This report describes a rare presentation of primary bronchial ES in a 31-year-old female who was referred to the emergency department of our hospital due to suspicion of a foreign body in the bronchus.

Identification of as the Pathogen Associated with Massive Mortality in Bronze Gudgeon ().

, an opportunistic pathogen toward aquatic organisms, was identified as the causative pathogen (isolate WH10) in diseased bronze gudgeon via bacterial isolation, and morphological, physiological, biochemical, and molecular characterization. WH10 exerted its pathogenicity via five virulence genes, including those encoding cytotoxic enterotoxins (act and alt), lipase (lip), a quorum sensing-controlled virulence factor (LuxS), and a Type III secretion system inner membrane component (ascV). WH10 was shown to be sensitive to compound sulfamethoxazoles, cefothiophene, doxycycline, and sulfamethoxazole.

A study of the thermal comfort in urban mountain parks and its physical influencing factors.

Urban thermal comforts are increasingly holding people's attention due to global warming and urban heat islands. Urban parks can absorb sunlight radiation, which reduces air temperature, improving urban microclimates. Various factors in the park are confirmed to be effective in heat mitigation.

A study of waterside microenvironmental factors and their effects on summer outdoor thermal comfort in a Cfa-climate campus.

Outdoor thermal comfort (OTC) studies explore outdoor subjects' responses to their thermal environment, usually evaluated using the neutral temperature (NT). This study investigated the influences of microenvironmental factors around a waterbody on thermal perceptions, using questionnaires and meteorological measurements at the Central Lake of Southwest University of Science and Technology (SWUST) in Mianyang. Microenvironmental factors included sky view factor (SVF) and distance from the lake (DFL).

Whole-genome DNA methylation profiling reveals epigenetic signatures in developing muscle in Tan and Hu sheep and their offspring.

Introduction: The Tan sheep is a popular local breed in China because of its tenderness and flavor. The Hu sheep breed is also famous for its high litter size, and its muscle growth rate is faster than that of Tan sheep. However, the epigenetic mechanism behind these muscle-related phenotypes is unknown.

Objective: To build T2WI-based multiregional radiomics for predicting tumor deposit (TD) and prognosis in patients with resectable rectal cancer.

Materials And Methods: A total of 208 patients with pathologically confirmed rectal cancer from two hospitals were prospectively enrolled. Intra- and peritumoral features were extracted separately from T2WI images and the least absolute shrinkage and selection operator was used to screen the most valuable radiomics features.

Indoor thermal responses and their influential factors-- impacts of local climate and contextual environment: A literature review.

Indoor thermal comfort/perception (ITC) would be affected by contextual factors. The present article reviewed findings (thermal responses represented by neutral temperature, NT) of ITC studies published in recent decades. There were two types of contextual factors: climate (latitude, altitude, and distance from the sea) and building characteristics (building type, and ventilation mode).

Analysis of mA modulator-mediated methylation modification patterns and the tumor microenvironment in lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is the most common histological subtype of lung cancer. In the development and progression of LUAD, epigenetic aberration plays a crucial role. However, the function of RNA N6-methyladenosine (mA) modifications in the LUAD progression is unknown.

Ewing sarcoma of the ileum with wide multiorgan metastases: A case report and review of literature.

Background: Ewing sarcoma (ES) is an aggressive small round cell tumor that usually occurs in younger children and young adults but rarely in older patients. Its occurrence in elderly individuals is rare. ES of the ileum with wide multiorgan metastases is rarely reported and difficult to distinguish radiologically from other gastrointestinal tract tumors.

The application of apparent diffusion coefficients derived from intratumoral and peritumoral zones for assessing pathologic prognostic factors in rectal cancer.

Objective: To investigate the diagnostic performance of the apparent diffusion coefficient (ADC) derived from intratumoral and peritumoral zones for assessing pathologic prognostic factors in rectal cancer.

Materials And Methods: One hundred forty-six patients with rectal cancer who underwent preoperative MRI were prospectively enrolled. Two radiologists independently placed free-hand regions of interest (ROIs) in the largest tumor cross section and three small ROIs on the peritumoral zone adjacent to the tumor contour.

Materials And Methods: Seventy-nine patients with biopsy-proven rectal adenocarcinoma who underwent pre- and post-CRT MRI and surgery were prospectively enrolled. The exclusion criteria included nonresectable and/or metastatic disease and loss of follow-up.

Thymocytes induce renal tubular epithelial cells to undergo the epithelial-to-mesenchymal transition.

Background: Renal tubulointerstitial fibrosis is known to occur as a result of epithelial cell transformation into myofibroblasts via the epithelial-to-mesenchymal transition (EMT) process. It has been reported that macrophages, regulatory T (Treg) cells, and gamma delta T (γδ T) cells can promote fibrosis via EMT in vivo.

Objective: Our study intended to detect whether thymocytes can induce renal tubular cells to undergo the EMT.

Outdoor Scene Understanding Based on Multi-Scale PBA Image Features and Point Cloud Features.

Outdoor scene understanding based on the results of point cloud classification plays an important role in mobile robots and autonomous vehicles equipped with a light detection and ranging (LiDAR) system. In this paper, a novel model named Panoramic Bearing Angle (PBA) images is proposed which is generated from 3D point clouds. In a PBA model, laser point clouds are projected onto the spherical surface to establish the correspondence relationship between the laser ranging point and the image pixels, and then we use the relative location relationship of the laser point in the 3D space to calculate the gray value of the corresponding pixel.

Comparative outcomes of the two types of sacral extradural spinal meningeal cysts using different operation methods: a prospective clinical study.

This prospective study compares different clinical characteristics and outcomes of patients with two types of sacral extradural spinal meningeal cysts (SESMC) undergoing different means of surgical excision. Using the relationship between the cysts and spinal nerve roots fibers (SNRF) as seen under microscope, SESMCs were divided into two types: cysts with SNRF known as Tarlov cysts and cysts without. The surgical methods were tailored to the different types of SESMCs.
