Abstract. Several decades of research are reviewed, assessing patterns of psychophysiological reactivity in anxiety patients responding to a fear/threat imagery challenge. Findings show substantive differences in these measures within principal diagnostic categories, questioning the reliability and categorical specificity of current diagnostic systems. Following a new research framework (US National Institute of Mental Health [NIMH], Research Domain Criteria [RDoC]; Cuthbert & Insel, 2013 ), dimensional patterns of physiological reactivity are explored in a large sample of anxiety and mood disorder patients. Patients’ responses (e.g., startle reflex, heart rate) during fear/threat imagery varied significantly with higher questionnaire measured “negative affect,” stress history, and overall life dysfunction – bio-marking disorder groups, independent of Diagnostic and Statistical Manuals (DSM). The review concludes with a description of new research, currently underway, exploring brain function indices (structure activation, circuit connectivity) as potential biological classifiers (collectively with the reflex physiology) of anxiety and mood pathology.

Presenting specialty literature background in: organic chemistry, neurology, theology and clinical psychology, in order to conceptualize and bring to the forefront the interdependency between organic chemistry, neurology, psychology and religion in describing the implications of religious thinking in therapeutic compliance is a first objective of the present paper. As such, we addressed the importance of neurotransmitters in the neurophysiology of spiritual interventions. Another specific objective was defined as measuring psychological reactions, components of the moral and religious structure of human personality, with the help of psychophysiological involved factors, in rapport with therapeutic compliance. According to the descriptive statistic of data, we found that those who do not adhere to any religious cult have greater chances of being diagnosed with a disease that necessitates daily treatment and monitoring (the percentage found was 20%), in comparison with those who are part of a religious cult (6.67 %). The estimated non-linear regression model to confirm the interdependency between the medial psychophysiological reactivity to religious stimulus and the medial score obtained in the compliance questionnaire was validated by the values of R = 0.99 and p-value=0.00≈10-10<0.05). As such, we can accept the hypothesis that “there is a statistically significant association between religious thinking and compliance”. On the other hand, the hypothesis “there is a statistically significant association between religious thinking and compliance” was validated, using the t test, only at 40%, as the results of the t test were only considered on significant components of the applied MARS questionnaire. The results given by approaching the two hypotheses through the mixture of psychophysiological and application of the MARS questionnaire consistently highlighted an image of importance of religious thinking in therapeutic compliance. The current study is useful in motivating adherents of any religion, in our study, the Christian belief, to improve their compliance. Keywords: oxcytocin, vassopressin, MARS scale, therapeutic compliance, religious experience

Archaea are best known in their capacities as extremophiles, i.e. micro-organisms able to thrive in some of the most drastic environments on Earth. The protein-based surface layer that envelopes many archaeal strains must thus correctly assemble and maintain its structural integrity in the face of the physical challenges associated with, for instance, life in high salinity, at elevated temperatures or in acidic surroundings. Study of archaeal surface-layer (glyco)proteins has thus offered insight into the strategies employed by these proteins to survive direct contact with extreme environments, yet has also served to elucidate other aspects of archaeal protein biosynthesis, including glycosylation, lipid modification and protein export. In this mini-review, recent advances in the study of archaeal surface-layer (glyco)proteins are discussed.

This study investigated early adolescents’ psychophysiological response to a school-related stressor (SRS) as indexed by heart rate variability and examined the unique and interactive effects of heart rate variability and temperament on academic achievement. A total of 91 seventh graders watched an SRS video-clip while their heart rate variability was registered. Temperament and grades were also assessed. Heart rate variability decreased from baseline while watching the video-clip, indicating the activation of a stress response, and returned to basal level when recovering. Regression analyses revealed that among youth with an inhibited temperament, higher heart rate variability in the poststressor phase was related to better performance, whereas socially outgoing students performed well regardless of their recovery rate. These are among the first data to report on the link between early adolescents’ parasympathetic self-regulatory activity in response to an SRS, temperamental profiles, and academic functioning. Implications for theory and educational practice are discussed.
