Autism-Associated Gene Expression in Peripheral Leucocytes Commonly Observed between Subjects with Autism and Healthy Women Having Autistic Children

Autism spectrum disorder (ASD) is a severe neuropsychiatric disorder which has complex pathobiology with profound influences of genetic factors in its development. Although the numerous autism susceptible genes were identified, the etiology of autism is not fully explained. Using DNA microarray, we examined gene expression profiling in peripheral blood from 21 individuals in each of the four groups; young adults with ASD, age- and gender-matched healthy subjects (ASD control), healthy mothers having children with ASD (asdMO), and asdMO control. There was no blood relationship between ASD and asdMO. Comparing the ASD group with control, 19 genes were found to be significantly changed. These genes were mainly involved in cell morphology, cellular assembly and organization, and nerve system development and function. In addition, the asdMO group possessed a unique gene expression signature shown as significant alterations of protein synthesis despite of their nonautistic diagnostic status. Moreover, an ASD-associated gene expression signature was commonly observed in both individuals with ASD and asdMO. This unique gene expression profiling detected in peripheral leukocytes from affected subjects with ASD and unaffected mothers having ASD children suggest that a genetic predisposition to ASD may be detectable even in peripheral cells. Altered expression of several autism candidate genes such as FMR-1 and MECP2, could be detected in leukocytes. Taken together, these findings suggest that the ASD-associated genes identified in leukocytes are informative to explore the genetic, epigenetic, and environmental background of ASD and might become potential tools to assess the crucial factors related to the clinical onset of the disorder

Anabolic androgenic steroid use population size estimation: a first stage study utilising a Delphi exercise

Harms associated with anabolic androgenic steroids (AAS) use are well-established and a public health concern. Robust estimates of the numbers using AAS are needed to inform responses, however, in the UK these are lacking. Due to the comparative rarity and associated stigma, general population surveys are problematic and data availability limits the use of indirect approaches. To address this, the Delphi method was used to refine the key parameters needed for indirect estimation from attendances at needle and syringe programmes (NSP) for AAS use. An expert panel (n = 63) was surveyed three times (n = 40, 39, and 37) to refine the parameters needed to generate a likely range from data on NSP attendances. A broad agreement was reached on: regional variations in use; the proportion of men using AAS who only use them orally; the proportion of men who inject AAS using NSP; and the proportion of the AAS population who are women. We conclude that previous general population survey-based estimates of recent AAS use appear implausible, with the likely range indicated by NSP data being up to 10-times higher. AAS use in the UK is more common than previously indicated, but further work is needed to refine population size estimation and characteristics

Problematizing leadership learning facilitation through a trickster archetype: An investigation into power and identity in liminal spaces

This study uses the archetype of a ‘trickster’ to reflect back on, and hence problematize, the role of the educator/facilitator identity in leadership learning. This is based on the view that a trickster is a permanent resident in liminal spaces and that these liminal spaces play an important role in leadership learning. Our approach was based on the reading of the trickster literature alongside reflective conversations on our own experiences of facilitation of leadership learning, development and education. We suggest that paying attention to the trickster tale draws attention to the romanticization of leadership development and its facilitation as based on a response to crisis that leads to a further enhancement of the leader as a hero. Hence, it also offers ways to problematize leadership learning by uncovering the shadow side of facilitation and underlying power relations. We therefore contribute by showing how, as facilitators, we can use the trickster archetype to think more critically, reflectively and reflexively about our role and practices as educators, in particular, the ethical and power-related issues. In our conclusions, we make recommendations for research, theory and practice and invite other facilitators to share with us their trickster tales

Promoting Recruitment using Information Management Efficiently (PRIME): statistical analysis plan for a stepped wedge cluster randomised trial within the REstart or STop Antithrombotics Randomised Trial (RESTART)

BACKGROUND: Promoting Recruitment using Information Management Efficiently (PRIME) is a stepped wedge, cluster randomised trial-within-a-trial of a complex intervention to help sites in the United Kingdom to attain their own target number of participants to recruit to the REstart or STop Antithrombotics Randomised Trial (RESTART, ISRCTN71907627). METHODS: Seventy-two hospital sites had opted into PRIME and were randomly allocated (using a computer-generated block randomisation algorithm, stratified by hospital location) to one of 12 months in which a complex intervention would be delivered. All sites began in the control state. The primary outcome is the total number of patients randomised into RESTART per month per site, which will be analysed in a negative binomial generalised linear mixed model. Secondary outcomes include the proportion of sites using stroke databases to identify potentially eligible patients before PRIME, frequency of using bespoke stroke audit data exports during PRIME, barriers to recruitment in PRIME, barriers to using the bespoke stroke audit data exports, and disadvantages of the bespoke stroke audit exports identified by PRIME sites. PRIME began in September 2015. The last intervention will be delivered in August 2016. Six-month follow-up will be complete in February 2017. This statistical analysis plan was written and submitted for publication before all sites received the PRIME intervention and before outcome data were known. DISCUSSION: Final results of PRIME will be analysed and disseminated in 2017. TRIAL REGISTRATION: Northern Ireland Hub for Trials Methodology Research SWAT repository (SWAT22)

