Published: July 2021

Bu çalışmada, mürdümük (Lathyrus sativus L.) bitkisinin fide gelişimi üzerinde alkali stresinin etkileri incelenmiştir. Bitki materyali olarak iki adet yerel populasyon (1603 ve 4403) ile İptaş ve GAP Mavisi çeşitleri kullanılmıştır. Çalışmada alkali çözeltisi olarak sodyum karbonat (Na2CO3)’ın 5 farklı konsantrasyonu (0, 25, 50, 100 ve 150 mM) uygulanmıştır. Çalışma tesadüf bloklarında bölünmüş parseller deneme desenine göre 3 tekerrürlü olarak kurulmuştur. Çimlenme ve fide gelişim özellikleri saksı ortamında 25 °C sabit sıcaklık, 10 saat aydınlık-14 saat karanlık koşullarda ve % 70 nem içeren iklim odasında belirlenmiştir. Yetişme ortamı olarak bölgedeki tarım alanlarından alınan toprak kullanılmıştır. Denemede çimlenme hızı, çimlenme oranı, sürgün uzunluğu, kök uzunluğu, sürgün ve kök kuru ağırlıkları, ham protein ve ß-N-oxalyl-L- a, ßdiaminopropionic acid (ODAP) içeriği incelenmiştir. Sonuç olarak, alkali stresine karşı vermiş oldukları tepkiler bakımından genotipler arasında farklıklar olduğu belirlenmiştir. Alkali dozları kıyaslandığında ise, genotipler 50 mM alkali dozuna kadar olumlu cevap vermiş, 100 mM alkali dozu ile birlikte tüm özelliklerin olumsuz etkilendiği belirlenmiştir. Buna göre, çalışmada kullanılan tüm mürdümük genotipleri 50 mM alkali içeriğine sahip alanlarda yetişebileceğini göstermiştir.

Bu çalışmada, Alkanin/Şikonin (A/Ş) bakımından zengin olan Alkanna orientalis ve endemik Alkanna sieheana türlerinin tohum canlılığının test edilmesi, çimlenme yüzdesinin ve in vitro A/Ş üretimine uygun kallus rejenerasyonunun belirlenmesi amaçlanmıştır. Doğadan toplanan tohumların canlılık oranları tetrazolium yöntemi ile belirlenmiştir. Her iki türe ait tohumların çimlendirmeleri üç farklı (kurutma kâğıt arasında, agarlı MS besin ortamında, torf içerisinde) uygulama ile testi edilmiştir. Her iki türün tohumların kabukları çıkartılarak çeşitli oranlarda bitki büyüme düzenleyicileri içeren Murashige ve Skoog (MS) ortamında kültüre alınmıştır. Tohumların canlılık oranları A. orientalis için % 98.3 ve A. sieheana için ise % 96.0 olarak belirlenmiştir. Çimlenme oranları sadece filtre kağıdı arasında A. orientalis türü % 8.3 ve A. sieheana için % 5.0 olarak tespit edilmiş, diğer uygulamalarda çimlenme gözlenmemiştir. In vitro uygulamalarda, en yüksek zigotik sürgün ve kök oluşum oranı sırasıyla % 91.6 ve % 40.3 ile A. orientalis türünde gözlenmiştir. Fakat en yüksek kallus oluşum oranı ise % 75.0 ile A. sieheana türünde tespit edilmiştir. Sonuç olarak, her iki türünde canlılık oranlarının yüksek olmasına rağmen çimlenme oranlarının düşük, fakat in vitro üretilebilirliğinin ise mümkün olduğu tespit edilmiştir.
Professional Standard "Demograph" as a Factor of Formation of a New Human Resources Model
Authors: Rostovskaya Tamara , Zolotareva Olga
Published: July 2021

