We exemplify an optimisation criteria for divide-and-conquer algorithms with a technique called generic competitive graph search. The technique is then applied to solve two problems arising from biocomputing, so-called Common Connected Components and Cograph Sandwich. The first problem can be defined as follows: given two graphs on the same set of n vertices, find the coarsest partition of the ...

Electron crystallography is an important method for determining the structure of membrane proteins. In this paper, we show the impact of a carbon sandwich preparation on the preservation of crystalline sample quality, using characteristic examples of two-dimensional (2D) crystals from gastric H(+),K(+)-ATPase and their analyzed images. Compared with the ordinary single carbon support film prepa...

INTRODUCTION Lumbar hernia account for less than 2% of al abdominal hernias, been the Grynfelt-Lesshaft's hernia (GLH) more frequent than the others. With approximately 300 cases published in the literature, the general surgeon may have the chance of treat it ones in their professional life. CASE REPORT A 42-years old male with human immunodeficiency virus and Diabetes Mellitus presented to t...

BACKGROUND Wandering spleen is a rare clinical condition caused by incomplete fusion of the 4 primary splenic ligaments, allowing the spleen to be mobile within the abdomen, predisposing to splenic torsion along the vascular pedicle leading to splenomegaly and infarction, often diagnosed in an emergency setting. METHODS The wandering spleen diagnosis was achieved by ultrasound in our case. We...

BACKGROUND The sandwich double-patch technique was adopted as an alternative method for reconstruction of the left ventricle after excision of postinfarction dysfunctional myocardium to solve technical problems due to the thick edges of the ventricular wall. METHODS Over a 5-year period, 12 of 21 patients with postinfarction antero-apical left ventricular aneurysm had thick wall edges after w...
