An Investigation of the Correlation Between the CNTNAP2 rs7794745 gene Polymorphism and Autism in Children from the Middle Euphrates Area of Iraq

2024-09-11T17:00:33+00:00

Background: Autism is an incurable condition that may be attributed to several factors, such as genetic predisposition and environmental influences. Multiple studies have discovered that a substantial number of genes linked to autism serve as constituents of signaling pathways that regulate the plasticity of synapses and development, hence exerting a notable impact on the origins of the illness. CNTNAP2 is increased during the initial phases of neural tube development. Given the increasing worldwide occurrence of autism, there is a growing demand for effective teaching methods and educational programs.

Methods: A case-control study recorded 90 samples, comprising 50 autistic individuals (males and females, mean age 4.5 ± 2 years) and 40 healthy youngsters (5 ± 2 years). PCR and restriction enzymes are used in polymerase chain reaction-restriction to amplify and analyze DNA sequences. PCR-RFLP genotyped CNTNAP2 at rs7794745. Genomic DNA was isolated from peripheral blood cells of healthy children while buccal cells were swapped from patients to obtain and genotype their DNA.

Results: Our results revealed that the low-frequency distribution (p-value > 0.05) of the rs7794745 SNP is statistically non-significant in ASD patients compared to healthy children.

Conclusion: Our case-control study suggests that rs7794745 polymorphism is unrelated to ASD.

The Effects of Extreme Electrospinning and Environmental Parameters on the Resulted Zein Nanofibers Formulated by the Electrospinning Technique

2024-09-11T19:13:19+00:00

Objective: The study declares and shows the effect of electrospinning parameters, including the temperature, humidity, applied voltage, syringe gage, the distance between the needle tip and collector, and flow rate on the morphology of the resulted nanofiber using the electrospinning technique in the preparation of Zein polymer nanofibers.

Methods: The Zein nanofiber was formulated as nanofibers using an electrospinning apparatus. The nanofibers were prepared in different conditions, adjusting the parameters in each single run-in various temperatures and humidity. At the same time, the concentration of the zein polymer remained constant in all of the runs. Then, the nanofibers obtained after drying and collecting them from the aluminum foil were transferred to a tightly sealed container. The nanofiber was characterized using Attenuated Total Reflectance Infrared Spectroscopy (FTIR) to detect the presence of Zein polymer in the matrix. Then, the surface morphology of nanofibers was analyzed using the Scanning Electron Microscopy (SEM) technique. To declare the morphologic changes in the resulting nanofibers.

Results: The results indicate that some specific parameters and conditions can lead to perfectly shaped nanofibers, and applying different conditions and parameters can lead to abnormal morphological topography and electro-spraying instead of electrospun nanofibers.

Conclusions: The SEM images provided visual evidence of the change in morphology that resulted in each different run-in with different conditions and parameters.

Aim of the Study: This study aimed to identify the effect of different electrospinning and environmental parameters on the resulting zein polymer nanofibers.

Serological Evaluation of Systemic Lupus Erythematosus: Association with Disease Severity in Iraqi Patients

2024-09-11T20:34:46+00:00

The diagnosis, management and treatment of systemic lupus erythematosus (SLE) in clinical settings often involve serological measures of autoantibodies, specifically the anti-double stranded DNA and generally the anti-nuclear autoantibodies (ANA). It remains to be shown, however, whether these serological measures correspond with the severity classification of SLE, particularly among Iraqi patients. Here, we investigated the relationship between serological measurements of autoantibodies and complement proteins with severity classification of SLE patients. Sixty patients clinically diagnosed with SLE, along with 60 age-matched non-SLE individuals (control) were recruited in the study. Serum levels of ANA, anti-dsDNA, complement C3 and C4 were measured. The SLE patients had significantly higher mean values of ANA, anti-dsDNA, with significantly lower levels of C3 and C4 compared to those of the control (non-SLE). With respect to their SLE disease severity classification, while levels of ANA significantly increased with severity of disease (mild, 7.99±0.65 IU/mL; 9.83±0.93 IU/mL; severe, 13.70±1.60 IU/mL; p = 0.004), levels of anti-dsDNA despite increasing (mild, 33.38±2.18 IU/mL; moderate, 39.32±2.28 IU/mL; severe, 42.84±4.80 IU/mL), were not statistically significant (p = 0.101). (p < 0.05). Conversely, levels of C3 (mild, 1.19±0.05 g/L; moderate, 0.98±0.11 g/L; severe, 0.72±0.17 g/L; p = 0.009) and C4 (mild, 0.32±0.02 g/L, moderate, 0.29±0.03 g/L; severe, 0.16±0.03 g/L; p = 0.002) significantly decreased with disease severity (p < 0.05). Our findings show that although ANA and anti-dsDNA autoantibodies may be important in the diagnosis of SLE, their use in predicting the severity of the disease varies considerably, while also highlighting, the significance of complement components C3 and C4 in monitoring and predicting the severity of the disease in addition to their role in the diagnosis of SLE.

