Giant gouramy is a native fish to Indonesia and widely distributed in Sumatra, Kalimantan and Java. The aim of this study was to characterize the phenotype and kinship of Giant Gouramy from crosses between strains Jambi, South Kalimantan, and West Java (Tasikmalaya). This Research was conducted at the Giant gouramy Hatchery of Research Institute for Fish Breeding, Sukamandi, West Java. Analysis of morphological diversity of all crosses between varieties performed through morphometric measurements that have been determined based on a point benchmark of 16 haracteristics of the truss. Measurement data of each character crosses which have beenrelativized by standard length were analyzed using discriminant analysis and hierarchical cluster analysis. The result showed that Giant gouramy has low diversity coefficient values, ranging from 4 to13%. The highest coefficient of variance (CV) was found in the character of C3 (the tip of the anal fin-base of the tail fin), which ranges from 18-33% and the lowest in the character B5 (the base of the pelvic fin-tip of the dorsal fin) in the range of 2-4%. Based on discriminant analysis, males Giant Gouramy have more character differences than females. The closest kinship relationship is in hybrid of Tasikmalaya and Jambi (TJ) strain with of South Kalimantan and Tasikmalaya ( KT) which has a similarity level at 89.41%. However, the farthest kinship is in pure line of Tasikmalaya (TT) and Jambi (JJ) with the three other strains namely South Kalimantan and Jambi (KJ), Tasikmalaya and Jambi (TJ) and South Kalimantan and Tasikmalaya (KT) with a value of similarity of 53.93%.

Published: July 2018

African catfish, namely lele dumbo, is an economically important fresh water fish in Nusa Tenggara Barat. There are three strains of African catfish that are well distributed among farmers. Genetic information of three strain catfish stocks is needed in order to sustain their development program. Genetic variations of the three strains of catfish, i.e. Sangkuriang, Masamo, Paiton has been evaluated using RAPD markers. DNA genome was extracted using phenol-chloroform methods. DNA was amplified using 20 primers (OPA 1 – 20). The results showed that three of the 20 primers have good amplification products. There was no significant genetic differences among three strains of catfish analyzed (P>0.05). Genetic variation of three African catfish stocks ranges from low to middle value. The highest genetic variation is found in strain Masamo with heterozygosity of 0.273 (with 70% polymorphism loci), followed by Sangkuriang 0.189 (60%) and Paiton 0.147 (40%). Hybrid candidates of Masamo-Sangkuriang have eterozygosity ranges between 0.256 - 0.306 (with 66.6 7 – 73.77% polymorphism loci). Strain Masamo and Paiton has more close genetic relationship than among the both and Sangkuriang.

Currently, there is a national concern regarding to the decrease of milkfish production from ponds in North Java due to a low quality of milkfish seed produced by small scale hatcheries in Bali, which is the main producer of milkfish seed. The quality of seed is strongly related to the quality of eggs (fertility), while quality of eggs produced depends on the management of brood stocks carried out by the hatcheries. Growth rate and growth hormone profiles are some of the biological aspects that could be used as a basis/benchmark to evaluate quality level of milkfish seed reared in ponds. The aim of this experiment was to evaluate growth rate and growth hormone profile performance between selected G-2 seed and small scale hatcheries seed as control population the growth rate. Research on grow-out of milkfish seed was conducted at the IMRAD ponds facility in Pejarakan, using milkfish seed produced by small scale hatcheries as well as selected second-generation (G-2) seed, each with the density of 5000 seed/pond (1 pond=0.5 ha). The seeds were fed with dry pellet and reared for 5 – 6 months. The results showed that the seed produced with standard operational procedure (SOP) by small scale hatcheries were having longer (F hit. = 13.68 > F tabel 1%) and heavier body washt (F hit. = 18.98 > F tabel 1%) better than selected G-2 seed and small scale hatcheries seed without SOP with high growth hormone concentration (F hit. = 4.95 > F tabel 5%).
The effect of temperature on cadmium oxide (CdO) nanoparticles produced by synchrotron radiation in the human cancer cells, tissues and tumors
Authors: Heidari Alireza
Published: July 2018

