Inflammatory and Nutritional Status Influences Outcomes of Minimally Invasive Esophagectomy.

Introduction: The potential association between severe postoperative complications (SPC) and the oncological outcomes of esophageal squamous cell carcinoma (ESCC) patients according to the different Naples Prognostic Score (NPS) of the inflammatory nutritional status after minimally invasive esophagectomy (MIE) is unclear.

Methods: Kaplan-Meier survival analysis was used to evaluate overall survival (OS) and disease-free survival (DFS) between with or without SPC (Clavien-Dindo grade ≥ III) in low NPS status (NPS = 0 or 1) and high NPS status (NPS = 2 or 3 or 4) patients. Cox multivariable analysis was carried out to analyze the various independent factors of OS and DFS, and a nomogram based on SPC was established.

High-quality genome assembly and transcriptome of Ancherythroculter nigrocauda, an endemic Chinese cyprinid species.

Ancherythroculter nigrocauda is a cyprinid fish endemic of the upper reaches of the Yangtze River in China, where it is an important aquaculture and commercial species. It is also a threatened species as a result of overfishing, dam construction and water pollution. In this study, a chromosome-level genome assembly of A.

Successful Invasions of Short Internally Deleted Elements (SIDEs) and Its Partner CR1 in Lepidoptera Insects.

Although DNA transposons often generated internal deleted derivatives such as miniature inverted-repeat transposable elements, short internally deleted elements (SIDEs) derived from nonlong terminal-repeat retrotransposons are rare. Here, we found a novel SIDE, named Persaeus, that originated from the chicken repeat 1 (CR1) retrotransposon Zenon and it has been found widespread in Lepidoptera insects. Our findings suggested that Persaeus and the partner Zenon have experienced a transposition burst in their host genomes and the copy number of Persaeus and Zenon in assayed genomes are significantly correlated.

Unexpected invasion of miniature inverted-repeat transposable elements in viral genomes.

Background: Transposable elements (TEs) are common and often present with high copy numbers in cellular genomes. Unlike in cellular organisms, TEs were previously thought to be either rare or absent in viruses. Almost all reported TEs display only one or two copies per viral genome.

Genome-wide identification and evolution of TC1/Mariner in the silkworm (Bombyx mori) genome.

TC1/Mariner transposons belong to class II transposable elements (TEs) that use DNA-mediated "cut and paste" mechanism to transpose, and they have been identified in almost all organisms. Although silkworm (Bombyx mori) has a large amount of TC1/Mariner elements, the genome wide information of this superfamily in the silkworm is unknown. In this study, we have identified 2670 TC1/Mariner (Bmmar) elements in the silkworm genome.
