Completed the first clinical trial for HIV vaccine
During phase, trial of the vaccine was successful in 90% of volunteers with AIDS, using the MVA-B virus containing HIV genes 4. Spanish researchers have completed the first clinical trial of a new vaccine against HIV. This vaccine offers great hope to eradicate this scourge forever. The team led by Dr. Mariano Esteban, a researcher [...]
A new anti-cancer gene
A young Italian team discovered the anti-tumor activity of the mutated gene MTND1 able to block the tumor blood vessels of tumors. Thanks to a study funded by AIRC (Italian Association for Cancer Research), a team of young Italian University of Bologna was able to find a gene that can block tumor growth. The mutant [...]
Bioplastics: Plastics made from renewable raw materials
Biodegradable plastics based on starch, sugar and cellulose have a growing ecological significance. 4 percent of the world’s annual oil production for the production of conventional plastics are used. Because this fossil fuel only limited available, and also during its combustion pollutants are released, the search for environmentally friendly alternatives made from renewable resources is [...]
Therapy against Alzheimer’s on the track
Alzheimer’s disease has not yet been effectively treated. Researchers from Rostock and Leipzig are successfully treated at the track. The hope for an effective Alzheimer’s therapy is nourished by the end of summer 2011. On 1 September 2011 gave scientists from Rostock and Leipzig, announced the results of their research. Researchers at the University of [...]
A snail is capable of photosynthesis
A sea slug is capable of photosynthesis by chloroplasts of algae from which it feeds. The photosynthesis is a process by which carbohydrates are produced and oxygen from water, carbon dioxide and sunlight. This function is performed in the chloroplasts of plants. Why do plants have chloroplasts? Currently it is believed that in the distant [...]
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 [...]
Peculiarities of the enzymes
All living things have chemicals that are involved in multiple cellular processes, some of these substances are enzymes. The catalysts of biological reactions are known by the name of enzymes, biological catalysts or biocatalysts, formerly called ferments. Enzymes are proteinaceous compounds are produced intra-and extracellularly and are essential for all metabolic processes of living organisms. [...]
