BACKGROUND

Multidisciplinary rounds (MDR) facilitate timely communication amongst the care team and with patients. We used Lean techniques to redesign MDR on the teaching general medicine service.

OBJECTIVE

To examine if our Lean‐based new model of MDR was associated with change in the primary outcome of length of stay (LOS) and secondary outcomes of discharges before noon, documentation of estimated discharge date (EDD), and patient satisfaction.

DESIGN, SETTING, AND PATIENTS

This is a pre‐post study. The preperiod (in which the old model of MDR was followed) comprised 4000 patients discharged between September 1, 2013, and October 22, 2014. The postperiod (in which the new model of MDR was followed) comprised 2085 patients between October 23, 2014, and April 30, 2015.

INTERVENTION

Lean‐based redesign of MDR.

MEASUREMENTS

LOS, discharges before noon, EDD, and patient satisfaction.

RESULTS

There was no change in the mean LOS. Discharges before noon increased from 6.9% to 10.7% (P < .001). Recording of EDD increased from 31.4% to 41.3% (P < .001). There was no change in patient satisfaction.

CONCLUSIONS

Lean‐based redesign of MDR was associated with an increase in discharges before noon and in recording of EDD.
Los derechos de la infancia y las políticas públicas. Reflexiones sobre la incidencia del hábitat en los asentamientos de origen informal en Bogotá
Authors: Ceballos Ramos Olga Lucía
Published: February 2018

Las políticas públicas para la infancia en Colombia han tenido un importante  avance en este siglo a partir de la promulgación del Código de Infancia y Adolescencia en el año 2006. Con el fin de promover la participación de los niños, niñas y adolescentes (en adelante, nna) en las decisiones que afectan sus vidas, el Estado ha desarrollado diversas herramientas para la definición de las políticas que deben plantearse en los ámbitos municipal y departamental. No obstante, la  participación de los nna en las decisiones referidas a su hábitat aún no logra transformar algunos factores que limitan el disfrute pleno de sus derechos, especialmente para quienes viven en asentamientos urbanos de origen informal. En este artículo se presentan las reflexiones finales de un estudio exploratorio sobre la incidencia de las condiciones del hábitat en el disfrute pleno de los derechos de los nna que habitan en asentamientos de origen informal en Bogotá. En este sentido, se hace énfasis en tres condiciones del hábitat que se postulan como factores con un alto impacto negativo: el hacinamiento en la vivienda, la segregación urbana y la estigmatización, todas en relación con las políticas públicas que deberían abordarlas.
Outcomes following limb salvage after combat hindfoot injury are inferior to delayed amputation at five years
Authors: Bennett P. M. , Stevenson T. , Sargeant I. D. , Mountain A. , Penn-Barwell J. G.
Published: February 2018

Objectives

The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function.

Methods

Follow-up was attempted in all United Kingdom military casualties sustaining hindfoot fractures. All respondents underwent short-form (SF)-12 scoring; those retaining their limb also completed the American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS F&A) outcomes questionnaire. A multivariate regression analysis identified injury features associated with poor functional recovery.

Results

In 12 years of conflict, 114 patients sustained 134 fractures. Follow-up consisted of 90 fractures (90/134, 67%), at a median of five years (interquartile range (IQR) 52 to 80 months). The median Short-Form 12 physical component score (PCS) of 62 individuals retaining their limb was 45 (IQR 36 to 53), significantly lower than the median of 51 (IQR 46 to 54) in patients who underwent delayed amputation after attempted reconstruction (p = 0.0351). Regression analysis identified three variables associated with a poor F&A score: negative Bohler’s angle on initial radiograph; coexisting talus and calcaneus fracture; and tibial plafond fracture in addition to a hindfoot fracture. The presence of two out of three variables was associated with a significantly lower PCS compared with amputees (medians 29, IQR 27 to 43 vs 51, IQR 46 to 54; p < 0.0001).

Conclusions

At five years, patients with reconstructed hindfoot fractures have inferior outcomes to those who have delayed amputation. It is possible to identify injuries which will go on to have particularly poor outcomes. Cite this article: P. M. Bennett, T. Stevenson, I. D. Sargeant, A. Mountain, J. G. Penn-Barwell.

