The use of entomopathogenic fungi (EF) in recent years has been highly effective against the different orders of insects considered pests of agricultural importance and their conidia have been commonly applied, but it has been reported that these are sensitive to the environmental conditions. For this reason, biopesticides products have been formulated based on secondary metabolites, recently. These biomolecules participate as biological control agent, such as: cyclic depsipeptides, amino acids, polyketides, polyphenols and terpenoids, affecting their morphology, life cycle and insect behavior. The use of secondary metabolites of entomopathogenic fungi opens the possibility of application in a more efficient way for the control of agricultural pests in a compatible with the environment and human health;therefore, it is important to know, analyzing the type of molecules, their effects, and their different methods of application.

Understanding the biological parameters of some triatomine subspecies of Meccus phyllosomus （Burmeister） is a crucial first step in estimating the epidemiologie importance of this group. Biological parameters related to hatching, lifetime, number of blood meals to molt, percentage of females at the end of the cycle, number of laid eggs, and mortality for each instar of 3 M. phyllosomus subspecies [M. p. mazzottii （Usinger）, M. p. pallidipennis （Stal）, and M. p. phyllosomus] and their laboratory hybrids were evaluated and compared. No significant differences （P 〉 0.05） were found among the experimental hybrids （MaPa, MaPhy, PaPhy） and reciprocal cohorts. In 5 （hatching, number of blood meals to molt, accumulative mortality, percentage of females, and mean number of laid eggs） of the 6 studied parameters （with the exception of development time）, the hybrid cohorts had better fitness results than the parental cohorts involved in each set of crosses. The increase in hybrid fitness found in our study could lead to an increase in the epidemiologic risks caused by transmission of Trypanosoma cruzi to humans.

In this research, an attempt was made to improve compatibility in a polymer blend composed of incompatible constituents, namely, recycled polystyrene (rPS) and polystyrene-co-acrylonitrile (SAN), through the addition of a compatibilizer. The compatibilizing agent, styrene-ethylenebutadiene-styrene block copolymer (SEBS), was added to the polymer blend in ratios of 5 and 10 wt%. For this purpose, blends of rPS and SAN at different ratios, without and with varying concentrations of compatibilizer, were prepared by melt blending using a co-rotating twin-screwextruder. Mechanical properties including tensile and impact strength, rheological properties (RPA), thermal behaviour (DSC) and morphological characteristics (SEM) were evaluated. According to the results obtained by complex viscosity, the blends behave as a pseudoplastic fluid. The results showed that the addition of SEBS increased the Izod impact strength and the elongation at break and decreased the tensile strength and tensile modulus. rPS/SAN blend modified with SEBS had better mechanical properties than the rPS/SAN alloy. SEM photographs revealed that the SEBS was not only distributed in the SAN phase but also distributed in rPS phase in rPS/SAN/SEBS blend. Furthermore, DSC analysis for blends of rPS/SAN gave a good indication of the improvement on miscibility for most compositions. SEM micrographs of tensile fracture surfaces indicated that the formation of the co-continuous phase and the improvement of interface adhesion are the most important reasons for the excellent tensile properties of the rPS/SAN/SEBS blends. Within the range of analysed compositions, the morphologies investigated by SEM are typical of immiscible blends.

This study explored the cortical functionality in young women while reading a sexually-explicit text. Electroencephalographic activity (EEG) was recorded in heterosexual women while reading either a sexually-explicit text or one with neutral content. Absolute power (AP) and the degree of EEG synchronization among the prefrontal, temporal and parietal cortices were analyzed for the different EEG bands. To evaluate sexual arousal, valence and general activation, Likert-type and Manikin scales were applied. Subjects scored the sexually-explicit text as more pleasurable, and reported greater general activation and sexual arousal than while reading the neutral one. During reading of the sexually-explicit text only, they showed a higher AP in the beta and gamma bands in temporal areas in both hemispheres, and in the theta band in parietal ones, with a lower degree of EEG synchronization between prefronto-temporal areas in the fast bands. Results show that both hemispheres were activated in these sexually-aroused women. The low bilateral synchronization between prefrontal and temporal regions indicates the independent functionality of these cortices, which could be a requirement for inducing and maintaining sexual arousal during reading of sexually-explicit texts in women. These data should broaden our knowledge of the cortical mechanisms that underlie sexual arousal in women.

Background The association between parental perception of child's weight and their attitudes towards his/her dietary habits has not been reported yet.This study aimed to assess the association between parental underestimation of child's weight and parental attitudes towards child's dietary habits.Methods We conducted a cross-sectional analysis of SENDO cohort participants recruited between January 2015 and June 2020.All information was collected through online questionnaires completed by parents.We calculated crude and multivariable-adjusted odds ratio(OR)and 95%confidence intervals(CI)for unhealthy attitudes towards child's dietary habits associated with parental underestimation of child's weight.Results Sixteen percent of children in the SENDO project had parents who underestimated their weight.Parents who under-estimated their child's weight status were more likely to have unhealthy attitudes toward his/her dietary habits[OR 3.35;95%CI(1.71-6.53)].Conclusions Parental underestimation of child's weight was associated with unhealthy attitudes towards child's dietary hab-its.Pediatricians and public health practitioners should pay attention to the parental perception of child's weight to identify parents who underestimate it as an at-risk group in which to inquire about lifestyle and dietary habits.

