Accurate image reconstruction within and beyond the field-of-view of CT system from data with truncation.

Objective: Accurate image reconstruction from data with truncation in X-ray computed tomography (CT) remains a topic of research interest; and the works reported previously in the literature focus largely on reconstructing an image only within the scanning field-of-view (FOV). We develop algorithms to invert the data model with truncation for accurate image reconstruction within the entire subject support or a region slightly smaller than the subject support.

Methods: We formulate image reconstruction from data with truncation as an optimization program, which includes hybrid constraints on image total variation (TV) and image L1-norm for effectively suppressing truncation artifacts.

Rapid Determination of Crocin-I in Gardenia Fruits (Gardenia jasminoides Ellis) by Combining Spectral and Image Data Through Hyperspectral Imaging.

Introduction: Crocin-I, a water-soluble carotenoid pigment, is an important coloring constituent in gardenia fruit. It has wide application in various industries such as food, medicine, chemical industry, and so on. So the content of crocin-I plays a key role in evaluating the quality of gardenia.

Causal association between gut microbiome and polycystic ovary syndrome: A bidirectional Mendelian randomization study.

Through implementing a bidirectional Mendelian randomization (MR) study, the causal effects between gut microbiome and polycystic ovary syndrome (PCOS) were analyzed. Summary statistics for PCOS were acquired from the FinnGen consortium R8 release data, which included 27,943 cases and 162,936 controls. The inverse-variance weighting (IVW) method was adopted for analysis.

Tumor burden with AFP improves survival prediction for TACE-treated patients with HCC: An international observational study.

Background & Aims: Current prognostic models for patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) are not extensively validated and widely accepted. We aimed to develop and validate a continuous model incorporating tumor burden and biology for individual survival prediction and risk stratification.

Methods: Overall, 4,377 treatment-naive candidates for whom TACE was recommended, from 39 centers in five countries, were enrolled and divided into training, internal validation, and two external validation datasets.

Case report: Anesthesia management for surgical treatment of glucagonoma with symptom of characterized necrolytic migratory erythema.

Background: The anesthetic management of patients with glucagonoma is complicated by a number of factors including glucose fluctuation, characterized necrolytic migratory erythema in oral and pharyngeal, which may lead to an unexpected difficult airway.

Case Presentation: Herein we describe the anesthetic considerations and management of a 47-year-old adult with glucagonoma, who presented for a laparoscopic splenectomy and distal pancreatectomy procedure.

Conclusion: This report details fiberoptic intubation in an adult with glucagonoma and necrolytic migratory erythema.
