The Relationship between Resilience and Distress Tolerance in College Students: The Mediator Role of Cognitive Flexibility and Difficulties in Emotion Regulation
Authors: Arici-Ozcan Neslihan , Cekici Ferah , Arslan Reyhan
Published: September 2019

The purpose of this study is to examine the mediator role of cognitive flexibility and difficulties in emotion regulation in the relationship between resilience and distress tolerance amongst college students. The sample of the study involved 1114 students (771 females, 343 males) from various universities in Turkey. The mean age of the sample was 20.65 (Sd=2.77). The Resilience Scale, Distress Tolerance Scale, Cognitive Flexibility Scale, and Difficulties in Emotion Regulation Scale (DERS) had been used to collect data. In this study, a Serial Multiple Mediation Model was used, as proposed by Hayes. The findings showed that people with a higher level of distress tolerance possess higher degrees of cognitive flexibility and that cognitively more flexible individuals experience less difficulty in emotion regulation, and thus, lower levels of difficulty in emotion regulation were associated with an increase in resilience. Furthermore, the model in its entirety had proven to be statistically significant, accounting for 42% of the total variance.
Postoperative weightbearing following ankle arthrodesis
Authors: Potter Matt J. , Freeman Richard
Published: September 2019

Aims

Postoperative rehabilitation regimens following ankle arthrodesis vary considerably. A systematic review was conducted to determine the evidence for weightbearing recommendations following ankle arthrodesis, and to compare outcomes between different regimens.

Patients and Methods

MEDLINE, Web of Science, Embase, and Scopus databases were searched for studies reporting outcomes following ankle arthrodesis, in which standardized postoperative rehabilitation regimens were employed. Eligible studies were grouped according to duration of postoperative nonweightbearing: zero to one weeks (group A), two to three weeks (group B), four to five weeks (group C), or six weeks or more (group D). Outcome data were pooled and compared between groups. Outcomes analyzed included union rates, time to union, clinical scores, and complication rates.

Results

A total of 60 studies (2426 ankles) were included. Mean union rates for groups A to D were 93.2%, 95.5%, 93.0%, and 93.0%, respectively. Mean time to union was 10.4 weeks, 14.5 weeks, 12.4 weeks, and 14.4 weeks for groups A to D, respectively. Mean complication rates were 22.3%, 23.0%, 27.1%, and 28.7% for groups A to D, respectively. Reporting of outcome scores was insufficient to conduct meaningful analysis.

Conclusion

Outcomes following ankle arthrodesis appear to be similar regardless of the duration of postoperative nonweightbearing, although the existing literature is insufficient to make definitive conclusions. Cite this article: Bone Joint J 2019;101-B:1256–1262

Published: September 2019

Aims

Currently, periprosthetic fractures are excluded from the American Society for Bone and Mineral Research (ASBMR) definition of atypical femoral fracture (AFFs). This study aims to report on a series of periprosthetic femoral fractures (PFFs) that otherwise meet the criteria for AFFs. Secondary aims were to identify predictors of periprosthetic atypical femoral fractures (PAFFs) and quantify the complications of treatment.

Patients and Methods

This was a retrospective case control study of consecutive patients with periprosthetic femoral fractures between 2007 and 2017. Two observers identified 16 PAFF cases (mean age 73.9 years (44 to 88), 14 female patients) and 17 typical periprosthetic fractures in patients on bisphosphonate therapy as controls (mean age 80.7 years (60 to 86, 13 female patients). Univariate and multivariate analysis was performed to identify predictors of PAFF. Management and complications were recorded.

