1. Robotic-assisted nephrectomy with level II IVC thrombectomy using Rummel Tourniquets
ABSTRACT Background: Inferior vena cava (IVC) invasion from renal cell carcinoma (RCC) occurs at a rate of 4-10% (1). IVC thrombectomy (IVC-TE) can be an open procedure because of the need for handling of the IVC (2). The first reported series of robotic management of IVC-TE started in 2011 for the management of Level I - II thrombi with subsequent case rep

2. Percutaneous and endoscopic combined treatment of bladder and renal lithiasis in mitrofanoff conduit
ABSTRACT Introduction and Objectives: Treatment of bulky lithiasis in continent and non-continent urine storage reservoirs has been widely described and debated (1). Less is known about the optimal treatment in patients with a Mitrofanoff conduit. If voiding in these patients is incomplete, leading to recurrent symptomatic bacteriuria, formation of large li

4. Fibrin biopolymer as scaffold candidate to treat bone defects in rats
ABSTRACT Background: Bone tissue repair remains a challenge in tissue engineering. Currently, new materials are being applied and often integrated with live cells and biological scaffolds. The fibrin biopolymer (FBP) proposed in this study has hemostatic, sealant, adhesive, scaffolding and drug-delivery properties. The regenerative potential of an associat

5. Microbial quality and prevalence of foodborne pathogens of cheeses commercialized at different retail points in Mexico
Abstract Microbial quality and the prevalence of foodborne pathogens (E. coli 0157:H7, Salmonella spp., Listeria monocytogenes and Campylobacter jejuni) of cheeses sold at three retail points (supermarkets [SM], street markets [ST], and convenience grocery stores [CGS]) in Chihuahua, Mexico, were evaluated (n=90). The most commonly found cheeses in the retai

6. Effects of using chemical admixture with nanosilica in the consistency and mechanical strength of concrete
Resumo O desempenho do concreto depende do seu comportamento nos estados fresco e endurecido, haja vista que a trabalhabilidade corrobora para os processos de transporte e aplicação do material, enquanto a resistência mecânica garante eficácia e funcionalidade estrutural. Geralmente, estudos de misturas com nanosílica (nS) são voltados para análise d

7. Exposição ocupacional ao mercúrio em cooperativas de triagem de materiais recicláveis da região metropolitana de São Paulo, SP, Brasil
Resumo A exposição ocupacional ao mercúrio (Hg) foi avaliada em 4 cooperativas de materiais recicláveis por meio de amostragens de ar em 9 áreas (monte de triagem, balança, prensa, sala de resíduos de equipamentos eletroeletrônicos-REEE, refeitório, escritório, empilhadeira, esteira e pátio externo). Das 83 amostras, apenas 14,5% apresentaram conc

8. Efectos del uso de electrolitos soportes en ensayos electroquímicos de la aleación Al-4%Mg expuesta a bioetanol combustible
ABSTRACT The growth of world energy demand directly affects the consumption of petroleum-based fuels, increasing the negative impact of the use of these fuels and the decrease of crude oil reserves. This creates an opportunity for the use of fuels that are more efficient, of low environmental impact and, above all, of a renewable nature. Bioethanol is a biof

11. Production of polymeric nanofibers with different conditions of the electrospinning process
ABSTRACT Nanofibers are materials that present high elasticity, strength, porosity and surface-area-to-volume ratio. The electrospinning method is the most widely adopted technique for forming polymeric nanofibers due to repeatability, easy scale-up process and production of long and continuous nanofibers. This method produces nanofibers with diameters rangi

12. Qualification of Magnesium/Teflon/Viton Pyrotechnic Composition Used in Rocket Motors Ignition System
ABSTRACT The application of fluoropolymers in highenergy-release pyrotechnic compositions is common in the space and defense areas. Pyrotechnic compositions of magnesium/Teflon/Viton are widely used in military flares and pyrogen igniters for igniting the solid propellant of a rocket motor. Pyrotechnic components are considered highrisk products as they may
