Effect of the Cross-rolling Process on the Microstructures and Mechanical Properties of 9Cr-1W ODS Steel
Authors: Kim Bu-An , Noh Sanghoon
Published: February 2025

This study employed a cross-rolling process to fabricate oxide dispersion strengthened (ODS) steel plates and investigated their microstructures and mechanical properties. The 9Cr-1W ODS ferritic steel was fabricated using mechanical alloying and hot isostatic pressing. The hot cross-rolling process produced thick ODS ferritic steel plates with a well-extended rectangular shape. The working direction greatly affected the grain structure and crystal texture of the ODS ferritic steel. Cross-rolled plates showed fine micro-grains with random crystal orientation, while unidirectionally rolled plates exhibited a strong orientation with larger, elongated grains. Transmission electron microscopy revealed a uniform distribution of nano-oxide particles in both rolling methods, with no major differences. Tensile tests of the ODS ferritic steel plates showed that the unidirectional rolled plates had anisotropic elongation, while cross-rolled plates exhibited isotropic behavior with uniform elongation. Cross-rolling produced finer, more uniform grains, reducing anisotropy and improving mechanical properties, making it ideal for manufacturing wide ODS steel components.

Authors: Cho Jun-Min , Seo Yong-Jun , Han Yoon-Soo
Published: February 2025

This study focused on optimizing the digital light processing (DLP) 3D printing process for high-precision ceramic components using alumina-based slurries. Key challenges, such as cracking during debinding and precision loss due to slurry sedimentation, were addressed by evaluating the exposure time and the nano-to-micro alumina powder ratios. The optimal conditions—exposure time of 15 seconds and a 1:9 mixing ratio—minimized cracking, improved gas flow during debinding, and increased structural precision. Microchannels with diameters above 1.2 mm were successfully fabricated, but channels below 0.8 mm faced challenges due to slurry accumulation and over-curing. These results establish a reliable process for fabricating complex ceramic components with improved precision and structural stability. The findings have significant potential for applications in high-value industries, including aerospace, energy, and healthcare, by providing a foundation for the efficient and accurate production of advanced ceramic structures.

Authors: Choi Sunghee , Kim Seulgi , Woo Seojin , Lee Dongju
Published: February 2025

Supercapacitors, renowned for their high power density and rapid charge-discharge rates, are limited by their low energy density. This limitation has prompted the need for advanced electrode materials. The present study investigated reduced graphene oxide (rGO) in two distinct structures, as a film and as an aerogel, for use as supercapacitor electrodes. The rGO film, prepared by vacuum filtration and thermal reduction, exhibited a compact, lamellar structure, while the aerogel, synthesized through hydrothermal treatment, was a highly porous three-dimensional network. Electrochemical analyses demonstrated the aerogel’s superior performance, as shown by a specific capacitance of 121.2 F/g at 5 mV/s, with 94% capacitance retention after 10,000 cycles. These findings emphasize the importance of structural design in optimizing ion accessibility and charge transfer. They also demonstrate the potential of rGO aerogels for increasing the energy storage efficiency of advanced supercapacitor systems.

Published: February 2025

BACKGROUND

Shifting from the inflammatory to the proliferative phase represents a pivotal step during managing diabetic foot ulcers (DFUs); however, existing medical interventions remain insufficient. MicroRNAs (miRs) highlight notable capacity for accelerating the repair process of DFUs. Previous research has demonstrated which miR-122-5p regulates matrix metalloproteinases under diabetic conditions, thereby influencing extracellular matrix dynamics.

AIM

To investigate the impact of miR-122-5p on the transition from the inflammatory to the proliferative stage in DFU.

METHODS

Analysis for miR-122-5p expression in skin tissues from diabetic ulcer patients and mice was analyzed using quantitative real-time polymerase chain reaction (qRT-PCR). A diabetic wound healing model induced by streptozotocin was used, with mice receiving intradermal injections of adeno-associated virus -DJ encoding empty vector or miR-122. Skin tissues were retrieved at 3, 7, and 14 days after injury for gene expression analysis, histology, immunohistochemistry, and network studies. The study explored miR-122-5p’s role in macrophage-fibroblast interactions and its effect on transitioning from inflammation to proliferation in DFU healing.

