The Disagreement Of Stem Cell Research

Friday, April 1st, 2011

A huge controversy touches upon stem cell research because of the way embryos are created, used and destructed for study purposes alone. The main interest in stem cell research comes from the possibility to develop treatments and cures for the irrecoverable diseases that plague humanity such as cancer, Alzheimer’s, diabetes, Parkinson’s, heart attacks and so on. Yet, lots of pro-life supporters who argue against stem cell research don’t really know that there are many processes and lab tests that work with stem cells without causing any harm to human embryos. Even if they have a lower biological potential, adult stem cells for instance represent a great study material and a constant replacement for embryonic stem cells samples.

Unlike adult stem cells, embryonic stem groups can develop into absolutely any type of cells specific to the body. Moreover, stem cell research has proved the fact that stem cells collected from embryos are more valuable in the treatment of nervous disease. There are bad bits to embryonic stem cells as well because very often they are rejected by the immune system. Such an issue ought to be known to parents who store umbilical cord stem cells, so that they may not be given false information that such samples can solve any future disease their child could be fighting against.

The truth is that stem cell research has more to do before real treatments can be performed in full safety and knowledge of the outcome. The only kind of stem cell transplantation that is no longer an issue or secret for the medical world is bone marrow transplantation, that has been practiced for almost fifty years now with great success. Otherwise, the rest of the cures available on the basis of stem cells are usually experimental and pretty expensive. For the moment, stem cell research tries to find alternative sources for cells, other than embryos.

A great success was reputed by stem cell research in 2007 when three stem cell lines were created at the Advanced Cell Technology Institute without causing any harm to parenting embryos. Such significant achievements of stem cell research have been unparalleled so far in the history of medicine. In the same year, 2007, it was discovered that the amniotic fluid surrounding the fetus in the uterus contains stem cells that can differentiate and develop into bones, blood vessels, muscles, nerves and organs. This new resource for tissues could enhance the possibility to develop methods to repair injured or malfunctioning organs.

Staking A Young Tree

Monday, March 28th, 2011

When a tree is in the young stages, one of the most vital things you need to provide for it in addition to water and nutrients is support. If you don’t hold up the tree somehow, it might end up bending in a certain direction and growing extremely crooked for the rest of its life. So no matter what, you should always have some kind of support.

The most popular method of keeping young trees upright is to put long stakes into the ground on either side, and tie loops around the tree. Each loop should be fairly loose to allow for further expanding of the trunk. Lots of people just have a stake on one side of the tree, but this is not a good practice because it generally doesn’t allow for further growth of the tree.

You should only be staking your tree if you think that wind and other forces might be literally moving the ball of roots within the ground. Your staking should prevent all of this movement, because this is the most harmful thing that can happen to a young tree. It causes the roots to be in motion too much and not be able to properly get a hold on the soil so that the tree can develop normally.

Before you stake a tree, you should be completely sure that it needs it. If you constrict the movement and growth of a tree that doesn’t need to be tethered down, you could harm it beyond repair. For example, the staking mechanism you use could cause abrasion or “rashes” on the trunk. This will happen anyways, but why have it happen needlessly? Also, staking gives your yard an unnatural look and can present a hazard for people walking or running across the yard.

The staking process is actually rather simple. Just take 3 stakes and tie each one separately near the base of the trunk. If you use some sort of tether to prevent rope burn on your tree, that would be an even better solution. These can be purchased at any gardening shop, and are designed to be friendly to the bark of the tree. It is much better to stick with these instead of bare rope, to minimize the amount of friction the tree endures.

When you think your tree has been staked long enough to stand on its own, you should remove the stakes from the ground as soon as humanly possible. Every moment the tree is constricted it is losing some of its vitality. As soon as it seems like the wind is dying down around your area, look on the weather reports and see how much wind is forecasted. If the skies will be pretty clear for a while, you should at least temporarily take off the stakes.

To wrap it all up, you should never deny your tree a good staking. It is a completely necessary thing to do in certain situations. It is very crucial to understand when those occasions are, though. Staking a tree that doesn’t need it can be as damaging as not staking a tree that does need it. It might be beneficial for you to consult an expert, and get their opinion as to whether your tree should be staked, and for how long.

Tips For Emergency Preparations

Monday, March 21st, 2011

If you live in a storm-prone area, you should be used by now on what to do, where to go and what to have to be prepared for bad weather.  However, if you’re not used to getting pummeled by high winds and hard rain, you probably don’t have an idea how best to face a storm situation.

 

For starters, storms do not just come without a warning.  Weather stations monitor the atmosphere day in and day out.  If a storm is possible, they will issue two types of warnings:

 

Storm watch – is issued when there is a possible storm in your area.  You probably will be experiencing a dark, cloudy sky, an unusually windy day and some rain.  The storm may or may not come, but this is the time to keep tuned to your local radio for news and updates.

 

Storm warning – is issued when a storm is headed toward your area.  Try to stay indoors as much as possible.  Or if residents are advised to evacuate to a safer place, go as early as you can.  Don’t wait until the last minute to leave your house.  By that time, the streets could be flooded and traffic is bad.  You don’t want to be caught in your car in bad weather.

