Limited Mitochondrial Capacity of Visceral Versus Subcutaneous White Adipocytes in Male C57BL/6N Mice
Authors: Schöttl Theresa , Kappler Lisa , Braun Katharina , Fromme Tobias , Klingenspor Martin
Published: December 2014

Accumulation of visceral fat is associated with metabolic risk whereas excessive amounts of peripheral fat are considered less problematic. At the same time, altered white adipocyte mitochondrial bioenergetics has been implicated in the pathogenesis of insulin resistance and type 2 diabetes. We therefore investigated whether the metabolic risk of visceral vs peripheral fat coincides with a difference in mitochondrial capacity of white adipocytes. We assessed bioenergetic parameters of subcutaneous inguinal and visceral epididymal white adipocytes from male C57BL/6N mice employing a comprehensive respirometry setup of intact and permeabilized adipocytes as well as isolated mitochondria. Inguinal adipocytes clearly featured a higher respiratory capacity attributable to increased mitochondrial respiratory chain content compared with epididymal adipocytes. The lower capacity of mitochondria from epididymal adipocytes was accompanied by an increased generation of reactive oxygen species per oxygen consumed. Feeding a high-fat diet (HFD) for 1 week reduced white adipocyte mitochondrial capacity, with stronger effects in epididymal when compared with inguinal adipocytes. This was accompanied by impaired body glucose homeostasis. Therefore, the limited bioenergetic performance combined with the proportionally higher generation of reactive oxygen species of visceral adipocytes could be seen as a candidate mechanism mediating the elevated metabolic risk associated with this fat depot.

Manifested in the form of impact on a salary level the external effect of higher
education dissemination has been investigated in this work. Econometric
models are constructed with the use of Russia regions’ statistics. Manifestation
of higher education distribution’s external effect in the form of general salary
level increase and salary increase of persons who don´t have the higher
education has been established. In the period 2000–2010 in the Russian
economy the spread of higher education among the employed population by
14.9 % determined the salary level of persons who did not have higher
education. The spread of higher education among the employed population in
conjunction with the capital-labor ratio by 80.5% determined in the Russian
economy the salary level of persons who did not have higher education.
Advantages and Disadvantages of Contemporary Methods for Evaluation of Efficiency of Investment in Intellectual Property Items
Authors: Левкина  , Levkina Nataliya
Published: December 2014

Contemporary methods of investment projects’ efficiency evaluation are based

on such fundamental finance theories as J. Williams’ theory of discounted cash

flows, investment portfolio management, pricing model for financial assets and

the theory of options. All these theories were originally intended for analysis of

investment in securities.

This paper provides an overview of contemporary methods for evaluation of

efficiency of investment projects connected with acquisition, development and

use of intellectual property items in the frames of traditional classification,

according to which they are commonly divided into three groups: financial,

probabilistic and qualitative.

As all financial, probabilistic and qualitative methods for evaluation of efficiency

of investment in intellectual property items have their advantages and

disadvantages it is recommended to use these methods’ rational combination in

order to choose the optimal investment variant.

Las marcas de la paideia en Homero. Banquete, palabra e identidad: los tópicos de las lecciones
Authors: Colombani Maria Cecilia
Published: December 2014

El proyecto del presente trabajo consiste en pensar la dimensión educativa en Homero. Entendemos que tanto en Ilíada como en Odisea aparecen elementos suficientes para poder ubicar a Homero en el lugar de un educador, tarea que la crítica ha realizado, sobre todo en torno a la educación aristocrática de la que Ilíada parece ser un ejemplo emblemático. Nuestro intento es ubicarnos en un plano nítidamente antropológico para ver cómo la paideia transita un andarivel que sitúa las relaciones entre los hombres y los dioses y los hombres entre sí como planos diferenciados que dan cuenta de un modelo de instalación ético-antropológica que constituye el núcleo mismo de la paideia como empresa moral. Se trata entonces de rastrear una determinada constitución subjetiva que incluye dos topoi de consideración, las relaciones entre mortales e Inmortales, como forma de habilitar el espacio que los hombres habrán de ocupar, y las relaciones intersubjetivas, como modo de territorializar los vínculos en el universo personal.http://dx.doi.org/10.14195/2183-1718_66_1

