Introduction: A systematic library of Gal4/UAS-regulated transgenes has proven to be a powerful genetic system for identifying genes and defining pathways in development. This system offers valuable insights that highlight the evolutionary conservation between animals and humans. Objectives: The objective of this study was to clone, express, and characterize the UbiA gene. The research presents a highly effective method for cloning genes, using the UbiA-pcDNA3 gene as a model for mammalian cloning. These genes were then integrated into the PUAST vector of Drosophila, an expression vector and eukaryotic cell system commonly used for producing recombinant proteins. Materials and Methods: UbiA was isolated from human cells, and complementary DNA was synthesized. An oligonucleotide primer pair was designed based on the UbiA gene sequence, incorporating XhoI and Xbal restriction sites at the 5´ end of the forward and reverse primers, respectively. The UbiA gene was then amplified by PCR, cloned into the pcDNA3 plasmid, and the resulting recombinant plasmid was sequenced. Subsequently, the gene was sub cloned into the PUAST vector and expressed in S2 cells as a eukaryotic cell system. Protein determination and verification were conducted through western blotting techniques. Results: Confirmation of UbiA gene cloning into the PUAST vector was achieved through colony-PCR and digestion by enzymes. Cloning and sub cloning techniques validated by enzymatic digestion, along with gene sequencing. The identity between cloned UbiA gene and the identical gene exhibited 99%. We revealed a singular band purified protein through western blotting with 60 kDa size. Conclusion: More protein synthesis of the UbiA gene can be achieved by using the eukaryotic expression system provided by the PUAST vector. This technique has been proven to be a suitable platform and can be instrumental in various applications such as therapeutics, pharmacology, and vaccine development.
This work reports the electrochemical fabrication of thin films comprising polyaniline nanofibers (PANI) in conjunction with graphene oxide (GO) and reduced graphene oxide (rGO) on ITO substrate, along with examining the electrochemical properties, with a focus on the influence of the substrate and electrolyte in the electrodeposition methods. The study explores the electrochemical characteristics of these thin films and establishes a flexible framework for their application in diverse sectors such as sensors, supercapacitors, and electronic devices. It analyzes the impact of the substrate and electrolyte in electrodeposition techniques. The effects were studied using techniques such as cyclic voltammetry and chronoamperometry. The fabrication process of PANI/GO and PANI/rGO thin films involved the integration of rGO within PANI via electropolymerization, conducted under sulfuric acid. GO was synthesized by modifying the well-known Hummers’ method and characterized by X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). SEM showed the diameters of the formed PANI were between 40 and 150 nm, which helped to intertwine the rGO nanosheets with PANI nanofibers to form thin films. The electrochemical behavior of the PANI/rGO thin films was examined using cyclic voltammetry (CV) and chronoamperometry in different electrolytes, including sulfuric acid (H₂SO₄) and potassium nitrate (KNO₃). The CV profiles exhibited distinct oxidation and reduction peaks, with variations in the voltammogram morphology attributed to the nature of the electrolyte and the substrate employed during the electrodeposition process. These results highlight the critical role of both the substrate and electrolyte in governing the electrochemical performance of PANI/rGO thin films. The findings from this study demonstrate a versatile approach for the fabrication of PANI/graphene-based thin films with tunable electrochemical properties, and such a strategy has great application to fabricating other thin film composites for supercapacitors or other control source frameworks requiring enhanced charge storage and electrochemical responsiveness.
Objectives Type 2 diabetes mellitus (T2DM) is a persistent metabolic illness causing elevated glucose levels due to insulin resistance. Social media has been found to positively impact diabetes management by boosting motivation, adherence, emotional support, and sharing evidence-based information, thereby enhancing patients’ glycemic control efforts and achieving HbA1c targets. Primarily to examine the influence of social media within a random sample Iraqi population of T2DM patients on the control of diabetes, as measured by HbA1c levels. Methods A multicentric cross-sectional study involves patients diagnosed with T2DM recruited between December 30, 2019 and November 8, 2023. Patients diagnosed with T2DM, who visited the outpatient clinic at least twice during the study period, were included. The sample size comprised 2921 patients. Various social media platforms available including, Facebook, WhatsApp, Instagram, Telegram, X (formerly known as Twitter), and Viber, were reported. Results The study involves 2921 participants with a mean age of 53.3 years, 56% of them successfully reached their HbA1c target within a mean of 18.17 months. A significant correlation was found between achieving the target and using social media (P = .0001), with a shorter average duration among social media users compared to non-users. A family history of diabetes also significantly correlated with achieving the desired outcome, suggesting a probable positive correlation (P = .019). Conclusion The study reveals a significant association between social media usage and glycemic control, introducing the importance of technology-based interventions in enhancing diabetes self-management, highlighting the relationships between social media engagement and HbA1c target achievement.
