A common single nucleotide variant in the cytokine receptor-like factor-3 (CRLF3) gene causes neuronal deficits in human and mouse cells.

Single nucleotide variants in the general population are common genomic alterations, where the majority are presumed to be silent polymorphisms without known clinical significance. Using human induced pluripotent stem cell (hiPSC) cerebral organoid modeling of the 1.4 megabase Neurofibromatosis type 1 (NF1) deletion syndrome, we previously discovered that the cytokine receptor-like factor-3 (CRLF3) gene, which is co-deleted with the NF1 gene, functions as a major regulator of neuronal maturation. Moreover, children with NF1 and the CRLF3L389P variant have greater autism burden, suggesting that this gene might be important for neurologic function. To explore the functional consequences of this variant, we generated CRLF3L389P-mutant hiPSC lines and Crlf3L389P-mutant genetically engineered mice. While this variant does not impair protein expression, brain structure, or mouse behavior, CRLF3L389P-mutant human cerebral organoids and mouse brains exhibit impaired neuronal maturation and dendrite formation. In addition, Crlf3L389P-mutant mouse neurons have reduced dendrite lengths and branching, without any axonal deficits. Moreover, Crlf3L389P-mutant mouse hippocampal neurons have decreased firing rates and synaptic current amplitudes relative to wild type controls. Taken together, these findings establish the CRLF3L389P variant as functionally deleterious and suggest that it may be a neurodevelopmental disease modifier.

Dihydroartemisinin alleviates doxorubicin-induced cardiotoxicity and ferroptosis by activating Nrf2 and regulating autophagy.

Although the use of Doxorubicin (Dox) is extensive in the treatment of malignant tumor, the toxic effects of Dox on the heart can cause myocardial injury. Therefore, it is necessary to find an alternative drug to alleviate the Dox-induced cardiotoxicity. Dihydroartemisinin (DHA) is a semisynthetic derivative of artemisinin, which is an active ingredient of Artemisia annua. The study investigates the effects of DHA on doxorubicin-induced cardiotoxicity and ferroptosis, which are related to the activation of Nrf2 and the regulation of autophagy. Different concentrations of DHA were administered by gavage for 4 weeks in mice. H9c2 cells were pretreated with different concentrations of DHA for 24 h in vitro. The mechanism of DHA treatment was explored through echocardiography, biochemical analysis, real-time quantitative PCR, western blotting analysis, ROS/DHE staining, immunohistochemistry, and immunofluorescence. In vivo, DHA markedly relieved Dox-induced cardiac dysfunction, attenuated oxidative stress, alleviated cardiomyocyte ferroptosis, activated Nrf2, promoted autophagy, and improved the function of lysosomes. In vitro, DHA attenuated oxidative stress and cardiomyocyte ferroptosis, activated Nrf2, promoted clearance of autophagosomes, and reduced lysosomal destruction. The changes of ferroptosis and Nrf2 depend on selective degradation of keap1 and recovery of lysosome. We found for the first time that DHA could protect the heart from the toxic effects of Dox-induced cardiotoxicity. In addition, DHA significantly alleviates Dox-induced ferroptosis through the clearance of autophagosomes, including the selective degradation of keap1 and the recovery of lysosomes.

Socioeconomic inequalities in psychosocial well-being among adolescents under the COVID-19 pandemic: a cross-regional comparative analysis in Hong Kong, mainland China, and the Netherlands.

BACKGROUND: Despite evidence on socioeconomic inequalities in psychosocial well-being of adolescents under the COVID-19 pandemic, the explanatory factors and their potential variations across contexts remained understudied. Hence, this cross-regional study compared the extent of inequalities and the mediating pathways across Hong Kong, Mainland China, and the Netherlands. METHODS: Between July 2021 and January 2022, 25 secondary schools from diverse socioeconomic background were purposively sampled from Hong Kong, Zhejiang (Mainland China), and Limburg (the Netherlands). 3595 junior students completed an online survey during class about their socioeconomic position, psychosocial factors, and well-being. Socioeconomic inequalities were assessed by multiple linear regressions using the Slope Index of Inequality (SII), whereas the mediating pathways through learning difficulty, overall worry about COVID-19, impact on family' financial status, resilience, trust in government regarding pandemic management, and adaptation to social distancing were examined by mediation analyses moderated by regions. RESULTS: The adverse psychosocial impact of COVID-19 was stronger in the Netherlands and Hong Kong compared with Mainland China. The greatest extent of socioeconomic inequalities in the change in psychosocial well-being was observed among students in the Netherlands (SII = 0.59 [95% CI = 0.38-0.80]), followed by Hong Kong (SII = 0.37 [0.21-0.52]) and Mainland China (SII = 0.12 [0.00-0.23]). Learning difficulty and resilience were the major mediators in Mainland China and Hong Kong, but to a lesser extent in the Netherlands. CONCLUSION: Socioeconomic inequalities in psychosocial well-being were evident among adolescents under the pandemic, with learning difficulty and resilience of students as the key mediators. Differences in the social contexts should be considered to better understand the variations in inequalities and mediating pathways across regions.