Soberana del Hades. Perséfone en la epigrafía funeraria y en las láminas áureas
Authors: González González Marta
Published: December 2014

En este trabajo se plantea el estudio de la diosa Perséfone en la documentación epigráfica funeraria y en las famosas lamellae aureae. Cronológicamente, el análisis se limita al s. IV a.C., momento en el que la diosa aparece por primera vez en los epitafios y momento también al que pertenecen las primeras lamellae documentadas.  En estos textos la figura de la Soberana del Más Allá es fundamental y supera los límites de sus papeles míticos habituales, tanto el de doncella raptada, hija de Deméter, como el de esposa de Hades. También se propone una comparación con la documentación iconográfica, un poco anterior, constituida por los pínakes de Locris.http://dx.doi.org/10.14195/2183-1718_66_17

Effect of Gender on Language Performance of American Speakers, Russian Native Speakers, and American L2 Learners of Russian in a Complaint Situation
Authors: Gallaher Beata
Published: December 2014

The present study investigates linguistic choices and strategy selection of American speakers of English, Russian native speakers, and American L2 learners of Russian in their complaints by exploring the interaction of social factors and gender. The data was elicited through an open-ended discourse completion questionnaire and an assessment questionnaire. The qualitative analysis shows significant differences between genders in the group of Russian speakers. The major finding was that Russian males were more judgmental and direct in their complaints, but they were also more humorous and ironic than Russian females. Fewer differences were observed in the group of American speakers and American L2 learners of Russian. The findings indicate similar gender differences within each group and across groups in terms of strategy selection and the number of words. Some of the differences were statistically significant.The findings of the interlanguage analysis open areas for pedagogical intervention so that L2 learners better understand how to address males and females, as well as which linguistic strategies to use to minimize offense while negotiating a problem in Russian culture.
Language of Cyber-Politics: "Imaging/Imagining" Communities
Authors: Baider Fabienne H. , Constantinou Maria
Published: December 2014

Assuming that “YouTube provides a deindividuated interactional context where social identity, including ethnic identity, is salient” (Garcés-Conejos Blitvich et al. 2013, our emphasis), we focus our analysis on the online discussants’ identity narratives (i.e. avatars, pseudonyms and comments) in order to investigate what makes each identity narrative into a cohesive specific ethos and how this ethos is coherent with the positioning of the party and their leaders. Our methodology includes qualitative analysis (avatars and pseudonyms) as well as a quantitative approach (comments vs leadership speeches). Our findings confirm that the emotions and ideologies salient in the leadership speeches and keywords are perpetuated, reinvented and re-enacted in avatars, pseudonyms and comments, constructing therefore a coherent virtual community. We also conclude that the ethos of this virtual community was built on the concept of resisting the loss of sovereignty (among other things to resist), symbolically co-constructed with myths, memories and a glorious past, instilling pride and unity, while cultivating anger, resentment and contempt against the “enemy”.
Improving Delivery of Bright Futures Preventive Services at the 9- and 24-Month Well Child Visit
Authors: Duncan Paula M. , Pirretti Amy , Earls Marian F. , Stratbucker William , Healy Jill A. , Shaw Judith S. , Kairys Steven
Published: December 2014

OBJECTIVES:

To determine if clinicians and staff from 21 diverse primary care practice settings could implement the 2008 Bright Futures Guidelines for Health Supervision of Infants, Children, and Adolescents, 3rd edition recommendations, at the 9- and 24-month preventive services visits.

METHODS:

Twenty-two practice settings from 15 states were selected from 51 applicants to participate in the Preventive Services Improvement Project (PreSIP). Practices participated in a 9-month modified Breakthrough Series Collaborative from January to November 2011. Outcome measures reflect whether the 17 components of Bright Futures recommendations were performed at the 9- and 24-month visits for at least 85% of visits. Additional measures identified which office systems were in place before and after the collaborative.

RESULTS:

There was a statistically significant increase for all 17 measures. Overall participating practices achieved an 85% completion rate for the preventive services measures except for discussion of parental strengths, which was reported in 70% of the charts. The preventive services score, a summary score for all the chart audit measures, increased significantly for both the 9-month (7 measures) and 24-month visits (8 measures).

