The current study aimed to find the relationship between excessive addiction to electronic games and its effect on anxiety and stress hormones and some biochemical variables in groups of young people and adolescents∙ The experiment was conducted from the beginning of October 2024 until the end of December 2024∙ Samples were collected from schools, some entertainment places and gaming halls designated for electronic games in the city of Samarra∙ 90 blood samples were collected and divided into two groups: (30) samples from young people and adolescents, which is the control group, who do not play electronic games, and 60 samples from young people and adolescents, which is the non-control group, who play electronic games∙ The results showed a significant difference (P≤0∙05) in the concentration levels of glucagon and cortisol in the group of patients compared to the healthy group∙ There was no significant difference (P≤0∙05) in the concentration levels of insulin, adrenaline and acetylcholinesterase in the group of patients compared to the healthy group.

This study aimed to identify bacterial isolates from the Tigris River in Samarra using molecular techniques. The results revealed bacterial species from the genera Escherichia, Enterobacter, Aeromonas, Klebsiella, and Pseudomonas. Identification was confirmed via 16S rRNA sequence analysis, showing high similarity (97–100%) with reference strains in the NCBI database. Point and insertion mutations were particularly noted in Klebsiella pneumoniae and Pseudomonas aeruginosa, suggesting environmental stress. The study highlights the value of molecular tools in environmental monitoring and emphasizes the need for continuous water quality assessment due to the potential presence of multidrug-resistant bacteria suggesting the influence of environmental stress and pollution on the genetic structure of these bacteria.

The antimicrobial activity of suspensions extracted from two fungal species, Agaricus bisporus and Pleurotus ostreatus, and a date palm leaves extract after adding a nanomaterial made of AgNO3 was tested against two Gram-negative bacteria, Klebsiella pneumoniae and Proteus mirabilis. The result showed that the highest antimicrobial activity was reported in the suspension extract from Agaricus bisporus, followed by the palm leaves extract. In contrast, the lowest antimicrobial activity was observed in the suspension extract from Plerotus ostreatus. The extracts used in this research had a significant effect in inhibiting and limiting bacterial growth, in addition to the effect played by fungal suspended.

The purpose of this study was to ascertain how oral administration of 30% and 40% chitosan nanoparticles on bisphenol-A affected the lipid profile, renal function, and liver enzyme parameters (ALT, AST, and ALP) in white male rats. The liver enzyme markers AST, ALT, ALP, urea, creatinine, triglycerides TG, cholesterol TC, low-density lipoprotein LDL, and very-low-density lipoprotein "vLDL" were all significantly elevated (p < 0.05) by bisphenol-A, while the concentration of high-density lipoprotein HDL decreased. While a significant decrease was observed in the parameters of liver enzymes, urea, creatinine, triglycerides (TG), cholesterol (TC), low-density lipoprotein (LDL), and very-low-density lipoprotein (vLDL) and an increase in the value of high-density lipoprotein (HDL) when treated with chitosan nanoparticles.

The current study this study investigated the postnatal stages of female sheep were taken the ovary of healthy females, the age of the animals was determined depending on formula of milk teeth and eruption age of teeth. Across two age groups: 2–3 months age and 8–9 months age. In the first group (2–3 months), the ovarian structure lacked clear distinction between cortex and medulla, the germinal epithelium comprised a single layer of cuboidal to low columnar cells, overlying a moderately thick tunica albuginea made of dense connective tissue. The ovarian cortex displayed numerous primordial follicles beneath the tunica albuginea, each containing an oocyte surrounded by flattened granulosa cells. Early primary follicles with an enlarged oocyte and cuboidal granulosa cells were also observed. Occasional secondary follicles appeared with multiple granulosa layers and early thecal differentiation, but no antral cavities, indicating preantral development. The medulla contained loose connective tissue, fibroblasts, and numerous developing blood vessels. In contrast, in the second group (8-9month) which lambs exhibited clear compartmentalization into cortex and medulla. With surface lined by a simple squamous to low cuboidal germinal epithelium underlain by a thick collagen-rich tunica albuginea. The cortex contained follicles at all developmental stages, including primordial, primary, secondary, and Graafian. The medulla featured dense connective tissue, fibroblasts, and vascular networks.

In this study, which was conducted on the Tigris River in Salah al_Din Governorate at five stations (Al_Dhuluiya, Al_Alam, Al_uwainat, Balaj Tikrit, and Baiji) the differences were identified through morphological and anatomical comparisons of the following species: Typha domingensis, Eichhornia crassipes, Nasturtium officinale, using the electron microscope. The study included the anatomy of cross sections of the stem of the studied species .The results showed a difference in the internal structure of the stem, especially in the cortex area, as the cortex in Eichhornia crassipes contained a much larger aerial tissue than Typha domingensis, species, which contained a larger aerial tissue than the Water hyacinth species Nasturtium officinale .The morphological study included the shape of the stem, The stem of Typha domingensis plant is cylindrical and straight, reaching a length of about 1-3 meters, and most of its types are unbranched. As for the stem of Eichhornia crassipes plant, it is short, reaching a length of about 10 cm, while the stem of Nasturtium officinale plant is about 60 cm long.

The study aimed to identify (22)species belonging to the (Cyperaceae )family in Iraq ,the study included determining the environment and distribution of the species, and showed a noticeable variation in their distribution within the Iraqi provinces, Cyperus fiscus appeared widely spread throughout the Iraqi provinces , which appeared in 6 provinces :((MAM ,FKI,LCA,LEA,MCU,DGA), while C.conglomeratus ratt, C.ucheri, Cyperu leavigatus and Acorellulaeviglu were commen species ,with each species spreading to only one province, the other included B.tuberosus dest ,Cyperus rotundus, C.longus, C.difformis L was spread across different Iraqi provinces, the data were entered in a table that included the species under consideration , Iraqi provinces and soil type environment.
