Our objectives were to compare the prevalence of sexually transmitted infections (STIs) in 103 women undergoing induced legal abortion (LA) and in 101 women with confirmed, recent illegal abortion (IA), in Maputo, Mozambique. For the purpose of this study, LA was considered the abortion provided in the Maputo Central Hospital with the approval of the Ministry of Health, and IA the one not provided

The permeability of skin to nanoparticles of titanium dioxide (TiO2) used in sunscreens as a reflector of the UV wavelengths of sunlight, was examined using nuclear microscopy techniques. Special attention was given to the permeation characteristics of these nanoparticles across the outer layers of skin, the stratum corneum, in healthy and psoriatic skin condition. Aspects that may influence the i

While the use of radio technology for wireless data communications has increased rapidly, the wide variety of radio interfaces being used has made interference investigations hard to perform. With that in mind, we present a novel approach for analyzing packet radio communications, applicable to interfering heterogeneous networks, which leads to tractable analytical expressions. The core of the app

In vitro studies of the carotenoid peridinin, which is the primary pigment from the peridinin chlorophyll-a protein (PCP) light harvesting complex, showed a strong dependence on the lifetime of the peridinin lowest singlet excited state on solvent polarity. This dependence was attributed to the presence of an intramolecular charge transfer (ICT) state in the peridinin excited state manifold. The I

Background: The use of global gene expression profiling to identify sets of genes with similar expression patterns is rapidly becoming a widespread approach for understanding biological processes. A logical and systematic approach to study co-expressed genes is to analyze their promoter sequences to identify transcription factors that may be involved in establishing specific profiles and that may

A concept based on the Peroxidase-chip (P-chip), antibody co-immobilization, competitive and enzyme-channeling principle was exploited to develop an integrated flow-through amperometric biosensor for detection of environmental pollutants such as s-triazine herbicides. In this concept, recombinant peroxidase is immobilized on the gold electrode (P-chip) in such a way that direct electron transfer i

The present article is part of a larger project investigating the various types of linguistic change that affected and might affect the word class traditionally known under the label of interjection. The results of our research, as outlined here, concern the inter-linguistic mobility of units, i.e., borrowings, which in the source language can be (but not necessarily) interjections, and which are

The theory of subpicosecond Frenkel exciton dynamics in molecular systems is reviewed with emphasis on a stepwise imp loved description of the coupling to intra- and intermolecular vibrations. After introducing the concept of multiexciton states the motion of electronic Frenkel excitons as they appear in light harvesting antennae of photosynthetic organisms is discussed. The description is based o

Photoemission studies and layer resolved Korringa-Kohn-Rostoker (KKR) multiple scattering calculations are used to find the assignment of the surface core-level shifts to the top layers of the Be(10 (1) over bar0) surface. Striking similarities between experimental and calculated data make it possible to assign the largest shift to layer two, the second largest shift to layers three and four, and

1. Extracellular adenosine triphosphate (ATP) is mitogenic for vascular smooth muscle cells (VSMC) and stimulates several events that are important for cell proliferation: DNA synthesis, protein synthesis, increase of cell number, immediate early genes, cell-cycle progression, and tyrosine phosphorylation. 2. Receptor characterization indicates mitogenic effects of both P2U and P2Y receptors. The

Since many of the data offered in his text, and many of his conclusions, give the indication of agreeing with what is more or less loosely termed process psychology, I would like to try my own hand at drawing a theoretical sketch of how images can be conceptualized within a theory of perception. The sketch agrees basically with what Quill, inspired by Whitehead, takes to be the requirements of a t

The objective was to explore the meaning of the phenomenon of problem solving in midwifery when the midwife is faced with a critical situation in the absence of an obstetrician or any physician. A qualitative method was used and critical incidents from delivery wards and/or antenatal clinics in the south of Sweden were narrated by midwives and transcribed verbatim. The interwievs were then analyse
