ABSTRACT

Globally, diabetes mellitus (DM) disease is one of the main causes of death. Type-2 diabetes mellitus (T2-DM) cannot be cured by first-line medications, and long-term use carries a significant risk of serious side effects. Novel antidiabetic agents with high efficacy are required. In the T2-DM rats’ model, the anti-diabetic effect of Rhopilema nomadica venom (RNV) and R. nomadica umbrellar extracts (RNUE) was assessed. Biometric and biochemical measurements were determined. The median lethal doses (LD50) of RNV and RNUE were estimated, and then Sprague Dawley male rats were split into five groups (n=10) as follows; group 1 (Gp1) served as a negative control. Gp2 to Gp5 were given a high-fat diet (HFD) and then, injected with STZ (30 mg/kg) interperitoneal (i.p.). Gp2 was kept as diabetic rats (T2-DM rats). Metformin (Met) (150 mg/kg), RNV (7.5 mg/kg), and RNUE (14.4 mg/kg) were given to Gp3, Gp4, and Gp5, respectively. All treatments were taken i.p., once every day for eight weeks body weight (b.wt) changes, the levels of glucose, C-peptide, biochemical parameters, and the histopathological alterations were assessed. R. nomadica diameter was 35- 40 cm, and its weight was 4- 4.5 kg. RNV and RNUE total antioxidant capacities were 2.39 ± 0.18 and 2.92 ± 0.26 mg/g. RNV and RNUE protein profiles showed eight and seven bands. Treatment of T2-DM rats with Met or RNUE led to a hypoglycemic effect as indicated by improvement of b.wt changes, glucose, C-peptide levels, hepato-renal function, antioxidant/oxidant biomarkers status, and insulin-secreting β-cells in the pancreatic islets.

Abstract

Background and Objective: Patients receiving liver transplantation are more likely to develop a wide range of infectious complications such as Helicobacter pylori (H. pylori).This study aims to assess the prevalence of H. pylori in individuals receiving liver transplants through the lymph nodes. Moreover, to investigate the relationship between the polymorphisms in the IL-1βgene and the H. pylori infection.

Methods: A total of 43 liver-transplanted patients were selected. They performed a history interview and physical and biochemical examination. The UreA gene and the virulent gene CagA were molecularly screened from paraffin-embedded tissue, additionally, the polymorphism of IL-1β was performed by Polymerase Chain Reaction-Restriction length polymorphism (PCR-RFLP).

Results: all 23(53.5%) patients showed H. pylori infection with UreA gene detection. Out of them 8 (34.8%) were positive for the CagA virulence gene. The infected group with H.pylori showed a significant decrease in albumin (P<0.05). In the case of CagA-positive patients showed a significant decrease in albumin, urine creatinine, HB, platelets, total calcium, and AT III and an increase in urea, creatinine, uric acid, iron, INR, K, TSH, LDH, triglyceride, lipase, and amylase. Analysis of IL-1β (C+3954T), the TT genotype is considered a protective factor, while the CT genotype might be a risk factor for infection. Concerning IL-1β (T-31C) in the case of CagA positive C allele might be protective from infection with CagA-positive strain.

Conclusion: Based on these results, H. pylori appears to have a significant impact on the progression of liver transplanted patients with an interference role of IL-1β polymorphism.

ABSTRACT

Hydroxyapatite nanoparticles are regarded as an inorganic constituent found in natural bone and are primarily employed in tissue engineering because of their exceptional biocompatibility and bioactivity. Nevertheless, it remains uncertain whether they are safe for medical applications owing to their petite nano-scale particle size. From the previous studies, there was not enough data on nephrotoxicity and molecular changes induced by (high or low HAP-NPs) and the protection role of nano-antioxidants (CurNPs) in minimizing their toxicity. Therefore, the present study aimed to investigate the effect of high and low doses of HAP-NPs on the kidney system in male rats. At the molecular level, these results presented that the gene expression level, high HAP-NPs alone caused a significant increase in both kidney Injury Molecule-1 (KIM-1) and Lipocalin-2 (LCN-2) genes also, caused a significant increase in oxidative DNA damage (8-OHdG). The presence of Curcumin nanoparticles minimized the toxicity of high or low HAP-NPs due to their antioxidant properties and scavenging abilities against active free radicals.

Abstract

Type 2 diabetes mellitus (T2-DM) is a chronic metabolic disorder characterized by tissue resistance to insulin action. Leiurus quinquestriatus venom (LQV) contains a variety of bioactive components that can be used for the treatment of various diseases. This study aimed to determine the ameliorative role of LQV on the histopathological changes in splenic tissues of T2-DM rats. Forty male Sprague Dawley rats were divided into 4 groups (n = 10) as follows; Gp1 (Control group) was fed on a normal balanced diet. Gp2 (Diabetic group) was fed on a high-fat diet (HFD) for 12 weeks and then injected with streptozotocin (STZ) (30 mg/kg) i.p. Diabetic Gp3 and Gp4 groups had been injected with metformin (Met) (150 mg/kg) or LQV (1/10 of LD50), respectively. After two months of treatment, the total body weight relative splenic weight changes, and blood glucose. Also, histopathological and immunohistochemical investigations (CD-3 immunoreactive antibody) in splenic tissues were examined. The results showed that induction of T2-DM in rats led to a significant decrease in the total body weight (-38.56%), relative spleen weight (0.23 ± 0.03), and increase in the level of blood glucose (382.56 ± 2.77 mg/dL). In addition, several histopathological and immunohistochemical changes were observed in splenic diabetic tissues. The treatment of T2-DM rats with LQV led to an improvement in the total body weight of rats (4.07%), relative spleen weight (0.40 ± 0.02), decrease in the blood glucose levels (115.47 ± 1.07 mg/dL), ameliorated the histopathological and immunohistochemical changes occurred in splenic tissues of T2-DM rats.

