To quantify the pore characteristics of various macerals in Chang 7 lacustrine shales,macerals were effectively identified according to their optical and morphological characteristics,and the nanoscale pore structure of macerals was observed by scanning electron microscope.Meanwhile,the reflectances of different positions in the same pieces of vitrinite or solid bitumen with heterogeneous pores development were measured.The results showed that the average contents of sapropelinite,liptinite,vitrinite,inertinite and solid bitumen are 42.7%,8.7%,13.6%,13.8% and 21.2%,respectively,which suggests that the source of the organic matter of the Chang 7 shales is a mixed source input.The organic pores of Chang 7 shales are enriched,and the pore shapes are mostly round or elliptical.The pore size of organic pores has a wide distribution,mainly concentrate in the range of 100-400 nm,and the average plane porosity of organic pores is 10.13%.The size order of the organic pores in various macerals is:solid bitumenfusinite>bituminite>solid bitumen>vitrinite>liptinite.OM pores are mainly contributed by bituminite,solid bitumen and fusinite.The plane porosity of bituminite increases with maturity.In the process of thermal evolution,the plane porosity of fusinite is distributed in the two ranges of 20%-28% and 1%-7%.The former is mainly the primary pores of the fusinite itself,and the latter is the secondary pores formed in the thermal evolution.As for the organic pores of other macerals,no obvious thermal evolution law was found.Meanwhile,the surface imperfections of vitrinite or solid bitumen is enhanced by the enrichment of organic pores(an increase in pore size or pore number),which may result in the underestimation of their reflectances.

Here,through single-molecule real-time sequencing,we present a high-quality genome sequence of the Japanese larch(Larix kaempferi),a conifer species with great value for wood production and ecological afforestation.The assembled genome is 10.97 Gb in size,harboring 45,828 protein-coding genes.Of the genome,66.8%consists of repeat sequences,of which long terminal repeat retrotransposons are dominant and make up 69.86%.We find that tandem duplications have been responsible for the expansion of genes involved in transcriptional regulation and stress responses,unveiling their crucial roles in adaptive evolution.Population transcriptome analysis reveals that lignin content in L.kaempferi is mainly determined by the process of monolignol polymerization.The expression values of six genes(LkC OMT7,LkC OMT8,LkL AC23,LkL AC102,LkP RX148,and LkP RX166)have significantly positive correlations with lignin content.These results indicated that the increased expression of these six genes might be responsible for the high lignin content of the larches’wood.Overall,this study provides new genome resources for investigating the evolution and biological function of conifer trees,and also offers new insights into wood properties of larches.

This study was designed to investigate effect of chronic intermittent hypobaric hypoxia(CIHH) on carotid sinus baroreflex(CSB) using Perfusion technique in isolated carotid sinus area in fructose-induced metabolic syndrome(Mets) rats.Sprague-Dawley rats were subject to treatment with fructose(10%fructose in drinking water for 6 weeks),CIHH(simulated 5000 m altitude,6 hours per day for 6 weeks),and CIHH plus fructose.CSB was inhibited in fructose-induced Mets rats and enhanced in CIHH treated rats.The inhibition of CSB by fructose treatment was lightened in CIHH plus fructose treated rats.The facilitation of CSB in CIHH treated rats was partly abolished by Glibenclamide,a ATP sensitive potassium channel(K) blocker.The results suggest that CIHH can antagonize the inhibition of CSB in Mets rats,which is related to the opening of K channel.

The pervasive utilization of industrial substances has escalated human exposure to cadmium(Cd),a metal associated with long-term negative health outcomes such as renal dysfunction,neurological disorders,and various cancers^([1]).Once ingested by humans,Cd interacts with cysteine-rich metallothioneins(MTs)which have metal-binding and antioxidant properties and is subsequently transported to the kidney^([2]).

