AAPM Truth-based CT (TrueCT) reconstruction grand challenge.

Background: This Special Report summarizes the 2022, AAPM grand challenge on Truth-based CT image reconstruction.

Purpose: To provide an objective framework for evaluating CT reconstruction methods using virtual imaging resources consisting of a library of simulated CT projection images of a population of human models with various diseases.

Methods: Two hundred unique anthropomorphic, computational models were created with varied diseases consisting of 67 emphysema, 67 lung lesions, and 66 liver lesions.

Diagnostic challenge presented by extranodal NK/T cell lymphoma expressing CD20, CD30 and CD15: A case report.

The atypical expression of immune phenotypes in lymphoma is often associated with a poor prognosis and presents diagnostic challenges. The present study reports on a rare extranodal NK/T cell lymphoma. In addition to typical morphology and immunohistochemical characteristics, these tumors strongly express CD20 and CD30 and partially express CD15, which is associated with aggressive clinical behavior.

Effectiveness of a nurse-led coaching in self-care intervention for elderly undergoing total laryngectomy: a randomised controlled trial.

Objectives: To evaluate the effectiveness of nurse-led coaching in self-care (SC) interventions for elderly patients undergoing total laryngectomy (TL) using multidimensional parameters.

Design: This was a double-arm randomised, single-centre trial that met the requirements of the CONSORT statement.

Setting: Head and neck department in a tertiary A-level hospital.

Engineering a cpGFP-based biosensor for enhanced quantification of glycolate production in Escherichia coli.

The growing demand for glycolate, fueled by economic development, requires the advancement of production methods. Escherichia coli (E. coli), a preferred host for glycolate production, has undergone extensive metabolic engineering to improve yield.

Assembly of soil multitrophic community regulates multifunctionality via multifaceted biotic factors in subtropical ecosystems.

Soil biodiversity underpins multiple ecosystem functions and services essential for human well-being. Understanding the determinants of biodiversity-ecosystem function relationships (BEFr) is critical for the conservation and management of soil ecosystems. Community assembly processes determine community diversity and structure.
