Parental attitudes towards sexual orientation and gender diversity: challenging LGBT discrimination in Australian schools.

As Australia considers legislative reform regarding the rights of religious schools to discriminate against LGBT students and staff, claims are often made that religious parents or those enrolling children in religious schools do not affirm diversity of sexuality or gender. Using a national dataset of parents (n = 2418), attitudes towards sexual orientation, gender diversity, homophobia and transphobia were examined. Across all religiosities, school sectors and attitudinal statements, significant majorities of parents reported positive attitudes (62.7%-93.5%). Only small minorities expressly reported negative attitudes (1.6%-20.2%). Pairwise religiosity comparisons between parents with children only at a secular school, versus any religious school, revealed few differences. Amongst Catholic parents, those with children at Catholic schools and those with children only at secular schools, held similar attitudes towards LGBT issues and a majority held favourable attitudes, suggesting most Catholic parents who enrol their children in Catholic schools do so despite or in ignorance of Catholic doctrine. Findings suggest a significant majority of parents sending children to religious schools hold supportive attitudes towards diverse sexual orientations, gender diversity, and actions to address homophobia and transphobia. This empirical evidence contradicts religious schools' calls for the rights to discriminate against LGBT persons based on parental values and attitudes.

Behavioral characteristics of toddlers later identified with an autism diagnosis, ADHD symptoms, or combined autism and ADHD symptoms.

Autism commonly co-occurs with attention-deficit/hyperactivity disorder (ADHD), but less is known regarding how ADHD symptoms impact the early presentation of autism. This study examined early behavioral characteristics of a community sample of toddlers later identified with autism diagnosis, ADHD symptoms, combined autism and ADHD symptoms, or neither condition. Participants were 506 toddlers who were part of a longitudinal study of children's behavioral development. Parents completed questionnaires about their children's behavior at two time points. Four groups were identified based on study measures or medical record: autism diagnosis (n = 45), elevated ADHD symptoms (n = 70), autism and ADHD symptoms (n = 30), or neurotypical development (n = 361). Relationships between early parent report of autism- and ADHD-related behaviors, social-emotional and behavioral functioning, and caregiver experience and subsequent group designation were evaluated with adjusted linear regression models controlling for sex. Significant group differences were found in measures of autism-related behaviors, ADHD-related behaviors, externalizing and internalizing behaviors, and parent support needs (p < .0001). Pairwise comparisons indicated toddlers later identified with combined autism diagnosis and ADHD symptoms had higher levels of autism-related behaviors, externalizing and internalizing behaviors, and autism-related parent support needs compared to the other groups. Toddlers with subsequent elevated ADHD symptoms or combined autism diagnosis and ADHD symptoms exhibited similar levels of ADHD-related behaviors, while both groups displayed more ADHD-related behaviors than toddlers subsequently identified with autism or those with neither condition. In this community sample, toddlers for whomcombined autism diagnosis and ADHD symptoms were subsequently identified showed a distinct presentationcharacterized by higher early autism-related behaviors, broader behavioral concerns, and higherparent support needs. Presence of ADHD symptoms (alone or in combination with autism) was associated with higher parent-reported ADHD-related behaviors during toddlerhood. Results indicate that ADHD-related behaviors are manifest by toddlerhood, supporting screening for both autism and ADHD during early childhood.

Accuracy Analysis of Digital Models from Intraoral Scanners and 3D-Printed Casts in Children and Teenagers

