The Death and Rebirth of a Party System, Peru 1978-2001

This article evaluates structural, institutional, and actor-centered explanations of the collapse of the Peruvian party system around 1990 and its surprising partial recovery in 2001. It begins by describing the changes in the dependent variable, the emergence, collapse, and partial resurrection of the 1980s Peruvian party system. The next section examines the argument that the large size and rapid growth of the informal sector undermined the party system and led to its collapse. The author shows that the evidence does not support this argument. The article then examines changes in the electoral system. The author demonstrates that, contrary to theoretical expectations, the changes in the electoral system do not correlate with the observed changes in the party system. The final section shows that performance failure by political elites, including corruption in government, was more important than social cleavages or electoral institutions in the collapse and partial recovery of the party system.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Fine-mapping studies distinguish genetic risks for childhood- and adult-onset asthma in the HLA region

Background: Genome-wide association studies of asthma have revealed robust associations with variation across the human leukocyte antigen (HLA) complex with independent associations in the HLA class I and class II regions for both childhood-onset asthma (COA) and adult-onset asthma (AOA). However, the specific variants and genes contributing to risk are unknown. Methods: We used Bayesian approaches to perform genetic fine-mapping for COA and AOA (n=9432 and 21,556, respectively; n=318,167 shared controls) in White British individuals from the UK Biobank and to perform expression quantitative trait locus (eQTL) fine-mapping in immune (lymphoblastoid cell lines, n=398; peripheral blood mononuclear cells, n=132) and airway (nasal epithelial cells, n=188) cells from ethnically diverse individuals. We also examined putatively causal protein coding variation from protein crystal structures and conducted replication studies in independent multi-ethnic cohorts from the UK Biobank (COA n=1686; AOA n=3666; controls n=56,063). Results: Genetic fine-mapping revealed both shared and distinct causal variation between COA and AOA in the class I region but only distinct causal variation in the class II region. Both gene expression levels and amino acid variation contributed to risk. Our results from eQTL fine-mapping and amino acid visualization suggested that the HLA-DQA1*03:01 allele and variation associated with expression of the nonclassical HLA-DQA2 and HLA-DQB2 genes accounted entirely for the most significant association with AOA in GWAS. Our studies also suggested a potentially prominent role for HLA-C protein coding variation in the class I region in COA. We replicated putatively causal variant associations in a multi-ethnic cohort. Conclusions: We highlight roles for both gene expression and protein coding variation in asthma risk and identified putatively causal variation and genes in the HLA region. A convergence of genomic, transcriptional, and protein coding evidence implicates the HLA-DQA2 and HLA-DQB2 genes and HLA-DQA1*03:01 allele in AOA.</p

High level expression of bioactive recombinant human growth hormone in the milk of a cloned transgenic cow

Transgenic farm animals have been proposed as an alternative to current bioreactors for large scale production of biopharmaceuticals. However, the efficiency of both methods in the production of the same protein has not yet been established. Here we report the production of recombinant human growth hormone (hGH) in the milk of a cloned transgenic cow at levels of up to 5 g l(-1). The hormone is identical to that currently produced by expression in E. coli. In addition, the hematological and somatometric parameters of the cloned transgenic cow are within the normal range for the breed and it is fertile and capable of producing normal offspring. These results demonstrate that transgenic cattle can be used as a cost-effective alternative for the production of this hormone.Fil: Salamone, Daniel Felipe. Universidad de Buenos Aires.