CONCLUSIONS:

Clinicians and staff from various practice settings were able to implement the majority of the Bright Futures recommended preventive services at the 9- and 24-month visits at a high level after participation in a 9-month modified Breakthrough Series collaborative.

This Technical Report was reaffirmed February 2021.

Retinopathy of prematurity (ROP) remains a significant threat to vision for extremely premature infants despite the availability of therapeutic modalities capable, in most cases, of managing this disorder. It has been shown in many controlled trials that application of therapies at the appropriate time is essential to successful outcomes in premature infants affected by ROP. Bedside binocular indirect ophthalmoscopy has been the standard technique for diagnosis and monitoring of ROP in these patients. However, implementation of routine use of this screening method for at-risk premature infants has presented challenges within our existing care systems, including relative local scarcity of qualified ophthalmologist examiners in some locations and the remote location of some NICUs. Modern technology, including the development of wide-angle ocular digital fundus photography, coupled with the ability to send digital images electronically to remote locations, has led to the development of telemedicine-based remote digital fundus imaging (RDFI-TM) evaluation techniques. These techniques have the potential to allow the diagnosis and monitoring of ROP to occur in lieu of the necessity for some repeated on-site examinations in NICUs. This report reviews the currently available literature on RDFI-TM evaluations for ROP and outlines pertinent practical and risk management considerations that should be used when including RDFI-TM in any new or existing ROP care structure.
Use of Electronic Health Record Systems by Office-Based Pediatricians
Authors: Lehmann Christoph U. , O’Connor Karen G. , Shorte Vanessa A. , Johnson Timothy D.
Published: December 2014

BACKGROUND AND OBJECTIVES:

The American Recovery and Reinvestment Act of 2009 accelerated the implementation of electronic health records (EHRs) in pediatric offices. We sought to determine the prevalence and functionalities of EHRs, as well as pediatricians’ perceptions of EHRs.

METHODS:

An 8-page self-administered questionnaire was sent randomly to 1621 nonretired US members of the American Academy of Pediatrics from July to December 2012. Responses were compared with a similar survey in 2009.

RESULTS:

The percent of pediatricians, who are using EHRs, increased significantly from 58% in the 2009 survey to 79% in 2012. Only 31% used an EHR considered to have basic functionality, and only 14% used a fully functional EHR. Providers with equal or greater than 20% public insurance patients (threshold for meaningful use eligibility) were more likely to have an EHR. Solo/2-physician practices were least likely to have adopted an EHR. Younger physicians were more likely to consider an EHR important to quality care and perceived the presence of an EHR as more important in recruiting.

CONCLUSIONS:

The number of office-based pediatricians who are using an EHR has steadily risen to almost 80%. EHR cost and reduction in productivity remain serious concerns. Despite the widespread adoption of EHRs by pediatricians, only few use a basic or fully functional EHR and even fewer have added pediatric functionality. There is a role for the EHR certification process to advance functionalities used by pediatricians and to increase efficiency, data exchange capability, and general EHR functionality.
Early Childhood Neurodevelopment After Intrauterine Growth Restriction: A Systematic Review
Authors: Levine Terri A. , Grunau Ruth E. , McAuliffe Fionnuala M. , Pinnamaneni RagaMallika , Foran Adrienne , Alderdice Fiona A.
Published: December 2014

BACKGROUND AND OBJECTIVE:

Children who experienced intrauterine growth restriction (IUGR) may be at increased risk for adverse developmental outcomes in early childhood. The objective of this study was to carry out a systematic review of neurodevelopmental outcomes from 6 months to 3 years after IUGR.

METHODS:

PubMed, Embase, PsycINFO, Maternity and Infant Care, and CINAHL databases were searched by using the search terms intrauterine, fetal, growth restriction, child development, neurodevelopment, early childhood, cognitive, motor, speech, language. Studies were eligible for inclusion if participants met specified criteria for growth restriction, follow-up was conducted within 6 months to 3 years, methods were adequately described, non-IUGR comparison groups were included, and full English text of the article was available. A specifically designed data extraction form was used. The methodological quality of included studies was assessed using well-documented quality-appraisal guidelines.