Purpose: The aim was to analyze the accuracy of digital models and 3D-printed casts from full-arch digital impressions using two intraoral scanners (iTeroTM and PrimescanTM). Materials and methods: A crossover reliability study was designed, scanning children and teenagers with iTeroTM and PrimescanTM. Accuracy was evaluated by measuring intercanine, intermolar, and ipsilateral canine–molar distances intraorally and comparing these measurements with those from plaster casts, digital models obtained with intraoral scanners, and 3D-printed casts. A paired comparison and a general linear model with a one-way repeated measures ANOVA procedure were carried out with a confidence level of 95% (p ≤ 0.05). Results: A total of 51 subjects were analyzed (mean age 12.35 ± 2.57). Statistical differences (p &lt; 0.05) were found in the upper and lower arch regarding accuracy in comparison to intraoral measurements, except for the iTeroTM-printed cast and canine–molar upper right and intercanine lower distances (p &gt; 0.05 for all comparisons). Regarding a comparison between reproduction methods, the plaster cast oversized the intercanine upper distance in comparison with both intraoral scanners’ digital models and the PrimescanTM-printed cast (p = 0.001), but there were no differences in the lower arch (p &gt; 0.05 for all comparisons). Conclusion: Intraoral scanners reproduce tooth structures with similar accuracy to conventional methods.

Three-dimensional assessment of the nasopharyngeal airway in Down syndrome during the mixed dentition period: a case-control study.

In this retrospective case-control study, we aimed to evaluate the nasopharyngeal airway volume of children with Down syndrome (DS) and compare the results with those of control participants well matched for sex and age. Fifteen children with DS (mean age = 9.43 ± 0.38 years; 8 boys, 7 girls) and 15 control participants (mean age = 9.51 ± 0.40 years; 8 boys, 7 girls) were enrolled. The nasopharyngeal airway volume and the cross-sectional morphology were measured with cone-beam computed tomography taken for orthodontic treatment. All measurements were assessed by analysis of covariance (ANCOVA) using Bonferroni post hoc pairwise comparison tests. Covariates were body height and body weight, and the ANB angle and the mandibular plane angle. Significance was set at P < .0019. Nasal airway, superior airway, and total airway volumes of DS participants were significantly smaller than those of the control participants in ANCOVA results adjusted for ANB angle and mandibular plane angle (P = .000). In ANCOVA results adjusted for body height and body weight, no statistically significant differences in the volume measurements were found. The results indicate that the nasopharyngeal airway volume differs between children with and without DS and that the airway volume tends to be smaller in DS children than in children without DS.

The Effect of Oral and Dental Health Status on the Self-Esteem Levels of Turkish University Youth

Objectives: This study aimed to investigate the impact of oral and dental health status on the self-esteem levels of Turkish university youth. Methods: This descriptive cross-sectional study included a sample of 962 Turkish university youth, aged 16 - 24, who met all the study criteria during the 2020 - 2021 academic year. Data were collected using a questionnaire and the Rosenberg Self-Esteem Scale (RSES). The data were analyzed with SPSS version 23.0. T-tests were used for pairwise comparisons, and one-way ANOVA was used for multiple comparisons. Results: Among the students who participated in the study, 56.7% were found to have high self-esteem, with a mean RSES score of 1.69 ± 1.62. Statistically significant differences were found between the RSES score and several factors, including decayed teeth (P &lt; 0.01), presence of halitosis (P &lt; 0.01), tooth color (P &lt; 0.01), crooked teeth (P = 0.045), and toothache (P = 0.008). It was determined that dental crookedness, decayed teeth, bad breath, dark yellow teeth, the presence of tooth fillings, and extracted teeth were negatively associated with self-esteem. However, no statistically significant differences were found between self-esteem and factors such as the presence of tooth fillings, extracted teeth, tooth brushing habits, frequency of dental visits, or snack food consumption (P &gt; 0.05). Conclusions: The results of this study reveal that poor oral care negatively impacts individuals' self-esteem. Issues related to oral and dental health, particularly concerning the appearance and condition of teeth, affect young people's relationships and self-confidence in social environments. It is crucial to develop family and school education programs, as well as national policies, particularly during childhood and university years, when attitudes toward oral and dental health are being established.

Comparison of the Accuracy and Reliability of Instrumental Shade Selection Devices and Visual Shade Selection: An in Vitro Study.

