Question: Context: After the defeat of several Song armies in the north, Emperor Qinzong wanted to negotiate a truce with the Jin, but he committed a massive strategic blunder when he commanded his remaining armies to protect prefectural cities instead of Kaifeng. Neglecting the importance of the capital, he left Kaifeng defended with fewer than 100,000 soldiers. The Song forces were dispersed throughout China, powerless to stop the second Jurchen siege of the city. The Jin assault commenced in mid December 1126. Even as fighting raged on, Qinzong continued to sue for peace, but Jin demands for territory were enormous: they wanted all provinces north of the Yellow River. After more than twenty days of heavy combat against the besieging forces, Song defenses were decimated and the morale of Song soldiers was on the decline. On January 9, 1127, the Jurchens broke through and started to loot the conquered city. Emperor Qinzong tried to appease the victors by offering the remaining wealth of the capital. The royal treasury was emptied and the belongings of the city's residents were seized. The Song emperor offered his unconditional surrender a few days later. Qinzong, the former emperor Huizong, and members of the Song court were captured by the Jurchens as hostages. They were taken north to Huining , where they were stripped of their royal privileges and reduced to commoners. The former emperors were humiliated by their captors. They were mocked with disparaging titles like "Muddled Virtue" and "Double Muddled". In 1128 the Jin made them perform a ritual meant for war criminals. The harsh treatment of the Song royalty softened after the death of Huizong in 1135. Titles were granted to the deceased monarch, and his son Qinzong was promoted to Duke, a position with a salary. 
 Question: Which happened first, the seizing of the resident's belongings to give to the Jin, or unconditional surrender of the Song emperor?

Answer: belongings of the city's residents


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: Vaginal microbicides for the prevention of HIV transmission may be an important option for protecting women from infection. Incorporation of dapivirine, a lead candidate nonnucleoside reverse transcriptase inhibitor, into intravaginal rings (IVRs) for sustained mucosal delivery may increase microbicide product adherence and efficacy compared with conventional vaginal formulations. Twenty-four healthy HIV-negative women 18-35 years of age were randomly assigned (1:1:1) to dapivirine matrix IVR, dapivirine reservoir IVR, or placebo IVR. Dapivirine concentrations were measured in plasma and vaginal fluid samples collected at sequential time points over the 33-day study period (28 days of IVR use, 5 days of follow-up). Safety was assessed by pelvic/colposcopic examinations, clinical laboratory tests, and adverse events. Both IVR types were safe and well tolerated with similar adverse events observed in the placebo and dapivirine groups. Dapivirine from both IVR types was successfully distributed throughout the lower genital tract at concentrations over 4 logs greater than the EC50 against wild-type HIV-1 (LAI) in MT4 cells. Maximum concentration (Cmax) and area under the concentration-time curve (AUC) values were significantly higher with the matrix than reservoir IVR. Mean plasma concentrations of dapivirine were <2 ng/mL. These findings suggest that IVR delivery of microbicides is a viable option meriting further study. 
 Question: Which infection can be prevented with Dapivirine?

Answer:
hiv
