Functional peptides are short amino acid fragments that have a wide range of beneficial functions for living organisms. The majority of previous research focused on mono-functional peptides, but a growing number of multi-functional peptides have been discovered. Although there have been enormous experimental efforts to assay multi-functional peptides, only a small fraction of millions of known peptides have been explored.

We conducted this study in China to investigate the maternal and neonatal safety of inactivated COVID-19 vaccination administered during the peri-pregnancy period.
Methods: This prospective observational cohort study enrolled pregnant women who received pregnancy care between January 1, 2021, and December 31, 2021.

In this paper, a new type of large-cavity two-anvil ultra-high pressure die structure is proposed to solve the problem that the large-scale of the two-anvil ultra-high pressure die is limited by the difficulty in machining the large-size tungsten carbide. The die is mainly composed of an internal split cylinder with an inner cone and its support ring and the external steel wire winding layer. The stress distribution and cavity dimensional stability of the split cylinder are studied by using the finite element method and compared with those of the integral cylinder.

BLA-related adverse reactions occur frequently, but whether the underlying mechanism is related to its metabolic interplay with drug-metabolizing enzymes remains unclear. This study aimed to elucidate the metabolic characteristics of BLA and its affinity action and mechanism to drug-metabolizing enzymes to reveal whether BLA-related adverse reactions are modulated by enzymes.

Methods: One hundred and two cases of Bell's palsy were randomized into an EA combined with herbal acupoint sticking group (group A, 50 cases) and an EA group (group B, 52 cases), EA at Cuanzhu (BL 2), Yangbai (GB 14), Taiyang (EX-HN 5), Quanliao (SI 18),Xiaguan (ST 7), Yingxiang (LI 20), etc. were applied in both groups and "facial paralys No.
Sulfation and glucuronidation are the principal metabolic pathways of flavonoids, and extensive phase II metabolism is the main reason for their poor bioavailabilities. The purpose of this study was to compare the similarities and differences in the positional preference of glucuronidation versus sulfation in the mouse liver S9 fraction. The conjugating rates of seven monohydroxyflavones (HFs) (i.

Seven structurally similar mono- and di-hydroxyflavones were chosen as model compounds. Human liver, C57 mouse liver and intestinal S9 fraction, as well as C57 intestinal perfusion model were used.

Objective: To determine the concentration of ginsenoside Rb(2) and study the absorption characteristics of ginsenoside Rb(2) in Caco-2 cell monolayer.
Methods: LC-MS-MS was used to determine the concentration of ginsenoside Rb(2), and the apparent permeability coefficient (P(app)) of ginsenoside Rb(2) was calculated.
Results: P(app(AP-BL)) was 3.