New shade-matching devices are available for clinical use, but their accuracy and reliability have not been investigated. This in vitro study compared the accuracy and reliability of a shade-matching colorimeter (Optishade), a spectrophotometer (VITA Easyshade V), and visual shade matching in simulated clinical conditions. Shade matching was conducted with two digital devices; (Optishade and Vita Easyshade) and the visual shade selection method, with a new 16-tab Vita Classical shade guide. Shade tabs were placed within a gingival matrix and measurements were taken from the central area of each shade tab enclosed in a black box to simulate the oral cavity. Visual assessments were conducted independently by two examiners. For the reliability assessment, each shade tab was measured 20 times by each examiner. Accuracy was calculated as a percentage of the matching readings with the actual shade per each tab. Data were analyzed with the one-way ANOVA test (α = 0.05) and Pairwise Comparison (Bonferroni Post hoc Test) to assess accuracy. The reliability evaluation was conducted by comparison between both examiners using mean and standard deviation; by a two-tailed t-test for the independent samples for all the three groups included in the study. The shade matching accuracy of Optishade was 97.50%, Vita Easyshade 89.38%, and visual method 62.19%. Statistically, high significant difference in accuracy (p < 0.001) was found when comparing both Optishade and VITA Easyshade with the visual method. Additionally, there was statistically significant difference in accuracy (p < 0.05) when Optishade was compared to Vita Easyshade. The reliability of the Optishade was 99.6% and Vita Easy shade was 99.38%. Statistically, showed no statistically significant difference in the reliability of shade match obtained within the same group when comparing the readings of Examiner 1 and Examiner 2 (p > 0.05). The colorimeter demonstrated the highest accuracy, followed by the spectrophotometer, and the visual shade selection method. Both digital methods investigated in this study showed comparable reliability. The results of this study emphasize the clinical advantage of digital shade-matching devices over visual shade-matching. The colorimeter offers high accuracy for shade matching and should be considered to use for shade matching especially with restorations in the esthetic zone.

The impact of various substrates, ceramic shades, and brands on the ultimate color and masking capacity of highly translucent monolithic zirconia: an in vitro study.

This study aimed to examine the impact of substrates, ceramic shades, and brands on the color and masking ability of highly translucent monolithic zirconia (HTMZ) using CIELab and CIEΔE2000 metrics. A total of 156 1-mm thick HTMZ disks in shades A1, A2, and A3 were produced using Dental Direkt and Kerox zirconia brands. Four 3-mm thick substrates (nickel-chromium alloy, non-precious gold alloy (NPG), zirconia shade A2, and resin composite shade A2) were prepared. HTMZ disks were overlaid on these substrates, and color measurements were taken with a spectrophotometer. Color differences (ΔE) were analyzed using CIELab and CIEΔE2000 formulas. The influence of brand, shade, substrate, and their interactions on ΔE values was assessed with a General Linear Model (GLM) and LSD pairwise comparison test. Spearman's correlation test examined the relationship between CIELab and CIEΔE2000 values. Results indicated that ΔEab was significantly influenced by substrate type and shade, while ΔE2000 was also affected by the ceramic brand. Mean color differences across ceramic-substrate groups were within clinically acceptable and perceptible ranges (clinically perceptible: ∆Eab ≥ 1.3 and ∆E2000 ≥ 0.8; clinically acceptable: 0.8 < ∆E2000 ≤ 1.8 and 1.3 < ∆Eab ≤ 2.7), except for NPG, which had ΔE values exceeding the perceptible range (ΔE2000: 1.1 ± 0.11 to 1.8 ± 0.31; ΔEab: 1.61 ± 0.15 to 2.16 ± 0.36). A significant correlation (r = 0.974, P < 0.001) was found between ΔEab and ΔE2000. Various ceramic brands and shades led to notable ΔE variations, yet average color differences within all ceramic-substrate groups remained clinically acceptable. Both ΔEab and ΔE2000 were reliable methods with a strong correlation for measuring color differences.