Neurovasculature of high and low tie ligation of the inferior mesenteric artery

PURPOSE: Controversy exists as to whether a high or low tie ligation of the inferior mesenteric artery (IMA) is the preferred technique in surgeries of the left colon and rectum. This study aims to contribute to the discussion as to which is the more beneficial technique by investigating the neurovasculature at each site. METHODS: Ten embalmed cadaveric donors underwent division of the inferior mesenteric artery at the level of the low tie. The artery was subsequently ligated at the root to render a section of tissue for histological analysis of the proximal (high tie), mid and distal (low tie) segments. RESULTS: Ganglia observed in the proximal end of seven specimens in the sample imply that there would be disruption to the innervation in a high tie procedure. CONCLUSION: This study suggests that a high tie should be avoided if the low tie is oncologically viable

Early detection and counselling intervention of asthma symptoms in preschool children: study design of a cluster randomised controlled trial

Background. Prevention of childhood asthma is an important public health objective. This study evaluates the effectiveness of early detection of preschool children with asthma symptoms, followed by a counselling intervention at preventive child health centres. Early detection and counselling is expected to reduce the prevalence of asthma symptoms and improve health-related quality of life at age 6 years. Methods/design. This cluster randomised controlled trial was embedded within the Rotterdam population-based prospective cohort study Generation R in which 7893 children (born between April 2002 and January 2006) participated in the postnatal phase. Sixteen child health centres are involved, randomised into 8 intervention and 8 control centres. Since June 2005, an early detection tool has been applied at age 14, 24, 36 and 45 months at the intervention centres. Children who met the intervention criteria received counselling intervention (personal advice to parents to prevent smoke exposure of the child, and/or referral to the general practitioner or asthma nurse). The primary outcome was asthma diagnosis at age 6 years. Secondary outcomes included frequency and severity of asthma symptoms, health-related quality of life, fractional exhaled nitric oxide and airway resistance at age 6 years. Analysis was according to the intention-to-treat principle. Data collection will be completed end 2011. Discussion. This study among preschool children provides insight into the effectiveness of early detection of asthma symptoms followed by a counselling intervention at preventive child health centres.

The body unbound: ritual scarification and autobiographical forms in Wole Soyinka’s Aké: the years of childhood

The scarification in Aké is invested with major significance apropos Soyinka’s ideas on African subjectivity. Scarification among the Yoruba is one of the rites of passage associated with personal development. Scarification literally and metaphorically “opens” the person up socially and cosmically. Personal formation and self-realization are enabled by the Yoruba social code brought into being by its mythology. The meaning of the scarification incident in Aké is profoundly different. Determined by the form of autobiography which creates a self-constituting subject, the enabling Yoruba sociocultural context is elided. The story of Soyinka’s personal development is allegorical of the story of the development of the modern African subject. For Soyinka, the African subject is a rational subject whose constitution precludes the splitting of the scientific and spiritual which is a consequence of the Cartesian rupture. The African subject should be open to other subjects and the object world. Subjectivity constituted by the autobiographical mode closes off the opening up symbolically signalled by scarification.Web of Scienc

Can weight loss prevent cancer?

We review and update evidence on obesity, weight gain and weight loss in relation to leading cancers since the International Agency for Research on Cancer report of 2002. Emphasis is placed on the time course of disease and implications for weight control to prevent cancer. We conclude that weight loss could prevent a major portion of common cancers

Plastisol Foaming Process. Decomposition of the Foaming Agent, Polymer Behavior in the Corresponding Temperature Range and Resulting Foam Properties

The decomposition of azodicarbonamide, used as foaming agent in PVC - plasticizer (1/1) plastisols was studied by DSC. Nineteen different plasticizers, all belonging to the ester family, two being polymeric (polyadipates), were compared. The temperature of maximum decomposition rate (in anisothermal regime at 5 K min-1 scanning rate), ranges between 434 and 452 K. The heat of decomposition ranges between 8.7 and 12.5 J g -1. Some trends of variation of these parameters appear significant and are discussed in terms of solvent (matrix) and viscosity effects on the decomposition reactions. The shear modulus at 1 Hz frequency was determined at the temperature of maximum rate of foaming agent decomposition, and differs significantly from a sample to another. The foam density was determined at ambient temperature and the volume fraction of bubbles was used as criterion to judge the efficiency of the foaming process. The results reveal the existence of an optimal shear modulus of the order of 2 kPa that corresponds roughly to plasticizer molar masses of the order of 450 ± 50 g mol-1. Heavier plasticizers, especially polymeric ones are too difficult to deform. Lighter plasticizers such as diethyl phthalate (DEP) deform too easily and presumably facilitate bubble collapse
