文摘Alzheimer’s disease is initially thought to be caused by age-associated accumulation of plaques,in recent years,research has increasingly associated Alzheimer’s disease with lysosomal storage and metabolic disorders,and the explanation of its pathogenesis has shifted from amyloid and tau accumulation to oxidative stress and impaired lipid and glucose metabolism aggravated by hypoxic conditions.However,the underlying mechanisms linking those cellular processes and conditions to disease progression have yet to be defined.Here,we applied a disease similarity approach to identify unknown molecular targets of Alzheimer’s disease by using transcriptomic data from congenital diseases known to increase Alzheimer’s disease risk,namely Down syndrome,Niemann-Pick type C disease,and mucopolysaccharidoses I.We uncovered common pathways,hub genes,and miRNAs across in vitro and in vivo models of these diseases as potential molecular targets for neuroprotection and amelioration of Alzheimer’s disease pathology,many of which have never been associated with Alzheimer’s disease.We then investigated common molecular alterations in brain samples from a Niemann-Pick type C disease mouse model by juxtaposing them with brain samples of both human and mouse models of Alzheimer’s disease.Detailed phenotypic,molecular,chronological,and biological aging analyses revealed that the Npc1tm(I1061T)Dso mouse model can serve as a potential short-lived in vivo model for brain aging and Alzheimer’s disease research.This research represents the first comprehensive approach to congenital disease association with neurodegeneration and a new perspective on Alzheimer’s disease research while highlighting shortcomings and lack of correlation in diverse in vitro models.Considering the lack of an Alzheimer’s disease mouse model that recapitulates the physiological hallmarks of brain aging,the short-lived Npc1^(tm(I1061T)Dso) mouse model can further accelerate the research in these fields and offer a unique model for understanding the molecular mechanisms of Alzheimer’s disease from a perspective of accelerated brain aging.

文摘With the efficient and intelligent development of computer-based big data processing,applying machine learning methods to the processing and interpretation of logging data in the field of geophysical well logging has broad potential for improving production efficiency.Currently,the Jiyuan Oilfield in the Ordos Basin relies mainly on manual reprocessing and interpretation of old well logging data to identify different fluid types in low-contrast reservoirs,guiding subsequent production work.This study uses well logging data from the Chang 1 reservoir,partitioning the dataset based on individual wells for model training and testing.A deep learning model for intelligent reservoir fluid identification was constructed by incorporating the focal loss function.Comparative validations with five other models,including logistic regression(LR),naive Bayes(NB),gradient boosting decision trees(GBDT),random forest(RF),and support vector machine(SVM),show that this model demonstrates superior identification performance and significantly improves the accuracy of identifying oil-bearing fluids.Mutual information analysis reveals the model's differential dependency on various logging parameters for reservoir fluid identification.This model provides important references and a basis for conducting regional studies and revisiting old wells,demonstrating practical value that can be widely applied.
文摘Type 1 diabetes(T1D)is an autoimmune disease that usually strikes early in life,but can affect individuals at almost any age.It is caused by autoreactive T cells that destroy insulin-producing beta cells in the pancreas.Epidemiological studies estimate a prevalence of 1 in 300 children in the United States with an increasing incidence of 2%-5%annually worldwide.The daily responsibility,clinical management,and vigilance required to maintain blood sugar levels within normal range and avoid acute complications(hypoglycemic episodes and diabetic ketoacidosis)and long term micro-and macro-vascular complications significantly affects quality of life and public health care costs.Given the expansive impact of T1D,research work has accelerated and T1D has been intensively investigated with the focus to better understand,manage and cure this condition.Many advances have been made in the past decades in this regard,but key questions remain as to why certain people develop T1D,but not others,with the glaring example of discordant disease incidence among monozygotic twins.In this review,we discuss the field’s current understanding of its pathophysiology and the role of genetics and environment on the development of T1D.We examine the potential implications of these findings with an emphasis on T1D inheritance patterns,twin studies,and disease prevention.Through a better understanding of this process,interventions can be developed to prevent or halt it at early stages.

