“To Put Others Before Yourself”: Volunteerism and Mental Health in US Veterans’ Projects
Authors: Usbeck Frank
Published: November 2018

The post-9/11 wars produced a new generation of US veterans. As the military campaigns dragged on over extended periods, public discourse on the wars refueled ongoing discussions from the Vietnam era about veterans’ social and psychological wellbeing. The public increasingly voiced concerns about psychological injuries such as posttraumatic stress, veterans’ postwar reintegration struggles, and suicides. This article will discuss two NGOs organized by and for veterans to analyze how their activism responds to the sense of social crisis prevalent in these public debates on veterans’ affairs. It will present the projects’ online self-representation and their documentation in activist scholarship and journalism to carve out how civic engagement in veterans’ affairs challenges the traditional myth of American individualism to promote volunteerism and community service as vehicles for reintegration, promoting – and enacting – the civil-military social contract.
Liminality in Janice Galloway’s Short Fiction
Authors: Sacido-Romero Jorge
Published: November 2018

One of the most salient developments in recent short story criticism focuses on the genre’s connection with liminality. Both short fiction’s suitability to convey the liminal and liminality as a defining feature of the short story are at stake. The short fiction of contemporary author Janice Galloway is a good example of this. After a brief introduction to the concept of liminality, I discuss one story from each of Galloway’s collections of short fiction: “Frostbite” is the story of how a young music student crosses an existential boundary and leaves behind disabling expectations and fears; “jellyfish” features a divorced woman undergoing a liminal moment in her experience of motherhood, whereas the woman in a homeless couple in “a night in” narrates her experience as a privileged witness to ontological liminality affecting both space and language.
MICROENCAPSULATION OF BERGAMOT PEEL ESSENTIAL OIL WITH GUM ARABIC AND MALTODEXTRIN BLENDS: STABILITY AND RELEASE CHARACTERISTICS OF THE ESSENTIAL OIL COMPOUNDS
Authors: ÖZDEMİR Kübra Sultan , AZARABADİ Negin , Topuz Ayhan
Published: November 2018

Bergamot peel essential oil is a
high value product which can be used in food, beverage, confectionary, and
cosmetic industries. Bergamot essential oil has high volatility, so it could be
easily affected by environmental factors so it should be protected with further
techniques to increase its shelf-life. The aim of this study was to examine the
effect of different wall material compositions on the product yield,
encapsulation efficiency, physical and chemical properties of encapsulated oil
powders. For this purpose, bergamot essential oil was encapsulated with gum
arabic and maltodextrin (DE 12) in varying concentrations (100:0, 0:100, 25:75,
75:25, 40:60, 60:40). Then, physical and chemical (terpenoid composition)
characteristics of microcapsules were evaluated. The microcapsules were stored
at 25°C for 20 days and the content and stability of main aroma compounds were
determined after storage. The encapsulation yield was increased when the
maltodextrin ratio was increased however, gum arabic provided greater
protection of essential oil composition.

A RESEARCH ON DETERMINATION OF THE RELATIONSHIP BETWEEN ORGANIZATIONAL SUPPORT AND ORGANIZATIONAL CITIZENSHIP BEHAVIOR
Authors: GÜVEN Bülent
Published: November 2018

Organizational support has become an increasingly important issue for organizations to become more productive and reaching targets. Members of the organization provide a significant contribution to the extent they feel they are supported by their organizations. However, an organization member who thinks that organizational support has been provided is one step ahead of their work. Organizational citizenship behavior (OCB) covers a number of factors based on voluntary but non-compulsory behaviors and attitudes of the organization's members. Whether the organizational support that employees perceive affects organizational citizenship behavior or not is subject worth to study. This study on the relationship between organizational citizenship behavior with its dimensions and perceived organizational support was revealed by a survey among glass factory employees operating in Ankara. In the study conducted, it was concluded that there is a positive relationship between organizational citizenship behaviors and perceived organizational support. In this context, as the perceptions of organizational support increase, the exhibitions of organizational citizenship behaviors towards the organization and individual also increase.

