    High-quality clinical photography is essential in orthodontics, playing a crucial role in diagnosis, treatment planning, patient education, and professional communication. However, capturing consistently clear and detailed orthodontic photographs can be challenging, particularly without knowledge of standardized techniques and equipment. This article provides a comprehensive guide on the key elements of effective orthodontic photography, including camera settings, positioning, and lighting. Illustrating each step in the process aims to equip orthodontists with the skills needed to achieve high-quality, reproducible clinical photos that enhance the quality of patient care and support clinical documentation.

    A carotid-cavernous fistula (CCF) involves an abnormal communication between the carotid artery and the cavernous sinus. For indirect CCF, it usually occurs in post-menopausal women. Contralateral symptoms for indirect CCF are rare. We report a 79-year-old lady with underlying hypertension and dyslipidemia, who had a complex indirect CCF from the right internal and right external carotid artery, draining into the left ophthalmic vein and giving rise to left ocular manifestation. Endovascular embolization was attempted but was unsuccessful. The patient subsequently developed a stroke one day post-procedure, with a favorable recovery of function.

    Background Calcific uremic arteriolopathy (CUA) is a rare but debilitating disease affecting patients with kidney disease. Reported risk factors of CUA in the literature include female sex, obesity, diabetes mellitus, and vitamin K antagonists' (VKAs) usage. CUA prevalence in Malaysia is unknown and has not been reported before. Methods A multicenter observational study was conducted in 13 centers all over Malaysia to study the clinical characteristics, treatment, and outcomes of CUA. The data of patients confirmed with CUA between January 1, 2016, and December 31, 2021, was collected from medical records by each center's nephrologists. Results Out of 33 confirmed CUA cases, 69.7% were females, and 66.7% were Malay with a mean age of 47.33 ± 13.80 years old. The mean BMI was 25.66 ± 9.77 kg/m2, and 18.2% were classified as obese (BMI > 30). Two-thirds of the patients were on hemodialysis (HD), and the mean dialysis vintage was 6.2 ± 4.11 years. A majority (87.9%) have hypertension, 33.3% are diabetic, and 27.3% have coronary artery disease. Only 15.2% of the patients were on warfarin at the time of diagnosis. A total of 78.8% of patients were taking calcium-based phosphate binders during diagnosis. Investigation results showed calcium, 2.44 ± 0.29 mmol/L; phosphate, 2.18 ± 0.67 mmol/L; CaXPO4 = 5.41 ± 1.90; and parathyroid hormone, 181.14 ± 153.23 pmol/L. About half (54.5%) had skin biopsy confirmation done. Distribution of lesions was 57.6% peripheral and 30.3% central. For treatment of CUA, there were 57.6% usage of non-calcium-based phosphate binders, 48.5% cinacalcet, 30.3% sodium thiosulphate, and 33.3% had parathyroidectomy. Half (54.5%) of our CUA patients died within three months from diagnosis. The mean time from diagnosis to mortality was 4.12 ± 5.59 months. A majority (45.5%) died from septicemia caused by infections. Interestingly, there were a few rare presentations of CUA such as pulmonary calciphylaxis, heart and lung calcifications, liver and spleen calcifications, and genital lesions. One patient had resistant CUA and was given a trial of lipid apheresis for 10 sessions. Conclusion This is the first and largest multicenter study looking into the characteristics, treatment, and outcome of CUA in Malaysia. Majority of patients in Malaysia undergo HD as kidney replacement therapy; hence, our results correlate with this. The incidence of CUA was estimated to be 6.6 per 10,000 dialysis patients in this study and the mortality rate is very high. This is consistent with worldwide data which reported mortality as high as 60%.

    Background  In the presence of distal femoral condyle bone loss, estimation and restoration of the joint line (JL) position can be guided by extraarticular bony landmarks with the aid of mathematical formulas that rely on the innate correlations between periarticular measurements. To prevent JL elevation, the formula should incorporate the thickness of distal femoral articular cartilage. The aim of this study was to derive a formula to estimate native JL position. Methods One hundred and fifty knee magnetic resonance imaging (MRI) studies belonging to 150 patients were chosen from a database of scans. Multiple periarticular measurements were taken. Based on the strongest correlation between measurements, linear regression analysis was used to derive a regression equation to estimate the JL position. This formula was then tested to determine its accuracy and reliability in estimating the JL. Results  Using the Pearson correlation test, the strongest correlation was identified to be between adductor tubercle to joint line distance (ATJL) and transepicondylar width (TEW) with r = 0.723, p

