Background: The COVID-19 pandemic prompted researchers to develop new ways to design and launch studies and recruit and retain participants. Pregnant women and infants are considered vulnerable populations in research, and families affected by substance use are particularly difficult to recruit and retain. Recruitment for studies involving medical technologies such as MRI can also be difficult due to misconceptions and fear of the technologies.

Antibodies have gained clinical success in the last two decades for the targeted delivery of highly toxic small molecule chemotherapeutics. Yet antibody-drug conjugates (ADCs) often fail in the clinic due to the development of resistance. The delivery of two mechanistically distinct small molecule drugs on one antibody is of increasing interest to overcome these challenges with single-drug ADCs.

Patients with metastatic pancreatic ductal adenocarcinoma survive longer if disease spreads to the lung but not the liver. Here we generated overlapping, multi-omic datasets to identify molecular and cellular features that distinguish patients whose disease develops liver metastasis (liver cohort) from those whose disease develops lung metastasis without liver metastases (lung cohort). Lung cohort patients survived longer than liver cohort patients, despite sharing the same tumor subtype.

The rich diversity of synapses facilitates the capacity of neural circuits to transmit, process and store information. We used multiplex super-resolution proteometric imaging through array tomography to define features of single synapses in mouse neocortex. We find that glutamatergic synapses cluster into subclasses that parallel the distinct biochemical and functional categories of receptor subunits: GluA1/4, GluA2/3 and GluN1/GluN2B.