The mediating role of coping strategies between caregiving burden and pre-death grief among Chinese adult-child caregivers of dementia patients.

AIMS: The objective of this study was to examine the relationship between caregiving burden and pre-death grief, with a specific focus on adult-child caregivers in mainland China. Additionally, the study explored whether coping strategies played a mediating role in this correlation. METHODS: A convenience sample of 320 adult-child caregivers of older parents with dementia from Kunming, mainland China, was recruited for the study. Data were collected using the Chinese version of the Marwit-Meuser Caregiver Grief Inventory-Short Form, the Burden Scale for Family Caregivers, and the Ways of Coping Checklist-Revised. RESULTS: Results using linear regression and multiple mediation analysis with Hayes' process model indicated that caregiving burden was positively related to pre-death grief and that active coping mediated the relationship between them. In the female group, active coping partially mediated the association between caregiving burden and pre-death grief, but in the male group, this mediating effect did not exist. CONCLUSION: The study found evidence supporting the link between caregiving burden and pre-death grief among adult-child caregivers of older parents with dementia in mainland China. Furthermore, the caregiving burden prevented the use of active coping, and this decrease in coping increased the perception of pre-death grief. These associations only existed in the female group. IMPLICATIONS: This paper presented the importance of active coping skills in the dementia caregiving process. IMPACT: The findings of this study emphasize the necessity for health practitioners to provide targeted interventions regarding pre-death grief among dementia caregivers and strengthen caregivers' active coping strategies to reduce their pre-death grief. Community-based and personal care support services should be promoted to alleviate their caregiving burden. REPORTING METHOD: We have adhered to the transparent reporting of evaluations with quantitative design statements and the corresponding checklist was followed. PATIENT OR PUBLIC CONTRIBUTION: 'No patient or public involvement'.

Physical exercise, social relationships, and bullying perpetration among school adolescents in China.

Despite contradictory empirical evidence, some suggest that physical exercise is directly related to bullying perpetration. Moreover, the quality of social relationships between adolescents and their parents, peers, and teachers has been proposed as a crucial mediator in the relationship between physical exercise and bullying perpetration. However, few empirical studies have examined such hypotheses. This study used data obtained from the 2014-2015 China Education Panel Survey to examine the direct association between physical exercise and bullying behaviors, as well as the indirect pathways from physical exercise to bullying that are mediated by teenagers' social relationship quality. The results showed no significant direct relationship between physical exercise and bullying behaviors. However, physical exercise has indirect associations with bullying behaviors mediated through social relationship quality, with peer relationships having the strongest mediating effect. The findings indicate that social relationships could mediate the association between physical exercise and bullying behaviors. The study suggests that future prevention and intervention programs should promote adolescents' participation in physical exercise and their social interactions with parents, peers, and teachers to reduce bullying perpetration.

Caring for a parent with dementia: The psychological well-being of adult children.

