Abstrak: Penelitian ini berfokus pada rendahnya minat siswa di salah satu sekolah menengah pertama di Kota Malang dalam mempelajari sains, terutama kesulitan dalam memahami istilah-istilah ilmiah dalam materi sains yang diberikan. Keterbatasan sumber belajar dan kurangnya perubahan dalam strategi pengajaran diidentifikasi sebagai penyebab rendahnya minat tersebut. Minimnya penggunaan media pembelajaran oleh guru yang hanya monoton menggunakan ppt dan buku teks membuat pembelajaran menjadi kurang variatif dan membuat siswa kurang tertarik untuk mengikuti pembelajaran. Penelitian ini mengevaluasi dampak penggunaan media pembelajaran berbasis web pada materi perkembangan hewan dan tumbuhan terhadap hasil belajar siswa kelas IX. Dengan menggunakan metode kuantitatif dan uji ANOVA, media web yang menyajikan konten melalui video, teks, dan gambar dibandingkan dengan PPT dan buku pelajaran konvensional di dua kelas. Hasil analisis data menunjukkan adanya perbedaan yang signifikan antara kedua kelompok (F hitung = 7,691, signifikansi = 0,008). Respons positif siswa terhadap media web menegaskan keefektifannya dalam meningkatkan minat dan pemahaman sainsAbstract: This research focuses on the low interest of students in one of the junior high schools in Malang City in learning science, especially the difficulty in understanding scientific terms in the given science material. Limited learning resources and lack of change in teaching strategies were identified as the causes of low interest. The lack of use of teaching media by teachers, who only monotonously use PPTs and textbooks, makes learning less varied and makes students less interested in participating in learning. This study evaluates the impact of web-based learning media on animal and plant development material on the learning outcomes of Grade IX students. Using quantitative methods and the ANOVA test, web media presenting content through video, text, and images were compared with PPT and conventional textbooks in two classes. The results of the data analysis showed a significant difference between the two groups (F count = 7.691, significance = 0.008). The students' positive response to the web media confirmed its effectiveness in increasing interest and understanding of science.

Translation is a process of transforming information from source representation to target representation. The translation process is described in four activities, such as unpacking the source, preliminary coordination, constructing the target, and determining equivalence. This study aims to analyze and describe the translation process of mathematical representations from verbal to symbolic in UM Mathematics S1 students in solving statistics on variance and standard deviation material. The instruments used were translation test questions and interview guidelines. Data analysis focused on four translation activities which were then categorized (high, medium, low). The results of the research percentage show that 78.58 percent of students experience difficulties in translating representations from verbal to symbolic in statistical problems. This is because students make mistakes in interpretation and implementation. While 21.42 percent of students succeeded in translating representations in solving the variance and standard deviation problems that have been presented. In terms of categorization, 21.42 percent of students belong to the high category, 39.29 percent of students belong to the medium category, and 39.29 percent of students belong to the low category. At this stage, the researcher obtained 28 student subjects for further analysis through 4 (four) stages of translation.

Relevance. Oenothera tetragona is an ornamental plant used in folk medicine. Until now, studies of the biological characteristics of the Oenothera tetragona have not been carried out on the territory of the NonChernozem zone of the Russian Federation.The purpose of the work is the introduction and biological study of the Oenothera tetragona in the NonChernozem zone of Russia in the conditions of the Moscow region.Methodology. The experiment was based on two-month-old seedlings according to a 60x30 cm pattern. Phenological observations and biometric measurements (during the mass flowering phase) were carried out according to the methods adopted at VILAR (All-Russian scientific research Institute of medicinal and aromatic plants). Experimental data were processed according to B.A. Dospehov. Weather conditions were checked on the Weather and Climate website. Microspecimens were prepared according to methods for light microscopy.Results. In the conditions of the Moscow region the period from the beginning of the growing season to mass fruiting in Oenothera tetragona Roth. averages about 110-115 days. The plant is well adapted: it goes through the entire seasonal cycle of growth and development. The population includes Oenothera tetragona Roth. includes many variable biotypes, which indicates the possibility of targeted selection of forms with useful traits. The main assessment of breeding material can be carried out, starting from the second year of plant life, based on a set of interrelated quantitative traits (height, number of generative shoots, etc.). Some anatomical features of the epidermis of the Oenothera tetragona leaf have been studied for the first time; the number of covering trichomes and the number of stomata per 1 mm2 were determined. As a result of microscopic examination of the epidermis of leaf plates of O. tetragona Roth.: the presence of three groups was revealed, which differed in microscopic characteristics (shape and number of stomata, pubescence) in the absence of a noticeable correlation with the main phenotypic characteristics.

