Chitin powder and chitin-aerogel were prepared from shrimp wastes and used to uptake Y^(3+)from aqueous solutions and concentrate this rare earth element from phosphogypsum(PG).Chitin aerogel displays a specific surface area of 945 m^(2)/g,while chitin powder is 3.6 m^(2)/g,which largely influences its adsorption *** the adsorption in synthetic solutions,the effect of pH on Y^(3+)removal is strong for chitin powder *** contrast,no big pH influence was detected for chitin *** interactions and chelation can highlight the proposed mechanism of Y^(3+)on chitin adsorbents for the powder and ***,in addition to these interactions,pore filling/pore diffusion is the main mechanism of Y^(3+)removal in the chitin *** aerogel is efficient in concentrating 8 times the Y^(3+)from PG,a very complex *** complex chitin aerogel-Y^(3+)can be a secondary source of rare earth elements for other applications.

AIM To evaluate the sex-specific effects of a hydroalcoholic extract from eugenia punicifolia(HeeP) leaves on gastric ulcer *** In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HeeP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HeeP was evaluated in terms of subacute toxicity and *** Compared to the vehicle, HeeP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HeeP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HeeP was mediated by prostaglandin e2 only in male rats. Overall, the beneficial effect of HeeP was the highest in intact females. Notably, HeeP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HeeP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HeeP was *** In gastric ulcers, HeeP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration.

Unconventional vegetables, in general, are plants that have been largely consumed by the population at some point and, because of changes in eating behavior, now present reduced economic and social expression and have lost ground to other vegetables. The objectives of this study were to perform phytochemical screening of the ethanol extracts of Rumex acetosa L., Tropaeolum majus L., solanum muricatum, stachys byzantina K. Koch and solanum betaceum Cav. and evaluate their antioxidant potentials via the methods involving scavaging of the DPPH free radical and the ABTs radical, phosphomolybdenum and reducing power. In phytochemical screening, five species of unconventional vegetables tested positive for tannins;for sesquiterpene, lactones and other lactones. These tests were positive for Tropaeolum majus L. and Rumex acetosa L., solanum betaceum Cav. and solanum muricatum tested negative for steroids. Only solanum betaceum Cav. gave positive tests for flavonoids. Among the five plant species studied, stachys byzantina K. Koch presented the greatest antioxidant potential in all the methods evaluated.

Acoustic emission monitoring is often used in the diagnosis of electrical and mechanical incipient faults in the high voltage apparatus. Partial discharges are a major source of insulation failure in electric power transformers, and the differentiation from other sources of acoustic emission is of the utmost importance. This paper reports the development of a new sensor concept - a fiber laser sensor based on a phase-shifted chirped fiber grating - for the acoustic emission detection of incipient faults in oil-filled power transformers. These sensors can be placed in the inner surface of the transformer tank wall, not affecting the insulation integrity of the structure and improving fault detection and location. The performance of the sensing head is characterized and compared for different surrounding media： air, water, and oil. The results obtained indicate the feasibility of this sensing approach for the industrial development of practical solutions.

Protozoan diseases such as Visceral Leishmaniasis (VL) have re-emerged in Northern Brazil and cases of Chagas Disease also occur. This VL increase leads to early therapy for the public. Confirmatory parasitological diagnoses in VL are performed by bone marrow or spleen aspiration, but eLIsA, IFA or immunochromatographic tests for antibody detection are easily performed and can be used in the presence of clinical signs as confirmatory for specific therapy. This approach is successful in providing therapy and prevention of death in VL, but there is a chance of confusion with the emerging disease, Chagas Disease (CD), due to cross-reacting and similar clinical pictures, as in this case. Both VL and CD presented many asymptomatic or oligosymptomatic cases, complicating the picture. Our case report emphasizes these aspects. Positive serology, with an IIF titer of 1/160, and epidemiological correlation, suggests the diagnosis of VL and imposes antimony therapy. Despite the unfavorable evolution and signs of cardiac involvement, the presence of pericarditis and cardiac tamponade confirmed by the echocardiogram suggests CD. We reassessed the profiles of a suggested CD serology, the diagnosis was corrected and treatment with CD specific benznidazole. The good evolution started with benznidazole corroborates the diagnosis of CD and discards the hypothesis of double infection.

This work examines the environmental and geochemical impact of recycled aggregate concrete production with properties representative for structural applications. The environmental influence of cement content, aggregate production, transportation, and waste landfilling is analysed by undertaking a life cycle assessment and considering a life cycle inventory largely specific for the region. To obtain a detailed insight into the optimum life cycle parameters, a sensitivity study is carried out in which supplementary cementitious materials, different values of natural-to-recycled aggregate content ratio and case-specific transportation distances were considered. The results show that carbon emissions were between 323 and 332 kg CO2e per cubic metre of cement only natural aggregate concrete. These values can be reduced by up to 17% by replacing 25% of the cement with fly ash. By contrast, carbon emissions can increase when natural coarse aggregates are replaced by recycled aggregates in proportions of 50% and 100%, and transportation is not included in analysis. However, the concrete with 50% recycled aggregate presented lower increase, only 0.3% and 3.4% for normal and high strength concrete, respectively. In some cases, the relative contribution of transportation to the total carbon emissions increased when cement was replaced by fly ash in proportions of 25%, and case-specific transportation distances were considered. In absolute values, the concrete mixes with 100% recycled aggregates and 25% fly ash had lower carbon emissions than concrete with cement and natural aggregates only. Higher environmental benefits can be obtained when the transportation distances of fly ash are relatively short(15–25 km) and the cement replacement by fly ash is equal or higher than 25%, considering that the mechanical properties are adequate for practical application. The observations from this paper show that recycled aggregate concrete with strength characteristics representative for s

The CBM （chromoblastomycosis） is a disease caused by dematiaceous fungi, which has the species Fonsecaea pedrosoi as main agent. This fungus is found in warm and moist climates, characteristically found in the amazonic lands of the region, where its environmental isolation was once described. This research aimed to identify the healthy population exposed to agent F. pedrosoi in four villages located in the Legal Amazon. In order to clarify the risk factors for allergic immune exposure, a survey was conducted by the technique of delayed skin reaction （IDR） with the metabolic antigen （chromomycin） in 449 healthy individuals. The results showed that 14.9% （67 subjects） were IDR positive, with induration 〉 5 mm.