Results

Interobserver agreement for the PAFF classification was excellent (kappa = 0.944; p < 0.001). On univariate analysis compared with controls, patients with PAFFs had higher mean body mass indices (28.6 kg/m2 (sd 8.9) vs 21.5 kg/m2 (sd 3.3); p = 0.009), longer durations of bisphosphonate therapy (median 5.5 years (IQR 3.2 to 10.6) vs 2.4 years (IQR 1.0 to 6.4); p = 0.04), and were less likely to be on alendronate (50% vs 94%; p = 0.02) with an indication of secondary osteoporosis (19% vs 0%; p = 0.049). Duration of bisphosphonate therapy was an independent predictor of PAFF on multivariate analysis (R2 = 0.733; p = 0.05). Following primary fracture management, complication rates were higher in PAFFs (9/16, 56%) than controls (5/17, 29%; p = 0.178) with a relative risk of any complication following PAFF of 1.71 (95% confidence interval (CI) 0.77 to 3.8) and of reoperation 2.56 (95% CI 1.3 to 5.2).

Conclusion

AFFs do occur in association with prostheses. Longer duration of bisphosphonate therapy is an independent predictor of PAFF. Complication rates are higher following PAFFs compared with typical PFFs, particularly of reoperation and infection. Cite this article: Bone Joint J 2019;101-B:1285–1291

Published: September 2019

BACKGROUND

Despite implementation of the Athlete Biological Passport 10 years ago, blood doping remains difficult to detect. Thus, there is a need for new biomarkers to increase the sensitivity of the adaptive model. Transcriptomic biomarkers originating from immature reticulocytes may be reliable indicators of blood manipulations. Furthermore, the use of dried blood spots (DBSs) for antidoping purposes constitutes a complementary approach to venous blood collection. Here, we developed a method of quantifying the RNA-based 5′-aminolevulinate synthase 2 (ALAS2) biomarker in DBS.

MATERIALS

The technical, interindividual, and intraindividual variabilities of the method, and the effects of storage conditions on the production levels of ALAS2 RNA were assessed. The method was used to monitor erythropoiesis stimulated endogenously (blood withdrawal) or exogenously (injection of recombinant human erythropoietin).

RESULTS

When measured over a 7-week period, the intra- and interindividual variabilities of ALAS2 expression in DBS were 12.5%–42.4% and 49%, respectively. Following withdrawal of 1 unit of blood, the ALAS2 RNA in DBS increased significantly for up to 15 days. Variations in the expression level of this biomarker in DBS samples were more marked than those of the conventional hematological parameters, reticulocyte percentage and immature reticulocyte fraction. After exogenous stimulation of erythropoiesis via recombinant human erythropoietin injection, ALAS2 expression in DBS increased by a mean 8-fold.

CONCLUSIONS

Monitoring of transcriptomic biomarkers in DBS could complement the measurement of hematological parameters in the Athlete Biological Passport and aid the detection of blood manipulations.

In Unmade, Untitled, my practice as research project, the sense of un/belonging – a feeling of dislocation paired with the notion of impossible homecomings – is transferred in affective and embodied ways to audience participants. This article outlines the methods that Unmade uses to create memory spaces to comment on the complexities of migratory belongings in an age of global migration. This is done by introducing disruptive material metaphors into ritualistic food-making, and requesting the performance of surrogate speakers from participants who re-voice an autobiographical narrative.
Writing a short story, the preclosural way
Authors: Powell Dan
Published: October 2019

This article examines how preclosure theory and the data gathered from preclosural analysis might be used to support creative writing. Preclosure theory attempts to reveal how and why readers chunk short stories into ‘meaningful units above the sentence level’ (Lohafer 2003: 58) through identification and analysis, both structural and linguistic, of those sentences in a narrative where a reader feels the story could end. This article begins with a description of the development of a preclosural writing frame for the creation of short fiction, explaining how the writing frame itself is developed in response to data generated by the preclosural analysis of fifteen British short stories written between 1885 and 1920. Here I propose that this methodology offers the author-practitioner a new way of controlling the staging of closure within a short story by replacing a previously intuitive process with a more conscious approach. In the article’s second half, I describe my writing process prior to my engaging with preclosure theory. This account of my intuitive and unconscious manipulation of closural staging in prior works provides context for an evaluation of the impact of this methodology upon both my writing process and the text produced. In closing, I argue that the preclosural writing process outlined here has had a positive effect upon my own practice and, furthermore, has the potential to extend the author-practitioner’s understanding of and ability to innovatively employ the staging of closure when crafting a short story.

