Authors: Singh Shivani , Yadav Poonam , Rani Rekha , Verma Urvashi 
Published: November 2014

ABSTRACT

Introduction
Abnormal uterine bleeding (AUB) is very common problem in patient attending outpatient department, especially in perimenopausal group.

Objective
To study prevalence of abnormal uterine bleeding and its type in perimenopausal women as well as to compare diagnostic efficacy of ultrasonography, hysteroscopy and histopathology.

Material and method
The study was carried out in Department of Obstetrics and Gynecology, Era Medical College, Lucknow, in 100 patient attending outpatient department with AUB in perimenopausal age group.

Observation
Most of the patients were multiparous, more than 50% belong to socioeconomic class III and IV and mean age was 43.05 ± 4.09 years. Commonest complaint was menorrhagia (45%) followed by metrorrhagia in 19% and menometorrhagia in 14%. Majority of patients (85%) had uterine volume between 151 and 250 cm3. Only three patient had uterine volume more than 252 cm3. Endometrial hyperplasia was diagnosed in 14% with ultrasonography, 11% on hysteroscopy while in 15% on hystopathological examination.

Conclusion
In perimenopausal women with AUB, ultrasonography should be first investigation because of its freely availability, noninvasiveness and cost effectiveness.

Clear Cell Carcinoma of Endometrium: A Clinical Review
Authors: Rawat Rajani , Vishwakarma Soniya , Seth Shikha , Kanti Vaibhav , Mishra Pragati 
Published: November 2014

ABSTRACT
Clear cell carcinoma of endometrium is a rare (1-6%) but aggressive malignancy with high propensity of early extra-uterine spread. The usual presentation is postmenopausal bleeding and discharge as with other endometrial cancers but it does not have preceding hyperplastic stage, instead it develops from thin atrophic endometrium, therefore impossible to identify by the screening measures like Pap smear and transvaginal sonography. First step for early diagnosis of such unfavorable endometrial cancer should be endometrial biopsy. Histopathological diagnosis is mandatory to confirm the clear cells present in the endometrial sample before planning the management. Clinical staging is highly erroneous in clear cell endometrial cancer and should not be taken into consideration in management plan. Being a rare cancer, there is lack of true evidence on its management protocol. Here, we had tried to provide the review about the clear cell endometrial (CCE) cancer diagnosis and management along with a case report for clinical perspective.

ABSTRACT
Transverse vaginal septum is a rare mullerian duct anomaly due to vertical fusion defect. A 21-year-old female presented with secondary amenorrhea and lower abdominal pain for 6 years. She had past history of hematocolpos due to transverse vaginal septum 6 years back and was operated twice for the same. First, the hematocolpos was aspirated, the tract was dilated and evacuation of hematocolpos was done. Fibrosis occurred after 2 months and amenorrhea persisted for 6 years. Second, incomplete resection of the fibrosed transverse vaginal septum was done and a mold was kept for 1 year. On examination, recurrent fibrosis of transverse vaginal septum leading to hematometra and hematocolpos was found. Complete resection of septum with double breasting of vaginal mucosa was done. Drain was kept in vagina for 7 days. Patient was advised to keep the mold for 1 and half year.

Published: November 2014

This study evaluated the control environment and monitoring activities components of Internal Control Systems of Ghanaian Banks using COSO’s principles and attributes of assessing the effectiveness of internal control systems. A five point Likert scale was used to measure respondent’s knowledge and perception of internal controls and the bank’s internal control system effectiveness. Responses ranged from strongly disagree to strongly agree, where 1 represented strongly disagree (SD) and 5 represented strongly agree (SA). Statistical Package for Social Sciences (SPSS) was used to analyse data and presented in the form of means and standard deviations for each question and each section of the questionnaire. The study found out that, strong controls exist in the control environment and monitoring activities components of the internal control systems of banks in Ghana. The two components were highly rated by respondents with average means of 4.72 and 4.66 respectively. The study recommended that boards of banks in Ghana should not be complacent about the findings but should work hard to ensure continuous ongoing and separate internal control monitoring to ascertain that controls really exist and are functioning properly.

Customer Loyalty has been realized as a significant aspect in the establishment and maintenance of competitive edge in services sectors. Firm’s performance is positively affected with customer loyalty. Customer Loyalty not only increases the business value but they also allow it to uphold costs lower than those associated with attracting new customers. Now days, banking sectors are promoting Relational marketing which is beneficial for them to build long-term relationship with their customers. Empirical research of this paper examines the extent to which customer Satisfaction in accordance with Perceived Service quality and Trust, Switching Cost, Corporate Image, Customer Involvement Influence the Customer Loyalty in banking sector. For this analysis, Questionnaires were distributed among 150 people and data were collected from 148 questionnaires selected through non-probability sampling technique. Regression and Correlation techniques were used for the analysis of this study. Findings show that there is a direct positive and significant relationship between Customer Satisfaction together with Perceived Service Quality, Corporate Image, Customer involvement and Customer Loyalty. While, Switching Cost has a positive but insignificant relationship on Customer Loyalty.
Isomorphic Categories
Authors: Ferguson Ryan , Homa Donald 
Published: November 2014

