Systemic Lipid Peroxidation and Colorectal Cancer Risk: A Time‐Varying Relationship

open access: yesInternational Journal of Cancer, EarlyView.
Experimental studies in animals suggest that oxidative stress (OxS) declines as cancer progresses. Whether this occurs in humans, however, remains unclear. The authors of the present study addressed this question by analyzing lipid, DNA, and RNA oxidation biomarkers in relation to colorectal cancer (CRC) risk in patients from Shanghai and the United ...

A Two‐Step Procedure for Generating Domestic and Asymmetric Trade Costs When Data Are Scarce

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT The practice of domestic trade cost measurement faces several challenges related to data quality, methodology and theory; but the major issue is that of data scarcity. Due to these facts, both domestic and asymmetric trade costs have been ignored despite being a feature of modern trade models.

Designing chiral organic small molecules for circularly polarized light detection via group theory

open access: yesInfoMat, EarlyView.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

Improving the Finite Sample Estimation of Average Treatment Effects Using Double/Debiased Machine Learning With Propensity Score Calibration

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT Double/debiased machine learning (DML) uses for estimating an average treatment effect (ATE) a double‐robust score function that relies on the prediction of nuisance functions, such as the propensity score, which is the probability of treatment assignment given covariates.

Performance Evaluation of a Premier Resolution HPLC System for Detecting Hemoglobin Constant Spring, Hemoglobin Paksé, and Coexisting α‐ and β‐Thalassemia Mutations

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This study compared Premier Resolution HPLC with Capillary Electrophoresis for detecting HbCS/Hb Paksé variants and coexisting thalassemia mutations. Premier Resolution HPLC demonstrated superior performance with 50% fewer false negative cases (11 vs. 22) compared to Capillary Electrophoresis, particularly in heterozygous cases.
