Ecological restoration reduces greenhouse gas emissions by altering planktonic and sedimentary microbial communities in a shallow eutrophic lake.

Ecological restoration is a promising approach to alleviate eutrophication. However, its impacts on greenhouse gas (GHG) emissions and the underlying microbial mechanisms in different habitats of lakes remain unclear. To address this knowledge gap, we measured carbon dioxide (CO), methane (CH) and nitrous oxide (NO) fluxes at both water-air and sediment-water interfaces of eutrophic (Caohai) and restored area (Dapokou) of Dianchi Lake, a typical eutrophic lake in China.

Indirect treatment comparison of oral sebetralstat and intravenous recombinant human C1 esterase inhibitor for on-demand treatment of hereditary angioedema attacks.

Four on-demand treatments have been approved thus far (ecallantide, icatibant, recombinant human C1 esterase inhibitor [rhC1INH], and plasma-derived C1INH). Results from the sebetralstat phase 3 KONFIDENT trial (NCT05259917) have been reported.

Causal Relationship Between Intelligence, Noncognitive Education, Cognition and Urinary Tract or Kidney Infection: A Mendelian Randomization Study.

Background: The occurrence of urinary tract or kidney infection is correlated with intelligence, noncognitive education and cognition, but the causal relationship between them remains uncertain, and which risk factors mediate this causal relationship remains unknown.

Methods: The intelligence (n=269,867), noncognitive education (n=510,795) and cognition data (n=257,700) were obtained from genome-wide association studies (GWAS) conducted in individuals of European ethnicities. The genetic associations between these factors and urinary tract or kidney infection (UK Biobank, n=397,867) were analyzed using linkage disequilibrium score regression.

A systematic review and meta-analysis of the effectiveness of remdesivir to treat SARS-CoV-2 infection in hospitalized patients: have the guidelines evolved with the evidence?

Background: With progressive accumulation of knowledge on SARS-CoV-2 infection clinical management, treatment guidelines recommended several options including remdesivir (RDV), a broad-spectrum antiviral. Given the evolving nature of COVID-19, capturing the totality of scientific evidence from clinical trials and observational studies is critical to inform clinical decision making. We conducted a systematic literature review (SLR) with meta-analysis (MA) to summarize RDV effectiveness among hospitalized adults.

Interface-Tailored Secondary Excitation and Ultrafast Charge/Energy Transfer in TiCT-MoS Heterostructure Films.

Charge/energy separation across interfaces of plasmonic materials is vital for minimizing plasmonic losses and enhancing their performance in photochemical and optoelectronic applications. While heterostructures combining plasmonic two-dimensional transition metal carbides/nitrides (MXenes) and semiconducting transition metal dichalcogenides (TMDs) hold significant potential, the mechanisms governing plasmon-induced carrier dynamics at these interfaces remain elusive. Here, we uncover a distinctive secondary excitation phenomenon and an ultrafast charge/energy transfer process in heterostructure films composed of macro-scale TiCT and MoS films.

Rational Construction of Layered Two-Dimensional Conjugated Metal-Organic Frameworks with Room-Temperature Quantum Coherence.

Two-dimensional conjugated metal-organic frameworks (2D c-MOFs) have emerged as an intriguing class of quantum materials due to their high crystallinity, persistent spin centers, and tunable structures and topologies. However, it remains unclear how to achieve long spin relaxation time at room temperature in 2D c-MOFs via a bottom-up design strategy. Herein, we design a hexahydroxytrithiatruxene ligand (HHTH) to minimize the influence of nuclear spin on electron spin relaxation while weakening -π conjugation to construct a "spin docking" for preserving spin centers, which enables the resulting 2D c-MOFs, NiHHTH, to exhibit quantum coherence and Rabi oscillations at room temperature.

Carbon emission effects of land use change in Nanchang, West of Central China Region.

Urban development leads to frequent changes in land use, which leads to temporal and spatial variation of carbon emissions. In this study, land use change data, economic and social data, and energy consumption data of Nanchang City from 2000 to 2020 were used to estimate the spatio-temporal evolution of carbon emissions in Nanchang City, and the LMDI model was used to identify the main driving factors affecting the change of carbon emissions in Nanchang City. It is found that from 2000 to 2020, the carbon emission of Nanchang City has a great change, showing a "parabolic" change law, that is, rising first and then decreasing.

Selenium-Substitution Strategy for Enhanced Mobility, Tunable Bandgap, and Improved Electrochemical Energy Storage in Semiconducting Conjugated Coordination Polymers.

Conjugated coordination polymers (c-CPs), a novel class of organic-inorganic hybrid materials, are distinguished by their unique structural characteristics and exceptional charge transport properties. The electronic properties of these materials are critically determined by the constituting coordination atoms, with electron-rich selenol ligands emerging as promising candidates for constructing high-mobility semiconducting c-CPs. Despite their potential, c-CPs incorporating selenium-substituted ligands remain scarce due to the synthetic challenges associated with both the ligands and the coordination polymers.