In this work, the effect of temperature of the ablation environment on the properties of Cadmium Oxide (CdO) nanoparticles produced by synchrotron radiation is investigated. To produce nanoparticles, synchrotron radiation pulse with 1064 (nm) wavelength is used to emit Cadmium in the human cancer cells, tissues and tumors. All test parameters were kept constant and human cancer cells, tissues and tumors temperature was changed to produce samples at 20Â°C and 65Â°C. Then, ATRâ€“FTIR, XRD, TEM and UVâ€“Visible spectroscopy analyses were performed to investigate their properties. The results show that the size of nanoparticles is increased by increase in temperature of ablation environment. In addition, in the current experimental research, Gold (Au)â€“Cadmium Oxide (CdO) alloy is created at the size of nano. In this regard, same volume of Gold and Cadmium Oxide (CdO) solutions were mixed together and emitted by the synchrotron radiation pulse with wavelength of 532 (nm). The Gold and Cadmium Oxide (CdO) solutions have been produced, separately, using synchrotron radiation ablation process. To produce them, synchrotron radiation pulse with wavelength of 1064 (nm) and pulse width of 7 (ns) and repeating frequency of 5 (Hz) was used. The results show that synchrotron radiation emission with wavelength of 532 (nm) is an appropriate method for producing Gold compounds in the size of nano.Â Â

Estimating the Use of Higher-Order Theory of Mind Using Computational Agents
Authors: de Weerd Harmen , Diepgrond Denny , Verbrugge Rineke
Published: July 2018

When people make decisions in a social context, they often make use of theory of mind, by reasoning about unobservable mental content of others. For example, the behavior of a pedestrian who wants to cross the street depends on whether or not he believes that the driver of an oncoming car has seen him or not. People can also reason about the theory of mind abilities of others, leading to recursive thinking of the sort ‘I think that you think that I think…’. Previous research suggests that this ability may be especially effective in simple competitive settings. In this paper, we use a combination of computational agents and Bayesian model selection to determine to what extent people make use of higher-order theory of mind reasoning in a particular competitive game known as matching pennies. We find that while many children and adults appear to make use of theory of mind, participants are also often classified as using a simpler reactive strategy based only on the actions of the directly preceding round. This may indicate that human reasoners do not primarily use their theory of mind abilities to compete with others.
A Truncation Model for Estimating Species Richness
Authors: François Koladjo Babagnidé , Ohannessian Mesrob I. , Gassiat Elisabeth
Published: July 2018

We propose a truncation model for the abundance distribution in species richness estimation. This model is inherently semiparametric and incorporates an unknown truncation threshold between rare and abundant observations. Using the conditional likelihood, we derive a class of estimators for the parameters in this model by stepwise maximization. The species richness estimator is given by the integer maximizing the binomial likelihood, given all other parameters in the model. Under regularity conditions, we show that our estimators of the model parameters are asymptotically efficient. We recover Chaos lower bound estimator of species richness when the parametric part of the model is single-component Poisson. Thus our class of estimators strictly generalized the latter. We illustrate the performance of the proposed method in a simulation study, and compare it favorably to other widely-used estimators. We also give an application to estimating the number of distinct vocabulary words in French playwright Molière’s Tartuffe.
Contemporary Traditionalists and Reformists Iranian Jurists and the Subject of Human Rights
Authors: Goudarzi Masoumeh Rad , Najafinejad Alireza
Published: July 2018

The inability of traditional Shi’a jurisprudents to respond to the challenges in the field of human rights and the rights of religious minorities, which is rooted in the denial of human dignity and the emphasis on religious dignity, has led to the emergence of a new discourse among contemporary Shi’a jurisprudents in Iran in recent years. This group of jurists known as reformist jurists seeks to re-evaluate the jurisprudential laws, re-interpret the Shari’a and find a way out of the religion to reduce the existing conflict with the universal human rights standards. The opinions of this group of jurists, albeit criticized by the traditional scholars, have been welcomed by young clerics. To understand the main aspects of this jurisprudential dispute, two main questions have been considered by the researchers: What are the main principles of human rights in the thoughts of traditionalist and reformist jurists in Iran? And how differently have the reformist jurists conceptualized the subject of human rights? To answer these questions, the impact of traditional jurisprudents on the formulation of the current constitution of Iran is studied and the main differences between the views of traditional and modern jurists are evaluated.
Iconically modeling a demolition process in the photobook Palast Der Republik
Authors: Alves Vitral Letícia , Queiroz João
Published: July 2018

