Analysis of limited proteolysis-coupled mass spectrometry data.

Limited proteolysis combined with mass spectrometry (LiP-MS) facilitates probing structural changes on a proteome-wide scale. This method leverages differences in the proteinase K accessibility of native protein structures to concurrently assess structural alterations for thousands of proteins in situ. Distinguishing different contributions to the LiP-MS signal, such as changes in protein abundance or chemical modifications, from structural protein alterations remains challenging.

Timing and Patterns of Potentially Salvageable Recurrences Following Stereotactic Body Radiation Therapy for Clinically Localized Prostate Cancer Assessed by Preferential Amino Acid Uptake.

Purpose: 18F-fluciclovine is a radiolabeled amino acid analog that is preferentially taken up by prostate cancer cells. 18F-fluciclovine PET/CT scans are approved for the detection of biochemically recurrent prostate cancer. Stereotactic body radiation therapy (SBRT) is increasingly offered for the treatment of localized prostate cancer.

"It was a good opportunity for us to be in touch with public health": Independent community pharmacists' experiences working with public health before and during COVID-19.

Purpose: Pharmacies have been a significant part of improving population health since before the COVID-19 pandemic. However, little is known about the working relationships between pharmacies and public health entities. This exploratory study describes independent community pharmacists' perceptions during COVID-19 of both pre-existing and newly created relationships with public health.

225 Ac-PSMA-617 Augmentation After Insufficient Response Under 177 Lu-PSMA-617 Radioligand Therapy in mCRPC: Evaluation of Outcome and Safety From a Prospective Registry (REALITY Study).

Background: Even though the introduction of 177 Lu-PSMA-617 RLT represents a major milestone in the treatment of mCRPC, there are still patients who do not respond adequately to this therapy and for whom there are only limited options left. Augmenting 177 Lu-PSMA-617 RLT with the alpha-emitter 225 Ac-PSMA-617 may present an escalating treatment option to increase efficacy. In this study, we aim to evaluate outcome and safety of 225 Ac-PSMA-617 augmentation to 177 Lu-PSMA-617 RLT in patients who present insufficient response to monotherapy with 177 Lu-PSMA-617 RLT.

Subtle signs of atrial cardiomyopathy and left ventricular diastolic dysfunction are associated with reduced cognitive function: results from the Hamburg City Health Study.

Background: Atrial fibrillation is associated with cognitive dysfunction. Atrial cardiomyopathy has been correlated with both entities. We aimed to characterize the association of echocardiographic parameters of atrial cardiomyopathy with cognitive function and cerebral changes.
