Research on the Association between Fear of Cancer Recurrence in Young Breast Cancer Patients and Adult Attachment and Self-Disclosure

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.

Safety and efficacy of posterior approach for resection of spinal meningioma:Impact of dural attachment location

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.

Attachment Styles and Traumatic Responses: Exploring the Impact of Parental Interaction on Child Development and Coping Mechanisms

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.

Collision and attachment behavior between fine cassiterite particles and H_2 bubbles

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.

Electron Attachment Studies for CHCl3 Using Ion Mobility Spectrometry

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.

Influence of Matrix Attachment Regions from Maize on Transgene Expression Level in Tobacco

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.

Improving bubble-particle attachment during the flotation of low rank coal by surface modification

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.

Attachment Styles are Related to ERPs Elicited to Angry Faces in an Oddball Paradigm

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.

Nonculturability of the pathogenic Vibrio parahaemolyticus in live culture of Grateloupia turuturu is associated with bacterial attachment to the algal thalli

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.

Contribution of attachment insecurity to health-related quality of life in depressed patients

AIM: To examine the individual contributions of insecure attachment styles and depression symptom severity to health-related quality of life(HRQo L) in patients diagnosed with adjustment disorder(AJD) with depressed mood. METHODS: Participants were 67 patients diagnosed with International Classification of Diseases, Tenth edition AJD with depressed mood, who completed standardised self-report questionnaires measuring study variables. 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.

Zoospores of Undaria pinnatifida:their efficiency to attach under different water velocities and conjugation behavior during attachment

In the invading course of Undaria pinnatifida, zoospore attachment in a dynamically changed subtidal water environment is crucial for the establishment of a potential population in alien waters. Among many abiotic factors that may interfere with the attachment process, water velocity is the most important one. In this investigation, the effect of water velocity on zoospore attachment of U. pinnatifida was investigated in an artificially designed system. It was found that freshly released zoospores that were transported by water flowing at 0 -16 cm/s showed no difficulty in attaching the smooth surface. Zoospore attachment decreased at elevated water flowing rates. At 70 cm/s no spore attachment occurred. Spores that have settled on glass slide for up to 1 h could not be stripped away by flowing water at a rate of 129 cm/s, the same was true of the 20 d old filamentous gametophytes. It was found that more than 70% of free-swimming zoospores tended to settle down adjacent to the settled spores and formed conjugated clusters from two up to a few hundred cells in still culture.

Cyclin B1 is localized to unattached kinetochores and contributes to efficient microtubule attachment and proper chromosome alignment during mitosis

Cyclin B1 is a key regulatory protein controlling cell cycle progression in vertebrates. Cyclin B1 binds CDK1, a cy-clin-dependent kinase catalytic subunit, forming a complex that orchestrates mitosis through phosphorylation of key proteins. Cyclin B1 regulates both the activation of CDK1 and its subcellular localization, which may be critical for substrate selection. Here, we demonstrate that cyclin B1 is concentrated on the outer plate of the kinetochore during prometaphase. This localization requires the cyclin box region of the protein. Cyclin B1 is displaced from individual kinetochores to the spindle poles by microtubule attachment to the kinetochores, and this displacement is dependent on the dynein/dynactin complex. Depletion of cyclin B1 by vector-based siRNA causes inefficient attachment between kinetochores and microtubules, and chromosome alignment defects, and delays the onset of anaphase. We conclude that cyclin B1 accumulates at kinetochores during prometaphase, where it contributes to the correct attachment of mi- crotubules to kinetochores and efficient alignment of the chromosomes, most likely through localized phosphorylation of specific substrates by cyclin B1-CDK1. Cyclin B1 is then transported from each kinetochore as microtubule attachment is completed, and this relocalization may redirect the activity of cyclin B1-CDK1 and contribute to inactivation of the spindle assembly checkpoint.

