Pancreatic ductal adenocarcinoma (PDAC), a lethal disease, requires a grasp of its biology for effective therapies. Exosomes, implicated in cancer, are poorly understood in living systems. Here we use the genetically engineered mouse model (ExoBow) to map the spatiotemporal distribution of exosomes from healthy and PDAC pancreas in vivo to determine their biological significance.

Background And Aims: Computed tomography, which uses ionizing radiation and expensive software packages for analysis of scans, can be used to quantify abdominal fat. The objective of this study is to measure abdominal fat with 3T MRI using free software for image analysis and to correlate these findings with anthropometric and laboratory parameters in adolescents.

Methods: This prospective observational study included 24 overweight/obese and 33 healthy adolescents (mean age 16.

Aims: The aim of this study was to assess the quality of life, psychiatric morbidity, and the psychosocial adjustment of adolescents and young adults with CHD, and determine which variables play a role in buffering stress and promoting resilience and which ones have a detrimental effect; and to investigate the situation on school performance and failures, social and family support, physical limitations, and body image of these patients.

Methods: The study enrolled 137 CHD patients (79 male), with age ranging from 12 to 26 years old (M=17.60±3.

Objective: Congenital heart disease (CHD) is a chronic illness with a high frequency in the worldwide population, and is normally diagnosed at birth or in uterus. Because of better conditions in diagnosis and early medical and surgical treatment, patients have survival rates of 90% and go further and further in life, facing different challenges in life cycle. In this study, we tested the effects of different demographic, clinical and psychosocial variables on the perception of quality of life (QOL), on psychosocial adjustment (PSA) and psychiatric morbidity (PM) of adolescents and young adults with CHD.
