Emotion dysregulation and intimacy problems are theoretically underpinned correlates of hypersexuality (i.e., uncontrollable sexual urges, fantasies, and behaviors resulting in distress and impairment in different areas of functioning), but the directionality of these associations has not been established, as work in this area has relied on cross-sectional designs. Moreover, although hypersexuality may have significant adverse effects on romantic relationships and approximately half of treatment-seeking individuals are in a relationship, prior studies almost exclusively involved samples of men, regardless of their relationship status. The aim of the present study was to examine the directionality of associations between both partners’ emotion dysregulation, physical (i.e., partnered sexual frequency) and relationship intimacy, and hypersexuality using a longitudinal, dyadic framework. Self-reported data of 267 mixed-sex couples (Mage_men?=?29.9 years, SD?=?8.2; Mage_women?=?27.7 years, SD?=?6.7) at baseline (T1) and six-month follow-up (T2) were analyzed using a crossed-lagged model within an actor–partner interdependence framework. Prior greater emotion dysregulation (T1) in both men and women was associated with their own later greater hypersexuality (T2). Women’s prior greater hypersexuality (T1) was associated with their later lower relationship intimacy (T2). Lower levels of intimacy were not significantly associated with later hypersexuality. No partner effects were found in relation to hypersexuality. Findings suggest that men and women may use sexual behaviors to cope with negative emotions, which could, in turn, lead to hypersexuality. Intimacy problems did not precede hypersexuality, although women’s hypersexuality may reduce their own relationship intimacy over time.

Functional imaging studies in normal humans have shown that the supplementary motor area (SMA) and the primary motor cortex (PMC) are coactivated during various breathing tasks. It is not known whether a direct pathway from the SMA to the diaphragm exists, and if so what properties it has. Using transcranial magnetic stimulation (TMS) a site at the vertex, representing the diaphragm primary motor cortex, has been identified. TMS mapping revealed a second area 3 cm anterior to the vertex overlying the SMA, which had a rapidly conducting pathway to the diaphragm (mean latency 16.7 ± 2.4 ms). In comparison to the vertex, the anterior position was characterized by a higher diaphragm motor threshold, a greater proportional increase in motor-evoked potential (MEP) amplitude with voluntary facilitation and a shorter silent period. Stimulus–response curves did not differ significantly between the vertex and anterior positions. Using paired TMS, we also compared intracortical inhibition/facilitation (ICI/ICF) curves. In comparison to the vertex, the MEP elicited from the anterior position was not inhibited at short interstimulus intervals (1–5 ms) and was more facilitated at long interstimulus intervals (9–20 ms). The patterns of response were identical for the costal and crural diaphragms. We conclude that the two coil positions represent discrete areas that are likely to be the PMC and SMA, with the latter wielding a more excitatory effect on the diaphragm. 相似文献
Chronic hepatitis C virus (HCV) infections compromise natural killer (NK)-cell immunity. Direct-acting antivirals (DAA) effectively eliminate HCV, but the long-term effects on NK cells in cured patients are debated. We conducted a proteomic study on CD56+ NK cells of chronic HCV-infected patients before and 1 year after DAA therapy. Donor-variation was observed in NK-cell proteomes of HCV-infected patients, with 46 dysregulated proteins restored after DAA therapy. However, 30% of the CD56+ NK-cell proteome remained altered 1 year post-therapy, indicating a phenotypic shift with low donor-variation. NK cells from virus-negative cured patients exhibited global regulation of RNA-processing and pathways related to “stimuli response”, “chemokine signaling”, and “cytotoxicity regulation”. Proteomics identified downregulation of vesicle transport components (CD107a, COPI/II complexes) and altered receptor expression profiles, indicating an inhibited NK-cell phenotype. Yet, activated NK cells from HCV patients before and after therapy effectively upregulated IFN-γ and recruited CD107a. Conversely, reduced surface expression levels of Tim-3 and 2B4 were observed before and after therapy. In conclusion, this study reveals long-term effects on the CD56+ NK-cell compartment in convalescent HCV patients 1 year after therapy, with limited abundance of vesicle transport complexes and surface receptors, associated with a responsive NK-cell phenotype. 相似文献
We have previously reported the successful salvage by retinoid acid (RA) of patients with refractory Ki-1 lymphoma. In this study, we have further investigated the effect of all-trans RA on a Ki-1 lymphoma cell line SR786. Similar to the clinical observation, SR786 cells were sensitive to RA treatment (ID50=0.6 mu m). RA-treated SR786 cells were transformed to a more differentiated morphology at 24 h, and subsequently died via apoptosis at 48-72 h. This process was associated with a decreased expression of the proliferation markers and c-myc proto-oncogene. The RA receptor alpha (RAR-alpha), however, showed an immediate enhanced expression at 1/2 h, and followed by an increase of transforming growth factor-beta 1 (TGF-beta 1) gene expression. The apoptosis and increased expression of TGF-beta 1 could be completely blocked;by the addition of cycloheximide given within 12 h of RA treatment. It appears that the RA-induced apoptosis of SR-786 is the result of an RA-induced upregulation of RAR-alpha and a subsequent activation of TGF-beta 1, which in turn leads to a cascade of the suppression of growth-related genes. Our observations strongly support the use of retinoids in Ki-1 lymphoma and invite further studies to test the potential of RA in other specific type T-cell lymphomas. 相似文献
