Immunotherapeutic Peptide Vaccine Approaches to Glioma
Authors:   Rhenix Lifesciences, Hyderabad, India, Lin Feng , Datta Souvik ,   Rhenix Lifesciences, Hyderabad, India
Published: October 2021

Heretofore, there are no FDA-approved immunotherapeutics for malignant gliomas despite many novel therapies currently in different stages of clinical trials. Malignant gliomas are immunosuppressive tumors and are difficult for immune effector cells to infiltrate the tumor sites in the central nervous system. This inefficiency results in median survival of about only two years with a few long-term survivors. Recent clinical trials of vaccine-based immunotherapies against malignant gliomas have demonstrated encouraging results in enhancing progression-free survival and overall survival of patients. The vaccine-based treatments include peptide and heat-shock proteins, dendritic cell-based vaccines, as well as viral-based immunotherapy. In this review, we will focus on recent clinical trials of neoantigen peptide vaccines on gliomas, the delivery routes of such peptide vaccines, their adjuvants, clinical challenges, and its future strategies, respectively
The Effect of Investment, Exports, and Interest Rates on the Gross Domestic Product of the Republic Of Yemen: An Econometric Analysis
Authors: AL-Rafik Mohammed Y.
Published: October 2021

Purpose: The study aims to examine the effect of investment, exports, and interest rates on the gross domestic product of the Republic of Yemen.
Approach/Methodology/Design: This study is based on secondary data. Data on the gross domestic product, interest rate, gross capital formation were obtained and analyzed using the autoregressive distributed lag (ARDL) technique, Wald test, Serial Correlation LM Test. The data were presented the
Findings: The results through the use of the (E-VIEWS) program showed that there is a direct statistically significant relationship at a level of 5% between investment and gross domestic product. This means that if investment increases by 1%, it will lead to an increase in GDP by 28.63%. The result also showed that the dummy variable relationship to the GDP is direct and statistically significant. The level of significance is 5%, that is, by increasing the dummy variable by 1%, it leads to an increase in GDP by 25.13%. As long as the interest rate was on an inverse relationship and statistically significant at a significant level (10%), this means that an increase in interest rates by 1% would lead to a decrease in GDP rates by 19.54%. In addition, there is a positive relationship between exports and GDP and a statistical significance at level 5%. This means that an increase in exports by 1% leads to an increase in GDP by 69.76%.
Practical Implications: The investment could be double more than what the results showed in the case of political and economic stability. Improving legislation is also a significant aspect. There is an urgent need to focus on investment in infrastructure. In addition, increasing exports improve the gross domestic product. Based on the results, it is recommended to real invest instead of placing capital in banks as increasing interest rates lead to lower gross domestic output.
Originality/value: The analysis indicates that there is a direct statistical and significant relationship between total investment and gross domestic product at a significant level of 5%, as whenever the investment increased by 1%, this led to an increase in the gross domestic product by about 28.63%.
Viability of the Microencapsulation of Lactobacillus casei TISTR 390 Containing Inulin in Simulated Gastrointestinal Conditions and Storage
Authors: Nilsang Poonyanuch
Published: October 2021

This research aimed to determine the process condition for microencapsulation of Lactobacillus casei TISTR 390 by spray drying with maltodextrin and inulin as the coating agent. The physical properties and survivability of the microencapsulated cell were evaluated under simulated gastrointestinal conditions and during storage. Firstly, 3 inlet temperatures (150, 160 and 170 ºC) and 3 maltodextrin levels (5, 10 and 15 % (w/v)) were examined. The result reveals that an optimum condition was at 160 ºC inlet temperature with 15 % maltodextrin. Subsequently, inulin was added in 3 combinations; T1 (15 % maltodextrin and 5 % inulin (w/v)), T2 (10 % maltodextrin and 10 % inulin (w/v)) and T3 (5 % maltodextrin and 15 % inulin (w/v)) in an effort to generate synbiotic powder products. The best result was observed with a combination of 10 % maltodextrin and 10 % inulin. The obtained powder had a moisture content of 1.5±0.01 %, a water activity of 0.28±0.02, a total density of 0.71±0.04 g/mL, a solubility of 84.71±0.01 %, and a lactobacilli survival rate after spray drying of 90.76 %. The microencapsulated lactobacilli containing inulin powders were able to survive in acidic (pH 2) and bile salt solution (2 % w/v) after 120 min of incubation time with more than 60 % of the cell surviving. Furthermore, the microencapsulated powders were kept in aluminum-laminated bags at room temperature for 6 weeks and it was found that the cell viability remained at 6 log CFU/g. Therefore, a combination of an equal weight of maltodextrin and inulin was a promising protection agent for L. casei TISTR 390 in the simulated gastrointestinal conditions and during storage at ambient temperature.
HIGHLIGHTS

