Amaç: Vitrifiye embriyo transfer (VET) sikluslarında progesteron (P) desteği öncesi östradiyol (Ö) kullanım süresinin canlı doğum oranını (CDO) etkileyip etkilemediğini değerlendirmek Gereçler ve Yöntem: Bu retrospektif kohort çalışma, Ekim 2015 ve Ekim 2017 arasında Amerikan Hastanesi Üremeye Yardımcı Teknikler Ünitesi’nde GnRH agonist uygulamasız artifisyel endometriyum hazırlığı ile tek blastokist transferi yapılan tüm hastaları kapsamaktadır. Sadece G1 ve G2 iyi kalitede blastokistler dondurulmuştur. &gt;43 yaş olanlar, tedavi siklus kayıtlarında eksik verileri olan veya takipten çıkan hastalar çalışma dışı bırakılmıştır. Tüm hastalara âdetin 2. günü 6 mg sabit dozdan oral Ö tedavisi başlanmıştır. Östradiyol kullanım süresi embriyo transfer (ET) günü planlamasına göre 8 ile 14 gün arası değişmektedir. Toplamda 241 hastanın VET siklusu Ö kullanım sürelerine göre (Grup 1: &lt;12 gün, n=105; Grup 2: ³12 gün, n=136) analiz edilmiştir. Çalışmanın primer sonuç değişkeni CDO’ dır. Bulgular: Toplam 241 VET siklusundaki P kullanımı öncesi E kullanım süresi: 8 gün (%3), 9 gün (%8), 10 gün (%16), 11 gün (%16.5), 12 gün (%22.5), 13 gün (%20.5), 14 gün (%13.5) şeklinde dağılım göstermektedir. Östradiyol takviyesinin 12 günün altında kullanımının 12 gün üzerinde kullanımına kıyasla CDO üzerine anlamlı etkisi yoktur (OR=1.25; %95 CI [0.75-2.1], p=0.38). Klinik gebelik, erken ve fetal kayıp oranları da gruplar arasında benzerdir. Ortalama endometrial kalınlık gruplar arasında benzerdir (9.5mm). Östradiyol takviyesinin reprodüktif sonuçlarla ilişkisi her gün için ayrı ayrı değerlendirildiğinde de anlamlı bir fark saptanmamıştır Sonuç: Vitrifiye embriyo transfer sikluslarında genel kabul görenden daha kısa östradiyol kullanımı canlı doğum oranlarını etkilememekte, abort riskini artırmamaktadır. Bu durum test edilmemiş ancak kuvvetle kabül görmüş bu protokolü sorgulanır kılmaktadır

Shia Armed Groups and the Future of Iraq
Authors: Rached Kardo , Bali Ahmed Omar 
Published: November 2019

The rising and acceleration of the Shia armed group in Iraq, Syria, Yemen, and Lebanon require a deep understanding of the root of the multi-dimensional conflicts in the Middle East. An appropriate and sufficient approach to the research about these militias will be from an internal conflict rather than an external conflict. The legitimization for the existence of the majority of these militias if not all of them is to fight and struggle against an entity which is the Sunni sect, in this case, that will assimilate them not integrate them peacefully.

