The parasitic protozoa Leishmania major produces a peroxidase (L. major peroxidase; LmP) that exhibits activities characteristic of both yeast cytochrome c peroxidase (CCP) and plant cytosolic ascorbate peroxidase (APX). One common feature is a key Trp residue, Trp(208) in LmP and Trp(191) in CCP, that is situated adjacent to the proximal His heme ligand in CCP, APX, and LmP. In CCP, Trp(191) f...

Epstein-Barr virus (EBV) is a human herpesvirus associated with a number of malignancies. EBV establishes a latent infection in human B cells in vitro, and infected lymphoblastoid cells proliferate indefinitely as a result of virus activation of cellular signalling pathways. Latently infected cells express a viral oncoprotein called the latent membrane protein-1 (LMP-1). LMP-1 signals both prol...

Although the Muslim world is sometimes depicted as a homogeneous civilization lacking democracy and gender equality, Muslim countries show tremendous economic, political and cultural variation. In this paper, this variation is used to gain insight into the determinants of women’s labor market participation (LMP) in the Muslim world. We use data on 45 Muslim countries and apply SEM models to det...

The Epstein-Barr virus latent membrane protein 1 (LMP-1) is essential for virus-induced B cell immortalization and can protect B lymphoma cell lines from apoptosis signals in vitro via induction of cellular Bcl-2 expression. However, we have reported that high-level expression of LMP-1 in epithelial cells (RHEK-1 cells) itself induces apoptosis. This apoptotic event occurs in the absence of det...

This study focused on the anti-oxidative and collagenase- and elastase inhibition effects of low molecular weight peptides (LMP) from commercial Jeju horse leg bone hydrolysates (JHLB) on pancreatin, via enzymatic hydrolysis. Cell viability of dermal fibroblasts exposed to UVB radiation upon treatment with LMP from JHLB was evaluated. Determination of the antioxidant activity of various concent...

Aims—To study the distribution of Epstein-Barr virus (EBV) variants containing mutations in the latent membrane protein 1 (LMP-1) oncogene and promoter in EBV associated Hodgkin’s disease and infectious mononucleosis compared with previous findings in asymptomatic EBV carriers. Methods—Sequence analysis of the EBV LMP-1 promoter and gene in isolates from Danish patients with Hodgkin’s disease (...

LMP-1, an Epstein-Barr viral (EBV) latency protein, is considered a viral oncogene because of its ability to transform rodent fibroblasts in vivo and render them tumorigenic in nude mice. In human B cells, EBV LMP-1 induces DNA synthesis and abrogates apoptosis. LMP-1 is expressed in EBV-transformed lymphoblastoid cell lines, nasopharyngeal carcinoma (NPC), a subset of Hodgkin's disease (HD), a...

Aims-To analyse the latent membrane protein-1 (LMP-1) gene in a series of patients with Epstein-Barr virus (EBV) positive LMP expressing ordinary and HIV associated Hodgkin's disease to detect possible genetic alterations and particularly the existence of deletions near the 3' end of the gene.Methods-Expression of the EBV LMP-1 was assessed using immunohistochemistry in 186 cases of Hodgkin's d...

BACKGROUND The requirement for ultrasound to establish gestational age among women seeking abortion can be a barrier to access. Last menstrual period dating without clinical examination should be a reasonable alternative among selected women, and if reliable, can be task-shared with non-clinicians. This study determines the accuracy of gestational age estimation using last menstrual period (LMP...
