Published: February 2015

In general, the use of standalone screen (SAS) completion has significant economic (cost saving) and productivity (skin) advantages compared to the conventional open hole gravel pack (OHGP) completion. However, SAS completion, especially in horizontal gas well with high potential of sanding typically suffers from premature failure due to sand erosion caused by high annular velocity near the heel section.
This paper describes the work conducted to understand in detail and quantify the erosion risks on SAS in horizontal gas well and the proof-of-concept assessment of using swelling elastomer packers to segmentize the flow in the annulus as a mean to reduce erosion risks near the heel. The work involves carefully designed and selected experimental and Computational Fluid Dynamics (CFD) simulation work programs that focused on development of erosion model at room and elevated temperature, understanding and validation of sand screen failure using the developed erosion model, and CFD simulation and validation of gas flow profile in basepipe and annulus sections to understand the effect of flow segmentizers in reducing annulus velocity.
From this work, an improved sand erosion model was developed based on the Cylinder-In-Pipe methodology for the sand screen materials and downhole sand Particle Size Distribution (PSD) combinations at room and elevated temperature. Conditions that led to the failure of sand screen filter due to erosion damage were also established through the Sample-In-Pipe experiments. Validation of erosion on one-metre length of screen shows that CFD, combined with sound experimental techniques, can provide accurate prediction of sand screen material metal loss due to sand impact. CFD simulation of gas flow in horizontal gas well completion were conducted in order to provide further insights and confidence in using flow segmentizers to control annular velocity.
Finally, a pilot application of the concept in a gas field in Malaysia, based on integration of all the findings will be presented together with comparison to a similar well within the same field but completed with OHGP completion showing that the SAS with flow segmentizers concept has led to significant CAPEX savings and high well productivity.

Abstract
Human CMV (HCMV) infection promotes a variable and persistent expansion of functionally mature NKG2Cbright NK cells. We analyzed NKG2Cbright NK cell responses triggered by Abs from HCMV+ sera against HCMV-infected MRC5 fibroblasts. Specific Abs promoted the degranulation (i.e., CD107a expression) and the production of cytokines (TNF-α and IFN-γ) by a significant fraction of NK cells, exceeding the low natural cytotoxicity against HCMV-infected targets. NK cell–mediated Ab-dependent cell-mediated cytotoxicity was limited by viral Ag availability and HLA class I expression on infected cells early postinfection and increased at late stages, overcoming viral immunoevasion strategies. Moreover, the presence of specific IgG triggered the activation of NK cells against Ab-opsonized cell-free HCMV virions. As compared with NKG2A+ NK cells, a significant proportion of NKG2Cbright NK cells was FcεR γ-chain defective and highly responsive to Ab-driven activation, being particularly efficient in the production of antiviral cytokines, mainly TNF-α. Remarkably, the expansion of NKG2Cbright NK cells in HCMV+ subjects was related to the overall magnitude of TNF-α and IFN-γ cytokine secretion upon Ab-dependent and -independent activation. We show the power and sensitivity of the anti-HCMV response resulting from the cooperation between specific Abs and the NKG2Cbright NK-cell subset. Furthermore, we disclose the proinflammatory potential of NKG2Cbright NK cells, a variable that could influence the individual responses to other pathogens and tumors.
HDlive in the Assessment of Fetal Facial Abnormalities
Authors: Tanaka Hirokazu , Uematsu Rina 
Published: February 2015

ABSTRACT
We present the latest HDlive images of normal fetal faces and facial abnormalities. Fetal facial anatomical structures, such as the eyes, nose, ears and mouth, are clearly evident at 12 to 13 weeks of gestation. HDlive with the use of new skin-like colors provides sonographers and physicians with a natural and anatomically realistic appearance of the fetal face. Moreover, HDlive images provide entirely new visual experiences for obstetricians owing to the anatomically realistic depiction of the normal fetal face and fetal facial abnormalities in utero. HDlive can provide clearer facial images than conventional three-dimensional (3D) sonography. In particular, HDlive is superior to conventional 3D sonography for the depiction of fetal eyes because of its shadowing effect. HDlive may be a useful diagnostic modality for the antenatal evaluation of normal fetal facial anatomy and fetal facial abnormalities.

