Evaluation of Different Methods for Determining the Entrance Pressure Drop in Capillary Rheometry
Authors: Aho Johanna , Syrjälä Seppo 
Published: June 2019

Abstract
Two approaches for determining the entrance pressure drop in capillary rheometry were compared with low-density polyethylene and polystyrene melts as test fluids. Direct measurements with the orifice die were found to yield higher values for the entrance pressure drop, and hence lower values for the wall shear stress, than the Bagley correction method. This was postulated to be caused by the sticking of the melt to the wall of the outlet region of the orifice die. The additional pressure drop created in the outlet region of the orifice die, when the flowing material fills it completely, was also evaluated by means of numerical flow simulation.

Published: June 2019

AbstractIntroductionThe prevalence of thyroid nodules is 4-7% in adults. Although less than 5% of nodules in adults are malignant, most nodules are non-neoplastic or benign. Fine needle aspiration (FNA) is a diagnostic technique for evaluation of non-toxic nodules, which has been widely accepted. Its primary objective is the patient triage in order to identify those who need surgery and aid in the decision of the appropriate surgical procedures.Materials and MethodsThis retrospective study was conducted on 116 patients who underwent thyroidectomy in Semnan’s Kowsar Hospital during 2011-2018 in Iran. The data were recorded before and after the surgery in the checklist. The data were compared and the sensitivity, specificity and diagnostic accuracy of FNA were calculated. Data were analyzed by SPSS software (version 18.0) and analyzed by Chi-Square test and Independent Samples test.ResultsThe sensitivity of FNA was 96.9%; its specificity was 81.7%; its positive predictive value (PPV) was 73.8%; its negative predictive value (NPV) was 98%; and its diagnostic accuracy was 86.9%.For the nodules smaller than 4 cm, FNA was calculated with higher sensitivity, specificity, PPV, NPV, and diagnostic accuracy compared to nodules larger than 4 cm.ConclusionFNA is a reliable screening method for preoperative assessment that can accurately detect malignant cases from benign cases, especially if the size of the nodule is smaller than 4 cm.
First insight into the phenolic content of Spartina maritima: isolation, characterization and quantification of four C-glycosidic flavonoids
Authors: Grignon-Dubois Micheline , Rezzonico Bernadette 
Published: June 2019

Abstract
The phenolic content of Spartina maritima was investigated using chromatographic and spectroscopic techniques. Aqueous methanolic extracts were prepared from plant collected in different seasons in the Bay of Arcachon (French Atlantic coast). High performance liquid chromatography (HPLC) with diode array detection (DAD) coupled with mass spectrometry allowed identification of four major phenolics in the aerial tissue, all belonging to the C-glycosidic-flavonoid class. They were isolated from the crude extracts, and their structures were assigned to isovitexin, isoscoparin and their respective 2″-O-glucosides on the basis of NMR, mass and UV spectroscopies. The seasonal variation of the flavonoid content was quantified over the period January 2013 to May 2015. The total concentration found ranged from 1.73 to 4.60 mg g−1 dry wt for isovitexin derivatives, and 0.88–2.66 mg g−1 dry wt for isoscoparin derivatives. The phenolic content of the rhizomes was very low and mainly dominated by coumaric acid (0.03–0.08 mg g−1), along with ferulic acid (≤0.06 mg g−1). The lack of significant concentrations of flavonoids in the rhizome contrasts with the aerial tissue. This work constitutes the first phenolic profiling of S. maritima and should provide a foundation for further studies, considering the reported biological activities of C-glycosidic flavonoids, and the lack of knowledge of the phenolic chemistry of the genus Spartina.

Cardiovascular risk factors in children with type 1 diabetes mellitus
Authors: Zhang Ying , Zhang Han , Li Pin 
Published: June 2019

Abstract

Objective
Cardiovascular disease is a major complication among children with type 1 diabetes mellitus (T1DM). This prospective study aimed at examining the presence of cardiovascular risk factors in children with T1DM.

Methods
We evaluated several cardiovascular risk factors, including atherosclerosis, artery intima-media thickness (IMT) and metabolic responses, in 175 children with T1DM, with 150 non-diabetic children as normal controls.

Results
The diabetic children had significantly higher carotid IMT (cIMT) and aortic IMT (aIMT), higher values for diastolic wall stress (DWS), incremental elastic modulus (IEM), and flow-mediated dilatation (FMD) than the controls. The levels of tumor necrosis factor-α (TNF-α), interleukin-4 (IL4), high-sensitivity C-reactive protein (hs-CRP) and leptin were significantly higher in T1DM patients. In T1DM children, the cIMT and aIMT were correlated with several risk factors, including age, weight, body mass index (BMI), duration of diabetes, waist/hip ratio, as well as levels of total cholesterol, triglycerides and apolipoprotein B (apoB). In addition to common risk factors, cIMT was also associated with systolic blood pressure (BP). Other risk factors, such as height, diastolic BP, low-density lipoprotein (LDL)/high-density lipoprotein (HDL)-cholesterol ratio, apolipoprotein A1 (apoA1) and S-creatinine levels, were not all independent risk factors of cardiovascular disease in T1DM children.

