Reducing newborn mortality by 2030 is a Sustainable Development Goals target 3.2. Neonatal sepsis is the third major cause of neonatal death after prematurity and birth asphyxia. Late-onset neonatal sepsis (LOS) refers to sepsis in neonates bet and is likely to be acquired from the environment rather than mate features are not evident in the initial stages of infection, early di Studies have shown that physiological parameters can predict L features. Clinicians can use these parameters as early warning sig and intervene earlier to prevent complications and provide e compares various machine learning algorithms to predict the ons signs, laboratory measurements, and observations captured within MIMIC III dataset. Experimental results show that adaptive boost random forest with Synthetic Minority Oversampling Technique receiver operating characteristic (AUROC) of 0.9248, 0.9245, and 0.9238, respectively, among all the algorithms evaluated using 10-fold stratified cross-validation. The soft voting classifier trained on an ensemble of the top three models predicted the onset of neonatal sepsis with an AUROC of 0.9266, accuracy of 0.8553, F1 score of 0.7829, and Matthew's correlation coefficient

Antioxidant Activity and Bioavailability of Humic Substances of Low-Mineralized Sulphide Mud 低矿化硫化物泥浆腐殖质抗氧化活性及生物利用度研究
Q1 Mathematics Pub Date : 2023-01-01 DOI: 10.30919/es941
Kairbekov Zh.K., Suimbaeva S.M., Dzheldybaeva I.M., Esenalieva M.Z., Kairbekov A.Zh., Abil'mazhinova D.Z
Humic substances (HS) are natural compounds, the formation of which occurs in natural environments as a result of chemical and biological decomposition. HS make up from 60% to 80% of the organic matter of soil and aquatic environments. Therefore, we obtained samples of HS isolated from low-mineralized sulphide mud deposits of Tuzkol Lake (Republic of Kazakhstan) were obtained. HS samples have been characterized by instrumental methods: EPR spectroscopy and amperometry. Analysis of the concentration of paramagnetic centers shows that the minimum number of free radicals contains molecules of fulvic acids, and the maximum number of free radicals contains molecules of humic acids (HA) of peloids. The antioxidant activity and bioavailability of humic preparations in the form of sodium humates depending on the concentration of HS have been investigated. The information obtained indicates that HS have antioxidant activity and bioavailability, the value of which increases when the concentration of the solution grows. Dialysis of silver humate has been carried out in the presence of dimethyl sulfoxide (DMSO) at concentrations of 0.1; 1.0; 5.0 and 10% w/w. For HA and silver humate, a 10% concentration of DMSO is optimal, which allows a maximum yield of peloid preparations and a 1.6-fold increase in permeability. Dialysis of silver humate is 1.2 times more intensive than dialysis of HA. It has been shown that the change in the total content of antioxidants in various fractions of humic substances increases in the series
腐殖质(HS)是一种天然化合物,是在自然环境中经过化学和生物分解而形成的。HS占土壤和水生环境有机质的60% ~ 80%。因此,我们获得了从图兹科尔湖(哈萨克斯坦共和国)低矿化硫化物泥矿床分离的HS样品。用EPR光谱法和安培法对HS样品进行了表征。顺磁中心浓度分析表明,自由基的最小数量含有黄腐酸分子,自由基的最大数量含有类球茎的腐植酸分子。研究了腐植酸钠形式的腐植酸制剂的抗氧化活性和生物利用度随HS浓度的变化。结果表明,HS具有抗氧化活性和生物利用度,且随溶液浓度的增加而增加。在浓度为0.1的二甲亚砜(DMSO)存在下,对腐植酸银进行了透析;1.0;5.0和10% w/w。对于透明质酸和腐植酸银,10%的DMSO浓度是最佳的,这可以使球状体制剂的产量最大化,渗透率增加1.6倍。腐植酸银透析强度是透明质酸透析强度的1.2倍。结果表明,腐殖质各组分中抗氧化剂总含量的变化随系列的增加而增加
