Capsicum chinense is thought to have been domesticated in the lowlands east of the Andes Mountains in South America. It is grown in Southeast Asia, but its distribution there remains unknown. We conducted literature, specimen, field, and market surveys of C. chinense in Indonesia to investigate its introduction into Indonesia and to determine its current distribution. One dried specimen collected in 1912 and stored as Capsicum sp. appears to be either C. frutescens or C. chinense. An illustration of C. frutescens in Ochse (1931), which actually appears to be C. chinense, suggests that C. chinense may have been introduced into Indonesia before World War II; however, the distribution of C. chinense in Southeast Asia remains very limited to this today. In Indonesia, C. chinense is distributed widely on at least the three major islands of Java, Kalimantan, and Sulawesi with several morphologically different fruit types; it is used as an ornamental plant as well as a spice. Four species of the genus Capsicum, including C. annuum, C. frutescens, C. pubescens, and C. chinense, are distributed in Indonesia, which suggests that Indonesia has more genetic resources and more potential to breed species of Capsicum than other countries in Southeast and East Asia.

Objective: To assess mechanisms underlying aneurysm formation using a simple electronic circuit model.Materials and Methods: We created a simple circuit model connecting the celiac artery (CA) to the superior mesenteric artery via the pancreaticoduodenal arcade. We retrospectively reviewed 12 patients with true pancreaticoduodenal artery aneurysms (PDAAs) who received open or endovascular treatment between 2004 and 2017. We set the resistance of each artery and organ voltage and calculated flow volume and rate in response to degrees of simulated CA stenosis from 0% to 99.9%.Results: Flow volume rates of the anterior pancreaticoduodenal artery and posterior pancreaticoduodenal artery decreased to zero when CA stenosis increased from 0% to 50% and then increased drastically, at which point flow direction reverted and the flow was up to three times the initial rate. The gastroduodenal artery (GDA) also showed reversed flow with severe CA stenosis. In 12 patients with PDAA, eight presented with a CA lesion, and the other patients presented with comorbidities causing the arteries to be pathologically fragile, such as Marfan syndrome, Behçet’s disease, and segmental arterial mediolysis. All four GDA aneurysms were not accompanied by CA lesions.Conclusion: The mechanism underlying CA-lesion-associated PDAA formation may be partially explained using our model.