    Dystonia is one of the most prevalent movement disorders, characterized by significant clinical and etiological heterogeneity. Despite considerable heritability (∼25%) and the identification of several disease-linked genes, the etiology in most patients remains elusive. Moreover, understanding the correlations between clinical manifestation and genetic variants has become increasingly complex. To comprehensively unravel dystonia's genetic spectrum, we performed exome sequencing on 1,924 dystonia patients [40.3% male, 92.9% White, 93.2% isolated dystonia, median age at onset (AAO) 33 years], including 1,895 index patients, who were previously genetically unsolved. The sample was mainly based on two dystonia registries (DysTract and the Dystonia Coalition). Further, 72 additional patients of Asian ethnicity, mainly from Malaysia, were also included. We prioritized patients with negative genetic prescreening, early AAO, positive family history, and multisite involvement of dystonia. Rare variants in genes previously linked to dystonia ( n =405) were examined. Variants were confirmed via Sanger sequencing, and segregation analysis was performed when possible. We identified 137 distinct likely pathogenic or pathogenic variants (according to ACMG criteria) across 51 genes in 163/1,924 patients [42.9% male, 85.9% White, 68.7% isolated dystonia, median AAO 19 years]. This included 153/1,895 index patients, resulting in a diagnostic yield of 8.1%. Notably, 77/137 (56.2%) of these variants were novel, with recurrent variants in EIF2AK2 , VPS16 , KCNMA1 , and SLC2A1 , and novel variant types such as two splice site variants in KMT2B , supported by functional evidence. Additionally, 321 index patients (16.9%) harbored variants of uncertain significance in 102 genes. The most frequently implicated genes included VPS16 , THAP1 , GCH1 , SGCE , GNAL , and KMT2B. Presumably pathogenic variants in less well-established dystonia genes were also found, including KCNMA1 , KIF1A , and ZMYND11. At least six variants (in ADCY5 , GNB1 , IR2BPL, KCNN2 , KMT2B , and VPS16 ) occurred de novo, supporting pathogenicity. ROC curve analysis indicated that AAO and the presence of generalized dystonia were the strongest predictors of a genetic diagnosis, with diagnostic yields of 28.6% in patients with generalized dystonia and 20.4% in those with AAO < 30 years. This study provides a comprehensive examination of the genetic landscape of dystonia, revealing valuable insights into the frequency of dystonia-linked genes and their associated phenotypes. It underscores the utility of exome sequencing in establishing diagnoses within this heterogeneous condition. Despite prescreening, presumably pathogenic variants were identified in almost 10% of patients. Our findings reaffirm several dystonia candidate genes and expand the phenotypic spectrum of some of these genes to include prominent, sometimes isolated dystonia.

    A new genus and species of the family Pseudocyclopidae, Sipadantoniusroihani gen. et sp. nov., was described based on specimens collected using a light trap in the marine cave of Sipadan Island, Sabah, Malaysia. The new genus is most related to Pinkertonius, primarily based on the similarity observed in the armament of ancestral segment IV of the male antennules, the armament of the female P5 Exp-3, the segmentation of the male P5, the armament of the maxillular basal exite, and the relative length of the ancestral segment XXVII of the antennules. Nevertheless, it distinguishes itself from Pinkertonius and all other genera of the family by the absence of the lateral seta of the basis of all swimming legs, the presence of an inner seta on the coxa of the female P5, the reduction of furcal setae I and III, as well as the specific armament of the ancestral segment XX of the antennules and the maxillular coxal endite. The female of Sipadantoniusroihani gen. et sp. nov. has aesthetascs on the ancestral segments IV and XX of the antennules, as well as six setae on the maxillular coxal endite, exhibiting the most plesiomorphic characteristics of the family Pseudocyclopidae. The latter characteristic has not been recorded in the order Calanoida. It was hypothesised that the new species was a particle feeder living in the pelagic zone of the marine cave. The existence of the new species supported the assumption that the regional distribution of the family Pseudocyclopidae exhibited the Tethyan track, which might have been the subsequent result of the colonisation of the habitats prior to the closure of the Tethys Sea.

    Bilateral middle cerebellar peduncle (MCP) infarction is a rare manifestation of ischemic stroke. We report a middle-aged male patient who presented with acute onset of vertigo, left ear deafness, and severe ataxia. Magnetic resonance imaging (MRI) of the brain confirmed the presence of infarction in the bilateral middle cerebellar peduncles due to stenosis of the posterior circulation arteries. This case highlights the importance of recognizing this clinical syndrome, as the symptoms may resemble those of peripheral vestibulopathy. Timely recognition is of paramount importance, given that untreated posterior circulation stroke can result in poor neurological outcomes.