Studying the Role of L-Thyroxine in Long-Term Management of Hypothyroidism: A Comparative Analysis with Healthy Control

2024-09-11T20:44:49+00:00

Background: Hypothyroidism, characterized by insufficient thyroid hormone production by the thyroid gland, which may lead to significant challenges to metabolic health and overall well-being. Hence, studying the intricate correlation between thyroid biological functions, metabolic pathways and treatment outcomes are crucial for patients care management. Although, recent researches have clarified the complexity between thyroid hormone levels and metabolic pathways, there are still unanswered questions about the specific mechanisms and practical implications.

Patients and methods: Across sectional study was conducted in Iraq from September 2023 to July 2022 involved 100 females with hypothyroidism undergoing L-thyroxine therapy for at least four months and 50 healthy subjects as control. Blood samples was collected after an overnight fast for plasma extraction. Various biochemical and hormonal assays were performed including TSH, TT4, FT4, TT3, FT3, TSH, fasting plasma glucose, insulin levels, HOMA-IR, cholesterol, triglycerides, HDL, LDL, VLDL, and BMI calculations for categorizations into weight groups.

Results: there were notable differences in weight, blood pressure, and BMI but not in age between patients with hypothyroidism and healthy controls. In addition, patients with hypothyroidism showed decreased FT4 levels, which suggested problems with the regulation of free thyroxine, along with increased TSH and FT3 levels, which indicated thyroid dysfunction and hyperactivity. Furthermore, patients had lower HOMA-IR indices and impaired glucose metabolism, highlighting the complex relationship between thyroid function and metabolic parameters. Patients had dyslipidemia indicated by elevated total cholesterol and triglyceride levels, and altered lipid metabolism was suggested by lower VLDL levels. Long-term L-thyroxine therapy resulted in a tendency toward lower TSH levels, with TT3 levels fluctuating over the course of treatment.

Conclusion: The aforementioned results offer fresh perspectives on the intricate relationships among thyroid function, metabolic markers, and treatment results in hypothyroidism. They underscore the necessity for additional investigation to clarify underlying mechanisms and enhance clinical management approaches.

Molecular Docking Study of Five Novel 1,2,3-Triazole Linked Metronidazole Derivatives as Cytotoxic Agents

2024-09-11T21:35:46+00:00

Background: Five novel synthetic 1,2,3-triazole-linked metronidazole compounds that target the tyrosine kinase of the epidermal growth factor receptor belong to the ErbB receptor family, which includes Her1 (EGFR), Her2 (erb-B2), Her3 (erb-B3), and Her4 (erb-B4). Certain human carcinomas, such as lung and breast cancer, feature cells that overexpress EGFR. This causes the anti-apoptotic Ras signaling cascade to be incorrectly activated, resulting in uncontrolled cell growth. Inhibiting EGFR TK (PDB code: 1M17) is an important target in the development of anticancer drugs since it can help prevent tumor growth and metastasis.

Materials and Methods: Using the molecular operating environment to evaluate the binding affinity of new design compounds against targeting proteins (EGFRTK). The molecular docking process predicts how molecules interact with the target enzyme, and criteria such as S-score and RMSD evaluate the docking outcomes by comparing estimated and experimental structures. It is an extremely useful tool for drug discovery and studying molecular interactions.