 

Blizzard – usually occurs in winter and means heavy snow, strong winds and wind chill.  When a warning is issued, avoid traveling as much as possible and stay indoors.  There is no use exposing yourself outdoors where you could get trapped in traffic or in locations where you will be difficult to reach or worse, find

 

For all our technology, no one can stop a storm from coming.  The only way to survive it is to be prepared to face the emergency.  Things don’t always go bad during storms, but weather is unpredictable and anything can happen.  To help you prepare for a storm emergency, here are a few tips:

 

Dress up.

Wear enough clothes to keep yourself warm.  Heat may not be available in your house so get extra coats and blankets to maintain your body temperature sufficiently.  Have your mittens, gloves, hats, socks and boots ready as well.

 

Have food ready.

Emergency provisions are a must during storm emergencies.  Make sure you stock on no-cook food, canned food, some candy and other non-perishable items.  And don’t forget can openers, scissors or utensils.  If the storm gets too bad and the streets are flooded, you will have a difficulty going out to the grocery shops.  Besides, stores might be closed.

 

Keep bottles of water handy.  Clean water may be hard to come by during really bad conditions and the worst thing you can do is suffer from dehydration because you were not prepared.  Keep a supply of at least one gallon for every person per day that will last for 3 to 4 days.

 

Fill the tub.

You’ll need more water for washing and flushing the toilets.  When the power is out, your water pump won’t operate, so best fill your bath tub, water containers and pails with water.  If you have small children in the house, take precautions by covering deep containers and keeping children away from the bathroom unless necessary.

 

Emergency kit

Have a medical or first kit ready and make sure it’s freshly-stocked.  It should contain disinfectants, gauzes, cotton balls, Q-tips, medicated plasters and necessary medicines.  It’s also a good idea to have another kit in your car.

 

If anyone in your family is under special medication, make sure you have enough supplies to last until after the storm is over and drug stores are open.

 

Lights off

Expect power outages during storm emergencies.  You won’t have any electricity, so stock on candles, flashlights and emergency lights.  Have extra fresh batteries and matches in case you run out.

 

If you can’t turn on the TV, have a battery-powered radio tuned in to a station that covers your area.  Media will monitor the storm and will keep you updated.

 

You might need hot water during the period when power is not yet available, so keep a small tank of gas around just in case.  Your outdoor gas grill will do nicely.

 

Get an alternate shelter.

If you think your house will suffer considerably, it’s a good idea to consider an alternate shelter.  It could be an evacuation center or another house or building that is safer.  Make sure you have enough gas in your tank in case you need to get out of the house and move someplace.  Keep to a higher ground where you have better chances of being safe and dry.

Shaping Trees For Different Situations

Saturday, March 19th, 2011

Through the use of pruning techniques, it is possible to shape your tree to a certain style. There are seven main tree shapes that all have their own benefits for certain situations. During the growth of the tree, simply cut off the unneeded branches, tie the wanted branches into the proper shape, and you will be able to shape it however you want. However, for some of the more advanced shapes, equally advanced pruning techniques are required. There are many books written on this subject.

Usually, if you’re trying to get your tree to a certain shape, all the tying and pruning should occur in the fall. This will encourage the shape to stick, since no fruits will be produced at that point in time. Each of the different shapes is very useful in certain situations. So, here are some different types of shapes you are able to choose from.

Standard trees hardly need any explanation. These are the varieties that are most common, and probably what you picture when you think of any tree. No specific shaping is required to get the shape to take this form. Just let it go and prune it as you would normally, and unless you have a strangely deformed tree then it should end up being a standard tree.

It is possible to turn a standard tree into a bush tree through pruning. The branches take the same shape, but the stem or trunk of the tree is noticeably shorter. This can be beneficial if you want to grow trees, but don’t want to block the view. For example, my house has a great view of the Rocky Mountains. I didn’t want to sacrifice this gorgeous view, so I grew my trees up as bush trees.

Cordons are a type of tree that you might not be familiar with. It consists of one stem with no branches. It is planted at an angle so that it arches up over the ground. Through the course of its growth, all branches are removed. These are beneficial because they take up very small amounts of space and more can be fit in a certain square footage. The only negative aspect is that they produce smaller amounts of fruit per tree.

Espalier trees grow with a single vertical stem in the center, and several horizontal branches on each side. These allow for long rows of trees, while still producing large amounts of fruit. If you operate an orchard, you probably use this shape to fit as many trees as possible into the area you have.

Fan trees use the same theory as espalier trees. However, the shape is slightly different. The same central vertical stem is used, but the connected branches are not horizontal; they grow in the same pattern as a standard tree, only they are two dimensional rather than three dimensional. They are also used to save space, and are used instead of espalier trees for certain types of trees that do better with sloped branches.

Another type of espalier is the step-over espalier. They are like a normal espalier, but with just one horizontal branch very close to the ground. They are particularly interesting because they still produce delicious fruit while providing a border for whatever you want. I have used step-over trees to fence of my garden. They are definitely my favorite shape of tree, mainly because they are like a fence that bears fruit. What’s not to love?

As you can see, each of these shapes has its own benefits and negative aspects as well. If any of these sounds like they would be a good fit for your garden, you can ask your local nursery employees for advice on reading material that will help you achieve your goals. Most of the time, getting the tree into the desired shape is a very easy process and just requires some guidance at the beginning.
