Radiomics in esophagogastric junction cancer: A scoping review of current status and advances.

PURPOSE: This scoping review aimed to understand the advances in radiomics in esophagogastric junction (EGJ) cancer and assess the current status of radiomics in EGJ cancer. METHODS: We conducted systematic searches of PubMed, Embase, and Web of Science databases from January 18, 2012, to January 15, 2023, to identify radiomics articles related to EGJ cancer. Two researchers independently screened the literature, extracted data, and assessed the quality of the studies using the Radiomics Quality Score (RQS) and the METhodological RadiomICs Score (METRICS) tool, respectively. RESULTS: A total of 120 articles were retrieved from the three databases, and after screening, only six papers met the inclusion criteria. These studies investigated the role of radiomics in differentiating adenocarcinoma from squamous carcinoma, diagnosing T-stage, evaluating HER2 overexpression, predicting response to neoadjuvant therapy, and prognosis in EGJ cancer. The median score percentage of RQS was 34.7% (range from 22.2% to 38.9%). The median score percentage of METRICS was 71.2% (range from 58.2% to 84.9%). CONCLUSION: Although there is a considerable difference between the RQS and METRICS scores of the included literature, we believe that the research value of radiomics in EGJ cancer has been revealed. In the future, while actively exploring more diagnostic, prognostic, and biological correlation studies in EGJ cancer, greater emphasis should be placed on the standardization and clinical application of radiomics.

Dual-energy CT Portal Venography: Clinical Application Values and Future Opportunities.

Standard multidetector computed tomography (MDCT) uses a single X-ray tube to emit a mixed energy X-ray beam, which is received by a single detector. The difference is that dual-energy CT (DECT), a new equipment in recent years, employs a single X-ray tube or two X-ray tubes to emit two single-energy X-ray beams, which are received by a single or two detectors. The application of dual-energy technology to portal venography has become one of the research hotspots. This paper will elaborate on the clinical application values of DECT portal venography in improving portal vein image quality, distinguishing the nature of portal vein thrombus, reducing contrast agent dose and radiation dose, and will discuss the possibility of its movement from research to routine practice and future development opportunities.

Complete mitogenome for the ber fruit fly, Carpomya vesuviana (Diptera: Tephritidae) from Toksun, Northwest China and its phylogenetic relationship within family Tephritidae.

Carpomya vesuviana (Diptera: Tephritidae), commonly known as the ber fruit fly, is the most destructive insect pest of 'ber' (jujube) throughout Asia and Western Europe. Complete sequence of the mitogenome of C. vesuviana has been determined in this study. The circular genome is 15,267 bp long and contains a standard gene complement, that is, the large and small ribosomal RNA subunits, 22 transfer RNA genes, 13 genes encoding mitochondrial proteins, and a non-coding A + T-rich control region. The phylogeny showed that C. vesuviana of subfamily Trypetinae was monophyletic and clearly separated from both Dacinae and Tephritinae with maximum support (p = 1).

Complete mitochondrial genome of the bamboo-shoot fruit fly, Acrotaeniostola dissimilis (Diptera: Tephritidae) and its phylogenetic relationship within family Tephritidae.

Acrotaeniostola dissimilis (Diptera: Tephritidae) is an insect pest of bamboo shoot and distributed in the Yunnan and Sichuan Provinces, Southwest China. Complete mitogenome sequence has been determined in this study. The circular genome is 15384 bp long and contains a standard gene complement, that is, the large and small ribosomal RNA subunits, 22 transfer RNA genes, 13 genes encoding mitochondrial proteins, and a non-coding A + T-rich control region. The phylogeny showed that A. dissimilis in tribe Gastrozonini was a monophyletic branch and clearly separated from both tribe Dacini and tribe Ceratitidini with high bootstrap value supported.

Complete mitochondrial genome of white-striped long-horned beetle, Batocera lineolata (Coleoptera: Cerambycidae) by next-generation sequencing and its phylogenetic relationship within superfamily Chrysomeloidea.

White-striped long-horned beetle, Batocera lineolata occurred in China, Vietnam, Myanmar, India, Japan and Korea and is one of the most important wood-boring forestry pests. Complete mitochondrial genome was determined based on next-generation sequencing. The long-horned beetle has a total length of 15,420 bp, consisting of 13 protein-coding genes (PCGs), 22 tRNA, 2 rRNA genes and a non-coding region. The phylogenetic position was closely clustered with 6 other Lamiinae species with strong node support. Within Chrysomeloidea superfamily, a monophyletic Lamiinae clad is recovered as the sister group of the Cerambycinae from three species and the Chrysomelidae consisting five species forms a monophyletic clade which is strongly supported.

Characterization of mitochondrial genome and phylogenetic implications for Chinese black ant, Polyrhachis dives (Hymenoptera: Formicidae).

Chinese black ant, Polyrhachis dives Smith, also known as P. vicina Roger has been used as a traditional edible insect and Chinese medicine in China and some southeast countries for thousands of years. In this study, Mitogenome of this species was assembled with high coverage using Illumina sequencing data and is 15,806 bp long in size. The base composition is 37.8% for A, 12.5% for C, 6.4% for G and 43.3% for T. The mitogenome contains 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. The phylogeny showed that it was closely related to Camponotus atrox (Hymenoptera: Formicidae) with high bootstrap value supported. The mitogenome of P. dives can provide essential DNA molecular data for further phylogenetic and evolutionary analysis.

Complete mitochondrial genome of stripped fruit fly, Bactrocera (Zeugodacus) scutellata (Diptera: Tephritidae) from Anshun, Southwest China.

The striped fruit fly, Bactrocera (Zeugodacus) scutellata occurred in East and Southeast Asia and is one of the most serious pest insects in China. Complete mitochondrial genome was sequenced and characterized for the fruit fly from Anshun, Guizhou Province in Southwest China. The pest fruit fly has a total length of 15,904 bp, consisting of 13 protein-coding genes (PCGs), 22 tRNA, 2 rRNA genes and a non-coding region (A + T-rich control region). The phylogenetic position of B. scutellata was closely clustered with B. cucurbitae, B. tau, B. caudata and B. diaphora. The all species of the subgenus Zeugodacus formed a sister group which was monophyletic. The complete mitochondrial genome of B. scutellata will provide helpful information for genetics, systematics and phylogeny of tephritid fruit flies, Particularly Bactrocera genus.

Complete mitochondrial genome of Simao pine caterpillar moth, Dendrolimus kikuchii (Lepidoptera: Lasiocampidae) and the related phylogenetic analysis.

Dendrolimus kikuchii, the Simao pine caterpillar moth is an economically important forest pest causing great damage to coniferous trees in south China. The whole mitogenome for the moth was sequenced using next-generation sequencing technology. The moth has a total length of 15,422 bp in mitogenome size. The nucleotide composition is biased toward adenine and thymine, accounting for 79.2%: A = 40.7%, T = 38.5%, G = 8.1%, and C = 12.7%. The phylogeny showed that D. kikuchii was closely grouped with D. punctatus, D. tabulaeformis, Euthrix laeta, and Trabala vishnou guttata to form the monophyletic clad for the Lasiocampidae family of Bombycoidea superfamily with strong nodal support.
