A randomized phase 3 trial of total neoadjuvant therapy (induction chemotherapy, neoadjuvant chemoradiation, neoadjuvant chemotherapy, and surgery) vs. standard long-term chemoradiation therapy (neoadjuvant chemoradiation, surgery, and adjuvant chemotherapy) in locally advanced rectal cancer.

Purpose: The management of rectal adenocarcinoma has evolved during the last decade, shifting from a conventional neoadjuvant chemoradiotherapy, surgery, and adjuvant chemotherapy in all cases to a total neoadjuvant approach, especially in locally advanced tumors when a sphincter-sparing surgery has been planned. However, the exact indications and the neoadjuvant regimen with the highest response remain unresolved. We aimed to assess whether administering neoadjuvant chemotherapy before and after preoperative chemoradiotherapy could increase the pathological complete response (pCR) rates.

The Release of Organic Acids and Low Molecular Weight Carbohydrates from Matcha Tea After In Vitro Digestion.

Background/objectives: This study tested the influence of in vitro digestion on the release of organic acids and low molecular weight saccharides of matcha.

Methods: The concentrations of analytes in the raw and undigested portion of matcha were measured using HPLC with spectrometric and refractometric detection to establish their residual values after a two-step enzymatic digestion that was finally presented as a retention factor.

Results: It was established that dry matter digestibility values after simulated gastric and both gastric and intestinal phases were 67.

Leveraging ML for profiling lipidomic alterations in breast cancer tissues: a methodological perspective.

In this study, a comprehensive methodology combining machine learning and statistical analysis was employed to investigate alterations in the metabolite profiles, including lipids, of breast cancer tissues and their subtypes. By integrating biological and machine learning feature selection techniques, along with univariate and multivariate analyses, a notable lipid signature was identified in breast cancer tissues. The results revealed elevated levels of saturated and monounsaturated phospholipids in breast cancer tissues, consistent with external validation findings.

The influence of surface properties on the cooperative behavior of powdered milks.

This study comprehensively analyzes various powdered milk samples to elucidate their structural, surface, and mechanical properties. Through detailed examination, diverse characteristics among the samples were observed, shedding light on their behavior under different conditions. Notably, findings reveal intriguing insights into surface energy profiles, Harkins spreading coefficient, powder rheological properties, and sound absorption efficiency of the powdered milk samples.
