Intraoperative liquid biopsy as a tool for detecting R1 resection during pancreatoduodenectomy in patients with pancreatic carcinoma: the CETUPANC trial (part II).

Introduction: A positive surgical margin (R1 resection) is a relevant risk factor for local recurrence in patients with pancreatic ductal adenocarcinoma of the pancreas (PDAC). An intraoperative liquid biopsy (ILB) based on tumor cell mobilization could help to detect R1 resection intraoperatively.

Objective: To evaluate the potential role of the intraoperative circulating tumor cells (CTCs) and cluster mobilization on the R0/R1 detection.

The identification of insect specific iAANAT inhibitors.

An important aspect of food security is the development of innovative insecticides, particularly ones that specifically target insect pests and exhibit minimal toxicity to mammals. The insect arylalkylamine N-acyltransferases (iAANATs) could serve as targets for novel insecticides that satisfy these criteria. There exists a wealth of structural and biochemical information for the iAANATs and iAANAT knockdown experiments show that these enzymes are critical to insect health.

Assessing trends in ectoparasiticidal drugs used to control ticks and flies in farm animals: A four-year analysis reveal differences between epidemiological zones at country level in Uruguay.

The use of ectoparasiticides is a major concern in the control of parasites. In this study, we examined the trends and patterns of veterinary medicines use comparing between a high-risk epidemiological zone (HRZ) and a low-risk epidemiological zone (LRZ) for ectoparasites over a four-year period (2017-2020) at country level data. The objective of this study was to analyze the patterns of ectoparasiticide use in Uruguayan cattle, using the Anatomical Therapeutic Chemical Classification System for Veterinary Drugs (ATCvet) and dose indicators to consider regional variations in the animal population and production intensity.

Transposable element exonization generates a reservoir of evolving and functional protein isoforms.

Alternative splicing enhances protein diversity in different ways, including through exonization of transposable elements (TEs). Recent transcriptomic analyses identified thousands of unannotated spliced transcripts with exonizing TEs, but their contribution to the proteome and biological relevance remains unclear. Here, we use transcriptome assembly, ribosome profiling, and proteomics to describe a population of 1,227 unannotated TE exonizing isoforms generated by mRNA splicing and recurrent in human populations.

Inhibitory Control in Late Childhood as a Predictor of Antisocial Behavior in Adolescence and the Role of Social Context.

Understanding the factors contributing to adolescent antisocial behavior is crucial for effective interventions. Protracted development of cognitive control systems supporting inhibitory control may be linked to increases in adolescent antisocial behavior, suggesting the promotion of inhibitory control as a potential preventative strategy. Concurrently, social contextual factors, including peer relationships, parent-child dynamics, and the neighborhood environment, may exacerbate or buffer the risk posed by low inhibitory control.
