The DNA repair enzyme O6-Methylguanine DNA Methyltransferase (MGMT) is a major contributor in conferring resistance to alkylating agents such as temozolomide (TMZ) in cancers. The use of MGMT inhibitors can suppress resistance and enhance the efficacy of TMZ. However, current inhibitors are nonselective for cancer cells, and as a result, MGMT is also inhi ...

Speech takes place in physical environments with visual and acoustic properties, yet how these elements and their interaction influence speech production is not fully understood. While a room's appearance can suggest its acoustics, it is unclear whether people adjust their speech based on this visual information. Previous research shows that higher re ...

Redox noninnocent ligands present opportunities to access reactive metal-radical complexes, but competing redox pathways often hinder their selective formation. Here, a pentadentate arylhydroxylamine-containing (ArNHOH) ligand directs copper salts to form a single, well-defined CuII-arylnitrosyl ...

The 2023 wildfires caused serious riks to air quality and public health across various provinces in Canada, particularly during the period from May to June. This study aims to systematically evaluate the impact of the May-June wildfire events on air pollution in Canada using satellite Aerosol Optical Depth (AOD) data, along with the Hybrid Single-Particle ...

Crucial in disease analysis and surgical planning, manual segmentation of volumetric medical scans (e.g. MRI, CT) is laborious, error-prone, and challenging to master, while fully automatic algorithms can benefit from user feedback. Therefore, with the complementary power of the latest radiological AI foundation models and virtual reality (VR)'s intui ...

Abstinence from drug use is often the result of the associated negative consequences. However, relapse occurs in a large proportion of abstinent users, and the underlying brain mechanisms are not clear. An arguably relevant brain area is the posterior paraventricular nucleus of the thalamus (pPVT ...

Mutations in the TANGO2 gene are associated with a severe neurometabolic disorder in humans, often presenting with life-threatening metabolic crisis. However, the function of TANGO2 protein remains unknown. It has recently been proposed that TANGO2 transports heme within and between cells, from a ...

Iron hydroxides play a key role in the preservation of organic matter in soils and sediments, yet the specificity and extent of their interactions with lignin-derived phenols-important source indicators for terrestrial organic matter-remain poorly understood in aquatic systems. In this study, we analyzed surface and downcore sediments along the terrestria ...
