Paralogs, arising from gene duplications, increase the functional diversity of proteins. Protein functions in paralog families have been extensively studied, but little is known about the roles that intrinsically disordered regions (IDRs) play in their paralogs. Without a folded structure to restrain them, IDRs mutate more diversely along with evolution. However, how the diversity of IDRs in a paralog family affects their functions is unexplored. Using the RNA-binding protein Musashi family as an example, we applied multiple structural techniques and phylogenetic analysis to show how members in a paralog family have evolved their IDRs to different physicochemical properties but converge to the same function. In this example, the lower prion-like tendency of Musashi-1’s IDRs, rather than Musashi-2’s, is compensated by its higher α-helical propensity to assist their assembly. Our work suggests that, no matter how diverse they become, IDRs could evolve different traits to a converged function, such as liquid-liquid phase separation.

Several species of cephalopods, particularly squid, are present in Danish waters, but neither are they fished commercially nor are they part of the Danes' traditional diet.However, if Danes can eat octopus, squid, and cuttlefish when visiting Southern Europe why do they hesitate to eat Danish cephalopods at home? Cephalopods are a nutritious, healthy, and sustainable source of seafood. Moreover, the populations of all species of cephalopods are globally on the rise in stark contrast to the dwindling traditional fisheries. Eating more of them is a way to a more insightful and sustainable use of the marine food resources. The challenge is how to prepare them into delicious 2 food and how to make the Danish population, the fishermen, and the retailers aware of their great potential and value as sustainable and delicious food. We have combined scientific gastrophysical investigations of various squid preparations with gastronomical design, innovation, development of recipes, and inventive product design to furnish a solid basis for spreading knowledge, appreciation of flavour, and a desire to consume Danish squid in Denmark.

To investigate antiepileptic drugs (AEDs) prescription and pregnancy outcomes in pregnancies with epilepsy in Taiwan between 2004 and 2015. We retrospectively reviewed data from the Taiwanese Registry of Epilepsy and Pregnancy (TREP). The TREP registry is a voluntary prospective cohort registry, which tracks pregnant women with epilepsy and AED prescription throughout pregnancy, delivery, and early childhood development. All TREP pregnancies (n = 318) that had completed questionnaires up until delivery or had had an unsuccessful pregnancy were analyzed. Over 94.7% of women had been prescribed AEDs during pregnancy, with 69.0% and 25.7% having received monotherapy, or polytherapy, respectively. Among live births, 12 (3.9%) reported malformation. Cesarean section rate was reported higher than usual (54.5%). In 2004, 73.3% of AEDs prescribed were 1st generation, with 1st generation prescription rates falling to only 8.3% of total prescribed in 2015. AED polytherapy also fell during the study period (40.0% to 20.0%). Cesarean sections were found to be higher for women over 35 years, who had generalized epilepsy, or had experienced an obstetric complication during pregnancy term. Binary logistic regression revealed that Cesarean section was associated with maternal complications (OR = 5.11, CI 95% = 1.11–23.51, p = 0.036), while malformations were associated with obstetric complication (OR = 20.46, CI 95% = 4.80–87.21, p<0.001). Both AED risk types were not associated with complications or malformations. Our sample provides a unique insight into the women with epilepsy with AED use during pregnancy. Cesarean section rate was observed to be higher than usual, but malformation rates remained low. Results indicate a decrease in both 1st generation AEDs and proportion of patients receiving polytherapy over the study period. Obstetric complications were associated with Cesarean section. Fetal malformations were significantly associated with obstetric complications. AED risk factors were not significantly associated with either complications or malformations.
