In this study, the essential oils extracted from the peels of Citrus aurantifolia, Citrus limon and Citrus sinensis were chemically characterized and quantified. These essential oils and their standards limonene, citral and limonene + citral were evaluated (at concentrations ranging from 500 to 3.91 mL·mL-1) regarding their anti-trypanosome, antifungal and antibacterial activities. The chemical identification and quantification (by GC/FID and GC/Ms) displayed the limonene as the major component of the three essential oils. It did not verified anti-trypanosome activity for all treatments. Regarding antimicrobial activity, the results were satisfactory against Gram-negative bacteria (staphylococcus aureus, Listeria. monocytogenes and salmonella cholerasuis) and funghi (Aspergillus niger, A. flavus and A. carbonarius), except for the bacterium Pseudomonas aeruginosa, which showed no inhibition for any treatment used.

Nowadays, the fast development of nanobiotechnology, has led to rapid diagnosis of important infectious diseases such as arboviruses-borne diseases, vector-borne infections and waterborne parasites diseases and others in order to reduce and avoid further dissemination of the infections within the general population. Furthermore, new nanomedicines based on the application of silver and gold nanoparticles which are less toxic, more effective, and that does not generate resistance could help to solve the problems of parasitic disease like leishmaniasis and chagas disease. It turns out that the combination of nanoparticles with antibiotics not only reduces the toxicity of both agents towards human cells but also enhances their ability to destroy bacteria by facilitating the binding of antibiotics to the microbes. Moreover, combining nanoparticles with antimicrobial peptides and essential oils with nanoparticles generates genuine synergy against microbial resistance.

This study evaluated in vitro activity of ethanol extract, fractions, and isolated substance from Amazon species against promastigotes of L. amazonensis. The ethanol extracts were concentrated and fractionation. The anti-promastigote activity was evaluated through the cell viability assessment method （MTT）. The ethanol extract, fractions, and isolated substance from Himatanthus articulatus and Parahancorniafasciculata were inactive in promastigote ofL. amazonensis, as the ethanol extract ofPhysalis angulata. The hexane fractions from different parts ofMontrichardia linifera showed anti-promastigote activity probably due to the presence of steroids and terpenes. All species in studies were inactive, except ofM. linifera. The few polar constituents can be responsible for the activity. Therefore, the isolation and purification of the active on L. amazonensis promastigotes are urgently required.

The consumption of freshwater fish and fish products has gradually grown worldwide over the last decades, generating a proportional waste increase. The objective of the present study was to assess the chemical and bacteriological quality of restructured fish product, meatball-type, prepared with rainbow trout (Onchorynchus mykiss) waste added of 1% transglutaminase (MTG), 4% textured soy protein (TsP) and replacing part of the sodium chloride with potassium chloride (75%/25%) as described below: T1—starch addition (control);T2—MTG addition (1%);T3—soy protein addition (4%);T4—soy protein addition (4%) and MTG addition (1%);T5—soy protein addition (4%), MTG addition (1%) and partial replacement of salt (75% NaCl/25% KCl). Total aerobic mesophilic bacteria (TAMB), 2-thiobarbituric acid reactive substances (TBARs), pH determination and quantification of biogenic amines were performed on the day after manufacturing (P0) and after 60 days of storage (P1) at -25℃?± 2℃. The results showed that there was no significant difference (p s and pH after storage. T4 presented the lowest total biogenic amine content (256.84 mg/kg) whereas T3 and T5 had the highest value (791.36 and 707.19 mg/kg, respectively) in this parameter. Putrescine was the biogenic amine that presented the highest concentration (504.00 mg/kg) in T3 and cadaverine that presented the smallest concentration (0.36 mg/kg) in T4. The use of technological strategies for developing new products with non-commercial fillets kept the most standards, having changes only in some biogenic amines.

Recruitment maneuvers in acute respiratory distress syndrome: The safe way is the best way

引用

World Journal of Critical Care Medicine 2015年第4期4卷 278-286页

作者： Raquel s santos Pedro L silva Paolo Pelosi Patricia RM Rocco Laboratory of Pulmonary Investigation Institute of Biophysics Carlos Chagas Filho Federal University of Rio de Janeiro IRCCs AOU san Martino-IsT Department of Surgical Sciences and Integrated Diagnostics University of Genoa

Acute respiratory distress syndrome(ARDs) represents a serious problem in critically ill patients and is associated with in-hospital mortality rates of 33%-52%. Recruitment maneuvers(RMs) are a simple, low-cost, feasible intervention that can be performed at the bedside in patients with ARDs. RMs are characterized by the application of airway pressure to increase transpulmonary pressure transiently. Once non-aerated lung units are reopened, improvements are observed in respiratory system mechanics, alveolar reaeration on computed tomography, and improvements in gas exchange(functional recruitment). However, the reopening process could lead to vascular compression, which can be associated with overinflation, and gas exchange may not improve as expected(anatomical recruitment). The purpose of this review was to discuss the effects of different RM strategies- sustained inflation, intermittent sighs, and stepwise increases of positive end-expiratory pressure(PEEP) and/or airway inspiratory pressure- on the following parameters: hemodynamics, oxygenation, barotrauma episodes, and lung recruitability through physiological variables and imaging techniques. RMs and PEEP titration are interdependent events for the success of ventilatory management. PEEP should be adjusted on the basis of respiratory system mechanics and oxygenation. Recent systematic reviews and meta-analyses suggest that RMs are associated with lower mortality in patients with ARDs. However, the optimal RM method(i.e., that providing the best balance of benefit and harm) and the effects of RMs on clinical outcome are still under discussion, and further evidence is needed.
