Background:Although fear of cancer recurrence(FCR)is the most important factor affecting the life quality of young breast cancer patients,and it may be affected by the patient’s personality,marital relationship and communication,there is a lack of research on the relationship between adult attachment,self-disclosure and FCR in patients.This study investigated the current situation of FCR in young breast cancer patients,its correlation with adult attachment and self-disclosure and its influencing factors,in order to predict the impact of adult attachment and self-disclosure of patients to spouse on FCR.Methods:A survey was conducted on 126 breast cancer patients at our hospital using the General Information Questionnaire(GIQ),Fear of Progression Questionnaire-Short Form(FoP-Q-SF),Experiences in Close Relationships inventory(ECR),and Distress Disclosure Index(DDI).The study analyzed the status of FCR among young breast cancer patients and its correlation with adult attachment and self-disclosure,along with its influencing factors.Results:Among the 126 young breast cancer patients,50 had a FoP-Q-SF score<34(normal group),while 76 had a FoP-Q-SF score≥34(FCR positive group),with an FCR incidence rate of 60.32%.Univariate analysis showed statistically significant differences between the two groups in terms of FoP-Q-SF score,ECR score,attachment anxiety score,attachment avoidance score,DDI score,age,educational level,employment status,per capita monthly income,and treatment method(p<0.05).Correlation analysis revealed that FoP-Q-SF scores were positively correlated with attachment anxiety score,attachment avoidance score,ECR scores and negatively correlated with DDI scores(p<0.05).Linear regression analysis indicated that age,per capita monthly income,treatment method,attachment anxiety,attachment avoidance and self-disclosure level were negative predictors of FoP-Q-SF scores in young breast cancer patients(p<0.05).Conclusion:The incidence rate of FCR among young breast cancer patients is high.There is a positive correlation between adult attachment and the level of FCR,and a negative correlation between the level of self-disclosure and FCR.Patients with lower per capita monthly income,more complex treatment methods,higher level of attachment anxiety,higher level of attachment avoidance and lower DDI scores had higher FoP-Q-SF scores. 展开更多

BACKGROUND Spinal meningiomas(SMs)are common benign tumors that are typically treated with surgical resection.The choice of surgical approach may vary depending on the location of dural attachment of the SM,with a posterior approach being the traditional preference.However,there is limited research available on the impact of dural attachment location on outcomes following posterior approach for SM resection.The average age of the included 34 patients’(10 males and 24 females)age was 62.09 years.Mean follow-up duration was 22.65 months.The location of SM was the thoracic spine in 32 cases,with only 2 in the cervical spine.On average,intraoperative blood loss was 520.59 mL,and operating time was 176.76 minutes.Thirty three cases had successful outcomes while only 1 experienced an unexpe-cted outcome.The tumor recurrence rate was 2.9%.After surgery,there were 3 cases of cerebral spinal fluid leakage,1 case of pneumonia,and 1 case of urinary tract infection.Dural attachments were predominantly found dorsal or dorso-lateral(13 cases),followed by ventral or ventrolateral(14 cases),and lateral(7 cases).The outcomes among these subgroups were similar.CONCLUSION The posterior approach for SM resection is safe and effective,yielding comparable surgical and neurological outcomes regardless of the dural attachment location. 展开更多

This article explores the intricate relationship between attachment styles formed during early childhood and the subsequent responses to traumatic events, particularly the death of a parent. Drawing on the theoretical framework of attachment theory and incorporating contemporary research, the paper discusses how parental interactions shape the neural circuitry of infants and children, influencing their ability to form secure or insecure attachments. These attachment styles, in turn, play a critical role in determining the child’s coping mechanisms when faced with trauma. This paper focuses on trying to understand how attachment theory is connected to the reaction to trauma with a highlight on the four major styles of attachments which are secure, anxious, avoidant, and disorganized to mention but a few, and how they influence stress and adversity in children. Attachment theory holds that human beings’ ability to form affectional bonds in infancy determines their patterns of relatedness across the life cycle. The type of attachment that is secure usually supports healthy adaptation and good coping mechanisms regardless of the trauma in the childhood of the child. While secure attachment mostly facilitates favorable trauma-related outcomes, anxious or avoidant attachment can exacerbate or alter the responses. The caregiving system that is avoidant attachment has implications of autonomous self-functioning which has features of suppression of the emotional response and poor search for emotional support during stress. From the principles of developmental psychology and trauma theory, the paper also focuses on the major significance of the child’s early caregivers’ interactions that define the resilience and vulnerability factor. This knowledge is therefore critical in designing specific interventions based on the improvement of coping behaviors and emotional regulatory systems of children who have been exposed to trauma. Finally, we have the synthesis of new knowledge about the role of secure attachment relationships as its fundamental element in shaping adaptive traumatization and psychological development. The article also delves into the physiological processes involved in emotional regulation and the role of cortisol in disrupting attachment. Finally, the implications of these findings for therapeutic interventions and the challenges of addressing prolonged grief and traumatic responses in clinical settings are considered. 展开更多

