Decreased β-Cell Proliferation and Vascular Density in a Subpopulation of Low-Oxygenated Male Rat Islets
Authors: Ullsten Sara , Lau Joey , Carlsson Per-Ola
Published: June 2019

Low-oxygenated and dormant islets with a capacity to become activated when needed may play a crucial role in the complex machinery behind glucose homeostasis. We hypothesized that low-oxygenated islets, when not functionally challenged, do not rapidly cycle between activation and inactivation but are a stable population that remain low-oxygenated. As this was confirmed, we aimed to characterize these islets with regard to cell composition, vascular density, and endocrine cell proliferation. The 2-nitroimidazole low-oxygenation marker pimonidazole was administered as a single or repeated dose to Wistar Furth rats. The stability of oxygen status of islets was evaluated by immunohistochemistry as the number of islets with incorporated pimonidazole adducts after one or repeated pimonidazole injections. Adjacent sections were evaluated for islet cell composition, vascular density, and endocrine cell proliferation. Single and repeated pimonidazole injections over an 8-hour period yielded accumulation of pimonidazole adducts in the same islets. An average of 30% of all islets was in all cases positively stained for pimonidazole adducts. These islets showed a similar endocrine cell composition as other islets but had lower vascular density and β-cell proliferation. In conclusion, low-oxygenated islets were found to be a stable subpopulation of islets for at least 8 hours. Although they have previously been observed to be less functionally active, their islet cell composition was similar to that of other islets. Consistent with their lower oxygenation, they had fewer blood vessels than other islets. Notably, β-cell regeneration preferentially occurred in better-oxygenated islets.

Authors: Bello Corina , van Rensburg Adriaan , Meineri Massimiliano , Luedi Markus M.
Published: June 2019

Eye drops such as topical β-blockers are widely used to treat glaucoma and other ocular diseases. We provide an overview of ophthalmic solutions, including β-adrenergic receptor antagonists, for anesthesiologists and others involved in perioperative care. We summarize current evidence about systemic effects of topical β-blockers and other commonly used ophthalmic agents such as parasympathomimetic eye drops, carbonic anhydrase inhibitors, nonsteroidal anti-inflammatory drugs (NSAIDs), and emerging products such as combinations of multiple substances. We call for careful preoperative assessment and perioperative management of individuals using eye drops, especially critically ill patients, children, or those undergoing major surgery.

Authors: Oster Andrew S. , Reina Eduardo , Fehr James J. , Moore Robert P. , Cox Thomas E. , George Preeta
Published: June 2019

Although originally described to assist airway management of fetal congenital malformations with life-threatening airway obstruction, the indications for an ex utero intrapartum treatment (EXIT) have expanded to include surgical resection of lesions that are potentially incompatible with life in the absence of uteroplacental circulatory support. We describe the case of an infantile fibrosarcoma (IFS) that presented with fetal hydrops and was successfully managed with an emergency EXIT that necessitated the initiation of a massive fetal blood transfusion both with and without the support of uteroplacental circulation.
Medicaid DSRIP in New Jersey: Trade-offs between Broad Hospital Participation and Safety Net Viability
Authors: Chakravarty Sujoy , Lloyd Kristen , Farnham Jennifer , Brownlee Susan
Published: June 2019

The Delivery System Reform Incentive Payment (DSRIP) program, an increasingly utilized payment strategy to foster population health management by hospitals and outpatient providers, may sometimes generate financial and operational hardships for safety net hospitals (SNHs). The authors utilized a hospital survey and stakeholder interviews to examine impacts of the New Jersey DSRIP program, particularly focusing on its participatory structure that extended eligibility to all hospitals, and specific effects on SNHs. They found that the New Jersey DSRIP fulfilled its primary objective of conditioning receipt of Medicaid supplementary payments on quality and reporting of care by hospitals. It also provided an impetus to ongoing hospital-directed initiatives and introduced new areas of focus, including behavioral health and obesity. However, stakeholders reported that program implementation was not sensitive to specific constraints, priorities, and resource needs of SNHs. Some of the policies relating to outpatient partnerships, reporting of quality metrics, and monitoring low-income populations were perceived to have placed disproportionate burdens on SNHs. Despite appearing to meet its primary goals, the New Jersey DSRIP experience reveals a critical need to be responsive to problems faced by SNHs so as to limit their short-term transition costs and maintain financial viability for serving their patient populations.
Role of ALDH1A1 and HTRA2 expression to CCL2/CCR2 mediated breast cancer cell growth and invasion
Authors: Hu Qingting , Myers Megan , Fang Wei , Yao Min , Brummer Gage , Hawj Justin , Smart Curtis , Berkland Cory , Cheng Nikki
Published: June 2019

