Species- and substrate-specific stimulation of human plasma paraoxonase 1 (PON1) activity by high chloride concentration.
Authors: Bełtowski Jerzy , Wójcicka Grazyna , Marciniak Andrzej
Published: December 2019

Paraoxonase 1 (PON1), contained in plasma high-density lipoproteins, plays an important role in the protection of plasma lipoproteins and cell membranes from oxidative damage. Previous studies indicate that human PON1 is stimulated by high NaCl concentrations. The aim of this study was to characterize in more detail the effect of salts on serum PON1. Paraoxon-hydrolyzing activity of human serum was stimulated by 81.6% following the addition of 1 M NaCl. The effect of NaCl was dose-dependent between 0.5 and 2 M. PON1 activity toward phenyl acetate was reduced by 1 M NaCl by 55.2%. Both the paraoxon- and phenyl acetate-hydrolysing activity was slightly lower in heparinized plasma than in serum, but NaCl had similar stimulatory and inhibitory effects on these activities, respectively. In rat, rabbit, and mouse, NaCl reduced PON1 activity. KCl had a similar effect on human PON1 as NaCl. Sodium nitrite also stimulated human PON1 but much less effectively than chloride salts. In contrast, sucrose, sodium acetate and sodium lactate had no significant effect. NaBr was a less effective PON1 activator than NaCl, whereas the effect of NaJ was non-significant. The activity of human PON1 toward homogentisic acid lactone and gamma-decanolactone was unaltered by NaCl. These data indicate that: 1) high concentrations of chlorides stimulate human PON1 activity toward paraoxon but not other substrates, 2) PON1 is inhibited by Cl(-) in other mammalian species, 3) the potency of human PON1 activation by halogene salts increases with decreasing atomic mass of the halide anion.

Authors: Al-Khedhairy Abdulaziz A , Arfin Misbahul , Bin Dukhyil Abdul Aziz
Published: December 2019

Molecular cloning and sequencing of a cDNA encoding rabbit presenilin-1 (Ps1) fragment was performed by reverse transcription polymerase chain reaction (RT-PCR) using primers: 5'-GGA TGA GCA GCT AAT CTA TAC C-3' and 5'-TCC ATT CAG GGA GGT ACT TGA TA-3'. The cDNA fragment revealed 402 nucleotides. The sequence was well conserved and found to be 91, 90, 88, 87 and 78% homologous to that of human, lemur, rat, mouse and chicken, respectively. The cDNA translated into a 130 amino-acid protein fragment. The deduced amino-acid sequence was also well conserved in various species and exhibited 98% similarities with those of rat, lemur and human homologues. However, differences were noticed at residues 145, 168 and 212. This cDNA fragment is quite significant because it is the most conserved portion of Ps1 in various animals and encodes four transmembrane regions (TM2, 3, 4, 5) as defined in human Ps1. Moreover, it includes more than 50% of the sites at which substitutions have been reported in familial Alzheimer's disease (FAD). Therefore, it is suggested that the rabbit can be used as an experimental model for future studies on Ps1 and its physiological functions to work out possible pathways leading to FAD linked neurodegeneration.
Quando a imagem é corpo: modos de sobreviver à máquina colonial
Authors: Resende Fernando , Robalinho Roberto , Amaral Diego Granja
Published: December 2019

Este artigo parte dos vestígios de uma escrava africana enterrada na região portuária do Rio de Janeiro e do filme “Era o Hotel Cambridge” (Brasil, 2016), sobre uma ocupação no centro de São Paulo, com o objetivo de discutir como a imagem configura um corpo a partir de situações liminares. A proposta é observar a emergência intermitente das imagens e daquilo que é relegado à posição de resto, rastro, e vestígio na estrutura do poder colonial. Dos ossos humanos, que clamam um acerto com um passado escravagista, ao esqueleto de um edifício abandonado pela especulação e reinventado como corpo político por refugiados e sem-tetos brasileiros, a imagem é a instância que conduz as demandas políticas no tempo. É a insistência de uma memória marginalizada, violentada, mas que recusa o apagamento. Como gesto de criação, persistência e (r)existência, a imagem nos serve como instrumento analítico para pensar contextos pós-coloniais e suas sobrevivências.

