Time, memory and actors: Representation of ageing in recent Swedish feature film
Authors: Koskinen Maaret
Published: February 2019

As has been noted in scholarship across various disciplines, issues of age and ageing have attracted much interest in recent years. In film production as well, ageing character actors have entered centre stage, in both popular films (for instance the Hotel Marigold films) and existential dramas (for instance Lucky, with 90-year-old Harry Dean Stanton in his last role). However, little has been written on Swedish film production in this regard. This article attempts to demonstrate, through an empirical overview, that interest in age and ageing has increased in feature film during the last two decades, not only internationally but more specifically in Swedish film. This article also strives to hypothesize, drawing on the area of memory studies, that the mere representation of ageing bodies and identities by well-known actors may inspire positive affective experiences related to memory, and that such representations, accumulatively across time, may be beneficial to health.

Authors: Khalaf Husam S. , Al-Dulaimy Zainab A.H. , Abbas Ahmed M. , Saleem Maida H.
Published: February 2019

At the temperature 298.15 K, some physical properties such as: refractive indices (nD), viscosities (η) and densities (ρ) were studied in four liquid-liquid mixtures: carboxylic acids (HCOOH, CH3COOH, CH3CH2COOH and CH3CH2CH2COOH) with tetrahydrofurfuryl alcohol (THFA) with the identified configuration set. These empirical data were utilized to estimate the excess molar volumes (Vm E), refractive index perversions (ΔR), viscosity deviations (ηE) and excess molar Gibbs free energy (ΔG*E). Values of Vm E, ηE , ΔG*E and ΔR were plotted versus mole fraction of tetrahydrofurfuryl alcohol. In all cases, the values of Vm E, ηE , ΔG*E and ΔR that obtained in this study were found to be negative at 298.15 K. The excess parameters were applied in the Redlich-Kister equation by utilizing multi-parameter coefficients that concluded binary coefficients and in respect to the standard deviation. The difference of these characteristics with the formation of binary liquid systems indicates the absence of bipolar bond, variation in the shape and size of component molecules, hydrogen bonding and dipolar interaction among unlike molecules.

The stability of aceclofenac under stress conditions was assessed to identify the degradation products. So, it was subjected to stress conditions like acid, base and oxidation, according to ICH guideline Q1A (R2). One degradation product formed when the drug was subjected to acid stress. Three degradation products were formed during the basic stress condition. The drug substance was found to be stable to oxidative stress. The degradants formed during the stress were separated on a C-18 column using gradient preparative HPLC elution. The only product (DP-2) formed during the acid stress and this one is same as of one of the three degradation products (DP-1, DP-2, DP-3) were formed during base stress. 1D and 2D NMR spectra and mass spectral analysis supported the proposed structures for the products. The products DP-2 and DP-3 have been reported earlier but this is the first report of product DP-1 as a degradation product of aceclofenac.

Published: February 2019

Y2SiO5:Ce3+ (1-7 mol %) nanophosphors were prepared by solution combustion method using oxalyldihydrazide fuel. The phosphors were characterized by X-ray diffraction, scanning electron microscopy, UV-visible and Fourier transform infrared spectroscopy. The XRD patterns confirm the monoclinic structure of the prepared phosphors, with crystallite size of 66-74 nm. The surface morphology and elemental composition were evaluated by SEM and energy dispersive X-ray analysis. The optical band gap was calculated and is between 4.66 eV – 4.9 eV. The presence of Si-O-Si and Y-O bonds was confirmed by the FTIR spectra. Effect of cerium concentration on photoluminescence and thermoluminescence intensity were interpreted. The photoluminescence emission spectrum was recorded under excitation wavelength of 370 nm, the emission spectra showed three significant peaks positioned at 418 nm, 459 nm and 485 nm, which are ascribed to electronic transitions between 5d-4f levels. The nature and activity of trap centers were evaluated from the parameters obtained from Chen′s peak shape method. The intense blue emission by phosphor makes it a competent material for blue emission display devices. Also, its thermoluminescence properties make it a good material for dosimetric applications.

