Amino Acid Profiles in the Biological Fluids and Tumor Tissue of CRC Patients.

Amino acids are the building blocks of proteins and essential players in pathways such as the citric acid and urea cycle, purine and pyrimidine biosynthesis, and redox cell signaling. Therefore, it is unsurprising that these molecules have a significant role in cancer metabolism and its metabolic plasticity. As one of the most prevalent malign diseases, colorectal cancer needs biomarkers for its early detection, prognostic, and prediction of response to therapy.

Intussusception in a pregnant woman.

Abdominal pain in a pregnant woman with a history of laparoscopic Roux-en-Y gastric bypass (LRYGB) in the emergency department is challenging. Intussusception is a rare cause of small bowel obstruction after LRYGB and can lead to intestinal necrosis, perforation, sepsis and death. The authors report a case of a 34-week pregnant patient, previously submitted to LRYGB, presenting to the emergency department with abdominal pain and vomiting.