    BACKGROUND: Breast cancer (BC) is the most popular and dangerous cancer, with a high mortality rate. Hematological parameters are often used in routine diagnosis of numerous disorders. Therefore, the study aimed to evaluate hematological parameters amongst women with and without BC.

    METHODOLOGY: Briefly, 200 blood samples (100 cases and 100 controls) were collected at Life Center of Breast Cancer Control, Ibb City, Yemen. The whole blood samples were tested immediately for complete blood count (CBC) parameters. Socio-demographic and reproductive characteristics were collected by using a standardized questionnaire. Kolmogorov-Smirnov test, Unpaired t-test, Mann-Whitney test, Fisher's exact test and chi-square test for trends were calculated using GraphPad Prism 8.0.1. P-values ≤0.05 were statistically significant.

    RESULTS: The mean and standard deviation (SD) revealed significant differences between BC group and the healthy control group attributed to the variables of age (P<0.0001), weight (P<0.0001), residence (P=0.0218), employment state (P<0.0001), economic state (P=0.0003), education levels (P<0.0001), regular exercise (P<0.0001) and a strict diet (P<0.0008). Marital state, marital age, number of births, and use of contraceptives demonstrated statistical significance (P<0.0001, P=0.0008, P=0.0009, and P<0.0001, respectively). Additionally, Hb, RBCs, WBCs count, neutrophils, lymphocytes and monocytes displayed significant differences (P=0.0393, P=0.0045, P=0.0327, P=0.0441, P=0.0098 and P<0.0001, respectively).

    CONCLUSION: Hb, RBCs, WBCs, neutrophils, lymphocytes, monocytes and other parameters scored high points of evidence for BC surveillance. Further studies are required to evaluate hematological parameter differences and biochemical parameters after or during chemotherapy or mastectomy.

    BACKGROUND: Early detection of colorectal cancer (CRC) is crucial to enhance the disease treatment and prognosis of patients. Colonoscopy remains the gold standard for CRC detection; however, it requires trained personnel with expensive tools. Currently, serum metabolites have been discovered to be used to discriminate patients with polyps and CRC. This study aimed to identify the most commonly detected predictive serum metabolites for polyps and CRC.

    METHODS: A systematic search of the Web of Science, PubMed, and Cochrane Library databases was conducted using PRISMA guidelines. Ten studies investigating serum metabolite biomarkers of CRC and polyps using different analytical platforms and study populations were included. QUADOMICS tool was used to analyse the quality of the included studies. All reported metabolites were then enriched into the pathways using MetaboAnalyst 5.0.

    RESULTS: We found that several potential signature metabolites overlapped between studies, including tyrosine, lysine, cystine, arabinose, and lactate for CRC and lactate and glutamate for polyps. The most affected pathways related to CRC were the urea cycle, glutathione metabolism, purine metabolism, glutamate metabolism, and ammonia recycling. In contrast, those affected in the polyps were the urea cycle, glutamate metabolism, glutathione metabolism, arginine and proline metabolism, and carnitine synthesis.

    CONCLUSIONS: This review has found commonly detected serum metabolites for polyps and CRC with huge potential to be used in clinical settings. However, the differences between altered pathways in polyps and CRC, other external factors, and their effects on the regulation level, sensitivity, and specificity of each identified metabolite remained unclear, which could benefit from a further extensive cohort study and well-defined analysis equipment.

    The harm caused by deepfake face images is increasing. To proactively defend against this threat, this paper innovatively proposes a destructive active defense algorithm for deepfake face images (DADFI). This algorithm adds slight perturbations to the original face images to generate adversarial samples. These perturbations are imperceptible to the human eye but cause significant distortions in the outputs of mainstream deepfake models. Firstly, the algorithm generates adversarial samples that maintain high visual fidelity and authenticity. Secondly, in a black-box scenario, the adversarial samples are used to attack deepfake models to enhance their offensive capabilities. Finally, destructive attack experiments were conducted on the mainstream face datasets CASIA-FaceV5 and CelebA. The results demonstrate that the proposed DADFI algorithm not only improves the generation speed of adversarial samples but also increases the success rate of active defense. This achievement can effectively reduce the harm caused by deepfake face images.

