A major challenge in systems neuroscience is to perform precise molecular genetic analyses of a single neuronal population in the context of the complex mammalian brain. Existing technologies for profiling cell type–specific gene expression are largely limited to immature or morphologically identifiable neurons. In this study, we developed a simple method using fluorescent activated cell sortin...

begun to provide a comprehensive picture of the hereditary information required for various forms of life. But what do all the genes so identified do to warrant their existence? In the unicellular yeast Saccharomyces cerevisiae, for example, all predicted genes have been deleted,and the resulting strains subjected to a battery of analyses. These genome-wide studies have shown that only about 19...

Changes in the Structure of Earnings During the Polish Transition We document changes in the structure of earnings during the economic transition in Poland. We find that inequality in labor earnings increased substantially from 1988 to 1996. A common view is that the reallocation of workers from a public sector with a compressed wage distribution, to a private sector with much higher wage inequ...

background: fasciolosis in livestock is a crucial concern in the globe, mainly due to its impact on human health. the aim of this study was to determine the rate of infection with fasciola gigantica (cobbold, 1855) larvae in the field-collected snails of lymnaea auricularia (linnaeus, 1785) from northwestern iran using a molecular approach. methods : a total of 6,759 pond snails were collected ...

PHI-443 (N'-[2-(2-thiophene)ethyl]-N'-[2-(5-bromopyridyl)] thiourea) is a rationally designed novel thiophene thiourea nonnucleoside reverse transcriptase inhibitor (NNRTI) with potent anti-HIV activity against the wild-type and drug-resistant primary clinical human immunodeficiency virus (HIV-1) isolates. This study examined the potential utility of PHI-443 as a nonspermicidal microbicide for ...

In this paper, we investigate M(2,) in case 2. is a normal lattice of subsets of X and we extend the results to 1, 2’2-lattices of subsets of X such that 2.1 C 2-2 and 2,1 separates 2.2. We define the outer measures /P and #" which prove very useful in proving some of the above results.

THE Tractato utilissimo circa la conservatione de la sanitade is described by D. P. Lockwood1 as 'one of the earliest Italian medical works in the vernacular' to which 'Ugo now owes his chief distinction in the history of medicine'. No manuscript of this treatise exists, it was not mentioned in the Latin Vita Ugonis written about 1441 by his eldest son Soccino Benzi (1406-79), also a physician,...
