Early Intervention Facilitates Neuropsychological Development in Children with Autism and Attention Deficit Hyperactivity Disorder

Objective:This study aims to investigate the impact of early intervention on neuropsychological development in children with autism and attention deficit hyperactivity disorder(ADHD),providing effective intervention strategies for clinical practice.Methods:A total of 130 children with autism and ADHD who visited the hospital between June 2023 and June 2024 were selected as study subjects and randomly divided into an intervention group and a control group,with 65 children in each group.The intervention group received a one-year early comprehensive intervention,including behavioral therapy,cognitive training,and family guidance,while the control group only received routine medical care.The neuropsychological development assessment scale was used to evaluate both groups before and after the intervention to compare changes in their neuropsychological development levels.Results:Children in the intervention group showed significant improvements in cognitive function,social skills,language ability,and attention concentration,with an average improvement score of 23.5 points.Children in the control group did not show significant improvements in these areas,with an average improvement score of only 5.8 points.The difference between the two groups was statistically significant(P<0.05).Conclusion:Early comprehensive intervention has a significant promoting effect on the neuropsychological development of children with autism and ADHD.Targeted behavioral therapy,cognitive training,and family guidance can effectively enhance children’s cognitive,social,language,and attention abilities,laying a solid foundation for their future overall development.Therefore,it is recommended to actively promote and apply early intervention strategies in clinical practice.

THE STUDY OF EARLY DEVELOPMENT AND EVOLUTION OF Torrentophryne aspinia

Torrentophryne aspinia is a new kind of toads discovered in China recently, it lives in the forest floor in West Yunnan, the most important things for this kind of species is that they have a kind of torrent-adapted tadpoles which have abdominal suckers and can adhere to the surfaces of rocks in moving waters. In this article, we described the forming procedures of abdominal sucker and some breeding behaviors, habitats and habits. After comparing with those of other toads, it is confirmed that Torrentophryne should be a new valid genus, it is derived from ancestor toads because of adaptation to the torrent habitats, by the forming of torrent -adapted organ-abdominal sucker in the early development.

Enantiornithine Bird with Diapsidian Skull and Its Dental Development in the Early Cretaceous in Liaoning, China

A Iarge number of enantiornithine birds are discovered from the Early Cretaceous Jiufutang Formation in western Liaoning, China. They are all small-sized birds with a few small teeth. The enantiornithine bird from the Jiufutang Formation in the Shangheshou area, Chaoyang, Liaoning Province reported in this paper is the largest individual known in all enantiornithine birds of the Early Cretaceous. However, its teeth possess a feature of pseudoheterodont. Some different development stages of the new teeth substitute the earlier stages and the stages of development are preserved in this specimen. This development pattern is similar to that of Archaeopteryx and alligator but not dinosaur. A well-developed postorbital was also preserved in the skull, which was a diapsidian skull like that of Confuciusornis. Additionally, the distinctive preservation of its prefrontal distinguishes it from other enantiornithine birds of the Early Cretaceous.

The role of Dby mRNA in early development of male mouse zygotes

Ejaculated mammalian spermatozoa contain a complex yet specific population of mRNA. However, the possible roles that mRNA has in early zygotic and embryonic development remain unclear. We found that Dby mRNA is selectively retained in capacitated mouse spermatozoa, and is transferred into the oocyte during fertilization by reverse transcription-polymerase chain reaction even though no DBY protein expression is detected. The cellular location ofDby mRNA is seen in the post-acrosome region, and it comprises nearly half of the mouse spermatozoa in in situ hybridization. In contrast, transcripts of the control gene, Smcy, are not detected in capacitated mouse spermatozoa, although the H-Y antigen encoded by Smcy is expressed on the surface of the spermatozoa. In our microinjection experiment, the zygotic development rate of the as-Dby male pronucleus injection group was significantly lower than that of the as-Smcy male pronucleus injection group （35.9% vs. 95%, P = 0.001） and the as-Dby female pronucleus injection group （35.9% vs. 93.8%, P = 0.001）. The rate of male-developed zygotes was also lower than that of the as-Smcy male pronucleus injection group （17.4% vs. 57.9%, P = 0.002） and the as-Dby female pronucleus injection group （17.4% vs. 54.1%, P = 0.002）. Thus, we conclude that Dby mRNA is selectively retained in capaci- tated mouse spermatozoa, and it has an important role in the early zygotic development of male mouse zygotes. This might imply that spermatozoa mRNA is involved in early zygotic and embryonic stages of reproduction.

