Background:Studies indicate that Trichomonas tenax is a significant factor in the development of gingivitis and periodontitis in the gingival region. This organism is an opportunist that can thrive in the environment created by periodontal disease. Objectives:The aim of this study is to detect T. tenax using real-time quantitative polymerase chain reaction (RT-qPCR) technique in plaque-induced gingivitis (PIG) patients in Babylon. Materials and Methods:This study involved 50 healthy participants (control group) and 50 patients with PIG. Saliva samples were collected from each patient and transported to the Alharithia and Baghdad laboratories of the Advancement Scientific Office Learning Center for molecular testing. Results:T. tenax infection was identified using RT-qPCR and melting curve analysis in 16% of the gingivitis patients (PIG) exposed to plaque. Furthermore, a statistically significant correlation was observed between patient age groups and the presence of PIG disease, as indicated by the t test (27.568, P = 0.000), and between sex, as determined by the t test (8.573, P = 0.000). Conclusion:This study underscores the higher prevalence of T. tenax in patients with PIG disease. Furthermore, it highlights the correlation between these presence of these parasites and the age and sex of PIG disease patients.

The workforce is changing as new employees enter the labour pool. Malaysia’s largest demographic segment is currently Gen Z, constituting 38% of the total population, and boasting a monthly disposable income of US$428 million. Over the next ten years, up to 10 million people in Malaysia born after 1995 (i.e., Gen Z) will enter the workforce. The purpose of this research is to investigate the relationship between job security and employee retention through the mediating mechanism of affective organizational commitment and employees’ psychological empowerment among Gen Z, who are currently working and making up part of the workforce in Malaysia. Gen Z is characterized by distinctive attributes, demanding that human resource management (HRM) professionals anticipate potential innovations in their recruitment and training methodologies. Among the paramount concerns confronting HRM lies the challenge of employee retention, which holds a pivotal position in the overall success of an organization. This centrality is underscored by the financial burdens linked to the recruitment and training of fresh personnel, the disruption of business continuity occasioned by employee departures (commonly referred to as ‘turnover’), and the ensuing decline in productivity stemming from employee attrition. One strategy to increase retention is job security, because the finding of this research show that employees who have job security have high commitment and psychological empowerment, as well as high intention to stay in organizations. Implications for theory and research and management practice are discussed.

Anxiety is identified as a main issue that may highly lead to the feelings of nervousness, worry, tension, and apprehension. The purpose of the study is to measure the impact of the three components of writing anxiety (somatic, avoidance behavior, and cognitive) on Iraqi EFL learners’ attitudes and also attempts to determine the component causing the highest anxiety rates. Besides, the study also aims to detect the key elements that provoke anxiety. Two questionnaire tools, listed under the quantitative approach, were adopted in this study: The Second Language Writing Anxiety Inventory developed by Cheng and Causes of Writing Anxiety Inventory developed by Rezaei and Jafari. Hundred Iraqi undergraduate students, 50 males and 50 females, were assigned to take part in this study at “Al-Nisour University College.” The finding demonstrated that the participants are affected by all the three aforesaid components. However, the component “avoidance behavior anxiety” had a higher effect rate on the participants’ attitudes compared to the two components, dubbed “cognitive and somatic” that showed otherwise. Added to this, the findings also revealed a significant difference between genders wherein female learners showed a higher rate of anxiety than their male counterparts. This points out that female students may highly have an inclination to evade the situations demanding writing. Linguistic difficulties, fear of teacher’s negative comments, insufficient writing practice and self-confidence were respectively detected as the highest influential elements behind arousing anxiety. The current study highlighted the causes of writing anxiety and the effect of its components on Iraqi EFL learners and might contribute to paving the way to new teaching methods or techniques to mitigate the effect of these writing anxiety components and boost self-confidence in Iraqi EFL.

