3D reconstruction of foot metatarsal bones of women using CT images

Bone morphology is a fundamental factor in human anatomy. However, foot and ankle bones have yet to be adequately evaluated in 3-dimensional. It is essential to present the biometric data of anatomical structures. This study formed 3D models of the metatarsal bones of the feet of young women using image processing techniques to examine biometric measurements and determine morphology on these 3D models. This study investigated bone lengths in the metatarsal bones of women feet in Türkiye. A total of ten young female subjects were included as the test group to measure the lengths of their foot metatarsal bones using CT (Computed Tomography) scans, and 20 feet (left/right) were examined. The parameters that were used for the analyses were detector collimation of 64x0.5 mm, section thickness of 0.5 mm, current of 100 mA, tube voltage of 120 kVp, and pixel spacing of 512x512 pixels with a monochrome resolution providing 16-bit gray levels. CT images were processed, and a 3D metatarsal reconstruction was gathered. Then, the biometric measurements were calculated on this 3D model. For the lengths of the volunteers' right/left foot metatarsal bones, statistically significant differences were calculated using a one-sample t-test. For the female metatarsal bones of the left and right feet, statistically significant differences in length were calculated on 3D models. The mean results of the metatarsal length measurements were MT1(metatarsal): 59.52±1.42 mm, MT2: 70.45±1.82 mm, MT3: 66.25±1.82 mm, MT4: 65.12±1.81 mm and MT5: 63.63±1.81 mm. The level of statistical significance was accepted as p <0.05 for the one-sample t-test conducted for each metatarsal bone. The lengths of the right foot metatarsal bones were different from those of the left foot metatarsal bones in the sample. However, this difference was approximately one-tenth of a millimeter. The shortest bone was MT1, and the longest bone was MT2. These measurements are consistent with the anatomical information in the literature. The 3D models from the CT images and the biometric measurements of the metatarsal bones were found to be reliable and accurate.

Cross-project software defect prediction through multiple learning

Cross-project defect prediction is a method that predicts defects in one software project by using the historical record of another software project. Due to distribution differences and the weak classifier used to build the prediction model, this method has poor prediction performance. Cross-project defect prediction may perform better if distribution differences are reduced, and an appropriate individual classifier is chosen. However, the prediction performance of individual classifiers may be affected in some way by their weaknesses. As a result, in order to boost the accuracy of cross-project defect prediction predictions, this study proposed a strategy that makes use of multiple classifiers and selects attributes that are similar to one another. The proposed method's efficacy was tested using the Relink and AEEEM datasets in an experiment. The findings of the experiments demonstrated that the proposed method produces superior outcomes. To further validate the method, we employed the Wilcoxon sum rank test at 95% significance level. The approach was found to perform significantly better than the baseline methods.

Authentication and verification in arbitration proceedings

The extensive and intensive development of digital technologies is a constant process that co-occurs with the same steady increase in the level of social significance of the justice process. One of the cornerstones in integrating individual technological solutions into the justice administration ecosystem is the development of technologies that can carry out many procedures remotely. These problems indicate a real need to develop a comprehensive scientific understanding of verification and authentication. This study aims to analyze the concepts of verification and authentication in the context of modern arbitration proceedings in Russia and define issues arising from the digitalization of procedural relations. The authors concluded on the possibility of convergence of arbitration institutions and state courts, the creation of a unified information system aimed at increasing the accessibility of arbitration proceedings, which correlates with the reduction of judicial workload in state courts, as well as the prospects of integration of authentication and verification mechanisms in arbitration proceedings.

