Question: In 278 BC, learning of the capture of his country's capital, Ying, by General Bai Qi of the state of Qin, Qu Yuan is said to have written the lengthy poem of lamentation called ''Lament for Ying'' and later to have waded into the Miluo river in today's Hunan Province holding a rock in order to commit ritual suicide as a form of protest against the corruption of the era.

Answer: In one word, how did Qu Yuan die?

Question: CADASIL is a cerebrovascular disease caused by mutations in the NOTCH3 gene. Most mutations result in a gain or loss of cysteine residue in one of the 34 epidermal growth factor-like repeats in the extracellular domain of the Notch3 protein, thus sparing the number of cysteine residues. To date, more than 130 different mutations in the NOTCH3 gene have been reported in CADASIL patients, of which 95% are missense point mutations. Many polymorphisms have also been identified in the NOTCH3 coding sequence, some of them leading to amino acid substitutions. The aim of the present study was to analyze the NOTCH3 gene in a large group of patients affected by leukoencephalopathy and to investigate the presence of genetic variants. The molecular analysis revealed several nucleotide alterations. In particular, we identified 20 different mutations, 22 polymorphisms, and 8 genetic variants of unknown pathological significance never reported previously. We hope that this NOTCH3 gene mutational analysis, performed in such a significant number of unrelated and related patients affected by leukoencephalopathy, will help in molecular screening for the NOTCH3 gene, thus contributing to enlargement of the NOTCH3 gene variation database.

Answer: Which amino acid residue appears mutated in most of the cases reported with cadasil syndrome?

Question: On 19 April 1918, Detachment Brandenstein took over the town of Lahti. The German troops advanced from the east-southeast via Nastola, through the Mustankallio graveyard in Salpausselka and the Russian garrisons at Hennala. The battle was minor but strategically important as it cut the connection between the western and eastern Red Guards. Local engagements broke out in the town and the surrounding area between 22 April and 1 May 1918 as several thousand western Red Guards and Red civilian refugees tried to push through on their way to Russia. The German troops were able to hold major parts of the town and halt the Red advance. In total, 600 Reds and 80 German soldiers perished, and 30,000 Reds were captured in and around Lahti.

Answer:
Where did the German troops advance through first, Hennala or Nastola?