Video games and dystopia: Total cities, post-cities and the political unconscious
Authors: Johnson Craig , Tulloch Rowan
Published: February 2018

Dystopian settings dominate the video game landscape. Social collapse and totalitarian repression are amongst the favourite scenarios depicted in this medium. In this article, we offer a reading of these dystopian visions, not just as an aesthetic choice or gameplay trend, but as reflective of a ‘political unconscious’ latent in these games. These games are products of a very particular set of political, cultural and historic contexts, and embody key contemporary fears and apprehensions. To trace this we focus on how the space of the city has come to be a key signifier and site of dystopian anxiety in these games. Specifically, we look at how the city functions in two video games, Fallout 3 and Mirror’s Edge, to analyse the means and mechanisms through which game spaces manifest political logics. In doing so we ultimately seek to show how video games offer us insight into contemporary political change and order.

O conceito de diálogo e o de monólogo entre russos no início do século XX: aproximações e distanciamentos
Authors: Arena Dagoberto Buim
Published: February 2018

Este ensaio tem como objetivo principal a análise dos conceitos de diálogo e de monólogo em Vigotski, Volochinov, Jakubinskij e Scherba, para confrontar os seus estudos, considerando-se a relação entre os dois primeiros com Jakubinskij, e por meio dele a relação com Scherba, este último referência de todos. Para promover esse confronto foram consultadas obras em francês que abordam o pensamento de Volochinov, Jakubinskij e Scherba, e em espanhol o de Vigotski. A conclusão é a de que Vigotski manteve os princípios defendidos pelos mestres, mas Volochinov, em suas reflexões, ampliou o conceito de diálogo, elegeu o enunciado como objeto de suas pesquisas sobre linguagem, e relegou o monólogo ao mundo da abstração.

In September 2017 a "Big Data Training School for Life Sciences" took place in Uppsala, Sweden, jointly organised by EMBnet and the COST Action CHARME (Harmonising standardisation strategies to increase efficiency and competitiveness of European life-science research - CA15100). The week programme was divided into hands-on sessions and lectures. In both cases, insights into dealing with big amounts of data were given. This paper describes our personal experience as students’ by providing also some suggestions that we hope can help the organisers as well as other trainers to further increase the efficiency of such intensive courses for students with diverse backgrounds.
Effect of slaughter weight and sex on slaughter traits and meat quality of Polish autochthonous ZLotnicka Spotted pigs crossbred with Duroc

Published: February 2018

The aim of this study was to investigate the impact of slaughter weight and sex on slaughter traits and meat quality of Zlotnicka Spotted x Duroc (ZS×D) hybrid fatteners. The material comprised 56 Zlotnicka Spotted × Duroc fatteners (28 barrows and 28 gilts) which were fattened to 245th day of life. Pigs were divided into the following three groups: Group I (n=16) <110 kg; Group II (n=23) ≥110 ≤120 kg, and Group III (n=17) >120 kg. The obtained results revealed influence of the final body weight on slaughter trait values with the exception of meatiness. Fatteners from the group with the highest weight were characterised by the thickest backfat as well as by the greatest height of the loin eye. Slaughter weight exerted a significant impact on protein content, water absorbability as well as on the pH of the longissimus thoracis et lumborum (LTL) muscle. As to the influence of sex on slaughter traits, it was found that gilts were characterised by smaller backfat thickness and higher carcass meatiness than barrows. On the other hand, no effect of the slaughter weight and sex on colour parameters and sensory quality of the LTL muscle was ascertained. All the examined parameters were at high level in all slaughter weight and sex groups. The obtained results suggest that the slaughter of ZS×D crossbreds in groups I and II exerts a beneficial influence on slaughter trait levels and, at the same time, allows maintenance of high meat quality.

Authors: Wilk Karolina
Published: February 2018

The article describes 5 countries from the world: South Korea, Japan, Singapore, Hong Kong, Finland that have the best and unusual educational systems. Thanks to the new approach to the teaching, students become very well-educated when graduate. The text emphasises the importance of foreign language knowledge. It is very interesting how much different is the approach to students in Asian countries and in Finland but both systems eventually provide very good education level to their students. The another part of the article bases for characteristic of two other EU countries – Romania and Poland. In these countries, the internal educational systems are quite similar to each other and guarantee their students very good education level. Thanks to the attendance in Erasmus exchange programme, Romanian and Polish students can broaden their mind abroad.