Published: December 2019

Se analizaron morfológica y filogenéticamente diferentes aislados de Corynespora cassiicola obtenidos de jamaica (Hibiscus sabdariffa) y nueve malezas asociadas al cultivo. Los aislados fúngicos se dividieron en dos grupos: el grupo uno incluyó 37 aislados obtenidos de H. sabdariffa y ocho obtenidos de otros hospedantes como Solanum lycopersicum, Chromolaena odorata, Senna alata, Eugenia oerstediana, Passiflora viridiflora, Momordica charantia, Ricinus communis y Gossypium hirsutum; en este caso, las colonias predominantes fueron de color gris, textura densa y forma poligonal. El grupo dos, incluyó a dos aislados obtenidos de H. sabdariffa y uno de Hyptis suaveolens; en este grupo, las colonias fueron principalmente de color crema y café pálido, densas y redondeadas. El análisis comparativo con aislados de C. cassiicola de otros países mostró que los aislados del grupo uno referidos anteriormente se asociaron principalmente con aquellos aislados de la familia Solanaceae, mientras que los del grupo dos se relacionaron con los de la familia Cucurbitaceae. Para nuestro conocimiento este es el primer estudio sobre la caracterización morfológica y genética de C. cassiicola en México.

The objective of this paper is to describe the Validation process of a new MSc Programme in railway transport and logistics which has been designed within the RiFLE project. RiFLE stands for Rail Freight and Logistics Curriculum Development and is funded by the Erasmus programme of the European Commission. The innovative idea of RiFLE is that the courses developed will run in the participating institutions, and they will be compatible to allow the students to attend some of their modules in the other universities. Moreover the possibility of a joint programme and degree is currently under evaluation. In particular RiFLE developed 26 rail freight and logistics Subjects combined in four Curricula, each of them corresponds to the perspective of a student entering the Programme from one of the four participating Institutions. The Validation process of the four Curricula has been carried out against both the European Educational Standards for Mscs and Industry requirements, implementing a stepwise methodology. Validation against Standards has been performed developing an extensive overview of the existing educational standards for Master programmes in Europe and the guidelines on how to meet them. Validation against Industry requirements has been achieved through a Workshop, during which over 30 external experts of Academic Institutions and Companies active in the Rail and Logistic sectors expressed their judgment on the RiFLE Programme and gave suggestions for improvements.

Published: December 2019

Over the last few decades there has been an exponential growth in IT, motivating IT professionals and scientists to explore new dimensions resulting in the advancement of artificial intelligence and its subcategories like computer vision, deep learning and augmented reality. AR is comparatively a new area which was initially explored for gaming but recently a lot of work has been done in education using AR. Most of this focuses on improving students understanding and motivation. Like any other project, the performance of an AR based project is determined by the customer satisfaction which is usually affected by the theory of triple constraints; cost, time and scope. many studies have shown that most of the projects are under development because they are unable to overcome these constraints and meet project objectives. We were unable to find any notable work done regarding project management for augmented reality systems and application. Therefore, in this paper, we propose a system for management of AR applications which mainly focuses on catering triple constraints to meet desired objectives. Each variable is further divided into subprocesses and by following these processes successful completion of the project can be achieved.

The ICAR-Central Marine Fisheries Research Institute (ICAR-CMFRI) is the pioneer in developing the technology for cage fish farming in India . Cobia (Rachycentron canadum) grows relatively fast in cages and is very much suited for carrying out small scale mariculture to meet the alternate livelihood needs of fisher-folk. Mandapam Regional Centre of ICAR-CMFRI has developed the technology for breeding, seed production and farming of cobia in cages and organised training, and frontline/participatory demonstration programmes which have aided in creating awareness about the techno-economic viability of cage farming among the fisherfolk in Ramanathapuram District, Tamil Nadu. A survey was taken up among a sample of 75 members of fisher self help groups (SHGs) who had adopted cage farming of cobia, inorder to assess their perception and attributes about the technology as well as the constraints faced by them. The study found that fast growth rate of cobia, shorter culture period, good farm gate price, high market demand, ease of farming near the seashore and seed availability were the important attributes which attracted the fishermen groups to take up the farming. The innovations introduced by the fishers in cage farming technology were also documented. Majority of the fishers stated, non-availability of seed during peak stocking season, high cost of pellet feed, fluctuating cost of low value fishes which are used as feed for cobia and poaching as major constraints in cage farming.

