1d). From the original fragmentation tree, its structure and all losses are kept, and some new internal node is selected as new root, with the molecular formula of the precursor ion. Molecular formulas of all fragment ions are calculated along the edges of the tree, subtracting losses. In ...
This result allows us to obtain a new approximation of the distribution of the local score of one sequence. This approximation improves the one given by Karlin et al., which can be deduced from this new formula. We obtain a more accurate asymptotic expression with additional terms. Examples ...
Chlorogenic acid is a light yellow solid with the molecular formula C16H18O9 . Chlorogenic acid, as a polar organic acid, is less stable and undergoes isomerization by hydrolysis and subsequent intramolecular migration of ester groups during extraction from plants. Chlorogenic acid and iso-Chlorogenic...
n-Butyllithium has a molecular formula of C4H9Li and a molecular weight of 64.05. The pure product is a white powder with extremely strong reducing properties and is resistant to water and oxidants. Very easy to generate heat and burn. The product is a solution dissolved in saturated hydrocarbo...

Kidney diseases remain one of the leading causes of human death and have placed a heavy burden on the medical system. Regulated cell death contributes to the pathology of a plethora of renal diseases. Recently, with in-depth studies into kidney diseases
The PNI value was calculated using the following formula: PNI = serum albumin (g/L) + 5*peripheral blood lymphocyte count (*109/L). The classification of BMI was based on the criteria specific for Chinese population: BMI < 18.5 kg/m2 (underweight), 18.5–23.9 kg/m2 (normal...
In the formula, Expr(i) represented the expression value of each lncRNA, and Coef(i) represented the regression coefficient of multivariate Cox regression analysis for each lncRNA. The BLCA patients were divided into high-risk and low-risk groups based on the median risk score. Kaplan-Meier ...