Employee Dietary Initiative Improved Chronic Symptoms

With the awareness that the Standard American Diet is a critical contributor to chronic diseases, this initiative aimed to assess the effects of a 28-day dietary challenge health care improvement project on health system employee energy level, sleep quality, gastrointestinal function, ability to concentrate, and aches/pains, including the impact of adherence level, during a period of restricted intake of gluten, dairy, and sugar offered annually from 2021 to 2023. A total of 754 employees completed the pre-challenge survey; analyses included 354 employees who completed both pre-challenge and post-challenge surveys in at least 1 year of this project. Wilcoxon signed rank tests compared presurvey and postsurvey responses to self-reported energy level, sleep quality, gastrointestinal function, ability to concentrate, and aches/pains. Analysis of variance with Tukey’s honestly significant difference tests compared self-reported adherence level with change scores, with η2 representing effect size. In each challenge year, the mean rank levels of energy, sleep quality, gastrointestinal function, concentration, and aches/pains improved significantly between pre-surveys and post-surveys (all P<.001). Although an association between significant positive change and diet adherence level was found for all items in at least 1 challenge year, those who mostly or completely adhered to the challenge diet restrictions reported significantly greater positive change in energy levels and gastrointestinal symptoms than those who did not or minimally adhered in all challenge years, with small to medium effect sizes. In conclusion, Essentia Health’s employee challenge appeared to improve self-reported outcomes in 5 symptom domains, with energy levels and gastrointestinal symptoms correlating most favorably to adherence to the challenge. These findings have health and cost implications, which could be confirmed by formal research in employee and other populations.

Millennial to orbital scale Indian summer monsoon evolution inferred from grain size end-members in Tengchongbeihai wetland, southwestern China

Understanding the Indian summer monsoon (ISM) variabilities under different climatic constraints on various timescales is crucial for socio-economic stabilization within the ongoing warming globe. However, aside from stalagmite records, very few terrestrial paleoclimate archives have been used to explore the last glacial ISM characteristic, which limits our understanding of the ISM natural behaviors and their underlying mechanisms on longer timescales. Here, we present a grain size end-member analysis for Tengchongbeihai wetland sediments from southwestern China to investigate the paleo-hydroclimate changes since the late MIS3. The overall low fine silt content before ∼19 cal ka BP resulted from weak catchment erosion indicating weak ISM during cold glacial while the increasing trend thereafter indicates the ISM strengthened during the last deglaciation and Holocene. Such an orbital ISM evolution resembles to the insolation gradient between 25°N and 25°S during the boreal summer periods, which implies the transequatorial insolation difference could be an alternative explanation for the orbital scale low latitude hydroclimate changes. The remarkable peaks of coarse component around ∼ 9, 12, 19, 26, 32, 37 and 42 cal ka BP were related to significant water level descending indicating the millennial ISM collapse corresponding to the YD and Heinrich events. However, the absence of sawtooth feature as the NGRIP δ18O and the well correspondence to the Indian Ocean sea surface temperatures (SSTs) of the ISM collapses evidence the modulation of low latitude forcing on the North Atlantic climate effects on the millennial scale hydroclimate variabilities.

Objective > To assess the allele rs 1143634 in IL-1β and rs1800587 in IL-1α in patients for orthodontically induced external apical root resorption (EARR).Material and methods > Intra-oral periapical radiograph (IOPA) of maxillary incisors of 142 Patients were evaluated for resorption at two time points; before the start of fixed mechanotherapy (T1) and after one year of treatment (T2). The individuals with root resorption< 2mm were categorized as a control group(Group 1; n=90), and resorption >2mm were categorized as case group (Group 2; n=52). Buccal swabs of all patients were taken and DNA could be isolated in 95 out of 142 samples (group 1 {n=58}, group 2 {n=37}) which were then screened for the selected two polymorphic targets to determine the nucleotide status of these targets. Tetra-primer ARMS PCR reactions were carried out using all 4 primers for each polymorphism.Results > rs11800587 was not associated with risk of EARR in any inheritance model. Chi-square test for association of alleles with EARR revealed that rs1143634 was associated with the risk of EARR in an allelic model in such a way that A allele of this SNP increased the risk of EARR 4 folds [OR = 4.375; p=0.016]. However, the adjusted level of significance using the Holm-Bonferroni method for rs1143634 was p<0.010 for A and G comparison rendering the results non-significant.Conclusion > SNP rs1143634 and SNP rs11800587 were not associated with risk of EARR in any inheritance model.

Load-Velocity Profiles Before and After Heated Resistance Exercise.

