Published: January 2025

This study contains research on the analysis of the distribution of vowel phonemes in the reading material of grade 1 elementary school textbooks. The research is based on the rampant language errors in the field of pronunciation. These errors are caused by ignorance of good and correct pronunciation. So this research aims to introduce the pronunciation through the distribution of vowel phonemes in a word in the smallest community environment, namely schools. The phoneme distribution analysis in this study uses the theory of phonetic transcription, vowel classification, and distribution of Indonesian phonemes. The method used is descriptive qualitative. The results of the analysis show that the reading material in the textbook contains ten phonological symbols in the form of [a, i, ?, u, U, e, ?, ?, o, ?]. The ten symbols are pronounced in different ways based on the sound organs they use. The vowel phoneme that always appears in the reading material is the sound [a] which dominates the appearance at the beginning of the word, the middle of the word, and the end of the word.

Authors: Hamad Shehab Ahmed , Xailani Kocher Kareem 
Published: January 2025

Dental implants are widely recognized as a reliable solution for tooth replacement, with consistently high success rates. However, the pursuit of improved aesthetic outcomes and patient satisfaction has driven the advancement of techniques to enhance soft tissue stability around implants. This study investigated the effect of immediate implant placement combined with bone grafts and healing caps on soft tissue thickness and height. A prospective clinical study was conducted involving ten patients undergoing immediate tooth extraction and implant placement. A total of 18 implants were placed, with bone grafts applied around the implants and healing caps utilized. Gingival thickness and height were measured before tooth extraction and six months post-implantation using injection needles and transgingival probing methods. The results revealed significant increases in gingival dimensions after six months. The mean gingival height improved from 1.3 mm pre-extraction to 3.9 mm post-implantation, while the mean gingival thickness increased from 1.9 mm to 4.2 mm. The findings demonstrated stable gingival tissue and favorable aesthetic outcomes, underscoring the efficacy of immediate implant placement combined with bone grafts and healing caps. This approach significantly enhances soft tissue stability and aesthetics, providing a promising method for improving long-term implant success and patient satisfaction.

Published: January 2025

Background: Diabetes Mellitus is among the most frequent enduring metabolic disorders in the broad populace and leads to many complications, including tooth decay. In this study, the relationship between HbA1c level and dental caries has been investigated to be a step towards increasing awareness and improving the health status and quality of life of diabetics. Materials and Methods: This cross-sectional study was carried out on 20 type 2 diabetic who referred to dental clinic of shiraz university of medical sciences between 2022 and 2023 and were separated into two categories of managed diabetes (HbA1c under 7%) and uncontrolled (HbA1c above 7%). The desired data were obtained through a questionnaire containing demographic information, clinical examination (DMFT (Decayed, Missing, Filled Teeth) index), oral hygiene, and carbohydrate consumption. Results: The average DMFT index is greater in individuals with unmanaged diabetes compared to those with Controlled Diabetes, though not statistically significant (P=0.137). However, as BMI increases, so does the DMFT index (P=0.035). There is no notable correlation between HbA1c levels and dental caries (P=0.2). Oral hygiene practices did not significantly affect the DMFT index (P=0.943). Carbohydrate intake per day did not impact the DMFT (P=0.34). Higher education levels were associated with a decrease in DMFT, though not statistically significant (P=0.172). Conclusion: Considering the higher rate of dental caries in individuals with uncontrolled diabetes, it is necessary to inform these patients about more oral and dental hygiene and blood sugar control.
Impact of distortions in UAV images on quality and accuracy of object localization
Authors: Tsekhmystro Rostyslav , Rubel Oleksii , Prysiazhniuk Oleksandr , Lukin Vladimir 
Published: January 2025

The localization and classification of objects of different types in images is an important and actively researched topic because the designed methods and tools are exploited in a wide variety of fields, including remote sensing, security systems, and medical diagnostics. Imaging systems installed on-board unmanned aerial vehicles (UAVs) and drones have become popular recently, and they are potentially beneficial for numerous applications like mine detection, traffic control, and crowd control. Images acquired by such systems may suffer from low quality because of the use of rather cheap cameras and the necessity to transfer obtained data via communication lines with limited bandwidth, employing lossy compression. These factors can influence the quality and accuracy of object localization, which is typically negatively performed by trained neural networks. However, the intensity of the noise and distortions that can be considered acceptable, i.e. such that they do not lead to radical reduction of the performance characteristics are unclear. Given this, it is reasonable to investigate the impact of these effects on the quality of object localization and classification using a reliable data size and various noise/distortion intensities. Therefore, the research subject of this paper is the performance of object localization and classification methods for color images acquired by UAV-installed sensors. The primary focus is on the dependence of localization and classification metrics on the noise intensity, where the simulated noise mimics not only noise but also distortions due to lossy compression by modern coders. The aim of this work is to obtain adequate statistics and analyze them to build dependencies of the metrics on the intensity of distortions. The objective is to obtain conditions for which the effects of noise and distortions can be considered negligible or acceptable in practice. The second objective is to analyze the sensitivity of several modern neural network models to noise/distortions. The result is a statistical assessment of the dependence of model performance on input data quality. The conclusions are based on the statistics characterizing the model performance for the noise/distortion intensity interval. The conclusions allow the selection of the best (most robust) neural networks and the establishment of appropriate performance conditions.

