Due to the complex physical properties of low-permeability glutenite reservoirs, the oil recovery rate with conventional development is low. Surfactants are effective additives for enhanced oil recovery (EOR) due to their good ability of wettability alteration and interfacial tension (IFT) reduction, but the reason why imbibition efficiencies vary with different types of surfactants and the mechanism of enhanced imbibition in the glutenite reservoirs is not clear. In this study, the imbibition efficiency and recovery of surfactants including the nonionic, anionic, and cationic surfactants as well as nanofluids were evaluated and compared with produced water (PW) using low-permeability glutenite core samples from the Lower Urho Formation in the Mahu oil field.

Parkinson's disease (PD) is a common neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra and the accumulation of α-synuclein in the brain. Ferroptosis, a recently identified form of regulated cell death, is critical in PD pathogenesis due to its association with iron deposition, overproduction of reactive oxygen species, iron-dependent lipid peroxidation and impaired lipid peroxidation clearance. This cell death mechanism is closely linked to several pathogenic processes in PD, including α-synuclein aggregation, oxidative stress, mitochondrial dysfunction, microglia-induced neuroinflammation, and neuromelanin accumulation.

Microorganisms play dual roles in soil organic carbon (SOC) decomposition and accumulation. Despite advancing insights into their involvement in the carbon cycle, understanding the impact of microbial community structure and physiological traits on SOC stabilization in arid and semi-arid grasslands remains elusive. Here, we analyzed arid and semi-arid grasslands SOC stability by comparing the ratio of mineral-associated organic carbon (MAOC) to particulate organic carbon (POC) across a grassland transect in north-south Ningxia, encompassing various grassland types and a broad climatic gradient (ΔMAP = 450 mm).

False smut caused by is one of the most destructive diseases in rice. The disease is primarily controlled with fungicides, leading to the development of fungicide resistance. Although spray-induced gene silencing (SIGS) has been utilized for disease management, it has not been applied to control rice false smut.

Article Synopsis
  • - The study focuses on lung adenocarcinoma, a severe type of lung cancer, and investigates the role of a protein called MYST2, which is found to be overexpressed in cancerous tissues and linked to worse outcomes.
  • - Researchers used various methods, including database analysis and functional assays, to demonstrate that increasing MYST2 levels promotes cancer cell growth and movement, while reducing MYST2 levels leads to decreased cancer activity.
  • - The findings reveal that MYST2 enhances the activity of key signaling molecules involved in cancer progression, suggesting it could serve as both a prognostic marker and a target for new cancer treatments.

Article Synopsis
  • The study investigates the effectiveness of the traditional Chinese medicine Fuke Qianjin capsule (FKQ) in treating sequelae of pelvic inflammatory disease (SPID), which affects female reproductive organs and surrounding tissue.
  • FKQ shows protective effects against pathogenic bacteria linked to SPID, reduces uterine damage, and minimizes inflammation by inhibiting pro-inflammatory cytokines and balancing immune cell types in a rat model.
  • The research concludes that FKQ operates through a combination of antibacterial, anti-inflammatory, reparative, and immune-enhancing actions to treat SPID effectively.

Background: Radiation-induced skin injury (RISI) represents a significant complication in patients receiving radiotherapy and individuals exposed to nuclear accidents, characterized by a protracted wound-healing process relative to injuries from other etiologies. Current preventive and management approaches remain inadequate. Consequently, investigating efficacious intervention strategies that target the disease's progression characteristics holds significant practical importance.

Cancer treatment has been rapidly transformed by the development of immune checkpoint inhibitors targeting CTLA-4 and PD-1/PD-L1. However, many patients fail to respond, especially those with an immunosuppressive tumor microenvironment (TME), suggesting the existence of additional immune checkpoints that act through orthogonal mechanisms. Sialic acid-binding immunoglobulin-like lectin (Siglec)-7 and -9 are newly designated glycoimmune checkpoints that are abundantly expressed by tumor-infiltrating myeloid cells.

Proteolysis targeting chimeras (PROTACs) represent a transformative class of therapeutic agents that leverage the intrinsic protein degradation machinery to modulate the hemostasis of key disease-associated proteins selectively. Although several PROTACs have been approved for clinical application, suboptimal therapeutic efficacy and potential adverse side effects remain challenging. Benefiting from the enhanced targeted delivery, reduced systemic toxicity, and improved bioavailability, nanomedicines can be tailored with precision to integrate with PROTACs which hold significant potential to facilitate PROTAC nanomedicines (nano-PROTACs) for clinical translation with enhanced efficacy and reduced side effects.

Spatial proteomics is a multidimensional technique that studies the spatial distribution and function of proteins within cells or tissues across both spatial and temporal dimensions. This field multidimensionally reveals the complex structure of the human proteome, including the characteristics of protein spatial distribution, dynamic protein translocation, and protein interaction networks. Recently, as a crucial method for studying protein spatial localization, spatial proteomics has been applied in the clinical investigation of various diseases.

CD4+ T cells are central mediators of protective immunity to blood-stage malaria, particularly for their capacity in orchestrating germinal center reaction and generating parasite-specific high-affinity antibodies. T follicular helper (Tfh) cells are predominant CD4+ effector T cell subset implicated in these processes, yet the factors and detailed mechanisms that assist Tfh cell development and function during Plasmodium infection are largely undefined. Here we provide evidence that receptor for activated C kinase 1 (RACK1), an adaptor protein of various intracellular signals, is not only important for CD4+ T cell expansion as previously implied but also plays a prominent role in Tfh cell differentiation and function during blood-stage Plasmodium yoelii 17XNL infection.

Due to the lack of direct assessment metrics, existing studies on the intensity of agricultural policies often utilize indicators such as Gross Domestic Product (GDP) of agriculture or the quantity of agricultural policies as measures. Optimizing methods for analyzing the intensity of agricultural policies will significantly impact parameter selection in agricultural policy research and the evaluation of policy effectiveness. In this study, we constructed a Chinese Agricultural Policy Corpus using agricultural policies released by various governmental agencies at the national level in China from 1982 to April 2023.