BACKGROUND: Caregiving for a parent with dementia has both positive and negative influences on psychological well-being of adult children and perceived social support plays an essential role in dementia caregiving process. OBJECTIVES: We examined how the degree of caregiving intensity influences mental health among Chinese adult children then further explored how perceived social support influences the relationship between intensity and psychological well-being. RESEARCH DESIGN AND SETTING: Cross-sectional study in Kunming, mainland China between November 2022 and January 2023. METHODS: We interviewed 320 adult dementia child caregivers. Linear regression and multiple mediation analysis using Hayes' process model were used to assess the relationship between caregiving intensity and psychological well-being, as well as the mediating role of perceived social support. RESULTS: The study found that caregiving intensity was positively associated with depression and negatively associated with life satisfaction. A lack of perceived social support exacerbated these effects for the adult children. Specifically, the caregivers reported higher caregiving intensity when they perceived less family support, which is in turn associated with greater depression and lower life satisfaction among the caregivers. Likewise, those who reported higher caregiving intensity was reported lower friend support, which was in turn associated with greater depression. CONCLUSIONS AND IMPLICATIONS: The findings emphasize the importance of social support, especially family support, and the necessity for health practitioners to provide targeted interventions on both negative and positive aspects of psychological well-being among dementia caregivers and to strengthen caregivers' resources for social support to enhance their well-being. While these findings are cross-sectional, it is logical to assume that those who perceive less support feel that their caregiving responsibilities are more intense, and that intensity could cause the caregiver to withdraw from friends.

The Relationships of Oral Reading Fluency at Word, Sentence, and Passage Levels and Reading Comprehension in Chinese.

This study aims to expand our understanding of the relations of oral reading fluency at word, sentence, and passage levels to reading comprehension in Chinese-speaking secondary school-aged students. In total, 80 participants (46 males and 34 females) ranging from 13 to 15 years old joined this study and were tested on tasks of oral reading fluency at three levels, reading comprehension, and nonverbal IQ. Our results showed a clear relationship from fluency at the level of the word to the sentence and then the passage in oral reading fluency as well as both the direct and indirect importance of word-level oral reading fluency in reading comprehension. Only the indirect effect from word-level oral reading fluency to reading comprehension through passage-level oral reading fluency was significant. Our findings suggest that sentence-level oral reading fluency is the crucial component to reading comprehension in Chinese. Additionally, recognition of the potential value of unique features, such as syntactic awareness and word segment accuracy, that happen at the sentence level should be integrated into instructional activities for reading.

Spin Symmetry Breaking-induced Hubbard Gap Near-Closure in N-coordinated MnO2 for Enhanced Aqueous Zinc-Ion Battery Performance.

Transition metal oxides (TMOs) are promising cathode materials for aqueous zinc ion batteries (ZIBs), however, their performance is hindered by a substantial Hubbard gap, which limits electron transfer and battery cyclability. Addressing this, we introduce a heteroatom coordination approach, using triethanolamine to induce axial N coordination on Mn centers in MnO2, yielding N-coordinated MnO2 (TEAMO). This approach leverages the change of electronegativity disparity between Mn and ligands (O and N) to disrupt spin symmetry and augment spin polarization. This enhancement leads to the closure of the Hubbard gap, primarily driven by the intensified occupancy of the Mn eg orbitals. The resultant TEAMO exhibit a significant increase in storage capacity, reaching 351 mAh g-1 at 0.1 A g-1. Our findings suggest a viable strategy for optimizing the electronic structure of TMO cathodes, enhancing the potential of ZIBs in energy storage technology.

Boryl Radical as a Catalyst in Enabling Intra- and Intermolecular Cascade Radical Cyclization Reactions: Construction of Polycyclic Molecules.

Cascade radical cyclization constitutes an atom- and step-economic route for rapid assembly of polycyclic molecular skeletons. Although an array of redox-active metal catalysts has recently shown robust applications in enabling various catalytic cascade radical processes, the use of free organic radical as the catalyst, which is capable of triggering strategically distinct cascades, has rarely been developed. Here, we disclosed that the benzimidazolium-based N-heterocyclic carbene (NHC)-boryl radical is capable of catalyzing cascade cyclization reactions in both intra- and intermolecular pathways, assembling [5,5] fused bicyclic and [6,6,6] fused tricyclic molecules, respectively. The catalytic reactions start with the chemo- and regioselective addition of the boryl radical catalyst to a tethered alkene or alkyne moiety, followed by either an intramolecular formal [3+2] or an intermolecular [2+2+2] cycloaddition process to construct bicyclo[3.3.0]octane or tetrahydrophenanthridine skeletons, respectively. Eventually, a ß-elimination occurs to release the boryl radical catalyst, completing a catalytic cycle. High to excellent diastereoselectivity is achieved in both catalytic reactions under substrate control.

Ultrastretchable MXene Microsupercapacitors.

