Perimortem caesarean section in COVID-19 era.

Cardiac arrest in pregnancy is very rare. Various methods have been proposed to return spontaneous circulation and prevent mortality, such as Perimortem Caesarean Section (PMCS). Since 2019, the COVID-19 pandemic has added to the difficulty in decision making and performing PMCS.

Knowledge, attitudes, and practices among Indonesian urban communities regarding HPV infection, cervical cancer, and HPV vaccination.

Background: Few studies explored Indonesian understanding of cervical cancer (CC) and the human papillomavirus (HPV) vaccination. We aimed to investigate the association between knowledge, attitudes, and practices (KAP) and socio-demographical influences related to HPV, CC, and vaccination among Indonesian urban citizens.

Methods: We conducted an online survey during March 2020-August 2021 using the Snowball sampling technique.

Cooperative Intramolecular Hydrogen Bonding Strongly Enforces -Peptoid Folding.

Sequence-defined peptoids, or -substituted glycines, are an attractive class of bioispired polymer due to their biostability and efficient synthesis. However, the design of folded peptoids with precise three-dimensional structures has been hindered by limited means to deterministically control backbone conformation. Peptoid folds are generally destabilized by the / backbone-amide isomerization, and few side-chains are capable of enforcing a specific amide conformation.
