Semitopological BL-Algebras and MV -Algebras
Authors: Zahiri O. , Borzooei R. A. 
Published: September 2014

Abstract
In this paper, by considering the notion of upsets, for any element x of a BL-algebra L, we construct a topology Tx on L and show that L-algebras with this topology formes a semitopological BL-algebras. Then we obtain some of the topological aspects of this structure such as connectivity and compactness. Moreover, we introduced two kinds of semitopological MV -algebra by using two kinds of definition of MV -algebra and show that they are equivalent.
On the Coset Category of a Skew Lattice
Authors: Costa João Pita 
Published: September 2014

Abstract
Skew lattices are noncommutative generalizations of lattices. The coset structure decomposition is an original approach to the study of these algebras describing the relation between its rectangular classes. In this paper, we will look at the category determined by these rectangular algebras and the morphisms between them, showing that not all skew lattices can determine such a category. Furthermore, we will present a class of examples of skew lattices in rings that are not strictly categorical, and present sufficient conditions for skew lattices of matrices in rings to constitute ^-distributive skew lattices
Single-Valley-Extended Continuous Solutions For The Feigenbaum’S Functional Equation ƒ(ϕ(x))=ϕ2(f(x))
Authors: Zhang Min 
Published: September 2014

Abstract
This work deals with the Feigenbaum’s functional equation in the broad sense

where ϕ2 is the 2-fold iteration of ϕ f(x) is a strictly increasing continuous function on r0; 1s and satisfies f(0)=0; f(x) <x; x Ɛ (0, 1]). Using constructive method, we discuss the existence of single-valley-extended continuous solutions of the above equation.
Coincidence and Fixed Point for Weakly Reciprocally Continuous Single-Valued and Multi-Valued Maps
Authors: Gairola Ajay , Singh Jay , Joshi Mahesh C. 
Published: September 2014

Abstract
In the present paper, we extend the concept ofWeak Reciprocal Continuity for a hybrid pair of single-valued and multi-valued maps and introduce (T; f)-completeness of the space. Further, we establish some results on the existence of coincidence and fixed points for the hybrid pair of maps. Our results generalize several well known results available in the literature
A System for Managing the Quality of Official Statistics
Authors: Biemer Paul , Trewin Dennis , Bergdahl Heather , Japec Lilli 
Published: September 2014

Abstract
This article describes a general framework for improving the quality of statistical programs in organizations that provide a continual flow of statistical products to users and stakeholders. The work stems from a 2011 mandate to Statistics Sweden issued by the Swedish Ministry of Finance to develop a system of quality indicators for tracking developments and changes in product quality and for achieving continual improvements in survey quality across a diverse set of key statistical products. We describe this system, apply it to a number of products at Statistics Sweden, and summarize key results and lessons learned. The implications of this work for monitoring and evaluating product quality in other statistical organizations are also discussed.
Interactions between Marek’s disease virus Rispens/CVI988 vaccine strain and adenovirus field strain in chicken embryo fibroblast (CEF) cultures
Authors: Niczyporuk J.S. , Woźniakowski G. , Czekaj H. , Samorek-Salamonowicz E. 
Published: September 2014

AbstractThe aim of the study was to determine the influence of adenovirus infection on the replication of Marek’s disease virus vaccine strain Rispens/CVI988 during in vitro co-infection studies. Adenovirus field strain JN-5/10j was isolated from sick chickens. The study was conducted in chicken embryo fibroblast cultures (CEF). Monolayers of CEFs were infected with Rispens strain and field adenovirus strain JN-5/10j with different doses (101.0-103.0TCID50) in the following manner: a) simultaneously, b) first, infection with Rispens strain and after 24 h infection with adenovirus strain JN-5/10j and c) infection with adenovirus strain JN-5/10j 24 h before infection with Rispens strain. After 18, 24, 48, 72, and 96 h of incubation, the copy number of the pp38 gene of Rispens strain was determined using Real-time PCR. The results indicated that the Adenovirus infection before the infection with Rispens strain reduced the replication of the pp38 gene after 48 h by 2 log10.
Influence of selected stool concentration techniques on the effectiveness of PCR examination in Giardia intestinalis diagnostics
Authors: Stojecki K. , Sroka J. , Karamon J. , Kusyk P. , Cencek T. 
Published: September 2014

