The influence of Ag2O/NbO2 nanocomposites on the optical properties of PVA/PVP lend in biomedical applications.

Objective: To study the optical properties of nanocomposites as well as antibacterial activity.

Methods: The experimental study was conducted at the University of Babylon, College of Science and College of Education for Pure Sciences, Babylon, Iraq, from September 2021 to February 2022. Impregnation of transparent matrix polyvinyl alcohol and polyvinyl pyrrolidone nanocomposites was done by silver oxide and niobium oxide nanoparticles.

Prevalence of bullying among pupils in Baghdad.

Objective: To find out the prevalence of bullying among primary school students in an urban centre, and to categorise its types.

Methods: The descriptive, cross-sectional study was conducted from October 1, 2018, to March 31, 2019, in Baghdad, Iraq, and comprised primary school children of either gender aged 9-15 years studying in schools in all the 3 directorates of the Al-Karkh side of the city. Data was collected through face-to-face interviews with the subjects, from school data, and through interaction with social-guide teachers of the respective classes.

The effect of serum uric acid concentration on the severity of chronic congestive heart failure.

This study aimed to investigate the adverse effects of serum uric acid concentration on the severity of chronic congestive heart failure. One hundred patients with chronic congestive heart failure (several risk factors include hypertension, smoking, and diabetes mellitus) were enrolled in this study (51 females and 49 males). Participants were admitted to Alsader Medical City in Al-Najaf from August 2018 to March 2019.

Enzymatic Effectiveness of Alcoholic and Aqueous Extract of in Mice Poisoned with Tetrachloride.

Regarding the antioxidant, anti-inflammatory, and antibacterial effects of () extracts and the use of medicinal herbs as an alternative to chemical drugs, this study aimed to evaluate the enzymatic changes and reduction of hepatocyte damage in mice poisoned with carbon tetrachloride (CCl4) after treatment with aqueous and alcoholic extract of . A total of 40 adult male mice were divided into eight groups including six experimental, one negative, and one positive control group, which were exposed to CCl4 at the concentration of 2.3 mg/kg.

Gold Nanoparticles and Graphene Oxide Flakes Enhance Cancer Cells' Phagocytosis through Granzyme-Perforin-Dependent Biomechanism.

The study aimed to investigate the roles of gold nanoparticles (GNPs) and graphene oxide flakes (GOFs) as phagocytosis enhancers against cancer cells. The nanomaterials were characterized through SEM and UV-VIS absorptions. The GNPs and GOFs increased the macrophages' phagocytosis ability in engulfing, thereby annihilating the cancer cells in both in vitro and in vivo conditions.
