This study evaluated the effects of increasing levels of the greasy babassu byproduct (GBB) in the diet of lambs on the fatty acid (FA) profile of abomasal digesta content, meat quality traits, and ...meat FA profile. Twenty-eight crossbred Dorper × Santa Inês growing lambs (20.6 ± 4.1 kg of initial body weight and 145 ± 12 days old) were fed one of four experimental diets as dry matter (DM): 1) basal diet (i.e. without the GBB, CON), 2) basal diet with 50 g/kg GBB (50GBB), 3) basal diet with 100 g/kg GBB (100GBB) and, 4) basal diet with 150 g/kg GBB (150 GBB). The animals (experimental unit) were distributed in a randomized design, 4 treatments and 7 replications of each treatment. The GBB addition increased the DM intake linearly but decreased nutrient utilization, resulting in no changes in metabolizable energy intake and consequently, growth performance. Meat chemical composition, physical traits, and sensory evaluation were not affected by diet. The GBB diet increased the abomasal contents of 10:0, 12:0 and 14:0 and tended to decrease 18:0, appointing for the negative interference on the rumen biohydrogenation (BH) of 18:2 n–6 and 18:3 n–3. The changes in the abomasal FA content did not affect the meat FA profile, except for a slight increment of 12:0, with increasing dietary GBB. Thus GBB, up to 150 g/kg of dietary DM, can be used as an alternative energy source for lambs, promoting slight changes in FA abomasal contents and rumen BH, without modifying growth performance, meat quality, and meat FA composition.
•Greasy babassu byproduct (GBB) increased saturated fatty acid (FA) intake.•GBB addition did not affect the physicochemical and sensory attributes of meat.•The abomasal FA content and rumen biohydrogenation slightly changed with GBB addition.
The aim of this work was to explore the potential risk of vector-borne Chagas disease in urban districts in northeastern Brazil, by analyzing the spatiotemporal distributions and natural infection ...rates with Trypanosoma cruzi of triatomine species captured in recent years. The main motivation of this work was an acute human case of Chagas disease reported in 2008 in the municipality of Sobral.
We analyzed data from community-based entomological surveillance carried out from 2010 to 2014. Triatomine natural T. cruzi infection was assessed by examination of insect feces by optical microscopy. Sites of triatomine capture were georeferenced through Google Earth and analyzed with ArcGIS. A total of 191 triatomines were collected, consisting of 82.2% Triatoma pseudomaculata, 7.9% Rhodnius nasutus, 5.8% T. brasiliensis, 3.7% Panstrongylus lutzi, and 0.5% P. megistus, with an overall natural infection index of 17.8%. Most infestations were reported in the districts of Dom José (36.2%), Padre Palhano (24.7%), and Alto do Cristo (10.6%). The overwhelming majority of insects (185/96.9%) were captured inside houses, and most insects tended to be collected in intermittent peaks. Moreover, captured triatomines tended to constitute colonies. The acute case reported in 2008 was found to be situated within a T. pseudomaculata hotspot.
The triatomine collection events carried out by dwellers were aggregated in time and space into distinct foci, suggesting that insects are intermittently and artificially introduced into the city, possibly via accidental migration from their natural reservoirs. The relatively high T. cruzi infection rate indicates considerable circulation of the parasite in these areas, increasing the risk of vector-borne Chagas disease infection. These data suggest a need to strengthen epidemiological surveillance and integrate appropriate control actions targeting triatomines, T. cruzi reservoirs, and human populations. Our data also identify Chagas disease transmission as a hazard in urban areas of Sobral.

Forty crossbred (Santa Ines × Dorper) male lambs were used to investigate the effect of dietary buriti oil (BOIL) intake on meat quality, fatty acid (FA) composition and sensory attributes. A ...completely randomized design with five BOIL intake levels (0, 12, 24, 36 and 48 g/kg DM) was used. Increasing dietary BOIL intake linearly reduced the DMI, slaughter weight, cooking loss, shear force, yellowness, 16:0, c9–18:1 FA concentrations, and the delta-9-desaturase activity index computed using c9–16:1 and 16:0 as product and substrate pair, cis-MUFA and ƩMUFA/ƩSFA ratio of lamb meat (P ≤ 0.05); however, increasing dietary BOIL intake quadratically increased the energy intake, lipid content and linearly increased the total FA intake, chroma, collagen, total BI, 18:0, 20:3n–6 concentration and sensory attributes of lamb meat (P ≤ 0.05), without affecting health indexes regarding fat consumption. BOIL addition at levels above 24 g/kg DM in lamb diet reduces growth, however, improves tenderness, flavor and “goat” aroma intensity and slightly changes meat FA levels, promoting better acceptance by panelists.
