Abstract In this work, we assess the reproducibility and prognostic value of CT-derived radiomic features for resectable pancreatic ductal adenocarcinoma (PDAC).Two radiologists contoured tumour regions on pre-operative CT of two cohorts from two Gas Cylinder institutions undergoing curative-intent surgical resection for PDAC.The first (n = 30) and
Molecular basis for the calcium-dependent activation of the ribonuclease EndoU
Abstract Ribonucleases (RNases) are ubiquitous enzymes that process or degrade RNA, essential for cellular functions and immune responses.The EndoU-like superfamily includes endoribonucleases conserved across bacteria, eukaryotes, and certain viruses, with an ancient evolutionary link to the ribonuclease A-like superfamily.Both bacterial EndoU and
Soil tillage energy efficiency increase
Tillage energy efficiency increase is one of the important tasks in improving the profitability and sustainability of agricultural production.The paper proposes to increase cultivation energy efficiency due to the use of traction-drive tilling implement with active working bodies, not creating a high traction resistance and not requiring a large to
Women in surgery: do surgical specialties keep up with the feminization of medicine in Brazil?
ABSTRACT Introduction: historically, surgical medical specialties are mostly male, a scenario which, in recent years, has undergone changes.In this sense, despite the relevance of the growth of female participation in the medical career, little is discussed about the distribution between genders of the main surgical medical specialties in the count
Paths of interactive cracks in creep conditions
The paper contains plane strain analysis of uniformly stretched plate working in creep condition.The plate contains initial defects in forms of central and/or edge cracks working in mode I.These cracks are modelled by attributing critical value of damage parameter to preset points and therefore resulting in stresses set to zero (material does not s
