- The present study examines several personal attributes that distinguish the personal profiles of individuals, from Indonesian and Swedish cultures, according to self-reports of positive and negative effect, stress and energy, self-esteem, hospital anxiety and depression, dispositional optimism and health. Indonesian participants expressed both more PA and more NA than Swedish participants but less stress and a higher energy-stress quotient than the Swedish participants. Additionally, the former expressed a higher level of optimism and self-esteem, but also more depression, and less impulsiveness than the latter. Younger participants expressed less positive affect and more negative affect and impulsiveness than older participants who expressed both more stress and a higher energy stress quotient. Regression analyses indicated that PA was predicted by optimism and health whereas NA was predicted by anxiety and depression and impulsiveness and counter predicted by health. The present findings are discussed according to the notion of emotional regulation according to which individuals differ in their use of emotion regulation strategies such as reappraisal and suppression, and these individual differences have implications for affect, well-being, and social relationships.

- Three studies that examined the links between affective personality, as constructed from responses to the Positive Affect (PA) and Negative Affect (NA) Scale (PANAS), and individuals' self-report of self-esteem, intrinsic motivation and Beck's Depression Inventory (BDI) depression in high school students and persons in working occupations are described. Self-report estimations of several other neuropsychiatric and psychosocial variables including, the Uppsala Sleep Inventory (USI), the Hospital Anxiety and Depression (HAD) test, Dispositional optimism, Locus of control, the Subjective Stress Experience test (SSE) and the Stress-Energy (SE) test, were also derived. Marked effects due to affective personality type upon somatic and psychological stress, anxiety and depression, self-esteem, internal and external locus of control, optimism, stress and energy, intrinsic motivation, external regulation, identified regulation, major sleep problems, problems falling asleep, and psychophysiological problems were observed; levels of self-esteem, self-motivation and BDI-depression all produced substantial effects on health and well-being. Regression analyses indicated PA was predicted by dispositional optimism (thrice), energy (thrice), and intrinsic motivation, and counter predicted by depression (twice) and stress (twice); and NA by anxiety (twice), stress (twice), psychological stress, identified regulation, BDI depression and psychophysiological problems, and counter predicted by internal locus of control and self-esteem. BDI-depression was predicted by negative affect, major sleep problems and psychophysiological problems (Study III), self-esteem by dispositional optimism and energy, and counter predicted by anxiety, depression and stress (Study I), and intrinsic motivation by dispositional optimism, energy, PA and self-esteem (Study II). These convergent findings are interpreted from a perspective of the cognitive-emotional expressions underlying behavioural or presymptomatic profiles presenting predispositions for health or ill health.

Tidskriftsartikel (refereegranskat)abstract
- A plethora of studies focusing on a ective personality attributes, positive a ect (PA) and negative a ect (NA), have measured ubiquitously self-reports of the Positive A ect and Negative A ect Schedule (PANAS), forming the basis of prevailing notions regarding health and well-being over di erent ethnical populations, gender and clinical and healthy volunteer populations [1-27]. Invariably, these studies have measured participants’ self-reported feelings of enthusiasm, activity, feelings of duty, control, strong, proud (i.e., PA) linking them to well- being, proneness to frequent exercise and agentic, cooperative, and spiritual behaviors (e.g., self-acceptance, goal-orientations, empathy, helpfulness, seeking support in faith, meaningfulness). In contrast, feelings such as anger, guilt, shame contempt, and distress (i.e., NA) are associated with anxiety, depressiveness, ill-being, rumination, inaction (e.g., low exercise frequency and passive leisure activities such as watching TV) and health problems. ese studies show that PA and NA ought to be viewed as separate entities, despite the temptation to view them as opposite poles on a continuum

