Foxl2 is required for the initiation of the female pathway in a temperature-dependent sex determination system in Trachemys scripta.

KDM6B-mediated epigenetic modification of the testicular regulator Dmrt1 has previously been identified as the primary switch of the male pathway in a temperature-dependent sex-determination (TSD) system; however, the molecular network of the female pathway has not yet been established. Here, we have functionally characterized for the first time an upstream regulator of the female pathway, the forkhead transcription factor FOXL2, in Trachemys scripta, a turtle species with a TSD system. FOXL2 exhibited temperature-dependent female-specific expression patterns before the onset of gonadal differentiation and was preferentially localized in ovarian somatic cells. Foxl2 responded rapidly to temperature shifts and estrogen. Importantly, forced expression of Foxl2 at the male-producing temperature led to male-to-female sex reversal, as evidenced by the formation of an ovary-like structure, and upregulation of the ovarian regulators Cyp19a1 and R-spondin1. Additionally, knockdown of Foxl2 caused masculinization at the female-producing temperature, which was confirmed by loss of the female phenotype, development of seminiferous tubules, and elevated expression of Dmrt1 and Sox9. Collectively, we demonstrate that Foxl2 expression is necessary and sufficient to drive ovarian determination in T. scripta, suggesting a crucial role of Foxl2 in female sex determination in the TSD system.

Molecular cloning, characterization and expression analysis of the Chinese soft-shelled turtle (Pelodiscus sinensis) chemokine CXCL11.

Chemokines are small, secreted proteins with chemoattractive properties, which play an important role in the recruitment and activation of immune cells. CXCL11 is a CXC chemokine specific for the CXCR3 receptors, which has been shown to mediate the generation of Th1-type immune responses and have bactericidal effects similar to defensins. Herein, we cloned the full-length cDNA of Chinese soft-shelled turtle (Pelodiscus sinensis) CXCL11, designated as PsCXCL11, which consist of an open reading frame (ORF) of 282 bp encoding 93 amino acids, with estimated molecular weight of 10.055 kDa and isoelectric point of 10.37. The deduced PsCXCL11 sequence had a signal peptide, a highly conserved family-specific small cytokine (SCY) domain, one putative N-glycosylation site and ten potential phosphorylation sites. Phylogenetic analysis showed a close relationship between P. sinensis and Chelydra Serpentina CXCL11. P. sinensis CXCL11 basal expression levels were higher in heart, kidney and spleen than in other organs of health turtles. Infections of Aeromonas hydrophila and Staphylococcus aureus led to significant upregulation of P. sinensis CXCL11 in the blood, while significant upregulation of PsCXCL11 were observed in liver and spleen after infection of A. hydrophila, but not S. aureus. PsCXCL11 recombinant protein with His-tag was successfully expressed by an auto-inducible expression system, and purified by Ni-NTA affinity chromatography. These findings laid a solid foundation for further research towards development of the Chinese soft-shelled turtle as a model for the role of CXCL11 in regulating inflammatory responses to stimulation by invading pathogens.

Fucoxanthin Induces Ferroptosis in Cancer Cells via Downregulation of the Nrf2/HO-1/GPX4 Pathway.

This study investigated the mechanism by which fucoxanthin acts as a novel ferroptosis inducer to inhibit tongue cancer. The MTT assay was used to detect the inhibitory effects of fucoxanthin on SCC-25 human tongue squamous carcinoma cells. The levels of reactive oxygen species (ROS), mitochondrial membrane potential (MMP), glutathione (GSH), superoxide dismutase (SOD), malondialdehyde (MDA), and total iron were measured. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blotting were used to assess glutathione peroxidase 4 (GPX4), nuclear factor erythroid 2-related factor 2 (Nrf2), Keap1, solute carrier family 7 member 11 (SLC7A11), transferrin receptor protein 1 (TFR1), p53, and heme oxygenase 1 (HO-1) expression. Molecular docking was performed to validate interactions. Compared with the control group, the activity of fucoxanthin-treated SCC-25 cells significantly decreased in a dose- and time-dependent manner. The levels of MMP, GSH, and SOD significantly decreased in fucoxanthin-treated SCC-25 cells; the levels of ROS, MDA, and total iron significantly increased. mRNA and protein expression levels of Keap1, GPX4, Nrf2, and HO-1 in fucoxanthin-treated cells were significantly decreased, whereas levels of TFR1 and p53 were significantly increased, in a concentration-dependent manner. Molecular docking analysis revealed that binding free energies of fucoxanthin with p53, SLC7A11, GPX4, Nrf2, Keap1, HO-1, and TFR1 were below -5 kcal/mol, primarily based on active site hydrogen bonding. Our findings suggest that fucoxanthin can induce ferroptosis in SCC-25 cells, highlighting its potential as a treatment for tongue cancer.