The article defines the prerequisites for the development of the professional standard “Demographer”, which is a fundamental stage for the formation of a new model of human resources in the field of demographic development. Content analysis of approved / valid documents revealed the absence of professional and educational standards for training specialists in the field of demography. Generalization and analysis of information on the subject area revealed existing problems, primarily in the field of public administration in the field of ensuring demographic security. The synthesis of modern methodological approaches made it possible to formulate the conclusion that demography as an independent type of activity (along with practical, scientific, etc.) has its own specialized (demographic) technologies and in modern conditions there is an urgent need to train professional personnel – “demographers”. Comparison of the All-Russian Classifier of Occupations (OKZ) with the International Standard Classification of Occupations 2008 (ISCO-08) and the International Standard Classification of Education (ISCED) and the emerging need for specialists-demographers were the basis for the implementation of the Institute for Demographic Research FCTAS RAS of an initiative project to develop a professional standard “Demographer”, which determines the conditions and opportunities for the development of education in the field of demography. The pool of developers makes it possible to formulate professional knowledge and skills (competencies) of both specific and interdisciplinary nature as much as possible, which determines the possibilities of work of demographers in various fields of science and practice. The professional standard “Demographer” will fully present and systematize uniform requirements for labor activity, as well as formulate requirements for graduates of professional educational organizations.
The purpose of the study is to develop a systematic approach to the formation of a new model of human resources in the field of demographic development. The development of the professional standard “Demograf” is considered to be the basic stage in the formation of a modern system of training highly qualified personnel. As a result of the adoption / approval of the professional standard “Demographer”, the possibilities of training specialists-demographers will be revealed both within the framework of the currently implemented areas of education, and in the future, to single out an independent direction of preparation of higher education “Demographer”, to develop educational standards for the bachelor’s and master’s degrees.

RISK OF RETURN CHARACTERISTICS OF ISLAMIC BANK FINANCING PORTFOLIO IN INDONESIA
Authors: Habibi Zamzam , Rusgianto Sulistya
Published: July 2021

The study aims to investigate the risk of return characteristics of Islamic bank financing portfolios. A quantitative approach of value at risk is used to estimate return volatility of Islamic commercial banks and Islamic business units in Indonesia for the period of May 2014 to June 2020. The finding suggests proportion of equity-based financing tends to increase in contrast to decreasing of debt and lease-based financing. While rate of return for all financing types tends to decline, the return of equity-based financing experiences higher volatility than other two financing types. The main finding regarding the decrease in value at risk indicates Islamic banks able to reduce risk of financing portfolio. The finding implies Islamic banks should continue to improve the best-practice of risk management based on their past experience to anticipate future risk. As for the regulators, the finding may be used to develop early warning system to anticipate a systemic failure in Islamic banking industry. Further research is recommended to explore impact of market behavior on the risk of each type of financing.
How Time is More than Money: The Mural as a Labour of Love
Authors: Kennedy Struan
Published: July 2021

This article proposes that of all the different ways that social connections are formed the most important factor is time. Given how central it is to the development of relationships, the article argues that projects aiming to improve community relations should extend their duration rather than truncate it for the sake of cost-efficiency or quick and apparent success. The project of specific focus is the making of community murals which is laden with potential but only when it is conceived in the entirety of the process rather than simply as an end product. This potential is based on the idea that more time, if used carefully and critically, can play a greater role in fostering positive relations in contexts where civic engagement is strained. Several case studies will be referenced from the United States of America and Northern Ireland, two societies that share both a tradition of mural making and social division, in terms of race relations and ethnonational/religious sectarianism respectively. Practical insights from these cases substantiate the central argument that the mural process affords moments for valuable cross-community contact, critical discussion, and meaningful reflection. When this approach is adopted, time can be best served in repairing social connections, creating new bonds and even mitigating further tension.

Published: July 2021

El presente artículo tiene por objetivo indagar la relación entre posición de clase y voto en el plebiscito por una nueva constitución en Chile. Para lo anterior, se tomaron los resultados de voto a nivel comunal publicados por el SERVEL y se asociaron estadísticamente, a partir del coeficiente de correlación de Pearson, con posiciones de clase considerando el esquema de “explotaciones múltiples” de Erik Olin Wright. Los resultados muestran una alta correlación positiva entre la opción Apruebo, la opción Convención Constitucional, y el proletariado; en tanto, esta relación se invierte, con una alta fuerza negativa, en el caso de la burguesía y los expertos directivos. Estos resultados sugieren una polarización en la defensa de los intereses de clase, a partir de la posibilidad de modificar el status quo consagrado por la actual constitución