In this work, a hybrid radial‐axial (HRA) system is used to store thermal energy in a packed bed. The heat transfer fluid (HTF) is delivered via a perforated radial pipe placed at the center of the packed bed along the axial length. Hot fluid flows from the center toward the wall through the holes (like other radial systems), but then leaves via the traditional axial flow exit, creating the HRA flow configuration. A computational fluid dynamics (CFD) model is used to analyze the thermal performance of the packed bed during the charging process utilizing the new HRA system. Alumina beads of 6 mm were filler materials and air was HTF with inlet temperature of 75°C for proof of concept. The present paper focuses on two aims: (1) utilizing CFD models to analyze flow and temperature profiles in the packed bed; (2) comparing the model results to experimental results published in a previous HRA flow study and to traditional axial flow. Two HRA configurations were considered based on previous experimental designs, one with uniform holes in the central pipe (R1) and one with gradients in the hole sizes to promote even flow from the central pipe into the bed (R2). The numerical results agree with the experimental results in both cases. The HRA system performance depends on the flow profile created by the hole designs, and it can perform better than the axial flow depending on the design of the radial pipe. Design R2, which promotes even flow from the central pipe into the bed, has higher charging efficiency than standard axial flow methods. For HRA design R2 at 0.0048 m³/s (7 SCFM, standard cubic feet per minute), numerical results for charging efficiency were 75.5% versus 73.8% for traditional axial flow. For HRA design R2 at 0.0061 m³/s (9 SCFM), numerical charging efficiency was 80.5% versus 78.1% for traditional axial flow. These results are consistent with experimental data.

This study is aimed at fabricating composite biocompatible coatings of Alginate (Alg) and Chitosan (CS) on a stainless steel (grade 316L) substrate, reinforced with several percent nanoparticle additives, Using a dip coating method. The research used Fourier Transform Infrared (FTIR), field emission scanning electron microscopy (FESEM), and Atomic force microscopy (AFM) to explore surface roughness, size dispersion, and surface topography. The introduction of nanoparticles enhanced the wettability of the CS/Alg coatings. Notably, nanoparticle coatings with TiO 2 , Nb 2 O 5 , and biotin showed exceptional wettability due to the hydrophilic qualities of the matrix and reinforcements. This was corroborated by contact angle measurements, which confirmed the hydrophilic nature of the chitosan-alginate blend. The FTIR results highlighted the noticeable compatibility between CS-Alg and (TiO 2 , Nb 2 O 5 , and biotin) nanoparticles. No discernible alterations in the wavelengths were observed. Employing biotin-TiO 2 -Nb 2 O 5 , the FESEM showed that the biocompatible coating films were uniform and devoid of cracks on the 316L stainless steel substrate. The matrix + TiO 2 , matrix + Nb 2 O 5 , matrix + TiO 2 + Nb 2 O 5 , and matrix + TiO 2 + Nb 2 O 5 + biotin-coated 316L stainless steel showed roughness data of 4.14, 5.28, 7.04, and 8.02 nm, accordingly, in contrast with the neat chitosan/alginate coating, which displays 2.67 nm, suggesting the significant impact of biotin and oxides on surface topography. These findings underscore the potential of the developed nanoparticle coatings for orthopedic applications, with enhanced wettability and biocompatibility. Biocompatible coatings emerging from this research are promising for advancing orthopedic and biomedical devices as they are used in scientific studies because of their biocompatibility with human tissues.