The forkhead factor Foxl2 participates in the ovarian differentiation of Chinese soft-shelled turtle Pelodiscus sinensis.

The forkhead transcription factor Foxl2 plays a major role in ovarian development and function in mice and fish, and acts as a female sex-determining gene in goat. Its functional role in the sex determination and gonadal differentiation has not yet been investigated in reptiles. Here, we characterized Foxl2 gene in Chinese soft-shelled turtle Pelodiscus sinensis, exhibiting ZZ/ZW sex chromosomes. Foxl2 exhibited a female-specific embryonic expression pattern throughout the critical sex determination periods in P. sinensis. The expression of Foxl2 was induced at early stage in ZZ embryonic gonads that were feminized by estrogen treatment. Most importantly, Foxl2 knockdown in ZW embryos by RNA interference resulted in female-to-male sex reversal, characterized by obvious masculinization of gonads, significant up-regulation of testicular markers Dmrt1 and Sox9, and remarkable down-regulation of ovarian regulator Cyp19a1. Conversely, gain-of-function study showed that overexpression of Foxl2 in ZZ embryos led to largely feminized genetic males, production of Cyp19a1, and a decline in Dmrt1 and Sox9. These findings demonstrate that Foxl2 is both necessary and sufficient to initiate ovarian differentiation in P. sinensis, thereby acting as a key upstream regulator of the female pathway in a reptilian species.

SOX8 is essential for male sexual differentiation in the Chinese soft-shelled turtle Pelodiscus sinensis‡.

SOX8, which belongs to SOXE transcription factor subfamily together with SOX9, participates in sex differentiation and testicular development by enhancing the function of SOX9 in mammals. However, the functional role of SOX8 in sex differentiation has not yet been identified in any non-mammalian vertebrates. Here, we found in the Chinese soft-shelled turtle Pelodiscus sinensis that SOX8 exhibited male-specific higher expression from stage 14 to 18, the critical period of sex determination, prior to the onset of gonadal differentiation. In addition, SOX8 was rapidly down-regulated during male-to-female sex reversal induced by estradiol. Moreover, knockdown of SOX8 led to complete feminization of ZZ P. sinensis, determined by gonadal morphology and distribution of germ cells, as well as the down-regulation of testicular marker DMRT1 and the up-regulation of ovarian regulator FOXL2. In conclusion, this study provides evidence that SOX8 is a key regulator of early male differentiation in P. sinensis, highlighting the significance of the SOX family in reptile sex determination.

Anti-Leukemia Activity of Polysaccharide from Sargassum fusiforme via the PI3K/AKT/BAD Pathway In Vivo and In Vitro.

Studies have shown that Sargassum fusiforme and its extracts are effective herbal treatments for leukemia. We previously found that a polysaccharide from Sargassum fusiforme, SFP 2205, stimulated apoptosis in human erythroleukemia (HEL) cells. However, the structural characterization and antitumoral mechanisms of SFP 2205 remain uncertain. Here, we studied the structural characteristics and anticancer mechanisms of SFP 2205 in HEL cells and a xenograft mouse model. The results demonstrated that SFP 2205, with a molecular weight of 41.85 kDa, consists of mannose, rhamnose, galactose, xylose, glucose, and fucose with monosaccharides composition of 14.2%, 9.4%, 11.8%, 13.7%, 11.0%, and 38.3%, respectively. On animal assays, SFP 2205 significantly inhibited growth of HEL tumor xenografts with no discernible toxicity to normal tissues. Western blotting showed that SFP 2205 therapy improved Bad, Caspase-9, and Caspase-3 protein expression, and ultimately induced HEL tumor apoptosis, indicating mitochondrial pathway involvement. Furthermore, SFP 2205 blocked the PI3K/AKT signaling pathway and 740 Y-P, an activator of the PI3K/AKT pathway, rescued the effects of SFP 2205 on HEL cell proliferation and apoptosis. Overall, SFP 2205 may be a potential functional food additive or adjuvant for preventing or treating leukemia.

