To date, no prospective study has been conducted to compare the safety and effectiveness of endoscopic snare resection with an elastic band (ESR-EB) and endoscopic snare resection with a transparent cap (ESR-C) for treating gastric muscularis propria lesions. We aimed to compare the safety and effectiveness of ESR-EB with those of ESR-C for gastric muscularis propria lesions less than 10 mm in diameter. A total of 64 patients were enrolled prospectively from May 2023 to November 2023 at Shenzhen Hospital of Southern Medical University, the First Affiliated Hospital of Shantou University, and the People's Hospital of Zhongshan City.

Through amplification of V3-V4 and ITS1-5f variable regions of 16S and internal transcribed spacer (ITS) rRNA, the study was based on the location (Kunming, Qujing, and Zhaotong), plant components (rhizosphere soil and roots), and sample types (healthy and diseased) to assess the diversity of bacterial and fungal communities. We found plant components significantly influence microbial diversity, with rhizosphere soil being more diverse than roots, and the microbial community in the root is mainly derived from the rhizosphere soil.

However, inducing sexual spore formation under in vitro conditions has been challenging, impeding further research on its control. In this study, field experiments were conducted to assess the effects of different concentrations of chemical and biological fungicides on the production of sexual spores of AG-3 TB on tobacco plants.

Virus-like symptoms of plants were observed on leaves in some plantations in Zhanyi and Wuding Counties, Yunnan Province, southwest China. High-throughput sequencing (HTS) was performed on 28 symptomatic plants, and the results revealed infection with 11 viruses, including 2 novel viruses and 9 previously described viruses: Aconitum amalgavirus 1 (AcoAV-1), aconite virus A (AcVA), cucumber mosaic virus (CMV), currant latent virus (CuLV), apple stem grooving virus (ASGV), chilli veinal mottle virus (ChiVMV), tomato spotted wilt orthotospovirus (TSWV), tobacco vein distorting virus (TVDV), and potato leafroll virus (PLRV).

This study isolated a virus designated as Rhizoctonia solani partitivirus BS-5 (RsPV-BS5) from the AG-3 strain BS-5, the causal agent of tobacco target spot disease. The virus was identified as a strain of RhsV717.

The virus has a single-stranded positive-sense RNA (+ssRNA) genome of 6141 nucleotides containing two open reading frames (ORFs) and a poly(A) tail. ORF1 encodes a large polypeptide of 1,862 amino acids (aa) with conserved RNA-dependent RNA polymerase (RdRp) and helicase (Hel) domains.

The anastomosis group-3 (AG-3) pathogen is divided into different subgroups namely AG-3 PT (potato type), AG-3TB (tobacco type), and AG-3 TM (tomato type), based on their host and the combined data from the ribosomal DNA internal transcribed spacer (rDNA-ITS), rDNA intergenic spacer 1 (rDNA-IGS1) regions, and translation elongation factor 1-α (tef-1α) gene. In this study, we collected tobacco leaves showing target spot symptom from four fields in China.

We aimed to construct a clinically applicable artificial intelligence (AI) system for the identification of presence of cancer invasion in large sessile colorectal polyps.
Methods: A deep learning-based colorectal cancer invasion calculation (CCIC) system was constructed.
The nucleotide sequence of a viral double-stranded RNA (dsRNA) from Rhizoctonia solani AG-4 HGIII strain XMC-IF (designated as "Rhizoctonia solani mitovirus 106", RsMV-106) was determined. The complete sequence was 2794 bp in length with a 57.50% A + U content and contained a large open reading frame (ORF) when the fungal mitochondrial genetic code was used.
