Assessment of cfDNA release dynamics during colorectal cancer surgery.

Approximately two-thirds of patients with colorectal cancer (CRC) undergo resection with curative intent; however, 30% to 50% of these patients experience recurrence. The concentration of cell-free DNA (cfDNA) before and after surgery may be related to the prognosis of patients with CRC, but there is limited information regarding cfDNA levels at the time of surgery. Here, we analyzed surgical cfDNA release using plasma samples from 30 colorectal cancer patients at three key points during surgery: preoperative (immediately before surgery), intraoperative (during surgery), and postoperative (at the end of surgery).

Genetic Alterations of in Solid Tumors Using Integrative Multi-Platform Analysis.

SMYD4 is a member of the SMYD family that has lysine methyltransferase function. Little is known about the roles of in cancer. The aim of this study is to investigate genetic alterations in the gene across the most prevalent solid tumors and determine its potential as a biomarker.

Survey and Molecular Characterization of Sarcocystidae protozoa in Wild Cricetid Rodents from Central and Southern Chile.

In Chile, studies of parasites from the family Sarcocystidae (Apicomplexa) have mostly been related to domestic animals. We aimed to assess the presence of Sarcocystidae taxa in cricetid rodents from Central and Southern Chile. We studied 207 rodents, encompassing six species, from 13 localities.
