Preparation, stability, and in vitro transport of soybean protein-based diosgenin nanoemulsions.

Soybean protein isolate (SPI)-stabilized nanoemulsions (NEs) were formulated to encapsulate diosgenin (DIO) to enhance its water solubility and bioavailability. The influence of DIO concentrations on NEs' properties was investigated, and their environmental stability and cell permeability were also assessed. Results demonstrated that DIO significantly affected all the physicochemical properties of NEs.

Food-Derived High Arginine Peptides Promote Spermatogenesis Recovery in Busulfan Treated Mice.

Food-derived peptides with high arginine content have important applications in medicine and food industries, but their potential application in the treatment of oligoasthenospermia remains elusive. Here, we report that high-arginine peptides, such as Oyster peptides and Perilla purple peptides were able to promote spermatogenesis recovery in busulfan-treated mice. We found that both Opp and Ppp could increase sperm concentration and motility after busulfan-induced testicular damage in mice.

Effects of Different Dietary Flavonoids on Dipeptidyl Peptidase-IV Activity and Expression: Insights into Structure-Activity Relationship.

The inhibitory effects of 30 dietary flavonoids on dipeptidyl peptidase-IV (DPP-IV) were investigated to illustrate their quantitative structure-activity relationship (QSAR) and further explore their inhibition at the cellular level. Results of experiment show that isorhamnetin-3--glucoside (IC, 6.53 ± 0.

Antitumor effect and molecular mechanism of antioxidant polysaccharides from Salvia miltiorrhiza Bunge in human colorectal carcinoma LoVo cells.

Salvia miltiorrhiza Bunge polysaccharides (SMP) was comprehensively investigated in this study. The polysaccharides were extracted by the method of water boiling and ethanol precipitation with high purity. The monosaccharide composition of SMP was characterized using the established HPLC-UV protocol with PMP precolumn derivatization, and the results indicate that the polysaccharides are mainly composed of d-galactose (Gal), d-glucose (Glc) and d-galacturonic acid (GalUA), and their mole percentages are 64.

Stachyose increases absorption and hepatoprotective effect of tea polyphenols in high fructose-fed mice.

Scope: The consumption of tea polyphenols (TP) and stachyose contributes to preventive effects on hepatic injury. This study examined the effects of stachyose on absorption and hepatoprotective effects of TP in mice.

Methods And Results: GC-MS measurement showed that stachyose significantly increased serum total phenolic, ECG and EGCG contents in mice.

Relationship between onset of peptic ulcer and meteorological factors.

Aim: To discuss the relationship between onset of peptic ulcer (PU) and meteorological factors (MFs).

Methods: A total of 24,252 patients were found with active PU in 104,121 samples of gastroscopic examination from 17 hospitals in Nanning from 1992 to 1997. The detectable rate of PU (DRPU) was calculated every month, every ten days and every five days.

Study of the relationship between the onset of peptic ulcers and meteorological factors.

Objective: To discuss the relationship between the onset of peptic ulcers (PU) and meteorological factors (MF).

Methods: In reviewing records from 17 hospitals in the city of Nanning from 1992 to 1997, we found 24, 252 cases of PU in 104, 121 samples of gastroscopic examinations. We then calculated the detectable rate of PU (DRPU) during each season every five days (FD) and made a correlated analysis with the seasonal MF during the same period in Nanning.