This work provides data on the somatic growth and age of selected commercial fish species of the Cullera Coast, Spain. The biological information available that permits responsible fishing management of these species is relatively scarce. This study was conducted in the Bay of Cullera, Spain (39º 12’to 38º 59’N, and 0º 09’to 0º 15’W); and selected benthic fish species were analysed that are frequently fished by trammel nets (mesh size 28-76 mm) at a maximum depth of 30 m. Maturity , age and growth of 63 torpedoes, Torpedo torpedo (L., 1758), 115 red scorpionfish, Scorpaena scrofa Linnaeus, 1758, 280 red mullets, Mullus surmuletus Linnaeus, 1758, 139 stargazers, Uranoscopus scaber Linnaeus, 1758, and 476 Portuguese soles, Dagetichthys lusitanicus de Brito Capello, 1868 were analysed. The data obtained in this study revealed that 50% of individuals of all the species reached sexual maturity at a TL (total length) of 20.0-36.5 cm and at an age of 2-6 years. The von Bertalanffy growth equation derived were: TL=37.0 (1 - e(-0.2(t + 0.33))); TL =31.5(1 - e(-0.38(t + 0.54))); TL =35.5(1 - e(-0.2(t + 2.08))); and TL =34.3(1 - e(-0.14(t + 2.16))) for S. scrofa, M. surmuletus; U. scaber and D. lusitanicus respectively.

Published: December 2019

The tiger toothed croaker Otolithes ruber (Schneider, 1801) of the family Sciaenidae is a demersal fish that contributes significantly to the marine landings of India. To identify stock units of O. ruber based on body shape morphometry, truss network analysis was carried out based on specimens collected from four selected locations, two each from east coast (Digha and Chennai along Bay of Bengal) and the west coast (Cochin and Ratnagiri along Arabian Sea) of India. A total of 20 truss distances along the fish surface, including head, mid body and posterior region were measured and transformed measurements were subjected to factor analysis and discriminant function analysis. The bivariate plot score of factor analysis indicating two distinct stocks on both the coasts may be the consequence of geographical isolation and different environmental conditions along the Bay of Bengal (east coast) and Arabian Sea (west coast). The Ratnagiri and Cochin population showed considerable mixing which indicated the presence of a unit stock along the west coast. However, existence of strong morphometric differentiation between Digha and Chennai populations indicated two separate spawning populations in the Bay of Bengal. In the cross-validation of Discriminant function analysis, the most well classified group was Digha population (97.85%). The present study suggests the possible existence of three stocks of O. ruber, one in west coast (Cochin and Ratnagiri) and two in east coast (Digha and Chennai) which can be considered while formulating effective management strategies for the species.

Authors: Upadhyay Aurobinda , Felix N. , Prabu E.
Published: December 2019

Evaluation of the efficiency of rapeseed meal (RSM) as an alternative protein source by replacing soybean meal (SBM) in the diets of GIFT strain of Nile tilapia Oreochromis niloticus was carried out in cages installed at Poondi Reservoir, Tamil Nadu, South India. Five isonitrogenous (30% protein) and isolipidic (7% lipid) diets were formulated by incorporating RSM protein by replacing SBM protein at 0 (control diet), 25, 50, 75 and 100% levels (0RSM, 25RSM, 50RSM, 75RSM and 100RSM). Each diet was fed to two replicate groups of GIFT tilapia with a mean initial weight of 20.38 ± 0.07 g for 60 days in cages. GIFT tilapia fishes fed with 75RSM diet attained maximum percentage weight gain, PWG (590.89 %), maximum specific growth rate, SGR (3.22), best feed conversion ratio, FCR (1.03) and maximum protein efficiency ratio, PER (3.23) among the treatments. The fishes fed with 0RSM, 50RSM and 100RSM diets showed no significant difference (p>0.05) in mean weight gain, MWG, SGR, FCR and PER. No significant difference in hepatosomatic index, HSI was found among the fishes fed with 0RSM, 75RSM and 100RSM diets. There was no significant difference (p>0.05) observed in survival between treatments. The whole body proximate composition (moisture, protein, lipid and ash) of GIFT tilapia did not differ significantly (p>0.05) among the treatments. It was concluded that, rapeseed meal can completely (100%) replace soybean meal protein in the diets of cage cultured GIFT tilapia in reservoir, without compromising growth, feed conversion ratio and whole body composition.
Overview of Naturally Occurring Asbestos in California and Southwestern Nevada
Authors: Bailey R. Mark
Published: December 2019

