Sialylation, a crucial yet labile protein modification, is increasingly recognized for its role in modulating structure, function, and stability. While the impact of oxidative stress on integrity well-established, protective sialylation against such damage remains poorly understood. This study employs microscale low-temperature plasma device to generate controlled, deep radical oxidation environment mimicking cellular stress. By subjecting free sialic acids (Neu5Ac Neu5Gc) time-resolved exposure, high-resolution mass spectrometry, high-fidelity density functional theory calculations, we establish an unprecedented pathway, revealing unique stepwise side chain prior ring opening. Comprehensive maps comprising over 100 intermediates provide molecular basis higher propensity Neu5Gc Neu5Ac resisting oxidation. Further, using human transferrin as model glycoprotein, demonstrate unfolding. Through combination site mapping, enzymatic treatments, all-ion unfolding ion mobility-mass identify specific patterns structural motifs that are maintaining stability under Our findings insights into intricate interplay between stress, highlighting importance stabilizing conformations various stresses.

The aim of this study was to investigate the relationship between red blood cell distribution width and albumin ratio (RAR) levels mortality in adult patients with sarcopenic obesity United States. included 1,361 from National Health Nutrition Examination Survey (1999–2006). X-tile used determine optimal subgroup thresholds for RAR values, propensity score matching (PSM) employed reduce baseline bias. Cox regression analysis, Kaplan-Meier survival curves, restricted cubic spline analysis were utilized assess all-cause cardiovascular mortality. Subgroup Subpopulation Treatment Effect Pattern Plot advantages across different subgroups. Time-dependent ROC evaluate accuracy level predicting outcomes at time points. Post-PSM multifactorial analyses revealed that a significant independent predictor (HR 1.487, 95% CI: 1.259–1.756) an risk factor 1.260–1.758) obesity. advantage consistent Restricted indicated approximate S-shaped association curves demonstrate areas under 1-year, 3-year, 5-year, 10-year are 0.79, 0.66, 0.64, 0.63, respectively. curve 0.80, 0.70, 0.61, Moreover, comparison model lacking covariates, AUC values joint exhibited heightened various Therefore, We demonstrated is prognostic American population obesity, it reasonable consider as simple effective prediction tool.