In order to theoretically study the growth morphology of dihydroxylammonium 5,5’-bistetrazole-1,1’-dio late(TKX-50)crystal in different solvent systems,crystal–solvent models were established,and then molecular dynamics(MD)methods were adopted as a means to simulate particle motion.Modified attachment energy(MAE)model was employed to calculate the growth morphology of TKX-50.The simulation results demonstrate that COMPASS force field and RESP charge are suitable for molecular dynamics simulation of TKX-50.The morphologically dominant growth surfaces of TKX-50 in vacuum are(020),(011),(11–1),(100)and(120),respectively.In water(H_(2)O)and N,N-dimethylformamide(DMF)solvents,the(11–1)face is the largest in the habit face,the growth rate of(020)face becomes faster.With the increase of temperature,the aspect ratios of TKX-50 crystal in DMF solvent increase,and the areas of the(120)faces decrease.In ethylene glycol/H_(2)O mixed solvent system with volume ratio of 1/1,aspect ratio of TKX-50 is relatively small.In formic acid/H_(2)O mixed solvents with different volume ratios(1/4,1/3,1/2,1/1 and 2/1),aspect ratio of TKX-50 is relatively small when volume ratio is 1/2. 展开更多

The implementation of China’s three-child fertility policy has led to a notable increase in multiple-child families.Notably,firstborn children experience a significant transition from being an only child to a non-only child.This transition is associated with problematic behaviors,affecting their social adjustment,sibling relationships,and family harmony.Although several studies have examined the relationship between parent-child attachment and problem behaviors exhibited byfirstborn children during family transitions,thefindings have been inconsistent.Hence,a meta-analytic study was undertaken to elucidate the inconsistencies in this relationship and explore the moderating factors that may contribute to these discrepancies.Using a systematic literature retrieval and screening method,12 effect sizes were derived from the 10 eligible articles,encompassing a sample size of 5319.The meta-analysis demonstrated a low negative association between parent-child secure attachment and problem behaviors exhibited byfirstborn children during family transitions.Furthermore,the present study investigates potential moderator factors,such as children’s age and geographic region,to gain a more nuanced understanding of the relationship.Consequently,the establishment of parent-child attachment relationships has the potential to mitigate problem behaviors observed infirst-born children during family transitions.The implications of thesefindings indicate that parents can nurture secure attachment bonds with their children by demonstrating sensitive responsiveness,employing positive parenting practices,and fostering emotional availability.These efforts contribute to the cultivation of secure internal working models and positive behavioral manifestations withinfirst-born children,which in turn affect their relationships with siblings. 展开更多

Objective:To compare the effect of human chorionic gonadotropin(hCG)-producing peripheral blood mononuclear cells(PBMCs)and PBMCs activated by hCG in vitro and expressions of related immune genes in mouse implantation.Methods:hCG-producing PBMCs(transfected PBMC)and PBMCs activated by hCG in vitro were introduced into isolated mouse endometrial cells,while cell cultures were divided into four groups:the control,PBMC,transfected,and activated PBMC groups.The expression of studied genes(IL-1β,IL-6,Lif,and Vegf)was evaluated and blastocyst attachment on the cocultured cells(isolated endometrial cells and PBMC cells)was monitored in all four groups.Results:Data showed that expression decreased in the PBMC group compared to the treated PBMC(transfected and activated PBMCs)and increased in transfected PBMC compared to the activated PBMC.Attachment and migration of blastocysts were dramatically enhanced in the transfected PBMC group compared to the activated PBMC group(P<0.05).Conclusions:Use of hCG-producing PBMCs(transfected PBMC)has more influence on endometrial receptivity. 展开更多

