Background: Raoultella planticola is a developing pathogen that can infect both humans and animals. Raoultella spp. commonly colonize the gastrointestinal and upper respiratory systems. It usually causes pneumonia, bile tract infections, and bacteremia. Aim: In this study, the anticancer activity of an isolated brown pigment of a Raoultella planticola isolate was tested in vitro. Methods: The laboratory examination included culturing in brain-heart infusion broth, conducting biochemical tests, using the automatic VITEK2 Compact for bacterial isolate identification, performing the MTT assay to evaluate the cytotoxic effect on both the mammary cancer cell line (AMN3) and normal rat fibroblast (REF), and utilizing enzyme-linked immunosorbent assay to measure cytokine levels. Results: R. planticola was found in cow nasal swabs with respiratory problems. The extracted pigment had a significant cytotoxic effect (decreased cell viability) at doses of 2067.5 μg/mL (p < 0.0001 and 0.0001, respectively) and 1033.5 μg/mL (p < 0.0001 and 0.003, respectively). However, the lowest dose (516.875 μg/mL, p > 0.43 and p > 0.18) could not inhibit the growth of malignant or healthy cells. The first and second highest pigment concentrations reduce IL-1β and TNF-α and increase Fas in the AMN3 cell supernatant (p < 0.05). In the AMN3 cell supernatant, the lowest concentration significantly increased IL-1β levels (p < 0.0472) and Fas levels (p < 0.0146), but did not affect TNF-α levels (p < 0.1274). Pigment concentrations at the first and second highest levels significantly reduced IL-1β and TNF-α levels in the REF cell supernatant (p < 0.05), whereas the lowest concentration did not. All pigment doses did not affect the Fas levels in the REF cell supernatant (p > 0.05). Conclusion: In a concentration-dependent manner, the extracted pigment may exert cytotoxic effects and impact cytokine secretion levels in cancerous and normal cell types.
Two field experiments were conducted during the spring seasons of 2000,2001.The aim was to study the effect of hardening to drought tolerance on moisture percentage in root and stem of sunflower plant during growth stages . Asplit-split plots design was used with three replications.The main plots included irrigation treatments:irrigation to100%(full irrigation),75and50%of available soil water.The sub plots were the cultivars Euroflor and Flame.The sub-sub plots represented four seed soaking treatments :Control(unsoaked),soaking in water ,Paclobutrazol solution(250ppm),and Pix solution(500ppm). The soaking continued for 24 hours then seeds were dried at room temperature until they regained their original weight. Amount of water

This work revealed the spherical aromaticity of some inorganic E4 cages and their protonated E4H+ ions (E=N, P, As, Sb, and Bi). For this purpose, we employed several evaluations like (0D-1D) nucleus independent chemical shift (NICS), multidimensional (2D-3D) off-nucleus isotropic shielding σiso(r), and natural bond orbital (NBO) analysis. The magnetic calculations involved gauge-including atomic orbitals (GIAO) with two density functionals B3LYP and WB97XD, and basis sets of Jorge-ATZP, 6-311+G(d,p), and Lanl2DZp. The Jorge-ATZP basis set showed the best consistency. Our findings disclosed non-classical aromatic characters in the above molecules, which decreased from N to Bi cages. Also, the results showed more aromaticity in E4 than E4H+
... Show MoreObjectives: To study the spectrum and classification of ATP7B variants in Iraqi children with Wilson disease by direct gene sequencing with clinical correlation. Methods: Fifty-five unrelated children with a clinical diagnosis of Wilson disease (WD) were recruited. Deoxyribonucleic acid was extracted from peripheral blood samples, and variants in the ATP7B gene were identified using next-generation sequencing. Results: Seventy-six deleterious variants were detected in 97 out of 110 alleles of the ATP7B gene. Thirty (54.5%) patients had 2 disease-causing variants (15 homozygous and 15 compound heterozygous). Twelve (21.8%) patients had one disease-causing variant and one variant of uncertain significance (VUS) with potential pathogenicity. T
... Show MoreThe concept of -closedness, a kind of covering property for topological spaces, has already been studied with meticulous care from different angles and via different approaches. In this paper, we continue the said investigation in terms of a different concept viz. grills. The deliberations in the article include certain characterizations and a few necessary conditions for the -closedness of a space, the latter conditions are also shown to be equivalent to -closedness in a - almost regular space. All these and the associated discussions and results are done with grills as the prime supporting tool.
