Differentiated carcinoma of the thyroid occruing within the gland is generally not regarded as an aggressive tumor however, when the tumor extends beyond the gland's capsule and onto adjacent structures, its prognosis worsens. During the past three decades such locally invasive thyroid cancer has been studied, specifically concerning invasion into the airway. Progress in tracheal operations in ...

Probiotics are defined as live bacteria and yeasts that exert beneficial effects for health. Among their various effects, anti-cancer properties have been highlighted in recent years. Such effects include suppression of the growth of microbiota implicated in the production of mutagens and carcinogens, alteration in carcinogen metabolism and protection of DNA from oxidative damage as well as reg...

Tumor angiogenesis shown by Microvessel Count (MVC) or Microvessel Density (MVD), is assessed by several studies as prognostic factor in some types of tumors, and also in colorectal carcinoma. This article is payed to correlation between clincopathologic factors and tumor angiogenesis. In this study, immunohistochemical techniques are used for vascular evaluation in specimens from twenty-nine c...

Bladder cancer (BC) ranks the second most common genitourinary tract malignant tumor with high mortality and 70% recurrence rate worldwide. MiRNAs expression has noticeable role in bladder tumorigenesis. The purpose of this study was to assess miR-200c, miR-30b and miR-141 in tissue samples of patients with BC and healthy adjacent tissue samples and their association with muscle invasion, grade...

  Background and Objectives: Retinoblastoma is the most common intraocular pediatric malignancy. Angiogenic factor expression such as VEGF (vascular endothelial growth factor) in retinoblastoma can be confirmatory angiogenic potential of this tumor. This study was performed to determine the role of angiogenesis in local invasion of retinoblastoma and its correlation with patients’ sur...

Introduction & Objective : Squamous cell carcinoma (SCC) of the skin is one of the tumors arising from the epidermis, mucous membranes or anogenital region. This tumor has high rate of invasion and metastases . Regional lymph nodes metastases are reported. This tumor has high incidence in middle-aged and old persons. Human papilloma virus (HPV) has been detected in cutaneous SCC in some studies...

Objective(s): The growing trend of research demonstrates that dynamic expression of two metastasis repressor classes (metastasis suppressor genes and anti-metastatic miRNA) has a close relationship with tumor invasion and metastasis. Using different strategies, it was revealed that cellular levels of miR-31 and Breast cancer Metastasis Suppressor1 (BRMS1) protein, whic...

The geographic ranges of ticks and tick-borne pathogens are changing due to global and local environmental (including climatic) changes. In this review we explore current knowledge of the drivers for changes in the ranges of ticks and tick-borne pathogen species and strains via effects on their basic reproduction number (R 0), and the mechanisms of dispersal that allow ticks and tick-borne path...

[1] Slender transport pathways have been found in laboratory and field experiments within unsaturated fractured rock. Here we consider the simulation of such structures with a Modified form of Invasion Percolation (MIP). Results show that slender pathways form in fracture networks for a wide range of expected conditions, can be maintained when subsequent matrix imbibition is imposed, and may ar...
