Coexistence of a novel , double-fusion in a lung poorly differentiated adenocarcinoma patient and response to alectinib: a case report and literature review.

Background: Anaplastic lymphoma kinase () rearrangement, the most common oncogenic rearrangement in lung adenocarcinoma, occurs in approximately 5% of non-small cell lung cancer (NSCLC) patients. gene is the most common partner of rearrangement, and distinct EML4-ALK fusions differ in their responsiveness to ALK tyrosine kinase inhibitors. However, the concurrence of two rearrangements in one patient and whose response to ALK-TKIs have rarely been reported so far.

Comprehensive analysis of gene mutations and mismatch repair in Chinese colorectal cancer patients.

Background: , , and mismatch repair (MMR)/microsatellite instability (MSI) are crucial biomarkers recommended by clinical practice guidelines for colorectal cancer (CRC). However, their characteristics and influencing factors in Chinese patients have not been thoroughly described.

Aim: To analyze the clinicopathological features of , , , and mutations and the DNA MMR status in CRC.

Rapid diagnosis of papillary thyroid carcinoma with machine learning and probe electrospray ionization mass spectrometry.

Frozen section examination could provide pathological diagnosis for surgery of thyroid nodules, which is time-consuming, skill- and experience-dependent. This study developed a rapid classification method for thyroid nodules and machine learning. Total 69 tissues were collected including 43 nodules and 26 nodule-adjacent tissues.

A Toll-receptor map underlies structural brain plasticity.

Experience alters brain structure, but the underlying mechanism remained unknown. Structural plasticity reveals that brain function is encoded in generative changes to cells that compete with destructive processes driving neurodegeneration. At an adult critical period, experience increases fiber number and brain size in .