    Data imputation strategies are necessary to address the prevalent difficulty of missing values in data observation and recording operations. This work utilizes diverse imputation methods to forecast and complete absent values inside a financial time-series dataset, specifically the daily prices of gold. The predictive accuracy of imputed data is assessed in comparison to the original entire dataset to ensure its robustness. The imputation methods are validated using actual closing price data obtained from a daily gold price website. The examined approaches include mean imputation, k-nearest neighbor (KNN), hot deck, random forest, support vector machine (SVM), and spline imputation. Their performance is evaluated based on several metrics, including mean error (ME), mean absolute error (MAE), root mean square error (RMSE), mean percentage error (MPE), and mean absolute percentage error (MAPE). The results indicate that the KNN approach consistently performs better than other methods in terms of all accuracy measures. Nevertheless, the precision of all techniques decreases as the proportion of missing data rises. Therefore, the KNN approach is suggested because to its exceptional performance and dependability in imputation tasks.

    This study examines the effects of energy resources in the form of clean and unclean energy on the economic progress of 30 selected developed economies. This study used data from 1990 to 2020 and it employs the CS-ARDL method to obtain results. The results present that both clean and unclean energy significantly stimulate economic progress. The findings further expose that foreign investment resources in the form of inflow are significant factors that accelerate economic progress in developed economies. The results reveal that tourism development, capital accumulation, and exports are significant factors in boosting economic progress in the selected economies. Estimates from Dumitrescu and Hurlin's method for heterogeneous panels confirm the presence of the feedback-effect hypothesis for unclean energy, while the energy-conservation hypothesis holds for clean energy. This study suggests that targeting low-cost clean energy production is crucial for promoting economic growth and protecting the environment through carbon mitigation strategies. There is also a need to develop a policy framework that emphasizes the transformation of industry towards clean energy at a macro level. Furthermore, transitioning from unclean to clean energy may enhance economic progress by improving environmental quality norms in the selected developed economies. Finally, policies for tourism development, export improvement, and increased inflow of FDI should be directed towards fostering clean energy agreements and achieving environment-friendly economic progress in developed economies.

    OBJECTIVES: This study aimed to examine the causal relationships between peripheral immune cell counts and prostate cancer, adhering to Mendelian Randomization reporting guidelines for transparency and reproducibility.

    METHODS: In this study, bidirectional Mendelian randomization (MR) analysis, which includes MR-Egger, weighted median, weighted mode, and inverse variance weighted (IVW) approaches, was utilized to evaluate the bidirectional causal relationship between peripheral immune cell counts and the risk of PCa.

    RESULTS: The primary analysis using the IVW method suggests a potential causal association between basophil counts and the risk of prostate cancer (PCa), with an odds ratio (OR) of 1.111 and a 95% confidence interval (CI) of 1.011-1.222 (P = 0.028). Conversely, non-causal associations have been observed between other peripheral immune cell types, such as white blood cells, neutrophils, lymphocytes, eosinophils, or monocytes, and the incidence of PCa (P values > 0.05). Furthermore, although reverse analysis indicated a causal link between PCa and the counts of leukocytes and neutrophils (OR = 1.013; 95% CI = 1.002-1.225; P = 0.018 and OR = 1.013; 95% CI = 1.002-1.025; P = 0.019), no causal association was detected between PCa and basophil count (P value > 0.050).

    CONCLUSION: This study suggests a potential bidirectional link between peripheral immune cells and prostate cancer, but inconsistencies in Mendelian Randomization methods mean these findings are preliminary and require further investigation.

    BACKGROUND: The standard treatment for thymomatous myasthenia gravis (TMG) patients is thymectomy, whereas its role in non-TMG (NTMG) is still under debate. The objective of this study is to assess myasthenia gravis (MG) outcomes of thymectomy using the uniportal video-assisted thoracoscopic surgery (UVATS) technique for both groups and evaluate the procedure's efficacy and safety.

    METHODS: We retrospectively collected data from January 2019 to December 2022 at Hospital Kuala Lumpur. The Myasthenia Gravis Activities of Daily Living (MG-ADL) scoring and the Myasthenia Gravis Foundation of America's Post Interventional Score (MGFA-PIS) measured our primary outcome. Secondary outcomes included surgery-related morbidity. All patients underwent a UVATS thymectomy, with the incision at the right anterior axillary line at the 5th intercostal space.