A situação do saneamento básico brasileiro tem um contexto marcado por precariedades. Sanear essa realidade, primariamente, requer um bom planejamento estratégico. Seguindo as diretrizes nacionais, os municípios brasileiros são os responsáveis por formular suas respectivas políticas públicas de saneamento básico, ficando obrigados a elaborar seus Planos Municipais de Saneamento Básico (PMSBs). No Estado de Rondônia, atualmente dezenove municípios estão realizando a construção de seus PMSBs, contando com assessoramento técnico do Instituto Federal de Educação, Ciência e Tecnologia de Rondônia (IFRO), por meio do “Projeto Saber Viver” (Portaria nº 1876/REIT-CGAB/IFRO), uma cooperação entre a Fundação Nacional de Saúde (FUNASA) e o IFRO, por meio do Termo de Execução Descentralizada (TED) 08/2017. A participação e o controle social no processo de construção de políticas públicas é um fator determinante e um instrumento eficiente de transformação da realidade local. Nessa perspectiva, o presente artigo explicita a elaboração e aplicação das Estratégias Participativas referentes à Mobilização, Participação Social e Comunicação para a construção do PMSB nos municípios atendidos pelo Projeto, delineando as etapas e contextualização destas estratégias, bem como sua eficácia.

Quantum transport in zigzag graphene nanoribbon decorated with a phenanthrene molecule
Authors: Jiang Bo , Chen Qing-Yuan , Luo Jinlong , Zhao Yifen , Jin GuoJun , Yang Hai
Published: July 2021

By using the first principles calculations which combine density functional theory and nonequilibrium Green's function, we investigate the nanoscopic quantum transport of three hybrid structures consisting of a phenanthrene (PHE) molecule and a zigzag graphene nanoribbon (ZGNR). It is found that after decorated with the PHE molecule, the ZGNRs with the odd (even) zigzag carbon chains show the conductance reduction (enhancement), respectively. With the increase of the number of carbon chains, this odd-even difference will disappear. Moreover, negative differential resistance behavior can also be found in the hybrid structures consisting of the PHE molecule and the antisymmetric ZGNR. Finally, the differential conductance, transmission spectra, and molecular projection self-consistent Hamiltonian are used to explain the physical mechanism clearly. Accordingly, the proposed structures could have broad applications in the design of molecular nanodevices.

Authors: Fengyu Zhou , Yugang Wang
Published: July 2021

In this study, a closed-loop Dα -type iterative learning control(ILC) with a proportional D-type iterative learning updating law for the initial shift is applied to nonlinear conformable fractional system. First, the system with the initial shift is introduced. Then, fractional-order ILC (FOILC) frameworks that experience the initial shift problem for the path-tracking of nonlinear conformable fractional order systems are addressed. Moreover, the sufficient condition for the convergence of tracking errors is obtained in the time domain by introducing λ -norm and Hölder’s inequality. Lastly, numerical examples are provided to illustrate the effectiveness of the proposed methods.

Authors: Ostaszewska Agata , Domagala Piotr , Zawistowski Michał , Karpeta Edyta , Wszola Michal , Kosieradzki Maciej
Published: July 2021

Background: Infections in kidney transplant recipients are particularly challenging owing to the immunosuppressive treatment, usually long history of chronic illness, comorbidities and prior exposures to antibiotics. Among the most common complications early after surgery are surgical site infections. The aim of this study was to identify risk factors and evaluate epidemiological data regarding surgical site infections. Moreover, we were able to compare the current results with historical data from our institution when different perioperative antibiotic prophylaxis was practiced.Methods: We conducted a retrospective case-control study in a group of 254 deceased donor renal graft recipients transplanted in a single Central European institution. We evaluated epidemiological findings and resistance patterns of pathogens causing surgical site infections. We used multivariable logistic regression to determine risk factors for surgical site infections.Results: We revealed no differences in baseline characteristics between patients with and without surgical site infections. Ten surgical site infections (3.9%) were diagnosed (six superficial incisional, two deep incisional, and two organ/space). Eight species (19 strains) were identified, most of which were multi-drug resistant (63%). The most common was extended-spectrum β-lactamase producing Klebsiella pneumoniae (26%). We showed that statistically significant differences were present between reoperated and non-reoperated patients (adjusted odds ratio: 6.963, 95% confidence interval: 1.523-31.842, P = .012).Conclusions: Reoperation is an individual risk factor for surgical site infection after kidney transplantation. According to our experience, cefazolin-based prophylaxis can be safe and is associated with relatively low prevalence of surgical site infections.
Effect of Fungal Endophytes on Plant Growth and Nutrient Uptake in Trifolium Subterraneum and Poa Pratensis as Affected by Plant Host Specificity
Authors: García-Latorre Carlos , Rodrigo Sara , Santamaria Oscar
Published: July 2021

