A Lower Dose of Infection Generates a Better Long-Term Immune Response against Toxoplasma gondii
Authors: Moretto Magali M , Chen Jie , Meador Morgan , Phan Jasmine , Khan Imtiaz A
Published: March 2023

Toxoplasma gondii, an obligate intracellular pathogen, induces a strong immune response in the infected host. In the encephalitis model of infection, long-term protective immunity is mediated by CD8 T cells, with the CD4 T cell population providing important help. Most of the immune studies have used a 10- to 20-cyst dose of T. gondii, which leads to T cell dysfunctionality during the late phase of chronic infection and increases the chances of reactivation. In the current study, we compared the immune response of mice orally infected with either 2 or 10 cysts of T. gondii. During the acute phase, we demonstrate that the lower dose of infection generates a reduced number of CD4 and CD8 T cells, but the frequency of functional CD4 or CD8 T cells is similar in animals infected with two different doses. However, Ag-experienced T cells (both CD4 and CD8) are better maintained in lower dose–infected mice at 8 wk postinfection, with an increase number functional cells that exhibit lower multiple inhibitory receptor expression. In addition to better long-term T cell immunity, animals infected with a lower dose display reduced inflammation manifested by lesser Ag-specific T cell and cytokine responses during the very early stage of the acute infection. Our studies suggest a previously unappreciated role of dose-dependent early programming/imprinting of the long-term CD4/CD8 T cell response during T. gondii infection. These observations point to the need for an in-depth analysis of how early events shape long-term immunity against this pathogen.

The pleiotropic cytokine IL-9 signals to target cells by binding to a heterodimeric receptor consisting of the unique subunit IL-9R and the common subunit γ-chain shared by multiple cytokines of the γ-chain family. In the current study, we found that the expression of IL-9R was strikingly upregulated in mouse naive follicular B cells genetically deficient in TNFR-associated factor 3 (TRAF3), a critical regulator of B cell survival and function. The highly upregulated IL-9R on Traf3−/− follicular B cells conferred responsiveness to IL-9, including IgM production and STAT3 phosphorylation. Interestingly, IL-9 significantly enhanced class switch recombination to IgG1 induced by BCR crosslinking plus IL-4 in Traf3−/− B cells, which was not observed in littermate control B cells. We further demonstrated that blocking the JAK-STAT3 signaling pathway abrogated the enhancing effect of IL-9 on class switch recombination to IgG1 induced by BCR crosslinking plus IL-4 in Traf3−/− B cells. Our study thus revealed, to our knowledge, a novel pathway that TRAF3 suppresses B cell activation and Ig isotype switching by inhibiting IL-9R-JAK-STAT3 signaling. Taken together, our findings provide (to our knowledge) new insights into the TRAF3-IL-9R axis in B cell function and have significant implications for the understanding and treatment of a variety of human diseases involving aberrant B cell activation such as autoimmune disorders.

Published: March 2023

Yersinia enterocolitica represents one of the main foodborne pathogens in Europe and the evaluation of possible sources of contamination and its prevalence in food is of considerable interest for risk analysis approach. The results of the search for Yersinia enterocolitica in food samples taken in Umbria region (central Italy) were evaluated during the years 2015-2018. Different types of foods were considered, both ready-to-eat (meat products, dairy products, and raw vegetables) and meat preparations to be eaten after cooking. Samples were assayed by molecular screening for the species indicator gene ompF. Screening positives were subjected to isolation and characterization by searching for specific virulence marker genes, including the ail gene responsible for invasiveness and the ystB gene for the production of enterotoxin. The total prevalence of positive samples for Yersinia enterocolitica was 16.86% with a higher percentage of positive samples in meat preparations (19.35%), followed by ready-to-eat vegetables (11.76%). Poultry meat samples had a higher prevalence than pork and beef samples. Neither positive samples were found in meat products and dairy, nor seasonality in positivity was observed. All isolated strains of Yersinia enterocolitica were biotype 1A, with absence of the ail virulence gene but presence of ystB gene. Since the strains isolated from human patients appear to be primarily biotypes that possess the ail marker, future investigations would be needed regarding the real role of biotype 1A in human disease. In this context, attention should certainly be paid to ready-to-eat vegetables and to careful cooking of meat preparations.

