Homosexuality: Brief History and Considerations on the Manifestation of Jealousy in Homosexual Relationships  [PDF]
Thiago de Almeida, Rafael Diniz de Lima, Joao Marcos Panho, Paulo Franklin Canezin
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104612
Abstract:
The jealousy is a reaction to a real or imagined threat perceived at an estimated relationship. The jealousy is present to a greater or lesser extent in all at some point in life. This study aims to understand how jealousy is experienced by homosexual couples, identifying if such mechanisms are similar or different of the heterosexual jealousy. To address this objective, we performed a systematic review of the literature on this subject. It can be observed that jealousy is present in affective-sexual gay relationships, being a protective factor for the maintenance of the loving relationship minimizing the risk of sexual and emotional loss. It highlighted the need for new issues to understand the homosexual jealousy can be more damaging relationships than in heterosexual jealousy and identify if cultural conditions affect the manifestation of it among homosexuals.
O psíquico e o social numa perspectiva metapsicológica: o conceito de identifica??o em freud
Guimar?es, Veridiana Canezin;Celes, Luiz Augusto M.;
Psicologia: Teoria e Pesquisa , 2007, DOI: 10.1590/S0102-37722007000300014
Abstract: in this article, the metapsychological concept of identification is simultaneously understood as the basis for the mechanisms of the individual?s insertion in social groups - in a cultural context - as well as a key factor in the overcoming of the oedipus conflict and the comprehension of the constitution of the self. it is suggested that the concept of identification enables us to understand psychic and social factors as elements in the constitution of the individual which, therefore, should not be considered separately. this also indicates the metapsychological character that the social factor acquires in freud?s psychoanalytical theory. the main source for the current analysis is the 1921 essay by freud entitled group psychology and the analysis of the ego.

Abstract: purpose: to evaluate the in vivo alterations on ketone bodies metabolism after cerebral ischemia/reperfusion through an experimental model of brain ischemia induced by simple occlusion of common carotid arteries (ccas) in wistar rats. methods: forty-eight male wistar rats were randomly distributed on two groups (s - sham; t - test) and further redistributed into four times sets of study. after bilateral occlusion of ccas for 30min, the animals of group t were allowed reperfusion for 0, 5, 10 and 15min. samples of cerebral tissue and systemic arterial blood were collected and the metabolites acetoacetate (act) and beta-hydroxybutyrate (bhb) were determined. results: cerebral act and bhb levels increased significantly in group t after 30min of carotid occlusion (time 0). the highest brain ketone bodies (act+bhb) concentration was verified at 5min of reperfusion, decreasing after 10min of recirculation. systemic ketone bodies levels increased similarly between test and sham groups. group s demonstrated a significant increase in cerebral and systemic act and bhb concentrations mainly after 40-45min of study. conclusions: the partial transient acute global brain ischemia induced by the bilateral carotid occlusion in wistar rats triggered ketogenesis probably due to a central stimulation of catecholamine secretion. there was an increased cerebral uptake of ketone bodies following brain ischemia, reaffirming these metabolites as alternative energy substrates under conditions of cerebral metabolic stress as well as its potential role on neuroprotection. the greatest changes in ketone bodies metabolism were verified at initial minutes of recirculation as a result of the reperfusion injury phenomenon.

Abstract: purpose: to describe alterations on the energy metabolism after cerebral ischemia/reperfusion, through an experimental model of reversible global ischemia, by simple occlusion of common carotid arteries (ccas) in rats of wistar lineage. methods: forty-eight male wistar rats were randomly distributed on two groups (c - control; t - test) and further redistributed into four times sets of study. after bilateral occlusion of ccas for 30min, the animals of group t were allowed reperfusion for 0, 5, 10 and 15min. samples of cerebral tissue and systemic arterial blood were collected and the metabolites d-glucose (gli), pyruvate (prv), lactate (lct) and adenosine triphosphate (atp) quantified. results: increases of gli and prv blood values of, respectively, 85,00% (p<0,05) and 51,72% (p<0,01) were observed at 5min of reperfusion, which reflect a systemic response to the cerebral ischemia. the brain's lct remained stable despite a reduction of 52,66% (p<0,05) in its blood concentration at 15min of reperfusion. the cerebral concentrations of atp decreased 85,40% (p<0,05) after ischemia, followed by an augmentation of 3.033,40% (p<0,05) at 5min of reperfusion, becoming evident the recovery of cell respiration by fosforilation pathway. conclusions: the proposed experimental model produced partial transitory global ischemia, with systemic repercussions. the greatest metabolic alterations were verified in the initial minutes of reperfusion, typifying reperfusion injury. such observations prove its value as an important instrument in the study of physiopathology and therapeutic sources of ischemic cerebrovascular disease.

