BIOTECHNOLOGY: Save World Standing Alone

"Save Our World Standing Alone"

Only Politicians and Higher officials have the key to save our world from pollution and do all sorts of this stuff?

Why Cant you and me do the same without any influence... Is that possible??? Yes.... Only a small care on our world and the intensity to do that is more than important. People keep on insisting to save our earth but none say how to do it.

We Biotechnologist give you the ultimate key to Save our world to prove that we are true citizens of this earth.

These are the ways which helps to save our world from increasing pollution and the ultimate way to save energy for our future generation.

1. Stop your vehicles when you are in traffic signals. Do you feel this is a very tough one to do? Not at all. By doing this you can save energy and at the same time you can reduce pollution. You may ask "Is the holes in the ozone layer, litres and litres of petrol is going to be saved by me alone? Yes of course. Biotechnology answers you at last for all this at the end.

2. Stop the water usage unnecessarily. Cant you stop the tap when not in use? A survey made by a Bio tech Group states that nearly 5 litres of water at least is wasted by a single person in a single day. At least 1000 of you started saving water by reading this nearly 5000 litres of water can be saved in a day.If 1000 people start saving water, in 1 day (1000*5=5000litres) of water can be saved.Shocked??? Think how much litres of water can be saved in just 10 years.

3. Stop using Plastics. Is this going to be a great issue for all of us? Plastics cannot be decomposed soon and it stays a garbage till last. We can easily stop using plastics and so we make a great contribution in reducing pollution to our atmosphere.

4. Switch off fans and tube lights when not in use. By this we can save lots and lots of electricity. We don't have a source of electricity merely by 2030. Is this going to be a great work to switch off the fans and lights when not in use. Not at all.
Fact to know: Do you ever know that charging your phones costs twice more than the energy required for a tube light to glow for 1 day and a fan to keep running for more than 8 hours". So stop charging your phones and ipod's after it is fully charged so that electricity is also saved and at the same time the life time of battery will also be increased.

5. Try to use Bio fuel and solar based vehicles. If you are going to buy a Car or bike let it may be a Bio vehicle. Stop using vehicles which pollutes atmosphere a lot.

We have given you 5 basic things to save energy and stop polluting the atmosphere. These facts may be a cheap and already known plans for you. But we have stated this because only a 3% of us follow these facts and the others remain to waste all this.

Stop talking and show in action. If each and every one of us who read this fact and start doing all this at least 1% of energy can be save for our future generation. We Biotechnology community insist you to do all this basic plans to save energy and be ecofriendly always.

Be Eco-Friendly in all things you buy. For example, Nowadays we get ecofriendly notebooks that are prepared from the sugarcane wastes. These are exactly Eco-friendly and what happens is that indirectly we stop using other notebook companies who cut trees and plants for the production. If we stop using those kinds of notebooks they stop cutting trees and making papers. At least a tree can be saved which may last up to 200 years and give fruit full usage to human kind.

"If you cant follow these small works feel ashamed of yourself"

Be Eco-Friendly... Never Destroy Plants and Trees..... Save Electricity and Water...

Biotech Information Mesothelioma

Also called: Malignant mesothelioma

The tissue that lines your lungs, stomach, heart and other organs is called mesothelium. Mesothelioma is cancer of that tissue. It is a rare but serious type of cancer. It usually starts in the lungs, but can also start in the abdomen or other organs. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles. It can take a long time - 30 to 50 years - between being around asbestos and getting the disease. Treatment includes surgery, radiation, chemotherapy or all three.

Malignant mesothelioma is a disease in which malignant (cancer) cells form in the lining of the chest or abdomen.

Malignant mesothelioma is a disease in which malignant (cancer) cells are found in the pleura (the thin layer of tissue that lines the chest cavity and covers the lungs) or the peritoneum (the thin layer of tissue that lines the abdomen and covers most of the organs in the abdomen). This summary is about malignant mesothelioma of the pleura.

Being exposed to asbestos can affect the risk of developing malignant mesothelioma.

Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor.

Many people with malignant mesothelioma have worked or lived in places where they inhaled or swallowed asbestos. After being exposed to asbestos, it usually takes a long time for malignant mesothelioma to occur. Other risk factors for malignant mesothelioma include the following:

* Living with a person who works near asbestos.
* Being exposed to a certain virus.

Possible signs of malignant mesothelioma include shortness of breath and pain under the rib cage.

Sometimes the cancer causes fluid to collect around the lung or in the abdomen. These symptoms may be caused by the fluid or malignant mesothelioma. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:

* Trouble breathing.
* Pain under the rib cage.
* Pain or swelling in the abdomen.
* Lumps in the abdomen.
* Weight loss for no known reason.

Tests that examine the inside of the chest and abdomen are used to detect (find) and diagnose malignant mesothelioma.