Abstract
Learning and transfer were investigated for a categorical structure that could be mapped without loss of information from 1 sensory modality to another. The category space was composed of 3 nonoverlapping, linearly separable categories whose members were structured, temporal events. Each stimulus was composed of a sequence of on–off events that varied in duration and number of subevents (complexity). Categories were learned visually, haptically, or auditorily and transferred to the same or another modality. Despite the isomorphism across modalities, significant differences appeared in both learning and transfer. The visual modality showed an early learning advantage, with information on the transfer test preserved best when encoded visually during learning, worst when encoded haptically, with auditory encoding intermediate. False recognition rates were elevated when categories were learned haptically and transferred to another modality. In general, classification accuracy was highest for the category prototype, with false recognition of the category prototype higher in the cross-modality conditions. The results are discussed in terms of current theories in modality transfer including the difficulties inherent when calculation of similarity must be considered in a cross-modal situation.
IMM: A Multisystem Memory Model for Conceptual Learning
Authors: Saleh Mai Sabry 
Published: November 2014

Abstract
Concepts of learning and memory are closely related, and the terms often describe the same processes. Conceptual learning is known to be the process of developing abstract rules or mental constructs based on sensory experience. The Integrated Model of Mind (IMM), introduced in the present work, is a theoretical multisystem memory model that describes how concepts are formed. The IMM in its design arranges memory systems after their function in an integrated and harmonized sequence. It provides answers to some limitations of Tulving’s serial–parallel– independent (SPI) model and suggests a new assumption with respect to mental representation and image schema construction through the process of encoding.

Published: November 2014

Abstract

Human bone marrow-derived stromal/stem cells (BMSCs) have great therapeutic potential for treating skeletal disease and facilitating skeletal repair, although maintaining their multipotency and expanding these cells ex vivo have proven difficult. Because most stem cell-based applications to skeletal regeneration and repair in the clinic would require large numbers of functional BMSCs, recent research has focused on methods for the appropriate selection, expansion, and maintenance of BMSC populations during long-term culture. We describe here a novel biological method that entails selection of human BMSCs based on NOTCH2 expression and activation of the NOTCH signaling pathway in cultured BMSCs via a tissue culture plate coated with recombinant human JAGGED1 (JAG1) ligand. We demonstrate that transient JAG1-mediated NOTCH signaling promotes human BMSC maintenance and expansion while increasing their skeletogenic differentiation capacity, both ex vivo and in vivo. This study is the first of its kind to describe a NOTCH-mediated methodology for the maintenance and expansion of human BMSCs and will serve as a platform for future clinical or translational studies aimed at skeletal regeneration and repair.
Southward displacement of the upper atmosphere zonal jet in the eastern north Pacific due to global warming
Authors: Park Jae‐Heung , An Soon‐Il 
Published: November 2014

AbstractThe jet stream over the eastern North Pacific (ENPJ) as a core of the atmospheric flow is known to strongly fluctuate meridionally, and its meridional displacement directly influences adjacent regional climate. Here, we investigate how this jet will be changed due to global warming. By analyzing the future scenario experiments of Climate Model Intercomparion Project Phase III (CMIP3) and Phase V (5), it was found that both ENPJ and the eastern tropical Pacific intertropical convergence zone (ITCZ) tend to move southward, which are closely related to the tropical eastern Pacific warming trend. Tropical eastern Pacific warming leads to not only the southward migration of ITCZ by southward‐shifting the off‐equatorial eastern Pacific warm pool, but also the southward shift of ENPJ by increasing baroclinic instability of the atmosphere in subtropical region through intensifying the meridional sea surface temperature (SST) gradient. Not primary but yet secondly the southward shift of ITCZ contributes to the southward shift of ENPJ through a kinematic connection bridged by local Hadley circulation.
Generation and propagation of ion cyclotron waves in nonuniform magnetic field: Application to the corona and solar wind

Published: November 2014

AbstractWith the objective to understand the generation, propagation, and nonlinear evolution of ion cyclotron waves (ICWs) in the corona and solar wind, we use electromagnetic hybrid (kinetic ions and fluid electrons) simulations with a nonuniform magnetic field. ICWs are generated by the temperature anisotropy of O5+ ions as minority species in a proton‐electron plasma with uniform density. A number of magnetic field models are used including radial and spiral with field strength decreasing linearly or with the square of the radial distance. O5+ ions with perpendicular temperature larger than parallel are initially placed in the high‐magnetic field regions. These ions are found to expand outward along the magnetic field. Associated with this expansion, ion cyclotron waves propagating along the magnetic field are also seen to expand outward. These waves are generated at frequencies below the local gyrofrequency of O5+ ions propagating parallel and antiparallel to the magnetic field. Through analysis of the simulation results we demonstrate that wave generation and absorption take place at all radial distances. Comparing the simulation results to observations of ICWs in the solar wind shows some of the observed wave characteristics may be explained by the mechanism discussed in this paper.

