Abstract Background Georgia has a significant risk of ongoing HIV and HCV outbreak. Within this context, harm reduction aims to reduce associated with drug use through community activities, such as peer recruitment involvement. The aim study was identify differences between known hidden populations, attest the utility peer-driven intervention across multiple years in recruiting high-risk, vulne...

The global food supply system is facing serious new challenges from economic and related crises and climate change, which directly affect the nutritional well-being of the poor by reducing their access to nutritious food. To cope, vulnerable populations prioritize consumption of calorie-rich but nutrient-poor food. Consequently, dietary quality and eventually quantity decline, increasing micron...

network scale-up is an indirect method for estimating the size of hidden, hard-to-count or high risk populations. social network size estimation is the first step in this method. the present study was conducted with the purpose of estimating the social network size of the tehran province residents and its determinants.maximum likelihood estimation was applied to estimate people's network sizes ...

TO THE EDITOR: Currently, nearly one in every 13 adults abuses alcohol or is alcohol dependent. In addition, several million adults also engage in risky drinking behavior that could lead to alcohol-related problems. However, only a small proportion of the people with alcohol problems ever seek and engage in treatment (1). A national survey in the United States (2) found that only 16% of those w...

Intraorganism genetic stability is assumed in most organisms. However, here we show for the first time intraorganism genetic heterogeneity in natural populations of marine sponges. A total of 36 different multilocus genotypes (MLGs) were detected in 13 individuals of Scopalina lophyropoda sampled at 4 distant points within each sponge. All genotypes (showing a mosaic distribution), were transmi...

The movement of people into the Americas has brought different populations into contact, and contemporary American genomes are the product of a range of complex admixture events. Here we apply a haplotype-based ancestry identification approach to a large set of genome-wide SNP data from a variety of American, European and African populations to determine the contributions of different ancestral...

A data mining case study is presented illustrating exploration for hidden inpatient subpopulations. Some of the major characteristics of data mining and their relation to business goals are reviewed. Six subpopulations are tentatively identified. Two subpopulations correspond to mental illness and alcohol/drug abuse. Four other subpopulations reflect medical and surgical diseases, segregated al...

The amount of hidden genetic variability within electromorphs in finite populations is studied by using the infinite site model and stepwise mutation model simultaneously. A formula is developed for the bivariate probability generating function for the number of codon differences and the number of electromorph state differences between two randomly chosen cistrons. Using this formula, the distr...

Mendelian traits are considered to be at the lower end of the complexity spectrum of heritable phenotypes. However, more than a century after the rediscovery of Mendel's law, the global landscape of monogenic variants, as well as their effects and inheritance patterns within natural populations, is still not well understood. Using the yeast Saccharomyces cerevisiae, we performed a species-wide ...