The introduction of well-adapted species, such as Trifolium subterraneum and Poa pratensis, might enhance the forage yield and quality of dehesas pastures for feeding livestock. However, the climatic hardness and poor soils in these agrosystems may limit plant establishment and development. Since fungal endophytes have been found to alleviate the environmental stresses of their host, the aim of this study was to assess the effect of five isolates on forage yield, nutritive value and plant mineral uptake after their inoculation in the two above-mentioned plant species. Two experiments were established (under greenhouse and field conditions) using plants inoculated with two isolates in 2012/2013 (Epicoccum nigrum, Sporormiella intermedia) and three isolates in 2013/2014 (Mucor hiemalis, Fusarium equiseti, Byssochlamys spectabilis). Thus, F. equiseti (E346) increased the herbage yield of T. subterraneum under greenhouse conditions, B. spectabilis was found to improve the forage quality of T. subterraneum by reducing fibre content and of P. pratensis by increasing crude protein. Also, S. intermedia increased the mineral uptake of Ca, Cu, Mn, Pb, Tl and Zn in subclover and M. hiemalis, the uptake of K and Sr in Kentucky bluegrass. These results evidenced the potential of the studied fungal endophytes to enhance herbage yield and the forage nutritional value, although further studies should include all of the intended forage species as certain host specificity in the effect was observed.
Kaposiform Hemangioendothelioma of the Sublingual Gland in an Adult: Resection is the Key.
Authors: Chowdhary Stuti , Sekar Raghul , Saxena Sunil Kumar , Badhe Bhawana
Published: July 2021

Introduction: Kaposiform haemangioendotheliomas (KHE) are extremely rare, borderline malignant, locally aggressive vascular tumours. Although more commonly seen in childhood and adolescents, some very rare reports in adults do exist. KHE is usually found in the retroperitoneum, over the extremities and the soft tissues of the trunk, mediastinum and the head and neck regions. Prior published reports have shown a strong association with the Kasabach-Merritt phenomenon (KMP). We present a very rare case of KHE of the sublingual gland in an adult, which was not associated with KMP and was resected completely without any sequelae. Case report: A 42-year-old female presented with a painful swelling over the floor of the mouth on the right for a year. Clinical examination revealed a bi-digitally palpable, non-transilluminant lesion on the right side of the lingual frenulum. Radiological investigations suggested the possibility of a benign soft tissue tumour arising from the sublingual gland. The patient underwent an intraoral excision of the lesion. The biopsy revealed spindle-shaped tumour cells in fascicles, surrounded by vascular spaces, suggestive of a KHE. The patient was offered radiation therapy, which she declined and continued to be on follow-up for two years. She remains symptom-free to date.Conclusion: Excision of a KHE of the floor of the mouth proved to be sufficient, without the evidence of any residual lesion or progression of symptoms. To the best of our knowledge, our case represents the first reported case in the literature of a KHE arising from the salivary glands in an adult.

Fusarium verticillioides is pathogenic to maize and mycotoxin-producer, causing yield losses, feed and food contamination, and risks to human and animal health. Endophytic (ISD04 and IPR45) and epiphytic (CT02 and IM14) bacteria from maize silks were tested in vitro and greenhouse against F. verticillioides and for hydrolytic enzyme production (cellulase, pectinase, protease, lipase, and chitinase). The strains were assigned as Achromobacter xylosoxidans (ISD04), Pseudomonas aeruginosa (IPR45), and Bacillus velezensis (CT02 and IM14) by 16S gene sequencing. All strains showed antifungal activity in vitro with inhibition values from 58.5–100%; they changed hyphae morphology and inhibited the conidial germination by up to 100% (IPR45). The four strains produced at least one enzyme with antifungal activity. The microbiolized seeds reduced the fungal development in stored grains and stalk rot severity in the greenhouse by 72.6% (ISD04). These results highlight the potential of these strains as biocontrol agents against F. verticillioides
Prognostic Nomogram for Death from Pneumocystis Pneumonia in Non-HIV- and HIV- Infected Patients
Authors: Feng Qiuyue , Hao Jingjing , Li Ang , Tong Zhaohui
Published: July 2021

