Abstract

This study sought to understand the impact of an alcoholic extract of Artemisia annua on kidney function in experimental diabetic rats. For this study, fifty adult male albino rats were randomly assigned to one of five groups: G1 received unrestricted access to food and water. G2: To induce diabetes, a single intravenous injection of STZ (60 mg/kg) is administered. The third group undergoes insulin subcutaneous injections for four weeks after each STZ injection. The fourth group takes Artemisia annua extract orally (by gavage) at a dose of 75 mg/kg for four weeks following each STZ injection. The fifth group takes insulin subcutaneously (by gavage) and Artemisia annua extracts orally (70 mg/kg) for four weeks following each STZ injection. We took blood samples from the orbital sinus to estimate creatinine, urea, uric acid, SOD, GPX, and CAT in the serum. We extracted the kidneys for histopathological investigation after slaughtering the animals. The current results demonstrated a significant reduction in all kidney functions, including creatinine and urea, as well as uric acid, following treatment with insulin, Artemisia annua extract, or a combination of insulin and extract. According to these results, the amount of SOD in G3, G4, and G5 is significantly higher than in G1 and G2. However, there were no significant differences between the groups in the amounts of GPX and CAT. The histopathological results of the kidney in groups G1 and G4 revealed a normal histological appearance. Kidneys of G2 exhibit glomerular atrophy and interstitial hemorrhage. G3 displayed tubular epithelial degeneration, necrosis, mesangial cell hyperplasia, glomerular atrophy, and inflammatory cell infiltration. The kidney of G5 displays blood vessel dilatation, congestion, glomerular atrophy, and acute swelling of epithelial cells. In conclusion, the alcoholic extract of Artemisia annua reduces the kidney function in experimental diabetic rats and can alleviate the histological damage of diabetes on renal tissue.

Abstract

Prior research has assessed the correlations between the likelihood of acquiring diabetes mellitus and the polymorphism in the cholesterol ester transfer protein (LIPASE GENE). Chronic hyperglycemia and abnormalities in the metabolism of carbohydrates, fats, and proteins due to deficiencies in insulin production, action, or both are characteristics of the metabolic condition known as diabetes mellitus (DM), which has several etiologies. However, the conclusions are still up for debate. This study sought to determine whether lipid profile abnormalities in Iraqi diabetic patients were associated with the LIPASE GENE. Methods, To shed light on the relationships between the LIPASE GENE TaqIB polymorphism, HDL-C levels, and diabetes mellitus, we performed a meta-analysis of the literature. Findings: This study included 160 Iraqi participants, 90 of whom had diabetes mellitus, and 70 of whom served as controls. Table 1 displays the population study's blood lipid data. TC, TG, LDL-C, and VLDL-C were all considerably greater (P<0.0001) in the patient group than in the control group, with the exception of HDL-C, which was lower (P<0.0001). In this study, there were more men (75.55%) than women (24.4%) with type 2 diabetes. The large percentage of men in this research may result from the demographics of the hospital's patients, who tend to seek medical care more frequently than women to have more free time because most of them are retired. Included in the correlation between HDL-C concentration and lipase polymorphism. The LIPASE GENE gene has been shown to have a variety of single nucleotide polymorphisms. The influence of the rs708272 (g.5454G>A) polymorphism on HDL-C focus has been explained. This study aimed to evaluate the LIPASE gene site polymorphism and its effect on blood lipids in Iraqi patients with lipid problems. Since a few evaluations listed the LIPASE GENE polymorphism's association with the HDL level we decided to use it because we couldn't locate any Iraqi studies that addressed this polymorphism.