Online distance learning policies were formulated and implemented among some Malaysian universities long ago, but their value emerged since COVID-19. Emanating from the diffusion of innovation theory, this study examined the perception of higher education students on the influence and relationship between six independent variables (compatibility, observability, relative advantage, complexity, trialability, and digital skills) and one dependent variable (digital literacy). A total of 524 respondents were sampled, comprising students from six public and private Malaysian universities. The findings from the correlation analysis show a significant positive relationship between the six independent variables and the dependent variable. Meanwhile, in the regression analysis, three of the independent variables (observability, trialability, and digital skill) have a significant and positive effect on digital literacy. This study placed the diffusion of innovation in a specific context that supports designing online distance learning and digital literacy policies.

It is crucial to identify an efficient system for the sensing of formaldehyde (FD). The feasibility of utilising a B3S monolayer (B3SML) detector of FD was evaluated by analysing the adsorption, optical properties, gas-sensing behaviour, and electronic properties of FD and other gas molecules on the B3SML under density functional theory (DFT). The pristine B3SML was found to have satisfactory sensing toward FD molecules. The analysis of the adsorption mechanisms, geometric systems, adsorption energy, electronic and optical properties, charge transfer, and electron density differences revealed that the B3SML could potentially serve as an FD detector. It can be said that the B3SML is a promising sensor for detecting FD molecules. The present study contributes to the existing knowledge of gas-surface interactions and helps develop 2D sensor structures to detect FD gas molecules. [ABSTRACT FROM AUTHOR]

This article, published in the Arab Journal of Interventional Radiology, discusses the use of preoperative ultrasound-guided lateral abdominal wall botulinum toxin injection as a method to improve patient outcomes and reduce recurrence rates after ventral hernia repair. The injection of botulinum toxin type A (BTA) allows for fascial approximation and thinning of the abdominal wall musculature, which can reduce the need for additional surgical myofascial release. The article provides details on the injection procedure and dosage recommendations. It emphasizes the importance of radiologists being familiar with this procedure and the current literature.

Kant is known as the pioneer of artistic formalism. Art critics and commentators on Kant's works have also confirmed this claim. Kant discusses the form first in the critique of pure reason and then in the third moment of the critique of the power of judgment. According to Kant, what is universal in the judgment of the beauty and could be expected from all people is the form. Unlike the form, the sensory perception of an object varies depending on the perceptual ability of people. Roger Fry and Clive Bell, as formalist critics and artists, put forward Kant's concept of form in the 20th century, and by emphasizing it as the only act of beautifying works of art in the modern era, they played an irreplaceable role in the expansion and development of Kant's view on the concept of form in modern art. This article aims to investigate the relationship between this concept in the thought of formalists and in Kant's aesthetics. It was determined by the conducted investigations that, although formalists consider form to be a kind of temporal-spatial arrangement of the sensuous intuitive manifolds, in terms of their emphasis on the emotional expression of form in contrast to Kant's emphasis on the purposiveness without purpose of the form and the creation of the free harmony of imagination and understanding, there is a great difference between Kant's thought and Fry and Bell's formalist thought.

Objectives: This research aimed to investigate the impact of ozone on Leishmania major.Methods: Leishmania major promastigotes were exposed to ozone flow at varying concentrations (5, 10, 20, 30, and 40 ppm) for different durations (5, 10, 20, 30, and 40 minutes). The DNA of the treated promastigotes was extracted to evaluate DNA fragmentation. Apoptosis induction in the treated L. major promastigotes was analyzed using a specific kit. Additionally, scanning electron microscopy was employed to observe ultrastructural changes in the treated promastigotes.Results: The highest fatality rate (100%) occurred after 30 minutes of exposure to 40 ppm ozone gas, while the lowest fatality rate was 16.14% after 5 minutes of exposure to 5 ppm ozone gas. The DNA of the treated parasites was degraded, and significant morphological changes were observed in the body and flagella of the promastigotes. Induction of apoptosis was also noted.Conclusion: Ozone exhibits anti-Leishmania activity and induces apoptosis in Leishmania major. Furthermore, clear ultrastructural changes were observed in Leishmania major following ozone exposure. These findings suggest that ozone warrants further investigation as an anti-leishmanial agent.