Microencapsulation probiotic bacteria with prebiotic by spray drying method contribute the synbiotic microcapsule
Microencapsulaiton with an equal weight of maltodextrin and inulin was promising as a protective agent to serve the survival in the gastrointestinal tract and during storage
The synbiotic microcapsule can survive at room temperature for up to 6 weeks in an aluminum-laminated bag.

La condición nutricional de un individuo influye en su desarrollo, pero la prevalencia de hábitos alimenticios poco saludables altera el equilibrio nutricional y desencadena varias complicaciones de salud y que también están influenciadas por los determinantes sociales de la salud. Por esta razón, este estudio tuvo como objetivo analizar los determinantes sociales de la salud y el estado nutricional de los estudiantes de una escuela primaria y secundaria pública en un barrio en las afueras de Belém, Estado de Pará, Brasil. Junto con la recopilación de medidas antropométricas, se utilizó un censo epidemiológico y alimentario, siguiendo protocolos ampliamente aceptados probados en la región amazónica, así como una evaluación clínica individual. Se realizó puntuación Z score y estadística descriptiva. Se midieron 55 estudiantes, 30 mujeres y 25 hombres, con una edad promedio de 13 años, un IMC promedio de 19.66 para el grupo femenino y 19.38 para el hombre, con un 4% de los niños con retraso severo, mientras que el 3.7% de Las niñas informaron un "retraso" en su crecimiento. El 13,3% de las niñas y el 25% de los niños beben alcohol. Los estudiantes mostraron un estado físico general sin complicaciones mayores, no hubo individuos obesos, pero existe un riesgo potencial para la afección. Sin embargo, debido a que es un área periférica, los determinantes sociales de la salud pueden fuertemente permitir el procesamiento de otras enfermedades nutricionales, como desnutrición y especialmente estrés, desde que identificamos un estudiante que se auto mutilan, y muchos otros que experimentan violencia diaria y baja esperanza de vida.

Published: October 2021

Este trabalho se direciona a buscar compreensões sobre quais recursos digitais estão sendo utilizados para a criação de objetos de aprendizagem para o ensino de Matemática e como isso tem acontecido. Trata-se de um mapeamento sistemático de teses e dissertações publicados no período de 2010 a 2019 na Plataforma Capes, seguindo as cinco etapas propostas por Petersen et al. (2008). Obteve-se um retorno de dezoito pesquisas e, a partir da sua leitura, apresentou-se uma relação dos recursos digitais indicados para a construção dos objetos de aprendizagem para o ensino de Matemática. Neste processo identificaram-se doze recursos, utilizados para explorar diferentes conteúdos matemáticos, tais como Funções e Geometria e, também, diferentes níveis de ensino, da Educação Básica ao Ensino Superior. Pôde-se perceber que o GeoGebra e o Scratch foram os recursos que tiveram maior destaque nestes trabalhos e que, para a quase totalidade dos autores, o uso dos objetos de aprendizagem exige novas posturas dos professores e abre novas perspectivas.
Parâmetros Curriculares Nacionais e Base Nacional Comum Curricular: uma comparação a partir da disciplina matemática
Authors: Geronimo Rafael Rix , Gatti Daniel Couto , Barbosa Lucas Diego Antunes
Published: October 2021

Esse artigo se propôs a comparar os Parâmetros Curriculares Nacionais e a Base Nacional Comum Curricular, observando a parte dedicada a disciplina de matemática, para responder às questões: o que foi atualizado entre um documento curricular e outro? Quais as diferenças e semelhanças entre os dois? Para tentar respondê-las realizamos uma pesquisa bibliográfica contextualizando a criação de documentos curriculares nos últimos 50 anos e realizamos uma comparação entre os dois documentos. Como resultados, percebemos que tanto a BNCC quanto os PCN foram documentos construídos sem a participação de professores e pesquisadores, sem considerar as contribuições que poderiam trazer para esses debates e de que a BNCC previu a criação de currículos estaduais e municipais complementando-a. Ainda assim, os PCN tinham a propósito de fornecer elementos para ampliar o debate dos professores, enquanto a BNCC e um outro de caráter normativo. Essa era uma necessidade que poderia trazer dificuldades na medida em que alguns estados e municípios podem ter dificuldades técnicas nessa elaboração. Nos pareceu ainda ter sido destacada a álgebra na BNCC, visto que se tornou uma unidade temática e o estudo de funções se tornou obrigatório no ensino fundamental.

