An obligate step in the life cycle of HIV-1 and other retroviruses is the establishment of the provirus in target cell chromosomes. Transcriptional regulation of proviruses is complex, and understanding the mechanisms underlying this regulation has ramifications for fundamental biology, human health, and gene therapy implementation. The three core components of the Human Silencing Hub (HUSH) compl...

To investigate atropisomers of non-steroidal glucocorticoid receptor modulator GSK866, a virtual library of substituted benzoic acid analogues was enumerated. Compounds from this library were subjected to a torsion angle scan using Spartan'20 to calculate the torsion rotation energy barrier which identified compounds predicted to be stable as atropisomers. After synthesis of the library, analysis ...

CONCLUSION: Although POCUS provides rapid information in the diagnosis of type A AD, 14% of patients with images available for review had no findings on POCUS. Of the whole cohort, 12% had an ADRS = 0. Further studies are needed to identify an optimal diagnostic pathway for this catastrophic disease.

CONCLUSION: All the first-generation devices achieved good clinical outcomes and retreatment rates in treating ICA sidewall aneurysms. Prospective studies are needed to explore the nuanced differences between these devices in the long term.

CONCLUSIONS: Patients who develop late VT may experience a higher risk of 30-day rehospitalization following hospital discharge for AMI, especially among those with ST-segment-elevation AMI. Larger studies are needed to confirm our findings.

Conformational dynamics of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein (S) mediate exposure of the binding site for the cellular receptor, angiotensin-converting enzyme 2 (ACE2). The N-terminal domain (NTD) of S binds terminal sialic acid (SA) moieties on the cell surface, but the functional role of this interaction in virus entry is unknown. Here, we report...

The scaffold proteins JIP1 and JIP2 intervene in the c-Jun N-terminal kinase (JNK) pathway to mediate signaling specificity by coordinating the simultaneous assembly of multiple kinases. Using NMR, we demonstrate that JIP1 and JIP2 heterodimerize via their SH3 domains with the affinity of heterodimerization being comparable to homodimerization. We present the high-resolution crystal structure of t...