Lead is a highly harmful environmental and occupational contaminant that works by inducing oxidative stress. Chelation therapy is the only treatment available in clinics for heavy metal poisoning, but it also has several adverse effects. This work assessed the in-vitro prevention effect of synthesized piroxicam derivatives for lead poisoning using the jobs techniques and NMR spectroscopy. Subsequently, in the presence of lead nitrate, the cytoprotection of piroxicam derivatives was assessed and compared with EDTA as an effective chelator. As a result, all synthesized compounds effectively chelated the lead ions. Furthermore, possibly due to the antioxidant activity of piroxicam derivatives, these compounds were even more effective in preventing cell death caused by lead poisoning than EDTA. The results showed that piroxicam derivatives are helpful in metal poisoning treatment due to their chelation ability and antioxidant activity.

Background: The older adult population is growing in many countries worldwide, consistent with the aging of the vast baby-boom cohort. Older men have high rates of suicide in their post-retirement years, necessitating research investigating mental health promotion and suicide prevention in the peri-retirementperiod. Methods: Secondary analyses were conducted of pre-group data from 83 participants in a study of Meaning- Centered Men's Groups (MCMG; Heisel et al, 2020), an upstream community-based psychological intervention group for men over 55 facing the transition to retirement. Eligible participants met with investigators in an academic health sciences centre and completed measures of retirement satisfaction (RS), suicide ideation, and positive (e.g., psychological well-being, perceived social support, and life satisfaction) and negative psychological factors (e.g., depression, hopelessness, loneliness, and anxiety) prior to the start of a 12-week course of MCMG. Associations were investigated among measures of retirement satisfaction and the positive and negative psychological factors. RS was predicted to be positively associated with the positive psychological variables, and negatively associated with the negative psychological variables. We specifically predicted that RS would be negatively associated with suicide ideation, and that this association would be mediated by depressive symptom severity. negative psychological factors in the expected direction. Retirement dissatisfaction was significantly associated with suicide ideation (Geriatric Suicide Ideation Scale or GSIS), and particularly so with items assessing a perceived Loss of Personal and Social Worth. The association between RS and suicide ideation was significantly mediated by depressive symptom severity (Geriatric Depression Scale). Conclusions: Retirement satisfaction is closely associated with self-reported mental health and well-being variables among middle-aged and older men facing the transition to retirement. Severe dissatisfaction with retirement may be a suicide risk indicator, necessitating investigation and potential intervention. These and other findings will be discussed in the context of the importance of meaningful engagement in one's post-employment years. Key Words: suicide ideation; retirement satisfaction; upstream interventions; meaning in life [ABSTRACT FROM AUTHOR]

The trend of population growth in the last three decades will cause extensive changes in the age structure of Iran's population. So that it can be one of the most important challenges of the country in the coming decades. This development will have different effects and consequences in the process of social, economic and political development. In this research, with the aim of dynamic analysis of the economic effects of the structural changes of the age groups (the age group of the workforce) of Iran's population in the coming decades until 1455, and then the role of women's labor force in the process of gross domestic product is studied and review puts. Therefore, this research aims to understand more about the structural changes of the population in four age groups (under 15 years, between 15 to 44 years, 45 to 64 years and over 65 years) in the past decades, the present and its future forecast; Using the global model "World3" modeling of dynamic systems to simulate the country's population trend from 1355 to 1455, with "Vensim" software, it has predicted the structural changes of the population. Forecasts show that based on the probable fertility rate of 1.6 (announcement of the researches of the Statistics Center), the growth trend of the entire country's population will be increasing until 1425, and the trend will decrease from this year onwards. Also, until 1455, the growth trend of the population in the age group below 15 years will be decreasing, and the growth trend in the age group of the workforce (between 15-44 years, 45-64 years) will increase until 1415, and from this year onwards, the trend will decrease. According to the forecast, the growth trend in the age group above 65 years will increase. The findings show that the demographic trend of working age will happen about 10 years earlier than the decreasing trend of the total population. Therefore, to compensate for the deficit of economically active labor and improve the production process and increase per capita; Considering the existing capacity in the country, increasing the employment of women will be one of the most effective solutions in this crisis. In the following, a dynamic economic model is presented using Solow's growth model. To show how the effects of changes in the labor force pattern will be on the growth process of gross domestic production. Then the operational scenarios related to increasing the employment of women in the growth of production and the growth and development of the country; Provided. Also, practical and operational suggestions have been presented regarding how to reduce the side effects of population structural changes and its negative effects on the growth of domestic production (GDP) by establishing women's employment in the country's economic cycle.