Although consumers have made significant gains in having their voices heard in several areas within mental health, they have made less progress in being able to collaborate with their own treaters in setting treatment goals. On the basis of several years of groundwork by staff at the Connecticut Mental Health Center (CMHC), the Patient Care Committee conducted a needs assessment of providers and consumers to assess both groups' current involvement, interest in, and attitudes toward collaborative treatment planning. The results indicate that providers tend to place much of the responsibility for the difficulties in implementing collaborative treatment planning on consumers. Also, providers tend to underestimate consumers' interest in participating in this process. Implications of these findings for the development of an agency-wide training to enhance the collaborative nature of treatment planning are discussed. 相似文献
Patient-based questionnaires were designed with the aim to identify and rank long-term somatic and psychosocial morbidity in patients with low-stage testicular cancer. A further intention was to compare patients' assessments with experienced doctors' general opinion on quality of life items in cured testicular cancer patients. In pilot study I, 103 tumour-free patients ranked items of physical and psychosocial morbidity after having had various kinds of treatment. Though the ranking procedure appeared to cause some difficulties amongst the patients and subsequently was abandoned, the results indicated considerable differences between the patients' and doctors' evaluations. In pilot study II patients were asked to score the different items. The questionnaire of pilot study II was completed by 107 patients from the Norwegian Radium Hospital (NRH) and 99 relapse-free patients from the Royal Marsden Hospital (RMH) with testicular cancer stage I at least 1 year after infradiaphragmatic radiotherapy (n = 94) or adjuvant chemotherapy (2 cycles,n=26), or patients who had been followed on the surveillance program (n = 86). A total of 93 doctors completed a similar questionnaire, thereby expressing their general opinion on long-term morbidity in comparable testicular cancer patients as seen during routine clinical follow-up. Both the irradiated patients and those on the surveillance program reported slight degrees of Raynaud-like phenomena, neurotoxicity and ototoxicity, most probably representing background morbidity in an age-matched general male population. Doctors tended to underestimate their patients' somatic morbidity, but often overestimated the degree of psychological distress, in particular in patients on the surveillance program. Significant differences between RMH and NRH patients with regard to sexual problems and to leisure time activity may be explained by cultural differences in the two countries. The items presented in the questionnaire used identify important issues for patients cured of testicular cancer which may be used in future multicentre trans-cultural studies assessing these patients' quality of life. This will provide sufficient data for psychometric testing and, together with the findings from patients' free comments, support the final design of a testicular cancer quality of life module. 相似文献
The excitatory conditioning model of contextual sensitisation proposes that the progressive emergence of the locomotion-activating effect of cocaine (or any other stimulant drug) characterising that phenomenon is due to a growing conditioned response (the test context cues) that mimics the unchanging unconditioned response (the drug effect). The present study aimed at verifying whether the relationship between the amplitude of sensitisation and the size of the conditioned response was positive, a direct implication of that view. Sensitisation to the locomotion-activating effect of cocaine (10 mg/kg, s.c.) was firstly generated over 10 daily sessions in 25 mice (strain C57Bl/6J), another lot of 25 mice receiving the same dose of cocaine outside of the testing context. Conditioned locomotion was assessed 24 h later. No significant linear correlations were found between the magnitude of the conditioned response and the magnitude of the sensitised response (delta scores), the rate of sensitisation (individual regression coefficients) or the magnitude of the initial unconditioned response to cocaine (scores in the first session of sensitisation treatment). Accordingly, there was no significant correlation between the magnitude of the initial unconditioned response and the magnitude of the sensitised response or that of the initial unconditioned response. Therefore, the conditioned response is neither necessary nor sufficient for the development of context-dependent sensitisation of the locomotion-activating effect of cocaine, a conclusion that refutes the excitatory conditioning model of that chronic effect. 相似文献
