   Infection with Trichomonas vaginalis and its relation to some diseases have lately had much attention.  The objective of this study was to assess the infection rate of T. vaginalis and its relation to pelvic inflammatory diseases, infertility, and vaginosis. The study also assessed some demographic, clinical, and immunological parameters in women infected with T. vaginalis. The study included 160 non-pregnant married women who attended some private clinics and public hospitals in Baghdad from October 2020 to February 2021. All participants had symptoms of vaginal discharge only or vaginal discharge with lower abdominal pain. The participants were divided into an infertility group (n = 61) and fertility group (n = 99). The participant

Twenty five vaginal swabs from outpatients' healthy women were collected from Kamal Al-Samarai Hospital, Baghdad, to isolate and identify of Lactobacillus acidophilus. Three isolates were diagnosed as L. acidophilus which represents 15% of the total number of lactic acid bacterial (LAB) isolates; other LAB types represent 65% (20 isolates).The ability of L. acidophilus to produce surlactin was detected after measuring its biological activity to inhibit the adhesion of biofilm formed by Pseudomonas aeruginosa to surfaces using test tube method. It was found that all isolates were able to produce surlactin but the activity of surlactin was varying in each isolate. Surlactin produced by isolates 1 and 13 was the most effective. Biological appl

We conducted this laboratory study to evaluate the radiation risks in dental materials. We chose zirconium, which is used in the manufacture of artificial teeth, fillings and crowns, from ten different materials that we collected from authorized sales agents in Baghdad and some hospitals. We used the neutron activation analysis method because it is a non-destructive and accurate method that takes a good amount of time. After preparing the samples by grinding and pressing them in moulds, each sample weighing one gram, we placed them on a cross-sectional trace detector with the same dimensions. Then we introduced them to the radiator located in the laboratory of Ibn Al-Haitham College of Education. The advanced nuclear laboratory is based

0.850µm-wavelength 1D Vertical Cavity Surface Emitting Laser (VCSELs have matured as a short-distance optical communication light source that has small threshold currents, high modulation band width, and multimode fibers. In this paper, the design, simulation and analysis of an 850 nm oxide-confined 1DVCSEL have been presented using the Laser MOD tool from R-Soft software. The structure is a cylindrical-shaped design consisting of top and bottom DBRs, a multi-quantum well (MQW) active region, and an oxide aperture for transverse current for optical confinement. The numerical investigation gives rise to the spatial mode profiles, modal gain, threshold current, output power and far-field angle in terms of cavity or oxide aperture

This study investigates radiative proton capture reactions in light nuclei such as [⁹B- ⁷Li, - ⁷Be], which are crucial in stellar nucleosynthesis and energy production. The Woods-Saxon potential model was employed to describe nuclear interactions, and the Schrödinger equation was solved to determine bound and continuum state wave functions accurately. Astrophysical S-factors and reaction cross-sections were calculated at low energies characteristic of stellar environments, accounting for nuclear resonance effects that significantly enhance reaction probabilities. Radiative proton capture reactions, of the form A(p,γ)B, are fundamental processes in nuclear astrophysics. They are the primary mechanism fo

Polymethyl methacrylate (PMMA) is widely used for denture bases but suffers from limited fracture resistance; high impact acrylic, enhanced with butadiene styrene rubber, improves strength. Lasers, particularly the Nd: YAG type, have been used to modify acrylic surfaces, mainly to enhance bonding with soft liners; however, little is known about the effect of Nd: YAG laser treatment on other properties like hardness and color, which are critical for clinical performance and esthetics. The study objective was to evaluate the effect of nanosecond pulsed Nd: YAG laser irradiation with two different hatch values on the hardness and color of high-impact acrylic denture base material. Fifty acrylic samples were made and divided into three group

An electrochemical sensor based on an amino-functionalized iron NH2-MIL-101(Fe) metal-organic framework (MOF)/Pd nanoparticles (NPs) composite-modified screen-printed elec­trode (SPE) is prepared for the simultaneous determination of norepinephrine (NEPI) and acetaminophen (ACP). The NH2-MIL-101(Fe) MOF/Pd NPs/SPE electrochemical sensor shows a significant enhancement in the response peak current of NEPI, as compared to bare SPE. This suggests that the unique features of NH2-MIL-101(Fe) MOF/Pd NPs composite-mo­di­fied SPE improve the electro­catalytic oxidation of NEPI. Such a synergistic effect bet­ween NH2-MIL-101(Fe) MOF and Pd NPs results in a significant enhancement in the res­pon­se, where the MOF's high surface area co

The increasing resistance of bacteria to conventional antibiotics has driven the search for alternative antimicrobial agents, such as metal nanoparticles. Copper oxide nanoparticles exhibit strong antibacterial and antibiofilm properties due to their high surface-to-volume ratio and reactive oxygen species generation. The biosynthesis of nanoparticles (NPs) using microorganisms offers an eco-friendly and cost-effective approach compared to chemical methods. Pseudomonas aeruginosa, a pathogenic bacterium, produces pyocyanin, a redox-active pigment with metal-reducing properties, which can facilitate the synthesis of CuO NPs. Pyocyanin acts as a stabilizing and reducing agent, enabling the formation of NPs with enhanced biocompat

