Eduardo Gonalves, Saul Neves de Jesus
Open Journal of Psychiatry (OJPsych) , 2015, DOI: 10.4236/ojpsych.2015.54040
Abstract: The aim of this study is the investigation of the impact of stress of Portuguese subjects in situations of economic insufficiency and unemployment on executive function and quality of life and the coping strategies and resilience skills used. The sample consists of 41 participants. The psychometric instruments used are validated for Portuguese population, measure (perceived) stress, coping, material deprivation, resilience and quality of life, defined by World Health Organization. Executive function has been evaluated through performances at Stroop and Berg tasks. It has been concluded that, in this population, resilience skills and active coping strategies are positively correlated with quality of life. Quality of life is negatively correlated with material deprivation. Active coping strategies are supported by adequate executive function, which neurobiological substrate is dorso-lateral prefrontal cortex. Not active coping strategies correlate negatively with cognitive flexibility, suggesting the presence of a deficit at infero-lateral prefrontal cortex.
High frequency heart rate variability evoked by repetitive transcranial magnetic stimulation over the medial prefrontal cortex: A preliminary investigation on brain processing of acute stressor-evoked cardiovascular reactivity  [PDF]
Eduardo Manuel Gonalves, Saul Neves de Jesus
Open Journal of Psychiatry (OJPsych) , 2013, DOI: 10.4236/ojpsych.2013.34035
Abstract:

Introduction: Transcranial Magnetic Stimulation (TMS) is a non-invasive technique for brain stimulation. Repetitive TMS (rTMS) over the medial Prefrontal Cortex (mPFC), Broadman Area 10 (BA10) may stimulate transynaptically perigenual Anterior Cingulate Cortex (pACC, BA 33), insula, amigdala, hypothalamus and connected branches of the Autonomic Nervous System (ANS) involved in stressorevoked cardiovascular reactivity. Stressors are associated with an increase in sympathetic cardiac control, a decrease in parasympathetic control, or both, and, consequently, an increase in systolic/stroke volume, total vascular impedance/resistance and heart rate, a decrease of baroreflex sensitivity, i.e., an increase in blood pressure/arterial tension. Objectives and Aims: The present work aims, using TMS and accordingly to Gianaros modeling, based on functional neuroimaging studies and previous neuroanatomical data from animal models, to probe the connectivity of brain systems involved in stressor-evoked cardiovascular reactivity and to explore TMS potential as a tool for detection and stratification of individual differences concerning this reactivity and hemorreological risk factors correlated with the development of Coronary Heart Disease (CHD). Methods: Both subjects, a 52 years old male and a 40 years old female with previous increased Low Frequency (LF)/High Frequency (HF) Heart Rate Variability (HRV) ratios (respectively, 4.209/3.028) without decompensated cardiorespiratory symptoms, gave informed consent, and ethico-legal issues have been observed. Electroencephalographic (EEG) monitoring has been performed for safety purposes. Immediately after administration, over the mPFC, of 15 pulses of rTMS, during 60 second, with an inductive electrical current, at the stimulating coil, of 85.9 Ampère per

Abstract:


Introduction: Studies on attitudes and practices are increasingly used but not specifically related to the motivations for the use of reproductive health care among women of fertile age, living in urban areas and in different social contexts. Objectives: The aim of this study was to estimate the associations between the variables of social status (degree of poverty in the studied groups) and the variables of fecundity (representations, tensions, practices and control of fertility) and, in addition, to compare access to health care in the different studied groups, assessing the association between use of maternal health care and poverty in urban areas. Design: A case-control study was conducted in the Municipality of Lisbon, Portugal, with a total sample of 1513 women of fertile age: 499 cases of women considered very poor were selected from the database of beneficiaries of RSI (Social Welfare Payment for Inclusion); 1014 controls (two controls for each selected case), divided as 507 poor women selected from the other beneficiaries of Santa Casa da Misericórdia in Lisbon and 507 non-poor women selected from four Health Centers from the Municipality of Lisbon, Portugal. A total of 1054 women answered the questionnaire: 304 cases (response rate of 61%) and 750 (response rate of 74%) controls. The statistical analysis involved descriptive analysis and multinomial logistic regression. Results: The analysis confirms the association between poverty and patterns and representations of fecun

dity regarding pregnancy planning. The results of this study thus show the existence of different distributions on several variables and the gradients of poverty. Regarding access to health care, the major impact of poverty on women

Quantum Chemical Studies of Endofullerenes (M@C60) Where M = H2O, Li+, Na+, K+, Be2+, Mg2+, and Ca2+  [PDF]
Osmair Vital de Oliveira, Arlan da Silva Gonalves
Computational Chemistry (CC) , 2014, DOI: 10.4236/cc.2014.24007
Abstract: Quantum chemical calculations were performed to investigate the structural and electronic properties of seven endofullerenes. The interaction energies indicated that all of the chemical species are stable inside the fullerene for each complex. The ionization potential and electron affinity values suggest that the endofullerenes consisting of alkaline earth ions are the most reactive and that the dipole moment decreased according to the following order: Be2+@C60 (4.75) > Mg2+@C60 (3.14) > Ca2+@C60 (2.24) > Li+@C60 (1.26) > Na+@C60 (0.76) > H2O@C60 (0.24) > K+@C60 (0.00 Debye). These results imply that the solubility of endofullerenes in a polar solvent may increase from H2O@C60 to Be2+@C60. The energetic gaps indicate that Be2+@C60 and Mg2+@C60 possess a higher electrical conductivity, and the UV spectra show a shift in the bands to the visible light region. The results of this work may be useful for the development of new endofullerenes.
