A descriptor guiding the selection of catalyst supports for ammonia synthesis.

The efforts to increase the active surface area of catalysts led to reduction of metal particle size, down to single metal atoms. This results in increasing importance of support-metal interactions. We demonstrate the mechanisms through which the support influences catalytic activity of nanoclusters: the support electronics, described by the O 2p energy level, and the support surface chemistry, determined by the density of Lewis base sites.

Sepsis Education and Successful Implementation of a Sepsis Recognition and Management Workflow in an Inpatient Pediatric Hematologic Oncologic Unit.

Sepsis is a leading cause of morbidity, mortality, and healthcare utilization for children worldwide. Forty-nine percent of pediatric sepsis patients have an underlying condition rendering them more susceptible to infection. One in six severe sepsis patients has an underlying neoplastic disease and has a 30% higher risk of death compared to other severe sepsis patients.

Identification and stratification of placenta percreta with gynecologic oncologist management.

Objective: Gynecologic oncologist involvement in the surgical team of patients with placenta percreta has shown improved patient outcomes. Yet, stratification of cases is dependent on identification of placenta percreta by ultrasonography which has a poor detection rate. To allow patients to receive optimal team management by pre-operative stratification our objective was to identify the pre-operative characteristics of patients with previously underdiagnosed placenta percreta.

SARS-CoV-2 Main Protease Inhibitors That Leverage Unique Interactions with the Solvent Exposed S3 Site of the Enzyme.

The main protease (M) of SARS-CoV-2 is crucial for the virus's replication and pathogenicity. Its active site is characterized by four distinct pockets (S1, S2, S4, and S1-3') and a solvent-exposed S3 site for accommodating a protein substrate. During X-ray crystallographic analyses of M bound with dipeptide inhibitors containing a flexible -terminal group, we often observed an unexpected binding mode.

Discovery of First-in-Class PROTAC Degraders of SARS-CoV-2 Main Protease.

We have witnessed three coronavirus (CoV) outbreaks in the past two decades, including the COVID-19 pandemic caused by SARS-CoV-2. Main protease (M), a highly conserved protease among various CoVs, is essential for viral replication and pathogenesis, making it a prime target for antiviral drug development. Here, we leverage proteolysis targeting chimera (PROTAC) technology to develop a new class of small-molecule antivirals that induce the degradation of SARS-CoV-2 M.