Abstract

Acinetobacter baumannii is a Gram-negative, pathogenic bacterium associated with multidrug-resistant hospital infections, making it a prime target for research into alternative treatments the work aimed to study the antibacterial properties of alcoholic and aqueous extracts of thyme. One hundread blood samples were collected from patients admitted to the Intensive Care Unit (ICU) at Sharqat General Hospital for the period from 1/9/2024 to 30/3/2025. Patient information was recorded, including patient name, age, and type of infection related to the patient’s condition. Bacterial isolates were diagnosed based on phenotypic characteristics of bacteria, colony growth, and basic biochemical tests. The antibacterial activity of the alcoholic and aqueous extracts was evaluated by well diffusion method at concentrations of (5, 10, 25, 50, and 100) µg/ml. The results of testing the effectiveness of the alcoholic and aqueous extracts of thyme against Acinetobacter baumannii bacteria showed that the alcoholic extract recorded higher activity at all concentrations compared to the aqueous extract. At the lowest concentration (5 µg/mL), the diameter of the inhibition zone for the alcoholic extract was 4.5 ± 0.5 mm, while it was 3.2 ± 0.4 mm for the aqueous extract. When the concentration was increased to 10 µg/mL, the activity increased to 7.2 ± 0.7 mm for the alcoholic extract versus 6.3 ± 0.6 mm for the aqueous extract. At a concentration of 25 µg/mL, the inhibition zone reached 10.2 ± 0.6 mm for the alcoholic extract and 9.8 ± 0.7 mm for the aqueous extract, which are slight differences but continue to favor the alcoholic extract. At a concentration of 50 µg/mL, the values were 15.2 ± 0.7 mm for the alcoholic extract and 13.5 ± 0.8 mm for the aqueous extract. Finally, at the highest tested concentration of 100 µg/mL, inhibition reached its maximum levels, recording 19.3 ± 0.8 mm for the alcoholic extract and 17.2 ± 0.9 mm for the aqueous extract The alcoholic extract showed higher inhibitory activity than the aqueous extract against A. baumannii at all tested concentrations.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan karakteristik morfoogi tanaman Lemon Suanggi (Citrus limon) yang tumbuh di wilayah pesisir Teluk Tomini. Penelitian ini menggunakan metode deskriptif eksploratif, dengan aksesi yang dikumpulkan dari lima kabupaten di dua provinsi, yaitu di Gorontalo dan Sulawesi Tengah. Data Morfologi diperoleh melalui pengamatan langsung dari batang, daun, buah, dan biji, mengacu pada Deskriptor untuk Jeruk oleh Plant Genetic Resoutces Institue (1999). Temuan menunjukkan bahwa ada delapan aksesi Lemon Suanggi (Citrus limon) dengan variasi karakteristik morfologi yang nyata. Perbedaan ini diamati pada ukuran dan bentuk daun, ketebalan kulit buah, jumlah biji, dan tekstur permukaan buah. Variasi morfologi ini dipengaruhi oleh kombinasi faktor genetik dan kondisi lingkungan seperti suhu, kelembaban, dan curah hujan di wilayah pesisir. Temuan ini menunjukkan keragaman yang signifikan yang memiliki potensi besar utuk menjadi landasan penting bagi konservasi, pemuliaan, dan pengembangan sumber data genetik tanaman lokal di masa depan.

Abstract

Penelitian ini bertujuan untuk mengevaluasi potensi enzim kitinase yang dihasilkan oleh bakteri kitinolitik dari limbah kulit udang sebagai biopestisida hayati terhadap larva lalat buah (Drosophila sp.). Penelitian dilakukan melalui tiga tahap, yaitu isolasi dan identifikasi bakteri kitinolitik, pengujian aktivitas enzim kitinase, serta uji efektivitas enzim terhadap kematian larva. Sampel kulit udang putih (Penaeus merguiensis) digunakan sebagai sumber isolat alami yang kaya akan kitin. Hasil isolasi menghasilkan tiga jenis bakteri, yaitu Vibrio sp., Bacillus sp., dan Pseudomonas sp., yang semuanya menunjukkan aktivitas kitinolitik dengan terbentuknya zona bening pada media kitin. Identifikasi morfologi dan biokimia memperkuat hasil tersebut melalui uji pewarnaan Gram, motilitas, serta serangkaian uji fermentasi gula dan TSIA. Uji efektivitas menunjukkan bahwa filtrat enzim kitinase dengan konsentrasi di atas 50% menyebabkan kematian larva secara signifikan, dengan waktu tercepat terjadi pada konsentrasi 100%, yaitu 10 menit 15 detik, sedangkan pada konsentrasi di bawah 40% tidak menunjukkan efek mematikan. Aktivitas enzim kitinase bekerja dengan mendegradasi komponen kitin pada eksoskeleton larva, menyebabkan kerusakan struktural dan gangguan fisiologis yang berujung pada kematian. Hasil penelitian ini menegaskan bahwa enzim kitinase memiliki potensi besar sebagai agen biopestisida ramah lingkungan yang efektif, ekonomis, dan berkelanjutan. Selain itu, pemanfaatan limbah kulit udang sebagai sumber bioteknologi terapan tidak hanya memberikan solusi terhadap permasalahan limbah industri perikanan, tetapi juga mendukung prinsip ekonomi sirkular, inovasi hijau, serta penerapan pertanian hortikultura yang lebih aman bagi manusia, ekosistem, dan keberlanjutan lingkungan jangka panjang.