Published: February 2018

Purpose. Players’ tactical skills are crucial for a successful, high-standard career in soccer. Although recent studies propose and apply the analysis of young players’ tactical skills through the understanding of their knowledge about tactical principles, no research has compared the development of these specific tactical skills throughout a soccer specific season in different youth academies. This article aimed to compare the development of tactical skills in U-14 and U-15 soccer players throughout a season. Methods. The tactical skills of 30 athletes (16 U-15 and 14 U-14) of a sports club were evaluated during 10 months with the System of Tactical Assessment in Soccer (FUT-SAT). The incidence of tactical principles and the percentage of successful principles in offense and defence were compared with the use of a two-way ANOVA (category × time). Results. Reduction was observed in the incidence of actions of offensive unity in the U-15 athletes throughout the season and a higher incidence of offensive coverage compared with U-14. Moreover, U-15 athletes increased their percentage of successful actions, both offensive and defensive, and presented a higher performance than U-14 players. Conclusions. Tactical performance of U-15 soccer athletes increases over a sports season, which is not observed in the U-14 category, although players from both groups presented changes in the incidence of offensive and defensive tactical principles. This supports the non-linearity of tactical skills acquisition and development in soccer, as well as justifies the need of constant assessment during the training process across the ages.
Elemente einer globalisierten Ideengeschichte der Vormoderne
Authors: Mulsow Martin
Published: February 2018

„Globale Ideengeschichte“ ist ein neues Feld, das noch auf der Suche nach fruchtbaren methodischen Ansätzen ist. Dieser Aufsatz geht von der Frage aus, wie die kulturgeschichtliche Grundierung der Ideengeschichte auch bei einer Ausweitung der Ideengeschichte auf globale Kontexte erhalten werden kann. Der Vorschlag: Eine Aufmerksamkeit für das Referenzverhalten in der Globalisierung, nämlich die Bezugnahme auf räumlich und zeitlich weit Entferntes. Gerade für die Vormoderne mit ihren Expansionen ins Ungewisse sind da interessante Phänomene zu konstatieren: Fehlreichweiten der Referenz, wenn das entdeckte Land in Wirklichkeit ein anderes ist als intendiert, wenn der verehrte Autor in Wirklichkeit aus einer viel jüngeren Zeit stammt als geglaubt; Triangulation, wenn das Neue mit Hilfe von Bezügen auf Antikes wahrgenommen wird; die Globalisierung ganzer philosophischer Sprachen, die präjudizieren, wie unbekannte Denkmuster adaptiert werden; schließlich die Verflechtung von intellektuellen Welten durch wechselseitige Missverständnisse und falsche Bezugnahmen. Im Durchgang durch eine Fülle an Forschungsliteratur werden so die Konturen einer integralen und unverkürzten „Global Intellectual History“ sichtbar, die nicht mehr nur Transmissionen beschreibt, die auf das moderne Europa zulaufen, sondern auch transversale Ideenmigrationen ohne europäische Beteiligung, mit Narrativen, die fern von unseren gewohnten Meistererzählungen sind.
Smart Demand Response Management of Islanded Microgrid using Voltage-Current Droop Mechanism
Authors: Jha Sumit Kumar , Kumar Deepak , Kamwa I.
Published: February 2018

The reduction of power of the autonomous microgrid is proposed in this paper. The concept utilized is Conservative Voltage Reduction (CVR). The active and reactive power consumption of the microgrid decreases and a power reserve of the system increased. The voltage–current droop mechanism is used to lessen the voltage of the DG and it reduces the consumption of power on the consumer side. This reduced power is used to cater more demands. The control strategy is used to cater the greater number of loads at the time of power shortage. The DG taken in this paper is photovoltaic (PV) system and perturb & observe MPPT is used. The interleaved boost converter is used as DC- DC converter as it lessens the ripple of the output voltage and inputs current. The simulation is done on MATLAB platform and results are validated at different loading conditions and comparison has been done with P-f/Q-V mechanism.