Authors: Latoh Leandro Porto , Gomes Erik Nunes , Zuffellato-Ribas Katia Christina
Published: February 2019

The use of Brazilian native species for ornamental purposes is a promising alternative for local floriculture. Seeking to contribute with new information in this context, the present study aimed to evaluate the rooting performance of mini-cuttings from three Tibouchina species (T. aff. fothergillae, T. heteromalla and T. moricandiana var. vinacea) as affected by the use of indolebutyric acid (IBA) and fulvic acid (FA). Mini-cuttings with 5 cm in length were prepared with plant material from clonal mini-hedges and submitted to different treatments as follows: control treatment (T1); 2,000 mg L-1 IBA (T2); 2,000 mg L-1 FA (T3) and 2,000 mg L-1 IBA + 2,000 mg L-1 FA (T4). Planting was carried out in plastic containers filled with vermiculite, and, after 26 days under greenhouse conditions, the following variables were evaluated: mini-cuttings rooting percentage (RP), roots number (RN), roots length (RL), initial leaves maintenance (ILM) and sprouting (SP). The experiment was conducted under a completely randomized design in a 3 x 4 factorial scheme, with four replications and 20 minicuttings per plot. Rooting percentages were higher than 90% in all three species, regardless of IBA or FA treatments. RP, ILM and SP did not show statistically significant interaction between the treatments. For RN, T2 and T4 promoted the best results on T. aff. fothergillae (12.62 and 14.92, respectively) and T2 resulted in maximum values for T. heteromalla (15.65). For RL, T2 and T4 were statistically superior on T. heteromalla (9.52 and 8.20 cm, respectively). The use of IBA and FA is dispensable for rhizogenesis induction on mini-cuttings from the studied species

Authors: Espinosa Ríos Edgar Andrés , González López Karen Dayana , Hernández Ramírez Lizeth Tatiana
Published: February 2019

El propósito de esta investigación fue indagar cómo los procesos reflexivos y los fundamentos de la mediación didáctica contribuyen a los procesos de enseñanza que realizan los docentes en formación en Ciencias Naturales durante su práctica educativa. Se trata de un estudio de caso en el que se diferencia cuatro momentos: la selección de la muestra de estudio, la formación teórico-práctica realizada por un docente mediador, la práctica educativa realizada por los docentes en formación con una intensidad de 25 horas y el análisis de las filmaciones de las clases y las entrevistas realizadas por los docentes en formación. Como resultado se observó la importancia de los procesos de reflexión y los fundamentos de la mediación didáctica en la formación docente y la necesidad de articular los conocimientos disciplinares, pedagógicos y didácticos desde contextos reales. El hecho de tener bases sólidas desde lo disciplinar no garantiza el buen desempeño, de ahí que los contextos reales se liguen a la reflexión sobre la acción en función de volver consciente las debilidades y fortalezas, desarrollando la capacidad de reflexión para mejorar los procesos de enseñanza, aprendizaje y evaluación.

Este artículo se enfoca en la evaluación del aprendizaje y su influencia en las prácticas evaluativas a partir del reconocimiento de las concepciones que tienen los estudiantes y docentes implicados en el acto educativo. Esto, fundamentado en investigaciones y opiniones de diferentes autores acerca del tema tratado. Se detalla en los hallazgos investigativos que ponen de relieve las reflexiones construidas por un equipo de docentes y maestros en formación del departamento de Ciencias Naturales y Educación Ambiental de la Universidad de Córdoba (Colombia), en el marco del proyecto de investigación “Caracterización de las prácticas evaluativas en las instituciones educativas del departamento de Córdoba”. Se realizó un proceso de búsqueda e identificación de información documental en bases de datos, categorizadas y analizadas a través de instrumentos de rúbrica y glosa partiendo de un método heurístico (que conllevó a la preparación, selección y búsqueda). Lo anterior permitió obtener criterios de caracterización de cada investigación. En una posterior fase hermenéutica, se realizaron reflexiones documentadas y contrastadas para constituir las conclusiones. Finalmente, se establece que las concepciones de los docentes y estudiantes tienen relevancia recíproca. Los docentes son los encargados de asesorar el proceso evaluativo y determinan si se ha alcanzado un aprendizaje significativo; de otra parte, los estudiantes, desde la concepción de conocer, actúan como agentes pasivos o activos en el proceso evaluativo. Además, la evaluación es tomada como un medio que permite determinar las debilidades y fortalezas que posee tanto el docente como el estudiante.

