The comparison of outcomes in liver transplantation (LT) is hampered by using clinically nonrelevant surrogate endpoints and considerable variability in reported relevant posttransplant outcomes. Such variability stems from nonstandard outcome measures across studies, variable definitions of the same complication, and different timing of reporting. The Clavien-Dindo classification was established to improve the rigor of outcome reporting but is nonspecific to an intervention, and there are unsolved dilemmas specifically related to LT.

Background: The skin fungal communities of animals play a crucial role in maintaining host health and defending against pathogens. Because fungal infections can affect the skin microbiota of bats, gaining a comprehensive understanding of the characteristics of healthy bat skin fungal communities and the ecological processes driving them provides valuable insights into the interactions between pathogens and fungi.

Methods: We used Kruskal-Wallis tests and Permutational Multivariate Analysis of Variance (PERMANOVA) to clarify differences in skin fungal community structure among bat species.

Hydrogen peroxide (HO) is a crucial chemical applied in various industry sectors. However, the current industrial anthraquinone process for HO synthesis is carbon-intensive. With sunlight and renewable electricity as energy inputs, photocatalysis and electrocatalysis have great potential for green HO production from oxygen (O) and water (HO).

Conventional diffusion-weighted imaging (DWI) sequences employing a spin echo or stimulated echo sensitize diffusion with a specific b-value at a fixed diffusion direction and diffusion time (Δ). To compute apparent diffusion coefficient (ADC) and other diffusion parameters, the sequence needs to be repeated multiple times by varying the b-value and/or gradient direction. In this study, we developed a single-shot multi-b-value (SSMb) diffusion MRI technique, which combines a spin echo and a train of stimulated echoes produced with variable flip angles.

Nitrous acid (HONO) serves as a substantial contributor in the atmospheric chemistry of hydroxyl radicals (·OH). Despite its significance, the primary sources of atmospheric HONO, particularly diesel truck emissions, have not been thoroughly examined. This study investigated the factors influencing HONO emissions via on-road exhaust emission tests using a self-developed portable measurement system.

Article Synopsis
  • A study aimed to explore the prevalence of penile fractures (PF) in men with Ehlers-Danlos Syndrome (EDS) and Marfan Syndrome (MFS), revealing that these patients have significantly higher rates of PF compared to disease-free controls.
  • The research analyzed a large database over 30 years, finding that men with EDS had a prevalence ratio of 30.18 and those with MFS had a ratio of 23.4 for PF.
  • While the study highlights an important link between connective tissue diseases and sexual health issues, it is limited by its reliance on claims data, which lacks finer details on disease progression and complications.

Current therapies against pancreatic ductal adenocarcinoma (PDAC) have limited clinical benefits owing to tumor heterogeneity and their unique immunosuppressive microenvironments. The eukaryotic initiation factor (eIF) 4F complex is involved in regulating translation and various downstream carcinogenic signaling pathways. We report that eIF4G1, one of the subunits of eIF4F, is overexpressed in cancer cells and cancer-associated fibroblasts, and this correlates with poor prognosis in patients with PDAC.

Enamel protects teeth from external irritation and its formation involves sequential differentiation of ameloblasts, a dental epithelial cell. Keratinocyte differentiation factor 1 (KDF1) is important in the development of epithelial tissues and organs. However, the specific role of KDF1 in enamel formation and corresponding regulatory mechanisms are unclear.

Article Synopsis
  • NaMnZr(PO) has been a key material in sodium-ion battery research, known for its abundant manganese and high operating voltage, but faces challenges like poor conductivity and cycling performance due to the Jahn-Teller effect.
  • A new ternary material, NaMnTiZr(PO)/C, is introduced that substitutes Ti for Zr, which lessens the Jahn-Teller effect and strengthens the crystal structure, improving stability.
  • Tests show that this Ti substitution significantly enhances electronic conductivity and sodium ion diffusion, leading to better electrochemical performance, achieving a discharge capacity of 71.0 mAh/g and retaining 78.8% capacity after 1000 cycles.

In Houston, Texas, nitrogen dioxide (NO) air pollution disproportionately affects Black, Latinx, and Asian communities, and high ozone (O) days are frequent. There is limited knowledge of how NO inequalities vary in urban air quality contexts, in part from the lack of time-varying neighborhood-level NO measurements. First, we demonstrate that daily TROPOspheric Monitoring Instrument (TROPOMI) NO tropospheric vertical column densities (TVCDs) resolve a major portion of census tract-scale NO inequalities in Houston, comparing NO inequalities based on TROPOMI TVCDs and spatiotemporally coincident airborne remote sensing (250 m × 560 m) from the NASA TRacking Aerosol Convection ExpeRiment-Air Quality (TRACER-AQ).

Background: Begomoviruses are major constraint in the production of many crops. Upon infection, begomoviruses may substantially modulate plant biological processes. While how monopartite begomoviruses interact with their plant hosts has been investigated extensively, bipartite begomoviruses-plant interactions are understudied.

Introduction: Fetal membrane inflammation is an integral event of parturition. However, excessive pro-inflammatory cytokines can impose threats to the fetus. Coincidentally, the fetal membranes express abundant 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1), which generates biologically active cortisol to promote labor through induction of prostaglandin synthesis.

Seawater electrolysis can generate carbon-neutral hydrogen but its efficiency is hindered by the low mass activity and poor stability of commercial catalysts at industrial current densities. Herein, Pt nanoclusters are loaded on nickel-iron-cobalt phosphide nanosheets, with the obtained Pt@NiFeCo-P electrocatalyst exhibiting excellent hydrogen evolution reaction (HER) activity and stability in alkaline seawater at ampere-level current densities. The catalyst delivers an ultralow HER overpotential of 19.

Article Synopsis
  • The quality of organic thin films impacts carrier dynamics in organic semiconductors, where small voids allow moisture to create charge traps that reduce carrier mobility.
  • While much research has focused on non-doped films, there is insufficient understanding of these traps in doped films, signaling a need for improved molecular design strategies.
  • The proposed molecular design introduces "nano-cluster" structures in doped films that enhance performance by reducing defects and improving carrier injection, leading to significantly higher efficiency in TADF-OLED devices.

Organic-inorganic lead halide perovskites (OLHPs) have demonstrated exceptional properties in high-performance photoelectric devices. However, the impact of A-site cations, specifically formamidinium and methylammonium (MA), on the optoelectronic properties of OLHPs, particularly in the context of hot carrier utilization, remains a topic of debate. In this study, we propose a method for characterizing hot carrier transportation by measuring the hot carrier mobility and momentum-dependent transient photocurrent influenced by A-site cations in OLHPs.

Root-associated microbiota profoundly affect crop health and productivity. Plants can selectively recruit beneficial microbes from the soil and actively balance microbe-triggered plant-growth promotion and stress tolerance enhancement. The cost associated with this is the root-mediated support of a certain number of specific microbes under nutrient limitation.
