The Disadvantages And Advantages Of Adult Stem Cells

July 3rd, 2009 by admin

human stem cell research

Adult stem cells can be found in bone marrow, placentas, the umbilical cord, the spinal cord and numerous other tissues. Until recently, it was believed that stem cells adult derived could only create similar cells, although scientists can now reprogram genes within adult stem cells to act like protean embryonic stem cells, which can develop into more than 200 types of tissues. The safety of such techniques is still being studied, but scientists are hopeful that they’ll be able to treat everything from Parkinson’s and diabetes to heart disease and osteoporosis with stem cell therapies.

There are some advantages to using adult stem cells over embryo-derived stem cells. For one, adult cells are easier to harvest, as they can come from skin, muscle, bone marrow and fat. Often those treated with their own stem cells will not suffer immune system rejection. It’s also easier to encourage these already specialized cells to differentiate the way the scientists want them to, which is impressive considering they’re still not 100% sure what causes a cell to become a certain organ or tissue. Lastly, donated adult stemcells clear up the stem cell controversy surrounding the destruction of human embryos in the name of science.

Mice are not people. We know this. Even so, it’s hard not be excited that the first mouse has successfully regrown muscles and regenerated damaged tissue thanks to adult stem cells. Researchers from the University of New South Wales say the mice were given a gene making them resistant to chemotherapy, which clears out damaged cells and encourages new stem cells to take hold. “What has been the realm of science fiction is looking more and more like the medicine of the future,” said Peter Gunning, one of the study’s co-authors.

Adult stem cells can be used in many future cures, but there are also many hoops to jump through first. The danger of tumors is hard to escape, for instance, since scientists are still learning about the switches that turn gene expression and cellular activity on and off. Another issue is maintaining purity in stem cell cultures. Modern techniques in mouse stem cells have achieved just an 80% purity, which is not suitable for cellular transplanting into humans. If the transplant is impure, then germ layers may also be administered and cancerous tumors can emerge.

What You Should Know About Adult Stem Cells

June 29th, 2009 by admin

adult stem cell research

Adult stem cell research has advanced in leaps and bounds over the past decade. What was once viewed as inflexible, unable to proliferate and set in its ways has now been found to revert back to its earlier state. New evidence suggests that taking an adult stem cell from bone marrow or the spinal cord can become a blank slate like fetal stem cells, rather than possessing the sole ability to produce more bone marrow or more spinal cord tissue only. As a result of this finding, scientists hope to create more effective treatments for a wide range of degenerative diseases and disabling injuries.

While every cell in a newly forming embryo is a versatile stem cell, ready to become every tissue and organ in the human body, the adult stem cell is more rare; found in 1/10,000 bone marrow cells. Blood stem cells can be found in bone marrow, in the spinal cord, in the small intestine and in other areas that grow and change. For instance, in newborn babies, stem cells have been discovered in the umbilical cord, the hair, the teeth and the amniotic fluid. The role of stem cells in the adult body is to replace lost blood cells and repair damaged cells. However, scientists have found that, while present, the stem cells are not always naturally active within the adult body. Finding how to turn these cells on and off can be a vital component in self-repair.

One of the most exciting adult stem cell discoveries occurred in 2008 when researchers at the Salk Institute for Biological Studies in La Jolla, California coaxed mouse brain stemcells to differentiate into support cells and function with the surrounding neuronal network. When pampered in a Petri dish, scientists found that they could encourage oligodendrocyte cells to form the fatty myelin sheath that speeds up the transfer of electrical signals along the axons. They could also stimulate cellular growth in the hippocampus; the brain’s center for memories and learning. Scientists hope this research can provide a breakthrough in the treatment of multiple sclerosis, Alzheimer’s, stroke and epilepsy.

The most studied type of adult stem cell is called a “hematopoietic stem cell,” which is derived from bone marrow. Using transplants, scientists have restored immune and blood components using stem cells. Scientists have identified stem cells in the hippocampus region of the brain whose function is currently unknown and are looking at ways to induce proliferation or differentiation in these seemingly dormant cells. Muscle, blood and fat stem cells may be able to transform into other cell types under certain conditions, which will fuel many studies in the years to come.

Astral Projection: A Forgotten Art

June 27th, 2009 by admin

Generally speaking, the majority of people have at one point in their life heard the term ‘astral projection.’ This could’ve been from an enlightened friend, a book or a movie. Few people though understand that astral projection is a real event, and that it is something that everyone can do. Chances are very high that you have astral projected and didn’t even realize it.

You need to understand what astral projection really is. Astral projection is the ability of an individual to leave his or her body. Everyone has the ability to do this; everyone does this when he or she lay down to sleep at night. While sleeping the physical mind is resting and the subconscious mind takes control. A person astral projects while this is happening. However, the majority may never remember astral projecting.

While you are projecting, you can go anywhere you want to go. You should try recalling your childhood; you may be able to remember being able to do this after you went to sleep. Over time, you may have forgotten. When it involves astral projection there is no such thing as time or distance. You can go anywhere, since while asleep your physical body is at rest and your astral body travels.

