We designed and synthesized three diacetylene monomers M1-M3 having two NH2 groups. As anticipated, the NH2 groups aided the preorganization of these monomers by N-H…N hydrogen bonding. In the crystals of monomer M1 and M2, the intermolecular N-H…N hydrogen bonding preorganized the diyne units in an orientation suitable for their topochemical polymerization, but in the case of monomer M3, the distance was slightly larger than that recommended for the topochemical reaction.

The effectiveness of the stabilisation/solidification process depends upon a number of factors, the most significant of which are the type of binder, contaminants, and soil undergoing treatment. In accordance with the principles of sustainable construction, alternatives to cement are sought after, with the objective of achieving the lowest environmental impact while maintaining a high level of strength and effective binding of the contaminant. In the study of the stabilisation/solidification of zinc-contaminated loess, incinerated sewage sludge fly ash with reactive magnesia was selected as the binder, and the UCS of the mixtures and microstructure was verified after 28 days of treatment.

- Prenatal exome sequencing (ES) successfully identified both fetal and maternal genetic diagnoses, revealing a shared pathogenic gamma globin variant in a fetus with unexplained anemia and a mother with sickle cell disease (SCD).
- The identified variant, HbF Mission Bay HBG2, is linked to various blood-related conditions, including cyanosis and hemolytic anemia, which generally emerge in infancy but can persist into adulthood.
- In this case, the mother's own symptoms from the variant, such as recurrent hypoxia and methemoglobinemia during pregnancy, occurred alongside the fetus's need for multiple blood transfusions and post-birth methemoglobinemia.
Background: The COVID pandemic led to the transition of residency applications to a virtual format and the expansion of residency programs' virtual presence.
Objective: The objective is to understand what information Obstetrics and Gynecology Residency interviewees prioritize and how influential program websites and social media platforms are.
Study Design: Electronic surveys were sent to fourth-year medical students and OBGYN residents and were available for 6 weeks in spring 2023.
