what is stem cell therapy and how does it work?

My 24 year old son has recently been diagnosed with ALS, I am
looking for anything that may help him. Stem cell therapy,outside the USA may be the answer but what exactly is it and how does it work? Is it safe? I know it is not a cure but can it help? Where is the best place to have it done? Please help me with my questions .

Stem cells are undifferentiated cells which have the unique potential to produce any kind of cell in the body and self-renewal capacity. Medical researchers believe stem cells have the potential to change the face of human disease by being used to repair specific tissues or to grow organs.  (+ info)

What age should children have a cell phone?

This is a repeat question, but I would like to get some more answers.

1. What are your feelings about kids/teens having cell phones?
2. What age is appropriate for a child/teen to get a cell phone?
3. What is your age?
4. Do you have children? If yes, what are their ages?

Please answer the last 2 questions - I am interested in how age and parental status affect opinions. Thanks!

1. What are your feelings about kids/teens having cell phones?

I'm perfectly fine with kids having cell phones. To me, parents only see the bad in cell phones and not the good. A great example: For those very overprotective parents who let their child go to someones house and you call that persons house nonstop to check on your child. Instead get them a phone so you can aviod conflict with other parents or whomever.

2. What age is appropriate for a child/teen to get a cell phone?

I think 12ish is good, but I know tons of kids who got phones way before then. It depends on the situation, sometimes. I got my daughter a cell phone when she was 11 because she attended a school that wasout of the district. Therefore she took two schoolbuses. She also had after school activities and sometimes she missed the bus. Calling on school phones can be a hassle because they administrators bug them about who they call and why. It's easier with a celll phone because they can simply call, text, e-mail, or send their parents a voice SMS.

3. What is your age?
I'm in my 30's

4. Do you have children? If yes, what are their ages?
Yes I do.

Does keeping a cell phone in your pocket affect your balls?

I keep my cell in my pocket. Its near my nuts and cock. Will the rays it emits or receives hurt those areas?

People disagree, but it cellphone radiation has been linked to cancer by many scientists, so if u wanna have kids one day maybe keep it away from there. I read somewhere a cell should be at least a metre (3 foot/1 yard) from you. Hard if u r carrying it around but I would say just make sure u take it out your pocket when u get home  (+ info)

What is small cell carcinoma, and why is edema in the upper body a serious complication.?

A family member has small cell carcinoma being treated with chemotherapy in the lung/thoracic area, and recently has developed edema in the arms and chest (not sure specifics of where in the chest the edema is). What is this type of cancer and what is the concern with the edema when it develops secondary to the cancer? Thank You.

oedema of the upper body is due to blockage (partial) of the superior vena cava (the main vein which drains the part of the body above the level of the heart). this is due to infiltration of the vein by the malignant tumour. its a bad prognostic factor.

as for small cell carcinoma, it is a highly malignant tumour of the lungs, and spreads rapidly. it also produces certain hormones that mimic hormonal imbalance states (paraneoplastic syndrome).

u can type in "small cell carcinoma" on wikiepedia and check the other details for urself.  (+ info)

How harmful are cell phone tower emissions?

A cell phone tower was recently built on the roof directly above my fifth-floor apartment unit. (It's not more than twelve feet away). A friend tells me I should move out immediately, but due to money issues it's not an immediate option for me. How real (and bad) are the health risks?

unsure....but this is why i don't have a cell phone!!!!!!!!  (+ info)

What are some causes and what does a low white blood cell count in a woman mean?

I went to have my annual appt with my gynecologist and they did blood work because I've been having really bad cramps and heavy flow with clotting while on my period. My doc thinks I may have Endometriosis. Well the blood work came back my platlette level is low as well as my white blood cell count. So she has sent me to see a Hematologist next week. I'm scared because I don't know what to expect. I need some answers. Thanks!

I kept getting infections and my doctor diagnosed low white blood cell count, but the only treatment he put me on was taking 3 B-vitamins a day for a few weeks and he told me to increase the amount of protein I ate. My last blood cell count was normal, so it worked for me.

LOW RED BLOOD CELL COUNT (Anemia, low hemoglobin, low hematocrit)

Red blood cells carry oxygen and nutrients throughout the body. A complete blood count (CBC) is a blood test used to check your blood count. The RBC, hemoglobin, and hematocrit are tests to see if you have low red blood count.

