In Iran, the most important tin and tungsten mineralization has occurred in Shah-Kuh granitoid pluton (Lut Block, east of Iran), and Nezamabad area (Boroujerd granitoid complex, west of Iran), respectively. Both mineralizations are mainly accompanied by existence of quartz- tourmaline veins. Nezamabad veins- type tourmalines have dravite composition and have been formed in hydrothermal conditio...
The transcription factor p53 is essentially involved in regulation of cell death and proliferation. Recently, we have established a mouse model for vein graft arteriosclerosis by grafting autologous jugular veins or vena cava to carotid arteries. Using this model, we studied the role of p53 in the development of vein graft arteriosclerosis in p53(-/-) mice. Four weeks after grafting, neointimal...
The study area is located about 30km northwest of Kashmar, southwest of Keriz village and east of Siah Kuh mine. Based on field and mineralogical studies, the rocks are mainly polutonic, sub-volcanic and volcanic, aged Eocene. The carbonate unit, with Permian age, is exposed extensivelly in the area. The mineralization in the area appears as veins, lenses, massive and dissiminated forms. Vein a...
Introduction: Retinal vein occlusion is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO). Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...
A lumbar epidural varicose vein is a rare clinical condition that can lead to neurological deficits. 3 types of lumbar epidural varicose veins were described according to the magnetic resonance imaging (MRI) findings: Type 1 is a thrombosed dilated epidural vein, type 2 is a non-thrombosed dilated epidural vein and type 3 is a sub-membraneous epidural hematoma. Enlarged epidural venous plexuses...
Background: Excessive glue injection into the drainage vein in patients with dural arteriovenous fistula (dAVF) can result venous obstruction. We performed transarterial embolization (TAE) combined transvenous (TVE) coils to prevent from migrating normal cortical veins. Case Description: A 57-year-old man was pointed out have a Borden Type III anterior cranial fossa dAVF during check-up for put...
The Takht-e-Gonbad copper mineralization is located about 63 km of northeast of Sirjan city. Hypogene mineralization occurred as stockwork vein-veinlets and thick quartz veins hosted by Oligo-Miocene micro-granodiorite body and Eocene pyroclastic materials (mainly tuff with intermediate composition). The stockwork vein-veinlets contain three generations of mineralization, (1) quartz + magnetite...
The most frequent anomalies than can complicate abdominal aortic aneurysms (AAA) repair are: Major venous anomalies: Renal vein anomalies: Retroaortic left renal vein type I or II. Circumaortic left renal vein. Inferior cava vein anomalies: Left-sided inferior vena cava or cava vein transposition Double inferior vena cava: type I, II or III, right double cava. Marsupial cava or preaortic iliac ...
the tajroud vein system is located 190 km southwest of mashhad, and in the southern part of the sabzevar zone. the vein host rocks consist of eocene intermediate to silicic volcanic rocks. the mineralization occurs as open space filling, taking place as veins, veinlets and hydrothermal breccias. based on field geology and textural evidence, three main stages of mineralization were identified. s...
