The art of constructing an insightful literature review manuscript has witnessed an exemplar in the work of Oz et al(2023),wherein concept progression harmoniously merges with figures and tables.Reflecting on retrospective data science,it is evident that well-cited articles can wield a transformative influence on the Journal Citation Reports Impact Factor score,as exemplified by Robert Weinberg’s landmark on cancer(Hanahan and Weinberg,2011).Here,we aim to spotlight a commendable contribution by Tuba Oz,Ajeet Kaushik,and Małgorzata Kujawska in this issue while pivoting towards identifying the hallmarks of a subpar literature review-elements that hinder rather than promote advancement.The hurdles and roadblocks encountered within subpar literature reviews are multifold.Anticipation of emerging trends,identification of challenges,and exploration of solutions remain conspicuously absent.Original Contributions fail to surface amidst the vast sea of pre-existing literature,with noticeable gaps amplified by the lack of illustrative figures and tables.The manuscript,at times,assumes a skeletal form,reflecting an attempt to accommodate an excess of references,leading to convoluted sentences laden with citations.In contrast,a potent solution lies in adopting a comprehensive approach.A nuanced and critical evaluation of sources can culminate in a robust discussion,surpassing the mere summarization of conclusions drawn by others.This approach,often dismissed,holds the potential to elevate clarity,coherence,and logical flow,ultimately inviting engaged readership and coveted citations.The critical necessity of integrating visionary insights is underscored and achieved through a rigorous analysis of pivotal concepts and innovative ideas.Examples can be harnessed to elucidate the application of these solutions.We advocate a paradigm shift,urging literature review writers to embrace the readers’perspective.A literature review’s purpose extends beyond providing a comprehensive panorama;it should illuminate avenues for concept development within a specific field of interest.By achieving this balance,literature reviews stand to captivate a devoted readership,paving the way for manuscripts that are both widely read and frequently cited.The pathway forward requires a fusion of astute analysis and visionary insights,shaping the future of literature review composition. 展开更多

Based on the theory of structural analysis,the characteristics and structural patterns of subtle faults are studied using 3D seismic data of the Bohai Sea to analyze the development process and origin of the subtle faults.A method of identifying subtle faults is proposed,forming a complete system for analyzing origins of subtle faults in the Bohai Sea.The complex strike-slip fault patterns under the strike-slip and extension stress background,diverse formation rocks,and strong neotectonic movement are the reasons for the development of subtle faults.According to the tectonic origin and development location,the subtle faults in Bohai Sea can be divided into 12 types in the three categories of strike slip dominant,extension dominant and strike slip and extension composite,and the different types of subtle faults occur in different regions of the Bohai Sea.Unreasonable variation of sedimentary stratum thickness,inherited distortion or even abrupt change of stratum occurrence,zonation of plane fault combination and the variation of oil-water system in the same structure with no-lithologic change are the important signs for identifying subtle faults in Bohai Sea.The subtle faults greatly enlarge the size of the structural trap groups,and areas with dense subtle faults are often active area of hydrocarbon migration and accumulation and favorable exploration zones,which have strong control on the hydrocarbon accumulation.The identification method for subtle faults has guided the exploration in the mature areas of Bohai Sea effectively,with a number of large and medium oil and gas fields discovered,such as Bozhong 29-6 and Penglai 20-2. 展开更多

The Yiddish language originated in Ashkenazi culture and is spoken by Ashkenai Jewish who are thought to be the descendants of Rhineland Jews. For years, it was carried to many parts of the world with the migration of these Ashkenazi Jewish and a real version of ups and downs of the people. It was once considered as a dialect of German rather than an independent language, which many scholars of Ashkenazi Jewish origin managed to get rid of. It aims to give a brief introduction to this language and try to trace back its origin and development so as to bring a brief senario of the Ashkenazi Jewish's striving for their identity. Having read and study literatures about this language, a conclusion can be reached that Yiddish language means"the mother tongue of Jewish people"which reflects Jewish cultural life and finally prove its value that it deserved in fields of linguistics and literature through centuries-long wax and wane. 展开更多