The relationship between parental role expectations and sibling jealousy: the mediating effect of first-born children's role cognition.

This study aimed to explore the relationship among parental role expectations, the firstborns' sibling jealousy and their role cognition. A sample of 190 two-family firstborns aged 3-7 years old and their parents from China participated in the study by using experimental methods, questionnaires, and interviews. The results showed: (1) Parental role expectations had a significant positive effect on firstborns' role cognition. (2) The dispositional sibling jealousy of the first-born children was positively correlated with their parents' role expectations. (3) Firstborns' role cognition mediated the relation between parental role expectations and episodic sibling jealousy completely. The first-born children were more inclined to perceive themselves as resource contender and experience the episodic sibling jealousy the greater the parental role expectations.

ESR1 mediates estrogen-induced feminization of genetic male Chinese soft-shelled turtle†.

Exogenous estrogen have shown their feminization abilities during the specific sex differentiation period in several reptiles. However, the specific regulatory mechanism and downstream regulatory genes of estrogen remain elusive. In the present study, 17ß-estradiol (E2), as well as drugs of specific antagonists and/or agonists of estrogen receptors, were employed to figure out the molecular pathway involved in the E2-induced feminization in Chinese soft-shelled turtles, an important aquaculture species in China. E2 treatment led to typical female characteristics in the gonads of ZZ individuals, including thickened outer cortex containing a number of germ cells and degenerated medullary cords, as well as the disappearance of male marker SOX9, and the ectopic expression of ovarian regulator FOXL2 at the embryonic developmental stage 27 and 1 month after hatching. The specific ESR1 antagonist or a combination of three estrogen receptor antagonists could block the sex reversal of ZZ individuals induced by estrogen. In addition, specific activation of ESR1 by agonist also led to the feminization of ZZ gonads, which was similar to the effect of estrogen treatment. Furthermore, transcriptome data showed that the expression level of FOXL2 was significantly upregulated, whereas mRNA levels of DMRT1, SOX9, and AMH were downregulated after estrogen treatment. Taken together, our results indicated that E2 induced the feminization of ZZ Chinese soft-shelled turtles via ESR1, and decrease of male genes DMRT1, SOX9, and AMH and increase of ovarian development regulator FOXL2 might be responsible for the initiation of E2-induced feminization.

Knockdown of R-spondin1 leads to partial sex reversal in genetic female Chinese soft-shelled turtle Pelodiscus sinensis.

Chinese soft-shelled turtle Pelodiscus sinensis is an important aquaculture species in China, the male individual being more valuable in aquaculture because of its larger body size, higher growth rate and less fat compared with females. Understanding the mechanism of ovarian differentiation and development is crucial for the production of mono-sex male offspring. However, little is known about the molecular mechanism underlying turtle ovarian differentiation. Here, we characterized the Rspo1 gene, an upstream regulator of vertebrate female sexual differentiation, in P. sinensis. The messenger RNA of Rspo1 was initially expressed at stage 14, preceding gonadal sex differentiation, and exhibited a sexually dimorphic expression pattern throughout the sex determination and gonadal differentiation periods. Rspo1 was rapidly downregulated during aromatase inhibitor-induced female-to-male sex reversal, which occurred prior to gonadal differentiation. Rspo1 loss of function by RNA interference led to partial female-to-male sex reversal, with masculinized changes in the phenotype of gonads, the distribution of germ cells and the expression of testicular regulators. Collectively, these findings suggest that Rspo1 is necessary for primary female sexual differentiation in P. sinensis. This study demonstrates for the first time the functional role of Rspo1 in reptilian sex determination, and is of fundamental significance for the production of fertile pseudo-female parents and mono-sex male offspring of P.sinensis.

Dmrt1 induces the male pathway in a turtle species with temperature-dependent sex determination.

