dent is able to recover his pistol, finding it empty and Bond coldly shoots him dead.Having detected radioactive traces in Quarrel's boat, where Strangways' mineral samples had been, Bond convinces a reluctant Quarrel to take him to Crab Key. On the beach there, Bond meets the beautiful Honey Ryder, dressed only in a white bikini, who is collecting shells. At first she is suspicious of Bond but soon decides to help him, leading them all inland to an open swamp. After nightfall they are attacked by the legendary "dragon" of Crab Key which turns out to be a flame-throwing armoured vehicle. In the resulting gun battle, Quarrel is incinerated by the flame-thrower whilst Bond and Honey are 
 Question: who finds a receipt?
answer:
bond

Context: The actions of benzodiazepines are due to the potentiation of the neural inhibition that is mediated by gamma-aminobutyric acid (GABA). Practically all effects of the benzodiazepines result from their actions on the ionotropic GABA(A) receptors in the central nervous system. Benzodiazepines do not activate GABA(A) receptors directly but they require GABA. The main effects of benzodiazepines are sedation, hypnosis, decreased anxiety, anterograde amnesia, centrally mediated muscle relaxation and anti-convulsant activity. In addition to their action on the central nervous system, benzodiazepines have a dose-dependent ventilatory depressant effect and they also cause a modest reduction in arterial blood pressure and an increase in heart rate as a result of a decrease of systemic vascular resistance. The four benzodiazepines, widely used in clinical anaesthesia, are the agonists midazolam, diazepam and lorazepam and the antagonist flumazenil. Midazolam, diazepam and flumazenil are metabolized by cytochrome P450 (CYP) enzymes and by glucuronide conjugation whereas lorazepam directly undergoes glucuronide conjugation. CYP3A4 is important in the biotransformation of both midazolam and diazepam. CYP2C19 is important in the biotransformation of diazepam. Liver and renal dysfunction have only a minor effect on the pharmacokinetics of lorazepam but they slow down the elimination of the other benzodiazepines used in clinical anaesthesia. The duration of action of all benzodiazepines is strongly dependent on the duration of their administration. Based on clinical studies and computer simulations, midazolam has the shortest recovery profile followed by lorazepam and diazepam. Being metabolized by CYP enzymes, midazolam and diazepam have many clinically significant interactions with inhibitors and inducers of CYP3A4 and 2C19. In addition to pharmacokinetic interactions, benzodiazepines have synergistic interactions with other hypnotics and opioids. Midazolam, diazepam and lorazepam are widely used for sedation and to some extent also for induction and maintenance of anaesthesia. Flumazenil is very useful in reversing benzodiazepine-induced sedation as well as to diagnose or treat benzodiazepine overdose. 
 Question: Which drug should be used as an antidote in benzodiazepine overdose?
answer:
flumazenil


question:
Context: To evaluate and compare outcomes for patients with vestibular schwannoma (VS) treated in a single institution with linac-based stereotactic radiosurgery (SRS) or by fractionated stereotactic radiotherapy (SRT). One hundred and nineteen patients (SRS = 78, SRT = 41) were treated. For both SRS and SRT, beam shaping is performed by a mini-multileaf collimator. For SRS, a median single dose of 12.5 Gy (range, 11-14 Gy), prescribed to the 80% isodose line encompassing the target, was applied. Of the 42 SRT treatments, 32 treatments consisted of 10 fractions of 3-4 Gy, and 10 patients received 25 sessions of 2 Gy, prescribed to the 100% with the 95% isodose line encompassing the planning target volume. Mean largest tumor diameter was 16.6 mm in the SRS and 24.6 mm in the SRT group. Local tumor control, cranial nerve toxicity, and preservation of useful hearing were recorded. Any new treatment-induced cranial nerve neuropathy was scored as a complication. Median follow-up was 62 months (range, 6-136 months), 5 patients progressed, resulting in an overall 5-year local tumor control of 95%. The overall 5-year facial nerve preservation probability was 88% and facial nerve neuropathy was statistically significantly higher after SRS, after prior surgery, for larger tumors, and in Koos Grade 3. The overall 5-year trigeminal nerve preservation probability was 96%, not significantly influenced by any of the risk factors. The overall 4-year probability of preservation of useful hearing (Gardner-Robertson score 1 or 2) was 68%, not significantly different between SRS or SRT (59% vs. 82%, p = 0.089, log rank). Linac-based RT results in good local control and acceptable clinical outcome in small to medium-sized vestibular schwannomas (VSs). Radiosurgery for large VSs (Koos Grade 3) remains a challenge because of increased facial nerve neuropathy. 
 Question: Which disease can be categorized using the Koos grading system?
answer:

vestibular schwannoma
