Published: September 2017

Periodontal disease is very common during pregnancy. Although it has been linked to adverse pregnancy outcomes, systematic reviews have reached discrepant conclusions on these links. Therefore, we conducted a systematic overview of systematic reviews studying the association between periodontal disease and adverse pregnancy outcomes. We searched 6 online databases up to November 2016 and hand-searched references and citations of eligible papers. Systematic reviews of studies comparing pregnancy outcomes among women with and without periodontal disease were eligible for inclusion. Primary outcomes were maternal mortality, preterm birth, and perinatal mortality. Two reviewers extracted data and assessed risk of bias of individual systematic reviews. Findings are described in tabular and narrative form. Twenty-three systematic reviews (including between 3 and 45 studies) were included. None reported the association between periodontal disease and maternal or perinatal mortality. Systematic reviews with the lowest risk of bias consistently demonstrated positive associations between periodontal disease and preterm birth (relative risk, 1.6; 95% confidence interval, 1.3 to 2.0; 17 studies, 6,741 participants), low birth weight (LBW; relative risk, 1.7; 95% CI, 1.3 to 2.1; 10 studies, 5,693 participants), preeclampsia (odds ratio, 2.2; 95% CI, 1.4 to 3.4; 15 studies, 5,111 participants), and preterm LBW (relative risk 3.4; 95% CI, 1.3 to 8.8; 4 studies, 2,263 participants). Based on these figures, estimated population-attributable fractions for periodontal disease were 5% to 38% for preterm birth, 6% to 41% for LBW, and 10% to 55% for preeclampsia. In terms of limitations, as several primary studies did not adjust for confounding, meta-analyses may have overestimated the strength of the associations under study. Due to substantial overlap in included primary studies, we could not aggregate results across reviews. Consistent evidence from systematic reviews with low risk of bias indicates that pregnant women with periodontal disease are at increased risk of developing preeclampsia and delivering a preterm and/or LBW baby (PROSPERO: CRD42015030132). Knowledge Transfer Statement: This study highlights that periodontal disease is an important risk factor for several common adverse pregnancy outcomes. Clinicians should be aware of this link to guide risk selection. Research is needed to develop novel preventive and treatment strategies.

Abstract
Ensifer meliloti
Mlalz-1 (INSDC = ATZD00000000) is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from an effective nitrogen-fixing nodule of
Medicago laciniata
(L.) Miller from a soil sample collected near the town of Guatiza on the island of Lanzarote, the Canary Islands, Spain. This strain nodulates and forms an effective symbiosis with the highly specific host M. laciniata. This rhizobial genome was sequenced as part of the DOE Joint Genome Institute 2010 Genomic Encyclopedia for Bacteria and Archaea-Root Nodule Bacteria (GEBA-RNB) sequencing project. Here the features of
E. meliloti
Mlalz-1 are described, together with high-quality permanent draft genome sequence information and annotation. The 6,664,116 bp high-quality draft genome is arranged in 99 scaffolds of 100 contigs, containing 6314 protein-coding genes and 74 RNA-only encoding genes. Strain Mlalz-1 is closely related to
Ensifer meliloti
IAM 12611T,
Ensifer medicae
A 321T and
Ensifer numidicus
ORS 1407T, based on 16S rRNA gene sequences. gANI values of ≥98.1% support the classification of strain Mlalz-1 as
E. meliloti
. Nodulation of M. laciniata requires a specific nodC allele, and the nodC gene of strain Mlalz-1 shares ≥98% sequence identity with nodC of M. laciniata-nodulating
Ensifer
strains, but ≤93% with nodC of
Ensifer
strains that nodulate other
Medicago
species. Strain Mlalz-1 is unique among sequenced
E. meliloti
strains in possessing genes encoding components of a T2SS and in having two versions of the adaptive acid tolerance response lpiA-acvB operon. In
E. medicae
strain WSM419, lpiA is essential for enhancing survival in lethal acid conditions. The second copy of the lpiA-acvB operon of strain Mlalz-1 has highest sequence identity (> 96%) with that of
E. medicae
strains, which suggests genetic recombination between strain Mlalz-1 and
E. medicae
and the horizontal gene transfer of lpiA-acvB.
Empirical Investigation of an Equity Pairs Trading Strategy
Authors: Chen Huafeng (Jason) , Chen Shaojun (Jenny) , Chen Zhuo , Li Feng 
Published: September 2017

