Neither Preconceptional Weekly Multiple Micronutrient nor Iron Folic Acid Supplements Affect Birth Size and Gestational Age Compared with a Folic Acid Supplement Alone in Rural Vietnamese Women: A Randomized Controlled Trial.
Venue: The Journal of nutrition

Maternal nutritional status before and during early pregnancy plays a critical role in fetal growth and development. The benefits of periconception folic acid (FA) supplementation in the prevention of neural tube defects is well recognized, but the evidence for preconception micronutrient interventions for improving pregnancy outcomes is limited.  This study aimed to evaluate whether preconception supplementation with weekly iron and folic acid (IFA) or multiple micronutrients (MMs) improves birth outcomes compared with FA alone.  We recruited 5011 women of reproductive age in a double blind, randomized controlled trial in Vietnam and provided weekly supplements containing either 2800 mg FA, 60 mg Fe and 2800 mg FA (IFA) or the same amount of FA and iron plus other MMs until they conceived (n 1813) All pregnant women received daily IFA through delivery, and were followed up for birth outcomes, including birth weight, gestational age, preterm delivery and small for gestational age (SGA) Group comparisons were done with the use of ANOVA or chi square tests for both intention to treat (n 1599) and per protocol analyses (women consumed supplements =26 wk before conception; n 824) Effect modification by baseline underweight or anemia status was tested with the use of generalized linear models.  The mean age of the women was 26 y, 30% were underweight, and <10% were nulliparous. The groups were similar for most baseline characteristics. The mean SD duration of the preconception intervention was 33 25 wk and compliance was high >90% Infants born to the 3 groups of women did not differ (P 0.05) on mean SD birth weight (3076.8 444.5 g) or gestational age (39.2 2.0 wk) or prevalence of SGA (12% low birth weight (5% and preterm delivery (10% There were no significant differences in women who consumed supplements =26 wk before conception or by baseline underweight or anemia.  Weekly supplementation with MMs or IFA before conception did not affect birth outcomes compared with FA in rural Vietnamese women.
Maternal sodium butyrate supplement elevates the lipolysis in adipose tissue and leads to lipid accumulation in offspring liver of weaning age rats
Venue: Lipids in Health and Disease

BackgroundSodium butyrate (SB) is reported to regulate lipid metabolism in mammals, and the relationship between maternal nutrition and offspring growth has drawn much attention in the last several years.MethodsTo elucidate the effects of maternal dietary SB supplementation on hepatic lipid metabolism in weaning rats, we fed 16 primiparous purebred female SD rats either a chow diet or a 1 sodium butyrate diet throughout pregnancy and lactation. At weaning age, samples of the maternal subcutaneous adipose tissue and offspring liver were taken. The serum indexes and expressions of proteins related to lipid metabolism were detected in the mother and offspring, respectively.ResultsThe results showed that the maternal SB supplement increased the concentration of non esterified fatty acid (NEFA) in the maternal and offspring serum (P 0.05) Total cholesterol (Tch) increased significantly in the weaning rat serum (P 0.05) Maternal adipose tissue from the SB supplemented rats showed higher content of protein G coupled protein (GPR43) and protein kinase A (PKA) (P 0.05) The expression of protein adipose triglyceride lipase (ATGL) and of total and phosphorylated hormone sensitive lipase (HSL) in the maternal adipose tissue increased significantly (P 0.05) compared to the control group. However the proteins related to lipogenesis showed no significant changes. Moreover, the concentration of triglyceride in the offspring liver increased significantly, and this likely resulted from an increase in the levels of fatty acids binding protein (FABP) and fatty acid translocase (CD36) protein (P 0.05) SB exposure during pregnancy and lactation increased the hepatic total cholesterol (Tch) content (P 0.01) which was related to a significantly up regulated offspring hepatic expression of low density lipoprotein receptor (LDLR) protein (P 0.05).ConclusionThese results indicate that a maternal SB supplement during pregnancy and the lactation period promotes maternal fat mobilization, which may result in fatty acid uptake and lipid accumulation in the liver of the offspring.
NCBI prokaryotic genome annotation pipeline
Venue: Nucleic acids research

