Can miRNA Biomarkers Be Utilized to Improve the Evaluation and Management of Pancreatic Cystic Lesions?
Authors: Lee Linda S. , Szafranska-Schwarzbach Anna E. , Andruss Bernard F. , Conwell Darwin L. 
Published: October 2013

AbstractThis article reviews the current strategies and challenges of diagnosing pancreatic cystic lesions, and presents an overview of molecular tools that are available to enhance diagnostic accuracy. Specifically, we highlight the emergence of microRNAs (miRNAs) as diagnostic markers. miRNA signatures have been reported for both solid tissue and biofluid specimens, including cyst fluid, collected from patients with solid and cystic pancreatic lesions. These miRNA signatures offer the opportunity to improve molecular characterization of pancreatic lesions, to help guide clinical management through early diagnosis and informed prognosis, and to provide novel therapeutic targets for pancreatic cancer.
Sexual selection, range size and population size
Authors: Møller Anders Pape , Garamszegi László Zsolt 
Published: October 2013

Abstract
Sexual selection may impose fitness costs on both males and females due to the costs of developing and maintaining exaggerated sexual signals, reducing average fitness in strongly sexually selected species. Such reductions in average fitness could affect local extinction risk and hence distribution range. However, given that both sexually monochromatic and dichromatic species are common and widespread, benefits of sexual selection must be invoked to maintain equilibrium. We tested for differences in breeding range size and population size between monochromatic and dichromatic species of birds in a comparative analysis of species from the Western Palaearctic. In an analysis of standardized linear contrasts of the relationship between sexual dichromatism and range size and population size, respectively, that controlled for similarity among taxa due to common descent, we found no significant relationship. However, when we analyzed carotenoid-based sexual dichromatism sexually dichromatic species had larger distribution areas and higher northernmost distribution limits, but not southernmost distribution limits than sexually monochromatic species. In contrast, melanin-based sexual dichromatism was not significantly associated with range size or population size. Therefore, population density of sexually dichromatic species with carotenoid-based coloration was lower than that of monochromatic species, because dichromatic species had similar population sizes but larger ranges than monochromatic species. These findings suggest that the different physiological roles of pigments associated with sexual dichromatism have effects on total range size of birds.

Published: October 2013

AbstractA recently published checklist of Hungarian louse fauna (Insecta: Phthiraptera) listed 279 species and subspecies which have been recorded in Hungary. According to that checklist several louse species still await detection in Hungary, and many of the previously reported louse species have not been found on all expected host species yet. Our faunistical survey on avian lice started in 2005 at Ócsa Bird Ringing Station, resulting hundreds of ectoparasite samples collected from over 70 bird species. Additionally, our louse collection has grown by collecting samples in other research projects focusing on various bird species, and by sampling cadavers before taxidermy in the Bird Collection of the Hungarian Natural History Museum. As the results of a preliminary exploration of this collection, we list 20 louse species which are new to the Hungarian fauna, as well as the first Hungarian records of 17 host-parasite associations. We also found 3 louse-bird association records new for the World fauna.
Circulating serum sVCAM-1 concentration in advanced ovarian cancer patients: correlation with concentration in ascites
Authors: Jakimovska Marina , Cerne Katarina , Verdenik Ivan , Kobal Borut 
Published: October 2013