The Role of Internet Pornography Use and Cyber Infidelity in the Associations between Personality, Attachment, and Couple and Sexual Satisfaction

Although adults in romantic relationships currently show more openness to online sexual behaviors [1], these behaviors can nevertheless increase couple conflicts and instability [2]. In the current study, we assess the mediating role of Internet pornography use and cyber infidelity in the relationship between 1) personality and attachment, and 2) couple and sexual satisfaction. A total of 779 participants in couple relationships (average age = 29.9 years) completed a series of online questionnaires. According to their responses, 65% of participants visited an adult site at least once during the six months preceding the study, while 16.3% did so multiple times per week. Path model results showed that Internet pornography use and cyber infidelity were sequential mediators between, on the one hand, personality and attachment, and on the other hand, couple and sexual satisfaction. The discussion highlights the importance of properly documenting the correlates of online sexual behavior to better understand new couple realities and dynamics.

Alleviation for contact stresses in curvic attachments

This paper studied the contact stresses in curvic attachments.The principal purpose of this research is to employ a method of alleviating the fluctuating hoop stresses which can be considered to be a major contribution to fatigue failure in curvic attachments.This method entails novel precision geometry of the contacting flat on curvic which is a tactic to get appropriate arc heights in in-plane direction as well as vary radius in out-of-plane direction.The dimensional finite elements in both directions were analyzed.These analysis results indicated that significant reduction in fluctuating hoop stresses can be achieved by the proposed method,provided that the precision geometry is controlled sufficiently precisely.

Exploring the Association between Adult Attachment Styles in Romantic Relationships, Perceptions of Parents from Childhood and Relationship Satisfaction

Little research has examined how attachment styles in childhood are related to current romantic relationship experiences. The aim of this study was to explore the association between perceptions of childhood experiences with parents, attachment styles in romantic relationships, and relationship satisfaction in a sample of young adults. The sample consisted of 227 participants, 153 of which were university students and the remaining 69 were members of the general population. Of these, 177 (78%) were female and 50 (22%) were male, with an age range of 18 - 39. Participants completed a battery of self-report measures assessing their attachment style in romantic relationships, satisfaction in their current romantic relationship, and an adjective checklist describing their parents and their parent’s relationship with each other. The majority of males had an avoidant-fearful style, while females tended to have an avoidant-fearful or secure style. Findings were that participants’ descriptions of their mother, father, and parental relationship were associated with their attachment style. In terms of a current romantic relationship, those with a secure attachment style were much more likely to be in a relationship whereas those with an avoidant-fearful style were not. Secure participants were more satisfied in their relationships than the insecure styles of attachment. Finally, chi-square tests revealed that there was no association between gender and attachment style. Results were discussed in terms of methodological limitations such as the use of self-report measures;theoretical weaknesses for example the variability in the approaches used in attachment research;and future research, which included the use of longitudinal studies which may offer insight into how early parenting behaviours act as predictors of later relationship functioning.

Integrin-linked kinase in gastric cancer cell attachment,invasion and tumor growth

AIM： To investigate the effects of integrin-linked kinase （ILK） on gastric cancer cells both in vitro and in vivo. METHODS： ILK small interfering RNA （siRNA） was transfected into human gastric cancer BGC-823 cells and ILK expression was monitored by real-time quan- titative polymerase chain reaction, Western blotting analysis and immunocytochemistry. Cell attachment, proliferation, invasion, microfilament dynamics and the secretion of vascular endothelial growth factor （VEGF） were also measured. Gastric cancer cells treated with ILK siRNA were subcutaneously transplanted into nude mice and tumor growth was assessed. RESULTS： Both ILK mRNA and protein levels were significantly down-regulated by ILK siRNA in human gastric cancer cells. This significantly inhibited cell attachment, proliferation and invasion. The knockdown of ILK also disturbed F-actin assembly and reduced VEGF secretion in conditioned medium by 40% （P 〈 0.05）. Four weeks after injection of ILK siRNA-transfected gastric cancer cells into nude mice, tumor volume and weight were significantly reduced compared with that of tumors induced by cells treated with non-silencing siRNA or by untreated cells （P 〈 0.05）. CONCLUSION： Targeting ILK with siRNA suppresses the growth of gastric cancer cells both in v/tro and /n vivo. ILK plays an important role in gastric cancer progression.
