The aim of this study was to explore the diversities in bacterial communities in the unfermented pulps (control) (PNFL) and fermented pulps obtained from fruits using boiling (PMF) and purchased at markets in Brazzaville (PFL) and using Illumina MiSeq<sup>TM</sup> sequencing of 16S rRNA gene. A total number of 157,054 sequences was obtained and grouped into 737 operational taxonomic units (OTUs). These were classified into 13 phyla, 26 classes, 48 orders, 96 families and 176 genera. At the phylum level, the most frequent bacterial communities were: for PFM, Proteobacteria (38.94%) and Firmicutes (19.37%);for PFL, Firmicutes (69.10%) and Proteobacteria (30.89%);for PNFL, Firmicutes (84.92%) and Proteobacteria (14.22%). were the most frequent in PFL, while Acidobacteria (40.02%), Proteobacteria (38.94%) and Firmicutes (19.37%) were preponderant in PFM. Firmicutes (84.92%) and Proteobacteria (14.22%) were the most common in unfermented pulps (PNFL). Lactobacillus (47.70%) and Gluconobacter genera (15.33%) were the most represented in the PFL sample. Acidipila (35.56%) and Rhizomicrobium (11.41%) were preponderant genera in the PFM sample. Weissella genus was the most frequent in the PNFL sample. Hierarchical cluster indicated that the samples could be grouped into two groups of different origins. PCA showed that main genera were higher in the fermented samples. The diversity was higher in the fermented pulps or Pandé than in the unfermented pulps. Pandé can be a potential source for the isolation of bacteria with biotechnological potential.展开更多

All through the ages many people have carved poems at the top of the Taishan Mountains. However, my favorite spot is the Heavenly Pond on top of the Changbai Mountains. The Changbai Mountains are located in Antu County in the Yanbian Korean Autonomous Prefecture of Jilin Province.展开更多

However, the rational extent lymphadenectomy for local advanced gastric cancer has remained a topic of debate in the past decades. Due to the limitation of low metastatic rate in para-aortic nodes （PAN） in JCOG9501, the clinical benefit of D2＋ para-aortic nodal dissection （PAND） for patients with stage T4 and/or stage N3 disease, which is very common in China and other countries except Japan and Korea, cannot be determined. Furthermore, the role of splenectomy for complete resection of No.10 and No.l I nodes has been controversial, and however, the final results from the randomized trial ofJCOG0110 have yet to be completed. Gastric cancer with the No.14 and No.13 lymph node metastasis is defined as MI stage in the current version of the Japanese classification. We propose that D2~No.14v and ＋No.13 lymphadenectomy may be an option in a potentially curative gastrectomy for tumors with apparent metastasis to the No.6 nodes or infiltrate to duodenum. The examined lymph node and extranodal metastasis are significantly associated with the survival of gastric cancer patients.展开更多