The molecular mechanism underlying temperature-dependent sex determination (TSD) has been a long-standing mystery; in particular, the thermosensitive genetic triggers for gonadal sex differentiation are largely unknown. Here, we have characterized a conserved DM domain gene, Dmrt1, in the red-eared slider turtle Trachemys scripta (T. scripta), which exhibits TSD. We found that Dmrt1 has a temperature-dependent, sexually dimorphic expression pattern, preceding gonadal sex differentiation, and is capable of responding rapidly to temperature shifts and aromatase inhibitor treatment. Most importantly, loss- and gain-of-function analyses provide solid evidence that Dmrt1 is both necessary and sufficient to initiate male development in T. scripta Furthermore, the DNA methylation dynamics of the Dmrt1 promoter are tightly correlated with temperature and could mediate the impact of temperature on sex determination. Collectively, our findings demonstrate that Dmrt1 is a candidate master male sex-determining gene in this TSD species, consistent with the idea that DM domain genes are conserved during the evolution of sex determination mechanisms.

Enhanced stability of a rumen-derived xylanase using SpyTag/SpyCatcher cyclization.

Microbiota from herbivore rumen is of great interest for mining glycoside hydrolases for lignocellulosic biomass biorefinement. We previously isolated a highly active but poorly thermostable xylanase (LXY) from a rumen fluid fosmid library of Hu sheep, a local high-reproductive species in China. In this study, we used a universal enzyme-engineering strategy called SpyTag/SpyCatcher molecular cyclization to improve LXY stability via isopeptide-bond-mediated ligation. Both linear and cyclized LXY (L- and C-LXY, respectively) shared similar patterns of optimal pH and temperature, pH stability, and kinetic constants (km and Vmax). However, the C-LXY showed enhanced thermostability, ion stability, and resilience to aggregation and freeze-thaw treatment than L-LXY, without compromise of its catalytic efficiency. Circular dichroism and intrinsic and 8-anilino-1-naphthalenesulfonic acid-binding fluorescence analysis indicated that the cyclized enzyme was more capable of maintaining its secondary and tertiary structures than the linear enzyme. Taken together, these results promote the cyclized enzyme for potential applications in the feed, food, paper pulp, and bioenergy industries.

Transcriptome analysis provides insight into the role of the melanin pathway in two differently pigmented strains of the turtle Pelodiscus sinensis.

Pelodiscus sinensis is the most common turtle species raised in East and Southeast Asia. The Japanese strain and the Qingxi black strain are important aquatic breeds of P. sinensis in China with unique characteristics in terms of production performance and appearance, including skin color. In this study, melanin content measure and histological analysis on skin samples of these two strains were carried out to compare their color characteristics. The results showed that Qingxi black turtles clearly have a greater ability to deposit melanin than the Japanese strain especially in the abdomen. Then, de novo transcriptome assembly and differential expression profiling analyses on the ventral skin from the two strains were performed to identify the genes responsible for the differences in skin color using the Illumina RNA-Seq system with three biological replicates. A total of 19,331 annotated unigenes were found by aligning to the reference genome of P. sinensis using TopHat v2.0.12. Differential expression analysis revealed that 670 genes were expressed differently, including 185 upregulated genes and 485 downregulated genes in Qingxi black strain using the DESeq R package (|log2FoldChange| ≥ 1, padj < 0.05). Sixteen differentially expressed genes (DEGs), which were randomly selected, were confirmed by quantitative real-time PCR (qRT-PCR). GO and KEGG analyses revealed four DEGs (agouti signaling protein, frizzled family receptor 1, phospholipase C, and protein kinase C) were related to melanogenesis pathway. Gene expression levels of the four DEGs as well as three genes from the tyrosinase gene family were measured by qRT-PCR. The results indicated that agouti signaling protein, tyrosinase-related protein, and dopachrome tautomerase could be the main genes responsible for the difference in abdominal skin color between the two turtle strains. This study provided valuable information for further analysis of the melanogenesis mechanisms in different varieties of P. sinensis.

Parenting style and young children's executive function mediate the relationship between parenting stress and parenting quality in two-child families.

This study explored the relationship between parenting stress, parenting style, parenting quality, and young children's executive function. In total, 243 firstborns aged 2-9 years old (SD = 3.82) and their parents from two-child families in Beijing participated in the study, which used executive function tasks and parenting questionnaires. The results found that (1) parenting stress negatively predicted parenting quality; (2) parenting style partially mediated the relationship between parenting stress and parenting quality; (3) children's executive function partially mediated the relationship between parenting stress and parenting quality; and (4) the spoiled, democratic, permissive, and authoritarian parenting styles each play a chain mediating role with young children's executive function between parenting stress and parenting quality. Taken together, these findings provide implications for scientific parenting of children with different psychological characteristics (such as executive function) in multiple-child families under Parenting stress.