Reverberation Time in Traditional Courtyard Yue Opera Theatres

The development of traditional Chinese theatres is closely related to the development of traditional Chinese opera. The acoustic quality of the theatre plays a crucial role in the performance effect of Chinese opera. As one of the five major traditional Chinese opera genres, Yue opera has a significant number of existing traditional theatres in the Shaoxing area. This study conducted on-site measurements of the reverberation time in traditional courtyard Yue opera theatres. The results indicate that the mid-frequency EDT values in the main viewing areas range from 0.6 to 0.7 s, and T30 is around 0.7 s. Furthermore, aiming to investigate the optimal reverberation time for Yue opera performance spaces and the factors influencing preferences, subjective experiments using auralization technology and a paired comparison method were conducted. The results show that the optimal reverberation time for Yue opera performance spaces is around 0.8 s. There was no difference in the optimal reverberation time between the ordinary group and the experienced group, but the ordinary group tended to show a higher preference for shorter reverberation times. Compared to singing clips, recitation clips obtained higher preference scores for short reverberation times, indicating that audiences require higher clarity when listening to recitations.

Risk Factor for Rash in Patients Receiving Cytarabine and Idarubicin Induction Therapy for Acute Myeloid Leukemia

Background/Aim: Rash is a common adverse event (AE) observed during cytarabine and idarubicin induction therapy in patients with acute myeloid leukemia (AML). Previous studies have highlighted the challenge in predicting the onset and duration of rash. This study aimed to determine the factors that affect the onset of rash in patients receiving induction therapy for AML. Patients and Methods: This retrospective study involved 97 patients with AML who received induction chemotherapy with cytarabine and idarubicin at the Department of Hematology, Kyushu University Hospital between January 2008 and June 2022. The factors associated with rash were identified through a multivariate stepwise logistic regression analysis. Subsequently, the patient’s characteristics were compared between those with risk factors and those without risk factors using a matched pair analysis. Results: Pre-existing leukopenia [odds ratio (OR)=3.294; 95% confidence interval (CI)=1.272-8.531] and good performance status (PS=0) (OR=2.717; 95%CI=1.087-6.792) were significant risk factors for rash development. Conversely, the matched pair analysis indicated that patients with pre-existing leukopenia, excluding those with a PS score of 0, exhibited a significantly (p=0.015) higher incidence of rash than those without it. Conclusion: Both multivariate logistic regression analysis and matched pair analysis identified pre-existing leukopenia as a primary risk factor for rash development associated with cytarabine and idarubicin chemotherapy.

SITW Method: A New Approach to Re-identifying Multi-criteria Weights in Complex Decision Analysis

Multi-Criteria Decision Analysis (MCDA) addresses complex decision-making problems across various fields such as logistics, management, medicine, and sustainability. MCDA tools provide a structured approach to evaluating decisions with multiple conflicting criteria, assisting decision-makers in navigating intricate scenarios. Engaging experts is crucial for identifying multi-criteria models due to the diverse aspects of decision-making problems. Techniques such as pairwise comparisons and criterion weight assignment are commonly used to incorporate expert knowledge into decision models. Criterion weight assignment allows experts to indicate the importance of each criterion; however, issues can arise if model parameters are lost or experts become unavailable. To mitigate these issues, techniques like entropy or standard deviation can determine weights without direct expert input. In this context, the Stochastic Identification of Weights (SITW) method utilizes existing assessment samples to re-identify models and obtain weights that replicate the rankings of a reference model. This study compares information-based methods (Entropy, STD) with the SITW method in re-identifying the TRI medical function as a benchmark. The effectiveness of these methods is evaluated using Spearman's weighted correlation coefficient across various scenarios and alternative numbers. Results indicate that the SITW method provides more significant results than other methods in identifying multi-criteria weights by leveraging previously evaluated alternatives. Future research could explore broader approaches and uncertainty scenarios to ensure comprehensive decision support in complex contexts.

Cervix-Deep Rectal Temperature Differential on the Day ofOvulation is Correlated With Embryo Recovery Results in Mares.