STUDY ON EMBRYONIC DEVELOPMENT AND EARLY GROWTH OF TRIPLOID AND GYNOGENETIC DIPLOID LEFT-EYED FLOUNDER, PARALICHTHYS OLIVACEUS (T. et S.)

The early effects of chromosomal manipulation of eggs and sperm on the yields of triploid and gynogenetic diploid larvae of Paralichthys olivaceus were investigated. Triploidy was achieved by cold shocking fertilized eggs at 0-2℃ for 45 minutes duration 5 minutes after fertilization, and the induced triploidy rates were 31.2%-50% and the relative hatching rates were 53.3%-99%. Gynogenetic diploids were obtained when eggs were inseminated with irradiated sperm and cold shocked at 0-2℃ for 45 minutes duration 5 minutes after fertilization. The induced gynogenetic diploid rates and the relative hatching rates were 94%-96% and 48.5%-68.5% respectively. The embryonic development of the triploid experimental group and of the gynogenetic diploid experimental group was delayed at first compared with the control group. But from the gastrula stage, it was not delayed anymore. There were no significant differences in the growth of the triploid experimental group larvae and the control group larvae, and in the growth of the gynogenetic diploid experimental group larvae and the control group larvae according to Student’s t test (α=0.05). The relationship between the early growth of the triploid experimental group larvae and that of gynogenetic diploid experimental group larvae was also studied.

Antibodies against the C-terminal peptide of rabbit oviductin inhibit mouse early embryo development to pass 2-cell stage

A full-length rabbit oviductin cDNA(1909bp) was cloned. It consists of a 5’-UTR of 52bp, an open reading frame (ORF) of 1374bp and a 3’-UTR of 483bp and has more than 80% homology with that of other mammal oviductins. N-terminal peptide (NTP) (384 residues) and C-terminal peptide (CTP) (73 residues) of deduced protein precursor has about 80% and 50% identity with that of other mammals respectively. Fusion proteins GST-NTP 368(1R-368N)and GST-CTP73 (369F-441A) were expressed and purified. NH2-terminal of CTP sequencing reveals that the purified protein is consistent with the deduced one. In order to study the function of NTP and CTP the mouse anti-NTP and rabbit anti-CTP antisera were prepared. Tissue-specific (skeleton muscle, oviduct, uterus, ovary, liver, heart and brain) analysis indicated that rabbit oviductin was only found in oviduct. The conditioned medium derived from the rabbit oviduct mucosa epithelial cells has a function of overcoming the early embryonic development block of Kunming mous e cultured in vitro. Anti-CTP antiserum could totally inhibit the early embryo development at 2-cell stage cultured in the conditioned culture medium, but anti-NTP antiserum couldn’t. There was a positive relationship between the ratio of early embryos at development block and the dosage of anti-CTP antiserum added in the conditioned culture medium. These results suggest that oviductin has a function not only on fertilization, but also on the release of early embryonic development block, and the later function domain of rabbit oviductin may be situate in its C-terminal.

Evaluation of reference genes for quantitative real-time PCR analysis of gene expression during early development processes of the tongue sole(Cynoglossus semilaevis)

Differential expression of genes is crucial to growth and development of fish. To select the appropriate genes for gene normalization during Cynoglossus semilaevis early developmental process, eight candidate reference genes （ACTB, B2M, EF1A, GADPH, RPL7, TUBA, UBCE and 18S） were tested for their adequacy by using quantitative real-time PCR. The results showed that the expression of all the examined genes exhibited tissue dependent variations in the mature C. semilaevis. EFIA was listed as the most stable reference among the 14 tissues by RefFinder. Furthermore, the recommended comprehensive ranking of the stability determined by RefFinder showed that 18S was the most stable gene during the early developmental stages （from oosphere to 90 days old） in this study. However, when divided the Ct value data of the above mentioned early developmental stages into two separate periods （embryo and post-hatching periods）, TUBA and 18S represented the most stable references of these two developmental periods, respectively. Consequently, the reference gene should be carefully and accurately chosen even for studies of the same species at various developmental processes. The relevant data may help in selecting appropriate reference genes for mRNA expression analysis, and is of great value in the studies of fish growth and development.