Published: July 2024

Background:
This study aimed to establish an equation for calculating cup ante-inclination (AI) from radiographic cup inclination and anteversion, to validate this equation in a total hip arthroplasty (THA) cohort, and to test whether achieving previously described radiographic cup inclination and anteversion targets would also satisfy sagittal cup AI targets.

Methods:
A mathematical equation linking cup AI, radiographic inclination (RI), and anteversion (RA) was determined: tan(AI) = tan(RA)/cos(RI). Supine and standing anteroposterior and lateral radiographs of 440 consecutive THAs were assessed to measure cup RI and RA and spinopelvic parameters, including cup AI, using a validated software tool. Whether orientation within previously defined RI and RA targets was associated with achieving the AI target and satisfying the sagittal component orientation (combined sagittal index, 205° to 245°) was tested.

Results:
The cups in the THA cohort had a measured mean inclination (and standard deviation) of 43° ± 7°, anteversion of 26° ± 9°, and AI of 34° ± 10°. The calculated cup AI was 34° ± 12°. A strong correlation existed between measured and calculated AI (r = 0.75; p < 0.001), with a mean error of 0° ± 8°. The inclination and anteversion targets were both satisfied in 194 (44.1%) to 330 (75.0%) of the cases, depending on the safe zone targets that were used, and 311 cases (70.7%) satisfied the AI target. Only 125 (28.4%) to 233 (53.0%) of the cases satisfied the AI target as well as the inclination and anteversion targets. Satisfying inclination and anteversion targets was not associated with increased chances of satisfying the AI target.

Conclusions:
Achieving optimal cup inclination and anteversion does not ensure optimal orientation in the sagittal plane. The equation and nomograms provided can be used to determine and visualize how the 2 planes used for evaluating the cup orientation and the pertinent angles relate, potentially aiding in preoperative planning.

Abstract

Schizophrenia spectrum disorder (SSD) is one of the top causes of disease burden; similar to other psychiatric disorders, SSD lacks widely applicable and objective biomarkers. This study aimed to introduce a novel resting-state functional connectivity (rs-FC) magnetic resonance imaging (MRI) biomarker for diagnosing SSD. It was developed using customised machine learning on an anterogradely and retrogradely harmonised dataset from multiple sites, including 617 healthy controls and 116 patients with SSD. Unlike previous rs-FC MRI biomarkers, this new biomarker demonstrated a notable accuracy rate of 77.3% in an independent validation cohort, including 404 healthy controls and 198 patients with SSD from seven different sites, effectively mitigating across-scan variability. Importantly, our biomarker specifically identified SSD, differentiating it from other psychiatric disorders. Our analysis identified 47 important FCs significant in SSD classification, several of which are involved in SSD pathophysiology. Beyond their potential as trait markers, we explored the utility of these FCs as both state and staging markers. First, based on aggregated FCs, we built prediction models for clinical scales of trait and/or state. Thus, we successfully predicted delusional inventory scores (r = 0.331,P = 0.0177), but not the overall symptom severity (r = 0.128,P = 0.178). Second, through comprehensive analysis, we uncovered associations between individual FCs and symptom scale scores or disease stages, presenting promising candidate FCs for state or staging markers. This study underscores the potential of rs-FC as a clinically applicable neural phenotype marker for SSD and provides actionable targets to neuromodulation therapies.

