Bacterial Border Fence
Bacteria lack many of the features that eukaryotic cells use to compartmentalize cytoplasm and membranes. In this issue, Schlimpert et al. describe a new mechanism of spatial confinment in the bacterium Caulobacter crescentus that prevents the exchange of soluble and membrane proteins between the stalk and cell body.
متن کاملAnalysis of Musculoskeletal Injuries Sustained in Falls From the United States-Mexico Border Fence.
Injuries sustained by unauthorized individuals who jump or fall from the United States-Mexico border fence are frequently treated by trauma centers in border states. The authors investigated patterns of musculoskeletal injury occurring in these individuals to improve emergency department assessment and to identify strategies to prevent future injuries. A retrospective chart review was performed...
متن کاملJumping over the fence
The nuclear envelope forms a cocoon that surrounds the cellular genome keeping it out of harm's way and can be utilized by the cell as a means of functionally regulating chromatin structure and gene expression. At the same time, this double-layered membrane system constitutes a formidable obstacle to the unimpeded flow of genetic information between the genome and the rest of the cell. The nucl...
متن کاملFence protection progress
Twenty years ago, it was about saving the rhino, but now it may end up being about mitigating the effects of climate change. Although the reasons for continuing to build an electric fence around the Aberdare mountains in Kenya have changed, conservationists and local farmers agree that the fence is a good thing to have. Back in 1988, the charity Rhino Ark started raising funds for a stretch of ...
متن کاملClostridium difficile toxins facilitate bacterial colonization by modulating the fence and gate function of colonic epithelium.
The contribution of Clostridium difficile toxin A and B (TcdA and TcdB) to cellular intoxication has been studied extensively, but their impact on bacterial colonization remains unclear. By setting up 2- and 3-dimensional in vitro models of polarized gut epithelium, we investigated how C. difficile infection is affected by host cell polarity and whether TcdA and TcdB contribute to such events. ...
