Em 2001, o Instituto Superior de Ciências Aplicadas (ISCA Faculdades de Limeira) iniciou um projeto pelo qual o Observatório do Morro Azul empreendeu uma parceria com o Centro de Promoção Social Municipal (CEPROSOM), instituição mantida pela Prefeitura Municipal de Limeira para atender crianças e adolescentes carentes. O CEPROSOM contava com dois projetos: Projeto Centro de Convivência Infantil (CCI) e Programa Criança e Adolescente (PCA), que atendiam crianças e adolescentes em Centros Comunitários de diversas áreas da cidade. Esses projetos têm como prioridades estabelecer atividades prazerosas para as crianças no sentido de retirá-las das ruas. Assim sendo, as crianças passaram a ter mais um tipo de atividade - as visitas ao observatório. Este painel descreve as várias fases do projeto, que envolveu: reuniões de planejamento, curso de Astronomia para as orientadoras dos CCIs e PCAs, atividades relacionadas a visitas das crianças ao Observatório, proposta de construção de gnômons e relógios de Sol nos diversos Centros Comunitários de Limeira e divulgação do projeto na imprensa. O painel inclui discussões sobre a aprendizagem de crianças carentes, relatos que mostram a postura das orientadoras sobre a pertinência do ensino de Astronomia, relatos do monitor que fez o atendimento no Observatório e o que o número de crianças atendidas representou para as atividades da instituição desde o inÃcio de suas atividades e, em particular, em 2001. Os resultados são baseados na análise de relatos das orientadoras e do monitor do Observatório, registros de visitas e matérias da imprensa local. Conclui com uma avaliação do que tal projeto representou para as Instituições participantes. Para o Observatório, em particular, foi feita uma análise com relação Ãs outras modalidades de atendimentos que envolvem alunos de escolas e público em geral. Também é abordada a questão do compromisso social do Observatório na educação do

TandEM was proposed as an L-class (large) mission in response to ESAâs Cosmic Vision 2015â2025 Call, and accepted for further studies, with the goal of exploring Titan and Enceladus. The mission concept is to perform in situ investigations of two worlds tied together by location and properties, whose remarkable natures have been partly revealed by the ongoing CassiniâHuygens mission. These bodies still hold mysteries requiring a complete exploration using a variety of vehicles and instruments. TandEM is an ambitious mission because its targets are two of the most exciting and challenging bodies in the Solar System. It is designed to build on but exceed the scientific and technological accomplishments of the CassiniâHuygens mission, exploring Titan and Enceladus in ways that are not currently possible (full close-up and in situ coverage over long periods of time). In the current mission architecture, TandEM proposes to deliver two medium-sized spacecraft to the Saturnian system. One spacecraft would be an orbiter with a large host of instruments which would perform several Enceladus flybys and deliver penetrators to its surface before going into a dedicated orbit around Titan alone, while the other spacecraft would carry the Titan in situ investigation components, i.e. a hot-air balloon (Montgolfière) and possibly several landing probes to be delivered through the atmosphere.

1994-07-01
Because falls are common among the elderly and are associated with high morbidity and mortality, community surveillance has been recommended. The purpose of this study was to characterize the impact of falls among the elderly on emergency medical transport services (EMS) and to explore the potential for community surveillance of falls through the use of computerized EMS data. Computerized EMS data and United States census data for 1990 for persons aged > or = 65 in Forsyth County, NC, were used to produce EMS transport rates for falls and to make comparisons by age, gender, race, and residence (nursing home vs community). A fall was reported as the cause for EMS summons in 15.1% (613 of 4,058) of cases. Transport rates in 1990 for falls were 7.8 per 1,000, 25.4 per 1,000, and 58.5 per 1,000 for the age groups of 65 to 74 years, 75 to 84 years, and 85 years and older. Rates were higher for females than for males (17.1 per 1,000 v 8.1 per 1,000) and higher for whites than for African-Americans (14.3 per 1,000 v 10.3 per 1,000). Rates for nursing home residents were four times that of community residents (70.6 per 1,000 v 16.0 per 1,000). Over 50% of nursing home fallers were transported between midnight and 0400 compared with 25% of community dwellers. EMS summons for older adults reporting a fall accounts for a significant portion (15%) of all transports in this county. Computerized EMS data demonstrated patterns of falls among the elderly that are consistent with known demographic factors. The potential for using computerized EMS data as a practical means of community surveillance should be further explored.

