The laboratory experiment was conducted in the laboratories of the Musayyib Bridge Company for Molecular Analyzes in the year 2021-2022 to study the molecular analysis of the inbreed lines and their hybrids F1 to estimate the genetic variation at the level of DNA shown by the selected pure inbreed lines and the resulting hybrids F1 of the flowering gene. Five pure inbreed lines of maize were selected (ZA17WR) Late, ZM74, Late, ZM19, Early ZM49WZ (Zi17WZ, Late, ZM49W3E) and their resulting hybrids, according to the study objective, from fifteen different inbreed lines with flowering time. The five inbreed lines were planted for four seasons (spring and fall 2019) and (spring and fall 2020) in the spring season 2019 the inbreed lines were crossed and flowering time were recorded and in the fall season 2019 they were crossed according to the study objective (late × late), (late × early) and (early) × late) and (early × early) in the third season, The results indicated that the two initiators used with the target flowering gene are highly efficient in diagnosing genetic variations and genetic divergence between the selected inbreed lines and their resulting hybrids F1 according to the different flowering time using PCR Poly Chain Reaction and Gel electrophoresis techniques. ) and the fourth hybrid (early×early) was superior in most of its field traits. It was found that inbreed line No. 15 (ZA17WR) did not show any bands in the interaction of the PCR and the flowering gene, and this is evidence that this inbreed line is counted as being optimal for the target gene and therefore genes or genetic sites may influence the early or delayed flowering time trait Therefore, it needs future studies. The aim of the current study is to know the genetic structures that contain the flowering gene and according to the planting date, whether fall or spring, to take advantage of those results in choosing and determining the appropriate and most appropriate method in the maize crop breeding programs to obtain promising genetic structures in terms of flowering time, whether was early or late. Additionally using two techniques to gather leads to increase the usefulness of these two techniques as the number of examined hybrids and inbred lines continues to increase rapidly.
Wastewater recycling for non-potable uses has gained significant attention to mitigate the high pressure on freshwater resources. This requires using a sustainable technique to treat natural municipal wastewater as an alternative to conventional methods, especially in arid and semi-arid rural areas. One of the promising techniques applied to satisfy the objective of wastewater reuse is the constructed wetlands (CWs) which have been used extensively in most countries worldwide through the last decades. The present study introduces a significant review of the definition, classification, and components of CWs, identifying the mechanisms controlling the removal process within such units. Vertical, horizontal, and hybrid CWs
... Show MoreInherited metabolic disorders (IMDs) are a diverse group of hereditary abnormalities that leads to a defect in metabolic pathway. Its diagnosis has been transformed by the innovations of molecular genetics and computational biology. Conventionally, diagnosis of IMDs is dependent on clinical findings and biochemical tests. Yet, these methods are limited due to a heterogeneity of such disorders and a large number of genes involved. The main objective of this review is to highlight the role of next-generation sequencing (NGS), including targeted gene panels, whole-exome sequencing (WES), and whole-genome sequencing (WGS), in the diagnosis of IMDs and providing reliable information in identifying genetic causes, and to explore the integrated an

Show MoreIntroduction: Trichophyton indotineae has emerged globally as a highly contagious, terbinafine-resistant dermatophyte causing treatment-refractory superficial mycoses, posing a significant public health threat.This study evaluated the epidemiology of dermatophytosis in Babylon Province, Iraq, and performed molecular identification and phylogenetic analysis of local clinical isolates. Methods: Clinical specimens from 258 patients aged 1 to 71 years were analyzed. Following phenotypic characterization, genomic DNA was extracted from three representative isolates. Polymerase chain reaction amplified the internal transcribed spacer region, followed by DNA sequencing and neighbor-joining phylogenetic analysis. Results: Tinea corporis was

The present study aimed to diagnose M. canis via the molecular method and differentiating its local Iraqi isolates from global isolates. Microscopic examination showed 55 specimens with M. canis from 130 specimens collected from children aged between 4-10 years suspected of dermatophytes who attended Medical City Laboratories and Baghdad Hospital in Baghdad city from 1/12/2022 to 1/3/2023. The results showed that the frequency of M. canis infections was 55/130 (42.31%). The results demonstrated significant differences in the animals' contact (p <0.0001), lesions (0.03) and habitation area (p =0.002). Whilst
... Show MoreHepatitis B virus (HBV) remains one of the most pervasive viral threats worldwide, posing a significant risk to millions. Due to the absence of proofreading activity during reverse transcription, HBV exhibits a high genetic variability. To date, ten distinct HBV genotypes have been identified globally, associated with varying disease outcomes, including progression to cirrhosis and carcinoma, as well as responses to antivirals. Consequently, genotypic analysis and molecular characterization of HBV are critical for optimizing therapeutic strategies. This study aimed to investigate the distribution of HBV genotypes among Iraqi patients and to characterize their molecular profiles. Therefore, a modified protocol was used to improve seq

SLE is a severe, systemic autoimmune disease characterized by autoantibody generation, complement activation, and immune complex deposition. In the pathophysiology of SLE, cytokines have a pleiotropic function. Recently, IL-9 was discovered to mediate strong anti-inflammatory effects in numerous cells or experimental autoimmune models. Objective This study aimed to determine the role of age, IL-9 serum level and genetic polymorphism, C-reactive protein (CRP), Anti-nuclear antibody (ANA) and Anti- double-stranded DNA (anti-dsDNA) to recognize SLE pathogenesis.
... Show MoreThis research attempts to find the association between single nucleotide polymorphism (SNP) of IL2+166 gene (rs2069763) and type 2 diabetes mellitus (T2DM) in a sample of Iraqi patients. A total of 44 patients and 55 apparently healthy volunteers were genotyped for the SNP using polymerase chain reaction test. Three genotypes (GG, GT, and TT) corresponding to two alleles (G and T) were found to have SNP. Both study groups’ genotypes had a good agreement for the analysis of Hardy-Weinberg Equilibrium. The results revealed increased frequencies between the observed and expected GG and TT genotypes and IL2+166 SNP T allele in T2DM patients (40.9 vs. 40.0 %; OR = 1.04; 95% CI, 0.47 - 2.31), whereas the values in the control group were