Chemokines mediate immune cell trafficking during tissue development, wound healing and infection. The chemokine CCL2 is best known to regulate macrophage recruitment during wound healing, infection and inflammatory diseases. While the importance of CCL2/CCR2 signaling in macrophages during cancer progression is well-documented, we recently showed that CCL2-mediated breast cancer progression depends on CCR2 expression in carcinoma cells. Using 3D Matrigel: Collagen cultures of SUM225 and DCIS.com breast cancer cells, this study characterized the mechanisms of CCL2/CCR2 signaling in cell growth and invasion. SUM225 cells, which expressed lower levels of CCR2 than DCIS.com cells, formed symmetrical spheroids in Matrigel: Collagen, and were not responsive to CCL2 treatment. DCIS.com cells formed asymmetric cell clusters in Matrigel: Collagen. CCL2 treatment increased growth, and decreased expression of E-cadherin and increased TWIST1 expression. CCR2 overexpression in SUM225 cells increased responsiveness to CCL2 treatment, enhancing growth and invasion. These phenotypes corresponded to increased expression of Aldehyde Dehydrogenase 1A1 (ALDH1A1), and decreased expression of the mitochondrial serine protease HTRA2. CCR2 deficiency in DCIS.com cells inhibited CCL2-mediated growth and invasion, corresponding to decreased ALDH1A1 expression and increased HTRA2 expression. ALDH1A1 and HTRA2 expression were modulated in CCR2 deficient and CCR2 overexpressing cell lines. We found that ALDH1A1 and HTRA2 regulates CCR2-mediated breast cancer cell growth and cellular invasion in a CCL2/CCR2 context dependent manner. These data provide novel insight on the mechanisms of chemokine signaling in breast cancer cell growth and invasion, with important implications on targeted therapeutics for anti-cancer treatment.

Published: June 2019

A 50 year old woman from Nepal had clinical features suggestive of meningitis. Cerebrospinal fluid (CSF) analysis was normal except for the presence of cryptococcal antigen. The inclusion of test for Cryptococcus in the CSF helped in making the diagnosis of cryptococcal meningitis in our patient who was apparently immunocompetent. Treatment with liposomal amphotericin B could not be started on time due to financial constraints. The patient had a stroke and further deteriorated. Liposomal amphotericin B is stocked by the government of Nepal for free supply to patients with visceral leishmaniasis, but the policy does not allow the drug to be dispensed for other infections. The family members of our patient acquired the drug within a few days from a government center using their political connections and following administering the treatment the patient improved. This case demonstrates the utility of considering cryptococcal meningitis as a differential diagnosis, and including tests for Cryptococcus when dealing with immunocompetent patients presenting with meningitis. It also demonstrates the effects of the sociopolitical situation on health care delivery in low- and middle-income countries (LMICs) such as Nepal.