Effects of temperature and irradiance on early development of Chondrus ocellatus Holm (Gigartinaceae,Rhodophyta)

Chondrus is a type of commercially produced red seaweed that widely used for food and carrageen extraction. Although the natural life history of the alga had been well understood, the factors influencing development of the tetraspore and carpospore remain poorly understood. In the perspective of seedling resources, the regulation of early development is crucial for the seedlillg nursing; therefore, it is necessary to understand the physiological influences during its early development. In this study, we studied the effects of temperature and irradiance on the early development of Chondrus ocellatus Holm under laboratory conditions. The released tetraspores and carpospores were cultivated at different temperatures （10-28℃） and irradiances （10, 60 μmol photons m^-2s^-1） with a photoperiod of 12L： 12D. The results indicate that both tetraspores and carpospores are tolerant to temperatures of 10-25℃, and have the highest relative growth rate at 20℃. Irradiance variances influenced the growth of the discoid crusts, and the influence was more significant with increasing temperature; 60 μmol photons m^-2s^-1 was more suitable than 10 μmol photons m^-2s^-1. The optimum temperature and irradiance for the development of seedlings was 20℃ and 60 μmol photons m^-2s^-1, respectively.

Early development of Grateloupia turuturu (Halymeniaceae, Rhodophyta)

Grateloupia turuturu is a commercial red alga with potential value in nutraceuticals and pharmaceuticals. To supplement information on its life history and verify whether carpospores can be used for seedling culture, early development of G. turuturu was investigated under culture conditions （27~C, 10-13 ~mol/（mZ.s） in irradiance, photoperiod 10：14 h L：D）. Three physiological stages were recognized by continuous microscopic observation： division stage, discoid crust stage, and juvenile seedling stage. At the beginning of the division stage, the carpospores developed germ tubes into which the carpospore protoplasm was evacuated, and then the carpospore protoplasm in the germ tubes began to divide continuously until discoid crusts formed. Finally, upright thalli appeared on the discoid crusts and developed into juvenile seedlings. It took about 60 days for carpospores to develop into juvenile seedlings. The growth parameters, including germination rate for carpospores and discoid crust diameter, were recorded. These results contribute more information on the life cycle, and at the same time are of great significance in the scaling-up of artificial seedling cultures of G. turuturu.

Effects of seawater acidification on the early development of sea urchin Glyptocidaris crenularis

In this study, we evaluated the effects of CO_2-induced seawater acidification on fertilization, embryogenesis and early larval development in the sea urchin Glyptocidaris crenularis, that inhabits subtidal coastal areas in northern China. The range in seawater p H used in experiments was based on the projections of the Intergovernmental Panel on Climate Change(IPCC), to the year 2100. A natural seawater treatment(p H_(nbs) =7.98±0.03) and three laboratory-controlled acidified treatments(OA_1, ΔpH_(nbs) =-0.3 units; OA_2, ΔpH_(nbs) =-0.4 units; OA_3, ΔpH_(nbs) =-0.5 units) were used in experiments. Results show that:(1) there was a negative effect of seawater acidification on fertilization and on the percentage of abnormal fertilized eggs;(2) the size of early cleavage stage embryos decreased in a dose-dependent manner with decreasing p H;(3) both the hatching rate of blastulae and the survival rate of four-armed pluteus larvae decreased as pH declined;(4) larval abnormalities including asymmetrical development, changes in the length of skeletal elements, and corroded spicules were observed in all seawater acidified-treatments compared with the control. These data indicate that seawater acidification has a negative impact on the early development of G. crenularis, and supports the hypothesis that the response of echinoderms to ocean acidification(OA) varies among species. Further research is required to clarify the specific cellular mechanisms involved.

The early life immune dynamics and cellular drivers at single-cell resolution in lamb forestomachs and abomasum

Background Four-chambered stomach including the forestomachs(rumen,reticulum,and omasum)and abomasum allows ruminants convert plant fiber into high-quality animal products.The early development of this four-chambered stomach is crucial for the health and well-being of young ruminants,especially the immune development.However,the dynamics of immune development are poorly understood.Results We investigated the early gene expression patterns across the four-chambered stomach in Hu sheep,at 5,10,15,and 25 days of age.We found that forestomachs share similar gene expression patterns,all four stomachs underwent widespread activation of both innate and adaptive immune responses from d 5 to 25,whereas the metabolic function were significantly downregulated with age.We constructed a cell landscape of the four-chambered stomach using single-cell sequencing.Integrating transcriptomic and single-cell transcriptomic analyses revealed that the immune-associated module hub genes were highly expressed in T cells,monocytes and macrophages,as well as the defense-associated module hub genes were highly expressed in endothelial cells in the four-stomach tissues.Moreover,the non-immune cells such as epithelial cells play key roles in immune maturation.Cell communication analysis predicted that in addition to immune cells,non-immune cells recruit immune cells through macrophage migration inhibitory factor signaling in the forestomachs.Conclusions Our results demonstrate that the immune and defense responses of four stomachs are quickly developing with age in lamb's early life.We also identified the gene expression patterns and functional cells associated with immune development.Additionally,we identified some key receptors and signaling involved in immune regulation.These results help to understand the early life immune development at single-cell resolution,which has implications to develop nutritional manipulation and health management strategies based on specific targets including key receptors and signaling pathways.

