title: Acid Hydrolysis of Regular Corn Starch under External Electric Field

description: The main objective of the present work is the investigation of a new method for starch hydrolysis. For this, we proposed the acid hydrolysis under the action of an external electric field, able to develop a faster reaction than the conventional one. Corn starch with 18% amylose was subjected to a fixed voltage, varying the external electric field application time and the number of cycles. Morphology, crystallinity, and thermal stability of the starches were investigated by optical and scanning electron microscopy (SEM), X-ray diffraction (XRD), and small-angle X-ray scattering (SAXS). The results showed that the acid hydrolysis coupled with an external electric field allows a significant reduction in hydrolysis time, due to the orientation of the electrolyte ions. Cavities were observed at the surface of hydrolyzed starches after treatment. However, the principal feature is related to the increase of the granule crystallinity with increasing hydrolysis time. The results suggest that the starches treated by this new method are interesting candidates for application in the food industry if greater gelatinization resistance is required.

title: Production and thermal comfort of Nellore beef cattle finished in integrated crop-livestock systems

description: ABSTRACT The objective of this work was to evaluate pasture, performace, thermal comfort, and haematological parameters of Nellore cattle in the finishing phase in integrated crop-livestock systems with two tree densities (ICLF-1L= 196 ha -1 trees and ICLF-3L= 448 ha -1 trees) and in full sun (ICL). The forage mass morphological composition of the pasture average daily gain, weight gain per area, stocking rate of the animals were evaluated in summer and autumn, and the climatic variables of systems we evaluated at three different times, and haematological parameters of the animals (n= 60). The forage mass was higher in the ICL treatment and summer (P&lt;0.05). However, the reduction of the forage mass in the ILPFs systems did not interfere with the performance of the animals (P&gt;0.05). Ambient temperature, globe temperature and temperature and humidity index were better in shade treatments and in the morning, providing greater comfort to the animals, and was also confirmed by the lower globular volume of the bovines in ICL (P&lt;0.05). It is concluded that the systems with trees reduce the forage mass but this reduction does not alter the animals’ performance in the finishing phase. In addition, ICLFs improve the thermal comfort of the animals, however, this improvement was not enough to favor their performance.

title: Psychosocial factors at hospital work: experienced conditions related to job strain and effort-reward imbalance

description: Abstract Introduction: inadequate hospital work conditions and organization constitute psychosocial factors at work (PSFW) that trigger stress and may have negative outcomes for workers, patients and institutions. Objective: to evaluate the prevalence of PSFW and associated personal and occupational conditions among hospital workers. Methods: cross-sectional study with 1,795 workers from a hospital in São Paulo, Brazil. A self-administered form was used to evaluate demographic and occupational features and PSFW (questionnaires based on the Demand-Control and Effort-Reward models). Descriptive analysis and ordinal logistic regression of partial proportional odds were performed. Results: prevalence rates of conditions related to job strain were: 13.6% low risk, 73.0% intermediate risk and 13.4% high risk. Effort-reward imbalance prevalence rates were: 33.1% low imbalance, 31.3% moderate imbalance, 30.8% high imbalance and 4.8% non-answer. Individual and occupational features were associated with the occurrence of PSFW. Conclusion: the two models evaluate different aspects of the work activities and social insertion of individuals at work, and individual and occupational conditions were associated with PSFW. The results show that different issues should be considered when planning intervention to improve the psychosocial environment at work.

title: Cardol-Derived Organophosphorothioates as Inhibitors of Acetylcholinesterase for Dengue Vector Control

description: Aedes aegypti is the main vector of three neglected tropical diseases: dengue, zika and chikungunya. Dengue is under surveillance by health organizations worldwide due to the risk of epidemics. Since there is no specific treatment for dengue, most studies have focused on preventing the reproduction and/or development of the mosquitoes. We studied the larvicidal activity of five phosphates and phosphorothioates derived from cardol, one of the four main components of cashew nut shell liquid (Anacardium occidentale L.), at different concentrations. The organophosphorothioate derivatives were tested for their in vitro inhibitory potential against acetylcholinesterase (AChE). One compound, Cdl.i-dPS (median lethal concentration (LC50) = 0.8 ppm), was four times more efficient compared to an important commercial larvicide, Temephos (LC50 = 3.2 ppm), and showed greater AChE inhibition than its monosubstituted analogue and Temephos.

title: The role of gadoxetic acid-enhanced magnetic resonance cholangiography in the evaluation of postoperative bile duct injury: pictorial essay

description: Abstract Iatrogenic lesion of the bile ducts is a relatively common occurrence during liver surgery, increasing morbidity and mortality rates. T2-weighted magnetic resonance cholangiography and gadoxetic acid-enhanced functional magnetic resonance cholangiography (fMRC) with administration of hepatobiliary-specific contrast medium (gadoxetic acid) are fundamental to the diagnostic imaging approach in patients with such lesions. Here, we present a review of the literature and suggest an imaging approach to biliary tract injury, focusing on clinical cases in which fMRC had an impact on the decision-making process for the management of the affected patients.