Sweet, DK, Qiao, J, Rosbrook, P, and Pryor, JL. Load-velocity profiles before and after heated resistance exercise. J Strength Cond Res 38(6): 1019-1024, 2024-This study examined neuromuscular performance using load-velocity (L-V) profiles in men and women before and after resistance exercise (RE) in hot (HOT; 40° C) and temperate (TEMP; 21° C) environments. Sixteen (f = 8, m = 8) resistance-trained individuals completed a single 70-minute whole-body high-volume load (6 exercises, 4 sets of 10 repetitions) RE bout in HOT and TEMP. Before and after RE, rectal temperature (TRE), muscle temperature of the vastus lateralis (TVL) and triceps brachii (TTB), and an L-V profile for the deadlift and bench press were recorded. Thermoregulatory and L-V data were analyzed using separate 2-way repeated measures analysis of variances (ANOVAs; condition [hot, temperate] and time [pre, post]) with significance level set at p ≤ 0.05. Deadlift peak velocity was reduced at 60% 1 repetition maximum (1RM) after RE in HOT but not TEMP. Peak velocity of 40% 1RM bench press was lower in TEMP vs. HOT pre-RE (p < 0.01). Peak velocity was decreased at all loads in the deadlift L-V profile after RE, regardless of condition. Despite elevated TRE (TEMP; 37.58 ± 0.35, HOT; 38.20 ± 0.39° C), TVL (TEMP; 35.24 ± 0.62, HOT; 37.92 ± 0.55° C), and TTB (TEMP; 35.05 ± 0.78, HOT; 38.00 ± 0.16° C) after RE in HOT vs. TEMP (p < 0.01), RE in HOT did not broadly affect L-V profiles. This indicates heated resistance exercise can be performed with high-volume load and high ambient temperature with minimal performance impairment.

Lipoprotein Oxidation, Genetic Expression and Polymorphism of Apo A and B Gene in Patients with Coronary Artery Disease in A Pakistani Punjabi Population

Oxidative alterations of lipoproteins and numerous polymorphism locations in the apolipoprotein A1 (APOA1) and B (APOB) genes have been identified as risk factors for cardiovascular events. The aim of the study was to investigate the gene expression and the role of APOA and B gene polymorphisms in coronary artery disease (CAD) and their relationship with lipid profiles, oxidized High Density Lipoprotein (oxHDL), and oxidized Low Density Lipoprotein (oxLDL) in the Punjabi Pakistani population. A total of 200 subjects were included, of which 135 were diagnosed as having CAD and 65 were not. The lipid profile, oxHDL, and oxLDL were measured through the calorimetric method and ELISA, respectively. Quantitative variables represented by mean ± SD for normally distributed data. Gene expression was done on cDNA through Real-time PCR. Genotyping of APOA1 (rs670, rs5069) and APOB (rs693, rs11279109) were performed by PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism), and gel electrophoresis was used for band visualization. Our findings showed that the oxHDL, oxLDL, APOA, B gene expression and Del genotype of APOB rs11279109 was significantly increased in CAD cases. In addition, significant high levels of oxHDL, oxLDL, serum cholesterol, VLDL, TG, and cholesterol/HDL ratio has been shown to be associated with CAD. APOB (rs11279109) has a significant impact on dyslipidemia and exhibit a higher risk of CAD (OR=3.97) while, APOB (rs693), APOA1 (rs670), (rs5069) possesses a lower risk of CAD in the population. Hence, levels of oxHDL and oxLDL as well as ApoA1 and APOB genotyping could be useful in identifying individuals who are at risk of CAD.

Response of Growth and Yield of Samhong King Curly Mustard Greens (Brassica juncea L.) to Land Tillage and Differences in Mulch Application

Land processing intensively and over an extended period can lead to a decline in cultivated land quality, resulting in suboptimal plant growth. The utilization of mulch is anticipated to enhance soil quality, enabling mustard plants to thrive and yield effectively. This study investigates the most effective type of mulch in conjunction with land tillage to maximize the growth and productivity of Samhong King curly mustard greens. The experiment was conducted at the Mapena Agricultural and Livestock Polytechnic experimental garden from November 2023 to March 2024. A factorial (3x2) experiment was set up in a randomized complete block design with four blocks. The first factor, mulch type, comprised three levels: straw, silver-black, and no mulch. On the other hand, the second factor, land tillage, consisted of two levels: tillage and no-tillage. Observations encompassed growth parameters, harvest variables, and environmental factors. The data underwent statistical analysis using analysis of variance (ANOVA), with Tukey's statistic calculated at a significance level of 5%. The findings revealed that the combination of tillage with silver-black mulch application facilitated superior growth and yield of curly mustard greens compared to the application of straw mulch or no mulch with tillage and no-tillage.