Published: September 2019

To investigate the behaviour of doxycycline hyclate in water, aqueous glycine and aqueous L-alanine solutions, the viscometric and conductometric studies have been conducted at different temperatures. Viscosity data has been used to derive the Jones-Dole viscosity B-coefficient, temperature derivative of B-coefficient (dB/dT), viscosity B-coefficient of transfer (ΔtrB), free energy of activation of viscous flow per mole of solvent (Δμ1 o*) and solute (Δμ2o*) respectively, activation entropy (ΔS2o*) and activation
enthalpy (ΔH2o*). Conductance data has been used to compute Walden product (Λm
oηo) and temperature coefficient of Walden product (dΛmoηo/dT) for doxycycline hyclate in water, and in aqueous glycine and aqueous L-alanine solution. The positive values of B-coefficient, ΔtrB indicate the prevailing of hydrophilic-ionic interactions in the systems under examination. The negative values of dB/dT and positive values of temperature coefficient of Walden product infer structure maker tendency of doxycycline hyclate in water, and in aqueous glycine and aqueous L-alanine solution. Transfer energy parameters indicate the breaking of intermolecular bonds in transition state which means that formation of activated complex is unfavourable

A comparative Study on Polymorphism of Commercial Ranitidine Hydrochloride Drug Samples in India
Authors: Bijudas K. , Bashpa P.
Published: October 2019

Ranitidine hydrochloride is a drug used to treat stomach acid production. It is commonly advised in the treatment of peptic ulcer and gastrophaegal reflux. Ranitidine hydrochloride exists in two different polymorphic forms, namely form I and form II. Various brands of ranitidine hydrochloride tablets manufactured by different pharmaceutical companies in India were collected, finely powdered and recrystallized from ethanol water mixture. The melting points of pure drug samples were determined to assess the polymorphic form present in each sample. All the pure drug samples showed a melting point in the range 135 to 138 °C and prove the existence of polymorph form I. The pure recrystallized drug samples were kept at room temperature for about 60 days in order to study the changes in polymorphic form if any and found fairly stable on prolonged storage. Infrared and UV-visible spectral studies have been carried out by taking Zinetac 150 mg (GlaxoSmithKline Pharmaceuticals Ltd., Mumbai) as the standard in order to prove the chemical constitution of the drug.
Combination of Sjogren’s disease with autoimmune thyroiditis: A case history
Authors: Sycheva Ye A , Khein Ts S
Published: October 2019

Therapists, including rheumatologists, often forget that many autoimmune diseases are combined with endocrine pathology, in particular with thyroid pathology.

These cases, according to the classification of N. Smith and A. Steinberg, belong to the 5th class - class E of autoimmune diseases, which includes conditions that manifest several autoimmune diseases, both organ-specific and organ-specific.

In the literature, cases of combinations of endocrine diseases with non-endocrine autoimmune are described. It was noted that they are most often found in young women, which are associated with the X chromosome.

We give our own observation of a patient with Sjogren's disease in combination with thyroid pathology.

The paper presents the results of treatment in 45 adult patients with somatotropic insufficiency. The study was undertaken to compare the efficiency of treatment of the patients with different doses of the human growth hormone Humatrop and to evaluate its safety. The treatment lasted 6 months. Within the first 3 months, Group 1 patients (n = 24) received Humatrop in a dose of 3.0 pg/kg/day, Group 2 patients (n = 24) had its dose of 6.0 pg/kg/day. Later on the dose was doubled in both groups. The criteria for therapeutic efficiency were changes in the body’s structure (LBM, FM), insulin-like growth factor 1 (IGF-1), and IGF-binding protein-3. In both groups, there was an increase in lean body mass (p < 0.001 in Group 1 and p < 0.018 in Group 2) and a decrease in fatty body mass (p — 0.005 and p < 0.001, respectively) by the end of treatment. The levels of IGF-1 and IGF-binding protein-3 were higher just by the end of the third month of treatment (p < 0.001). There were group differences in all the indices of therapeutic efficiency throughout the treatment period. Side effects were slightly more frequently observed in Group 2 patients. The findings allow Humatrop to be recommended in a dose 3 pg/kg/day within the first 3 months of treatment since the dose is as effective as the larger dose (6 pg/kg/day). Further, the dose of the agent should be changed on an individual basis depending on the levels of IGF-1 and the presence of adverse reactions.