Stretchable microsupercapacitors represent emerging miniaturized energy-storage devices for next-generation deformable electronics. Two-dimensional (2D) transition metal carbides (MXenes) are considered attractive electrode materials due to their metallic conductivity, hydrophilic surfaces, and excellent processability. Here, an ultrastretchable microsupercapacitor of interdigitated MXene microelectrodes with crumpled surface textures is created. The microsupercapacitor shows a series of attractive properties including a high specific capacitance of ≈185 mF cm-2 , ultrahigh stretchability up to 800% area strain, and ≈89.7% retention of the initial capacitance after 1000 stretch-relaxation cycles. In addition to static strains, the microsupercapacitor demonstrates robust mechanical properties to retain stable charging-discharging capability under dynamic stretching at different strain rates. A self-powering circuit system utilizes four microsupercapacitor packs to power a light-emitting diode (LED) array, which exhibits stable operations under large tensile strain and skin-attached wearable settings. The developments offer a generic design strategy to enhance the deformability of microsupercapacitors based on 2D nanomaterials.

Potential role of bolus-tracking data of carotid CT angiography for atrial fibrillation prediction.

OBJECTIVES: Atrial fibrillation (AF), a significant cause of ischemic stroke, often goes undetected because of its asymptomatic nature. This study investigated whether the total bolus-tracking time (TTT) and average slope (AS) of a bolus-tracking graph could be used to predict AF. METHODS: This single-center, retrospective study included patients who underwent carotid CTA and a 24-h Holter test. TTT and the average degree of enhancement during bolus-tracking, derived from carotid CTA, were defined as variables of interest. All patients underwent transthoracic echocardiography. Left ventricular diastolic dysfunction and elevated left atrial pressure (LAP) were identified according to the guidelines of the 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging. RESULTS: The final cohort comprised 716 patients, 80 of whom presented with AF. The TTT of the AF group was significantly longer (23.8 ± 5.2 s) than that of the non-AF group (18.7 ± 2.8 s); p < 0.001. The AS of the bolus-tracking graph of the AF group was 0.80 ± 0.24, which was significantly lower than that of the non-AF group 1.38 ± 0.21 (p < 0.001). TTT was associated with a significantly higher risk of AF (odds ratio [OR]: 1.36; p < 0.001) and elevated LAP (OR: 1.46; p < 0.001). In contrast, the AS of the bolus-tracking graph was not significantly associated with either AF or an elevated LAP. CONCLUSION: TTT derived from bolus-tracking carotid CTA is an effective adjuvant tool for detecting AF related to left ventricular diastolic dysfunction and elevated LAP, confirmed using echocardiography. KEY POINTS: • Atrial fibrillation is not only a significant cause of ischemic stroke but is also often masked because of its atypical and asymptomatic features. • The total tracking time, derived from bolus tracking of carotid computed tomography angiography, may be an effective adjuvant tool for detecting undiagnosed atrial fibrillation and elevated left atrial pressure in patients.

Visible-Light-Promoted Cyanoalkylation/Cyclization Cascade Reaction to Assemble Polyheterocycles in Continuous Flow.

This study describes a visible-light-induced cascade reaction for preparing cyanoalkyl-containing polyheterocycles initiated by the photoinduced radical cascade addition of N-arylacrylamide derivatives using cyclic oxime esters as radical sources followed by cyanoalkyl-mediated cyclization. This protocol features outstanding functional group compatibility, providing a variety of desired phenanthridine derivatives in moderate to good yields. Moreover, the application of a microflow technique enhanced these reactions compared with the equivalent batch reaction, significantly reducing reaction times to 10 min.

Syndemic Profiles and Sexual Health Risks Among Sexually Exploited Adolescent Girls in Taiwan: A Latent Class Analysis.

Sexually exploited adolescent girls are disproportionately affected by adverse psychosocial conditions, such as intra-familial child physical and sexual abuse, extra-familial violence and sexual assault, alcohol and drug use, and suicide. Syndemic theory suggests that these adverse psychosocial or syndemic conditions are concentrated and co-occurring in socially marginalized populations, including sexually exploited adolescents, and increase their sexual health risks, including pregnancy, abortion, and the acquisition of sexually transmitted diseases (STDs). To examine clusters of syndemic conditions, latent class analysis (LCA) was conducted to classify 335 sexually exploited girls in Taiwan into subgroups based on their probability of experiencing each syndemic condition. We used syndemic class membership to predict their sexual health outcomes, specifically pregnancy, abortion, and the acquisition of STDs. The results of LCA revealed three classes, which were "low-risk syndemic," "moderate-risk syndemic," and "high-risk syndemic." The risk of acquisition of STDs among sexually exploited girls in the "high-risk syndemic class" and "moderate-risk syndemic class" was 239% and 135% higher, respectively, than the risk of acquisition of STDs among sexually exploited girls in the "low-risk syndemic class." Differences between these three classes in pregnancy and abortion were not significant. Our findings support the syndemic theory that a pattern of syndemic conditions is associated with an increased risk of acquiring STDs. Interventions aimed at reducing the acquisition of STDs among sexually exploited girls in Taiwan should adopt a comprehensive approach to address co-occurring conditions.