Characterization of Coal Samples from Godavari Kani Deposits Using Fourier Transform Infrared Spectroscopy
Authors: B. Manoj , A. Chandrasekharan K. , G. Kunjomana A.
Published: June 2019

Coal is one of the most abundant organic fuels available in India. Understanding the properties of minerals and ash in coal will be helpful in providing a better knowledge of the factors that control their performance in furnaces. The convention tool for the analysis of mineral content is X-ray diffraction (XRD) method. The capability of XRD for quantitative analysis is restricted to the minerals with good crystal structures. For the amorphous and low crystalline minerals, XRD cannot provide accurate quantitative information. At the same time, even for minerals with a good crystal structure, XRD measurement is a time consuming technique. However, studies on minerals have suggested that FTIR spectroscopy is a superior alternative with respect to speed, accuracy and lower cost. FTIR technique has been used widely in the study of coal,minerals,fly ash and rock. Fourier transform infrared (FTIR) spectra of sub bituminous coal samples, collected from a borehole located at Godavari kani deposit, Andhra Pradesh were recorded between 400 and 4000cm-1. A comparative study of mineral content in coke sample imported from China is also performed using FTIR spectroscopy.

Threatened Biodiversity of Sundarban Biosphere Reserve with Reference to Faunal Habitat and Need for Its Preservation
Authors: Chatterjee Rajeshwari
Published: June 2019

The beautiful forests of Sunder bans embracing mysterious tracts of wilderness are located in the lower Ganga delta of Bengal. The mangrove forests and the overall ecosystem in Sunder bans are the ideal habitats for large group of terrestrial, avian and aquatic fauna, starting from Protozoa to Mammals. It contains the richest biodiversity among the inter-tidal forest in the worlds and is the only natural mangrove forest in the world, where the tiger (Panthera tigris tigris L.) resides. The reason for high faunal diversity is the fact that here the ocean and land comes in contact of each other. The succession from ocean to land and to fresh water/ brackish-water through estuaries, change in water salinity from almost nil to high through grades of different concentration; newly formed islands with soft swampy mud to mature old islands with hard saline banks provides fascinating habitat opportunities to various organism. During the last two centuries, these highly productive mangrove ecosystems had been suffering from rapid degradation. If this negligence or ignorance continues in future there will be random exploitation of this natural resource and loss of diverse biota will be unavoidable. A genuine understanding of the interaction of responsible factors should be of paramount interest to the estuarine ecosystem and for prosperity. Recently, it has been established that natural factors along with direct and indirect human interferences have largely changed the biological composition, ecosystem function, productivity, and regeneration and succession patterns within the mangrove ecosystem.

Synthesis and Characterization of Phthalic Acid Complexes with Biologically Active Metal Ions
Authors: Peter S. , Selvakumar M. S.
Published: June 2019

Animal and plants contain carboxylic acids, which are involved in their metabolic reactions. It is also well known that metal ions are involved in their metabolic reactions. So far the complexation of carboxylate ions with metal ions has been extensively studied. Since neutral or acidic medium is existing in most of the biological reactions in animals and plants it is interesting to study the complexation of organic carboxylic acids in neutral medium with biologically active metal ions such as manganese, cobalt, nickel, copper and zinc. Complexes of phthalic acid were prepared in neutral medium and were characterized. In such complexes the carboxylic acid group is not ionised and carbonyloxygen of the carboxylic acids are coordinated to the metal ions. However the microbial study is not the scope of this work.
Applications of the Volume Averaging Theory to Momentum and Heat Transfer within Complex Flow Systems
Authors: Nakayama Akira
Published: June 2019

The volume averaging theory (VAT) developed in the study of porous media is quite powerful in attacking difficult problems associate with momentum and heat transfer in complex fluid flow system, such as heat exchangers, combustors and engine nacelles. Applications of VAT to momentum and heat transfer within complex heat and flow systems are reviewed in this lecture. Such difficulties arise from geometrical complexities and conjugate heat transfer between fluids and solids. In order to overcome the difficulties, the set of the governing equations are integrated over a local control volume to obtain the macroscopic governing equations. The sub-scale (i.e. pore-scale) modeling is carried out to close the set of the equations. Subsequently, the unknown model constants are determined by conducting direct numerical simulations using a structural unit model. Various applications in heat exchangers, composting systems and human bodies are discussed to elucidate the validity of the present procedure.

