Quorum sensing concept shed new lights on the collective regenerative behavior through study of hair plucking
Scientists know injuries sometime induce regeneration sometime not. Scientists search for factors that can promote regeneration. Usually, regeneration process is studied by analyzing the regenerative behavior of one organ unit. However, this may not be sufficient to
A factor that regulates the expression of HIV genes
Proteins are the machinery of life. Nearly everything in a cell is manufactured by, regulated by or composed of proteins, which are encoded in genes. When a cell needs a particular protein, the DNA encoding the protein
Evolution of diverse and bizarre stag beetle weapons
Stag beetles evolved an impressive diversity of weapons because the shape and size of the armature hardly influence the cost of flying. Computer simulations of flying stag beetles have shown that the energy cost is solely determined
Back to the future – looking at COPD with new eyes
Chronic obstructive pulmonary disease (COPD) is a broad term for diffuse lung disease caused by chronic inflammation of the airways. Patients with COPD become increasingly short of breath and often start to feel as if they are
Hemoglobin diseases and their identification
Red blood cells use hemoglobin to carry oxygen from the lungs to the body and to carry carbon dioxide from the body back to the lungs in order to keep all cells alive. Hemoglobin is a big
Guanine-nucleotide exchange factor that promotes loss of polygonal cell shape
Actin cytoskeleton dynamics determines cell shape and movement. Fibroblasts or epithelial cells, for instance, adhere and spread onto planar surfaces adopting an elongated polygonal shape. Underneath the cytoplasmic membrane, local activation of small GTPase enzymes of the
Laboratory mice – ready-made for animal studies?
Laboratory animals, most of them mice, are bred and used to model human diseases. On one hand this offers great possibilities for science, one the other hand this topic is controversially debated. Beside ethical concerns, the major
A new take on walking exercise to stimulate adaptations in the nervous system
Exercise causes adaptations that ultimately make performance of physical activity easier. One way the body adapts to exercise is by re-organization of the central nervous system (CNS). Some neural connections may be strengthened, while others may be
Climate-friendly wastewater management
A major part of the energy loss from new energy-efficient buildings is the emission of warm wastewater to the sewers. This leads to increased interest for heat recovery from domestic wastewater, which may contain up to 800
Novel recombinant JEV vaccine
Japanese Encephalitis (JE) is a viral disease, which infects humans and animals. The disease is caused by a mosquito-borne flavivirus named Japanese Encephalitis Virus (JEV). The disease is endemic in Asian countries but with rapid globalization and
Bibliometric analysis of scientific output on influenza in Mexico, 2000-2012
During the spring of 2009, H1N1 influenza became the first pandemic of the 21st century. In the last years, bibliometrics studies have proliferated seeking to provide data on world research. There are no bibliometric studies in Mexico