The article is dedicated to an urgent problem today; Energy problems are one of the most important global problems of our time and directly affect many countries. Insufficient electricity production and its high cost hinder not only the establishment of industry and manufacturing industries, but also social development. The energy sector in Iraq suffers from a severe shortage of energy supplies with the continuous increase in demand for electrical energy consumption for domestic, industrial and commercial purposes. Therefore, there has been an urgent need to benefit from renewable energy resources, including solar energy, as it is quick to install compared to traditional power plants that require long periods of time, in addition to the environmental damage caused by the use of fossil fuels. The purpose of this work is to increase the efficiency of the energy complex using photovoltaic. To achieve this goal, it is necessary to analyze the operating modes of a photovoltaic system and study various modeling methods and experimental models for a photovoltaic system. The results appear that Iraq has the high intensive solar irradiation in the world during the year that lead to ability high annual generation energy from PV system and for 25 year through the life cycle that net power generation gradually declines slightly, without high affecting production efficiency. The practical value of the research lies in the improved electrical circuit of the photovoltaic generating system, its control elements, increased energy generation efficiency. This significantly increases the efficiency of the production of renewable energy systems. In addition to that, the theoretical significance of the study lies in the use of mathematical programs for modeling the operating modes of solar power generation systems, which significantly improve the operating parameters of control units and auxiliary systems and increase the production of electric energy.
Introduction: Cholelithiasis and related treatments are associated with several gastrointestinal cancers. Thus, the present systematic review and meta-analysis aimed to investigate the relationship between cholelithiasis and cholecystectomy with the risk of liver cancer. Materials and Methods: The present study is a systematic review and meta-analysis conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We performed a search on the databases of Web of Science, Cochrane, ProQuest, PubMed, and Google Scholar until January 21, 2024. Moreover, the statistical analysis was performed using the STATA 14, and the significance level was set at P<0.05. Results: The present meta-analysis included 15 studies with a total sample size of 1426704 participants. According to our results, a significant association between cholelithiasis and liver cancer (OR: 1.76, 95% CI: 1.52, 2.03), as well as cholecystectomy and liver cancer (OR: 1.55, 95% CI: 1.29, 1.87) were detected.

The antimicrobial activity of crude and purified L-glutaminase (EC 3.5.1.2), obtained from Lactobacillus gasseri, was evaluated against multidrug-resistant Pseudomonas aeruginosa in the in vivo vaginosis condition. The Lglutaminase possessed significant antimicrobial and anti-biofilm formation activity against multi-drug resistance P. aeruginosa, which were confirmed in the BALBc rat vaginosis model, together with its effects on the immunological and histopathological aspects. The untreated animals showed heavy vaginitis, characterized by subepithelial edema and infiltration of mononuclear leukocytes, perivascular heavy inflammatory cells infiltration in the vaginal tissue, and moderate stromal edema. However, the L-glutaminase treatment exhibited no changes in vaginal tissue structure with normal appearance of the epithelium and lamina propria with marked repair of the vaginal section when compared with normal, uninfected, control group A. The immunomodulatory actions of the L-glutaminase were confirmed by observance of higher concentrations of tumor necrosis factor-γ (TNF-γ), and interleukin − 12 (IL-12) in treated animals, while the interleukin-10 (IL-10) was higher in the infected, untreated animals’ sera samples. Therefore, the L-glutaminase showed corrective and healing actions, which were observed through histopathological observations of the vaginal tissue. The investigations led to imply that L-glutaminase may have the potential to be an effective antimicrobial agent for preventing and inhibiting bacterial growth, as well as inhibiting the biofilm formation in the P. aeruginosa-originated vaginosis. The observations may be of promising value for future clinical use.