The bipartite graph structure exists in the connections of many objects in the real world, and the evolving modeling is a good method to describe and understand the generation and evolution within various real complex networks. Previous bipartite models were proposed to mostly explain the principle of attachments, and ignored the diverse growth speed of nodes of sets in different bipartite networks. In this paper, we propose an evolving bipartite network model with adjustable node scale and hybrid attachment mechanisms, which uses different probability parameters to control the scale of two disjoint sets of nodes and the preference strength of hybrid attachment respectively. The results show that the degree distribution of single set in the proposed model follows a shifted power-law distribution when parameter r and s are not equal to 0, or exponential distribution when r or s is equal to 0. Furthermore, we extend the previous model to a semi-bipartite network model, which embeds more user association information into the internal network, so that the model is capable of carrying and revealing more deep information of each user in the network. The simulation results of two models are in good agreement with the empirical data, which verifies that the models have a good performance on real networks from the perspective of degree distribution. We believe these two models are valuable for an explanation of the origin and growth of bipartite systems that truly exist. 展开更多

In this work,a modified polyurethane adhesive(PUA)was prepared to realize a convenient encapsulation strategy for lead sedimentation and attachable perovskite solar cells(A-PSCs).The modified PUA can completely self-heal within 45 min at room temperature with an efficient lead ion-blocking rate of 99.3%.The PUA film can be coated on a metal electrode with slight efficiency improvement from 23.96%to 24.15%.The thermal stability at 65℃and the humidity stability at 55%relative humidity(RH)are superior to the devices encapsulated with polyisobutylene.The PUA film has strong adhesion to the flexible substrate and the initial efficiency of the flexible perovskite module(17.2%)encapsulated by PUA remains 92.6%within 1825 h.These results suggest that PUA encapsulation is universal for rigid and flexible PSCs with enhanced stability and low lead hazards.Moreover,it was found that flexible PSCs can be well attached to various substrates with PUA,providing a facile route for the A-PSCs in various scenarios without additional encapsulation and installation. 展开更多

Particle-bubble interaction during electro-flotation of cassiterite was investigated by determining the recovery of cassiterite and the collision mechanism of cassiterite particle and H2 bubble. Flotation tests at different conditions were conducted in a single bubble flotation cell. The recovery of cassiterite was found to be affected by cassiterite particle and bubble size. A matching range, in which the best recovery can be obtained, was found between particle and bubble size. Collision, attachment, and detachment of the particle-bubble were observed and captured by a high-speed camera. Particle-bubble collision and attachment were analyzed with the use of particle-bubble interaction theory to obtain the experimental results. An attachment model was introduced and verified through the photos captured by the high-speed camera. A bridge role was observed between the bubbles and particles. Particle-bubble interaction was found to be affected by bubble size and particle size, which significantly influenced not only the collision and attachment behavior of the particles and bubbles but also the flotation recovery of fine cassiterite particles. 展开更多

The dissociative electron attachment process for CHCl3 at different electric field have been studied with nitrogen as drift and carrier gas using corona discharge ionization source ion mobility spectrometry (CD-IMS). The corresponding electron attachment rate constants varied from 1.26×10-8 cm3/(molecules s) to 8.24×10-9 cm3/(molecules s) as the electric field changed from 200 V/cm to 500 V/cm. At a fixed electric field in the drift region, the attachment rate constants are also detected at different sample concentration. The ionmolecule reaction rate constants for the further reaction between Cl^- and CHCl3 are also detected, which indicates that the technique maybe becomes a new method to research the rate constants between ions and neural molecules. And the reaction rate constants between Cl- and CHCl3 are the first time detected using CD-IMS. 展开更多

The effect of matrix attachment regions (MARs) on foreign gene expression in transgenic plants was studied, The beta-glucuronidase (GUS) gene (uidA) was flanked by the MARs isolated from the genome of maize to form plant expression vector. The vectors with and without MARs were transferred into tobacco ( Nicotiana tabacum L.) through Agrobacterium-mediated transformation procedure. GUS activity assays indicated that MARs could increase expression level of uidA gene. The mean GUS activity could be increased twofold as compared to that of transformants without MARs, and the highest GUS activity of transformant could reach tenfold. The correspondence between GUS activity and mRNA accumulation was positive and indicated that MARs could improve transcription of foreign gene. 展开更多

