Question: Context: Malaria is one of the most devastating infectious diseases in the developing world. Until now, only one candidate malaria vaccine RTS,S/AS01 has shown modest protection in phase 3 trial in African infants. Hence the treatment of malaria still depends on the current chemotherapeutic drugs. Considering the resistance of malaria parasites to almost all used antimalarial drugs, aiming at multi-targets rather than a single target will be a more promising strategy. Previous studies have shown that myricetin and fisetin exhibited in vitro antimalarial activity against Plasmodium falciparum, but very little research focused on the molecular mechanism for their parasiticidal activity. The cysteine protease falcipain-2 and aspartic protease plasmepsin II have long been considered as important antimalarial drug targets, especially combined inhibition of these two proteases. In this study, we determined that myricetin and fisetin are dual inhibitors of falcipain-2 and plasmepsin II, which might account for their antimalarial properties. Overall, the dual inhibition of falcipain-2 and plasmepsin II by myricetin and fisetin has shed light on a possible mechanism for their antimalarial activity and provided a rationale for further development as antimalarial drugs. 
 Question: RTS S AS01 vaccine was developed to prevent which disease?

Answer: malaria


Question: Context: The tradition of birthday parties started in Europe a long time ago. It was feared that evil spirits were particularly attracted to people on their birthdays. To protect them from harm, friends and family members would come to stay with the birthday person and bring good thoughts and wishes. Giving gifts brought even more good cheer to keep away from the evil spirits. This is how birthday parties began. The following are some countries' birthday traditions: Canada---Putting butter on the nose. In Atlantic Canada, the birthday child's nose is put butter on for good luck. China---Noodles for lunch. The birthday child pays respect to his / her parents and receives a gift of money. Friends and relatives are invited to lunch and noodles are served to wish the birthday child a long life. England---Money cakes. Certain symbolic objects are mixed into the birthday cake as it is being prepared. If your piece of cake has a coin in it, you will be rich. Ireland---Birthday bump . The birthday child is lifted upside down and " bumped" on the floor for good luck. Italy---Pulling ears. The child's ears are pulled as many times as how old he / she is turning. Japan---New clothes. The birthday child wears new clothes to mark the occasion. New Zealand---Birthday claps. After the candles are hit, the happy birthday song is sung loudly and often out of tune and then the birthday person receives a clap for each year he / she has been alive and then one for good luck. The United States---Cake, candles and the birthday song. A cake is made, and candles are put on top based on how old the person is.
