Diabetic nephropathy is a kidney disease that develops as a complication of diabetes, and it is issociated with renal impairment with increasing age. Renal impairment among diabetic individuals can be detected using serum markers of glomerular filtration rate and microalbuminuria. This study was carried out at AL-Hussein Hospital and Consulting Laboratories .The study period extended from October 2024 to January 2025. aiming to assess the biochemical changes in kidney failure patients with and without diabetes. Based on the results, it was noted that diabetic patients had higher levels of total protein and lower levels of albumin compared to the healthy control group. Additionally, patients with diabetic nephropathy had elevated levels of liver enzymes (ALT, AST, and ALP), C-reactive protein (CRP) ,and calcium. A noticeable lower iron levels were observed in both diabetic and diabetic nephropathy groups compared to the healthy control group.

Three samples of pure CdSe doped with zinc (4% and 8%) were prepared by the slow cooling method at 325°C and pressed into discs. The structural properties of the prepared samples were studied using XRD. It was found that the structure was cubic and polycrystalline, as the crystallization phase did not change as a result of doping with zinc. Using a Senko fluorescence spectrometer, the fluorescence spectrum of the prepared samples was studied, and it was observed that the intensity of fluorescence increases with zinc doping ratio due to the appearance of two peaks at 631.8nm and 704.9nm. By studying the electrical properties (I-V) of the prepared samples, it was observed that there is an improvement in the electrical conductivity of the compound (CdSe) after doping it with zinc, and from calculating the activation energy (Ea) of the samples, it was found that it decreases with increasing zinc doping ratio in order to form impurity levels above the energy gap.

Dapagliflozin has emerged as a promising therapeutic agent for reducing cardiovascular risk in patients with type 2 diabetes mellitus and concomitant heart failure (HF).The present study aims to investigate the impacts of dapagliflozin on some oxidative stress markers, including nitric oxide (NO) , fasting blood glucose (FBG), superoxide dismutase (SOD), and catalase (CAT), in patients with HF in comparison with healthy controls.
The study included 150 participants : 100 patients who had type 2 diabetes mellitus (T2DM) and HF, and 50 normal subjects (controls). Based on age, the patients were divided into two groups (40-70 years). Group A received both Lasix and Dapagliflozin , whereas Group B received Lasix only. According to the data, serum FBG and GAL-3 concentrations in groups A and B were significantily higher than those in the control (p≤ 0.05 ). In comparison to the controls, groups A and B showed a significant decrease in serum CAT, SOD, and NO concentrations( p≤ 0.05). There was no been any significant difference in serum concentration of Gal3, FBG, CAT, SOD, and NO between groups A and B upon admission, according to the results. Significant differences were observed in the concentrations of serum Gal3, FBG, CAT, SOD, and NO between groups A and B at 7 days. Additionally, patients in groups A and B had significantly lower serum Gal3 and FBG concentrations than on the day of baseline, and patients in groups Aand B had significantly higher serum CAT, SOD, and NO concentrations than on the day of baseline. Dapagliflozin administration in patients with heart failure and type 2 diabetes for seven days led to decreased FBG and GAL-3 levels, and increased SOD, CAT, and NO levels. These findings suggest its role in reducing oxidative stress and improving cardiac and vascular function in a short time

Modest and delicate kinetic approaches are industrialized used for the resolve of Para-amino benzoic acid in unadulterated form and in pharmaceutical measures. The process is based on diazotization of benzoic acid and coupling with 1,2,3-Trihydroxybenzene in natural medium to form a brown-reddish water-soluble azo dye, that has a maximum absorption at 446nm.

