Sickle-Cell Disease

Sickle-cell anemia

Hemoglobin.

You get to live to 40, get free medication, eat alot of candy, and be very cold all the time.

It can be as low as 4 days.

My son Raman studing LKG - A sec in our school. He was not able to came to attended the classes on 4th July 2012 due to ill. kind permission is requested to allow him.

it has to do with inherited blood disorder that affects red blood sells

Neither. People with sickle cell anemia have the same number of chromosomes and even the same number of genes as those who don't have the disease. The difference is a *change* in one of the genes. Actually, it is (usually) caused by a one letter difference in the hemoglobin gene which makes the hemoglobin produced more 'sticky' on a molecular level.

the word sickle comes from the latin sikia meaning "annoyance" the rest of the word was just put in because the guys wo invented it were a*s holes.......

........got you, fool

this is a disease, not an odor, so it does not smell.

If a person has a single sickle cell allele they will have some sickles red blood cells, and some normal red blood cells. This is the origami purpose that this evolved for. If a person had a single sickle cell allele, they will be mostly resistant to malaria. This is why sickle cell anemia is most prevalent in areas of the world where malaria is common. However, if a person has two sickle cell anemia alleles, they will have ONLY sickled red blood cells. The "sickling" of the red blood cells is caused by a mutation in the protien that the gene codes for. That protein is hemoglobin, which carries oxygen through the blood. If a person has sickle cell anemia, parts of their body wil not get enough oxygen. They can pass out, loose sensation in the limb, or even die from it. In short, a person with two alleles is sick, and a person with one allele is not.

The sickle cell allele can be maintained in the central African population, above the frequency of gene mutation (balancing selection), because the heterozygous sickle cell individuals have an advantage in lifespan, in this malaria stricken region, over the homozygous alternatives. Homozygous sickle-sickle individuals die early from the sickle cell disease. Homozygous nonsickle-nonsickle die early from malaria. The heterozygous sickle-nonsickle have a higher survival against malaria and therefore the sickle cell allele is balanced selected.

The chemical components of ammonia is one part of nitrogen and 3 parts of hydrogen. The chemical symbol is NH3.

A chicken sickle is a group of bladed Chinese weapons that can be used as a single or double weapon. They include the Chicken-claw and Chicken-saber. The function of these are offensive and defensive in protecting one's property.

Another chicken sickle is the long, draping curved sickle feathers in the tail of roosters. Many times these feathers are green, a color you will not find in the hen. There is not a specific function for these feathers except to identify a rooster versus a hen.

autosomal recessive

No, drug test look for specific chemicals.

they are both inherited by two parents>

Conveys a health advantage to those who carry the allele

yes

Thalassemia

Not necessarily,

It is true that viruses hijack endocytotic mechanisms for their own gain in a "trojan horse" style as do bacterium but these pathways are alredy present on ever cell.

Macropinocytosis is used to traffick fluis into the cells and other smaller endocytotic routes are vital for cell homeostasis.

Infact, without endocytosis, cells fail to live or develope disease.

Famously, Alzheimer's Disease is caused by a dysfunction in endocytosis as are some cancers.

The full question is: What statement about sickle cell anemia is not true

A a serious genetic blood disorder affects red blood cells

B crescent shaped RBCs have difficulty passing through small blood vessels

C Blood vessels blocked by sickled cells can cause severe pain serious infections and organ damage

D is easily cured with proper treatment

D is easily cured with proper treatment is not true. The disease can be managed but not cured.

Sickle cell trait is an inherited blood disorder that affects 1 million to 3 million Americans and 8 to 10 percent of African Americans. Sickle cell trait can also affect Hispanics, South Asians, Caucasians from southern Europe, and people from Middle Eastern countries.

heme

Yes, I can honestly say that it has helped my 2 duaghters ages 9 and 17 who have this disease. It has improved with circulation and their immune systems. I am very happy with this.