Results: The newly synthesized compounds (I-V) demonstrated improved binding energy (S.score) ranging from -7.5733 to -8.4456 Kcal/mol and reduced rmsd values ranging from 0.8752 to 1.6182 with the enzyme active site, as compared to erlotinib's binding energy of -7.7359 Kcal/mol and rmsd value of 1.720.

Conclusion: The docking results demonstrated that all synthesized compounds (I-V) had higher energy of binding (S-score) and lower Root Mean Square Deviation (RMSD) values, indicating theoretical potential as effective EGFR inhibitors when compared to the reference ligand (erlotinib)

2024-09-11T22:16:13+00:00

Background: There is a great deal of mortality and morbidity associated with various cardiovascular diseases that comprise acute coronary syndrome (ACS). One crucial factor in the development of ACS is inflammation of the coronary plaque. Cell adhesion molecules play a key role in the inflammatory cascade. The vascular endothelium is directly affected by elevated levels of pro-inflammatory cytokines and other systemic inflammatory markers in ACS related to atherogenesis. This causes an increase in the expression of adhesion molecules, such as selectins.

Objective: This study aims to document the inflammatory response after acute coronary syndrome by evaluating the association between serum E-selectin levels and the risk and severity of acute coronary syndrome.

Materials and Methods: A case-control study involving 120 male subjects aged 41–70 years, who were divided into two groups: 60 ACS patients and 60 healthy individuals as a control. Serum E-selectin levels were measured using an ELISA technique.

Results: The study revealed a significant increase in serum E-selectin levels when comparing patients to the healthy control group (216.07±20.26 pg/ml Vs 179.74±53 pg/ml, P ≤ 0.0001) respectively. The analysis of the receiver operating curve (ROC) for E-selectin showed a sensitivity of 85%, a specificity of 70%, a 95% confidence interval (CI) of 0.673-0.863, and the area under the curve (AUC) was 0.768. The cut-off point was set at 197.37 pg/ml or higher.

Conclusion: Elevated serum E-selectin levels in ACS patients suggest a potential role for adhesion molecules in the pathogenesis of ACS. Adhesion molecules could be considered as a biochemical marker for assessing ACS.

Adipokine levels and interleukin have been reported to be significantly increased in serum and synovial fluid (SF) of RA patients.

The study aimed to investigate the association between the levels of Leptin in the circulation of individuals with rheumatoid arthritis (RA).

Methods and Patients: The present work included a case-control study for a group of (90) samples: (60) patient samples and (30) healthy control samples. Patients with Rheumatoid arthritis were selected from Imam Hassan al-Mujtaba Hospital in Kerbala. The sociodemographic aspects of the patients were collected through the self-reported technique (student questionnaire). All patients underwent clinical history, clinical examination, and relevant laboratory investigations. The degree of rheumatoid was identified based on the evaluation of laboratory measurements for the clinical assessment of rheumatoid arthritis. An enzyme-linked immunosorbent assay system (ELISA) was performed using the sandwich-ELISA method to measure the concentrations of serum IL-33. At the same time, a competitive enzyme immunoassay kit was used to detect human Leptin in serum samples quantitatively. Statistical analysis was performed, and the efficiency of the predicting value was assessed using the receiver operating characteristic (ROC) curve.

Results: Results indicated a significant difference in IL-33 and Leptin hormone levels among the study groups, which increased with increasing age, BMI, and duration of the disease. Both biomarkers showed highly significant differences in such disease and represented a risk factor. Leptin was illustrated to be a three-time risk factor for Rheumatoid arthritis disease compared to IL33. AUC analysis for IL-33 as a diagnostic parameter showed that IL-33 performs well in predicting such cases.

Conclusion: This study confirms a significant association between elevated leptin and IL-33 levels in RA patients, with leptin showing a three-fold higher risk than IL-33. Both biomarkers increase with age, BMI, and disease duration, highlighting their potential role in RA progression and diagnosis.
