Nucleosomes get peeled and rewrapped
arly endosomes may help to create their own short-range tracks, according to a report from Stéphane Gasman, Yannis Kalaidzidis, and Marino Zerial (Max Planck Institute, Dresden, Germany). The results also suggest parallels between membrane trafficking, signaling, and regulation of the cytoskeleton. Trafficking of early endosomes requires the small GTPase RhoD. Zerial’s group identified the firs...
متن کاملProtein names precisely peeled off free text
MOTIVATION Automatically identifying protein names from the scientific literature is a pre-requisite for the increasing demand in data-mining this wealth of information. Existing approaches are based on dictionaries, rules and machine-learning. Here, we introduced a novel system that combines a pre-processing dictionary- and rule-based filtering step with several separately trained support vect...
متن کاملNucleosomes, transcription, and probability
Speaking of current measurements on single ion channel molecules, David Colquhoun wrote in 2006, "Individual molecules behave randomly, so suddenly we had to learn how to deal with stochastic processes." Here I describe theoretical efforts to understand recent experimental observations on the chromatin structure of single gene molecules, a molecular biologist's path toward probabilistic theories.
متن کاملLinking numbers and nucleosomes.
In considering supercoils formed by closed double-stranded molecules of DNA certain mathematical concepts, such as the linking number and the twist, are needed. The meaning of these for a closed ribbon is explained and also that of the writhing number of a closed curve. Some simple examples are given, some of which may be relevant to the structure of chromatin.

The purpose of this study was to investigate the effect of implementing the suggestion system on reducing the silent behavior of employees of the Petroleum Industry Research Institute (RIPI). This research is consumed an applied research; based on the research method, quasi-experimental a pre-test and post-test with a group staff before and after the implementation of a comprehensive. To perfor...