Published: June 2019

This paper presents the comparison the results of an experimental work with a numerical work keeping the geometry of the test duct and inlet boundary conditions unaltered. The numerical simulation is validated with the experimental results based on the wall y+ approach for different turbulence models suited for this type of geometry. The experimental work is carried out at mass averaged mean velocity of 40m/s with the measurement of total pressure by a pre-calibrated multi-hole pressure probe and the results presented in the form of a pressure contours in 2-D. For validation of the numerical results Standard k-ε, k-ω and Reynolds Stress Model (RSM) are used to solve the closure problem. The turbulence models are investigated in the commercial CFD code of Fluent using y+ value as guidance in selecting the appropriate grid configuration and turbulence model. Based on the wall y+ values for different turbulence models, it is concluded in the present study that the mesh resolving the fully turbulent region is sufficiently accurate in terms of qualitative features and RSM turbulence model predicts the best results while comparing with the experimental results.

Management of Land and Water Resources for Ecological Security
Authors: Rudrappan D.
Published: June 2019

Management of land and water resources has emerged as a vital issue in promoting biodiversity and ecological security programmes. The basic message of ecological security is not of containing development to save ecology but of managing ecology to promote development. What is good for development is equally good for ecology. Developmentalists point out that development not only provides for all-round expansion of the economy but also brings capacity for improving the quality of ecology. Therefore the basic issue is that the wheel of development must move on but it should advance within the supportive capacity of the ecosystem. Any desired development should have the ingredients of efficiency, equity and democracy. When this is done the people tend to take ecology-friendly decisions. The validity of the above ideas is tested through a case study on Palar river basin. Management of Palar river basin against water pollution requires effective monitoring and implementation of protective measures not only for the management of water care but also for the land care as well. In doing so, this study analyses the grave problems posed by tannery effluents and suggest measures for achieving sustainable development, environment and livelihood security.

Visualisation of Collage Grammar to CellWorks: ET0L Mode and Part Sensitive Mode
Authors: Thomas Ann Susa
Published: June 2019

Images are an important aspect of human life as one remembers pictures better than words. Informally, a twodimensional string is called a picture. A two-dimensional language (or picture language) is a set of pictures. Picture generation and analysis has become a widely investigated field in Theoretical Computer Science and in Mathematics. Collage grammars are studied as devices that generate pictures by rewriting based on hyperedge replacement. A cell-work is a finite set of cells where each cell (being a three dimensional entity) is surrounded by one or more faces. This paper focuses on how cell work languages can be captured by collage grammar in ET0L and Part Sensitive modes.

Coherence, Interference and Visibility
Authors: Qureshi Tabish
Published: June 2019

The interference observed for a quanton, traversing more than one path, is believed to characterize its wave nature. Conventionally, the sharpness of interference has been quantified by its visibility or contrast, as defined in optics. Based on this visibility, wave-particle duality relations have been formulated for two-path interference. However, as one generalizes the situation to multi-path interference, it is found that conventional interference visibility is not a good quantifier. A recently introduced measure of quantum coherence has been shown to be a good quantifier of the wave nature. The subject of quantum coherence, in relation to the wave nature of quantons and to interference visibility, is reviewed here. It is argued that coherence can be construed as a more general form of interference visibility, if the visibility is measured in a different manner, and not as contrast.Quanta 2019; 8: 24–35.
Virūpākṣa-vasantotsava-campū of Ahobala or What Can Happen During the Hunting Festival
Authors: Lidia Sudyka
Published: June 2019

Virūpākṣa-vasantotsava-campū describes the nine-night-long Spring Festival, vasantotsava, in the capital of the Vijayanagara kingdom. The text is quite ambiguous in many respects. It is probable that one of its protagonists, a certain Brahmin, a poet by profession, speaks here on behalf of the real author, Ahobala, who most probably lived in the 15th century CE. The present paper will be devoted to the episode connected with the mṛgayotsava or the Hunt Festival, which was a part of vasantotsava celebrations. What will be particularly stressed is the fact that Ahobala’s description of the mṛgayotsava, which takes place in the public sphere connected strongly to kingship, unexpectedly evolves into the experience belonging to a private sphere, namely concerning a personal meeting of a devotee with God. At the same time the poet evoked rich tradition of showing the forest as the place of encounters between representatives of different worlds.
Identification of Essential Proteins Using Induced Stars in Protein–Protein Interaction Networks
Authors: Vogiatzis Chrysafis , Camur Mustafa Can
Published: June 2019