- Male rat pups were administered 6-hydroxydopamine (6-OHDA, 75 μg, intracisternally, 30 min after desipramine, 25 mg/kg, s.c.) on Days 1 or 2 after birth, or were sham-operated (receiving vehicle). In four experiments, the acute effects of apomorphine, with or without pretreatment with MK-801 (0.03 mg/kg), upon motor activity in test chambers was measured. Acute treatment with apomorphine (0.1 mg/kg) increased locomotor, rearing and total activity markedly compared to both the acute saline administered 6-OHDA rats and the sham-operated rats administered saline. Acute MK-801 (0.03 mg/kg) co-administered shortly before (5 min) apomorphine (0.3 or 1.0 mg/kg) reduced markedly locomotion and total activity in 6-OHDA-treated and sham-operated rats. Rearing behaviour was increased in both the 6-OHDA groups of rats. Acute MK-801 increased activity in the 6-OHDA-treated rats, which was not observed in sham-operated rats. At the 0.3 and 1.0 mg/kg doses of apomorphine, neonatal 6-OHDA treament increased all three parameters of motor activity. Acute treatment with apomorphine (0.1 mg/kg) induced different effects on the motor activity of 6-OHDA-treated and sham-operated mice. In sham-operated rats apomorphine reduced motor activity during the 1st 30-min period but increased locomotion and total activity, but not rearing, during the 2nd and 3rd periods, whereas in 6-OHDA-treated rats, apomorphine increased locomotor, rearing and total activity markedly. Dopamine loss and serotonin elevation in the striatum and olfactory tubercle were confirmed. The present findings confirm the influence of non-competitive glutamate antagonists in attenuating the behavioural supersensitivity to dopamine antagonists.

Tidskriftsartikel (refereegranskat)abstract
- The prevailing utility, and indeed necessity, of clinical staging models applied in considerations of neuropsychiatric disease progressions is discussed from the perspectives of schizophrenia spectrum disorders and affective disorders, cannabis in schizopsychotic disorder, incidences of affect and psychosis, staging disorders in aging and the indices and prevalence of apathy. There would appear to be a strong current consensus that the pursuit of clinical staging of these and other brain disease states has contributed a systematic conceptual instrument to facilitate the better understanding, diagnosis, prognosis and treatment as derived from a multitude of genetic predispositions, symptoms and syndromes, early-onset and prodromal phases, recurrences and relapses, that have complicated the situation of the patient. Through a staging determination of the disorder, elements of diagnosis will describe the progression of symptoms/syndromes through pre-onset, prodromal, first-episode, recurrences and relapses, and treatment resistance thereby facilitating the eventual prognosis, intervention alternatives and treatment. This approach varies from observations of individuals at early stages of development (infancy, childhood, adolescece) to early middle age, in the case of diseases expressed through the aging processes. Essentially, the major contribution of the staging model may lie in the early identification, diagnosis, and treatments of disorders that afflict the brain and central nervous system.

- © Società Editrice Universo (SEU).Exercise, as a potent epigenetic regulator, implies the potential to counteract pathophysiological processes and alterations in most cardiovascular/respiratory cells and tissues not withstanding a paucity of understanding the underlying molecular mechanisms and doseresponse relationships. In the present account, the assets accruing from physical exercise and its influence upon executive functioning are examined. Under conditions of neuropsychiatric and neurologic ill-health, age-related deterioration of functional and biomarker indicators during healthy and disordered trajectories, neuroimmune and affective unbalance, and epigenetic pressures, exercise offers a large harvest of augmentations in health and well-being. Both animal models and human studies support the premise of manifest gains from regular exercise within several domains, besides cognitive function and mood, notably as the agency of a noninvasive, readily available therapeutic intervention.

Cognitive Symptoms Facilitatory for Diagnoses in Neuropsychiatric Disorders: Executive Functions and Locus of Control

