Engineering of Rieske dioxygenase variants with improved cis-dihydroxylation activity for benzoates.

Rieske dioxygenases have a long history of being utilized as green chemical tools in the organic synthesis of high-value compounds, due to their capacity to perform the cis-dihydroxylation of a wide variety of aromatic substrates. The practical utility of these enzymes has been hampered however by steric and electronic constraints on their substrate scopes, resulting in limited reactivity with certain substrate classes. Herein, we report the engineering of a widely used member of the Rieske dioxygenase class of enzymes, toluene dioxygenase (TDO), to produce improved variants with greatly increased activity for the cis-dihydroxylation of benzoates.

Understanding the financial aspects of digital pathology: A dynamic customizable return on investment calculator for informed decision-making.

Background: The adoption of digital pathology has transformed the field of pathology, however, the economic impact and cost analysis of implementing digital pathology solutions remain a critical consideration for institutions to justify. Digital pathology implementation requires a thorough evaluation of associated costs and should identify and optimize resource allocation to facilitate informed decision-making. A dynamic cost calculator to estimate the financial implications of deploying digital pathology systems was needed to estimate the financial effects on transitioning to a digital workflow.

Gender differences in prevalence of myocardial infarction in rural West Texans.

Background: Heart disease is the leading cause of death in the United States. Incidence rates of myocardial infarction (MI) in rural West Texas signify a lack of effective, risk-specific prevention programs. The purpose of this study was to identify gender-specific risk factors for MI in rural West Texans.

Advancements in transurethral management of urethral stricture disease.

Purpose Of Review: To explore and report the recent evolution of transurethral management of urethral stricture disease.

Recent Findings: In recent years, new promising techniques in the transurethral management of urethral stricture disease have emerged including adjuvant therapies to direct vision internal urethrotomy, regenerative therapy with buccal mucosa cells and minimally invasive transurethral urethroplasty procedures that avoid skin incisions.

Summary: Although further work is needed, the expanding field of transurethral therapies for urethral stricture disease demonstrates early promising results through a variety of modalities.

A Regulatory Science Initiative to Harmonize and Standardize Digital Pathology and Machine Learning Processes to Speed up Clinical Innovation to Patients.

Unlocking the full potential of pathology data by gaining computational access to histological pixel data and metadata (digital pathology) is one of the key promises of computational pathology. Despite scientific progress and several regulatory approvals for primary diagnosis using whole-slide imaging, true clinical adoption at scale is slower than anticipated. In the U.
