Synergistic Antibacterial and Anticancer Effects of a Biohybrid Composed of Zinc Oxide Nanoparticles and <i>Streptococcus Salivarius</i> Bacteriocin
...Show More Authors
ABSTRACT<p> Antimicrobial therapies are desperately needed since the threat posed by multidrug‐resistant (MDR) bacteria only grows. Bacteriocins produced by <italic>Streptococcus salivarius</italic> possess promising antibacterial properties, yet their practical application is hindered by low production yield and limited stability. Here, we report the green synthesis of a novel biohybrid by conjugating purified <italic>S. salivarius</italic> bacteriocins with zinc oxide nanoparticles (ZnONPs), aiming to enhance bacteriocin stability and antimicrobial efficacy. The successful creation of well‐dispersed nanohybrids was validated by thorough characterization using x‐ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM), exhibiting predominantly cubic and spherical morphologies with sizes ranging from 8 to 68 nm. The ZnONPs–bacteriocin nanohybrids demonstrated pronounced antibacterial activity against both Gram‐positive and Gram‐negative MDR pathogens, as evidenced by significant inhibition zones, and low values for the minimum bactericidal concentration (MBC) and minimum inhibitory concentration (MIC). In vitro cytotoxicity, assays revealed a dose‐dependent reduction in the viability of both cancerous (A375) and normal (HdFn) cell lines. The nanohybrid displayed greater cytotoxicity toward A375 cells (IC <sub>50</sub> = 121.7 µg/mL) than HdFn cells (IC <sub>50</sub> = 161.6 µg/mL), indicating a degree of selectivity. Collectively, our results demonstrate that green‐synthesized ZnONPs–bacteriocin biohybrids are eco‐friendly and exhibit potent, broad‐spectrum antimicrobial and selective cytotoxic activities, suggesting their significant potential for biomedical applications targeting resistant bacterial infections and malignant cells. </p>

The Influence of NMI against Modularity in Community Detection Problem: A Case Study for Unsigned and Signed Networks
...Show More Authors

Community detection is useful for better understanding the structure of complex networks. It aids in the extraction of the required information from such networks and has a vital role in different fields that range from healthcare to regional geography, economics, human interactions, and mobility. The method for detecting the structure of communities involves the partitioning of complex networks into groups of nodes, with extensive connections within community and sparse connections with other communities. In the literature, two main measures, namely the Modularity (Q) and Normalized Mutual Information (NMI) have been used for evaluating the validation and quality of the detected community structures. Although many optimization algo

A Comparative Study of Various Intelligent Optimization Algorithms Based on Path Planning and Neural Controller for Mobile Robot
...Show More Authors

In this paper, a cognitive system based on a nonlinear neural controller and intelligent algorithm that will guide an autonomous mobile robot during continuous path-tracking and navigate over solid obstacles with avoidance was proposed. The goal of the proposed structure is to plan and track the reference path equation for the autonomous mobile robot in the mining environment to avoid the obstacles and reach to the target position by using intelligent optimization algorithms. Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) Algorithms are used to finding the solutions of the mobile robot navigation problems in the mine by searching the optimal paths and finding the reference path equation of the optimal

Subsurface Water Retention a Technology for Increasing the Field Use Efficiency and Water Saving Values of Cucumber Plant
...Show More Authors

The technology of subsurface soil water retention (SWRT) uses a polyethylene trough that is fixed under the root zone of the plant. It is a modern technology to increase the values of water use efficiency, plant productivity and saving irrigation water by applying as little irrigation water as possible. This study work aims at improving the crop yield and water use efficiency of a cucumber plant with less applied irrigation water by installing membrane trough below the soil surface. The field experiment was conducted in the Hawr Rajab District of Baghdad Governorate in Winter 2018 for testing various trickle irrigation systems. Two agricultural treatment plots were utilized in a greenhouse for the comparison. Plot T1 has used a subsurface t

A First Record and Developmental Stages of an Exotic Species Cochlicellabarbara (Linnaeus, 1758) (Gastropoda-Cochicellidae) in Iraq Baghdad
...Show More Authors

The aim of this study is to highlight this species of gastropoda Cochlicellabarbara( Linnaeus, 1758), which is recorded for the first time in Iraq, which is an exotic animal in this country. It is a terrestrial Molluscan, the study for three months (February, March and April) 2017. In garden houses in Baghdad Al-Karkh, we studied the development stages from the egg to the adult, they lay a hundred of eggs in about (15-20) eggs in each gelatinous sac, the shell with 7 whorls and about 10 mm in length.

Numerical Simulation of Unsaturated Soil Water Flow from a Trickle Point System, Considering Evaporation and Root Water Uptake
...Show More Authors

This research was carried out to study the effect of plants on the wetted area for two soil types in Iraq and predict an equation to determine the wetted radius and depth for two different soil types cultivated with different types of plants, the wetting patterns for the soils were predicted at every thirty minute for a total irrigation time equal to 3 hr. Five defferent discharges of emitter and five initial volumetric soil moisture contents were used ranged between field capacity and wilting point were utilized to simulate the wetting patterns. The simulation of the water flow from a single point emitter was completed by utilized HYDRUS-2D/3D software, version 2.05. Two methods were used in developing equations to predict the domains o

Background: Diabetes mellitus (DM) could be regarded as a set of chronic metabolic disorders which have a common aspect of hyperglycemia. The resistance in the peripheral actions of insulin or impaired insulin secretion could be the reason  hepcidin which is a peptide hormone derived from liver, in systemic iron homeostasis is an essential regulator, and its lopsided production participates in the pathogenesis of iron disorders in spectrum.
