Published: June 2018

Abstract

BACKGROUND
An estimate of fetal fraction (FF) is needed for DNA-based screening for trisomy 21 and other aneuploidies, but there is no gold standard to validate FF measurement methods. We specify a gold standard and use it to validate a method of measuring FF (SeqFF) in singleton pregnancies.

METHODS
The gold standard was a formula derived from 2 elements: (a) an estimate of the percentage of DNA fragments in maternal plasma from chromosome 21 (%Ch21) in pregnancies without trisomy 21, 18, or 13 (PU) and (b) calculation of %Ch21 with increasing FF in trisomy 21 pregnancies (P21). The SeqFF method was evaluated by plotting regression lines of %Ch21 and SeqFF estimates of FF in 31 singleton male and 31 female trisomy 21 pregnancies and comparing the regressions with the reference line derived from the gold standard formula.

RESULTS
The gold standard formula was P21 = (1/2)PUFF + PU, with FF expressed as a proportion, or converting %Ch21 to multiples of the median (MoM), P21(MoM) = (1/2)FF + 1. Based on 3865 pregnancies, the PU was 1.2935%. The regression lines for trisomy 21 pregnancies with male and female fetuses were almost identical to the gold standard reference line (regression slopes in MoMs 0.52 and 0.50, respectively, compared with 0.50 for the gold standard reference line).

CONCLUSIONS
The proposed gold standard can be used to validate different methods of estimating FF in singleton pregnancies. SeqFF is an accurate method of estimating FF.

Published: June 2018

Infection of Onion yellow dwarf virus (OYDV) are reported causing problems in garlic production. Planting virus-free bulbs might help reduce viral disease incidence in the field. This research was aimed to develop method for eliminating OYDV from garlic bulbs using combination of electrotherapy (0, 5, 10, 15, and 20 mA each for 10 minutes) and thermotherapy (23, 28, 33, 38°C each for 4 weeks). Two garlic cultivars, i.e. Sangga Sembalun and Lumbu Hijau were used as seed bulbs for OYDV elimination tests. Virus infection was confirmed using transcription-polymerase chain reaction (RT-PCR). The result showed that thermotherapy at 33 °Cwas the best method to eliminate OYDV in garlic although the efficiency was not the same for all cultivars. The efficiency reached up to 60% for cv. Lumbu Hijau, whereas for cv. Sangga Sembalun only reached up to 40%. Electrotherapy alone or in combination with thermotherapy were not able to produce OYDV-free plantlets.
The Integrated Design of Power Dividerand Low-pass Filter
Authors: Wu Guoan , Dong Siyuan , Xu Qinfen 
Published: June 2018

Abstract
A compact filtering Wilkinson power divider with harmonic suppression based on lumped components is presented in this paper. The new divider uses two 5th-order elliptic-function low-pass filters to replace the quarter wavelength microstrip lines of the conventional Wilkinson power divider. The structure combines the power divider and the filter into a complete device. By integrating elliptic low-pass filters with the power divider, the proposed structure can suppress harmonics due to the filter’s band-notched characteristic. The power divider demonstrates a measured suppression of 37.1 dB for the second harmonic, 36.6 dB for the third harmonic, 38.6 dB for the fourth harmonic respectively. The harmonic suppression is higher than 20 dB from 2.75 to 7.035 GHz. Furthermore, lumped components are utilized to achieve improvement on size reduction. Compared with the conventional divider, the proposed structure effectively reduces the size by 77 %. The insertion loss is 3.2 dB at the center frequency (1.45GHz).

Published: June 2018

Abstract
Photovoltaic panel prices reduced last years. However, module cost per kWh is still expensive when compared with other energy sources. This paper discusses an economic analysis of photovoltaic arrays modified by alternative structures to increase their output power. These structures include increased incident irradiance by solar trackers and/or sun irradiance concentration enhanced by reduction of power losses caused by higher temperatures. Although, modules increased efficiency may demand for more expensive systems. Thus, study cases are presented considering each alternative structure used for photovoltaic power generation increase.