AbstractGiardia intestinalis is a widespread parasitic protozoa which has great significance as a public health threat. Molecular diagnostics of stool sample can be unreliable because of the presence of inhibitors of enzymatic reactions. The aim of this study was to determine the effectiveness of selected pre-treatment methods of fecal samples for further PCR-based diagnostics of G. intestinalis, and the effect of each component of pre-treatment solutions on PCR reactions. Seven stool concentration techniques were compared. The results showed that the most efficient concentration method for stool sample preparation for detection of G. intestinalis by PCR is centrifugal flotation with Percoll (with saturated NaNO3as the flotation solution). This method is relatively inexpensive, less labor-intensive, and suitable for epidemiological monitoring and clinical investigations.
The splenocyte proliferative response and cytokine secretion in mice after 28-day oral administration of silver nanocolloid
Authors: Małaczewska J. 
Published: September 2014

Abstract
An increasing number of applications of silver nanoparticles in industry, medicine and everyday life means that the risk of exposure of the human organism to their potential harmful influence is growing. This study has sought to assess the effect of 28-day alimentary administration of different concentrations (0.25, 2.5 and 25 ppm) of a commercial silver nanocolloid on the proliferative activity and synthesis of cytokines by mouse splenocytes.
All of the analyzed doses of the colloid had a significant, albeit different, effect on the activity of splenocytes. At the lowest dose, a significant decrease in the proliferation of T cells and more intensive synthesis of pro-inflammatory cytokines, both by non-stimulated and LPS-stimulated cells, was observed. The intermediate dose, on the other hand, stimulated proliferation of B cells while producing a pro-inflammatory effect regarding the synthesis of cytokines. Finally, the highest dose decreased the synthesis of cytokines by non-stimulated cells, but after LPS stimulation, through the strong activation of the IL-10 synthesis, it raised the proliferation of B cells and decreased the synthesis of pro-inflammatory cytokines.
The results suggest that silver nanoparticles administered orally have an easy access to the peripheral organs of the immune system, such as the spleen, but the effect of long-term exposure of this organ to the effect of silver nanocolloid depends on several factors, including the dose of nanoparticles, and seems as difficult to predict.

Published: September 2014

AbstractThe aim of the study was to determine the effect of Jerusalem artichoke and probiotics on defence activity of intestinal cells of weaning pigs. One hundred eighty piglets (7 weeks old) were fed with basal feed supplemented with Jerusalem artichoke, Lactobacillus reuteri and Pediococcus pentosaceus. After 5 weeks, the piglets were slaughtered and the gastrointestinal contents and intestine samples were taken for analysis. Results demonstrated that in pigs fed basal diet with both probiotics and Jerusalem artichoke (5% of basal diet) (T3 group) had less (P<0.05) faecal Enterobacteriaceae microorganisms and coliforms and had more (P<0,05) faecal Lactobacillus than in pigs from other groups. Increase by 2% of Enterobacteriaceae and E.coli levels were seen only in control piglets (T1 group). E.coli O157 was found at the closing stage in the piglets fed basal diet with only Jerusalem artichoke powder (T2 group), but Salmonella enteritidis - only in T1 group. In jejunum of T2 group piglets, large deterioration of crypts, a moderate inflammation process and plasmocytes were seen, but in jejunum of T3 group piglets - branching of apical surface of villi, moderate degeneration and mitosis of enterocytes were observed. A moderate number of apoptotic cells in T2 group was found mainly in colon inflammation cells and plasmocytes, but for T3 group piglets - both in jejunum enterocytes and migrating cells. Our study indicated that β-defensin 2 and 3 expression in jejunum and colon segments were incresed in T1 and T2 groups. Findings suggest that feeding with probiotics and Jerusalem artichoke significantly improves the microbial contents, defence and regeneration processes in the intestine of pigs.

