Neutron charge form factor at large
The neutron charge form factor is determined from an analysis of
the deuteron quadrupole form factor data. Recent calculations, based
on a variety of different model interactions and currents, indicate that the
contributions associated with the uncertain two-body operators of shorter range
are relatively small for , even at large momentum transfer . Hence,
can be extracted from at large without undue
systematic uncertainties from theory.Comment: 8 pages, 3 figure
A Case of Problematic Diffusion
Sex determination techniques have diffused rapidly in India, and are being used to detect female fetuses and subsequently to abort them. This technology has spread rapidly because it imparts knowledge that is of great value within the Indian context, and because it fits in neatly with the modernization dynamic within India, which itself has enmeshed with traditional patriarchal institutions to oppress Indian women. More research needs to be done on ways to stem the adoption of problematic innovations.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68396/2/10.1177_107554709401500301.pd
Genetic Associations and Differential mRNA Expression Levels of Host Genes Suggest a Viral Trigger for Endemic Pemphigus Foliaceus
The long search for the environmental trigger of the endemic pemphigus foliaceus (EPF,
fogo selvagem) has not yet resulted in any tangible findings. Here, we searched for genetic asso ciations and the differential expression of host genes involved in early viral infections and innate
antiviral defense. Genetic variants could alter the structure, expression sites, or levels of the gene
products, impacting their functions. By analyzing 3063 variants of 166 candidate genes in 227 EPF
patients and 194 controls, we found 12 variants within 11 genes associated with differential suscepti bility (p < 0.005) to EPF. The products of genes TRIM5, TPCN2, EIF4E, EIF4E3, NUP37, NUP50, NUP88,
TPR, USP15, IRF8, and JAK1 are involved in different mechanisms of viral control, for example, the
regulation of viral entry into the host cell or recognition of viral nucleic acids and proteins. Only two
of nine variants were also associated in an independent German cohort of sporadic PF (75 patients,
150 controls), aligning with our hypothesis that antiviral host genes play a major role in EPF due to a
specific virus–human interaction in the endemic region. Moreover, CCL5, P4HB, and APOBEC3G
mRNA levels were increased (p < 0.001) in CD4+ T lymphocytes of EPF patients. Because there is
limited or no evidence that these genes are involved in autoimmunity, their crucial role in antiviral responses and the associations that we observed support the hypothesis of a viral trigger for EPF,
presumably a still unnoticed flavivirus. This work opens new frontiers in searching for the trigger
of EPF, with the potential to advance translational research that aims for disease prevention and
treatment