Authors: Fischer Szabolcs , Juhász Erika
Published: February 2019

This paper demonstrates the results in the research topic of the railway ballast particles’ breakage test with unique laboratory test. The most railway lines in the world have so called traditional superstructure (ballasted tracks). In the past few years there were a lot of railway rehabilitation projects in Hungary, as well as abroad. Nowadays cannot be expected that there is enough quantity of railway ballast in adequate quality, because of the modifications and restrictions in the related regulations in Hungary since 2010. In Hungary there are only a few quarries which are able to ensure adequate railway ballast material for construction and maintenance projects for speed values between 120 and 160 km/h. This may cause supply and quality risk in production of railway ballast. The authors’ research’s main goal is to be able to simulate the stress-strain effect of ballast particles in real and objective way in laboratory conditions as well as in discrete element modelling.

This research aims to measure the accuracy and response times (RTs) from Javanese women to recognize the facial expression. Javanese sampel (N=30) was used in this study. Data were analyzed using two-way Anova with R Programming software and experiment was done using Python Programming. The research yielded: 1) Among all, happy and joy have less RTs. However, there is no significant effect between joy and happy; 2) Among the blocks, block two is considered the fastest, which is followed by block three. Priming upward spiral, however more prone than priming downward spiral in the normal sampel; 3) Sad considered being the emotion which is the most accurate-despite having the longest RTs. According to subject, sad expression was influenced by repetitive exposure from social media content. Positive expression is likewise the expression that being hoped in any interaction, deserved to watch and then being responded. Besides, negative emotion has many labels in Javanese custom that prevent them to be regular expression.

Trends in Early Childhood Education Practice and Professional Learning with Digital Technologies
Authors: Murcia Karen , Campbell Coral , Aranda George
Published: February 2019

This literature-based article explores key trends in the integration of digital technologies in education and aims to highlight issues and challenges in the relationship between technology, pedagogy and early years’ education practices. The article explores how technology, teacher training initiatives and productive play-based pedagogy could be used to improve digital literacy outcomes for early childhood learners. While situated within the Australian context, more global literature is also reviewed to provide an international perspective. This review of trends in the integration of digital technologies in education is timely due to the national and international focus on STEM (Science, Technology, Engineering and Mathematics) education, arguably for economic sustainability and the quality standards expected in early childhood education. The role of digital technologies in early childhood is increasingly discussed and negotiated in learning centres. Educators are wanting support in understanding how young children can be creators of technology rather than simply being consumers of digital products.

A Contemporary Move towards Study of Light and Colours An Analysis of Munawar Mohiud Din’s Landscape Paintings
Authors: Sheikh Samina Zia
Published: February 2019

Painting is related to the psychology of the period in which it is produced. It reveals and expresses the relationship of a society to the world. Impressionism belonged to the time when mission of the painting was to reassure the beholder and
banish the tension of reality. Impressionism in post modern era is less directly significant. Fewer artists assure to the philosophy of intellect or self expression commonly known as Impressionistic concern, for nature. Munawar Mohiud Din’s eminence
as impressionist attracts a number of artists working with oil paints. His masterly skill reveals delight in painting while squinting through an imaginary view finder allowing composition to take a clear form. In his paintings serenity and
truthfulness of ‘impressions’ such as trees, flowers, vegetations, long paths, make all of his works notably phenomenon. Painterly strokes in his paintings look abstract but the application of right colour and value relationship bring surprising
reality to the composition. All paintings possess layers of colours that are effective, delicate and thin when multi layers are added. Many of his works offer perceptibly higher key with bright colours and lightness of touch which distinguishes him
as an astonishing impressionist without question. His peculiar move towards colour theory, momentary capture and inspirational strokes proves and identify him as an outstanding impressionist without question.

