Protozooplankton characterization of two contrasting sites in a tropical coastal ecosystem (Guanabara Bay, RJ)
Gomes, Eli Ana Traversim;Santos, Viviane Severiano dos;Tenenbaum, Denise Rivera;Villac, Maria Célia;
Brazilian Journal of Oceanography , 2007, DOI: 10.1590/S1679-87592007000100004
Abstract: much time and resources have been invested in understanding plankton dynamics in guanabara bay (brazil), but no attention has been devoted to the protozooplankton. to fulfill this lacuna, abundance and composition of protozooplankton were investigated from january to december - 2000 in fortnightly surface water samplings at two distinct water quality sites (urca - closer to the bay entrance, more saline and cleaner waters; ramos - inner reaches, hypereutrophic waters). the density at urca (103 - 105 cell.l-1) was one to three orders of magnitude lower than at ramos (104 - 105 cell.l-1). a seasonal trend for nanoplankton and protozooplankton was more evident at urca, but both sites had lower densities during the colder period. small heterotrophic dinoflagellates (20-30 mm) were dominant in over 50% of the samples. the protozooplankton abundance and composition reflected the distinct trophic conditions states found at the bay. during the wet-warm season, non-oligotrich ciliates were representative of ramos site with gymnodiniaceae dinoflagellates, while tintinnids and heterotrophic dinoflagellates were predominantly found at urca mainly during the dry-cold season. this first descriptive study towards the understanding of the intricate relationships among the microbial food web components reveals that protozooplankton can be a good indicator of water quality conditions at the bay.

Abstract: Organ injury caused by ischemia and anoxia during prolonged cardiac arrest is compounded by reperfusion injury that occurs when spontaneous circulation is restored. Mild hypothermia (32-35oC) is neuroprotective through several mechanisms, including suppression of apoptosis, reduced production of excitotoxins and free radicals, and anti-inflammatory actions. Experimental studies show that hypothermia is more effective the earlier it is started after return of spontaneous circulation (ROSC). Two randomized clinical trials show improved survival and neurological outcome in adults who remained comatose after initial resuscitation from prehospital VF cardiac arrest, and who were cooled after ROSC. Different strategies can be used to induce hypothermia. Optimal timing of therapeutic hypothermia for cardiac ischemia is unknown. In patients who failed to respond to standard cardiopulmonary resuscitation, intra-arrest cooling using ice-cold intravenous (i.v.) fluid improved the chance of survival. Recently, fasudil, a Rho kinase inhibitor, was reported to prevent cerebral ischaemia in vivo by increasing cerebral blood flow and inhibiting inflammatory responses. In future, two different kinds of protective therapies, BCL-2 overexpression and hypothermia, will both inhibit aspects of apoptotic cell death cascades, and that combination treatment can prolong the temporal 'therapeutic window' for gene therapy.

Vojnosanitetski Pregled , 2003, DOI: 10.2298/vsp0303361a
Abstract: A case of an by digoxin under unusual circumstances is reported. An 80-year-old man, previously on long-term digoxin treatment, started consuming St John’s wort herbal tea (2 000 ml/daily) because of frequent episodes of depression. After the cessation of consuming herbal tea containing Hypericum perforatum, digoxin poisoning developed in our patient. Electrocardiography revealed nodal bradicardia 36/min and bigeminy. Manifested symptoms were the consequence of interaction between digoxin and Hypericum perforatum which were consumed simultaneously, and the cessation of consuming St John’s wort herbal tea afterwards. Therapy was the same as in the standard digitalis poisoning. Consumers of St John’s wort combined with medical products are advised not to discontinue tea consumption on their own, without consulting their physician.
CAS-Based Approach for Automatic Data Integration  [PDF]
Eli Rohn
American Journal of Operations Research (AJOR) , 2013, DOI: 10.4236/ajor.2013.31A017
Abstract:

Research of automatic integration of structured and semi-structured data has not resulted in success over the past fifty years. No theory of data integration exists. It is unknown what the theoretical necessary requirements are, to fully support automatic data integration from autonomous heterogeneous data sources. Therefore, it is not possible to objectively evaluate if and how much new algorithms, techniques, and specifically Data Definition Languages, move towards meeting such theoretical requirements. To overcome the serious reverse salient the field and industry are in, it will be helpful if a data integration theory would be developed. This article proposes a new look at data integration by using complex adaptive systems principles to analyze current shortcomings and propose a direction that may lead to a data integration theory.

Autonomous Data Exchange: The Malady and a Possible Path to Its Cure  [PDF]
Eli Rohn
Intelligent Information Management (IIM) , 2015, DOI: 10.4236/iim.2015.71003
Abstract: Data exchange is a goal-oriented social communications system implemented through computerized technology. Data definition languages (DDLs) provide the syntax for communicating within and between organizations, illocutionary acts, such as informing, ordering and warning. Data exchange results in meaning-preserving mapping between an ensemble (a constrained variety) and its external (unconstrained) variety. Research on unsupervised structured and semi-structured data exchange has not produced any significant successes over the past fifty years. As a step towards finding a solution, this article proposes a new look at data exchange by using the principles of complex adaptive systems (CAS) to analyze current shortcomings and to propose a direction that may indeed lead to workable and mathematically grounded solution. Three CAS attributes key to this research are variety, tension and entropy. We use them to show that older and contemporary DDLs are identical in their core, thus explaining why even XML and Ontologies have failed to a create fully automated data exchange mechanism. Then we show that it is possible to construct a radically different DDL that overcomes existing data exchange limitations—its variety, tension and entropy are different from existing solutions. The article has these major parts: definition of key CAS attributes; quantitative examination of representative old and new DDLs using these attributes; presentation of the results and their pessimistic ramification; a section that proposes a new theoretical way to construct DDLs that is based entirely on CAS principles, thus enabling unsupervised data exchange. The theory is then tested, showing very promising results.
Enfermedades virales emergentes y reemergentes

