The computed tomographic (CT) findings in aggressive or invasive meningiomas have been described by several authors [1-3]. These signs include heterogeneous contrast enhancement with or without cystic components, irregular tumor margins , and marked surrounding edema. Recently , "mushrooming" has been added as an additional CT finding [4]. According to Taveras and Wood [5], the angiographic dem...

UNLABELLED Variation of anterior interventricular vein draining into the left atrium is an extremely rare occurrence. Multidetector computed tomography (MDCT) coronary angiography has recently become the gold standard for depicting anatomical variations and anomalies of coronary arteries and veins. We herein have reported the case of a 36-year-old male whose anterior interventricular vein drain...

The intrinsic viscosity of dendrimers in solution shows several anomalous behaviors that have hitherto not been explained within the existing theoretical frameworks of either Zimm or Rouse. Here we propose a simple two-zone model based on the radial segmental density profile of the dendrimers and combine a non-draining core with a free-draining outer region description, to arrive at a simple fo...

A 56-year-old male patient was admitted for catheter ablation of highly symptomatic paroxysmal atrial fibrillation. During the procedure, a rare anatomic variation with an interrupted inferior caval vein (ICV) branching suprarenal into an azygos venous continuation draining into the superior caval vein was detected. Using angiography, a continuation of the ICV leading into the liver, subdividin...

Abstract. A leading hypothesis for the mechanism of fast supraglacial lake drainages is that transient extensional stresses briefly allow crevassing in otherwise compressional ice flow regimes. Lake water can then hydrofracture a crevasse to base sheet, and river inputs maintain this connection as moulin. If future sheet models are accurately represent moulins, we must understand their formatio...

Purpose: We report the results of applying arterial spin labeling (ASL) to intracranial dural arteriovenous fistula (DAVF). Methods: Sixteen patients with angiographically confirmed DAVF underwent ASL on a clinical 1.5 T or 3 T MR system. ASL was performed by Q2TIPS (second version of quantitative imaging of perfusion by using a single subtraction MRI pulse sequence with thin-slice TI1 periodic...

The study of the variations in the superficial veins of head and neck and their draining pattern is very important due to the complexity in their developmental pattern. A total of 32 cadavers of both sexes were used for the study and the head and neck region were dissected carefully and photographed in the department of anatomy, Vinayaka Mission Kirupananda Variyar Medical College & Hospital, S...

A fuzzy control scheme is proposed for the system of filling and draining off water of the rubber dam(FDWRD) which is a typical nonlinear, multivariables, timevarying and strong coupling control system base on traditional PID control or model-based control methods can not meet its constant flow sufficient drainage control requirements, during to it couldn‘t be established accurate mathematical ...

Tissue-resident dendritic cells, such as Langerhans cells (LC), normally carry Ags from tissues to lymph nodes to induce immunity to tissue Ags. In this study, we report that LC are reduced in the skin-draining lymph nodes of MRL-Fas(lpr/lpr) and MRL-Fas(+/+) mice that develop T cell-mediated autoimmune skin inflammation as compared with MHC-matched healthy strains. This deficiency of LC in ski...
