The widespread use of imidacloprid (IMI) in pest control presents significant environmental challenges due to its persistence and low removal efficiency. This study introduces magnetic Covalent Organic Frameworks (COFs) functionalized with Fe₃O₄ nanoparticles (Fe₃O₄@HMN-COF, Fe₃O₄@MAN-COF, and Fe₃O₄@SIN-COF) as efficient adsorbents for IMI removal from water. These COFs, engineered with nitrogen-rich structures and extensive π-electron systems, achieve superior adsorption through π-π interactions, hydrophobic interactions, and hydrogen bonding.

Limited data are published in critically ill paediatric patients, especially from the Middle East. We aim to investigate haemodynamic effects and incidence of hypotension with intravenous acetaminophen in critically ill children, with a focus on understanding factors influencing these effects.

Iodine, a potentially harmful byproduct of uranium fission, is hazardous to both the environment and human health. Therefore, developing safe, effective, and affordable storage facilities for iodine waste is crucial.

Plants that exhibit antioxidant properties have shown promising anticataract effects, likely because they supplement the activity of glutathione, the major antioxidant in lens cells. An extract of Cleome rupicola, a desert plant found in the United Arab Emirates, has traditionally been used to treat cataracts.

The effects of synthesized compounds on regulating glucose metabolism, improving insulin sensitivity, and activating the peroxisome proliferator-activated γ receptor (PPAR-γ) were evaluated in βTC6 cells. Compounds TZDs # , , , and reduced the basal insulin secretion by ∼20.

No descriptive analysis highlights the threat of antimicrobial-resistant (AMR) of among livestock in the United Arab Emirates (UAE). Herein, we conducted phenotypic and genotypic resistance studies on isolates from livestock samples in the Emirate of Abu Dhabi based on routine diagnosis between the periods 2014-2019.

Knowing that the tyrosine phosphatase SHP2 is a regulator in tumorigenesis, developing inhibitors of SHP2 in breast cells is crucial. Our study investigated the effects of new compounds, purchased from NSC, on the phosphatase activity of SHP2 and the modulation of breast cancer cell lines' proliferation and viability.

The prepared pyrimidine GLP-1 agonist used for the treatment of diabetes type II, was trapped inside polymer coated ZIF-8. The encapsulation of the GLP-1 agonist was confirmed by UV-visible and FT-IR spectroscopies.

In this study, we report a case of a 5-year-old girl with new onset of insulin-dependent diabetes mellitus, who presented with severe diabetic ketoacidosis associated with brain edema and severe myocardial dysfunction, needing intubation and inotropic support. To our knowledge, this is the youngest reported case with severe diabetic ketoacidosis complicated with myocardial dysfunction.

In this study, two series of new pyrimidine derivatives were designed and synthesized using an efficient route, and were evaluated in terms of GLP-1 receptor agonist activity. In the first series, novel pyrimidines substituted at positions 2 and 4 with groups varying in size and electronic properties were synthesized in a good yield (78-90%).

A new series of substituted 2(1H)-pyridones (4a-i) and their glucosides (5, 6a-e) were prepared as potential agents against leukemia (HL-60) cells. Glucosides (5,6a-e) were synthesized using three independent methods. Microwave protocol as an ecologically new method was used to synthesize the target compounds.