Naturally occurring asbestos (NOA) is being discovered in a widening array of geologic environments. The complex geology of the state of California is an excellent example of the variety of geologic environments and rock types that contain NOA. Notably, the majority of California rocks were emplaced during a continental collision of eastward-subducting oceanic and island arc terranes (Pacific and Farallon plates) with the westward continental margin of the North American plate between 65 and 150 MY BP. This collision and accompanying accretion of oceanic and island arc material from the Pacific plate onto the North American plate, as well as the thermal events caused by emplacement of the large volcanic belt that became today's Sierra Nevada mountain range, are the principal processes that produced the rocks where the majority of NOA-bearing units have been identified.
Enhancement of Aeribacillus pallidus lipase production through optimization of medium composition using Box behnken design and its application in detergents formulations
Authors: KTATA Ameni , aida karray , Mnif Ines , Sayari adel , BEZZINE Sofiane
Published: December 2019

Background : Alkaline, thermostable bacterial lipases are largely used in detergent applications, since they substitute the use of synthetic detergents which are known to cause substantial environmental problems. These enzymes based detergent are eco friendly and produce a waste water with low level of COD (Chemical Oxygen Demand). In the present study, we investigated a newly isolated Aeribacillus pallidus strain produces, without induction, a novel halophilous, thermo-alkaline and detergent- tolerant lipase.
Results: Considerable interest has been given to this lipase by the improvement of its catalytic activity through the optimization of the pH, the (C/N) ratio and the inoculums size, using the response surface methodology based on the Box-Behnken Design of experiments. A total of 16 experiments were conducted, and the optimized pH, (C/N) ratio and inoculums size were 10, 1 and 0.3 respectively. The results of the analysis of variance (ANOVA) test indicated that the established model was significant (p value < 0.05).
Conclusions: The optimization of the production conditions leads to 6.68-fold of increase in the catalytic activity with a maximum of 68 U/mL. All in all, the lipase of Aeribacillus pallidus could be considered as a potential candidate to be incorporated in detergent formulations since it shows a good stability towards detergents and wash performance.
Efficacy of ultrasound-guided rectus sheath block, butorphanol for single-incision laparoscopic cholecystectomy: A prospective, randomized, clinical trial
Authors: Fu Huimin , Zhong Chaochao , Gao Yongtao , Xu Xingguo
Published: December 2019

Background: Whether rectus sheath block (RSB) combined with butorphanol can relieve incisional pain and visceral pain in patients undergoing single-incision laparoscopic cholecystectomy (SILC) remains unknown. The goal of this study was to assess the efficacy of ultrasound-guided bilateral RSB, and butorphanol for postoperative analgesia in patients undergoing SILC.Methods: All 116 patients who met the criteria were randomly divided into four groups: group I, (n=29) general anaesthesia combined with patient-controlled intravenous analgesia (PCIA) (sufentanil 1 µg/ml); group II, (n=29) general anaesthesia combined with PCIA (butorphanol 0. 08 µg/ml); group III, (n=29) ultrasound-guided RSB (ropivacaine 100 mg) combined with PCIA (sufentanil 1 µg/ml); and group IV, (n=29) ultrasound-guided RSB (ropivacaine 100 mg) combined with PCIA (butorphanol 0.08 µg/ml). Outcomes included visual analogue scale (VAS) scores (0-10) of incisional pain (defined as superficial pain on the abdominal wall) and visceral pain (defined as deep, dull pain within the abdomen) at rest and during cough at 2,6,12 and 24 h postoperatively, the dose of butorphanol and sufentanil, the number of PCIA presses, the length of hospital stay and the incidence of postoperative adverse events.
Results: Both the rest and cough incisional pain scores were lower during the first 2 and 6 h in group Ⅲ than in group Ⅰ (P＜0.05). Similarly, scores in group Ⅳ were significantly lower than those in group II (P＜0.05). Patients in group I needed more butorphanol as a rescue analgesic for pain relief than did those in group III, and patients in group IV needed less butorphanol as a rescue analgesic for pain relief than did those in group II. From the above pairwise comparisons, it is clear that groups III and IV had lower VAS scores. The VAS scores for visceral pain were lower in group II at 2, 6 and 12 h after surgery than in group I and lower in group IV than in group Ⅲ. Overall, ultrasound-guided RSB combined with PCIA (butorphanol 0. 08 µg/ml) performed the best.
Conclusions: Ultrasound-guided RSB combined with butorphanol can provide sufficient pain treatment after SILC than can general anaesthesia combined with sufentanil.