Recent technological advances have opened unprecedented opportunities for large scale sequencing and analysis of populations of pathogenic species in disease outbreaks, as well as for large scale diversity studies aimed at expanding our knowledge across the whole domain of prokaryotes. To meet the challenge of timely interpretation of structure, function and meaning of this vast genetic information, a comprehensive approach to automatic genome annotation is critically needed. In collaboration with Georgia Tech, NCBI has developed a new approach to genome annotation that combines alignment based methods with methods of predicting protein coding and RNA genes and other functional elements directly from sequence. A new gene finding tool, GeneMarkS+ uses the combined evidence of protein and RNA placement by homology as an initial map of annotation to generate and modify ab initio gene predictions across the whole genome. Thus, the new NCBI's Prokaryotic Genome Annotation Pipeline (PGAP) relies more on sequence similarity when confident comparative data are available, while it relies more on statistical predictions in the absence of external evidence. The pipeline provides a framework for generation and analysis of annotation on the full breadth of prokaryotic taxonomy. For additional information on PGAP see https:/www.ncbi.nlm.nih.gov/genome/annotation_prok/ and the NCBI Handbook, https:/www.ncbi.nlm.nih.gov/books/NBK174280/
Consumer acceptance of a quick response (QR) code for the food traceability system: Application of an extended technology acceptance model (TAM)
Venue: Food research international

The objectives of this study are to apply the TAM using the addition of perceived information to individuals' behavioral intention to use the QR code for the food traceability system; and to determine the moderating effects of food involvement on the relationship between perceived information and perceived usefulness. Results from a survey of 420 respondents are analyzed using structural equation modeling. The study findings reveal that the extended TAM has a satisfactory fit to the data and that the underlying dimensions have a significant effect on consumers' intention to use the QR code for the food traceability system. In addition, food involvement plays a significant moderating function in the relationship between perceived information and perceived usefulness. The implications of this study for future research are discussed.
Smart Contract Templates: foundations, design landscape and research directions
Venue: ArXiv

In this position paper, we consider some foundational topics regarding smart contracts (such as terminology, automation, enforceability, and semantics) and define a smart contract as an automatable and enforceable agreement. We explore a simple semantic framework for smart contracts, covering both operational and non operational aspects, and describe templates and agreements for legally enforceable smart contracts, based on legal documents. Building upon the Ricardian Contract, we identify operational parameters in the legal documents and use these to connect legal agreements to standardised code. We also explore the design landscape, including increasing sophistication of parameters, increasing use of common standardised code, and long term research.
Smart Contract Templates: essential requirements and design options
Venue: ArXiv

Smart Contract Templates support legally enforceable smart contracts, using operational parameters to connect legal agreements to standardised code. In this paper, we explore the design landscape of potential formats for storage and transmission of smart legal agreements. We identify essential requirements and describe a number of key design options, from which we envisage future development of standardised formats for defining and manipulating smart legal agreements. This provides a preliminary step towards supporting industry adoption of legally enforceable smart contracts.
TruthDiscover: A Demonstration of Resolving Object Conflicts on Massive Linked Data
Venue: ArXiv

Considerable effort has been made to increase the scale of Linked Data. However, because of the openness of the Semantic Web and the ease of extracting Linked Data from semi structured sources (e.g. Wikipedia) and unstructured sources, many Linked Data sources often provide conflicting objects for a certain predicate of a real world entity. Existing methods cannot be trivially extended to resolve conflicts in Linked Data because Linked Data has a scale free property. In this demonstration, we present a novel system called TruthDiscover, to identify the truth in Linked Data with a scale free property. First, TruthDiscover leverages the topological properties of the Source Belief Graph to estimate the priori beliefs of sources, which are utilized to smooth the trustworthiness of sources. Second, the Hidden Markov Random Field is utilized to model interdependencies among objects for estimating the trust values of objects accurately. TruthDiscover can visualize the process of resolving conflicts in Linked Data. Experiments results on four datasets show that TruthDiscover exhibits satisfactory accuracy when confronted with data having a scale free property.
LogProv: Logging events as provenance of big data analytics pipelines with trustworthiness
Venue: 2016 IEEE International Conference on Big Data (Big Data)

