The significance of four soil treatments on basil growth and soil chemistry was analyzed at GC-MS: vermicompost (VC), bitmoss (BM) and VC+ sandy soil, and VC+ bitmoss. The GC–MS analysis determined that VC contained 29.2% stearic acid and 21.5% 2,4-dimethylphenol, and BM had a 20% humic acid. VC treated with 250 mL VC + sandy soil showed the highest positive influence on basil growth, resulting in the tallest (20 cm) and the biggest leaves (5 cm) were produced by the plants. In contrast, BM alone had slow growth response (5 cm) although being a product with humic acid for its fraction. The presence of BHT(T) (15.7%) in the VC + soil treatment indicated potential contamination. These results indicate that VC mixed with sandy soil provides ideal conditions for basil growth, possibly as a result of enhanced soil physico-chemical properties and nutrient availability.

The purpose is to compare the efficacy of various hand rub brands against specific skin-colonizing bacteria due to the widespread use of hand disinfectants, due to COVID-19's contagious nature, highlighting the importance of hand hygiene in reducing nosocomial infections and cross-transmission. Thirty workers from the Iraqi Scientific Research Commission’s laboratories, split into two groups for administrative and scientific work to provide bacterial samples. A total of thirty samples of bacteria were acquired. Based on their popularity and frequent use in Baghdad, fifteen different hand sanitizers from various brands were purchased for this study. The well diffusion agar test was used in the experiment to assess the bacterial activity of the hand sanitizers used in the study. The majority of sanitizers were unable to eradicate every type of bacterial species identified during the study. The gel sanitizer with 93% ethyl alcohol was successful in eliminating every bacterial strain identified, except for one species. Meanwhile, a liquid sanitizer with 70% alcohol was unable to eradicate even a single strain of bacteria. Our study's findings demonstrated that the alcohol-free disinfectant outperformed the sanitizer with an alcohol content ranging from 60 to 93% in terms of bacterial control.

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.