Estudamos o ambiente de galáxias com formação estelar inicialmente a partir de uma amostra limitada em volume proveniente do 2dF Galaxy Redshift Survey. Discriminamos as galáxias com formação estelar com base em distintas classes espectrais, utilizando para esta classificação as larguras equivalentes das linhas [OII]l3727 e Hd. O ambiente é caracterizado pela densidade espacial local de galáxias. Mostramos que a fração de galáxias com formação estelar é bastante reduzida em ambientes densos, enquanto a de galáxias passivas aumenta nestas regiões. Por outro lado, quando analisamos a fração de galáxias que apresentam um surto recente de formação estelar, notamos que ela independe do ambiente, sendo que em regiões mais densas alguns destes objetos apresentam distorções em sua morfologia. Estes resultados são confrontados com a análise da dependência ambiental da taxa de formação estelar, estimada pela emissão em Ha, de uma amostra extraÃda do Sloan Digital Sky Survey. Um declÃnio gradual da formação estelar também é observado nesta análise, sugerindo que as interações por efeitos de maré sejam responsáveis pela redução da formação estelar em ambientes densos através da remoção do reservatório de gás das galáxias. No entanto, estas interações também podem induzir surtos de formação estelar nas galáxias, além de peculiaridades morfológicas observadas nos objetos que habitam regiões mais densas.

To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein. Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies. In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients. Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others.

Helicopter EMS: Research Endpoints and Potential Benefits
Thomas, Stephen H.; Arthur, Annette O.
2012-01-01
Patients, EMS systems, and healthcare regions benefit from Helicopter EMS (HEMS) utilization. This article discusses these benefits in terms of specific endpoints utilized in research projects. The endpoint of interest, be it primary, secondary, or surrogate, is important to understand in the deployment of HEMS resources or in planning further HEMS outcomes research. The most important outcomes are those which show potential benefits to the patients, such as functional survival, pain relief, and earlier ALS care. Case reports are also important âoutcomesâ publications. The benefits of HEMS in the rural setting is the ability to provide timely access to Level I or Level II trauma centers and in nontrauma, interfacility transport of cardiac, stroke, and even sepsis patients. Many HEMS crews have pharmacologic and procedural capabilities that bring a different level of care to a trauma scene or small referring hospital, especially in the rural setting. Regional healthcare and EMS system's benefit from HEMS by their capability to extend the advanced level of care throughout a region, provide a âbackupâ for areas with limited ALS coverage, minimize transport times, make available direct transport to specialized centers, and offer flexibility of transport in overloaded hospital systems.

The effective molarity (EM)--a computational approach.
Karaman, Rafik
2010-08-01
The effective molarity (EM) for 12 intramolecular S(N)2 processes involving the formation of substituted aziridines and substituted epoxides were computed using ab initio and DFT calculation methods. Strong correlation was found between the calculated effective molarity and the experimentally determined values. This result could open a door for obtaining EM values for intramolecular processes that are difficult to be experimentally provided. Furthermore, the calculation results reveal that the driving forces for ring-closing reactions in the two different systems are proximity orientation of the nucleophile to the electrophile and the ground strain energies of the products and the reactants.

to assess the incidence of pediatric vascular injuries in patients treated at the Emergency Room of the Eastern Children's Hospital, in Manaus. we conducted a retrospective study of pediatric patients who suffered vascular injuries treated between February 2001 to February 2012. we studied 71 patients, predominantly male (78.87%), with a mean age of 7.63 years. The predominant mechanism of injury was stab wound in 27 patients (38.03%). The average hospital stay was 10.18 days; 16 patients required care in intensive care unit, with average stay of 8.81 days. The main injuries occurred in the extremities, the upper limb being the most affected, with lesions of the ulnar artery in 13 (15.66%) and radial in 10 (12.04%). The mostly applied procedure was vascular exploration 35 (32.4%). Complications occurred in nine patients (12.68%). Mortality was 1.4%, in one patient with a lesion of the common iliac vein and the inferior vena cava due fall from height. pediatric vascular injury occurred predominantly in the extremities. The dimensions of the injured vessels made surgical correction more complex and increased complication rates, particularly amputations. avaliar a incidência de traumatismos vasculares pediátricos em doentes atendidos no Hospital Pronto Socorro da Criança Zona Leste, na cidade de Manaus. estudo retrospectivo de doentes pediátricos vÃtimas de traumatismos vasculares atendidos no perÃodo de fevereiro de 2001 a fevereiro de 2012. foram estudados 71 doentes com predominância do sexo masculino (78,87%) com média de idade de 7,63 anos.

