A Dosimetric Comparison Study for Blood Irradiation Employing Different Medium and Algorithms in Clinical Linear Accelerator.

To identify a suitable approach for blood irradiation other than the commonly used water medium and to study the impact of different algorithm dose computations. Water is the commonly used medium for blood irradiation. In this study computed tomography scans were taken with locally made blood irradiation phantoms other than water, by using air, rice powder and thermocole using parallel beam for 25 Gy. Plans were recalculated for different algorithms such as collapsed cone (CC), Monte Carlo (MC) and pencil beam (PB). The dose-volume parameters and measured doses were collected and analyzed for each medium and algorithm. The monitor unit (MU) for rice powder and water are close (2461±57 and 2469±61, respectively), with a maximum dose of 28.0±1.8 and 28.0±1.9 Gy. The PB algorithm resulted in lower monitor unit values regardless of the medium used, generating values of 2418, 2406, 2382, and 2362 for water, rice powder, air, and Thermocol, respectively. A significant increase in dose was observed irrespective of the medium used when the MC algorithm was employed, with a maximum of 30.26 Gy in rice powder; a smaller dose was used when the CC algorithm was employed, with 26.3 Gy in water medium. The average maximum doses of all groups were equal using the one-way Anova statistical test. Regarding the impact of field size, rice powder appears to have consistent doses across various field sizes, with slight increases as field size grows, which is similar to water. While water is the conventional medium, this study highlights the potential benefits of rice powder, such as eliminating the risks associated with bubble formation and water spillage, which can lead to equipment malfunction and safety hazards. Although previous studies have explored rice powder as a bolus and tissue-equivalent material, this study uniquely applies this knowledge to blood irradiation, an area where rice powder has not been thoroughly investigated.

Evaluation of Etching Time Effect on Shear Bond Strength of Orthodontic Brackets Bonded with Self-Adhesive Composite: An in-Vitro Study

Introduction: Precise acid etching of the tooth surface is a significant factor in the strength of the bracket bond. The current study aimed to determine the effect of different application times of acid etching on the shear bond strength of metallic orthodontic brackets under controlled laboratory conditions. Methods: Sixty intact premolar teeth were selected for this in-vitro study. The samples were divided into four groups based on the different acid etching times: 20, 25, 30, and 35 seconds. The teeth surfaces were etched with 37% phosphoric acid according to the specified times, and brackets were bonded to the enamel surface using GC Ortho connect composite. Shear bond strength values of the brackets was measured using a Universal Testing Machine. The amount of Adhesive Remnant Index was also observed using a stereomicroscope. Additionally, the surface roughness of the tooth enamel after bracket bonding was examined using SEM. The results related to shear bond strength were analyzed with one-way ANOVA statistical test and using SPSS version 16 software. The non-parametric Kruskal Wallis (Wallis-Kruskal) test was also used to check the frequency of ARI index. Results: The highest shear bond strength was observed at 25 seconds, and the lowest at 30 seconds. However, there was no significant difference in the shear bond strength of brackets was observed among the four groups (p=0.186). The highest ARI score was observed at 35 seconds, and the lowest at 20 seconds. No statistically significant difference was observed in the ARI scores in different groups. SEM images revealed that the enamel surface porosity was highest at 20 seconds. Conclusion: The results indicate that the shear bond strength and ARI at different acid etching times do not significantly differ. Therefore, orthodontic bracket bonding can be performed with less acid etching time.

The Effect of a Combination of Ethanol Extract from Leaves and Flowers of Plumeria acuminate L. Against Aedes aegypti Larvae