Published: March 2023

The Commission Regulation (EU) No. 2021/382 (European Commission, 2021), amending the Regulation (EC) No. 852/2004 (European Commission, 2004), introduced the obligation for companies to establish and maintain a food safety culture (FSC). The methodology to evaluate, implement, and enhance the level of FSC is up to the individual companies. This study aimed to investigate the perception of FSC among the employees of 3 Tuscan medium-sized enterprises in the food sector, producing cured meat (A), dairy products (B), and frozen fish products (C). The survey was conducted through the development and administration of a questionnaire based on a 5 points Likert scale, referring to different aspects of FSC, organized in 6 sections with 5-6 statements each and subjected to a percentage of employees between 76 and 85%, classified also by the length of service (≤3 and >3 years). For all the companies, the minimum median and mode value for scores obtained by the different sections was 4, and the minimum median and mode value for the single statement was 3 (A, B; except for a bimodal value 2-4) and 4 (C). The section awareness and perception of risk showed the highest mean scores in all companies. As for the length of service, senior employees gave lower scores than junior ones in all sections in B and 3 sections in C. Overall, the results of the questionnaires showed a good perception of FSC, even though it was possible to identify some partial weaknesses.
The association between anemia and hypovitaminosis D
Authors: Alharbi Raed A.
Published: March 2023

Background

Hypovitaminosis D (deficiency and insufficiency) and anemia are both known as major public health concerns globally. A suboptimal level of vitamin D has been suggested to be a potential trigger player for reduced hemoglobin levels, thus increasing the risk of anemia.

Objective

The purpose of this study was to determine the prevalence of hypovitaminosis D and anemia, as well as the relationship between the two.

Patients and methods

Demographic and laboratory data were collected and analyzed (Pearson's correlation and multivariate logistic regressions) using IBM Statistical Package for SPSS, and graphical data visualization was performed using the R programming language and R-based Rstudio.

Results

The overall prevalence of vitamin D deficiency was 75% (n=302), whereas insufficiency and sufficiency were 19.7 and 4.5%, respectively. Vitamin D deficiency was most prevalent in the 30–49-year age group (n=155, 81%), whereas it was least prevalent in the 50–69-year age group (n=63, 65%). A significant positive Pearson's correlation was found between vitamin D concentration and hemoglobin at the 0.05 level (r=0.133 and P=0.05) and between vitamin D concentration and the patient's age in years at the 0.01 level (r=0.157 and P=0.01). Anemia was found to be prevalent in 36% of the population. Normocytic anemia was the most prevalent type, followed by microcytic anemia.

Conclusion

The role of hypovitaminosis D as a risk factor for anemia is unknown, and thus multiple longitudinal and interventional studies are recommended to establish an association between vitamin D deficiency and anemia.

Authors: Kim Haram , Hwang Sung Ha , Eom Youngsub , Nam Dong Heun
Published: March 2023

Purpose:

The aim of this study was to evaluate the efficacy of the illuminated chopper-assisted cataract surgery in terms of shortening the surgical time and reducing the use of pupil expansion devices in eyes with iris challenges.

Methods:

This was a retrospective case series of a university hospital. Four hundred forty-three eyes of 433 consecutive patients who underwent illuminated chopper-assisted cataract surgery were included in this study. Cases with preoperative or intraoperative miosis, iris prolapse, and intraoperative floppy iris syndrome were included in the iris challenge group. Use of tamsulosin, iris hooks, pupil size, surgical time, and improved visibility (100/surgical time × pupil size) were compared between eyes with and without iris challenges. Mann–Whitney U test, Pearson’s Chi-square test, and Fisher’s exact test were used for statistical analysis.