We show that an equity pairs trading strategy generates large and significant abnormal returns. We find that two components of the trading signal (i.e., short-term reversal and pairs momentum) have different dynamic and cross-sectional properties. The pairs momentum is largely explained by the one-month version of the industry momentum. Therefore, the pairs trading profits are largely explained by the short-term reversal and a version of the industry momentum.

Narrative Leaps to Universal Appeal in McKay’s Banjo and Faulkner’s AFable
Authors: Dye Dotty , Watson Jay 
Published: September 2017

This chapter explores connections between Claude McKay and William Faulkner by considering the way each writer negotiates aesthetics and politics in his fiction. Focusing on fictional texts set in France, it engages with critical conversations about the extent to which travel, negotiation of identity and the idea of “home,” may have impacted each writer’s work. The textual and aesthetic interaction between the particular and the universal in each writer’s work informs, in intersecting ways, their approaches to race, gender, class and nationalism and this chapter explores this vast range of intersections by focusing on the mapping of race and home that operate within the texts.
Survival and Evaluation of Clinical and Laboratory Variables as Prognostic Indicators in Horses Hospitilized with Acute Diarrhea: 342 Cases (1995-2015)
Authors: Kovač Milomir , Huskamp Bernhard , Scheidemann Wolfgang , Toth Joseph , Tambur Zoran 
Published: September 2017

AbstractA retrospective study was performed on 342 horses with acute diarrhea (equine colitis). Clinical and laboratory data were obtained upon arrival at the equine hospital. The main focus of this study was to find the difference between the clinical and laboratory variables of surviving and deceased acute colitis horses before the beginning of medical treatment, with the aim to provide a better guideline for determining the prognosis of survival. According to this retrospective study the lethality rate of acute equine colitis was 41.93 %. The time interval from the onset of acute diarrhea to the horse being taken to the clinic was significantly longer in the case of horses which had not survived. The heart rate, hematocrit, blood pH, blood hydrogen carbonate concentration, base excess and HCT/TPP ratio were shown to be significantly related to the survival of horses with colitis. Thus, the hematocrit, appeared to be the most relevant predictor of the outcome of acute equine colitis. Body temperature, respiration rate, total plasma protein and white blood cell count, did not show any prognostic significance.

Published: September 2017

Abstract
During 2015/2016, fecal and intestinal samples from live diseased and/or dead pigs with suspected PEDV and/or TGEV and signs of rotavirus infection were collected from in total seven different farrow-to-finish swine farms located in Northern Serbia region (Vojvodina Province). A total of 14 samples (2 pools per farm) of small intestine with fecal content were submitted to laboratory molecular investigation (multiplex RTPCR). On these farms the clinical signs included the occurrence of diarrhea in suckling and weaned piglets, with weak or no response to the applied antimicrobial therapy. The epidemic of severe diarrhea affecting pigs of all ages on one farrow-to finish swine farm was detected in January 2016. Watery diarrhea in all swine categories was associated with vomiting and a reduction in feed consumption. Diarrheic, gaunt and dehydrated piglets, covered with feces were found in 90% litters. The disease affected most severely the suckling piglets, and the mortality in newborn piglets was up to 35%. In the weaned piglets and fatteners the mortality was up to 2.5% and 1.2%, respectively. The PEDV RNA was detected in pooled feces and samples of small intestines derived from diseased and dead suckling piglets from only one investigated farm. The PEDV positive samples showed to be negative for rotavirus group A and TGEV. The transport vehicles were identified as the main possible route of PEDV introduction. This is the first report demonstrating the presence of PEDV in Serbia.

