Published: January 2014

Abstract
Beer is a complex mixture - over 400 different compounds have been characterized in beer. Significant health and product quality promoting benefits have been attributed to its bioactive secondary metabolites such as phenolics. Polyphenols and phenolic acids present in beer are natural antioxidants. The aim of the research was to characterize the bioactive compounds in Latvian barley beer, such as phenolic acids and flavanols. In an experiment, different lager-type beers produced in Latvia were analysed. The total phenolic content was determined spectrophotometrically according to the Folin-Ciocalteu colorimetric method and expressed as gallic acid equivalents. Individual phenolic compounds were determined using high performance liquid chromatography (HPLC). The antioxidant potential of beer was analyzed by the 2,2-diphenyl-1-picrylhydraziyl (DPPH) radical assays and expressed as micromoles of Trolox equivalents. The research showed that the total phenolic content of dark beer samples (320.8-863.6 mg GE L-1) was mostly higher than that of the light beers (300.9-475.2 mg GE L-1). In total, eleven phenols were determined in the analysed samples. Also the sum of individual phenolics in dark beer samples was higher than in the light beer brands. All beer samples exhibited a strong DPPH radical scavenging activity: from 441.3 to 1064.2 μmol TE L-1 for the light beer samples, and from 726.2 to 1748.7 μmol TE L-1 for the dark beer. The research suggests that composition of beer phenolic compounds was not dependent on the type of beer - light or dark.
FARM FAMILIES AND FUTURE OPTIONS – THE ROLE OF THE EXTENSION ADVISORY SERVICE IN SHAPING IRISH AGRICULTURE
Authors: McDonagh John , Farrell Maura , Mahon Marie 
Published: January 2014

Abstract
Agriculture across Europe is very much driven by the reforms initiated by the European Union (EU) and World Trade Organisation negotiations. Reforms have mobilised a shift in agricultural practices from production to a somewhat contested post-production and, more recently, multifunctional agriculture regime. Accompanying such change has been the debate on the future of farming, the role of agriculture within the countryside, and the extent to which the sector will maintain support from the Common Agricultural Policy (CAP) and the EU. Central to these discussions, in terms of bringing about beneficial change on farms and in rural areas, is the advice and direction available to farmers. The agricultural extension advisory services are an integral component of this process. This paper explores the position of public extension advisory services in Ireland and determines the extent to which these services are impacting the trajectory of modern agricultural practices within a framework of more traditional views of farmers and farm families.
THE PROCESS OF DEPOPULATION IN THE RURAL AREAS OF UKRAINE
Authors: Kuczabski Aleksander , Michalski Tomasz 
Published: January 2014

Abstract
This study gives an analysis of the diversification of the demographic situation in the rural areas of Ukraine in the years 1992-2011 in a regional depiction (it corresponds to the NUTS 2 division applied in the European Union). The demographic situation of the rural population is undergoing increasingly distinct deterioration. It is the worst in central Ukraine and relatively the best in its western part. This is an effect of political, economic and social processes initiated in today’s Ukraine after World War One. It overlaps with negative effects of the processes of political transformation taking place in already independent Ukraine. The chances of improving the demographic situation in rural areas are rather slim and depend on two factors: (1) a fundamental change in the state policy towards the Ukrainian countryside and (2) overcoming a prolonged socio-economic crisis.

Coupled Effect of Elevated Temperature and Cooling Conditions on the Properties of Ground Clay Brick Mortars
Authors: Ali Abd El Aziz Magdy , Abdelaleem Salh , Heikal Mohamed 
Published: January 2014

Abstract When a concrete structure is exposed to fire and cooling, some deterioration in its chemical resistivity and mechanical properties takes place. This deterioration can reach a level at which the structure may have to be thoroughly renovated or completely replaced. In this investigation, four types of cement mortars, ground clay bricks (GCB)/sand namely 0/3, 1/2, 2/1 and 3/0, were used. Three different cement contents were used: 350, 400 and 450 kg/m3. All the mortars were prepared and cured in tap water for 3 months and then kept in laboratory atmospheric conditions up to 6 months. The specimens were subjected to elevated temperatures up to 700°C for 3h and then cooled by three different conditions: water, furnace, and air cooling. The results show that all the mortars subjected to fire, irrespective of cooling mode, suffered a significant reduction in compressive strength. However, the mortars cooled in air exhibited a relativity higher reduction in compressive strength rather than those water or furnace cooled. The mortars containing GCB/sand (3/0) and GCB/sand (1/2) exhibited a relatively higher thermal stability than the others.
AN EXTENSION OF PENROSE’S INEQUALITY ON GENERALIZED INVERSES TO THE SCHATTEN p-CLASSES
Authors: Mecheri Salah 
Published: January 2014