Results:

Of 443 eyes, 66 were included in the iris challenge group (14.9%). Tamsulosin use was more common in patients with iris challenges and iris hooks were used more frequently (9.1% vs. 0%, P < 0.001) in patients with iris challenges than in those without iris challenges. Pupil size was smaller in patients with iris challenges (6.01 vs. 7.64 mm, P < 0.001). However, surgical time was not different (16.9 vs. 16.5 min, P = 0.064) between the two groups. As a result, improved visibility was calculated to be higher in patients with iris challenges (1.05 vs. 0.81, P < 0.001).

Conclusion:

In terms of surgical time and improved visibility, using the illuminated chopper simplified cataract surgery involving iris challenges. The use of an illuminated chopper is expected to be a good solution for challenging cataract surgeries.

Academic Agency: The Impact of Underlying Dispositions that Affect Teachers' Sense of Responsibility to Educate all Children in a Middle Grades Mathematics Classroom
Authors: Poling Lisa Lanette
Published: March 2023

Based on the novel framework of Academic Agency, this study explored how a teacher's sense of efficacy, commitment, and knowledge influenced their overall sense of responsibility in instructing all children in the science of mathematics. This study employed a two-phase data collection process in which surveys, classroom interviews, and observations were used to examine practicing teacher's beliefs regarding efficacy, commitment, content knowledge, and responsibility. Pearson Correlation and Multiple Linear Regression were employed as analysis tools to identify the direction and strength of the relationships existing between variables. Findings suggest that there is a positive correlation between a teacher's sense of efficacy and their overall sense of responsibility and also a teacher's sense of efficacy and of mathematics teaching efficacy. The second phase of the study, participant interviews, and observations provided a more detailed look at how four purposefully selected educators enacted their articulated beliefs. Hour-long semi-structured interviews were conducted along with classroom observation. The qualitative data collected from the four individuals were analyzed using NVivo software. Based on recorded coding structures, individuals were placed into four predetermined categories ranging from Custodial Emphasis to Focused Academic Agent. Findings suggest that a sense of responsibility may be a factor in educational decisions.

ABSTRACT. The solubility of low-grade zinc ores with a selective leaching environmentally friendly reagent has become a focus of great interest since zinc and its compounds have found wide application. For this purpose, lactic acid was used to investigate the selective leaching kinetics of smithsonite ore obtained from Kayseri region. The effects of particle size (137.5-725 µm), acid concentration (0.5-5 M), solid/liquid ratio (0.5/250-3/250 g mL-1), stirring speed (500-800 rpm) and temperature (40-70 °C) parameters on the smithsonite dissolution rate were experimentally studied. The results obtained show that leaching of about 99.8% of zinc is achieved using 425 µm particle size at a reaction temperature of 70 °C for 45 min reaction time with 2 M lactic acid, the solid/liquid ratio of 1/250 g mL-1 and stirring speed of 600 rpm. The statistical analysis of the experimental data obtained from the parameters revealed that smithsonite dissolution was the surface reaction-controlled with an apparent activation energy of 53.62 kJ.moL-1. The kinetic model describing the process was found as

