Authors: Knopik Tomasz , Oszwa Urszula , Domagała-Zyśk Ewa
Published: September 2019

The article discusses existing ways of recognising functional diagnosis in theoretical models in the field of psycho-pedagogy. It also examines strategies for the use of these models in diagnostic and therapeutic activities. By systematising the collected information, the authors describe goals, stages and features of functional diagnosis. In addition, they propose a synthetic definition that takes into account contemporary trends in psychological and pedagogical counselling. The article presents an example of application of the functional diagnosis model in the emotional and social spheres, the original psycho-pedagogical diagnostic tool TROS-KA, which was standardised in a group of 1,227 Polish students.
Rola duszpasterstwa więziennego w resocjalizacji penitencjarnej, w kontekście badań własnych i dyskursu naukowego
Authors: Pierzchała Kazimierz
Published: September 2019

Although the legislator in the applicable legal regulations did not call the pastoral activity “penitentiary activity” and did not include this activity in the catalogue of means of penitentiary influence, practical experience shows that the tasks of the prison chaplain and other people involved in the work of penitentiary priesthood are analogous to penitentiary work, having a specific social rehabilitation dimension. They are also an important element of postpenitentiary interactions aimed at social reintegration of prisoners. Significant words fell from the then director of the Central Board of Criminal Offices, Paweł Moczydłowski, during the ceremony of dedicating the prison chapel in Chełm in June 1990: “Here the Church today is permanently entering the prison system. We cannot imagine a new prison without the presence of the Church and its moral teachings. Repression is to replace – justice, hatred – humanism and a good word, including evangelical” (Harasiuk 1990: 5).

THE EFFECT OF THE TYPE OF WALL MATERIAL AND GREASE
COMPOSITION PAIRING ON SHEAR STRESSES IN BOUNDARY
LAYER
Authors: Czarny Ryszard
Published: September 2019

The paper presents the results of research on the influence of fillers introduced into plastic greases on the
rheological properties of the boundary layer of the resultant lubricant compositions. The fillers were PTFE
and MoS2 powders. They are added to lubricants to improve their tribological properties; however, these
fillers also affect the rheological properties of the composition. This affects the change of the shear stress
value in the lubricant during its flow in the lubrication system. Knowledge of this value, especially during the
flow of the lubricant composition in the boundary layer, has a significant impact on the operation of automated
central lubrication systems in which these compositions can be used. Measurements were carried out by
means of a rotary rheometer (Rheotest 2.1). Tests were performed on lithium and bentonite greases (without
additives) as well as compositions of these greases containing various percentage of the fillers mentioned
above. Test results showed that both the type of grease and the type of filler introduced into this grease affect
the rheological properties in the boundary layer of the produced lubricating compositions.

Authors: Ligier Krzysztof , Lemecha Magdalena , Napiórkowski Jerzy
Published: September 2019

This paper presents the results of tests for Hardox Extreme Steel wear rate in an abrasive mass of varying
moisture contents. The tests were conducted by the “rotating bowl” method using quartz sand with a grain size
of 0.5–1.4 mm. The obtained test results show that an abrasive mass with a moisture content of 7% exhibits
the lowest rate of steel abrasive wear. However, the highest wear rate was noted for an abrasive mass with
a moisture content of 14%. A further increase in moisture content resulted in a decrease in the steel wear rate.