Published: November 2019

Background: Epidemiological data on the prevalence of ulcerative colitis (UC) and Crohn's disease (CD) in Russia are limited.Aim: To evaluate the proportions and clinical particulars of inflammatory bowel diseases (IBD) in patients living in the Chelyabinsk Region.Materials and methods: We performed a retrospective analysis of a database of IBD patients residing in the city of Chelyabinsk and the Chelyabinsk Region for the period from 2016 to 2019.Results: The database includes 693 patients, among them 582 (84%) with UC and 111 (16%) with CD. With UC, the ratio of women (313 people) to men (269 people) was 1.16:1, while with CD (70 women and 41 men) it was 1.7:1. The mean age of UC patients was 46.3±15.8 years, of those with CD 45.79±18.1 years. 631 (90%) IBD patients live in the city, the number of rural residents was significantly lower (62, or 10%) (p<0.001). Disability caused by the underlying disease was 11.9% of the patients with UC and 23.4% of the CD patients. The mean age of the disease manifestation was 39.3±15.03 years (UC) and 38.7±17.8 years (CD). The time to diagnosis of UC was 6.1±4.0 months and of CD 7.6±5.5 months (р=0.045). Proctitis was diagnosed in 56 patients with UC (9.6%), left-sided colitis in 301 (51.7%), and total colitis in 225 (38.7%). Terminal ileitis was detected in 34 (30.6%) CD patients, colitis in 25 (22.6%), mixed colon and small intestine involvement in 52 (46.8%), and combined involvement of the upper gastrointestinal tract in 3 (3%) patients. The course of UC was acute in 25 (4.3%) patients, chronic continuous in 52 (8.9%), and chronic recurrent in 505 (86.8%). Extraintestinal manifestations were observed in 135 (19.5%) patients with IBD. Genetically engineered biological therapy was prescribed to 77 (11%) patients.Conclusion: The epidemiological trends for IBD, which we have identified through the analysis of the database for the city of Chelyabinsk and the Chelyabinsk Region, are consistent with the results of studies in other regions of the Russian Federation: IBD manifests in the middle age, the time to diagnosis of CD is longer for that of UC. Total colitis is most frequent in UC, whereas in CD mixed colon and small intestine involvement is most prevalent. Ninety percent (90%) of IBD patients at the time of the database entry had a mild or moderate exacerbation of their disease.

Subsea Water-Treatment System Installed in Pilot Test at Ekofisk
Authors: Feder Judy 
Published: November 2019

This article, written by JPT Technology Editor Judy Feder, contains highlights of paper OTC 29552, “Subsea Water Treatment Pilot Testing at the Ekofisk Field in the North Sea,” by Eirik Dirdal, National Oilwell Varco, prepared for the 2019 Offshore Technology Conference, 6–9 May, Houston. The paper has not been peer reviewed. Copyright 2019 Offshore Technology Conference. Reproduced by permission.
A subsea water-treatment system designed to leverage space availability, steady temperatures, lower bacteria levels, and other natural benefits of the seabed environment was successfully installed during pilot testing at the Ekofisk field offshore Norway. After several phases of testing, a full-scale water-treatment module was built and installed, and at the time the complete paper was written, the pilot had moved into the long-term testing phase to determine the system’s viability under North Sea field conditions. According to the author, if the system succeeds, it could drive a major change in injection-water management offshore.
Introduction
The Ekofisk field was originally developed with pressure depletion as the primary drive mechanism. After several decades of production, significant resources are still in place. Limited gas injection and comprehensive water injection have contributed to a substantial increase in oil recovery. Large-scale water injection began in 1987, and has been extended in several phases. Water displacement of the oil has been successful, and the recoverable resources have been adjusted correspondingly upward from the original 17% to an estimated final recovery factor of greater than 50%.
An important factor in the success of a waterflood project is the quality of the injected water. In worst-case scenarios, poor water quality can cause plugging and reservoir souring. Water quality is greatly affected by contaminants such as suspended solids, corrosion products, scale, and bacteria. Controlling corrosion and disinfection of biomass are two major challenges associated with waterflood. The two challenges are linked because oxidants are required to reduce bacterial activities that could lead to microbial-induced corrosion, but the oxidants also promote corrosion.
Joint-Industry Project (JIP) Results
Development of the injection-water treatment system described in the paper began in 2004. Det Norske Veritas’ recommended practice for qualification of new technology has been used throughout the development process. On the basis of successful experimental testing that demonstrated proof of the concept, a JIP supported by several oil and gas majors was launched in 2009. A prototype was built and tested in 65 m of water depth in Oslofjorden, a sheltered environment in a fjord, to verify the water-treatment module’s performance and reliability through seasonal variations in real offshore conditions. Results demonstrated that the treatment method, which combined various electrolysis approaches, provided very good water quality, in many aspects superior to that achieved by topside seawater-treatment plants.
Comparison of intraocular pressure measured by ocular response analyzer and Goldmann applanation tonometer after corneal refractive surgery: a systematic review and meta-analysis
Authors: Zhang Hui , Sun Zhengtao , Li Lin , Sun Ran , Zhang Haixia 
Published: November 2019