In the field of materials science, "green" synthesis has received significant attention as a reliable, sustainable, and environmentally friendly method for producing diverse materials and nanomaterials, such as hybrid materials, bioinspired materials, and metal/metal oxide nanomaterials. Green synthesis is a crucial tool for mitigating the harmful effects of conventional nanoparticle synthesis techniques widely used in laboratories and industry. In this study, we provide an overview of the basic procedures and mechanisms of action of "green" synthesis methods, specifically for metal nanoparticles and metal oxides such as copper oxide (CuO), made using natural extracts. Key phytochemicals, such as flavonoids, alkaloids, and terpenoids, serve as solvent systems and reducing agents. The synthesized nanoparticles were examined using several techniques, such as scanning electron microscopy (SEM), X-ray diffraction (XRD), and ultraviolet–visible spectroscopy. UV–vis: The best results were obtained at 70 °C and pH 9 and pH10,45 ℃. Spectroscopic analysis of the synthesized copper solution showed an absorption peak at 242 nm. XRD spectra of the biosynthesized copper oxide nanoparticles yielded a series of diffraction peaks at 2θ angles, which correspond to the h, k, and l values of the reflections. SEM revealed that the resulting copper oxide particles had a spherical shape, with an average particle size ranging from 32 to 65 nm. This study aimed to produce nanoparticles using green methods using the aqueous extract of Typha domingensis at low cost and low toxicity

Cataracts are a progressive health issue with significant implications for individuals and public health systems. They are considered a critical global health issue, particularly affecting older adults. MMP-2 and CCL4 are both chemokines that are known to play a critical role in inflammation and tissue remodeling. The collected data were analysed by using SPSS and visualization tools. Our results indicate a significant correlation between MMP-2 and CCL4 among cataract patients. There is a substantial relationship between MMP-2 and other factors, such as gender and residency state, unlike CCL4. No significant correlation exists between the two serum biomarkers (MMP-2 and CCL4) and smoking cataract patients. By exploring the expression of MMP-2 and CCL4, this study aims to enhance cataract pathophysiology and identify inflammatory biomarkers associated with cataract progression. measuring serum levels of MMP-2 and CCL4 in cataract patients to assess their role in tissue remodeling, inflammation, and post-operative complications

In order to learn many new concepts and details in our field of study, we analyzed and investigated a number of prior studies in this work. The majority of these studies were conducted within the last five years, and they covered techniques for removing heavy metals from aqueous media by measuring various physical and chemical properties like initial concentration pH, and how these properties affect heavy metals in this study, we used heavy metals like Copper, Zinc, and Lead. Zn = 80.7% in sewage water, Cu = 97.10% in drinking water, and lead (Pb) = 100% in industrial medium. Natural zeolite was the most effective adsorbent material utilized in the removal procedure, along with silica and live bacteria. Adsorbents are used to remove heavy metals from aquatic media. The effectiveness of these materials in removing these heavy metals from polluted water has been confirmed. This removal is done according to certain conditions, such as pH, temperature, etc., and the removal efficiency varies from one metal to another. This is what we will confirm in this chapter by discussing various references and modern scientific articles in which heavy metals were investigated from polluted water using different adsorbent materials

This study aimed to investigate the relationship between serum vitamin B12 concentrations and lipid profiles in type 2 diabetic patients with dyslipidemia. We conducted this study in Thi Qar Province, Iraq, during the late summer and early fall of 2023. The investigation included 50 patients with confirmed type 2 diabetes and a comparison group of 50 healthy volunteers who helped establish baseline values. The findings were quite revealing that patients dealing with dyslipidemia showed much higher triglyceride, total cholesterol, LDL, and VLDL levels than our control group (P≤0.05). Conversely, HDL cholesterol levels were significantly reduced in this group (P≤0.05). we also noticed that Type 2 diabetics with dyslipidemia had considerably worse lipid profiles compared to those with normal lipid measurements. We found a relationship between vitamin B12 levels and abnormal lipid patterns in the dyslipidemia group. These findings suggest that monitoring vitamin B12 status should be considered as part of comprehensive lipid management strategies in type 2 diabetic patients. Our findings open doors to potential new treatment approaches, as B12 deficiency might be playing a significant role in lipid disorders among Type 2 diabetics - something that's often overlooked in current treatment protocols

Enterobacter cloacae is an opportunistic pathogen frequently associated with a wide range of clinical infections. Given the increasing prevalence of this bacterium and the limited information available on its virulence factors in Iraq, further investigation is warranted. This study aimed to analyze various clinical samples, accurately identify the presence of E. cloacae using diverse analytical methods, and confirm the findings through advanced diagnostic systems.