Abstract

Background: Polycystic Ovary Syndrome (PCOS) has emerged as a widespread endocrine health challenge for women in the childbearing phase by imposing an adverse influence on fertility. Unfortunately, the existing treatment-strategies are inadequate and largely focused on symptom-based relief. Therefore, the demand for safer herbal alternatives is more pressing than ever.Asparagus racemosus Willd. has a longstanding history as a traditional herb for addressing diverse hormonal and fertility complications. The present study explored the in-depth mechanism by which A. racemosus ethanolic extract (ARE) ameliorates PCOS in female adult rats.
Methods: ARE at different doses (100, 150, 250 mg/kg-bw) were concurrently supplemented in the letrozole-induced PCOS group (1 mg/kg-bw) for a continuous period of 21 days. LC/ESI-MS was employed for determination of active phytotherapeutics within the ARE. Biochemical assay, ELISA, native PAGE expression, Real-time PCR, immunostaining and histological study were implemented for the experimental analysis.
Results: ARE regularized the disrupted estrous pattern, improved metabolic status and balanced endocrine activity by reducing excess androgen production. ARE restored intraovarian antioxidant enzyme expression and markedly reduced the mRNA expression of inflammatory (NFkB/TNFα) and proapoptotic markers (Bax/P53) along with elevated expression of anti-apoptotic factor (BCL2). The downregulation of androgen receptor (AR) in ovarian tissue accompanied by a decreased in the angiogenic factor VEGF-B were also observed. ARE improved gonadal weights and histomorphology by limiting the formation of cystic follicles and promoting folliculogenesis. The presence of essential secondary metabolites, specifically steroidal sapogenin, isoflavones and polyphenols, is primarily responsible for these advantageous effects.
Conclusion: The observed findings suggested that A. racemosus could be a highly effective safer alternative therapeutic intervention for managing the complexities of PCOS.

Abstract

Random geo-referenced soil surface (0–15 cm) samples were used to study the geographical variability of soil properties and plant-accessible silicon (Si) in rice growing soils of three districts of Jammu plains. The represent study was conducted descriptive statistics along with graphs for spatial distribution of soil data. The region had an interquartile range (IQR) of sand (%), silt (%), clay (%), pH, electrical conductivity (dSm− 1), soil organic carbon (g kg− 1), and cation exchange capacity (cmol (p+) kg− 1), 8.14, 5.80, 6.76, 1.10, 0.11, 2.70 and 1.88, respectively. The interquartile range (IQR) of available nitrogen (kg ha− 1), phosphorus (kg ha− 1), potassium (kg ha− 1), and sulfur (ppm) was noted to be 94.45, 16.93, 74.35, and 8.98, respectively. Positive skewness distribution was found in all physico-chemical properties, except sand content. Positive kurtosis distribution was found in all available nutrients except available nitrogen. Out of 10, 4 principal components exhibited greater than 1.00 eigen value and explained 89.00% cumulative variability among the parameters studied. The Dim 1 displayed 55.9% while Dim 2, Dim 3 and Dim 4 exhibited 16.9%, 10.3% and 5.9% variability, respectively amongthe parameters under study. This study will be helpful in identifying the variability contributing parameter and selection of suitable parameters in Jammu plains.

