Background: Non-Hodgkin lymphoma (NHL) is the seventh most common cancer among Asian, Native Hawaiian and Pacific Islanders (ANHPIs), yet the risk of death in specific ANHPI subgroups in the US is unknown.

Methods: We used Surveillance, Epidemiology, and End Results data to investigate relative survival and the risk of death among NHL patients in ANHPI subgroups. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals (CI), comparing ANHPI subgroups to non-Hispanic White (NHW) NHL patients for all-cause death and NHL-specific death.

The contribution of cognitive disengagement syndrome symptoms to depressive symptoms among pediatric brain tumor survivors.

Objective: Pediatric brain tumor survivors (PBTS) are at risk for neurocognitive late effects that can resemble symptoms of cognitive disengagement syndrome (CDS). In the current study, we compared the CDS symptoms of PBTS to those of healthy comparison classmates (CC) and examined whether CDS might explain group differences in depressive symptoms. We also explored whether CDS symptoms were associated with engagement-based coping strategies and stress responses, thereby testing one mechanism by which CDS could lead to affective difficulties.

What Kills Mature Street and Park Trees in Cities? Systematic Quantitative Review of Published Case Studies.

Street and park trees often endure harsher conditions, including increased temperatures and drier soil and air, than those found in urban or natural forests. These conditions can lead to shorter lifespans and a greater vulnerability to dieback. This literature review aimed to identify confirmed causes of street and park tree dieback in urban areas from around the world.

Operando Characterization of Fe in Doped Ni(Fe)OH Catalysts for Electrochemical Oxygen Evolution.

Iron-doped nickel oxyhydroxides, Ni(Fe)OH, are among the most promising oxygen evolution reaction (OER) electrocatalysts in alkaline environments. Although iron (Fe) significantly enhances the catalytic activity, there is still no clear consensus on whether Fe directly participates in the reaction or merely acts as a promoter. To elucidate the Fe's role, we performed X-ray spectroscopy studies supported by DFT on Ni(Fe)OH electrocatalysts.

Combining Brillouin Light Scattering Spectroscopy and Machine-Learned Interatomic Potentials to Probe Mechanical Properties of Metal-Organic Frameworks.

The mechanical properties of metal-organic frameworks (MOFs) are of high fundamental and practical relevance. A particularly intriguing technique for determining anisotropic elastic tensors is Brillouin scattering, which so far has rarely been used for highly complex materials like MOFs. In the present contribution, we apply this technique to study a newly synthesized MOF-type material, referred to as GUT2.

Lipid membranes form the primary structure of cell membranes and serve as configurable interfaces across numerous applications including biosensing technologies, antifungal treatments, and therapeutic platforms. Therefore, the modification of lipid membranes by additives has important consequences in both biological processes and practical applications. In this study, we investigated a nicotinic-acid-based gemini surfactant (NAGS) as a chemically tunable molecular additive for modulating the structure and phase behavior of liposomal membranes.

Coarse-Graining Chemical Networks by Trimming to Preserve Energy Dissipation.

Continuous production of entropy and the corresponding energy dissipation is a defining characteristic of nonequilibrium systems. When a system's full chemical kinetic description is known, its entropy production rate can be computed from the microscopic rate constants. However, such a calculation typically underestimates energy dissipation when the states of the underlying system are mesoscopic, i.

EPR Characterization of the BlsE Substrate Radical Offers Insight into the Determinants of Reaction Outcome that Distinguish Radical SAM Dioldehydratases from Dehydrogenases.

A small but growing set of radical SAM (-adenosyl-l-methionine) enzymes catalyze the radical mediated dehydration or dehydrogenation of 1,2-diol substrates. In some cases, these activities can be interchanged via minor structural perturbations to the reacting components raising questions regarding the relative importance of hyperconjugation, proton circulation and leaving group stability in determining the reaction outcome. The present work describes trapping and electron paramagnetic resonance (EPR) characterization of an α-hydroxyalkyl radical intermediate during dehydration and dehydrogenation of cytosylglucuronic acid and its derivatives catalyzed by the radical SAM enzyme BlsE and its Glu189Ala mutant from the blasticidin S biosynthetic pathway.

A Noncatalytic Cysteine Residue Modulates Cobalamin Reactivity in the Human B Processing Enzyme CblC.

Human CblC catalyzes the indispensable processing of dietary vitamin B by the removal of its β-axial ligand and an either one- or two-electron reduction of its cobalt center to yield cob(II)alamin and cob(I)alamin, respectively. Human CblC possesses five cysteine residues of an unknown function. We hypothesized that Cys149, conserved in mammals, tunes the CblC reactivity.