Background: Pneumocystis pneumonia is a major cause of death in immunocompromised patients. Many risk factors for poor prognosis have been reported, but few studies have created predictive models with these variables to calculate the death rate accurately. This study created nomogram models for the precise prediction of mortality risk in non-human immunodeficiency virus (NHIV)- and human immunodeficiency virus (HIV)-infected patients with Pneumocystis jirovecii pneumonia (PJP).Methods: A retrospective study was performed over a 10-year period to evaluate the clinical characteristics and outcomes of NHIV-PJP at Beijing Chaoyang Hospital and HIV-PJP at Beijing Ditan Hospital in China from 2010 to 2019. Univariate and multivariate logistic regression analyses were used to screen out mortality risk factors to create the nomograms. Nomogram models were evaluated by using a bootstrapped concordance index, calibration plots and receiver operating characteristic (ROC) curves.Results: A total of 167 NHIV-PJP patients and 193 HIV-PJP patients were included in the study. Pneumothorax, febrile days after admission, CD4+ T cells ≤100/µl and sulfa combined with caspofungin (CAS) treatment were identified as independent risk factors for death that could be combined to accurately predict mortality risk in NHIV-PJP patients. We created a nomogram for mortality by using these variables. The area under the curve was 0.865 (95% confidence interval 0.799-0.931). The nomogram had a C-index of 0.865 and was well calibrated. The independent risk factors for death in HIV-PJP patients included in the nomogram were pneumothorax, platelet (PLT) ≤80×109/L, haemoglobin (HGB) ≤90 g/L, albumin (ALB), cytomegalovirus (CMV) coinfection and sulfa combined with CAS treatment. The nomogram showed good discrimination, with a C-index of 0.904 and excellent calibration. The area under the curve was 0.910 (95% confidence interval 0.850-0.970).Conclusions: Our nomograms were useful tools for the precise prediction of mortality in NHIV-PJP and HIV-PJP patients.

Published: July 2021

Following 22 additional months of post-operative follow-up and 6 further controls (total controls, n= 95) here the final results of a 2:1 control-case retrospective observational study are shown. Controls were ER+HER-2- metastatic breast cancer patients who were given first-line hormone therapy (HT) with aromatase inhibitors (AIs) or fulvestrant. Moreover 28 of them (28.9%) also received biological drugs including cyclin kinase inhibitors (CKis). Cases were 42 ER+ metastatic breast cancer patients who received the addition of interferon beta-interleukin-2 immunotherapy to first-line HT with selective estrogen receptor modulators/down-regulators (SERMs/SERDs). Median PFS and OS maintained significantly longer in the 42 studied patients who received hormone immunotherapy (HIT) than in the 95 controls (median time 33 vs 18 months, p=0.002 and 81 vs 62 months, p=0.019). In the analysis adjusted for disease-free interval (DFI), hormone receptor, HER-2 status, visceral involvement, AIs and biological therapy, the PFS and OS hazard ratio (HR) further increased in favor of the 42 cases (p = 0.004 and p = 0.044 respectively). In the same type of patients treated with AIs plus CKis a median PFS ranging from 25.3 to 28.18 months and a median OS of 37.5 months occurred. Overall, this strongly suggests multi-centre randomised clinical trials to enter our proposed immunotherapy into clinical practice.

Databases from the laboratory were analyzed and four groups were formed: people seeking HIV-1 voluntary counseling and testing (VCT), people in prison (PPr), people living with HIV (PLWH) and patients from primary care clinics (others). Syphilis diagnosis was made using the reverse algorithm; antibody titers were examined to determine the stage of infection. Baseline data was analyzed, and with follow-up information, a retrospective dynamic cohort was formed. Factors associated with seroprevalence of syphilis and active syphilis were evaluated by the chi-square test. Moreover, risk factors for the incidence of syphilis were described. Results. A total of 81,863 baseline individuals were analyzed. Syphilis seroprevalence was 9.9% in VCT, 8.2% in PPr, 37.0% in PLWH, and 8.7% in others; the prevalence of active syphilis was 1.7-13.1%. A total of 11,124 people were followed-up; the incidence (cases per 100 years people) was 3.5 among VCT and 16.0 among PLWH; moreover, the frequency of re-infections was 11.1-24.4%. Men, transgender, persons between 20-39 years old, and individuals with a history of HIV or hepatitis B had a higher risk of syphilis. Conclusions. Several vulnerable groups have exhibited a reemergence of syphilis, with high prevalence of active syphilis, high incidence, and re-infections. Persons living with HIV had the highest risk.