Sometimes it is hard to tell the difference between malignant mesothelioma and lung cancer. The following tests and procedures may be used:

* Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits, exposure to asbestos, past illnesses and treatments will also be taken.
* Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.

RNA and DNA


Biotechnology DNA RNA

Biotechnology is technology based on biology, especially when used in agriculture, food science, and medicine. Although it has been utilized for centuries in traditional production processes, modern biotechnology is onlyyears old and in the last decades it has been witnessing tremendous developments. Bioengineering is the science upon which all Biotechnological applications are based. With the development of new approaches and modern techniques, traditional biotechnology industries are also acquiring new horizons enabling them to improve the quality of their products and increase the productivity of their systems.Before , the term, biotechnology, was primarily used in the food processing and agriculture industries. Since the s, it began to be used by the Western scientific establishment to refer to laboratorybased techniques being developed in biological research, such as recombinant DNA or tissue culturebased processes. In fact, the term should be used in a much broader sense to describe the whole range of methods, both ancient and modern, used to manipulate organic materials to reach the demands of food production. So the term could be defined as, The application of indigenous and/or scientific knowledge to the management of parts of microorganisms, or of cells and tissues of higher organisms, so that these supply goods and services of use to the food industry and its consumers.

Combinations of Plants Bio-tech

Combinations of plants and other organisms were used as medications in many early civilizations. Since as early asBC, people began to use disabled or minute amounts of infectious agents to immunize themselves against infections. These and similar processes have been refined in modern medicine and have lead to many developments such as antibiotics, vaccines, and other methods of fighting sickness.In the early twentieth century scientists gained a greater understanding of microbiology and explored ways of manufacturing specific products. In , Chaim Weizmann first used a pure microbiological culture in an industrial process, that of manufacturing corn starch using Clostridium acetobutylicum to produce acetone, which the United Kingdom desperately needed to manufacture explosives during World War I.The field of modern biotechnology is thought to have largely begun on June.Indianborn Ananda Chakrabarty, working for General Electric, had developed a bacterium derived from the Pseudomonas genus capable of breaking down crude oil, which he proposed to use in treating oil spills. A university in Florida is now studying ways to prevent tooth decay. They altered the bacteria in the tooth called Streptococcus mutans by stripping it down so it could not produce lactic acid.

All Bio Tech Applications

Biotechnology has applications in four major industrial areas, including health care, crop production and agriculture, non food uses of crops e.g. biodegradable plastics, vegetable oil, biofuels, and environmental uses. For , one application of biotechnology is the directed use of organisms for the manufacture of organic products s include beer and milk products. Anotheris using naturally present bacteria by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities bioremediation, and also to produce biological weapons.Red biotechnology is applied to medical processes. Anotheris the using of enzymes as industrial catalysts to either produce valuable chemicals or destroy hazardous polluting chemicals s using oxidoreductases are given in Feng Xu“Applications of oxidoreductases Recent progress” Ind. Biotechnol. ,. White biotechnology tends to consume less in resources than traditional processes used to produce industrial goods.Green biotechnology is biotechnology applied to agricultural processes. Anis the designing of transgenic plants to grow under specific environmental conditions or in the presence or absence of certain agricultural chemicals. One hope is that green biotechnology might produce more environmentally friendly solutions than traditional industrial agriculture. Anof this is the engineering of a plant to express a pesticide, thereby eliminating the need for external application of pesticides. . Whether or not green biotechnology products such as this are ultimately more environmentally friendly is a topic of considerable debate.The term blue biotechnology has also been used to describe the marine and aquatic applications of biotechnology, but its use is relatively rare.The investments and economic output of all of these types of applied biotechnologies form what has been described as the bioeconomy.

Bio-Informatics

Bioinformatics is an interdisciplinary field which addresses biological problems using computational techniques, and makes the rapid organization and analysis of biological data possible. The field may also be referred to as computational biology, and can be defined as, "conceptualizing biology in terms of molecules and then applying informatics techniques to understand and organize the information associated with these molecules, on a large scale." Bioinformatics plays a key role in various areas, such as functional genomics, structural genomics, and proteomics, and forms a key component in the biotechnology and pharmaceutical sector.

Pharmacogenomics

Pharmacogenomics is the study of how the genetic inheritance of an individual affects his/her body’s response to drugs. It is a coined word derived from the words “pharmacology” and “genomics”. It is hence the study of the relationship between pharmaceuticals and genetics. The vision of pharmacogenomics is to be able to design and produce drugs that are adapted to each person’s genetic makeup.Pharmacogenomics results in the following benefits Development of tailormade medicines. Using pharmacogenomics, pharmaceutical companies can create drugs based on the proteins, enzymes and RNA molecules that are associated with specific genes and diseases. These tailormade drugs promise not only to maximize therapeutic effects but also to decrease damage to nearby healthy cells.