TESTING MEDIATING EFFECT OF INDIVIDUAL EXCHANGE IDEOLOGY ON DISTRIBUTIVE JUSTICE AND WORK ENGAGEMENT RELATIONSHIP IN A COLLECTIVIST SOCIETY
Authors: KILIÇ AKINCI Sevcan
Published: November 2018

This study aims to test the Social Exchange Theory in a collectivist society and extends it by examining the link between distributive justice (DJ) and work engagement (WE). Specifically, individual exchange ideology (IEI) is integrated into the relationship, and it establishes if exchange ideology mediates between the relationships. The study was conducted on a large sample (499) of Turkish blue and white-collar employees from business units of 15 independent companies; 10 different industry types and data was analysed with Structural Equation Modelling. The findings of this research supported the previous findings about DJ’s positive relationship with WE. Secondly, findings showed that IEI acted as a mediator between DJ and WE, and it mediated 24% of the effect of DJ’s on WE. Results revealed that employees reciprocated perceived justice (DJ in our case) by engaging themselves more in their work, to meet organisational goals, but this increases with the effect of individual exchange ideology; and therefore, supported the applicability of Social Exchange Theory in a collectivist society, namely in a Turkish context.

Authors: BASHEER Muhammad Farhan , IMRAN Muhammad , HAMID Siti Norasyikin Abdul , AZIZ Azelin
Published: November 2018

Decision making is one of the primary functions of management. Making strategic decisions are important to achieve organisational efficiency and effectiveness. In the selection of projects, it is necessary for organisations to prioritise their projects due to limited resources. Therefore, the selection of projects that bring value and substantial impact on the organisation is very important to ensure that they can compete in the dynamic external environment and meet the goals and objectives. From the case study, the result suggests that the Analytical Hierarchy Process (AHP) method can contribute significantly to the identification of sources that need further clarification of attributes and criteria and at the same time it can provide a systematic analytical tool in making a group decision. This method allows the organisation to prioritize its projects based on certain criteria as it is a quantitative decision support tool. In conclusion, AHP is the best and efficient method for decision makers to consider all facts, weigh the pluses and minuses, reach, reevaluate and communicate their decisions.
RETHINKING WORKFORCE DIVERSITY RESEARCH THROUGH CRITICAL PERSPECTIVES: EMERGING PATTERNS AND RESEARCH AGENDA
Authors: AYDIN Erhan , ÖZEREN Emir
Published: November 2018

This paper aims at highlighting the theoretical development of diversity management by providing an integrated understanding of how diversity management has made progress and evolved in organisations. The current article adopts a conceptual and critical review to demonstrate the changes and shifts in diversity management research. This study reveals that there are four stages of workforce diversity within the business and management field. These stages are equal employment opportunity/affirmative action, valuing differences, diversity management and global diversity management. Each stage is discussed in greater details within the article. This study contributes to the broader diversity management literature in three main ways: firstly, by shedding some light on the conceptual clarity of the diversity notion itself; secondly, by foregrounding the holistic view of diversity management; thirdly, by reflecting the recent developments in diversity research. The review consistently points to the fact that the current literature on diversity management has been predominantly shaped by a mainstream managerial discourse and neoliberal logic which has mostly a discrimination focus rather than an inclusiveness perspective. The paper also suggests that further research is required on workforce diversity particularly with an emic, an intersectional, a contextual and a relational approach rather than reproducing the existing knowledge by an etic framing of diversity from an instrumental point of view that dominates the extant literature.

