Abstract

Premature children are more susceptible to neurodevelopmental risks than full-term children, due to exposure to numerous biological factors and unfavorable clinical outcomes, which can compromise motor, cognitive, and linguistic development. If neurodevelopmental alterations are detected early, it is possible to intervene and refer to interventions in the first months of life, optimizing benefits and reducing the risk of future disabilities. This literature review aims to describe the neurodevelopmental process of premature children, the unfavorable clinical outcomes associated with prematurity, and the neurological impairments that may occur in this group. The importance of this review lies in the need to understand the impacts of prematurity on child development, which enables the implementation of early interventions and effective strategies to mitigate risks and promote health development. Method: Online research was conducted in Medline, LILACS, Google Scholar, PubMed, and SciELO databases between January 2024 and January 2025, with references dated between 1978 and 2025 consisting of 127 articles, 07 official documents from government organizations, and 02 books. This narrative review approach the following topics: (1) neurogenesis; (2) child neurodevelopment; (3) motor, cognitive, and language development in premature children; (4) early diagnosis of premature children; (5) unfavorable clinical outcomes of prematurity, (6) neurological impairments in prematurity, (7) contextual factors and the development of premature children. The reviewed literature reinforces the need for continuous and specialized monitoring to ensure that premature children have access to adequate care and early interventions, which are crucial for their comprehensive development.

New strategic diplomatic relations between China and Russia: a model for Great Powers
Authors: Liu Yan 
Published: February 2025

The article is devoted to the analysis of the development of strategic relations between China and Russia, with an emphasis on the analysis of key documents and statements made by the heads of the two countries in the period from 1996 to 2025. It examines the evolution of the partnership between China and Russia, which has gone from the initial formation of the concept of "strategic" to the current "golden age" of "inclusiveness", when both countries established a cooperation in a complex and changing international context. These new interstate relations play a key role in responding to challenges in world politics, promoting economic cooperation, and ensuring global and regional security. The article emphasizes that Russian-Chinese relations have evolved from pragmatic cooperation in the economic sphere to a comprehensive strategic partnership, including coordination in the international arena. The theoretical basis is the relational theory of world politics by Qin Yaqing. The author also uses an interdisciplinary approach based on the methods of structural realism, historical-comparative and problem-chronological analysis. China and Russia view each other as priority partners, as evidenced by the growth of bilateral trade and joint efforts to create a new international order based on the principles of multipolarity and mutual respect. The paper identifies three key periods of development of Russian-Chinese cooperation: the initial stage (1996-2006), the phase of rapid growth (2006-2016) and the modern "golden period" of comprehensive partnership (2016–present). This study will provide a new perspective on the role of China and Russia in modern international relations. The article concludes that Russian-Chinese relations represent a unique model of cooperation between great powers based on equality, trust and mutual benefit. In the future, the author predicts further strengthening of cooperation in the political, economic and military spheres, as well as increased coordination within international organizations such as the United Nations, BRICS and SCO.

O texto apresenta um diálogo entre duas pesquisas em desenvolvimento pela Universidade do Estado do Rio de Janeiro, Faculdade de Formação de Professores/as, Programa de Pós-Graduação em Educação - Processos Formativos e Desigualdades Sociais, com a metodologia de pesquisa narrativa (auto)biográfica (Bragança, Prado, Araújo, 2021), onde uma professorapesquisadora[1], outrora estudante, viveu o processo de reconhecer quem se é, atravessada às falas libertadoras de sua então professora da classe de alfabetização, numa escola envolta à natureza. A mesma busca reconhecer se as recordações-referências de docentes em épocas de estudantes reverberam em suas práticas atuais. Esta pesquisa vai de encontro às narrativas da segunda professorapequisadora atuante na Orientação Educacional, porque esta última traz as narrativas dos/as meninos/as da rede municipal de Maricá, no distrito de Itaipuaçu, no Campus de Educação Pública Transformadora Leonel de Moura Brizola, estado do Rio de Janeiro, no ano de 2023, local este de belezas naturais. E tem como questionamento: Por que crianças do 5º ano escolar estão em processo inicial de apropriação do código alfabético? Será que esses estudantes leem o mundo, como fez a menina Canela? As pesquisas dialogam, pois os/as menino/as, estudantes do processo de alfabetização, tem também no território ao redor de sua escola um espaço de natureza e o diálogo com uma professora, como outrora a menina Canela, e buscam a partir da relação dialógica, inspiradas pelos estudos freirianos, a educação como libertação coletiva.
Frequency and significance of preterm delivery in twin pregnancies