In this work, we propose a novel centrality metric, referred to as star centrality, which incorporates information from the closed neighborhood of a node, rather than solely from the node itself, when calculating its topological importance. More specifically, we focus on degree centrality and show that in the complex protein–protein interaction networks, it is a naive metric that can lead to misclassifying protein importance. For our extension of degree centrality when considering stars, we derive its computational complexity, provide a mathematical formulation, and propose two approximation algorithms that are shown to be efficient in practice. We portray the success of this new metric in protein–protein interaction networks when predicting protein essentiality in several organisms, including the well-studied Saccharomyces cerevisiae, Helicobacter pylori, and Caenorhabditis elegans, where star centrality is shown to significantly outperform other nodal centrality metrics at detecting essential proteins. We also analyze the average and worst-case performance of the two approximation algorithms in practice and show that they are viable options for computing star centrality in very large-scale protein–protein interaction networks, such as the human proteome, where exact methodologies are bound to be time and memory intensive.
O HORROR À VIDA INTERIOR E O ROMANCE FILOSÓFICO A NÁUSEA.
Authors: Pinheiro Rafael De Sousa , Da Silva Bruna Santos
Published: June 2019

O objetivo do presente trabalho consiste em explicitar os fundamentos da crítica de Sartre ao determinismo psicológico e à noção de intimidade, citados pelo filósofo como pertinentes à obra de autores como Proust e Balzac, e apresentar o romance filosófico A náusea como uma proposta alternativa de literatura que estabelece uma descrição compreensiva de como os homens vivem, sem recorrer a determinismos ou à ideia de intimidade. Para tanto, inicialmente, busca-se apontar a teoria fenomenológica da consciência desenvolvida por Sartre em A transcendência do ego, e como o modo de aparição do “Eu” enquanto um objeto correlato de uma intenção reflexiva, é constituído como polo passivo e inerte de estados, de tal modo que a consciência, espontaneidade impessoal, permanece inafetável, argumento que fundamenta a crítica ao determinismo psicológico. Em seguida, a partir do texto Uma ideia fundamental da fenomenologia de Husserl: A intencionalidade, desenvolve-se a crítica de Sartre à noção de intimidade, presente, por exemplo, na obra de Proust. Por fim, apresentam-se as características do romance A náusea que a constituem como uma proposta alternativa de literatura, uma possibilidade compreensiva da realidade humana livre de pressupostos deterministas e da noção de intimidade.

Authors: Kumar Meenakshi , Savage Grazielle C Mattos , Aukett James W , Gallagher Jennifer E
Published: June 2019

The aim of this article is to encourage general dental practitioners (GDPs) to obtain feedback from patients on a regular basis and act on it. This article will familiarize clinicians with the current concepts of patient experience, patient satisfaction and patient reported outcome measures. It will explore the reasons why dentists should engage in seeking patients' opinions and will shed light on some of the validated questionnaires which are in use in the UK and internationally. Aspects of care considered important by patients are explored and important questions which should be included when developing individual practice questionnaires are highlighted. We build on previous Dental Update articles on this subject by taking the reader through the concept of the Plan Do Study Act (PDSA) cycle and how this can be utilized.

This paper will not only allow dentists to improve and grow their practices, but also contribute towards clinical governance and the ethos of patient-centred care.

CPD/Clinical Relevance: This article enables dental professionals to appreciate the importance of obtaining patient feedback on key issues relating to their dental care. It suggests ways in which dental teams could engage in obtaining patient feedback and act upon it to develop the quality of services.