RESULTS:

Of 731 studies reviewed, 16 were included. Poorer neurodevelopmental outcomes after IUGR were described in 11. Ten found motor, 8 cognitive, and 7 language delays. Other delays included social development, attention, and adaptive behavior. Only 8 included abnormal Doppler parameters in their definitions of IUGR.

CONCLUSIONS:

Evidence suggests that children are at risk for poorer neurodevelopmental outcomes following IUGR from 6 months to 3 years of age. The heterogeneity of primary outcomes, assessment measures, adjustment for confounding variables, and definitions of IUGR limits synthesis and interpretation. Sample sizes in most studies were small, and some examined preterm IUGR children without including term IUGR or AGA comparison groups, limiting the value of extant studies.

Published: December 2014

AbstractThe aim of this study is to determine what happens when the subject of probability is taught via educational games. Participants in the research were fourth-grade students (N= 24, aged 9-10) who were taught for 3 class hours (each 40 minutes) by their teacher. The designed games were played among groups of 3-4 students. Data was gathered from 8 selected students’ responses to semi-structured interviews, the teacher’s views about the process, researchers’ evaluations of students’ reflections, students’ journal entries regarding the process, and audio and video recordings of students’ interactions. The findings were presented according to data collection sources. Evidence suggested that game-based teaching facilitated understanding, enhanced students’ participation and motivation, enabled them to work with peers, helped them overcome math anxiety, provided an amusing learning environment, although it also resulted in classroom management difficulty and a noisy learning environment. Key words: cooperative learning; game-based teaching; mathematics education; opinions of teacher and students; probability.  ---  SažetakCilj istraživanja bio je odrediti što će se dogoditi kada vjerojatnost poučavamo posredstvom obrazovne igre.

AComparing ’Ex catedra’ and IT-Supported Teaching Methods and Techniques: Policy of Teaching Practice/Usporedba ex catedra i računalno potpomognutih metoda i tehnika poučavanja: politika nastavne prakse
Authors: Dobrota Marina , Benković Slađana
Published: December 2014

AbstractTeaching at higher education institutions in Serbia still relies on traditional ‘ex catedra’ methods and is mostly based on acquiring factual knowledge, which discourages student participation in the learning process, as well as any initiative on their part. The aim of the paper is to point to the implementation of the traditional ‘ex catedra’ versus the use of IT-supported teaching methods and techniques. The underlying idea is that professors’ abilities depend on their familiarity with different teaching methods and techniques, their knowledge of a foreign language, and the use of ICT. The data analysis has confirmed that teachers do differ from each other with respect to their academic titles: senior teachers (associate and full professors) use traditional methods more frequently than younger teachers do. In general, all teachers should incorporate modern trends into their teaching styles, since traditional teaching methods and techniques are used more often than IT-supported ones.Key words:  IT-supported teaching; teaching methods; teaching techniques; traditional ‘ex catedra’ teaching; universities in Serbia---SažetakNa visokoškolskim institucijama u Srbiji poučavanje se još uvijek oslanja na tradicionalne ex catedra metode, većinom se temelji na usvajanju činjeničnoga znanja, čime se studenti obeshrabruju od sudjelovanja u procesu učenja i poduzimanja inicijative. Cilj ovoga rada jest uputiti na upotrebu tradicionalnog ex catedra poučavanja u usporedbi s računalno potpomognutim metodama i tehnikama poučavanja. Smatra se da sposobnosti nastavnika ovise o njihovu poznavanju različitih metoda i tehnika poučavanja, znanja stranoga jezika i upotrebe informacijsko-komunikacijskih tehnologija. Analiza rezultata potvrdila je da se nastavnici međusobno razlikuju s obzirom na akademska zvanja: iskusniji nastavnici (izvanredni i redoviti profesori) češće se koriste tradicionalnim metodama od njihovih mlađih kolega. Općenito, svi bi nastavnici trebali uključiti moderne trendove u svoje stilove poučavanja, s obzirom na to da se tradicionalne metode i tehnike koriste češće od onih računalno potpomognutih.Ključne riječi:  metode poučavanja; računalno potpomognuto poučavanje; sveučilišta u Srbiji; tehnike poučavanja; tradicionalno ex catedra poučavanje.
Exploiting geotagged resources to spatial ranking by extending HITS algorithm
Authors: Tri Nguyen , Jung Jason
Published: December 2014

