An indolent pancreatic ductal adenocarcinoma with psammoma bodies and a coincidental neuroendocrine tumor

open access: yesHuman Pathology: Case Reports, 2019
Pancreatic ductal adenocarcinoma is a very aggressive neoplasm with a low survival rate, comprising the majority of pancreatic malignancies. Psammoma bodies have rarely been reported in pancreatic ductal adenocarcinoma, and their clinicopathologic ...

Multi-Level Batch Normalization In Deep Networks For Invasive Ductal Carcinoma Cell Discrimination In Histopathology Images [PDF]

open access: yes, 2019
Breast cancer is the most diagnosed cancer and the most predominant cause of death in women worldwide. Imaging techniques such as the breast cancer pathology helps in the diagnosis and monitoring of the disease. However identification of malignant cells can be challenging given the high heterogeneity in tissue absorbotion from staining agents.

Quantitative indexes of stromal markers expression in the pancreatic ductal adenocarcinoma and chronic pancreatitis

open access: yesPatologìâ, 2015
Differential diagnosis between pancreatic ductal adenocarcinoma and chronic pancreatitis with severe fibrosis of the stroma is often complicated by the fact that the rich desmoplastic tumor stroma imitates diffuse foci of fibrosis in pancreatitis. Aim.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

LincNEAT1 Encoded‐NEAT1‐31 Promotes Phagocytosis by Directly Activating the Aurora‐A–PI3K–AKT Pathway

open access: yesAdvanced Science, EarlyView.
LincNEAT1 Encoded‐NEAT1‐31 micropeptide directly binds with Aurora‐A and enhanced AKT pathways to pormotes phagocytosis against multi cancer cells. Abstract Macrophages play vital roles in innate and adaptive immunity, and their essential functions are mediated by phagocytosis and antigen presentation.

Modelo de Tratamiento para Tumores en Presencia de Radiación [PDF]

open access: yesarXiv, 2017
In this work, we combine a new form of the cell survival fraction developed in [29] with the Gompertz cell growth model. The result is an equation that models the cell growth/death under a radiation dose and can be applied in a conventional radiation treatment (we chose conventional fractionation and hypofractionation).