Variations in temperature throughout the reproductive tract have been noted in many species. A recent study found the cervix-rectum temperature differential (CR-TD) in cattle was related to fertility. The present study aimed to assess the CR-TD in mares around the time of ovulation and relate it to embryo recover. Over 52 cycles, mares were inseminated with a fertile stallion and embryo recovery was undertaken on Day 7 post ovulation. Further 10 control mares were not inseminated. Rectal and cervical temperatures were measured using a precision thermometer on four or five occasions: the day of deslorelin administration and insemination, the day before ovulation, the day of ovulation (Day 0), the day after ovulation and, for inseminated mares, before embryo recovery on Day 7. One-way ANOVA showed that the CR-TD was significantly lower on the day of ovulation in the 36 positive cycles, in which an embryo was recovered, versus the 16 in which the embryo flush was negative (0.21 ± 0.17 vs. 0.40 ± 0.09°C; p < 0.001). Control cycles showed equivalent CR-TD to positive (0.13 ± 0.22 vs. 0.21 ± 0.17°C; p = 0.196) but not negative cycles (0.13 ± 0.22 vs. 0.40 ± 0.09°C; p < 0.001). A positive embryo recovery was associated with lower CR-TDs from the time of insemination and deslorelin to the day after ovulation compared to the day of embryo flushing (RM ANOVA; p < 0.001; Pairwise comparisons; p ≤ 0.01, in all cases). Rectal or cervical temperatures per se showed no significant differences between positive, negative or control cycles at any time point. In conclusion, a thermoregulatory process occurs close to ovulation which results in a lower CR-TD in cycles that produced an embryo versus those which did not. Further characterisation of TDs within the reproductive tract of the mare would increase our understanding of the conditions required for optimum fertility.

Impact of donor expanded criteria kidney transplantation on clinical outcomes and survival: A single-center experience

IntroductionThe scarcity of suitable donor organs has led to the inclusion of Expanded Criteria Donor (ECD) kidneys to augment the donor pool, despite potential concerns regarding post-transplant outcomes. MethodsThis retrospective study analyzed the clinical outcomes of a cohort of 317 kidney transplant recipients from deceased donors at a single center between 2008 and 2018. Patients were categorized into ECD and Standard Criteria Donor (SCD) groups, with primary nonfunctioning grafts excluded. Comprehensive laboratory evaluations were conducted, including HLA typing and serum creatinine levels. Immunosuppressive regimens were standardized, and statistical analyses were performed using the SPSS program. ResultsThe sample consisted of 83 (26.18 %) patients who received kidney transplants from ECDs and 234 (73.82 %) from SCDs. The ECD group showed a longer cold ischemia time (p = 0.019) and a higher rate of delayed graft function (DGF) compared with the SCD group. No significant differences were observed in graft survival (p = 0.370) or patient survival (p = 0.993) between the ECD and SCD groups. However, differences in graft survival were noted between the groups when stratified by DGF status: ECD with DGF vs. ECD without DGF (p = 0.029), ECD with DGF vs. SCD with DGF (p = 0.188), ECD with DGF vs. SCD without DGF (p = 0.022), ECD without DGF vs. SCD with DGF (p = 0.014), ECD without DGF vs. SCD without DGF (p = 0.340), and SCD with DGF vs. SCD without DGF (p = 0.195). No differences in patient survival rates were observed among these groups for all pairwise comparisons (p > 0.05) when stratified by donor criteria and DGF status. ConclusionsGraft and patient survival rates were comparable between ECD and SCD kidney transplant recipients.

Quantifying canine tissue stiffness change patterns using shear-wave elastography: implications for time of death estimation

ABSTRACT This study investigates the applicability and reproducibility of shear-wave elastography (SWE) in detecting changes in tissue stiffness of canine carcasses. SWE was performed on six canines by two operators. The target organs were liver, spleen, kidney, and thigh muscles. SWE was performed ante-mortem and up to 48-hours post-mortem at specific intervals. The Mann-Whitney U-test and Spearman correlation coefficient showed insignificant correlation between gender and weight with shear-wave velocity (SWV) in ante-mortem scans. The Kruskal-Wallis H-test showed significant differences in SWV for all organs. Intraclass correlation coefficient (ICC) showed excellent correlation for all target organs except for kidneys. Pairwise comparison showed a similar SWV trend for abdominal organs. Accuracy metrics were calculated for determining the post-mortem interval using SWV values. The liver had the highest accuracy (0.69–0.83) across different post-mortem interval thresholds within the cut-off values of ≥2.0 m/s, 1.8–2.0 m/s, <1.8 m/s indicating ≤6 hours post-mortem, 12–18 hours post-mortem and >18 hours post-mortem. The spleen, kidney and thigh muscle demonstrated moderate-to-poor accuracy within the same cut-off parameters. Post-mortem SWV changes in canine solid organs, and soft tissues, particularly the liver, demonstrate a reproducible pattern, which may have value in determining the post-mortem interval.