The next question is what the astral body is. It is the ethereal body. The astral body is the invisible duplicate of the body. It houses all our desires and feelings. Does the astral body leave and not return? A silver cord connects the physical and astral bodies together.

This silver cord was connected the first time the astral body entered the physical body and can not be severed until the astral body leaves the physical body for the last time, death. It is the silver cord that prevents the astral body from straying away.

Another question that many have is where do you go when you astral project? The astral body goes to the astral plane, which is the ‘body double’ of the Earth. This vibrates faster then the physical Earth and those vibrations penetrate to the Earth’s core. Others define the astral plane as another dimension of reality. Most will agree though that there is more then one level to the astral plane.

It is only natural at this point to question whether or not there are any dangers to astral projection. The answer is yes and no. We have established that astral projection is something everyone is capable of doing. We have also stated that there isn’t a way that the astral body can leave the physical body and not come back. But as with anything you do, you need to keep your head about you. This means that you need to make sure you have solid thinking skills so that you are going where you want and you know what you want.

Astral projection can be dangerous if you practice it with an unsound mind. Anyone under the influence of drugs and alcohol can wind up involved in an undesirable predicament at lower levels of the astral plane.

It is essential that you know what it is you do and where it is you want to go. Your goal is to consciously astral project. You need to have complete control of what your astral body is doing. Your thoughts control your astral projection.

When you prepare yourself properly, beforehand you can train yourself to astral project very quickly. Some individuals prefer doing astral projection alone in their homes. Meanwhile, others learn various methods that help them gain control and enjoy their experiences while being lead by numerous professionals in the astral projection field.

You can find various other resources such as books online. For instance, you can create the right state of mind by listening to quality astral projection hypnosis recordings. It will help you relax and walk you through the various stages. This is beneficial since you can continue playing the recording repeatedly until your subconscious mind picks up the message that it is all right for you to leave your body.

Binaural beats is the most recent of astonishing sound technology advances. It plays slightly different tones of sound frequencies in the ears simultaneously. This works well for inducing relaxation and the deep state of meditation rather quickly. This is fundamental for the success of astral projection.

Don’t get frustrated if you are not able to successfully astral project the first time or even the second or third time. This is something that you must practice. It is not an ability that you have to acquire, we are all capable of doing it, many have just forgotten how and need to fine tune the natural skill.

Are you still not so sure? Think about the last time you dreamt you were flying or felt as if you had fallen. It feels similar to flying when the astral body moves throughout the astral plane. When the astral body returns to the physical body the sensation is much like falling and landing. Astral projection is naturally very real. We can all do it and find it beneficial in many ways. It does however; take time to fine-tune this natural ability.

Tips on Choosing Microscopes

June 26th, 2009 by admin

The world of microscopes has come a long way since light microscopy was first invented. Nowadays, the world is littered with various types of microscopes for assorted uses. If you are trying to decide which sort of microscope is best, then a little research is essential. Nevertheless, the world of the microscope is so interesting that you will not have any issues determining which of these devices is best.

Microscopes for those who are hobbyists are the simple light microscope of their senior high school days. These are relatively inexpensive, and the majority have a simple light source built into the device. You can view simple items that are mainly transparent, such as cells and bacterium, with this sort of microscope. Nevertheless, if you want to see solid objects, such as a coin, then this is not the right scope for you. On the other hand, if you purchase pre-loaded microscope slides, then a light microscope is the right type of device for viewing them.

Two other types of magnifying instruments available are the transmission electron microscope and the laser confocal microscope. You will not find either type in a school laboratory or somebody’s home though, since they are both made solely for use by scientists and researchers. The electron scopes utilize a vacuum to see the microscope images, and they can be very costly to operate. Used mainly in the technological and industrial world, a confocal microscope makes use of lasers in order to view incredible fluorescence images that can be displayed on a computer. These are also very expensive, but they provide a scientist with the option to view items that have not been seen for millions of years. Several other types of scopes include the atomic force microscope, the compound microscope and the inverted microscope.

The world of microscopes has come a long way since the beginning. People have gone from making use of thick pieces of glass to magnify items, to integrating lasers to help them to see into worlds that have for millions of years been nonexistent. These devices can be used to help you focus on becoming more involved in the world around you while also having the potential to help a child to become the next Pasteur. Regardless of what type of scope you choose to invest in, the main thing to bear in mind is that science is the key to unlocking some of the mysteries of the world and that can only provide knowledge in a world that is sometimes too chaotic.

Disappointed With Cosmic Ordering? Try Advanced Cosmic Ordering

June 24th, 2009 by admin

Many celebrities have admitted that much of their success is down to ‘cosmic ordering’, but what is it?

Many people know this as ‘the law of attraction’ but advanced cosmic ordering is far more specific than this.

Suppose for a moment that you had access to a cosmic ordering service and if you wanted something, all you had to do was think of it and it would appear before you. That would be amazing, wouldn’t it? The incredible thing is that every one of us can already do this - but most of us, even with limitless options continue to choose the same thing over and over again.

Think of it in this way - you have a menu with an unlimited number of options in front of you, but you only look at the very first line -bread. You keep ordering only this, perhaps feeling that you do not deserve more than this.

