Article Synopsis
  • Knowledge-based nitrogen (N) management helps align crop nitrogen demand with supply, improving crop yield while minimizing nitrogen losses.
  • Analysis of 5,448 observations from various studies revealed that organic and balanced fertilization increases soil nitrate retention but also leads to more nitrogen leaching and emissions compared to no fertilizer.
  • The use of nitrification inhibitors effectively retains soil ammonium and enhances plant nitrogen uptake, suggesting that combining these management practices is essential for improving nitrogen retention and reducing losses on a global scale.

Li-rich manganese-based cathode materials (LRMs) are considered one of the most promising cathode materials for the next generation of lithium-ion batteries (LIBs) because of their high energy density. However, there are problems such as a capacity decay, poor rate performance, and continuous voltage drop, which seriously limit their large-scale commercial applications. In this work, LiMnCoNiO coated with LiMoO with a unique spinel structure was prepared with the wet chemistry method and the subsequent calcination process.

The internal soil nitrogen (N) cycle supplies N to plants and microorganisms but may induce N pollution in the environment. Understanding the variability of gross N cycling rates resulting from the global spatial heterogeneity of climatic and edaphic variables is essential for estimating the potential risk of N loss. Here we compiled 4,032 observations from 398 published N pool dilution and tracing studies to analyse the interactions between soil internal potential N cycling and environmental effects.

Consistent annotation transfer from reference dataset to query dataset is fundamental to the development and reproducibility of single-cell research. Compared with traditional annotation methods, deep learning based methods are faster and more automated. A series of useful single cell analysis tools based on autoencoder architecture have been developed but these struggle to strike a balance between depth and interpretability.

Microbial nitrogen (N) immobilization, which typically results in soil N retention but based on the balance of gross N immobilization over gross N production, affects the fate of the anthropogenic reactive N. However, global patterns and drivers of soil gross immobilization of ammonium (I ) and nitrate (I ) are still only tentatively known. Here, we provide a comprehensive analysis considering gross N production rates, soil properties, and climate and their interactions for a deeper understanding of the patterns and drivers of I and I .

Dissimilatory nitrate reduction to ammonium (DNRA), the nearly forgotten process in the terrestrial nitrogen (N) cycle, can conserve N by converting the mobile nitrate into non-mobile ammonium avoiding nitrate losses via denitrification, leaching, and runoff. However, global patterns and controlling factors of soil DNRA are still only rudimentarily known. By a meta-analysis of 231 observations from 85 published studies across terrestrial ecosystems, we find a global mean DNRA rate of 0.

Both soil microbial nitrate (NO-N) immobilization and denitrification are carbon (C)-limited; however, to what extent organic C addition may increase NO-N immobilization while stimulate denitrification nitrogen (N) loss remains unclear. Here, N tracing coupled with acetylene inhibition methods were used to assess the effect of adding glucose, wheat straw and peanut straw on NO-N immobilization and denitrification under aerobic conditions in an upland soil, in which NO-N immobilization has been previously demonstrated to be negligible. The organic C sources (5 g C kg soil) were added in a factorial experiment with 100, 500, and 1000 mg N kg soil (as KNO) in a 12-d laboratory incubation.

Purpose: Next-generation sequencing (NGS)-based profiling of both urinary tumor DNA (utDNA) and circulating tumor DNA (ctDNA) shows promise for noninvasive detection and surveillance of urothelial bladder cancer (UBC). However, the analytical performance of these assays remains undefined in the real-world setting. Here, we sought to evaluate the concordance between tumor DNA (tDNA) profiling and utDNA or ctDNA assays using a UBC patient cohort from the intended-use population.

Although crop residue return increases upland soil emissions of nitrous oxide (NO), a potent greenhouse gas, the mechanisms responsible for the increase remain unclear. Here, we investigate NO emission pathways, gross nitrogen (N)-cycling rates, and associated N-cycling gene abundances in an upland soil following the addition of various organic material under aerobic incubation using a combination of N tracing technique, acetylene (CH) inhibition, and real-time PCR (qPCR) methods. Increased total NO emissions following organic material amendment was attributed to both increased nitrification-derived NO emissions, following increased ammonia-oxidizing bacteria (AOB)-amoA abundance, and denitrification-derived NO emissions, following increased nirS and decreased nosZ abundance.

Maintenance of stem-cell identity requires proper regulation of enhancer activity. Both transcription factors OCT4/SOX2/NANOG and histone methyltransferase complexes MLL/SET1 were shown to regulate enhancer activity, but how they are regulated in embryonic stem cells (ESCs) remains further studies. Here, we report a transcription factor BACH1, which directly interacts with OCT4/SOX2/NANOG (OSN) and MLL/SET1 methyltransferase complexes and maintains pluripotency in mouse ESCs (mESCs).

Background: The leptin receptor-deficient knockout (db/db) mouse is a well-established model for studying type II diabetes mellitus (T2DM). T2DM is an important risk factor of intervertebral disc degeneration (IVDD). Although the relationship between type I diabetes and IVDD has been reported by many studies, few studies have reported the effects of T2DM on IVDD in db/db mice model.

Motivation: Sequencing-based 3D genome mapping technologies can identify loops formed by interactions between regulatory elements hundreds of kilobases apart. Existing loop-calling tools are mostly restricted to a single data type, with accuracy dependent on a predefined resolution contact matrix or called peaks, and can have prohibitive hardware costs.

Results: Here, we introduce cLoops ('see loops') to address these limitations.

A few families of transposable elements (TEs) have been shown to evolve into -regulatory elements (CREs). Here, to extend these studies to all classes of TEs in the human genome, we identified widespread enhancer-like repeats (ELRs) and find that ELRs reliably mark cell identities, are enriched for lineage-specific master transcription factor binding sites, and are mostly primate-specific. In particular, elements of MIR and L2 TE families whose abundance co-evolved across chordate genomes, are found as ELRs in most human cell types examined.

Background Context: Single-stage surgery is usually applied to improving the symptoms of coexisting cervical and lumbar stenosis. In most cases, patients' willingness, surgery affordability, surgical trauma, surgical complications and patients' tolerance to surgery all limit the application of single-stage surgery. For patients who cannot receive single-stage surgery, we hope that we can find out by weighing up merits and flaws of the two surgical sites in order to make decision of prioritize one of the two surgery, so as to bring more benefits to the patients.
