the lpsa gene, a late acting gene in the biosynthetic pathway of ergovaline, a suspected causative agent for fescue toxicosis in cattle, has been cloned from neotyphodium lolii, an endophytic fungus of lolium perenne. in this study, a similar gene was detected in several strains of endophytic neotyphodium spp. isolated from grass hosts endogenous to iran using direct and nested-pcr assays. exce...

The lpsA gene, a late acting gene in the biosynthetic pathway of ergovaline, a suspected causative agent for fescue toxicosis in cattle, has been cloned from Neotyphodium lolii, an endophytic fungus of Lolium perenne. In this study, a similar gene was detected in several strains of endophytic Neotyphodium spp. isolated from grass hosts endogenous to Iran using direct and nested-PCR assays. Exce...

The objective of this paper is to summarize the latest techniques, applications, methodologies, use of different software, and development of codes, in the field of Living Probabilistic Safety Assessment (LPSA) and Risk Monitoring (RM). The paper consists of three parts, in first part definitions, history, aims, uses of LPSA, and a new detailed model for LPSA have been explain. In second part b...

A Pasteurella haemolytica A1 gene involved in the biosynthesis of a moiety on the core of the lipopolysaccharide molecule has been cloned and characterized. Escherichia coli clones which carry this gene showed an alteration of its lipopolysaccharide migration profile on tricine SDS-PAGE and exhibited resistance to the core-specific phage U3. In addition, lipopolysaccharide extracted from the E....

An accurate understanding of the anatomy of the levator palpebrae superioris aponeurosis (LPSA) is critical for successful blepharoplasty of aponeurotic ptosis. We investigated the macroscopic and microscopic anatomy of the LPSA.This prospective live gross anatomy study enrolled 200 adult Chinese patients with bilateral mild ptosis undergoing elective blepharoplasty. Full-thick eyelid tissues a...

The Block Sorting Lossless Data Compression Algorithm (BWT) described by Burrows and Wheeler has received considerable attention. Its compression rates are simliar to context-based methods, such as PPM, but at execution speeds closer to Ziv–Lempel techniques. This paper describes the Lexical Permutation Sorting Algorithm (LPSA), its theoretical basis and delineates its relationship to BWT. In p...

The Block Sorting Lossless Data Compression Algorithm (BSLDCA) described by Burrows and Wheeler 3] has received considerable attention. It achieves as good compression rates as context-based methods, such as PPM, but at execution speeds closer to Ziv-Lempel techniques 5]. This paper, describes the Lexical Permutation Sorting Algorithm (LPSA), its theoretical basis, and delineates its relationsh...

West Nile virus (WNV) is known to affect captive populations of alligators and, in some instances, cause significant mortalities. Alligators have been shown to amplify the virus, serve as a reservoir host, and even represent a source of infection for humans. This study describes a cutaneous manifestation of WNV in captive-reared American alligators (Alligator mississippiensis), previously descr...

Pretreatment of macrophages with low-dose endotoxin (LPSp) profoundly alters cytokine release in response to subsequent LPSa activation. These qualitative and quantitative alterations in cytokine release have been termed macrophage reprogramming. Macrophage activation by LPS is thought to occur via a mechanism involving an early protein tyrosine kinase (PTK) phosphorylation step. PTK inhibition...