文摘Asian rice comprises two major subspecies:Xian(X)and Geng(G),and the diverged resistance genes(R)have provided a foundation for breeding improved cultivars to control rice blast disease.After conducting two-phase allele mining using six updated FNP marker systems,the functional haplotypes at Pit,Pib,and Pi63 strictly diverged into the X-populations and were defined as X-R loci,while those at Pi54,Pi37,and Pi36 into the G-populations as G-R loci.The genic diversity at the three X-R loci(16 alleles)was twofold higher than that at the three G-R loci(8 alleles),and the allelic diversity in the Southern region(21 alleles)was nearly double that in the Northeastern region(11 alleles).Both observations reflect a significant difference in genetic diversity between X-and G-populations,and indicate that the effective R-genes mainly originated from X-subspecies.Based on the allelic structures characterized by a set of 10 parameters,8 and 16 alleles were respectively recognized as favorable and promising ones for the regional breeding programs.The genotypic structures of the two regional populations were almost different,indicating that the diverged alleles have been further assembled into two series of regional genotypes through long-term breeding programs,despite the presence of one-third of region-common alleles.The genotypic diversity in the Southern region(55 genotypes)was nearly twice as high as that in the Northeastern region(28),which perfectly reflects the aforementioned differences in both genic and allelic diversities.After analyzing the genotypic structures using a set of 13 parameters,4 and 23 genotypes,respectively,can be recommended as the favorable and promising ones for the regional breeding programs.The case study serves as a concrete sample of how to identify the favorable and promising alleles and genotypes,and beneficial parents based their comprehensive population structures for gene-designed breeding.

文摘BACKGROUND Understanding the type and extent of coronary artery involvement in patients with acute type A aortic dissection(ATAAD)is vital for surgical planning.The Neri classification has been proposed as a guide for surgical strategies,however,its prognostic impact on postoperative mortality rates remains understudied in large-scale cohorts.METHODS We reviewed 600 ATAAD patients who underwent surgery and coronary computed tomography angiography from 2016 to 2020 at Fuwai Hospital,National Center for Cardiovascular Diseases,Chinese Academy of Medical Sciences and Peking Union Medical College,Beijing,China.Patients were classified based on the Neri classification system:no coronary artery involvement,type A(ostial involvement),type B(dissection in coronary body),and type C(circumferential detachment or complete avulsion).The primary endpoint was 30-day mortality.RESULTS Overall,28.3%of the patients had coronary artery involvement,with Neri type A,Neri type B,and Neri type C accounting for 13.3%,11.2%,and 3.8%,respectively.The right coronary artery was more frequently involved(25.3%)than the left coronary artery(8.0%).In the unadjusted analysis,patients with coronary artery involvement exhibited a numerically higher 30-day mortality compared to those without(5.3%vs.2.3%)(OR=2.35,95%CI:0.94–5.88,P=0.07),though this difference did not reach statistical significance.However,multivariable adjustment revealed significant association(adjusted OR=3.71,95%CI:1.05–13.13,P=0.04).Interestingly,after additional adjustment for coronary artery bypass grafting,the impact of coronary artery involvement on 30-day mortality no longer remained statistically significant(adjusted OR=3.13,95%CI:0.85–11.58,P=0.09).The 1-year mortality was higher in those with coronary artery involvement,but this significant association disappeared after adjusting for potential confounding variables.Furthermore,no significant difference in 30-day and 1-year mortality were observed among patients with different Neri classifications.CONCLUSIONS In patients with ATAAD who undergo surgery,the presence of coronary artery involvement is significantly associated with an increased risk of 30-day mortality.Proactive coronary artery bypass grafting may potentially mitigate the adverse impact of coronary artery involvement on 30-day mortality.

文摘BACKGROUND Exogenous insulin may trigger immune-mediated complications,particularly among East Asian populations.Double diabetes,characterized by overlapping features of type 1 diabetes(T1D)and type 2 diabetes(T2D),may arise from insulin-induced autoimmunity.This study aimed to explore the association between high-risk human leukocyte antigen(HLA)class Ⅱ genotypes and susceptibility to double diabetes in patients initially diagnosed with T2D.AIM To investigate clinical and immunogenic features of patients who develop double diabetes following exogenous insulin therapy.METHODS We retrospectively analyzed five cases from Peking Union Medical College Hospital and 18 cases identified from published literature.Patients were categorized into two groups:The T2D→T1D group,characterized by autoimmune progression,and the stable T2D(T2D→T2D).Clinical characteristics and HLA class Ⅱ genotypes were compared descriptively between the two groups.RESULTS A total of 23 patients were included in the analysis.Of these,10 progressed from theT2D→T1D with autoimmune features,while 13 remained in the stable T2D→T2D group.There was no statistically significant difference in age at diagnosis between the two groups(57.10±16.11 years vs 60.31±17.41 years).In the T2D→T1D group,70%of patients carried the HLA-DRB104:05 allele and 40%carried DRB109:01,both of which are commonly associated with a high risk of T1D.In contrast,the T2D→T2D group showed greater genetic heterogeneity,with a broader distribution of HLA-DRB1 alleles,including DRB103:02(n=4),DRB109:01(n=4),and several lower frequency alleles such as DRB1*04:05,*08:03,*03:01,*04:06,*14:01,*04:01,*12:02,*15:02 and*02:01.CONCLUSION These findings suggest that patients in the T2D→T1D group exhibit a stronger autoimmune genetic predisposition,characterized by an enrichment of high-risk HLA class II alleles.In contrast,individuals with stable T2D demonstrate greater HLA diversity and lack definitive autoimmune-associated markers.