Published: February 2018

Background: Acute basophilic leukemia is a rare subtype of acute myeloid leukemia, as categorized by the 2008 World Health Organization classification of myeloid neoplasms. Acute basophilic leukemia diagnosis requires thorough morphological, cytochemical, immunophenotypic, molecular, and cytogenetic studies and exclusion of other hematological neoplasms associating basophilia. The disease course is defined by histamine driven, occasionally life-threatening respiratory, cardiovascular, cutaneous or digestive complications, as well as primary refractoriness to standard therapy. Clinical presentation: We herein report a case of a 63-year-old asthmatic female patient diagnosed with acute basophilic leukemia, associated with previously unpublished cytogenetic features and FLT-3 ITD mutation, pulmonary leukostasis and spontaneous pulmonary capillary leak syndrome, which worsened immediately following chemotherapy initiation. Respiratory complications were successfully managed, but recrudesced upon emergence of refractory disease and were ultimately fatal. We highlight the likelihood of pulmonary complications induced by basophil degranulation and tumor lysis in hypercellular acute basophilic leukemia and the potential benefit of histamine receptor blockade in this setting.

Published: February 2018

Background. Celiac disease (CD) is significantly underdiagnosed, despite significant efforts made in the last decades to increase its diagnostic rate. This has lead to a high need for developing new diagnostic strategies. Our aim was to evaluate the diagnostic performance of two routine hematologic indices for CD. Methods. In a prospective observational study, 34 newly diagnosed CD patients, 34 age-sex matched controls with irritable bowel syndrome (IBS) and 16 treated CD patients were assessed regarding the differences in mean lymphocyte count (LY), red blood cell distribution width (RDW) and their ratio (RDW/LY). Results. Elevated RDW (>14) and lymphopenia (<1.5 x 10e9/L) were more frequently seen in newly diagnosed CD patients compared to IBS control group and treated CD patients. Newly diagnosed CD patients had significantly higher mean values of RDW/LY - 10.09, compared to 7.72 in the CD-treated group and 6.79 in IBS controls (p<0.01). Subgroup analysis revealed that RDW/LY was higher in patients with destructive histology (Marsh≥3a), 10.54 vs. 7.99. For a value over 7, RDW/LY had a sensitivity of 88.24% (95% CI 72.55-96.70%) and AUROC of 0.785 (95% CI 0.683- 0.887). Conclusions. RDW/LY ratio is a widely available tool which could be used routinely in clinical practice for CD screening.
Types and forms of physical exercise in the private schools and gymnastic societies for physical exercising in the Principality and the Kingdom of Serbia
Authors: Mijatović Slađana
Published: February 2018

The previous studies on the gymnastic societies of the Principality and the Kingdom of Serbia did not seriously deal with the types of physical exercise practiced therein. It may be assumed that is due to a lack of the information preserved thereabout. For these reasons, in this study we searched for the findings about the types of physical exercise applied in the private training schools where some skills (fencing, swimming, archery, horse riding) were learnt and practiced, then in the societies for physical exercising (gymnastics) as well as in the chivalrous societies. The aim of this study was to determine the types and forms of physical exercise practiced in the private training schools, societies for physical exercising (gymnastics) and chivalrous societies of the Principality and the Kingdom of Serbia. The historical method was applied in this paper. In this paper, we presented the results, i.e. the types of physical exercise practiced in the private training schools (Schools of Fencing, Steva Todorović's School of Painting, Askanius Sedlmayer's School of Gymnastics), societies for physical exercising (gymnastics) and chivalrous societies (Belgrade Society for Gymnastics and Fighting, Belgrade Gymnastic Society "Sokol", Civil Gymnastic Society "Dušan Silni", Sokol societies). Based on the comparative analysis of the types of the apparatuses used and the exercise methods applied it has been determined that private schools mainly implemented the Turner system using most of Jahn's Turner apparatuses. However, in the societies for physical exercising, in addition to the Turner exercise method, the Swedish system of physical exercise was partially applied as well. Upon the appearance and acceptance of the Sokol idea, the application of the Sokol training method also started in the established Sokol societies, and soon afterwards in the army, and primary and secondary schools as well.
Purification, immobilization and characterization of thermostable α-amylase from a thermophilic bacterium Geobacillus sp. TF14
Authors: Keskin Şaban , Ertunga Nagihan Saglam
Published: February 2018

Objective

In this study, α-amylase from a thermophilic bacterium Geobacillus sp. TF14 was purified and immobilized on two different supports.

