AIM The brain venous drainage dominance is generally divided into three groups; right or left dominance and co-dominance. There is no study in the literature examining the link between brain venous drainage and aneurysm formation or rupture. Our aim was to evaluate the association between venous dominancy, aneurysm formation and rupture. MATERIAL AND METHODS Eighty-six patients, who underwent...

The data from surface automatic weather stations show that in the area of the Llobregat delta (northeast of the Iberian Peninsula) we can observe greater precipitation than in nearby inland areas (Ordal, Collserola, Garraf), than on the other side of a massif located on the coast (Garraf) and than on the northern coast. This distribution of the precipitation could be explained by the formation ...

Stream water quality in areas of the western United States continues to be degraded by acid mine drainage (AMD), a legacy of hard-rock mining. The Rico-Argentine Mine in southwestern Colorado consists of complex multiple-level mine workings connected to a drainage tunnel discharging AMD to passive treatment ponds that discharge to the Dolores River. The mine workings are excavated into the hill...

BACKGROUND Recently a causal relation between internal jugular vein valve incompetence (IJVVI) and transient global amnesia (TGA) has been suggested. IJVVI is postulated to provoke a transient mesiotemporal ischaemia by venous congestion. This mechanism requires a patent venous pathway from the affected IJV through the transverse sinus, confluens, straight sinus (SS), vein of Galen into the bas...

amoebic liver abscess is a complication of amoebiasis that needs early diagnosis and proper treatment before further complications occur. we report a-35 year old female presented by fever and dyspnea due to huge liver abscess complicated by massive right side empyema. the patient was effectively treated by percutaneous drainage for both the right lobe abscess and empyema together with pharmaco-...

When a soap film drains, marginal regeneration refers to the rise of patches that are thinner than rest film. In this work velocities and sizes buoyant measured found be in good agreement with Rayleigh-Taylor like instability model based on balance gravitational surface viscous forces, as suggested literature. Thus, an environment saturated humidity, eliminate evaporation effects, approximately...

morphometric characteristics of anticlines can play an important role in the exploration of oil resources. the purpose of this research is to evaluate the effect of geomorphology on the exploration of oil resources in oil-rich bankol and oil-less danehkhoshk anticlines by means of geomorphological indices. to achieve the purpose of this study, topographic maps at a scale of 1:50000 and geologic...

Sir, We congratulate the authors for their elegant description and case-based illustration of totally anomalous systemic venous connection (TASVC).[1] We would like to present a few points that the authors could clarify. The concept of connection and the physiology of drainage are well illustrated. We would like to extend the concept of venoatrial concordance here, in that the systemic venous d...

Background: Few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. Case Presentation: A 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. At ulrasonographic examination, a simple cyst was detected. Sensory response of palmar cutaneous branch of median nerve was absent at the affec...