Imagine that you are fabulously wealthy. Picture yourself doing all of the things you’ve always wanted to do with no worries about anything. Imagine a permanent vacation, travelling by means of your private jet.

You wear the most expensive clothing and look absolutely marvellous. If you can picture this in your mind and hold it for a few minutes, you’re partially on your way. It is difficult to get a good picture of yourself in those circumstances if you’re like most people. For the majority of people, cosmic ordering seems beyond their reach. So what exactly is advanced cosmic ordering?

Advanced cosmic ordering can get results for those of us who have tried to use cosmic ordering before but didn’t get what they wanted. Perhaps you didn’t really believe it would happen. You need to reprogram your subconscious mind to eliminate the negative thoughts we are fed from an early age.

Over the years, this negative programming becomes internalized and holds us back from getting the things that we want for ourselves. This feeling that you can’t have or worse yet, don’t deserve success is reinforced by feeling envious of the success of others.

Belief that you don’t deserve the good things in life changes our order from the cosmic ordering service as quickly as it would in a restaurant when you realize there isn’t any money in your pocket.

Quantum physics shows us different ways to think about the Universe. Unlike the physics you had in school, the rules are new. It answers questions why some people get more than others do.

Your brain emits energy which is capable of affecting the smallest particle known to man - the quark. When a quark leaps from one level to another, it is called a quantum leap. When this change happens, the quark changes the properties of the atom containing it. Just think - if your mind can influence this change, than you can accomplish anything!

Most people don’t believe that changing your mind changes your circumstances. That’s because they tried it once and watched and waited, half-heartedly believing. In the laws of quantum physics, the observer changes what they observe just by watching it. If you watch a process and don’t believe it works but continue on out of duty, the process never turns out the way you want. You are the observer and changed what you observed, but not in a positive way.

With the right instruction and practice, you can get anything you want from the cosmic ordering system. The ancients knew it existed, every religion emphasizes belief to make prayers come true, and yet in this enlightened world, most people listen to neither science nor religion for the answer but continue blindly down the path of poverty.

Teaching your mind to ask for the things which are best for you takes practice; and you must first clear away the negative thought patterns which have been ingrained in you. Now there are many ways to speedup this process and let you clear away your old unsuccessful thought and behavior patterns.

Advanced cosmic ordering uses new audio technologies, including binaural tones. These sounds help attune your brainwaves to the correct frequency to communicate with the universe. This is the very state which Buddhist monks spend years in meditation to reach.

In combination with subliminal affirmations and self-hypnosis recordings, binaural sound helps you get rid of negative patterns and begin seeing results fast.

Advanced cosmic ordering works. Once you have mastered it, it is an incredible tool and everything you desire truly can be yours, but it needs just a bit of effort from you as well!

Surgical Loupes Provide an Eye-Opener!

June 24th, 2009 by admin

Who could live in a world in which surgical loupes and dental microscopes just didn’t exist? There are so many surgical procedures which rely on them and they simply would not be possible if the tools did not exist. Microscopes have proved to be rather critical, especially when it comes to diagnosing abnormalities. A doctor’s vision will make all the difference in what sort of treatment is given. To really comprehend this, you’ll have to be provided with the basic tools, and descriptions of them which are used in today’s treatments.

Surgical loupes have been proven time and again to be able to assist those in the medical as well as dental fields beyond all measure. If they did not have the loupes then there would be so many different things that they would be unable to see. Microsurgery is among the more delicate surgeries that use these small instruments, and it certainly wouldn’t be a possibility if the technology required to magnify an area just did not exist. The surgery is normally used for eye and ear surgery, as well as reattaching severed limbs.

The ability to magnify can spell success or failure of any type of procedure that requires it. Surgical Loupes such as these which can magnify an area specifically for dental purposes are generally utilized in the area of cosmetic dentistry. There is a flip-up style dental microscope which permits the dentist to change the magnification levels whenever he or she wants, and without any difficulty whatsoever.

Surgical Operating Microscopes (SOM) or surgical loupes have been in use by those in the medical field since the 1960s. However, they have been upgraded over the years to provide more intense magnification. The endodontist uses a dental microscope for the benefit it provides when treating the inside of the tooth. There is a very sensitive tissue in the center of our teeth that contains blood vessels and nerves. Without the use of the dental microscope, this area would not be visible to the dentist.

The illumination and magnification provided by one type of microscope is necessary for use by ear, nose and throat doctors. This microscope has a straight head instead of angled and the focal length is not the same as regular microscopes. This is an interchangeable part that can be taken off to switch lenses. This is necessary for reducing or increasing the magnification.

Another great feature in microscopes such as this is the ability to control the magnification level using nothing but your foot. Having a tiltable main head, the physician can actually rotate the head of the device 180 degrees if he so desires. There are also a number of other additions which can be purchased for the device.

Other types of surgical loupes or microscopes are used by ophthalmologists. They are necessary for surgeries that correct problems of the eyes. Also used for lasik surgery which is becoming more popular with those who need corrective surgery to improve their sight, these microscopes are becoming quite commonplace.

Magnification is very important, especially in the medical field when it comes to making the right diagnosis!