Authors: Mohamad Adam , Ibrahim Rohaida , Mohd Rajet Khairul Azhar , Mohamad Irfan , Aman Anura
Published: November 2018

Hypernasality which is a rare symptom commonly occurs as a consequence of velopharyngeal insufficiency (VPI). VPI usually manifested as nasal air emission and hypernasal resonance during speech. The cause can be divided into congenital, neuromuscular disorder, and surgical complication. Congenital cause of VPI includes cleft palate, nasal septum malformation such as vomer agenesis, submucous cleft palate, and velar dysplasia, while neuromuscular VPI can be due to cerebral palsy or cerebrovascular accident. The surgical cause of VPI could be due to adenoidectomy and scarring of the velum post palatoplasty in cleft palate repair. We present a 17-year-old man who was diagnosed with congenital left nasolacrimal duct obstruction referred to us for left endoscopic dacryocystorhinostomy in which during nasoendoscopic examination revealed the absence of vomer.

Published: November 2018

Bivalve molluscs are sold without any sanitary control in Costa Rica, which represents a public health risk dueto the possible accumulation of pathogenic bacteria. Small scale bacterial depuration treatments were preliminarilyevaluated on Crassostrea gigas and Anadara spp. from the Gulf of Nicoya, Costa Rica, through the useof a recirculating system with UV irradiation. The levels of Escherichia coli in the water were determined usingthe MPN method. The MPN of E. coli and the presence of Salmonella spp., Vibrio parahaemolyticus and V. cholerae were determined in molluscs. Results confirm the effectiveness of the E. coli depuration system designin C. gigas and Anadara spp. The MPN of E. coli in the molluscs was reduced between 79% and 100% after 24h. None of the other types of bacteria were found in the samples analyzed. This is the first C. gigas depurationstudy in Costa Rica and the first report concerning UV depuration for bacterial indicators of fecal contaminationin Anadara spp. This research serves as a basis for the implementation and improvement of mollusc purification conditions in the country. It is recommended to monitor extraction and harvesting areas, as well as to implement the depuration of bivalve molluscs so that traditional producers can offer an innocuous product with added value.Los moluscos bivalvos son comercializados sin ningún control sanitario en Costa Rica; por tanto, representan un riesgo para la salud pública, debido a que pueden acumular bacterias patógenas.

Authors: Duffine Gilman Abigail , Volpe Stella Lucia
Published: November 2018

La obesidad infantil es una preocupación en materia de salud pública que amenaza la salud y el bienestar de los niños en todo el mundo y que se relaciona con varias condiciones crónicas de salud en ese grupo. Aunque el equilibrio energético positivo conlleve a un exceso de peso corporal en los niños, hay varios factores que influyen en su estado de peso. El consumo de alimentos y la actividad física contribuyen en gran medida al equilibrio energético de los niños. La salud mental también se relaciona con su estado de peso y actividad física. Además, la raza y el origen étnico, la estructura familiar, así como el ambiente construido contribuyen a la cantidad de actividad física que practican los niños. Uno de los objetivos de esta revisión es resumir la conexión entre la actividad física y el estado de peso en los niños y resaltar los factores clave que influyen en esta relación, tales como la salud mental y la raza, el origen étnico, la estructura familiar y el ambiente construido. Otro objetivo es resaltar las intervenciones y las políticas que pueden influir en la relación entre la actividad física y el estado de peso en los niños. Las políticas que influyen en el entorno pueden mejorar la accesibilidad a actividades físicas por parte de los niños y afectar la seguridad, la densidad de los supermercados y las instalaciones comerciales de actividad física disponibles en los vecindarios, y el suministro de oportunidades estructuradas de actividad física para los niños. Las políticas que influyen en el entorno escolar también brindan oportunidades para facilitar la actividad física adicional en los estudiantes. Por lo tanto, el propósito general de esta revisión es estudiar los muchos factores que influyen en el estado de peso de los niños y proporcionar ideas para futuras investigaciones.