The study was conducted to determine constraints to the production and post-harvest handlings of selected neglected food crops (Bambara nuts, Bread  fruits and Bush mango) in South-east and South-south Nigeria. Production and post-harvest handling challenges have made some of the indigenous  crops that are capable of improving food security in the nation to be neglected and underutilized by the farmers. The specific objectives of the study were  to; ascertain the socio-economic characteristics of farmers of selected neglected food crops in the study area; determine the constraints militating  against production of selected neglected crops; identify the challenges encounter during post- harvest handling of the selected neglected food crops and  identify areas of research needs along production and post-harvest handling value chain of the neglected food crops in the study area. Purposive  and snow-ball sampling procedure were used to sample 120 farmers of selected neglected crops in southeast and South-South Nigeria. A well-structured  questionnaire was used to obtain information from the respondents and analyzed using percentage and mean. The results revealed that the mean age of  the respondents in the study area was 43.3 years, majority (42.5%) of the farmers attended primary school. The mean for years of farmer’s farming  experience was 13.3years.The production constraints to farmers in the study area were lack of financial support (3.8), lack of improved cultural varieties  (3.6),ignorance of the crop nutritional value (3.4) and susceptibility to pests and diseases (3.1) while the constraints to farmers during drying were, rain  (75.8%), Animal (29.2%) and dust (75.8%). Majority of the farmers (68.3%) mentioned mold growth on stored crops as a major storage challenge All the  farmers (100%) mentioned storage problem as area of research needs, while majority of the farmers (95%) suggested improvement on post-harvest  handling on neglected crops in the study area., simple and effective storage and processing innovation should be developed by research institutes and  made available in the study area.

Published: March 2023

ABSTRACTSince the discourse on religious censorship was presented by minister lukman (2014-2019) judge saifuddin (2014-2019), the ministry of religions has continued to develop knowledge and strengthen religious censorship narratives through various platforms in the digital world. The study focuses on increased religious censorship by the ministry of the republic of Indonesia on youtube, the most popular social media platform for today's Internet users. Using a method of analysis of content with a descriptive analysis method, the study reaches several conclusions. First, in intensity, the use of the youtube channel in strengthening religious censorship issues still needs to be increased. Of the total of 318 videos uploaded to the youtube account by the ministry of religion, only 15 (4.71%) contain content on censorship and religious harmony. The annual frequency was still low, and even in 2019 there was no content on moderation and religious harmony. Second, the concept of religious censorship is still applied primarily to intellectuals who have not touched millennials. Its trend is still limited in eradicating negative issues related to the government's religious regulation program. Third, according to the warganet reaction data on censored and harmonized video content remains low. It has been found that netizens prefer the term of harmony to moderation. This suggests that the people of Indonesia in general prefer harmony, but there are still some interpretations or negative impressions of the term "moderation" carried by the ministry of religions.Keywords: religious moderation, ministry of religion, youtube

ELEMENTARY PARTICLES, ATOMIC NUCLEI AND MOLECULES ACCORDING TO THE BSM – SUPERGRAVITATION UNIFIED THEORY
Authors:   YORK UNIVERSITY, TORONTO, CANADA, Sargoytchev Stoyan
Published: March 2023

The Basic Structures of Matter – Supergravitation Unified Theory (BSM-SG) is based on alternative concept of the physical vacuum. At small distance below 1 angstrom the Supergravitational forces appear as strong nuclear forces, while at larger distance they converge to the Newtonian gravity. Amongst the major outcomes from BSM-SG theory are derived material structures of the stable elementary particles forming the material structure of atomic nuclei. The protons and neutrons are not spherical but having a shape of twisted and folded torus, respectively. They are thin but with much larger size than the size of the atomic nuclei according to the QM models, so the Coulomb field is not converged to a size in the order of 10E-15 m but is distributed over much larger size of the proton. The BSM-SG models of nuclear structures exhibit an excellent match to the pattern of Periodic Table, showing signatures of valences, Pauli Exclusion Principle and Hunds rule. They also define the angular restrictions of the chemical bonds.

Published: March 2023

During the production and assessment of high-quality research, it is important to be open about how that research was produced and what can be concluded from it. The FSA set out to develop a ‘good science’ Quality Assurance Toolkit (QAT) to support its members to produce, assess and procure high-quality research. The FSA QAT was developed between February and August 2022 through a process of co-creation. A series of focus groups were held with FSA staff in March 2022. This was followed by a scoping review of internal and external guidance to help populate the QAT. The QAT was iteratively developed through multiple rounds of feedback from the FSA Advisory Committee for Social Science and was piloted on several study protocols, research reports, and tender specifications. The resulting QAT is intended to be easy to use whilst also supporting transparency in how scientific evidence is produced, assessed, and procured, to ensure that quality assurance is consistently applied across research projects and FSA staff.

