Objective: The purpose of this study was to evaluate the immunohistochemical effect of hyaluronic acid (HA) on the mineralization rate of the reparative dentin when it is used as a mixing medium with mineral trioxide aggregate (MTA). Materials and Methods: Direct pulp capping (DPC) was performed on 90 teeth from 10 dogs that had been experimentally exposed. The exposed pulps were divided into three groups according to the mixing medium with MTA: Group I: MTA + distilled water (control group), Group II: MTA + hybrid cooperative complex HA (HCC-HA), Group III: MTA + high molecular weight HA (HMW-HA). After pulp capping, all cavities were restored with final restoration. The dogs were divided randomly into five groups (two dogs each) according to the evaluation periods (7, 14, 21, 30, and 60) days. At the end of the study, the dogs were euthanized, and the sampled teeth were processed for immunohistochemical investigation. Results: Both types of HA (HCC-HA, HMW-HA) showed an increase in the expression of alkaline phosphatase (ALP) at a higher rate than using distilled water with MTA. Conclusions: Within the limitations of this study, HA proved to be an effective additive to MTA for DPC. [ABSTRACT FROM AUTHOR]

Aims: To compare and evaluate marginal and internal adaptation and to assess the degree of conversion of alkasite restoration in relation with other restorative materials. Methods: on the buccal surface of 25 maxillary premolars a class V cavities were prepared. The teeth were randomly divided into five groups (n=5) that restored as: Group 1: alkasite without adhesive, Group 2: alkasite with adhesive, Group 3: Nanohybrid composite, Group 4: Glass ionomer cement, and Group 5: Resin modified glass ionomer cement. The teeth underwent 5000 cycles of thermocycling between 5° and 55°. Then, silver nitrate solution was infiltrated and Micro-Computed tomography analysis was performed using (LOTUS inVivo). For evaluating degree of conversion, 15 specimens in the form of a disc were prepared from Alkasite, nanohybrid composite and resin modified glass ionomer (n=5). All samples were analyzed using (FTIR) in an ATR Mode in three intervals (after 20 second. 24 hours and 7 days). The data had been analyzed using the Kruskal-Wallis, Dune and Wilcoxon tests at a 0.05 significance level. Result: A significant difference in marginal and internal adaptation were observed among restorations (p < 0.05). Superior marginal and internal adaptation was obtained in this study for alkasite whether with or without bonded over nanohybrid composite. However, RMGIC and GIC show more adaptation values among other tested groups. Also degree of monomer conversion percentage varied among restorations at different intervals. Conclusion: alkasite restorations wither with or without bonding have higher marginal and internal adaptation in comparison with nanohybrid composite but lower than that of GIC and RMGIC. Also alkasite restoration showed higher degree of conversion when compared with nanohybride composite and RMGIC after 20 second and 24 hours of polymerization. [ABSTRACT FROM AUTHOR]

Aim: To enhance mineral trioxide aggregate high plasticity (MTA HP), a commonly used dental calcium silicate cement, by incorporating selenium nanoparticles (SeNPs) known for their antioxidant and anti-inflammatory properties. The objectives included investigating the impact of SeNPs on the setting time and chemical properties of MTA HP. Materials and Methods: We performed a comprehensive study to formulate and profile SeNPs integrated into MTA HP. Diverse concentrations of SeNPs were introduced into MTA HP, and the commencement and culmination of the setting process were gauged employing a Gillmore needle cabinet. The chemical composition was validated using Fourier transform infrared spectroscopy with attenuated total reflectance and X-ray diffraction analysis. Results: The incorporation of SeNPs led to remarkable improvements. Notably, SeNPs positively affected the setting time of MTA HP, with faster setting times corresponding to higher SeNPs concentrations. Chemical analyses confirmed the successful integration of SeNPs with MTA HP. These enhancements make the material may be suitable for dental applications, especially due to its accelerated setting time. Conclusions: MTA HP incorporated with SeNPs represents a significant advancement in dental materials. Its faster setting time, combined with the antioxidant and anti-inflammatory properties of selenium, provides dental professionals with an efficient and time-saving option for complex treatments. This novel nanomaterial holds promise for improving dental procedures and patient outcomes. [ABSTRACT FROM AUTHOR]

This study aims to explore the pivotal role of green inclusive leadership (GIL) in driving sustainability efforts in the hotel industry, guided by the social exchange theory (SET). The research centers on three core objectives: firstly, evaluating how GIL directly impacts green work engagement (GWE), green organizational identification (GOI), and green organizational citizenship behavior (GOCB); secondly, examining how GWE and GOI influence GOCB; and thirdly, investigating whether GWE and GOI act as mediators in the relationship between GIL and GOCB. This study gathered data via an online questionnaire, completed by 446 front-line employees in eco-conscious five-star Saudi Arabian hotels. This study employed PLS-SEM with bootstrapping techniques to scrutinize seven hypotheses, encompassing both direct and indirect connections among study variables. The findings underscore the significant, positive influence of GIL on employees' GWE and GOI, motivating their active participation in GOCBs. Furthermore, GWE and GOI play pivotal roles in enhancing employees' engagement in GOCBs. Notably, GWE and GOI emerge as substantial mediators in the relationship between GIL and GOCB. These insights carry significant practical implications, poised to strengthen GOCB and drive sustainability initiatives in the hotel industry. [ABSTRACT FROM AUTHOR]