Early development of Chondrus ocellatus Holm(Gigartinaceae,Rhodophyta)

Chondrus is an economically important red algae widely used for food and biochemical purpose.It early development is crucial for the culture and seedling propagation.We chose tetraspores and carpospores of Chondrus ocellatus as examples for experiment of the culture,induction and release in laboratory condition,aiming to understand early development of C.ocellatus and to apply in seedling production.Mature C.ocellatus were collected in Qingdao,China,from Nov.to Dec.2004.After the gametophyte and tetrasporophyte were brushed and washed with sterilized seawater,the algal materials were treated in 1.5%KI for 20 min,then were dried for lh to stimulate the releasing of spores.After the spores released overnight,it were cultured in PES medium,incubated at 18℃,10±2μmol/(m^(2).s^(1))in 12:12h(light:dark).The observation and recording under microscope were carried out.Continuous observation of the early development showed that both tetraspore and carpospore are similar to each other.In general,three stages of the early development were shown being division,discoid crust and seedling stages.To the division stage,the most obvious feature was the increasing of cell number;during the discoid crust stage,the discoid crust had a three-dimensional axis,and it began to differentiate into two types of cells:the basal cells and the apical cells;and to the seedling stage,several protuberances-like appeared on the discoid crusts and formed juvenile seedlings.Carpospores and tetraspores exhibited a similar development process that included division stage,discoid crust stage and seedling stage.

Early Growth and Development of Boer Goats from Embryo Transplant

[ Objective] To study the growth-development of Boer goats from embryo transplant. [ Method] With Boer goats from embryo transplant as the tested animals and natural breeding Boer goats born in the same period as CK, the weight of Boer goats at birth and at the age of 1,3 and 6 months as well as the body size at the age of 3 and 6 months were investigated in this study, while their health conditions were also observed and recorded. [ Result] Under the normal feeding conditions, Boer goats from embryo transplant developed well at early stage, and their meat-using body type were also obvious. The average birth weight of bucks was （4.25±0.95） kg, and that of does was （3.74±0.10） kg. The average weight of bucks at the age of 6 months was （31.90 ±0.74） kg and that of was （25.90 ±0.67） kg. The daily gains of bucks and ewes from birth to 6 months of age were 153.64 and 123.11 g respectively, while their body length, body height and chest circumference increased obviously, and there was no significant difference in body weight or body size between them and natural breeding goats. [ Condusioa] The study lays a foundation for further studies on the breedinq and utilization of Boer noats from embryo transplant at early staae.

Formation and early development of tetraspores of Polysiphonia urceolata (Rhodomelaceae,Rhodophyta)

Polysiphonia urceolata is one type of potential commercial red seaweeds used for breeding and cultivation, because of its significant biochemical and biomedical application. However, the information of breeding and seedling incubation for cultivation is limited, especially the early development. In this study, tetrasporohyte and gametophyte of P. urceolata were taken as the study materials in Huiquan Bay, Qingdao, China. The cleaned and sterilized tetrasporophytes and gametophytes were pre-cultured in sterilized seawater, then nurtured at 18℃, 25 μmol photons m^-2 s^-1 in 12：12 h （light：dark） photoperiod. Continuous observation under microscope showed that the early development consists of bipolar division stage and seedling stage. In the division stage, tetraspores germinate into bipolar sporelings that further differentiate into a colorless rhizoidal portion and a lightly pigmented upright shoot. The lightly pigmented rhizoidal cell develops to a rhizoid and the larger pigmented cell transforms to an erect axis. In the seedling stage, several quasi-protuberances appear on the erect axis and form juvenile seedlings. The results demonstrate the culture of P. urceolata from tetraspores under laboratory conditions.

New phenomenon in early development of sporelings in Gracilaria asiatica Chang et Xia(Gracilariaceae,Rhodophyta)

Study on the early development of sporelings from carpospores of Gracilaria asiatica Chang et Xia was conducted indoors under controlled culture conditions. Besides normal development of sporelings, a new developmental phenomenon of filamentous frond was observed. It was composed of one or two rows of cells, and took place from the outmost brim of the basal disc. During the early disc stage of germinated carpospores, one or two filamentous fronds formed on about 10% basal discs. Simul-taneously, young fronds began to arch slightly from the centers of single and coalescent discs; lately more filamentous fronds up to 80% appeared on the brims of basal discs. Meanwhile one or more upright fronds protuberated on the basal discs. Generally, filamentous fronds exhibited in self-existence or co-existence forms with normal young sporelings on the same basal disc, and single cell detached from filamentous fronds developed into a new filamentous frond. This new phenomenon exhibited a unique differentiation pathway during the early development of G. asiatica, which would be potential for the ap-plication in artificial sporelings nursery.