LetΩbe a bounded smooth domain in RN(N≥3).Assuming that 00 are constants,we consider the existence results for positive solutions of a class of fractional elliptic system below,{(a+b[u]^(2)_(s))(-Δ)^(s)u=vp+h_(1)(x,u,v,▽u,▽v),x∈Ω,(-Δ)^(s)v=u^(q)+h_(2)(x,u,▽,▽u,▽v),x∈Q,u,v>0,x∈Ω,u=v=0,x∈RN\Ω.Under some assumptions of hi(x,u,v,▽u,▽v)(i=1,2),we get a priori bounds of the positive solutions to the problem(1.1)by the blow-up methods and rescaling argument.Based on these estimates and degree theory,we establish the existence of positive solutions to problem(1.1).

Asian Journal of Andrology 2024年第1期26卷 1-9页

作者： hui Luo Ke-Cheng Lou Ling-Yu xie Fei Zeng Jun-Rong Zou The First Clinical College Gannan Medical UniversityGanzhou 341000China Department of Urology The First Affiliated Hospital of Gannan Medical UniversityGanzhou 341000China Institute of Urology The First Affiliated Hospital of Gannan Medical UniversityGanzhou 341000China Jiangxi Engineering Technology Research Center of Calculi Prevention Ganzhou 341000China

Urethral stricture is characterized by the chronic formation of fibrous tissue,leading to the narrowing of the urethral lumen.Despite the availability of various endoscopic treatments,the recurrence of urethral strictures remains a common challenge.Postsurgery pharmacotherapy targeting tissue fibrosis is a promising option for reducing recurrence rates.Although drugs cannot replace surgery,they can be used as adjuvant therapies to improve outcomes.In this regard,many drugs have been proposed based on the mechanisms underlying the pathophysiology of urethral stricture.Ongoing studies have obtained substantial progress in treating urethral strictures,highlighting the potential for improved drug effectiveness through appropriate clinical delivery methods.Therefore,this review summarizes the latest researches on the mechanisms related to the pathophysiology of urethral stricture and the drugs to provide a theoretical basis and new insights for the effective use and future advancements in drug therapy for urethral stricture.

Neuroimmune interactions and their roles in neurodegenerative diseases

Fundamental Research 2024年第2期4卷 251-261页

作者： Bai-Rong Chen Ting Wu Ting-hui Chen yun Wang Neuroscience Research Institute and Department of Neurobiology School of Basic Medical SciencesKey Laboratory for NeuroscienceMinistry of Education/National Health Commission and State Key Laboratory of Natural and Biomimetic DrugsPeking UniversityBeijing 100083China PKU-IDG/McGovern Institute for Brain Research Peking UniversityBeijing 100871China

The nervous system possesses bidirectional,sophisticated and delicate communications with the immune system.These neuroimmune interactions play a vitally important role in the initiation and development of many disorders,especially neurodegenerative diseases.Although scientific advancements have made tremendous progress in this field during the last few years,neuroimmune communications are still far from being elucidated.By organizing recent research,in this review,we discuss the local and intersystem neuroimmune interactions and their roles in Alzheimer’s disease,Parkinson’s disease and amyotrophic lateral sclerosis.Unveiling these will help us gain a better understanding of the process of interplay inside the body and how the organism maintains homeostasis.It will also facilitate a view of the diseases from a holistic,pluralistic and interconnected perspective,thus providing a basis of developing novel and effective methods to diagnose,intervene and treat diseases.

作者： Lili hui Huobao xie Xiaofang Chen School of Management Wuhan University of TechnologyWuhanChina Research Institute of Digital Governance and Management Decision Innovation Wuhan University of TechnologyWuhanChina School of Economics and Management Wuhan UniversityWuhanChina

The deep integration of digital technology with the real economy has reconstructed production systems.We explore the impact of digital technology on the resource allocation behavior and efficiency of manufacturing enterprises.Using a sample of Chinese A-share listed manufacturing firms over the 2010–2021 period,we find that digital technology alleviates cost stickiness,especially in enterprises with a high level of Industrial Internet platform usage.This effect occurs by optimizing the labor force structure and improving the economic benefits of labor capital investment.Heterogeneity analysis shows that this effect is pronounced in enterprises with high levels of labor intensity and business complexity.Our findings shed new light on the consequences and mechanism of enterprise cost optimization that is driven by technologydriven reforms.
