This paper presents the application of active contour or snake for the segmentation of masses on breast ultrasound images and the characterization of the segmented masses as malignant or benign. Initially, the balloon snake is chosen to segment the masses. Comparison on the masses areas segmented by the balloon snake is done against the areas traced by radiologist. Experimental result shows tha...

Snake venom toxins are responsible for causing severe pathology and toxicity following envenomation including necrosis, apoptosis, neurotoxicity, myotoxicity, cardiotoxicity, profuse hemorrhage, and disruption of blood homeostasis. Clinically, snake venom toxins therefore represent a significant hazard to snakebite victims which underscores the need to produce more efficient anti-venom. Some sn...

We design interpolation snakes (or I-Snakes ) for border detection in ultrasound images. We argue that interpolation snakes are better suited for ultrasound than other snakes because the control points are on the curve. This allows for arclength parameterization of the snake, and for spatial hard constraints by fixing one or more control points on the spline. Moreover, built into the snake ener...

Venom detection is crucial for confirmation of envenomation and snake type in snake-bite patients. Enzyme immunoassay (EIA) is used to detect venom, but antivenom in samples prevents venom detection. We aimed to detect snake venom in post-antivenom samples after dissociating venom-antivenom complexes with glycine-HCl (pH 2.2) and heating for 30 min at 950 °C. Serum samples underwent dissociatio...

A close-form B-Snake model using statistics information for 2D objects segmentation is presented in this paper. We called it Dynamic B-Snake Model (DBM). It is able to model the features of the object in training set and guide the B-Snake in the deforming procedure. Compared to other deformable models, the DBM maintains the smoothness of curve while still remain compact representation. Moreover...

UNLABELLED Recent advances in proteomics enable deep profiling of the compositional details of snake venoms for improved understanding on envenomation pathophysiology and immunological neutralization. In this study, the venom of Australian tiger snake (Notechis scutatus) was trypsin-digested in solution and subjected to nano-ESI-LCMS/MS. Applying a relative quantitative proteomic approach, the ...

Here we develop an argument in support of sequencing a garter snake (Thamnophis sirtalis) genome, and outline a plan to accomplish this. This snake is a common, widespread, nonvenomous North American species that has served as a model for diverse studies in evolutionary biology, physiology, genomics, behavior and coevolution. The anole lizard is currently the only genome sequence available for ...

A snake crawling on horizontal surfaces between two parallel walls exhibits a unique wave-like shape, which is different from the normal shape of a snake crawling without constraints. We propose that this intriguing system is analogous to a buckled beam under two lateral constraints. A new theoretical model of beam buckling, which is verified by numerical simulation, is firstly developed to acc...

Introduction In 2010, there were 4,796 snake bite exposures reported to Poison Centers nationwide (1). Health care providers frequently request help from poison centers regarding snake envenomations due to the unpredictability and complexity of prognosis and treatment. The Missouri Poison Center (MoPC) maintains a surveillance database keeping track of every phone call received. ESSENCE, a synd...

objective(s): snake venoms contain complex mixture of proteins with biological activities. some of these proteins affect blood coagulation and platelet function in different ways. snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. in the present study, purification of anticoagulation factor from veno...
