The expression of the major glycoprotein, gp7l , of mu mineleukemia virus was studied on the surfaces of a variety of normal munine cell lines with a monospecific rabbit anti serum raised against purified Friend mumine leukemia virus gp7l . Using viable cell membrane immunofluorescence, most established and early passage normal muminecell lines were significantly reactive with the antiserum, ir...

background: hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of echinococcus granulosus. diagnosis of hydatidosis is still an unresolved problem. serological tests using crude antigens for diagnosis of e. granulosus are sensi-tive, however their specificity are not satisfactory. therefore, who recommended spe-cific serological methods using specific antigens,...

Abstract. Heavy rainfall events causing floods and flash are examined in the context of solar wind coupling to magnetosphere–ionosphere–atmosphere system. The superposed epoch (SPE) analyses variables have shown tendency severe weather follow arrivals high-speed streams from coronal holes. Precipitation data sets based on rain gauge satellite sensor measurements used examine relationship betwee...

Recently, we described the identification of novel streptococcal superantigens (SAgs) by mining the Streptococcus pyogenes M1 genome database at Oklahoma University. Here, we report the cloning, expression, and functional analysis of streptococcal pyrogenic exotoxin (SPE)-J and another novel SAg (SPE-I). SPE-I is most closely related to SPE-H and staphylococcal enterotoxin I, whereas SPE-J is m...

Immature spermatids from Caenorhabditis elegans are stimulated by an external activation signal to reorganize their membranes and cytoskeleton to form crawling spermatozoa. This rapid maturation, termed spermiogenesis, occurs without any new gene expression. To better understand this signal transduction pathway, we isolated suppressors of a mutation in the spe-27 gene, which is part of the path...

Background: Anti-HLA-antibodies are known to affect the allograft survival in transplant recipient patients. Objective: The aim of this study was to evaluate the association between anti-HLA antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (DBMI). Methods: Between June 2006 and May 2007, forty living unrelated donor kidney tra...

Estrogens and estrogen metabolites have important functions in cardiovascular and other physiology, yet the patterns of estrogen synthesis, metabolism, and the individual plasma profile of estrogens and estrogen metabolites during human pregnancy as well as in preeclampsia remain undetermined. We performed liquid chromatography mass spectrometry on plasma samples from normotensive pregnant wome...

The objective of this study was to evaluated the photoprotective effects of porcine placenta extract (PPE) on ultraviolet B (UVB)-induced oxidative stress in human keratinocytes (HaCaT) to evaluate its functional activities as a skin food ingredient. PPE prepared by subcritical water extraction was termed SPE, and subsequently digested by enzymes to prepare E-SPE. Increased intracellular reacti...

Biodegradable polyamines have long been studied as potential recombinant viral gene vectors. Spermine (SPE) is an endogenous tetra-amine with excellent biocompatibility yet poor gene condensation capacity. We have previously synthesized a polyspermine based on SPE and poly(ethylene glycol) (PEG) diacrylate (SPE-alt-PEG) for enhanced transfection performance, but the synthesized SPE-alt-PEG stil...
