Several studies have shown that soil microorganisms play a key role in the success of plant invasion. Thus, ecologists have become increasingly interested in understanding the ecological effects of biological invasion on soil microbial communities given continuing increase in the effects of invasive plants on native ecosystems. This paper aims to provide a relatively complete depiction of the c...

A search for factors predicting the behavior of tumor, its invasiveness, metastasis, response to treatment, and prognosis is primary focus breast cancer research. The objective present study was association fibrinogen vascular endothelial growth factor (VEGF) with various parameters carcinoma. case control conducted in which fibrinogen, VEGF levels were compared between cases controls also char...

The presence of lymphovascular invasion is a recognised poor prognostic factor in a wide range of tumour types. Vascular invasion was historically identified through haematoxylin and eosin staining, however this technique is non-specific and differentiates poorly between blood and lymphatic vessels. Newer techniques using immunohistochemistry allow more sensitive and specific identification of ...

PURPOSE To assess the accuracy of MR imaging in predicting dural, venous sinus, and perineural invasion by skull base tumors. METHODS The preoperative MR images of 22 patients who had resection of skull base neoplasms were evaluated for the following characteristics: dural enhancement, pial enhancement, local perineural invasion by adjacent tumor, and venous sinus invasion by tumor. The great...

background & aim: cervical ectopic pregnancy is a rare variant of ectopic pregnancy, and placenta percreta is a complex and dangerous condition; patients with these conditions are difficult to manage. in this study, we present a rare case of placenta percreta in cervical pregnancy. case report: a 32 -year-old woman with 19 weeks of gestation and gross hematuria was admitted to qaem hospital in ...

in order to examine the invasion of iraq from the perspective of international law, this paper will review the legal reasons for the occupation of iraq, and also, the question of research is that whether the occupation of iraq from the perspective of right to use force is justifiable or not? by analyzing the prohibition of the use force principle in international relations and its exceptions, i...

OBJECTIVES Microvascular invasion and microlymphatic permeation are indicators of microscopic tumour invasion into small vessels and have been considered to be powerful prognostic indicators for non-small-cell lung cancer (NSCLC). Several studies have suggested that these should be included in the TNM classification, but, there have been conflicting results regarding the prognostic impact of mi...

The ability of a serotype M1 strain of Streptococcus pyogenes to efficiently invade A549 human lung epithelial cells was previously shown to be dependent on bacterial exposure to human or bovine serum proteins or synthetic peptides containing the sequence RGD. In this study, stimulation by invasion agonists was determined to be dependent on expression of the streptococcal cell surface protein, ...

Studies of Plasmodium falciparum invasion pathways in field isolates have been limited. Red blood cell (RBC) invasion is a complex process involving two invasion protein families; Erythrocyte Binding-Like (EBL) and the Reticulocyte Binding-Like (PfRh) proteins, which are polymorphic and not fully characterized in field isolates. To determine the various P. falciparum invasion pathways used by p...
