Constipation is a common intestinal disease.Kiwi berries can effectively prevent constipation.However,studies have yet to be done to determine how kiwi berries prevent constipation.For two weeks,mice in this study were continually orally gavaged with kiwi berry,loperamide,or a combination of the 2.This study found that the kiwi group's feces had more water than the constipated mice.In addition,kiwi berries can speed up gastrointestinal transit(GI),shorten the time it takes to pass the first dark stool,and dramatically enhance body weight gain.In the interstitial cells of Caj al(ICC)cells and colon tissues,alterations in the protein expression of vasoactive intestinal peptide(VIP),cyclic adenosine monophosphate(cAMP),protein kinase A(PKA),and aquapcrin-3(AQP3)were found.At 3,6,and 12 h of ICC cells and mouse colon,the kiwi group's VIP,cAMP,PKA,and AQP3 protein expression levels were lower than those of the constipated mice.The kiwi berry can decrease the Firmicutes to Bacteroidetes ratio and boost the diversity and quantity of gut microbiota.By influencing the gut microbiota and VIP-cAMP-PKA-AQP3 signaling pathway,kiwi berries prevent constipation. 展开更多

Electrocatalytic CO_(2) reduction reaction(CO_(2)RR)technology,which enables carbon capture storage and resource utilization by reducing CO_(2) to valuable chemicals or fuels,has become a global research hotspot in recent decades.Among the many products of CO_(2)RR(carbon monoxide,acids,aldehydes and alcohols,olefins,etc.),alcohols(methanol,ethanol,propanol,etc.)have a higher market value and energy density,but it is also more difficult to produce.Copper is known to be effective in catalyzing CO_(2) to high valueadded alcohols,but with poor selectivity.The progress of Cu-based catalysts for the selective generation of alcohols,including copper oxides,bimetals,single atoms and composites is reviewed.Meanwhile,to improve Cu-based catalyst activity and modulate product selectivity,the modulation strategies are straighten out,including morphological regulation,crystalline surface,oxidation state,as well as elemental doping and defect engineering.Based on the research progress of electrocatalytic CO_(2) reduction for alcohol production on Cu-based materials,the reaction pathways and the key intermediates of the electrocatalytic CO_(2)RR to methanol,ethanol and propanol are summarized.Finally,the problems of traditional electrocatalytic CO_(2)RR are introduced,and the future applications of machine learning and theoretical calculations are prospected.An in-depth discussion and a comprehensive review of the reaction mechanism,catalyst types and regulation strategies were carried out with a view to promoting the development of electrocatalytic CO_(2)RR to alcohols. 展开更多

Abundant polyphenols make chokeberry have beneficial antioxidant and antiproliferative activity. In order to explore the contribution of different polyphenols in chokeberry to these activities, this study was conducted to determine polyphenol composition from 7 chokeberry varieties produced in China. Totally, 11 kinds of main polyphenol monomers were identified and quantified by UPLC-Q-TOF-MS and UPLC-PDA. HepG2 cells were used to evaluate their cellular antioxidant and antiproliferative activities. Partial least squares method was utilized to analyze multivariate correlations between proportion of different composition and monomers in total polyphenols with these activities. The results showed that the highest proportion in chokeberry polyphenols was proanthocyanidins. In comparing the bioactivities of 7 varieties of chokeberry, ‘Viking' and purple chokeberry had the strongest antioxidant activity, while 'Fukangyuan 1#' had the strongest antiproliferative activity. In terms of the contribution sources of these bioactivities, the total antioxidant activity of chokeberry mainly depended on the contribution of free polyphenols. As the main source of cellular antioxidant activity, anthocyanins and neochlorogenic acid can provide more contribution. The antiproliferative activity mainly depended on the proportion of free polyphenols and proanthocyanidins in total polyphenols. The results may provide some new possibilities for the comprehensive utilization of polyphenols from chokeberry. 展开更多

This research aimed to study the preventive and relieving outcomes of kiwi berry on constipation.The administration of kiwi berries to mice resulted in a significant increase in body weight gain of 148.2%compared to mice that were constipated.The number of stools and the water content of stools both increased by 138.5%and 106.5%,respectively.The gastrointestinal transit rate increased by 45.3%,and the time it took for the first dark stool to form decreased by 57.5%.The levels of the excitability neurotransmitters were found to be higher in the group that had been given kiwi berries in comparison to the group that had been given loperamide.The opposite results were produced by vasoactive intestinal peptide(VIP)and aquaporin-3(AQP3).In addition,kiwi berry consumption may lessen epithelial cell apoptosis and promote colon health.All the results point to kiwi berries as an extremely promising food supplement for the prevention and relief of constipation in the future since they successfully prevent and alleviate constipation brought on by loperamide. 展开更多