Palast der Republik, by the photographer Christoph Rokitta, is an independent photobook published in 2013 in Berlin. In the photobook different semiotic resources are coupled in order to iconically model the demolition of the homonymous building in Berlin. In opposition to the trivial notion of icon as sign that stands for its object in a relation of similarity, we analyze the photobook as an icon whose main feature is the possibility of discovering information about its object through its manipulation. This specific feature is calledoperational criterion for iconicity, and it stresses the inherent quality of icons of revealing information available through their manipulation and observation. Our aim is to describe and analyze the relations between semiotic resources in this photobook by exploring the operational criterion of iconicity, and models as epistemic artifacts. We are interested in how couplings between semiotic resources in the photobook can iconically model a spatio-temporal process.

Published: July 2018

Aneurysms of the temporal superficial artery (TSA) are very rare clinical entity. From 1861 to the present day, is described less than 200 cases. The most common cause of these aneurysms is so called blunt head trauma but there are described many cases of iatrogenic aneurysms, very rarely, aneurysms arise spontaneously. We report a case of 17-yearold patient with spontaneously formatting aneurysm of TSA. Three months prior to admission, he noticed the existence of tumefaction localized frontotemporal on the right side. MSCT angiography of blood vessels of the scalp showed an aneurysm on the frontal branch of TSA diameter of 15 mm. The aneurysm was resected with uneventful postoperative course. PH findings pointed to a true aneurysm. Treatment protocol for the aneurysms of the TSA include clinical monitoring, compression of the aneurysm, the injection of thrombin, endovascular treatment and surgical resection. Surgical resection has proven to be a safe and effective treatment modality and still is the method of choice.

Carotid atherosclerosis may be associated with neurosymptoms including cerebral infarction. IL-10 exerts atheroprotective effects, but its role in carotid disease is not fully defined. We aimed to investigate serum IL-10 levels in patients undergoing endarterectomy and their relation to the degree of carotid stenosis, plaque types and neurosymptoms.

Two hundred consecutive patients with atherosclerotic carotid stenosis and 29 healthy controls were enrolled in this study. Plaque types were classified according to AHA criteria. Serum IL-10 levels were determined by ELISA.

Patients undergoing endarterectomy had significantly higher circulating IL-10 levels (18.7 ± 3.2 pg/ml) in comparison with healthy controls (7.2 ± 1.8pg/ml; P =0.0001) and IL- 10 has good discriminatory efficacy between these two groups (ROC curve, AUC = 0.723, P=0.0001). Patients with < 70% and those with > 70% of carotid stenosis did not differ in terms of age, sex, cardiovascular risk factors except hypertension, neurosymptoms and AHA plaque types. Circulating IL-10 levels differed significantly among patients with different carotid plaque types (P = 0.002). Patients with uncomplicated plaques had significantly higher serum levels of IL-10 (23.0 ± 6.1 pg/ml) compared to those with complicated plaques (13.0 ±1.4 pg/ml, P=0.035) and IL-10 can differentiate patients between these two groups (ROC curve, AUC = 0.413, P= 0.035).

Our findings reveal an important role for IL-10 in carotid atherosclerosis. IL-10 might be a potential biomarker in discriminating patients with carotid disease from healthy controls. Decreased serum levels of IL-10 are related to complicated carotid plaques.
Epilepsy Detection Using DWT Based Hurst Exponent and SVM, K-NN Classifiers
Authors: Sharmila Ashok , Madan Saiby , Srivastava Kajri
Published: July 2018

Epilepsy is a typical neurological issue which influence the focal sensory system and can make individuals have seizure. It can be surveyed by electroencephalogram (EEG). A wavelet based HURST EXPONENT strategy is displayed for the analysis of epilepsy. This strategy deals with the nonlinear analysis of EEG signals. Discrete wavelet transform is used to disintegrate the original EEG signal into specific subbands. The hurst exponent of different sub-bands is employed and then fed into two classifiers, namely SVM and KNN. The highest classification accuracy obtained in the presented work is 99% for healthy subject data versus epileptic data is obtained by SVM. However, the corresponding accuracy between normal subject data and epileptic data using SVM is obtained as 99% and 93% for the eyes open and eyes shut conditions, respectively. The detailed analysis of the methodology and results has been discussed in the paper.
Utjecaj ratnih i poratnih migracija na demografsku sliku Grada Knina (1991. – 2011.)
Authors: Mrđen Snježana , Jurić Ana
Published: July 2018

