Some enterotoxigenic Escherichia coli (ETEC) produce a type II heat-labile enterotoxin (LT-II) that activates adenylate cyclase in susceptible cells but is not neutralized by antisera against cholera toxin or type I heat-labile enterotoxin (LT-I). LT-I variants encoded by plasmids in ETEC from humans and pigs have amino acid sequences that are ≥ 95% identical. In contrast, LT-II toxins are chro...

Lymphotoxin (LT) provides a critical signal for the genesis of lymph nodes (LN) in mice. Here we show that mice treated in utero with LT beta-R-Ig, which binds to the membrane LT alpha 1 beta 2 heterotrimer, lacked most LN, yet retained a set of mucosal surface draining LN. Since mice genetically deficient in LT alpha lack all LN, including the mucosal set, we hypothesize that a novel LT alpha-...

Introduction: In this paper, we study the design of space–time codes for frequency selective quasi-static fading channels with nonnegligible ISI. It has been shown by Tarokh et al. [1] that the achievable diversity of a space– time code designed for flat fading channel is not reduced if it is used in a frequency selective fading channel. However, a full diversity space-time code designed for fl...

The proportion of patients undergoing liver transplantation (LT) with renal insufficiency has significantly increased in the Model for End-Stage Liver Disease (MELD) era. This study was designed to determine the incidence and predictors of post-LT chronic renal failure (CRF) and its effect on patient survival in the MELD era. Outcomes of 221 adult LT recipients who had LT between February 2002 ...

The proportion of patients undergoing liver transplantation (LT), with concomitant renal dysfunction, markedly increased after allocation by the model for end-stage liver disease (MELD) score was introduced. We examined the incidence of subsequent post-LT end-stage renal disease (ESRD) before and after the policy was implemented. Data on all adult deceased donor LT recipients between April 27, ...

background: liver transplantation (lt) is now performed as a cure of numerous untreatable pediatric liver diseases. quality of life (qol) can be affected in pediatric patients with lt. many factors are responsible for lower scores of qol. this article aims to detail qol in liver recipients 6 months after lt in children. methods: qol assessed using child health quality-parent form 50 for parents...

Rats immunized with Escherichia coli heat-labile (LT) enterotoxin, either in the form of the holotoxin derived from a transformed K-12 strain or the polymyxin-release form obtained from human strains which produce LT toxin alone (LT+/ST- [ST is heat-stable toxin)] or together with ST toxin (LT+/ST+), were challenged with viable organisms of 10 different serotypes, 5 LT+/ST- and 5 LT+/ST+. The s...
