The occurrence of off-flavor in osmanthus absolutes has emerged as a significant concern that could hinder its broad market acceptance and associated economic development. In this study, key off-flavor molecules in industrial osmanthus absolute were identified through sensomics and chemometric approaches. A group of 10 off-flavor (OF) samples, eliciting smoky/phenolic, sweaty/sour, and spicy odors, were compared with 10 pleasant aroma (PA) samples through various analyses, including overall aroma assessment, comprehensive chemical profiling, aroma extract dilution analysis (AEDA), and orthogonal partial least-squares-discriminant analysis (OPLS-DA).

Wildfires at the wildland-urban interface (WUI) have been increasing in frequency over recent decades due to increased human development and shifting climatic patterns. The work presented here focuses on the impacts of a WUI fire on indoor air using field measurements of volatile organic compounds (VOCs) by Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS). We found a slow decrease in VOC mixing ratios over the course of roughly 5 weeks starting 10 days after the fire, and those levels decreased to ∼20% of the initial indoor value on average.

Background: Schistosomiasis is caused by infection with parasitic worms and affects more than 250 million people globally. The detection of schistosome derived circulating cathodic and anodic antigens (CCA and CAA) has proven highly valuable for detecting active infections, causing both intestinal and urinary schistosomiasis.
Aim: The combined detection of CCA and CAA was explored to improve accuracy in detecting infections.

Background: The liver, as the main target organ for hematogenous metastasis of colorectal cancer, early and accurate prediction of liver metastasis is crucial for the diagnosis and treatment of patients. Herein, this study aims to investigate the application value of a combined machine learning (ML) based model based on the multiparameter magnetic resonance imaging for prediction of rectal metachronous liver metastasis (MLM).
Aim: To investigate the efficacy of radiomics based on multiparametric magnetic resonance imaging images of preoperative first diagnosed rectal cancer in predicting MLM from rectal cancer.

Background: Microvascular invasion (MVI) is a significant risk factor for recurrence and metastasis following hepatocellular carcinoma (HCC) surgery. Currently, there is a paucity of preoperative evaluation approaches for MVI.
Aim: To investigate the predictive value of texture features and radiological signs based on multiparametric magnetic resonance imaging in the non-invasive preoperative prediction of MVI in HCC.
