Evolução do ciclo vital de Poecilia vivipara (Cyprinodontiformes: Poeciliidae) em um gradiente de predação

O presente estudo teve como objetivo testar previsões da teoria sobre a influência da predação na evolução dos ciclos vitais. Como modelo de estudo, foram estudadas populações do peixe Poecilia vivipara que habitam o Parque Nacional da Restinga de Jurubatiba, no sistema lagunar Norte-Fluminense, estado do Rio de Janeiro. Neste sistema lagunar, P. vivipara está sujeita à predação por peixes piscívoros (e.g. a traíra Hoplias malabaricus) em parte das lagoas, mas está livre destes predadores em outras lagoas. Foram estudadas três lagoas em que P. vivipara coexiste com seus predadores piscívoros e três em que estes estão ausentes. A ictiofauna das seis lagoas foi amostrada através de redes de arrasto e espinhel. Em laboratório, as fêmeas e os machos de P. vivipara foram dissecados para remoção de suas gônadas. As gônadas das fêmeas foram categorizadas em seis diferentes estágios de desenvolvimento. A partir do terceiro estágio, os embriões foram contados e medidos (maior diâmetro). Os exemplares de P. vivipara e suas gônadas foram secos em estufa a 60ºC e pesados em balança analítica (0,01 mg). Os aspectos do ciclo vital analisados foram: (1) investimento reprodutivo das fêmeas (massa gonadal/massa total da fêmea); (2) índice gonadossomático dos machos (massa gonadal/massa total do macho); (3) fecundidade (número de embriões); (4) comprimento médio dos embriões; e (5) massa seca média dos embriões (massa gonadal/fecundidade). O efeito da predação foi testado com uma ANCOVA aninhada, com regime de predação (alta intensidade, baixa intensidade), população de origem (aninhada dentro do regime de predação) e coleta como variáveis independentes, e massa somática e estágio embrionário como covariáveis. De acordo com o previsto pela teoria, as fêmeas dos ambientes de baixa predação apresentaram embriões maiores, mas, contrariando as previsões teóricas, também apresentaram maior fecundidade e...

A família e o indivíduo no curso vital: compreensão trigeracional sobre a morte e o morrer

The death has been considered a forbidden issue. To develop studies that promote reflections about it allows the enlargement of the understanding as regarding the death as about life in that both are related during the human existence. This research aimed to understand the death’s conceptions and family meanings to three different generations. For this goal, through phenomenological methodology, were achieved individual interviews with adolescents, both his parents and the grandfather, all belonging to the same family. After to understand the participant’s experiences, six thematic categories were created: a) Death’s meanings; b) The death of himself; c) The death of another and/or its possibility; d) Sources of support; e) The family in the death’s presence; f) The life in the death’s inevitability presence. From these categories, the dates were phenomenologically. The participants showed similar reports in several times, confirming the literature that says that the daily life experiences among the family members take the family to form a peculiar way to understand and an interpret their experiences. This identity family, however, did not prevent each participant to develop his particular history based in idiosyncratic elements and associated with the stage of life cycle that it is. The reports showed that the prohibition of death in society is still very present, which prevents that discussions about the issue are present in daily life. This study provided for participants to reflect on their experiences around the phenomenon of death and, consequently, about the inseparable relationship between living and dying. It has also reiterated the literature, showing the similarity of views among the family members of three generations face a vital phenomenon potentially impacting the life cycle of individual and family.

Clinical Evaluation of the Effectiveness of Different Bleaching Therapies in Vital Teeth

The aims of this in vivo study were to compare the effectiveness and color stability of at-home and in-office bleaching techniques and to evaluate whether the use of light sources can alter bleaching results. According to preestablished criteria, 40 patients were selected and randomly divided into four groups according to bleaching treatment: (1) at-home bleaching with 10% carbamide peroxide, (2) in-office bleaching with 35% hydrogen peroxide (HP) without a light source, (3) in-office bleaching with 35% HP with quartz-tungsten-halogen light, and (4) in-office bleaching with 35% HP with a light-emitting diode/laser. Tooth shade was evaluated using the VITA Classical Shade Guide before bleaching as well as after the first and third weeks of bleaching. Tooth shade was evaluated again using the same guide 1 and 6 months after the completion of treatment. The shade guide was arranged to yield scores that were used for statistical comparison. Statistical analysis using the Kruskal-Wallis test showed no significant differences among the groups for any time point (P > .01). There was no color rebound in any of the groups. The bleaching techniques tested were equally effective. Light sources are unnecessary to bleach teeth. (Int J Periodontics Restorative Dent 2012;32:303-309.)

Estimation of lung vital capacity before and after coronary artery bypass grafting surgery: a comparison of incentive spirometer and ventilometry

Abstract Background Measurement of vital capacity (VC) by spirometry is the most widely used technique for lung function evaluation, however, this form of assessment is costly and further investigation of other reliable methods at lower cost is necessary. Objective: To analyze the correlation between direct vital capacity measured with ventilometer and with incentive inspirometer in patients in pre and post cardiac surgery. Methodology Cross-sectional comparative study with patients undergoing cardiac surgery. Respiratory parameters were evaluated through the measurement of VC performed by ventilometer and inspirometer. To analyze data normality the Kolmogorov-Smirnov test was applied, for correlation the Pearson correlation coefficient was used and for comparison of variables in pre and post operative period Student's t test was adopted. We established a level of ignificance of 5%. Data was presented as an average, standard deviation and relative frequency when needed. The significance level was set at 5%. Results We studied 52 patients undergoing cardiac surgery, 20 patients in preoperative with VC-ventilometer: 32.95 ± 11.4 ml/kg and VC-inspirometer: 28.9 ± 11 ml/Kg, r = 0.7 p < 0.001. In the post operatory, 32 patients were evaluated with VC-ventilometer: 28.27 ± 12.48 ml/kg and VC-inspirometer: 26.98 ± 11 ml/Kg, r = 0.95 p < 0.001. Presenting a very high correlation between the evaluation forms studied. Conclusion There was a high correlation between DVC measures with ventilometer and incentive spirometer in pre and post CABG surgery. Despite this, arises the necessity of further studies to evaluate the repercussion of this method in lowering costs at hospitals.