When you have low red blood cell count you may feel:

Short of breath
Increase in your heart rate
Dizzy or lightheaded when you change positions quickly
If you suffer from low red blood cell count, you may experience:

Chest Pain
Pale skin
Things you can do to help manage your low red blood count:

Rest between activities.
Plan ahead and save your energy for the most important activities.
Avoid or stop activities that make you short of breath or make your heart beat faster.
Ask others for help.
Eat a diet with adequate protein and vitamins.
Drink plenty of non-caffeinated and non-alcoholic fluids.
When to call your doctor or health care provider about low blood counts:

Severe weakness.
You feel dizzy or lightheaded.
Your heart is beating faster.
You feel short of breath or are having difficulty breathing.
Call immediately if you are having chest pain.
Your doctor or health care provider may prescribe or suggest to treat your low red blood count:

When you suffer from low blood platlet count you may notice:

Increased bruising
Petechiae (red dots on your skin described above)
Bleeding from nose, gums, rectum
Call your doctor immediately if you have sudden, severe unexplained pain.

Things you may do to decrease your risk of bleeding if you have low blood platlet count:

Do not take medications that interfere with the platelets being able to form a clot.
Ibuprofen (Advil®, Motrin®)
Naproxen (Aleeve®)
If you are not sure about taking any medication, check with your doctor, nurse or pharmacist.
Do not use rectal suppositories or take your temperature rectally.
Use caution or avoid flossing your teeth.
Use a very soft bristle toothbrush or oral swabs as recommended by your doctor or health care provider.
If your gums bleed, rinse with cold water. If bleeding does not stop call your doctor or health care provider.
Avoid activities that increase your risk of bleeding when you have low blood platlet count:
Contact sports
Amusement park rides that involve fast or quick motion.
Strenuous exercise.
Avoid or limit the use of sharp objects such as knives, razors.
Hold pressure on any cut or scrape for at least 5 minutes.
When to call your doctor or health care provider about low blood count:

Bleeding that will not stop after 5 minutes of pressure.
Bleeding that occurs spontaneously (by itself), without injury.
New or unexplained pain
Fall or experience trauma or injury
Feel dizzy or lightheaded
Have difficulty seeing or double vision.

I know this isn't much, but I hope something here helps. I KNOW how scary it can be, so I'm keeping my fingers crossed for you !
Good Luck !!  (+ info)

What type of disorder is a sickle cell and what part of the body does it affect.?

I'm sort of conused about this when I looked ut up. Is sickle cell disease a
single pair of genes
unknokn or other?

Do any of these apply to sickle cell disease?

Sicke cell is caused by an abnormal homozygous hemoglobin (called S). Sickle cell has the phenotype SS; sickle trait is one S and the other is a normal hgb (A) and is heterozygous. The abnormal hemoglobin causes the red blood cell to deform into a sickle shape under lower oxygen tension. This banana shape plugs up the small capillaries (doesn't flow like the normal red cell) which causes infarcs and pain.

Hemoglobin S differs from normal adult hemoglobin A only by a single amino acid substitution (a valine replacing a glutamine in the 6th position of the beta chain of the globin portion of the molecule).

I believe a cluster of genes code for hemoglobin.  (+ info)

How fast does the average human sperm cell travel?

And also, how long does it take on average for the human sperm cell to make it to the female egg cell after ejaculation?

Sperm can get into the fallopian tubes within 5 minutes after ejaculation, but it can take up to an hour. But the first sperm usually cannot fertilize the egg. It takes sperm many hours inside the cervix, uterus, or fallopian tubes before it's ready to fertilize the egg, this is called capacitation. During capacitation, the outside of the sperm is prepared for entry into the egg.  (+ info)

How many people are finding that the Cell Tower near them is making them ill?

As cell towers are being put up at a rapid pace, residents who do not even know about them are suddenly having health problems. They compare notes with neighbours and realize it is indeed the cell phone radiation emitting 24/7. Some areas were able to remove the antenna and their health returned.

No one.

Mobile phone towers do not emit enough radio waves to be dangerous.

Those that think the mobile phone tower made them ill were probably perfectly fine, just deluded into believing that their health suffered because they heard that mobile phones were dangerous or something.

"residents who do not even know about them are suddenly having health problems."
Exactly, those who know about them tend to understand enough not to be scared of health problems and thus not to suffer from psychosomatic symptoms.

"They compare notes with neighbours and realize it is indeed the cell phone radiation emitting 24/7."
By comparing notes?

Not exactly a double blind study. Did anyone even try to measure the microwaves from the tower?

"Some areas were able to remove the antenna and their health returned."
Maybe a tower could be built there and never operated and we'll see if their health gets worse.

If it was a psychological problem (which I suspect it was) then removing the antenna would appear to 'fix' it by removing their fear but it wasn't the best course of action because they still have an irrational fear of low power microwave transmitters.  (+ info)
