Background: Cancer, a disorder of cellular behavior is characterized by the alteration of serum glycoproteins, which are composed of different monosaccharides. One of the monosaccharides is l-fucose, a methyl pentose, which is the terminal sugar in most of the plasma glycoproteins. Elevated levels of protein-bound fucose have been reported in various disease states as well as in malignancies.
Aim: To ascertain the role of serum fucose as a biomarker and to correlate with other studies for its effective clinical application.
Materials And Method: T0 he study was carried out on 67 subjects, including 14 healthy individuals and 53 oral squamous cell carcinoma cases. The serum fucose level estimation was done based on the method as adopted by Winzler using cysteine reagent. Statistical analysis included Chi-square test, Karl Pearson correlation test and Student's t test to evaluate the significance and variability of values between groups.
Results: Serum fucose levels were independent of age and sex. However, there was significant increase in mean serum fucose level of oral squamous cell carcinoma patients compared with healthy controls. The results correlated well with other studies.
Conclusion: Serum fucose can be used as an effective diagnostic biomarker in oral squamous cell carcinoma patients.

Psoriatic arthritis (PsA) and rheumatoid arthritis (RA) are connective tissue autoimmune diseases. The present study aimed to check whether serum clusterin (CLU) concentration and its glycosylation pattern may be markers differentiating these diseases-blood sera of patients with PsA (n = 37), RA (n = 34), and healthy subjects (control, n = 21) were examined. CLU concentration was measured using the ELISA test.

Background: This study investigates the protective effects and potential mechanisms of 1,25-(OH)D against high-altitude pulmonary edema (HAPE).
Methods: Hypoxia-induced rats were administered 1,25-(OH)D for 24, 48, and 72 hours, and we observed lung tissue injury and pulmonary edema. Immunohistochemistry (IHC) and Western blot analyses were employed to analyze the expression of markers associated with ferroptosis and ferritinophagy in rat lungs.
Quantitative Assessment of Core Fucosylation for Congenital Disorders of Glycosylation.

Congenital disorders of glycosylation (CDG) include a group of diseases characterized by defects of N-glycan fucosylation. The analytical molecule of choice for the diagnosis of CDG affecting N-glycosylation is serum transferrin: approximately 10% of the glycans attached to transferrin are fucosylated via an α1,6 linkage at the innermost -acetylglucosamine residue, termed "core fucosylation." Isoelectric focusing (IEF) of transferrin is often used for diagnosis, but IEF is ineffective in detecting abnormal fucosylation.

This study investigated the molecular mechanisms of the interactions between three antitumor active monosaccharides and human serum albumin (HSA) using spectroscopic and electrochemical analyses, supplemented by molecular docking simulations. The antitumor efficacy of these monosaccharides can be significantly enhanced by covalent drug coupling, while HSA, with its long half-life and low immunogenicity, provides new opportunities for the development of advanced antitumor drug delivery systems. The results showed that these monosaccharides effectively burst the fluorescence of HSA.

Hyperuricemia and its complications caused by purine metabolism disorder continue to occur, which require effective drug treatment with fewer side effects. This study explored the positive effects of a natural homogeneous polysaccharide (AT-W) from the mycelium of Armillariella tabescens in a mouse hyperuricemia model. Structural characterization showed that the average molecular weight of AT-W is 25.
