We have witnessed successes of production grids and various grid applications in last decade. Motivated by previous and current grid initiatives and raising science community demands for computing resources, project CRO-GRID was initiated. CRO-GRID is a national multi-project whose goals are introduction of grid and cluster technologies to science community and industry and development of distr...

Temperate bacteriophages possess a genetic switch which regulates the lytic and lysogenic cycle. The genomes of the temperate telomere phages N15, PY54, and ϕKO2 harbor a primary immunity region (immB) comprising genes for the prophage repressor (cI or cB), the lytic repressor (cro) and a putative antiterminator (q). The roles of these products are thought to be similar to those of the lambda p...

Endocarditis is a rare but serious manifestation of Listeria monocytogenes (LM). However, the optimal treatment strategy for LM endocarditis has yet to be established. Current antibiotic strategies for listeriosis include penicillin G or ampicillin (AMP) monotherapy, or AMP + gentamicin combination therapy which is often favored for endocarditis. The primary objective of our investigation was t...

UNLABELLED The type I signal peptidase of Staphylococcus aureus, SpsB, is an attractive antibacterial target because it is essential for viability and extracellularly accessible. We synthesized compound 103, a novel arylomycin-derived inhibitor of SpsB with significant potency against various clinical S. aureus strains (MIC of ~1 µg/ml). The predominant clinical strain USA300 developed spontane...

BACKGROUND To assess prospectively the incidence of chronic and neuropathic pain in patients undergoing anteroaxillary thoracotomy with postoperative epidural analgesia or controlled-release oxycodone pain regimen. METHODS 77 patients who underwent anteroaxillary thoracotomy were enrolled in our observational study. 40 patients received postoperatively a standardized oral analgesic protocol w...

the study aimed to investigate the protective effects of crocin (cro) against streptozotocin (stz)-induced oxidative damage in rat striatum. animals were randomly divided into four groups (five each). group 1 (sham) were treated with normal saline (2 ml/kg, p.o.). group 2 (stz-lesioned or lesion) were injected with icv-stz (3 mg/kg bilaterally, on day 1 and 3) and treated with normal saline (2 ...

Clustering is an intensive research for some years because of its multifaceted applications, such as biology, information retrieval, medicine, business and so on. The expectation maximization (EM) is a kind of algorithm framework in clustering methods, one of the ten algorithms of machine learning. Traditionally, optimization of objective function has been the standard approach in EM. Hence, re...

Andreev reflection at a Pb/CrO(2) point contact has been used to determine the spin polarization of single-crystal CrO(2) films made by chemical vapor deposition. The spin polarization is found to be 0.96 +/- 0.01, which confirms that CrO(2) is a half-metallic ferromagnet, as theoretically predicted.

The Texas Commission on Environmental Quality (TCEQ) conducted a chronic inhalation noncancer toxicity assessment for crotonaldehyde (CRO). Since there were limited toxicity data for CRO, a reference value (ReV) was derived using a relative potency factor (RPF) approach with acrolein as the index chemical. Both CRO and acrolein are α,β-unsaturated carbonyls and share common steps in their mode ...

Materials and Methods: This randomized, double-blind, placebo-controlled, prospective clinical study received institutional review board approval. After written informed consent was obtained, 210 patients with liver cancer were randomized into three groups of 70 patients. Group 1 received 20 mg of CRO, group 2 received 10 mg of CRO, and group 3 received a placebo at 1 hour before transarterial ...
