The pathogenesis of the floppy valve syndrome is not fully solved. An almost invariable histological finding is the great accumulation of mucinous material in the valve leaflets and constitutes the basis of the valvular theory of the syndrome. The presence of a mucinous layer in normal valves-- the zona spongiosa--is not well recognised. To establish the normal range of the extent of this zone,...

in the current iris recognition systems, noise removing step is only used to detect noisy parts of the iris region and features extracted from there will be excluded in matching step. whereas depending on the filter structure used in feature extraction, the noisy parts may influence relevant features. to the best of our knowledge, the effect of noise factors on feature extraction has not been c...

OBJECTIVE Given the demonstrated effectiveness of medical treatment together with the eminent acceptance of the laparoscopic approach, the indications of surgery in the treatment of gastroesophageal reflux disease (GERD) are currently subject to continuous controversy. To participate in this debate, we have the following work hypothesis: "The results of the 360 masculine short and floppy laparo...

with an increasing emphasis on security, automated personal identification based on biometrics has been receiving extensive attention. iris recognition, as an emerging biometric recognition approach, is becoming a very active topic in both research and practical applications. in general, a typical iris recognition system includes iris imaging, iris liveness detection, and recognition. this rese...

PURPOSE To report the diagnosis and management of a patient with chronic ophthalmic topical anesthetic abuse and floppy eyelid syndrome. METHODS We describe the case of a 47-year-old man suffering from persistent bilateral ocular irritation and chronic corneal erosions. RESULTS The patient was hospitalized in our ophthalmology department and underwent thorough ophthalmic, systemic, and psyc...

Objective: given the demonstrated effectiveness of medical treatment together with the eminent acceptance of the laparoscopic approach, the indications of surgery in the treatment of gastroesophageal reflux disease (GERD) are currently subject to continuous controversy. To participate in this debate, we have the following work hypothesis: “The results of the 360o short and floppy laparoscopic f...

iris recognition is one of the most reliable methods for identification. in general, itconsists of image acquisition, iris segmentation, feature extraction and matching. among them, iris segmentation has an important role on the performance of any iris recognition system. eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. in this pa...

Introduction: Infant botulism is a relatively uncommon but potentially life threatening cause of a septic appearing or lethargic infant. Case Report: A 6­week­old male infant presented to the emergency department with a history of poor feeding and fever for several days. His parents reported that he had been “more sleepy than usual” and had a weak cry. He had not passed any stool for five days....