Validation of the Thai Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) among young adults.

BACKGROUND: The Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) is a consistent and comprehensive instrument to assess symptoms of specific internet-use disorders including those related to gaming, shopping, pornography use disorder, social networks use and gambling considering criteria in the eleventh revision of the International Classification of Diseases (ICD-11). However, to date, there is little evidence supporting instruments assessing major types of specific internet use disorders in Thailand. The aim of this present study was to assess the psychometric properties of the ACSID-11 among Thai young adults. METHODS: A total of 612 participants were recruited. A confirmatory factor analysis (CFA) examined construct validity of the ACSID-11. Cronbach's α and McDonald's ω were used to assess reliability of the ACSID-11. Pearson correlations examined relationships between ACSID-11 domains and Internet Gaming Disorder Scale-Short Form (IGDS9-SF) scores. RESULTS: The CFA supported validity of the Thai version of the ACSID-11 and a four-factor structure. Specific domains of the Thai ACSID-11, particularly gaming, were positively and significantly correlated with IGDS9-SF scores. CONCLUSIONS: Data indicate that the Thai version of the ACSID-11 is a valid and reliable instrument to assess major types of specific internet use disorders. Additional studies are needed to further examine the validity and reliability of the Thai ACSID-11.

3,4-benzopyrene aggravates myocardial ischemia-reperfusion injury-induced pyroptosis through inhibition of autophagy-dependent NLRP3 degradation.

Polycyclic aromatic hydrocarbons (PAHs) are produced during combustion of organic matter, such as during cigarette smoking, and they exist widely in the environment. Exposure to 3,4-benzo[a]pyrene (BaP), as the most widely studied PAHs, relates to many cardiovascular diseases. However, the underlying mechanism of its involvement remains largely unclear. In this study, we developed a myocardial ischemia-reperfusion (I/R) injury mouse model and an oxygen and glucose deprivation-reoxygenation H9C2 cell model to evaluate the effect of BaP in I/R injury. After BaP exposure, the expression of autophagy-related proteins, the abundance of NLRP3 inflammasomes, and the degree of pyroptosis were measured. Our results show that BaP aggravates myocardial pyroptosis in a autophagy-dependent manner. In addition, we found that BaP activates the p53-BNIP3 pathway via the aryl hydrocarbon receptor to decrease autophagosome clearance. Our findings present new insights into the mechanisms underlying cardiotoxicity and reveal that the p53-BNIP3 pathway, which is involved in autophagy regulation, is a potential therapeutic target for BaP-induced myocardial I/R injury. Because PAHs are omnipresent in daily life, the toxic effects of these harmful substances should not be underestimated.

Associations of Death Anxiety, Inclusion of Smartphone in the Self, and Affiliation Motivation with Smartphone use and Addiction: A Multiple Mediation Study.

This study is the first to apply terror management theory to understanding smartphone addiction by examining the potential indirect effect of death anxiety on smartphone addiction via inclusion of smartphone in the self (i.e., self-expansion), affiliation motivation (the desire to connect with others) for emotional support, and smartphone use. The sample consisted of 1483 Chinese university students between the ages of 18 and 24 (M = 19.14, SD = 1.03) who voluntarily completed an anonymous questionnaire survey. As hypothesized, death anxiety, inclusion of smartphone in the self, affiliation motivation, and smartphone use were directly, positively correlated with smartphone addiction. In addition, death anxiety exerted significant indirect effects via various pathways, including (i) affiliation motivation for emotional support and smartphone use and (ii) inclusion of smartphone in the self and smartphone use. Findings suggest that effective interventions for smartphone addiction should include targeting death anxiety, self-expansion, and affiliation need frustration.

