Computational simulation applied in choosing the best solution in a product development using design for manufacturing and assembly approach

Highlights: The product development methodology aims to assist the planning and design of the product throughout its life cycle. Using selection criteria it is possible to choose a solution will be followed until the end of the development process and this process is known as optimization of product solutions. Design for Manufacturing and Assembly (DFMA) is an approach that allows selecting a product solution with better manufacturing and assembly performance. Computational modeling allows representing systems in virtual environment in order to reproduce its characteristics and to compare scenarios through simulation. Goal: The objective of this work was to apply the computer simulation to compare the productive performance, according to production times, productivity and resource utilization rate, of three solutions proposed for a raincoat for pets with thermal protection. Methodology: Initially, conceptual models representing the production systems for the three product solutions were generated. The systems were modeled in discrete event simulation software, enabling different scenarios testing, resulting in production performance indicators for each product solution. Results: The analysis of the performance indicators allow identifying that the third solution proposed for the product obtained the best productive performance in all proposed scenarios; therefore, it was chosen as the best solution for the product according to the DFMA approach. Limitations of the investigation: The application of the methodology indicated in this work was limited to the study of a single productive system of a specific product. Practical implications: This work presents a practical application of computer simulation tools applied to product development. Originality / Value: The original contribution of this work is the application of computational simulation of production systems in product development following the DFMA approach

METHODS: "In vitro" tests with antibiogram discs and biofilm formers bacteria antibiothic action from Ca(OH)2 and tergentol solutions and the 0,12% clorhexydine digluconate as "gold-standard". RESULTS: The results were analyzed using the Kruskal-Wallis test and Dunn´s multiple comparison post-test with p-value always lower than 0,05. The clorhexydine showed a better antimibrobian action in correlation with Ca(OH)2 and tergentol solutions. The statistical differences among clorhexydine and this study other solutions was not significant in a greater part of comparisons. CONCLUSIONS: The 0,12% clorhexydine digluconate was the most effective antibiotic agent in this research. Ca(OH)2 and tergentol solutions does not demonstrate satisfactory effectiveness in correlation the clorhexydine, mainly, for the Streptococcus mutans. More complete studies are necessary for CHD 20 evaluation as an oral antiseptic.OBJETIVOS: Este estudo realizado no departamento de Odontologia da Universidade Federal do Rio Grande do Norte foi idealizado com propósito de pesquisar a ação "in vitro" de soluções a base de Ca(OH)2 e tergentol frente a bactérias colonizadoras da cavidade bucal e cariogênicas visando contribuir para o estudo sobre os agentes químicos para controle do biofilme dental. MÉTODOS: Testou-se através de discos de antibiograma e ação em bactérias formadoras de biofilme a ação antimicrobiana de algumas soluções de Ca(OH)2 e tergentol usando-se como padrão-ouro o digluconato de clorexidina a 0,12%. RESULTADOS: Os resultados foram analisados através do teste de Kruskal-Wallis e do pós-teste de comparação múltipla de Dunn com valores de p sempre menores que 0,05. A clorexidina obteve melhores resultados em nível de ação antimicrobiana em relação às soluções a base de Ca(OH)2 e tergentol. A diferença estatísta da ação da clorexidina frente às demais soluções e aos tipos bacterianos testados não foi significativa para a maiorias dos cruzamentos. CONCLUSÕES: O digluconato de clorexidina a 0,12% foi o egente antimicrobiano mais efetivo neste estudo. As soluções a base de hidróxido de cálcio não apresentaram efetividade satisfatória em relação a clorexidina, principalmente em relação ao Streptococcus mutans.

Photobiomodulation Therapy in the Proliferation and Differentiation of Human Umbilical Cord Mesenchymal Stem Cells: An In Vitro Study

Introduction: Since photobiomodulation therapy (PBMT) favors in vitro mesenchymal stem cell (MSC) preconditioning before MSC transplantation, increasing the proliferation of these cells without molecular injuries by conserving their characteristics, in the present in vitro study we analyzed the effect of PBMT on the proliferation and osteogenic differentiation of human umbilical cord mesenchymal stem cells (hUCMSCs).Methods: Irradiation with an InGaAIP Laser (660 nm, 10 mW, 2.5 J/cm2, 0.08 cm2 spot size, and 10 s) was carried out. The cells were divided into four groups: CONTROL [cells grown in Dulbecco’s Modified Eagle Medium (DMEM)], OSTEO (cells grown in an osteogenic medium); PBMT (cells grown in DMEM+PBMT), and OSTEO+PBMT (cells grown in an osteogenic medium-plus PBMT). The cell proliferation curve was obtained over periods of 24, 48 and 72 hours using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. Osteogenic differentiation was analyzed by the formation of calcium nodules over periods of 7, 14 and 21 days. Morphometric analysis was performed to quantify the total area of nodular calcification.Results: The highest cell proliferation and cell differentiation occurred in the OSTEO+PBMT group, followed by the PBMT, OSTEO, and CONTROL groups respectively, at the observed times (P < 0.05).Conclusion: PBMT enhanced the osteogenic proliferation and the differentiation of hUCMSCs during the periods tested, without causing damage to the cells and preserving their specific characteristics, a fact that may represent an innovative pretreatment in the application of stem cells

Diaphragmatic pacing stimulation in spinal cord injury: anesthetic and perioperative management

OBJECTIVE: The standard therapy for patients with high-level spinal cord injury is long-term mechanical ventilation through a tracheostomy. However, in some cases, this approach results in death or disability. The aim of this study is to highlight the anesthetics and perioperative aspects of patients undergoing insertion of a diaphragmatic pacemaker. METHODS: Five patients with quadriplegia following high cervical traumatic spinal cord injury and ventilator-dependent chronic respiratory failure were implanted with a laparoscopic diaphragmatic pacemaker after preoperative assessments of their phrenic nerve function and diaphragm contractility through transcutaneous nerve stimulation. ClinicalTrials.gov: NCT01385384. RESULTS: The diaphragmatic pacemaker placement was successful in all of the patients. Two patients presented with capnothorax during the perioperative period, which resolved without consequences. After six months, three patients achieved continuous use of the diaphragm pacing system, and one patient could be removed from mechanical ventilation for more than 4 hours per day. CONCLUSIONS: The implantation of a diaphragmatic phrenic system is a new and safe technique with potential to improve the quality of life of patients who are dependent on mechanical ventilation because of spinal cord injuries. Appropriate indication and adequate perioperative care are fundamental to achieving better results