Published: September 2014

Abstract
The objective of the study was to evaluate the effect of inulin or dandelion, chicory and Jerusalem artichoke powder on lipid indices and fatty acid profile in fattener tissues. The experiment involved 120 crossbred pigs (PL × PLW) × Duroc with an initial body weight of 25.0 ± 0.5 kg. Animals were assigned into 6 groups. A diet for group I (control) did not comprise an inulin additive, group II and III received 2% inulin (water or water-alcohol extraction of inulin from chicory root, respectively), while the mixtures for group IV, V and VI contained 4% root powder from Jerusalem artichoke (topinambur), chicory or dandelion, respectively. The animals were slaughtered at 115 kg body weight. The samples of blood, liver and the muscle longissimus dorsi tissues as well as whole hearts were collected for analysis. Fatty acid profile, some lipid indices and crude fat and cholesterol content were evaluated. Dietary supplement of 40 g dandelion powder resulted in preferable significant changes in the blood lipid indices and fatty acids composition (increased PUFA share and decreased n-6/n-3 ratio).
Bone marrow-origin stem/progenitor cells in the mammary gland of heifers
Authors: Osińska E. , Godlewski M. M. , Wierzbicki M. , Motyl T. 
Published: September 2014

Abstract
The aim of the study was to estimate the size of bone marrow-origin stem/progenitor population in 2-year old nonpregnant Holstein-Friesian heifers. Quantitative and qualitative analysis was done using scanning cytometry and confocal microscopy of mammary tissue slices labelled with the combination of two markers: Sca-1 (marker of stem-progenitor cells) and CD45 (marker of hematopoietic cells). The average (±SEM) percentage of Sca-1POS CD45POS cells was 0.89 ± 0.21. They were localized mainly outside of mammary ducts, in the stroma and sometimes intraluminally. Our results indicate that the subpopulation of Sca-1POS cells bearing CD45 antigen may enrich the niche of mammary stem/progenitor cells from the bone marrow and participate in the growth of the mammary gland in post-pubertal heifers.

Abstract
The aim of this study was to determine serum selenium concentrations in Polish Konik horses residing in the Odra Delta Nature Park (Poland) and to evaluate the activity of glutathione peroxidase and Se content in testes of this horse breed. In over 95% of cases, serum Se concentration was below the optimal range, and none of the horses examined was deficient in this trace element. The lack of Se deficiency in the animals examined suggests however, that the Polish Konik horses have a natural ability to the optimal use of nutrients available in their life area. Testicular content of Se and GSHPx activity in the colts was higher than those found in stallions, and a positive relationship between these antioxidants was demonstrated. The differences in Se contents and GSHPx activities in testes between colts and stallions suggest that selenoenzymes play important roles during the puberty of male horses.
Association between decreased blood pressure and azotaemia in canine babesiosis
Authors: Zygner W. , Gójska-Zygner O. 
Published: September 2014

Abstract
Acute tubular necrosis (ATN) was described in canine babesiosis. Hypotension is considered as one of the factors which influence the development of hypoxic renal damage. In this study hypotension defined as mean arterial pressure (MAP) < 80 mmHg was detected in 7 out of 48 dogs (14.6%) infected with Babesia canis. Lower systolic arterial pressure (SAP), diastolic arterial pressure (DAP) and MAP were detected in azotaemic dogs infected with B. canis. Statistically significant negative correlations between blood pressures (SAP, DAP and MAP) and serum creatinine and urea concentrations showed the influence of decreased blood pressure on the development of azotaemia and is probably also associated with ATN in canine babesiosis.

