Time-Dependent Extracellular Matrix Organization and Secretion from Vascular Endothelial Cells due to Macromolecular Crowding
Authors: Liu Frances D. , Zeiger Adam S. , Van Vliet Krystyn J. 
Published: February 2016

ABSTRACTInteractions between biological cells and surrounding extracellular matrix (ECM) materials modulate many cell behaviors including adhesion and migration. One key example of this cellmatrix reciprocity is in the context of angiogenesis, the sprouting of new blood vessels from preexisting vasculature. Vascular endothelial cells (VECs) create and remodel the ECM during this process. In vivo, the surrounding fluid environment includes high concentrations of macromolecules, and is considered “crowded” in comparison to in vitro environments. Here, we quantified the amount and organization of collagen IV, a prominent ECM component of VECs, that was produced by these cells over four weeks in vitro in the presence or absence of macromolecular crowder (MMC) nanoparticles that approximated in vivo crowding. In the presence of MMCs, the amount and degree of alignment of collagen IV was greater. This ECM difference emerged within one week and was sustained for over four weeks. We explored the effect of initial cell density (cells/µm2) on this matrix production, to consider potential differences at a wound site versus an intact vessel. Moreover, we found the biophysical effect of MMCs to be unmodulated by secretions from an adjacent cell type in microvessels (pericytes). These results suggest that macromolecular crowding plays a direct role in remodeling the basement membrane, and that such crowding can be induced in vitro to more closely approximate the cell microenvironment.
Changes in rheology of self-consolidating concrete induced by pumping

Published: February 2016

Abstract
Pumping is an easy and flexible process to place concrete inside a formwork. Many studies have recently been performed to understand and optimize the pumping process and identify the main differences between pumping of conventional vibrated concrete and self-consolidating concrete (SCC). However, due to pumping, changes in fresh concrete properties and the air-void system have been noticed. This paper describes the consequences of pumping on the fresh properties of SCC by means of two experimental pumping campaigns. In many cases, the concrete undergoes a large shear rate in the pipe, thus (re-)dispersing cement particles. This is expected to be the main cause of the observed decrease in plastic viscosity, V-Funnel flow time and pumping pressure resulting from increased flow rate or pumping time. The changes in yield stress or slump flow are anticipated to be influenced by the same phenomenon, but the final outcome is assumed to depend on the availability of residual superplasticizer in the mixing water. Pumping can cause a stable SCC to become segregating if both the yield stress and plastic viscosity decrease, or it can provoke a significant loss in filling ability, passing ability and self-consolidation of the concrete if the yield stress increases dramatically.

Published: February 2016

Introduction: Research has shown that the number of children and adolescents experiencing emotional difficulties such as anxiety is escalating, especially for those groups at risk. Living in an orphanage has been considered a risk factor for delays in an individuals’ social, emotional and behavioral development. Objective: The aim of this study was to evaluate the effectiveness of the Spanish version of the FRIENDS program, a CBT-based resilience program, with 57 girls from low socioeconomic status (SES) background that were living in an orphanage. Method: Participants received the program for 10 consecutive weeks, and pre- and post-test measures were collected. Measures evaluated participants’ anxiety symptoms, level of self-concept, hope, coping skills, and psychosocial difficulties. Social validity was also assessed. Results: Results showed positive changes, including a decrease in anxiety symptoms and psychosocial difficulties, as well as an increase in their proactive coping skills. Several subscales and items of the self-concept and hope outcome measures also reported statistically significant improvements. Conclusions: Participants and parents/caregivers reported that the program was both enjoyable and useful. Implications of the findings and directions for further research are discussed.
Correlatos cognitivos y neuropsicológicos de los cinco grandes: una revisión en el área de la neurociencia de la personalidad
Authors: Restrepo Jorge Emiro 
Published: February 2016

Introducción: la neurociencia de la personalidad es un área de estudio de origen relativamente reciente. Objetivo: estudiar los fundamentos neurobiológicos y neuropsicológicos de la personalidad. Metodología: este es un artículo de revisión narrativa en el cual se presentan y discuten algunas, quizás la mayoría, de las investigaciones realizadas en esta área. La estructura del artículo está en función de los cinco grandes factores de la personalidad. Para cada factor (neuroticismo, extraversión, apertura, amabilidad y responsabilidad), se revisa y discute la literatura existente en relación con los correlatos neuropsicológicos en la función ejecutiva, la memoria y la inteligencia. Resultados: por ser un área de estudio reciente y a razón del tipo de revisión llevado a cabo, no es posible realizar una conclusión precisa, es decir, no es posible establecer, en el estado del arte actual, cómo se correlacionan los factores y las facetas de la personalidad con la función ejecutiva, la inteligencia y la memoria. Conclusión: en términos generales, puede afirmarse que existe un perfil neuropsicológico diferente para cada uno de los factores.