Abstract
Background. Vascular cell adhesion molecule-1 (VCAM-1) is associated with ovarian cancer progression but the origin of its soluble form (sVCAM-1) in serum is not well investigated. The purpose of this study was to elucidate whether the concentration of sVCAM-1 in serum correlates with the concentration in ascites, that represents local tumour environment, and with systemic inflammation, various clinicopathological characteristics, and patient outcome.
Patients and methods. Thirty-six patients with advanced ovarian cancer were included in the study. Serum for sVCAM-1 analysis was obtained prior to surgery. Ascites samples were collected at the beginning of the operation. Clinical data were collected from patients’ medical records. sVCAM-1 in samples was analysed by flow cytometric bead-based assay. The mean follow-up period was 11 months (range 0-23) from the time of surgery.
Results. Serum sVCAM-1 concentrations are positively correlated to ascites sVCAM-1 concentrations. There was a weakly positive correlation of serum sVCAM-1 with tumour size and no correlation with inflammatory tumour markers, FIGO stage or grade. Higher concentrations of sVCAM-1 were associated with poor disease outcome (death from ovarian cancer) in almost all cases before chemotherapy was started.
Conclusions. This is the first study demonstrating that serum concentrations of sVCAM-1 in advanced ovarian cancer patients correlate with sVCAM-1 concentrations in ascites, thus expressing the biologic potential of malignant disease to metastasis, rather than systemic inflammation. Higher serum and ascites sVCAM-1 concentrations might have predictive potential for different biologic behaviour.
Growth and photosynthesis of Lemna minor L. exposed to different light conditions and sucrose supplies

Published: October 2013

Abstract
Duckweed (Lemna minor L.) is a model plant suitable for investigation into plant physiology, biochemistry and ecotoxicology. Depending on the type of the experiment, duckweed is cultivated on different nutrient media under various chamber conditions. In our work, duckweed was cultivated on Pirson-Seidel’s nutrient solution supplemented with 5, 7.5 or 10 g L-1 sucrose under cool white (CW) or Gro-Lux (GL) light sources. When different light sources and sucrose supplies are compared, a significant stimulative effect of GL light on duckweed grown on 7.5 and 10 g L-1 sucrose was seen to start on day 9. Considering photosynthetic performance the results showed that there were no significant differences in maximum quantum yield of PSII (Fv/Fm) after 7 and 16 days of exposure, regardless of light source and sucrose supply. Effective quantum yield of PSII (ΦPSII) decreased only after 16 days of exposure to 5 g L-1 sucrose under CW light. The higher growth rate and photosynthetic performance in plants exposed to GL light is a consequence of its spectral distribution resembling the action spectrum of photosynthesis. Furthermore, enhanced growth noticed in plants cultivated on higher sucrose contents (7.5 and 10 g L-1) indicated the promotive effect of sucrose in plants grown under low light conditions.
Flora of spoil heaps after hard coal mining in Trzebinia (southern Poland): effect of substratum properties
Authors: Woch Marcin W. , Radwańska Magdalena , Stefanowicz Anna M. 
Published: October 2013

Abstract
- The aim of the present study was to investigate the composition of spontaneous plant cover and the physicochemical properties of the substratum of spoil heaps of the Siersza hard coal mine in Trzebinia (southern Poland) abandoned in 2001. Floristic and soil analyses were performed in 2011. The substratum was very diverse in terms of texture (sand: 55-92 %, clay: 6-38 %), nutrient content (total C: 1.3-41.0 %, total N: 0.05-0.49 %, total Ca: 0.5-7.3 %) and pH (3.7-8.7). Moreover, total thallium concentration in the substratum was high, ranging from 6.0 to 14.6 mg kg-1. Plant cover varied from 50 to 95 %. The number of plant species per 4m2 varied from 6 to 29 and correlated negatively with total carbon content (r = -0.85, p < 0.01), and positively with sand content in the substratum (r = 66, p < 0.05). The highest number of species per area unit was observed on a humus substratum, where initial soil has developed on the part of carboniferous waste rock spoil under 20-30 year old trees, and the lowest on carbon shale with coal and culm. Among 197 plant species, most belong to Asteraceae, Fabaceae, Poaceae and Rosaceae families. Hemicryptophytes (49%) and terophytes (18%) predominated. The investigated area was primarily colonized by native species spread by the wind. However, invasive alien species also had a significant share (8%) in the plant cover.
Interactions between leaf macronutrients, micronutrients and soil properties in pistachio (Pistacia vera L.) orchards