Published: September 2019

Problema: Os direitos fundamentais das pessoas transgênero são negados cotidianamente. Neste cenário, o preconceito age como determinante social de saúde impactando na prevalência de problemas como saúde mental e infecções sexualmente transmissíveis (ISTs). O objetivo foi o desenvolvimento de um sumário de evidências para apoiar o atendimento clínico e embasar a capacitação dos profissionais da Atenção Primária de Saúde de Florianópolis - SC, a fim de melhorar os resultados de saúde dessa população. Métodos: Baseado na ferramenta PACK – interface acessível e intuitiva no modelo pergunte, solicite, aconselhe e trate – já implementada no município de Florianópolis. O método de revisão rápida foi utilizado para busca de evidência, priorizando sumários de prática clínica e protocolos internacionais. Fontes primárias foram utilizadas quando os dados anteriores eram insuficientes ou conflitantes. As perguntas de pesquisa seguiram o acrônimo PICO e a recomendação foi classificada de acordo com a adaptação GRADE do Center of Excellence for Transegender Health. Resultados: Foi criado o Guia Rápido para Prática de Atenção à Saúde da População Transgênero aos moldes do PACK Brasil. O mesmo aguarda aprovação do PACK Brasil e do Ambulatório de Atenção Integral à População Transexual de Florianópolis para futura incorporação do material. Conclusão: Apesar da falta de evidência de qualidade e estudos voltados para a população específica, a existência de diretrizes nesse campo legitima a necessidade de atenção à saúde transgênero, além de auxiliar profissionais de saúde e formuladores de políticas sobre como atender a essas necessidades. Na perspectiva de redução de danos, devemos transpor a barreira do estigma social e institucional para produção de diretrizes consensuais em busca de equidade para população transgênero.

Authors: Myazin Nikita Sergeevich , Davydov Vadim Vladimirovich , Yushkova Victoria Valerevna , Rud' Vasiliy Yurevich
Published: September 2019

Paper discusses the technique of environmental condition monitoring based on the phenomenon of nuclear magnetic resonance (NMR). Express control is an integral part of agriculture, because when working on farms or in fields there are situations when it is physically impossible to deliver samples for research to a stationary laboratory (results are needed urgently or samples can change their properties during transportation). A brief review of the existing methods for monitoring the states of media in the express mode was carried out, their shortcomings were revealed and a new technical solution to this problem was proposed. For a small-sized NMR spectrometer, a new magnetic system and a signal registration circuit have been developed, which makes it possible to detect the NMR signal at different frequencies, thus registering the signal spectrum. In addition, this design also allows measuring the longitudinal and transverse relaxation times of the medium. With the help of the proposed technique, studies of various media have been carried out; the results of these studies are presented.

Published: September 2019

The Kyiv city is the capital of Ukraine, as well as its major administrative and industrial center. Kyiv is located in the middle reaches of the Dnipro River which is the largest river in Ukraine. In the past, the Kyiv city suffered from dangerous spring floods. Consequently, long-term forecasting of spring floods on the Dnipro River near Kyiv has an important scientific and practical significance. Existing quantitative methods for such forecasting are of limited forecast lead time and require many input hydrometeorological data. In the paper the information method Weng Wen-Bo applied, which is a qualitative forecasting method. The use such method allows to determine the periods and specific years in which the following extraordinary spring floods on the Dnipro River near Kyiv can occur.

Abstract: Adaptive development and executive functioning in children with diagnosis of conduct disorder and attention-deficit/hyperactivity disorder hyperactive/impulsive type. Adaptive development allows the subject emotional control, disposition towards new challenges and the expected socio-cognitive adjustment contextually, facilitating learning and executive and social functioning. The objective of the study was to determine executive-adaptive development in children with diagnostic criteria or conduct disorder (CD) or attention deficit hyperactive-impulsive type disorder (ADHD-I). With clinical instruments to identify diagnostic criteria for each nosology, 80 children were classified in control group (30), CD (34) or ADHD-I (16). Based on multinomial logistic regression, Kruskal Wallis, and χ2 tests, we found that an appropriate sleep, persistence in tasks, and academic achievement seem to act as protective factors for the clinical samples. Difficulties were observed in sequential planning, where the CD group presented better metacognitive control than ADHD-I. It was concluded that school environment provides factors to improve clinical symptomatology.Keywords: Adaptive factors; executive functions; attention deficit/hyperactivity disorder; conduct disorder; adaptive development.Resumen: El desarrollo adaptativo permite al sujeto el control emocional, la disposición hacia nuevos retos y el ajuste socio-cognitivo esperado contextualmente, facilitando el aprendizaje, funcionamiento ejecutivo y social.