Abstract
Haematuria is not uncommon in people with haemophilia and is mainly caused by spontaneous haemorrhage or trauma. The frequency and clinical significance of urinary schistosomiasis in the aetiology of haematuria among haemophiliacs in schistosomiasis endemic countries such as Nigeria have not been previously studied. We retrospectively analysed the clinical and laboratory data of 45 haemophiliacs with haematuria in Nigeria with the aim of determining the frequency of urinary schistosomiasis and other causes of haematuria among haemophiliacs, the haematological profiles of haemophiliacs with haematuria and the severity of schistosomal haematuria relative to non-schistosomal haematuria. Haematuria was due to spontaneous haemorrhage in 23 (51.1%) patients, trauma in 14 (31.1%) patients and schistosomiasis in 8 (17.8%) patients. There were no significant differences in mean values of haematological parameters between patients with spontaneous and traumatic haematuria. However, compared to patients with spontaneous and traumatic haematuria, patients with schistosomal haematuria had significantly lower mean Hb concentration (8.5 vs.11 and 11.5g/dL; p<0.05) and significantly higher mean eosinophil count (0.42 vs. 0.21 and 0.2×109/L; p<0.05). This study revealed that schistosomiasis was responsible for 17.8% of cases of haematuria in northern Nigerian haemophiliacs. Schistosomal haematuria was severe and caused significant anaemia in contradistinction to spontaneous and traumatic haematuria that were mild and did not cause significant anaemia. A superimposed pro-haemorrhagic host-parasite relationship was responsible for the severe haematuria seen in haemophiliacs with schistosomiasis, a situation that would potential increase their risk of iron deficiency and its attendant consequences including childhood cognitive impairment. Haemophiliacs with haematuria in schistosomiasis endemic countries should be investigated by urinalysis for early detection and treatment. Haemophiliacs who present with haematuria in association with eosinophilia should evoke the strongest clinical suspicion for schistosomiasis. Parents of haemophiliacs should be counseled on how to protect their children from exposures to infected waters.
Septo-Optic Dysplasia: A Case Study
Authors: Musgrove Jamie M. , Riley Cheryl 
Published: February 2016

AbstractSepto-optic dysplasia (SOD) is a rare congenital heterogeneous malformation. SOD was formerly known as de Morsier syndrome, which associated a midline brain defect such as an absent septum pellucidum with optic nerve hypoplasia. The diagnosis of SOD is made when there are two or more characteristics of the classic triad. The triad consists of optic nerve hypoplasia, pituitary hormone abnormalities, and midline brain defects, although it can vary in the severity of clinical presentation and phenotype. The purpose of this article is to review a case and analyze the literature regarding prevalence, etiology, clinical presentation, diagnosis, and management of SOD.

Our research intention was to categorize the constructs of the following fundamental concept: “promotion metrics’ assumptions through the key features of critical reflection”. The literature review findings indeed revealed us very new constructs and established an initial understanding of the constructs and their relationship to other constructs regarding to Mezirow’s perspective of Transformative Learning Theory (TLT) regarding to the application as a framework of promotion metrcs’ assumptions in terms of a promotion campaign assessment and evaluation. Practical implications of the extension of Mezirow’s perspective of TLT are introduced for promotion managers. </span></p></div></div></div></div>
The (Non)Performance Of Kiplinger‟s Expert Recommendations
Authors: Borghesi Richard , Pencek Thomas 
Published: February 2016

We examine the performance of 1,572 stock recommendations published over the past 10 years by Kiplinger’s Personal Finance magazine. Kiplinger’s picks earned a risk-adjusted mean abnormal monthly return of -2.58% over the 6-month post-pick period. Our analysis indicates that the recommended firms were larger than average, and that the non-risk-adjusted returns of these stocks exceeded market returns prior to being selected. The poor post-pick performance cannot be attributed to a small subset of stocks or to a particular time frame. Instead, the experts appear to significantly underperform throughout much of the period examined. Our findings suggest that the experts of some popular investment periodicals may bias their analyses in favor of hot stocks to appeal to the interests of naïve subscribers.
Exploring Israeli Venture Capital Investing In Renewable Energy
Authors: Blum David A. 
Published: February 2016

Israel’s venture capital market is one of the largest in terms of capital investing in the world. However, in 2014, 5 of 83 independent venture capital firms located in Israel invested in renewable energy portfolio companies. The result of investing in few renewable energy firms in Israel is a continued reliance on imported fossil fuels from geographically distant nations. The importation of fossil fuels creates an added security risk in an already hostile political environment. The gap in research addressed in this paper explored factors for the small number of renewable energy firms receiving venture capital funding in Israel. The research question guiding this study was what are the factors for the small number of renewable energy firms receiving funding in Israel. The lack of renewable energy firm funding appears to be as a result of three factors. First is low return on investment. Second is regulatory uncertainty from the Israeli government. Third is the lack of knowledge of renewable energy by independent venture capitalists.

