Electroactive anticorrosion coatings are specialized surface treatments that prevent or minimize corrosion. Thestudy employs strategic thermodynamic equilibriumcalculations to pioneer a novel factor in corrosion protection.A first-time proposal, the total acidity (TA) potential of the hydrogen (pH) concept significantly shapes medicalmagnesium alloys. These coatings are meticulously designed for robust corrosion resistance, blending theoreticalinsights and practical applications to enhance our grasp of corrosion prevention mechanisms and establisha systematic approach to coating design. The groundbreaking significance of this study lies in its innovativeintegration of the TA/pH concept,which encompasses the TA/pH ratio of the chemical environment. This approachsurpasses convention by acknowledging the intricate interplay between the acidity and pH levels within thecoating formulation, thereby optimizing metal-phosphate-based conversion coatings and transforming corrosionmitigation strategies. To authenticate the TA/pH concept, the study comprehensively compares its findings withexisting research, rigorously validating the theoretical framework and reinforcing the correlates among TA/pHvalues and observed corrosion resistance in the coatings. The influence of mutations that occur naturally inthe detergent solution on persistent phosphorus changes is shown by empirical confirmation, which improvescorrosion resistance. This realization advances the field ofmaterials and the field’s knowledge of coated generation,particularly anticorrosion converter layers.

Quality and yield are the primary concerns in kiwifruit breeding,but research on the genetic mechanisms of fruit size,shape,and ascorbic acid(ASA)content is currently very limited,which restricts the development of kiwifruit molecular *** this study,we obtained a total of 8.88 million highly reliable single nucleotide polymorphism(SNP)markers from 140 individuals from the natural hybrid offspring of Actinidia eriantha cv.‘White’using whole genome resequencing technology.A genome-wide association study was conducted on eight key agronomic traits,including single fruit weight,fruit shape,ASA content,and the number of inflorescences per branch.A total of 59 genetic loci containing potential functional genes were located,and candidate genes related to single fruit weight,fruit length,ASA content,number of inflorescences per branch and other traits were identified within the candidate interval,such as AeWUSCHEL,AeCDK1(cell cycle dependent kinase),AeAO1(ascorbic oxidase)and AeCO1(CONSTANS-like 4).After constructing an RNAi vector for AeAO1 and injecting it into the fruit of cv.‘Midao 31’to interfere with the expression of the AeAO1 gene,the results showed that the activity of ascorbic oxidase in the fruit of‘Midao 31’significantly decreased,while the content of ASA significantly *** study provides valuable insights into the genetic basis of variation in *** fruit traits,which may benefit molecular marker-assisted breeding efforts.

Alzheimer's disease （AD） has become an important public health issue worldwide. P-Coumaric acid （CA） and lactoferrin （Lf） possessed antioxidant， anti-inflammatory， and anti-AD activities. Herein， we hypothesized that a combination treatment of CA and Lf would synergistically improve AD symptoms and studied its mechanisms. Twelve-week-old APP/PS1 mice were treated with CA， Lf， or both CA and Lf for 8 weeks. Results showed that individual and combined treatments could ameliorate cognitive deficits to varying degrees， with stronger effects for combined intervention than for CA or Lf alone. Specifically， combined treatment was most effective in improving nesting ability and reducing Aβ1-42deposition in mice. Moreover， combined treatment was more effective in suppressing APP， BACE1， and inflammation; it inhibited the CCAAT-enhancer-binding protein （C/EBPβ）/asparagine endopeptidase （AEP） signaling pathway in the hippocampus and colon and upregulated the expression of tight junction protein ZO-1 in the colon; it also decreased the F/B ratio at the phylum level and increased the relative abundance of Prevotellaceae， Lachnospira， and Eubacterium at the genus level. Overall， the combination of CA and Lf may ameliorate cognitive deficits in APP/PS1 mice by improving inflammation and inhibiting the C/EBPβ/AEP signaling pathway via modulating gut microbiome.