Provenance is information about the origin and creation of data. In data science and engineering, such information is useful and sometimes even critical. In spite of that, provenance for big data is under explored due to the challenges from the 'Vs' of big data. In data analytics, users need to query history, reproduce intermediate or final results, tune models, and adjust parameters in runtime for making data driven decisions. In addition, users need to evaluate data and pipeline trustworthiness. Towards realising these functionalities for big data provenance, we propose a solution, called LogProv, which needs to renovate data pipelines or even some of big data software infrastructure to generate structured logs for pipeline events, and then stores data and logs separately. The data are explicitly linked to the logs, which implicitly record pipeline semantics. Semantic information can be retrieved from the logs easily since the logs are well defined and structured beforehand. We implemented LogProv in Apache Pig, and adopted ElasticSearch to provide query service. In this paper LogProv is evaluated in a Hadoop ecosystem hosted by a cloud and empirically case studied. The results show that LogProv is efficient since the performance overhead is no more than 10% the query can be responded within 1 second, the trustworthiness is marked clearly, and there is no impact on the data processing logic of original pipelines.
Suboptimal Anatomy of Metamorphic Manipulators Based on the High Rotational Dexterity

This paper presents a method for the task based determination of the suboptimal anatomy of a metamorphic manipulator considering tasks with varying orientation of the end effector. A performance index representing the orientation dexterity along the rotational motion of the end effector based on max min of the rotational manipulability is formulated. In addition, a method based on the screw motion and dual vectors representation is proposed for the determination of the Denavit Hartemberg (D H) parameters of each metamorphic link between two successive active joints and the relative homogeneous transformation matrix as a function of the pseudo joint angles. Thus the dependence of the kinematics of the manipulator and of the performance index on the pseudojoint angles is determined to be used in the searching of the sub optimal anatomy for the given task, since in metamorphic manipulators each anatomy of a given structure is defined parametrical by the pseudojoint angle values. The proposed approach is tested and demonstrated using a metamorphic manipulator structure with six active joints and four pseudojoints. The rotational velocity performance between the sub optimal and an arbitrary anatomy is compared and discussed.
Medical Expulsive Therapy Following Shock Wave Lithotripsy in Ureteral Calculi: An Effective Approach for the Improvement of Health Related Quality of Life
Venue: Urologia Internationalis

To evaluate the possible effects of medical expulsive therapy (MET) on the health related quality of life (HRQOL) of patients undergoing shock wave lithotripsy (SWL) for ureteric stones.  Eighty patients treated with SWL for ureteric stones were included in this study. Patients were divided into 2 groups; Group 1 received medical therapy only for colic pain and Group 2 received MET in addition to medical therapy. Patients requiring DJ stenting and auxiliary measures after SWL procedure were excluded. The remaining 54 patients were further evaluated (Group 1: n 26, Group 2: n 28) and followed up during the 4 week period for analgesic requirement, number of renal colic attacks, emergency department (ED) visits and the HRQOL scores by using EQ 5D index and EQ 5D visual analogue scale (VAS) values.  During the 4 week follow up period, cases undergoing SWL only required significantly higher amount of analgesics. In addition to the lower number of renal colic attacks and ED visits, EQ 5D index and EQ 5D VAS values also demonstrated higher mean values in patients undergoing SWL MET.  In addition to the increased spontaneous stone passage rates, MET following SWL for ureteral calculi could increase the HRQOL scores by lowering the number of both renal colic attacks and ED visits along with decreased analgesic need.
Medical ozone therapy reduces shock wave therapy induced renal injury
Venue: Renal failure

