Genes controlling production of Shiga-like toxin type II (SLT-II) in Escherichia coli were cloned from the SLT-II-converting bacteriophage 933W and compared with the Shiga-like toxin type I (SLT-I) genes previously isolated and described from phage 933J. Subcloning analysis identified a region within the 4.9-kilobase EcoRI fragment of phage 933W that was associated with SLT-II production. Exper...

BACKGROUND The projected 6-year cost comparison of primary selective laser trabeculoplasty (SLT) versus primary medical therapy in the treatment of open-angle glaucoma for Ontario patients aged 65 years or more is presented. Costs are taken from the perspective of the Ontario Health Insurance Plan at a per-patient level. METHODS The cost of each medication was obtained from the 2003 Ontario D...

OBJECTIVES The current study team sought to understand smokeless tobacco (SLT) usage trends among youth, using nationally representative data collected as part of the Canadian Youth Smoking Survey (YSS) between 2004 and 2008. METHODS Descriptive analyses of SLT ever use among respondents in grades 6 to 9 were examined according to year of data collection (2008, n = 31,249; 2006, n = 34,050; a...

Hybrid Automatic-Repeat-Request (H-ARQ) Aided Systematic Luby Transform (SLT) Coded Modulation is proposed, where SLT codes are used both for correcting erroneous bits and for detecting as well as retransmitting erroneous Internet Protocol (IP) based packets. Erroneous IP packet detection is implemented using syndrome checking with the aid of the SLT codes’ Parity Check Matrix (PCM). Optimizing...

BACKGROUND Sulphidoleukotrienes (slt) are important mediators in allergic diseases that are synthesized after allergen-specific stimulation. OBJECTIVES The aim of this study is to determine in vitro slt production after allergen-specific (Dermatophagoides pteronyssinus) stimulus of peripheral blood leucocytes and to observe whether histamine release in whole blood with the same allergen corre...

The purpose of the study was to investigate the changes in the endothelial cell count and cell’s polymegathism and pleomorphism after selective laser trabeculoplasty (SLT) in open-angle glaucoma (OAG). SLT has been performed on 18 patients (22 eyes). Each patient underwent confocal microscopy 1 h prior to the laser surgery and then 1 h, 1 day, 1 week, and 1 month after SLT. The obtained microgr...

In this study, we determined the nucleotide sequence of the p gene contained within a 5-kb EcoRI restriction fragment cloned from Shiga-like toxin II (SLT-II)-converting phage 933W of Escherichia coli O157:H7 strain EDL933. The p gene was 702 bp long and had 95.3% sequence similarity to the p gene of phage lambda. Multiple hybridization patterns were obtained when genomic DNA fragments were hyb...

OBJECTIVE To investigate whether development of smokeless tobacco products (SLT) is intended to target current smokers. METHODS This study analysed internal tobacco industry documents to describe research related to the smokeless tobacco market. Relevant documents included those detailing the development and targeting of SLT products with a particular emphasis on moist snuff. RESULTS Cigare...

OBJECTIVE To summarize the experience with salvage liver transplantation (SLT) for patients with recurrent hepatocellular carcinoma (HCC) after primary hepatic resection in a single center. METHODS A total of 376 adult patients with HCC underwent orthotopic liver transplantation (OLT) at Organ Transplantation Center, the First Affiliated Hospital of Sun Yat-sen University, between 2004 and 20...