HDlive in the Assessment of Fetal Intracranial, Intrathoracic and Intra-abdominal Anomalies
Authors: Hata Toshiyuki 
Published: February 2015

ABSTRACT
We present a series of images of different fetal intracranial, intrathoracic and intra-abdominal anomalies reconstructed using HDlive. It is a novel three-dimensional (3D) ultrasound modality that can provide the operator with naturally realistic features of any fetal anomalies. HDlive and its inversion mode are applied in several cases and two-dimensional (2D) sonographic images of different anomalies are also presented clearly to compare the advantages of HDlive in this article. This review focuses on the role of HDlive in the presence of such anomalies. HDlive should be a very useful aid in adjunct to other ultrasound modalities, specifically in cases that warrant detailed information. It can also be useful for the antenatal surveillance of anomalies, such as cystic lesions that may progress to complications. This innovative tool offers many promising advantages in clinical practice and future research on fetal anomalies.

HDlive for Assessment of Placenta and Umbilical Cord
Authors: Tanaka Hirokazu , Mashima Masato 
Published: February 2015

ABSTRACT
We present the latest HDlive images of normal and abnormal placentas and umbilical cords. By means of HDlive, more detailed information on placental and umbilical cord abnormalities can be obtained, because this technique is a new surfacerendering mode that uses an adjustable light source to create lighting and shadowing effects, thereby increasing depth perception. HDlive provides extraordinarily realistic imaging of the placenta and umbilical cord, making it almost impossible to differentiate between fetoscopic findings and ultrasound scans. This novel technique may assist in evaluation of the placental and umbilical cord anatomy, and offer potential advantages over conventional two- and three-dimensional ultrasound. HDlive may be an important modality in future placental and umbilical cord research and in the evaluation of their abnormalities.

Three-dimensional Power Doppler Ultrasound Study of the Placenta
Authors: Hata Toshiyuki , Cajusay-Velasco Sarah 
Published: February 2015

ABSTRACTAdvanced ultrasound technology has been a valuable tool in the assessment of placental anatomy and physiology. Conventional two-dimensional (2D) sonography reveals placental morphological characteristics, 2D color Doppler can assess blood flow in the placenta, 2D power Doppler can evaluate placental vascular trees, and three-dimensional (3D) ultrasound gives more detailed information on the surface anatomy. Recent advances, such as 3D power Doppler with virtual organ computer aided-analysis (VOCAL) and histogram analysis can measure the placental volume, and assess uteroplacental and fetoplacental perfusions. In particular, ‘placental vascular sonobiopsy’ can specifically evaluate the second- and thirdtrimester placental blood flow and vascularity by obtaining several spherical samples from the placenta that will represent the entire placenta. This article presents normal placental development and pathological findings of the placenta using 3D power Doppler ultrasound, and discusses 3D power Doppler assessments of placental perfusion in high-risk pregnancies, such as fetal growth restriction, pregnancy-induced hypertension and preeclampsia, and, from this basis, re-establishes the importance of 3D power Doppler ultrasound as a screening, diagnostic, and surveillance tool in normal and abnormal pregnancies.How to cite this articleTanaka H, Cajusay-Velasco S, Noguchi J, Hata T.

Published: February 2015

ABSTRACTWe present the latest HDlive images of uterine and adnexal tumors. Evaluation of these tumors with conventional twodimensional (2D) sonography has been the standard procedure for morphologic assessment, but the introduction of threedimensional (3D), power Doppler and other recent modalities has been of great help in providing more specific details, especially in characterizing malignancy. HDlive is the latest ultrasound modality that enhances 3D and four-dimensional images. Several different gynecologic tumors were assessed using HDlive in this study. HDlive can provide realistic features of the inner surfaces and contents of tumors which are very similar to the gross specimens. An accurate characterization of gynecologic tumors is important when deciding on clinical management options. Therefore, HDlive may be a valuable tool in adjunct to other imaging modalities to achieve an accurate preoperative diagnosis.How to cite this articleKanenishi K, Cajusay-Velasco S, Mashima M, Tanaka T, Hanaoka U, Hata T.

Luteinizing Hormone in Controlled Ovarian Stimulation
Authors: Vohra Arveen 
Published: February 2015