The results of this study demonstrated that combining serological and molecular diagnostic methods improves the accuracy of H. pylori detection in patients

Staphylococcus aureus (S. aureus) is a pathogenic strain of bacteria, that resists multiple multi-antibiotics used for common bacterial infections. Most S. aureus infections occur among people consulting hospitals or other healthcare settings such as nursing homes and dialysis centers. This study aimed to molecularly identify S. aureus strains associated with nosocomial infections in hospitals of Thi-Qar. A total of 100 samples were collected from various locations in three hospitals in Thi-Qar Governorate. Polymerase Chain Reaction (PCR) technique was utilized to assay the presence of S. aureus via 16S rRNA gene. The study population consisted of both male and female patients, with a male predominance (82% males vs. 18% females), showing statistically significant differences (p ≤ 0.01). The highest frequency of isolates (65%) was observed in the 21–31 age group, which also demonstrated a significant difference compared to other age groups. The PCR amplification of the 16S rRNA gene was successfully submitted to GenBank and assigned the accession numbers LC866513, LC866514, and LC866515. Phylogenetic analysis using MEGA-10 software revealed distinct molecular relationships between the local S. aureus isolates and genetically related strains from various regions worldwide.
The outcomes of this study provide valuable insights that could inform and enhance infection control practices, thereby contributing to the mitigation of disease transmission within healthcare environments

The electrodes were used for the determination of the drug in tablets by potentiometric analysis

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder associated with systemic complications, including hematological and immunological alterations. This study aimed to assess differences in hematological and serological parameters between patients with T2DM and matched non-diabetic controls.
A case-control study with matching was conducted between November 17, 2024, and February 2, 2025, at Smart Health Tower–Raparin, Ranya City. There were 176 participants, with 88 patients with type 2 diabetes mellitus and 88 matched healthy controls. Comparative hematological and biochemical marker measurements between the groups were made using the Mann–Whitney U test. Spearman’s rank correlation was used to estimate the correlation of intercellular adhesion molecule-1 and interleukin-31 with different laboratory markers. The chi-square and Fisher tests were used to compare the frequency distribution of abnormalities in the blood film. A p-value < 0.05 was considered significant.
T2DM patients had significantly higher levels of HbA1c, fasting blood glucose, CRP, ESR, ICAM-1, IL-31, ferritin, total cholesterol, LDL, triglycerides, VLDL, and lower HDL (all p < 0.01). Morphological abnormalities were significantly more frequent among diabetics. IL-31 showed strong positive correlations with HbA1c (r = 0.68), glucose (r = 0.56), CRP (r = 0.45), and ESR (r = 0.30) (all p < 0.01). ICAM-1 was not significantly correlated with other measured parameters.
T2DM is associated with significant hematological and biochemical alterations, including elevated inflammatory markers and abnormal red cell morphology. Regular monitoring of these parameters may aid in the early detection and management of diabetes-related complications

Rheumatoid arthritis (RA) is a systemic autoimmune disorder primarily characterized by persistent inflammation of the synovial joints, often with extraarticular involvement affecting multiple organ systems. Despite extensive research on inflammatory and hematological parameters in Iraqi RA patients, a significant gap exists in region-specific data, particularly for Anbar Governorate. This study aimed to assess and compare levels of key inflammatory and immunological markers—erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide (Anti-CCP) antibodies, white blood cell (WBC) count, and interleukins IL-17 and IL-21—between RA patients and healthy controls in Anbar, Iraq.A case-control study included 50 RA patients and 40 healthy controls. Markers (ESR, CRP, RF, Anti-CCP, WBC) were measured via routine lab techniques, while IL-17 and IL-21 used ELISA. Significance was set at p < 0.05.RA patients’ mean age was 49.58 ± 11.36 years; controls was 33.80 ± 12.20 years. RA group: 80% females (40), 20% males (10); controls: 60% females (24), 40% males (16). Results showed significantly elevated ESR and CRP in patients (P < 0.001). RF and Anti-CCP were positive only in patients (P < 0.001), underscoring diagnostic value. WBC, IL-17, and IL-21 exhibited no significant differences, though mildly higher in patients.Conclusion: ESR, CRP, RF, and Anti-CCP are effective for differentiating RA. WBC, IL-17, and IL-21 have limited standalone utility. Further research on cytokine profiles in RA subtypes and progression is recommended