Methods

Ion exchange and hydrophobic interaction chromatography techniques were employed for the purification.

Results

The enzyme was purified as 17.11 fold and determined as a single band of 54 kDa on SDS-PAGE. Purified enzyme showed two pH optimums of pH 5.00 and pH 9.00 and the enzyme is quite stable at these pHs over a period of 48 h. Purified enzyme showed maximal activity at 75°C and stability at this temperature over a period of 72 h. It was observed that Ca2+ activated the enzyme at about 70% at 5 mM final concentration. SDS, Triton X100, Triton X114 and Tween 20 caused around 50% loss of initial activity at a final concentration of 1% (w/v). Purified enzyme was immobilized on the surface of Dowex and chitin. Immobilization highly enhanced temperature optima and thermal stability. Dowex immobilized enzyme maintained most of its initial activity in the presence of SDS, Triton X100, Triton X114 and Tween 20 at a concentration of 1%.

Conclusion

It can be concluded that the purified enzyme may find application in many fields of starch based industries.
Manner and result modifiers. The V ben V construction in Catalan
Authors: Espinal M. Teresa , Mateu Jaume
Published: February 2018

This paper analyzes the ingredients of a Romance construction, henceforth named the V ben V construction, consisting of a verb and its theme object in combination with a degree adverb ben ‘{well, really}’ followed by a verb in past participle or an adjectival form. It describes the properties and restrictions of the various constituents involved in this construction, and it presents a new analysis focusing on the properties of the main predicate, the theme object, the degree adverb ben and the degree phrase ben+VPP/A. It accounts for the potential manner and result readings of the adjunct constituent that ben introduces (i) by postulating that the ben+VPP/A modifier always predicates of the (sub)event expressed by the verb (an activity or a change of state), (ii) by associating manner with a do verbal layer, and result with a become verbal layer, and (iii) by identifying different aspectual structures in the complement position of the degree adverb.
On the Closure of the Image of the Generalized Divisor Function
Authors: Sanna Carlo
Published: February 2018

For any real number s, let σsbe the generalized divisor function, i.e., the arithmetic function defined by σs(n) := ∑d|nds, for all positive integers n. We prove that for any r > 1 the topological closure of σ−r(N+) is the union of a finite number of pairwise disjoint closed intervals I1, . . . , Iℓ. Moreover, for k = 1, . . . , ℓ, we show that the set of positive integers n such that σ−r(n) ∈ Ikhas a positive rational asymptotic density dk. In fact, we provide a method to give exact closed form expressions for I1, . . . , Iℓand d1, . . . , dℓ, assuming to know r with sufficient precision. As an example, we show that for r = 2 it results ℓ = 3, I1= [1, π2/9], I2= [10/9, π2/8], I3= [5/4, π2/6], d1= 1/3, d2 = 1/6, and d3= 1/2.

Published: February 2018

The investigation of the supramolecular interactions between the lithium isothiocyanate salt and 18-crown-6 (18C-6) in commercial tetrahydrofuran leads to the formation of a lithium compound, LiNCS(H2O)(18C-6) (1). In the crystal structure the asymmetric unit contains two similar LiNCS(H2O)(18C-6) molecules. Solid-state photoluminescence experiments have shown that compound 1 emits violet luminescence, and its possible emission mechanism was investigated in detail based on theoretical calculations.
Aminkomplexe des Goldes, Teil 10: Gold(I)-thiocyanat-Komplexe mit Tetrahydrothiophen, Dimethylsulfid, Ammoniak, Aminen und Azaaromatena