Published: November 2018

For elderly people that are living alone in their homes there is a need to permanently monitor them. One of this aspect consist in knowing their indoor position and motion behavioural status, in real time. One possibility for indoor positioning of an user consists in understanding the images provided by supervising cameras. In this case the main aspect is represented by recognition of objects from these images. Thus, object recognition plays an essential part in understanding the environment and adding meaning to it. This paper presents a method for indoor localisation based on identifying the user’s context. The user’s context is computed based on object recognition and using a probabilistic ontology. The key element is represented by the probabilistic ontology that describes objects, scenes and relations between them. This ontology contains probabilistic relations that are learned using a large database. Results show that given a set of object detectors with high detection rate and low false positive rate, the system can recognize the user’s context with high accuracy.

Even in its infancy, the internet of things (IoT) has enticed most of the modern industrial areas like smart cities, automobiles, medical technology. Since IoT connects everything together, it is vulnerable to a variety of devastating intrusion attacks. Being the internet of different devices makes it easy for attackers to launch their attacks. Thus, to combat all these attacks, an attack analysis is presented in this article using the basic principles of Artificial Neural Networks. Internet packet traces are used to train to the supervised ANN (Multilevel Perceptron) and evaluated after the training to decline the DDoS Attacks. This research article mainly focuses on the categorization of traffic patterns into legitimate traffic and attack traffic patterns in IoT network. The ANN processes are evaluated and tested in a simulated IoT network. The experimental results show a greater accuracy in detection of various DDoS attacks.
Multi-Objective Tabu Search to Balance Multihoming Loads in Heterogeneous Wireless Networks
Authors: Huertas Jorge A. , Donoso Yezid
Published: November 2018

The advantages of the increasing usage of mobile devices that operate under the multihoming scheme are changing the communications world drastically. Therefore, next generation networks operators have the challenging task to distribute connections of mobile devices efficiently over their access networks, creating a big heterogeneous wireless network for telecommunications. We present a mixed integerlinear programming (MILP) model to balance the load of multiple services over wireless networks taking into account three key indicators: connection loads of access networks, connection costs, and battery consumption of connections. To solve the multi-objective problem, we propose a multi-objective Tabu Search procedure that is capable to find non-supported solutions in the online efficient set. To test the performance of our multi-objective Tabu Search, we tested it over four instances of the literature. In the first instance, a small instance, our procedure finds the true efficient set of solutions. For the other three instances, large instances with over a thousand mobile devices, our procedure finds good online efficient sets of solutions in less than 30 seconds. Finally, using appropriate multi-objective metrics, we compare the results of our multi-objective Tabu Search against the results of a state of the art multi-objective genetic algorithm in the literature for the same problem, outperforming the genetic algorithm in every instance tested.

Published: November 2018

Background

Interventions aimed at improving access to timely cancer care for patients in low- and middle-income countries (LMIC) are urgently needed. We aimed to evaluate a patient navigation (PN) program to reduce referral time to cancer centers for underserved patients with a suspicion or diagnosis of cancer at a public general hospital in Mexico City.

Materials and Methods

From January 2016 to March 2017, consecutive patients aged >18 years with a suspicion or diagnosis of cancer seen at Ajusco Medio General Hospital in Mexico City who required referral to a specialized center for diagnosis or treatment were enrolled. A patient navigator assisted patients with scheduling, completing paperwork, obtaining results in a timely manner, transportation, and addressing other barriers to care. The primary outcome was the proportion of patients who obtained a specialized consultation at a cancer center within the first 3 months after enrollment.

Results

Seventy patients (median age 54, range 19–85) participated in this study. Ninety-six percent (n = 67) identified >1 barrier to cancer care access. The most commonly reported barriers to health care access were financial burden (n = 50) and fear (n = 37). Median time to referral was 7 days (range 0–49), and time to specialist appointment was 27 days (range 1–97). Ninety-one percent of patients successfully obtained appointments at cancer centers in <3 months.

Conclusion

Implementing PN in LMIC is feasible, and may lead to shortened referral times for specialized cancer care by helping overcome barriers to health care access among underserved patients.