Abstract
Let B(H) be the algebra of all bounded linear operators on a complex separable infinite dimensional Hilbert space H.
In this paper we minimize the Schatten Cp-norm of suitable affine mappings from B(H) to Cp, using convex and differential analysis (Gâteaux derivative) as well as input from operator theory. The mappings considered generalize Penrose’s inequality which asserts that if A+ and B+ denote the Moore-Penrose inverses of the matrices A and B, respectively, then
||AXB − C||2 ≥ ||AA+CB+B − C||2,
with A+CB+ being the unique minimizer of minimal ||:||2 norm. The main results obtained characterize the best Cp-approximant of the operator AXB.
Grounding-line dynamics and margin lakes
Authors: Fried M.J. , Hulbe C.L. , Fahnestock M.A. 
Published: January 2014

AbstractAt both corners of the now stagnant Kamb Ice Stream (KIS, West Antarctica) outlet, shear margins of different ages confine wedge-shaped areas with relatively flat, smooth surfaces that stagnated before the main trunk of the ice stream. We identify these features as lakes or past lakes, and consider scenarios for their development in a regional history of ongoing adjustment to grounding-line position. We focus here on the centuries leading up to the recent stagnation of KIS, a time when its grounding line appears to have advanced >100km from an earlier upstream location. Starting from stagnation of Crary Ice Rise and changes in the grounding zone of Whillans Ice Stream, we trace feedbacks associated with local thickening, ice grounding and thickness transients that both advance the grounding line and leave remnant lakes in their wake. These lakes in turn promote the development of secondary margins that may appear as ‘margin jumps’ in the ice record.
Numerical simulations of major ice streams in Western Dronning Maud Land, Antarctica, under wet and dry basal conditions
Authors: Kleiner Thomas , Humbert Angelika 
Published: January 2014

AbstractWe study the presence and effect of subglacial water on the motion of inland ice in western Dronning Maud Land, Antarctica. A full-Stokes model including three routing schemes for a thin film of subglacial water and a modification of a Weertman-type sliding relation, to account for higher sliding velocities under wet basal conditions, were used to perform 200 ka spin-up simulations on a 2.5 km grid. Subsequent 30 ka simulations with wet and dry basal conditions were analysed for the effects of sliding on the thermal regime and velocities. The occurrence of the major ice streams in this area is mainly controlled by the ice and bedrock geometry. Smaller glaciers only appear as pronounced individual glaciers when subglacial water is taken into account. The thermal regime is affected by creep instabilities produced by an ice rheology including a microscopic water content, leading to cyclic behaviour on millennial timescales of the ice flow and occurrence of temperate ice at the base.

Published: January 2014

ABSTRACT
Objective: In this study, we aimed to evaluate and compare the dentinal walls of root-end cavities for the presence of cracks after cavity preparation using US retrotips and Er: YAG laser. Materials and Methods: Fifty single-rooted teeth were prepared by Protaper NiTi rotary system and obturated by lateral condensation. Three milimeters of root-end was resected. Twenty teeth were prepared with US retrotip (Group 1), 20 teeth with Er: YAG laser (Group 2), and 10 teeth without retropreparation (control group). The root-end surfaces were examined under a scanning electron microscope (SEM). Then the cracks of the resected root surfaces were evaluated on microphotographs. Results: No statistically significant difference was detected between US Group and Laser Group for complete, incomplete, intradentinal, and total number of cracks (P = 0.47, P = 0.80, P = 0.69, P = 0.869, respectively). Conclusion: Statistical analysis revealed no significant effect of retropreparation technique on the development of apical cracks (P > 0.05).