•Feeding Buriti oil to lambs increased the 18:0 and decreased the 16:0 of meat.•Feeding Buriti oil to lambs decreased the yellowness, shear force and goaty aroma of meat.•Feeding Buriti oil to lambs decreased the “goaty” flavor.•Lambs fed with BOIL had better “goaty” flavor and aroma intensity in meat.
Increasing use of zebrafish in drug discovery and mechanistic toxicology demands knowledge of cytochrome P450 (CYP) gene regulation and function. CYP enzymes catalyze oxidative transformation leading ...to activation or inactivation of many endogenous and exogenous chemicals, with consequences for normal physiology and disease processes. Many CYPs potentially have roles in developmental specification, and many chemicals that cause developmental abnormalities are substrates for CYPs. Here we identify and annotate the full suite of CYP genes in zebrafish, compare these to the human CYP gene complement, and determine the expression of CYP genes during normal development.
Zebrafish have a total of 94 CYP genes, distributed among 18 gene families found also in mammals. There are 32 genes in CYP families 5 to 51, most of which are direct orthologs of human CYPs that are involved in endogenous functions including synthesis or inactivation of regulatory molecules. The high degree of sequence similarity suggests conservation of enzyme activities for these CYPs, confirmed in reports for some steroidogenic enzymes (e.g. CYP19, aromatase; CYP11A, P450scc; CYP17, steroid 17a-hydroxylase), and the CYP26 retinoic acid hydroxylases. Complexity is much greater in gene families 1, 2, and 3, which include CYPs prominent in metabolism of drugs and pollutants, as well as of endogenous substrates. There are orthologous relationships for some CYP1 s and some CYP3 s between zebrafish and human. In contrast, zebrafish have 47 CYP2 genes, compared to 16 in human, with only two (CYP2R1 and CYP2U1) recognized as orthologous based on sequence. Analysis of shared synteny identified CYP2 gene clusters evolutionarily related to mammalian CYP2 s, as well as unique clusters.
Transcript profiling by microarray and quantitative PCR revealed that the majority of zebrafish CYP genes are expressed in embryos, with waves of expression of different sets of genes over the course of development. Transcripts of some CYP occur also in oocytes. The results provide a foundation for the use of zebrafish as a model in toxicological, pharmacological and chemical disease research.

Abstract The present study focuses on the determination of human temporal tendons and deep temporal fascia biomechanical behavior. The tensile and shear loads generated by the temporal muscle are ...transmitted to the masticatory system by the temporal tendons and muscle fascia. Establishing these connective tissues' biomechanical properties will help to develop proper finite element-based simulations of the human masticatory system, which will allow better understanding of diseases affecting the temporomandibular joint. The tissues were harvested from 8 male fresh cadavers, who were subjected to uniaxial tension tests. Available literature states that different connective tissues undergo identical biochemical, cellular and mechanical changes during senescence. Several mechanical phenomena occur during maturation, resulting in stiffer, stronger and more stable connective tissues, although less flexible. Based on this evidence, the present study suggests that older temporal tendon and fascia samples are stiffer than younger ones. We also found significant higher secant moduli with increasing age.
Introduction
Antisocial disorder is characterised by difficulty to adapt to social norms that normally rule different aspects of the person’s conduct in adolescence and adulthood. According to DSM-V, ...this disorder’s prevalence stands between 0.2% and 3%, and is more frequent in men.
Objectives
Numerous studies have been made about the influence between the environment and genetics for the development of this disorder, finding in several patients a punctual mutation of the monoamine oxidase gen (MAOA); although impulsive behaviour has also been associated to the 5-HT tranporte gene (5-HTT), and the protein coding gene for Tryptophan Hydroxylase TPH1
Methods
The hospital admission for these patients must be made when there’s autoregressive or hetero aggressive behaviour, suicide attempts, psychotic symptoms, or symptoms that generate important repercussions in the person’s normal functions. Nevertheless, is important to identify during the hospitalization the improvement possibilities of these patients in order to make drug or psychotherapy adjustments; in the case that we don’t observe treatment benefits, the patient will be released from the hospitalization
Results
The main treatment is psychotherapy.
Conclusions
There’s not much evidence of drug use in this disorder, however, mood stabilizers, antidepressants, atypical antipshychotics and benzodiazepines are used for rage control, impulsiveness, anxiety and aggressiveness.
Disclosure
No significant relationships.