AbstractA simple graphG= (V,E) admits anH-covering, if every edge inE(G) belongs to a subgraph ofGisomorphic toH. A graphGadmitting anH-covering is called an (a,d)-H-antimagic if there exists a bijective functionf:V(G) ∪E(G) → {1, 2, …, |V(G)| + |E(G)|} such that for all subgraphsH′ isomorphic toHthe sums ∑v∈V(H′)f(v) + ∑e∈E(H′)f(e) form an arithmetic sequence {a,a+d, …,a+ (t− 1)d}, wherea> 0 andd≥ 0 are integers andtis the number of all subgraphs ofGisomorphic toH. Moreover, if the vertices are labeled with numbers 1, 2, …, |V(G)| the graph is called super. In this paper we deal with super cycle-antimagicness of subdivided graphs. We also prove that the subdivided wheel admits an (a,d)-cycle-antimagic labeling for somed.
Likegyldighetens tvetydighet: Overdosedødsfall etter rusmiddelbehandling

Published: June 2018

Ambiguous indifference – fatal overdoses among marginalized drug users after discharge from inpatient treatment Background In the European context, Norway is one of the countries with the highest overdose-related mortality rate. Research proves that the risk of overdose mortality among marginalized drug users is particularly high during the first weeks after discharge from inpatient treatment. Aim It is therefore interesting to investigate whether there might be a connection between marginalization and treatment culture to understand fatale overdoses after discharge from inpatient treatment. Design & Methods The case study is based on a previous field study connected to the death register. The study focuses on a single individual, Sam, and his treatment process. Data is analyzed in the light of a cultural analytical perspective. Results The results shows how the treatment system can be a social arena for institutional exclusion and marginalization that aggravate the person's self-esteem and life situation. One central aspect of the process of treatment was that it generated indifference. Sam's treatment motivation developed into treatment indifference. In the last part of the article, the author discusses indifference as a risk aspect of overdose mortality after discharged from treatment. It is not possible to conclude if Sam's overdose death was an accident or suicide. However, in the light of action theory the case shows that indifference can be a central aspect of both an unintentional and intentional overdose. Sam's death can be understood in the light of the concept ambiguous indifference. Conclusion The case shows that there may be a relationship between marginality, treatment culture and overdose mortality. Cultural and structural aspects of the treatment system put Sam in an empty and risky situation that probably contributed to his death. In a comparison of risk situations in this case-history with recent research on treatment system, we can see several worrisome resemblances considering overdose mortality after discharge from inpatient treatment.

Toohey, JC, Townsend, JR, Johnson, SB, Toy, AM, Vantrease, WC, Bender, D, Crimi, CC, Stowers, KL, Ruiz, MD, VanDusseldorp, TA, Feito, Y, and Mangine, GT. Effects of probiotic (Bacillus subtilis) supplementation during offseason resistance training in female Division I athletes. J Strength Cond Res 34(11): 3173–3181, 2020–We examined the effects of probiotic (Bacillus subtilis) supplementation during offseason training in collegiate athletes. Twenty-three Division I female athletes (19.6 ± 1.0 years, 67.5 ± 7.4 kg, and 170.6 ± 6.8 cm) participated in this study and were randomized into either a probiotic (n = 11; DE111) or placebo (n = 12; PL) group while counterbalancing groups for sport. Athletes completed a 10-week resistance training program during the offseason, which consisted of 3–4 workouts per week of upper- and lower-body exercises and sport-specific training. Athletes consumed DE111 (DE111; 5 billion CFU/day) or PL supplement daily for the entire 10-week program. Before and after training, all athletes underwent 1 repetition maximum (1RM) strength testing (squat, deadlift, and bench press), performance testing (vertical jump and pro-agility), and isometric midthigh pull testing. Body composition (body fat [BF]%) was completed using BODPOD and bioelectrical impedance analysis, as well as muscle thickness (MT) measurement of the rectus femoris (RF) and vastus lateralis using ultrasonography. Separate repeated-measures analyses of variance were used to analyze all data. Significant (p ≤ 0.05) main effects for time were observed for improved squat 1RM, deadlift 1RM, bench press 1RM, vertical jump, RF MT, and BF%. Of these, a significant group × time interaction was noted for BF% (p = 0.015), where greater reductions were observed in DE111 (−2.05 ± 1.38%) compared with PL (−0.2 ± 1.6%). No other group differences were observed. These data suggest that probiotic consumption in conjunction with post-workout nutrition had no effect on physical performance but may improve body composition in female Division I soccer and volleyball players after offseason training.

Published: June 2018

La thématique de la colonisation grecque aux époques archaïque et classique relève d’un ensemble de débats historiographiques récents et met en lumière les partis pris anciens et modernes dans l’étude des mobilités individuelles et collectives des anciens Grecs. L’Antiquité se fait ainsi très actuelle. The issue of Greek colonization in Archaic and Classic periods stands from a set of recent historiographical debate and it underlines ancient and modern standpoints in the study of Greek individual and collective mobility. Antiquity becomes thus very present.