Conclusions
T1DM is associated with early impairment of the common carotid and aortic artery structure and function, and the diabetic state may be the main risk factor for arterial wall stiffening and thickening.
Short stature in a boy with atypical progeria syndrome due to LMNA c.433G>A [p.(Glu145Lys)]: apparent growth hormone deficiency but poor response to growth hormone therapy
Authors: Toni Ledjona , Dušátková Petra , Novotná Dana , Zemková Daniela , Průhová Štěpánka , Lebl Jan 
Published: June 2019

Abstract

Background
Hutchinson-Gilford progeria syndrome (HGPS) is a rare disease caused by pathogenic variants in the LMNA gene, which leads to premature aging. The median life expectancy is shortened to 13 years due to cardiovascular complications.

Case report
We present a boy born with a pathogenic LMNA variant c.433G > A, which causes atypical progeria syndrome (APS) and was previously described in one single patient. When investigated for poor growth prior to the diagnosis of APS, his laboratory tests revealed growth hormone (GH) deficiency and magnetic resonance imaging (MRI) of the midbrain showed partial empty sella. GH treatment had only a limited and transient effect. His first ischemic complication manifested at age 4.2 years; at the age of 7 years, he had a fatal haemorrhagic stroke.

Conclusion
To the best of our knowledge, this is the first patient with APS showing partial empty sella and GH deficiency that might have contributed to his poor growth. GH failed to improve long-term outcome.

Abstract
Two edible, cultivable mushroom species of the family Strophariaceae, Kuehneromyces mutabilis (sheathed woodtuft) and Hypholoma capnoides (conifer tuft), were studied using proton nuclear magnetic resonance metabolomic approach. The variation in the metabolites of the two species and their metabolic behaviour regarding caps and stipes and different collection sites were analysed by multivariate analysis methods. Altogether 169 cap and stipe samples of the mushrooms were investigated. The clearest difference between the species was in the sugar composition, which was more diverse in H. capnoides. When mushroom samples collected from different locations were compared, more variance was found in H. capnoides, whereas K. mutabilis appeared more homogeneous as a species. As far as the caps and stipes were concerned, in both species the amount of α-α-trehalose was clearly higher in the stipes, and the caps contained a larger proportion of the amino acids and organic acids.

Authors: Fouda Abd El-Aziz El-Sayed , Zaki El-Sayed Gmal , Khalifa Mohamed Ahmed 
Published: June 2019

AbstractSome surfactants were synthesized, its chemical structures were checked using Fourier transform infrared spectroscopic (FT-IR). The investigation of inhibition efficiency (IE%) for dissolution of (LCS) in 1.0 M HCl with and without various concentrations of these compounds were done using electrochemical and non-electrochemical methods. Measured data depends on temperature, concentration, and nature of the substance. These compounds were adsorbed on LCS surface following Temkin isotherm. Polarization studies illustrated that these surfactants act as mixed inhibitors (anodic and cathodic). The effect of these inhibitors on LCS surface morphology’s was detected by Scanning Electron Microscope (SEM), ATR-IR (Attenuated total reflection Infra-red) and Atomic Force Microscopy (AFM) techniques. The parameters in an activated state of LCS were studied and estimated. All data techniques were compatible and matched.
Towards Design of Quasilinear Gurvits Control Systems
Authors: Gaiduk Anatoly 
Published: June 2019

The design problem of control systems for nonlinear plants with differentiated nonlinearity is considered. The urgency of this problem is caused by the big difficulties of practical design of nonlinear control systems with the help of the majority of known methods. In many cases, even provision by these methods of just stability of equilibrium point of a designing system represents a big challenge. Distinctive feature of the method of nonlinear control systems design considered below is the use of the nonlinear plants models represented in a quasilinear form. This form of the nonlinear differential equations exists, if nonlinearities in their right parts are differentiated across all arguments. The quasilinear model of the controlled plant allows reducing the design problem to the solution of an algebraic equations system, which has the unique solution if the plant is controlled according to the controllability condition provided in the article. This condition is similar to the controllability condition of the Kalman’s criterion. Procedure of the nonlinear control systems design on a basis of the plant’s quasilinear models is very simple. Practically, it is close to the known polynomial method of the linear control systems design. The equations of the nonlinear systems designed with application of the plant’s quasilinear models also can be represented in the quasilinear form.
The basic result of this article is the proof of the theorem and the corollary from it about conditions of the asymptotical stability at whole of the equilibrium point of the nonlinear control systems designed on a basis of the plant’s quasilinear models. For the proof of the theorem and consequence, the properties of simple matrixes and known theorems of stability of the indignant systems of the differential equations are used. A way of the stability research of the equilibrium point of the quasilinear control systems based on the proved theorem is illustrated by numerical examples. Computer simulation of these systems verifies correctness of the hypoyhesis of the proved theorem.
Obtained results allow applying the method of nonlinear systems design on a basis of the quasilinear models for creation of various control systems for plants in power, aviation, space, robotechnical and other industries.