Abstract

Background: investigate the enzymatic activity of Myeloperoxidase (MPO) in pre-diabetic and diabetic individuals and explore the modulation of this activity by taurine supplementation, considering its potential anti-oxidative properties and the emerging evidence of its role in glucose metabolism. Methods: This case-control study was done at the Iraqi University College of Medicine. It used advanced spectroscopic techniques and kinetic modeling to measure the amount of MPO activity in the sera of people who were healthy, pre-diabetic, and diabetic. The Lineweaver-Burk plot derived from the Michaelis-Menten equation was used to ascertain the Km and Vmax of MPO. Taurine inhibition assays were also performed to understand its effect on MPO kinetics. Results: The data showed that MPO activity increased significantly from the control group to the diabetic group. This was in line with rising HbA1c levels and BMI, suggesting a link between MPO activity, glycemic control, and obesity. The gender distribution showed no significant deviation, suggesting that the observed enzymatic and metabolic alterations are not gender biased.

Conclusion: The pronounced elevation in MPO activity in diabetic individuals underscores the enzyme’s potential significance in glycemic diseases. The results mean that more research needs to be done on how taurine, which is known to have anti-inflammatory and antioxidant properties, could improve MPO activity and possibly restore metabolic homeostasis, opening a new way to treat type 2 diabetes.

Abstract:

Background: The emergence of resistance to numerous novel antibiotics, which serve as the ultimate resort for treating infections caused by Gram-negative bacteria that are resistant to multiple drugs, poses a significant risk to public health. The Citrobacter freundii strain obtained from the burned skin of an adult exhibited resistance to a broad range of antibiotics, including colistin. The genome features that underlie the antibiotic-resistance phenotype of this isolate was characterized using whole genome sequencing (WGS). Methods: Genome sequencing on the Illumina platform was performed on the provided DNA samples (reference order number HN00194138; Psomagen/USA). The assembled genome was assembled and annotated by PATRICS. Results: The average G+C content was 55.75 percent throughout the 113 contigs in the genome. There are 9,825 protein-coding regions (CDS) in this genome, along with 149 transfer RNA (tRNA) genes and 8 rRNA genes. There were 1,584 putative proteins annotated and 8,241 proteins with known functions. PATRICS can identify 1592 hypothetical proteins. Additionally, 2132 proteins were displayed together with 8233 protein assignments under functional proteins.

Conclusion: The Iraqi multidrug-resistant C. freundii strain has not been reported before. These genetic findings help explain C. freundii’s pathogenicity. Genomic analysis has helped us comprehend the probable resistance mechanism and the isolates’ phylogenetic link with public-domain draft genomes.

Abstract:

Heart failure has been considered in the last few years as a major factor in global mortality. Heart failure is known as the reduced ability of the heart muscle to fill or/and to pump adequate blood. Finding a diagnostic biomarker is necessary to help in the early diagnosis of heart diseases. MicroRNAs are new biomarkers that have been used for early diagnosis of various diseases. The work aims to study miR-34a in patients with heart failure and assess its diagnosing role. In this work, a total of (120) subjects were divided into three groups as the following, the control group (n=20) of healthy individuals, group II (n=50) the patients with heart failure post myocardial infarction & group III (n=50) the patients with heart failure without myocardial infarction history. microRNA-34a expression showed high expression and significant elevation (P- value < 0.5) in group-II (31.67±11.8 fold) and group-III (27.31±12.4fold) compared with group-I (1.47±0.7 fold). Our results showed that microRNA-34a plays a critical role in patients with heart failure disease and can be used as a biomarker for the diagnosis of early stages of heart failure disease.

Abstract:

Introduction: Every year in the world, 530000 women die from causes related to maternity, 4000000 infants die in the neonatal period, and the same number of stillbirths are born, especially in the Middle East and Morocco, the millennium development goals of reduction.

Objective: a meta-analysis based on literature studies on the health status, maternal, and neonatal child, mortality, and its causes in the Middle East and Morocco.

Method: 617 articles in the databases (189, 177, 113,101, and 37 articles obtained in Scopus, Elsevier, PubMed, Google Scholar, and other engines).

Results: The maternal mortality rate recorded in Yemen is the highest, reaching 8.900% in 2019, the percentage was the lowest in all of Lebanon, Iran accounted for 0.023% in 2018. The neonatal mortality rate was the highest in Iraq it reached 32.10% in 2022, and the death rate was the lowest in Egypt at 5.00%. The child mortality rate was the highest in Syria (23.1%) in 2021, and Jordan had the lowest (6.7%) in 2022. The policies seek to reduce maternal, neonatal, and child mortality by increasing health awareness, health care quality, competencies of equipment, supplies, manpower, and media for education and recording epidemiological data. Morocco and Turkey, in 2030 seek to reduce MMR to 71 deaths per 100,000 births.

Conclusion: The health policies followed in the countries limit the rise of maternal, neonatal, and child mortality rates, hence the importance of conducting more studies and in-depth research and applying future policies and strategies to reduce the mortality rate.
