Mannans are structurally composed of β-(1 → 4)-linked mannose units, which are widely distributed in plant cell walls, yeast, and bacterial exopolysaccharides. Mannans have emerged as multipurpose biopolymers with significant industrial and biomedical potential. Celebrated mannans include guar gum, locust bean gum, konjac glucomannan, yeast mannans, and softwood glucomannans. This comprehensive review highlights the sources, structural diversity, extraction methods, physicochemical properties, safety, and functional characteristics. The major bioactivities of mannans, including immunomodulatory, antioxidative, and prebiotic effects, reflect their relevance in biopharmaceutical applications. Moreover, mannans serve as valuable raw materials for developing biodegradable films, hydrogels, and nanocomposites applied in sustainable materials and drug delivery systems. Despite promising applications, challenges related to their large-scale production, standardization, and functional optimization remain to be investigated. Future perspectives focus on integrating advanced biotechnological approaches and chemical modifications to enhance the functional versatility of mannans. Overall, mannans represent a sustainable, multifunctional biopolymer with expanding applications across food, pharmaceutical, and biomedical industries.

This work deals with the preparation and identification of new azo ligand as A derivative of 2- Naphthol and It's Complexes with Co(II),Ni(II),Cu(II) and Ag(I) ions. The characterization of this ligand was done 1H-NMR,13C-NMR,Uv-Vis and FTIR spectra .The complexes preparation were performed after fixing the optimum conditions of pH and molar concentration using Uv-Vis spectra of mixed solutions of the above ions with azo ligand .A wide range of pH and molar concentration obeyed lambert-Beers Law were studies , and the stability constant has been founded at optimum conditions of pH ,mole ratio for all complex. Spectrophotometric studies such as IR and Uv-Vis and the molar conductivity of these complexes were used to determine the molecular formulas of the ligand and complexes.

Diabetes is a complex metabolic disruption affecting the glucose level of the human body. Intracellular hyperglycemia promotes mitochondrial reactive oxygen species (ROS) production, ROS directly improve the expression of inflammatory, these inflammations are associated with the level of soluble receptors for advanced glycation end-products (sRAGE) in serum. in this work assessed the level of (sRAGE) and study its potential as a biomarker for diabetes mellitus. The research included 108 Iraqis between the ages of (35-65) years of both sexes. The individuals were divided into two groups, (63) with type 2 diabetes mellitus (T2DM) and (45) control group, most of the tests serum have been measurements by colourimetric methods, and sRAGE levels in serum were evaluated by ELISA Technique. The results of the investigation showed that the sRAGE mean was more elevated compared to the mean of the control group (p < 0.00001). Statistical study of Pearson's correlation illustrated that the sRAGE level is high positively with FBG, and HBA1C (r = 0.878, p < 0.00001), (r = 0.422, P=0.05) respectively. While, negatively correlation with insulin level (r = -0.204, p = 0.010). Furthermore, most the sRAGE level denoted a positive significant correlation with kidney function parameters inclusive urea, creatinine, and ACR, except eGFR was a negative significant (r = 0.422, p = 0.05), (r = 0.501, p = 0.01), (r = 0.435, p = 0.030), (r = -0.539, p = 0.011) respectively. These results support a strong relationship between serum sRAGE level and indicators of hyperglycemia, so we can conclude that it is a great biomarker for predicting of diabetes mellitus.
