Selective uranyl ion-imprinting with clickable amidoxime-functionalized pullulan.

Manufacturing a highly effective sorbent for removing UO ions from aqueous effluents is vital for safeguarding the environment and recovering valuable resources. This research presents an innovative strategy employing adsorbents derived from pullulan, specifically tailored with furfuryl-amidoxime (FAO), to improve their affinity for UO ions. The formation of a UO ion-imprinted sorbent (U-II-P) was achieved by crosslinking the UO/FAO-modified pullulan (FAO-P) complex with bis(maleimido)ethane (BME) via click Diels-Alder (DA) cyclization, enhancing its attraction and specificity for UO ions.

Ion-imprinted aminoguanidine-chitosan for selective recognition of lanthanum (III) from wastewater.

Developing a sorbent for the removal of La ions from wastewater offers significant environmental and economic advantages. This study employed an ion-imprinting process to integrate La ions into a newly developed derivative of aminoguanidine-chitosan (AGCS), synthesized via an innovative method. The process initiated with the modification of chitosan by attaching cyanoacetyl groups through amide bonds, yielding cyanoacetyl chitosan (CAC).

Antimicrobial Evaluation of Sulfonamides after Coupling with Thienopyrimidine Coplanar Structure.

This work describes the design and synthesis of three series of hybrids of thienopyrimidines and sulfonamides. Dihydrofolate reductase enzyme was selected as a target for the in-silico screening of the synthesized thienopyrimidine-sulfonamide hybrid as an antibacterial, while squalene epoxidase was selected as an antifungal target protein. All screened compounds showed promising binding affinity ranges, with perfect fitting not exceeding 1.

Pericardial Effusion as a First Manifestation of Rheumatoid Arthritis: A Case Report.

Rheumatoid arthritis (RA) is a systemic autoimmune disease that mainly affects the joints, which can lead to joint deformity. Since the disease is systemic, it affects many organs, including the heart, which can lead to pericarditis, coronary artery disease, and heart failure. We are reporting on a male patient, 34 years of age and Sudanese, who complained of shortness of breath and chest pain that started weeks before he came to the hospital, with no other associated symptoms.

Infective Endocarditis Caused By Streptococcus pluranimalium: A Case Report.

Infective endocarditis (IE) refers to an infection of the endocardium that can be caused by bacteria, viruses, or fungi. It can manifest either acutely or sub-acutely. Which can be complicated to stroke and congestive heart failure.