Abstract

Background: One of the common challenges encountered by the Obstetrics and Gynecology (ObGyn) specialists is medico-legal issues including litigations for medical malpractice, lawsuits for medical errors and others. The magnitude of the challenges, perceptions and concerns are not well known. This study looked at these factors.
Methods: a cross-sectional assessment of current encounters, experiences and perceptions of practicing ObGyn physicians who attended the Ethiopian Society of Obstetricians and Gynecologists conference in February 2016. A self-administered semi-structured questionnaire was used to collect the data. Descriptive statistics were done to determine the magnitude of the different issues in relation to medico-legal issues.
Results: A total of 112 obstetricians and gynecologists (OBGYNs) were interviewed, median age of the participants was 40 years and only 8.9% were women. Close to half of them worked in Addis Ababa and the same proportion worked in the public sector.
Nearly a third (34.8%) admitted making at least one error, 21.4% have been accused of malpractice, 21.4% were questioned by police/attorney and 6.3% were imprisoned. 83.3% of those who were questioned were declared free. 83% claimed to know someone who was accused of malpractice unfairly. Only 55.4% were aware of the role of the federal ethics committee.
Conclusions: Many ObGyns are neither knowledgeable nor ready for management of medical error. There is a huge concern about the fairness of the treatment they receive for medical error lawsuits. Fear of litigation is enormous. Improving awareness about medical errors and their management paired with creating clarity on the roles of the federal ethics committee is highly needed. Bridging the gap between the judiciary system and the ObGyn society and addressing the disparity between the perceived susceptibility and the reality are crucial.

Published: July 2024

Abstract

Objectives: The primary aim of this investigation was to validate a method for generating 3D replicas through virtual segmentation, utilizing artificial intelligence (AI) or manual-driven methods, assessing accuracy in terms of volumetric and linear discrepancies. The secondary aims were the assessment of time efficiency with both segmentation methods and the effect of post-processing 3D replicas.
Methods: Thirty teeth were scanned through Cone Beam Computed Tomography (CBCT), capturing the region of interest from human subjects. DICOM files underwent segmentation through both AI and manual-driven methods. Replicas were fabricated with a stereolithography 3D printer. After surface scanning of pre-processed replicas and extracted teeth, STL files were superimposed to evaluate linear and volumetric differences using the extracted teeth as the reference. Post-processed replicas were scanned to assess the effect of post-processing on linear and volumetric changes.
Results: AI-driven segmentation resulted in statistically significant mean linear and volumetric differences of -0.709mm and -4.70%, respectively. Manual segmentation showed no statistically significant differences in mean linear (-0.463mm) and volumetric (-1.20%) measures. Comparing manual and AI-driven segmentations, showed that AI-driven segmentation displayed mean linear and volumetric differences of -0.329mm and -2.23%, respectively. Additionally, AI segmentation reduced mean time by 21.8 minutes. When comparing post-processed to pre-processed replicas, there was a volumetric reduction of -4.53% and a mean linear difference of -0.151mm.
Conclusion: Both segmentation methods achieved acceptable accuracy, with manual segmentation slightly more accurate and AI-driven segmentation more time-efficient. Continuous improvement in AI offers the potential for increased accuracy, efficiency, and broader application in the future.
Clinical Significance: Tooth replica generation in the context of tooth autotransplantation therapy may contribute to enhanced success and survival rates. Accurate CBCT-based virtual segmentation and 3D printing technologies are particularly important in the fabrication of 3D replicas. Therefore, it is crucial to assess the accuracy of available techniques and alternatives to demonstrate their reliability and accuracy in the fabrication of tooth replicas.

Authors: Cayubit Ryan Francis O. 
Published: July 2024

Abstract

Despite the declaration of the end of the global health emergency related to COVID-19, the disease remains a significant concern worldwide. However, little is known about how COVID-19 anxiety influences the presence and search for meaning, optimism-pessimism, and academic motivation of university students. This research addresses this gap by determining whether COVID-19 anxiety is a significant predictor of meaning in life, life orientation, and academic motivation. A cross-sectional predictive study was conducted involving 557 samples and the results showed that COVID-19 anxiety negatively impacted amotivation, presence of meaning and life orientation. On the other hand, result also showed that searching for meaning was positively influenced by COVID-19 anxiety. These key findings contribute to the existing body of knowledge on how COVID-19 anxiety affected the general well-being of university students.