Biofilm formation by the accumulation of various pathogens may be responsible for chronic and acute human infections. This research aimed to explain the role of Candida albicans in biofilm formation with pathogenic bacteria isolated from clinical samples. Ninety clinical samples were collected to isolate pathogenic bacteria and Candida albicans. The isolation and identification of these pathogens were performed using selective media and the VITEK 2 system. Flat-bottom microtiter plates were used to evaluate the ability of all isolates to form biofilms in case of monomicrobial and polymicrobial species. Three pathogenic bacteria, including Staphylococcus aureus (n=8), Pseudomonas aeruginosa (n=8), and Escherichia coli (n=4), as well as C. albicans (n=20), were isolated. All isolates were submitted to evaluate their ability to form monomicrobial and polymicrobial biofilms. In the case of monomicrobial species, C. albicans (100%) and bacterial species (80%) showed a high percentage of biofilm formation. However, C. albicans was prepared to make an adherence phase for each one of S. aureus, P. aeruginosa, and E. coli. In this experiment, all bacterial isolates improved their ability to form polymicrobial biofilms. in contrast, some bacterial isolates reduce their ability for forming polymicrobial biofilms if bacterial isolates are used as an adherence phase. In conclusion, the replacement of adherence phase of the polymicrobial biofilm causes either an increase or a decrease in the ability of organism to form a biofilm when compared to monomicrobial biofilms

In this study, density functional theory (DFT) calculations have been conducted using the B3LYP hybrid functional with the 6-31G basis set. The computational procedures have been implemented via the Gaussian 09 software package to find out the molecular geometries, electrostatic potential surfaces, contour density maps, infrared spectroscopy (IR) diagnostics, density of states (DOS) schematics, and symmetry of the nanoclusters (4GaAs/2Ti₂O₃), (6GaAs/2Ti₂O₃), (4GaAs/2Ti₂O₃)-4Zn, (4GaAs/2Ti₂O₃)-4F, (6GaAs/2Ti₂O₃)-4Zn and (6GaAs/2Ti₂O₃)-4F. The electronic characteristics: HOMO energy, LUMO energy, band gap (E_g), dipole moment, polarizability, electronegativity, and electrophilicity have been evaluated for the nanoclusters under study. The contour density maps revealed the active regions in the molecular system after the overlap between the hybrid nanoclusters (GaAs/Ti₂O₃) and the impurities, (fluorine, zinc). One can visualize that the (4GaAs/2Ti₂O₃)-4Zn nanocluster exhibited a band gap of approximately to (0.699 eV), which is comparable to that of gallium antimonide (GaSb), which has an energy gap of approximately (0.7 eV), indicating its potential suitability for thermophotovoltaic (TPV) systems, laser diodes, and transistor devices. Furthermore, the symmetry demonstrated that the hybrid nanocluster (4GaAs/2Ti2O3) has the point group symmetry (Cs/C1), but after the interaction with the impurities, fluorine and zinc, the symmetry becomes (C1). Symmetry merit plays a vital role in optics in physics, especially the optical activity and influence on electronic transition probabilities. The doping by the impurities zinc and fluorine atoms leads to the emergence of new energy states and this is very apparent in the diagrams of the density of states

Copper oxide (I)/carbon-based nanomaterials have a great attention nowadays due to their potential in electronic and thermoelectric applications. In this study, density functional theory (DFT) was applied using the B3LYP hybrid function and the B3LYP 6-31G basis set to study the properties of (6Cu2O/C17) and (4Cu2O/C8) structures, as well as their interactions with zinc sulphide (ZnS) and zinc (Zn). The calculations included the determination of molecular geometry, contour density maps, electrostatic potential surfaces, spectra, HOMO and LUMO energies, band gap, dipole moment, polarizability, point group symmetry, and three states (DOS). The results showed that the interaction between (6Cu2O/C17) and (Zn, ZnS) led to a clear charge transfer and exchange, which was reflected in the density and electrostatic potential maps. The structures (6Cu2O/C17), (6Cu2O/C17–Zn), and (6Cu2O/C17–ZnS) also revealed narrow band gaps (~0.3 eV), which enhances their thermoelectric properties. Furthermore, interaction with ZnS increased the dipole moment from (2.99 Debye) to (15.33 Debye), indicating its potential for use in high dielectric materials. The (4Cu2O/C8) structure showed Cs group symmetry, which makes it important for optical applications. DOS maps also showed the emergence of new energy states resulting from interaction with Zn and ZnS. These results demonstrate that the studied nanostructures possess promising electronic, optical, and thermoelectric properties, qualifying them for practical applications in energy conversion and advanced device fabrication

