cellular space of the brain, constitutes an ideal sample to evaluate the biochemical activity of the brain and, therefore, of the changes in the same that take place in dementia. It presents, however, the inconvenience of extracting by lumbar puncture, an invasive method, although it presents few complications (1-2). The alteration of these biomarkers in cerebrospinal fluid (CSF) has been associated in numerous studies at an increased rate of progress to EA in patients with mild cognitive impairment and correlates with loss of evidence evidence by magnetic resonance in regions of the medial temporal lobe typicallyAffected by the EA as the hypothalamus and the enterorrinal cortex, before the dementia...

cell or an organism to change its characteristics, cutting in the precise place in which the modification is to be made and extracting a sequence; or, inserting a different one in its place. Despite the great controversy that brings to the speaking of this issue, the genetic edition can improve our quality of life and is exciting, but it does not lack risks or ethical implications. Next, there will. Also, when embryos are modified, unnecessarily, they may suffer damage and then be reflected in their offspring or even designing babies to our liking implies that genetic edition generates controversies in society. Although experiments can be continued, of course not in humans, so that the treatments are...

cellular- that share fundamental characteristics in common, these allow them to be considered as "living" entities: they use an energy source to remain alive and reproduce. For example, a marine grass uses light energy to perform photosynthesis. They are formed by a series of units, - more or less independent - locked by membranes, known as cells. They have hereditary genetic information encoded in the genes that the organism uses to continuously renew its organs (for example the skin) and that also responds to the conditions of the immediate environment. They have the power of replication, such as viruses or bacteria. They are the product of evolution and each new set of organisms...

cell wall, controls their permeability It is important for the distension of cells and fulfills osmotic functions. Depending on CA absorption, it makes a passive process means it does not need energy. CA translocation helps to handle xilematic flow It presents deficiencies in crops, when the absorption capacity is greater than the requirements of plants, since it is not always due to lack of ground, in situations we have the accelerated growth of flowering, fruiting. The solution for this is to apply quelates Sodium cycle He was obtained in a state of purity for the first time in 1807. It is soft of silver color very abundant in nature being in the sea salt. Sodium is present in large quantities...

cell phones. The problem with this is that we alienate ourselves completely from what happens around us because we are very focused on the cell phone screen, thus avoiding spontaneous conversations at the table and that special moment of sharing all together as a family together a richDinner. For me it is also quite worrying the fact that most of today's children have immediate access to electronic devices and many times without their parents' supervision. Worse, that there are young children obsessed with social networks, virtual games, even with "chat". This somehow has to negatively affect the family, either by the fact that future electronic devices are being formed. Possible solutions...

Therefore, the task as a society is to fight to protect the family, and promote an environment of respect, values, education and love of our children;A family that is linked in all life...

cells would develop more. I hope that cloned frogs had sexual maturity and then mate two sexually mature clones, I achieve that donor nuclei could redirect development. This type of experiment was accepted by the scientific community, however, there were doubts about whether the core of the host ovulo was really implanted. This doubt remained as such from 1958 to 2002, although Gurdon tried to demonstrate that the nucleus was inserted. Marshall W. Nirenberg and Johann H. Matthaei were the first scientists to finally describe the complete genetic code. In 1961 they published a study where they used a cell free system where artificial mRNA was dealt with to synthesize proteins. The first RNM that was...

cells in a single operation, as opposed to its predecessor that only allowed reading a single cell by operation by operation. This technology was largely popular for its application in digital photography where it revolutionized the way of storing information. After currently arriving at the Flash Memoirs, they are integrated into USB Memoirs and SSD technology. Introduction The scope of this report is located in the computer science, to be more concrete in the field of hardware and information storage systems. It is an issue on which there are numerous works and analysis either developed by companies that market these components or by research entities such as universities, for this reason it is...