Published: September 2019

Introduction: Malnutrition has a significant impact on global disease for the majority of children worldwide, by being responsible for almost half of the deaths of children under the age of five especially in the developing countries including Eritrea. However, there is no clear information on the role of antenatal care and feeding practices in preventing malnutrition. Therefore, assessing the role of antenatal care visit and feeding practices in preventing malnutrition is of vital importance.
Objective: To assess the role of regular ANC visit and feeding practices in preventing malnutrition among children aged 0-59 months, who visited Orotta National Pediatric Referral Hospital from 31st August – 30th September, 2016.
Methodology: A cross-sectional, Hospital based study was carried out. Data were collected from mothers (caretakers) using semi-structured questionnaire developed for the purpose. Moreover, anthropometric measurement of the subjects was taken. Data was and entered to the computer and analyzed using SPSS version 20 and p-value <0.05 at 95%CI was considered as statistically significant.
Results: The main associated factors of stunting were found to be the frequency of breastfeeding and antenatal care visit. Underweight was associated with weaning of breastfeeding. Frequency of breastfeeding and weaning of breastfeeding were the only variables associated with wasting.
Conclusion and Recommendation: Malnutrition remains a major health problem among children aged 0-59 months. Hence, interventions regarding regular antenatal care visits and feeding practices are highly suggested to be given special attention.

Authors: Rodrigues Luciana Lavareda , Blanco Claudio José Cavalcante
Published: September 2019

Os efeitos da urbanização sobre o aumento da vazão de pico e escoamento superficial da bacia hidrográfica do igarapé do Urumari em Santarém/PA foram analisados. O uso do solo é determinante para o dimensionamento da rede de drenagem pluvial, tendo em vista que as áreas mais impermeabilizadas acarretam maior escoamento superficial e vazão de pico. Assim, foram simulados três cenários de uso do solo: 1960, 2017 e um cenário futuro. Foram determinadas as porcentagens de área impermeabilizada de cada época, através de mapas gerados em ambiente SIG, imagens de satélite e adaptação de mapas no software DraftSight 2018. A partir do método SCS (Soil Conservation Service), calcularam-se os parâmetros necessários para a geração dos hidrogramas de cheia dos três cenários. Os resultados mostraram que o processo de urbanização tem efeito significativo sobre as vazões de pico de bacias hidrográficas urbanas, o que pode ser visto claramente nos hidrogramas de cheia apresentados. Nesse caso, o cenário futuro, por ter maior impermeabilização do solo, apresentou uma vazão de pico 2,24 vezes maior que a vazão de pico do cenário de 2017 e 6,80 vezes maior que a do cenário de 1960. Esses resultados servem de alerta para os gestores municipais no que se refere ao planejamento e controle das políticas urbanas em relação à rede de drenagem de águas pluviais, que deve ser norteada em concordância com os estudos da expansão urbana.
Usage of Rotary Instruments in Root Canal Therapy of Deciduous Teeth - Review
Authors: KIRMIZIGÜL İnci , DEMİR Pınar
Published: September 2019

Maintaining the deciduous teeth in the mouth until
the time of physiological exfoliation is of great importance for the health of
the permanent dentition. Root canal treatment, also called pulpectomy,
performed in cases of inflammation or necrosis of the deciduous teeth pulp, is
indicated as a successful method to preserve the tooth functionally. Conventional
pulpectomy procedure is performed with stainless steel files, however, the low
elasticity of these files may cause undesirable canal shapes and the
time-taking treatment period may lead to deterioration of the patient's
cooperation, especially in pedodontics. Ni-Ti rotary instrument systems
eliminate these disadvantages and provide better quality canal fillings in a
shorter duration. The present article reviewed the studies that are comparing
the traditional stainless steel files and Ni-Ti rotating instrument for the
root canal treatment of deciduous teeth.

Objective: Male infertility is a scourge of the 21st century. Its management remains a real headache. The objective of this study is to describe the general profile of male infertility at the IRIFIV In Vitro Fertilization Center, Casablanca, Morocco.

Materials and Methods: This is a retrospective and descriptive study of 295 patient files seen in consultation for conjugal infertility of the couple between 2017 and 2018. The parameters studied were clinical elements and paraclinical explorations.