The first isolation of HA was in the year 1934, but research on HA and its clinical significance in health and disease started only in the year 1970. Both HA and HASs play a significant role in many physiological and pathological processes.
The cellular HA synthesis are coordinated collectively by HASs. HA has wide range of applications in clinical practice. HAS1 is expressed in malignancies like bladder and prostate cancers as well as in myeloma and malignantmesothelioma. Studies have
predicted the involvement of HA in endothelial cell proliferation migration, new vessels formation and leucocytes recruitment. HA was found to influence stroma cell recruitment, tumor angiogenesis and epithelial –mesenchymal transition. Measurement
of HASs may help to find out tumor aggressiveness towards targeting appropriate therapies. Measurement of both HA and CD44 will be very useful in the evaluation of breast cancer. Many different assays based on ELISA and PCR are now available for
reliable quantification of HA. It also play a key role in bone metabolism and its latest application is for breast cancer screening and prognostic evaluation. It has also therapeutic value in multidrug resistance. Assays for HA and HASs have also
been discussed in this review article. The contents of this review article will be very useful for future researchers to evaluate a simple, reliable and cost saving methods for measuring HA and HASs in human blood and to include them as metabolites
for cancer screening.
A DRAFT CLASSIFICATION OF ATTRIBUTES IN KOREAN AND POLISH LANGUAGES
Authors: BOROWIAK Anna
Published: February 2019

Analyzing various classifications of sentence parts in Korean and Polish, it is easy to identify the existence of attributes in both of them, although the English term itself is not actually being used by Korean linguists, and thus might not be well known. Nevertheless, since the function of gwanhyeongeo (Kor. 관형어) in Korean, and attributes in Polish is similar, for the sake of transparency, this particular term will be used.The aim of this article is to propose a comprehensive classification of attributes in both target languages based on formal, syntactic and semantic parameters. In order to do it in the most exhaustive way, firstly different approaches concerning the definition of attributes, as well as the methods of their classification, proposed by various linguists in both languages will be examined. The author hopes to find out to which extent the typological differences between Korean and Polish are reflected in the attributes’ properties, according to which they can be classified.

Machine learning workflow development is a process of trial-and-error: developers
iterate
on workflows by testing out small modifications until the desired accuracy is achieved. Unfortunately, existing machine learning systems focus narrowly on model training---a small fraction of the overall development time---and neglect to address iterative development. We propose H
elix
, a machine learning system that
optimizes the execution across iterations
---intelligently caching and reusing, or recomputing intermediates as appropriate. H
elix
captures a wide variety of application needs within its Scala DSL, with succinct syntax defining unified processes for data preprocessing, model specification, and learning. We demonstrate that the reuse problem can be cast as a M
ax
-F
low
problem, while the caching problem is NP-H
ard
. We develop effective lightweight heuristics for the latter. Empirical evaluation shows that H
elix
is not only able to handle a wide variety of use cases in one unified workflow but also much faster, providing run time reductions of up to 19x over state-of-the-art systems, such as DeepDive or KeystoneML, on four real-world applications in natural language processing, computer vision, social and natural sciences.
Fast approximate nearest neighbor search with the navigating spreading-out graph
Authors: Fu Cong , Xiang Chao , Wang Changxu , Cai Deng
Published: February 2019

