Research on accelerating the recycling efficiency of waste batteries for new energy vehicles based on a stochastic evolutionary game model.

Although the rapid development of new energy vehicles (NEV) has contributed greatly to China's carbon emission reduction, it has also brought about a problem that needs to be solved, namely the effective recycling of waste batteries. Existing recycling of waste batteries is plagued by a series of problems such as a single recycling channel, inconsistent recycling standards, lack of recycling technology, rampant irregular recycling enterprises, and low consumer participation. Meanwhile, due to the immaturity of the recycling market, the lack of clarity of existing regulations, and the lack of supervision and management, the above problems are becoming more and more serious.

Palmitoylation-dependent regulation of GPX4 suppresses ferroptosis.

S-palmitoylation is a reversible and widespread post-translational modification, but its role in the regulation of ferroptosis has been poorly understood. Here, we elucidate that GPX4, an essential regulator of ferroptosis, is reversibly palmitoylated on cysteine 66. The acyltransferase ZDHHC20 palmitoylates GPX4 and increases its protein stability.

Efficient recognition of Parkinson's disease mice on stepping characters with CNN.

Parkinson's disease (PD), as the second most prevalent neurodegenerative disorder worldwide, impacts the quality of life for over 12 million patients.

Increasing certainty in projected local extreme precipitation change.

The latest climate models project widely varying magnitudes of future extreme precipitation changes, thus impeding effective adaptation planning. Many observational constraints have been proposed to reduce the uncertainty of these projections at global to sub-continental scales, but adaptation generally requires detailed, local scale information. Here, we present a temperature-based adaptative emergent constraint strategy combined with data aggregation that reduces the error variance of projected end-of-century changes in annual extremes of daily precipitation under a high emissions scenario by >20% across most areas of the world.

S1PR3-driven positive feedback loop sustains STAT3 activation and keratinocyte hyperproliferation in psoriasis.

Psoriasis is a chronic inflammatory skin disorder characterized by hyperproliferation of keratinocytes and persistent inflammation. Although persistent activation of signal transducer and activator of transcription 3 (STAT3) is implicated in its pathogenesis, the mechanisms underlying the sustained STAT3 activation remain poorly understood. Here, we identify sphingosine-1-phosphate receptor 3 (S1PR3) as a critical regulator of STAT3 activation and psoriasis pathogenesis, orchestrating a self-amplifying circuit that sustains keratinocyte hyperproliferation and chronic inflammation.

Quaternized and boronic acid dual-functional CoAg nanozymes for label-free, stable, sensitive, and rapid quantitation detection of the bacterial total concentration.

Background: Foodborne pathogenic bacteria lead to a significant increase in illnesses and fatalities annually. In the early stage of a pathogenic bacterial infection, the concentration of bacteria in food is lower than the detection limit of most technology which enhances the difficulty in diagnosis. It is a serious challenge for researchers to develop a rapid, sensitive, accurate, and stable pathogenic bacterial determination method without costly equipment and highly skilled operators.

Rapid screening of pottery lipid residue profile via comprehensive two-dimensional gas chromatography.

Background: Pottery lipid residue analysis has been extensively practiced worldwide as an important part of archaeometry studies, but in some cases, the complexity of archaeological residue cannot be fully revealed by one-dimensional gas chromatography (1D GC) separation. Although the development of comprehensive two-dimensional gas chromatography (GCxGC) has offered another way to achieve better separation and higher resolution, GCxGC separation has rarely been applied to pottery residue analysis. Clearly, GCxGC separation needs to be explored to examine and scrutinize the complexity of pottery lipid residue profile as well as rapid data treatment workflow.

Cotargeting of thioredoxin 1 and glutamate-cysteine ligase in both imatinib-sensitive and imatinib-resistant CML cells.

Chronic myeloid leukemia (CML) is a type of malignancy characterized by harboring the oncogene Bcr-Abl, which encodes the constitutively activated tyrosine kinase BCR-ABL. Although tyrosine kinase inhibitors targeting BCR-ABL have revolutionized CML therapy, native and acquired drug resistance commonly remains a great challenge. Thioredoxin 1 (Trx1) and glutamate-cysteine ligase (GCL), which are two major antioxidants that maintain cellular redox homeostasis, are potential targets for cancer therapy and overcoming drug resistance.

UV responded polyvinyl alcohol bio-active films containing oregano essential oil microcapsules by chitosan-incorporated TiO: Physical properties, release characterizations, bio-functional performances and applications.

In the present study, with oregano essential oil (OEO) as the active ingredient and polyvinyl alcohol/citric acid (PVA/CA) as the composite matrix, ultraviolet (UV) responded PVA bio-active films incorporated with microcapsules, which were established by chitosan-incorporated titanium dioxide (TiO), were constructed. The UV light-triggered process changed the structure of films, including the degradation of PVA, the fracture of ester bonds and the breaking of glycosidic bonds. UV irradiation reduced the elongation at break, increased the light resistance ability, the surface hydrophobicity and the roughness, and accelerated the release of OEO in films.

PEGylation of Dipeptide Linker Improves Therapeutic Index and Pharmacokinetics of Antibody-Drug Conjugates.

Hydrophobic payloads incorporated into antibody-drug conjugates (ADCs) typically are superior to hydrophilic ones in tumor penetration and "bystander killing" upon release from ADCs. However, they are prone to aggregation and accelerated plasma clearance, which lead to reduced efficacies and increased toxicities of ADC molecules. Shielding the hydrophobicity of payloads by incorporating polyethylene glycol (PEG) elements or sugar groups into the ADC linkers has emerged as a viable alternative to directly adopting hydrophilic payloads.

Mechanistic Insights into the Effects of Aged Polystyrene Nanoplastics on the Toxicity of Cadmium to Triticum Aestivum.

The widespread concern over nanoplastics (NPs) has prompted extensive research into their environmental impact. Concurrently, the study examined the combined toxicity of PS NPs and cadmium (Cd) on wheat. As indicated by the results of in situ Micro-ATR/FTIR, the aging process of PS NPs (50 nm) led to an increase in carbonyl and hydroxyl groups on their surface, enhancing hydrophilicity and consequently, the adsorption capacity for Cd.

Development of Off-On Near-Infrared Fluorescent Probes for Sensitive In Vivo Imaging of Amyloid-β Species with Enhanced Pharmacokinetic.

The fluorescent imaging of pathologically accumulated β-amyloid (Aβ) proteins is of significant importance to the diagnosis of Alzheimer's disease (AD). In the paper, we prepared two new NIR probes, NIR-1 and NIR-2, through hydrophilic modification of introducing water-soluble bioactive groups such as polyethylene glycol (PEG) and morpholine to tune in vivo pharmacokinetics for specific detection of soluble and insoluble Aβ species. The in vitro assessments confirm that both NIR-1 and NIR-2 display strong near-infrared (NIR) fluorescence (FL) enhancement upon association with Aβ42 monomers, oligomers or aggregates (λem > 670 nm) and show high sensitive, rapid and selective response towards Aβ42 species.
