Stem cell research provides hope for the cure of muscular dystrophy. Stem cells research is a relatively novel technology that utilizes primitive cells of human beings and develops them to come up with a variety of human cells including brain cells, blood cells and muscle cells. Scientists claim that stem cell research provides hope for and has the potential to reveal treatments and possibly even cures for serious diseases such as neurodegenerative diseases like Parkinsons and Alzheimers disease,...

Genetic engineering is the alteration of genetic material by direct intervention in genetic processes with the aim of creating new substances or improving the functions of the existing ones. It is a young, exciting, and controversial branch of the biological sciences. It brings with it the possibilities for cure of several genetic diseases and numerous material improvements to the every day life of man. Human genome projects is one of the signs of benefit of genetic engineering where as there are...

Birds in the Hawaiian ecosystem are facing extinction due to degradation and loss of their habitat from effects of animals such as the feral ungulates. These animals eat native plants and destroy ground cover through their hooves and grazing activities. According to the bird channel website, there has been a 64 reduction in the birds population during the period 1973-2000. It is estimated that nearly two thirds of birds extinctions in the United States have happened in Hawaiis habitats. These birds...

Drug resistance has increased in the recent years. This is because of the poor use of drug and drug products. Because of drug resistance, human populations are faced with the danger of disease out breaks and emergence of new diseases from resistant strains. This paper is going to look into some of the factors that contribute to the increase of these risks and measures that can be taken to avoid the situation. Human population is faced with a danger of being infected with emerging diseases. Emerging...

Glycosylation refers to an enzymatic process involving the linking of saccharides to generate glycans (Haltiwanger  Lowe, 2004). This carbohydrates are usually linked to proteins and lipids in the cell. This is an important process in the body as it produces glycans which are significant biopolymers that are found within cells. The glycans that are generated have several structural and functional functions within membranes as well as secreted proteins especially in the folding of proteins....

Article Comparison of Two Chromogenic Media for Selective Isolation of Vancomycin Resistant Enterococci from Stool Specimens.  Journal of Clinical Microbiology, 47 4113-4116 Authors Heidrun Peltroche-Llacsahuanga, Janetta Top, Josefine Weber-Heynemann, Rudolf   Ltticken, and Gerhard Haase (2009). Summary Overview The purpose of the study is to compare the efficacy of two chromogenic media in on rapid detection of Vancomyin Resistant Enterecocci (VRE). The two chromogenic media under...

Stems cells are cells which are capable of dividing for indefinite periods in culture and produce multiple specialized cell types. These cells have the ability of developing into many tissues such as bone, brain, muscle, and other body tissues. Embryonic stem cells are primitive cells which are capable of differentiating to any adult cell (Kurkalli, Gurevitch, Sosnik, Cohn  Slavin, 1994). Improvement in stem cell usage Any injury to adult nervous system can be very devastating owing to the...

Medicinal marijuana is also known as Medical Cannabis. Physicians for patients requiring stimulation of all sorts prescribe it as herbal therapy. For example, it is used to induce hunger in those with low appetite, treat glaucoma, avert vomit and diarrhea as well as relieving pain. It has been in use as early as 737 B.C. Medical marijuana can be administered through drinking, smoking, vaporization and in capsule form. Some of the countries that use marijuana for medicinal purposes include Austria,...

In the article written by Arne Lindqvist entitled Cyclin B-Cdk1 Activates Its Own Pump to Get into the Nucleus, the author points out that the transition to mitosis involves the importation of the kinase complex into the nucleus through the modification of the activity of the nucleocytoplasmic transport machinery. According to the author, Cdk1 is complex because the cyclin B phosphorylates hundreds of target proteins that would promote the transition from the interphase to the mitosis (Lindqvist...

1) Genetic Modification of Food - Agree or DisagreePost in the discussion area a website or news article relating to genetic modification of organsisms, especially pertaining to food resources. Are you in favor of or against genetic modification of food Answer httpwww.ornl.govscitechresourcesHuman_Genomeelsigmfood.shtmlGenetic modification of food has become a controversial subject, in my opinion, without reason. By genetically modifying food items, we are taking advantage of the limited resources...

In 2008 Michael Bernitsas invented a device that would help in harnessing renewable sources, the device which he named Vivace utilizes vortex induced vibration, and these forms of vibrations have been destructive in the past example the destruction of the Tacoma Bridge. According to Bernitsas these destructive forces can be controlled and converted into electric energy using his device. The prototype device created by Bernitsas contained a submerged cylinder that is supported by a spring, when this...

Most people often become too attached to the external appearance of flirting that they do not even bother to wonder what is exactly going on within the body while a man is flirting with a woman, and vice versa. Everything that goes on outside must have had a physiological basis  this includes ones emotions, words, choices and actions such as flirtation. Flirtation is in fact the result of the coordination of the external parts of the body, certain internal organs and most of all, the hormones....

Sauropods were large, long-necked plant-eating dinosaurs that first appeared in the Triassic Period and proliferated in the Jurassic. They had tiny heads that logded even tinier brains, and long tails which counterbalanced their very long necks. To the infraorder of sauropods (lizard-footed) belonged the five families of Diplodocids, Brachiosaurids, Carnasaurids, Titanosaurids and Cetiosaurids. The dinosaurian species Apatosaurus belonged to the sauropod family of Diplodocids they were land-roaming...