    RESULTS: Out of 26 patients, 22 were analysed. The MG-ADL scores indicated a significant mean score reduction post-surgery [6.9; 95% confidence interval (CI): 4.42 to 9.67; P<0.001]. NTMG patients exhibited a greater decrease in MG-ADL mean score than TMG patients {9.5 [standard deviation (SD) 4.8] vs. 6.1 (SD 5.4) P<0.001}. The MGFA-PIS showed complete stable remission (CSR) rates of 43% for TMG and 25% for NTMG patients. Surgical morbidity was observed in 13% of patients, of which were myasthenic crisis, difficult extubation due to carbon dioxide (CO2) retention and subcutaneous emphysema.

    CONCLUSIONS: Thymectomy via UVATS is an effective and safe approach for improving symptoms in both TMG and NTMG patients.

    BACKGROUND: The 26S non-ATPase regulatory subunit 11 (PSMD11) is a multiprotein complex that participates in the ATP-dependent degradation of ubiquitinated proteins and is essential to the regulation of embryonic stem cell proteasome activity. PSMD11 has been demonstrated to be a factor contributing to the emergence and progression of cancer cells. However, the prognostic value and potential biological function of PMSD11 in lung adenocarcinoma (LUAD) remains unclear. The aim of this study was to comprehensively investigate the prognostic and biological value of PSMD11 in LUAD.

    METHODS: We primarily endeavored to comprehensively investigate the prognostic and predictive value of PSMD11 in patients with LUAD. Additionally, we aimed to further clarify the underlying mechanisms of PSMD11 in LUAD tumorigenesis and progression via rigorous bioinformatics analyses, including expression analysis, survival analysis, clinicopathological analysis, immune microenvironment analysis, somatic mutation analysis, drug analysis, and cuproptosis analysis. Subsequently, we examined effect of PSMD11 expression on immune escape in a non-small cell lung cancer (NSCLC) cell-T cell coculture model.

    RESULTS: We found that PSMD11 had a significantly higher expression in LUAD tissues than in normal lung tissues. Three clinical characteristics (age, stage, and overall survival event) exhibited significant differences between the PSMD11 high- and low-expression groups. In biological function, PSMD11 appears to exert its tumorigenic effects predominantly in pathways related to DNA replication and membrane-gated channel functions. Notably, we observed that PSMD11 exhibited the strongest positive correlation with T helper 2 cells, gamma-delta T cells, and T regulatory cells and the highest negative correlation with B cells, mast cells, and CD8+ T cells. Furthermore, we found that the expression of cuproptosis genes (DLAT, DLD, and PDHA1) was positively correlated with the expression of PSMD11 (P<0.001).

    CONCLUSIONS: These results indicate that PSMD11 has the potential to be a novel therapeutic target and sensitive biomarker for patients with LUAD.

    Mandarin fish (Siniperca chuatsi) fed with an artificial diet is progressively gaining popularity, which is important for reducing product prices and resource consumption. However, food is the decisive factor of intestinal microbes, and the profound effects of change in their feeding habit on intestinal microbes of mandarin fish have not been revealed. In the present study, live bait fish and artificial diet were used to feed mandarin fish for 8 weeks to study the effect of different feeding habits on the histology, microbiota structure and dominant bacteria of gut in mandarin fish. The results indicated that feeding with the artificial diet significantly increased the intestinal villi height and muscular thickness in the hindgut of mandarin fish. In addition, the microbiota results showed that there were significant differences of beta diversity of gut microbiota in mandarin fish fed with different diets. At the genus level, feeding artificial diets significantly increased the abundance of Weissella in the mandarin fish gut. Furthermore, two Weissella bacteria were identified and characterized from the midgut contents of mandarin fish fed with artificial diet. Based on 16S rRNA gene sequencing, nine strains were assigned as Weissella confusa (RM125), and one as Weissella cibaria (SJ548). Biochemical analyses based on the VITEK2 method revealed a pattern of metabolic activities against W. confusa RM125 and W. cibaria SJ548, with 13 positive and 29 negative results, respectively. W. confusa RM125 and W. cibaria SJ548 exhibited sensitivities toward a variety of pathogens, including V. harveyi, S. aureus and V. parahaemolyticus, E. coli, A. hydrophila, S. enterica, V. anguillarum, and V. alginolyticus, indicating potential probiotics. Therefore, our results confirmed that the transformation of feeding habit altered the structure, microbial composition and dominant bacteria in gut of mandarin fish, and provided evidence that Weissella might play a crucial role in the digestion and absorption of artificial diet in mandarin fish.