IntroductionA continuing challenge for malaria control is the ability of Plasmodium falciparum to develop resistance to antimalarial drugs. Members within the Plasmodium transcription factor family AP2 regulate the growth and development of the parasite, and are also thought to be involved in unclear aspects of drug resistance. Here we screened for single nucleotide polymorphisms (SNPs) within the AP2 family and identified 6 non-synonymous mutations within AP2-06B (PF3D7_0613800), with allele frequencies greater than 0.05. One mutation, K3124R, was located in a PfAP2-06B AP2 domain.MethodsTo investigate transcriptional regulation by PfAP2-06B, ChIP-seq assays were performed on 3D7/PfAP2-06B-GFP schizonts using antibodies against GFP. The DNA sequences of the artemisinin-resistant CWX and the quinoline-resistant strains PfDd2 and Pf7G8 were analyzed for the genetic diversity of AP2-06B, compared with the Pf3D7 strain as a reference sequence. To determine whether AP2-06B can alter the expression of pfk13 and pfcrt, as well as cause artemisinin and quinoline resistance in Plasmodium, we generated both a K3124R mutation and conditional knockdown of AP2-06B in Pf3D7 using CRISPR/Cas9-mediated genome editing.ResultsChIP-Seq analysis showed that AP2-06B can bind to the loci of the Plasmodium genes pfk13 and pfcrt. The AP2-06B K3124R mutation was also found in the artemisinin-resistant parasite strain CWX and the chloroquine-resistant strains Dd2 and 7G8. Contrary to expectation, Pf3D7 Plasmodium lines modified by either K3124R mutation of AP2-06B or conditional knockdown of AP2-06B did not have altered sensitivity to artemisinin or quinolines by modulating pfk13 or pfcrt expression.DiscussionAP2-06B was predicted to be associated with artemisinin and quinoline resistance, but no change in resistance was observed after mutation or conditional knockdown. Given the multigenic nature of resistance, it might be difficult to recreate a resistance phenotype. In conclusion, whether AP2-06B regulates the development of artemisinin or quinoline resistance remains to be studied.

Published: January 2025

BackgroundThis study examines the relationship between Hb, RDW and their association and both short-term and long-term mortality in patients with acute aortic dissection (AAD), aiming to establish combined effect between Hb and RDW as a potential prognostic biomarker for AAD outcomes.MethodsWe extracted clinical data from the Medical Information Mart for Intensive Care (MIMIC) databases for this analysis. Using adjusted Cox regression and Kaplan-Meier survival curve analyses, we assessed the relationship between Hb, RDW and their association at admission and mortality at multiple post-discharge intervals (30 days, 90 days, 1 year, and 5 years) among patients with AAD. Additionally, subgroup analyses and receiver operating characteristic (ROC) curve analyses were conducted to evaluate the predictive accuracy of Hb, RDW and their association for mortality in this patient population.ResultsHigh RDW combined with low Hb (RDW ≥ 13.60 and Hb &lt; 7.9) significantly predicted increased mortality at 30 days, 90 days, 1 year, and 5 years post-diagnosis, with hazard ratios (HRs) as follows: 4.33 (95% CI: 1.82–10.33, P &lt; 0.001), 4.48 (95% CI: 2.06–9.77, P &lt; 0.001), 3.38 (95% CI: 1.70–6.70, P &lt; 0.001), and 3.07 (95% CI: 1.66–5.66, P &lt; 0.001), respectively.ConclusionHb and RDW are both abnormal (Hb with low level, RDW with high level) is positively correlated with 30 days, 90 days, 1 year, and 5 years mortality risk in patients with AAD. This suggests that combined effect between Hb and RDW is a significant predictor of short-term to long-term mortality risk in this patient population, highlighting its potential utility as a prognostic marker in clinical settings.

IntroductionVericiguat, an oral stimulator of soluble guanylate cyclase, reduces cardiovascular mortality and hospitalisations in patients with heart failure (HF) and reduced ejection fraction, as demonstrated in the VICTORIA trial. This study assessed the real-world use of vericiguat.Material and methodsThis cross-sectional, prospective and multicenter registry (VERISEC) included 776 patients from 43 centres in Spain between December 2022 and October 2023. Of these patients, 79.6% were male, with a mean age of 72.4 (SD:8.7) years. Patients in VERISEC were older and had more comorbidities (diabetes, advanced chronic kidney disease) compared to VICTORIA, with 20% having an estimated glomerular filtration rate below 30 ml/min. They also had higher natriuretic peptide levels [NT-proBNP: 3551 (IQR: 1,675.9, 7,054.0)] pg/ml. Most patients (79.8%) started vericiguat after HF decompensation within the previous three months, with high use of loop diuretics (with an average dose of 65 mg/day) and implanted devices (50%). Sixty percent of patients were on quadruple therapy, with a higher use of sodium-glucose co-transporter 2 inhibitors compared to the VICTORIA trial. Despite the more severe disease in the VERISEC cohort, the implementation of guideline-directed medical therapy was greater than in VICTORIA, although vericiguat was initiated at lower blood pressure levels.ConclusionsPatients in the VERISEC registry had more severe illness and higher comorbidities compared to those in the VICTORIA, despite receiving optimised treatments. Further research is needed to identify which patients may benefit the most from vericiguat treatment.