Published: July 2002

AbstractObjective: We investigated the frequency of preterm delivery and its influence on the neonatal outcome in twin pregnancies at a perinatal center. Are there differences in the course of twin pregnancies with preterm or term delivery? Method: A retrospective investigation was carried out at the Department of Obstetrics on 502 twin pregnancies and deliveries between 1978 and 1993. Pregnancy history and clinical parameters were compared among preterm (<37+0 weeks) and term deliveries. Result: Median duration of all twin pregnancies was 36+3 weeks of gestation. In the preterm group, preterm labor was more frequent, both, the first and the second neonate had lower birth weight and were more often admitted to the neonatal intensive care unit (NICU) where they stayed longer than full‐term neonates needing intensive care. Perinatal deaths occurred only in the preterm group. Conclusions: The incidence of preterm delivery is significantly elevated in twin pregnancies and consequently the incidence of low‐ and very‐low‐birth‐weight‐infants and perinatal mortality. Preterm delivery is the main reason why twin pregnancies are at a higher risk for an adverse neonatal outcome and thereby cause considerable costs.
Cell Segregation and Lysis Have Profound Effects on the Growth of Escherichia coli in High Cell Density Fed Batch Cultures
Authors: Andersson Lena , Strandberg Lars , Enfors Sven‐Olof 
Published: July 2002

AbstractCell segregation into nondividing states and lysis was found to dominate the growth behavior of high cell density fed batch cultures of Escherichia coli. When the specific growth rate declined below a critical value, the biomass production, oxygen consumption, and carbon dioxide formation rates declined sharply. Concomitantly, an extensive loss of colony‐forming ability (cfu) and accumulation of extracellular proteins was observed. A segregated model that considered different physiological states, including dividing, nondividing, and lysed cells, was developed and applied to experimental data from high cell density cultures of E. coli.
Influence of Polymer Structure on Protein Partitioning in Two‐Phase Aqueous Systems

Published: July 2002

AbstractCopolymers of acrylamide and styrene with two distinct structures were synthesized to study the effect of polymer structure on protein partitioning in two‐phase aqueous systems. Micellar copolymerization was used to prepare a multiblock copolymer, while homogeneous copolymerization was used to prepare a random copolymer, both with the same composition and molecular weight. Phase behavior studies of the copolymers with poly(ethylene glycol) in water showed little difference in the phase boundaries. However, the partitioning of bovine serum albumin between the two aqueous phases was sensitive to the polymer structure. A molecular picture is proposed for the interactions between the protein and block copolymers. The effect of pH on the protein partition is analyzed in terms of the hydrophobic interactions, and the polymer and protein partitioning was correlated using a model based on the Flory−Huggins theory.

AbstractPurposeThe objective of this study was to fabricate an anthropomorphic multimodality pelvic phantom to evaluate a deep‐learning‐based synthetic computed tomography (CT) algorithm for magnetic resonance (MR)‐only radiotherapy.MethodsPolyurethane‐based and silicone‐based materials with various silicone oil concentrations were scanned using 0.35 T MR and CT scanner to determine the tissue surrogate. Five tissue surrogates were determined by comparing the organ intensity with patient CT and MR images. Patient‐specific organ modeling for three‐dimensional printing was performed by manually delineating the structures of interest. The phantom was finally fabricated by casting materials for each structure. For the quantitative evaluation, the mean and standard deviations were measured within the regions of interest on the MR, simulation CT (CTsim), and synthetic CT (CTsyn) images. Intensity‐modulated radiation therapy plans were generated to assess the impact of different electron density assignments on plan quality using CTsim and CTsyn. The dose calculation accuracy was investigated in terms of gamma analysis and dose‐volume histogram parameters.ResultsFor the prostate site, the mean MR intensities for the patient and phantom were 78.1 ± 13.8 and 86.5 ± 19.3, respectively. The mean intensity of the synthetic image was 30.9 Hounsfield unit (HU), which was comparable to that of the real CT phantom image. The original and synthetic CT intensities of the fat tissue in the phantom were −105.8 ± 4.9 HU and −107.8 ± 7.8 HU, respectively. For the target volume, the difference in D95% was 0.32 Gy using CTsyn with respect to CTsim values. The V65Gy values for the bladder in the plans using CTsim and CTsyn were 0.31% and 0.15%, respectively.ConclusionThis work demonstrated that the anthropomorphic phantom was physiologically and geometrically similar to the patient organs and was employed to quantitatively evaluate the deep‐learning‐based synthetic CT algorithm.