Background: The tree peony is an important ornamental plant with many cultivars and rich fragrances. The scents released from the flowers of various tree peony cultivars might impose different influences on psycho-physiological responses, which seem to be the gap in the present research.Methods: We investigated psycho-physiological responses of 80 students (23.9±2.25 years old) to the olfactory stimulation by the four types of tree peony fragrances, including the phenolic scent (PS), rose scent (RS), woody scent (WS), and lily of the valley scent (LVS). The present study assessed autonomic parameters such as heart rate (HR) and heart rate variability (HRV) to determine the arousal levels of the autonomic nervous system. Psychological evaluation was carried out using the Profile of Mood States (POMS) and semantic differential methods (SDM). Electroencephalography (EEG) was recorded during tree peony fragrance inhalation periods compared with control conditions.Results: The students exhibited significantly higher parasympathetic nervous activities, but significantly lower sympathetic nervous activities and heart rates after inhaling tree peony fragrances. The four kinds of tree peony fragrances induced significantly less negative and more vigorous moods, and obtained better scores in subjective evaluation, especially the rose scent. Furthermore, the analysis of EEGs showed a remarkable increase in the power of low alpha (8-10 Hz), high alpha (10-12 Hz), and theta (4-7 Hz) waves.Conclusions: Our studies demonstrated that a short olfactory stimulation with the four peony scents would be not only a promising therapeutic method for improving physiological function but also an effective psychological relaxation strategy for the participants.

Background: Epidemiologic studies of Oral and Maxillofacial lesions (OMLs) are rare compared with the studies of caries and periodontal diseases. It is fundamental to promote early diagnosis and provide appropriate health programs. This study was to investigate the prevalence and distribution of histologically confirmed OMLs in Sana’a.Methodology: The documented records of all patients with OMLs were recovered from the biggest histopathology laboratories that provide biopsy analysis in Sana'a Yemen, for a period of six years (2013 to 2018). This multicenter retrospective study was conducted on 1376 oral and maxillofacial biopsied lesions. The clinico-pathologic data were extracted from the histopathology reports which included age, gender, nature of specimen, site of lesion, clinical appearance and histopathological diagnosis. Descriptive analysis, Chi squared test, and binary logistic regression were performed.Results: Regarding malignant lesions, the most prevalent lesions among males and females was squamous cell carcinoma; OSCC (226; 33.0% and 214; 30.9%; respectively). Followed by undifferentiated pleomorphic sarcoma which were five cases (0.7%) for males and 6 cases (0.9%) for females. Most of the cases (43.8%) diagnosed as OSCC were in the age group older than 40 years old. At this age group, the second most prevalent lesions were Adenocarcinoma and Adenoid cystic carcinoma (0.7% and 0.6%; respectively). The results of the regression analysis show that the site of the lesion (OR; 0.6, CI; 0.51-0.81; P= 0.00) and age of the patient (OR; 4.17, CI; 5.22-5.41; P=0.00) were the independent factors of malignancy of oral lesions.Conclusion: The present study showed high prevalence of malignant and premalignant oral mucosal lesions. The data from this study highlighted the need for dental public health intervention programs for early detection of oral cancer among Yemeni population by dental practitioners. As well as the importance of education of the general population in regards to risk factors of OMLs.

