Barium titanate nanocrystallites were synthesized by a hydrothermal technique from barium chloride and tetrabutyl titanate. Single-crystalline cubic perovskite Ba TiO_3 consisting of spherical particles with diameters ranging from 10 to 30 nm was easily achieved by this route. In order to study the influence of the synthesis process on the morphology and the optical properties, barium titanate was also prepared by a solid-state reaction. In this case, only the tetragonal phase which crystallizes above 900 was observed. High-temperature X-ray diffraction measurements were performed to investigate the crystallization temperatures as well as the particle sizes via the Scherrer formula. The lattice vibrations were evidenced by infrared spectroscopy. Eu^(3+)was used as a structural probe, and the luminescence properties recorded from Ba TiO_3 :Eu^(3+)and elaborated by a solid-state reaction and hydrothermal process were compared. The reddish emission of the europium is increased by the nanometric particles.

Erbium and ytterbium doped barium titanate nanopowders were prepared using the hydrothermal method. A barium titanate structure doped with rare earth ions manifested new characteristics and improved the field of application of optical devices such as trichromatic tubes, LCD displays, lamps, and infrared lasers. In this work, BaTiO3：Er3＋ and BaTiO3：Yb3＋ were prepared using barium chloride [BaCl2], titanium butoxide [C16H36O4Ti], erbium chloride [ErCl3] and ytterbium chloride [YbCl3] as precursors. Anhydrous methanol was employed as a solvent. Metallic potassium was used to promote solubility in the system and increase the pH to 13. This method yielded the formation of a predominantly cubic structure in both Er3＋ and Yb3＋ doped BaTiO3 powders. Characteristic bondings of BaTiO3 were observed with FT-IR spectroscopy. The predominantly cubic structure was confirmed by X-ray diffraction and micro-Raman analyses. The particle size（～30 nm） was estimated using the Scherrer equation and X-ray diffraction data. The results were presented and discussed.

OBJECTIVES Elderly patients show a higher incidence of ischemic and bleeding events after percutaneous transluminal coron-ary intervention(PCI).We sought to investigate outcomes in elderly patients treated with antithrombotic strategy guided by bleeding and ischemic risks after revascularization with last generation everolimus-eluting stent(EES).METHODS Prospective multicenter registry including patients over 75 years revascularized with EES and antithrombotic ther-apy guided by clinical presentation,PCI complexity and PRECISE DAPT score.Co-primary safety endpoints were:(1)composite of cardiac death,myocardial infarction and stent thrombosis and;(2)bleeding(BARC 2-5).Primary efficacy endpoint was target lesion revascularization.A matched group of patients revascularized with current drug-eluting stents and no such tailored antith-rombotic therapy was used as control.RESULTS Finally,1064 patients were included in SIERRA-75 cohort,80.8±4.2 years,36.6%women,71%acute coronary syn-dromes(ACS)and 53.6%complex PCI.Co-primary safety endpoint of major adverse cardiovascular events was met in 6.2%,co-primary safety endpoint of bleeding in 7.8%and primary efficacy endpoint of TKLR in 1.5%.The multivariable adjusted model showed no significant association of the prescribed short/long dual antiplatelet therapy(DAPT)durations with any endpoint suggesting a well tailored therapy.No stent thrombosis reported in the subgroup with 1-3 months DAPT duration.As compared to control group,bleeding BARC 2-5 was significantly lower in SIERRA-75 group(7.4%vs.10.2%,P=0.04)as well as the net safety-efficacy endpoint(14.3%vs.18.5%,P=0.02).CONCLUSIONS In elderly population,the application of this risks-adjusted antithrombotic protocol after revascularization with last generation EES seems to be associated with an improved prognosis in terms of ischemic and bleeding outcomes.

Background:Chagas disease is an important health problem in Latin America due to its incapacitating effects and associated mortality.Studies on seropositivity for Trypanosoma cruzi in Mexican dogs have demonstrated a direct correlation between seropositivity in humans and dogs,which can act as sentinels for the disease in this region.The objective of this study was to determine the seropositivity for T.cruzi infection in dogs from Sonora,a northern borderstate of Mexico.Methods:Responsible pet owners were selected at random from an urban area of Empalme municipality,Sonora,Mexico,and from there,180 dog samples were collected.Anti-T.cruzi antibodies were determined using the enzymelinked immunosorbent assay(ELISA)method.Reactive ELISA sera were processed by indirect immunofluorescence to confirm the presence of anti-T.cruzi antibodies.For the statistical analysis,chi-square tests were conducted.Results:Dogs’sera showed a seropositivity rate of 4.44%.The rate of seropositivity was not associated with the dogs’age,sex,or socioeconomics pertaining to the geographical area.One sample(1/180,0.55%)showed the acute state of the disease.Conclusions:The study found a presence of anti-T.cruzi antibodies in dogs in this area,which suggests vector transmission.There is a need for active surveillance programs throughout the state of Sonora and vector control strategies should also be implemented in endemic regions.