Implications for Practice

A patient navigation program for patients with suspicion or diagnosis of cancer in a second-level hospital was feasible and acceptable. It reduced patient-reported barriers, and referral time to specialized appointments and treatment initiation were within international recommended limits. Patient navigation may improve access to care for underserved patients in developing countries.
Propuesta de evaluación para asignar tentativamente riesgo de extinción (ETRE): el caso de Peltogyne mexicana (Leguminosae)
Authors: Montero-Castro Juan Carlos , Zuñiga-Zuñiga José Antonio , Sáenz-Romero Cuauhtémoc , Sánchez-Vargas Nahum Modesto
Published: November 2018

Antecedentes: El ritmo de las estimaciones de riesgo de extinción es lento en relación con la magnitud del problema. En el caso de las plantas se han evaluado el 6 % de las especies. Por otro lado, se ha determinado que la extensión del área de distribución es un buen predictor del riesgo de extinción.Preguntas: ¿Se puede agilizar la estimación de riesgo de extinción de las especies vegetales? ¿Estimaciones de riesgo tomando en cuenta sólo el área de distribución, pueden convergir con estimaciones de métodos ya establecidos?Taxon: Peltogyne mexicana Sitio de estudio: Guerrero, MéxicoMétodos: Se implementó la Evaluación para Asignar Tentativamente Riesgo de Extinción (ETRE) comparando el área de ocupación (AOO) del árbol tropical maderable Peltogyne mexicana contra el AOO de otras leguminosas arbóreas con estatus de riesgo de extinción ya establecidos. Se implementó el Método de Evaluación de Especies en Riesgo (MER) y se compararon los resultados.Resultados: Con la implementación de la ETRE se determinó que el árbol tropical maderable Peltogyne mexicana se encuentra en peligro de extinción, lo cual se confirma con la implementación del MER.Discusión: La idoneidad de la ETRE se basa en que varios predictores del riesgo de extinción están supeditados al tamaño del área de distribución y a que la estimación de ésta última es ampliamente aceptada por medio del AOO. La ETRE es un procedimiento objetivo y fácilmente replicable, que se puede implementar previamente a evaluaciones más escrupulosas, como el MER. Se proponen acciones para evitar la pérdida de Peltogyne mexicana .
Localización de satélites y cromosomas NOR para la interpretación del cariotipo de Sesbania virgata (Papilionoideae, Sesbanieae) de dos poblaciones americanas
Authors: Tapia-Pastrana Fernando , Tapia-Aguirre Fernando
Published: November 2018

Antecedentes: Los estudios citogenéticos en el género Sesbania muestran desacuerdo entre los investigadores sobre el número preciso y posición de las constricciones secundarias y satélites, así como su relación con la organización del nucleolo. La carencia de esta información dificulta la realización de estudios de citogenética comparada y evolución cromosómica confiables en el género.Preguntas: ¿Dónde se ubican las constricciones secundarias y satélites en los cromosomas de Sesbania virgata ? ¿Estas regiones participan activamente en la organización nucleolar?Especie en estudio: Sesbania virgata (Cav.) Pers.Sitio y año de estudio: Municipio de Tlacotalpan, México y Provincia de Salta, Argentina, 2016.Métodos: Se aplicó una técnica de extendido en superficie y secado al aire para obtener cromosomas en prometafase y metafase típica a partir de meristemos radiculares.Resultados: Cada población exhibió un cariotipo diferente y solo dos constricciones secundarias asociadas a macrosatélites en los brazos cortos del par cromosómico más pequeño y no en brazos largos como fue sugerido por otros autores. La inclusión de las constricciones secundarias y satélites en el nucleolo de células en prometafase permitió corroborar su participación activa en la formación de éste. Esta información se utilizó para reevaluar la posición de las regiones del organizador nucleolar “NOR”.Conclusiones: Nuestros resultados concuerdan con el punto de vista predominante sobre la ubicación de los “NOR” en los brazos cortos de especies vegetales, particularmente en leguminosas. Además, dado que las poblaciones bajo estudio se encuentran geográficamente aisladas sugerimos que se favorece un proceso activo de especiación manifestado en los dos citotipos encontrados cuyas diferencias se atribuyen a cambios en la proporción de brazos de los cromosomas satelitales.