Published: March 2023

Melon is attacked by pests such as the whitefly, Bemisia tabaci (Gennadius), the cotton aphid, Aphis gossypii Glover, the flower thrips, Frankliniella occidentalis (Pergande) as well as Diaphania worms that can affect yield and crop productivity. To control it, frequent spraying of organo-synthetic insecticides is carried out, which can generate ecological imbalances. During two productive cycles, experimental plots were established to test the effect of an organo-synthetic insecticide and a botanical one on some pests, a natural enemy and on melon productivity. The treatments tested were, 1. Organo-synthetic insecticide: lambda-cyhalothrin + thiamethoxam. 2. Botanical insecticide: azadirachtin. 3. Untreated plot. The populations of A. gossypii, B. tabaci, F. occidentalis, percentage of fruits damaged by Diaphania spp. (% FDD), and the effect on parasitism in B. tabaci (% PBT), as well as on yield (t.ha-1) and crop productivity. The populations of A. gossypii, B. tabaci, F. occidentalis, fruits damaged by Diaphania spp. (% FDD), and the effect on parasitism in B. tabaci (% PBT), as well as on crop yield and productivity. The % FDD, the populations of A. gossypii and F. occidentalis did not show differences between treatments. The yields were higher in plots treated with azadirachtin, where there were lower populations of B. tabaci and higher % PBT. Productivity presented a negative correlation with the populations of B. tabaci. Despite the control exerted by azadirachtin on B. tabaci, there was a decrease in productivity, which added to the damage of Diaphania spp. suggest the importance of these pests and for their management other alternatives should be tested that reduce populations to levels that do not affect yield and at the same time guarantee sustainable production.

Genler, canlılardaki görünüş, davranış, kişilik gibi özellikleri belirleyen ve bu canlılarla ilgili bilgi edinmek üzere kullanılan birimler olması ile birlikte canlıya ait bir özelliği denetleyen kromozom parçası olarak tanımlanmaktadırlar. İlk kez bir mühendis ve biyolog olan Holland tarafından 1975 yılında kullanılan genetik algoritma (GA), canlılardaki genetik kod mantığı aracılığı ile karmaşık problemleri hızlı ve kolay bir biçimde en iyi çözüme ulaştırmayı hedeflemektedir. Genetik algoritmalar, bir çözüm uzayındaki her noktayı, kromozom olarak adlandırılan ikili bit dizisi şeklinde kodlamaktadır. Bu noktaların her birine ait bir uygunluk değeri vardır. Dolayısıyla, tek bir nokta yerine noktalar kümesini muhafaza etmektedir. Genetik algoritmalar, çözümlerin kodlanması, uygunlukların hesaplanması, seçim, çaprazlama ve mutasyon operatörlerinin uygulanması adımlarını içermekte olup bu operatörlerden faydalanarak yeni bir popülasyon oluşturmaktadır. Bu derleme makalesinde genetik çalışmalarda çözümü oldukça zor olan problemlerin çözümünü kolaylaştırmak ve kısa zamanda mümkün olan en iyi çözümü ortaya çıkarmak adına geliştirilmiş olan genetik algoritmaların işleyişi ve uygulamalarında kullanılan operatörler ele alınmıştır.

Community outreach serves as a core function of higher education institutions which helps promote sustainable development goals worldwide. In the Philippines, universities have been mandated to provide extension activities and reach the most vulnerable communities in the country. Thus, the study used descriptive, comparative, and correlational approaches to determine the level of awareness, the extent of involvement, the degree of motivation, and the challenges in community outreach in a Catholic Higher Education Institution in the areas of spiritual-moral, education, sociocultural, health, economic, and environment. Using stratified random sampling, 459 students, faculty, and administrators participated in the study through a modified-standardized instrument. Mean, standard deviation, frequency, percentage distribution, Kruskal Wallis, and Spearman rank were used to analyze the data. The findings of the study unveiled that the respondents of the university have a very high level of awareness, a moderate extent of involvement, and a very high degree of motivation. The topmost challenge is time constraints. This signifies that members of the academic units are generally very aware of and highly motivated in community outreach, but involvement has yet to be enhanced. Findings suggest revisiting the community outreach plan and enriching its strategies to attain a more inclusive and progressive involvement among university stakeholders.