文摘Osteoporosis represents a prevalent and debilitating comorbidity in patients diagnosed with type 2 diabetes mellitus(T2DM),which is characterized by suppressed osteoblast function and disrupted bone microarchitecture.In this study,we utilized male C57BL/6 J mice to investigate the role of SIRT3 in T2DM.Decreased SIRT3 expression and impaired mitochondrial quality control mechanism are observed in both in vitro and in vivo models of T2DM.Mechanistically,SIRT3 suppression results in hyperacetylation of FOXO3,hindering the activation of the PINK1/PRKN mediated mitophagy pathway and resulting in accumulation of dysfunctional mitochondria.Genetical overexpression or pharmacological activation of SIRT3 restores deacetylation status of FOXO3,thus facilitating mitophagy and ameliorating osteogenic impairment in T2DM.Collectively,our findings highlight the fundamental regulatory function of SIRT3 in mitochondrial quality control,crucial for maintaining bone homeostasis in T2DM.These insights not only enhance our understanding of the molecular mechanisms underlying diabetic osteoporosis but also identify SIRT3 as a promising therapeutic target for diabetic osteoporosis.

文摘Two sharp Chernoff type inequalities are derived for star bodies in R2,one is an extension of the dual Chernoff-Ou-Pan inequality,and the other is the reverse Chernoff type inequality.Furthermore,we establish a generalized dual symmetric mixed Chernoff inequality for two planar star bodies.As a direct consequence,a new proof of the dual symmetric mixed isoperimetric inequality is presented.
文摘Acceptor-donor-acceptor(A-D-A)type molecules,of which the novel non-fused azacyclic end-group pyrazoli-nones were modified with chlorine substitution on the phenyl ring,were synthesized.The non-fused azacyclic end-group py-razolinones have the advantages of simple synthesis steps,low cost and environmental friendliness,compared to the classical end-group dicyanomethyleneindianone.The properties of the synthesized A-D-A type molecules with non-fused azacyclic end groups were characterized by theoretical calculation,UV-vis absorption,cyclic voltammetry,X-ray diffraction and space charge limited current.It is shown that the strong UV-vis absorptions of the synthesized A-D-A type molecules are located in the wavelength range of 500~700 nm,with a moderate band gap of nearly 1.7 eV.At the same time,the influence of end-group chlorination on the properties of A-D-A type molecules was compared and explored.It is proven that this kind of A-D-A type molecule with non-fused azacyclic end groups has the potential to be applied as interfacial modified layer of the active layer in perovskite solar cell devices.

文摘Toxin–antitoxin(TA)systems,which are prevalent in bacteria and archaea,play diverse roles in bacterial physiology and have been proposed to be significant in stress adaptation.Despite the extensive characterization of numerous TA systems in various bacteria,the investigation of these systems within Streptococcus suis is still limited.Here,we systematically analyzed the type Ⅱ TA systems of 95 S.suis genomes available in the GenBank database using TAfinder.A total of 612 putative type Ⅱ TA systems were retrieved and classified into 10 categories by phylogenetic analysis.Notably,an elevated occurrence of these TA systems was observed among the important prevalent serotypes 2,4,5,9,14,Chz,NCL1,and NCL3 strains.The following study identified the activities of TA systems using 2 strategies and confirmed the regulatory effect of HigBA on the type Ⅶ secretion system in S.suis by measuringβ-galactosidase activity and transcriptional changes.Moreover,we unveiled a hitherto uncharacterized,highly prevalent novel TA system,with the composition of antitoxin–toxin–antitoxin(SS-ATA),which regulates the downstream two-component signaling system.Altogether,this study systematically analyzed the type Ⅱ TA systems within S.suis,highlighting the widespread distribution of Hig BA and SS-ATA as important regulatory elements in S.suis.