Aedes aegypti is the primary vector that causes dengue virus (DENV) infection. Ae. aegypti resistance to abate (Temephos) has occurred in Indonesia and several other countries. Innovations are needed to develop alternative ingredients that can be used as natural larvacides. The Plumeria acuminate L. is an Indonesian plant with metabolites that have the potential to act as larvicides. This study aims to determine the potential combination of ethanol extract of P. acuminate L. leaves and flowers as a larvicide for A. aegypti. A laboratory experimental study with a post-test-only control group design was carried out on Ae. aegypti larvae instar III. The larvicide test was carried out according to WHO standards in 2005 with concentrations of 10000, 7500, 5000, and 2500 ppm, as well as control (water and 1% DMSO), with 20 larvae for each concentration. The observation was carried out at the 24th and 48th hours with 3 repetitions. Larval mortality data was analyzed using one-way ANOVA statistical tests to determine significant differences and lethal concentrations (LC50 and LC90) were calculated using probit analysis using SPSS software. The mortality of Ae. aegypti larvae due to the administration of a combined ethanolic extract of P. acuminate L. leaves and flowers was the highest at doses of 10000 and 7500 ppm, which was 100% with lethal concentrations of LC50 and LC90 of 3364.715 and 6293.759 ppm at the 24th hour observation, whereas at the 48th-hour observation, lethal concentrations were detected at 1767.998 and 2941.138 ppm, respectively. One-way ANOVA analysis test showed a significant difference in Ae. aegypti larval mortality due to the administration of a combined ethanol extract of P. acuminate L. leaves and flowers at 24th-hour observation (p = 0.000) and (p = 0.013) at 48th hour observation. The combination of ethanol extract of P. acuminate L. leaves and flowers showed larvicidal activity against Ae. aegypti larvae as evidenced by larvae mortality which were influenced by concentration and observation time.

Administration of low dose intranasal ketamine exerts a neuroprotective effect on whole brain irradiation injury model in wistar rats.

Exposure to ionizing radiation leads to oxidative stress and neuroinflammation, resulting in neurocognitive impairments. Adverse effects are also associated with glutamate-induced excitotoxicity due to alterations in the composition of glutamate receptors. Ketamine, which is a noncompetitive NMDA glutamate receptor antagonist, has been stated to exert an impact on glutamatergic receptors. This study aims to reveal the possible alleviating or preventive effects of ketamine, which maintains glutamate homeostasis and decreases neurodegeneration, in a radiation-induced neurotoxicity model. Twenty-one female Wistar Queryrats were included in the study and 14 of these underwent whole brain irradiation (IR) with a 20 Gray single dose. Animals were allocated into three groups. Group 1: Normal control; Group 2: Placebo / IR + Saline; Group 3: IR + Ketamine. Ketamine was administered in addition to IR to rats in Group 3. The one-way ANOVA statistical test was used to compare groups. The value of p < 0.05 was considered statistically significant. When administered in addition to irradiation, ketamine treatment significantly increased scores in the three-chamber sociability test, open field test, and passive avoidance learning test. It also raised neuron counts in the hippocampal CA1 and CA3 regions as well as in Purkinje cells, and enhanced levels of brain-derived neurotrophic factor and tyrosine receptor kinase-B. Furthermore, ketamine administration resulted in decreased levels of glial fibrillary acidic protein, malondialdehyde, and tumor necrosis factor-alpha, indicating a reduction in neuroinflammation and oxidative stress. Ketamine exerted a significant protective impact on radiation-induced neurocognitive impairments and enhanced social-memory capacity by reducing neuronal loss, oxidative stress, and neuroinflammation. Our findings suggest that ketamine is beneficial in the treatment or prevention of neurodegeneration via the regulation of the BDNF/TrkB signaling pathway besides decreasing neuroinflammation and blocking NMDA receptors.

Comparison of Carbon Storage in Forested and Non-Forested Soils in Tropical Wetlands of Caimanera, Colombia, and Llano, Mexico

