Inpatient Gastroenterology Consults Have Little Utility Before Transesophageal Echocardiograms in a Prospective Cohort Study.

Introduction: Despite the well-documented safety of transesophageal echocardiograms (TEEs), inpatient gastroenterology (GI) services are called to clear patients for the procedure when they have GI symptoms or comorbidities ranging from mild to clinically significant. We aimed to assess the clinical utility of such consults in preventing TEE complications.

Methods: We performed a prospective cohort study of all inpatients at our institution who had a TEE ordered from 7/1/2021 through 7/1/2022.

Dab2 (Disabled-2), an adaptor protein, regulates self-renewal of hair follicle stem cells.

Disabled 2 (Dab2), an adaptor protein, is up regulated in the hair follicle stem cells (HFSCs); however, its role in any tissue stem cells has not been studied. In the present study, we have reported that Dab2 conditional knockout (Dab2-cKO) mice exhibited a delay in the HF cycle due to perturbed activation of HFSCs. Further, Dab2-cKO mice showed a reduction in the number of HFSCs and reduced colony forming ability of HFSCs.

In Situ Monitoring of Competitive Coformer Exchange Reaction by H MAS Solid-State NMR.

In a competitive coformer exchange reaction, a recent topic of interest in pharmaceutical research, the coformer in a pharmaceutical cocrystal is exchanged with another coformer that is expected to form a cocrystal that is more stable. There will be a competition between coformers to form the most stable product through the formation of hydrogen bonds. This will cause destabilization of the pharmaceutical products during processing or storage.