Integration of Internet of Things and Cloud computing. A case study on vital signs monitoring.

Il progresso scientifico e le innovazioni tecnologiche nei campi dell'elettronica, informatica e telecomunicazioni, stanno aprendo la strada a nuove visioni e concetti. L'obiettivo della tesi è quello d'introdurre il modello del Cloud computing per rendere possibile l'attuale visione di Internet of Thing. Nel primo capitolo si introduce Ubiquitous computing come un nuovo modo di vedere i computer, cercando di fare chiarezza sulla sua definizione, la sua nascita e fornendo un breve quadro storico. Nel secondo capitolo viene presentata la visione di Internet of Thing (Internet delle “cose”) che si avvale di concetti e di problematiche in parte già considerate con Ubiquitous computing. Internet of Thing è una visione in cui la rete Internet viene estesa agli oggetti di tutti i giorni. Tracciare la posizione degli oggetti, monitorare pazienti da remoto, rilevare dati ambientali sono solo alcuni esempi. Per realizzare questo tipo di applicazioni le tecnologie wireless sono da considerare necessarie, sebbene questa visione non assuma nessuna specifica tecnologia di comunicazione. Inoltre, anche schede di sviluppo possono agevolare la prototipazione di tali applicazioni. Nel terzo capitolo si presenta Cloud computing come modello di business per utilizzare su richiesta risorse computazionali. Nel capitolo, vengono inizialmente descritte le caratteristiche principali e i vari tipi di modelli di servizio, poi viene argomentato il ruolo che i servizi di Cloud hanno per Internet of Thing. Questo modello permette di accelerare lo sviluppo e la distribuzione di applicazioni di Internet of Thing, mettendo a disposizione capacità di storage e di calcolo per l'elaborazione distribuita dell'enorme quantità di dati prodotta da sensori e dispositivi vari. Infine, nell'ultimo capitolo viene considerato, come esempio pratico, l'integrazione di tecnologie di Cloud computing in una applicazione IoT. Il caso di studio riguarda il monitoraggio remoto dei parametri vitali, considerando Raspberry Pi e la piattaforma e-Health sviluppata da Cooking Hacks per lo sviluppo di un sistema embedded, e utilizzando PubNub come servizio di Cloud per distribuire i dati ottenuti dai sensori. Il caso di studio metterà in evidenza sia i vantaggi sia le eventuali problematiche che possono scaturire utilizzando servizi di Cloud in applicazioni IoT.

Blood aspiration as a vital sign detected by postmortem computed tomography imaging

Blood aspiration is a significant forensic finding. In this study, we examined the value of postmortem computed tomography (CT) imaging in evaluating findings of blood aspiration. We selected 37 cases with autopsy evidence of blood in the lungs and/or in the airways previously submitted to total-body CT scanning. The CT-images were retrospectively analyzed. In one case with pulmonary blood aspiration, biopsy specimens were obtained under CT guide for histological examination. In six cases, CT detected pulmonary abnormalities suggestive of blood aspiration, not mentioned in the autopsy reports. CT reconstructions provided additional data about the distribution and extent of aspiration. In one needle-biopsied case, the pulmonary specimens showed blood in the alveoli. We suggest the use of CT imaging as a tool complementary to traditional techniques in cases of blood aspiration to avoid misdiagnosis, to guide the investigation of lung tissue, and to allow for more evidence-based inferences on the cause of death.

Tissue response and wound healing after placement of two types of bioengineered grafts containing vital cells in submucosal maxillary pouches: an experimental pilot study in rabbits

PURPOSE: This pilot study evaluated the wound healing and tissue response after placement of two different skin substitutes in subgingival mucosal pouches in rabbits. MATERIALS AND METHODS: Four rabbits were selected to receive a commercially available skin substitute consisting of a collagen matrix with fibroblasts and an epithelial layer (test membrane 1) and a prototype device consisting of a collagen matrix with fibroblasts only (test membrane 2). In each rabbit, two horizontal incisions were made in the buccal alveolar mucosa of the maxilla bilaterally to create submucosal pouches. Three pouches in each animal were filled with either the test 1 or test 2 membranes, and one pouch was left without a membrane (sham-operated control). All rabbits were sacrificed after a healing period of 4 weeks, and histologic samples were prepared and examined. RESULTS: After a healing period of 1 month, both tested membranes were still visible in the sections. Test membrane 1 was still bilayered, contained inflammatory cells in its center, and was encapsulated by a thick fibrous tissue. Numerous ectopic calcifications were evident in the collagenous part of the membrane and in association with some basal epithelial cells. Test membrane 2 was also encapsulated in fibrous tissue, with inflammatory cells present only between the fibrous encapsulation and the remnants of the membrane. For test membrane 2, no calcifications were visible. CONCLUSIONS: Test membrane 1 seemed to be more resistant to degradation, but there was also a more pronounced inflammatory reaction in comparison to test membrane 2, especially in the vicinity of the keratinocytes. The significance of the ectopic calcifications, along with that of the resorption or degradation processes of both tested membranes, must be evaluated in future experimental studies, with different time points after implantation examine