Mangrove forests are considered to be the most productive ecosystems on the planet due to the multiple ecosystem services they offer, both environmental economic, and social; however, their area in recent years has been decreasing due to anthropogenic activities such as urbanization and deforestation. These activities alter the normal cycle of carbon stored in sediments, which is considered their main function to counteract climate change. Therefore, the objective of this research was to compare the carbon storage capacity and coverage in forested and non-forested sites of two tropical wetlands located in Colombia (the Caimanera) and Mexico (the Llano). Methodologically, we began by identifying the coverages and determining the area in the wetlands with Sentinel-2A satellite images and a supervised classification; subsequently, soil cores were extracted in all the coverages to a depth of 70 cm and the apparent density (AD), the percentage of organic carbon (OC), and the density of carbon in the soil were determined. For analysis of the variables, a trend graph was constructed between carbon density and depth with descriptive statistics, using one-way ANOVA to establish which coverage and wetland were the most significant concerning carbon storage. The results of the supervised classification showed that Rhizophora mangle and Avicennia germinans are the dominant species, also finding deforested areas in both wetlands. The one-way ANOVA statistical test indicated that the Caimanera, with the percentage of organic carbon (18.4 ± 1.19%), is 1.57 times greater than of the Llano mangrove swamp with (11.7 ± 0.748 MgC/ha). Through the trend graph, it was observed that the carbon density of the forested area of the Caimanera ranged from 120 to 140 MgC/ha, which is higher than in the deforested areas of the same wetland between 40 and 60 MgC/ha, and the homologous areas of the Llano wetland. The results suggest that deforested areas are sources of greenhouse gas emissions because they contain less carbon than forested areas. Therefore, it is concluded that the Caimanera and the Llano wetlands have the same mangrove species and that the average organic carbon stored in their soil is below the average of other mangrove forest soils in the American continent; it is recommended that the findings of this work be considered for the carbon balances by continent and the characterization of mangrove species according to their carbon storage capacity.

Formulation and Characterization of New Experimental Dental Composites with Zirconium Filling in Different Forms.

Short glass fibers are generally used in posterior dental restorations to enhance the mechanical properties and improve the material microstructure. Two resin-based composites (S0 and SF) were formulated and characterized to investigate the influence of zirconium in their characteristics and properties. The organic part of the investigated materials was the same (BisGMA, TEGDMA, and a photochemical polymerization system), and in the inorganic part, besides quart, glassA, and hydroxylapatite with Zn, sample S0 contained strontium glass with zirconium and sample SF contained fiber powder of chopped zirconium. The samples were characterized by the degree of conversion (DC), mechanical properties, water sorption (WS), scanning electron microscopy (SEM), atomic force microscopy (AFM) before and after the WS test, and antimicrobial properties. The results obtained were subjected to one-way ANOVA and Tukey's statistical tests. Both samples had a high DC. Regarding the mechanical properties, both samples were very similar, except DTS, which was higher for the composite without fibers. After 14 days, the WS value of the SF sample was lower than that of the S0 sample. Water caused significant changes in the topography of the SF sample, but thanks to its antimicrobial properties and the diffusion phenomenon, SF had a more pronounced antimicrobial effect. This study shows that the addition of appropriate amounts of Sr-Zr-glass powder gives the material in which it is added similar properties to material containing chopped zirconium glass fiber powder. According to the antimicrobial test results, resin composites containing experimental zirconia fillings can be considered in future in vitro clinical studies for posterior reconstructions with significantly improved mechanical properties.

First Report of Binucleate Rhizoctonia AG-G Causing Grapevine (Vitis Vinifera) Trunk Diseases in California Nurseries.

