Obtenção minimamente invasiva de veia safena para cirurgia de revascularização do miocárdio

OBJETIVO: Analisar, comparativamente, a obtenção minimamente invasiva com o uso do MINI-HARVEST® e com instrumental tradicional adaptado. MÉTODO: de junho de 1996 a janeiro de 1999, 63 pacientes submetidos à cirurgia de revascularização do miocárdio tiveram suas veias safenas retiradas segundo técnica minimamente invasiva. Nos 30 primeiros pacientes da série utilizou-se método de visão direta com auxílio de dois afastadores de Langenbeck, e nos 33 restantes utilizou-se o MINI-HARVEST®. RESULTADOS: A idade média dos pacientes era de 61 ± 8,75 anos, sendo 52 homens e 11 mulheres. Quarenta e cinco pacientes eram diabéticos, 45 apresentavam sobrepeso/obesidade, 25 eram tabagistas ativos, 32 apresentavam história pregressa de infarto do miocárdio. O tempo médio de retirada da veia safena com afastadores Langenbeck foi de 34,2 ± 8,14 minutos e com o MINI-HARVEST® de 39,20 ± 9,12 minutos. A extensão de veia retirada foi similar nos dois grupos, variando de 10 a 30 cm. Houve uma deiscência superficial no grupo com afastadores de Langenbeck. Houve necessidade de reversão para método tradicional de retirada em dois casos do grupo MINI-HARVEST® e um do grupo Langenbeck. A incidência de infarto transoperatório foi 4,5% (três) no grupo Langenbeck e 3,1%(dois) no grupo MINI-HARVEST®. CONCLUSÕES: Podemos concluir que o método de obtenção de veia safena minimamente invasivo sob visão direta é efetivo e seguro, tanto com o uso de instrumentos tradicionais adaptados para este fim, como com afastadores especialmente constituídos, ressaltando-se que o MINI-HARVEST® dispensa a presença de um auxiliar.

Modeling, design and experimental characterization of Micro-Electro-Mechanical-Systems for gas chromatographic applications

Design parameters, process flows, electro-thermal-fluidic simulations and experimental characterizations of Micro-Electro-Mechanical-Systems (MEMS) suited for gas-chromatographic (GC) applications are presented and thoroughly described in this thesis, whose topic belongs to the research activities the Institute for Microelectronics and Microsystems (IMM)-Bologna is involved since several years, i.e. the development of micro-systems for chemical analysis, based on silicon micro-machining techniques and able to perform analysis of complex gaseous mixtures, especially in the field of environmental monitoring. In this regard, attention has been focused on the development of micro-fabricated devices to be employed in a portable mini-GC system for the analysis of aromatic Volatile Organic Compounds (VOC) like Benzene, Toluene, Ethyl-benzene and Xylene (BTEX), i.e. chemical compounds which can significantly affect environment and human health because of their demonstrated carcinogenicity (benzene) or toxicity (toluene, xylene) even at parts per billion (ppb) concentrations. The most significant results achieved through the laboratory functional characterization of the mini-GC system have been reported, together with in-field analysis results carried out in a station of the Bologna air monitoring network and compared with those provided by a commercial GC system. The development of more advanced prototypes of micro-fabricated devices specifically suited for FAST-GC have been also presented (silicon capillary columns, Ultra-Low-Power (ULP) Metal OXide (MOX) sensor, Thermal Conductivity Detector (TCD)), together with the technological processes for their fabrication. The experimentally demonstrated very high sensitivity of ULP-MOX sensors to VOCs, coupled with the extremely low power consumption, makes the developed ULP-MOX sensor the most performing metal oxide sensor reported up to now in literature, while preliminary test results proved that the developed silicon capillary columns are capable of performances comparable to those of the best fused silica capillary columns. Finally, the development and the validation of a coupled electro-thermal Finite Element Model suited for both steady-state and transient analysis of the micro-devices has been described, and subsequently implemented with a fluidic part to investigate devices behaviour in presence of a gas flowing with certain volumetric flow rates.

Spatial Decision Support System for Assessing Micro, Mini and Small Hydel Potential

This study describes the design and implementation of DSS for assessment of Mini, Micro and Small Schemes. The design links a set of modelling, manipulation, spatial analyses and display tools to a structured database that has the facility to store both observed and simulated data. The main hypothesis is that this tool can be used to form a core of practical methodology that will result in more resilient in less time and can be used by decision-making bodies to assess the impacts of various scenarios (e.g.: changes in land use pattern) and to review, cost and benefits of decisions to be made. It also offers means of entering, accessing and interpreting the information for the purpose of sound decision making. Thus, the overall objective of this DSS is the development of set of tools aimed at transforming data into information and aid decisions at different scales.