U radu se analiziraju promjene u ukupnom kretanju broja stanovnika u naseljima Grada Knina u posljednja dva međupopisna razdoblja (1991. – 2001., 2001. – 2011.) te promjene u narodnosnoj strukturi stanovništva. Budući da je rat prouzročio prisilne migracije koje su odredile demografske procese na tom području, posebna pažnja pridaje se proučavanju migracijskih obilježja stanovništva. Rezultati analize pokazuju da su se najveće promjene u demografskoj slici toga područja dogodile u međupopisnom razdoblju 1991. – 2001. Obje komponente (prirodno i mehaničko kretanje) koje su bile negativne dovele su do znatnog pada broja stanovnika te do izrazitog smanjivanja autohtonog stanovništva. Posljedica toga je promjena narodnosne strukture. Predratno srpsko stanovništvo smanjeno je za više od tri četvrtine, a doseljavanje stanovništva iz ostalih dijelova Hrvatske te iz Bosne i Hercegovine dovelo je do prevage Hrvata. Unatoč pozitivnom migracijskom saldu u posljednjem međupopisnom razdoblju, u većini naselja, koje obuhvaća ovo istraživanje, nepovoljni demografski procesi, okarakterizirani negativnom prirodnom promjenom te demografskim starenjem stanovništva, upućuju na nastavak depopulacije koja će u nekim naseljima dovesti do demografskog izumiranja.

Published: July 2018

Objectives

The aims of this paper were to evaluate the levels of Vitamin D (VitD) in patients with heart failure (HF), compared to a control group, to assess the effects of VitD on HF outcome and to compare VitD measurement between LIAISON immunoassay and HPLC-MS-MS methods in this population.

Design and Methods

We collected clinical, biochemical and outcome data from 247 patients with HF and in a subgroup of 151 patients, we measured VitD both with LIAISON and HPLC-MS-MS.

Results

HF patients had statistically lower 25OHD levels (45.2 ± 23.7 nmol/L vs 58.2 ± 24.0 nmol/L, P < 0.001) and a statistically higher prevalence of VitD insufficiency (61.1% vs 39.5%, P < 0.001) and deficiency (24.7% vs 6.6%, P < 0.001), compared to healthy controls. There was a significant inverse relationship between baseline 25OHD and risk of HF-related death, with a HR of 0.59 (95% CI 0.37–0.92, P = 0.02), confirmed in a multivariate adjusted analysis. Kaplan–Meier survival analyses showed that VitD insufficiency was associated with reduced survival in HF patients (log rank P = 0.017). There was a good agreement between LIAISON and HPLC-MS-MS (Cohen’s kappa coefficient 0.70), but the prevalence of VitD insufficiency was significantly higher with the former compared to the latter method (58.3%, n = 88 vs 55.6%, n = 84, P < 0.001). LIAISON underestimated the 25OHD levels and showed a mean relative bias of −0.739% with 95% of limits of agreement (−9.00 to +7.52%), when compared to HPLC-MS-MS.

Conclusions

25OHD levels adequately measured by HPLC-MS-MS showed to be low in HF population and to be correlated with HF-related risk of death.

Published: July 2018

Introduction and Aim

The purpose of replacement therapy in adrenal insufficiency (AI) is mimicking endogenous cortisol levels as closely as possible: dual release hydrocortisone (DR-HC) has been introduced to replicate the circadian cortisol rhythm. Multiple daily saliva collections could be used to assess the cortisol rhythm during real life: our aim was to study the salivary cortisol profile in AI.

Materials and Methods

We prospectively evaluated, in an observational study, 18 adult outpatients with AI (11 primary and 7 secondary AI), switched from conventional treatment (conv-HC, 25 mg/day) to the same dose of DR-HC. We collected six samples of saliva in a day, measuring cortisol (F) and cortisone (E) with LC-MS/MS. Forty-three matched healthy subjects served as controls.