title: Rectal prolapse in small ruminants: etiology, anesthetic and surgical techniques, and outcome in 12 animals - case report

description: ABSTRACT Nine ovine and three caprine with grade II intermittent or permanent rectal prolapse were treated, with the first report in caprine, according to the consulted literature. The clinical history was deeply explored with the clinical evaluation of the livestock. Among the causative factors identified were the inappropriate ventilation with high levels of dust and ammonia in the facilities, which was correlated to the high incidence of pneumonia and cough. The causative factors identified in the patients were overweight, pneumonia and cough, and, less predominately, verminosis and pregnancy. The treatment was based on manual reduction (T1) or rectal amputation (T2), under sacrococcygeal or lombossacral epidural anesthesia, with or without neuroleptic analgesia. The treatments were efficient in all patients; although there was recurrence in two animals, which needed the repetition of the treatment after their delivery to the farm. Based on the cases reported here, it can be concluded that the history and the livestock clinical evaluation are important to identify the primary causes, avoiding relapses. It also concluded that the surgical treatment and the anesthetic protocol used in the patients reported here were efficient and can be applied even under field conditions.

title: Bioclimatic zoning and trend analysis applied to broilers

description: ABSTRACT The objective of the present study was to establish the bioclimatic zoning by the temperature and humidity index (THI), considering a historical period and a future scenario, in order to represent the thermal environment for broiler breeding in the State of Minas Gerais. A historical series (1976 - 2014) of THI minimum, average and maximum calculated based on data from 48 conventional meteorological stations was used, belonging to the National Institute of Meteorology of the State of Minas Gerais. The analysis of the temporal series was based on the Mann-Kendall test and linear regression. A geostatistical analysis was also carried out to determine the comfort zoning of broilers as a function of the THI intervals. In this way, the THI spatial mapping methodologies and trend analysis for the prediction of a possible future climate scenario can help in the development of risk maps for monitoring thermal comfort of broilers, being indispensable in the planning of actions for the mitigation of the climatic change impacts on the productive chain of the State of Minas Gerais.

title: Ultrastructural changes detected using swept-source optical coherence tomography in severe vitreopapillary traction: a case report

description: ABSTRACT Vitreopapillary traction is an uncommon condition characterized by strong adhesion and the traction of the posterior hyaloid onto the optic disc and peripapillary retina, leading to optic disc elevation and visual loss. An 85-year-old man presented with a 6-month history of slow, progressive visual loss in the left eye along with optic disc edema. Swept-source optical coherence tomography B-scans revealed circumpapillary anterior-posterior persistent traction of dense vitreous strands onto the optic disc. Visual field examination demonstrated mild, generalized, diffuse sensitivity loss and blind-spot enlargement. A 25-gauge posterior vitrectomy was performed with posterior hyaloid separation from the optic disc, resulting in significant anatomical and visual improvement. In conclusion, swept-source optical coherence tomography aids in understanding the mechanism underlying visual loss in vitreopapillary traction. Moreover, posterior vitrectomy can effectively promote anatomical and visual improvements in these cases.

title: Performance and thermoregulation of lactating sows housed in different locations inside a shed with an evaporative cooling system in a tropical environment

description: ABSTRACT The effects of housing lactating sows at different locations in a shed with evaporative cooling system (ECS) on their thermoregulation and reproductive and productive performance of the sow and the litter in summer were determined. 34 females were used in the three lines of cages at these locations: near the pad cooling; in the middle of the shed and near the exhaust fans. The air temperature and the temperature and humidity index (THI) were lower near the pad cooling (22.38ºC, 71.84) than the middle (24.56ºC, 74.82) and near the exhaust fans (25.00°C, 75.62). Respiratory rate, rectal and surface temperatures were lower in sows near the pad cooling (43.67 breaths.min -1 , 38.40°C; 29.51°C) than in the center (52.04 breaths.min -1 ; 38.48ºC; 32.02ºC) and near the exhaust fans (56.38 breaths.min-1, 38.93ºC; 32.52ºC). The backfat thickness, the weaning-estrus interval and daily average consumption of the sows, number of weaning piglets, corporal mass and daily average gain of the piglets were not influenced by the location of housing in the shed. Lactating sows housed in the middle and near the exhaust fans in the ECS presented increased thermoregulation physiological variables, however, this did not impair the performance.

title: A New Electrochemical Platform Based on a Polyurethane Composite Electrode Modified with Magnetic Nanoparticles Coated with Molecularly Imprinted Polymer for the Determination of Estradiol Valerate in Different Matrices

description: A polyurethane composite electrode modified with magnetic nanoparticles (mag; Fe3O4) coated with molecularly imprinted polymers (MIPs) was developed for the electrochemical determination of estradiol valerate. Chemical and morphological analyses of the mag-MIP were performed using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), with the aim of characterizing this new material. The efficiency of adsorption of estradiol valerate by the mag-MIP was tested in binding experiments using an electrochemical method. For this, different electrodes (mag-MIP / graphite-epoxy composite (GEC), mag-non-imprinted polymer (NIP) / GEC, mag / GEC, and GEC) were evaluated by square-wave voltammetry (SWV). After 10 min at open circuit potential, increases in the current signal of 1.9, 2.1, and 3.0 times were obtained, comparing the electrochemical response of the mag-MIP / GEC sensor to the mag-NIP / GEC, mag / GEC, and GEC sensors, respectively. Under optimized conditions, the mag-MIP / GEC showed a linear concentration range for estradiol valerate of 5.0 × 10-7 to 7.5 × 10-4 mol L-1 and a limit of detection of 1.0 × 10-8 mol L-1. The proposed sensor was applied in the analysis of pharmaceutical, human urine, and river water samples. The recovery values determined using high performance liquid chromatography (HPLC)-UV and the electrochemical method were in agreement and were near 100%, demonstrating the reliability of the proposed method.