ObjectivesTo determine recommendations for the use of personal protective equipment (PPE) based on transmission risk for paediatric procedures in the Emergency Department during the COVID-19 pandemic. MethodsTwo survey rounds were conducted in April-May 2020. The survey presented a number of emergency medicine procedures relevant to the care of children, and asked respondents to provide PPE recommendations according to levels of community transmission, and whether or not the child had symptoms of acute respiratory illness. ResultsParticipants were recruited by approaching relevant professional groups, with 15 from the PREDICT network and 12 from the Australasian Society of Infectious Diseases (ASID) Paediatric Infectious Diseases (ANZPID) Group. Airborne PPE is recommended for resuscitative procedures and various respiratory procedures in most situations There were differences in opinion between emergency and paediatric infectious disease specialists with regards to most appropriate PPE for children without symptoms of COVID-19 in a setting of low community transmission, and for procedures involving the head, neck or airway. In general, emergency physicians were more likely to favour airborne PPE than infectious disease specialists. In the setting of high community transmission, there was a stronger tendency to recommend at least droplet precautions for most procedures – regardless of whether or not the child had symptoms. ConclusionsDifferences in PPE recommendations for various paediatric procedures between infectious disease specialists and emergency physicians were identified. Further research is urgently needed to clarify and quantify risks for many common interventions and determine strategies for multidisciplinary consensus regarding future recommendations.

Authors: RANGASWAMY ARJUN KETHUPURA , P Surekha T
Published: July 2021

The Major Setback of a Multi-Carrier Modulation (MCM) is Synchronization Errors, which includes time, frequency and phase offset. Especially, Wavelet based MCM catches the eyes of researchers due to its flexibilities which are seen as one of the strong contender for Cognitive Radios. Synchronization errors are mainly due to mobility between nodes and sub-optimal local oscillators and it is necessary to learn the behavior of wavelets under these channel fading conditions. In this paper, we present the joint effects of Wavelet-based Cognitive Radio OFDM (CR-WOFDM) systems under Synchronization Error in terms of based bit error rate (BER). BER Outputs of WOFDM is compared with FFT based OFDM with Cyclic Prefix (CP-OFDM) systems in a doubly-selective channel by designing a communication system for computer simulation. Several well-known wavelets are chosen and analyzed, including Daubechies (db), Symlets (sym), Coiflets (coif), Fejér-Korovkin (fk) filters, and biorthogonal (bior) wavelets. First, we show the behavior of wavelets in terms of BER by considering different doubly selective channel Power Delay Profile (PDP) like, AWGN, FLAT, Pedestrian and Vehicular and channel Doppler models like, Uniform and JAKES. Finally, we calculate and plot Signal-to-Interference Ratio (SIR) of WOFDM with Time and Frequency Offset and compared the results with FFT based CP-OFDM.

Published: July 2021

We first show a sufficient and necessary condition that a solution of fuzzy relation inequalities with addition-min composition is a minimal one. We then prove that for every solution of the fuzzy relation inequalities there exists a minimal solution that is less than or equal to the solution in a very different way. We finally give an algorithm to find a minimal solution for a given solution, which is illustrated by numerical examples.

The brinjal shoot and fruit borer, Leucinodes orbonalis is a destructive pest of Solanum melongena. The control of L. orbonalis with extensive application of synthetic chemical insecticides resulted in the development of resistance with known genetic heterogeneity among populations. Understanding the genetic diversity of their populations is important in developing strategies for their management. The present investigation was performed to characterize populations of L. orbonalis for their genetic diversity in the entire region of Tamil Nadu, South India using random amplified polymorphic DNA (RAPD) primers as a tool of the molecular marker. Among sixty random 10-mer primers, only ten primers generated reproducible and scorable banding profile. Among the ten different random primers, the primers namely OPG 7, OPG 8, OPS 2 and OPS 7 generated the highest genetic variation with over 80% genetic polymorphism. Phylogram analysis produced 18 clusters with 8 major and 10 minor clusters. Cluster analysis, statistical fitness, population structure and analysis of molecular variance confirmed the significant genetic variation among different populations. A trait specific marker obtained through RAPD was cloned, sequenced and used to develop a stable diagnostic SCAR marker for DNA fingerprinting to distinguish the populations. Amplification of this locus in the samples of 20 different populations indicated recognition of the trait for pesticide resistance in 12 populations. The results suggest that the biochemical nature of host plant varieties of this insect pest and variation in the application of different insecticides are essential contributing factors for the genotypic variations observed among populations of L. orbonalis.