BACKGROUND Clove oil has a wide range of therapeutic and pharmaceutical applications. It is also used in the manufacture of pesticides and antifungals, as well as many advantages. The study aims to improve the properties of essential oils, especially clove oil, and make them more stable by the design of delivery systems (nanoemulsions and biopolymer nanoparticles). METHODS Clove oil was mixed with water in the presence of tween-20 as a polysorbate-type nonionic surfactant, and then carboxymethyl cellulose was added with different ratios of glycerin as a cross-linking agent. The formation of the clove nanogel was tested by spectrophotometric assay 2.2.2 Fourier transform infrared spectroscopy (FT-IR), Proton Nuclear Magnetic Resonance Spectroscopy ( ¹ H-NMR), dynamic light scattering (DLS), and morphology method field emission scanning electron microscopy (FESEM), also the rate of clove oil release during different periods, and hemolytic and antioxidant activity were tested. RESULTS The nanoparticles were demonstrated by DLS and FESEM. The polydispersity index value was 0.279, indicating good monodispersity and good stability, while higher release values were obtained when glycerol was not present as a cross-linker. In addition to the higher antioxidant, values of the clove oil nano emulsion (CNE) have a maximum inhibition of 65% at a concentration of 100 μg/mL, whereas clove nano-gel (CNG) at the same concentration exhibited 59.2% inhibition. The calculated IC50 values of CNG and CNE were 6.58 and 3.25 μg/mL, respectively. CONCLUSION The study proved through the results obtained that nanocomposites help stabilize components, especially volatile oil, which increases their effectiveness.
The lack of mechanical and antibacterial characteristics of most dental resins impedes their broader applications in dentistry. Therefore, this study aimed to enhance biocompatibility and mechanical and antibacterial features of bioepoxy (BE) to be used in dentistry. The properties of BE were assessed prior to and after reinforcing with several loading of nanoalumina (Al2O3)/nanosilver (AgNPs) particles. The mechanical characteristics were evaluated using three-point bending and Izod impact tests. The morphologies and surface roughness of pristine BE and nanoalumina/nanosilver-reinforced BE composites were observed by scanning electron microscopy (SEM) and atomic force microscopy (AFM), respectively. The influence of these additives on the BE antibacterial properties were evaluated using the agar diffusion approach. The flexural strengths of the modified BE composites with nanoalumina/nanosilver particles were higher than those for additive-free BE, and their values were considerably dependent on filler loading. The impact strength and flexural strength of composite materials were greater at hybrid reinforcement loading of 2 wt%. At such ratio, an increase of approximately 33.8% was obtained in the flexural strength compared with that of blank BE. On the other hand, the incorporation of higher proportions of nanoparticles led to a decrease in overall properties of composites, yet they were higher than that of additive-free BE. The flexural strength for the composite containing 0.5 wt% AgNPs and 3.5 wt% Al2O3 was higher than the value stated for the nanoparticles-free BE by 18.7%. Furthermore, the composite comprising 0.5 wt% of each of the nanoparticles had a great ability to alleviate the spreading of Staphylococcus aureus and Escherichia coli when compared with the resin and composites with other formula. For instance, the diameter of inhibition zone (DIZ) against Staphylococcus aureus of the aforementioned composite increased about 16% than that of additive-free BE. All these features make this composite system a promising candidate in biomedical applications especially in dental related applications.
The search for new parameters for the prediction of type 2 diabetes mellitus (T2DM) or its harmful consequences remains an important field of study. Depending on the low-grade inflammatory nature of diabetes, we investigated three proteins in T2DM patients: 1-aminocyclopropane-1-carboxylate synthase (ACCS), granulocyte–colony-stimulating factor (G-CSF), and Sma Mothers Against Decapentaplegic homolog-4 (SMAD4). In brief, sixty T2DM and thirty healthy controls had their serum levels of ACCS, G-CSF, SMAD4, and insulin tested using the ELISA method. The insulin resistance (IR) parameter (HOMA2IR), beta-cell function percentage (HOMA2%B), and insulin sensitivity (HOMA2%S) were all determined by the Homeostasis Model Assessment-2 (HOMA2) calculator. The predictability of these protein levels was investigated by neural network (NN) analysis and was associated with measures of IR. Based on the results, ACCS, G-CSF, and SMAD4 increased significantly in the T2DM group compared with the controls. Their levels depend on IR status and inflammation. The multivariate GLM indicated the independence of the levels of these proteins on the covariates or drugs taken. The receiver operating characteristic area under the curve (AUC) for the prediction of T2DM using NN analysis is 0.902, with a sensitivity of 71.4% and a specificity of 93.8%. The network predicts T2DM well with predicted pseudoprobabilities over 0.5. The model’s predictive capability (normalized importance) revealed that ACCS is the best model (100%) for the prediction of T2DM, followed by G-CSF (75.5%) and SMAD4 (69.6%). It can be concluded that ACCS, G-CSF, and SMAD4 are important proteins in T2DM prediction, and their increase is associated with the presence of inflammation.