Various metal sulphides were selected for gamma and neutron shielding prediction by (Phy-X and NGCAL). The gamma parameters calculated by both software programs in the studied energy range were found to be identical, with differences (Δ% less than 1%) between both models. The Mass Attenuation Coefficient (MAC), Mean Free Path (MFP), Half Value Layer (HVL), Tenth Value Layer (TVL), and Effective Atomic Number (Zeff) were calculated. Ag2S was a superior neutron and photon attenuator because it contains two silver ions with the highest density, mean atomic number, and metal composition in addition to the lowest (S%) among all sulphides under evaluation. Additionally, the Ag2S monoclinic network is fabricated from (2Ag+) linked to one (S2-). Therefore, the presence of heavy packed ions in the unit cell resulted in more gamma attenuation. The Zeff variation with the energy range of 0.015–15 MeV may be associated with the density, mean atomic number, composition (%) or weight fraction, total atomic cross-section, crystal geometry and elemental packing of each molecule. It can be concluded that Ag2S was the superior attenuator between the sulphides under prediction, especially at higher energies. The Gamma Protection Efficiency (GPE, %) was also calculated for the gamma shielding subject based on the Linear Attenuation Coefficient (LAC) data presented in the Beer–Lamberts law: GPE% = (1-e^(-µx)) * 100, where the thickness was assumed. The GPE% increased with increasing thickness and decreased with increasing energy. Also, silver sulphide showed the highest GPE among the other tested materials. The GPE% of the thermal or fast neutrons was also calculated, where the increasing order was SnS, SnS2, ZnS, MoS2, As2S3, CuFeS2, FeS, CoS, and Ag2S for thermal neutrons and SnS2, SnS, MoS2, As2S3, ZnS, CuFeS2, FeS, Ag2S, and CoS for fast neutrons.

The imperative advancement of gamma-ray shielding materials is pivotal for ensuring radioactive and nuclear safety. In this study, our objective was to ascertain key gamma ray shielding parameters, including the mass attenuation coefficient (μm), effective atomic number (Zeff), half-value layer (HVL), effective electronic density (Neff), mean free path (MFP), and exposure buildup factor (EBF), for four oxyanion complexes (CaMoO4, PbCrO4, PbMoO4, or CaWO4). These calculations were performed using Phy-X software within the photon interaction range of 0.015-15 MeV. The investigated ternary chromate, tungstate, and molybdate complexes with the molecular formula ABO4, where A = Ca or Pb and B = Mo, Cr, or W, exhibited an exponential decrease in μm with increasing photon energy in the low-energy region. Lead molybdate demonstrated the highest μm followed by PbCrO4, CaWO4, and CaMoO4, correlating with their respective mean atomic numbers and densities. The mean free path values followed the order of PbMoO4, PbCrO4, CaWO4, and CaMoO4, indicating superior shielding properties due to effective medium-photon interactions. The HVL increased with rising photon energy, with the minimum HVL observed in the presence of lead, primarily attributed to the photoelectric effect. Zeff exhibited a decrease with diminishing mean atomic number and density, with PbMoO4 displaying the highest Zeff, signifying superior γ-ray shielding capability. The exposure buildup factor (EBF) highlighted the interference of photons by calcium compared to lead compounds. The controlled parameters at low and high energy exposures were attributed to the anion and cation properties of the ternary ABO4, respectively. Among the evaluated materials, PbMoO4 emerged as the most effective gamma shielding material in the context of nuclear safety.