Transcriptional regulation,determined by the chromatin structure and regulatory elements interacting at pro-moter regions,is a key step in plant responses to environmental cues.Nitrate(NO3-)is a nutrient signal that regulates the expression of hundreds of genes in Arabidopsis thaliana.Here,we integrate mRNA sequencing,genome-wide RNA polymeraseⅡ(RNPⅡ),chromatin immunoprecipitation sequencing,and DNase Sequencing datasets to establish the relationship between RNPⅡoccupancy and chromatin accessibility in response to NO3-treatments in Arabidopsis roots.Genomic footprinting allowed us to identify in vivo regula-tory elements controlling gene expression in response to NO3-treatments.NO3--modulated transcription factor(TF)footprints are important for a rapid increase in RNPⅡoccupancy and transcript accumulation over time.We mapped key TF regulatory interactions and functionally validated the role of NAP,an NAC-domain containing TF,as a new regulatory factor in NO3-transport.Taken together,our study provides a comprehensive view of transcriptional networks in response to a nutrient signal in Arabidopsis roots.

Efforts to improve crop yields with efficient use of fertilizers are needed to guarantee global food security.Enhanced slow-release fertilizer systems(SRFs)encapsulated in biodegradable matrices are being developed to address this global concern.From a wide range of strategies for SRFs development,we explored a natureinspired solution based on the plant cuticle model and its function as a membrane for water and nutrient transport control.Here,Candelilla wax,extracted from Candelilla wild plants(Euphorbia antisyphilitica),is studied as a renewable slow-release matrix for fertilizers encapsulated by a modified spray chilling process.From this process,microencapsulates containing 40 wt%of phosphorus fertilizer are obtained with distinctive sizes and chemical characteristics,presenting a slow-release behavior.Considering the abovementioned features,novel insights into fertilizer release mechanisms based on plant cuticle models are discussed.

The aim of the present study was to evaluate the effect of feeding four levels of tuna oil on performance and fatty acid (FA) profiles of broiler chicken meat. 240 Ross broiler chickens were randomly assigned to 20 pens and divided into four treatments: 0%, 0.75%, 1%, and 1.25% of tuna oil. At 49 days, breast and legs-thighs muscles were processed for FA analysis. Concentrations of FA in legs and thighs meat were significantly higher when compared with breast meat. In both types of meats (breast and legs-thighs), the inclusion of 1.0% or 1.25% of tuna oil in the diet significantly increased (P deposition of SFA, MFA, and PUFA in breast meat, while in legs and thighs these reductions were less noticeable. The significant reduction in the concentration of n-6 PUFA and the increment of n-3 PUFA were more evident in breast than in legs and thighs, and with the addition of 1% and 1.25% of tuna oil. The results of the present study suggest a difference in FA deposition attributable to supplementation with tuna oil. The addition of tuna oil could be recommendable to increase n-3 PUFA in both broiler chicken breast and legs-thighs meats, providing a healthier and functional chicken meat to consumer.

The study evaluated the effect of time and fatty acid (FA) composition in eggs of laying hens supplemented with tuna oil (TO). Two hundred White Leghorn hens 30-week were divided into 5 treatments with 4 replicates of 10 birds each. Treatments were assigned randomly and consisted of 0%, 0.75%, 1.50%, 2.25% and 3% TO in commercial sorghum-soybean meal diets, in which the soybean oil was partially replaced. The experiment was conducted for 90 days. At days 28, 56 and 84 of the experiment, 10 eggs per replicate were collected for chemical analysis. Feed intake, egg production rate, egg weight, and feed conversion were not influenced by dietary treatment. FA content was significantly altered (P ded. Levels of EPA and DHA were higher (P decrease in n-6 FA. There was a high correlation (P < 0.05) between TO inclusion level and the incorporation of linoleic acid (LA, r = -0.95) or arachidonic acid (AA, r = -0.96) into the egg yolk. The highest incorporation (P < 0.05) of total n-3 FA content in eggs was obtained with 3% TO/kg. This increase was proportional to TO inclusion levels in the diets (r = 0.95). The results indicate that the n-3 FA content in eggs can be increased by dietary supplementation with TO, and that TO can serve as a reasonable alternative feed ingredient in layer diets to produce a healthier choice of egg.