Published: May 2022

AbstractChiral lead halide perovskites (LHPs) possess natural optical activities (NOA), which are determined by the chirality‐induced spin–orbit coupling (SOC). This makes them potentially useful for chiroptical spintronic applications. Here, the effective manipulation of magneto‐photoluminescence (magneto‐PL) by circularly polarized light for chiral LHP single crystals, such as (R‐MBA)2PbI4 and (S‐MBA)2PbI4, is demonstrated. A large and negative magneto‐PL effect with a magnitude of 7% can be detected at the field strengths of ±900 mT at 4 K. The change of the magneto‐PL that is due to the left and right photoexcitation of circularly polarized light (σ + and σ −) can reach 37.3%. Such an effect can be well elucidated by the recently developed theoretical model based on a field‐induced population difference at exciton states. It is found that the Landé g‐factors of photogenerated paramagnetic species and electron–hole pair lifetimes (τ) obey circular dichroism (CD). The results indicate that chirality can be indelibly imprinted on the photogenerated species. The work paves the way for the light and field manipulation of large magneto‐PL for the chiral LHPs in applications of chiroptical spintronics.

AbstractStrontium cobalt oxide is an important perovskite‐type material in the research of solid oxide fuel cells (SOFCs), since a great number of derived cathode materials can be obtained through composition modification against SrCoO3‐δ (SCO). In this work, pristine SCO without any additional dopants was synthesized, and its electrochemical properties were evaluated according to the electrochemical impedance spectroscopies (EIS) analyses through the distribution of relaxation times (DRT) method on the symmetrical cells. The undoped SCO displayed low polarization resistances as well as a high oxygen transport ability, even comparable to the famous cathode, Sm0.5Sr0.5CoO3‐δ (SSC). Oxygen surface and bulk diffusion were found to be the dominating processes in the oxygen reduction reaction (ORR) of SCO. These results could broaden our knowledge about the ionic transport behavior of SCO‐based perovskite materials.
Progressive damage and tensile failure of open‐hole carbon fiber polymer composites reinforced by carbon nanotubes
Authors: Han Kang‐ning , Zhou Wei , Ding Zhen‐jun 
Published: May 2022

AbstractProgressive damage and tensile failure of open‐hole carbon fiber/carbon nanotube reinforced composites with different off‐axis angles were detected by acoustic emission and Micro‐CT. K‐mean clustering algorithm can be utilized to post‐process signals of acoustic emission. Three critical points including linear growth point, near maximum load point and failure point, were selected to study progressive damage. Results indicated that stiffness variable decreased with the increase of off‐axis angle. When the off‐axis angle was 0°, higher initial stress and catastrophic brittle fracture characteristics can be obtained, whereas pseudo‐ductile behavior can be observed when off‐axis angles were 30° and 45° because of the alignment of yarn (fiber trellising) and the matrix plasticity. Due to the symmetrical structure of plain texture, there was a very interesting phenomenon that the tensile strength of composite specimen with 45° off‐axis angle was 23.65% higher than that of the specimen with an off‐axis angle of 30°. In the second stage of loading, the slope drop sharply when the load reached first key point, and Kaiser Effect can be observed. Acoustic emission technology and Micro‐CT method are beneficial to damage assessment of complex composites.