Factors influencing the acceptance of cesarean sections among women of reproductive age in ekiti state, Nigeria

The study examined factors influencing the acceptance of cesarean sections among Women of Reproductive age in Ekiti State. Specifically, the study assessed how socio-demographic and socio-economic factors influenced the acceptance of cesarean sections. A descriptive survey research design was employed for the study. The population for this study consisted of women of reproductive age spread across the three senatorial districts of Ekiti State. The sample for the study was 325 women of reproductive age whose selection was based on multistage sampling procedure. An interviewer administered questionnaire was used to collect data for the study. The reliability of the instrument was determined through Cronbach's Alpha method and a reliability co-efficient of 0.9 was obtained. All data obtained were analyzed using descriptive and inferential statistics. The research questions were analyzed with descriptive statistics using frequency counts, percentage, mean and standard deviation. Hypotheses formulated were tested using linear and multiple regression analysis at 0.05 level of significance. The findings revealed that age, educational status, religious belief, cultural belief and socio-economic status respectively has significant influence on acceptance of cesarean sections among the participants. It was therefore recommended that public health officials should re-orientate women of reproductive age on cesarean sections as an alternative means of child delivery; elderly Primigravida and Multigravida women should be encouraged to undergo cesarean sections delivery if there are indications for it in order to reduce the risk of complications through vaginal delivery method.

Serial neutrophils count as a stratifying tool for early follicular tonsilitis remission

Background/Aim: This study examines the correlation between sequential serum neutrophil levels and the overall improvement status or reduction rate of intravenous antibiotic administration. This study seeks to identify a cost-effective and easily accessible biomarker that can accurately predict the need for hospitalisation in patients with acute tonsillitis who are receiving intravenous broad-spectrum antibiotics. The goal is to determine the patients' suitability for early discontinuation of intravenous antibiotics and discharge. Methods: This study was conducted at the King Hussein Medical Centre in Jordan, focusing on patients with severe acute tonsillitis who did not respond to oral antibiotics. Data was collected from the electronic medical record system (Hakeem) from January 2018 to May 2021. The study classified serial serum neutrophil measurements during the first week of hospital admission into four categories. The levels were compared between the non-penicillin Cohort (Group I) and penicillin Cohort (Group II) using an Independent-T Test. The outcomes of interest included a drop in neutrophil counts exceeding 50%, a decrease in the use of intravenous antibiotics in favor of oral antibiotics, and early eligibility for discharge. The study also examined serial neutrophil counts over the tested days and compared to the outcomes of positive and negative states using receiver operating curve analyses. The optimal cutoff operating point for each ROC curve was determined by selecting the highest Youden's index of each prognosticator day level. The analysis of all results was conducted using SPSS version 20 with a significance level set at p-value &lt;0.05. Results: This study analyzed 1638 adult and elderly patients admitted to KHMC, RMS, Amman, Jordan between January 2018 and May 2021. The average age was 51.88±16.22 years, with patients dependent on intravenous penicillin being slightly older. The distribution of males and females was significant, with males making up 2.55 times the number of females. The odds ratio for positive outcomes was 4.12, with a high rate of poor outcomes in 1318 out of all eligible patients. A total of 994 (60.7%) medical patients were treated with intravenous administration, while 644 (39.3%) surgical patients were scheduled for a tonsillectomy procedure. The risk estimate for patients admitted from medical wards compared to surgical wards was an odds ratio of 0.562. The study also provided sensitivity analysis for the four tested serial neutrophil prognosticators at different day levels. Conclusion: The study supports the use of Somatic Nucleated Cell (SNC) as a reliable measure for evaluating EFR in cases of catarrhal acute tonsillitis. The maximum SNC count in Group one was 11,269 cells per cubic millimeter. Acute streptococcal infection often exhibits an ESR higher than 40, but this may be concealed by other complications. The SNC test has advantages like simplicity, quickness, and cost-effectiveness, but lacks specificity. Monitoring SNC and EFR fluctuations can initiate treatment cessation, preventing relapse and severe complications during recovery.