Abstract
Background: Accurate measurement of intraocular pressure (IOP) after corneal refractive surgery is of great significance to clinic, and comparisons among various IOP measuring instruments are not rare, but there is a lack of unified analysis. Although Goldmann Applanation Tonometer (GAT) is currently the internationally recognized gold standard for IOP measurement, its results are severely affected by central corneal thickness (CCT). Ocular Response Analyzer (ORA) takes certain biomechanical properties of cornea into account and is supposed to be less dependent of CCT. In this study, we conducted the meta-analysis to systematically assess the differences and similarities of IOP values measured by ORA and GAT in patients after corneal refractive surgery from the perspective of evidence-based medicine.
Methods: The authors searched electronic databases (MEDLINE, EMBASE, Web of science, Cochrane library and Chinese electronic databases of CNKI and Wanfang) from Jan. 2005 to Jan. 2019, studies describing IOP comparisons measured by GAT and ORA after corneal refractive surgery were included. Quality assessment, subgroup analysis, meta-regression analysis and publication bias analysis were applied in succession.
Results: Among the 273 literatures initially retrieved, 8 literatures (13 groups of data) with a total of 724 eyes were included in the meta-analysis, and all of which were English literatures. In the pooled analysis, the weighted mean difference (WMD) between IOPcc and IOPGAT was 2.67 mmHg (95% CI: 2.20~3.14 mmHg, p < 0.0001), the WMD between IOPg and IOPGAT was -0.27 mmHg (95% CI: -0.70~0.16 mmHg, p = 0.2174). In the subgroup analysis of postoperative IOPcc and IOPGAT, the heterogeneity among the data on surgical procedure was zero, while the heterogeneity of other subgroups was still more than 50%. The comparison of the mean difference of pre- and post-operative IOP (∆IOP) was: mean-∆IOPg > mean-∆IOPGAT > mean-∆IOPcc.
Conclusions: IOPcc, which is less dependent on CCT, may be more close to the true IOP after corneal refractive surgery compared with IOPg and IOPGAT, and the recovery of IOPcc after corneal surface refractive surgery may be more stable than that after lamellar refractive surgery.
Variation in plastid genomes in the gynodioecious species Silene vulgaris
Authors: Krüger Manuela , Abeyawardana Oushadee A.J. , Juricek Miloslav , Krüger Claudia , Storchova Helena 
Published: November 2019

Abstract
Background Gynodioecious species exist in two genders – male-sterile females and hermaphrodites. Male sterility in higher plants often results from mitonuclear interaction between the CMS (cytoplasmic male sterility) gene(s) encoded by mitochondrial genome and by nuclear-encoded restorer genes. Mitochondrial and nuclear-encoded transcriptomes in females and hermaphrodites are intensively studied, but little is known about gender-specific gene expression in plastids. We have compared plastid transcriptomes between females and hermaphrodites in two haplotypes of a gynodioecious species Silene vulgaris with known CMS candidate genes. Results We generated complete plastid genome sequences from five haplotypes S. vulgaris including the haplotypes KRA and KOV, for which complete mitochondrial genome sequences were already published. We constructed a phylogenetic tree based on plastid sequences of S. vulgaris. Whereas lowland S. vulgaris haplotypes including KRA and KOV clustered together, the accessions from high European mountains diverged early in the phylogram. S. vulgaris belongs among Silene species with slowly evolving plastid genomes, but we still detected 212 substitutions and 112 indels between two accessions of this species. We estimated elevated Ka/Ks in the ndhF gene, which may reflect the adaptation of S. vulgaris to high altitudes, or relaxed selection. We compared depth of coverage and editing rates between female and hermaphrodite plastid transcriptomes and found no significant differences between the two genders. We identified 51 unique C to U editing sites in the plastid genomes of S. vulgaris, 38 of them in protein coding regions, 2 in introns, and 11 in intergenic regions. The editing site in the psbZ gene was edited only in one of two plastid genomes under study. Conclusions We revealed no significant differences between the genders in plastid transcriptomes of two haplotypes of S. vulgaris. It suggests that gene expression of plastid genes is not affected by CMS in flower buds of S. vulgaris, although both genders may still differ in plastid gene expression in specific tissues. We revealed the difference between the plastid transcriptomes of two S. vulgaris haplotypes in editing rate and in the coverage of several antisense transcripts. Our results document the variation in plastid genomes and transcriptomes in S. vulgaris.