Published: October 2013

Abstract
- The interactions between: (i) leaf dry matter macronutrietns, micronutrients and soil chemical properties, (ii) leaf macro- and micronutrients, (iii) soil macro- and micronutrients and (iv) soil chemical properties, and soil micro- and macronutrients in 50 pistachio orchards were investigated in leaves and soils by means of regression analysis. Most of the soils were deficient in plant-available P, Zn, Mn, Fe, and B, while they were excessively supplied with Cu. Leaf analysis showed that most of the trees were sufficient in K, Mg, Mn and B, but deficient in N, P and Fe, and excessive in Zn and Cu. It was found that almost all the significant elemental interactions occurring in pistachio leaves or soils were synergistic, contributing considerable quantities of available nutrients and, therefore, improving the nutrient status of pistachio trees, and the level of soil fertility. On the other hand, the interactions between K and Mg in leaves, and between soil pH and leaf N or soil Fe, Mn and B, were antagonistic. It is suggested that these results must be taken into account during fertilization of pistachio trees, in order to avoid nutritional disorders and to promote plant growth, productivity and nut quality.
Ramallah : la vie sur un volcan éteint
Authors: Heacock Roger 
Published: October 2013

La vie à Ramallah d’aujourd’hui est comparée sur les plans culturel, social et politique avec celle qui prévalait dans les années 1980, afin d’en dégager la réalité et les rouages du changement. D’une bourgade provinciale vivant entièrement à l’ombre de ce qui était l’authentique capitale palestinienne, Jérusalem, elle s’est transformée, suite à deux intifadas, le régime d’Oslo, l’enfermement, et le transfert des principaux organismes internationaux dans la ville, en nouvelle capitale d’une entité dépendante pour sa survie des apports intellectuels et matériels venus d’Occident. Pourtant, les relations sociales ne se sont pas transformées au point de rendre cette société entièrement méconnaissable. Les subalternes et même les élites de Ramallah restent en mesure de renouer avec une tradition insurrectionnelle bien rodée.
Le « développement économique » palestinien : miracle ou mirage ?
Authors: Salingue Julien 
Published: October 2013

Le Premier Ministre palestinien Salam Fayyad a démissionné le 13 avril 2013, après six années à la tête du gouvernement de l’Autorité Palestinienne de Ramallah. Les « années Fayyad » ont été, pour nombre d’observateurs, celles de la « reprise économique » dans les territoires palestiniens, ce dont témoigneraient les chiffres spectaculaires de la croissance. Mais une étude plus précise des trajectoires de l’économie palestinienne indique que cette dernière, loin de s’émanciper de la tutelle d’Israël et des pays donateurs, poursuit un long mouvement de déclin, qui témoigne du fait qu’il n’y aura pas de « solution économique » à la question palestinienne qui demeure, fondamentalement, une question politique.
Constitutional Making and Identity Construction in Occupied Palestine
Authors: Dabed Emilio 
Published: October 2013

The constitutional drafting in Palestine was seen by some people as another emancipatory step, as an opportunity to reassert Palestinian identity, and as a challenge to the Palestinian legacy of colonialism and occupation. However, in this article I argue that the role and impact of these legal processes were of a strikingly different nature. The starting point of the analysis is that the PA’s constitutional and institutional frame was designed under occupation, by and for a non sovereign entity, and it thus represents the product of an ongoing colonial conflict rather than the end of it. Within this context, the PA political/constitutional regime rather than being an emancipatory reassertion of Palestinian identity tended to reproduce some colonial patterns –i.e. the Palestinian non sovereign status, authoritarian forms of domination, and the division of the colonized/occupied population in social groups with different legal status and often antagonistic interests
Comment le « Printemps arabe » a-t-il négligé la question palestinienne ?
Authors: Mikaïl Barah 
Published: October 2013

Le « Printemps arabe » a largement occulté le conflit israélo-palestinien. Mais alors que les possibilités de règlement de ce différend n’ont en rien disparu, un ensemble de facteurs en ont compliqué les logiques et ressorts. L’éclatement de la scène inter-palestinienne est profond, cependant que les Etats arabes continuent à jouer un rôle ambivalent. Sur le plan international, les acteurs capables d’influer positivement sur la scène israélo-palestinienne ne s’en donnent pas les moyens. Par conséquent, le conflit israélo-palestinien continue à connaître un enfoncement abyssal qui semble encore plus éloigner les opportunités de sa résolution.
De la résistance armée à la résistance non-violente
Authors: Ravenel Bernard 
Published: October 2013