RESULTS

High-throughput sequencing revealed miR-122-5p as crucial for DFU healing. qRT-PCR showed significant upregulation of miR-122-5p within diabetic skin among DFU individuals and mice. Western blot, along with immunohistochemical and enzyme-linked immunosorbent assay, demonstrating the upregulation of inflammatory mediators (hypoxia inducible factor-1α, matrix metalloproteinase 9, tumor necrosis factor-α) and reduced fibrosis markers (fibronectin 1, α-smooth muscle actin) by targeting vascular endothelial growth factor. Fluorescence in situ hybridization indicated its expression localized to epidermal keratinocytes and fibroblasts in diabetic mice. Immunofluorescence revealed enhanced increased presence of M1 macrophages and reduced M2 polarization, highlighting its role in inflammation. MiR-122-5p elevated inflammatory cytokine levels while suppressing fibrotic activity from fibroblasts exposed to macrophage-derived media, highlighting its pivotal role in regulating DFU healing.

CONCLUSION

MiR-122-5p impedes cutaneous healing of diabetic mice via enhancing inflammation and inhibiting fibrosis, offering insights into miR roles in human skin wound repair.
Platelets indices clinical implications in diabetes mellitus: A broader insight
Authors: Mirghani Hyder Osman
Published: February 2025

Platelet indices (PIs) including high mean platelet volume (MPV), plateletcrit (PLC), and platelet distribution width (PLDW) are associated with poor glycemic control. In addition, they can indicate prothrombotic and procoagulation risk among patients with diabetes. PI measurement is cheap, quick and fits healthcare system needs in remote outreaching areas in low-income countries. However, a broader insight into their clinical implications in diabetes is lacking. To achieve a wider understanding, we reviewed PubMed/MEDLINE, Google Scholar and Cochrane Library for relevant articles investigating the role of PIs in diabetes mellitus. No limitation to the publication date was applied, which included all articles published up to August 17, 2024. The terms used were MPV, PLC, PLDW, platelet large cell ratio, glycated hemoglobin (HbA1c), PIs, platelet activity and diabetes mellitus. Out of the 790 articles retrieved, 187 full texts were reviewed, and 44 were included. PIs, when measurements are done promptly and within 2 h, could be short-term pointers to glycemic control in the life span of the platelets (2 wk). PIs are easy to perform, cheap and useful in remote outreaching areas with limited facilities where measurement of HbA1c is not available or cost-effective. However, PIs are not specific and are affected by demographic factors, such as pregnancy, renal failure, medications, hemoglobin and duration of diabetes. PIs could be implemented with daily blood glucose to inform doctors in low-income countries about their patients' glycemic control and cardiovascular risk. An important application might be when blood glucose control is needed quickly (before elective surgery).

Published: February 2025

BACKGROUND

Diabetes mellitus (DM) is a rapidly growing global health emergency of the 21st century. Comorbidities, such as DM and depression, are common, presenting challenges to the healthcare system.

AIM

To investigate the prevalence of depression and its associated factors in patients with DM and to strengthen the management of depression in this patient group.

METHODS

Participants were selected from the 2018 China Health and Retirement Longitudinal Study. Depressive symptoms were assessed using the 10-item Center for Epidemiological Studies Depression Scale, with a score of 10 or more indicating depression. Group differences were compared using analysis of variance and χ 2 tests. Binary logistic regression was conducted to explore the odds ratios (ORs) of independent variables. Following Andersen’s behavioral model, predisposing, enabling, health need, and health behavior variables were introduced stepwise into the logistic model.