Authors: Dreval A V , Kovachev B P , Starostina E G , Misnikova I V , Dreval O. A
Published: September 2019

The study included 18 patients (10 females and 8 males) with a not less than 2 year-history of type 1 diabetes (T1D), who had received insulin therapy since its diagnosis was established. The patients ’ mean age was 32.9± 13.0 years; the mean duration of TID was 15.1+11.5 years; the mean daily dose of insulin was 40.1+16.0 units; the mean level of glycosylated hemoglobin (HbAJ was 9.4±2.1% (the normal value 4.4-4.9%).

The glycemic curve symmetrization method proposed for statistical analysis of glycemic self-control is also quite suitable for the statistical monitoring of a continuous daily glycemic curve.

The high and low glycemic indices calculated from the symmetrized glycemic data correlate well with the level of HbAk and with the duration of hypoglycemia and hyperglycemia and hence they may be used as additional criteria for a risk of diabetes complications. The criteria, calculated from the symmetrized data of glycemia for the risk of hyper- and hypoglycemia, adequately reflect the behavior of a continuous glycemic curve and may be used as integral indices of the efficiency of glucose-reducing therapy in clinical practice.

O objetivo deste artigo é analisar a fragmentação da paisagem e sua evolução temporal considerando um intervalo de 25 anos (1990 e 2015) para a região metropolitana de Aracaju, Sergipe, Brasil. Como materiais foram utilizadas imagens de satélites LANDSAT 5 e 8. As imagens foram classificadas pelo método supervisionado conforme a seleção de sete classes de uso do solo, sendo elas: Floresta, Mangue, Restinga, Cultivo e/ou Pastagem, Solo Exposto, Adensamento Urbano e Corpos D’Água. A validação das classificações foi feita através da análise da matriz de confusão e do cálculo do índice Kappa. A partir desta classificação, foram calculadas sete métricas à nível de fragmento (área total da classe, porcentagem da classe na paisagem, número de fragmentos por classe, densidade de fragmentos, tamanho médio do fragmento por classe, índice de proximidade médio, distância média até o vizinho mais próximo). Os resultados obtidos indicam que a área de estudo se encontra com transformações estruturais da paisagem desde 1990 e apresenta alto grau de fragmentação das áreas de vegetação natural (Floresta, Mangue e Restinga) sendo sobrepostas por classes relacionadas ao uso antrópico, principalmente no que diz respeito ao uso urbano e às atividades agropastoris.

Authors: Di Prospero Carolina
Published: October 2019

El objeto de estudio en este trabajo es el Live Coding, expresión musical digital desarrollada por un colectivo artistas computacionales, programando música en vivo. El live coder como programador artista, dialoga en un ida y vuelta con el lenguaje de programación que utiliza en sus performances, a través de la manipulación de los códigos en vivo (on the fly). En ese diálogo se produce la intervención imaginativa que los constituye como live coders: híbrido lenguaje–artista constituido en el momento de la improvisación. La intención exploratoria y experiencial caracteriza esta práctica tecnoartística. El artista y el software se hacen uno, se confunden, y los códigos tipeados en ese aquí y ahora se proyectan sobre el cuerpo del live coder, quien los porta como una máscara que los cubre durante toda la performance. En este artículo se aborda la subjetividad live coder: como artista computacional, como agente activo que subsume varios roles en una misma persona buscando eliminar las barreras entre quienes crean los lenguajes de programación y quienes ejecutan la música. Asímismo se analizará cómo a partir de la improvisación de la música algorítmica, los live coders construyen tanto su expresión artística como su autocomprensión como programadores artistas.
REGENERACIONISTAS, GUBERNISTAS, DISIDENTES Y REFORMISTAS COMBATEN EN EL RADICALISMO. SANTA FE, 1910–1916
Authors: Carrizo Bernardo
Published: October 2019

