[Q]: The Battle of al-Qadisiyyah (Arabic: ; transliteration, Ma'rakatu al-Qadisiyyah; Persian: transliteration Nabard-e Qadesiyeh; alternative spellings: Qadisiyya, Qadisiyyah, Kadisiya, Ghadesiyeh), fought in 636, is said to be a decisive engagement between the Arab Muslim army and the Sassanid Persian army during the first period of Muslim expansion.
[A]: On what date did Battle of al-Qādisiyyah end?


[Q]: Lindsay (Ashley C. Williams) and Jenny (Ashlynn Yennie), two American tourists in Germany, are drugged and involuntarily detained by crazed surgeon Dr. Josef Heiter (Dieter Laser) when they seek help at his house after they get a flat tire. The women awake in a makeshift medical ward. They witness Heiter kill a kidnapped truck driver after Heiter informs him he is "not a match". Heiter secures a new male captive, Japanese tourist Katsuro (Akihiro Kitamura). The doctor explains that he is a world-renowned expert at separating Siamese twins, but dreams of making new creatures by sewing people together. He describes in detail how he will surgically connect his three victims mouth-to-anus, so that they share a single digestive system. After Lindsay tries to escape and fails, Heiter explains that he had previously experimented with creating what he called a "three-dog", also joined mouth-to-anus. However, the three-dog died shortly after surgery. Heiter tells Lindsay that one dog tried to escape and that dog became the middle, thus this caused the most pain to the dog and as punishment for her escape attempt, she will become the middle part of his centipede. Heiter performs the surgery, placing Katsuro at the front, Lindsay in the middle and Jenny at the rear. He removes the front teeth of both women and mutilates the buttocks of both Katsuro and Lindsay in order to provide easier access to the rectums, to which he hideously stitches and grafts their mouths. During his procedure, he severs the ligaments within his victims' knees to prevent leg extension, forcing his victims to crawl. He then connects his victims together in a straight line with their mouths surgically attached to the anus of the victim in front of them. Once the operation is complete, Heiter attempts to train his centipede as a pet, often belittling Katsuro with racist insults and beating him with a crop when he becomes rebellious. When Katsuro defecates, Lindsay is forced to swallow his excrement while the doctor watches in delight. However, he eventually becomes irritated after being kept awake by the constant screaming of Katsuro (who, as the front part of the centipede, has his mouth free and is still able to speak) and the realization that Jenny is dying from septicemia. When two detectives, Kranz (Andreas Leupold) and Voller (Peter Blankenstein), visit the house to investigate the disappearance of tourists, Heiter comes up with an idea to add them as replacements for Jenny in a new creation; a four-segment centipede. He offers the two detectives water spiked with sedatives in hopes of knocking the two unconscious. After being given the water, the detectives become suspicious and obtain a search warrant for his home. While the detectives leave Heiter's home, the victims attempt to escape. Katsuro attacks Heiter in the process. Their attempt to escape ultimately fails. Katsuro confesses to the doctor that he deserves his fate because he had treated his own family poorly, then commits suicide by slitting his throat with a glass shard. Upon returning to Heiter's home, the detectives forcefully conduct separate searches as an injured Heiter hides near his swimming pool. Kranz finds the ward along with Heiter's victims. Voller begins to feel ill from the earlier drugging, and Heiter stabs him with the scalpel pulled from his leg during Katsuro's attack. Upon finding Voller dead, Kranz is shot by Heiter with Voller's sidearm. Kranz responds by shooting Heiter in the head before dying. Back in the house, Jenny and Lindsay hold hands as Jenny dies. Lindsay sobs as she is left alone in the house, trapped between her deceased fellow captives. Her fate is left unknown. The film ends with the sounds of her sobbing while the camera pans to the roof of the house.
[A]: what type of poisoning is Jenny dying from?


[Q]: Viroids, satellite RNAs, satellites viruses and the human hepatitis delta virus form the 'brotherhood' of the smallest known infectious RNA agents, known as the subviral RNAs. For most of these species, it is generally accepted that characteristics such as cell movement, replication, host specificity and pathogenicity are encoded in their RNA sequences and their resulting RNA structures. Although many sequences are indexed in publicly available databases, these sequence annotation databases do not provide the advanced searches and data manipulation capability for identifying and characterizing subviral RNA motifs. The Subviral RNA database is a web-based environment that facilitates the research and analysis of viroids, satellite RNAs, satellites viruses, the human hepatitis delta virus, and related RNA sequences. It integrates a large number of Subviral RNA sequences, their respective RNA motifs, analysis tools, related publication links and additional pertinent information (ex. links, conferences, announcements), allowing users to efficiently retrieve and analyze relevant information about these small RNA agents. With its design, the Subviral RNA Database could be considered as a fundamental building block for the study of these related RNAs. It is freely available via a web browser at the URL: [Link]