Published: September 2017

Abstract
The gene IGF1 has been shown to have a significant influence on the size of individuals, including animals of the Canidae family. In this study we determined SNP mutations of the IGF1 gene in dogs, raccoon dogs and farmed and free-living red foxes from Poland and Canada. No SNP mutations were noted in dogs or raccoon dogs, but a total of 14 single nucleotide polymorphisms were identified in foxes, including 12 substitutions, as well as one new mutation missense variant (exon 6) in wild Polish foxes and one synonymous mutation variant in wild foxes from Canada. We identified specific SNP profiles characteristic only for farmed foxes and only for wild foxes, as well as specific SNP profiles or wild foxes from North America (Canada) and from Europe (Poland).

Published: September 2017

Abstract
Infectious arthritides in goats is mainly caused by mycoplasmas and Caprine Arthritis- Encephalitis virus (CAEV). Streptococcus equi subspecies zooepidemicus (S. zooepidemicus) is a member of Lancefield group C beta-hemolytic streptococcus that commonly colonizes the mucous membranes of healthy equids which is also capable to induce different pathological conditions in many animal species. In this paper we described a case of polyarthritis in four Alpine goat-kids caused by S. zooepidemicus. Goat-kids originated from a farm where sheep, llamas, shepherd dogs, cows and horses were kept with goats. During the external examination of carcasses, crusts and discrete hyperemia were seen on the earlobes beneath the ear tag, as well as swollen joints. Necropsy findings included severe fibrinous polyarthritis in all four examined kids. Shoulder, knee and hip joints were affected. From all affected joints S. zooepidemicus was isolated. Neither Mycoplasma spp. nor CAEV genome were detected from the affected joints. Most likely the goatkids were infected with S. zooepidemicus through the lesions on earlobes which were made after the tagging. As a possible source of bacteria, we recognized the horses and dogs. Due to the lack of any signs of illness in other animal species on the farm, as well as negative pathomorphological findings in other organs, we assumed that the isolated strain is highly adapted to goat-kids. Our report is the first described case of polyarthritis in goat-kids caused by S. zooepidemicus.
Elbow Joint Luxation in a Ten Months Old Arabian Colt – A Case Report

Published: September 2017

AbstractElbow joint luxation without concomitant fracture is uncommon in horses. This paper reports on a case of elbow joint luxation in a ten months old Arabian colt. The horse was presented with a history of an acute onset of non-weight bearing right front limb lameness with edema of the affected region lasting for six days. Radiographic imaging indicated luxation of the elbow joint; however, useful information about the severity of soft tissue involvement was obtained using ultrasonography since bilateral collateral ligaments were completely disrupted. The owner opted for euthanasia and necropsy confirmed the diagnosis. Although very rare, elbow joint luxation should be considered in cases of acute forelimb lameness in young horses.
Feedback design of differential equations of reconstruction for second–order distributed parameter systems
Authors: Maksimov Vyacheslav I. , Mordukhovich Boris S. 
Published: September 2017

AbstractThe paper aims at studying a class of second-order partial differential equations subject to uncertainty involving unknown inputs for which no probabilistic information is available. Developing an approach of feedback control with a model, we derive an efficient reconstruction procedure and thereby design differential equations of reconstruction. A characteristic feature of the obtained equations is that their inputs formed by the feedback control principle constructively approximate unknown inputs of the given second-order distributed parameter system.
On the Farey sequence and its augmentation for applications to image analysis
Authors: Pratihar Sanjoy , Bhowmick Partha 
Published: September 2017