Este artículo propone analizar la experiencia política de la Unión Cívica Radical de Santa Fe (UCRSF) en la provincia homónima, en el lapso que media aproximadamente entre 1910 y 1916. La enriquecedora variación de escalas de análisis —lo local, lo provincial y lo nacional, que a su vez conforman diversos territorios de la política— permite la comprensión de fenómenos que se centran en una indagación sobre la Unión Cívica Radical (UCR) como partido nacional. Pero detener la mirada en un espacio provincial en articulación con las culturas políticas, permite analizar a «los radicalismos» que protagonizaron los primeros tramos de la democratización, y que aspiraban a la regeneración de la política. En este marco, una hipótesis que ordena el trabajo se orienta hacia los lazos que unieron y, al mismo tiempo, tensionaron a los radicales hasta el extremo de que el adversario, a través del discurso político, era presentado y definido como ilegítimo. Y en esta clave, se instala la pregunta sobre cuál ha sido la impronta que esa idea de ilegitimidad respecto del adversario ha dejado en la cultura política argentina.

Published: October 2019

Silica gel (SG) is one of common adsorbent on solid phase extraction for preconcentration. Due to the low selectivity and effectiveness of adsorption to metal ions, SG should be modified. The SG was modified with d-glycine (Si-Gly) using 3-aminopropyltrimethoxysilane and glutaraldehyde as a crosslinker. Capability of Si-Gly as adsorbent for cadmium ions (Cd) was investigated using batch adsorption. The result was proved by infrared spectra. The optimum condition of Cd adsorption by the Si-Gly was obtained at pH 5, with 0.3 g of adsorbent and 11 minutes of contact time. The percentage of Cd adsorption at the optimum condition by the Si-Gly (99.34%) which is greater than the SG (89.03%). The maximum adsorption capacity of the Si-Gly is 9.77 mg/g, obtained at 400 mg/L. The Cd(II) adsorption on the SG and the Si-Gly follow the Langmuir isotherm equation.
A Study on Photo-Fenton Method for Simulatenous and Synergic Decreasing Concentration of Pb(II) and Cu(II) in the Solution
Authors: Wahyuni Endang Tri , Supraba Dewi , Raharjo Sigit , Siswanta Dwi
Published: October 2019

To prevent an environmental pollution by hazardous heavy metals, in the present study, a simulatenous decrease of the concentration of Pb((II) and Cu(II) in the solution by photo-Fenton method has been systematically studied. Photo-Fenton process proceeded in a close reactor by batch technique. The process was conducted by exposure solutions containing Pb(II) and Cu(II) ions, and Fenton’s reagent (Fe2+ and H2O2) under UV-A lamp. In this study, the initial concentations of Pb(II) and Cu(II), and the exposure time were optimized. The synergyc effect that may be appeared on the decrease of Pb(II) and Cu(II) ion concentrations simultaneously through photo-Fenton process was also addressed. The concentrations of Pb(II) and Cu(II) in the solution were determined by AAS. The research results exhibited that photo-Fenton process could decrease Pb(II) and Cu(II) concentrations, and the maximum decreases, 46.12 % dan 16.86% for Pb(II) and for Cu(II) respecticely, were found by applying both initial concentration of Pb(II) and Cu(II) as much 35 mg/L, and 60 min of the time. The concentration decreases of Pb (II) and Cu(II) were results of oxidation by OH and by electron to form PbO2 and Cu particles respectively as probed by EDX data. Furthermore, photo-Fenton process toward a solution containing Pb(II) and Cu(II) ions allowed oxidation of Pb(II) and reduction of Cu(II) simultaneously and showed a synergic effect. Such effect was demonstrated by the fact that the presence of Cu(II) ion in the photo-Fenton process of Pb(II) solution could improve the Pb(II) oxidation and the highest improvement of Pb(II) oxidation (81.06%) was shown by 35 mg/L of the Cu(II) concentration. Similarly, the presence of Pb(II) in the photo-Fenton process of Cu(II) solution could enhance the reduction of Cu(II), and the highest effect on the Cu(II) reduction enhancement was exhibited by 35 mg/L of the Pb(II) concentration.

