There is a simple example for Max Cut that shows our analysis is nearly tight. Consider G = C5, the cycle on 5 nodes {0, 1, 2, 3, 4}, with all edge weights being 1. The optimum solution is 4 with an optimum cut being, say, S = {1, 3} with δ(S) = {(0, 1), (1, 2), (2, 3), (3, 4)} (we can do no better because C5 is not bipartite). Next we define a feasible SDP solution with value greater than 4. L...

Previous reports have established that line 1, a spontaneous BALB/c lung carcinoma, expresses a M, 180,000 tumor-associ ated surface antigen (TSP-180). In this study, using a monoclonal antibody and flow cytometry to quantify cell surface TSP-180 expression, we found that essentially all cells in a tissue cultureadapted line 1 population express TSP-180, but that the amount of TSP-180 expressed...

OBJECTIVES This study investigated whether the novel St. Thomas' Hospital polarizing cardioplegic solution (STH-POL) with esmolol/adenosine/magnesium offers improved myocardial protection by reducing demands for high-energy phosphates during cardiac arrest compared to the depolarizing St. Thomas' Hospital cardioplegic solution No 2 (STH-2). METHODS Twenty anaesthetised pigs on tepid cardiopu...

BACKGROUND The surfactant poloxamer 188 (P188) has been shown to improve survival following hemorrhage. This study used P188 as a small volume resuscitation product in a sedated, sexually mature, male miniature swine severe hemorrhage model for potential improvement in rate and time of survival. METHODS Fourteen swine were anesthetized, catheterized for hemorrhage and resuscitation and allowe...

Previous reports have established that line 1, a spontaneous BALB/c lung carcinoma, expresses a Mr 180,000 tumor-associated surface antigen (TSP-180). In this study, using a monoclonal antibody and flow cytometry to quantify cell surface TSP-180 expression, we found that essentially all cells in a tissue culture-adapted line 1 population express TSP-180, but that the amount of TSP-180 expressed...

BACKGROUND Five accelerometer-derived methods of identifying nonwear and wear time were compared with a self-report criterion in adults ≥ 56 years of age. METHODS Two hundred participants who reported wearing an Actical™ activity monitor for four to seven consecutive days and provided complete daily log sheet data (i.e., the criterion) were included. Four variables were obtained from log shee...

this study investigated the concentration/time dependent effects of nanosilver colloid on the motionparameters of the ejaculated ram spermatozoa in vitro. after incubation of sperm samples for 30, 60, 120 and 180 min in the presence of nanosilver colloid (0, 0.001, 0.01, 0.1, 1 and 10 ppm), the motion parameters were evaluated by computer assisted sperm analysis. there was a significant (p

In 2001, at the TRIGA reactor of the University of Pavia (Italy), a patient suffering from diffuse liver metastases from an adenocarcinoma of the sigmoid was successfully treated by boron neutron capture therapy (BNCT). The procedure involved boron infusion prior to hepatectomy, irradiation of the explanted liver at the thermal column of the reactor, and subsequent reimplantation. A complete re...

Preparation of Cell Lysates For immunoblot analyses of NER factors from human fibroblast cells, the cells in 60-mm dishes were washed twice with phosphate-buffered saline and lysed in situ with 0.25 ml of ice-cold NP lysis buffer [25 mM Tris-HCl (pH 8.0), 1 mM EDTA, 10% glycerol, 1% Nonidet P-40, 10 mM N-ethylmaleimide, 0.25 mM phenylmethylsulfonyl fluoride (PMSF), a protease inhibitor cocktail...
