The cellular molecular motors save energy
Discovery of the mechanism by which cell car engines inhibit its operation to save energy. Molecular motors, in most cell types, work to carry an internal load, as the organelles associated with energy production and transport of nutrients, including the entire cell. We have now discovered how these molecular motors fall into a way of [...]
Bacteria and disease transmission routes that originate
The nature, severity and development of any infection caused by bacteria, are characteristic of each species. Bacteria: This is called single-celled organism to any class, the genus has morphological varieties and their components can be spherical (cocci), elongated (bacilli), spiral (spirochetes), or comma-shaped (vibrios). Disease that is vaccine-preventable: – Whooping cough: The causative agent is [...]
Biological agents that can be used as weapons
Biological warfare is a disguised method can affect enemy population. Biological weapons can be obtained and spread easily. Biological agents are applied either in liquid or solid, are supplied to food or drink, are vaporized to be inhaled or contaminate by direct contact. – Tularemia as a biological weapon: Francisella tularensis is a bacterium that [...]
The Ecosophy: ecology and ethics to learn from the Earth
The Ecosophy is a way of living in harmony with the land they inhabit. An interdisciplinary science which teaches us to recognize, respect and care for our “home”. The Ecosophy is a stream of environmentalism but that goes beyond the anthropocentric position of the environmental movement as it incorporates a spiritual dimension and global. This [...]
A chimeric protein mutants against pathogens
Novartis Siena drew fHBP the protein that incorporates three different antigenic variants that can stimulate the immune system against various pathogens. Some scientists at Novartis Vaccines, Siena, in collaboration with the University of Florence have identified a chimeric protein useful for the design of new vaccines. FHBP protein (Factor H Binding Protein) was identified by [...]
Nanotechnology in neurology
Thanks to the nanotube drug carrier an international team was able to release the correct amount of medicine to repair damaged areas of the brain affected by stroke. The Institute of Neurosciences of the National Research Council of Pisa (In-CNR) in collaboration with University College London and University of Florence has conducted research to test [...]
Combats oxidative stress damage to DNA
A U.S. team found that oxidative stress induces increased synthesis of protein SIRT6 able to repair the rupture of double-stranded DNA. Were published in the journal Science the results of a survey dall”Universita of Rochester (USA) and has made the role of oxidative stress in a cell. During normal activities of the cell are made [...]
