BACKGROUND The pp-Whipple procedure requires extensive preparation. The conventional preparation technique is done with scissors for dissection and ligatures, and with clips and sutures for hemostasis. This procedure is very time-consuming and requires numerous changes of instruments. The LigaSure™ device allows dissection and hemostasis for preparation with one instrument. Up to now there has ...

Despite advances in equipment and imaging, new challenges have arisen as the face of the world population changes. The CDC estimates that more than one-third of U.S. adults, and nearly, 17% of youth in America are obese [2]. According to the national scoliosis foundation, 2–3% of the U.S. population is affected by scoliosis. Generalized edema in sick and hospitalized patients, degenerative disk...

The authors present a new numerical method for the Chebyshev approximation of minimum phase FIR digital filters. This method is based on solving a least squares (LS) problem iteratively. At each iteration, the desired response is transformed so as to have an equiripple magnitude error. This method makes it possible to design minimum phase FIR filters whose magnitude error is quasi-equiripple. U...

INTRODUCTION A bottleneck for high-throughput proteomic studies is image analysis. In conventional two-dimensional (2D) methodology, protein samples are separated on individual gels, stained, and quantified, followed by image comparison with computer-aided image analysis programs. Since different images are not always perfectly superimposable, image analysis is very time consuming. Fluorescent ...

Endovascular intervention of peripheral chronic total occlusion (CTO) is technically challenging and time consuming. Various techniques and devices are used to facilitate lesion crossing and improve the success rate of the procedure. However, these new devices are quite expensive and not readily available. We report 2 cases of peripheral CTO wherein the occlusions were successfully crossed by u...

Image registration is an efficient computational technique for diagnosis and diseases monitoring. Lungs airways diseases, such as chronic obstructive pulmonary disease (COPD) and asthma, require periodical checkups and past data comparison to estimate the patient condition. In this work, it is proposed an airways registration algorithm that is performed branch by branch. The branch registration...

Rationalisation of biomarkers using the conventional histopathological procedure is time consuming, laborious and pricey especially, when several markers are to be tested on various specimens. So, TMA is expected to surmount these substantial problems [3]. Tissue microarrays are produced by harvesting cylindrical tissue core...

normal 0 false false false en-us x-none ar-sa background: dry weight (dw) is an important concept related to patients undergoing hemodialysis. conventional method seems to be time consuming and operator dependent. bio impedance analysis (bia) is a new and simple method reported to be an accurate way for estimating dw. in this study, we aimed to compare the conventional estimation of dw with mea...

Establishment of rating curves are often required by the hydrologists for flow estimates in the streams, rivers etc. Measurement of discharge in a river is a time-consuming, expensive, and difficult process and the conventional approach of regression analysis of stage-discharge relation does not provide encouraging results especially during the floods. P

Chemoenzymatic peptide synthesis is the hydrolase-catalyzed stereoselective formation of peptide bonds. It is a clean and mild procedure, unlike conventional chemical synthesis, which involves complicated and laborious protection-deprotection procedures and harsh reaction conditions. The chemoenzymatic approach has been utilized for several decades because determining the optimal conditions for...