Introduction: The study discusses the uneven impact of the COVID-19 pandemic across various demographic groups in the US, focusing on Boone County, Missouri. The aim is to identify any correlation between factors such as gender, age, ethnicity, and religious beliefs with COVID-19 infection rates over a span of 22 months (from March 15, 2020, to December 2, 2021). Methods: The research methodology involves time trend analysis graphs for each demographic group, benchmarked against significant events like vaccine launches, the introduction of the delta variant, vaccine boosters, and the arrival of the omicron variant. Results: Preliminary findings suggest that males and certain racial groups, including Black or African Americans and the “All-Other” category, exhibit higher COVID-19 positivity rates throughout these defined periods. The study also delves into unique patterns among demographic groups during various phases of the pandemic. Conclusion: Our results supported the hypothesis that males and minority races such as Black or African Americans and All-Other are more likely to have a higher COVID-19 positivity rate across our defined epochs.

Background and Objective: Healthy kidneys filter wastes of various molecular masses (up to 40-60 kDa). Traditional hemodialysis only removes low-molecular-weight molecules (500 Da), not middle-weight substances (>500 Da). Therefore, most of these compounds remain as expected uremic toxins. Therefore, this study aims to determine the association of Hepcidin and anemia with inflammatory markers in dialysis cases on high flux hemodialysis (HD) compared with hemodiafiltration (HDF). Methods: This cross-sectional study was conducted on 203 patients in the age range of 20-70 years old with end-stage kidney disease who were undergoing hemodialysis using high flux and hemodiafiltration methods. Venous blood samples were taken without anticoagulation and ferritin, CRP and hepcidin levels were analyzed and compared. Findings: This study involved 203 cases with end-stage renal disease, with 103 in the HD group and 100 in the HDF group. The mean age of the cases was 49.5±15.5 years. Among the patients in the HD group, 79.9% had hypertension, while only 23% of the patients in the HDF group had hypertension. Additionally, 35.9% of the cases in the HD group had diabetes mellitus (DM), while 75% of the cases in the HDF group had DM. There were significant differences between the mean number of white blood cells (8.27±7.95 vs. 6.20±4.14), CRP (13.88±17.45 vs. 6.48±10.40) and hepcidin (2981.47±2325.38 vs. 1010.45±1136.18) between the groups (p

Background: Soluble transferrin receptor (sTfR) is a useful marker in the differentiation of anemia. Clinical utility is limited by lack of standardization between measurement procedures and interpretative recommendations. Our objective was to evaluate the analytical performance of a research sTfR immunoturbidimetric assay (Alinity c, Abbott Diagnostics) and compare it to three established measurement procedures., Methods: Assay imprecision was assessed with 7 panels across the analytical measuring interval. 159 patient samples were measured across four instrument systems (Alinity c [Abbott Diagnostics], Tina-quant c502 [Roche Diagnostics], Quantex Biokit [Werfen], and ACCESS [Beckman Coulter]). Ferritin was also measured to calculate an sTfR/Log Ferritin ratio. Sera from 100 reference individuals were assayed for sTfR and ferritin (Alinity) for reference interval (RI) verification (sTfR) or establishment (sTfR index)., Results: Assay imprecision met defined goals. Method comparison between Alinity c and ACCESS sTfR assays showed good agreement (slope: 1.06, intercept: -0.12, r: 0.989). Comparisons across other assays demonstrated significant proportional bias with slopes ranging from 0.44 (Tina-quant c502, mean bias: -2.52 mg/L) to 1.24 (Quantex Biokit, mean bias: 0.60 mg/L). A proportional bias was observed between other instruments. While the sTfR RI was verified on the Alinity assay, agreement in interpretation (within vs outside RI) between Alinity and other platforms ranged from 74.2 to 80.5 %., Conclusion: We report the first characterization of the performance of a research sTfR immunoturbidimetric assay (Alinity c, Abbott Diagnostics). Our findings emphasize the lack of harmonization between measurement procedures and result interpretation for sTfR and sTfR index, necessitating standardization efforts and clinical studies., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: MB, SA and RS are employees of Abbott.