Published: November 2018

Background: Amaranth is a plant of interest in farming due to its ability to adapt into arid and semi-arid climates. Biological activity by microorganisms in rhizosphere determines plant performance and quality.Hypothesis: The enzymatic activity is different in two types of soil, rhizosheath soil (adhered by roots) and loose soil (non-adhered by roots), in four cropping periods of amaranth.Species study: Amaranthus hypochondriacus L.Methods: Parameters of soil organic matter and several enzyme activities in the amaranth rhizosphere were assessed. Two types of soil, rhizosheath soil and loose soil, and four cropping periods were compared. Thirty-seven culturable bacterial isolates obtained from rhizosheath soil were molecularly identified.Results: Rhizosheath soil had higher content of carbon and total nitrogen compared with loose soil; however, potential enzyme activity in both soil types was similar. Dehydrogenase and acid phosphatase activities were very sensitive to the crops phenological stages. Acid and alkaline phosphatases, cellulase and protease activities correlated to changes in soil moisture. The greatest diversity of culturable bacteria was found during the flowering stage.Conclusions: In the rhizosphere of A. hypochondriacus grown in a pumiceous sandy soil, enzymatic activities in the rhizosheath and loose soils were similar, which must be considered a unique rhizosphere environment. Dehydrogenase and acid phosphatase activities were highly sensitive to changes in the crop phenology. The behavior of phosphatases and dehydrogenase activities suggests an increased dynamic soil organic matter (SOM) during the post-harvest period. In the amaranth rhizosphere, native culturable bacteria are involved in the breakdown of SOM.

El objetivo al que aspiran todos los diccionarios no es otro que ofrecer una visión objetiva de la realidad. El lexicógrafo ha de enfrentarse a la difícil tarea de dejar a un lado sus creencias y opiniones y centrarse en el aspecto puramente lingüístico.Tras 21 ediciones, la Academia decidió iniciar un proceso de «depuración ideológica» en la edición de 2001 con el propósito de reducir el sesgo ideológico que destilaban ciertas definiciones. Sin embargo, el proceso de revisión parece no haberse llevado a cabo de una manera sistemática, pues aún persisten algunas definiciones en las que la presencia del autor se deja ver claramente.El propósito del presente estudio se centra en la comparación entre algunas de las definiciones presentes en las ediciones de 2001 y 2014 del diccionario académico para constatar si las labores de corrección han dado su fruto y, por tanto, si el autor del diccionario ha decidido enfundarse al fin el guante de la objetividad o, por el contrario, continúa dejando su huella entre las páginas del diccionario académico.
Nuevas aportaciones a la lexicografía del anglicismo: una mirada al léxico erótico
Authors: Rodríguez González Félix
Published: November 2018

El trabajo examina la enorme influencia del inglés registrada en el ámbito del sexo y el erotismo en las últimas décadas, especialmente a partir de la Transición, al compás de los cambios sociales y políticos y los nuevos aires de libertad que han tenido lugar en España. En particular, pasa revista a los anglicismos léxicos y calcos que han ido poblando los distintos campos semánticos que conforman esta esfera del lenguaje (artilugios y juegos sexuales, vestimenta erótica, nuevas identidades sexuales, etc.).
La dignidad de la persona humana, principio conceptual del accionar judicial en Colombia y en Alemania
Authors: Cruz Mahecha Diego Enrique
Published: November 2018

La valoración de algunos de los pronunciamientos del Tribunal Constitucional Alemán permite vislumbrar la forma en que esa corporación judicial evidencia el papel que le asiste a la dignidad humana, por cuanto entiende queesta funge como piedra angular del ordenamiento. Al concebir el derecho bajo estos criterios funcionales, es claro que la posición jurisprudencial sobre el particular se orienta hacia el establecimiento de un criterio garantista, con el que se ha de vivificar el contenido de los derechos que emanan de la positivización de la dignidad humana, esta es la posición argumentativa contenida en el presente escrito, a través de la cual se invita al lector a la reflexión sobre estos criterios jurisprudenciales que en muchos casos tienen su par en la jurisprudencia colombiana.