Approximate nearest neighbor search (ANNS) is a fundamental problem in databases and data mining. A scalable ANNS algorithm should be both memory-efficient and fast. Some early graph-based approaches have shown attractive theoretical guarantees on search time complexity, but they all suffer from the problem of high indexing time complexity. Recently, some graph-based methods have been proposed to reduce indexing complexity by approximating the traditional graphs; these methods have achieved revolutionary performance on million-scale datasets. Yet, they still can not scale to billion-node databases. In this paper, to further improve the search-efficiency and scalability of graph-based methods, we start by introducing four aspects: (1) ensuring the connectivity of the graph; (2) lowering the average out-degree of the graph for fast traversal; (3) shortening the search path; and (4) reducing the index size. Then, we propose a novel graph structure called Monotonic Relative Neighborhood Graph (MRNG) which guarantees very low search complexity (close to logarithmic time). To further lower the indexing complexity and make it practical for billion-node ANNS problems, we propose a novel graph structure named Navigating Spreading-out Graph (NSG) by approximating the MRNG. The NSG takes the four aspects into account simultaneously. Extensive experiments show that NSG outperforms all the existing algorithms significantly. In addition, NSG shows superior performance in the E-commercial scenario of Taobao (Alibaba Group) and has been integrated into their billion-scale search engine.
Analyzing efficient stream processing on modern hardware

Modern
Stream Processing Engines
(SPEs) process large data volumes under tight latency constraints. Many SPEs execute processing pipelines using message passing on shared-nothing architectures and apply a partition-based
scale-out
strategy to handle high-velocity input streams. Furthermore, many state-of-the-art SPEs rely on a Java Virtual Machine to achieve platform independence and speed up system development by abstracting from the underlying hardware.

In this paper, we show that taking the underlying hardware into account is essential to exploit modern hardware efficiently. To this end, we conduct an extensive experimental analysis of current SPEs and SPE design alternatives optimized for modern hardware. Our analysis highlights potential bottlenecks and reveals that state-of-the-art SPEs are not capable of fully exploiting current and emerging hardware trends, such as multi-core processors and high-speed networks. Based on our analysis, we describe a set of design changes to the common architecture of SPEs to
scale-up
on modern hardware. We show that the single-node throughput can be increased by up to two orders of magnitude compared to state-of-the-art SPEs by applying specialized code generation, fusing operators, batch-style parallelization strategies, and optimized windowing. This speedup allows for deploying typical streaming applications on a single or a few nodes instead of large clusters.
Meta-mappings for schema mapping reuse

Published: February 2019

The definition of mappings between heterogeneous schemas is a critical activity of any database application. Existing tools provide high level interfaces for the discovery of correspondences between elements of schemas, but schema mappings need to be manually specified every time from scratch, even if the scenario at hand is similar to one that has already been addressed. The problem is that schema mappings are precisely defined over a pair of schemas and cannot directly be reused on different scenarios. We tackle this challenge by generalizing schema mappings as
meta-mappings:
formalisms that describe transformations between generic data structures called
meta-schemas.
We formally characterize schema mapping reuse and explain how meta-mappings are able to: (i) capture enterprise knowledge from previously defined schema mappings and (ii) use this knowledge to suggest new mappings. We develop techniques to infer meta-mappings from existing mappings, to organize them into a searchable repository, and to leverage the repository to propose to users mappings suitable for their needs. We study effectiveness and efficiency in an extensive evaluation over real-world scenarios and show that our system can infer, store, and search millions of meta-mappings in seconds.
Adaptive optimistic concurrency control for heterogeneous workloads

Optimistic concurrency control (OCC) protocols validate whether a transaction has conflicts with other concurrent transactions after this transaction completes its execution. In this work, we demonstrate that the validation phase has a great influence on the performance of modern in-memory database systems, especially under heterogeneous workloads. The cost of validating operations in a transaction is determined by two main factors. The first factor is the operation type. An OCC protocol would take much less cost on validating a single-record read operation than validating a key-range scan operation. The second factor is the workload type. Existing schemes in OCC variants for validating key-range scan perform differently under various workloads.

Although various validation schemes share the same goal of guaranteeing a transaction schedule to be serializable, there are remarkable differences between the costs they introduced. These observations motivate us to design an optimistic concurrency control which can choose a low-cost validation scheme at runtime, referred to as adaptive optimistic concurrency control (AOCC). First, at transaction-level granularity, AOCC can assign a validation method to a transaction according to the features of its operations. Furthermore, for each operation in a transaction, the validation method is selected according to not only the number of accessed records but also the instant characteristics of workloads. Experimental results show that AOCC has good performance and scalability under heterogeneous workloads mixed with point accesses and predicate queries.

