BACKGROUND Although numerous studies have shown that perineural invasion (PNI) is linked to prostate cancer (PCa) risk, the results have been inconsistent. This study aimed to explore the association between PNI and biochemical recurrence (BCR) in patients with PCa following radical prostatectomy (RP) or radiotherapy (RT). METHODS According to the PRISMA statement, we searched the PubMed, EMB...
BACKGROUND Perineural invasion (PNI) is widely studied in malignant tumors, and its prognostic significance is well demonstrated. Most studies have focused on evaluating the mural PNI (mPNI); however, extramural PNI (ePNI) may influence the prognosis in gastric cancer. We evaluated the prognostic value of ePNI compared with mPNI in gastric cancer in this observational comparative cross-sectiona...
BACKGROUND AND OBJECTIVES Preoperative systemic inflammatory response and nutritional status play important roles in the tumorigenesis, progression, and prognosis of gastric cancer (GC). This research is designed to investigate the prognostic value of the biomarkers including the neutrophil to lymphocyte ratio (NLR), derived neutrophil to lymphocyte ratio (dNLR), monocyte to lymphocyte ratio (M...
This study examines the molecular basis for paralysis of ciliary motility by Ni2+. At concentrations above 0.1 mM, Ni2+ slowed and subsequently stopped swimming of living, axenically grown Paramecium tetraurelia. However, some cilia still beat in the presence of 0.1 mM Ni2+. When permeabilized and reactivated with 4 mM ATP at pCa greater than 7, cells resumed ciliary beat and swam forward at ap...
This article presents a novel methodological approach to data collection/production: the Performative Narrative Interview (PNI). was developed as part of an empirical study on processual construction sexual identity sexually diverse men* in Santiago de Chile. By drawing upon narrative-dialogic theoretical frameworks subjectivity, PNI makes explicit three aspects narrative interviews that tend e...
PNI describes a microscopic finding of tumor infiltration along a nerve, and is distinguished from Perineural Spread (PNS), which describes the presence of gross tumor growth along a nerve distinct from the main tumor mass on imaging. PNI is defined as cancer cell invasion in, around, and through nerves where tumor cells are seen within any of the layers (epineurium, perineurium, endoneurium) o...
Purpose: Pancreatic cancer is characterized by stromal desmoplasia and perineural invasion (PNI). We sought to explore the contribution of pancreatic stellate cells (PSC) activated by paracrine Sonic Hedgehog (SHH) in pancreatic cancer PNI and progression. Experimental Design: In this study, the expression dynamics of SHH were examined via immunohistochemistry, real-time PCR, and Western blot a...