Safe water is a crucial resource for the survival and sustenance of life, and its scarcity is a major cause of water-related ailments, particularly in underdeveloped nations.  The aim of this study was to determine the antibiotic sensitivity pattern of Escherichia coli isolated from the surface waters of the Tigris River and the detection of resistance genes (qnrB, qnrS, parE, and armA) for E. coli. A total of 32 bacterial isolates of E coli were collected for analysis from four distinct sites: S1 Al-Muthana Bridge, S2 Al-Sarrafia Bridge, S3 Al-Senak Bridge, and S4 Al-Jadriyah Bridge. Water samples were collected from November 2023 until July 2024. The isolation of E. coli is perform

     The article studies the integration of artificial neural networks (ANNs) in the phylogenetic analysis of scriptinformatics, focusing on the historical evolution of Arabic, Aramaic, and Middle Iranian scripts. By treating scripts as taxa, pattern systems are exploited to delineate evolutionary trajectories, utilizing an optimised feature selection method and neural network architectures fitnet and feedforwardnet. The presented approach leverages publicly accessible genetic sequence datasets and applies comprehensive preprocessing, including a novel feature extraction process, normalisation, and cross-validation, to predict phylogenetic tree lengths. The results indicate a superior performance of the feedforward neural network, pa

In recent years, there has been a significant urbanization of the world, including in Iraq, particularly in Baghdad. This has led to an increase in pollutants and greenhouse gas (GHG) emissions, particularly carbon dioxide (CO₂). Therefore, it was necessary to find sustainable environmental solutions to reduce these gases, one of which is the biological sequestration of CO₂ using trees. Therefore, this study aimed to calculate CO₂ sequestration from trees using field data and biological methods for the Yamama City residential complex in Baghdad. The results showed that the complex's trees, numbering 3788, contributed to sequestering 197039.2 kg/year. This amount varies between four types (Conocarpus,

Air pollution is considered one of the most dangerous types of pollution because of the problems and risks it causes to living organisms on the surface of the Earth. This paper studied the emission of air pollutants (nitrogen dioxide, NO₂, sulfur dioxide, SO₂, and particulate matter PM_2.5) in the city center of Nasiriyah. The data were taken from the European Mediterranean Weather Forecast (ECMWF) during the year (2022). The pollutant roses were plotted, which show the most pollutant source from the northwest direction of the electric power plant in the city and another source from the south (Nasiriyah refinery and Saba oil field). The daily rates of NO₂, SO₂ and PM_2.5 con

In this study, the link between bacterial infection and BCL9 gene methylation was examined, which is crucial to cancer formation. Also, it examined patients' gene methylation levels for stomach ulcers, gastritis [acute and chronic], and duodenal ulcers and cancer risk.  Using MS-RT-PCR, BCL-9 methylation was associated more strongly with clinical variables. Substantial differences in BCL-9 methylation between patients and controls (median 1.368, Interquartile Range [0.912-1.468] vs. 1.001, [0.861-1.211], p<0.05). Interestingly, males had substantially greater BCL-9 methylation levels than females (median 1.186, Interquartile Range [1.139-1.308] vs. 0.986, Interquartile Range [0.875-1.150], p<0.05). A sig

     This work concerns with the study of the continuous classical quaternary boundary optimal control problem or, for brief quaternary boundary optimal control problem (QBOCP) controlling by quaternary nonlinear hyperbolic system (QNLHS).  The theorem for existence a unique quaternary state vector solution (QSVS) for the weak formulation (WFO) of the QNLHS is proved in an infinite dimensional space via the method of Galerkin, and the help of the Aubin’s Theorem with given a continuous boundary control quaternary vector (CBCQV). The continuity of the operator of Lipschitz between the quaternary state vector and the conforming quaternary boundary control vector is demonstrated. The existence theorem of a continuous boundary optimal

     The increase in the amount of biometric data in databases has caused problems for efficient data retrieval and management. Biometric databases face challenges primarily due to the high dimensional nature of biometric features, such as fingerprints, facial recognition data, and iris scans, leading to time consumption in retrieval and matching as well as computationally intensive, and inefficiencies that can hinder real-time applications, especially when using multiple biometric traits. To address these issues, this paper presents a mechanism for searching three-dimensional biometric databases based on inverted files specifically tailored to handle biometric data. As well as designing a 3D database to store data. This method was a

This study was Conceived to choose an appropriate isolate of Lactobacillus sp. To use it as a probiotic in chewing gum for the Prophylaxis of gingivitis. Due to the above reason, 20 Lactobacillus isolates were collected from various sources and then primarily enrolled in a screening program to assess their activities of antagonism against two oral pathogens, Streptococcus pluranimalium and Staphylococcus aureus. Twenty Lactobacillus isolates were selected from the initial screening based on their efficacy to suppress the growth of the two chosen indicators which was then followed by another step of secondary screening to detect their production of the high amount of bacteriocin and their effec

Programmed cell death protein 1 (PD-1) may be in a position to interact hydrophobically with the spike glycoprotein or its epitopes of SARS-CoV-2, which, in addition to the neuroinvasive capability it possesses, triggers hyperactivation of the Program Death Ligand1.  A case-control study (67 COVID-19 patients and 23 healthy controls) was conducted to detect the role of soluble Program Death-Ligand1 (sPDL-1). The sPD-L1 serum concentrations were measured with an ELISA kit, while the SARS-CoV-2 infection was determined earlier via a real-time PCR evaluation kit. The findings demonstrated that median sPD-L1 levels in patients were substantially more significant compared to healthy controls (1349 vs. 737.8 pg/ml; p < 0.