Iatreia , 1996,
Abstract: Los virus no son una excepción al principio de que toda forma de vida de hoyes el producto de la evolución de información gen ética preexistente. Tradicionalmente se ha reconocido que ta expresión clínica de las enfermedades virales cambia con el tiempo; molecularmente se ha demostrado que esos cambios fenotípicos son el producto de variaciones en el genoma viral. La tasa de cambio gen ético y fenotípico no es la misma en todos los agentes virales y ello está determinado, principalmente, por factores intrínsecos del virus, como la naturaleza de su ácido nucleico, y por la longevidad y tasa reproductiva del huésped.

Vojnosanitetski Pregled , 2012, DOI: 10.2298/vsp1201016l
Abstract: Background/Aim. Proper mouth and teeth hygiene has influence on the prevention of a great number of diseases and very often some of them are not related only to oral cavity. Most frequent diseases of mouth and teeth such as caries and periodontal diseases are caused, among other factors, by poor oral hygiene. They are also more frequent in young population. The aim of this study was to estimate the influence of sociodemographic characteristics and hygienic habit on oral health in children aged 11-15 years. Methods. This crosssectional study was conducted by the dental teams in dentist surgeries in Tivat Health Center between May and September 2009. The sample consisted of patients 11 to 15 years of age. A questionnaire and dental examination of mouth and teeth were used as research instruments. The examinations were conducted in accordance with the World Health Organization methodology and criteria. The data obtained from the interviews were correlated with those obtained from the clinical examinations. Results. The results show that the majority of respondents brush their teeth twice a day and visit the dentist once in every six months. The research also shows that 57% respondents have caries of deciduous teeth and over 63% respondents of permanent teeth. Gingivitis was found in 14% and orthodontic anomalies in 44.7% respondents. A half of respondents who brush their teeth rarely have problems with gingivitis. There is a highly statistically significant difference between the occurrence of gingivitis and the frequency of teeth brushing. Conclusion. There is a significant difference between mouth and oral hygiene and sex as well as other sociodemographic characteristics of respondents. The study showed the correlation between occurrence of caries and the gingivitis and frequency of teeth brushing and dental visits.
Molduras públicas de performatividade queer e representa??o mediática em Portugal
Santos,Ana Cristina;
Ex aequo , 2009,
Abstract: the media attention towards lgbt issues after the 1990s generated impacts on social representations of sexual orientation and gender identity, as well as on the portuguese lgbt movement itself, which was forced to an increased political reflexivity about its own individual and/or collective image. consequently, the subversive public display of the body is often excluded, even within the lgbt movement. such stance mirrors an ideological choice that tends to disconnect lgbt activism of its central role in deconstructing the dominant heteronormative and heterosexist culture, representing disengagement in relation to the queer venture. contributing to this debate are processes of ?normalization of homosexuality? which result from, and create, a narrow understanding of the frames of queer performativity considered (un)acceptable in the public sphere.
Changing epidemics
Santos,Ana Cristina;
Arquivos de Medicina , 2006,
Abstract: the world is now facing a global change in the patterns of disease. non-communicable diseases such as diabetes or cardiovascular disease are fasting replacing the traditional epidemics. these changes are affecting mainly developing countries, but its impact is fully observed in the developed world. cardiovascular diseases are a main cause of death among portuguese adults, and changes in the prevalence of modifiable risk factors such as obesity or tobacco consumption, could lead to important changes in the morbidity and mortality of such diseases. however, national estimates indicate that obesity and tobacco consumption are the two most common modifiable risk factors in our population and unfortunately their prevalence estimates are not expected to decrease in the next years.
Sexualidades politizadas: ativismo nas áreas da AIDS e da orienta??o sexual em Portugal
Santos, Ana Cristina;
Cadernos de Saúde Pública , 2002, DOI: 10.1590/S0102-311X2002000300009
Abstract: this article analyzes how both the portuguese state and civil society have addressed the aids issue, focusing on participation by the lesbian, gay, bisexual, and transsexual community (lgbt) in the struggle against aids. the article begins by describing the situation of lgbt individuals in portugal during the 1990s, when the portuguese lgbt movement emerged and grew, and then characterizes the evolution of hiv/aids in portugal, analyzing the relationship between civil society and sexuality in general and the situation of the epidemic in the country in particular, considering key facts, nongovernmental organizations, and state initiatives. special attention is given to the role played by lgbt organizations in the struggle against hiv. finally, the article reflects on the future of the struggle against both aids and discrimination in the 21st century, considering recent events in the country and the guidelines recommended by international policies.
