The vascular depression (VD) hypothesis postulates that cerebrovascular disease may ‘‘predispose, precipitate, or perpetuate’’ a depressive syndrome in elderly patients. Clinical presentation of VD has been shown to differ to major depression in quantitative disability; however, as little research has been made toward qualitative phenomenological differences in the personality aspects of the sy...

FOR MORE THAN A CENTURY FOLLOWING the discovery of sphingolipids, biochemists viewed these ubiquitous phospholipids as pharmacologically silent structural elements of the cell membrane. After the identification of G protein-coupled receptors for sphingosine-1-phosphate (S1P) (1, 8, 10), researchers began to recognize the importance of sphingolipid-mediated cell signaling, and this recognition l...

On the Relevance of Exchange Rate Regimes for Stabilization Policy This paper assesses the relevance of the exchange rate regime for stabilization policy. This regime question cannot be dealt with independently of other institutions, in particular how fiscal policy is designed. We show that once fiscal policy is taken into account, the exchange rate regime is irrelevant. This is the case indepe...

An observer-based, standardized index of housing quality (structural quality, privacy, indoor climate, hazards, cleanliness/clutter, and children’s resources) is significantly related to psychological distress and a behavioral index of learned helplessness, which reflects an important component of human motivation. Independent of household income, thirdthrough fifth-grade children residing in p...

Purpose: Cytosolic phospholipase A2-a (cPLA2-a) provides intracellular arachidonic acid to supply both cyclooxygenase and lipoxygenase pathways.We aim to determine the expression and activation of cPLA2-a in prostate cancer cell lines and tissue and the effect of targeting cPLA2-a in vitro and in vivo. Experimental Design:The expression of cPLA2-a was determined in prostate cancer cells by reve...

The development of transgenic insect technology has the potential to combat a broad range of vector-borne diseases and insect pests. Current technologies involve transposable genetic elements such as piggyBac, Hermes, mariner-Mos1 and Minos. These have been used successfully to integrate transgenes into the genomes of numerous insect species, including Diptera, Lepidoptera, Coleoptera and Hymen...

This paper focuses on the factors which influence collaborative learning in distance education. Distance education has been around for many years and the use of collaborative learning techniques in distance education is becoming increasingly popular. Several studies have demonstrated the superiority of collaborative learning over traditional modes of learning and it has been identified as a pot...

Ocean Drilling Program (ODP) Leg 199, “The Paleogene Equatorial Transect” (Sites 1215 through 1222), was designed to study the evolution of the equatorial Pacific current and wind system as the Earth went from maximum Cenozoic warmth to initial Antarctic glaciations. The drilling program was primarily devoted to a transect along 56to 57-Ma crust, old enough to capture the Paleocene/ Eocene boun...
