Background: Diabetic patients are usually more prone to Helicobacter pylori infection is considered as one of the most pathogenic bacteria worldwide. This infection is frequent and severe in those patients who may have defect in their immune system. Objectives: The present study is aimed to determine the prevalence of H. pylori infection among type 2 diabetes mellitus patients in Taiz city-Yemen and to determine the relationship between the prevalence of H. pylori infection among T2DM patients with different risk factors. Methods: This cross-sectional study was conducted on 200 T2DM patients. Blood samples were collected from patients to determine glycosylated hemoglobin (HbA1c), serum was prepared to determine fasting blood sugar (FBS), and stool samples were also collected to detect H. pylori antigen by immunochromatographic assay. Results: The prevalence of H. pylori infection among T2DM patients was 39.5%. There were statistically significant relationships between H. pylori infection and body mass index (BMI), gastrointestinal tract (GIT) symptoms, and glycosylated hemoglobin (HbA1c) among diabetic patients, p= 0.001, p < 0.05, and p= 0.017, respectively. Conclusion: The study confirmed that there was a prevalence of H. pylori infection among T2DM patients. In addition, HbA1c level was increased in diabetics with high BMI. Therefore, the high BMI and HbA1c level are considered as risk factors for H. pylori infection and DM complications. So, this study recommended that diabetics with high BMI should decrease their weight, and chronic H. pylori infection should be managed in glycemic control of T2DM.

Encrypted Text Steganography in Audio Files Using ECC, LSB and Chaotic Maps

2025-08-28T12:25:36+00:00

Steganography ensures secure data transmission by concealing sensitive information within innocuous carrier files, such as audio, to evade detection. This paper proposes a robust steganographic framework that combines Elliptic Curve Cryptography (ECC) for encryption with Least Significant Bit (LSB)-based audio steganography, enhanced by chaotic maps to improve security and unpredictability. The methodology first encrypts the secret data using ECC, leveraging its high security with compact key sizes, and then embeds the ciphertext into audio files via dynamic LSB substitution, guided by chaotic sequences to randomize bit positions. Experimental evaluations demonstrate the scheme’s effectiveness in maintaining audio fidelity (assessed via PSNR and SNR metrics) while ensuring high embedding capacity and robustness against steganalysis. Security analysis confirms resilience to brute-force and entropy-based attacks due to the dual-layer protection of ECC and chaotic randomization. This study presents an innovative approach that comprehensively addresses the core steganographic requirements of imperceptibility, embedding capacity, and resistance to detection, thus providing a reliable framework for clandestine data transmission in security sensitive applications.

Background: About one-half of the world population has been affected with Helicobacter pylori (H. pylori) and it is very prevalent in developing countries. The expanded risk of infection due to precarious hygiene standards, crowded households and incomplete sanitation associated with this portion of the world. H. pylori is known as gram-negative, spiral shaped, flagellated organism uniquely adjust to colonize the gastric mucous layer.

Objective: To determine the relation between H. pylori infection in patients with various of gastrointestinal and respiratory symptoms in Taiz city, Yemen, based on stool and serological diagnostic tests.

Methods: In the present study, a cross-sectional study for a total of 178 patient’s antigen and antibody sample diagnosis for H. pylori were conducted. One hundred thirty-eight outpatients are from hospitals and clinic centers with different gastrointestinal (GI) and respiratory (R) symptoms, and 40 individuals as control (patients without symptoms). The samples were collected during the period of September 2017 to May 2018. Two samples were used to detect H. pylori; the blood sample to detect the presence antibodies (Ab) and stool sample to detect antigens (Ag) of H. pylori. The data analysis was conducted by the SPSS version 24.0.

Results: The current study results showed a statistically significant distribution of H. Pylori infection among the outpatients according to demographic, clinical data, symptoms and diagnostic method. Out of 178 outpatients 65 (37%) male and 113 (63%) females, age ranging from 9 to 63 years. The accompanying symptoms were associated with Gl and respiratory symptoms and infection. The Ag test identified 42 positive cases out of 69 (60.9%; p<0.05) while the Ab test detected 33 positive cases out of 69 (47.8%; p<0.05) patients. Similarly, for respiratory symptoms, the Ag test identified 8 positive cases out of 9 (88.9%; p<0.05), and the Ab test detected 6 positive cases out of 9 (66.7%; p<0.05).

Recycling construction and demolition waste to transform environmental challenges into engineering opportunities and utilizing it as a primary material in concrete

2025-08-28T13:16:47+00:00

Construction and demolition waste presents significant environmental and economic challenges, particularly with increasing quantities resulting from demolition, wars, and natural disasters. These effects are further compounded by the depletion of natural resources required to produce new construction materials and the rising costs associated with waste disposal. However, when properly managed, such waste can be transformed into valuable engineering and economic opportunities.

This study investigates the feasibility of recycling demolished concrete as a substitute material in concrete mixtures to produce acceptable-quality concrete and reduce reliance on conventional raw materials. The research involved testing the properties of recycled coarse aggregate and evaluating its impact on concrete mix performance. Four mixes were prepared with varying replacement ratios of recycled aggregate (30%, 50%, 70%, and 100%) and compared with a reference mix containing 0% recycled aggregate.

The results were generally positive for both fresh and hardened concrete. Mixes with 30%, 50%, and 70% replacement showed satisfactory slump values (2–10 cm), indicating good workability. However, the 100% replacement mix exhibited poor workability due to the high water absorption of recycled aggregate, which also led to a 12.5% reduction in 28-day compressive strength compared to the control mix. In contrast, the 30%, 50%, and 70% mixes showed minor reductions in compressive strength (6.25%, 8.75%, and 9.3%, respectively), suggesting their potential use in structural applications.

This study demonstrates the potential of using recycled aggregate as a partial replacement for natural coarse aggregate in concrete production, providing a sustainable solution for construction waste management while maintaining acceptable performance standards.