Ingår i: Neurotoxicity Research. ; 14:2,3, s. 205-225

Tidskriftsartikel (refereegranskat)abstract
- Cognitive symptoms, considered in conjunction both with their regional brain and biomarkers as well as affective, attributional and neurodevelopmental components, demonstate everincreasing complexity to facilate conceptualization yet, unavoidably, bedevil diagnosis in neuropsychiatry even before considerations of the enigmatic processes in memory, such as executive function and working memory, are draw into the myriads of equations that await remedial interpretations. Prefrontal and limbic regions of the brain are involved in a diversity of expressions of cognition, normal or dysfunctional, at synaptic, intracellular and molecular levels that mobilize a concatenation of signaling entities. Serotoninergic neurotransission at prefrontal regions directs cogntive-affective entities that mediate decision-making and goal-directed behaviour. Clinical, non-clinical and basic studies challenge attempts to consolidate the multitude of evidence in order to obtain therapeutic notions to alleviate the disordered status of the diagnosed and yet-to-be diagnosed individuals. Locus of control, a concept of some utility in health-seeking procedures, is examined in three self-report studies from the perspective of a cognitive- emotional situation through observations of ordinary, 'healthy' young and middle-aged individuals, to assess the predictors of internal and external locus of control. A notion based on high level executive functioning in the dorsolateral prefrontal cortex (DLPFC) in individuals characterised by internal locus of control is contrasted with a hypofunctional executive DLPFC, characterising individuals that express an external locus of control, is discussed.

Tidskriftsartikel (refereegranskat)abstract
- In two experiments, MPTP was administered to C57/BL6 mice according to a single-dose weekly regime (MPTP: 1 x 30 mg/kg on the fifth day of the week, Friday, over 4 weeks) with vehicle group (Vehicle: 1 x 5 ml/kg) treated concurrently. Exercise schedules (delayed) were introduced either at the beginning of the week after the second MPTP injection (MPTP + Exercise(2) group), or at the beginning of the week after the fourth MPTP injection (MPTP + Exercise(4) group). Wheel-running was provided on the first 4 days of each week (Monday-Thursday) more than 30-min periods. In Experiment I, wheel-running exercise was introduced either after 2 or 4 weeks after MPTP/Vehicle. MPTP and Vehicle groups not provided access to the running wheels were placed in single cages within the wheel-running room over 30-min concomitantly with the wheel-running groups. In Experiment II, wheel-running exercise was introduced 2 weeks after MPTP/Vehicle but a no-exercise control group with non-revolving wheel included (MPTP-Wheel). In both experiments, spontaneous motor activity tests during 60-min intervals were performed at the end (Fridays) of weeks 1, 2, 3, 4, 6, 8, and 10, where the week on which the first injection of MPTP was the first week; in the case of weeks 1-4, this was immediately before MPTP/Vehicle injections. It was observed that the introduction of the exercise schedule after the second MPTP injection, but not after the fourth injection, restored motor activity that had been markedly elevated by the end of the tenth week. Subthreshold administration of l-dopa tests was performed after the spontaneous motor activity tests 6, 8 and 10; these indicated significant effects of exercise, MPTP + Exercise(2) group, on Tests 6 and 8, but not Test 10. The physical exercise schedule in that group also showed markedly attenuated loss of dopamine (DA). Restoration of MPTP-induced motor activity deficits and DA loss was a function of the point at which exercise was introduced, in the present case after two administrations of the neurotoxin. In Experiment II, physical exercise markedly attenuated the hypokinesic effect of MPTP in the exercise condition, MPTP-exercise, but not in the non-exercise conditions, MPTP-Cage and MPTP-Wheel, for both spontaneous motor activity and l-dopa-induced activity. MPTP-induced loss of DA was also attenuated by exercise.

Tidskriftsartikel (refereegranskat)abstract
- This exploratory report presents the contents of a large data-base consisting of psychometric measurement of personality-related attributes of individuals who underwent the recruitment process by completing the JobMatchTalent instrument that was developed from principles of occupational psychology. On the basis of individuals’, who applied for corporate or governmental leadership positions, responses, the correlations between applicants’ age and personal attributes was obtained. Correlational and regression analyses were used to explore differences between younger and older potential executive participants. These indicated that younger leadership applicants enjoyed an advantage with regard to: ”Focus-on-details”, ”Focus-on-order”, ”Own motivation”, ”Concentration”, ”Will-power”, ”Winner-instinct”, ”Visions-for-the-future”, whereas older leadership applicants enjoyed an advantage with regard to: ”Sphere-of-influence”, ”Tolerant attitude” and ”Trust-in-others”. The levels of stress-sensitivity, strategic focus, energy and communication, as expressed by younger and older recruitment applicants seeking executive positions, were comparable. At higher age levels, the leadership candidates expressed less focus on the tasks and less orientation towards their own ambitions but were rather more concerned with developing their staff, building relations and ‘team-spirit’