Induction of Hibernation and Changes in Physiological and Metabolic Indices in Pelodiscus sinensis.

Pelodiscus sinensis (P. sinensis) is a commonly cultivated turtle species with a habit of hibernation. To study the changes in histone expression and methylation of P. sinensis during hibernation induction, a model was established by artificial induction. Physiological and metabolic indices were measured, and the expression and localization of histone (H1, H2A, H2B, H3, and H4) and methylation-related genes (ASH2L, KMT2A, KMT2E, KDM1A, KDM1B, and KDM5A) were measured by quantitative PCR, immunohistochemistry, and Western blot analysis. The results indicated that the metabolism, antioxidation index, and relative expression of histone methyltransferase were significantly decreased (p < 0.05), whereas the activity and expression of histone demethyltransferase were significantly increased (p < 0.05). Although our results showed significant changes in physiological and gene expression after hibernation induction, we could not confirm that P. sinensis entered deep hibernation. Therefore, for the state after cooling-induced hibernation, cold torpor might be a more accurate description. The results indicate that the P. sinensis can enter cold torpor through artificial induction, and the expression of histones may promote gene transcription. Unlike histones expressed under normal conditions, histone methylation may activate gene transcription during hibernation induction. Western blot analysis revealed that the ASH2L and KDM5A proteins were differentially expressed in the testis at different months (p < 0.05), which may perform a role in regulating gene transcription. The immunohistochemical localization of ASH2L and KDM5A in spermatogonia and spermatozoa suggests that ASH2L and KDM5A may perform a role in mitosis and meiosis. In conclusion, this study is the first to report changes in histone-related genes in reptiles, which provides insight for further studies on the physiological metabolism and histone methylation regulation of P. sinensis during the hibernation induction and hibernation period.

Perceived Stress and Mental Health Literacy Among Chinese Preschool Teachers: A Moderated Mediation Model of Anxiety and Career Resilience.

Purpose: Chinese public mental health is currently characterized by a high prevalence of mental ill health and a low consultation rate, due primarily to the nation's low mental health literacy. Previous studies have shown that occupational stress may be a risk factor for mental health literacy. In China, preschool teachers are under high pressure; however, few studies have examined the mechanisms that mediate and moderate the relationship between preschool teachers' feelings of stress and their mental health literacy. Methods: A questionnaire was administered to 2352 preschool teachers to explore the relationship between their stress perceptions and mental health literacy. Results: Preschool teachers' perceived stress was significantly and negatively associated with their mental health literacy, with anxiety playing a partially mediating role. Preschool teachers' career resilience moderated the relationship between perceived stress and anxiety. Perceived stress positively predicted anxiety for teachers with low levels of career resilience; for teachers with high levels of career resilience, perceived stress still positively predicted anxiety, and the higher the level of career resilience, the weaker the positive prediction of stress perception on anxiety. Conclusion: Perceived stress directly predicted mental health literacy among preschool teachers, and also indirectly predicted mental health literacy through the mediating role of anxiety. Career resilience moderated the relationship between stress perception and anxiety. These findings provide new perspectives on the treatment and prevention of preschool teachers' mental ill health.

Study on the pattern of spermatogenesis during the breeding season of the Chinese soft-shelled turtle, Pelodiscus sinensis (Reptilia: Trionychidae).

The Chinese soft-shelled turtle, Pelodiscus sinensis (Reptilia: Trionychidae) is a typical seasonal breeding species and its spermatogenesis pattern is complex. In this study, the process of sperm cell development was studied using histology. The process of sperm cell development may be divided into six stages based on a combination of different cell types in the seminiferous epithelium. A close examination revealed two patterns of sperm cell development in the seminiferous tubules during the breeding season. The first is a normal sperm cell development pattern, in which the process of sperm cell development and maturation are completed in the seminiferous epithelium without round spermatozoa in the lumen. The second is rapid sperm cell development, in which the first batches of round spermatozoa fall off the seminiferous epithelium before they mature, thus beginning a second batch of sperm cell development. The round sperm cells are shed into the lumen and further mature in the seminiferous tubules and epididymis. This rapid sperm cell development process of the Chinese soft-shelled turtle is rare in other vertebrate species and may be an adaptation to cope with seasonal breeding. The results of this study provide insight into the theory of seasonal reproduction in reptiles.

