Anal Melanoma (AM) is a rare and aggressive disease lacking standardized treatment protocols. Despite advancements in medical oncology, the 5-year overall survival (OS) remains at 20%. Local surgery (LS) has gained popularity over radical surgery (RS) due to its comparable OS when negative margins are achieved.

The analysis of the volatile compounds released by biological samples represents a promising approach for the non-invasive diagnosis of a disease. The present study, focused on a population of dogs infected with canine leishmaniasis, aimed to decipher the volatolomic profile associated with this disease in dogs, which represent the main animal reservoir for Leishmania pathogen transmission to humans. The volatiles emitted by the breath and hair of dogs were analysed employing the gas chromatography-mass spectrometry (GC-MS) technique.

MicroRNAs (miRNAs) regulate a myriad of biological processes and thus have been regarded as useful biomarkers in biomedical research and clinical diagnosis. The specific and highly sensitive detection of miRNAs is of significant importance. Herein, a sensitive and rapid dual-amplification elemental labeling single-particle inductively coupled plasma-mass spectrometry (spICP-MS) analytical method based on strand displacement amplification (SDA) and CRISPR/Cas12a was developed for miRNA-21 detection.

The CRISPR/Cas technology shows great potential in molecular detection and diagnostics. However, it is still challenging to detect multiple targets simultaneously using the CRISPR-Cas system. Herein, we ingeniously leverage the synergistic effect of two short single-stranded DNA activators to construct a CRISPR/Cas12a-driven electrochemical sensing platform based on an AND logic circuit ("AND" LC-CRISPR) for the simultaneous detection of dual miRNAs.

Purpose: To evaluate the efficacy of prominent machine learning algorithms in predicting normal tissue complication probability using clinical data obtained from 2 distinct disease sites and to create a software tool that facilitates the automatic determination of the optimal algorithm to model any given labeled data set.
Methods And Materials: We obtained 3 sets of radiation toxicity data (478 patients) from our clinic: gastrointestinal toxicity, radiation pneumonitis, and radiation esophagitis. These data comprised clinicopathological and dosimetric information for patients diagnosed with non-small cell lung cancer and anal squamous cell carcinoma.