RESULTS

Of the 1673 patients with diabetes, 41.4% had depressive symptoms. Regarding the predisposing characteristics, patients who were male (OR 0.426, P < 0.05), married (OR 0.634, P < 0.05), and received a high school education or higher (OR 0.432, P < 0.05) reported fewer depressive symptoms. Healthcare needs, including better self-rated health (OR 0.458 for fair and OR 0.247 for good, P < 0.05) and more sleep (OR 0.642, P < 0.05), were associated with a lower likelihood of depressive symptoms. In contrast, pain (OR 1.440 for mild and OR 2.644 for severe, P < 0.05) and impairment in the basic activities of daily living (OR 1.886, P < 0.05) were inversely associated. Additionally, patients highly satisfied with healthcare services (OR 0.579, P < 0.05) were less likely to have depressive symptoms.

CONCLUSION

Nearly half of the patients with DM reported depressive symptoms, which were strongly associated with predisposing characteristics and healthcare needs, particularly physical pain and impairment in basic activities of daily living. Our study emphasizes the significance of enhanced screening and intervention for depression in diabetes care along with improved management of functional impairments.
Dysfunctional glucose metabolism triggers oxidative stress to induce kidney injury in diabetes
Authors: Gao Meng , Dai Meng-Ting , Gong Guo-Hua
Published: February 2025

In this editorial, we discussed the article published in the recent issue of the World Journal of Diabetes . To understand the effect of mizagliflozin on kidney injury induced by diabetes, we focused on the mechanisms by which high glucose triggers oxidative stress and contributes to kidney injury in diabetes. The high level of unmetabolized glucose reaching the kidney triggers glucose reabsorption by renal tubules, which elevates the cellular glucose level of renal cells. High glucose induces lactate dehydrogenase overexpression and thus shifts glucose metabolism, which causes mitochondrial dysfunction. Mitochondria generate approximately 90% of the reactive oxygen species in cells, whose dysfunction further alters glucose metabolism and enhances reactive oxygen species generation. Oxidative stress stimulates proinflammatory factor production and kidney inflammatory injury. Mizagliflozin decreases glucose reabsorption and thus ameliorates diabetes-induced kidney injury.

Published: February 2025

BACKGROUND

Early diagnosis of left ventricular diastolic dysfunction (LVDD) is essential for preventing heart failure. B-type natriuretic peptide (BNP) is a viable marker for predicting LVDD, as elevated BNP levels have been associated with worsening LVDD in patients with diabetes over time. However, the utility of BNP as a diagnostic marker in diabetes is controversial, as BNP levels are often low in overweight individuals.

AIM

To examine the effectiveness of BNP levels and fragmented QRS (fQRS) on electrocardiography for diagnosing LVDD in patients with type 2 diabetes.

METHODS

This retrospective cohort study included 303 patients with type 2 diabetes (67.4 ± 12.3 years old) with preserved ejection fraction (EF) ≥ 50% admitted to Toyama University Hospital for glycemic management and comorbidity evaluation between November 2017 and April 2021. All participants underwent plasma BNP measurement, electrocardiography, and echocardiography. Cardiologists who were blinded to the BNP results assessed the electrocardiograms and echocardiograms. Subgroup analyses were conducted for overweight individuals.

RESULTS

Receiver operating characteristic (ROC) curve analysis determined optimal BNP cut-off values of 34.8 pg/mL and 7.2 pg/mL for diagnosing LVDD in non-overweight [area under the ROC curve (AUC): 0.70] and overweight (AUC: 0.55) groups, respectively (P = 0.040). In the overweight subgroup, fQRS showed greater diagnostic accuracy for LVDD (AUC: 0.67), indicating moderate diagnostic utility compared with the low performance of the BNP cutoff of 35 pg/mL (AUC: 0.52) (P = 0.010). Multivariate analyses confirmed that fQRS was superior to BNP for LVDD diagnosis regardless of the patient’s weight.

CONCLUSION

A BNP level ≥ 35 pg/mL in non-overweight individuals may be a reliable LVDD marker. Additionally, fQRS was more effective than BNP in diagnosing LVDD irrespective of the patient’s weight. fQRS can complement BNP in the early detection of LVDD, especially in overweight patients, potentially improving early detection and mitigating progression to heart failure with preserved EF in patients with type 2 diabetes.

