Bacterial Evolution: What Goes Around Comes Around
نویسندگان
چکیده
Over 3 billion years ago, cellular life began anaerobically. A new study now establishes a key link between oxidative stress and proliferation of wall-less bacteria known as L-forms. The finding provides insights into both the origin of life and the potential threat posed by pathogenic L-forms.

What goes around, comes around: John Gregory, MD, and the profession of medicine.
Each generation of physicians believes the problems they face are unique. History shows that very few situations are new to medicine. Some appear to have been around for centuries (medical institutions' "cherry-picking" of patients, third-party interference in medical care), while others have been around for millennia (competition among physicians, competition between physicians and nonphysicia...
متن کاملWhat Goes around Comes around-A Comparative Study of the Influence of Chemical Modifications on the Antimicrobial Properties of Small Cyclic Peptides
Tryptophan and arginine-rich cyclic hexapeptides of the type cyclo-RRRWFW combine high antibacterial activity with rapid cell killing kinetics, but show low toxicity in human cell lines. The peptides fulfil the structural requirements for membrane interaction such as high amphipathicity and cationic charge, but membrane permeabilisation, which is the most common mode of action of antimicrobial ...
متن کاملWhat Goes Around Comes Around : A Theory of Indirect Reciprocity in Networks by Maximilian Mihm
We consider strategic interaction on a network of heterogeneous long-term relationships. The bilateral relationships are independent of each other in terms of actions and realized payoffs, and we assume that information regarding outcomes is private to the two parties involved. In spite of this, the network can induce strategic interdependencies between relationships, which facilitate efficient...
متن کاملWhat Goes around Comes Around: the Impact of Personal Conflict Style on Work Conflict and Stress
Conflict styles are typically seen as a response to particular situations. By contrast, we argue that individual conflict styles may shape an employee's social environment , affecting the level of ongoing conflict and thus his or her experience of stress. Using data from a hospital-affiliated clinical department, we find that those who use a more integrative style experience lower levels of tas...
متن کاملWhat Goes Around Comes Around — Improving Linked Open Data through On-Demand Model Creation
We present a method for growing the amount of knowledge available on the Web using a hermeneutic method that involves background knowledge, Information Extraction techniques and validation through discourse and use of the extracted information. We exemplify this using Linked Data as background knowledge, automatic Model/Ontology creation for the IE part and a Semantic Browser for evaluation. Th...