Published: October 2021

В статье приведен обзор различных методов атак и подходов к атакам на системы искусственного интеллекта, построенных на основе искусственных нейронных сетей. Показано, что начиная с 2015 года исследователи в различных странах активно развивают методы атак и подходы к атакам на искусственные нейронные сети, при этом разработанные методы и подходы могут иметь критические последствия при эксплуатации систем искусственного интеллекта. Делается вывод о необходимости развития методологической и теоретической базы искусственных нейронных сетей и невозможности создания доверительных систем искусственного интеллекта в текущей парадигме.

The paper provides an overview of methods and approaches to attacks on neural network-based artificial intelligence systems. It is shown that since 2015, global researchers have been intensively developing methods and approaches for attacks on artificial neural networks, while the existing ones may have critical consequences for artificial intelligence systems operations. We come to the conclusion that theory and methodology for artificial neural networks is to be elaborated, since trusted artificial intelligence systems cannot be created in the framework of the current paradigm.

Fluorescent biological aerosol particles over the central Pacific Ocean: covariation with ocean surface biological activity indicators
Authors: Kawana Kaori , Matsumoto Kazuhiko , Taketani Fumikazu , Miyakawa Takuma , Kanaya Yugo
Published: October 2021

Abstract. Combining wideband integrated bioaerosol sensors and DNA-staining techniques, online and offline shipboard observations of
fluorescent aerosol particles in the atmosphere were carried out over the
central Pacific Ocean during March 2019 to identify bioaerosols and
determine their spatiotemporal distribution. To understand the origins of
and processes associated with bioaerosols, we conducted correlation analyses
of fluorescent particle number concentration, wind speed, and a variety of
chemical and biological indicators, including concentrations of chlorophyll
a, bacteria, and marine organic gel particles such as transparent exopolymer
particles (TEPs) and Coomassie stainable particles (CSPs). Five-day backward
trajectory analysis indicated that oceanic air masses were dominant between
6 and 18 March, after which the influence of long-range transport from the
continent of Asia was prominent. For the first period, we identified certain
types of fluorescent particles as bioaerosols with marine origins, because
their number concentrations were highly correlated with concentrations of
TEPs and bacteria (R: 0.80–0.92) after considering the wind speed effect.
For the second period, there was strong correlation between another type of
fluorescent particles and CSPs irrespective of wind speed, implying that the
fluorescent particles advected from land were mixed with those of marine
origins. From the results of our correlation analysis, we developed
equations to derive atmospheric bioaerosol number density in the marine
atmosphere over the central Pacific Ocean from a combination of biogenic
proxy quantities (chlorophyll a, TEPs, and bacteria) and wind speed. We
conclude that it is likely that TEPs were transported from the sea surface
to the atmosphere together with bacteria to form fluorescent bioaerosols.
First-principles modeling of the infrared spectrum of Fe- and Al-bearing lizardite
Authors: Balan Etienne , Fritsch Emmanuel , Radtke Guillaume , Paulatto Lorenzo , Juillot Farid , Baron Fabien , Petit Sabine
Published: October 2021

Abstract. The theoretical vibrational properties of a series of Fe- and Al-bearing
lizardite models have been determined at the density functional theory
level. Each periodic model displays a single cationic impurity substituted
at an octahedral or tetrahedral site of a supercell of lizardite
(Mg3Si2O5(OH)4) containing 162 atoms. The isovalent
Fe2+ for Mg2+ substitution has been considered, as well as the
heterovalent substitution of Fe3+ or Al3+ for Mg2+ or
Si4+. Comparison of the theoretical absorption spectra with previously
reported experimental spectra of natural and laboratory-grown lizardite
samples allows us to propose an interpretation for most of the observed bands.
Although the identification of specific bands related to octahedral
Fe2+ in FTIR spectra is challenging, broad bands at 3584 and 3566 cm−1 reflect the occurrence of octahedral Al3+ and Fe3+,
respectively, in the natural samples. These broad bands likely overlap with
potential contribution related to tetrahedral Al3+. It is suggested
that the modification of the H-bonding pattern related to the incorporation
of trivalent ions at tetrahedral sites has an overall broadening effect on
the interlayer-OH stretching bands of lizardite.
Impact of information presentation on interpretability of spatial hazard information: lessons from a study in avalanche safety
Authors: Fisher Kathryn C. , Haegeli Pascal , Mair Patrick
Published: October 2021