Based on the problems caused by many oxygen-containing functional groups and poor floatability on the surface of low rank coal,the characteristics of low rank coal were analyzed systematically by means of scanning electron microscopy(SEM),X-ray diffraction(XRD)and X-Ray photoelectron spectroscopy(XPS)techniques.The bubble-particle induction time was used to determine the characterization of the bubble-particle attachment,and the bubble-particle attachment of low rank coal modified by soaking the coal samples in an acid or alkaline solution was analyzed.The floatability of the modified coal surface was verified by flotation tests.The results show that the particle size of 0.125–0.074 mm of the coal sample exhibited better bubble-particle attachment characteristics.The small bubble,the larger approach velocity of bubble and the larger bubble deformation were more helpful to enhance the bubbleparticle attachment.For an acid solution,the smaller the p H was and the longer the soaking time was,the better the floatability of the coal sample and the higher the combustible material recovery were.The combustible material recovery of low rank coal was increased to 78.79%by soaking the sample in an acid solution of pH=0 for 180 min.On the contrary there was a best concentration for the alkaline solution. 展开更多

Attachment theory suggests that anxious attachment is associated with hypervigilance to threatening social stimuli, and avoidant attachment with avoidance or suppression of processing such stimuli. Twenty-five students viewed angry, fearful and neutral female faces in four visual oddball tasks, and completed the Attachment Style Questionnaire, the Autonomy-Connectedness Scale, and Anxiety and Depression subscales of the Symptom Checklist-90. When the oddballs were angry faces in a background of neutral frequents, we found higher levels of autonomy and secure attachment to be related to larger N100 and smaller P300 amplitudes;higher levels of anxious attachment were, on the contrary, associated with smaller N100 and larger P300 amplitudes. Variation in attachment is related to approaching, or withdrawing from threatening stimuli, and ERP-techniques add to our understanding of how the attachment system actually works. 展开更多

The invasive red alga Grateloupia turuturu Yamada could turn Vibrio parahaemolyticus into nonculturable state in live algal culture.In order to elucidate the mechanism of such an effect,a series of culture experiments were performed in this investigation based on three hypothesized causes,namely bacterial attachment,production of reactive oxygen species (ROS) and the discharge of water soluble secondary metabolic compounds.The results reveal that attachment to the thallus surface of G.turuturu was the major reason for the decrease of V.parahaemolyticus in seawater.Further investigations show that V.parahaemolyticus attachment to the surface of algal thallus in live cultures of seaweeds was a common phenomenon.However,the disappearance of the culturability of V.parahaemolyticus occurred only on the thallus of G.turuturu over 72 h among all six algal species tested.Electron microscopic scanning shows that most of V.parahaemolyticus attached to G.turuturu changed from the initial normal bacilli to coccoid-shape after 72 h.The enclosure experiments by enclosing the algal thallus in tubes demonstrate that the nonculturability of V.parahaemolyticus in the water of live culture of G.turuturu occurred after the physical contact of the V.parahaemolyticus to the alga.The capacity of G.turuturu in affecting the culturability of V.parahaemolyticus was not influenced after inhibition of photosynthesis by treatment of 3(3,4dichlorophenyl)-1 ,1dimethyl urea (DCMU) at non-lethal levels.Production of reactive oxygen species after addition of live culture of bacteria was excluded by on-line analyzing the oxidation of dichlorohydrofluorescein (DCFH) to dichlorofluorescein (DCF) in the presence of peroxidase on a VersaFluor fluorometer. 展开更多

Mean scores and SDs were computed for the outcome and predictor measures. Pearson correlations among the measures were computed. The study hypotheses were tested using analysis of variance(ANOVA) and multiple regression analyses. All analyses were performed using the SPSS-17 software package(SPSS Inc., Chicago, IL, United States).RESULTS: ANOVA showed a significant main effect of the insecure attachment styles on depression symptom severity and life satisfaction scores. The results suggestthat depressive symptoms were more severe(F = 4.13, df = 2.67, P < 0.05) and life satisfaction was poorer(F = 5.69, df = 2.67, P < 0.01) in both anxious-ambivalently and avoidantly attached patients compared with their securely attached counterparts, whereas the two insecure groups did not significantly differ by these variables. The anxious/ambivalent attachment style and depression symptom severity significantly contributed to HRQo L, accounting for 21.4% and 29.7% of the total variance, respectively [R2 = 0.79; Adjusted R2 = 0.77; F(5, 67) = 33.68, P < 0.0001], even after controlling for gender, marital and employment status confounders.CONCLUSION: The results show that the anxious/ambivalent attachment style together with depression symptom severity substantially and independently predict the HRQo L outcome in AJD with depressed mood. 展开更多