The relationship between anxiety and postoperative pain after Laparoscopic Sleeve Gastrectomy; A prospective cohort study

Background: Anxiety is an emotional situation marked by apprehension, agitation, tachypnea, tachycardia and hypertension. There has been a recent rise in the amount of patients who have undergone surgery for morbid obesity. The STAI anxiety scale was the primary tool for measuring anxiety levels. Aim: The purpose of this research was to evaluate the levels of anxiety in patients with morbid obesity both before and after surgery and to identify the factors that contribute to this anxiety. Methods: This is a prospective cohort study that uses quantitive descriptive methodology. The study included 129 patients planned for laparoscopic sleeve gastrectomy. The STAI anxiety scale was used to assess anxiety levels both before and after surgery. The patients' pain levels were assessed using VAS during the postoperative period. Results: In comparison of genders, female patients' pre-op anxiety levels were statistically significantly higher (p= 0.001). The anxiety levels differed significantly between preoperative and postoperative patients. Even it has not reached a significant level, the elderly group had lower pre-op anxiety scores than the others, but higher post-op anxiety scores. Educational level didn’t effect anxiety scores. The correlation between patients' anxiety levels and VAS pain levels was found to be statistically significant (p=0.001). Conclusions: Anxiety plays a significant role in influencing postoperative pain and the subsequent analgesic needs after sleeve gastrectomy procedures. Postoperative pain is the primary cause of perioperative anxiety. Females exhibit higher preoperative anxiety levels than males.

A healthy habitual score for dietary intake is associated with primary dysmenorrhea among adolescent school girls

Background: Primary dysmenorrhea is one of the most common gynecological complaints among adolescent and young females in their reproductive age that affects their daily activities and social life. Nutritional habits are considered as risk factor for primary dysmenorrhea. ‘Thus the aim of our study was to assess the relation between healthy habits score for dietary intake and prevalence of primary dysmenorrhea. Methods: The present study was conducted on 432 adolescent school girls (218 girls with nil to mild dysmenorrhea and 214 girls with moderate to severe dysmenorrhea). Healthy habitual scores (HHS) was calculated from 5 modifiable dietary intake habits considering high risk habit as ‘0’ and low risk habit as ‘1’ giving a composite score ranging from 0 to 5. We classified the healthy life style score into three category: 0-2 as low; 3 as medium and 4-5 as high. Correlation between HHS and its components with incident of primary dysmenorrhea were evaluated. HHS and risk of primary dysmenorrhea were evaluated using logistic regression analysis. The significance level of the all the tests were considered at a level of 0.05. Results: Significant correlation was obtained between incident of primary dysmenorrhea and all tested habits. Magnitude of correlation was higher for HHS than individual habit. Among tested habitual factors sugar intake, skipping breakfast and frequency of junk food intake was positively correlated where as negative correlation was obtained between primary dysmenorrhea and dietary intake of vit-E and calcium. Considering low HHS as reference group odd ratio significantly low in medium and high HHS groups. Thus risk of primary dysmenorrhea was more among adolescent girls those led unhealthy dietary habits like take more sugar, frequently take junk foods and skipping breakfast and take vit-E and calcium below recommended amount. Conclusion: Avoiding of Junk food, skipping breakfast and intaking of vit-E and calcium as per recommended amount and restricting sugar intake is recommended as a healthy dietary habit to minimize the risk of primary dysmenorrhea.

Characterization of posterior circulation blood perfusion in patients with different degrees of basilar artery tortuosity.