Antioxidants are compounds that can inhibit oxidation reactions by binding to free radicals and highly reactive molecules. One form of reactive oxygen compounds is free radicals, these compounds are formed in the body and are triggered by various factors. Noni fruits have been used by the community as a medicine for high blood pressure, beriberi, urinating, inflammation of bile, inflammation of the intestine, dysentery, constipation, spleen pain, liver pain, diabetes and lumbago. Nevertheless, research on the identification of the active compounds of noni fruit which act as antioxidants yet. This study aims to extract and fractionation of Noni fruit, determine the antioxidant activity of Noni fruit extract, and identify the types of bioactive compounds that act as antioxidants. Noni fruit was extracted used maceration technique with 96% ethanol and then fractionated using n-hexane, chloroform and ethyl acetate solvents. Antioxidant activity from the results of noni fruit fractionation was measured by the DPPH (1.1 diphenyl-2-picrylhydrachyl) method and identification of bioactive compounds was carried out by GCMS. The results showed the greatest antioxidant activity was found in chloroform fraction with a percentage of inhibition of 78.19%. For the first time this study revealed the types of bioactive compounds from noni fruit ethyl acetate fraction which act as antioxidants are n-hexadecanoic acid, squalene, pyridin-3-carboxamide, oxime, n- (2-trifluoro methyl phenyl), and beta-sitosterol
Framing Solidarity. Feminist Patriots Opposing the Far Right in Contemporary Poland
Authors: Ramme Jennifer
Published: October 2019

Due to the attempts to restrict the abortion law in Poland in 2016, we could observe a new broad-based feminist movement emerge. This successful movement became known worldwide through the Black Protests and the massive Polish Women’s Strike that took place in October 2016. While this new movement is impressive in its scope and can be described as one of the most successful opposition movements to the ethno-nationalist right wing and fundamentalist Catholicism, it also deploys a patriotic rhetoric and makes use of national symbols and categories of belonging. Feminism and nationalism in Poland are usually described as in opposition, although that relationship is much more complex and changing. Over decades, a general shift towards right-wing nationalism in Poland has occurred, which, in various ways, has also affected feminist actors and (counter)discourses. It seems that patriotism is used to combat nationalism, which has proved to be a successful strategy. Taking the example of feminist mobilizations and movements in Poland, this paper discusses the (im)possible link between patriotism, nationalism and feminism in order to ask what it means for feminist politics and female solidarity when belonging is framed in different ways.
Of Stereoscopes and Instagram: Materiality, Affect, and the Senses from Analog to Digital Photography
Authors: Fackler Katharina
Published: October 2019

This article addresses popular claims that photography has been “dematerialized” in the digital era. It engages a wide range of critical writings about photography from the early 19th to the 21st century to demonstrate that different versions of these claims have always formed an important part of photography criticism. However, rather than doing justice to photographs’ materiality or their complex entanglements with what has been considered material and immaterial, human and nonhuman, they have tended to somewhat limit our understanding of the medium’s material, sensory, and affective valences. This article argues that a sustained engagement between visual culture studies, sensory studies, and the new materialisms can help us understand more fully both analog and digital photography’s contingent position within the material world, varying sensory ideologies, and different subjectivities.