L’Italie du Sud est probablement la région la mieux connue du monde grec antique. Quelques sources écrites mais surtout des études archéologiques menées depuis longtemps ont permis le développement des recherches sur plusieurs aspects au cœur de la thématique de la colonisation grecque. Ce travail se concentre sur trois aspects essentiels : l’appropriation de l’espace colonial, l’interaction avec les populations indigènes et l’urbanisation des nouvelles installations. The South Italy is probably the best known region of the ancient Greek world. Some written sources but especially archaeological work undertaken for a long time allowed the development of research on several aspects at the heart of the issues of Greek colonization. This paper concentrates on three essential aspects: the appropriation of colonial space, the interaction with the native populations, and the urbanization of new establishments.
Os Gregos no Adriático
Authors: Castiglioni Maria Paola 
Published: June 2018

Situado no cruzamento entre as penínsulas Balcânica e Italiana, e conectando os espaços mediterrânicos das regiões da Europa central e setentrional, o mar Adriático experimentou uma importante presença grega a partir de pelo menos meados do século IX a.C. Atraídos pelas oportunidades comerciais às quais os litorais desse mar davam acesso, os gregos, no entanto, raramente se instalaram de forma permanente em estrutura de apoikia. Através de uma apresentação sintética, esta contribuição visa a pôr em evidência como a "mobilidade" grega nesse mar está inserida nos contextos históricos mais vastos e complexos (a "tirania" de Periandro, os projetos hegemônicos de Dionísio de Siracusa) e destacar o impacto das implantações coloniais ou empóricas gregas nas populações locais.

Objectives
The objective of this study is to investigate the effect of comorbid conditions [Charlson comorbidity index (CCI)] on stent restenosis who underwent coronary angioplasty earlier.

Methods
Patients were divided into two groups; patients with critical restenosis [recurrent diameter stenosis >50% at the stent segment or its edges (5-mm segments adjacent to the stent) (Group 1; n = 53, mean age: 63.8 ± 9.9 years)] and patients with no critical restenosis [<50% obstruction (Group 2; n = 94, mean age: 62.1 ± 9.1 years)]. The CCI and modified CCI were used for the presence of comorbid conditions. The Gensini scoring system was used to assess the extent of coronary artery disease (CAD).

Results
Group 1 had a significantly greater CCI and modified CCI score compared to Group 2 (7.1 ± 3.7 vs. 5.6 ± 1.6, p = 0.006; 6.9 ± 3.6 vs. 4.5 ± 1.5, p = 0.008, respectively). There was a weak correlation, albeit significant, between the modified CCI score and restenosis percentage (r = 0.29, p < 0.001; r = 0.25, p = 0.003, respectively).

Conclusions
In conclusion, the CCI score is greater among patients with stent restenosis than those without. CCI score is higher among patients with a more diffuse CAD than with a milder disease extent.

Does anti-reflux surgery control Barrett’s oesophagus progression?
Authors: Alghazzawi Ali J. , Khabaza Ali A. , Al-Hijaji Mohammed H. 
Published: June 2018

Controversy exists as to whether or not anti-reflux surgery can prevent the potential long-term complications of Barrett's oesophagus, in particular, dysplastic changes. Hence, literature was reviewed to find out effects of anti-reflux surgery on patients with Barrett's oesophagus. Data has been analysed using different electronic database including Ovid Medline, Scopus, Google Scholar and PubMed. Anti-reflux surgery is considered an effective option for rapid and long-term control of reflux symptoms. Most patients who were included in the studies had a satisfactory control of their symptoms after surgery. Successful procedures effectively abolished gastric reflux in the majority of patients. On the other hand, there were different patterns of Barrett's oesophagus segment progression after surgery regardless of the procedure's success. Many patients developed de novo Barrett's oesophagus, at the same time the intestinal metaplasia regressed in other patients, but the Barrett segment has remained unchanged in the majority of patients. Similarly, the pattern of dysplasia progression was different among patients. Surgery was effective in producing dysplasia regression in many patients, but it failed to prevent progression of columnar intestinal metaplasia into dysplasia in other patients. In conclusion the potential long-term complications of Barrett's oesophagus can develop after anti-reflux surgery. Therefore, long life follow- up, after surgery, is mandatory.
