Background: Advance care planning for those with treatable but not curable cancer is considered good practice because innovations in treatment options make prognostication much more uncertain. Little is known about how such patients approach future planning.
Aim: To elicit the perceptions and understandings of advance care planning by patients with treatable but not curable cancer.
Rationale & Objective: Cognitive impairment is commonly associated with chronic kidney disease (CKD. A number of intervention approaches have the potential to improve cognitive performance in CKD. Our objective was to characterize interventions studied to improve cognitive performance for adults with CKD across all categories of severity, including kidney failure.

Traditionally, bipolarons are known to form at very high doping levels through the combination of two adjacent polarons, a process that is generally accompanied by structural disorder and impaired carrier transport. Here, it is demonstrated that bipolaron formation can occur at both the early stage with low doping levels and the late stage with high doping levels in 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (FTCNQ) dip-doped conjugated polymer films with glycol sidechains.

Despite progress in developing gas sensing materials, many still struggle to meet fundamental requirements such as adequate sensitivity and stability, particularly due to high operational temperatures. To address this limitation, this study evaluates polymer-metal oxide hybrid materials designed for trace gas detection at room temperature.

Carbon-based materials offer a cost-effective and potentially more stable alternative. The vast majority of carbon-electrode PSCs use the negative-intrinsic-positive (n-i-p) or "hole-transport-layer-free" architectures.

However, their use in direct solar water-splitting devices has been limited by their instability in aqueous environment and recombination losses at the interface with catalysts. Here we report anodes containing PM6:D18:L8-BO photoactive layers reaching high solar water oxidation photocurrent density over 25 mA cm at +1.

While generic tools and guidelines exist, which outline components of quality end-of life care, they may not fully address stroke's unpredictable trajectories, complicating care planning.

Thus, this observational, mixed-methods study investigated patients' and physicians' preferences for CLL first-line treatments.
Materials And Methods: An online discrete choice experiment in five countries among 192 patients and 259 physicians in the US, the UK, Germany, France, and Australia examined the importance of outcomes and treatment attributes.
A key challenge in the development of organic mixed ionic-electronic conducting materials (OMIEC) for high performance electrochemical transistors is their stable performance in ambient. When operating in aqueous electrolyte, potential reactions of the electrochemically injected electrons with air and water could hinder their persistence, leading to a reduction in charge transport. Here, the impact of deepening the LUMO energy level of a series of electron-transporting semiconducting polymers is evaluated, and subsequently rendering the most common oxidation processes of electron polarons thermodynamically unfavorable, on organic electrochemical transistors (OECTs) performance.

Although macrophages and dendritic cells are dedicated to migrating and engulfing dying cells and debris, many epithelial and mesenchymal tissue cells can digest nearby apoptotic corpses. How these non-motile, non-professional phagocytes sense and eliminate dying cells while maintaining their normal tissue functions is unclear.

Herein, we study their effects on electronic states and electronic properties. We find that polymer glycolation not only induces more disordered packing, but also results in a higher reorganisation energy due to more localised π-electron density.

In this work, we found that without resolving lineage plasticity, skin stem cells cannot effectively generate each lineage in vitro nor regrow hair and repair wounded epidermis in vivo. A small-molecule screen unearthed retinoic acid as a critical regulator.

Polyaniline (PANI) and two copolymers, poly(aniline---toluidine) (PoTOL-50) and poly(aniline---anisidine) (PoANI-50) were synthesized with equal input ratios (1:1) to enhance PANI as sensing material for the sensing of various heavy metal analytes in aqueous solutions. The polymers were evaluated for both their sensitivity and selectivity toward four heavy metals (Ba, Cd, Cu, and Ni) and two common matrix interferents (Ca and Mg) at 10 and 40 ppm. The effect of pH and ionic strength of the aqueous solutions on the sensitivity and selectivity was also evaluated.

Understanding the formation and (de)localization of polarons is therefore critical for further developing organic semiconductors as a future electronics platform. However, there are very few studies reported in this area.

However, a substantial number of these dying cells are cleared by 'non-professional phagocytes', local epithelial cells that are critical to organismal fitness. How non-professional phagocytes sense and digest nearby apoptotic corpses while still performing their normal tissue functions is unclear.

However, studies examining soil invertebrates in the Arctic are limited and our understanding of the abiotic and biotic drivers of these invertebrate communities remains understudied. We examined differences in soil invertebrate taxa (mites, collembolans, enchytraeids) among several undisturbed upland tundra heath sites in Nunavut Canada and identified the drivers (vegetation and substrate cover, soil nutrients and pH) of the soil invertebrate community across these sites.

The aim of our study was to examine impacts of land management on aboveground and belowground edge effects, measured by changes in plant community, soil properties, and soil microbial communities across agroecosystem edges. We measured plant composition and biomass, soil properties (total carbon, total nitrogen, pH, nitrate, and ammonium), and soil fungal and bacterial community composition across perennial grassland-annual cropland edges.

Here, we present a summary of 2022 cannabis regulations by state to evaluate for the presence of THC:CBD ratios, maximum THC concentration or content within products, specific caps for cannabis possession, and requirements for testing for cannabinoid content and/or contaminants such as pesticides and heavy metals. These results are presented in Map 1 and Table 1 and demonstrate substantial variation among product THC content, purchasing limits, and quality measurements across the country.

The indirect effects of herbicides on habitat quality in boreal ecoregions remain poorly understood. Herbicides are commonly applied on boreal rights-of-way to control vegetation below power lines, where they can indirectly enter the soil ecosystem after leaf abscission. Key soil processes such as litter decomposition and soil nutrient cycling can be influenced by altering litter chemistry and/or impacting decomposer species.