The main aim of the study was to propose a useful methodological approach to define easily understandable indicators to use in communication campaigns organized to improve the efficacy of municipal ...solid waste collection. For this purpose, six economic-environmental indicators were defined, combining life cycle thinking and environmental communication. The indicators make it possible to obtain several combinations that can follow a variety of communication channels. Three indicators (quantity of recyclable materials recoverable from unsorted residual waste; total potential economic saving; number of jobs for young people as communicators) are expressed in absolute value and therefore refer to the whole community even if they are also good for single-targeted messages. The other three indicators (potential economic saving for each citizen; per capita saving of carbon dioxide equivalent; per capita saving of Disability Adjusted Life Years) are normalized with respect to the number of inhabitants and therefore refer to the individual citizen, but can also be used for global messages. As a case example, the methodology was applied to the collection of paper and cardboard in twelve Southern Italy cities obtaining very promising results. For example, the maximum quantity of paper and cardboard recoverable from unsorted waste would allow Naples and Palermo to recover more than €15 million. The maximum potential economic saving for each citizen was 25 €/capita. The economic saving obtained for Naples and Palermo could be translated in more than one thousand positions as young environmental communicators. Catania was the city with both the highest per capita potential saving of carbon dioxide (>60 kg CO2eq./capita) and maximum hypothetical per capita ‘life-time recovery’ (almost an hour). The innovative communication method used (‘Greenopoli’) assumed that school is the starting point to obtain a change of mindset because speaking with students (all potential communicators) means indirectly communicating with all other targets.

Differential capacitive sensor typology: a) a differential pressure sensor, the pressure moves plate D changing its distance from the fixed plates A and B; b) a micro-balance, the weight moves plate ...D changing its overlapping area with respect to the fixed plates A and B.
Display omitted
This manuscript presents the development of an integrated analog interface able to convert differential capacitive sensors variations into a DC voltage. The presented circuit exploits the architecture developed in previous works of the same authors, based on autobalancing bridge techniques, further improving its performances through the linearization of the input/output characteristic and the achievement of the full-range sensor variations capability. The interface takes advantage of Low Voltage and Low Power integrated circuit design techniques, optimizing performances for flux and force sensor. Simulated results with the AMS 0.35um standard CMOS technology have shown a very good agreement with the theoretical model developed, obtaining an error lower than 2.5% and a total power consumption of 5 mW. Moreover, waiting for the chip production, a discrete element board has been also implemented and tested. Preliminary measurements on the test board have shown satisfactory input/output linearity characteristics with overall reduced percentage error (lower than 1.5%) in the measurand estimation.
In cull ewes, energy supply by time short periods can affect growth, carcass traits, and meat quality. The objective of this study was to evaluate the effect of biscuit bran (BB) and cashew nut bran ...(CNB) in diets with different total digestible nutrient (TDN) content on animal performance and carcass and meat traits of cull ewes. Twenty Morada Nova cull ewes, with the initial BW of 30.1 ± 3.56 kg, and three years of age were distributed in a completely randomized design into factorial scheme 2 × 2, with two energy sources (BB and CNB) × two levels of TDN. All diets were isoproteic with variations in TDN content increased by 10% (TDN10) and 25% (TDN25) above the recommended requirement for the study category, which was 66.0% TDN. The experimental period lasted 56 days, in which daily intake in relation to metabolic weight and weight performance of the animals was determined. The hot carcass, the cold carcass, commercial cuts, loin eye area, and subcutaneous fat thickness were measured, obtained, or calculated. A sample of the Longissimus lumborum (LL) muscle was used by determination of physical–chemical composition, sensory, and fatty acid (FA) profile analysis. The ANOVA was performed to access the effect of diet and energy level on the characteristics studied, and means were compared by the Turkey and Kruskal Wallis tests at 5% of probability. A higher daily gain weight was observed from TDN25 (P = 0.006). Among by-products, higher nutrient intakes were observed in animals fed with BB diets (P < 0.01), except for crude protein. The same patterns have been observed for live weight, reconstituted half-carcass, higher yield in fat thickness, and internal carcass length. Cashew nut bran produced darker colored meat (P = 0.017) and higher cooking weight loss (P = 0.008). Higher lipid content was observed in animals submitted to diets with CNB and TDN25 (P = 0.001). The internal length of the carcass was higher in animals fed with BB (P = 0.041). All diets did not effect on sensory characteristics (P > 0.05). Total digestible nutrient in 25% above recommended promotes higher weight gain and meat with higher lipid content and less weight loss by cooling. The inclusion of BB, compared to CNB, provides a higher weight of carcasses and better conformation, in addition to lower total lipid content with higher proportion for monounsaturated FAs in meat, providing more attractive features for the consumer market.