Gender and marital violence: points of view from a specialized Justice System
Authors: Magalhães Nayara 
Published: February 2016

O sistema de justiça tem sido alvo de reflexões acerca de sua eficiência e credibilidade frente às demandas das mulheres. Com as pressões dos movimentos feministas para visibilizar a violência doméstica, conjugal e familiar, o Estado tem sido pressionado a criar medidas e espaços especiais para o enfrentamento dessa problemática. A partir desse cenário, a propos- ta desse trabalho é apresentar uma pesquisa que re- vele nuances do sistema de justiça especializado do Distrito Federal, por meio da Delegacia Especial de Atendimento à Mulher, de Promotorias de Violência Doméstica e Familiar contra a Mulher e de Juizados de Violência Doméstica e Familiar contra a Mulher. Foram feitos estudos de caso e análise de conteúdo a partir dos registros de entrevistas com delegadas de polícia, promotores de justiça e juízas de direito em que foram analisadas percepções pessoais, profissionais, legais, teóricas, estatais e sistêmicas de oito pro- fissionais inseridos/as nesse sistema. O objetivo foi compreender como se dá a interação dessas pessoas com a Lei Maria da Penha, com os estudos de gênero e violência, com sujeitos inseridos em situação de violência e com o próprio sistema de justiça. Identi- ficamos algumas reflexões críticas sobre a condição da mulher e as desigualdades de gênero nas relações sociais e afetivas, todavia, alguns resquícios da cultura patriarcal legitimadora da violência fizeram-se presentes.
Design and In-Vitro Evaluation of Colon Targeted Prednisolone Solid Dispersion Tablets
Authors: Sura Zuhair Mahmood Alkazzaz  , Wedad Kamal Ali  
Published: February 2016

In the present investigation an attempt was made to prepare colon targeted enteric coated tablet containing different prednisolone solid dispersion formulations, to prevent ulcerative colitis, improve the patient compliance and reduce the side effects of drug in the gastro intestinal tract (GIT). Solid dispersion is one of the most widely used approaches to enhance the solubility as well as dissolution rate of poorly water soluble drugs. Solid dispersions (SDs) of Prednisolone with D-mannitol, PEG 4000 and Kollicoat IR were prepared and evaluated to deliver Prednisolone to the colon in a pre-solubilized form. The selected formula using drug compatible excipients was compressed into fast disintegrating tablets and then coated with Eudragit S100 (pH-responsive polymer), several variables related to both solid dispersion preparation (carrier type and drug to the carrier ratio) and tablet coating (coat level) were studied to show their effects on drug solubility and dissolution. Different analytical techniques like differential scanning caloremitry (DSC), powder x-ray diffraction (PXRD) and scanning electron microscopy (SEM) were studied to prove the change of drug particle from crystal to amorphous form in SDs. The 1:3 Prednisolone/Kollicoat IR SDs showed the greatest improvement in the dissolution rate. The coating level was critical for determining the duration of the lag phase. Best result was given by the 16% coat (Eudragit S100/ Dibutyl phthalate/ talc). This coating level showed an acceptable lag time for the proposed colonic targeting (5 h) as the selected tablet resisted pre-colonic pH values, followed by an immediate release stage in pH 7.4. The suggested covered (coated) tablets may provide a colonic delivery system for prednisolone with enhanced solubility and bioavailability.
Shewhart Control Chart in Microbiological Quality Control of Purified Water and its Use in Quantitative Risk Evaluation
Authors: Mostafa E. Eissa  
Published: February 2016

Water in pharmaceutical industry is a key ingredient in many industrial processes, including machine washing and preparation of most medicinal products. The process of regular monitoring for the microbiological quality of water at the points of use is a critical aspect in ensuring the compliance to the limit. However, the full value of the microbiological control could be accomplished by the use of control charts and statistical quality control to show the trend and behavior of bioburden. In addition, Shewhart charts provide insight for prediction of the future of the water quality. In the current study, purified water samples were analyzed microbiologically during a two-year period. The generated data were continuously interpreted using statistical software packages. The trend indicated that two regions in Shewhart chart were in the out-of-control state at these periods generating either out-of-trend (OOT) and/or out-of-specification (OOS). Investigations showed that these deteriorations in the performance were chronologically coincided with unusual rise in the microbial count of city water, although there was no direct correlation between the input and output water microbiologically. The rate of failure of product purified water was determined to be 7.69x10-4 and Ppk was 1.06 which were unsatisfactory performance. However, by removing the excursion periods due to the expected extraneous causes from the I-MR chart, a 337 times increase in the process performance was estimated with Ppk index of 1.53 and quantitative performance failure risk (QPR) equals 2.28x10-6. This finding highlighted the criticality of the quality of the feed city water and its impact on the final purified water. Thus, the processing stages in the water purification plant are not absolute barriers against microbial creeping into the distribution system, and the purification system of water has a certain tolerance limit after which an outbreak of microbial population occurs and hence compromising the system efficacy and performance. From the present study, it is recommended to design protective pretreatment system that buffers severe fluctuations in raw water quality so that water station possesses the ability to work optimally in an attempt of delivering safe water for medicinal and pharmaceutical manufacturing purposes.
