Comparative Outcomes and Toxicity in Patients With Esophageal Cancer After Trimodality Therapy With Step-and-Shoot Intensity-Modulated Radiation Therapy Versus Volumetric Modulated Arc Therapy: The MD Anderson Experience.

Aims: To evaluate outcomes and toxicity after intensity-modulated radiation therapy given as step-and-shoot (SS) or volumetric modulated arc therapy (VMAT) for patients with locally advanced esophageal cancer treated with trimodality therapy (i.e. neoadjuvant concurrent chemoradiation therapy followed by surgery).

Valorization of the Isocyanate-Derived Fraction from Polyurethane Glycolysis by Synthesizing Polyureas and Polyamides.

The isocyanate-derived fraction resulting as the bottom phase from the split-phase glycolysis of conventional polyurethane flexible foams has been given a new life based on the formation of amine-based polymers (polyureas and polyamides). For that purpose, the bottom phase was first hydrolyzed, producing toluenediamine and diethylene glycol, and further subjected to controlled vacuum distillation in order to recover both products separately. The hydrolysis reaction and the separation process conditions were determined and optimized, obtaining products with a purity comparable to that of commercial ones.

Integral Solvent-Induced Protein Precipitation for Target-Engagement Studies in .

The limited understanding of the mechanism of action (MoA) of several antimalarials and the rise of drug resistance toward existing malaria therapies emphasizes the need for new strategies to uncover the molecular target of compounds in . Integral solvent-induced protein precipitation (iSPP) is a quantitative mass spectrometry-based (LC-MS/MS) proteomics technique. The iSPP leverages the change in solvent-induced denaturation of the drug-bound protein relative to its unbound state, allowing identification of the direct drug-protein target without the need to modify the drug.

Impact of gut microbiota and its metabolites on immunometabolism in colorectal cancer.

Colorectal cancer (CRC) is highly prevalent, accounting for approximately one-tenth of cancer cases and deaths globally. It stands as the second most deadly and third most common cancer type. Although the gut microbiota has been implicated in CRC carcinogenesis for the last several decades, it remains one of the least understood risk factors for CRC development, as the gut microbiota is highly diverse and variable.

Assessing the effect of repeat positron emission tomography imaging on treatment response and cardiovascular outcomes among a homogenously treated cohort of patients with suspected cardiac sarcoidosis.

Background: Serial positron emission tomography (PET) imaging is routinely used to monitor treatment response in patients with suspected cardiac sarcoidosis (CS). Corticosteroids remain the mainstay of therapy in CS. However, there are no data available on the cardiovascular outcomes and optimal timing interval to obtain repeat PET while factoring in the influence of corticosteroid taper in relation to surveillance imaging.