Authors: Jarosz Ł.S. , Grądzki Z. , Śmiech A. , Kalinowski M. 
Published: September 2014

Abstract
Type C and type A of C. perfringens were detected in the seat of natural infections in silver foxes characterized by symptoms of haemorrhagic enterotoxemia. In all of the dead foxes characteristic changes were noted in the small intestine and parenchymatous organs. The production of alpha and beta toxins by isolated bacteria was confirmed by the bioassay using white mice and by PCR. The results of the drug sensitivity testing showed that isolated strains were highly susceptible to amoxicillin with clavulanic acid, metronidazole, doxycycline and penicillin with streptomycin
« Serious games » et recrutement : quels enjeux de recherche en gestion des ressources humaines ?
Authors: Galois-Faurie Isabelle , Lacroux Alain 
Published: September 2014

La présente étude se propose d’explorer un domaine émergent dans le champ des sciences de la gestion : l’usage d’outils de réalité virtuelle dans le processus de recrutement. Nous nous intéressons en particulier à l’utilisation croissante des serious games (ou jeux sérieux) par les entreprises. Cette utilisation croissante, qui trouve notamment écho dans la presse managériale, semble correspondre à une évolution profonde, en partie commandée par l’évolution technologique et par le souhait de certaines entreprises de mettre en place des procédés innovants pour susciter des candidatures ciblées et sélectionner efficacement les postulants. Notre revue de littérature, menée dans le domaine des sciences de gestion mais également dans les domaines de l’apprentissage médiatisé et de l’usage des jeux vidéo, a été complétée par une étude exploratoire auprès d’experts suivant la méthode Delphi. Ceci nous a permis de mettre en évidence les enjeux psychologiques et managériaux liés à l’utilisation des serious games dans le processus de recrutement, et de dégager un certain nombre de voies de recherche potentiellement fructueuses dans le domaine de la gestion des ressources humaines.
Les consultants dans la prévention des risques psychosociaux au travail : proposition d'une typologie de pratiques
Authors: Chakor Tarik 
Published: September 2014

L’objectif de cet article est d’analyser les pratiques des consultants dans la prévention des risques psychosociaux au travail (RPS). Phénomène au cœur de l’actualité mais mal défini, les RPS peuvent faire l’objet d’une approche restrictive, tendant à individualiser le risque, à limiter la responsabilité de l’employeur et à soigner le travailleur ; ou d’une approche élargie, appréhendant la dimension organisationnelle du risque, étendant la responsabilité de l’employeur et soignant le travail et son organisation. Il s’agit d’un champ stratégique autour de l’imputation de la responsabilité du risque, opposant principalement employeurs et représentants du personnel. Sur la base d’un échantillon de 37 consultants et d’une démarche exploratoire qualitative, ancrée dans le paradigme interprétativiste, nous avons souligné l’hétérogénéité de leurs pratiques, pouvant se traduire dans le choix du commanditaire, le profil disciplinaire du consultant, le contexte d’intervention et les modalités de questionnement, d’analyse et de « mise en marche » de la démarche. Il existe ainsi trois « pratiques-type » : les pratiques co-constructives, adaptatives et militantes. Inscrits dans une logique de marché, les consultants sont des acteurs hybrides, oscillant entre co-construction et adaptation, voire militantisme, en fonction des marges de manœuvre et des besoins du commanditaire.

Published: August 2014

We report an interesting case of a 19 year old female with findings on MRI suggestive of viral encephalitis. An extensive workup was negative for infectious causes and she was subsequently diagnosed with anti-NMDA encephalitis. Anti-NMDA encephalitis is a highly lethal but treatable form of autoimmune encephalitis that has recently been characterized. It is frequently found in young women and associated with an underlying teratoma. Although rare, this diagnosis should be considered in young females for whom a rapid onset of encephalitis cannot be explained by more common causes.
Congenital Indifference to Pain: An Illustrated Case Report and Literature Review
Authors: Golshani Ashkahn , Kamdar Ankur , Spence Susanna , Beckmann Nicholas 
Published: August 2014

Congenital indifference to pain is a rare and debilitating congenital disease. Individuals with the disorder may have one or a combination of sensory or autonomic deficits, which can range from lack of mechanical nociception, diminished ability to detect heat and cool stimulation, to the devastating and fatal form which includes autonomic dysfunction. It is important for radiologists to be able to recognize the radiographic presentations of this rare disorder, as delay in diagnosis can lead to extensive and sometimes unnecessary workup. We present a case of congenital indifference to pain initially interpreted as a mass of the distal femur.
EARLY PREDICTORS OF RENAL DYSFUNCTION IN Β-THALASSEMIA MAJOR AND INTERMEDIA PATIENTS
Authors: Tantawy Azza A.G. , El Bablawy Nagham , Adly Amira A. M , Ebeid Fatma S E 
Published: September 2014

