Cardiac conduction system regeneration prevents arrhythmias after myocardial infarction.

Arrhythmias are a hallmark of myocardial infarction (MI) and increase patient mortality. How insult to the cardiac conduction system causes arrhythmias following MI is poorly understood. Here, we demonstrate conduction system restoration during neonatal mouse heart regeneration versus pathological remodeling at non-regenerative stages.

Direct specification of lymphatic endothelium from mesenchymal progenitors.

During embryogenesis, endothelial cells (ECs) are generally described to arise from a common pool of progenitors termed angioblasts, which diversify through iterative steps of differentiation to form functionally distinct subtypes of ECs. A key example is the formation of lymphatic ECs (LECs), which are thought to arise largely through transdifferentiation from venous endothelium. Opposing this model, here we show that the initial expansion of mammalian LECs is primarily driven by the in situ differentiation of mesenchymal progenitors and does not require transition through an intermediate venous state.

Prevalence and Incidence of Stress Among UK Dental Students: A Systematic Review and Meta-analysis.

Objective: Dental professionals experience stress daily due to the nature of the excessively demanding working environment in addition to the trust laid upon them by the public. This review aims to evaluate the available evidence on the prevalence and incidence of stress in UK dental students. The paper critically assesses current evidence, shedding light on mental health issues faced by dental healthcare workers.

Ordinal Confidence Level Assignments for Regression Model Predictions.

We present a simple method for assigning accurate confidence levels to molecular property predictions from regression models. These confidence levels are easy to interpret and useful for making decisions in drug discovery programs. We demonstrate their performance using time-split validation with assay data from the Relay Therapeutics internal database.

Development of a qPCR assay for the quantification of canine autosomal DNA recovered from livestock attacks.

The absence of a standardised method to quantify canine DNA recovered from livestock attacks leaves forensic providers without an important quality control step to help support their decision making. Typically used to normalise the amount of DNA for STR amplification, modern forensic DNA quantification approaches use qPCR of target genes and can also include an Internal Positive Controls (IPC) to determine the presence of PCR inhibitors. The co-amplification of livestock DNA alongside canine DNA has meant that previously developed qPCR methods are not suitable for use so a standardised approach is needed.