Abstract. Avalanche warning services publish avalanche condition reports, often called avalanche bulletins, to help backcountry recreationists make informed risk management choices regarding when and where to travel in avalanche terrain. To be successful, these bulletins must be interpreted and applied by users prior to entering avalanche terrain. However, few avalanche bulletin elements have been empirically tested for their efficacy in communicating hazard information. The objective of this study is to explicitly test the effectiveness of three different graphics representing the aspect and elevation of avalanche problems on users' ability to apply the information. To address this question, we conducted an online survey in the spring of 2020 that presented participants with one of three graphic renderings of avalanche problem information and asked them to rank a series of route options in order of their exposure to the described hazard. After the route ranking tasks, users were presented with all three graphics and asked to rate how effective they thought the graphics were. Our analysis data set included responses from 3056 backcountry recreationists with a variety of backgrounds and avalanche safety training levels. Using a series of generalized linear mixed effects models, our analysis shows that a graphic format that combines the aspect and elevation information for each avalanche problem is the most effective graphic for helping users understand the avalanche hazard conditions because it resulted in higher success in picking the correct exposure ranking, faster completion times, and was rated by users to be the most effective. These results are consistent with existing research on the impact of graphics on
cognitive load and can be applied by avalanche warning services to improve the communication of avalanche hazard to readers of their avalanche bulletins.
Rural and Urban Counties in Idaho: Differences in Vocational Rehabilitation Service Delivery and Outcomes
Authors: Grey Andrew
Published: October 2021

The Idaho Division of Vocational Rehabilitation (IDVR) sought to learn whether differences in VR service delivery and employment outcomes were present among consumers residing in urban and rural areas of the state. Case data for participants who had an Individualized Plan for Employment (IPE) signed and in place with the agency between 7/1/2017 and 6/30/2020 were examined to identify differences in employment outcomes and service delivery by county. A total of 7,235 cases were examined, 5,963 (82%) of which were residents of urban areas and 1,272 (18%) were from rural counties. Specific evaluation questions examined differences between these two groups regarding types of services provided to VR participants and length of time between initial IPE signature and service received. Analysis of administrative data indicated that training services were provided at a higher rate to participants in rural counties, whereas job search assistance, assessment, transportation, and maintenance services were provided at a higher rate to participants in urban counties. The overall successful case closure rate for urban (41.42%) and rural participants (41.80%) was comparable.
A Critical Examination of Cases Closed After Application for VR Services
Authors: Hollywood Kira
Published: October 2021

In the Texas Combined (Blind and General) Vocational Rehabilitation Services Division, 15% of cases were closed after an application was taken, but before eligibility was determined during the September 1, 2018 to August 31, 2019 time frame. This study was conducted to identify the primary reasons for these closures. Case services data and vocational rehabilitation (VR) counselor case notes were analyzed to determine if any substantive trends related to case closure after application were present and identify potential factors indicating a higher risk of case closure for those in application status. Further, the investigation found (a) errors in reporting codes by VR counselors, (b) individuals with intellectual and psychological disabilities being closed prematurely at higher rates than those with physical or other disabilities, and (c) a notable absence of communication from VR counselors informing applicants that their case was being closed. The findings from this study support the need for further assessment of why cases are closed after an application for VR services and indicate the need for VR staff training to clarify agency processes and participant engagement strategies to address and prevent premature closure of cases.
Evaluation of the South Carolina Vocational Rehabilitation Department (SCVRD) Information Technology Training Center
Authors: Chorey Jacob L.
Published: October 2021

This evaluation explored the effectiveness of the South Carolina Vocational Rehabilitation Department’s (SCVRD) Information Technology Training Center (ITTC) in regard to employment outcomes and cost per consumer served. It used a non-experimental design to quantitatively analyze existing program data for 55 consumers served during the 3-year period from July 1, 2015 to June 30, 2018 whose cases were closed by February 28, 2019, as well as a comparative sample of consumers served during the same time period by the agency’s general program. Outcomes for program participants were better than those of the comparative sample; however, the average cost expended per program participant was considerably higher. It is recommended the agency consider exploring more cost-efficient consumer IT training options via technical colleges and other training providers, rather than solely providing and delivering the training on-site.

