Programmed cell death

that exist in around us.They essentially feast on the cells, breaking the human’s building blocks down for their own use. But if the living and the dead are composed of the same fundamental materials, what prevents us, the living, from being devoured by the horde of hungry pathogens? The answer lies in the body’s immune system. The story starts with the bacteria entering the human body and starting to multiply. In this process, the human cells are damaged and assimilated to help the…

Mitochondria are filamentous organelles of all aerobic cells of higher animals and plants and also certain microorganism like protozoa. Studies show that that mitochondria are the direct descendants of a bacterial endosymbiont that became established at an early stage in a nucleus-containing host cell (Gray et al., 1999). Mitochondria are surrounded by a double-membrane system, consisting of inner and outer mitochondrial membranes separated by an intermembrane space. (Cooper, 2000). It has the…

theory in our life because it explains why we all live as aging organisms. There are many different types of theories, two that we learned in class are programmed and error theories. Programmed theories define how aging is all about evolution, it is not biology. If aging was about biology we all would live forever and not die. The system aging and death are in your body when you are born. However, aging is related to biology for example, how biology can increase one body’s susceptibility…

from Beyond Battens Foundation to enhance number of trials. Stem cell treatments in which stem cells lines are taken from patients and their families are currently being used in the effort to find a cure. [7,9,11,13] Families with an affected individual are often faced with all the decision regarding treatment. As the disease worsens some chose to withdraw or withhold treatment or request that their child is euthanised. Before death, individuals are completely bed bound and unable to…

In Aristotle’s view, everything in this world can be categorized. Living beings include plants and animal. The plant has nutritive soul and the animal process both nutritive soul and perceptive soul. If we discuss animal further, we can divide animal into rational animal, which is human, and non-rational animal. The essential feature of “being an animal” is perception. From the Aristotle Introductory Reading: “413b2: What makes something an animal is primarily perception.” Perception is…

Genetic Engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. With this new, rapidly growing, technology we are now able to do things that we once thought were impossible. In Ethics and the New Genetics, the Dalai Lama addresses problems that we need to consider as we continue to explore this microscopic world that we have…

within a cell, they can be expressed in response to external stimuli. This external stimuli can be sub lethal heat shock (SLHS) hence the name heat shock proteins (Baneyx, F. 2008), this stimulus causes more of the proteins to be produced (Pugsley, A. 1989). In addition to being expressed due to SLHS they can also be expressed in response to amino acid analogs, heavy metals…

In the case of a missing limb, the scientists would take stem cells from the patient and us it for the base of the new limb. If Humans mastered cloning then they could use that technology and the patient’s stem cells to construct a new arm, leg, ear, or whatever was missing without worrying too much about the patient’s body rejecting the foreign limb. In the case of organs the process would…

The mitochondria is one of the most interesting components of the eukaryotic cell. Endosymbiosis is the term modern scientists use for how the mitochondria came to be. Symbiosis translates from Greek to English as “living” “together.” Constrantin Mereschkowsky, known as the founding father of the theory of endosymbiosis, was one of people who started the concept of endosymbiosis, although he had called it “symbiogenesis,” defining it as: “the origin of organisms through the combination and…