Results: The average age of the patients was 37.5 years. The average duration of evolution of infertility was 5.5 years. Infertility was primary in 70.9% of cases and secondary in 29.1% of cases. Clinically, varicocele was the most common abnormality in 65.9% of patients. The seminogram was disrupted in 72% of cases. The main disturbances were oligozoospermia in 40.20% of cases and asthenozoospermia in 37% of cases.

Conclusion: The general profile of infertility is polymorphic. The causes of male infertility noted are multifactorial. Male infertility usually results in a quantitative and/or qualitative abnormality of the sperm. The improvement of the management of infertility must go through new ways of research including genetic and immunological for a good identification of usually hidden causes of infertility.

Published: September 2019

It is desirable to design nonprecious metal nanocatalysts with high stability and catalytic performance for fine chemicals production. Here, a method is reported for the preparation of cobalt metal and cobalt oxide cores confined within nanoporous nitrogen‐doped hollow carbon capsules. Core–shell structured Zn/Co‐ZIF@polymer materials are fabricated through a facile coating polymer strategy on the surface of zeolitic imidazolate frameworks (ZIF). A series of hollow carbon capsules with cobalt metal and cobalt oxide are derived from a facile confined pyrolysis of Zn/Co‐ZIF@polymer. The hollow Co‐CoOx@N‐C capsules can prevent sintering and agglomeration of the cobalt nanoparticles and the nanoporous shell allows for efficient mass transport. The specific surface area and Co particle size are optimized through finely tuning the original Zn content in ZIF particles, thus enhancing overall catalytic activity. The yolk–shell structured Zn4Co1Ox@carbon hollow capsules are shown to be a highly active and selective catalyst (selectivity >99%) for hydrogenation of nitrobenzene to aniline. Furthermore, Zn4Co1Ox@carbon hollow particles show superior catalytic stability, and no deactivation after 8 cycles of reaction. The hollow Co‐CoOx@N‐C capsules may shed light on a green and sustainable catalytic process for fine chemicals production.

Published: September 2019

Lithium (Li) metal is one of the most promising anode materials to construct next‐generation rechargeable batteries owing to its ultrahigh theoretical capacity and the lowest electrochemical potential. Unfortunately, practical application of Li metal batteries is severely hindered by short lifespan and safety concerns caused by Li dendrite growth during cycling. Herein, a coaxial‐interweaved hybrid Li metal anode is proposed for dendrite inhibition that significantly improves the cycling stability of Li metal batteries. The hybrid Li metal anode is fabricated by Li composition into a 3D interweaved scaffold, where each fiber of the interwoven scaffold is composed of a conductive skeleton and a coaxial lithiophilic layer modified on the surface. The coaxial‐interweaved structure endows the hybrid anode with favored Li affinity to guide uniform Li deposition, sufficient channels for ion transportation and electron conduction, and enhanced stability during Li plating and stripping. Consequently, the hybrid Li metal anode affords high Coulombic efficiency over 98.5% for 750 cycles with dendrite‐free morphologies in half cells and improved capacity retention of 80.1% after 100 cycles in LiFePO4 full cells. The innovative coaxial‐interweaved hybrid Li metal anode demonstrates multiscale design strategy from lithiophilic modification to scaffold construction and promises the prospect of Li metal batteries for future applications.

Published: September 2019

Due to the obvious advantages of utilizing naturally abundant and low cost sodium resources, sodium ion batteries (SIBs) show great potential for large‐scale energy storage applications. And the high theoretical capacities of transition metal sulfides (TMSs) make them appealing anode materials for SIBs; however, structural collapse caused by the severe volume change during de/sodiation processes results in poor capacity retention and rate capabilities. Compared to the development of new materials and the improvement of their electrochemical performance, the studies on their reaction mechanisms are still rare, especially the operando characterizations. Herein, the synthesis, anode application, and the operando observation of the de/sodiation mechanism of a nitrogen‐doped porous carbon coated nickel cobalt bimetallic sulfide hollow nanocube ((Ni0.5Co0.5)9S8@NC) composite are reported. Such a material is synthesized via facile sulfidation of phenol formaldehyde coated Ni3[Co(CN)6]2 metal–organic framework precursors with Na2S followed by calcination. The nanocomposite displays a remarkable specific capacity of 752 mAh g−1 at 100 mA g−1 after 100 cycles and outstanding rate capability due to the synergistic effect of several appealing features. Particularly, the pseudocapacitive effect appears to substantially contribute to the sodium storage capability. Operando X‐ray diffraction reveals the conversion reaction mechanism of (Ni0.5Co0.5)9S8@NC, forming Ni, Co, Na2S, and Na2S5.

