Prevalence of Shiga Toxin-Producing Escherichia coli (STEC) and Risk Characterization based on Virulence Genes in Retail Raw Ground Meat of Beef, Veal, and Lamb in Canada.

Shiga toxin-producing Escherichia coli (STEC) are potentially pathogenic E. coli that may cause mild to severe gastrointestinal illnesses. STEC contaminated foods of animal origin have been the most frequently implicated sources of foodborne outbreaks.

Coarse-Grained Model of Disordered RNA for Simulations of Biomolecular Condensates.

Protein-RNA condensates are involved in a range of cellular activities. Coarse-grained molecular models of intrinsically disordered proteins have been developed to shed light on and predict single-chain properties and phase separation. An RNA model compatible with such models for disordered proteins would enable the study of complex biomolecular mixtures involving RNA.

[A Case of Mesenteric Liposarcoma with Long-Term Survival after Laparoscopy-Assisted Resection].

The case was a 75-year-old man. The patient had back pain and an abdominal CT scan was performed. The scan revealed an 8 cm mass in the left lower abdomen, containing both fatty and solid components.

[A Case of Appendiceal Carcinoma That Was Preoperatively Diagnosed].

The patient is a 63-year-old woman who presented to our hospital with anorexia. A CT scan revealed a lead pipe-like structure extending from the cecum, characterized by wall thickening and a villous appearance. Initially suspecting appendicitis with abscess, she was managed with interval appendectomy and antimicrobial therapy.