Klebsiella pneumoniae is the most important species of the Klebsiella genus and often causes hospital infections. These bacteria have a high resistance to most of the available drugs, which has caused concern all over the world. In this study, we investigated the antibiotic resistance profile and the ability to produce extended-spectrum beta-lactamase (ESBL) among K. pneumoniae isolates, and then we investigated the relationship between these two factors with biofilm formation and the prevalence of different virulence genes. In this study, 130 isolates of K. pneumoniae isolated from wounds were investigated. The antibiotic resistance of the isolates was evaluated by the disk diffusion method. The microtiter plate method was used to measure biofilm formation. The prevalence of virulence genes was detected by multiplex PCR. Among the examined isolates, 85.3% showed multidrug resistance. 87.6% of the isolates were ESBL-positive. Imipenem, meropenem, and fosfomycin were the most effective drugs. The ability of the isolates to produce biofilm was strong (80%), moderate (12.3%), and weak (7.6%), respectively. fimH, mrKD, entB, and tolC virulence genes were observed in all isolates. High prevalence of antibiotic resistance (especially multidrug resistance), high prevalence of ESBL-producing isolates, the ability of all isolates to biofilm formation, and the presence of fimH, mrKD, entB, and tolC virulence genes in all isolates show the importance of these factors in the pathogenesis of K. pneumoniae isolates in Iraq.
In this study, CH4 production capacity of nitrification bacteria (NB) obtained from the submerged biofilter in the laboratory was investigated. Biochemical methane potential (BMP) test was carried out with the NB amount of zero (control, CR), 5% (R1), 10% (R2), and 15% (R3) at a temperature of about 37 ± 0.5°C. Compared to the CR, significantly higher cumulative CH4 volume of about 290, 490, and 715 mL were determined in the R1, R2, and R3, respectively. All the applied kinetic models gave good results (R2 ≥0.97), while the Transference Function and First-order models provided the better R2 values. The delay phase (λ) was not observed in the AD process, and CH4 production started immediately on the first day of operation. The predicted k value of 0.133 day−1 was high in CR, while it was approximately between 0.078 and 0.112 day−1 for the higher amount of NB containing BMP units, which indicated that the AD required long reaction time. © 2024 Informa UK Limited, trading as Taylor & Francis Group.
The goal of an intrusion detection system (IDS) is to secure data on the network by monitoring the flow of traffic and identifying malicious users. Since there is enormous data available on the network, an optimal selection of features is necessary to get rid of irrelevant and redundant data. Therefore, the given paper introduces a novel technique by making use of a modified firefly optimization algorithm (MFOA), followed by the use of an autoencoder (AE), to improve accounting information security in IDS’s. MFOA acts as an optimal feature selection method that works on the concept of random firefly generation, thereby finding the best feature subset. Now, the reduced set of features is fed as an input to AE for the detection of intrusions and anomalies in the network. The AE comprises an encoder–decoder for generating the reconstructed input dataset. The NSS-KDL dataset is taken into consideration, and the performance of the proposed approach is validated based on evaluation metrics such as detection rate (DR) and accuracy (ACC). The results show that the proposed approach attains higher DR and ACC than the existing machine learning (ML) and deep learning (DL) methods used in the given study.