Background and aims. Localized gingival recession presents as a special therapeutic problem. Subjective parameters and donor site morbidity are often overlooked while deciding on any treatment option. Materials and methods. 22 subjects were equally divided in Group A (Lateral pedicle graft) and Group B (Free mucosal graft). Subjective evaluation of post operative sensitivity, discomfort and bleeding at donor site, and patient perception of aesthetics was done. Results. Both groups showed the potential of achieving root coverage; however on comparison between the two groups, lateral pedicle flap showed improved patient perceived Quality of Life as compared to free mucosal graft, although clinical results were statistically non significant. Conclusion. Lateral pedicle graft is associated with less donor tissue morbidity and is well tolerated by the patient as compared to free mucosal graft.

Background and aims. The aim of this study was to compare the biocompatibility of calcium-enriched mixture cement (CEM), composite resin and nano-particled mineral trioxide aggregate (NP-MTA) using human gingival fibroblasts. Materials and methods. A comparative in vitro cell culture study was carried out using 60 single-rooted teeth which were assigned to the following four groups: 1) untreated healthy group (control); 2) restored with composite resin; 3) CEM cement; 4) NP-MTA. The MTT assay was used to measure the viability of fibroblasts attached to each specimen and scanning electron microscopy (SEM) was used for describing cell morphology. Results. After 24 hours of incubation, the survival rates for composite resin and NP-MTA were 74.1% and 76.9%, respectively, which were significantly lower than the value in the control group, while both were equally biocompatible. No statistically significant difference was found between the control group and CEM cement samples (94.3%). After 3 days of incubation, some increases in the viability of fibroblasts were detected in the composite resin and NP-MTA groups, with their survival rates being 89% and 93%, respectively. Conversely, in the CEM cement group, the survival rate decreased to 80.7%, which was significantly lower than that in the control group (P = 0.0001). Conclusion. The results of in vitro tests indicated that on days 1, 3 and 5 after incubation, composite resin, CEM cement and NP-MTA exhibited acceptable biocompatibility, provided they were allowed to set for 24 hours before exposure to the cells.
Surgical reconstruction of lost papilla around implant with a modified technique: A case report
Authors: Faraji Mahdi , Zyl Andre Van
Published: October 2019

This case report describes the clinical application of the coronally advanced flap procedure associated with the subepithelial connective tissue pedicle graft with palatal tunneling for the reconstruction of interproximal papillae. In this modified technique the distal end of the pedicle graft was divided into two parts, creating a bifid, which were then placed around the abutment and sutured on the facial aspect. This technique resulted in the filling up of the entire black triangle, coverage of gingival recessions on adjacent teeth, a significant improvement in the emergence profile of the implant-supported restoration, and obvious esthetic improvement
Comparative evaluation of coronally positioned flap with or without using a collagen barrier membrane for root coverage procedures: A clinical study
Authors: Cholepati Anup , Doiphode S.S. , Jangid Motilal
Published: October 2019

Gingival recession is defined as displacement of gingival margin apical to cementoenamel junction. Over the years gingival recession has been treated by a number of surgical techniques. Conventional mucogingival procedures such as the laterally positioned flap, free gingival graft, connective tissue graft and coronally positioned flap have been shown to be relatively successful in achieving root coverage. Gingival tissue regeneration (GTR) based root coverage has emerged as an alternative treatment because it demonstrates histologically new attachment formation. The aim of this study was to compare coronally positioned flap procedures in gingival recession defects with or without using a collagen barrier membrane.

