Purpose: The effect of soy products on prostate cancer (PCA) remains a topic of debate. This study aimed to investigate the association between soy products consumption and the incidence of PCA. Materials and Methods: A search was conducted in the PubMed, EBSCO, Web of Science, and Cochrane Library databases up to December 2023. The adjusted odds ratio (OR) and corresponding 95% confidence interval (CI) were used to assess the association. Results: A total of 22 articles, comprising 1,409,213 participants, were included for this meta-analysis. The results indicate that soy products reduce the risk of PCA (OR=0.94, 95% CI=0.91–0.97, p<0.001), especially in cases of localized or low-grade PCA (OR=0.94, 95% CI=0.90–0.97, p<0.001), but exhibit no effect on non-localized or high-grade PCA (OR=0.96, 95% CI=0.91–1.01, p=0.085). Furthermore, increased consumption frequency was negatively associated with PCA risk. Specifically, soy products can reduce the risk of PCA in African Americans (OR=0.89, p=0.006) and Latinos (OR=0.93, p=0.036), but have no impact on Japanese (OR=0.99, p=0.655), Chinese (OR=0.90, p=0.155), and Whites (OR=0.96, p=0.133). Non-fermented soy products were associated with a reduction in the incidence rate of PCA (OR=0.93, 95% CI=0.90–0.96, p<0.001), while fermented soy products had no effect on the incidence rate of PCA (OR=1.10, 95% CI=0.98–1.22, p=0.096). Conclusions: The consumption of soy products can reduce the overall risk of PCA among men. Various factors, including soy products-related factors (e.g., consumption, frequency), population-related factors (e.g., race), and PCA-related factors (e.g., PCA stage) collectively influence the effect of soy products on PCA.

The hindgut of horses is an anaerobic fermentative chamber for a complex and dynamic microbial population, which plays a critical role in health and energy requirements. Research on the gut microbiota of Mongolian horses has not been reported until now as far as we know. Mongolian horse is a major local breed in China. We performed high-throughput sequencing of the 16S rRNA genes V4 hypervariable regions from gut fecal material to characterize the gut microbiota of Mongolian horses and compare them to the microbiota in Thoroughbred horses. Fourteen Mongolian and 19 Thoroughbred horses were used in the study. A total of 593,678 sequence reads were obtained from 33 samples analyzed, which were found to belong to 16 phyla and 75 genera. The bacterial community compositions were similar for the two breeds. Firmicutes (56% in Mongolian horses and 53% in Thoroughbred horses) and Bacteroidetes (33% and 32% respectively) were the most abundant and predominant phyla followed by Spirochaete, Verrucomicrobia, Proteobacteria, and Fibrobacteres. Of these 16 phyla, five (Synergistetes, Planctomycetes, Proteobacteria, TM7, and Chloroflexi) were significantly different (p<0.05) between the two breeds. At the genus level, Treponema was the most abundant genus (43% in Mongolian horses vs 29% in Thoroughbred horses), followed by Ruminococcus, Roseburia, Pseudobutyrivibrio, and Anaeroplasma, which were detected in higher distribution proportion in Mongolian horses than in Thoroughbred horses. In contrast, Oscillibacter, Fibrobacter, Methanocorpusculum, and Succinivibrio levels were lower in Mongolian horses. Among 75 genera, 30 genera were significantly different (p<0.05) between the two breeds. We found that the environment was one of very important factors that influenced horse gut microbiota. These findings provide novel information about the gut microbiota of Mongolian horses and a foundation for future investigations of gut bacterial factors that may influence the development and progression of gastrointestinal disease in horses.

A New Information Sharing Mechanism Based On Distributed Information Storage Model
Xiaoxuan Ma,Yiping Huang,Junyan Yi 보안공학연구지원센터 2015 International Journal of Database Theory and Appli Vol.8 No.5
In WWW, due to the distribution of information resources, how to manage and maintain distributed information resources in different nodes is one of the most important problems in the current research. On the basis of analyzing the scalability, efficiency and effectiveness of data exchange, the paper designed a distributed storage model, discussed the organization of the registry information, put forward a dynamically register and update mechanism, designed a distributed information search algorithm. Experimental results show that the biased flooding search algorithm based on index can not only reduce the message load but also can improve the search hit rate.

A Coupled Recursive Total Least Squares-Based Online Parameter Estimation for PMSM
Wang, Yangding,Xu, Shen,Huang, Hai,Guo, Yiping,Jin, Hai The Korean Institute of Electrical Engineers 2018 Journal of Electrical Engineering & Technology Vol.13 No.6
A coupled recursive total least squares (CRTLS) algorithm is proposed for parameter estimation of permanent magnet synchronous machines (PMSMs). TLS considers the errors of both input variables and output ones, and thus achieves more accurate estimates than standard least squares method does. The proposed algorithm consists of two recursive total least squares (RTLS) algorithms for the d-axis subsystem and q-axis subsystem respectively. The incremental singular value decomposition (SVD) for the RTLS obtained by an approximate calculation with less computation. The performance of the CRTLS is demonstrated by simulation and experimental results.

Porcine pleuropneumonia is an infectious disease caused by Actinobacillus pleuropneumoniae. The identification of A. pleuropneumoniae genes, specially expressed in vivo, is a useful tool to reveal the mechanism of infection. IVIAT was used in this work to identify antigens expressed in vivo during A. pleuropneumoniae infection, using sera from individuals with chronic porcine pleuropneumonia. Sequencing of DNA inserts from positive clones showed 11 open reading frames with high homology to A. pleuropneumoniae genes. Based on sequence analysis, proteins encoded by these genes were involved in metabolism, replication, transcription regulation, and signal transduction. Moreover, three function-unknown proteins were also indentified in this work. Expression analysis using quantitative real-time PCR showed that most of the genes tested were up-regulated in vivo relative to their expression levels in vitro. IVI (in vivoinduced) genes that were amplified by PCR in different A. pleuropneumoniae strains showed that these genes could be detected in almost all of the strains. It is demonstrated that the identified IVI antigen may have important roles in the infection of A. pleuropneumoniae.

Cationic waterborne polyurethane fluorescent material based on 4-p-N,N-bis(2-hydroxyethyl)benzyl-3,3:6,2-terpyridine (TPPDA-CWPU) was synthesized. The structure was characterized by FTIR and UV-vis spectroscopy. The content of TPPDA in the fluorescent polyurethane was 6.3×10<SUP>-4</SUP> mg/mg and the grafting ratio was 33.87%. The number-averaged and weight-average molecular weights of TPPDA-CWPU were about 16060 and 27131 g·mol<SUP>-1</SUP>, respectively. The maximum absorption wavelength of TPPDA-CWPU was blue shifted ca. 6 nm compared to TPPDA. TPPDACWPU showed different fluorescence properties under different solid content. Compared with 20% solid content, the fluorescence intensity of 1% solid content increased by ten times. The quantum yield of TPPDA-CWPU was 0.3, which was four times higher than that of TPPDA. Moreover, TPPDA-CWPU was sensitive to acidic condition and there was the phenomenon of fluorescence quenching in the case of strong acidic conditions. It is believed that more applications will be possible in the pH-responsive polymer.
