Molecular genetic analysis of zooplankton has been slowed by the usual practice of preservation and storage of samples in dilute formalin solutions, which are not always adequately buffered for pH. We report here the determination of DNA sequences for Meganyctiphanes norvegica (Crustacea, Euphausiacea) preserved and stored in buffered formalin for up to 25(More)
We investigated the effects of the endothelin-1 (ET-1) receptor dual antagonist (Bosentan®) on the inflammatory cytokines and the chemoattractant molecules associated with breast cancer growth and the development of tumor infiltration in bone explants. Immunocompetent mice implanted with the murine mammary carcinoma 4T1 cells in a skin-fold chamber and(More)
Activator and inhibitor roles for the 88-kDa-secreted glycoprotein progranulin (PGRN) have been demonstrated in ovarian cancer cells. Here, we investigated the effects of PGRN in breast cancer migration. Testing MCF7, MDA-MB-453, and MDA-MB-231 human breast cancer cells and the MCF10A breast epithelial cell line, we demonstrate that LPA-induced PGRN(More)
BACKGROUND HIV-exposed uninfected infants have increased infection risk and mortality compared to HIV-unexposed infants. HIV-exposed infants may be at increased risk of invasive GBS disease due to reduced maternal antibody against GBS. METHODS We quantified antibodies that bind to the surface of whole Group B Streptococcus (GBS) of serotypes Ia, Ib, II,(More)
With corporate social responsibility (CSR) becoming more important to stakeholders and thus firms, understanding the relationship between CSR and corporate financial performance (CFP) is becoming more and more important. Although there is much research examining the general CSR-CFP relationship, there is very little, if any, research that investigates the(More)
The serum bactericidal assay is the correlate of protection for meningococcal disease but the use and comparison of functional immunological assays for the assessment of meningococcal vaccines is complicated by the sourcing of human complement. This is due to high levels of immunity in the population acquired through natural meningococcal carriage and means(More)
OBJECTIVES Placental antibody transfer is impaired in the context of HIV infection, which may render HIV-exposed, uninfected infants vulnerable to group B Streptococcus (GBS) disease. The GBS antibody response predominately consists of immunoglobulin G2 (IgG2) antibody. Thus we determined whether concentration and placental transfer of anti-GBS antibody(More)
A new generation multi-component vaccine, principally directed against serogroup B Neisseria meningitidis (4CMenB), has recently been developed. One of its components, identified through reverse vaccinology, is the neisserial heparin-binding antigen (NHBA) which is included in the formulation as a novel NHBA-GNA1030 fusion protein (NHBA-FP). We describe(More)

  • Applied research in mental retardation

This study addressed the disruptively loud voice volume of three adult mentally retarded subjects. A reduction in voice volume was affected through the use of the "tok-back" device, a crescent-shaped device made of lightweight plastic, which when fitted over the face covers the mouth and ears and provides feedback on sounds emitted. In Experiment 1, the(More)
Drug delivery systems offer the advantage of sustained targeted release with minimal side effect. In the present study, the therapeutic efficacy of a porous silica-calcium phosphate nanocomposite (SCPC) as a new delivery system for 5-Fluorouracil (5-FU) was evaluated in vitro and in vivo. In vitro studies showed that two formulations; SCPC50/5-FU and(More)
