Article Synopsis
  • Straw degradation is slow in cold environments, but a consortium of bacteria and fungi, named LHWA, was developed to enhance this process.
  • Under 4 °C, this consortium achieved a 55.52% straw weight loss in liquid fermentation after 30 days and 58.36% in solid fermentation after 60 days.
  • Transcriptomic analysis indicated that B. cereus, part of the consortium, enhances cold resistance by modifying cell membrane fluidity and increasing cold stress response proteins.

How to utilize modern technological means to provide both accurate scoring and objective feedback for martial arts movements has become an issue that needs to be addressed in the field of physical education. This study proposes an intelligent scoring method based on machine learning. Firstly, the key features are extracted by the feature alignment technique, which eliminates the influence of athletes' movement speed, rhythm and duration on the scoring, thus reflecting the athletes' skill level more realistically.

Article Synopsis
  • Pumpkin seedlings experience chilling stress, resulting in increased damage indicators like electrical conductivity and malondialdehyde, while showing decreased levels of antioxidants and chlorophyll.
  • A substantial number of genes (5,780) and metabolites (178) were found to change in response to this stress, with key pathways related to plant hormones and phenylpropanoid biosynthesis being affected.
  • This research enhances the understanding of how pumpkins cope with low temperatures, paving the way for future breeding programs aimed at improving their chilling tolerance.

Purpose: Mitochondrial damage may lead to uncontrolled oxidative stress and massive apoptosis, and thus plays a pivotal role in the pathological processes of myocardial ischemia-reperfusion (I/R) injury. However, it is difficult for the drugs such as puerarin (PUE) to reach the mitochondrial lesion due to lack of targeting ability, which seriously affects the expected efficacy of drug therapy for myocardial I/R injury.

Methods: We prepared triphenylphosphonium (TPP) cations and ischemic myocardium-targeting peptide (IMTP) co-modified puerarin-loaded liposomes (PUE@T/I-L), which effectively deliver the drug to mitochondria and improve the effectiveness of PUE in reducing myocardial I/R injury.

Segmenting plant organs is a crucial step in extracting plant phenotypes. Despite the advancements in point-based neural networks, the field of plant point cloud segmentation suffers from a lack of adequate datasets. In this study, we addressed this issue by generating Arabidopsis models using L-system and proposing the surface-weighted sampling method.

The simultaneous application of in situ capping and electro-enhanced biodegradation may be a suitable method for ensuring the feasibility and safety of reusing abandoned coking sites. However, the capping layer type and applied electric field pattern may affect the efficiency of sequestering and removing pollutants. This study investigated changes in electric current, soil moisture content and pH, polycyclic aromatic hydrocarbon (PAH) concentration, bacterial number, and microbial community structure and metabolic function during soil remediation at abandoned coking plant sites under different applied electric field patterns and barrier types.

Acute myocardial infarction, characterized by high morbidity and mortality, has now become a serious health hazard for human beings. Conventional surgical interventions to restore blood flow can rapidly relieve acute myocardial ischemia, but the ensuing myocardial ischemia-reperfusion injury (MI/RI) and subsequent heart failure have become medical challenges that researchers have been trying to overcome. The pathogenesis of MI/RI involves several mechanisms, including overproduction of reactive oxygen species, abnormal mitochondrial function, calcium overload, and other factors that induce cell death and inflammatory responses.

Article Synopsis
  • The study analyzed the effectiveness and safety of using Xingnaojing in combination with naloxone for treating carbon monoxide poisoning by reviewing relevant literature from various databases.
  • Results showed that the experimental group (Xingnaojing + naloxone) had a higher effective recovery rate and shorter recovery times compared to the control group (naloxone alone), with fewer adverse reactions observed.
  • The conclusion indicates that while Xingnaojing combined with naloxone is more effective than naloxone alone, further high-quality research is needed for validation.

Electro-bioremediation is a promising technology for remediating soils contaminated with polycyclic aromatic hydrocarbons (PAHs). However, the resulting electrokinetic effects and electrochemical reactions may inevitably cause changes in soil factors and microorganism, thereby reducing the remediation efficiency. To avoid negative effect of electric field on soil and microbes and maximize microbial degradability, it is necessary to select a suitable electric field.

In situ capping and bioremediation are common technologies for treating contaminated soil at industrial sites. However, these two technologies have some shortcomings for treating soil heavily contaminated with organic matter, such as the limited adsorption in capping layer and the low biodegradation efficiency. This study proposed the method of an improved in situ capping combined with electrokinetic enhanced-bioremediation, and investigated its feasibility for treating heavily polycyclic aromatic hydrocarbons (PAHs) contaminated soil at an abandoned industrial site.

Based on the inhibition of mitochondrial permeability transition pore (mPTP) opening, puerarin (PUE) has a good potential to reduce myocardial ischemia/reperfusion injury (MI/RI). However, the lack of targeting of free PUE makes it difficult to reach the mitochondria. In this paper, we constructed matrix metalloproteinase-targeting peptide (MMP-TP) and triphenylphosphonium (TPP) cation co-modified liposomes loaded with PUE (PUE@T/M-L) for mitochondria-targeted drug delivery.

Introduction: The flower buds of Thunb. are widely used in Chinese medicine for their anti-inflammatory properties, and they have played an important role in the fight against SARS COVID-19 and other major epidemics. However, due to the lack of scientific and accurate variety identification methods and national unified standards, scattered and non-standardized management in flower bud production has led to mixed varieties that have caused significant difficulties in the cataloging and preservation of germplasm resources and the identification, promotion, and application of new varieties.

Article Synopsis
  • - The study investigates the molecular mechanisms of heterosis in rice by analyzing 418 hybrids created from two testers and 265 rice varieties, revealing that the effectiveness of heterosis is influenced by genetic backgrounds and environmental conditions.
  • - Findings indicate that nonadditive quantitative trait loci (QTLs) are the primary genetic factors contributing to heterosis, showing greater sensitivity to genetic backgrounds than additive QTLs.
  • - The researchers propose a new model called homo-insufficiency under insufficient background (HoIIB), suggesting that heterosis arises not from the advantages of heterozygotes but from disadvantages of homozygotes in poor genetic contexts, offering insights for future hybrid rice breeding strategies.

Background: Accurate segmentation of unruptured cerebral aneurysms (UCAs) is essential to treatment planning and rupture risk assessment. Currently, three-dimensional time-of-flight magnetic resonance angiography (3D TOF-MRA) has been the most commonly used method for screening aneurysms due to its noninvasiveness. The methods based on deep learning technologies can assist radiologists in achieving accurate and reliable analysis of the size and shape of aneurysms, which may be helpful in rupture risk prediction models.

Heavy metal pollution of agricultural soils in sewage irrigation areas is a serious environmental issue. Many prior studies have demonstrated that soil around the irrigation area is polluted with heavy metals, even though they had not been irrigated by wastewater. In this study, a paddy field downstream of the Zhangshi Irrigation Area was selected as the study area.
