Simulated gastrointestinal digestion of walnut protein yields anti-inflammatory peptides.

The impact of the simulated gastrointestinal digestion process on walnut protein and the potential anti-inflammatory properties of its metabolites was studied. Structural changes induced by digestion, notably in α-Helix, β-Turn, and Random Coil configurations, were unveiled. Proteins over 10,000 Da significantly decreased by 35.

Serial passage of PDCoV in cell culture reduces its pathogenicity and its damage of gut microbiota homeostasis in piglets.

Porcine deltacoronavirus (PDCoV) is an enteropathogenic coronavirus that mainly causes diarrhea in suckling piglets, and also has the potential for cross-species transmission. However, there are still no commercial vaccines available to prevent and control PDCoV infection. In this study, PDCoV strain HNZK-02 was serially propagated for up to 150 passages and the amino acid changes have mainly occurred in the S protein during serial passage which caused structure change.

Antioxidant properties and changes in vitro digestion of the fermented kiwifruit extract prepared by lactic acid bacteria and yeasts.

The health benefits of fermented fruits have attracted consumers' attention. High levels of antioxidant ability in the fermented kiwifruit extract were found at the early stage of fermentation. The co-fermention with Lactobacillus paracasei LG0260 and Kluyveromyces marxianus J2853 showed the highest ABTS radical scavenging ability (ABTS-SA) and superoxide dismutase (SOD) activity.

Electroacupuncture pretreatment induces rapid tolerance to bupivacaine cardiotoxicity in rats.

Background: Evidence suggests that electroacupuncture (EA) protects against arrhythmia and myocardial injury induced by myocardial ischaemia-reperfusion. However, to our knowledge, it remains unknown whether EA could alleviate bupivacaine-induced cardiotoxicity. Therefore, we aimed to explore the effect of EA pretreatment on bupivacaine-induced cardiac arrest and outcomes of cardiopulmonary resuscitation (CPR) in rats.

[Effects of pretreatment of electroacupuncture on bupivacaine poisoning in rats].

Objective: To observe the effects of electroacupuncture (EA) pretreatment at different times for heart arrest induced by bupivacaine poisoning in rats.

Methods: With a randomized, blind, control study, 24 SD rats were divided into a control group, a EA for 60 min (EA 60) group and a EA for 30 min (EA 30) group, 8 cases in each one. Rats in the EA 60 group and EA 30 groups were treated with EA at bilateral "Neiguan" (PC 6), "Zusanli" (ST 36) and "Fenglong" (ST 40) for 60 min and 30 min respectively.

[Multiple functions of transcutaneous electrical acupoint stimulation in peri-anesthesia period].

Through literature retrieval, the effects of transcutaneous electrical acupoint stimulation (TEAS) in peri-anesthesia period are summarized. It is found out that TEAS can reduce anesthetics consumption, relieve stress reaction of surgery, stabilize patients' hemodynamics, reduce surgical complication and improve immune function and quality of recovery; besides, it has protective function on heart, brain, liver, stomach, intestines and so on. However, except certain analgesic effect, the sham TEAS and transcutaneous electrial nerve stimulation do not have other functions of TEAS.