Extracorporeal shock wave (ESW) lithotripsy is the preferred treatment modality for uncomplicated kidney stones. More recently free oxygen radical production following ESW application has been considered to be crucial in shock wave induced renal damage. It has been shown that ozone therapy (OT) has ameliorative and preventive effects against various pathological conditions due to increased nitro oxidative stress. In current study, we aimed to evaluate the efficacy of OT against ESW induced renal injury.  Twenty four male Sprague Dawley rats were divided into three groups: sham operated, ESW, and ESW OT groups. All groups except sham operated group were subjected to ESW procedure. ESW OT group received 1 mg/kg/day of oxygen/ozone mixture intraperitoneally at 2 h before ESW, and OT was continued once a day for consecutive three days. The animals were killed at the 4th day, and kidney tissue and blood samples were harvested for biochemical and histopathologic analysis.  Serum ALT and AST levels, serum neopterin, tissue nitrite/nitrate levels, and tissue oxidative stress parameters were increased in the ESW group and almost came close to control values in the treatment group (p 0.05, ESW vs. ESW OT) Histopathological injury scores were significantly lower in treatment group than the ESW group (p 0.05, ESW vs. ESW OT) Immunohistochemical iNOS staining scores in ESW group were higher than those of sham operated group (p 0.05, ESW vs. sham operated) iNOS staining scores in OT group were significantly lower than the ESW group (p 0.05, ESW OT vs. ESW)  OT ameliorates nitro oxidative stress and reduces the severity of pathological changes in the experimental ESW induced renal injury of rat model.
Environment exploration for object based visual saliency learning
Venue: 2016 IEEE International Conference on Robotics and Automation (ICRA)

Searching for objects in an indoor environment can be drastically improved if a task specific visual saliency is available. We describe a method to incrementally learn such an object based visual saliency directly on a robot, using an environment exploration mechanism. We first define saliency based on a geometrical criterion and use this definition to segment salient elements given an attentive but costly and restrictive observation of the environment. These elements are used to train a fast classifier that predicts salient objects given large scale visual features. In order to get a better and faster learning, we use an exploration strategy based on intrinsic motivation to drive our displacement in order to get relevant observations. Our approach has been tested on a robot in indoor environments as well as on publicly available RGB D images sequences. We demonstrate that the approach outperforms several state of the art methods in the case of indoor object detection and that the exploration strategy can drastically decrease the time required for learning saliency.
The relationship between relative deprivation and self rated health among Palestinian women in refugee camps in Lebanon
Venue: SSM population health

Relative deprivation (RD) has been advanced as a theory to explain the relationship between income inequality and health in high income countries. In this study, we tested the theory in a low income protracted refugee setting in a middle income country.  Using data from the 2010 Socioeconomic Survey of Palestine Refugees in Lebanon, we examined the relationship between RD and health among a representative sample of Palestinian refugee women (N=1047) Data were gathered utilizing a household questionnaire with information on socio demographics and an individual level questionnaire with information on the health of each respondent. We examined self rated health (SRH) as the main health measure but also checked the sensitivity of our results using self reported chronic conditions. We used two measures for absolute SES: total household monthly expenditures on non food goods and services and total household monthly expenditures on non health goods and services. With refugee camp as a reference group, we measured a household's RD as a household's rank of absolute SES within the reference group, multiplied by the distance between its absolute SES and the average absolute SES of all households ranked above it. We investigated the robustness of the RD SRH relationship using these two alternative measures of absolute SES.  Our findings show that, controlling for absolute SES and other possible confounders, women report significantly poorer health when they live in households with a higher score on our RD measure (because of either lower relative rank or lower relative SES compared to households better off in the reference group which we take to be the refugee camp) While RD is always significant as a determinant of SRH under a variety of specifications, absolute SES is not consistently significant. These findings persist when we use self reported chronic conditions as our measure of health instead of SRH, suggesting that the relationship between health and RD may be operating through a psychosocial mechanism.  Our findings underscore the importance of examining RD under conditions of poverty and in diverse socio cultural contexts. They also highlight that public health approaches should be concerned with reducing social inequalities in low income settings in addition to alleviating poverty.