Dans sa lutte désormais centenaire, le mouvement national palestinien a traversé plusieurs périodes correspondant à des contextes géopolitiques très différents – l’Empire Ottoman, le mandat britannique, la création de l’Etat d’Israël, l’expulsion de la majorité de la population (Nakba) en 1948, le développement du mouvement nationaliste arabe et la constitution d’Etats arabes indépendants. Ces bouleversements de l’environnement géopolitique ont failli faire disparaître la Palestine comme sujet politique autonome sur la scène internationale. Confronté à un ennemi puissant soutenu par les principales puissances impériales du 20 e siècle (Grande-Bretagne, Etats-Unis), mais aussi stimulé par le mouvement mondial d’émancipation des peuples colonisés, le Mouvement national palestinien a cru un moment possible obtenir la libération par une lutte armée de longue durée soutenue en particulier par le monde arabe. Il a perdu ce pari au prix d’énormes destructions humaines et matérielles. Une volonté intacte de résistance l’ a amené à tirer les leçons de ses échecs politiques et militaires et à s’engager dans une résistance populaire non-violente qui fait l’admiration du monde et qui devrait lui permettre d’espérer d’être libéré de l’occupation militaire israélienne désormais condamnée par la quasi totalité de la communauté internationale.
Islam et pouvoir dans la Libye post-Kadhafi
Authors: Lounnas Djallil 
Published: October 2013

Cet article évalue les forces, les fondements et les composantes de la mouvance islamiste libyenne. Un temps soutien de Kadhafi, les Oulémas et les frères musulmans se sont alliés avec les salafistes djiahdistes lors de la révolution libyenne de 2011 afin de renverser le guide libyen. Aujourd’hui, les islamistes, force politique majeure, constituent un défi pour la nouvelle démocratie libyenne et notamment en ce qui a trait à leur éventuelle acceptation d’un « consensus minimum démocratique ». Les résultats des dernières élections et la progressive stabilisation, certes difficile, du pays laissent à penser toutefois que ce processus semble être en bonne voie et que les islamistes acceptent de jouer le jeu démocratique.
A Cross-sectional Retrospective Study of Survival of Amalgam Restoration in a Nigerian Teaching Hospital
Authors: Olaleye Ajinde Oluwasola 
Published: October 2013

ABSTRACT

Background
This is a cross-sectional retrospective study on survival of amalgam restoration in a Teaching Hospital in Nigeria. There has been no study on this particular subject in Nigeria despite the fact that there is an alarming increase in dental caries and the preferred choice of treatment for over 5 decades has been amalgam restoration.

Materials and methods
It is a retrospective study of dental records of the dental center over a period of 12 years setting certain criteria that must be met by such records. Those that fulfilled these criteria were then recalled for examination.

Results
Two hundred and ninety-four amalgam restorations were placed with primary placements forming 75.69 of all restorations carried out while replacements were 24.31%. Fractured restoration was the commonest cause of failure of restoration accounting for 66% of all replacement. Ditching formed 15.5%, recurrent caries 11.6%, dislodged restoration 5.3%. While cervical overhanging amalgam was 1.6%. 25%, 50%, 75% cumulative failure rate occurs at 4.2 and 6.9 and 9.2 years respectively. While at the same time 73.2 and 19.2% of the restorations lasted for 5 and 10 years respectively.

Conclusion
Primary placement is the preoccupation of the dentist's in Nigeria while replacement rate is low. However, while recurrent caries is the major cause of restoration failure in economies country in Europe and America, it is not the case in this study.