Published: February 2018

The reaction of (tht)AuCl (tht=tetrahydrothiophene) with KSCN leads to a mixture of gold(I) thiocyanate AuSCN and [(tht)2Au]+ [Au(SCN)2]−
1. The compounds were separated and the X-ray structure of 1 confirmed as an alternating chain of anions and cations linked by aurophilic contacts. Either pure AuSCN or the mixture was used to synthesize further derivatives of AuSCN, all of which were investigated by X-ray methods. Most products were of limited stability when removed from their mother liquor. The dimethyl sulfide derivative 2 is molecular, (Me2S)AuSCN; the ammonia derivative 3 is ionic, [(NH3)2Au]+ [Au(SCN)2]−. The reaction with 2,2-bipyridyl leads (presumably by involvement of the solvent or of atmospheric moisture) to [bipy-H]+ [Au(SCN)2]−
13. All other products involve amines or azaaromatics as ligands L. The primary amine tert-butylamine forms an ionic product [L2Au]+ (SCN)−
4. The secondary amines piperidine and dibenzylamine lead to molecular structures LAuSCN (5 and 6), whereas pyridine-based azaaromatics lead to ionic products [L2Au]+ [Au(SCN)2]− with L=2-, 3- or 4-picoline (7–9), 2,4-, 3,4- or 3,5-lutidine (10–12). The 3,4-lutidine derivative 11 forms two polymorphs that tend to form mixed crystals. The dominant features of the crystal packing for 7–12 are short aurophilic interactions.

J Strength Cond Res 32(9): 2686–2700, 2018—Numerous foundational movements performed during basketball are predicated on underlying power-related attributes, including speed, change-of-direction (COD), and jumping. Accordingly, fitness testing batteries for basketball have incorporated an assortment of linear speed tests, COD tests, and jump tests. However, because of the wide variety of testing options, it is difficult for basketball practitioners to select appropriate testing protocols for the assessment of power-related attributes. As a result, there is a need to review the relevant literature to identify game-specific, power-related attributes important in basketball and the most appropriate tests available to assess power-related attributes for basketball practitioners. Therefore, the aims of this review were to: (a) identify essential power-related attributes important in basketball; (b) discuss the suitability of common and novel power-related tests; and (c) provide recommendations for future research and best practice approaches for basketball coaching staff. In this review, we propose a series of novel tests that are more targeted and specific to basketball movements including: (a) 5- and 10-m linear sprints, (b) modified agility T-test, (c) change-of-direction deficit (CODD), (d) lateral bound, (e) Sargent jump, (f) one-step jump, and (g) isometric midthigh pull test. Improved testing of power-related attributes should enable basketball practitioners to develop targeted training plans for enhancing player performance.

McMahon, JJ, Suchomel, TJ, Lake, JP, and Comfort, P. Relationship between reactive strength index variants in rugby league players. J Strength Cond Res 35(1): 280–285, 2021—Two reactive strength index (RSI) variants exist, the RSI and RSI modified (RSImod), which are typically calculated during the drop jump (DJ) and countermovement jump (CMJ), respectively. Both RSI variants have been used to monitor athletes' ability to complete stretch-shortening cycle actions quickly, but they have never been compared. The purpose of this study was to determine whether they yield relatable information about reactive strength characteristics. Male professional rugby league players (n = 21, age = 20.8 ± 2.3 years, height = 1.82 ± 0.06 m and body mass = 94.3 ± 8.4 kg) performed 3 DJs (30 cm) and CMJs on a force plate. Reactive strength index and RSImod were subsequently calculated by dividing jump height (JH) by ground contact time (GCT) and time to take-off (TTT), respectively. All variables were highly reliable (intraclass correlation coefficient ≥0.78) with acceptable levels of variability (coefficient of variation ≤8.2%), albeit larger variability was noted for DJ variables. Moreover, there was a large relationship between RSI and RSImod (r = 0.524, p = 0.007), whereas very large relationships were noted between JHs (r = 0.762, p < 0.001) and between GCT and TTT (ρ = 0.705, p < 0.001). In addition, RSI (0.90 ± 0.22) was largely and significantly (d = 2.57, p < 0.001) greater than RSImod (0.47 ± 0.08). The DJ-derived RSI yields much larger values than the CMJ-derived RSImod and although a large relationship was noted between them, it equated to just 22% shared variance. These results suggest that the 2 RSI variants do not explain each other well, indicating that they do not assess entirely the same reactive strength qualities and should not be used interchangeably.

