On-line Inductively Coupled Plasma Mass Spectrometry Reveals Material Degradation Dynamics of Au and Cu Catalysts during Electrochemical CO Reduction.

A significant challenge in commercializing electrochemical CO reduction (COR) is achieving catalyst durability. In this study, online inductively coupled mass spectrometry (ICP-MS) was used to investigate catalyst degradation via nanoparticle detachment and/or dissolution into metal ions under COR operating conditions in 0.1 M KHCO.

Loss of increases type I interferon signalling and reduces pancreatic tumour growth by enhancing immune cell infiltration.

Background: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal forms of cancer, and despite low incidence rates, it remains the sixth leading cause of cancer related deaths worldwide. Immunotherapy, which aims to enhance the immune system's ability to recognize and eliminate cancer cells, has emerged as a promising approach in the battle against PDAC. PARP7, a mono-ADP-ribosyltransferase, is a negative regulator of the type I interferon (IFN-I) pathway and has been reported to reduce anti-tumour immunity.

Enhancing equity in academic surgery promotion practices.

Background: Black, Indigenous, People of Color (BIPOC) in medicine and women faculty have lower 10-year promotion rates than their White and male peers, despite controlling for productivity metrics. Promotion standards vary across institutions, but there is likely a common need to improve transparency and consistency while mitigating bias, inequity, and the harm of additional equity work that is commonly expected of Black, Indigenous, People of Color and women faculty (the so-called minority tax).

Methods: A promotion advisory committee consisting of clinical and research faculty at all ranks specified expectations for a faculty member at the associate or full professor ranks, with 10-15 examples given for each "mission" (clinical, research, and education).

Translation of dynamic contrast-enhanced imaging onto a magnetic resonance-guided linear accelerator in patients with head and neck cancer.

Background And Purpose: Magnetic resonance imaging - linear accelerator (MRI-linac) systems permit imaging of tumours to guide treatment. Dynamic contrast enhanced (DCE)-MRI allows investigation of tumour perfusion. We assessed the feasibility of performing DCE-MRI on a 1.

β-alanine supplementation in adults with overweight and obesity: a randomized controlled feasibility trial.

Objective: Overweight and obesity are characterized by excess adiposity and systemic, chronic, low-grade inflammation, which is associated with several metabolic disorders. The aim of this study was to assess the feasibility and tolerability of β-alanine supplementation and to explore the effects on cardiometabolic health and cardiovascular, hepatic, and renal function in adults with overweight and obesity.

Methods: A total of 27 adults (44% female; mean [SD], age: 58 [10] years, BMI: 31.