ABSTRACTThe role of follicle stimulating hormone (FSH) in assisted reproductive technology is well understood, though there is still no published consensus on the need for exogenous luteinizing hormone (LH) in controlled ovarian stimulation. There is a dilemma regarding the usefulness of LH supplementation in controlled ovarian stimulation despite growing understanding of the LH and FSH interrelation and their effects on fertilization and implantation. This review revisits the physiological role of LH, LH receptors and the concept of LH therapeutic window. With the availability of LH activity from different sources, there is a need to understand the differences between recombinant human LH (r-HLH), human menopausal gonadotropin and human chorionic gonadotropin (hCG). It has been observed that adjuvant r-HLH provides precise control over the dose of LH bioactivity administered to target the therapeutic window. This review discusses about the various patient subgroups that may benefit from LH supplementation. The use of r-HLH is recommended in women with poor response in a previous cycle or suboptimal follicular growth in an ongoing ovarian stimulation cycle by day 6 to 8 of stimulation. Exogenous LH administration should also be considered in women at risk of suboptimal response, specifically age > 35 years and women treated with GnRH analogues (agonists or antagonists) during ovarian stimulation causing over suppression of endogenous LH and FSH pituitary secretion. Further research is needed to identify LH polymorphisms, adequate dosing, cost efficacy, need for rLH and hCG supplementation in different patient profiles for maximum benefit during controlled ovarian stimulating (COS).How to cite this articleVohra A, Rao KA.

Role of Midtrimester Localization of the Placenta in predicting Pregnancy Outcome
Authors: Faizi Shaweez , Pai Muralidhar V 
Published: February 2015

ABSTRACTThe localization of the placenta by ultrasound in the second trimester has been hypothesized to have an impact on the pregnancy, in terms of antenatal, intrapartum and postnatal outcome.ObjectiveTo evaluate the role of placental location in predicting the pregnancy outcome.Materials and methodsIt was a prospective observational study conducted between September 2011 and March 2013 at a tertiary care hospital. Placental location, as determined by midtrimester ultrasound in 620 antenatal women, was divided into five groups—anterior, posterior, fundal, lateral and low lying placenta-depending on where > 75% of the placental mass was located. Outcome variables, such as antenatal complications, intrapartum events and neonatal outcome in these women were studied.ResultsOut of 620 women, 274 (44.1%) had anterior, 169 (27.2%) had posterior, 98 (15.8%) had fundal, 61 (9.8%) had lateral placentae and 18 (2.9%) had placenta previa as per the last scan done at 28 weeks. Pre-eclampsia (27.9%) and antepartum hemorrhage (19.7%) were more common in lateral placenta whereas term prelabor rupture of membranes (11.2%) was more common in fundal placenta and these findings were statistically significant. The incidence of intrauterine growth restriction (IUGR) was also found to be higher in patients with lateral (16.4%) and posteriorly (16%) implanted placenta although there was no statistically significant association.ConclusionAmong the various placental sites of implantation, lateral location of the placenta is associated with adverse antenatal outcomes like pre-eclampsia, antepartum hemorrhage and IUGR.How to cite this articleFaizi S, Pai MV.

ABSTRACTPartial vaginal agenesis with transverse vaginal septum is rare malformation of female genital system. The reported incidence of vaginal atresia is 1:4000 to 5000 live female birth. The incidence of septum in upper one-third is 46%, middle 35%, lower 19%. Transverse vaginal septum occurs due to defect in vertical fusion of mullerian ducts during embryogenesis. Vaginal atresia occurs due to failure of canalization of sinovaginal bulbs.We are presenting such a rare case of partial vaginal agenesis with transverse vaginal septum.The aim of this presentation is to make the consideration of transverse vaginal septum and vaginal atresia in young girls with cryptomenorrhea and to emphasize on is meticulous evaluation and diagnosis with counselling of a minor along with parents of future reproductive outcome along with surgical difficulties anticipation and difficulties post vangioplasty.How to cite this articleMuralidhar L, Venkatesh S, Pandey P.

Trademark Protection in Bankruptcy Proceedings: A Closer Look at Lubrizol and its Progeny
Authors: Vereen Endia 
Published: February 2015

When the worlds of bankruptcy and intellectual property licenses converge, licensees are placed in potentially dangerous positions. The seminal case on this issue, Lubrizol Enterprises, Inc. v. Richmond Metal Finishers, Inc., stands for the proposition that when a licensor rejects an intellectual property license as "executory," the licensee no longer has the right to rely on provisions within the agreement with the debtor for continued use of the technology. To countermand the negative effects of Lubrizol, Congress amended the Bankruptcy Code, but intentionally omitted trademarks from the definition of intellectual property. This omission has produced a string of conflicting case law, leaving trademark licensees in a precarious position with few options for recourse. This Note discusses the Intellectual Property Bankruptcy Protection Act and trademark protection specifically, and details the circuit split created by Sunbeam Products, Inc. v. Chicago American Manufacturing. This Note focuses on the implications of the circuit split, and concludes by providing some suggestions for how courts can resolve this issue in the future.
The People Versus the Powers; or, On Money and Speech The Continuing Saga of Campaign Finance Reform
Authors: RUPRECHT LOUIS A. 
Published: February 2015

