CdWO Sub-1 nm Nanowires for Visible-Light CO Photoreduction.

Quantum size effect usually causes energy level splitting and band broadening as material size decreases. However, this may change again by the surface adsorbents, doping and defects, which rarely attracts much attention. Herein, CdWO sub-1 nm nanowires (SNWs) with oleylamine adsorption, PO -doping and oxygen defects are synthesized by combining Cd(CHCOO), HPWO (PW) and oleylamine (abbreviated as PO -CdWO-X SNWs).

PET-MR Imaging and MR Texture Analysis in the Diagnosis of Pancreatic Cysts: A Prospective Preliminary Study.

Rationale And Objectives: Our aim was to evaluate the capability of textural and metabolic parameters measured at pretreatment F-fluorodeoxyglucose Positron emission tomography (PET)-MR in differentiating malignant from benign pancreatic cystic lesions.

Materials And Method: Forty consecutive patients were prospectively enrolled in this study. They underwent simultaneous PET-MR for the diagnosis of pancreatic cysts.

Unresectable pancreatic ductal adenocarcinoma: Role of CT quantitative imaging biomarkers for predicting outcomes of patients treated with chemotherapy.

Objectives: The primary aim of this study was to determine if computed tomographic (CT) texture analysis measurements of the tumor are independently associated with progression-free survival (PFS) and overall survival (OS) in patients with unresectable pancreatic ductal adenocarcinoma (PDAC), including both unresectable locally advanced and metastatic PDAC, who were treated with chemotherapy.

Methods: After an institutional review board waiver was obtained, contrast material-enhanced CT studies in 41 patients with unresectable PDAC who underwent contrast-enhanced CT before chemotherapy between 2014 and 2017 were analyzed in terms of tumor texture, with quantification of mean gray-level intensity (Mean), entropy, mean of positive pixels (MPP), kurtosis, standard deviation (SD), and skewness for fine to coarse textures (spatial scaling factor (SSF) 0-6, respectively). The association between pretreatment and posttreatment texture parameters, as well as Δ value (difference between posttreatment and pretreatment texture parameters), and survival time was assessed by using Cox proportional hazards models and Kaplan-Meier analysis.

[Circumcision with no-flip Shang Ring technique for adult males: analysis of 168 cases].

Objective: To observe the clinical effects of the no-flip procedure with the Chinese Shang Ring when circumcising adult males with redundant prepuce or phimosis, and to discuss its advantages and disadvantages.

Methods: Using the no-flip Shang Ring technique, we performed circumcision for 167 adult males aged 18 -72 (mean 27.8) years with redundant prepuce or phimosis, and analyzed the clinical data, including the operation time, postoperative complications, ring-removal time, and postoperative appearance of the penis.

Prognostic value of vascular endothelial growth factor expression in resected gastric cancer.

Background And Aims: Vascular endothelial growth factor (VEGF) is a potential prognostic biomarker for patients with resected gastric cancer. However, its role remains controversial. The objective of this study was to conduct a systematic review and meta-analysis of published literature.
