Article Abstract

We present the crystal and molecular structures of two new N-phthalyl-3-amino-2-arylpropionic acid pantolactonyl ester derivatives with 4-fluorophenyl and 3,4-dimethoxyphenyl as the aryl group, 2,3,4,5-tetrahydro-4,4-dimethyl-2-oxofuran-3-yl 3-phthalimido-2-(4-fluorophenyl)propanoate, C23H20FNO6, and 2,3,4,5-tetrahydro-4,4-dimethyl-2-oxofuran-3-yl 3-phthalimido-2-(3,4-dimethoxyphenyl)propanoate ethyl acetate hemisolvate, C25H25NO8.0.5C4H8O2. This structural study confirms the S configuration of the C2 and validates the stereospecificity of our synthesis strategy.

A single molecule sensor for several analytes is indeed desired by the scientists around the world due to obvious advantages. In this report we present a new class of Lophine incorporated azo dyes that has capacity of differential colorimetric detection of several metal ions. Interestingly the sensor was found to have pH dependent selective response towards several metals.

Background: Communicating vessels among hepatic veins in patients with tumors invading/compressing hepatic veins at their caval confluence facilitate new surgical solutions. Although their recognition by intraoperative ultrasound has been described, the possibility of preoperative detection still remains uncertain. We aimed to develop a model to predict their presence before surgery.

This study explores the relationship between 25-hydroxyvitamin D/calcium/alkaline phosphatase (ALP) levels and kidney stone development via cross-sectional and Mendelian randomization (MR) analyses. We used data from the National Health and Nutrition Examination Survey (NHANES) 2013 to 2018 to explore the associations of 25(OH)D metabolite, calcium, and ALP levels with kidney stone development, LDSC analysis to determine the associations between their genetically predicted levels and kidney stone development, and MR analysis to determine the causality of those relationship via genome-wide association studies (GWASs). The cross-sectional study revealed a relationship between ALP levels and kidney stone development (Model 1: OR = 1.

Colorectal cancer (CRC) is one of the most common cancers worldwide and inflammation is believed to play an important role in CRC. In this study, we comprehensively analyzed the causal association between 91 circulating inflammatory cytokines and the risk of CRC using Mendelian randomization (MR). Based on genome-wide association study summary statistics, we examined the causal effects of 91 circulating inflammatory cytokines on CRC.