Published: February 2025

BACKGROUND

Diabetes mellitus (DM) is linked to an earlier onset and heightened severity of urinary complications, particularly bladder dysfunction, which profoundly impacts patient quality of life. Overactive bladder (OAB) is a common storage disorder of the lower urinary tract and is characterized by urgency, frequency, and nocturia. Several factors contribute to bladder dysfunction in diabetic individuals, including changes in urothelial signaling, detrusor morphology, and central nervous system regulation. The transient receptor potential vanilloid type 1 channel, expressed by bladder urothelial cells, is upregulated in OAB and plays a crucial role in ATP release during bladder filling. This ATP release subsequently activates purinergic receptor P2X3, further exacerbating OAB symptoms.

AIM

To clarify the mechanism of Roux-en-Y gastric bypass (RYGB) metabolic surgery to improve OAB in type 2 DM (T2DM).

METHODS

The model of T2DM was induced by feeding a high-fat diet to mice for 16 weeks. After 16 weeks, sham operation and RYGB operation were performed. The related indexes of glucose metabolism were also detected to evaluate the therapeutic effect, and the recovery degree of bladder function and micturition behavior of mice was assessed by urodynamics and micturition spot analysis.

RESULTS

Compared with the normal mice in the sham group, T2DM mice had increased urine spot count, uncontrolled urination behavior, shortened urination interval, and reduced bladder capacity. Immunohistochemistry and immunofluorescence costaining showed that Transient receptor potential vanilloid type 1 (TRPV1) and purinergic receptor P2X3 were both expressed in mouse bladder epithelial layer, and they had the same localization. In the bladder of T2DM mice, the mRNA and protein expression of TRPV1 and P2X3 were significantly increased. The ATP content in urine of T2DM mice was significantly higher than that of the sham group. After RYGB operation, the glucose metabolism index of the RYGB group was significantly improved compared with the OAB group. Comparing the results of urine spots, urodynamics, and histology, it was found that the function and morphological structure of the bladder in the RYGB group also recovered obviously. Compared with the OAB group, the expression of TRPV1 and P2X3 in the RYGB group was downregulated, and the level of inflammatory factors was significantly decreased. RYGB significantly decreased the content of ATP in urine and activated AMPK signaling.

CONCLUSION

RYGB downregulated the expression of TRPV1 by inhibiting inflammatory factors, thus inhibiting the enhancement of P2X3 by TRPV1. RYGB directly inhibited the activity of P2X3 by inhibiting ATP synthesis in the bladder epithelium to improve OAB.

Type 1 diabetes (T1D) is a chronic organ-specific autoimmune disorder characterized by a progressive loss of the insulin-secreting pancreatic beta cells, which ultimately results in insulinopenia, hyperglycemia and lifelong need for exogenous insulin therapy. In the pathophysiological landscape of T1D, T helper 17 cells (Th17 cells) and their hallmark cytokine, interleukin (IL)-17, play pivotal roles from disease onset to disease progression. In this narrative mini-review, we discuss the dynamic interplay between Th17 cells and IL-17 in the context of T1D, providing insights into the underlying immunologic mechanisms contributing to the IL-17-immunity-mediated pancreatic beta-cell destruction. Furthermore, we summarized the main animal and clinical studies that investigated Th17- and IL-17-targeted interventions as promising immunotherapies able to alter the natural history of T1D.

Authors: Cilavdaroglu E. , Yamak U.S.
Published: February 2025

In this study, the broiler performance of Turkish Gerze chickens was investigated. One hundred and thirty day-old chicks were reared  under intensive conditions until 20 weeks of age to examine whether administering a vitamin supplement via their drinking water would  affect broiler performance. During this period, one group received the vitamin supplement, starting at four weeks of age, and the other  (the control group) did not. At 20 weeks old, the chickens given the vitamin supplement had an average live weight of 1686 g and a feed  conversion ratio of 4.47, while the control group was significantly lighter, at 1408 g, with a feed conversion ratio of 4.63. Dressing  percentages were not significantly affected by vitamin supplementation, and averaged around 68%. The proportion of edible giblets also  did not significantly differ between the two groups, contributing approximately 5%–6% of the carcass. The largest carcass component in  both treatment groups was the legs, constituting 32%–33% of the carcass in males and 28% in females. Breast meat made up 22%–27% of  the carcass, and this was not significantly influenced by vitamin supplementation. The pH and colour of the breast and leg meat were  evaluated as meat quality traits, and these quality parameters were within acceptable limits for poultry meat for all groups.

