1. Rapamycin and Paclitaxel Affect Human Aortic Smooth Muscle Cells-Derived Foam Cells Viability and Proliferation
Abstract Introduction: Drug-eluting stents (DES) coated with rapamycin or paclitaxel as antiproliferative substances significantly reduced the incidence of clinical restenosis and had fewer side effects after percutaneous coronary intervention. However, DES coated with rapamycin or paclitaxel still cause restenosis due to abnormal tissue growth which remain

2. Role of Urotensin-II in Saphenous Vein Graft Disease
Abstract Objective: To elucidate the effect of diabetes mellitus (DM) on the atherosclerotic process in saphenous vein grafts by determining urotensin-II (U-II) levels in harvested saphenous veins of patients who underwent coronary artery bypass grafting (CABG). Methods: Coronary artery disease (CAD) patients who underwent CABG were divided into two groups

4. Biodegradation of cypermethrin by immobilized cells of
Micrococcus sp. strain CPN 1Pyrethroid pesticide cypermethrin is a environmental pollutant because of its widespread use, toxicity and persistence. Biodegradation of such chemicals by microorganisms may provide an cost-effective method for their detoxification. We have investigated the degradation of cypermethrin by immobilized cells of

5. Studying energy absorption in tapered thick walled tubes
In many engineering structures different energy absorption systems may be used to improve crashworthiness capability of the system and to control damages that may occur in a system during an accident. Therefore, extensive research has been done on the energy-absorbing cells. In this paper, energy absorption in tapered thick walled tubes has been investigated

6. Observations of the effects of different chemical blowing agents on the degradation of poly(lactic acid) foams in simulated soil
This work examined the influence of different chemical blowing agents (CBA), one endothermic and one exothermic, at the same concentration (2% by mass), on poly(acid lactic), PLA foams. The CBA was incorporated into the PLA in a single-screw extruder, and the foams were expanded by heating in an electric oven under free pressure conditions. Foam degradation

7. Enhancement of chitosanase production by cell immobilization of Gongronella sp. JG
Chitosanase production of Gongronella sp. JG cells immobilized in calcium alginate gel and polyurethane foam was compared with that of the free cells, there was a 60% increase in the enzyme yield (2429 U/L) compared to the highest yield obtained from free cells (1513 U/L). The optimal immobilization parameters (concentrations of sodium alginate, calcium chlo

8. Fabricación y caracterización de espumas de alúmina para aplicación en quemadores porosos radiantes
In radiant porous burners, the heat source requires a solid porous matrix where the combustion reaction takes place, in which the heat transfer is performed more efficiently. This work is based on a study of the alumina suspension rheology, where parameters as viscosity and tixotropy were the guide to select the appropriate formulation for the ceramic foam f

9. Neoaterosclerose precoce como causa de reestenose de stent farmacológico de segunda geração
Relatamos um caso de reestenose de stent eluidor de everolimus causada por neoaterogênese. A tomografia de coerência óptica revelou, no segmento médio intrastent, presença de arco superficial com alta intensidade óptica, seguido por significativa atenuação do sinal luminoso, com limites mal definidos, indicando presença de infiltração lipídica e/

10. Degradation of h-acid by free and immobilized cells of Alcaligenes latus
Alcaligenes latus, isolated from industrial effluent, was able to grow in mineral salts medium with 50 ppm (0.15 mM) of H-acid as a sole source of carbon. Immobilization of Alcaligenes latus in Ca-alginate and polyurethane foam resulted in cells embedded in the matrices. When free cells and immobilized cells were used for biodegradation studies at concentrat

11. Expressão de fragmentos variáveis de cadeia simples anti-LDL eletronegativa (scFv) em Pichia pastoris e seu efeito sobre a formação de células espumosas / Expression of anti-electronegative LDL single-chain fragment variable (scFv) in Pichia pastoris and its effect on foam cells formation
Os produtos de modificação de lipoproteínas de baixa densidade (LDL) como a subfração eletronegativa [LDL(-)] desempenham um importante papel na progressão da aterosclerose. O acúmulo massivo de LDL modificada captada por macrófagos resulta em células espumosas que liberam mediadores inflamatórios e contribuem para a aterogênese. O scFv (single ch

12. Thermal performance of a castor oil foam as insulating material inside the roof : study case in the city of Ilha Solteira, Brazil / Desempenho termico da espuma poliuretana a base de oleo de mamona utilizada em componentes da edificação (subcoberturas) : estudo em Ilha Solteira, SP
The aim of this work is to describe an experimental study using castor oil foam as an insulating material inside the roof. The castor oil foam inside the roof is an appropriate natural recycled material as a passive cooling strategy as opposite to the burning of fossil fuels for air conditioning (AC) and mechanical ventilation. The expected result of this re