Metal-Organic Framework Supported Copper Photoredox Catalysts for Iminyl Radical-Mediated Reactions.

Visible-light copper photocatalysis has recently emerged as a viable technology for building sustainable synthetic processes. To broaden the applications of phosphine-ligated copper(I) complexes, we describe herein an effective metal-organic framework (MOF)-supported copper(I) photocatalyst for multiple iminyl radical-mediated reactions. Due to site isolation, the heterogenized copper photosensitizer has a significantly higher catalytic activity than its homogeneous counterpart. Using a hydroxamic acid linker to immobilize copper species on MOF supports affords the heterogeneous catalysts with high recyclability. The post-synthetic modification sequence on MOF surfaces allows for the preparation of previously unavailable monomeric copper species. Our findings highlight the potential of using MOF-based heterogeneous catalytic systems to address fundamental challenges in the development of synthetic methodologies and mechanistic investigations of transition-metal photoredox catalysis.

Nanoarchitectonics of g-C3N4 Nanosheets with a AuCu Enhancement Effect for Superior Photo- and Electrochemical Activity.

AuCu alloy nanoparticles (NPs) were embedded in superior thin g-C3N4 nanosheets by a mechanochemical pre-reaction and subsequent thermal polymerization at high temperature. The introduction of AuCu NPs increased conductivity, decreased the band gap, expended light absorption, and improved the separation and transfer efficiencies of photogenerated electrons and holes. Moreover, the uniform distribution of AuCu NPs in g-C3N4 nanosheets is ascribed to the pre-reaction of bulk g-C3N4 and metal salts to create activity cites. The adsorption ability in the visible light region was improved due to the plasma effect of Au. AuCu/g-C3N4 composites (AuCu/CN-1%) with optimized component ratios revealed the highest transient photocurrent responses, the lowest electrochemical impedance arc radius, and the best photocatalytic H2 evolution rate of 930.2 µmol g-1 h-1. These findings exhibited that loading AuCu bimetallic NPs could efficiently offset some disadvantages of g-C3N4 and improve its photocatalytic performances.

Mixed-Linker Isoreticular Zn(II) Metal-Organic Frameworks as Brønsted Acid-Base Bifunctional Catalysts for Knoevenagel Condensation Reactions.

Multicomponent metal-organic frameworks (MOFs) have received an increasing amount of attention due to their potential to produce new topologies, pore metrics, and functionalities compared to MOFs with a single metal cluster and one organic linker. Herein, five isoreticular Zn MOFs were obtained by mixing two types of linear ditopic linkers in a one-pot solvothermal synthesis. Interestingly, in the resulting Zn MOFs a six-connected cyclic trinuclear Zn(II) cluster and an eight-connected linear trinuclear Zn(II) cluster coexist, leading to an uncommon (6,8)-connected network. Catalytic activities toward the solvent-free Knoevenagel reactions were observed for all of these MOFs. Further experimental and computational studies suggest that they are Brønsted acid-base bifunctional catalysts. Through chemical modifications of dicarboxylate ligands, including their aromatic backbones and substituents, we have successfully implemented reticular chemistry for the modulations of pore sizes, surface areas, and catalytic performances in a series of four-component isoreticular MOFs.

Lower prosodic sensitivity in Chinese children with dyslexia and its impact on Chinese reading.

The current study aims to examine prosodic sensitivity in Chinese children with dyslexia and its relation to Chinese reading in children with and without dyslexia. A total of 172 Chinese children from third grade to sixth grade in Taiwanese primary schools were recruited. Thirty (14 male) children were identified as having dyslexia, and the remaining children (N = 142; 67 male) were typically developing children matched with those with dyslexia as carefully as possible with respect to school, grade, and gender. Our results indicated that group differences were found for all three types of prosodic sensitivity. Moderation analyses showed that group had no significant interaction with prosodic sensitivity in predicting Chinese reading, so the participants in the two groups were combined in the following analyses. The results of the stepwise regression analyses showed that only lexical tone awareness could significantly predict Chinese character reading after controlling for phonological awareness, while only intonation awareness could significantly predict reading comprehension after controlling for Chinese character reading. The results provide preliminary evidence on the issue of prosodic sensitivity in Chinese children with dyslexia and its role in Chinese reading, which might provide a novel approach to the teaching of Chinese languages.