Emotional labor and burnout among hotel frontline employees in the Philippine tourism
Authors: Larena Chizanne Sarabia
Published: February 2025

Emotional labor is a quality service indicator that demands control of emotions and a display of facial expressions. This study investigated the psychosocial dimensions of emotional labor and burnout among hotel frontline employees in the tourism industry. The participants were frontline employees (n = 302) selected through stratified random sampling technique. To analyze the data, frequency distribution, percentage, means, standard deviation, Pearson Product Moment Correlation Coefficient, and Stepwise Regression were utilized. Results show that there is a significant relationship between emotional labor and burnout. Specifically, it reveals that surface acting, but not deep acting, is significantly related to burnout. Hotel frontline employees’ display of emotion-regulated work can be exasperating, and emotional labor, over time, contributes to burnout. Surface acting is a painstaking effort, leaving the front-liner more tired. Deep acting is a natural tendency among Filipinos to empathize with client’s needs. Nevertheless, managing emotional state is necessary in one-on-one mutual consultation with client service, otherwise, when not appropriately intervened, it will lead to unfavorable mental health concerns, such as burnout. Hence, periodic psychosocial training, cognitive techniques, and reframing of mind are helpful strategies to help front-liners control their emotions.

Sources of Syntactic Ambiguity in Contemporary Arabic: A Corpus Study
Authors: Abdelkader Drissi Otmane , Yagi Sane Mohamed , Sawalha Majdi Shaker
Published: February 2025

Recently, Arabic began gaining ground in the area of research within Natural Language Processing (NLP). This study constructs a syntactically annotated corpus based on the framework of I3rab to discuss the sources of syntactic ambiguities in Contemporary Arabic. The corpus of this study is a sub-corpus of the Jordan Comprehensive Contemporary Arabic Corpus (JCCA). It contains over 100000 words gathered from different written and spoken texts. Annotation involves manually adding the grammatical function of each word in its immediate context. Findings show that Contemporary Arabic exhibits different sources of syntactic ambiguity. The omission of diacritics in Contemporary Arabic texts is considered the main problem that causes syntactic ambiguity. Pro-drop, free word-order and Idafa construction ambiguities are deeply related to the omission of diacritics. Prepositional phrase attachment is also one of the challenging phenomena for the parser to produce the proper syntactic representation. Results also show that gender, number, and case agreements in Contemporary Arabic elevate the possibility of facing different kinds of syntactic ambiguities, including conjunct and adverbial ambiguity.

Published: February 2025

This study aimed at investigating the effect of teaching based allosteric learning model in solving geometric problem among eighth grade students with different spatial perceptions. The study adopted the experimental methodology and the quasi-experimental design. The study subjects were selected from the 8th grade students from two schools in the capital city Amman-Jordan. Two classes were randomly assigned in each school, one of them is experimental, studied according to the "Allosteric Learning Model", and the other is the control one which studied according to the usual method. By combining classes, the number of subjects of the experimental group became (60) male and female students, and the number of subjects of the control group became (55) male and female students. The teaching material was prepared according to the teaching model, and the “Geometric Problem Solving Test” and The “Spatial Visualizations Scale” were used for the research purposes. The results showed that there were statistically significant differences (α = 0.05) in solving the geometric problem attributed to the teaching method, in favor of the experimental group, while the results showed no statistically significant differences (α = 0.05) in solving the geometric problem due to the interaction between the teaching method (Allosteric Learning Model, the control group) and the spatial perceptions (lower, upper). The study recommended encouraging mathematics teachers to adopt teaching topics in mathematics according to the teaching approach based on the dimensions of the Allosteric Learning Model, conducting introductory workshops for teachers using the Allosteric Learning Model, and training them in building teaching models based on it.