Early development of peer dominance relationships in a captive group of Japanese macaques Macaca fuscata

We studied early development of peer dominance relationships in a captive group of Japanese macaques Macaca fuscata fuscata at the Primate Research Institute of Kyoto University. This study aims to give detailed descriptions on characteristic patterns of maternal rank acquisition from infant to juvenile. Focal subjects were 22 young monkeys belonging to three cohorts born in 2002, 2003 and 2005. Data were collected with a total 2130 sessions of 30-minute continuous recording of focal subjects combined with all occurrence-sampling methods. The onset of aggressive behavior varied per cohort and was delayed in cohorts with fewer close-aged associates. More than 60% of dyadic combinations in agonistic interactions between peers were unidirectional throughout the study period. Although some bidirectional interactions could have involved unstable relationships between particular individuals, most of the bidirectional interactions included a few continuous series of alternating one-sided interactions. A linear order could be found among peers from the first appearance of aggressive behavior, and nearly 90% of those dyads were concordant with that of their mother＇s rank order. Young males were responsible for most of the dominance relations that would not be predicted based on their mother＇s rank. These results suggest that infant monkeys may recognize their own social status relative to their opponent＇s before onset of aggressive behavior and adjust themselves into the matrilineal rank system accordingly.

Early Childhood Development (0 - 6 Years Old) from Healthy to Pathologic: A Review of the Literature

Early childhood development involves an appropriate global intervention concerning the different areas of development such as: physical, cognitive, language and socio-emotional [1]. Especially during the first six years of life in an adequate environment rich in exchange and interaction. We will present in this article a review of the literature concerning normal early childhood development, focus firstly in normal development’s steps, the importance of first experiences and first aid with a stable and caring attachment figure. second, we will describe the various developmental disorders, occurring during this age group which extends from birth to 6 years and based on the DSM5 classification, namely that developmental delay may concern only one aspect of development (e.g. language delay or motor delay specifically) or concern the different aspects of development (overall development delay). The dynamics of development is also important to clarify because schematically we contrast the pathologies fixed to progressive pathologies (where we find the concepts of stagnation or regression in the development of the child). We will discuss in the third chapter, the interest of early detection as well as the multiple clinical and psychometric diagnostic tools, which aim to detect any delay or disorder in order to initiate appropriate care and minimize the long-term consequences.

A strength model for cement-stabilized mud subjected to various curing temperatures and its early-stage quality control

The influence of curing temperature on the strength development of cement-stabilized mud has been well documented in terms of strength-increase rate and ultimate strength.However,the strength development model is not mature for the extremely early stages.In addition,there is a lack of studies on quality control methods based on early-stage strength development.This paper presents a strength model for cement-stabilized mud to address these gaps,considering various curing temperatures and early-stage behaviors.In this study,a series of laboratory experiments was conducted on two types of muds treated with Portland blast furnace cement and ordinary Portland cement under four different temperatures.The results indicate that elevated temperatures expedite strength development and lead to higher long-term strength.The proposed model,which combines a three-step conversion process and a hyperbolic model at the reference temperature,enables accurate estimate of the strength development for cement-treated mud with any proportions cured under various temperatures.With this model,a practical early quality control method is introduced for applying cement-stabilized mud in field projects.The back-analysis parameters obtained from a 36-h investigation at temperature of 60C demonstrated a sufficient accuracy in predicting strength levels in practical applications.

Keratin expression during early embryonic development of Bufo bufo gargarizans

Three anti-keratin MAbs were used to identifykeratins expressed in early embryos of Bufo bufogargarizans.MAb AF5 recognized three polypeptides ofkeratin in oocytes,fertilized eggs,up to neurula withMr of 68,65 and 60Kd respectively.At tailbud stage,three other keratins(62,58 and 54Kd)began to expressand could be detected by AF5.MAbs D10 and K12 gavedifferent results,both of them could identify four keratin-like molecules with unusual molecular weights(Mr 98,95,30 and 27 Kd).Moreover,D10 could also detect a 54 Kdkeratin in neurula and tailbud stage embryos,while K12could reveal,beside 54Kd keratin,other four more kera-tins(68,65,62 and 60 Kd).The possible interpretation ofthese results and their implications are discussed.