The samples that were positive for bacterial growth were 150 samples, including 30 XDR samples, 20 sensitive to antibiotics, and 100 MDR samples, pathogens isolated MDR included Escherichia coli (44%), Staphylococcus aureus (33%), Klebsiella pneumoniae (10%), and Proteus mirabilis (13%). Regarding resistance genes: BlaCTX-M was detected in 81.8% of E. coli, 100% of K. pneumoniae, and 30.8% of P. mirabilis; BlaSHV in 29.5% of E. coli, and 100% of both K. pneumoniae and P. mirabilis; BlaAMPC in 90.9% of E. coli, 100% of K. pneumonia, and 30.8% of P. mirabilis; and BlaTEM in all Gram-negative isolates. Additionally, the mecA, ermA, and ermC genes were found in 100% of S. aureus isolates. Analysis of TLR4 SNPs revealed that the homozygous CC and heterozygous GC genotypes of TLR4-rs7873784 was significant risk factor indicating increased susceptibility to MDR UTIs in individuals carrying these genotypes

This current study investigated the association between functional gene polymorphisms Toll-like receptors 4 (TLR4 rs11536889) and susceptibility to multidrug-resistant (MDR) bacterial urinary tract infections (UTIs). A total of 350 urine samples were collected from male and female patients aged 10 to 75 years at Al-Rifae General Hospital in Thi-Qar province, southern Iraq, between July 2022 and January 2023 .All bacterial isolates were identified biochemically and by the VITEK-2 system. All isolates were then confirmed with the 16S rRNA gene and resistance genes were detected using bacterial colonies in a PCR test. Tetra-ARMS-PCR was used to detect TLR4 gene polymorphism (rs11536889). Of these, 150 samples (42.9%) showed positive bacterial growth, while 200 samples (57.1%) were culture-negative. The samples that were positive for bacterial growth were 150 samples, including 30 XDR samples, 20 sensitive to antibiotics, and 100 MDR samples Pathogens isolated from MDR samples included Escherichia coli (44%), Staphylococcus aureus (33%), Klebsiella pneumoniae (10%), and Proteus mirabilis (13%). Genotypic analysis of the TLR4 rs11536889 single nucleotide polymorphism SNP (TLR4 rs11536889) indicated that individuals carrying the homozygous CC and heterozygous GC genotypes exhibited a significantly increased risk of developing MDR UTIs, suggesting a potential role for this SNP (TLR4 rs11536889) in host susceptibility to infection, therefore, this polymorphism may serve as a valuable genetic biomarker for the early diagnosis of UTI susceptibility and could contribute to personalized therapeutic approaches, helping to identify individuals at greater risk for resistant infections and to guide appropriate preventive or treatment strategies

Polycystic ovarian syndrome is a common endocrinopathy in reproductive-aged women, associated with metabolic dysfunction influencing mineral metabolism and calcium regulatory pathway and affecting bone health. Thus, this study conducted to pinpoint specific hormonal abnormalities in PCOS women and to elevate their correlation with calcium homeostasis markers. A hundred specimen recruited from Iraqi women (50 PCOS patient and 50 serving as a control group (aged 18-40 years old). PCOS group was diagnosed according to standard Rotterdam criteria and were compared with controls without PCOS compatible in age and BMI. Blood samples were collected to quantify E2, LH, FSH, P.TH, Ca2+, and total testosterone by using hormone’s analyzer Addendum-Mini VIDAS apparatus (VIDAS) 12 mode l0, 1992. The PCOS group demonstrated higher LH, testosterone and calcium levels (4.96 ± 1.00) (0.64 ± 0.17) (10.37 ± 0.86) respectively, with decreased E2 and P.TH (55.12 ± 14.67) (25.08 ± 4.54) respectively when compared with control group, while FSH remained statistically unchanged. The data revealed a robust positive calcium-E2 correlation and an inverse E2-testesterone correlation implying a potential link between calcium homeostasis and ovarian steroidogenesis