The purpose of this study was to evaluate the wrist-worn device Mio FUSE, which estimates heart rate (HR) based on photo-plethysmography, 1) in a large study group during a standardised activity, 2) in a small group during a variety of activities and 3) to investigate factors affecting HR accuracy in a real-world setting. First, 53 male participants (20 ±1 years; 1.79 ±0.07 m; 76.1 ±10.5 kg) completed a 35-km march wearing the Equivital EQ-02 as a criterion measure. Second, 5 participants (whereof 3 female; 29 ±5 years; 1.74 ±0.07 m; 67.8 ±11.1 kg) independently performed 25 activities, categorised as sitting passive, sitting active, standing, cyclic and anti-cyclic activities with the Polar H7 as a criterion device. Equivalence testing and Bland-and-Altman analyses were undertaken to assess the accuracy to the criterion devices. Third, confounders affecting HR accuracy were investigated using multiple backwards regression analyses. The Mio FUSE was equivalent to the respective criterion measures with only small systematic biases of -3.5 bpm (-2.6%) and -1.7 bpm (-1.3%) with limits of agreements of ±10.1 bpm and ±10.8 bpm during the 35-km march and during different activities, respectively. Confounding factors negatively affecting the accuracy of the Mio FUSE were found to include larger wrist size and intensified arm and/or wrist movement. The wrist-worn Mio FUSE can be recommended to estimate overall HR accurately for different types of activities in healthy adults. However, during sporting activities involving intensified arm and/or wrist movement or for detailed continuous analysis, a chest strap is preferred to the Mio FUSE to optimise HR estimation accuracy.
Les politiques de jumelage à la ville de Bouaké : quels discours pour le développement local?
Authors: Tenan Yéo , Kouamé Kouakou , Dali Chantale
Published: September 2019

Dans cet article, nous proposons de faire une analyse de l’impact du discours des politiques de jumelage sur le développement de la ville de Bouaké, plus particulièrement sur la reconstruction post-conflit de cette cité. Le discours des programmes de jumelage était à l’origine destiné à rapprocher les peuples dans une visée émulatrice de paix et d’harmonie. Toutefois, ce discours s’est étendu depuis quelques décennies à la sphère économique dans une vision d’action du discursif sur le social en promouvant les villes sur le marché désormais ouvert et mondialisé. Ainsi, à l’image de ses consoeurs, le discours diplomatique de Bouaké prend une configuration particulière qui caractérise ses ambitions et ses attentes dans la coopération. Cependant, l’impact de ce discours sur le développement de la ville est faible et ne répond pas aux besoins prioritaires de la reconstruction post-conflit. Ce qui résulte de notre analyse est une inadéquation entre la vision véhiculée par le discours de la coopération et les actions qui découlent de celui-ci.

Previous work has demonstrated that estrogen receptors are transcriptionally active in the absence of ovarian estrogens. The current work aims to determine whether brain-derived estrogens influence estrogen receptor-dependent transcription after short- or long-term loss of ovarian function. Experiments were conducted using estrogen response element (ERE)-Luciferase reporter mice, which express the gene for luciferase driven by consensus ERE, allowing for the quantification of ERE-dependent transcription. Brain regions examined were hippocampus, cortex, and hypothalamus. In Experiment 1, short-term (10 d) ovariectomy had no impact on ERE-dependent transcription across brain regions compared with sham surgery. In Experiment 2, chronic intracerebroventricular administration of the aromatase inhibitor letrozole significantly decreased transcriptional activity in 10-d-old ovariectomized mice across brain regions, indicating that the sustained transcription in short-term ovariectomized mice is mediated at least in part via actions of neuroestrogens. Additionally, intracerebroventricular administration of estrogen receptor antagonist ICI-182,780 blocked transcription in 10-d-old ovariectomized mice across brain regions, providing evidence that sustained transcription in ovariectomized mice is estrogen receptor dependent. In Experiment 3, long-term (70 d) ovariectomy significantly decreased ERE-dependent transcription across brain regions, though some residual activity remained. In Experiment 4, chronic intracerebroventricular letrozole administration had no impact on transcription in 70 d ovariectomized mice across brain regions, indicating that the residual ERE-dependent transcription in long-term ovariectomized mice is not mediated by neuroestrogens. Overall, the results indicate that ERE-dependent transcription in the brain continues after ovariectomy and that the actions of neuroestrogens contribute to the maintenance of ERE-dependent transcription in the brain following short-term, but not long-term, loss of ovarian function.
