Preventing nocebo suggestions through mindfulness meditation

2017

The nocebo effect is a negative outcome resulting from the belief that a desired treatment has either not been received, or that a received treatment is harmful (Hurst, Foad & Beedie, 2015). This effect has been empirically demonstrated to have negative effects on sporting performance and physical endurance. Expectation has been the foremost mechanism in producing the nocebo response and manipulation through verbal suggestions is arguably the most powerful way to generate expectation (Carlino, Benedetti & Pollo, 2014). The purpose of the study was to investigate whether mindfulness practice can counteract the negative expectations given by potentially harmful nocebo effects, in this case ve…

Photoluminescence time decay of surface oxygen deficient centers in un‐doped and Ge‐doped silica

2005

We report a study of the emission decay from the singlet excited state of two fold coordinated Si and Ge centers stabilized on the surface of silica and Ge-doped silica. The PL lifetimes are of the order of nanoseconds and increase on decreasing the temperature. The results suggest that, for the surface centers, the phonon assisted intersystem-crossing process linking the excited states affects the decay rates, is effective down to low temperatures and is distributed because of the inhomogeneity of the defects.

Exploring fast proton transfer events associated with lateral proton diffusion on the surface of membranes

2019

Proton diffusion (PD) across biological membranes is a fundamental process in many biological systems, and much experimental and theoretical effort has been employed for deciphering it. Here, we report on a spectroscopic probe, which can be tightly tethered to the membrane, for following fast (nanosecond) proton transfer events on the surface of membranes. Our probe is composed of a photoacid that serves as our light-induced proton source for the initiation of the PD process. We use our probe to follow PD, and its pH dependence, on the surface of lipid vesicles composed of a zwitterionic headgroup, a negative headgroup, a headgroup that is composed only from the negative phosphate group, or…

Structural characterisation of wood pulp fibres and their nanofibrillated materials for biodegradable composite applications

2011

Introduction: The utilization of wood pulp fibres in composite materials has gained major interest during the last years. One of the major motivations has been the potential of wood pulp fibres and their nanofibrillated derivatives for increasing the mechanical properties of some materials. However, in order to exploit the full potential of wood pulp fibres and cellulose nanofibrils as reinforcement in hydrophilic and hydrophobic matrices, several characteristics of fibres and their interactions with a given matrix need to be understood. With the increasing capabilities of novel microscopy techniques and computerized image analysis, structural analysis is moving forward from visual and subj…

Higher Socioeconomic Status Predicts Less Risk of Depression in Adolescence: Serial Mediating Roles of Social Support and Optimism.

2020

Family socioeconomic status (SES) is known to have a powerful influence on adolescent depression. However, the inner mechanisms underlying this association are unclear. Here, we explore this issue by testing the potential mediating roles of social support (interpersonal resource) and optimism (intrapersonal resource), based on the predictions of the Reserve Capacity Model (RCM). Participants were 652 adolescents (age range: 11-20 years old, Mage =14.55 years, SD = 1.82; 338 boys (51.80%)) from two junior and two senior high schools in Wuhan, China. They completed questionnaires measuring family SES, perceived social support, trait optimism, and depression. Results showed, as predicted, (1) …

Emotional Profile and Intellectual Functioning

2015

Insufficient literature has been produced addressing children with borderline intellectual functioning (BIF) and gifted intellectual functioning (GIF). The goal of this work is to compare levels of self-esteem, depression, anxiety at school, and insecurity among children with BIF and GIF, and a control group of average intellectual functioning (AIF). There were participants of 104 children (fourth grade of primary school). Analyses revealed that children with BIF showed a lower level of self-esteem and higher levels of depression and school anxiety. Moreover, our findings highlight the co-occurrence of school anxiety, depressed mood, and insecurity among the BIF and AIF groups. One of the …

Recalled parental rearing style, self-esteem, and psychopathological symptoms in the general population

2020

The enduring impact of perceived parental behavior on self-esteem as well as anxiety and depression in adults is still unknown. In a large random route sample (age range 18?92), 4,747 subjects were asked to complete questionnaires about recalled parental rearing, selfesteem, anxiety, and depression. Structural equation modeling was used, and the data from the mother and the father version of the FEE (a questionnaire for recalled parental rearing) were analyzed separately. A model proposing that self-esteem mediates the relationship between parental behavior and psychopathological symptoms fits the data rather well (CFI = .95, RMSEA = .05, TLI = .94). Hence, the recalled authoritative parent…

Bcl-xL as a Modulator of Senescence and Aging

2021

Many features of aging result from the incapacity of cells to adapt to stress conditions. When cells are overwhelmed by stress, they can undergo senescence to avoid unrestricted growth of damaged cells. Recent findings have proven that cellular senescence is more than that. A specific grade of senescence promotes embryo development, tissue remodeling and wound healing. However, constant stresses and a weakening immune system can lead to senescence chronicity with aging. The accumulation of senescent cells is directly related to tissue dysfunction and age-related pathologies. Centenarians, the most aged individuals, should accumulate senescent cells and suffer from their deleterious effects,…
