The phenotype of fibrodyspiasia ossiflcans progressiva (FOP) includes two defining features: congenital malformation of the great toes and progressive heterotopic ossification in characteristic ...anatomic patterns. Additional common features include proximal medial tibial osteochondromas, orthotopic fusions of the posterior elements of the cervical spine, broad short femoral necks, and conductive hearing loss. The FOP phenotype supports that the primary molecular pathology involves the bone morphogenetic protein (BMP)-signaling pathway directly or a BMP-interacting pathway.
Differential protection of transformer using FPGA Gupta, Piyush; Khandelwal, Mayank; Sharma, Rishi ...

This paper presents a technique of implementing Differential relays based on Field Programmable Gate Arrays (FPGA), which can be used for the protection of transformers, distribution lines, large ...industrial motors and many equipment's of the power system. Due to its re-configurability, it gives an idea to implement many types of relays on the single FPGA board. In case of microprocessor based relays many peripheral devices are required making the operation slower; but in the case of FPGA, the same can be realized with less number of peripherals, thus making the operation faster. The proposed differential relay gives satisfactory results when simulated on the Xilinx FPGA, thus providing the best solution among existing technologies.
Abstract
BACKGROUND:
Intraprocedural rupture is a dangerous complication of endovascular treatment. Small ruptured anterior communicating artery (ACoA) aneurysms and microaneurysms present a ...challenge for both surgical and endovascular therapies to achieve obliteration. An understanding of the complication rates of treating ruptured ACoA microaneurysms may help guide therapeutic options.
OBJECTIVE:
To report the largest cohort of ACoA microaneurysms treated with endovascular therapy over the course of the past 10 years.
METHODS:
We performed a retrospective review of 347 ACoA aneurysms treated in 347 patients at Cleveland Clinic and Emory University over a 10-year period. Patient demographics, aneurysmal rupture, size, use of balloon remodeling, patient outcomes, intraprocedural rupture, and rerupture were reviewed.
RESULTS:
Rupture rates were examined by size for all patients and subgroups and dichotomized to evaluate for size ranges associated with increased rupture rates. The highest risk of rupture was noted in aneurysms less than 4 mm. Of 347 aneurysms, 74 (21%) were less than 4 mm. The intraprocedural rupture rate was 5% (18/347) for ACoA aneurysms of any size. There was an intraprocedural rupture rate of 2.9% (8/273) among ACoA aneurysms greater than 4 mm compared with 13.5% (10/74) in less than 4-mm aneurysms. Procedural rupture was a statistically significant predictor of modified Rankin score after adjusting for Hunt and Hess grades (HH).
CONCLUSION:
ACoA aneurysms less than 4 mm have a 5-fold higher incidence of intraprocedural rerupture during coil embolization. Outcome is negatively affected by intraprocedural rerupture after adjusting for HH grade.
Meta Search Engine Based on Prioritizor Chaurasia, B. K.; Gupta, S. K.; Soni, R.

Conference Proceeding
Meta search engine searches information using multiple independent search engines. World wide web has been developed to a distributed information space nearly more than 800 million working stations ...and several billion pages, which brings the people great trouble in finding needed information although huge amount of information available on webs. The focus of this paper is to design and implementation of a meta search engine. The work is to develop prioritizor based and profile assisted meta search engine for merging the results extracted from two or more search engines. The results and analysis show that the improved the search quality to the specific specialty.
Abstract Background Inflammatory pseudotumor is a nonneoplastic process of unknown etiology most frequently involving the lungs and orbits. Primary intracranial inflammatory pseudotumors are ...exceptionally rare. The authors report a rare case of clinoidal inflammatory pseudotumor mimicking a medial sphenoid wing meningioma. Case Description A 24-year-old woman presented with visual diminution and proptosis in the left eye for one and a half years. Imaging revealed a medial sphenoid wing mass, which was surgically decompressed. Histopathology confirmed the diagnosis of inflammatory pseudotumor after which she was treated with steroids. The patient is doing well at 3 months' follow-up with resolution of proptosis and no further diminution of vision. Conclusion Inflammatory pseudotumors can mimic a malignant tumor both radiologically and clinically. The treatment options consist of surgery, high-dose steroids, irradiation, and chemotherapeutic agents with variable therapeutic response. Intracranial involvement due to inflammatory pseudotumor is exceptionally rare. The importance of recognizing and appropriately diagnosing this rare intracranial pathology lies in prognostication and avoidance of overzealous treatment.