Centralized and decentralized distributed control of longitudinal vehicular platoons with non‐uniform communication topology
Authors: Chehardoli Hossein , Ghasemi Ali , Najafi Ali
Published: September 2019

In this paper, the distributed control of a longitudinal platoon of vehicles with non‐uniform communication topology is studied. In the case of non‐uniform communication topology, some eigenvalues of the network's matrix may be complex which complicates the stability analysis of the platoon. Most previous studies on vehicular platooning focus mainly on uniform topologies such as uni‐directional, bi‐directional, and multi predecessors following. Since all eigenvalues of these topologies are real, the stability analysis can be performed in a straightforward manner. A third‐order linear differential model is employed to describe the upper‐level dynamics of each vehicle. The 3 N‐order closed‐loop dynamics of the platoon are decoupled to individual third‐order dynamics by presenting a new approach. Two new centralized and decentralized control protocols are introduced to perform the stability analysis of the closed‐loop dynamics. A constant time headway strategy is employed to adjust the inter‐vehicle spacing. Simulation results with different scenarios are presented to illustrate the effectiveness of the proposed approaches.

High‐valent cobaltIV‐bpy complex stabilized in silica matrix was detected as catalytically active form and intermediate in cobalt‐mediated oxidative C−H/NH cross‐coupling reaction. These CoIV species prepared by electrooxidation of CoIII(bpy)3‐doped silica nanoparticles (SNs) at relatively low anodic potentials have demonstrated high catalytic activity. Both size and architecture of the SNs are highlighted as the factors beyond the complex structure affecting its oxidation potential and catalytic efficiency. The factors have been optimized for the catalyst with high efficiency, easy separation and reusability for 7 times at least. The optimal nanocatalyst (1 mol%) provides 100 % conversion of reactants in a single step of ligand‐directed coupling of H2NTs with arenes under electrochemical regeneration conditions. The results emphasize both synthetic route for efficient embedding of CoIII(bpy)3 into silica support and the electrochemical generation of CoIV complexes as a facile route for developing the efficient nanocatalyst of oxidative functionalization. The observed reactivity has the potential in development of Co‐catalyzed coupling reactions.

Authors: Theßeling Christin , Grünewald Marcus
Published: September 2019

In experimentellen Versuchen wurde die Genauigkeit eines Leitfähigkeits‐Gittersensors mit einer zeitlichen und räumlichen Auflösung von 5 kHz und 4,8 mm in Bezug auf die Bestimmung von Blasengrößen untersucht. Als Referenzwert werden einzelne Luftblasen definierten Gasvolumens im Größenbereich von 2 – 12 mm in eine ruhende Flüssigkeit aufgegeben. Die Ergebnisse zeigen eine erhöhte Messunsicherheit für Blasen, deren Durchmesser kleiner als die Auflösung des Gitternetzes ist. Die ermittelte Blasengröße hängt in diesem Fall stark von der örtlichen Position der aufsteigenden Gasblasen im Gitternetz ab.
How pressure from stakeholders affects integrated reporting quality
Authors: Vitolla Filippo , Raimo Nicola , Rubino Michele , Garzoni Antonello
Published: September 2019

Integrated reporting (IR) is considered an innovative and effective reporting tool that includes financial and nonfinancial information. Recently, there has been a heightened emphasis on IR from both academic and professional viewpoints. However, despite the importance of stakeholders in the practice of IR, their impact on the report drafting process has not been analysed in any study. Therefore, this study aims to fill this gap by analysing the relationship between stakeholders' pressure and IR quality. On the basis of the stakeholder theory, this study uses a regression model to demonstrate how the IR quality is significantly and positively associated with the stakeholders' pressures. Specifically, results of this study indicate that pressures from customers, environmental protection organizations, employees, shareholders, and governments determine the IR quality. To the best of our knowledge, this is the first study that investigates stakeholders' pressure as a determinant of IR quality.
Recruiting millennials: Exploring the impact of CSR involvement and pay signaling on organizational attractiveness
Authors: Waples Christopher J. , Brachle Benjamin J.
Published: September 2019