Results

F levels were similar in the morning (and higher than controls) in patients treated with conv-HC or DR-HC; otherwise F levels and exposure were lower in the afternoon and evening in patients with DR-HC, achieving a cortisol profile closer to healthy controls. Daily cortisol exposure, measured with area under the curve, was lower with DR-HC. Morning F and E presented sensitivity and specificity >90% to diagnose AI (respectively threshold of 3 and 9.45 nmol/L). Total cholesterol and HbA1c levels reduced with DR-HC.

Conclusions

Salivary cortisol daily curve could be used as a new tool to assess the cortisol profiles in patients treated with conv-HC and DR-HC. A lower daily cortisol exposure was achieved with DR-HC (despite the same HC dose), especially in the afternoon-evening.
Impact of MR on mature adipocytes in high-fat/high-sucrose diet-induced obesity

Published: July 2018

Active glucocorticoid levels are elevated in the adipose tissue of obesity due to the enzyme 11 beta-hydroxysteroid dehydrogenase type 1. Glucocorticoids can bind and activate both glucocorticoid receptor (GR) and mineralocorticoid receptor (MR), and pharmacological blockades of MR prevent high-fat diet-induced obesity and glucose intolerance. To determine the significance of MR in adipocytes, we generated adipocyte-specific MR-knockout mice (AdipoMR-KO) and fed them high-fat/high-sucrose diet. We found that adipocyte-specific deletion of MR did not affect the body weight, fat weight, glucose tolerance or insulin sensitivity. While liver weight was slightly reduced in AdipoMR-KO, there were no significant differences in the mRNA expression levels of genes associated with lipogenesis, lipolysis, adipocytokines and oxidative stress in adipose tissues between the control and AdipoMR-KO mice. The results indicated that MR in mature adipocytes plays a minor role in the regulation of insulin resistance and inflammation in high-fat/high-sucrose diet-induced obese mice.
mTOR Complex 1 Implicated in Aphid/Buchnera Host/Symbiont Integration
Authors: James Edward B , Feng Honglin , Wilson Alex C C
Published: July 2018

Obligate nutritional endosymbioses are arguably the most intimate of all interspecific associations. While many insect nutritional endosymbioses are well studied, a full picture of how two disparate organisms, a bacterial endosymbiont and a eukaryotic host, are integrated is still lacking. The mTOR pathway is known to integrate nutritional conditions with cell growth and survival in eukaryotes. Characterization and localization of amino acid transporters in aphids suggest the mTOR pathway as a point of integration between an aphid host and its amino acid-provisioning endosymbiont Buchnera aphidicola. The mTOR pathway is unannotated in aphids and unstudied in any nutritional endosymbiosis. We annotated mTOR pathway genes in two aphid species, Acyrthosiphon pisum and Myzus persicae, using both BLASTp searches and Hidden Markov Models. Using previously collected RNAseq data we constructed new reference transcriptomes for bacteriocyte, gut, and whole insect tissue for three lines of M. persicae. Annotation of the mTOR pathway identified homologs of all known invertebrate mTOR genes in both aphid species with some duplications. Differential expression analysis showed that genes specific to the amino acid-sensitive mTOR Complex 1 were more highly expressed in bacteriocytes than genes specific to the amino acid-insensitive mTOR Complex 2. Almost all mTOR genes involved in sensing amino acids showed higher expression in bacteriocytes than in whole insect tissue. When compared to gut, the putative glutamine/arginine sensing transporter ACYPI000333, an ortholog of SLC38A9, showed 6.5 times higher expression in bacteriocytes. Our results suggest that the mTOR pathway may be functionally important in mediating integration of Buchnera into aphid growth and reproduction.
Holes in the Plasma Membrane Mimic Torso-Like Perforin in Torso Tyrosine Kinase Receptor Activation in the Drosophila Embryo
Authors: Mineo Alessandro , Fuentes Esther , Furriols Marc , Casanova Jordi
Published: July 2018