Recent
deterministic database systems
have achieved high scalability and high availability in distributed environments given OLTP workloads. However, modern OLTP applications usually have changing workloads or access patterns, so how to make the resource provisioning elastic to the changing workloads becomes an important design goal for a deterministic database system.
Live migration,
which moves the specified data from a source machine to a destination node while continuously serving the incoming transactions, is a key technique required for the elasticity. In this paper, we present MgCrab, a live migration technique for a deterministic database system, that leverages the
determinism
to maintain the consistency of data on the source and destination nodes at very low cost during a migration period. We implement MgCrab on an open-source database system. Extensive experiments were conducted and the results demonstrate the effectiveness of MgCrab.
Modified 30-Second Sit-to-Stand Test: Reliability and Validity in Older Adults Unable to Complete Traditional Sit-to-Stand Testing
Authors: McAllister Linda S. , Palombaro Kerstin M.
Published: February 2019

Background and Purpose:

Sit-to-stand tests measure a clinically relevant function and are widely used in older adult populations. The modified 30-second sit-to-stand test (m30STS) overcomes the floor effect of other sit-to-stand tests observed in physically challenged older adults. The purpose of this study was to examine interrater and test-retest intrarater reliability for the m30STS for older adults. In addition, convergent validity of the m30STS, as well as responsiveness to change, was examined in older adults undergoing rehabilitation.

Methods:

In phase I, 7 older adult participants were filmed performing the m30STS. The m30STS was standardized to allow hand support during the rise to and descent from standing but required participants to let go of the armrests with each stand. Ten physical therapists and physical therapist assistants independently scored the filmed m30STS twice, with 21 days separating the scoring sessions. In phase II, 33 older adults with comorbidities admitted to physical therapy services at a skilled nursing facility were administered the m30STS, Berg Balance Scale, handheld dynamometry of knee extensors, and the modified Barthel Index at initial examination and discharge.

Results:

In phase I, the m30STS was found to be reliable. Interrater reliability using absolute agreement was calculated as intraclass correlation coefficient (ICC)2,1 = 0.737 (P ≤ .001). Test-retest intrarater reliability using absolute agreement was calculated as ICC2,k = 0.987 (P ≤ .001). In phase II, concurrent validity was established for the m30STS for the initial (Spearman ρ = 0.737, P = .01) and discharge (Spearman ρ = 0.727, P = .01) Berg Balance Scale as well as total scores of the modified Barthel Index (initial total score Spearman ρ = 0.711, P = .01; discharge total score Spearman ρ = 0.824, P = .01). The initial m30STS predicted 31.5% of the variability in the discharge Berg Balance Scale. The m30STS did not demonstrate significant correlation with body weight–adjusted strength measures of knee extensors measured by handheld dynamometry. The minimal detectable change (MDC90) was calculated to be 0.70, meaning that an increase of 1 additional repetition in the m30STS is a change beyond error.

Conclusion:

The m30STS is a reliable, feasible tool for use in a general geriatric population with a lower level of function. The m30STS demonstrated concurrent validity with the Berg Balance Scale and modified Barthel Index but not with knee extensor strength to body weight ratio. One repetition of the m30STS was established as the MDC90 as change beyond error.
Potential Reuse of Treated Textile Effluent in Fly Ash Concrete

