The concept of implicative pseudo valuations on hoops is introduced and some related properties are investigated. As an application of properties of pseudo valuations, we find the relationship between a pseudo valuation and an implicative pseudo valuation and obtain some characterizations of implicative pseudo valuations. In particular, we show that a pseudo valuation on regular hoops is implicative if and only if it satisfies φ(x■x') = 0.This result will provide a more general algebraic foundation for pseudo valuations theory on algebraic structures based on substructure logic. 展开更多

Parkinson's disease is a neurodegenerative disorder marked by the degeneration of dopaminergic neurons and clinical symptoms such as tremors,rigidity,and slowed movements.A key feature of Parkinson's disease is the accumulation of misfoldedα-synuclein,forming insoluble Lewy bodies in the substantia nigra pars compacta,which contributes to neurodegeneration.Theseα-synuclein aggregates may act as autoantigens,leading to T-cell-mediated neuroinflammation and contributing to dopaminergic cell death.Our perspective explores the hypothesis that Parkinson's disease may have an autoimmune component,highlighting research that connects peripheral immune responses with neurodegeneration.T cells derived from Parkinson's disease patients appear to have the potential to initiate an autoimmune response againstα-synuclein and its modified peptides,possibly leading to the formation of neo-epitopes.Recent evidence associates Parkinson's disease with abnormal immune responses,as indicated by increased levels of immune cells,such as CD4^(+)and CD8^(+)T cells,observed in both patients and mouse models.The convergence of T cells filtration increasing major histocompatibility complex molecules,and the susceptibility of dopaminergic neurons supports the hypothesis that Parkinson's disease may exhibit autoimmune characteristics.Understanding the immune mechanisms involved in Parkinson's disease will be crucial for developing therapeutic strategies that target the autoimmune aspects of the disease.Novel approaches,including precision medicine based on major histocompatibility complex/human leukocyte antigen typing and early biomarker identification,could pave the way for immune-based treatments aimed at slowing or halting disease progression.This perspective explores the relationship between autoimmunity and Parkinson's disease,suggesting that further research could deepen understanding and offer new therapeutic avenues.In this paper,it is organized to provide a comprehensive perspective on the autoimmune aspects of Parkinson's disease.It investigates critical areas such as the autoimmune response observed in Parkinson's disease patients and the role of autoimmune mechanisms targetingα-synuclein in Parkinson's disease.The paper also examines the impact of CD4~+T cells,specifically Th1 and Th17,on neurons through in vitro and ex vivo studies.Additionally,it explores howα-synuclein influences glia-induced neuroinflammation in Parkinson's disease.The discussion extends to the clinical implications and therapeutic landscape,offering insights into potential treatments.Consequently,we aim to provide a comprehensive perspective on the autoimmune aspects of Parkinson's disease,incorporating both supportive and opposing views on its classification as an autoimmune disorder and exploring implications for clinical applications. 展开更多

Depression is a widespread and debilitating mental health disorder affecting millions globally.Chronotype has been increasingly recognized as a significant factor associated with depression.This review aims to comprehensively dissect the role of chronotype in depression,providing insights into the underlying mechanisms linking chronotype to depression,as well as the potential therapeutic implications.Converging evidence indicates that evening chronotype is notably associated with an elevated risk of depression,more severe symptoms,and a higher rate of suicidality,while morning chronotype may exert a protective effect.These findings highlight that chronotype plays a crucial role in the development,manifestation,and management of depression.Nevertheless,some methodological issues of the existing studies(e.g.,reliance on self-reported chronotype assessments)should be noted and discussed.Further investigations are warranted to elucidate the intricate mechanisms underlying the relationship between chronotype and depression,establish causal links,and optimize the clinical application of chronotype-based interventions for depression. 展开更多

The conversion of subtropical red soils into farmland involves complex transformations of iron oxides.Investigating iron mineralogy can enhance understanding of magnetic minerals in relation to soil formation on farmland in subtropical regions.In this study,we investigated the properties of iron oxide and its environmental implications in the farmland of Meizhou city,Guangdong province.The results showed that farmland soils had higher magnetism than the red soils developed from the same metamorphic rock.The red soils displayed significantly higher concentrations of goethite and hematite than the farmland soils.The dominant factor influencing the magnetic changes in farmland and red soils was the concentration of fine-grained ferromagnetic minerals.Red soil magnetism is an indicator of soil weathering intensity,whereas farmland soil magnetism is closely related to human cultivation activities.In contrast to the red soils,the farmland soils lacked the pronounced transformation of ferromagnetic minerals into hematite and goethite.A vigorous oxidation process catalyzes the transformation of strong magnetic minerals into significant amounts of hematite and goethite,which promotes the reduced magnetism of red soils.The conversion of red soils into farmland soils initially increased the accumulation of ferromagnetic materials due to cultivation processes.However,long-term cultivation led to the gradual loss of fine-grained ferromagnetic minerals,while goethite and lepidocrocite became the dominant magnetic mineral types. 展开更多

BACKGROUND Lumbar disc extrusion,a common spinal disorder,is particularly uncommon in its severely displaced form,especially in young patients.This condition can pose diagnostic challenges due to its nonspecific presentation.CASE SUMMARY A 36-year-old male patient presented with persistent low back pain and radiating leg pain lasting half a month,which had worsened over the previous four days.Lumbar magnetic resonance imaging scans showed an abnormal signal within the vertebral canal at the L3 level,suggesting either a disc cyst or an epidural hematoma.Based on these findings,the patient was provisionally diagnosed with either condition.Surgical exploration was conducted,revealing an extruded lumbar disc,which was subsequently excised.Following surgery,the patient's symptoms completely resolved.CONCLUSION High-grade lumbar disc extrusion in young patients is rare but should be considered in sedentary,physically inactive individuals presenting with lumbocrural pain and abnormal magnetic resonance imaging findings.Early and accurate diagnosis is crucial to avoid misdiagnosis,and prompt open surgery may be necessary in severe cases to alleviate symptoms.The case highlights the impotance of a thorough diagnostic workup and timely surgical intervention in managing such rare but potentially severe spinal disorders. 展开更多