There has been an increase of community studies that incorporate the use of functional diversity indices. The incorporation of these indices in the analysis of marine communities is recent, however, could contribute with relevant information about the health of those communities. The lagoon of La Paz is a body of water located in La Paz, B.C.S., México. Despite its regional importance, there are not recent studies about its fish communities. Therefore, the aim of the present study was to analyze the temporal and spatial structure of the functional diversity of fish communities associated to soft bottoms, from August 2016 to July 2017, as well as important environmental variables. Functional diversity indices showed significant differences between months. Spatial analysis did not show significant differences perhaps due to low variability of the type of substrate. Temperature showed temporal differences as well. Therefore, temperature may be a limiting environmental variable for many fish species inhabiting coastal lagoons.

This study presents the implementation of a desulphurization process for lead recycling under different chemical and physical conditions using pyro-metallurgical processes. Desulphurization was done using a hydrometallurgical process using sodium carbonate as a desulphurization agent and different lead-bearing loads compositions. Waste characterization included: SO2 concentrations in the stack emissions, total lead content in the furnace ash, the total lead content in the slag, and the toxicity characteristic leaching procedure (TCLP). A significant reduction in SO2 emissions was achieved (~55% reduction) where mean SO2 concentrations changed from 2193 ± 135 ppm to 1006 ± 62 ppm after the implementation of the modified processes. The desulfurized lead paste (i.e. the metallic fraction lead of the battery) of the modified process exhibited an improvement in the concentration of the lead in the TCLP test, with an average value of 1.5 ppm which is below US EPA limit of 5 ppm. The traditional process TCLP mean value for the TCLP was 54.2 ppm. The total lead content in the bag house ashes shows not significant variations, when comparing the desulphurization (67.6% m/m) and non-desulphurization process (64.9% m/m). The total lead mean content in the slag was higher in the desulphurization process (2.49% m/m) than the traditional process (1.91% m/m). Overall, the implementation of a new desulphurization method would potentially increase the operation costs in 10.3%. At the light of these results, a combination of hydrometallurgical and pyro-metallurgical processes in the recycling of lead-acid batteries can be used to reduce the environmental impact of these industries but would increase the operational costs of small lead recyclers.

CdS, CdSe and PbS films were grown onto glass by chemical bath deposition (CBD). Different constant deposition temperatures (Td) were employed in the range 0-80 °C with subintervals of 10 °C. Concentration of reagents, pH, and stirring were maintained constants. A microcrystalline mixture CdCO3 and CdS were grown. At intermediates Td values a mixture of both materials present. i. e., For Td? 40 °C, the intensity of the main of X-ray Diffraction (XRD) CdS peak is abruptly reduced. By scanning electronic microscopy (SEM) with Td = 80 °C, concentration atomic: Cd = 49.10, S = 51.90, for Td? 70 °C, increase of carbon and oxygen. The CdSe, average grain size (GS) increased monotonic with Td, reaching saturation of 70 °C, with GS values of 5-16 nm. At low Td values (0-20 °C), the structural phase was found, and the high Td = 70 °C on material 5-16 nm was appreciated transition to phase: Wurzite (W)? Zinbclende (ZB) and phases mixture: W/ZB, grain size (GS) 9-27 nm. By (XRD), PbS grow in W phase at all films, for Td = 60 °C, was observed preferential orientation in plane [111] with (GS) of 19-26 nm also a Gibbs free energy calculation is included.

The concentration of atoms was obtained by Scanning Electron Microscopy (SEM), S = 14.11-42.57, Cd = 49.11-59.59, and Se = 50.99-2.29, X-ray diffraction, identifies mixture of Wurzite/Zinc blende doped films phases and size of grain of 24-15 nm. Optical Absorption Spectra have redshifts of the forbidden band gap (Eg) of 1.8-2.3 eV. Raman spectra (RS) show the Raman shift, confirming formation of nanocrystals. From the dark conductivity vs. 1/kT behavior on the 100-500 K range, attributed to doping effects at the grain boundaries and quantum confinements. A thermodynamic model is proposed using the equation of Nernst to evaluate changes in the Gibbs free energy and investigate the spontaneity of reactions.

AIM:To evaluates the effectiveness and safety of the first generation,NS3/4A protease inhibitors(PIs) in clinical practice against chronic C virus,especially in patients with advanced fibrosis. METHODS:Prospective study and non-experimental analysis of a multicentre cohort of 38 Spanish hospitals that includes patients with chronic hepatitis C genotype 1,treatment-na?ve(TN) or treatment-experienced(TE),who underwent triple therapy with the first generation NS3/4A protease inhibitors,boceprevir(BOC) and telaprevir(TVR),in combination with pegylated interferon and ribavirin. The patients were treatment in routine practice settings. Data on the study population and on adverse clinical and virologic effects were compiled during the treatment period and during follow up.RESULTS:One thousand and fifty seven patients were included,405(38%) were treated with BOC and 652(62%) with TVR. Of this total,30%(n = 319) were TN and the remaining were TE:28%(n = 298) relapsers,12%(n = 123) partial responders(PR),25%(n = 260) null-responders(NR) and for 5%(n = 57) with prior response unknown. The rate of sustained virologic response(SVR) by intention-to-treatment(ITT) was greater in those treated with TVR(65%) than in those treated with BOC(52%)(P < 0.0001),whereas by modified intention-to-treatment(m ITT) no were found significant differences. By degree of fibrosis,56% of patients were F4 and the highest SVR rates were recorded in the non-F4 patients,both TN and TE. In the analysis by groups,the TN patients treated with TVR by ITT showed a higher SVR(P = 0.005). However,by m ITT there were no significant differences between BOC and TVR. In the multivariate analysis by m ITT,the significant SVR factors were relapsers,IL28 B CC and non-F4; the type of treatment(BOC or TVR) was not significant. The lowest SVR values were presented by the F4-NR patients,treated with BOC(46%) or with TVR(45%). 28% of the patients interrupted the treatment,mainly by non-viral response(51%):this outcome was more frequent in the TE than in the TN patients