Authors: Singh Jasvinder A. , Ramachandran Rekha 
Published: November 2014

ObjectiveTo assess the association of hospital procedure volume for total shoulder arthroplasty (TSA) with patient outcomes and complications.MethodsWe used the US Nationwide Inpatient Sample from 1998–2011 to study the association of hospital annual TSA procedure volume with patient characteristics and TSA outcomes, including discharge disposition (home versus inpatient facility), length of index hospitalization, postarthroplasty periprosthetic fracture, and revision. Annual hospital TSA volume was categorized as <5, 5–9, 10–14, 15–24, and ≥25 TSA procedures annually.ResultsPatients receiving TSA at higher volume hospitals were more likely to be female (P < 0.0001) and white (P < 0.0001). Compared to low volume hospitals (<5, 5–9, or 10–14 procedures annually), patients receiving TSA at higher volume hospitals (15–24 or ≥25 procedures annually) had significantly lower likelihood of being discharged to an inpatient medical facility: 16.5%, 13.4%, 13.0%, 12.7%, and 11.5%, respectively (P < 0.0001); hospital stay above the overall median: 46.6%, 40.4%, 36.6%, 34.4%, and 29.2%, respectively (P < 0.0001); postarthroplasty fracture: 1.2%, 0.8%, 0.9%, 0.6%, and 0.8%, respectively (P = 0.0004); blood transfusion: 8%, 7.1%, 6.7%, 7.1%, and 5.5%, respectively (P = 0.006); and TSA revision: 0.5%, 0.3%, 0.2%, 0.3%, 0.3%, respectively (P = 0.045).ConclusionIn this study, we found that higher annual hospital TSA volume was associated with better TSA outcomes in the US. These findings document the impact of annual hospital TSA volume on TSA outcomes. Patients, surgeons, and policy‐makers should be aware of these findings and take them into account in decision‐making, policy decisions, and resource allocation.
Biomimetic Synthesis of the Calcineurin Phosphatase Inhibitor Dibefurin
Authors: Ellerbrock Pascal , Armanino Nicolas , Trauner Dirk 
Published: November 2014

AbstractDibefurin is a Ci‐symmetric natural product that acts as an inhibitor of calcineurin phosphatase. A six‐step synthesis of this compound is reported, which features an oxidative dimerization of the aromatic polyketide epicoccine as the key step. Dibefurin is proposed to be related to epicolactone, a complex yet racemic fungal metabolite that has recently been discovered. Attempts to access epicolactone from epicoccine and epicoccone B resulted in an unusual dimer that is formed through a hetero‐Diels–Alder reaction of a para‐quinone methide with an ortho‐quinone.
Bifunctional Catalysts Based on m‐Phenylene‐Bridged Porphyrin Dimer and Trimer Platforms: Synthesis of Cyclic Carbonates from Carbon Dioxide and Epoxides

Published: November 2014

AbstractHighly active bifunctional diporphyrin and triporphyrin catalysts were synthesized through Stille coupling reactions. As compared with a porphyrin monomer, both exhibited improved catalytic activities for the reaction of CO2 with epoxides to form cyclic carbonates, because of the multiple catalytic sites which cooperatively activate the epoxide. Catalytic activities were carefully investigated by controlling temperature, reaction time, and catalyst loading, and very high turnover number and turnover frequency were obtained: 220 000 and 46 000 h−1, respectively, for the magnesium catalyst, and 310 000 and 40 000 h−1, respectively, for the zinc catalyst. Results obtained with a zinc/free‐base hybrid diporphyrin catalyst demonstrated that the Br− ions on the adjacent porphyrin moiety also function as nucleophiles.

ABSTRACTTorrefied almond shells and wood chips were incorporated into polypropylene as fillers to produce torrefied biomass‐polymer composites. The composites were prepared by extrusion and injection molding. Response surface methodology was used to examine the effects of filler concentration, filler size, and lignin factor (relative lignin to cellulose concentration) on the material properties of the composites. The heat distortion temperatures, thermal properties, and tensile properties of the composites were characterized by thermomechanical analysis, differential scanning calorimetry, and tensile tests, respectively. The torrefied biomass composites had heat distortion temperatures of 8–24°C higher than that of neat polypropylene. This was due to the torrefied biomass restricting mobility of polypropylene chains, leading to higher temperatures for deformation. The incorporation of torrefied biomass generally resulted in an increase in glass transition temperature, but did not affect melting temperature. Also, the composites had lower tensile strength and elongation at break values than those of neat polypropylene, indicating weak adhesion between torrefied biomass and polypropylene. However, scanning electron microscopy results did indicate some adhesion between torrefied biomass and polypropylene. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41582.