Published: October 2021

Working-age adults with visual impairments have an employment rate of 43.5%, which was substantially lower than the employment rate (76.5%) of those without disabilities (Krause et al., 2018). However, research involving both youth and adults with visual impairments has identified positive associations between educational attainment level, specifically post-secondary education and training, and employment (Cmar et al., 2018; Lund & Cmar, 2019; Lund & Cmar, 2020). The Virginia Department for the Blind and Visually Impaired (DBVI) sought to better understand the consumer demographics and employment outcomes of individuals receiving post-secondary education as part of the vocational rehabilitation (VR) program. This study found that younger individuals who received college training services were more likely to achieve higher earnings. Policies on college training services for individuals with blindness and visual impairments are discussed.

Published: October 2021

Herbal medicine is gaining an increasing importance in the management of various ailments, but little is known about traditional practices in Algeria. This ethnopharmacological study aims to document medicinal and aromatic plants used in traditional medicine in the region of Tiaret (northwest of Algeria) in order to contribute to safeguard the local pharmacopoeia as cultural heritage, and to provide a scientific basis for developing novel strategies for such practices which can help for drugs discovery. Semi-structured interviews with 64 traditional healers and herbalists were realized in the region of Tiaret (Algeria) throughout field studies achieved from December 2018 to May 2020. Interviews covered sociodemographic information, popular and vernacular names of the medicinal plants, mode of use and toxicity among other data. Results reveal the use of 107 plant species belonging to 45 families and 97 genera for the treatment of various ailments. Lamiaceae, Apiaceae and Asteraceae were the most represented families.

В статье отмечается, что в Казахстане за последний период наблюдается снижение занятости населения при одновременном повышении уровня безработицы. Формирование новых реальностей в области занятости заставляет по-новому рассматривать расстановку сил между рынком и государством, работником и работодателем. В связи с этим актуализируется вопрос выбора инструментов социально- экономической политики, ориентированной на стимулирование занятости в Казахстане.
Проведен анализ основных индикаторов рынка труда Казахстана, рассмотрена структура наемных работников по статусу занятости за последние годы, удельный вес распределения занятого населения по видам экономической деятельности, уровень оплаты труда на предприятиях и организациях, занимающихся предпринимательской деятельностью.
Авторы отмечают, что основным направлением в области занятости населения является обеспечение внутренней и внешней конкурентоспособности малого и среднего бизнеса. Изучение динамики процесса региональных рынков труда, выявление основных причин незащищенной занятости и выявление существующих преград перехода на постоянную работу, усиление функций службы занятости должны стать основными задачами государственных органов занятости.
Для развития данной сферы государство должно продолжить создавать конкурентоспособную среду, распространение необходимых знаний, усиление работы профсоюзов и улучшение механизмов диалога с частным сектором.

The article notes that in Kazakhstan over the last period there has been a decrease in employment of the population, while the level of unemployment has increased. The formation of new realities in the field of employment forces us to consider in a new way the balance of power between the market and the state, the worker and the employer. In this regard, the issue of choosing instruments of socio-economic policy focused on stimulating employment in Kazakhstan is becoming topical. The analysis of the main indicators of the labor market in Kazakhstan is carried out, the structure of hired workers by the status of employment in recent years, the proportion of the distribution of the employed population by types of economic activity, the level of remuneration at enterprises and organizations engaged in entrepreneurial activity.
The authors note that the main direction in the field of employment is to ensure the internal and external competitiveness of small and medium-sized businesses. Studying the dynamics of the process of regional labor markets, identifying the main causes of insecure employment and identifying existing barriers to the transition to permanent work, strengthening the functions of the employment service should become the main tasks of state employment agencies. To develop this area, the state must continue to create a competitive environment, disseminate the necessary knowledge, strengthen the work of trade unions and improve mechanisms for dialogue with the private sector.