Published: January 2014

ABSTRACT
Objective: To determine the level of Streptococcus mutans (S. mutans) in adults of Chandigarh and to correlate the dental caries in these individuals with their S. mutans titers. Materials and Methods: Salivary levels of Streptococcus mutans, using Dentocult SM commercial kits were estimated in 200, 25-35 year old adults (males and females). Streptococcus mutans were detected in 87% of the study sample. Score 2, representing 105 - 106 CFU/ml (Colony Forming Unit) of saliva was found to be most prevalent, i.e. in 80 of 200 adults, followed by score 1, depicting S mutans with <105 CFU/ml, in 56 of 200 adults and score 3, with bacterial titer <106 CFU/ml in 38 of 200 adults. Results: Dental caries, recorded using Møller′s index, was found to be maximum in individuals with score 3, followed by score 2,1 and 0, thereby showing a positive correlation of dental caries with increasing titers of S. mutans. This correlation was statistically highly significant in males with figures as 8.73 decayed surfaces at score 2 rising to 17.38 at score 3. The mean of DMFT was higher among females than in the males in the present study. Conclusion: The split up data in males and females, showed a positive association between caries experience and salivary S. mutans scores. The results of the study will serve as a baseline data for future planning of preventive programs in adults.

Published: January 2014

ABSTRACTObjectives: The aim of this study was to obtain information about senior dental students′ perceptions and self-confidence levels regarding endodontic practice. Materials and Methods: Anonymous survey forms were handed out to senior students at Yeditepe University, Faculty of Dentistry. The students were asked to score their level of confidence using a 5-point scale and comment about future practices. Results: The response rate of the survey was 88%. 11.9% expressed endodontics as the first branch in terms of difficulty. The majority (90.5%) indicated they would perform root canal treatments within their expertise limit in the future but refer difficult cases to an endodontist. Bleaching of endodontically treated teeth, managing flare-ups, placement of a rubber dam were procedures in which students reported the lowest confidence (2.55 ± 1.17, 3.24 ± 0.96, 3.24 ± 1.19, respectively). On the other hand, students felt the lowest confidence in the treatment of maxillary molars followed by mandibular molars (3.43 ± 1.02 and 3.93 ± 0.97, respectively). Students also reported the lowest confidence in root resorptions, endo-perio lesions, traumas, retreatments and apexifications (2.93 ± 1.16, 3.07 ± 0.89, 3.24 ± 0.85, 3.33 ± 1.7 and 3.36 ± 1.1, respectively). Conclusions: The results showing students′ lower confidence in more challenging aspects of dentistry may be related with the attitude of dental schools to refer these cases to post graduate students and instilling information about these cases on a theoretical basis only. Though there seems to be a tendency for students to refer challenging cases to a specialist in future, authorities should give priority to enhance the way information and experience is conveyed regarding various aspects of endodontic treatment.

Published: January 2014

ABSTRACTDental management of children with attention-deficit hyperactivity disorder (ADHD) often requires the need for pharmacological behavior management techniques such as the use of sedation. The purpose of this article is to describe a clinical case involving accidental aspiration of an Endodontic instrument during root canal therapy under sedation. To our knowledge, this is the first case report of aspiration of an Endodontic instrument and should serve to heighten the awareness with regard to aspiration during dental procedures under sedation. It also emphasizes the need for proper isolation techniques in patients treated under sedation, thereby preventing such complications.

Published: January 2014

ABSTRACTDental anomalies of number and forms may occur in the primary and permanent dentition. Various terms have been used to describe dental twinning anomalies: Germination, fusion, concrescence, double teeth, conjoined teeth, twinned teeth, geminifusion, and vicinifusion. Fused tooth is a developmental anomaly that is seen more frequently in the primary than the permanent dentition. Double tooth involving deciduous anterior teeth is found mostly in the mandible.Very few cases of nonsyndromic double primary molar have been reported in the literature. The succeeding permanent tooth is often found missing congenitally in the same region. This article reports a very rare unilateral occurrence of an anomalous, primary mandibular first macromolar formed by fusion with a dysmorphic premolar like supernumerary tooth in deciduous dentition period. Instead of agenesis of succedaneous tooth, the double tooth has been succeeded by normally developing mandibular first premolar in the same region.

Reappraisal of the removable partial denture as a treatment option for the shortened dental arch
Authors: Nassani Mohammad Zakaria , Tarakji Bassel , Baroudi Kusai , Sakka Salah 
Published: January 2014

ABSTRACTFor patients with shortened dental arches, many treatment options are available. The existing situation can be maintained by stabilizing the present dentition and improving the occlusion without extending the arch. Alternatively, the shortened dental arch can be extended by either a free-end saddle removable partial denture, cantilevered fixed bridge, or by an implant-supported prosthesis. The free-end saddle removable partial denture can be considered a simple, non-invasive, and relatively cheap treatment option for the shortened dental arch. It was believed that such prosthodontic rehabilitation would be beneficial for the patients in terms of improving oral functions. However, the existing literature indicates that the prognosis of free-end saddle removable partial denture is not predictable, it is problematic, and its contribution to oral functions in patients with shortened dental arches is considered to be dubious. This paper reviews and summarizes the current literature about the outcome of extending the shortened dental arch by a free-end saddle removable partial denture. It also outlines factors that may affect the prognosis of this prosthetic treatment.