Enhancing Physical Fitness in Elite Field Hockey Players with A Twelve-Week Functional Training Program: A Cluster Randomized Control Trial.

This study aimed to explore the impact of functional training on the physical fitness of young elite field hockey players. The study comprised 40 young elite male field hockey players with the following characteristics (mean ± SD age: 21.5 ± 0.8 years; height: 176.9 ± 2.6 cm; weight: 68.4 ± 5.1 kg; BMI: 21.8 ± 1.3; training experience: 51.2 ± 5.4 months). Twenty participants were allocated to two groups: the functional training group (FTG) and the control training group (CG). Each group received 60-minute training sessions three times per week for 12 weeks. Generalized estimating equation analysis and a Bonferroni test for pairwise comparisons were used to assess the intervention's efficacy. Before the start of the exercise program, no statistically significant differences were observed in physical fitness measures between the FTG and CG (p > 0.05). However, by the sixth week, a significant difference appeared in both the T-Agility test (p < 0.001) and endurance (p = 0.024) between the two groups, while no notable distinctions were detected in other fitness parameters (p > 0.05). After a 12-week training program, the FTG demonstrated improvements in all physical fitness measures [flexibility (p < 0.001); Illinois agility test (p < 0.001); T-agility test (p = 0.020); endurance (p < 0.001)] except speed, which exhibited no significant impact (p = 0.175). Notable enhancements in T-agility and endurance were evident after just six weeks of functional training, and a 12-week functional training regimen showed superiority over standard training approaches in young elite male field hockey players. These findings encourage the efficacy of functional training exercises over traditional methods in enhancing athletes' fitness parameters.

Comparative Effectiveness of Second-Line Antihyperglycemic Agents for Cardiovascular Outcomes: A Multinational, Federated Analysis of LEGEND-T2DM

BackgroundSodium-glucose cotransporter 2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) reduce the risk of major adverse cardiovascular events (MACE) in patients with type 2 diabetes mellitus (T2DM). However, their effectiveness relative to each other and other second-line antihyperglycemic agents is unknown, without any major ongoing head-to-head clinical trials. ObjectivesThe aim of this study was to compare the cardiovascular effectiveness of SGLT2is, GLP-1 RAs, dipeptidyl peptidase-4 inhibitors (DPP4is), and clinical sulfonylureas (SUs) as second-line antihyperglycemic agents in T2DM. MethodsAcross the LEGEND-T2DM (Large-Scale Evidence Generation and Evaluation Across a Network of Databases for Type 2 Diabetes Mellitus) network, 10 federated international data sources were included, spanning 1992 to 2021. In total, 1,492,855 patients with T2DM and cardiovascular disease (CVD) on metformin monotherapy were identified who initiated 1 of 4 second-line agents (SGLT2is, GLP-1 RAs, DPP4is, or SUs). Large-scale propensity score models were used to conduct an active-comparator target trial emulation for pairwise comparisons. After evaluating empirical equipoise and population generalizability, on-treatment Cox proportional hazards models were fit for 3-point MACE (myocardial infarction, stroke, and death) and 4-point MACE (3-point MACE plus heart failure hospitalization) risk and HR estimates were combined using random-effects meta-analysis. ResultsOver 5.2 million patient-years of follow-up and 489 million patient-days of time at risk, patients experienced 25,982 3-point MACE and 41,447 4-point MACE. SGLT2is and GLP-1 RAs were associated with lower 3-point MACE risk than DPP4is (HR: 0.89 [95% CI: 0.79-1.00] and 0.83 [95% CI: 0.70-0.98]) and SUs (HR: 0.76 [95% CI: 0.65-0.89] and 0.72 [95% CI: 0.58-0.88]). DPP4is were associated with lower 3-point MACE risk than SUs (HR: 0.87; 95% CI: 0.79-0.95). The pattern for 3-point MACE was also observed for the 4-point MACE outcome. There were no significant differences between SGLT2is and GLP-1 RAs for 3-point or 4-point MACE (HR: 1.06 [95% CI: 0.96-1.17] and 1.05 [95% CI: 0.97-1.13]). ConclusionsIn patients with T2DM and CVD, comparable cardiovascular risk reduction was found with SGLT2is and GLP-1 RAs, with both agents more effective than DPP4is, which in turn were more effective than SUs. These findings suggest that the use of SGLT2is and GLP-1 RAs should be prioritized as second-line agents in those with established CVD.

