To evaluate the therapeutic effects of bone marrow-derived CD11b+CD14+ monocytes in a murine model of chronic liver *** liver damage was induced in C57BL/6 mice by administration of carbon tetrachloride and ethanol for 6 mo. Bone marrow-derived monocytes isolated by immunomagnetic separation were used for therapy. The cell transplantation effects were evaluated by morphometry, biochemical assessment, immunohistochemistry and enzyme-linked immunosorbent ***11b+CD14+ monocyte therapy significantly reduced liver fibrosis and increased hepatic glutathione levels. Levels of pro-inflammatory cytokines, including tumor necrosis factor-α, interleukin (IL)-6 and IL-1β, in addition to pro-fibrotic factors, such as IL-13, transforming growth factor-β1 and tissue inhibitor of metalloproteinase-1 also decreased, while IL-10 and matrix metalloproteinase-9 increased in the monocyte-treated group. CD11b+CD14+ monocyte transplantation caused significant changes in the hepatic expression of α-smooth muscle actin and *** therapy is capable of bringing about improvement of liver fibrosis by reducing oxidative stress and inflammation, as well as increasing anti-fibrogenic factors.

Intra-abdominal infections can be classified into uncomplicated or complicated(peritonitis). Peritonitis is divided into primary, secondary, and tertiary. Tertiaryperitonitis is the less common but the most severe among peritonitisstratifications, being defined as a recurrent intra-abdominal infection that occurs48 h after a well-succeeded control of a secondary peritonitis. This disease has acomplex pathogenesis that is closely related to the capacity of the peritonealcavity to activate immunological processes. Patients who progress to persistentperitonitis are at an increased risk of developing several infectious complicationssuch as sepsis and multiple organ failure syndrome. Moreover, tertiary peritonitisremains an important cause of hospital death mainly among patients withassociated risk factors. The microbiological profile of organisms causing tertiaryperitonitis is often different from that observed in other types of peritonitis. Inaddition, there is a high prevalence of multidrug-resistant pathogens causing thiscondition, and an appropriate and successful clinical management depends on anearly diagnosis, which can be made easier with the use of clinical scorespresenting a good prediction value during the intensive care unit ***, immediate therapy should be performed to control theinfectious focus and to prevent new recurrences. In this sense, the treatment isbased on initial antimicrobial therapy and well-performed peritoneal drainage.

In multi-phase flows, the phases can flow and arranged in different spatial configurations in the pipe, which called flow patterns. This type of flow is found in the oil, chemical and nuclear industries. For example, in the production and transport of oil and gas, the identification of the flow patterns are essential for answering those questions which are related to the economic return of the field, such as, measuring the volumetric flow, determining the pressure drop along the flow lines, production management and supervision. In offshore production, these factors are very important. This paper presents a new method for measuring the void fraction in horizontal pipelines, taking the air as gas in water-air two-phase flow. Through acoustic analysis of the frequency response of the pipe, the method gets the parameters to changes in runoff regime, in an experimental arrangement constructed on a small scale. The main advantages are the non-intrusive characteristic and easy to implement. The paper is composed of a qualitative experimental evaluation and transducers （microphone） which are used to analyze variations in the response accompanying variations in void and flow pattern changes. Changes are imposed and controlled by a two-phase flow experimental simulation rig, including a measurement cell constituted of an external casing that can isolate the measurement from the environmental background noise fitted with acoustic pressure transducers radially arranged, and the impact of a monitored excitation mechanism. The signals which captured by the microphones are processed and analyzed by checking their frequency contents changes according to the amount of air in the mixture.

Focus on customer experience has proven to be one of the most important tools for the acceptance of the message of a brand by Millennials （Generation Y）. The aim of this study is to demonstrate how Generation Y influences, through their behavior and customs, the decisions to be made by the marketing area of companies. In this sense, the study seeks to demonstrate this situation by addressing the running market, which is consistently growing in Brazil and has unexplored niches, as in the case of a group of young runners who belong to Generation Y that called the attention of Nike＇s running segment, and was the focus of this research study. The case study was conducted by the qualitative method, based on an empirical investigation, in addition to a literature review. In this sense, it addressed the emergence of Generation Y, and how was the progress of the media that monitored it during this transition, going through multi-platform advertising. This approach is followed by a study of the running market and the role of Nike in it, how the project emerged and its relationship with Generation Y＇s behavior.

Biodegradable Zn-based alloys, particularly Zn-Mg alloys with the addition of alloying elements, have been intensively investigated aiming to improve both mechanical properties and corrosion behavior. Since such properties are strongly dependent on the alloy microstructure, any evaluation should commence on understanding the conditions influencing its formation. In this study, the effect of the solidification cooling rate on the microstructural evolution of Zn-1 wt.%Mg-(0.5 wt.%Ca, 0.5 wt.%Mn) alloys during transient solidification was investigated. The results show that the microstructures of both alloys have three phases in common: η-Zn dendritic matrix, intermetallic compounds(IMCs) Zn11Mg2, and Zn2 Mg in the eutectic mixture. MnZn9 and two Ca-bearing phases(CaZn11 and CaZn13) are associated with Mn and Ca additions, respectively. These additions are shown to refine the dendritic matrix and the eutectic mixture as compared to the Zn-1 wt.%Mg alloy. A correlation between cooling rate, dendritic or eutectic spacings was developed, thus permitting experimental growth laws to be proposed. Additionally, hardness tests were performed to evaluate the effects of additions of Ca and Mn. Experimental correlations between Vickers microhardness and secondary dendritic spacings were proposed, showing that the microstructural refinement and characteristic Ca and Mn based IMCs induce an increase in hardness as compared to the binary alloy.
