Background: Cholestatic Jaundice is a dilemma facing not only the primary care provider but also the specialist pediatricians in our country.
Subjects & methods: Analysis of 50 cases of cholestatic jaundice aged 3 weeks- 18 months were carried out over 18 months in the Gastroenterology & Hepatology unit in the Children Welfare Teaching Hospital, Medical City, and Baghdad. Clinical, biochemical, radiological and histopathological results were recorded.
Results: Fifty patients with Cholestatic Jaundice, 28 males &22 females, were evaluated. The main causes of Cholestatic Jaundice were Biliary Atresia in 22 cases (44%)(the mean age of presentation was 4.1 months ), and Neonatal Hepatitis Syndr

The acute and sub chronic toxicity effects of 25.16 nm intraperitoneally- injected zinc oxide nanoparticles (ZnO NPs) were evaluated. Albino male mice were exposed to three different doses (25, 50 ,and 100 mg/kg ), depending on the value of calculated LD50, for 2 and 4 weeks . Considerable changes in organ indexes were shown with a good relevance to the illustrated histopathological effects which ranged from multiple hemorrhagic foci in liver, mild swelling and dilatation in kidney tubules, thickening of intestinal villi, moderate interstitial pneumonia, especially with the high dose , and sever necrosis of seminiferous tubules in testes of all studied groups. Significant changes in both hematological and biochemical parameters as well a

Lyophilized bromelain enzyme was obtained from the Department of Food Sciences, College of Agricultural Engineering Sciences, University of Baghdad. Some properties of the enzyme were determined, the optimum temperature and pH for activity and stability, as it used a range of graduated temperatures from 25 °C to 85 °C, as well as a range of pH degrees from 4 to 9. The results showed that the best pH for activity was 7, as it reached the enzymatic activity was 42.3 units/ml, and the best pH range for stability was 7-5. The best temperature for the activity was 45°C, as the enzymatic activity reached 59.3 units/ml, and the enzyme retained its full activity after being incubated at a temperature of 25 - 45 °C. The anti-browning en

Background: Interleukin-31 has been linked with developing and maintaining pruritus in various dermatological and non-dermatological diseases.

Objectives: To evaluate interleukin-31 serum levels in hemodialysis patients with and without uremic pruritus as a potential contributor.

Methods: This cross-sectional study involved ninety adult chronic kidney disease patients on hemodialysis. All of the enrolled patients were on a three-times/week hemodialysis regimen. Patients were divided into two groups of 45 patients each. Group 1 involved those with pruritus and Group 2 involved those free of pruritus; based on the itching severity scale (ISS). Serum levels of interleukin-31,

This study develops a nonlinear dynamic model for glucose-insulin regulation that includes glucose utilization, saturated insulin secretion, insulin clearance, and an auxiliary remote-effect variable capturing the delayed regulatory response. The proposed framework enables comprehensive investigation of glucose homeostasis from a dynamical systems perspective, emphasizing equilibrium structure, stability properties, and parameter-induced transitions. The positivity and bounds of the solution were established  ensuring the physical acceptability . Analytical characterization of the equilibrium points reveals that the steady-state   of glucose concentration satisfies a non-linear algebraic relationship, allowing parameter-dependent shif

Background: APACHE II is an abbreviation for the Acute Physiology and Chronic Health Evaluation scoring system that is frequently used to study the possibility of disease progression and predict the mortality risk in patients with critical illness.
Objectives: To analyze the outcomes of the Intensive Care Unit (ICU) at Ghazi Hariri Hospital for Surgical Specialties using the APACHE II scoring system.
Methods: From May 28 to August 28, 2025, a prospective cohort study took place. Included were (100) patients (≥18 years old) who remained for at least 24 hours at the ICU of Ghazi Hariri Hospital, Baghdad. The APACHE II scoring system was calculated for each pati

Amino glycoside derivation including, Neomycin, Streptomycin, Kanamycin and Gentamycin with special reagents, which  are  benzoylchloride; benzene sulfonyl chloride and phthalic anhydride were made to enhance Uv-detectability for HPLC analysis. But there are many problems facing pre column derivation and in order to solve this, the conductivity of antibiotic derivatives were used to calculate the dissociation constant and the hydrolysis rate which determined concern type reaction. In addition the  characteristics those controlling the hydrolysis of antibiotic-derivatives were investigated.

Background: Adenoidal hypertrophy is generally considered a common condition of childhood .When obstructive symptoms or recurrent otitis media (suppurative or non suppurative) occurs, adenoidectomy is generally indicated.A wide range of bacteria could be isolated from the surface and core tissue of the removed adenoid tissue.
Patients and Methods: A prospective study carried out in the ENT Department of AL-DIWANIYAH Teaching Hospital between October 2007 and September 2008.Involved 73 patients between 3 and 7 years, they were 31 male and 42 female .All patients underwent adenoidectomy .Surface and core swabs was taken from all specimens and submitted to bacteriological study.

Background : the major focus of respiratory cytology is the diagnosis of lung cancer , carcinoma of the lung is now reported to be the most commonly diagnosed non- Cutaneous malignancy in the world. Iraq has faced the increase in incidence of this lethal type of cancer. Sputum cytology is a convenient method of screening and diagnosing primary epithelial tumor of the lung which is of many types include fresh smear ,Sacccomanno smear, and mailing container method.
Methods : Sputum cytological study was done on 50 patients suspected to have pulmonary carcinoma prepared by fresh smear method ,Saccomanno method ,and mailing container
method.One, two,or three samples taken from each patient.Slides were prepared

The floristic survey of the Al-Muthana Desert recorded 74 species representing 27 families. Amaranthaceae was the most represented family, followed by Asteraceae and Poaceae, reflecting the prevalence of desert-adapted taxa. Species richness and diversity varied among the studied stations. St5 and St6 each contained 13 species, whereas St8 had the highest richness, with 24 species. The Shannon diversity index (H′) ranged from 2.370 to 2.880, and Pielou's evenness (J) ranged from 0.890 to 0.965. The consistently low dominance values (0.056–0.106) indicated relatively balanced plant communities. St8 exhibited the highest richness, whereas St5 and St6 exhibited the lowest. Euclidean distances indicated substantial differences among station

Background:

This paper proposes a hybrid learning-based navigation framework that integrates classical path planning with a spiking neural network model to achieve scalable and computationally efficient robot navigation in grid - based environments. Optimal reference trajectories are generated using the Spiking Wavefront Planner (SWP) over occupancy maps derived from the KITTI Odometry dataset. These expert paths are employed to train a Super Elman Spiking Neural Network (SE-SNN) using the e-prop learning rule to capture sequential navigation decisions. The framework is evaluated across map sizes ranging from 100×100 to 400×400 and compared with classical planners such as A* and D* Lite. Results show that the proposed SWP-SE-SNN model reduces plannin

Background: Methamphetamine (METH) is a potent synthetic stimulant that significantly impacts the central nervous system and can lead to severe liver damage. Prolonged METH use causes hepatocytes damage and fibrosis, marked by increased laminin deposition, a key component of the extracellular matrix produced by stellate cells during liver injury.

Objectives: This study aimed to investigate the effects of METH abuse on liver function and laminin (LN) levels, correlating these with the duration and concentration of METH use.

Methods: Conducted from January to August 2024, this case-control study involved 75 male participants with METH addiction (6-120 months of use) and 75 he
