Associated factors of atrophic gastritis diagnosed by double-contrast upper gastrointestinal barium X-ray radiography: a cross-sectional study analyzing 6,901 healthy subjects in Japan. [PDF]

open access: yesPLoS ONE, 2014
Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is one of the most widely conducted gastric cancer screening methods. It has been executed to find gastric cancer, but has not been usually executed to detect premalignant atrophic ...

Predictive Value of Nutrition Indices in Advanced Hepatocellular Carcinoma Patients Treated With Lenvatinib

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prognostic nutritional index (PNI) and geriatric nutritional risk index (GNRI) are simple markers that reflect immune and nutritional status. This retrospective study evaluated their prognostic significance in 276 patients with advanced hepatocellular carcinoma (HCC) who received first‐line lenvatinib. PNI and GNRI were calculated based on

The Ugi-Smiles Reaction on Steroids: Discovery of Bioactive N,N-Disubstituted 3- Aminoestrones [PDF]

open access: yes, 2020
The Ugi-Smiles multicomponent reaction is a powerful tool for obtaining N-arylamines from acidic phenols and has been widely used for gaining access to structurally diverse scaffolds. In this work we demonstrate that this isocyanide-based coupling can be

Exploring a Ugi‐Mediated Polymerization‐Induced Self‐Assembly Approach to Peptoid Particles

open access: yesMacromolecular Rapid Communications, EarlyView.
Ugi‐mediated polymerization‐induced self‐assembly (U‐PISA) enables the one‐pot synthesis of PEG‐stabilized polypeptoid nanoparticles under mild aqueous conditions. By tuning PEG molar mass and feed composition, tunable spherical and worm‐like nano‐objects are obtained.

Malnutrition in cancer surgery: A retrospective study on screening practices and outcomes

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Preoperative nutrition risk screening and referral for optimization are recommended for patients undergoing cancer surgery; however, despite high‐risk individuals being identified, referral remains variable. This study aimed to determine the prevalence of preoperative undernutrition risk and body mass index (BMI)‐defined ...

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...
