A preliminary subnational statistical analysis of violence against Christians in contemporary India, this article suggests that whereas the data provide very little support for simple, demographic explanations of this violence, they do more robustly support theories emphasizing the relative status of ethnic and religious minorities (vis-à-vis majorities) and the perception, among Hindus, that Christians (and other minorities) represent a threat to their numerical, political and economic strength. 相似文献

The transient receptor potential vanilloid 1 ion channel is responsible for the perception of high temperatures and low extracellular pH, and it is also involved in the response to some pungent compounds. Importantly, it is also associated with the perception of pain and noxious stimuli. Here, we attempt to discern the molecular organization and location of the N and C termini of the transient receptor potential vanilloid 1 ion channel by measuring FRET between genetically attached enhanced yellow and cyan fluorescent protein to the N or C terminus of the channel protein, expressed in transfected HEK 293 cells or Xenopus laevis oocytes. The static measurements of the domain organization were mapped into an available cryo-electron microscopy density of the channel with good agreement. These measurements also provide novel insights into the organization of terminal domains and their proximity to the plasma membrane. 相似文献

Herein, we report the synthesis and structure–activity relationship studies of new analogs of boceprevir 1 and telaprevir 2. Introduction of azetidine and spiroazetidines as a P2 substituent that replaced the pyrrolidine moiety of 1 and 2 led to the discovery of a potent hepatitis C protease inhibitor 37c (EC50 = 0.8 μM). 相似文献

The parasphenoid is located in the cranium of many vertebrates. When present, it is always an unpaired, dermal bone. While most basal vertebrates have a parasphenoid, most placental mammals lack this element and have an unpaired, dermal vomer in a similar position (i.e. associated with the same bones) and with a similar function. As such, the parasphenoid and the vomer were considered homologous by some early twentieth century researchers. However, others questioned this homology based on comparisons between mammals and reptiles. Here we investigate the parasphenoid bone across the major vertebrate lineages (amphibians, reptiles, mammals and teleosts) including both developmental and evolutionary aspects, which until now have not been considered together. We find that within all the major vertebrate lineages there are organisms that possess a parasphenoid and a vomer, while the parasphenoid is absent within caecilians and most placental mammals. Based on our assessment and Patterson's conjunction tests, we conclude that the non‐mammalian parasphenoid and the vomer in mammals cannot be considered homologous. Additionally, the parasphenoid is likely homologous between sarcopterygian and actinopterygian lineages. This research attempts to resolve the issue of the parasphenoid homology and highlights where gaps in our knowledge are still present. 相似文献

In nature, ribosomally synthesized proteins can contain at least 22 different amino acids: the 20 common amino acids as well as selenocysteine and pyrrolysine. Each of these amino acids is inserted into proteins codon-specifically via an aminoacyl-transfer RNA (aa-tRNA). In most cases, these aa-tRNAs are biosynthesized directly by a set of highly specific and accurate aminoacyl-tRNA synthetases (aaRSs). However, in some cases aaRSs with relaxed or novel substrate specificities cooperate with other enzymes to generate specific canonical and non-canonical aminoacyl-tRNAs. 相似文献
