The DHS Wealth Index originally was constructed from existing data on household assets, services, and amenities in order to tabulate health, population, nutrition, education, and other indicators according to economic status. The Wealth Index has proved to be one of the most useful background characteristics available from the Demographic and Health Survey (DHS) data. It is now standard in DHS ...

Pyrrolizidine alkaloids are preformed plant defense compounds with sporadic phylogenetic distribution. They are thought to have evolved in response to the selective pressure of herbivory. The first pathway-specific intermediate of these alkaloids is the rare polyamine homospermidine, which is synthesized by homospermidine synthase (HSS). The HSS gene from Senecio vernalis was cloned and shown t...

The ever-increasing demand for heating in different sectors, along with more preventative regulations on greenhouse emissions, has forced different countries to seek new alternatives to heat buildings such as district heating system (DHS). Although rudiments of DHSs can be observed over the centuries, it was not widely implemented until last two decades when the DHS became a strategy to design ...

Users’ participation in the design process may change the overall goals of the design. Also, the context in which a prototype is tested might play a critical role in the design process. This paper presents how the contexts of use and a dialogue among users and designers shaped the DHS system. The DHS is a Web-based system that allows users to attach a commentary to certain Web documents. This s...

Species of several unrelated families within the angiosperms are able to constitutively produce pyrrolizidine alkaloids as a defense against herbivores. In pyrrolizidine alkaloid (PA) biosynthesis, homospermidine synthase (HSS) catalyzes the first specific step. HSS was recruited during angiosperm evolution from deoxyhypusine synthase (DHS), an enzyme involved in the posttranslational activatio...

OBJECTIVE To analyze the in vitro mechanical strength of the DHS-AF(®). METHODS We evaluated the in vitro resistance of a sliding bolt modified by the addition of a connector system, DHS-AF(®). RESULTS The changes performed by the authors allow the exchange by the surgeon of the sliding bolt without the need to remove the plate and disassemble the entire device to reposition it properly. We...

In this paper, we first show how the Demographic and Health Surveys (DHS) can be integrated with other data sources to expand the types of variables available for analysis of population and health outcomes. Second, we demonstrate one particular example of such integration by modelling the social, physical, and built environment determinants of health outcomes at the district level in Ghana, Mal...

BACKGROUND In countries with limited vital registration, adult mortality is frequently estimated using siblings' survival histories (SSHs) collected during Demographic and Health Surveys (DHS). These data are affected by reporting errors. We developed a new SSH questionnaire, the siblings' survival calendar (SSC). It incorporates supplementary interviewing techniques to limit omissions of sibli...

Dropped head syndrome (DHS) is a relatively rare condition, with a broad differential diagnosis. This deformity has significant implications on the health and quality of life of affected individuals. While surgery seems to be an obvious therapeutic option, there is a paucity of information on surgical intervention with no clear consensus on an optimal approach or timing. We present a case of DH...

INTRODUCTION The objective of this study was to determine if a synthetic bone substitute would provide results similar to bone from osteoporotic femoral heads during in vitro testing with orthopaedic implants. If the synthetic material could produce results similar to those of the osteoporotic bone, it could reduce or eliminate the need for testing of implants on bone. METHODS Pushout studies...