Authors: Renard Sébastien , Paulin Roxane , Breuils‐Bonnet Sandra , Simard Serge , Pibarot Philippe , Bonnet Sébastien , Provencher Steeve 
Published: January 2014

Provirus integration site for Moloney murine leukemia virus (Pim‐1) is an oncoprotein overexpressed in lungs from pulmonary arterial hypertension (PAH) patients and involved in cell proliferation via the activation of the NFAT/STAT3 signaling pathway. We hypothesized that Pim‐1 plasma levels would predict the presence of PAH and correlate with disease severity. Pim‐1 plasma levels were measured at the time of catheterization in 49 PAH patients, including nonvasoreactive (n = 19) and vasoreactive idiopathic PAH (n = 5), and PAH related to connective tissue disease (n = 16) and congenital heart disease (n = 9). Fifty controls were also recruited. The capacity of Pim‐1 to discriminate PAH from controls and its association with disease severity were assessed. Pim‐1 plasma levels were higher in PAH than in controls (9.6 ± 4.0 vs. 7.2 ± 2.4 ng/mL, P > 0.01). Pim‐1 appropriately discriminated proliferative PAH from controls (AUC = 0.78 to 0.94 using ROC curves). Among PAH patients, Pim‐1 correlated with traditional markers of PAH severity. The 1‐year survival was 97% and 47% for PAH patients with baseline Pim‐1 levels lower and higher than 11.1 ng/mL, respectively (HR 11.4 (3.3‐39.7); P > 0.01). After adjustment for hemodynamic and biochemical variables, Pim‐1 levels remained an independent predictor of mortality (P > 0.01). Pim‐1 is a promising new biomarker in PAH.
Metabolism and Bioenergetics in the Right Ventricle and Pulmonary Vasculature in Pulmonary Hypertension
Authors: Archer Stephen L. , Fang Yong‐Hu , Ryan John J. , Piao Lin 
Published: January 2014

Pulmonary arterial hypertension (PAH) is a syndrome in which pulmonary vascular cross sectional area and compliance are reduced by vasoconstriction, vascular remodeling, and inflammation. Vascular remodeling results in part from increased proliferation and impaired apoptosis of vascular cells. The resulting increase in afterload promotes right ventricular hypertrophy (RVH) and RV failure. Recently identified mitochondrial‐metabolic abnormalities in PAH, notably pyruvate dehydrogenase kinase‐mediated inhibition of pyruvate dehydrogenase (PDH), result in aerobic glycolysis in both the lung vasculature and RV. This glycolytic shift has diagnostic importance since it is detectable early in experimental PAH by increased lung and RV uptake of 18F‐fluorodeoxyglucose on positron emission tomography. The metabolic shift also has pathophysiologic and therapeutic relevance. In RV myocytes, the glycolytic switch reduces contractility while in the vasculature it renders cells hyperproliferative and apoptosis‐resistant. Reactivation of PDH can be achieved directly by PDK inhibition (using dichloroacetate), or indirectly via activating the Randle cycle, using inhibitors of fatty acid oxidation (FAO), trimetazidine and ranolazine. In experimental PAH and RVH, PDK inhibition increases glucose oxidation, enhances RV function, regresses pulmonary vascular disease by reducing proliferation and enhancing apoptosis, and restores cardiac repolarization. FAO inhibition increases RV glucose oxidation and RV function in experimental RVH. The trigger for metabolic remodeling in the RV and lung differ. In the RV, metabolic remodeling is likely triggered by ischemia (due to microvascular rarefaction and/or reduced coronary perfusion pressure). In the vasculature, metabolic changes result from redox‐mediated activation of transcription factors, including hypoxia‐inducible factor 1α, as a consequence of epigenetic silencing of SOD2 and/or changes in mitochondrial fission/fusion. Randomized controlled trials are required to assess whether the benefits of enhancing glucose oxidation are realized in patients with PAH.
