Article Abstract
Transition metal ion complexes of a number of chelators have been widely investigated due to their biological properties. The sugar conjugation of metal complexes has resulted in improved properties of the systems, such as solubility and lectin recognition. In this paper, we report the synthesis, the characterization of new glucose and galactose conjugates of 1,4,8,11-tetraazacyclotetradecane (cyclam) and their Cu(II) complexes. The glycoconjugates were proved to be protective agents of metal-induced amyloid aggregation. The binding constants of the galactose conjugate KA1=(3.07±0.16)×10(7) and KA2=(2.13±0.04)×10(7)M(-1) with the lectin Ricinus communis agglutinin (RCA120) as a model of galactose-specific human lectin were obtained with surface plasmon resonance.

Objective: New therapeutic options have recently emerged for patients with highly active, acetylcholine receptor antibody-positive (AChR-Ab) generalized myasthenia gravis (gMG), including fast-acting, endplate-protective agents such as complement C5 inhibitors (C5-I) and neonatal Fc receptor inhibitors (FcRn-I). However, objective biomarkers beyond clinical scoring systems are lacking to guide individualized treatment decisions.
Methods: In this exploratory, prospective real-world study, we assessed serum calprotectin (sCLP) and serum neurofilament light chain (sNfL) levels in a total of 22 AChR-Ab gMG patients, who were treatment-naïve for either C5-I or FcRn-I.

Cystic fibrosis (CF) is a multifaceted disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The resulting thick mucus accumulation increases the risk of microbial infections, leading to chronic lung inflammation, progressive tissue damage, and pulmonary exacerbations (PEs). Respiratory viruses may facilitate bacterial colonization, significantly contributing to PEs.

Background: Acute upper gastrointestinal bleeding (AUGIB) is a critical medical emergency and is a common cause of illness and death in individuals with liver cirrhosis.
Objective: The point of this study was to check how well the albumin-to-bilirubin ratio (ALBI) and model for end-stage liver disease (MELD) scores could predict how these patients would do in the future.
Methods: The Imam Khomeini Hospital gastroenterology department conducted a retrospective examination.