Herceptin

Biotechnology is also commonly associated with landmark breakthroughs in new medical therapies to treat diabetes, hepatitis B, hepatitis C, cancers, arthritis, haemophilia, bone fractures, multiple sclerosis, cardiovascular as well as molecular diagnostic devices than can be used to define the patient population. Herceptin, is the first drug approved for use with a matching diagnostic test and is used to treat breast cancer in women whose cancer cells express the protein HER Modern biotechnology can be used to manufacture existing drugs more easily and cheaply. The first genetically engineered products were medicines designed to combat human diseases. To cite one , inGenentech joined a gene for insulin and a plasmid vector and put the resulting gene into a bacterium called Escherichia coli. Insulin, widely used for the treatment of diabetes, was previously extracted from the pancreas of bovines and pigs. It was very expensive and often elicited unwanted allergic responses. The resulting genetically engineered bacterium enabled the production of vast quantities of human insulin at low cost.Since then modern biotechnology has made it possible to produce more easily and cheaply human growth hormone, clotting factors for hemophiliacs, fertility drugs, erythropoietin and other drugs. Most drugs today are based on aboutmolecular targets. Genomic knowledge of the genes involved in diseases, disease pathways, and drugresponse sites are expected to lead to the discovery of thousands more new targets.

Genetic testing

Genetic testing involves the direct examination of the DNA molecule itself. A scientist scans a patient’s DNA sample for mutated sequences.There are two major types of gene tests. In the first type, a researcher may design short pieces of DNA “probes” whose sequences are complementary to the mutated sequences. These probes will seek their complement among the base pairs of an individual’s genome. If the mutated sequence is present in the patient’s genome, the probe will bind to it and flag the mutation. In the second type, a researcher may conduct the gene test by comparing the sequence of DNA bases in a patient’s gene to a normal version of the gene. Some genetic tests are already available, although most of them are used in developed countries. The tests currently available can detect mutations associated with rare genetic disorders like cystic fibrosis, sickle cell anemia, and Huntington’s disease. Recently, tests have been developed to detect mutation for a handful of more complex conditions such as breast, ovarian, and colon cancers. However, gene tests may not detect every mutation associated with a particular condition because many are as yet undiscovered, and the ones they do detect may present different risks to different people and populations.

Gene therapy

Gene therapy may be used for treating, or even curing, genetic and acquired diseases like cancer and AIDS by using normal genes to supplement or replace defective genes or to bolster a normal function such as immunity. It can be used to target somatic body or germ egg and sperm cells. In somatic gene therapy, the genome of the recipient is changed, but this change is not passed along to the next generation. In contrast, in germline gene therapy, the egg and sperm cells of the parents are changed for the purpose of passing on the changes to their offspring. Ex vivo, which means “outside the body” Cells from the patient’s blood or bone marrow are removed and grown in the laboratory. They are then exposed to a virus carrying the desired gene. The virus enters the cells, and the desired gene becomes part of the DNA of the cells. The cells are allowed to grow in the laboratory before being returned to the patient by injection into a vein. In vivo, which means “inside the body” No cells are removed from the patient’s body. Instead, vectors are used to deliver the desired gene to cells in the patient’s body.Currently, the use of gene therapy is limited. Somatic gene therapy is primarily at the experimental stage. Germline therapy is the subject of much discussion but it is not being actively investigated in larger animals and human beings.As of June , more thanclinical genetherapy trials involving about , patients have been identified worldwide. Aroundof these are in the United States, with Europe havingThese trials focus on various types of cancer, although other multigenic diseases are being studied as well. Recently, two children born with severe combined immunodeficiency disorder “SCID” were reported to have been cured after being given genetically engineered cells.Gene therapy faces many obstacles before it can become a practical approach for treating disease. At least four of these obstacles are as follows Gene delivery tools. Genes are inserted into the body using gene carriers called vectors. The most common vectors now are viruses, which have evolved a way of encapsulating and delivering their genes to human cells in a pathogenic manner. Scientists manipulate the genome of the virus by removing the diseasecausing genes and inserting the therapeutic genes. However, while viruses are effective, they can introduce problems like toxicity, immune and inflammatory responses, and gene control and targeting issues. Limited knowledge of the functions of genes. Scientists currently know the functions of only a few genes. Hence, gene therapy can address only some genes that cause a particular disease. Worse, it is not known exactly whether genes have more than one function, which creates uncertainty as to whether replacing such genes is indeed desirable. Multigene disorders and effect of environment. Most genetic disorders involve more than one gene. Moreover, most diseases involve the interaction of several genes and the environment. For , many people with cancer not only inherit the disease gene for the disorder, but may have also failed to inherit specific tumor suppressor genes. Diet, exercise, smoking and other environmental factors may have also contributed to their disease. High costs. Since gene therapy is relatively new and at an experimental stage, it is an expensive treatment to undertake. This explains why current studies are focused on illnesses commonly found in developed countries, where more people can afford to pay for treatment. It may take decades before developing countries can take advantage of this technology.