Modern organizations must consider corporate social responsibility (CSR) and its implications. CSR involvement carries many potential benefits, including opportunities to promote stakeholder engagement with the organization, particularly among young people (i.e., millennials) in the emergent workforce. Collectively, millennials are often described as both socially active and self‐centered. These seemingly antithetical motives complicate the execution of optimal recruitment practice. This empirical study examined the impact of CSR activity and relative pay level signals on organizational attractiveness. Participants who were seeking or soon to be seeking employment in the United States responded to a hypothetical company profile. Confirming expectations, results revealed an effect of CSR information on organizational attractiveness, wherein notification of CSR involvement enhanced attractiveness. Pay level and CSR notification did not significantly interact, indicating that the effects of CSR on attractiveness are not moderated by information about pay levels. The implications of the results and future research recommendations are discussed.
Corporate social responsibility and firm value: Do firm size and age matter? Empirical evidence from European listed companies
Authors: D'Amato Antonio , Falivena Camilla
Published: September 2019

Although the current empirical literature has focused predominantly on the direct relationship between corporate social responsibility (CSR) and firm value, in this paper, we aim to explore firm‐level moderators that may contribute to disentangling this relationship. On the basis of a dataset of Western European listed companies, we use a moderation analysis of panel data to examine whether firm size and age drive the impact of CSR on firm value. Our estimations show that the relationship between CSR and firm value is moderated by firm size and age so that it is negatively impacted when small and/or young companies are considered. This finding seems to be consistent with the view that CSR initiatives could be ineffective in smaller and younger companies due to their lack of financial resources, experience, reputation, and so forth. Implications for firms are also discussed.
A longitudinal examination of the relationship between eating disorder symptoms and suicidal ideation
Authors: Ortiz Shelby N. , Smith April
Published: September 2019

Objective

Cross‐sectional research demonstrates significant correlations between eating disorders (EDs) and suicidal thoughts and behaviors. Although suicide ideation (SI) is a risk factor for suicidal behavior, longitudinal research investigating SI among EDs is limited. Thus, the aim of this study was to offer insight into the dynamic relationship between EDs and SI by investigating if these variables predicted one another at weekly time points.

Method

Autoregressive cross‐lagged modeling was used to test bidirectional relationships between ED symptoms and suicidal ideation among an ED patient sample (n = 92). Participants completed a measure of suicidal ideation and the Eating Disorder Examination—Questionnaire (EDE‐Q) weekly for 5 weeks.

Results

SI and ED symptoms were correlated with each other at each time point. Unexpectedly, the majority of cross‐lagged pathways were nonsignificant. However, SI at Week 4 predicted ED symptoms at Week 5, while controlling for Week 4 ED symptoms. This pattern of results was found when the shape concerns, weight concerns, and eating concerns subscales of the EDE‐Q were entered into the model. Moreover, Week 2 shape concerns predicted Week 3 SI and Week 3 eating concerns predicted Week 4 SI. No significant cross‐lagged pathways were found with the dietary restraint subscale.

Discussion

Nonsignificant cross‐lagged pathways may indicate that third variables better explain the relations between certain ED symptoms and SI over time. However, there were instances where ED symptoms and SI predicted one another. Given this, targeting suicidal thoughts in therapy may help to reduce eating pathology and vice versa.
Effects of self‐control training for elementary students with emotional and behavioral disorders
Authors: Staubitz Johanna L. , Lloyd Blair P. , Reed Derek D.
Published: September 2019

Progressive delay training (PDT) has been used to promote self‐controlled choices (i.e., selecting a larger, later reward over a smaller, immediate reward) for people with a variety of developmental characteristics. However, the efficacy of PDT has not been evaluated in children with emotional and behavioral disorders (EBD), who often have co‐occurring symptoms of impulsivity. The purpose of this study was to evaluate the effects of PDT with a rule‐following requirement on the impulsive choices of 6 elementary students with EBD using a modified changing criterion design. Results indicated that PDT alone did not improve self‐control, but a modified version of PDT with a rationale and rule for selecting the delayed reward promoted self‐control for 3 participants. The remaining 3 participants continued to make impulsive choices despite further modifications to the PDT protocol. We discuss implications of our results and directions for future research on treating impulsivity in children with EBD.

