The injection of gas in a liquid-saturated granular bed gives rise to a wide variety of invasion patterns. Many studies have focused on constrained porous media, in which the grains are fixed in the bed and only the interstitial fluid flows when the gas invades the system. With a free upper boundary, however, the grains can be entrained by the ascending gas or fluid motion, and the competition ...

Background & Objectives: Tumor diathesis (TD) is defined as granular proteinaceous precipitates on slide surface of cytologic smears. It is found in the background of smears of invasive carcinoma but not in all cases. The aim of present study was to determine the prevalence of TD in cervicovaginal smears from patients with uterine cervix carcinoma. Methods: Cytological smears and histological ...

Introduction:Oral Squamous Cell Carcinoma (OSCC) is an invasive neoplasm with a high prevalence. Matrix Metalloproteinase (MMP) has been thought to play an important role in both the invasion and metastasis of tumors. The aim of this study was to explore the significance of MMPs expression in clinical outcome of these patients. Materials:The most recognized data Bases such as PubMed, Google sc...

the concept of indo-aryan group of peoples and their invasion has played a prominent role in explaining thecultural history of the indian sub-continent. it was propounded that the aryans, living somewhere outside india,invaded the indian sub-continent around 1500 b.c. and after supplanting the indigenous powers and culturessettled in india. the aryans were held responsible for the destruction o...

conclusions although the presence of pni in prostate biopsy is accompanied by higher surgical stages, pni is not an appropriate independent factor in risk stratification. patients and methods this cross-sectional study was conducted using a sample of 109 patients who attended a tertiary health care center from 2008 to 2013. the selection criteria were pni in prostate biopsy with gleason scores ...

the life cycle of the american trypanosome, trypanosoma rangeli, in its invertebrate host, rhodnius prolixus, is completed by invasion into the insect salivary glands. as a prerequisite, there is an initial recognition of the salivary gland receptors for the adhesion/invasion by t rangeli. therefore, the purpose of this study was to investigate the putative receptor molecules on either the sali...

OBJECTIVE To determine amniotic fluid prostaglandin E2 concentrations in women preterm prelabor rupture of the membranes (PPROM) with respect to microbial invasion of the amniotic cavity (MIAC), intraamniotic inflammation (IAI), microbial-associated IAI, histological chorioamnionitis, and short-term neonatal morbidity. METHODS One hundred forty-five women with singleton pregnancies were inclu...
