Butyl Imidates: Highly Stable and Isolable Synthetic Intermediates.

Imidates are versatile synthetic intermediates that contain ambiphilic reactivity, making them valuable pharmaceutically relevant synthons. Despite their extensive utility, imidates are typically generated in situ rather than isolated due to their inherent instability. This report details a systematic study that led to the discovery of an isolable imidate hydrogen chloride (HCl) salt that exhibits high tolerance to hydrolysis, thereby improving process control and facilitating downstream transformations.

Artificial intelligence assisted risk prediction in organ transplantation: a UK Live-Donor Kidney Transplant Outcome Prediction tool.

Predicting the outcome of a kidney transplant involving a living donor advances donor decision-making donors for clinicians and patients. However, the discriminative or calibration capacity of the currently employed models are limited. We set out to apply artificial intelligence (AI) algorithms to create a highly predictive risk stratification indicator, applicable to the UK's transplant selection process.

Arrhythmia Burden in Congenitally Corrected Transposition of the Great Arteries (cc-TGA): Does Treatment Pathway Matter?

Background: There is limited data comparing arrhythmia burden amongst patients with congenitally corrected transposition of the great arteries (cc-TGA) undergoing anatomic repair (AR), physiologic repair (PR), and non-surgical management (NS).

Objective: To examine the difference in rate of brady- and tachyarrhythmias amongst patients with cc-TGA stratified by treatment pathway.

Methods: A retrospective cohort study was conducted including all patients with cc-TGA followed at Cleveland Clinic Children's (1995-2021).

Ancient genomics support deep divergence between Eastern and Western Mediterranean Indo-European languages.

The Indo-European languages are among the most widely spoken in the world, yet their early diversification remains contentious. It is widely accepted that the spread of this language family across Europe from the 5th millennium BP correlates with the expansion and diversification of steppe-related genetic ancestry from the onset of the Bronze Age. However, multiple steppe-derived populations co-existed in Europe during this period, and it remains unclear how these populations diverged and which provided the demographic channels for the ancestral forms of the Italic, Celtic, Greek, and Armenian languages.

Monte Carlo modeling of the origin of contaminant electrons on a 0.5T bi-planar Linac-MR.

Introduction: In the last decade, hybrid linear accelerator magnetic resonance imaging (Linac-MR) devices have evolved into FDA-cleared clinical tools, facilitating magnetic resonance guided radiotherapy (MRgRT). The addition of a magnetic field to radiation therapy has previously demonstrated dosimetric and electron effects regardless of magnetic field orientation.

Purpose: This study uses Monte Carlo simulations to investigate the importance and efficacy of the magnetic field design in mitigating surface dose enhancement in the Aurora-RT, focusing specifically on contaminant electrons, their origin, and energy spectrum.