The developmental origins of health and diseases(DOHaD)is a concept stating that adverse intrauterine environments contribute to the health risks of offspring.Since the theory emerged more than 30 years ago,many epidemiological and animal studies have confirmed that in utero exposure to environmental insults,including hyperglycemia and chemicals,increased the risk of developing noncommunicable diseases(NCDs).These NCDs include metabolic syndrome,type 2 diabetes,and complications such as diabetic cardiomyopathy.Studying the effects of different environmental insults on early embryo development would aid in understanding the underlying mechanisms by which these insults promote NCD development.Embryonic stem cells(ESCs)have also been utilized by researchers to study the DOHaD.ESCs have pluripotent characteristics and can be differentiated into almost every cell lineage;therefore,they are excellent in vitro models for studying early developmental events.More importantly,human ESCs(hESCs)are the best alternative to human embryos for research because of ethical concerns.In this review,we will discuss different maternal conditions associated with DOHaD,focusing on the complications of maternal diabetes.Next,we will review the differentiation protocols developed to generate different cell lineages from hESCs.Additionally,we will review how hESCs are utilized as a model for research into the DOHaD.The effects of environmental insults on hESC differentiation and the possible involvement of epigenetic regulation will be discussed. 展开更多

It is based on people's ambitions for a better life and carries beautiful wishes. These beautiful roots are ultimately derived from "love", in the dance based on the image of people. Dance art expresses the love between people, the love of human and nature, the love of human and society;in the dance works based on the object, the intrinsic connection between nature and the natural world is also reflected. This paper expounds the cognition of dance in terms of children's dance enlightenment, limb development, aesthetic education, etc., and promotes the continuous development of the dance cause, cultivates more outstanding dancers, and creates more excellent dance works. 展开更多

Emerging evidence is fueling a new appreciation of oligodendrocyte diversity that is overturning the traditional view that oligodendrocytes are a homogenous cell population.Oligodendrocytes of distinct origins,maturational stages,and regional locations may differ in their functional capacity or susceptibility to injury.One of the most unique qualities of the oligodendrocyte is its ability to produce myelin.Myelin abnormalities have been ascribed to a remarkable array of perinatal brain injuries,with concomitant oligodendrocyte dysregulation.Within this review,we discuss new insights into the diversity of the oligodendrocyte lineage and highlight their relevance in paradigms of perinatal brain injury.Future therapeutic development will be informed by comprehensive knowledge of oligodendrocyte pathophysiology that considers the particular facets of heterogeneity that this lineage exhibits. 展开更多

The flower is an evolutionary innovation in angiosperms that drives the evolution of biodiversity.The carpel is integral to a flower and develops into fruits after fertilization,while the perianth,consisting of the calyx and corolla,is decorative to facilitate pollination and protect the internal organs,including the carpels and stamens.Therefore,the nature of flower origin is carpel and stamen origin,which represents one of the greatest and fundamental unresolved issues in plant evolutionary biology.Here,we briefly summarize the main progress and key genes identified for understanding floral development,focusing on the origin and development of the carpels.Floral ABC models have played pioneering roles in elucidating flower development,but remain insufficient for resolving flower and carpel origin.The genetic basis for carpel origin and subsequent diversification leading to fruit diversity also remains elusive.Based on current research progress and technological advances,simplified floral models and integrative evolutionary-developmental(evodevo)strategies are proposed for elucidating the genetics of carpel origin and fruit evolution.Stepwise birth of a few master regulatory genes and subsequent functional diversification might play a pivotal role in these evolutionary processes.Among the identified transcription factors,AGAMOUS(AG)and CRABS CLAW(CRC)may be the two core regulatory genes for carpel origin as they determine carpel organ identity,determinacy,and functionality.Therefore,a comparative identification of their protein-protein interactions and downstream target genes between flowering and non-flowering plants from an evo-devo perspective may be primary projects for elucidating carpel origin and development. 展开更多