Development of Mini Space Bioreactor System

微重力对空间细胞培养的影响规律一直是国际空间生物学的重点研究领域。而空间细胞培养技术和方法作为空间细胞生物学研究的基础，其概念性和原理性设计是正确区分重力对细胞的直接作用和间接作用的前提。另外，空间实验成本高昂，空间细胞培养装置的体积、重量、功耗是首要的制约因素。为保证充分物质交换，满足细胞代谢需求，同时尽可能降低由细胞供液形式产生的力学环境对细胞的影响，区分重力对细胞的直接作用和间接作用，我们研制了逆流片层式微型细胞培养装置。实验表明为使培养液流动对细胞生长影响最小，流动剪切应变率应小于1s-1。通过理论计算分析的逆流片层式微型细胞培养装培养室内流场及流动剪切范围表明，该装置可以满足要求。通过实验检测细胞培养时的氧耗、糖耗等，可以确定不同种类细胞的培养液流量范围。培养室内采用经表面改性的聚合物网架作为细胞载体，使得培养空间得到充分利用，并利于操作。从而为空间细胞培养研究提供了一种新的技术手段。

The 26S proteasome system degrades the ERM transcription factor and regulates its transcription-enhancing activity

ERM is a member of the ETS transcription factor family. High levels of the corresponding mRNA are detected in a variety of human breast cancer cell lines, as well as in aggressive human breast tumors. As ERM protein is almost undetectable in these cells, high degradation of this transcription factor has been postulated. Here we have investigated whether ERM degradation might depend on the proteasome pathway. We show that endogenous and ectopically expressed ERM protein is short-lived protein and undergoes proteasome-dependent degradation. Deletion mutagenesis studies indicate that the 61 C-terminal amino acids of ERM are critical for its proteolysis and serve as a degradation signal. Although ERM conjugates with ubiquitin, this post-translational modification does not depend on the C-terminal domain. We have used an Ets-responsive ICAM-1 reporter plasmid to show that the ubiquitin-proteasome pathway can affect transcriptional function of ERM. Thus, ERM is subject to degradation via the 26S proteasome pathway, and this pathway probably plays an important role in regulating ERM transcriptional activity. © 2007 Nature Publishing Group.

Plant density in production of mini lettuce cultivars in organic system management

Production of mini vegetables in organic system is a good alternative to improve profit, but there are no researches about the optimum plant density for these cultivars in Brazilian conditions. Two experiments were conducted to evaluate the production of mini lettuce cultivars in different plant densities. Experiment 1 was conducted from January 1th (sowing) to February 10th (harvesting), 2012. The experimental design was completely randomized blocks, with six treatments in factorial scheme, 3 mini lettuce cultivars (Tudela, Renoir and Sartre) x 2 spacing between plants (16 and 20 cm), with eight replications and plots (2.04 m(2)) with six rows, spaced 15 cm. Experiment 2 was conducted from June 6th (sowing) to July 18th (harvesting), 2012. The cultivars Sartre and Renoir were evaluated under four plant densities (444,444; 333,333; 266,667 and 200,000 plants ha(-1), corresponding to spacing of 15x15, 15x20, 25x15 and 25x20 cm, respectively). Eight treatments were defined by a factorial scheme 2 (cultivars) x 4 (plant densities) and arranged in a completely randomized block design, with nine replications and plots with 2.04 m2. The evaluated characteristics in both experiments were total and marketable fresh weight per plant, plant dry weight, plant diameter and height, marketable yield and discard percentage. In first experiment, during the summer, cultivar Sartre showed the highest marketable fresh weight (72 g plant(-1)). Heaviest plants (91.6 g plant(-1)) were obtained with the higher plant spacing, but the highest yield (2.51 kg m(-2)) was obtained with the smaller spacing. In winter, plants with higher total (190 g plant(-1)) and marketable (146 g planta(-1)) fresh weight were obtained with cultivar Sartre, and the same was observed in low plant density. However, the higher plant density, the higher the yield.

Towards a ground navigation system based in visual feedback provided by a mini UAV

This paper addresses initial efforts to develop a navigation system for ground vehicles supported by visual feedback from a mini aerial vehicle. A visual-based algorithm computes the ground vehicle pose in the world frame, as well as possible obstacles within the ground vehicle pathway. Relying on that information, a navigation and obstacle avoidance system is used to re-plan the ground vehicle trajectory, ensuring an optimal detour. Finally, some experiments are presented employing a unmanned ground vehicle (UGV) and a low cost mini unmanned aerial vehicle (UAV).

Simulation of AC, DC, and AC-DC coupled mini-grids. In search of the most efficient system

Renewable energy hybrid systems and mini-grids for electrification of rural areas are known to be reliable and more cost efficient than grid extension or only-diesel based systems. However, there is still some uncertainty in some areas, for example, which is the most efficient way of coupling hybrid systems: AC, DC or AC-DC? With the use of Matlab/Simulink a mini-grid that connects a school, a small hospital and an ecotourism hostel has been modelled. This same mini grid has been coupled in the different possible ways and the system’s efficiency has been studied. In addition, while keeping the consumption constant, the generation sources and the consumption profile have been modified and the effect on the efficiency under each configuration has also been analysed. Finally different weather profiles have been introduced and, again, the effect on the efficiency of each system has been observed.