The growing demand for sustainable nanomaterials has intensified interest in green synthesis routes utilizing plant-derived biomolecules as reducing and stabilizing agents. This study reports, for the first time, the biosynthesis of nickel oxide nanoparticles (NiO NPs) using Microtrichia perotitii DC leaf extract, a medicinal plant rich in bioactive phytochemicals including flavonoids, alkaloids, tannins, phenolics, and saponins. Nickel (II) chloride hexahydrate served as the metal precursor, while the phytochemicals facilitated both nanoparticle formation and stabilization. The synthesized NiO NPs were comprehensively characterized using UV-visible spectroscopy, Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDX), and thermogravimetry/differential thermal analysis (TG/DTA). XRD analysis confirmed the formation of crystalline nanoparticles with an average crystallite size of 24 nm and a cubic bunsenite phase. FTIR spectroscopy revealed a characteristic Ni-O stretching vibration at 651 cm⁻¹, confirming successful NiO formation. SEM imaging showed irregular, agglomerated nanostructures, while TG/DTA analysis demonstrated good thermal stability with major decomposition occurring at 473°C, attributed to the removal of phytochemical residues. Antibacterial assays demonstrated strong inhibitory effects of the biosynthesized NiO NPs, particularly against Gram-positive bacteria, including Bacillus subtilis (18.8 ± 0.6 mm) and Staphylococcus aureus (19.6 ± 0.4 mm) at 100 µg/mL concentration. Although the activity was slightly lower than ciprofloxacin (5 µg/disc: 22.4 ± 0.5 mm and 23.1 ± 0.43 mm, respectively), it indicates significant antibacterial potential. Gram-negative strains exhibited comparatively lower sensitivity, likely due to their protective outer membrane barrier. This first report of M. perotitii-mediated NiO NP synthesis highlights the untapped potential of this indigenous West African plant for eco-friendly nanomaterial production and demonstrates the applicability of these nanoparticles in biomedical and environmental applications

This study focuses on CO₂ edge adsorption mechanism, in which the CO₂ molecules interact at the edge sites of the graphene quantum dots (GQDs), leading to significant electronic and chemical modifications analyzed using the density functional theory (DFT). Edge adsorption plays a dominant role in governing the electronic characteristics and chemical reactivity of GQDs. The energetic and chemical properties were studied for the pristine GQDs and those functionalized with one to four CO₂ molecules at their edges. The results reveal that the CO₂ edge adsorption causes a substantial reduction in the energy gap up to 91.2% for GQDs modified with four CO₂ molecules. This adsorption also influences the Fermi level, HOMO–LUMO energies, and global chemical descriptors, including the ionization potential, electron affinity, chemical hardness, and electrophilicity. Furthermore, a saturation state is observed upon adsorption of four CO₂ molecules, beyond which additional adsorption produces negligible changes in electronic properties. These findings demonstrate that the CO₂ edge adsorption provides an effective and environmentally friendly strategy for tailoring the electronic and chemical behavior of GQDs, making them promising candidates for nanoelectronic, sensing, and energy-related applications

TORCH is a group of pathogens that can infect a pregnant woman and subsequently transmit the infection to the fetus. These include the parasite Toxoplasma gondii, and other pathogens such as Treponema pallidum, parvovirus B19, rubella, Human cytomegalovirus, and herpes simplex virus. TORCH infections are among the most significant risks to fetal development, leading to congenital malformations and other complications transmitted from the mother and causes congenital malformations. Therefore, this review aims to provide a comprehensive overview of TORCH infection, including diagnostic methods, such as serological tests, PCR, and ultrasound imaging, to detect fetal malformations such as cerebral calcifications, hydrocephalus, and organ enlargement. The review also explained the treatment used for this infection, If a mixture of pyrimethamine and sulfadiazine is used with folic acid to treat, while the vaccine is used before pregnancy for the purpose of preventing German infection, as for CMV infection, acyclovir or ganciclovir is usually used, while penicillin is the treatment for Treponema pallidum. This review focuses on the clinical manifestations on the clinical manifestations of TORCH infection as a cause of congenital malformations in fetuses, presents the most important methods that can be used for accurate diagnosis, compares the protocols used for treating each infection in this group, and evaluates methods of prevention