Background: Better survival of thalassemia patients allowed previously unrecognized renal complications to emerge. Objectives: Assess prevalence and early predictors of renal dysfunction in young β-thalassemia major (β-TM) and intermedia (β-TI) patients. Subjects: 66 β-TM (group I), 26 β-TI (group II) Egyptian patients and 40 healthy controls. Methods: History, examination and investigations that included kidney function tests, serum ferritin, serum bicarbonate, plasma osmolality and urinary total proteins, microalbuminuria (MAU), N-acetyl-β-D-glucosaminidase (NAG), retinol binding protein (RBP), α-1 microglobulin, bicarbonate, osmolality, Creatinine clearance (CrCl), % fractional excretion of bicarbonate (% FE-HCO3). Results: The most common renal abnormality was proteinuria (71%), followed by increased urinary level of RBP (69.4%), NAG (58.1%), α-1 microglobulin (54.8%) and microalbumin (29%) and also decreased urinary osmolality (58.1%). Although serum creatinine and BUN were not statistically different between thalassemia patients and control, CrCl were significantly lowered in thalassemia patients. Total serum protein and albumin was significant lower in splenectomized β-TM, whereas urinary total protein and MAU were significantly increased in all thalassemia patients. NAG, RBP and α-1 microglobulin were negatively correlated with CrCl and positively correlated with serum ferritin and urinary total protein. Z-score analysis for discrimination of patients with renal dysfunction proved superiority of urine total protein and RBP. Comparative statistics of different frequencies revealed significant difference between the urinary total protein and both MAU and % FE-HCO3. Conclusion: Asymptomatic renal dysfunctions are prevalent in young β-TM and β-TI patients that necessitate regular screening and urinary total protein and RBP may be cost-effective for early detection.
IS HEMOGLOBIN E GENE WIDELY SPREAD IN THE STATE OF MADHYA PRADESH IN CENTRAL INDIA? EVIDENCE FROM FIVE TYPICAL FAMILIES
Authors: Balgir R S 
Published: September 2014

Background: Red cell inherited hemoglobin anomalies are commonly encountered in the central region of India. These cause a public health concern due to high degree of morbidity, mortality, and fetal loss in the backward, underprivileged, and vulnerable people. Purpose: To report five typical families of hemoglobin E disorders identified for the first time in the state of Madhya Pradesh from central India. Methods: Out of a total of 445 couples/families (excluding the present study) with 1526 persons (848 males and 678 females) referred from a tertiary hospital in central India for investigations of anemia/hemoglobinopathies during the period from March 2010 to February 2014, we came across five typical rare couples/families of hemoglobin E disorders worthy of detailed investigations. Laboratory investigations were carried out following the standard procedures after cross checking for quality control from time to time. Results: For the first time, we have encountered nine cases of heterozygous hemoglobin E trait, two members with hemoglobin E-β-thalassemia (double heterozygosity), two cases of sickle cell-hemoglobin E disease (double heterozygosity), and none with homozygous hemoglobin E. Cases of hemoglobin E trait, hemoglobin E-β-thalassemia, sickle cell-β-thalassemia and sickle cell-E disease showed moderate to severe anemia, and target cells, and reduced values of red cell indices like RBC, Hb level, HCT, MCV, MCH and MCHC, representing abnormal hematological profile and clinical manifestations before blood transfusion. Conclusions: Double heterozygosity for hemoglobinopathies such as occurrence of β-thalassemia mutation with structurally abnormal hemoglobins (Hb S and Hb E) is a rare entity, but occurs with severe clinical manifestations only in those areas or communities where these are highly prevalent, testifying the migrations and genetic admixture. Distribution of hemoglobin E and β-thalassemia in different districts of Madhya Pradesh indicates that abnormal Hb E gene has wide spread and needs prevention for the rehabilitation of vulnerable people in central India.