To determine the accuracy of emergency medical services (EMS) provider assessments of motor vehicle damage when compared with measurements made by a professional crash reconstructionist. EMS providers caring for adult patients injured during a motor vehicle crash and transported to the regional trauma center in a midsized community were interviewed upon emergency department arrival. The interview collected provider estimates of crash mechanism of injury. For crashes that met a preset severity threshold, the vehicle's owner was asked to consent to having a crash reconstructionist assess the vehicle. The assessment included measuring intrusion and external automobile deformity. Vehicle damage was used to calculate change in velocity. Paired t-test, correlation, and kappa were used to compare EMS estimates and investigator-derived values. Ninety-one vehicles were enrolled; of these, 58 were inspected and 33 were excluded because the vehicle was not accessible. Six vehicles had multiple patients. Therefore, a total of 68 EMS estimates were compared with the inspection findings. Patients were 46% male, 28% were admitted to hospital, and 1% died. The mean EMS-estimated deformity was 18 inches and the mean measured deformity was 14 inches. The mean EMS-estimated intrusion was 5 inches and the mean measured intrusion was 4 inches. The EMS providers and the reconstructionist had 68% agreement for determination of external automobile deformity (kappa 0.26) and 88% agreement for determination of intrusion (kappa 0.27) when the 1999 American College of Surgeons Field Triage Decision Scheme criteria were applied. The mean (± standard deviation) EMS-estimated speed prior to the crash was 48 ± 13 mph and the mean reconstructionist-estimated change in velocity was 18 ± 12 mph (correlation -0.45). The EMS providers determined that 19 vehicles had rolled over, whereas the investigator identified 18 (kappa 0.96). In 55 cases, EMS and the investigator agreed on seat belt use; for

X-rays in the Cryo-EM Era: Structural Biologyâs Dynamic Future
Shoemaker, Susannah C.; Ando, Nozomi
2018-01-01
Over the past several years, single-particle cryo-electron microscopy (cryo-EM) has emerged as a leading method for elucidating macromolecular structures at near-atomic resolution, rivaling even the established technique of X-ray crystallography. Cryo-EM is now able to probe proteins as small as hemoglobin (64 kDa), while avoiding the crystallization bottleneck entirely. The remarkable success of cryo-EM has called into question the continuing relevance of X-ray methods, particularly crystallography. To say that the future of structural biology is either cryo-EM or crystallography, however, would be misguided. Crystallography remains better suited to yield precise atomic coordinates of macromolecules under a few hundred kDa in size, while the ability to probe larger, potentially more disordered assemblies is a distinct advantage of cryo-EM. Likewise, crystallography is better equipped to provide high-resolution dynamic information as a function of time, temperature, pressure, and other perturbations, whereas cryo-EM offers increasing insight into conformational and energy landscapes, particularly as algorithms to deconvolute conformational heterogeneity become more advanced. Ultimately, the future of both techniques depends on how their individual strengths are utilized to tackle questions on the frontiers of structural biology. Structure determination is just one piece of a much larger puzzle: a central challenge of modern structural biology is to relate structural information to biological function. In this perspective, we share insight from several leaders in the field and examine the unique and complementary ways in which X-ray methods and cryo-EM can shape the future of structural biology.

Eimeria maxima 14-3-3 (Em14-3-3) open reading frame (ORF) which consisted of 861 bp encoding a protein of 286 amino acids was successfully amplified and sequenced. Subsequently, the Em14-3-3 ORF was subcloned into pET-32a (+) and pVAX1, respectively. RT-PCR and immunoblot analyses confirmed that the target gene was successfully transcribed and expressed in vivo. Immunofluorescence analysis showed that Em14-3-3 was expressed in both the sporozoites and merozoites. The animal experiments demonstrated that both rEm14-3-3 and pVAX1-14-3-3 could clearly alleviate jejunum lesions and body weight loss. The Em14-3-3 vaccines could increase oocyst decrease ratio, as well as produce an anticoccidial index of more than 165. The percentages of CD4 + in both the Em14-3-3 immunized groups were much higher, when compared with those of PBS, pET32a (+), and pVAX1 controls (Pâ¯<â¯0.05). Similarly, the anti-Em14-3-3 antibody titers of both rEm14-3-3 and pVAX1-14-3-3 immunized groups showed higher levels compared with those of PBS, pET32a (+), and pVAX1 controls (Pâ¯<â¯0.05). The IFN-γ and tumor growth factor-β (TGF-β) levels showed signiï¬cant increments in the rEm14-3-3 and pVAX1-14-3-3 immunized groups, when compared with those in the negative controls (Pâ¯<â¯0.05). These results demonstrated that Em14-3-3 could be used as a promising antigen candidate for developing vaccines against E. maxima. Copyright © 2018 Elsevier B.V. All rights reserved.