High genetic diversity in anguillid glass eels across three Southeast Asian countries revealed through mitochondrial DNA D-loop sequences, with notes on population structure

Understanding the genetic diversity and population structure of anguillid eels is crucial for effective management. In this study, we used the mitochondrial DNA (mtDNA) D-loop marker to identify anguillid glass eels and assessed their genetic diversity across six sampling sites spanning three Southeast Asian countries. We also examined the population structures of Anguilla marmorata and A. celebesensis. We validated nine distinct species and subspecies of anguillid eels from 465 specimens collected in Indonesia (n=246), the Philippines (n=119), and Vietnam (n=100). High gene diversities were observed across the species, ranging from 0.979 (A. celebesensis) to 1.000 (A. bicolor bicolor, A. marmorata, and A. interioris). Correspondingly, nucleotide diversity values were relatively low, varying from 0.036 (A. marmorata) to 0.057 (A. interioris). A. marmorata (n=162) displayed a broad distribution, being observed across all six sites, with a significant yet low average fixation index of 0.05755. Pairwise comparisons of FST values between Cimandiri and other locations (except for Cagayan) were relatively high and statistically significant (p<0.01), indicating significant genetic differentiation of Cimandiri samples compared to most locations in this study. On the other hand, A. celebesensis (n=110), exhibited a non-significant and low fixation index (0.007), indicating no genetic differentiation in samples from Poso and Poigar Rivers, Indonesia. Our findings highlight the essential need for coordinated management strategies among regions that share common stocks. Additionally, this study underscores the efficacy of the mtDNA D-loop in precisely identifying glass eel species/subspecies and elucidating the genetic diversity and population structure of tropical anguillid eels.

Potential for large losses of carbon from non-native conifer plantations on deep peat over decadal timescales

Peatland drainage is a large source of anthropogenic CO2 emissions. While conversion to agriculture is widely acknowledged to lead to “irrecoverable” carbon (C) losses, in contrast the C impacts of peatland forestry are poorly understood, especially in intensively managed plantations. Losses of C from peat oxidation are highly variable and can be compensated for by gains of C in trees, depending on the lifecycle of the timber and timescale considered. Here, we used ITRAX scanning to enable rapid detection of the Hekla 4 cryptotephra layer as a reliable chronological marker above which peat properties and C stocks could be compared between open and afforested blanket bog cores in the Flow Country of Northern Scotland. At one site, Bad a’ Cheò, we combine replicated core pair comparisons (n = 19) with timber extraction data to derive net ecosystem C balance over the lifetime of the plantation. Here the reduction in peat C carbon storage above Hekla 4 in afforested samples (67 t C ha−1) is only partially compensated by tree C sequestration (47 t C ha−1), leading to a net ecosystem C balance indicating a loss of 20 t C ha−1 over the 50 years since the plantation was established. At that site, ~65 % of tree C rapidly returned to the atmosphere, as it was primarily used for heat and power generation. Across the wider Flow country region, a simplified paired sampling method was adopted at eight further sites, finding a either a loss or negligible change in peat C storage above Hekla 4 in afforested samples with a mean loss of 86 t C ha−1 and median loss of 50 t C ha−1. This study suggests that potentially substantial C losses have been an unintended consequence of non-native conifer afforestation over deep blanket bogs.

