Like Putting Mayo on a Bialy

  In a discourse analysis with regards to stance and social indexicality, representational language or “TV language” from the series The Marvelous Mrs. Maisel illuminates several functions of Yiddish loanwords as variables: stancetakers’ disproportionate stance acts, inter-generational usage of person/type terms to evoke prejudice, and younger speakers’ appropriation of conventional usages. It is suggested that because Yiddish terms often contain conventional associations with usages or users, situated meanings arise from a basis of conventionality. The following situated meanings of Yiddish loanwords and their functionality add to existing third wave variation theory, as variables construct speakers’ desired personae

Perceptions of fecal microbiota transplantation for Clostridium difficile infection: factors that predict acceptance.

BackgroundDespite the effectiveness of fecal microbiota transplantation (FMT) for treating recurrent Clostridium difficile (C. difficile) infection, some patients are reluctant to accept this therapy. Our study examined attitudes towards FMT and factors that contribute to patients' acceptance of this treatment.MethodsWe distributed patient surveys at a Veterans Affairs hospital, a public hospital, and an academic faculty practice. Multivariable logistic regression was performed, adjusting for factors associated with FMT acceptance on univariate analysis and prior experience with C. difficile infection.ResultsOf 267 patients, only 12% knew of FMT prior to the survey, but 77% would undergo the procedure if medically indicated. On multivariable analysis, those with children and with college degrees or higher were more likely to agree to FMT (odds ratio [OR] 2.11, 95% confidence interval [CI] 1.02-4.35; OR 2.27, 95% CI 1.11-4.60 respectively). Sixty-five respondents (71%) chose colonoscopy as the preferred vehicle for FMT, while nasogastric tube was least preferred. Disease transmission was the most common concern (30%, n=242), and FMT success rate was the least selected concern (9.1%).ConclusionsMost patients in a diverse sample of gastroenterology clinics had no prior knowledge of FMT, but were receptive to the procedure. Having children and higher education levels were predictors for FMT acceptance. Our findings suggest that barriers to FMT utilization may be overcome with counseling about safety concerns. More data on the risk of transmitting diseases or clinical characteristics, such as obesity, through FMT are needed and will be important for the acceptance of this procedure

The Role of Dopamine in the Collective Regulation of Foraging in Harvester Ants.

Colonies of the red harvester ant (Pogonomyrmex barbatus) differ in how they regulate collective foraging activity in response to changes in humidity. We used transcriptomic, physiological, and pharmacological experiments to investigate the molecular basis of this ecologically important variation in collective behavior among colonies. RNA sequencing of forager brain tissue showed an association between colony foraging activity and differential expression of transcripts related to biogenic amine and neurohormonal metabolism and signaling. In field experiments, pharmacological increases in forager brain dopamine titer caused significant increases in foraging activity. Colonies that were naturally most sensitive to humidity were significantly more responsive to the stimulatory effect of exogenous dopamine. In addition, forager brain tissue significantly varied among colonies in biogenic amine content. Neurophysiological variation among colonies associated with individual forager sensitivity to humidity may reflect the heritable molecular variation on which natural selection acts to shape the collective regulation of foraging

Duffy antigen receptor for chemokines (Darc) polymorphism regulates circulating concentrations of monocyte chemoattractant protein-1 and other inflammatory mediators

To identify the genetic basis of circulating concentrations of monocyte chemoattractant protein-1 (MCP-1), we conducted genome-wide association analyses for MCP-1 in 3 independent cohorts (n = 9598). The strongest association was for serum MCP-1 with a nonsynonymous polymorphism, rs12075 (Asp42Gly) in DARC, the gene for Duffy antigen receptor for chemokines, a known vascular reservoir of proinflammatory cytokines (minor allele frequency, 45.6%; P < 1.0 * 10−323). This association was supported by family-based genetic linkage at a locus encompassing the DARC gene (genome-wide P = 8.0 * 10−13). Asp42Gly accounted for approximately 20% of the variability in serum MCP-1 concentrations and also was associated with serum concentrations of interleukin-8 and RANTES. While exploring a lack of association between this polymorphism and EDTA plasma MCP-1 concentrations (P = .82), we determined that both clotting and exogenous heparan sulfate (unfractionated heparin) released substantial amounts of MCP-1 from Darc. Quantitative immunoflow cytometry failed to identify meaningful Asp42Gly-associated differences in Darc expression, suggesting that a functional change is responsible for the differential cytokine binding. We conclude that Asp42Gly is a major regulator of erythrocyte Darc-mediated cytokine binding and thereby the circulating concentrations of several proinflammatory cytokines. We have also identified for the first time 2 mechanisms for the release of reservoir chemokines with possible clinical implications