With a large amount of geotagged resources from smart devices, it is
important to provide users with intelligent location-based services.
Particularly, in this work, we focus on spatial ranking service, which can
retrieve a set of relevant resources with a certain tag. This paper designs
ranking algorithm in order to find out a list of locations which are
collected from geotagged resources on SNSs. As extending HITS algorithm
[13], we propose a novel method (called GeoHITS) that can analyze an
undirected 2-mode graph composed with a set of tags and a set of locations.
Thereby, meaningful relationships between the locations and a set of tags
are discovered by integrating several weighting schemes and HITS algorithm.
To evaluate the proposed spatial ranking approach, we have shows the
experimental results from the recommendation applications.

Levelized Product Cost: Concept and Decision Relevance
Authors: Reichelstein Stefan , Rohlfing-Bastian Anna
Published: December 2014

We examine a life-cycle cost concept that applies to both manufacturing and service industries in which upfront capacity investments are essential. Borrowing from the energy literature, we refer to this cost measure as the Levelized Product Cost (LC). Per unit of output, the levelized cost aggregates a share of the initial capacity investment with periodic fixed and variable operating costs. We relate this cost measure to the notion of full cost, as commonly calculated in managerial accounting texts. Our analysis identifies conditions under which the LC can be interpreted as the long-run marginal product cost. In particular, the LC is the relevant unit cost that firms should impute for investments in productive capacity.
The Value and Credit Relevance of Multiemployer Pension Plan Obligations
Authors: Chen Ting , Martin Xiumin , Mashruwala Christina A. , Mashruwala Shamin D.
Published: December 2014

We investigate whether multiemployer defined-benefit pension plan (MEPP) underfunding is priced by shareholders and creditors. Prior to the FASB's new MEPP standard (effective December 2011), when the disclosures on such plans were sparse, we find evidence (some evidence) that our estimate of a firm's share of MEPP underfunding is credit (value) relevant. We also find some evidence that a proxy for the funded status of a firm's MEPPs is incrementally value relevant over and above the firm's cash contributions, but no evidence that it is credit relevant. Furthermore, an estimate of MEPP underfunding that incorporates the additional disclosures required under the new MEPP standard is value and credit relevant, both individually and incrementally, over and above our old estimate. Overall, our findings suggest that shareholders and creditors view MEPP underfunding as a debt-like obligation and that the additional MEPP disclosures under the new standard are useful to market participants.
Information Complementarities and Supply Chain Analysts
Authors: Luo Shuqing , Nagarajan Nandu J.
Published: December 2014

This study examines the antecedents and consequences of analysts choosing to become supply chain analysts (i.e., analysts following both a supplier and its major customer). We find that information complementarities between firms in the same supply chain, between a supplier firm and its industry peer firms, and between the supplier's major customer and other firms in analysts' portfolio affect their supply chain specialization decision. The potential revenues supplier firms generate for analysts' brokerage houses also significantly affect this decision. While supply chain analysts achieve superior forecast performance compared to non-supply chain analysts for supplier firms, they provide lower-quality forecasts for other firms in their portfolios. These findings suggest that analysts allocate resources strategically. Our results are robust to techniques designed to address the potential endogeneity of analysts' supply chain portfolio choices.
Effect of Oxygen Tension on Tissue-Engineered Human Nasal Septal Chondrocytes
Authors: Twu Chih-Wen , Reuther Marsha S. , Briggs Kristen K. , Sah Robert L. , Masuda Koichi , Watson Deborah
Published: December 2014