AbstractWe introduce a novel concept of theaugmented Farey table(AFT). Its purpose is to store the ranks of fractions of aFarey sequencein an efficient manner so as to return therankof any query fraction in constant time. As a result, computations on the digital plane can be crafted down to simple integer operations; for example, the tasks like determining the extent of collinearity of integer points or of parallelism of straight lines—often required to solve many image-analytic problems—can be made fast and efficient through an appropriate AFT-based tool. We derive certain interesting characterizations of an AFT for its efficient generation. We also show how, for a fraction not present in a Farey sequence, the rank of thenearest fractionin that sequence can efficiently be obtained by theregula falsimethod from the AFT concerned. To assert its merit, we show its use in two applications—one in polygonal approximation of digital curves and the other in skew correction of engineering drawings in document images. Experimental results indicate the potential of the AFT in such image-analytic applications.
Assessment of Post-Occlusive Reactive Hyperaemia in the Evaluation of Endothelial Function in Patients with Lower Extremity Artery Disease
Authors: Carasca Cosmin , Magdas Annamaria , Tilea Ioan , Incze Alexandru 
Published: September 2017

Abstract

Background: The aim was to assess endothelial function with photoplethysmography (PPG), by post-occlusive reactive hyperaemia (PORH) combined with alprostadil challenge test in patients with peripheral artery disease (PAD).

Methods: Forty-nine PAD patients stage II-III Fontaine (39 male, 10 female, mean age 68.45±5.86 years) and a control group of 49 healthy individuals (24 male, 25 female; mean age 25.1±3.8 for a young subgroup; 71.0±0.16 years for an elderly subgroup) were included. Ankle-brachial index (ABI) was assessed at baseline, peripheral perfusion (PP) and PORH were assessed at baseline and after the 30 minutes administration of parenteral alprostadil.

Results: After 3 minutes of arterial occlusion, peripheral perfusion increased from 0.69±0.94 mV/V to 2.27±2.42 mV/V (p<0.0001). After alprostadil challenge, peripheral perfusion increased from 0.84±1.24 mV/V to 4.52±3.52 mV/V (p<0.0001). In controls PP was 2.4±1.7 mV/V versus 3.8±1.5 mV/V, p<0.0001.

Conclusion: In patients with PAD, an increase in PORH after alprostadil challenge due to the release of nitric oxide (NO), provides information on the endothelial function and could reflect the presence of collaterals. In the healthy control group, the increase in PORH could reflect the integrity of main arterial branch. In PAD patients with an increase in PORH, conservative therapy should be preferred over surgical revascularisation.
Heterozygous Deletion in Exons 4-5 of SHOX Gene in a Patient Diagnosed as Idiopathic Short Stature
Authors: David Anna , Kun Imre Zoltán , Nyírő Gábor , Szántó Zsuzsánna , Patócs Attila 
Published: September 2017

Abstract

Introduction: Isolated Short Stature Homeobox (SHOX) gene haploinsufficiency can be found in 2-15% of individuals diagnosed with idiopathic short stature determining different skeletal phenotypes.

Case presentation: We present the history of an 11-year-old female patient diagnosed with idiopathic short stature. Clinically, she was moderately disproportionate, with cubitus valgus and palatum ogivale. Her breast development was in Tanner stage 1 at the time of diagnosis. The endocrine diagnostic tests did not reveal any abnormalities except a slightly elevated thyroid stimulating hormone. We have also assessed the bone radiological findings. Multiplex Ligation-dependent Probe Amplification technique used for the identification of SHOX gene haploinsufficiency showed a heterozygous deletion spanning exons 4-5 of SHOX gene.

Conclusions: This case is determined by deletions in exons 4-5 of SHOX gene and indicates the necessity of screening for SHOX deletions in patients diagnosed with idiopathic short stature, especially in children having increased sitting height-to-height ratio or decreased extremities-to-trunk ratio.