Published: February 2019

In a preliminary effort to deal with the present fresh water demand in the construction industry, this article examines the potential reuse of textile effluent as mixing water in making fly ash concrete. The effluents were collected from a textile industry at different stages of treatment, such as Collection Tank Effluent, Effluent after Anaerobic Treatment (EAT), Tertiary Treatment Effluent, and Reverse Osmosis Feed Effluent. The collected effluent samples have been analyzed to establish physicochemical characteristics and their effects on the properties of concrete, such as compressive strength, split tensile strength, and flexural strength. Higher salt content in effluent mix water significantly increased the final setting time of the binder. Furthermore, the workability of the concrete made with effluent mix water is relatively higher than that of the control concrete mix. Also, concrete mixes made with textile effluent mix water demonstrated greater strength than that of the control concrete. Furthermore, EAT mixes have exhibited maximum compressive strength compared with other mixes and also had superior durability compared with the control concrete mix. The higher strength can be attributed to the nucleation effect caused by the presence of a high concentration of total solids in the effluent. However, this concrete can be recommended for applications of plain cement concrete, such as pavements, industrial floors, and curbs/gutters.
Afghanistan in 2018

Published: February 2019

Three aspects symbolize the state of affairs in and around Afghanistan in 2018: the fragmentation of domestic political actors, the increasing desecuritization of rhetoric with respect to Afghanistan by neighboring countries, and the diversification of Afghanistan’s global partners. While the US strategy showed signs of stalling amid increasing violence and the fragmentation of local actors, there are changes in the attitude of neighboring states.

Russia’s “Asian pivot” remains focused on China, despite energetic Russian diplomacy in 2018 vis-à-vis Japan and India. The benefits of the enlargement of the Shanghai Cooperation Organisation to include Pakistan and India remained unclear, and the overlapping memberships of regional organizations highlighted the challenges for security and economic cooperation in Central Asia.
MANAGEMENT OF ENDOCRINE DISEASE: Childhood-onset craniopharyngioma: state of the art of care in 2018
Authors: Müller Hermann L
Published: February 2019

This review presents an update on current concepts of pathogenesis, diagnostics, multidisciplinary treatment and follow-up care, with special focus on neuropsychological sequelae of childhood-onset craniopharyngioma (CP) based on most recent publications on these topics. Recent insight in molecular pathogenesis of CP opens new perspectives on targeted therapy. Further research to elucidate pathogenic mechanisms and to prevent hypothalamic involvement of CP is warranted. Surgical treatment strategies should be based on a multidisciplinary approach involving experienced teams aiming at posterior hypothalamus-sparing treatment for prevention of quality of life impairments. Centralization of CP treatment in experienced ‘centers of excellence’ is recommended. However, such centralization includes high thresholds concerning infrastructure not achievable in all health systems. Alternatives such as multicenter-based networks used for reference assessments should be considered to assure high standards of treatment quality. Irradiation is efficient in preventing further growth or recurrence in CP patients with residual tumor. Proton beam therapy – available on a wider range in the near future – will help to avoid radiooncological side effects. Novel insights into neuropsychological sequelae after CP should be the basis for the development of future therapeutic neuropsychological interventions. Due to the rareness of the disease, common international efforts in research and treatment are recommended and should lead to an international registry for childhood-onset CP, as a first step toward efficient coordination of scientific and clinical initiatives.
Transcriptional status of mouse oocytes corresponds with their ability to generate Ca2+ release

Published: February 2019

In fully grown ovarian follicles both transcriptionally active (NSN) and inactive (SN) oocytes are present. NSN oocytes have been shown to display lower developmental potential. It is possible that oocytes that have not completed transcription before meiosis resumption accumulate less RNA and proteins required for their further development, including those responsible for regulation of Ca2+homeostasis. Oscillations of the cytoplasmic concentration of free Ca2+ions ([Ca2+]i) are triggered in oocytes by a fertilizing spermatozoon and are crucial for inducing and regulating further embryonic development. We showed that NSN-derived oocytes express less inositol 1,4,5-triphosphate receptor type 1 (IP3R1), store less Ca2+ions and generate weaker spontaneous [Ca2+]ioscillations during maturation than SN oocytes. Consequently, NSN oocytes display aberrant [Ca2+]ioscillations at fertilization. We speculate that this defective regulation of Ca2+homeostasis might be one of the factors responsible for the lower developmental potential of NSN oocytes.
