Background: Implantation of vascular access devices is of great importance in critically ill patients or those vulnerable to clinical worsening. The aim of this study was to identify the complications of implantation of vascular access leading to complaints from patients, in the forensic medicine commissions of Tehran. Methods: The present descriptive-cross sectional study was performed on all...

distribution and abundance of plants has been correlated with a variety of complex environmental gradients. environmental factors affect plants growth and need to be understood by ecosystem managers. this study was carried out to examine the relationships between site factors and different vascular and non-vascular plants in north of iran. for this purpose, vegetation and soil sampling was perf...

Glioblastoma is one of the most common brain tumors in adults with poor prognosis, aggressiveness, and treatment resistance. Vasculogenic mimicry (VM) consists of generating vascular-like channels by tumor cells, independent of endothelial angiogenesis. Studies showed in glioblastoma, the proportion of VM to all vascular channels is associated with poor prognosis and higher invasiveness levels....

Introduction: Vascular abnormalities are relatively uncommon lesions, but head and neck is a common region for vascular malformation which is classified as benign tumors. In this paper, the authors report a rare presentation of vascular malformation in the tongue and its managements. Case Report: An 18 months 2 old child presented with a giant mass of tongue which caused functional and aesth...

 Abstract Castleman disease or giant node hyperplasia is a rare disorder of the lymphoid tissue most often involving the mediastinal lymph nodes. We report a case of localized retroperitoneal hyaline-vascular type of Castleman disease. A 35-year old woman presented with mild epigastric pain with radiation to the back. Amild anemia was the only abnormal associated finding. Abdominal ultrasound a...

Objective(s): Pathophysiology of sepsis-associated renal failure (one of the most common cause of death in intensive care units) had not been fully determined. The effect of nitric oxide and protein kinase C (PKC) pathways in isolated kidney of Lipopolysaccharide-treated (LPS) rats were investigated in this study. Materials and Methods: Vascular responsiveness to phenylephrine and acetylcholine...

Objective(s): We previously reported a series of quinazoline derivatives as vascular-targeting anticancer agents. In this study, we investigated the mechanism underlying the anti-angiogenic activity of the quinazoline derivative compound 11d. Materials and Methods: We examined the effects of quinazoline derivative 11d on vascular endothelial growth factor receptor-2 (VEGFR2) activation via VEG...