Aim. To determine the effect of Leu-Ile-Lys tripeptide on indicators of oxidative stress and expression of cyclooxygenase-1 and -2 in the gastric mucosa on the background of experimental indomethacin-induced ulcer.
Methods. Experiments were performed on 35 male Wistar rats with a body mass of 200-250 g aged 2-3 months that were divided into 3 groups: the control group (intact rats, 8 animals), control group (simulation of indomethacin-induced gastropathy, 12 animals) experimental group (simulation of indomethacin-induced gastropathy + administration of Leu-Ile-Lys tripeptide, 15 animals). The tripeptide Leu-Ile-Lys obtained by chemical synthesis (sample purity at least 98%) was administered intragastrically daily for 7 days before the simulation of indomethacin-induced damage of the gastric mucosa in a dose of 11.5 mg/kg. The model of indomethacin-induced damage to the rodent gastric mucosa was reproduced by a single intragastric administration of indomethacin in a dose of 60 mg/kg in 1 ml of saline. In the stomach homogenate the activity of free radical oxidation was determined by conventional methods. For quantitative determination of cyclooxygenase-1, -2 in gastric homogenate the method of enzyme immunoassay was used. The concentration was determined spectrometrically by the color intensity of the samples.
Results. With a prophylactic administration of tripeptide Leu-Ile-Lys, concentration of tiobarbiturate-reactive products was normalized, total antioxidant activity increased and the activity of antioxidant enzymes decreased compared to the control group. The concentration of cyclooxygenase-2 in gastric homogenate from the experimental animals was 2.3 times lower than that of the control rats.
Conclusion. Use of Leu-Ile-Lys tripeptide in experimental indomethacin-induced gastric ulcer showed a significant decrease of oxidative damage and inflammation in the gastric mucosa.

Published: June 2019

Aim. To present a clinical case of treatment of pigment dispersion syndrome by clear lens extraction and implantation of a toric intraocular lens in a patient with myopic astigmatism.
Methods. A 33-year-old patient with a diagnosis of moderate myopia, complex mild myopic astigmatism, pigment dispersion syndrome of both eyes.
Results. The first stage was laser peripheral iridotomy of both eyes. On follow-up pathological irido-zonular contact and increases intraocular pressure by 2 mm persisted. The second stage included clear lens extraction and implantation of a toric multifocal intraocular lens to both eyes. In 2 months, distance and near visual acuity was 1.0, intraocular pressure was normal, no pathological irido-zonular contact was observed according to the ultrasound biomicroscopy.
Conclusion. Implantation of an intraocular lens in patients with myopia and pigment dispersion syndrome is both a method of preventing pigment glaucoma and myopia correction; patients with pigment dispersion syndrome after peripheral iridotomy should monitor the state of the anterior segment of the eye and the effectiveness of the treatment by ultrasound biomicroscopy.
Realistyczna interpretacja domniemanego idealizmu G. Berkeleya

Filozof słusznie zwrócił uwagę na nieodzowność podmiotowych ujęć w kwestii dostępu do świata.

Le concept du fragmentaire dans le <em>Journal</em> d’Henriette Dessaulles
Authors: Vadean Mirella 
Published: June 2019

Cet article met en évidence l’importance de l’analyse heuristique du fragment, fonction d’une esthétique représentative du continuum. Inclassable dans le cadre d’un genre, le fragment entretient une relation de dépendance et d’indépendance avec le Système (le Tout). En opérant une distinction entre la discontinuité et le fragment, nous saisissons dans le Journal d’Henriette Dessaulles une « exigence de la parole fragmentaire » nécessaire pour composer à partir du Décomposé et pour admettre à partir du Refus. Notre réflexion est articulée autour de deux axes : les obstacles du fragmentaire et le fragment comme praxis intentionnelle.AbstractThis paper emphasizes the importance of the heuristic analysis of the fragment as a function of an aesthetic representative of the continuum. Impossible to be classified as a type, the fragment maintains both a relationship of dependence and independence with the System (The Whole). By making a distinction between discontinuity and the fragment, we observe in the Henriette Dessaulles’ diary a "requirement of the fragmentary speech" which is necessary to compose starting from Decomposed and to admit starting from the Refusal. We organize our interpretation according to two axes: the obstacles of the fragmentary and the fragment as intentional praxis.
<em>L’Afrique</em> de Pétrarque et la bataille des lettres à la Renaissance
Authors: Bouchard Mawy 
Published: June 2019

