Corpus callosum morphology and relationships to illness phenotypes in individuals with anorexia nervosa.

Anorexia nervosa is an often-severe psychiatric illness characterized by significantly low body weight, fear of gaining weight, and distorted body image. Multiple neuroimaging studies have shown abnormalities in cortical morphology, mostly associated with the starvation state. Investigations of white matter, while more limited in number, have suggested global and regional volume reductions, as well as abnormal diffusivity in multiple regions including the corpus callosum.

Quality of life and broader experiences of those with acoustic neuroma: a mixed methods approach.

Background Acoustic neuromas (ANs) are consistently associated with decreased quality of life (QOL) related to the physical and psychosocial impacts of symptoms experienced from the tumour and its treatment. This study explored patient-reported experiences of ANs in New Zealand, with a focus on the impact on QOL and the provision of information, support and services. Methods A mixed methods approach was taken, conducting an online community survey that included the Penn Acoustic Neuroma Quality of Life Scale (N  = 52).

Exploring the influence of appearance evaluation apprehension: How fear of negative evaluation affects quality of life in people with Vestibular Schwannoma.

People diagnosed with Vestibular Schwannoma (VS) can experience several symptoms both pre and post-treatment. These, alongside the diagnosis experience, can significantly impact their daily life. The present research is a continuation of a larger study aiming to explore the impacts of symptomology and body image/fear of negative evaluation (FNAE) on the quality of life (QOL) for people with VS.

The effect of symptomatology and mental wellbeing on quality of life in people with acoustic neuroma.

Introduction: Acoustic neuroma (AN) research largely employs a medical framework to understand health outcomes. An alternative is to examine quality of life (QOL) outcomes. This study explored whether mental well-being (i.

Complement-mediated immune mechanisms in allergy.

Allergic conditions are associated with canonical and noncanonical activation of the complement system leading to the release of several bioactive mediators with inflammatory and immunoregulatory properties that regulate the immune response in response to allergens during the sensitization and/or the effector phase of allergic diseases. Further, immune sensors of complement and regulator proteins of the cascade impact on the development of allergies. These bioactive mediators comprise the small and large cleavage fragments of C3 and C5.

Alternative translation and retrotranslocation of cytosolic C3 that detects cytoinvasive bacteria.

Complement C3 was originally regarded as a serum effector protein, although recent data has emerged suggesting that intracellular C3 can also regulate basic cellular processes. Despite the growing interest in intracellular C3 functions, the mechanism behind its generation has not been demonstrated. In this study we show that C3 can be expressed from an alternative translational start site, resulting in C3 lacking the signal peptide, which is therefore translated in the cytosol.

Interaction of Serum-Derived and Internalized C3 With DNA in Human B Cells-A Potential Involvement in Regulation of Gene Transcription.

Beside its classical role as a serum effector system of innate immunity, evidence is accumulating that complement has an intracellular repertoire of components that provides not only immune defense, but also functions to maintain cellular homeostasis. While complement proteins, mainly the central component C3, have been detected in B cells, their exact function and source remain largely unexplored. In this study, we investigated the expression and origin of intracellular C3 in human B cells together with its role in B cell homeostasis.