Background: Great advance has been achieved in the investigation of Hippo signaling on mediating carcinogenesis. However, the underlying mechanism that YAP1/TEAD4 signaling regulated hepatocellular carcinoma (HCC) progression have not been completely determined. This investigation aimed to determine the mechanism of activation of YAP1/TEAD4 pathway and its regulatory effect on hepatocarcinogenesis.Methods: The TCGA database and immunohistochemical (IHC) analyses about HCC samples were carried out to analyze the expression of TEAD4 and its correlation with HCC prognosis. CCK-8, wound healing assay and transwell chamber with Matrigel were used to examine the role of TEAD4 on cell proliferation, migration and invasion capacities. In vivo imaging system was used to observe the tumor formation in SCID mouse model. The mechanistic investigation was conducted with functional studies, Western immunoblotting, Luciferase reporter assay, chromatin immunoprecipitation.Results: Analysis of HCC samples revealed that TEAD4 was up-regulated in HCC tissues compared to adjacent liver tissues, and its overexpression in HCC was significantly associated with worse prognosis, high serum AFP level, larger tumor size, PVTT, multiple tumor lesions, and microvascular invasion. Enforced expression of TEAD4 in HCC cell lines promoted the proliferation and growth of HCC cells in vitro and in vivo. The further functional studies showed that TEAD4 increased TWIST1 expression directly in the binding-promoter manner and then enhanced the migration and invasion of HCC cells via inducing epithelial-to-mesenchymal transition (EMT).TWIST1 was found to enhance E2R expression and consequently formed a positive feedback loop to activate the YAP1/TEAD4/TWIST1 axis.Conclusion: This investigation provided the functional and mechanistic basis for identifying the E2R/YAP1/TEAD4/TWIST axis as the oncogenic factor which inducing EMT and then accelerated HCC growth and invasion.

Background: This study aimed to evaluate the effects of child neglect and abuse training on the knowledge and awareness of medical vocational schoolteachers in Turkey. Methods: This study was conducted with teachers from Kayseri, Turkey, between October 2016 and April 2017. Teachers who agreed to participate in the study received training on child neglect and abuse. Data were collected through a survey form and by the Scale for Identifying the Symptoms and Risks of Child Abuse and Neglect. Data were analyzed through the software SPSS V.20.0. For statistical analyses, student’s t test, analysis of variance and McNemar tests were performed, with p< 0.05 value being considered statistically significant. Results: Of the teachers, 63.7% were female and 80.5% were married. Teachers’ mean age was 40.5 ± 9.9 years. Of the teachers, 87.4% reported the training was adequate. Teachers’ level of knowledge on neglect and abuse and the percentage of those who reported that they would report it to the authorities when faced with such a case increased after the training. Women teachers’ scores for the neglect and abuse scale increased among those without children and who found the training adequate. Conclusions: Teachers’ knowledge level in the study group prior to the training was found higher. The subject of child neglect and abuse should be further discussed during teachers’ formal training.
Demand for Cashew Nut Exports of Guinea-Bissau (1990-2011): VAR Model Application
Authors: Cateia Julio Vicente
Published: July 2021

This study aimed to estimate via VAR the reaction of the export demand for Guinea-Bissau Cashew nuts to the shocks of world income, exchange rate and of the foreign and domestic prices and of the effects of the Civil War, which occurred in the country from 1990 to 2011. The main results obtained by analyzing the impulse response function and variance decomposition, showed that changes in domestic price and exchange rates don’t explain the external demand for this commodity. External demand responds to changes in global income and foreign price. Moreover, the Civil War of 1998 influenced the foreign demand. In the long run, external demand for cashew nuts doesn’t react to shocks in any of the variables in the model.

The toe joint is one of the critical factors in designing a prosthetic foot. This is because its nonlinear stiffness provides a general feeling of springiness in the toe-off and it also affects the ankle kinetics. In this study, the toe part of the prosthetic foot was designed to improve walking performance. The toe joint was implemented as a single part suitable for 3D printing. The various shape factors such as curved shape, bending space, auxetic structure, and bending zone were applied to mimic human foot characteristics. The finite element analysis (FEA) was conducted to simulate terminal stance (from heel-off to toe-off) using the designed prosthetic foot. To find the structure with characteristics similar to the human foot, the optimization was performed based on the toe joint geometries. As a result, the optimized foot showed good agreement with human foot behavior in the toe torque-angle curve. Finally, the simulation conditions were validated by comparing with human walking data and it was confirmed that the designed prosthetic foot structure can implement the human foot function.