The morphology of basilar artery (BA) may affect posterior circulation blood perfusion. We aimed to investigate whether different degrees of BA tortuosity could lead to the alterations of posterior circulation perfusion. We collected 138 subjects with different BA tortuosity scores, including 32 cases of score 0, 45 cases of score 1, 43 cases of score 2, and 18 cases of score 3. A higher score represented a higher degree of BA tortuosity. Ordered logistic regression analysis was performed to investigate the risk factors for BA tortuosity. We quantitatively measured the cerebral blood flow (CBF) in eight posterior circulation brain regions using arterial spin labeling. SPSS 25.0 was used for statistical analysis. The correlation between the CBF and BA tortuosity was corrected by the Bonferroni method. The significance level was set at 0.006 (0.05/8). Hypertension (HR: 2.39; 95%CI: 1.23-4.71; P = 0.01) and vertebral artery dominance (HR: 2.38; 95%CI: 1.10-4.67; P = 0.03) were risk factors for BA tortuosity. CBF in occipital gray matter (R = -0.383, P < 0.001), occipital white matter (R = -0.377, P < 0.001), temporal gray matter (R = -0.292, P = 0.001), temporal white matter (R = -0.297, P < 0.001), and cerebellum (R = -0.328, P < 0.001) were negatively correlated with BA tortuosity degree. No significant correlation was found between the BA tortuosity degree and CBF in hippocampus (R = -0.208, P = 0.014), thalamus (R = -0.001, P = 0.988) and brainstem (R = -0.204, P = 0.016). BA tortuosity could affect posterior circulation blood perfusion. CBF was negatively correlated with BA tortuosity degree. The morphology of BA may serve as a biomarker for posterior circulation and the severity of posterior circulation ischemia.

The influence of banking liquidity risk on profitability: The moderating role of capital adequacy ratio

The decline in bank liquidity due to slowing economic growth in Indonesia has decreased bank profitability. COVID-19 and the increase in the number of non-performing loans increased the level of bank liquidity risk and decreased capital. Hence, the purpose of this study is to analyze the influence of banking liquidity risk on profitability in the Indonesian banking sector and to examine the role of capital adequacy ratio as a moderating variable. The method section explains panel data analysis using the random-effect model in analyzing the influence of liquidity risk on profitability and the role of capital adequacy ratio as a moderating variable. The results of the analysis show that liquidity risk has a significant positive influence on profitability at the 1% significance level. Moreover, the t-statistic value for capital adequacy ratio as a moderating variable is 2.59 at a 1% significance level. This result shows that the capital adequacy ratio can moderate the relationship between liquidity risk and profitability. Furthermore, the robustness test results show that the deposit risk ratio is a good indicator for estimating liquidity risk. In addition, this study is useful for the banking sector in managing its capital adequacy ratio and as a reference for the government in setting policies related to banking capital.

Effect of glazing and thermocycling on the fracture toughness and hardness of a New fully crystallized aluminosilicate CAD/CAM ceramic material

BackgroundThe mechanical properties of fully crystallized lithium aluminosilicate ceramics may be influenced by intraoral temperature variations and postmilling surface treatment. The purpose of this study is to explore the interplay among glazing, thermocycling, and the mechanical characteristics (namely, fracture toughness and hardness) of fully crystallized lithium aluminosilicate ceramics.MethodsBending bars (n = 40) cut from LisiCAD blocks (GC, Japan) were randomly assigned to glazed or unglazed groups (n = 20) and subjected to the single edge v-notch beam method to create notches. A glazing firing cycle was applied to the glazed group, while the unglazed group was not subjected to glazing. Half of the specimens (n = 10) from both groups underwent thermocycling before fracture toughness testing. The fracture toughness (KIC) was evaluated at 23 ± 1 °C using a universal testing machine configured for three-point bending, and the crack length was measured via light microscopy. Seven specimens per group were selected for the hardness test. Hardness was assessed using a Vickers microhardness tester with a 1 kg load for 20 s, and each specimen underwent five indentations following ISO 14705:2016. The Shapiro–Wilk and Kolmogorov-Smirnov tests were used to evaluate the normality of the data and a two-way ANOVA was utilized for statistical analysis. The significance level was set at (α = 0.05).ResultsRegardless of the thermocycling conditions, the glazed specimens exhibited significantly greater fracture toughness than did their unglazed counterparts (P < 0.001). Thermocycling had no significant impact on the fracture toughness of either the glazed or unglazed specimens. Furthermore, statistical analysis revealed no significant effects on hardness with thermocycling in either group, and glazing alone did not substantially affect hardness.ConclusionsThe impact of glazing on the fracture toughness of LiSiCAD restorations is noteworthy, but it has no significant influence on their hardness. Furthermore, within the parameters of this study, thermocycling was found to exert negligible effects on both fracture toughness and hardness.