Son yıllarda yenilebilir film
ve kaplamaların kullanılması ile peynir üretim miktarını ve kalitesini artırmak
için yapılan çalışmalar hızla devam etmektedir. Bu yöntemin esası özellikle
peynir kalitesini artırarak daha güvenilir bir gıda üretimini sağlamaktadır.
Ardahan ilinde hayvancılık çok fazla yapılmasına rağmen güncel gelişmelerden ve
tekniklerden yeterince yararlanılmamaktadır. Türkiye’nin doğu ili olan Ardahan’da
peynir randımanını artırmak amacıyla kullanılan geleneksel metotların, yeni
metotlarla karşılaştırılmasının yapılması ve geleneksel metotların
uygulanmasının sonucu olarak ortaya çıkan kayıpların saptanması önemlidir. Bu
derlemede uygulanacak tekniklerin kaliteli süt ve ürünlerinin üretilmesini
sağlayacağı ve böylece Ardahan ekonomisine daha fazla katkı sağlanabileceği
vurgulanmıştır.﻿
Pütürge Metamorfitlerindeki Amfibolit Fasiyesi Granatların Mineralojisi ve Sm-Nd İzotop Jeokimyası
Authors: KILIÇ Ayşe Didem , KAYA Hilal
Published: November 2018

Toros Orojenik kuşağı üzerinde, Malatya-Pütürge
ilçesindeki metamorfitlere ait granatlar, granat mikaşistler ve granat
stavrolit/silimanit mika şistler içerisinden seçilmiştir. Elektro-mikropirob
verilerinden (EPMA) Alm81Prp8Grs7Spess5 bileşimli olduğu belirlenen bu
granatların türü, almandin’dir. Almandin türü bu granatlarda, kısmen bazı
tanelerinde ters zonlanma belirlenmiştir. Bu zonlanmanın varlığı ve granatı
çevreleyen silimanit ve biyotitler; katyon alış-veriş reaksiyonlarının granat
kimyası üzerinde belirleyici olduğunu işaret eder. Kayaçların mineral
parajenezlerinden ve granat-biyotit jeotermometresi hesaplamalarından elde
edilen sonuçlardan, metamorfizma sıcaklığının 600°C aştığı ve metamorfik
masifin bölgesel tektonikten etkilenmesi nedeniyle de basınç gölgesi,
kapanımların yönlenmesi, belirgin şistozite ve ötelenmiş foliasyon gibi yapılarının
geliştiği görülmüştür. Metamorfitler, amfibolit fasiyesinde ilerleyen ve
yeşilşist fasiyesinde gerilen metamorfizma gösterirken, metamorfizmada
bölgenin aktif tektoniğinin önemli 
etkisi vardır. Bunun önemli işaretlerinden biri, granatın çekirdeği ve
kenarından alınan Sm-Nd mineral yaş verisi (81.53±0.10 ve 82.18±0.17)
arasındaki farkın azlığıdır. Bu özellik, aynı zamanda masifin ani yükselmesi
sonucunda gelişen soğumanın mineraller üzerindeki etkisinin de kanıtıdır.