Abstract
Two of the most significant threats to democratic governance at the national level are, first, the gerrymandering of congressional districts, which has tempted primary candidates in increasingly “safe” districts to present themselves as extremists unwilling to compromise, and, second, the Supreme Court decisions (Citizens United v. FEC and McCutcheon v. FEC) that have effectively opened the electoral process to virtually unlimited campaign contributions from increasingly anonymous, and therefore unaccountable, donors and behind-the-scenes political actors. This article examines the particulars of the recent McCutcheon decision and uses a recent book by retired U.S. Supreme Court justice John Paul Stevens to explore the possibility of constitutional reform aimed against these developments.
Thinking About Religion Before ‘Religion’: A Review of Brent Nongbri'sBefore Religion: A History of a Modern Concept
Authors: BROUCEK JAMES 
Published: February 2015

AbstractProponents of the view that religion is a socially constructed concept frequently argue that historians should not write about religion in the premodern world. Brent Nongbri's Before Religion nuances this argument by distinguishing between issues of translation and issues of historiography. Like other social constructionists, Nongbri argues that historians cannot defensibly translate words from premodern source languages as ‘religion’. He maintains, however, that historians can defensibly write about premodern religions, so long as they write redescriptive histories: narratives that explicitly treat ‘religion’ as a modern, anachronistic category that the historian applies to premodern materials for explanatory purposes. This review challenges both parts of Nongbri's argument. Historians are entitled to translate premodern terms as ‘religion’, and social constructionists of religion are better off abandoning Nongbri's distinction between descriptive and redescriptive histories. All histories are redescriptive, in Nongbri's sense, making histories of premodern religions less exotic and less problematic than many imagine.

Published: February 2015

AbstractBackground and aimSeveral papers have shown that preoperative inflammation‐based prognostic scores and/or immunonutritional status are associated with survival in patients with hepatocellular carcinoma (HCC). However, the validity of prognostic factors of these scores remains controversial. This study aimed to validate the power of prognostic scores based on the preoperative inflammatory and immunonutritional indices of patients who underwent hepatectomy for HCC with curative intent.MethodsClinicopathological parameters and inflammation‐based prognostic scores and immunonutritional status, including the Glasgow Prognostic Score, neutrophil to lymphocyte ratio (NLR), and prognostic nutritional index (PNI), were retrospectively analyzed to identify the predictors of overall and recurrence‐free survival in 256 patients.ResultsIn multivariate analysis, NLR was an independent prognostic factor for overall, and recurrence‐free survival (hazard ratio [HR] 2.59, 95 % confidence interval [CI] 1.56–4.31, P < 0.001, and HR 2.11, 95 % CI 1.44–3.11, P < 0.001, respectively). Additionally, PNI was an independent predictor of overall survival (HR 2.01, CI 1.21–3.36, P = 0.007).ConclusionsThe present study shows that the NLR and PNI based on preoperative inflammatory and immunonutritional indices are predictors of overall survival in patients who undergo hepatectomy for HCC with curative intent.

AbstractBackgroundThe present study was performed to determine whether thyroidectomy patients undergoing general anesthesia provided with a laryngeal mask airway (LMA) have a lower risk of voice‐related complications and laryngopharyngeal symptoms than those undergoing endotracheal intubation (ETI).Materials and methodsIn a prospective, double‐blinded, randomized clinical trial, we studied 64 patients undergoing elective thyroid lobectomy between July 2013 and February 2014. Acoustic analyses were performed preoperatively and at 48 h and 2 weeks postoperatively. The voice handicap index (VHI), M.D. Anderson dysphagia index (MDADI), and laryngopharyngeal symptom score (LPS) were determined preoperatively and at 24 h, 48 h, 1 week, and 2 weeks post‐thyroidectomy.ResultsIn acoustic analysis, jitter, shimmer and noise‐to‐harmonic ratio showed significantly better results in the LMA group than the ETI group 48 h after surgery, but there was no difference at 2 weeks. The incidence of postoperative lower‐pitched voice in the LMA group was also significantly lower than that in the ETI group. In the LMA group, the VHI, MDADI, and LPS were better compared to those in the ETI group at 24 h postoperatively, and improved to the preoperative state within 1 week. However, those in the ETI group remained poorer than the preoperative values 1 week after surgery.ConclusionsUse of the LMA in general anesthesia for thyroid surgery has advantages over the ETI in decreasing patients’ subjective and objective voice symptoms, reducing the duration of symptoms, and relieving the laryngopharyngeal symptoms.