The four language skills of speaking, listening, reading, and writing are taught to English language learners. One of the hardest skills for EFL students to master is reading comprehension, and many of them lose marks on reading comprehension questions because they don't know how to respond to the questions in the exam. The researcher administers a questionnaire to all male and female English 101 and 102 students enrolled in the Applied College at King Faisal University in the third semester of 2023 to learn about their most frequent reading comprehension issues. This survey was created by the researcher. The questionnaire is 20 questions long and asks several questions about the respondent's reading process, linguistic proficiency, and psycholinguistic difficulties. [ABSTRACT FROM AUTHOR]

A marine-derived red alga, along with their active constituents, were actively screened for their biocontrol potential against major insect pests. The current study explored the larvicidal activity of crude methanolic extracts of the red alga Halymenia dilatata (Mx-Hd) against Aedes aegypti (Linn.), and their enzyme inhibition, repellent activity, and non-target toxicity was screened against non-target species. The toxicity of Mx-Hd to exposed larvae was dose-dependent, and it was significant at the maximum concentration of 100 ppm (parts per million) across the second, third, and fourth instars of Ae. aegypti. The LC50 and LC90 Mx-Hd concentrations for second-instar larvae were 37 and 93 ppm, respectively. Moreover, the level of major detoxifying enzymes was altered in response to the Mx-Hd treatment. The repellent activity of Mx-Hd showed maximum repellent protection at 100 ppm dosage for up to 210 min. The toxicity against non-target species showed that Mx-Hd was safe or less toxic at the prominent dosage (1000 ppm). The photomicrography results provided a prominent damage rate in fourth-instar midgut cells and tissues treated with Mx-Hd. Overall, the present study delivered an insect toxicological screening study of bioactive red alga extracts against a dengue mosquito vector, as well as a baseline for better commercialization of bioactive insecticides. Also, the bioeconomy of algal-based pesticides in managing mosquito larvae presents an exciting avenue for sustainable and eco-friendly pest control. [ABSTRACT FROM AUTHOR]

Objectives: Mechanical properties are cardinal for the long‐term clinical success of laminate veneer restorations but the selection of new restorative materials should ideally be based on clinical evidence, therefore, in vitro testing of dental materials is a good alternative to evaluate their properties and understand their behavior so this study aimed to compare and evaluate the effect of two different thicknesses and yttria percentage on the fracture resistance of laminate veneer zirconia restorations. Materials and Methods: Forty laminate veneer restoration prepared from partial sintering zirconia of 3Y (yttria), 5Y (yttria), combined 3Y&5Y (yttria), and lithium disilicate. Specimens were assigned into four main groups according to their percentage of yttria content (n = 10) and subgrouped into two thicknesses (0.5 mm thickness and 0.3 mm thickness) (n = 5) as follows: Group I, II, III, and IV (Group I for lithium disilicate (control), Group II for 3Y zirconia, Group III for 5Y zirconia, and Group IV for combined 3Y&5Y zirconia), each of them subdivided according to their thickness into two subgroups (n = 5 for each one) and resistance to fracture for each restoration was evaluated using a universal testing machine. Data were analyzed using a one‐way analysis of variance and Duncan's tests at a 5% level of significance. Results: The thickness of laminate veneer restoration significantly affects the fracture resistance value of all type of laminate veneers restorations (fracture resistance mean value was highest for 0.5 mm thickness and lower for 0.3 mm thickness restorations) and yttria percentage significantly affect fracture resistance value of zirconia laminate veneer restorations (fracture resistance mean value was highest for 0.5 mm thickness of 3Y zirconia [865 N] and combined 3Y&5Y zirconia [846 N]). Conclusions: Reducing the thickness of laminate zirconia veneer restorations to 0.3 mm reduces its fracture resistance and increasing yttria percentage had an adverse effect on fracture resistance of zirconia laminate veneer restorations.

Background Osteoarthritis (OA) is a complex degenerative articular disease that has an ambiguous pathogeny because variant risk factors participate in the process of cartilage deterioration. Genetic factors may have a role in the onset and progression of OA. Objective To investigate potential association between severity of knee OA (KOA) and Double von Willebrand factor A domains DVWA rs11718863 gene polymorphism. Methods One hundred and twenty Iraqi patients diagnosed with KOA, aged (45 years and above) and sixty healthy people (control) at the same age range, with no family history of OA were evaluated at Al-Imamein Al-Kadhimein Medical City (Rheumatology Department). The degree of severity of KOA was assessed by clinical and radiographic assessment. DVWA rs11718863 genotyping was performed using DNA sequencing (Sanger's method). Results Two different genotypes wild homozygote (TT) genotype and heterozygote (AT) appeared by genotyping of DVWArs:11718863. Highly significant difference (p<0.001) was found in distribution of the two genotypes in the three study groupsl the genotype (TT) was more frequent in control group (95.0%). Also, high significant difference (p<0.001) was noted in the two alleles (A, T) frequencies between control group and KOA patients group giving odd ratio 6.437 with 95% confidence intervals of (1.93-21.42). Conclusion Iraqi subjects carrying AT genotype of DVWA rs11718863 gene are mostly susceptible for developing of KOA and the allele A of Tyr169Asn polymorphism are more frequent in those patients indicating that allele A may be a risk factor of onset of this disease. Age and body mass index are considered risk factors of onset and progression of KOA. [ABSTRACT FROM AUTHOR]

In this special issue, we utilize feminist storytelling to highlight the experiences of diverse female psychologists. While women comprise most of the field, nonwhite women are notably underrepresented. To capture their unique accounts, 12 contributors shared their professional experiences, from which we generate recommendations on how to diversify psychology to include women of color and other underrepresented groups. This introduction frames the goals of the special issue to discuss feminist storytelling, feminism, power, authenticity, and mentorship. By including the voices of women representing a wide spectrum of identities, we hope to capture a unique blend of accounts otherwise untold. [ABSTRACT FROM AUTHOR]