Receptor tyrosine kinase (RTK) pathways play central roles in development, and, when abnormally activated, they can lead to pathological conditions, including oncogenesis. Thus, RTK activation, mediated by ligand binding, is under tight control, a critical step being the conversion of an inactive precursor into the active form of the ligand. A variety of mechanisms have been shown to be involved in this conversion; however, little attention has been paid to how mechanical phenomena may impinge on this process. Here we address this issue by studying Torso, an RTK activated at both poles of the Drosophila embryo at the blastoderm stage. Torso activation is induced by a cleaved form of Trunk, a growth factor-like protein, but it also requires the accumulation of the Torso-like (Tsl) protein at both ends of the blastoderm. Tsl is the only known protein in Drosophila bearing a membrane attack complex/perforin (MACPF) domain—a motif present in proteins involved in pore formation at cell membranes. However, while different hypotheses have been put forward to account for the function of Tsl in Torso receptor activation, little is known about its molecular role and whether it indeed contributes to membrane pore formation. Here, we show that mechanically induced holes in the Drosophila embryo can substitute for Tsl function. These results suggest that Tsl is required for an exchange between the interior of the Drosophila embryo and its surrounding milieu and that mechanically induced cell injuries may contribute to abnormal RTK activation.

Published: July 2018

Objectives

The purpose of the present study was to obtain knowledge for improvement of the housing and life among radiation decontamination workers by examining the effect of housing type on anxiety over lack of privacy.

Methods

This cross-sectional study comprised 544 male radiation decontamination workers in Fukushima Prefecture who anonymously answered self-administered questionnaires in 2013, including measurement of privacy anxiety, housing type, career change, social support, and sociodemographics. Chi-square tests and binary logistic regression analysis were used to evaluate the associations between these factors and anxiety over lack of privacy.

Results

The number of workers who had anxiety over lack of privacy was 93 (17.1%), and the number of workers who were living in owner-occupied housing, rental housing, company dormitories, and hotels was 165 (30.3%), 177 (32.5%), 168 (30.9%), and 34 (6.3%), respectively. The presence of anxiety was significantly associated with housing type (p <0.001), a career change (p = 0.005), and the location of the worker’s previous residence (p <0.001). Binary logistic regression analysis revealed that life in a company dormitory and a career change were separately associated with anxiety over lack of privacy (p <0.001 and p < 0.027, respectively).

Conclusions

We found that anxiety among radiation decontamination workers over lack of privacy increased if they lived in company dormitories or had changed careers to become a radiation decontamination worker. These findings demonstrate the need to improve occupational mental health management, with an intensive focus on the residential environment.

Data on four organic solvents (styrene, ethyl benzene, isopropyl alcohol and tetrachloroethylene) were obtained from recent publications and added to previously cited data for 10 organic solvents. Regression analysis was used for statistical evaluation.

Results and Discussion

The previously reported results obtained using 10 solvents were reproduced by the analysis with 14 solvents. Repeated randomized division of the 14 sets into two subgroups of equal size followed by statistical comparisons did not show a significant difference between two regression lines. This reproducibility suggests that the procedures used to estimate BOELs may be applicable across many solvents, and this may be of particular benefit for protecting the health of workers who work with skin-penetrating solvents.

Published: July 2018

Abstract In spite of advances in root canal therapy and better knowledge of pulpal and periapical inflammation, up 40% of endodontic patients report varying degrees of pain. The aim of this present study was to compare the effect of single preoperative dose of ibuprofen or dexamethasone on post-endodontic pain. Sixty volunteers were divided into three groups (n=20 per group): PL, placebo; IB, 400 mg of ibuprofen; and DE, 8 mg of dexamethasone. The primary outcome was the post-endodontic pain intensity measured with a numerical rating scale (4, 8, 12, 24, and 48 h). Secondary outcomes included number of anesthetic cartridges used and consumption of rescue medication. Data were analyzed by one-way ANOVA, chi-square and Kruskal-Wallis tests. There was no significant difference among groups (p>0.05) considering the pain intensity. Only 37% of IB group patients and 28% of DE group patients used some rescue medication. On the other hand, 74% of PL group patients mentioned the consumption of rescue medication; PL group had a statistically significant difference (p<0.05) in comparison with IB and DE groups. The number of anesthetic cartridges used had no statistically significant difference among the groups (p>0.05). Significant differences were not found in the reduction of pain intensity and the number of anesthetic cartridges used. Considering the consumption of rescue medication (secondary outcome), preoperative administration of Ibuprofen or dexamethasone reduces post-endodontic pain and discomfort in comparison with a placebo. Premedication with anti-inflammatory drugs drugs could be contributed to control of the post-endodontic pain, mainly in patients more sensible for pain.