Pesquisa Veterinária Brasileira , 1998,
Abstract: Quinze focos de meningoencefalite por herpesvírus bovino-5 (BHV-5) foram diagnosticados entre agosto de 1993 e dezembro de 1996, sendo 14 provenientes do estado do Mato Grosso do Sul e um do estado de S o Paulo. A doen a ocorreu em diversos municípios e em diferentes épocas do ano. Foram afetados bovinos de 6 a 60 meses de idade, com uma morbidade de 0,05% a 5% e letalidade próxima a 100%. Os sinais clínicos foram exclusivamente nervosos e o curso da enfermidade variou de 1 a 15 dias. As principais les es histológicas detectadas foram meningite e encefalite difusa com malacia do córtex cerebral e presen a de corpúsculos de inclus o intranucleares em astrócitos e neur nios. O vírus foi isolado do cérebro de 11 de um total de 12 animais, e sua identidade confirmada por imunoperoxidase, utilizando-se anticorpos monoclonais específicos. Os surtos de encefalite por BHV-5 representam 5% dos diagnósticos realizados em bovinos pelo Hospital Veterinário da Universidade Federal do Mato Grosso do Sul. Os resultados deste trabalho evidenciam a importancia da doen a no Mato Grosso do Sul e indicam a necessidade de incluir a encefalite por BHV-5 no diagnóstico diferencial de outras doen as do sistema nervoso de bovinos frequentes no Estado.
Effects of Academic Stress and Perceived Social Support on the Psychological Wellbeing of Adolescents in Ghana  [PDF]
Franklin N. Glozah
Open Journal of Medical Psychology (OJMP) , 2013, DOI: 10.4236/ojmp.2013.24022
Abstract: The purpose of this study was to examine how academic stress and perceived social support influence the psychological wellbeing of Senior High School students in Ghana. Two hundred and twenty six male and female students participated. The general health questionnaire, student life-stress inventory and perceived social support from family and friends scales were used to assess psychological wellbeing, academic stress and perceived social support respectively. The results indicated that perceived social support buffered the effects of academic stress on psychological wellbeing. Girls reported higher scores on perceived social support but reported more depression. Boys reported higher academic stress and better psychological wellbeing, and these have been attributed partly to the socialisation role of gender. These results have policy implications in respect of the creation of a cordial school environment as well as encouraging a healthy interpersonal relationship between adolescents and their family and friends with the aim of reducing academic stress appraisal which is inimical to the psychological wellbeing of adolescents.
Heterotrophic and Autotrophic Soil Respiration under Simulated Dormancy Conditions  [PDF]

Open Journal of Forestry (OJF) , 2015, DOI: 10.4236/ojf.2015.53024
Abstract: Carbon cycling research has increased over the past 20 years, but less is known about the primary contributors to soil respiration (i.e. heterotrophic and autotrophic) under dormant conditions. It is understood that soil CO2 effluxes are significantly lower during the winter of temperate ecosystems and assumed microorganisms dominate efflux origination. We hypothesized that heterotrophic contributions would be greater than autotrophic under simulated dormancy conditions. To test this hypothesis, we designed an experiment with the following treatments: combined autotrophic heterotrophic respiration, heterotrophic respiration, autotrophic respiration, no respiration, autotrophic respiration in vermiculite, and no respiration in vermiculite. Engelmann spruce seedlings and soil substrates were placed in specially designed respiration chambers and soil CO2 efflux measurements were taken four times over the course of a month. Soil microbial densities and root volumes were measured for each chamber after day thirty-three. Seedling presence resulted in significantly higher soil CO2 efflux rates for all soil substrates. Autotrophic respiration treatments were not representative of solely autotrophic soil CO2 efflux due to soil microbial contamination of autoclaved soil substrates; however, the mean autotrophic contributions averaged less than 25% of the total soil CO2 efflux. Soil microorganism communities were likely the primary contributor to soil CO2 efflux in simulated dormant conditions, as treatments with the greatest proportions of microbial densities had the highest soil CO2 efflux rates. Although this study is not directly comparable to field dormant season soil CO2 effluxes of Engelmann spruce forest, as snowpack is not maintained throughout this experiment, relationships, and metrics from such small-scale ecosystem component processes may yield more accurate carbon budget models.

Abstract: effect of aedes fluviatilis saliva on the development of plasmodium gallinaceum experimental infection in gallus (gallus) domesticus was studied in distinct aspects. chickens subcutaneously infected with sporozoites in the presence of the mosquito salivary gland homogenates (sgh) showed higher levels of parasitaemia when compared to those ones that received only the sporozoites. however, the parasitaemia levels were lower among chickens previously immunized by sgh or non-infected mosquito bites compared to the controls, which did not receive saliva. high levels of anti-saliva antibodies were observed in those immunized chickens. moreover, 53 and 102 kda saliva proteins were recognized by sera from immunized chickens. after the sporozoite challenge, the chickens also showed significant levels of anti-sporozoite antibodies. however, the ability to generate anti-sporozoites antibodies was not correlated to the saliva immunization. our results suggest that mosquito saliva components enhance p. gallinaceum parasite development in naive chickens. however, the prior exposure of chickens to salivary components controls the parasitemia levels in infected individuals.