Grapevine Trunk Diseases (GTD) are caused by a consortium of fungal pathogens that affect the biological functions of the vascular system of mature and young grapevines (Gramaje et al. 2018). We conducted surveys to profile GTD pathogens in California grapevine nurseries and collected 784 cuttings of cvs. Cabernet Sauvignon and Chardonnay grafted on 1103P rootstock. Several vines exhibited wood necrotic lesions and cankers at the graft union and the root ball (Figure 1A). Symptomatic wood tissues were cultured on PDA medium and after two weeks of incubation at room temperature (22°C), several known GTD pathogens were recovered. We also identified Rhizoctonia from 42 of the 784 vines (5.3% incidence) based on the morphological characteristics of a brown pigmented mycelium (Figure 1B), hyphae branched at a right angle with constrictions at the branch point (Figure 1C) and absence of spores (González García et al., 2006). A subsample of four isolates (DCHG2B, DCSG22R, JCSG9B, and JCHG12B) were randomly selected for further DNA-based taxonomic identification and pathogenicity evaluation to grapevine. The ITS and beta tubulin regions were amplified using the ITS1/ITS4 and B36F/B12R primer sets, respectively (González et al. 2006), and sequences were deposited in the NCBI database (Accession numbers: OR052655, OR052656, OR052657, OR052658 and OR059207, OR059208, OR059209, OR059210). Sequences displayed >99% and >96% identity with the respective ITS and beta tubulin sequences of the binucleate Rhizoctonia AG-G specimen C-653 (González et al. 2006). A phylogenetic tree constructed using the Neighbor-Joining method indicated a 100% bootstrap support with the binucleate Rhizoctonia AG-G (Figure 2). Pathogenicity of the binucleate AG-G Rhizoctonia were confirmed on two separate technical replicates using standard methods. For each replicate, one-year-old rootstock 1103P were wounded with sterile drill bits and inoculated with a single 5 mm diameter agar plug collected from Rhizoctonia growing cultures, while control vines were inoculated with sterile agar. The first replicate lasted 28 weeks with (DCHG2B, DCSG22R) inoculated on seven vines. The second bioassay lasted 24 weeks with two additional isolates (JCSG9B, JCHG12B) inoculated on twelve vines. Rhizoctonia-inoculated vines developed wood symptoms similar to those observed on cuttings in nurseries, with necrotic lesions lengths significantly longer than the controls (First replicate: 3.5  0.4 cm vs. 1.3  0.6 cm; Second replicate: 6.8  0.8 cm vs. 1.1  0.2 cm), based on one-way ANOVA statistical test (P value < 0.05). Rhizoctonia isolates recovery from wood necrotic lesions were confirmed by ITS sequencing, thereby fulfilling Koch's postulate. Several binucleate Rhizoctonia anastomosis groups, including AG-G, have been found to cause root rot and stem necrosis in plant nurseries (Aiello et al., 2017; Rinehart et al., 2007). Rhizoctonia has also been reported to be associated with grapevine nurseries in Europe (Pintos et al., 2018), South Africa (Halleen et al., 2003) and Australia (Walker, 1992). However, the multinucleate Rhizoctonia solani was the only species confirmed to cause root rot on grapevine (Walker, 1992). Our data suggests that the binucleate Rhizoctonia from the AG-G anastomosis group also cause wood necrosis in grapevine. Those findings warrant further studies on the complexity of Rhizoctonia anastomosis groups in nursery and their aggressiveness to grapevine.

It can be concluded that there is an effect of 50% Averrhoa bilimbi L. gel on the histological response of the pulp, there is an effect of 10% carbamide peroxide on the histological response of the pulp, and there is a significant difference between 10% carbamide peroxide and 50% Averrhoa bilimbi L. gel.

Multi-objective optimization of mixed-model assembly lines incorporating musculoskeletal risks assessment using digital human modeling

In line with Industry 5.0, ergonomic factors have recently received more attention in balancing assembly lines to enhance the human-centric aspect. Meanwhile, today’s mass-customized trend yields manufacturers to offset the assembly lines for different product variants. Thus, this study addresses the mixed-model assembly line balancing problem (MMALBP) by considering worker posture. Digital human modeling and posture assessment technologies are utilized to assess the risks of work-related musculoskeletal disorders using a method known as rapid entire body analysis (REBA). The resulting MMALBP is formulated as a mixed-integer linear programming (MILP) model while considering three objectives: cycle time, maximum ergonomic risk of workstations, and total ergonomic risks. An enhanced non-dominated sorting genetic algorithm (E-NSGA-II) is developed by incorporating a local search procedure that generates neighborhood solutions and a multi-criteria decision-making mechanism that ensures the selection of promising solutions. The E-NSGA-II is benchmarked against Epsilon-constraint, MOGA, and NSGA-II while solving a case study and also test problems taken from the literature. The computational results show that E-NSGA-II can find promising Pareto front solutions while dominating the considered methods in terms of performance metrics. The robustness of E-NSGA-II results is evaluated through one-way ANOVA statistical tests. The analysis of results shows that a smooth distribution of time and ergonomic loads among the workstations can be achieved when all three objectives are simultaneously considered.