Tissue-engineered nasal septal cartilage may provide a source of autologous tissue for repair of craniofacial defects. Although advances have been made in manipulating the chondrocyte culture environment for production of neocartilage, consensus on the best oxygen tension for in vitro growth of tissue-engineered cartilage has not been reached. The objective of this study was to determine whether in vitro oxygen tension influences chondrocyte expansion and redifferentiation. Proliferation of chondrocytes from 12 patients expanded in monolayer under hypoxic (5% or 10%) or normoxic (21%) oxygen tension was compared over 14 days of culture. The highest performing oxygen level was used for further expansion of the monolayer cultures. At confluency, chondrocytes were redifferentiated by encapsulation in alginate beads and cultured for 14 days under hypoxic (5 or 10%) or normoxic (21%) oxygen tension. Biochemical and histological properties were evaluated. Chondrocyte proliferation in monolayer and redifferentiation in alginate beads were supported by all oxygen tensions tested. Chondrocytes in monolayer culture had increased proliferation at normoxic oxygen tension (p = 0.06), as well as greater accumulation of glycosaminoglycan (GAG) during chondrocyte redifferentiation (p < 0.05). Chondrocytes released from beads cultured under all three oxygen levels showed robust accumulation of GAG and type II collagen with a lower degree of type I collagen immunoreactivity. Finally, formation of chondrocyte clusters was associated with decreasing oxygen tension (p < 0.05). Expansion of human septal chondrocytes in monolayer culture was greatest at normoxic oxygen tension. Both normoxic and hypoxic culture of human septal chondrocytes embedded in alginate beads supported robust extracellular matrix deposition. However, GAG accumulation was significantly enhanced under normoxic culture conditions. Chondrocyte cluster formation was associated with hypoxic oxygen tension.
CD8+ T Cells Implicated in the Pathogenesis of Allergic Fungal Rhinosinusitis
Authors: Pant Harshita , Macardle Peta
Published: December 2014

Fungi in paranasal sinuses are characteristic and considered a major pathogenic factor in a subset of chronic rhinosinusitis (CRS) patients, known as allergic fungal rhinosinusitis (AFRS). CD8+ T cells are enriched in AFRS sinuses but their role in fungal-specific responses is unknown. Alternaria alternata– and Aspergillus fumigatus–specific T lymphocyte responses were investigated in 6 AFRS patients, 10 eosinophilic mucus CRS (EMCRS) patients, 10 CRS with nasal polyps (CRSwNPs) patients, 6 allergic rhinitis with fungal allergy (ARFA) patients, and five controls. Fungal-specific proliferation of human peripheral blood mononuclear cells (PBMCs) was studied prospectively. Proliferating cells were examined for CD3, CD4, CD8, and CD25 expression. Relevant clinical characteristics, fungal allergy, detection of fungi in sinuses, and CD4+ and CD8+ composition of sinus T cells were also examined. CD4+ T-cell division to fungi occurred in all samples, regardless of fungal allergy or CRS. Fungal-specific CD8+ T-cell division occurred in all ARFA and control samples and the majority of CRSwNP patients; however, CD8+ T cells failed to proliferate in AFRS and EMCRS patients. The CD8+ T cells from AFRS patients also did not up-regulate the activation marker, CD25, with fungal antigen exposure. Presence of A. alternata– and A. fumigatus–specific CD4+ and CD8+ T-cell proliferation in healthy individuals, ARFA, and CRSwNP patients suggests that both T-cell subsets may be important in immune responses to these fungi. In AFRS and EMCRS patients, only fungal-specific CD4+ T-cell proliferation occurred; hence, a lack of CD8+ T-cell proliferation and activation in the presence of sinus eosinophilic mucus in these patients, regardless of fungal allergy, is a novel finding. This raises the question whether a dysfunctional CD8+ T-cell response predisposes to ineffective clearance and accumulation of fungi in the sinuses of susceptible patients.