Abstract
This study examined the economics and determinants of pig production in Ogun State, Nigeria using Obafemi Owode and Odeda Local Government in Ogun State, Nigeria where the enterprise is most prominent. The data used for the study were obtained from 60 respondents as there are very few farmers into this business in the state compared to other livestock production. Pig farmers were sampled through snowball sampling technique. The data collected were analyzed with descriptive statistics, budgetary, and Ordinary Least Square regression model. Results from the study revealed that the mean age of the respondents was 36.6 years and they were predominantly (81.7 %) male. Most (68.3 %) of the farmers had no access to credit with half of them married. On the cost and returns, returns on investment were positively associated with herd size, breed, and type of management system in the study area. When controlling for years of production experience and herd size, with every 1 naira increase in variable costs, the return on investment decreased by ₦0.879 ≈ $0.0044 (P < 0.01). Similarly, when controlling for herd size and variable costs, with every 1 year of increase in production experience, the return on investment increased by ₦1.85 ≈ $0.0092 (P < 0.01). When controlling for number of years of production experience and variable costs, with every 1 naira increase in cost of stock, the return on investment increased by ₦1,652.74 ≈ $8.22 (P < 0.05). Lastly, when controlling for number of years of production experience and variable costs, every increase of herd size of 1 pig resulted in a return on investment of ₦1, 502.14 ≈ $7.47 (P < 0.01). Level of pig production experience, herd size, variable costs items, cost of stock, and access to credit had significant influence on the production of pig in the study area. The study therefore recommends subsidization of input costs, the need for extension officers or experts to educate less experienced farmers on pig production and effective extension services targeted at raising technical knowledge of pig farmers towards effective productivity and profitability.
Perceived Effects of Sand Dredging on Livelihood Diversification of Artisanal Fisher Folks in Lagos State, Nigeria

Published: September 2017

AbstractThe study examined perceived effects of sand dredging activities on livelihood diversification of artisanal fisher folks in Lagos State, Nigeria. Multi-stage sampling procedure was used to select respondents for the study. Purposively, Eti-Osa, Ibeju-Lekki, Epe and Ikorodu local Government Areas (LGAs) were selected for intensive dredging activities. Registered artisanal fishermen in these LGAs were 310, 350, 380 and 320, respectively. Twenty percent of the population in each LGAs were selected using simple random sampling technique to arrive at 272 respondents interviewed for the study. An interview schedule guide was used to elicit information on respondents’ socio-economic characteristics, knowledge, livelihood diversification and perception of the sand dredging effect on fishing activities. Data were analyzed using descriptive statistics, Pearson Product Moment Correlation and independent sample t-test. The mean age of fisher folks was 37 ± 8 years, 92.1 % of them were males, 81.4 % were married and had households’ size ranging from 1 to 16 persons. Over 50 % of the respondents had no formal education. Monthly income of fisher folks in the study area ranged from ₦5, 000 to ₦60, 000 with a mean income of ₦22, 892 ± 13,564 and majority (92.9 %)were members of a social group. Respondents diversified most into off-farm activities such as commercial bike riding, security and technician services. Slightly above half (55.7 %) perceived sand dredging as having a negative effect on fishing activities. Results on inferential statistic revealed that a significant relationship existed between knowledge of sand dredging effect on fishing activities (r = 0.35), monthly income (r = −0.181) and social group (χ2= 2.886) and perceived effects of sand dredging on fishing activities. Deliberate policy drive to mitigate sand dredging practices is required to forestall the negative effect on livelihood diversification of the artisanal fisher folks. Consequently, the artisanal fishery contribution to total Gross Domestic Product (GDP), employment generation and total domestic fish production will be enhanced.
Old Genres in New Attire: Zsolna Ugron’s Novels
Authors: Prohászka-Rád Boróka , Salamon Boróka 
Published: September 2017

Abstract
In the present study we propose a look at Zsolna Ugron’s works from a generic perspective in order to analyze what conventions of genres such as the romance, the epistolary novel and the historical romance the author has revived and what are the elements that she has added or changed in order to make them appealing to the public and yield to critical analysis. We also attempt an investigation of the formation of female subjectivity as illustrated by these fundamentally feminine novels, given that all four of them operate with female protagonists, women in the process of shaping their destinies, often at crossroads where - despite all the external factors that seem to determine their fate from history to social conventions and men around them - ultimately they make their own personal choices and position themselves as responsible, active and creative subjects.