    OBJECTIVE: Strengthening youth sports and comprehensively promoting the participation of Chinese university students in sports to enhance their social acceptance are key initiatives for delivering high-quality talent for China's economic and social development.

    METHODS: Using the China Comprehensive Social Survey as the data source and considering social mentality and social identity, we constructed corresponding statistical models to explore how sports participation influences the social identity (class identity, economic status, and emotional belonging) of Chinese university students.

    RESULTS: Regarded from a holistic perspective, sports participation can enhance the social identity of college students in all its aspects, and the benefits of sports participation are positively related to its frequency. Under the condition of social mentality, sports participation has a positive effect on the social identity of college students in general and a nonsignificant effect only on certain dimensions. Under the social identity condition, the significance of sports participation for college students' social identity decreases from lower to higher levels of education.

    CONCLUSION: Sports participation significantly enhances the social identity of Chinese university students, and the specific mechanism of the enhancement varies across the social mentality and social identity conditions. In this context, strengthening the role of sports participation in promoting the social identity of college students in the new era is necessary. Deepening the ideological content of physical education courses should be taken as the starting point to enhance the effectiveness of sports participation on the social identity of college students under the condition of social mentality. The effectiveness of sports participation on the social identity of college students with different social identities should be differentiated and enhanced.

    INTRODUCTION: Improving the quantity and quality of veterinary talent cultivation is an urgent issue to address in current veterinary education and is key to enhancing veterinary talent competitiveness. Starting from an industrial perspective, the introduction of scientific analytical methods for studying veterinary talent competitiveness offers a new view on veterinary education and helps to improve the quality of veterinary education and talent cultivation.

    METHODS: This study develops a veterinary talent competitiveness evaluation index based on the characteristics of veterinary talent. It proposes a visual method to analyze the level and spatiotemporal evolution of veterinary talent competitiveness using the Entropy method and ArcGIS tools, with Western China as a case study. Data is collected from 12 regions in Western China, spanning 2015 to 2021.

    RESULTS: The results show that the method not only evaluates the current state of veterinary talent competitiveness but also considers temporal and spatial evolution, achieving good evaluation effectiveness and high accuracy, thereby guiding the improvement of veterinary education and talent cultivation.

    DISCUSSION: Based on the research findings, the study suggests improving the quality of veterinary education and talent cultivation through measures such as strengthening talent resource development, addressing regional imbalances, and promoting spatial integration to achieve a virtuous cycle between veterinary education and industrial development.

    BACKGROUND AND PURPOSE: Antimicrobial resistance (AMR) has emerged as a significant global concern. To combat this growing threat, various strategies have been employed, including the use of plant extracts and the biosynthesis of nanoparticles (NPs). The current study was designed to evaluate the phytochemical analysis of ginger (Zingiber officinale) extracts, characterize the silver nanoparticles (AgNPs) and to see their antibacterial potentials against multi-drug resistant (MDR) bacterial strains.

    METHODS: The extracts were prepared and initially assessed for their phytochemical composition and antibacterial activity. Then, AgNPs were synthesized from these extracts at room temperature, and various analytical techniques, including UV-visible spectroscopy, X-ray diffraction (XRD), ATIR-FTIR, zeta sizer, scanning electron microscopy (SEM), and energy-dispersive X-ray analysis (EDXA), were used to characterize the NPs. After confirmation of prepared NPs, they were subjected to their antibacterial activity.

    RESULTS: HPLC analysis demonstrated the presence of eight phytoconstituents in organic ginger extracts. The absorption spectra of the silver suspension exhibited surface plasmon resonance peaks with maxima between 420 and 448 nm. Functional groups like C-H, N-H, OH, C-O-C, C=O, and C-O were identified in both the organic and aqueous extracts of Z. officinale, playing a key role in the formation of AgNPs, as characterized by ATR-FTIR analysis. Both ginger organic and aqueous extract synthesized AgNPs crystalline structure was shown in XRD analysis and the particle size distribution showed average diameter of 200.5 nm of AgNPs from aqueous extracts. Scanning Electron Microscopy displayed spherical structure and EDA results showed the percentage of elements in synthesized AgNPs using plant extracts. Most promising antibacterial activity was obtained against Escherichia coli ie 20.83±0.53 for 100 µg/mL.

    CONCLUSION: The results of the current study showed that AgNPs synthesized from different ginger extracts have promising antibacterial properties and can be potential candidates for alternative treatment options for bacterial infections.