Published: May 2022

AbstractFluorescent probes have been powerful tools for visualizing and quantifying multiple dynamic processes in living cells. However, the currently developed probes are often constructed by conjugation a fluorophore with a recognition moiety and given signal‐output after triggering with one singly target interest. Compared with the single‐target‐activated fluorescent probes mentioned above, the dual‐target‐activated ones, triggering with one target under stimulus (such as photoirradiation, microenvironment) or another targets, have the advantages of advoiding nonspecific activation and “false positive” results in complicated environments. In recent years, many dual‐target‐activated fluorescent probes have been developed to detect various biologically relevant species. In view of the importance of a comprehensive understanding of dual‐target‐ activated fluorescent probes, a thorough summary of this topic is urgently needed. However, no comprehensive and critical review on dual target activated fluorescent probes has been published recently. In this review, we focus on the dual‐target‐activated fluorescent probes and briefly outline their types and current state of development. In each type, the chemical structure, proposed responsive mechanism and application of probes are highlighted. At last, the challenges and prospective opportunities of every type were proposed.
Identifying of Pure and Defected Ti2C Materials Using Gas Probe Molecules: First Principles Calculations
Authors: Zhang Fengxiang , Song Ziyue , Hu Wei , Zhang Yujin 
Published: May 2022

AbstractEmploying first principles calculations, we systematically investigated the geometrical and electronic structures of pure, titanium defected (DTi) and carbon defected (DC) Ti2C materials. We found the defected Ti2C exhibits stronger metallic property than pure Ti2C due to the enhanced density of Ti‐d orbital state near the Fermi level. We then studied the adsorption as well as the infrared spectrum (IR) response of the four kinds of gas molecules (CH4, NH3, CO and NO) on pure, DTi and DC Ti2C surfaces. Simulations show that CO and NO molecules are chemically adsorbed on all Ti2C surface with similar adsorption sites. However, CH4 and NH3 molecules would be dissociated on Ti2C surface. Negative values of crystal orbital Hamilton population as well as the PDOS calculations show that the red shift in IR spectra of CO and NO molecules originates from the decreasing bonding strength of probe molecules. The present work provides rich insight for the adsorption and identification for different Ti2C materials.
Importance of ocean prediction for heavy rainfall prediction over Japan in July 2020
Authors: Baba Yuya 
Published: May 2022

AbstractHindcast experiments were performed for heavy rainfall events over Japan in July 2020 using a regional atmospheric model and a regional coupled model to examine the importance of ocean prediction for predicting heavy rainfall events. Both models were able to predict the first peak of accumulated rainfall over western Japan occurring in the first half of July. However, only the coupled model predicted the second peak that occurred in the second half of July. Sea level pressure (SLP) and low‐level moisture inflow originating from an existing atmospheric river (AR) were found to differ in each model. In the regional atmospheric model, the error associated with the inaccurate low‐level moisture inflow grew with rising excessive latent heat flux, which enhanced convection and resulted in incorrect SLP patterns. This trend seems to be enhanced by having a prescribed sea surface temperature (SST), which affects the surface heat flux. When ocean conditions are predicted as in the coupled model, such error growth is suppressed by changes in SST that adjust surface heat flux, and it leads to generation of the correct SLP patterns. With correct SLP especially for Pacific high in this case, favorable conditions for inflow from the AR can also be predicted, thus making it possible to predict the heavy rainfall. In conclusion, considering the atmospheric feedback on SST, ocean prediction can improve the predictability of heavy rainfall over Japan, the conditions for which are influenced by the nearby AR. Ocean prediction may therefore extend the range of weather forecasting.
Bayesian two‐stage sequential enrichment design for biomarker‐guided phase II trials for anticancer therapies

Published: May 2022

AbstractBiomarker‐guided phase II trials have become increasingly important for personalized cancer treatment. In this paper, we propose a Bayesian two‐stage sequential enrichment design for such biomarker‐guided trials. We assumed that all patients were dichotomized as marker positive or marker negative based on their biomarker status; the positive patients were considered more likely to respond to the targeted drug. Early stopping rules and adaptive randomization methods were embedded in the design to control the number of patients receiving inferior treatment. At the same time, a Bayesian hierarchical model was used to borrow information between the positive and negative control arms to improve efficiency. Simulation results showed that the proposed design achieved higher empirical power while controlling the type I error and assigned more patients to the superior treatment arms. The operating characteristics suggested that the design has good performance and may be useful for biomarker‐guided phase II trials for evaluating anticancer therapies.