Identification of groundwater potential zones using geospatial technologies in Meki Catchment, Ethiopia

ABSTRACT Mapping groundwater potential zones helps in precisely planning well drilling. The Meki Catchment is currently experiencing irrigation expansion and water scarcity challenges, creating a strong need for groundwater exploitation. The goal of this study was to identify groundwater potential zones (GWPZs) in the Meki Catchment using geospatial technologies to enhance water resource management and support sustainable development in the region. Eight thematic components were used in this analysis. Analytical Hierarchy Process (AHP) method was applied to ensure consistency in judgments through paired comparisons. Weighted overlay analysis was then used to evaluate the GWPZs. The study found that out of the total Meki Catchment area (226,333.26 ha), 30.68% (69,448.31 ha) has high potential, and 34% (76,963.33 ha) has good potential. Validation was conducted using ground truth data, considering existing water point field data from borewells and springs. The results of this study can help prioritize strategies to ensure the sustainable use of groundwater in the area. Drilling organizations can utilize these findings as a resource for feasibility studies in groundwater prospecting projects to locate well sites. The validation results demonstrate that potential groundwater zones can be identified more accurately using GIS and RS approaches at a lower cost.

The Relationship of Immune Markers with Severity and Heritability of Depressive Disorder: A Cross-Sectional Hospital-Based Study from North India

Background: Inflammatory response plays a pivotal role in the pathophysiology of depression. With this background, we planned this study to see if immune markers, interleukin 6 (IL-6), and erythrocyte sedimentation rate (ESR) are raised in subjects with major depressive disorder (MDD) and compare its level with healthy controls and first-degree relatives of subjects. We also explored if variation in the level of these markers was related to the severity of depression. Methods: This comparative observational study included 120 subjects, who were divided into three groups of 40 individuals each. Group 1 was the MDD group, group 2 was the healthy first-degree relative group, and group 3 was the healthy control group. All the subjects were then made to undergo estimation of IL-6 (pg/mL) and ESR (mm/h) from our hospital biochemistry lab. The patients in group 1 were additionally screened for the severity of depression. Results: The mean IL-6 and ESR measure within the MDD group was 9.20 ± 13.40 (pg/mL) and 5.90 ± 5.35 (mm/h), respectively. We found that the mean and median values of both IL-6 and ESR were highest in the MDD group as compared to other groups, which were statistically significant ( p &lt;0.05). A pairwise comparison found no significant difference in the IL-6 and ESR scores among the healthy controls and healthy first-degree relatives. The mean of IL-6 was highest in individuals with moderate severity of depression, while the mean of ESR was highest in individuals with severe depression. Conclusion: The immune markers, IL-6 and ESR, were significantly raised in the MDD group; however, the levels did not correlate significantly with the differential severity of the depressive disorder as per Hamilton depression rating scale (HAM-D) scores.

ADMINISTRATIVE AND LEGAL GUIDELINES FOR STANDARDIZATION OF FINANCIAL REPORTING OF ENTERPRISES AS SOCIO-ECONOMIC SYSTEMS

This article aims to present an approach for determining the most effective administrative and legal guidelines for the standardization of financial reporting in modern open socio-economic systems. It emphasizes the current state of financial reporting of these open socio-economic systems at the time of analysis and the application of the proposed approach. As the most common form of open socio-economic systems today, enterprises are taken as the basis. The method of multi-criteria decision analysis (MCDA), which encompasses various approaches to decision-making based on multiple criteria, including hierarchical analysis, was applied. In addition to its comprehensiveness, the method of pairwise comparison, which involves the use of two elements for comparison, was also applied. Experts were involved in the assessment and determination of the administrative and legal guidelines. As a result, an approach to forming key administrative and legal guidelines for the standardization of financial reporting was developed, which, unlike other similar approaches, aims to take into account external environmental factors and the changes they bring in order to try to adjust financial reporting standardization policies in complex development conditions. The practical value is revealed in the possibility of application by state bodies and structures involved in the development and establishment of financial reporting standards in Ukraine.