Concrete pipes both reinforced and unreinforced still serve as efficient subsurface infrastructure, especially when used as culverts and sewer lines. In which its structural performance greatly affected by pipe-soil interaction through installation types. In this study the effect of concrete bedding on the behavior of buried unreinforced concrete pipe is investigated through full-scale experimental testing program which the concrete pipes are embedded in gravelly sand soil that is loose and dense.With thickness of 30 cm over pipe crown and subjected to different surface loadings. Seven standard 300 mm internal diameter precast unreinforced concrete pipes were evaluated in a lab soil box test facility. Two loading conditions are used, namely earth fill that simulated by a uniform loading platform, and wheel load that simulated using a patch loading platform with dimensions of 254 × 508 mm2 (10 × 20 in:2), which is used by AASHTO to mimic the wheel load of an HS20 truck. The results demonstrated that controlled installation utilizing dense compaction granular backfill could achieve 70% of the pipe strength acquired by employing the typical concrete bedding of the indirect design approach. For concrete bedding under patch loads, the greatest bedding factor (ratio between the supporting strength of buried concrete pipe to the three-edge bearing test strength) obtained is 4.53. The failure loads of pipes with concrete bedding is greater than pipes with compacted soil bedding by 30% for uniform loading and 43% for patch loading.
Hundreds of studies have been written in the last several decades on the advantages of using stone powder as a raw material in the production of fired clay bricks. The durability and long-term behavior of the finished product, however, have received very little attention in the literature. Clay bricks are generally fired at high temperatures in developing countries, which reduces the mechanical performance of the bricks. This is especially evident in extreme environmental settings where weathering leads to significant damage. The evaluation of concrete waste (stone powder) used to make fired clay bricks is the main topic of this study. There are two sections: the first evaluates how adding stone powder to clay bricks improves their physical characteristics such absorption, efflorescence, density, and firing shrinkage. The impact of stone powder on the mechanical characteristics of specimens of burned clay bricks, such as compressive and flexural strengths, is covered in the second section. The percentages of stone powder in the clay bricks are 0 %, 5 %, 10 %, 15 %, and 20%. While the ratio of dry soil to water content remains is 0.3. In this work three fire phases are used untel to the maximum temperature is reached. The first one is 300 °C, the second phase is 600 °C, and 900 °C for the third phase. The water absorption of specimens decreased as the quantity of stone powder increased, and efflorescence also decreased, according to the results for the physical attributes. The density does, however, somewhat rise with the amount of stone powder. Additionally, when the amount of stone powder was increased, the experimental results indicated that firing shrinkage decreased. Mechanically considered, clay brick specimens with 20% more stone powder showed stronger compressive flexural capabilities.
Introduction: This study aimed to identify bacterial species isolated from urine and stones, to determine their sensitivity to antibiotics, and also to perform a chemical analysis of stones, focusing on the most prevalent type. Patients and Methods: One hundred adult patients with renal stones admitted to the surgical department of Al-Zahrawi surgical hospital in Maysan governorate were enrolled, then urine and surgical stone cultures were gathered. Bacterial identification was conducted using 16S rDNA gene sequencing. Additionally, a qualitative chemical composition analysis of stones was conducted. Results: A total of 130 bacterial isolates were identified (comprising nine different species), Escherichia coli was the predominant bacterium in both urine and stone cultures (41 and 20 isolates respectively), followed by Klebsiella pneumoniae (15 and 9, respectively) and Proteus mirabilis (11 and 8 respectively). Most isolates showed high sensitivity to imipenem and amikacin (80% and 71.5%, respectively; P<0.01), while sensitivity to tetracycline, sulfamethoxazole/trimethoprim, nitrofurantoin, and ampicillin was notably lower (30.7%, 24.9%, 21.5% and 12.3% respectively). The incidence of renal stones was more frequent in males (64%), particularly among patients aged 31-40 years (60%), with a significant difference at P ≤ 0.05. Additionally, calcium oxalate was the most common biochemical composition of stones (51%), followed by calcium phosphate and uric acid (19% and 15% respectively), since magnesium-ammonium phosphate, calcium carbonate, and cystine were less common (9%, 4%, and 2%, respectively). There was also a significant relationship between bacterial urinary tract infection and the presence of renal stones. Conclusion: The most common bacteria isolated from adult patients with renal stones in Maysan governorate were Escherichia coli, followed by Klebsiella pneumoniae and Proteus mirabilis. Calcium oxalate stones were most frequent, followed by uric acid. The infection rate between urinary tract infection and renal stones was 65% and this is considered significant.