Morphometric Analysis and Characterization of Teeth Extracted from Mature Cystic Teratoma of the Ovary
Authors: Togoo Rafi Ahmed 
Published: October 2013

ABSTRACT
Mature cystic teratomas are a form of ovarian germ cell tumor and often called ‘dermoid cysts’ because they are mostly cystic. Many teratomas have teeth with morphologically identifiable crowns and roots. The objective of this study was to carry out morphometric measurements of teratomatous teeth extracted from a mature cystic teratoma excised from a 28-year-old female patient. The extracted teeth were stored in normal saline till they were subjected to morphometric analysis. All measurements were done using digital calipers (Derby, France), repeated twice and the average was recorded. The teeth were labeled as teratomatous tooth 1 (TT1), teratomatous tooth 2 (TT2) and teratomatous tooth 3 (TT3). The gross morphology of TT1 resembled a maxillary deciduous canine whereas TT2 and TT3 resembled a deciduous incisor and a mesioden respectively. The teratomatous broadly resembled normal intraoral teeth. With all of them primarily resembling maxillary deciduous teeth it would not be out of place to postulate that the displaced embryonic tissue leading to the formation of these was from the upper front region of the stomodeum.

Solitary Bone Cysts of the Mandible: Two Case Reports and a Review of Literature
Authors: Kotrashetti SM , Louis Archana , Neeli Arati S 
Published: October 2013

ABSTRACT

Background
The solitary bone cyst is an uncommon nonepithelial cyst. Clinically, the lesion is asymptomatic in the majority of cases and is often accidentally discovered on routine radiological examination, frequently during the second decade of life. Its pathogenesis is still not clearly understood. The majority of solitary bone cysts are located in the mandibular body. This article presents two case reports, one in whom a cyst was diagnosed on routine radiographic examination and other patient reported with dull ache and radiographic examination showed bilateral presentation of the cystic lesion.

Materials and methods
In both patients the biopsy was planned. On surgical opening the lesions presented empty cavities. Curettage was done and overlying bone sent for histopathological examination. Both patients were followed for 1 year.

Results
At follow-up visit both patients were examined clinically and radiographically. In both the patients resolution of the lesion was seen at follow-up visit.

Conclusion
Solitary bone cyst is a rare entity with typical clinical and radiographic features. However, confirmation of diagnosis can be made only by histological examination. Solitary bone cyst may be secondary to an underlying bone pathology. Solitary bone cyst of the head and neck may vary in presentation and severity. Surgical removal is the treatment of choice and provides a satisfying outcome.

Published: October 2013

ABSTRACT
Cystic lesions are frequent in the oral cavity. They are defined as a pathologic cavity with or without fluid or semifluid material. Radicular cysts are the most common odontogenic cystic lesions of inflammatory origin affecting the jaws. They are most commonly found at the apices of the involved teeth. This case report presents the successful surgical management of large infected radicular cyst involving entire body region of right side of mandible. We illustrate the possibility of healing of cystic periapical lesions with conservation of vital structures.

Ferrara Technique of Deep Anterior Lamellar Keratoplasty for Keratoconus Treatment
Authors: Torquetti Leonardo 
Published: October 2013

Abstract

Purpose
To report the first clinical results of application Ferrara's technique of deep anterior lamellar keratoplasty (FDALK) in patients with keratoconus.

Materials and methods
Thirty-four eyes of 34 patients with advanced keratoconus were included in the study. All patients were operated by the FDALK technique. Preoperative and postoperative uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), corneal topography and corneal astigmatism were evaluated. Intra- and postoperative complications are described.

Results
Uncorrected visual acuity improved in from 20/400 to 20/125; corrected visual acuity improved from 20/300 to 20/48. The mean follow-up was 19.3 months (sd: 7.1). Corneal topography (Pentacam®) showed significant corneal flattening in all cases. Microperforations of the Descemet's membrane, requiring conversion to penetrating keratoplasty, occurred in two cases.

Conclusion
The FDALK technique is a safe and effective technique to be applied in patients with keratoconus. Visual outcome is comparable to PK, with advantage of preserving recipient endothelium, which lessens the risk of endothelium rejection.