Published: July 2018

ABSTRACT BACKGROUND: Schistosomiasis is an endemic health problem affecting about four million people. The hepatosplenic form of the disease is characterized by periportal hepatic fibrosis, pre-sinusoidal portal hypertension and splenomegaly. Liver function is preserved, being varices bleeding the main complication of the disease. The surgical treatment used in the majority of centers for the prevention of rebleeding is esophagogastric devascularization and splenectomy. Most authors reported better results with the association of surgical and postoperative endoscopic treatment. OBJECTIVE: The aim of this study was to compare the intra operative portal pressure decrease and esophageal varices behavior and rebleeding rates in patients submitted to surgical and postoperative endoscopic treatment after long-term follow-up. METHODS: A retrospective study of 36 patients with schistosomiasis with, at least, one previous bleeding from esophageal varices rupture submitted to esophagogastric devascularization and splenectomy, added to endoscopic varices postoperative treatment was performed. Patients were stratified according to the intra operative portal pressure decrease in two groups: reduction below and above 30%. Long-term varices presence, size and bleeding recurrence were evaluated. RESULTS: Regarding varices behavior, no significant influence was observed in both groups of portal pressure fall. Regarding bleeding recurrence, despite three times more frequent in the group with lower portal pressure fall, no significant difference was observed. All patients were submitted to postoperative endoscopic treatment. CONCLUSION: Esophageal varices banding, rather than portal pressure decrease, seems to be the main responsible factor for good results after combination of two therapies (surgery and endoscopy) for patients with portal hypertension due to schistosomiasis; further studies are necessary to confirm this hypothesis.

Published: July 2018

RESUMEN En este trabajo se obtuvieron mediante co-deposición electroforética (co-EPD) dos clases de “recubrimientos blandos”. En todos los casos se empleó como fase inorgánica un biovidrio y como fase orgánica poli(ɛ-caprolactona), PCL, comercial (PCLC) o sintetizada aniónicamente y modificada con anhídrido maleico (PCLS). Para asegurar un adecuado recubrimiento del sustrato metálico se optimizaron variables del proceso de deposición (diferencia de potencial y tiempo). Mediante técnicas de caracterización complementarias (FTIR, DSC) se corroboró la presencia de ambas fases en los recubrimientos estudiados. En los recubrimientos con PCLC comercial se observó mediante SEM la formación de aglomerados de mayor tamaño en comparación a los recubrimientos con PCL aniónica (PCLS), observándose en ambos casos un alto grado de recubrimiento del sustrato metálico y la ausencia de microfisuras. La bioactividad de los recubrimientos obtenidos se evaluó mediante ensayos de inmersión en fluido corporal simulado (SBF). Por difracción de rayos X se evidenció la formación de un precipitado de hidroxiapatita sobre la superficie de los recubrimientos y a través de microanálisis SEM-EDS se determinó que la hidroxiapatita presente en los recubrimientos con PCLS funcionalizada presentó una relación calcio/fósforo Ca/P ~ 1,78; valor muy próximo al estequiométrico en tejidos óseos.
Relationship of corrosion of concrete reinforcement to accelerated corrosion current
Authors: Yang Xiaoming , Wu Tianyu , Chen Yonglin
Published: July 2018

An experiment on artificially accelerated corrosion of reinforcing bars in reinforced concrete beams was carried out. The actual corrosion of the reinforcing bars was obtained after crushing the beams. The accelerated corrosion electrical circuit was analysed and simplified as a series–parallel circuit, the feasibility of which was verified by the calculated and actual current density in the reinforcing bars. Finally, curve fitting of the test data was carried out to modify an equation based on Faraday's law, which can be used to describe the relationship between current density and corrosion ratio during accelerated corrosion. The modified equation was found to be effective when verified against data from other experiments.