Effects of Douglas fir on forest biodiversity

Under climate change, forestry in Switzerland promotes the increased cultivation of exotic Douglas fir (Pseudotsuga menziesii), as Douglas fir is more drought-resistant than native spruce. However, nature conservation organisations fear that enhanced planting of Douglas fir will negatively affect biodiversity and that Douglas fir has invasive potential. Based on the existing scientific and grey literature, we compile the present knowledge on the effects on forest habitats and biodiversity and the invasiveness of Douglas fir in Central Europe. The cultivation of Douglas fir does not seem to have any additional negative effects on soils as compared to native conifers, and its effects on biodiversity are diverse and often inconsistent. Overall, there is often a shift in species composition and in the dominance ratio for most studied groups of organisms (e.g. fungi, plants, arthropods, birds) in Douglas fir stands. Although natural regeneration of Douglas fir does occur in many regions of Central Europe, its extent, site-specificity and frequency and, therefore, the invasiveness of Douglas fir are not yet clear. We identified the following knowledge gaps: 1) Douglas fir should be studied along mixture gradients with other tree species, especially beech, in order to determine threshold values at which negative effects of biodiversity begin to appear. 2) The effects of Douglas fir on Red List, priority or characteristic forest species have not yet been thoroughly evaluated. 3) Frequency of natural regeneration and dispersal potential of Douglas fir in Central Europe should be assessed. Filling these knowledge gaps will allow a more reliable and integral assessment of the biodiversity effects of Douglas fir and its invasive potential.

Pollen morphology of the tribe Phyllodoceae (Ericoideae, Ericaceae) and its taxonomic significance
Authors: Sarwar A.K.M. Golam , Takahashi Hideki
Published: December 2014

Pollen morphology of 13 taxa belonging to 5 genera of the tribe Phyllodoceae (Ericaceae) was examined by means of light and scanning electron microscopy (LM and SEM, respectively), or SEM alone. In Phyllodoceae, 3-colpor(oid)ate, minute to medium, oblate pollen grains are united usually in tetrahedral tetrads. Pollen tetrads are generally characterized by the presence of viscin threads except Elliottia pyroliflora, Epigaea asiatica and Phyllodoce caerulea. The absence of viscin threads might indicate to a secondary loss, since these are present at least in some species within all the genera of Phyllodoceae. The pollen morphological data confirm the infra- and inter-generic relationships as identified by molecular phylogeny of Phyllodoceae and/or vice-versa. Although various palynological characters were found to be taxonomically important at different taxonomic levels, the apocolpial exine sculpture is emerged as one of the most important palynological features of systematic importance. The rugulate apocolpial exine with striate secondary sculpture and a reduced colpus might be apomorphic palynological character states for this tribe and Ericaceae as well. Hitherto, it is the first SEM study of Rhodothamnus pollen.DOI: http://dx.doi.org/10.3329/bjpt.v21i2.21351Bangladesh J. Plant Taxon. 21(2): 129-137, 2014 (December)

Published: December 2014

Groundwater of Chapai Nawabganj town has been studied using hydrogeological, hydrochemical and environmental isotope (?18O, ?2H, ?13C, 3H and 14C) data. Aquifer underneath the study area is divided into unconfined to semi-confined Holocene alluvial floodplain aquifer and confined Plio-Pleistocene Dupi Tila sandstone aquifer. Chemical composition of groundwater is characterized by high concentrations of Mg2+, Na+, Ca2+, HCO3-, FeTotal, and low concentrations of Mn2+, NO3 - and PO4 3-. Groundwater samples are mainly Mg-Ca-HCO3 and Na-Mg-Ca-HCO3 types and Na-Mg-Ca-Cl-HCO3 type of water is also found at some places. Based on Cl- and SO42- concentrations groundwater is normal chloride and normal sulphate water, respectively. In terms of SAR and EC values water is excellent for irrigation purpose. The isotopic composition also suggests some segregation of groundwater from the different aquifers and indicates different ages of recharge.

A total of 72 mice were used for an experimental model of intestinal amoebiasis developed in the Swiss albino mice dividing into three groups, experimental immunocompetent mice group (Group-A), experimental immunodepressed mice group (Group-B) and control group (Group-C). The inoculum (106 cells of Entamoeba histolytica/0.2 ml of medium) was used to inoculate into the caecum of the experimental groups of mice in the ICDDR,B laboratory, Dhaka. The mice were sacrificed at 5, 10, 15, 20, 25 and 30th days after inoculation for observation of caecal lesions and gross pathologic changes and histopathological analysis. The animals in the experimental two groups and control did not develop any caecal amoebiasis. The culture results of the stool of the mice which were inoculated with the inoculum of E. histolytica were found to be positive on the first 10 days after post caecal inoculation. After 10 days, the culture results were negative and the antiamoebic antibody levels of all animals were also found negative.