Seasonal spermatogenesis, epididymal storage, and creatine kinase expression in Pelodiscus sinensis.

The soft-shelled turtle, Pelodiscus sinensis, is an important economic aquaculture species. Its reproduction exhibits seasonality; however, there is a lack of systematic studies focused on sperm maturation and epididymal storage. The testes and epididymides of P. sinensis were sampled from March to December. The seasonal reproduction and maturation of the spermatozoa were examined by anatomy, hematoxylin and eosin staining, AB-PAS staining, and immunohistochemistry. Spermatogenesis exhibited obvious seasonality in P. sinensis. It was found that the spermatogenic epithelium was most active during June to September, whereas the diameter of the epididymal tubules was smallest during June to October. As key enzymes of ATP metabolism, creatine kinases were highly expressed in the epididymal tubule epithelium during the breeding season, which may be important for the regulation of sperm maturation. In addition, the epididymal tubule epithelium changed with the season in June to September, the epididymal tubule epithelium proliferated to form villous structures, and secreted a large number of glycoproteins, which may be related to the rapid maturation of sperm during the breeding season. In conclusion, this study provided insights into the spermatogenesis of P. sinensis through histological analysis and enriched our understanding of reproduction in reptiles.

Effects of isorhamnetin on tyrosinase: inhibition kinetics and computational simulation.

We studied the inhibitory effects of isorhamnetin on mushroom tyrosinase by inhibition kinetics and computational simulation. Isorhamnetin reversibly inhibited tyrosinase in a mixed-type manner at Ki=0.235±0.013 mM. Measurements of intrinsic and 1-anilinonaphthalene-8-sulfonate(ANS)-binding fluorescence showed that isorhamnetin did not induce significant changes in the tertiary structure of tyrosinase. To gain insight into the inactivation process, the kinetics were computed via time-interval measurements and continuous substrate reactions. The results indicated that inactivation induced by isorhamnetin was a first-order reaction with biphasic processes. To gain further insight, we simulated docking between tyrosinase and isorhamnetin. Simulation was successful (binding energies for Dock6.3: -32.58 kcal/mol, for AutoDock4.2: -5.66 kcal/mol, and for Fred2.2: -48.86 kcal/mol), suggesting that isorhamnetin interacts with several residues, such as HIS244 and MET280. This strategy of predicting tyrosinase interaction in combination with kinetics based on a flavanone compound might prove useful in screening for potential natural tyrosinase inhibitors.

Cohort Study on the Effect of Psychological Education for Nurses in Psychiatric Department.

With the deepening of the medical and health system, high-quality nursing service with the reform of nursing service model and the provision of holistic nursing care for patients as the core connotation is being comprehensively carried out. With the continuous improvement of medical quality, people's awareness of health has gradually increased. They have put forward higher requirements for medical quality, nursing service quality, and medical care safety. Under the influence of these conditions, the workload and work pressure of clinical nurses continue to increase, and mental health problems become increasingly prominent. According to relevant data, the detection rate of occupational stress among nurses was 100%, and the proportion of nurses who perceived considerable stress was 60.9%, which seriously affected their work efficiency and quality of life. However, the physical and mental health of the frontline nurses working in psychiatric hospitals is not optimistic. This study explored the effects of psychological education among nurses in the department of psychiatry. The results showed that psychological education intervention among nurses in the department of psychiatry could alleviate their professional tiredness, effectively improve their psychological elasticity and happiness index, and thus improve sleep quality and promote their physical and mental health development.

The mediating effect of parenting style on the relationship between first-born children's temperament and psychological adaptation.

Chinese first-born children need to learn how to get along with their siblings after the implementation of the universal two-child policy in 2016. We investigated the relationships between temperament, parenting style, and psychological adjustment among firstborns. The current study employed a questionnaire survey conducted in four regions in China. A total of 524 Chinese two-child families participated in the study; the firstborns were between 3 and 8 years old and their younger siblings were between 1 month and 5 years old. The results indicated that (1) children's temperament subscales were significantly related to parenting style subscales and psychological adaptation. Moreover, the parenting style subscales were significantly related to psychological adaptation, and (2) authoritarian parenting partially mediated the relationship between approach or withdrawal and psychological adjustment.