THIS ARTICLE PROVIDES A FRAMEWORK FOR SELECTING THE MOST APPROPRIATE ASYMMETRY EQUATION BASED ON THE SELECTED TEST METHOD, ENSURING ACCURATE CALCULATION AND INTERPRETATION. IN ADDITION, CONSIDERATIONS FOR DATA ANALYSIS HAVE ALSO BEEN INCLUDED AS A GUIDE FOR PRACTITIONERS ON THE RELEVANCE OF MONITORING INTERLIMB DIFFERENCES LONGITUDINALLY.
Extending Low-Temperature Differential Scanning Calorimetry from Paste to Mortar and Concrete to Quantify the Potential for Calcium Oxychloride Formation
Authors: Suraneni Prannoy , Weiss Jason
Published: February 2018

Calcium chloride–based deicing salts can react with calcium hydroxide in concrete pavements, resulting in the formation of calcium oxychloride. The formation of calcium oxychloride can cause damage in the pavements, especially at the joints. Recently, it has been shown that low-temperature differential scanning calorimetry can be used to measure calcium oxychloride contents in cement pastes exposed to calcium chloride. This article explores the extension of the low-temperature differential scanning calorimetry test method from applications on ground paste to ground mortar and concrete. Specifically, the influence of dilution due to the aggregate volume causes the measured amount of calcium oxychloride to be smaller in mortar and concrete than the pastes. To successfully measure the amount of calcium oxychloride, a higher powder-liquid ratio is used in concretes as compared to pastes. Low-temperature differential scanning calorimetry can successfully be used to measure the amount of calcium oxychloride in ground mortars and concrete; however, there is an increase in the variation of the measurement, and, as such, it is recommended that the average of three tests should be considered as a test specimen.

Published: February 2018

C1q/tumor necrosis factor-related protein 3 (C1QTNF3) is a novel adipokine with modulating effects on metabolism, inflammation and the cardiovascular system. C1QTNF3 expression levels in the sera and omental adipose tissues of women with PCOS are low compared to control subjects. However, the expression and function of C1QTNF3 in the ovary has not previously been examined. Here, we assessed the expression patterns of C1qtnf3 in the ovary and explored its role in folliculogenesis. The C1qtnf3 transcript abundance was higher in large follicles than in small follicles and was under the influence of gonadotropin. C1QTNF3 was detected mainly in the granulosa cells and oocytes of growing follicles and modestly in the granulosa cells of atretic follicles and in luteal cells. Excess androgen significantly decreased C1QTNF3 expression in the ovaries in vivo and in granulosa cells in vitro. Recombinant C1QTNF3 protein accelerated the weight gain of ovarian explants and the growth of preantral follicles induced by follicle stimulating hormone (FSH) in vitro. The stimulatory effect of C1QTNF3 on ovarian growth was accompanied by the initiation of AKT, mTOR, p70S6K and 4EBP1 phosphorylation, an increase in CCND2 expression and a reduction in cleaved CASP3 levels. Moreover, the addition of C1QTNF3 accelerated proliferation and reduced activated CASP3/7 activity in granulosa cells. In vivo, the ovarian intrabursal administration of the C1QTNF3 antibody delayed gonadotropin-induced antral follicle development. Taken together, our data demonstrate that C1QTNF3 is an intraovarian factor that promotes follicle growth by accelerating proliferation, decelerating apoptosis and promoting AKT/mTOR phosphorylation.

The quasi b-metric dislocated space (dqb-metric space) was first introduced by Klin-eam and Suanoom in 2015. They had been proven the uniqueness of the fixed point in the dqb-metric space on cyclic mapping that provides the cyclic Banach contraction conditions. Furthermore, in 2016 Dolicanin et al showed that the fixed point singularity properties in the dqb-metric space can be proven without requiring the mapping to satisfy the cyclic metrics Banach contraction conditions. Both statements are proved equivalent in this paper.

Platyphora Gistel, 1857 from Itatiaia National Park, southeastern Brazil: new synonymy and new records (Insecta, Coleoptera, Chrysomelidae)
Authors: Sampaio Aline , Monné Marcela
Published: February 2018

Abstract Platyphora Gistel, 1857 is the largest genus in Chrysomelinae with about 450 species of which 181 occur in Brazil. The Itatiaia National Park is one of the most important Conservation Units of the Atlantic Rainforest and 36 Platyphora species are recorded from the park. We have recorded 38 species of Platyphora. The synonymy of Platyphora fraterna (Stål, 1857) and Platyphora fasciatomaculata (Stål, 1857) is proposed. Platyphora bilimbata (Stål, 1857), P. carolina (Stål, 1858) and P. semiviridis (Jacoby, 1903) are new records for the park; additional distributional records are provided for 18 species. Of the 38 species, 24 are illustrated for the first time.