Do stem cell divisions significantly contribute to cancer development?
Authors: Sandarage Ryan , Chitpin Justin G.
Published: November 2018

Cancer is caused by uncontrolled cellular growth, yet some cancer cells may have greater roles in sustaining tumour proliferation and overcoming conventional cancer treatments. The origins of these cancer stem cells, as they are hypothesized, is widely contested. The current opinion points to extrinsic factors such as smoking, diet and sedentary lifestyle to be the primary inducer of cancer stem cells. This dogma was challenged in 2015 when Tomasetti and Vogelstein postulated that two-thirds of the variation in cancer risk could be explained by random mutations arising during DNA replication in healthy stem cells. Their "bad luck" hypothesis sparked fierce debate and controversy in the scientific community. In this point-counterpoint article, we discuss the random mutation cancer stem cell model and its implications for guiding public health through primary and secondary cancer prevention.
Chromosomal instability and aneuploidy: a conundrum in cancer evolution
Authors: Ali Jasmin
Published: November 2018

Chromosomal instability (CIN), defined as an increased rate of gain or loss of whole chromosomes, leads to aneuploid cells, which are cells that display an abnormal number of chromosomes. Both CIN and aneuploidy are hallmarks of cancer, yet the underlying mechanisms of CIN and aneuploidy and their impact on tumourigenesis have remained poorly defined. Although multiple mechanisms have been proposed to explain the role of CIN and aneuploidy in tumourigenesis, this review focuses on three principal pathways leading to CIN: spindle assembly checkpoint defects, merotelic attachments, and cohesion defects. Here, we provide a brief overview of the current understanding of the roles of these mechanisms in CIN and aneuploidy. We also present emerging evidence that contradicts the importance of certain mechanisms in cancer evolution. A clearer understanding of these fundamental pathways could prove to be helpful in developing effective cancer therapies.
An observational study to evaluate improved graft acceptance and viability after single dressing on 15th postoperative day in cases of split thickness skin graft (STSG)
Authors: Naik Narendra G. , Karandikar Sangram
Published: November 2018

Background: After split thickness skin graft (STSG), it’s a routine practice to change recipient site dressing on 5th post-operative day and frequent dressing thereafter. The repeated change of recipient site dressing may interfere in graft acceptance. It’s also an effort to evaluate cost-effectiveness and graft acceptance after single dressing of recipient site at the end of 2 weeks.Methods: In the study group, 120 patients were operated for STSG. The recipient site dressing was done on 15th post-operative day. Observations were made regarding presence of residual ulcer at the recipient site. The results were compared with rate of residual ulcers at the recipient site in control group. The control group was comprised of 134 patients of STSG operated by the same surgeon in the previous year. Their dressing of recipient site was first changed on 5th post-operative day and multiple times thereafter. The results in both the groups were correlated with co-morbidities affecting wound healing.Results: The rate of residual ulcer at recipient site in both the groups was comparable with better cosmetic result and cost-effectiveness associated with the study group. In both the groups, common co-morbid factors were observed to be responsible for residual ulcers at the recipient site.Conclusions: After appropriate preparation of recipient site and in absence of co-morbid factors, the single 1st dressing of recipient site on 15th post-operative day gives better cosmetic outcome. This is also cost-effective as compared to the traditional practice of frequent multiple change of recipient site dressing.
Spigelian hernia: a rare abdominal hernia
Authors: Hussain Sajid , Jawed Shakil , Parveen Zamurrad , Bakhteyar Md. Asjad Karim
Published: November 2018

Spigelian hernia is a rare variety of abdominal wall hernia occurring through the spigelian fascia which is composed of the aponeurotic layer between rectus muscle medially and semilunar line laterally. Generally it is difficult to diagnose because of their location and non specific symptoms. Diagnosis is aided by ultrasonography and Computerized Tomography. Once the diagnosis is confirmed, it is repaired surgically as risk of incarceration is high. We reported this interesting case of spigelian hernia with associated port site hernia in a 53 year old female patient from Arwal district, Bihar who presented with occasional lower abdominal pain. The hernia was reduced and defect was repaired. Her recovery was uneventful.
