Aryl Hydrocarbon Receptor Modulation Impacts on the Blood-testis Barrier Integrity via TJP1 Function
...Show More Authors

Background: Male infertility is a global concern and it tends to increase due to miscellaneous factors, such as environmental toxins and genetic and lifestyle choices. The aryl hydrocarbon receptor (AHR) has recently attracted attention due to its involvement in male infertility mechanisms and impact on sperm production and function. AHR, a versatile receptor expressed in various tissues, including the testes, regulates the genes involved in spermatogenesis. AHR activation is associated with cell cycle regulation and chromatin condensation during spermatogenesis. Objectives: This study aimed to investigate the influence of AHR activation on blood-testis barrier (BTB) integrity, focusing on the role of tight junction protein-1 (TJP1) and exploring the effects of AHR modulation on spermatogenesis outcomes in adult male rats. Methods: Forty adult male rats were divided into four groups according to their treatment regimens. Briefly, the control group was kept without any treatment, the resveratrol (RES) group received an intraperitoneal (IP) injection of 100 mg/kg every 72 h and the AHR antagonist (AHR‾) group received an IP injection of CH223191 at a dose of 10 mg/kg every 72 h. Finally, the dimethyl sulfoxide (DMSO) group received DMSO which was used as a solvent for preparing RES and CH223191. The study lasted for 60 d to cover the entire spermatogenesis cycle. At the study’s endpoint, sperm chromatin maturity and condensation were evaluated in addition to Tjp1 gene expression in testicular tissue, supported by BTB integrity assessment. Results: The abnormal sperm chromatin maturity (ASCM) and condensation were significantly (P<0.05) higher in AHR‾ compared to all other groups. Tjp1 gene expression was significantly upregulated in the RES group compared to the control and AHR‾ group, which tightened the BTB and maintained the testicular homeostasis for normal spermatogenesis. Conclusion: RES treatment positively influenced sperm chromatin maturity, Tjp1 expression and BTB integrity, suggesting its potential as a protective agent against male reproductive health. Conversely, AHR antagonism leads to compromised sperm chromatin integrity and BTB function, highlighting the critical role of AHR in spermatogenesis and BTB maintenance. These results underscore the importance of AHR modulation in male fertility and provide insights into potential therapeutic interventions.

Effect of Hyper and Hypothyroidism on Lipid Profile and Liver Function of Male Rats
...Show More Authors

This study was designed to investigate the effect of thyroid hormone disturbance on lipids profiles and liver functions. Eighteen mature male rats Rattus norvegicus were divided into three groups. The first and the second groups were injected subcutaneously with thyroxine (T4) and carbimazol (both at 600 µg/kg BW) respectively on alternate days, to produce recurrent periods of hyper and hypothyroidism .The control group which is the third group was injected with physiological saline. The process continued 4 weeks, after that, injection, blood specimens were collected to estimate serum levels of T3 and T4, Total cholesterol (TC), Triglycerides (TG), High density lipoprotein cholesterol (HDL-C), Low density lipoprotein cholesterol (LDL-C) an

A New Methodology to Find Private Key of RSA Based on Euler Totient Function
...Show More Authors

          The aim of this paper is to present a new methodology to find the private key of RSA. A new initial value which is generated from a new equation is selected to speed up the process. In fact, after this value is found, brute force attack is chosen to discover the private key. In addition, for a proposed equation, the multiplier of Euler totient function to find both of the public key and the private key is assigned as 1. Then, it implies that an equation that estimates a new initial value is suitable for the small multiplier. The experimental results show that if all prime factors of the modulus are assigned larger than 3 and the multiplier is 1, the distance between an initial value and the private key

Effects of Ionized Water on Certain Egg Quality Traits and the Levels of Proteins and Enzymes in the Blood of the Japanese Quail Coturnix japonica
...Show More Authors

Objective: This experiment was conducted to study the effects of ionized water on certain egg quality traits and the levels of proteins and enzymes in the blood of the Japanese quail Coturnix japonica . Materials and Methods: One hundred 42-day-old quail were randomly distributed among five treatment groups with four replicates for each group. The following treatments were used: T1 (control): The birds were provided normal water, T2: The birds were provided alkaline water (pH = 8), T3: The birds were provided alkaline water (pH = 9), T4: The birds were provided acidic water (pH = 6) and T5: The birds were provided acidic water (pH = 5). A Complete Randomized Design (CRD) was used to investigate the effects of the studied treatments on diffe

Relationship between Lipid Peroxidation and Integrity of Sperm Plasma Membrane in a Sample of Iraqi Infertile Men
...Show More Authors

The current study aims to investigate the relationship between lipid peroxidation, represented by seminal malondialdehyde (MDA) level, and integrity of sperm plasma membrane, represented by the hypo-osmotic swelling (HOS) test score, in infertile men. One hundred and twenty Iraqi men (20 fertile and 100 infertile) shared in this study during their attendance to the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies/Al- Nahrain University. The mean age of the fertile men was (30.46±0.78) years while the mean age of infertile men was (32.58±0.64) years with the duration of infertility (5.36±0.33) years. Semen samples were collected and the parameters of seminal fluid analysis were assessed; also, the HOS

Impact of Plasma Focal Adhesion Kinase, Ephrin Receptor Type A4, and Adiponectin in Patients with Acute Myeloid Leukemia
...Show More Authors
Abstract<sec> <title>BACKGROUND:

Focal adhesion kinase (FAK), ephrin receptor type A4 (EphA4), and adiponectin (ADPN) are important indicators in inflammation, tumor growth, migration, and angiogenesis in some cancers. The predictive impact of their concentrations in acute myeloid leukemia (AML) patients to be identified remains. The research sought to explore the effect of FAK, EphA4, and ADPN as prognostic biomarkers, and their influence on patient survival, and to look for any potential correlation between their levels with hematological parameters in AML patients.