Published: September 2019

Background

It is estimated about 7% of the world population is carriers of hemoglobin diseases. Alpha‐thalassemia is one of the most common hereditary hemoglobin disorders in the world. This study investigated alpha‐globin mutations in potential carriers with hypochromic and microcytic anemia from Mazandaran, in northern Iran.

Methods

A total of 859 subjects were selected; genomic DNA was extracted and examined for the presence of mutations in the alpha‐globin genes.

Results

Mutation analysis of alpha‐globin genes revealed 27 different mutations. Seven variants were seen in 91.45% of all alpha‐1 and alpha‐2 mutations among patients in this study. The 3.7 kb deletion is the most frequent mutation with a frequency of 49.53%, followed by PolyA2 (15.19%), −4.2 deletion (8.76%), ‐‐MED (5.84%), IVSI‐5nt deletion (5.49%), Hb constant spring (3.62%), and Cd 19 (−G; 3.04%), respectively. There are also seven new variants which were reported for the first time either in alpha‐1 or alpha‐2 genes, including codon 9 (C > A; α2), deletion of codon 60 (AAG deletion; α2), duplication of codon 94‐100 plus 3 base pairs of intron 2 (IVSII + 3; α1), codon 99 (C > A; α2), codon 108 (A > G; α2), codon 128 (A > T; α2), and codon 129 (T > G; α2), respectively. The MLPA method also revealed three rare and novel deletions in alpha‐cluster region with about 30 kilobases long.

Conclusion

This study showed an efficient identification of α‐thalassemia can be achieved using standard hematological indices in our population. The details of these variations will help local genetic services for diagnostic and prenatal diagnosis services.
Schiff base derived from salicylaldehyde‐based azo dye as chromogenic anionic sensor and specific turn‐on emission sensor for cyanide ion
Authors: Chakraborty Nilanjan , Chakraborty Arijit , Das Suman
Published: September 2019

A novel Schiff base has been derived from condensing 4‐aminoantipyrine with diazotized salicylaldehyde. The derived compound acted as a colorimetric sensor for hazardous aqueous anions like CN−, F−, and CH3COO− among a list of anions. The colorimetric changes were further verified through absorption titrations. The detection limits were of the order of 10−10 M, which makes the sensor significant. The interaction of the anions with the sensor was stoichiometrically 1:1 with good binding constants. The sensor turns out to be a specific turn‐on emission sensor for CN− even in competitive environments. The F− ion sensing ability was extended to the determination of F− in a commercial toothpaste with good results.
Design and synthesis of novel sugar‐based nitrogen‐containing heterocycles as potential anticancer agents under microwave in water

Published: September 2019

A series of novel glycosyl nitrogen‐containing heterocycles derivatives were designed and synthesized. With the help of microwave, the reaction was carried out in water rapidly and afforded the target compounds in good yields. The acid catalysts that were essential for this kind of reaction under traditional heating method were avoided through this strategy. Preliminary biological evaluation showed that most of the compounds could inhibit the growth of A549 cells, but the inhibition of HepG‐2 cells was relatively poor. Notably, compound 2i displayed the best potency with an IC50 value of 3.42 μM against A549 cell lines, which is comparable with the common anticarcinogen paclitaxel (5.12 μM). Molecular modeling studies suggested that 2i may bind to the ATP‐binding site of epidermal growth factor receptor (EGFR), indicating a rational design strategy. These results provide a starting point for designing glycosyl nitrogen‐containing heterocycles as the potential drugs in lung cancer therapy.