On propose ici une réflexion sur la nature du travail poétique de Pétrarque dans son poème narratif L’Afrique, resté inachevé. À travers les voix de grands guerriers et de poètes qui en ont assuré la gloire, Pétrarque expose en effet sa conception de la narration digne de traverser les siècles en des termes qui ne correspondent pas tout à fait aux balises esthétiques de la poétique. Le grand poète toscan développe plutôt une éthique de l’écriture qui accorde la plus grande légitimité à la poésie « vraie ». Au fil des livres de L’Afrique, la prépondérance des lettres en général et de la poésie en particulier sur les autres compétences humaines constitue un leitmotiv qui allait devenir emblématique de la renaissance des lettres européennes.AbstractThis paper examines the poetics of Petrarca’s unfinished epic Africa. Through the voices of two great warriors and those of poets who have sung their praises, Petrarca exposes his conception of the worthy — that is the ethical — narrative. Indeed, the Tuscan poet develops an ethics of writing and strives to institute a poetry of ‘truth’. Throughout Africa, the preponderance of letters in general and of poetry in particular constitutes a leitmotiv that was to become emblematic of Renaissance literature.
Rachilde : Une décadente dans un réseau de bas-bleus
Authors: Finn Michael 
Published: June 2019

Il peut paraître surprenant que l’écrivaine décadente Rachilde, connue pour ses provocations et le scandaleux Monsieur Vénus, ait fait partie d’un réseau de bas-bleus formé de femmes à la fois plus vieilles et plus conservatrices qu’elle. La journaliste Camille Delaville défend Rachilde dans la presse et lui ouvre les colonnes de son journal Le Passant, alors que Georges de Peyrebrune, quoiqu’elle critique Rachilde dans son roman à clefs Une décadente, lui sert de confidente pendant plus de vingt ans. Malgré leurs différences, ce qui a joué dans cette relation triangulaire, c’est un certain féminisme qui reconnaît que les relations d’amitié entre femmes sont plus loyales que celles avec les hommes, trop souvent compliquées sinon compromises par la sexualité.AbstractThe decadent writer Rachilde, known for her provocative behaviour and her novel of depravation Monsieur Vénus, was, surprisingly, a member of a network of older, conservative bluestockings. The journalist Camille Delaville defended Rachilde in the press and invited her collaboration in her newspaper Le Passant, while the novelist Georges de Peyrebrune, though critical of Rachilde’s eccentricities in Une décadente (a roman à clefs), served as a maternal confidante for more than 20 years. What linked these three writers was a feminist sense that relations of friendship between women are more loyal that those with men, the latter too often complicated and compromised by sexual questions.
Gaétane de Montreuil, conseillère, bibliothécaire, professeure, critique, éditrice, publicitaire

Published: June 2019

La trajectoire de la journaliste Gaétane de Montreuil (1867-1951), chroniqueuse à La Presse (1898-1903), romancière, poète, nouvelliste puis directrice du périodique féminin Pour vous mesdames (1913-1915), offre une perspective privilégiée sur l’évolution des stratégies discursives des femmes de lettres suivant les différentes tribunes médiatiques qu’elles occupent. Au sein d’un champ littéraire canadien-français où la littérature ne se dégage pas encore de l’ensemble de l’espace social et où la critique littéraire est encore embryonnaire, Gaétane de Montreuil agit tour à tour comme conseillère, bibliothécaire, professeure, critique, éditrice et publicitaire. Ce cumul des rôles littéraires féminins, particulièrement denses, marque une étape significative dans l’émergence d’une expertise littéraire au féminin à la fin du XIXe siècle.AbstractAlternately columnist at La Presse (1898-1903), novelist, poet, short story writer, and as the director of women’s magazine Pour vous mesdames (1913-1915), the prolific career of Gaétane de Montreuil (1867-1951) offers a singular perspective on discursive strategies used by women writers, and their evolution according to the literary standpoint, at the turn of the twentieth century. In the context of a literary field still strongly linked to the more general social space, and when literary critique is still embryonic, Gaétane de Montreuil plays different roles: counsellor, librarian, teacher, critique, editor, advertising executive, etc. This plurality is important and significant, particularly in the context of women’s literary practices, at a moment when a feminine literary expertise emerges in the French Canadian context.