BACKGROUND General practitioners (GPs) are the major first-line care players of the management of type 2 diabetes, in France. In addition to a well-balanced diet, physical activity (PA) appears as a necessary non-medicinal therapy in its own right. However, GPs emphasize several obstacles to its prescription, in particular due to their lack of knowledge on its practical modalities. The aim of this study is to evaluate the practices, the barriers and the factors favoring the prescription of physical activity in type 2 diabetic patients by GPs in French Guiana.METHOD: A cross-sectional descriptive study was conducted in the form of a questionnaire, designed to interview 152 French Guiana GPs, to describe their practice in prescribing physical activity (PA) in type 2 diabetic patients. RESULTS: The oral or written prescription of physical activity as a non-medicated therapeutic choice in the management of type 2 diabetes is practiced by 74% of the French Guiana GPs, on an oral mode, for most of them. However, only 37% of doctors responded to apply the content of the recommendations of the French National Authority for Health and decree, indeed only one third knew about it. GPs convinced of the interest of PA and aware of its recommendations in this area, prescribed more PA than others. The majority of physicians are interested in PA training, but only 11% are actually trained in this practice. The lack of structure adapted to the practice of PA and of awareness of the interest of PA in their patients’ metabolic pathology appeared as the main obstacles to the prescription. According to 55% of physicians surveyed, a compensation by social security of the costs related to the prescription would improve the adherence to the practice of PA.CONCLUSIONS: It appears important to develop the training of the GPs, reception facilities adapted to where to refer patients, and collaborations between the various actors within the framework of a sport-health device. In addition, therapeutic patient education (TPE) is to be developed in order to improve patient compliance and adherence to sport-health programs.

Background: Healthy eating plays a vital role in the management of metabolic risk factors, such as diabetes, hypertension, and dyslipidemia. The aim of this study was to investigate the factors associated with healthy eating among people with cardiovascular metabolic risk factors. Method: This study was a mixed method research (qualitative and quantitative). In the qualitative phase, 50 people who had at least a metabolic risk factor and referred to the Diabetes Centers of Karaj, Iran were interviewed based on PRECEDE framework to explain the causes of following/not following healthy eating. In the quantitative phase, first, we developed a questionnaire based on the findings of the qualitative phase, and its validity and reliability was assessed. Then 450 samples completed the questionnaire in order to identify factors related to healthy eating. The qualitative data analysis was done using directed content analysis. In addition, SPSS ver.17 and AMOS ver.18 software were used to analyze the quantitative data. Results: The results of quantitative part showed only 51.07% of participants followed healthy eating behaviors. Both the findings of the quantitative and qualitative indicated that predisposing factor was the most important determinant of healthy eating behaviors. There was a significant relationship with large effect size between predisposing factor and healthy eating behaviors (β=1, P=0.001). Among predisposing factors, self-efficacy (β=0.49, P=0.001) and perceived barriers (β=- 0.33, P=0.001) were the most significant predictors. However, the findings of quantitative and qualitative phases did not confirm each other for enabling and reinforcing factors. This means in the qualitative phase, enabling factor was perceived as a deep structural determinant of healthy eating, but in the quantitative phase, reinforcing factor (β=0.67, P=0.001) was reported as a significant social predictor. Conclusion: Although personal determinants were the most dominant determinants of healthy eating behaviors, not sufficient to explain eating behaviors. Therefore, social and structural factors have to be considered for promotion of healthy eating behaviors.

Background The short physical performance battery (SPPB) has played an important role in establishing a linkage between body function and health. Aims The aim of this study was to evaluate the predictive value of the SPPB summary score and its three components for screening prolonged hospitalization for coronary artery bypass grafting (CABG) in older patient candidates. Methods This study included 188 consecutive elderly patients (aged ≥ 60 years) undergoing elective CABG surgery and all the patients were assessed for SPPB. Stepwise regression was employed to analyze the association of postoperative length of hospital stay (LOS) with SPPB. The validity of SPPB scores were assessed by ROC curves to analyze the sensitivity and specificity for identifying elderly patients with prolonged hospitalization. ResultsAlthough SPPB and three components of SPPB all were independent risk factors of prolonged hospitalization, only the SPPB summary score and the 4-meter gait speed components showed good discriminative capabilities. A SPPB summary score cutoff of 10 provided the best accuracy for identifying prolonged hospitalization. The net benefit of model 2 (Model 1 combined with SPPB cut-off score) was better than that of the model 1 that had threshold probabilities of 30%–100%. Conclusions This study provided evidence for the clinical utility of the SPPB summary score and 4MGS test for prolonged hospitalization in elderly patients undergoing CABG. These tests also showed potential as a screening test for identifying elderly patients undergoing CABG who are at risk of prolonged hospitalization mobility.