In patients with severe respiratory failure, either hypoxemic or hypercapnic, life support with mechanical ventilation alone can be insufficient to meet their needs, especially if one tries to avoid ventilator settings that can cause injury to the lungs. In those patients, extracorporeal membrane oxygenation (ECMO), which is also very effective in removing carbon dioxide from the blood, can provide life support, allowing the application of protective lung ventilation. In this review article, we aim to explore some of the most relevant aspects of using ECMO for respiratory support. We discuss the history of respiratory support using ECMO in adults, as well as the clinical evidence; costs; indications; installation of the equipment; ventilator settings; daily care of the patient and the system; common troubleshooting; weaning; and discontinuation. RESUMO Em pacientes com insuficiência respiratória grave (hipoxêmica ou hipercápnica), o suporte somente com ventilação mecânica pode ser insuficiente para suas necessidades, especialmente quando se tenta evitar o uso de parâmetros ventilatórios que possam causar danos aos pulmões. Nesses pacientes, extracorporeal membrane oxygenation (ECMO, oxigenação extracorpórea por membrana), que também é muito eficaz na remoção de dióxido de carbono do sangue, pode manter a vida, permitindo o uso de ventilação pulmonar protetora. No presente artigo de revisão, objetivamos explorar alguns dos aspectos mais relevantes do suporte respiratório por ECMO. Discutimos a história do suporte respiratório por ECMO em adultos; evidências clÃnicas; custos; indicações; instalação do equipamento; parâmetros ventilatórios; cuidado diário do paciente e do sistema; solução de problemas comuns; desmame e descontinuação.

Kidney transplants with expanded criteria donor have been associated with improved patient survival compared to those who remain on dialysis. To compare renal function and survival of the kidney graft of deceased donor with expanded criteria and standard criteria over a year in a single transplant center. 255 kidney transplant recipients with deceased donor were included in the study between the years 2011 to 2013 and they were separated into two groups according to the type of donor (expanded criteria donor - ECD - and standard criteria donor - SCD). 231 deceased donor transplants (90.6%) were performed with standard criteria donor (SCD) and 24 (9.4%) with expanded criteria donor (ECD). There was no difference in the prevalence of delayed graft function - DGF - (62.9% vs. 70.8%; p = 0.44). Expanded criteria donor group had lower glomerular filtration rate (GFR) at the end of the 1st year (56.8 ± 26.9 vs. 76.9 ± 23.7; p = 0.001). Patient survival was significantly lower in the ECD group, but the graft survival was not different after death-censored analysis. The ECD group was associated with significantly lower levels of GFR during the first year of transplant and a lower patient survival at the 1st year when compared to the SCD. A aceitação dos rins com critério expandido de doação tem sido associada com melhor sobrevida do paciente em comparação Ãqueles que permanecem em terapia dialÃtica. Comparar a função renal e a sobrevida do enxerto renal de doador falecido critério expandido com os de doador falecido critério padrão ao longo de um ano em um único centro de transplantes. Foram incluÃdos 255 receptores de transplante renal com doador falecido, realizados entre os anos de 2011 a 2013, sendo divididos em dois grupos segundo o tipo de doador (critério expandido - DCE - ou padrão -DCP). Foram avaliados 231 receptores com doador critério ideal (90,6%) e 24 com doador critério expandido (9,4%). Não houve diferença na prevalência de fun
An Evaluation of DOE-EM Public Participation Programs

This report evaluates the scope and effectiveness of the public participation pr ograms, including Site-Specific Advisory Boards (SSABs), at seven U.S. Departmen t of Energy (DOE) sites: Fernald, Hanford, Los Alamos, Nevada, Oak Ridge, Paduc ah, and Savannah River. The primary purpose of the study is to assist both DOE Field and Headquarters managers in reviewing and understanding lessons learned o ver the past decade concerning public participation programs administered by the DOE Office of Environmental Management (EM). The evaluation provides a snapsh ot of selected EM public participation programs at a particular point of time. It is based onmore» interviews and site visits conducted between January and June 200 2- a time of change within the program. The study focuses on public participati on programs that incorporate a variety of activities and address a wide range of individual site activities and decisions. It uses the Acceptability Diamond as an evaluative framework to answer questions about stakeholders' experiences wit h, and assessment of, DOE-EM's public participation programs. The Acceptability Diamond, which was developed by researchers from the Pacific Northwest National Laboratory in previous research, identifies four program dimensions - substanti ve issues, decision-making process, relationships, and accountability - that det ermine the effectiveness of an agency's interactions with local communities. Es sentially, a public participation program may be deemed effective to the extent that it provides for open disclosure and addresses all four acceptability dimens ions in ways that are appropriate and effective for a particular community and s ituation. This framework provides a guide for agencies to 1) set objectives, 2) design public participation and oversight programs, and 3) set criteria for eva luating program effectiveness. In the current study, where the framework is use d as a means of assessing program effectiveness, the focus is on