Authors: Joshua Orji
Published: March 2023

Purpose: This study assessed the effect of processing method on the carotenoid profile of oil from three varieties of the Nigerian oil palm fruits (elaise guinensis). Specific varieties of the elaise guinensis, which are the dura, pesifera and tenera were obtained from National Institute for oil palm research (NIFOR) in Edo state.

Methodology: The samples were divided into two and processed in two different methods as commonly practiced in the East, the hot and cold processes.  The oil extracted from each of the process was then analyzed for oil characteristics using standard analytical methods while the carotenoid profile was analyze using HPLC C21 column. The results generated were subjected to one-way analysis of variance (ANOVA).

Findings: The results of carotenoid constituent indentified include: lutein, neurosporene (trans), neurosporene (cis), α-Zeacarotene(cis), α-Zeacarotene(trans), phytoene, phytofluene, β-zeacarotene, 13 and 13’ cis α-carotene, 13 cis β-carotene, trans α-carotene, 9 cis α-carotene, trans β-carotene, αcarotene a(cis), α-carotene b(cis), α-carotene (trans), γ-carotene (trans),  γ-carotene b(cis), lycopene (cis) and lycopene (trans). The results of physicochemical characteristics of the oil samples extracted range from 0.9220.004 - 0.9160.001 for specific gravity (SG), 8.100.17 - 4.880.04 mg KOH/g for acid value, 4.290.02 - 2.440.02 % for free fatty acid value (FFA), 6.000.21 to 204.670.98 mgKOH/g for saponification value and 9.530.23 - 5.250.33 mEq/kg; for peroxide value while the carotenoids values were between 53.735±0.10 and 123.389± 0.20 mg/100g.

Unique Contribution to Theory, Practice and Policy: From the result we can observe that the main constituent of the palm oil carotenoid is the β -carotene which makes up to about 80% of the total carotene. Statistical analysis revealed that no significant difference exists between the mean of each of the processing method on the carotenoid profile of the oil sample analyzed.

The Role of Humanitarian Aid in Conflict
Authors: Muriuki Charity
Published: March 2023

Purpose: The term ‘humanitarian aid’ has outgrown its traditional Red Cross definition of ‘providing swift emergency assistance to people in disaster or emergency situations’. Today humanitarian action is commonly defined in a broader sense. The study sought to establish the role of humanitarian aid in conflict.
Methodology: The research was purely qualitative. Desktop literature review was conducted. Critical analysis of the literature was conducted.
Findings: The study found out that it is important to reiterate that humanitarian aid is not neutral in the midst of conflict. Aid and how it is administered can cause harm or can strengthen peace capacities in the midst of conflicted communities. All aid programmes involve the transfer of resources (food, shelter, water, health care, training, etc.) into a resource-scarce environment. Where people are in conflict, these resources represent power and wealth and they become an element of the conflict. Some people attempt to control and use aid resources to support their side of the conflict and to weaken the other side. If they are successful or if aid staff fails to recognise the impact of their programming decisions, aid can cause harm.
Unique Contributions to Theory, Practice and Policy: The study advocates for the use of conflict sensitive planning and programming in humanitarian intervention. In addition, it is recommended that coordination of efforts is by far a very important aspect that needs to be put into consideration in order to maximize the impact of humanitarian assistance. The researcher further recommends the use of Anderson DNH frame work, whose primary purpose of the DNH framework is micro conflict analysis, project planning and programme quality, and impact assessment of programme on conflict.
