Dialogue Design for a Robot-Based Face-Mirroring Game to Engage Autistic Children with Emotional Expressions
We present design strategies for Human Robot Interaction for school-aged autistic children with limited receptive language. Applying these strategies to the DE-ENIGMA project (large EU project addressing emotion recognition in autistic children) supported development of a new activity for in facial expression imitation whereby the robot imitates the childâs face to encourage the child to notice facial expressions in a play-based game. A usability case study with 15 typically-developing children aged 4â6 at an English-language school in the Netherlands was performed to observe the feasibility of the setup and make design revisions before exposing the robot to autistic children
INTERCONNECTION BETWEEN MIXED-HANDEDNESS, DIGIT RATIOS AND HAND AND FOOT MINOR ANOMALIES IN PREDICTING SCHIZOPHRENIA
Background: According to the neurodevelopmental theory, brain structuring early markers could be seen in different body parts
as minor physical anomalies. Alongside minor physical anomalies, handedness and index to ring finger ratio are brain development
indicators, specifically brain lateralization. Studies are consentient about the association of these findings with schizophrenia,
though there is inconsistency about individual anatomical regions\u27 contribution. We proposed that handedness in combination with
morphological indicators of early brain development could be sensitive and specific in predicting schizophrenia status.
Subjects and methods: Within the list for the assessment of schizophrenia patients and normal controls of the Caucasian race
were seven categorical minor physical anomalies of hand and feet, handedness, and index to ring finger ratio. In this cross-sectional
study the examinees were recruited from January 2012 to December 2015.
Results: Forced-entry binary logistic regression model correctly classified 86.5% of patients and 99.2% of the comparison
subjects with a 92.8% overall accuracy. Mixed-handedness, hyperconvex fingernails, big gap between 1st and 2nd toe, and partial
syndactyly of 2nd and 3rd toe made a significant independent contribution to the patient-control prediction group status. Furthermore,
these items showed a significant correlation with the predictors of the head from the previous study.
Conclusion: Briefly, the limb components, assessed independently of other body regions, proved to be worthy as schizophrenia
predictors
A coordinated DNA damage response promotes adult quiescent neural stem cell activation
Stem and differentiated cells frequently differ in their response to DNA damage, which can determine tissue sensitivity. By exploiting insight into the spatial arrangement of subdomains within the adult neural subventricular zone (SVZ) in vivo, we show distinct responses to ionising radiation (IR) between neural stem and progenitor cells. Further, we reveal different DNA damage responses between neonatal and adult neural stem cells (NSCs). Neural progenitors (transit amplifying cells and neuroblasts) but not NSCs (quiescent and activated) undergo apoptosis after 2 Gy IR. This response is cell type- rather than proliferationdependent and does not appear to be driven by distinctions in DNA damage induction or repair capacity. Moreover, exposure to 2 Gy IR promotes proliferation arrest and differentiation in the adult SVZ. These 3 responses are ataxia telangiectasia mutated (ATM)- dependent and promote quiescent NSC (qNSC) activation, which does not occur in the subdomains that lack progenitors. Neuroblasts arising post-IR derive from activated qNSCs rather than irradiated progenitors, minimising damage compounded by replication or mitosis. We propose that rather than conferring sensitive cell death, apoptosis is a form of rapid cell death that serves to remove damaged progenitors and promote qNSC activation. Significantly, analysis of the neonatal (P5) SVZ reveals that although progenitors remain sensitive to apoptosis, they fail to efficiently arrest proliferation. Consequently, their repopulation occurs rapidly from irradiated progenitors rather than via qNSC activation
Cognitive Performances Are Selectively Enhanced during Chronic Caloric Restriction or Resveratrol Supplementation in a Primate
Effects of an 18-month treatment with a moderate, chronic caloric restriction (CR) or an oral supplementation with resveratrol (RSV), a potential CR mimetic, on cognitive and motor performances were studied in non-human primates, grey mouse lemurs (Microcebus murinus)

Oncolytic Measles Virotherapy and Opposition to Measles Vaccination
Recent measles epidemics in US and European cities where vaccination coverage has declined are providing a harsh reminder for the need to maintain protective levels of immunity across the entire population. Vaccine uptake rates have been declining in large part because of public misinformation regarding a possible association between measles vaccination and autism for which there is no scientific basis. The purpose of this article is to address a new misinformed antivaccination argument-that measles immunity is undesirable because measles virus is protective against cancer. Having worked for many years to develop engineered measles viruses as anticancer therapies, we have concluded (1) that measles is not protective against cancer and (2) that its potential utility as a cancer therapy will be enhanced, not diminished, by prior vaccination
