Highly acid-sensitive Bifidobacterium adolescentis (ATCC 15703) cells were entrapped in pea, soy, faba, and lentil protein-alginate capsules and subjected to challenge studies in synthetic gastric juice (SGJ, pH 2.5/37oC) and intestinal fluids (SIF, pH 6.5/37oC). B. adolescentis cells trapped in pea, soy, faba, and lentil protein-alginate capsules showed 1.9, 3.3, 5.1, and 5.5 log reductions in cell numbers, respectively after a 2 h challenge. Release of encapsulated B. adolescentis cells in SIF over 3 h indicated that after the first 10 min, almost all cells were released, regardless of the wall material. Storage of pea protein-based capsules was also tested in commercial orange, pineapple, and white grape juices at 4 and 22℃ for a 6-week duration. Encapsulated B. adolescentis cells survived in pineapple and white grape juice, but not in orange juice.

Objective : This study aimed to investigate the changes and significance of microRNA155 levels in serum of patients with cerebral small vessel disease (CSVD). Methods : Thirty patients with CSVD who met the inclusion criteria were selected and divided into eight patients with lacunar infarction (LI) group and 22 patients with multiple lacunar infarction (MLI) combined with white matter lesions (WML) group according to the results of head magnetic resonance imaging (MRI). Thirty samples from healthy volunteers without abnormalities after head MRI examination were selected as the control group. The levels of serum microRNA155 in each group were determined by real-time polymerase chain reaction, and the correlation between microRNA155 in the serum of patients with CSVD and the increase of imaging lesions was analyzed by Spearman correlation analysis. Results : Compared with the control group, the serum microRNA155 level in the LI group, MLI combined with WML group increased, the difference was statistically significant (p<0.05); serum microRNA155 level was positively correlated with the increase of imaging lesions (p<0.05). Conclusion : The change of serum microRNA155 level in patients with CSVD may be one of its self-protection mechanisms, and the intensity of this self-protection mechanism is positively correlated with the number of CSVD lesions.
