Peanut oil is more environmentally sustainable than rapeseed oil from a carbon and nitrogen footprint perspective in China.

Peanut and rapeseed oil, prominent edible oils in China, significantly contribute to greenhouse gas and reactive nitrogen emissions. A comprehensive examination of their environmental footprints is foundational for developing green and low-carbon products. Using a cradle-to-factory gate life cycle assessment, we quantified the carbon footprint (CF) and nitrogen footprint (NF) associated with the oil production of peanut and rapeseed from 2004 to 2023 in China.

NRG1 fusion glycoproteins in cancer progression - Structural mechanisms and therapeutic potential: A review.

Neuregulin 1 (NRG1) is a transmembrane glycoprotein ligand of the ErbB receptor family, playing a critical role in macromolecular signaling that regulates cell growth and survival. Chromosomal rearrangements can fuse NRG1 to other genes, creating oncogenic variants that hijack ErbB2/ErbB3 signaling. The resulting chimeric fusion proteins retain the EGF-like domain of NRG1, enabling aberrant dimerization and sustained activation of ErbB2/ErbB3 macromolecular complexes, which in turn activate downstream pathways such as PI3K-AKT and MAPK.

Social Chiral Self-Sorting Synthesis of [9]Cycloparaphenylene-Pillar[5]arene Heterochiral Multicavity Macrocyclic Trimers with Circularly Polarized Luminescence.

The precise synthesis of stereochemically controlled multicavity macrocyclic hosts based on pillar[n]arenes presents a significant challenge in supramolecular chemistry. This difficulty primarily stems from the spontaneous generation of planar chirality-induced stereoisomer mixtures during synthetic procedures, which considerably complicates the isolation process. In this study, we introduce a social chiral self-sorting strategy utilizing a triangular gold complex, enabling the stereochemically controlled synthesis of [9]cycloparaphenylene-pillar[5]arene trimers ([9]CPP-3P[5]A).

An anthracene-containing crown ether: synthesis, host-guest properties and modulation of solid state luminescence.

Organic solid state vapochromic materials are of great significance for the development of supramolecular chemistry and materials science. Herein, we synthesize a crown ether derivative (An34C10) containing two anthracene units and construct new crown ether-based vapochromic host-guest co-crystals. Due to the presence of anthracene, An34C10 not only shows good fluorescence properties but also displays mechanochromism.

Synthesizing LiFePO by phosphate & iron recovered from sludge-incinerated ash and Li extracted from concentrated brines.

Phosphorus (P) recovered from sludge-incinerated ash (SIA) could be applied to synthesize highly added-value products (FePO and LiFePO) with in situ Fe in SIA. Indeed, LiFePO is a future of rechargeable batteries, which makes lithium (Li) highly needed. Alternatively, Li could also be extracted from concentrated brines to face a potential crisis of Li depletion on lands.

Distribution characteristics of sulfonamide antibiotics between water and extracellular polymeric substances in municipal sludge.

The interaction between extracellular polymeric substances (EPS) in municipal sludge and antibiotics in wastewater is critical in wastewater treatment, resource recovery, and sludge management. Therefore, it is increasingly urgent to investigate the distribution coefficient (Log K) of sulfonamide antibiotics (SAs) in EPS, particularly in sludge-derived dissolved organic carbon (DOC) and aqueous phase systems. Herein, through balance experiments, the concentrations of SAs were determined using alkaline extraction EPS (AEPS) and alginate-like extracellular polymer (ALE) systems, and the Log K values were determined.

An Experimental Investigation of the Effects of Block Proportion on Bimrocks, Considering Different Block-to-Matrix Strength Ratios.

The rock block proportion is one of the most important factors affecting the mechanical properties of bimrocks. Under different block-to-matrix strength ratios, the influence of rock block proportion is different. To explore the influence of rock block proportion on the mechanical properties of specimens under different block-to-matrix strength ratios, a new indoor test method for making bimrocks was proposed.

Efficient separation of monobromotoluene isomers by nonporous adaptive perbromoethylated pillar[5]arene crystals.

Herein we report an efficient adsorptive separation approach for monobromotoluene isomers using nonporous adaptive crystals of perbromoethylated pillar[5]arene (BrP5). The purity of separated -bromotoluene from an equal volume mixture of -bromotoluene and -bromotoluene reaches 96.6% in one cycle and the adsorbent BrP5 can be reused without losing separation performance.

Genetic dissection of mutual interference between two consecutive learning tasks in .

Animals can continuously learn different tasks to adapt to changing environments and, therefore, have strategies to effectively cope with inter-task interference, including both proactive interference (Pro-I) and retroactive interference (Retro-I). Many biological mechanisms are known to contribute to learning, memory, and forgetting for a single task, however, mechanisms involved only when learning sequential different tasks are relatively poorly understood. Here, we dissect the respective molecular mechanisms of Pro-I and Retro-I between two consecutive associative learning tasks in .

Mapping white matter structural covariance connectivity for single subject using wavelet transform with T1-weighted anatomical brain MRI.

Introduction: Current studies of structural covariance networks were focused on the gray matter in the human brain. The structural covariance connectivity in the white matter remains largely unexplored. This paper aimed to build novel metrics that can infer white matter structural covariance connectivity, and to explore the predictive power of the proposed features.

Differential conditioning produces merged long-term memory in .

Multiple spaced trials of aversive differential conditioning can produce two independent long-term memories (LTMs) of opposite valence. One is an aversive memory for avoiding the conditioned stimulus (CS+), and the other is a safety memory for approaching the non-conditioned stimulus (CS-). Here, we show that a single trial of aversive differential conditioning yields one merged LTM (mLTM) for avoiding both CS+ and CS-.

Pollution and ecological risk assessment, and source identification of heavy metals in sediment from the Beibu Gulf, South China Sea.

The Beibu Gulf is an important passageway between China and the Association of Southeast Asian Nations, where there has been an increase in pollution of heavy metals (HMs). High concentrations of Pb, Cr, Cd, Cu, Zn, As, and Hg in surface sediment were found in Qinzhou Bay, Fangchenggang, and other coastal areas. Stochastic geo-accumulation analyses identified the pollution to be "uncontaminated"; however, it had an 18% probability of deterioration.

Long-term memory is formed immediately without the need for protein synthesis-dependent consolidation in Drosophila.

It is believed that long-term memory (LTM) cannot be formed immediately because it must go through a protein synthesis-dependent consolidation process. However, the current study uses Drosophila aversive olfactory conditioning to show that such processes are dispensable for context-dependent LTM (cLTM). Single-trial conditioning yields cLTM that is formed immediately in a protein-synthesis independent manner and is sustained over 14 days without decay.

DNA barcoding and the identification of tree frogs (Amphibia: Anura: Rhacophoridae).

The DNA barcoding gene COI (cytochrome c oxidase subunit I) effectively identifies many species. Herein, we barcoded 172 individuals from 37 species belonging to nine genera in Rhacophoridae to test if the gene serves equally well to identify species of tree frogs. Phenetic neighbor joining and phylogenetic Bayesian inference were used to construct phylogenetic trees, which resolved all nine genera as monophyletic taxa except for Rhacophorus, two new matrilines for Liuixalus, and Polypedates leucomystax species complex.
