The human parasitic trematode Schistosoma mansoni has a complex life cycle that includes the freshwater snail Biomphalaria glabrata as intermediate host. Within each stage, the parasite synthesizes a wide array of glycoconjugates, exhibiting, in part, unique carbohydrate structures. In addition, the parasite expresses definitive host-like sugar epitopes, such as Lewis X determinants, supporting...

BACKGROUND The objective was to explore the relationship between left ventricular ejection fraction (LVEF) assessed during hospitalization for acute myocardial infarction (MI) and later health-related quality of life (HRQoL). METHODS We used multivariable linear regression to assess the relationship between LVEF and HRQoL in 256 MI patients who responded to the Kansas City Cardiomyopathy Ques...

Semi-steppe rangelands are a complex, highly dynamic and often multi-layered mosaic of grassland, shrubland, and intermediate communities. A few recent studies have explicitly or implicitly developed synthetic hypotheses about how interactive effects of human made disturbances initiate dynamic changes in plant community composition to cause a shifting mosaic of vegetation pattern across the lan...

BACKGROUND Vaccination against influenza is considered the most important public health intervention to prevent unnecessary hospitalizations and premature deaths related to influenza in the elderly, though there are significant inequities among global influenza vaccine resources, capacities, and policies. The objective of this study was to assess the social determinants of health preventing adu...

In the past twenty years or so, the study of the determinants of child survival in low-income countries has been based on demographic conceptual frameworks. The most widely known has been the Mosley and Chen framework [1]. In that framework, the key concept was a set of proximate determinants, or intermediate variables, that directly influence the risk of morbidity and mortality. It assumes tha...

background & aim: thecurrent population of the world is seven billion, and developing countries account for its 97%. approximately 210 million pregnancies annually occur worldwide and 75-80 million of them are reported to be unintended. multiple factors can contribute to unintended pregnancy, which need to be assessed to design interventions reducing the incidence of unintended pregnancies.this...

maternal mortality refers to the death of a woman who dies during pregnancy or within six weeks after delivery. a number of factors contribute to the high maternal mortality ratio around the globe, particularly, in underdeveloped countries. pakistan has the highest mortality ratio (260 per 100,000 live births) in the region and is one of the developing countries which have committed to decrease...

a case control study was performed in three districts in hormozgan province in 2001 to assess how different determinants affect on malaria morbidity. it assume that results will help the decision makers in all levels of national development program. a total of 384 febrile patients with positive peripheral blood smear were selected as case group, and 753 people with negative peripheral blood sme...
